ITEM 5.  Other Events

     On  July  29,  1998,  Norwest  Asset  Securities  Corporation,  a  Delaware
corporation (the "Registrant"),  sold Mortgage Pass-Through Certificates, Series
1998-19,  Class 1-A-1, Class 1-B-1, Class 1-B-2, Class 1-B-3, Class 2-A-1, Class
2-A-2,  Class 2-A-3,  Class 2-A-4,  Class 2-A-5, Class 2-A-6, Class 2-A-7, Class
2-A-8, Class 2-A-9, Class 2-A-10, Class 2-A-11, Class 2-A-12, Class 2-A-R, Class
2-A-LR,  Class 2-B-1, Class 2-B-2 and Class 2-B-3 (the "Offered  Certificates"),
having an aggregate  original  principal  balance of  $471,932,000.  The Offered
Certificates were issued pursuant to a Pooling and Servicing Agreement, dated as
of July 29,  1998,  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 1998-19,
Class  1-A-PO  and  Class  2-A-PO  Certificates  (having  an  aggregate  initial
principal balance of $561,461.79),  and Class 1-B-4,  Class 1-B-5,  Class 1-B-6,
Class 2-B-4,  Class  2-B-5,  and Class 2-B-6  Certificates  (having an aggregate
initial principal balance of $3,331,610.18)  (the "Private Class B Certificates"
and,  together  with the Class  1-A-PO  and Class  2-A-PO  Certificates  and the
Offered  Certificates,  the  "Certificates"),  were also issued  pursuant to the
Agreement.

     As of the date of initial issuance,  the Offered Certificates  evidenced an
approximate  99.18%  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,
other than the Fixed  Retained Yield (as defined in this  Agreement),  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
1-A-PO,  2-A-PO and Private Class B Certificates.  Distributions  on the Private
Class  B  Certificates   are   subordinated  to  distributions  on  the  Offered
Certificates, Class 1-A-PO and Class 2-A-PO 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 1-A-1,  Class 1-A-PO,  Class 1-B-1, Class 1-B-2, Class
1-B-3,  Class 1-B-4,  Class 1-B-5,  Class 1-B-6, Class 2-A-1, Class 2-A-2, Class
2-A-3,  Class 2-A-4,  Class 2-A-5,  Class 2-A-6, Class 2-A-7, Class 2-A-8, Class
2-A-9,  Class 2-A-10,  Class 2-A-11,  Class 2-A-12,  Class 2-A-PO,  Class 2-B-1,
Class 2-B-2,  Class 2-B-3, Class 2-B-4, Class 2-B-5 and Class 2-B-6 Certificates
will be treated as "regular  interests"  in the  Upper-Tier  REMIC and the Class
2-A-R and Class 2-A-LR Certificate will be treated as the "residual interest" in
the "Upper-Tier REMIC" and "Lower-Tier REMIC", respectively.

Balance if such  Distribution  Date occurs  during or after  August  2007.  With
respect to any Distribution Date on which the Class 1-A Prepayment Percentage is
reduced below the Class 1-A  Prepayment  Percentage  for the prior  Distribution

Date,  weighted on the basis of the respective  Scheduled  Principal Balances of
such Mortgage Loans.

acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof.  When such execution is by
a signer acting in a capacity  other than his or her individual  capacity,  such
certificate or affidavit  shall also constitute  sufficient  proof of his or her
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the individual executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

Seller or the Master  Servicer in reliance  thereon,  whether or not notation of
such action is made upon such Certificate.

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 (other than
the  portion,  if any,  representing  the Fixed  Retained  Yield) 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, (d)
all of the Seller's right, title and interest in and to each Mortgage 100 Pledge
Agreement  and  each  Parent  Power(R)  Guaranty  and  Security   Agreement  for
Securities Account with respect to each Additional  Collateral Mortgage Loan and
(e) 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 the applicable 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 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, less any Fixed Retained Yield,  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  appropriate  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  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, the Master Servicer or the 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  Master
     Servicer or any of its assets;

          (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
Agreement,  with respect to the Mortgage  Loans,  or each Mortgage  Loan, as the
case may be:

     herein,  the Seller was the sole owner and holder of the Mortgage Loan free
     and clear of any and all liens,  pledges,  charges or security interests of
     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
     or charges or any lien of any assignment of rents or  maintenance  expenses
     secured by the real property owned by the cooperative housing  corporation;
     and any security agreement, chattel mortgage or equivalent document related

     Note in any  material  respect,  satisfied,  canceled or  subordinated  the
     Mortgage in whole or in part,  released the Mortgaged  Property in whole or
     in part  from the lien of the  Mortgage,  or  executed  any  instrument  of
     release, cancellation, modification or satisfaction, except in each case as
     is  reflected in an  agreement  delivered  to the Trustee or the  Custodian
     pursuant to Section 2.01;

     permitted by law, in an amount  sufficient to pay for every such item which
     remains  unpaid;  and the Seller has not  advanced  funds,  or received any
     advance  of  funds  by a  party  other  than  the  Mortgagor,  directly  or
     indirectly  (except  pursuant  to any  Subsidy  Loan  arrangement)  for the
     payment  of any  amount  required  by the  Mortgage,  except  for  interest
     accruing from the date of the Mortgage Note or date of  disbursement of the

     casualty  (excluding  casualty  from the  presence of  hazardous  wastes or
     hazardous substances, as to which the Seller makes no representations),  so
     as to affect adversely the value of the Mortgaged  Property as security for
     the Mortgage  Loan or the use for which the premises  were  intended 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
     this  warranty  shall be  deemed  not to have  been made at the time of the
     initial  issuance  of the  Certificates  if a title  policy  affording,  in
     substance,  the same  protection  afforded by this warranty is furnished to
     the Trustee by the Seller;

          (viii) Except for Mortgage  Loans secured by Co-op Shares and Mortgage

     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 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

     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

     insurance policy;

          (xvi) The Mortgaged Property securing each Mortgage Loan is insured by

     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 National  Flood  Insurance  Act of 1968, as
     amended;  and each Mortgage obligates the Mortgagor  thereunder to maintain
     all such insurance at the Mortgagor's cost and expense;

          (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 180
     months (in the case of a Pool I Mortgage  Loan) or; 360 months (in the case
     of a Pool II Mortgage Loan).

          (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(a)(3) 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

          (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 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  applicable  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
Certificateholders  or the  Trustee  on behalf of  Certificateholders,  and such
obligation shall survive until termination of the Trust Estate hereunder.

     Section 2.04. Execution and Delivery of Certificates.

     The Trustee acknowledges the assignment to it of the Mortgage Loans and the
delivery of the Owner  Mortgage  Loan Files to it, and,  concurrently  with such
delivery, (i) acknowledges the issuance of and hereby declares that it holds the
Uncertificated  Lower-Tier  Interests  on  behalf  of the  Upper-Tier  REMIC and
Certificateholders  and (ii) has executed and  delivered to or upon the order of
the Seller,  in exchange for the Mortgage  Loans and  Uncertificated  Lower-Tier
Interests  together with all other assets  included in the  definition of "Trust
Estate",  receipt of which is hereby  acknowledged,  Certificates  in authorized
denominations  which,  together with the  Uncertificated  Lower-Tier  Interests,
evidence ownership of the entire Trust Estate.

     Section 2.05.  Designation of Certificates;  Designation of Startup Day and
Latest Possible Maturity Date.

     The Seller hereby  designates  the Classes of Class A  Certificates  (other
than the Class 2-A-R and Class 2-A-LR  Certificates)  and the Classes of Class B
Certificates as classes of "regular  interests" and the Class 2-A-R  Certificate
as the single  class of  "residual  interest"  in the  Upper-Tier  REMIC for the
purposes of Code Sections  860G(a)(1) and 860G(a)(2),  respectively.  The Seller
hereby further  designates the Class 1-A-L1  Interest,  Class 1-A-LPO  Interest,

2-B-L2  Interest,  Class 2-B-L3 Interest,  Class 2-B-L4  Interest,  Class 2-B-L5
Interest and Class  2-B-L6  Interest as classes of "regular  interests"  and the
Class  2-A-LR  Certificate  as the single  class of  "residual  interest" in the
Lower-Tier  REMIC for the purposes of Code Sections  860G(a)(1) and  860G(a)(2),
respectively. The Closing Date is hereby designated as the "Startup Day" of each
of the Upper-Tier  REMIC and Lower-Tier REMIC within the meaning of Code Section

ADMINISTRATION OF THE TRUST ESTATE:  SERVICING
OF THE MORTGAGE LOANS

     Section 3.01. Certificate Account.

     (a) The Master  Servicer shall  establish and maintain a Pool I Certificate
Account for the deposit of funds received by the Master Servicer with respect to
the Pool I Mortgage Loans and a Pool II  Certificate  Account for the deposit of
funds  received by the Master Service with respect to the Pool II Mortgage Loans
serviced by each  Servicer  pursuant to each of the Servicing  Agreements.  Each
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
applicable Certificate Account and of any change in the location thereof.

     (b) The Master  Servicer shall deposit into the Pool I Certificate  Account
or  Pool II  Certificate  Account  on the day of  receipt  thereof  all  amounts
received by it from any  Servicer  pursuant to any of the  Servicing  Agreements
with  respect  to  the  Pool  I  Mortgage  Loans  or  Pool  II  Mortgage  Loans,
respectively, or with respect to the Pool I Mortgage Loans, any amounts received
by it upon the sale of any  Additional  Collateral  pursuant  to the  terms of a
Mortgage  100 Pledge  Agreement  or the Parent  Power(R)  Guaranty  and Security
Agreement for Securities  Account or any amounts received pursuant to the Surety
Bond and shall, in addition, deposit into the Pool I Certificate Account or Pool
II 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 any amounts  deemed  received by the
     Master Servicer pursuant to Section 3.01(d); 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 a 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  applicable
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 applicable  Certificate Account by the Master Servicer
out of its own funds immediately as realized.

     (d) For purposes of this  Agreement,  the Master Servicer will be deemed to
have received from a Servicer on the applicable  Remittance  Date for such funds
all  amounts  deposited  by such  Servicer  into the  Custodial  Account for P&I
maintained  in  accordance  with the  applicable  Servicing  Agreement,  if such
Custodial  Account  for  P&I is not an  Eligible  Account  as  defined  in  this
Agreement,  to the extent such amounts are not  actually  received by the Master
Servicer  on such  Remittance  Date as a result of the  bankruptcy,  insolvency,
receivership or other financial distress of the depository  institution in which
such  Custodial  Account  for P&I is being held.  To the extent that  amounts so
deemed to have been received by the Master Servicer are subsequently remitted to
the Master  Servicer,  the Master  Servicer  shall be  entitled  to retain  such
amounts.

     Section 3.02. Permitted Withdrawals from the Certificate Accounts.

     (a) The Master Servicer may, from time to time, make  withdrawals  from the
applicable  Certificate  Account (such  withdrawals being limited in the case of
the Pool I  Certificate  Account to  withdrawals  related to the Pool I Mortgage
Loans and the Group 1  Certificates  and in the case of the Pool II  Certificate
Account to  withdrawals  related to the Pool II  Mortgage  Loans and the Group 2
Certificates)  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
     Periodic  Advances made by the Master  Servicer or the Trustee  pursuant to
     Section  3.03(a) or any Servicer  pursuant to any Servicing  Agreement with
     respect  to  previous  Distribution  Dates,  such  right  to  reimbursement
     pursuant to this  subclause (i) being limited to amounts  received on or in
     respect  of  particular  Mortgage  Loans  (including,   for  this  purpose,
     Liquidation  Proceeds,  REO Proceeds and proceeds from the purchase,  sale,
     repurchase or  substitution  of Mortgage  Loans  pursuant to Sections 2.02,
     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
     any   Periodic   Advances   determined   in  good  faith  to  have   become
     Nonrecoverable   Advances   provided,   however,   that  any   portion   of
     Nonrecoverable   Advances   representing  Fixed  Retained  Yield  shall  be
     reimbursable  only from amounts  constituting  Fixed Retained Yield and not
     from the assets of the Trust Estate;

          (iii)  to  reimburse   the  Master   Servicer  or  any  Servicer  from
     Liquidation  Proceeds for Liquidation  Expenses and for amounts expended by
     the Master  Servicer or any Servicer  pursuant  hereto or to any  Servicing
     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
     purchased  pursuant to Section 3.08 or 9.01, all amounts  received  thereon
     and not  required  to be  distributed  as of the date on which the  related
     repurchase or purchase price or Scheduled Principal Balance was determined;

          (vii) to remit  funds to the Paying  Agent in the  amounts  and in the
     manner provided for herein;

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

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

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

          (xi) to clear and terminate a Certificate  Account pursuant to Section
     9.01; and

          (xii) to pay to Norwest Mortgage from any Mortgagor payment on account
     of interest or other recovery  (including Net REO Proceeds) with respect to
     a particular  Mortgage Loan, the Fixed Retained Yield, if any, with respect
     to such Mortgage Loan; provided,  however, that with respect to any payment
     of interest  received by the Master  Servicer in respect of a Mortgage Loan
     (whether  paid  by the  Mortgagor  or  received  as  Liquidation  Proceeds,
     Insurance  Proceeds  or  otherwise)  which is less than the full  amount of
     interest then due with respect to such Mortgage Loan,  only that portion of
     such  payment of  interest  that bears the same  relationship  to the total
     amount of such  payment of interest as the Fixed  Retained  Yield Rate,  if
     any, in respect of such Mortgage  Loan bears to the Mortgage  Interest Rate
     shall be allocated to the Fixed Retained Yield with respect thereto.

     (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 applicable 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 addition, if under the terms
of an Other Servicing Agreement, the applicable Servicer is not required to make
Periodic  Advances  on  a  Mortgage  Loan  or  REO  Mortgage  Loan  through  the
liquidation of such Mortgage Loan or REO Mortgage  Loan, the Master  Servicer to
the extent provided hereby shall make the Periodic  Advances  thereon during the
period the  Servicer is not  obligated to do so. 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 by Norwest Mortgage or such Other Servicer,  (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  applicable  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 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 applicable 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 appropriate  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 a  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 a 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 a  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
applicable  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 applicable 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,  unless (i) the
Mortgage Loan has been liquidated and the Liquidation  Proceeds  relating to the
Mortgage Loan have been deposited in the appropriate 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 appropriate  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 a
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
each 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 each such  account  for each  category  of
deposit and withdrawal  specified in Sections 3.01 and 3.02. Such statements 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 the Pool I Mortgage Loans and Pool II Mortgage  Loans,  as applicable,  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.

     (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 appropriate  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.

     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).

     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  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  to  repurchase  at its option 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.  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 for such Mortgage Loan,  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 appropriate 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.  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.

     Additional  Collateral may be liquidated and the proceeds  applied to cover
any shortfalls upon the liquidation of a Mortgaged Property;  provided, however,
that the Trust  Estate in no event shall  acquire  ownership  of the  Additional
Collateral  unless the Trustee  shall have  received an Opinion of Counsel  that
such  ownership  shall  not cause the  Trust  Estate to fail to  qualify  as two
separate REMICs or subject either REMIC to any tax.

     The Master  Servicer may enter into a special  servicing  agreement with an
unaffiliated  holder  of  100%  Percentage  Interest  of  a  Class  of  Class  B
Certificates 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  Pool I or Pool II Mortgage  Loans,  as
applicable,  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)
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. Application of Net Liquidation Proceeds.

     For all purposes under this agreement,  Net Liquidation  Proceeds  received
from a Servicer shall be allocated  first to accrued and unpaid  interest on the
related Mortgage Loan and then to the unpaid principal balance thereof.

     Section 3.11. 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 1-A-PO and Class 2-A-PO Certificates) and the Class 1-B-1,
Class 1-B-2,  Class 1-B-3, Class 2-B-1, Class 2-B-2 and Class 2-B-3 Certificates
pursuant to the Securities Exchange Act of 1934, as amended.

     (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  or
Classes as provided  herein.  On each  Distribution  Date,  each  Uncertificated
Lower-Tier  Interest  (other  than  the  Class  2-A-L1  Interest,  Class  2-A-L3
Interest,  Class  2-A-L5  Interest,  Class  2-A-L6  Interest  and  Class  2-A-L7

Group 1 Interest Accrual Amounts,  Group 1 Unpaid Interest  Shortfalls,  Group 2
Interest Accrual Amounts and Group 2 Unpaid Interest Shortfalls, as the case may
be, in respect of its Corresponding Upper-Tier Class or Classes, in each case to
the  extent  actually   distributed  (or,  in  the  case  of  the  Class  2-A-11
Certificates,  added to their  Principal  Balance)  thereon.  The  Class  2-A-L1
Interest shall receive  distributions  in respect of interest in an amount equal
to the sum of (i) the  amount of  interest  distributed  on the Class  2-A-1 and
Class 2-A-2  Certificates  and (ii) an amount  equal to the product of the Class
2-A-L1  Interest  Fraction and the amount of interest  distributed  on the Class
2-A-8  Certificates.  The Class 2-A-L3 Interest shall receive  distributions  in
respect of interest in an amount  equal to the sum of (i) the amount of interest
distributed on the Class 2-A-3 and Class 2-A-4  Certificates  and (ii) an amount
equal to the product of the Class  2-A-L3  Interest  Fraction  and the amount of
interest distributed on the Class 2-A-8 Certificates.  The Class 2-A-L5 Interest
shall receive distributions in respect of interest in an amount equal to the sum
of (i) the amount of interest  distributed on the Class 2-A-5  Certificates  and
(ii) an amount  equal to the product of the Class 2-A-L5  Interest  Fraction and
the amount of interest  distributed on the Class 2-A-8  Certificates.  The Class
2-A-L6 Interest shall receive  distributions in respect of interest in an amount
equal to the sum of (i) the amount of  interest  distributed  on the Class 2-A-6
Certificates  and  (ii) an  amount  equal to the  product  of the  Class  2-A-L6
Interest  Fraction  and the amount of  interest  distributed  on the Class 2-A-8
Certificates The Class 2-A-L7 Interest shall receive distributions in respect of
interest in an amount equal to the sum of (i) the amount of interest distributed
on the Class 2-A-7  Certificates  and (ii) an amount equal to the product of the
Class 2-A-L7  Interest  Fraction and the amount of interest  distributed  on the
Class  2-A-8  Certificates.  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  equals  the  Principal   Balances  of  the  respective   Corresponding
Upper-Tier   Class  or   Classes.   The  initial   principal   balance  of  each
Uncertificated Lower-Tier Interest equals the Original Principal Balances of the
respective Corresponding Upper-Tier Class or Classes.

     The  pass-through  rate with  respect to the Class 1-A-L1  Interest,  Class
1-B-L1  Interest,  Class 1-B-L2 Interest,  Class 1-B-L3  Interest,  Class 1-B-L4
Interest,  Class 1-B-L5  Interest and Class 1-B-L6  Interest shall be 6.500% per

2-A-L3  Interest,  Class 2-A-L5 Interest,  Class 2-A-L6  Interest,  Class 2-A-L7
Interest,  Class 2-A-L9 Interest, Class 2-A-Ll1 Interest, Class 2-B-L1 Interest,
Class 2-B-L2  Interest,  Class 2-B-L3  Interest,  Class 2-B-L4  Interest,  Class
2-B-L5 Interest and Class 2-B-L6  Interest shall be 6.750% per annum.  The Class
1-A-LPO Interest and Class 2-A-LPO Interest are principal-only interests and are
not entitled to  distributions of interest.  Any Group 1 Non-Supported  Interest
Shortfalls will be allocated to the Group 1 Uncertificated  Lower-Tier Interests
in the same relative proportions as interest is allocated to such Uncertificated
Lower-Tier Interests,  and any Group 2 Non-Supported Interest Shortfalls will be
allocated  to the  Group  2  Uncertificated  Lower-Tier  Interests  in the  same
relative proportions as interest is allocated to such Uncertificated  Lower-Tier
Interests.

     (b) On each Distribution Date, the Class 1-A Non-PO Principal  Distribution
Amount for the Class 1-A  Certificates  will be  distributed in reduction of the
Principal  Balance of the Class 1-A-1  Certificates  until the Principal Balance
thereof has been reduced to zero.

     The Class 2-A-8  Certificates  are  interest-only  Certificates and are not
entitled to distributions in respect of principal.

     On each  Distribution Date prior to the Group II Cross-Over Date, the Class
2-A Non-PO Principal  Distribution Amount for the Class 2-A Certificates will be

     (c) Notwithstanding  the foregoing,  on each Distribution Date occurring on
or subsequent  to the Group 2 Cross-Over  Date,  the Class 2-A Non-PO  Principal
Distribution  Amount  shall be  distributed  among  the  Classes  of  Class  2-A
Certificates  (other than the Class 2-A-PO  Certificates) pro rata in accordance
with  their  outstanding   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  Classes  of  Class B
Certificates  of any Group are  eligible to receive  distributions  of principal
with respect to any Distribution Date, the following tests shall apply:

          (A) (i) if the Current  Class 1-B-1  Fractional  Interest is less than
     the Original Class 1-B-1 Fractional  Interest and the Class 1-B-1 Principal
     Balance is greater than zero,  the Class 1-B-2,  Class 1-B-3,  Class 1-B-4,
     Class 1-B-5 and Class 1-B-6  Certificates  shall not be eligible to receive
     distributions of principal; or

               (ii) if the Current Class 2-B-1 Fractional  Interest is less than
     the Original Class 2-B-1 Fractional  Interest and the Class 2-B-1 Principal
     Balance is greater than zero,  the Class 2-B-2,  Class 2-B-3,  Class 2-B-4,
     Class 2-B-5 and Class 2-B-6  Certificates  shall not be eligible to receive
     distributions of principal; or

          (B) (i) if the Current  Class 1-B-2  Fractional  Interest is less than
     the Original Class 1-B-2 Fractional  Interest and the Class 1-B-2 Principal
     Balance is greater than zero, the Class 1-B-3, Class 1-B-4, Class 1-B-5 and
     Class 1-B-6 Certificates shall not be eligible to receive  distributions of
     principal; or

               (ii) if the Current Class 2-B-2 Fractional  Interest is less than
     the Original Class 2-B-2 Fractional  Interest and the Class 2-B-2 Principal
     Balance is greater than zero, the Class 2-B-3, Class 2-B-4, Class 2-B-5 and
     Class 2-B-6 Certificates shall not be eligible to receive  distributions of
     principal; or

          (C) (i) if the Current  Class 1-B-3  Fractional  Interest is less than
     the Original Class 1-B-3 Fractional  Interest and the Class 1-B-3 Principal
     Balance is greater than zero, the Class 1-B-4,  Class 1-B-5 and Class 1-B-6
     Certificates  shall not be eligible to receive  distributions of principal;
     or

               (ii) if the Current Class 2-B-3 Fractional  Interest is less than
     the Original Class 2-B-3 Fractional  Interest and the Class 2-B-3 Principal
     Balance is greater than zero, the Class 2-B-4,  Class 2-B-5 and Class 2-B-6
     Certificates  shall not be eligible to receive  distributions of principal;
     or

          (D) (i) if the Current  Class 1-B-4  Fractional  Interest is less than
     the Original Class 1-B-4 Fractional  Interest and the Class 1-B-4 Principal
     Balance is greater than zero, the Class 1-B-5 and Class 1-B-6  Certificates
     shall not be eligible to receive distributions of principal; or

               (ii) if the Current Class 2-B-4 Fractional  Interest is less than
     the Original Class 2-B-4 Fractional  Interest and the Class 2-B-4 Principal
     Balance is greater than zero, the Class 2-B-5 and Class 2-B-6  Certificates
     shall not be eligible to receive distributions of principal; or

          (E) (i) if the Current  Class 1-B-5  Fractional  Interest is less than
     the Original Class 1-B-5 Fractional  Interest and the Class 1-B-6 Principal
     Balance is greater  than zero,  the Class 1-B-6  Certificates  shall not be
     eligible to receive distributions of principal; or

               (ii) if the Current Class 2-B-5 Fractional  Interest is less than
     the Original Class 2-B-5 Fractional  Interest and the Class 2-B-5 Principal
     Balance is greater  than zero,  the Class 2-B-6  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 Classes of Class B Certificates of a
Group entitled to receive  distributions of principal would reduce the Principal
Balances  of the  Classes  of Class B  Certificates  of such Group  entitled  to
receive  distributions  of principal below zero,  first the Class 1-B Prepayment
Percentage  or Class  2-B  Prepayment  Percentage,  as the  case may be,  of any
affected  Class  of  Class  B  Certificates   in  the  related  Group  for  such
Distribution  Date beginning  with the affected Class with the lowest  numerical
Class designation and then, if necessary,  the Class 1-B Percentage or Class 2-B
Percentage as the case may be, of such Class of the Class B Certificates  in the
related  Group for such  Distribution  Date shall be  reduced to the  respective
percentages  necessary to bring the  Principal  Balance of such Class of Class B
Certificates in the related Group to zero. The Class 1-B Prepayment  Percentages
or Class  2-B  Prepayment  Percentages,  as the case may be,  and the  Class 1-B
Percentages  or Class  2-B  Percentages,  as the case may be,  of the  remaining
Classes  of  Class B  Certificates  in the  related  Group  will  be  recomputed
substituting  for the  Group 1  Subordinated  Prepayment  Percentage  or Group 2
Subordinated  Prepayment Percentage as the case may be, and Group 1 Subordinated
Percentage  or Group 2  Subordinated  Percentage,  as the  case may be,  in such
computations  the  difference  between (A) the Group 1  Subordinated  Prepayment
Percentage or Group 2 Subordinated Prepayment Percentage, as the case may be, or
Group 1 Subordinated Prepayment Percentage,  or Group 2 Subordinated Percentage,
as the case may be, and (B) the  percentages  determined in accordance  with the
preceding  sentence  necessary to bring the  Principal  Balances of the affected
Classes of Class B Certificates in such Group to zero; provided,  however,  that
if the  Principal  Balances  of all the Classes of Class B  Certificates  in the
related Group eligible to receive distributions of principal shall be reduced to
zero on such Distribution Date, the Class 1-B Prepayment Percentage or Class 2-B
Prepayment Percentage, as the case may be, and the Class 1-B Percentage or Class
2-B Percentage,  as the case may be, of the Class of Class B Certificates in the
related Group with the lowest numerical Class  designation which would otherwise
be ineligible  to receive  distributions  of principal in  accordance  with this
Section  shall  equal  the  remainder  of the  Group 1  Subordinated  Prepayment
Percentage or Group 2 Subordinated  Prepayment  Percentage,  as applicable,  for
such Distribution Date minus the sum of the Class 1-B Prepayment  Percentages or
Class 2-B Prepayment Percentages,  as the case may be, of the Classes of Class B
Certificates in the related Group having lower numerical Class designations,  if
any,  and the  remainder  of the  Group 1  Subordinated  Percentage  or  Group 2
Subordinated  Percentage,  as the case may be, for such  Distribution Date minus
the sum of the Class 1-B Percentages or Class 2-B Percentages, as applicable, of
the Classes of Class B Certificates  in the related Group having lower numerical
Class designations, if any, respectively.  Any entitlement of any Class of Class
B Certificates  in the related Group to principal  payments  solely  pursuant to
this clause (ii) shall not cause such Class to be regarded as being  eligible to
receive  principal  distributions  for the purpose of applying the definition of
its Class 1-B Percentage or Class 2-B  Percentage,  as applicable,  or Class 1-B
Prepayment Percentage or Class 1-B Prepayment Percentage, as applicable.

     (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  2-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 2-A Distribution  Amount with respect to the Class 2-A-LR  Certificate and
all other amounts distributable to the Class 2-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 2-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)
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 having a Denomination at
least equal to that specified in Section  11.24,  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 2-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 of the Class 1-A  Distribution
Amount or Class 2-A Distribution  Amount with respect to each Class of Class 1-A
Certificates  or  Class  2-A  Certificates,  respectively,  and  the  Class  1-B
Distribution  Amount or Class 2-B Distribution  Amount with respect to each such
Class of Class 1-B Certificates or Class 2-B Certificates, respectively.

     In the event that, on any Distribution Date prior to the Final Distribution
Date, the Principal Balance of any Class of Class A Certificates (other than the
Class 2-A-8, Class 2-A-R or Class 2-A-LR  Certificates) or the Principal Balance
of any Class of Class B Certificates would be reduced to zero, or in the case of
the Class 2-A-8  Certificates,  the Class 2-A-8 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  with a copy to the  Certificate  Registrar,  specifying  that  the  final
distribution  with respect to such Class 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 (except to the extent provided in applicable
Treasury  regulations) 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 a court  within  the  United  States  is able to  exercise
primary  supervision over the administration of such trust, and one or more such
U.S.  Persons have the  authority to control all  substantial  decisions of such
trust (or, to the extent provided in applicable  Treasury  regulations,  certain
trusts in existence on August 20, 1996 which are eligible to elect to be treated
as U.S. Persons).

     Section 4.02. Allocation of Realized Losses.

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

     first,  to the Class 1-B-6  Certificates  until the Class  1-B-6  Principal
Balance has been reduced to zero;

     second,  to the Class 1-B-5  Certificates  until the Class 1-B-5  Principal
Balance has been reduced to zero;

     third,  to the Class 1-B-4  Certificates  until the Class  1-B-4  Principal
Balance has been reduced to zero;

     fourth,  to the Class 1-B-3  Certificates  until the Class 1-B-3  Principal
Balance has been reduced to zero;

     fifth,  to the Class 1-B-2  Certificates  until the Class  1-B-2  Principal
Balance has been reduced to zero;

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

     seventh,  concurrently,  to the Class 1-A-1  Certificates  and Class 1-A-PO
Certificates,  pro rata,  based on the Pool I Non-PO  Fraction and the Pool I PO
Fraction, respectively.

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

     first,  to the Class 2-B-6  Certificates  until the Class  2-B-6  Principal
Balance has been reduced to zero;

     second,  to the Class 2-B-5  Certificates  until the Class 2-B-5  Principal
Balance has been reduced to zero;

     third,  to the Class 2-B-4  Certificates  until the Class  2-B-4  Principal
Balance has been reduced to zero;

     fourth,  to the Class 2-B-3  Certificates  until the Class 2-B-3  Principal
Balance has been reduced to zero;

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

     sixth,  to the Class 2-B-1  Certificates  until the Class  2-B-1  Principal
Balance has been reduced to zero; and

     seventh,  concurrently, to the Class 2-A Certificates (other than the Class
2-A-PO Certificates) and Class 2-A-PO Certificates,  pro rata, based on the Pool
II Non-PO Fraction and the Pool II PO Fraction, respectively.

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

     (b) (i) With respect to any  Distribution  Date,  the principal  portion of
Pool I Excess  Special  Hazard  Losses,  Pool I Excess  Fraud  Losses and Pool I
Excess  Bankruptcy  Losses,  occurring  with respect to any Pool I Mortgage Loan
allocable to the Class 1-A-PO  Certificates will equal the product of the amount
of any such  principal  loss and the Pool I PO Fraction for such Pool I Mortgage
Loan. The principal  portion of any Pool I Excess Special Hazard Losses,  Pool I
Excess  Fraud  Losses  and  Pool I  Excess  Bankruptcy  Losses  remaining  after
allocation to the Class 1-A-PO  Certificates  in  accordance  with the preceding
sentence  shall be allocated pro rata between the Class 1-A-1  Certificates  and
Class 1-B Certificates based on the Class 1-A Non-PO Principal Balance,  and the
Class  1-B  Principal  Balance.  Any  such  loss  allocated  to  the  Class  1-B
Certificates shall be allocated pro rata among the outstanding  Classes of Class
1-B Certificates based on their Class 1-B Principal Balances.

         (ii) With respect to any  Distribution  Date, the principal  portion of
Pool II Excess Special  Hazard  Losses,  Pool II Excess Fraud Losses and Pool II
Excess  Bankruptcy  Losses,  occurring with respect to any Pool II Mortgage Loan
allocable to the Class 2-A-PO  Certificates will equal the product of the amount
of any such principal loss and the Pool II PO Fraction for such Pool II Mortgage
Loan. The principal portion of any Pool II Excess Special Hazard Losses, Pool II
Excess  Fraud  Losses  and Pool II  Excess  Bankruptcy  Losses  remaining  after
allocation to the Class 2-A-PO  Certificates  in  accordance  with the preceding
sentence  shall be allocated  pro rata among the Class 2-A  Certificates  (other
than the Class 2-A-PO  Certificates),  and Class 2-B  Certificates  based on the
Class 2-A Non-PO Principal  Balance,  and the Class 2-B Principal  Balance.  Any
such loss  allocated  to the Class 2-A  Certificates  shall be  allocated on the
subsequent  Determination  Date  among  the  outstanding  Classes  of Class  2-A
Certificates  (other than the Class 2-A-PO  Certificates) in accordance with the
Class  2-A  Loss  Percentages  as of such  Determination  Date.  Any  such  loss
allocated to the Class 2-B  Certificates  shall be allocated  pro rata among the
outstanding Classes of Class 2-B Certificates based on their Class 2-B Principal
Balances.

     (c) Any Realized  Losses  allocated to a Class of Class A  Certificates  or
Class B Certificates within a Group of Certificates  pursuant to Section 4.02(a)
or Section 4.02(b) shall be allocated among the Certificates of such 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  Classes  of  Class  A  Certificates,  or any  Classes  of  Class B
Certificates,  each outstanding Class to which such Realized Loss had previously
been allocated  shall be entitled to its share (with respect to the Class 1-A-PO
Certificates  or Class 2-A-PO  Certificates,  based on the Pool I PO Fraction or
Pool II PO  Fraction  of such  Mortgage  Loan and,  with  respect to the Class A
Certificates  (other than the Class 1-A-PO and Class 2-A-PO  Certificates),  and
Class B  Certificates,  based  on  their  pro  rata  share  of the Pool I Non-PO
Fraction or Pool II Non-PO  Fraction,  as applicable,  of such Mortgage Loan) of
such  Recovery up to the amount of such Realized  Loss  previously  allocated to
such Class on the  Distribution  Date in the month  following the month in which
such recovery is received. When the Principal Balance of a Class of Certificates
has been reduced to zero,  such Class 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  in  accordance  with the
preceding  provisions,  each outstanding Class 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.  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 applicable  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  of each Class of
Certificates  whose principal  balances were  previously  reduced as a result of
such  Realized  Loss  being less than such Class  would  have  received  if such
Recovery had been deposited in the appropriate  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) (i) The interest portion of Pool I Excess Special Hazard Losses, Pool I
Excess  Fraud  Losses and Pool I Excess  Bankruptcy  Losses  shall be  allocated
between the Class 1-A-1 Certificates and Class 1-B Certificates,  pro rata based
on the Class 1-A  Interest  Accrual  Amount and the Class 1-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 1-B Certificates
will be allocated among the outstanding  Classes of Class 1-B Certificates based
on their  Class  1-B  Interest  Percentages.  In  addition,  after the Class 1-B
Principal  Balance have been reduced to zero,  the interest  portion of Realized
Losses  (other than Pool I Excess  Special  Hazard  Losses,  Pool I Excess Fraud
Losses and Pool I Excess Bankruptcy Losses) will be allocated to the Class 1-A-1
Certificates.

     (ii) The interest portion of Pool II Excess Special Hazard Losses,  Pool II
Excess  Fraud  Losses and Pool II Excess  Bankruptcy  Losses  shall be allocated
among the Class 2-A Certificates and Class 2-B  Certificates,  pro rata based on
the Class 2-A Interest  Accrual Amount and the Class 2-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 2-A  Certificates  shall be
allocated among the outstanding Classes of Class 2-A Certificates based on their
Class  2-A  Interest  Percentages.  Any such  loss  allocated  to the  Class 2-B
Certificates  will be  allocated  among  the  outstanding  Classes  of Class 2-B
Certificates based on their Class 2-B Interest Percentages.  In addition,  after
the Class 2-B Principal  Balance have been reduced to zero, the interest portion
of Realized  Losses (other than Pool II Excess Special  Hazard  Losses,  Pool II
Excess  Fraud  Losses and Pool II Excess  Bankruptcy  Losses)  will be allocated
among the outstanding Classes of Class 2-A Certificates based on their Class 2-A
Interest Percentages.

     (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.

     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
agent of the Master Servicer.

     The Master Servicer may, at any time, remove or replace the Paying Agent.

     The Master Servicer shall cause any Paying Agent that is not the Trustee to
execute  and  deliver to the Trustee an  instrument  in which such Paying  Agent
agrees with the Trustee that such Paying Agent shall:

          (i)  hold  all  amounts  remitted  to it by the  Master  Servicer  for
     distribution   to   Certificateholders   in  trust  for  the   benefit   of
     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  applicable  Certificate
Account  or,  to the  extent  required  hereunder,  from its own funds (i) at or

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.

proposed transferee of a Class 1-A-PO,  Class 1-B-4, Class 1-B-5 or Class 1-B-6,

     The Master  Servicer  shall, in each year beginning after the Cut-Off Date,
make the reports of foreclosures and  abandonments of any Mortgaged  Property as
required by Code Section 6050J. In order to facilitate  this reporting  process,
the Master Servicer shall request that each Servicer,  on or before January 15th
of each year, shall provide to the Internal Revenue Service,  with copies to the
Master Servicer, reports relating to each instance occurring during the previous
calendar  year in which such  Servicer (i) on behalf of the Trustee  acquires an
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
abandoned.  Reports from the Servicers shall be in form and substance sufficient
to meet the reporting  requirements  imposed by Code Section 6050J. In addition,
each Servicer shall provide the Master Servicer with  sufficient  information to
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.

     Section 4.07. Determination of LIBOR.

     On each Rate Determination  Date, the Trustee shall determine LIBOR for the
Distribution  Date occurring in the second  succeeding month on the basis of the
British Bankers'  Association  ("BBA") "Interest  Settlement Rate" for one-month
deposits in U.S.  dollars as found on Telerate page 3750 as of 11:00 A.M. London
time on such Rate Determination Date. As used herein, "Telerate page 3750" means
the display designated as page 3750 on the Dow Jones Telerate Service.

     If on any Rate  Determination Date the Trustee is unable to determine LIBOR
on the basis of the method set forth in the  preceding  paragraph  LIBOR for the
Distribution  Date in the second succeeding month will be whichever is higher of
(x) LIBOR as  determined  on the  previous  Rate  Determination  Date or (y) the
Reserve  Interest Rate.  The "Reserve  Interest Rate" will be the rate per annum
which the Trustee determines to be either (A) the arithmetic mean (rounding such
arithmetic  mean upwards if necessary to the nearest whole multiple of 1/16%) of
the one-month  Eurodollar lending rates that New York City banks selected by the
Trustee are quoting,  on the relevant Rate Determination  Date, to the principal
London offices of at least two leading banks in the London  interbank  market or
(B) in the event that the Trustee can  determine no such  arithmetic  mean,  the
lowest one-month  Eurodollar  lending rate that the New York City banks selected
by the Trustee are quoting on such Rate  Determination  Date to leading European
banks.

     If on any Rate  Determination Date the Trustee is required but is unable to
determine  the Reserve  Interest  Rate in the manner  provided in the  preceding
paragraph,  LIBOR for the Distribution  Date in the second succeeding month will
be LIBOR as determined on the previous Rate Determination  Date, or, in the case
of the first Rate Determination Date, 5.656%.

     The  establishment  of LIBOR by the  Trustee and the  Trustee's  subsequent
calculation  of the rates of interest  applicable  to the Class A-6,  Class A-7,
Class A-9 and Class A-10 Certificates, in the absence of manifest error, will be
final and binding.  After a Rate  Determination  Date, the Trustee shall provide
the  Pass-Through  Rates of the Class A-6,  Class A-7,  Class A-9 and Class A-10
Certificates for the related  Distribution  Date to Beneficial Owners or Holders
of Class A-6,  Class  A-7,  Class A-9 and Class  A-10  Certificates  who place a
telephone call to the Trustee at (704) 590-6161 and make a request therefor.

Certificates)  that  evidences  one  Single  Certificate  plus  such  additional
principal   portion  or  notional  amount  as  is  required  in  order  for  all
Certificates of such Class to equal the aggregate  Original Principal Balance or
notional amount of such Class,  as the case may be), and shall be  substantially
in the  respective  forms set forth as Exhibits  1-A-1,  1-A-PO,  1-B-1,  1-B-2,

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 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.

     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 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.

     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  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 1-A-PO,  Class 1-B-4,  1-Class B-5, Class 1-B-6,
Class 2-A-PO,  Class 2-B-4, Class 2-B-5 or Class 2-B-6 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  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 1-A-PO,  Class 1-B-4,  Class 1-B-5,
Class  1-B-6,   Class   2-A-PO,   Class  2-B-4,   Class  2-B-5  or  Class  2-B-6
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  (other than an  affiliate  of the Seller on the
Closing Date) to execute an investment  letter in the form of Exhibit J-1 or J-2
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 1-A-PO, Class 1-B-4, Class
1-B-5,  Class  1-B-6,  Class  2-A-PO,  Class  2-B-4,  Class 2-B-5 or Class 2-B-6
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 1-A-PO,  Class 1-B-4, Class 1-B-5, Class 1-B-6, Class 2-A-PO,
Class 2-B-4, Class 2-B-5 or Class 2-B-6 Certificates under said Act or any other
securities law.

     (c) No  transfer of a Class  1-A-PO,  Class  2-A-PO or Class B  Certificate
shall be made (other  than the  transfer  of the Class  1-A-PO and Class  2-A-PO
Certificates  to an  affiliate  of the Seller on the  Closing  Date)  unless the
Trustee shall have received (i) a  representation  letter from the transferee in
the form of Exhibit  J-1 hereto,  in the case of a Class  1-A-PO,  Class  1-B-4,
Class 1-B-5 or Class 1-B-6  Certificate and Exhibit K-1 hereto, in the case of a
Class 1-B-1, Class 1-B-2 or Class 1-B-3  Certificate,  or in the form of Exhibit
J-2 hereto,  in the case of a Class  2-A-PO,  Class 2-B-4,  Class 2-B-5 or Class
2-B-6  Certificate and Exhibit K-2 hereto,  in the case of a Class 2-B-1,  Class
2-B-2 or Class 2-B-3 Certificates, 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, 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
B Certificates only, if such transferee is an insurance company,  (A) the source
of funds used to  purchase  the 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)),  (B) 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  and (C) the  purchase  and  holding of such Class B
Certificates  are covered by Sections I and III of PTE 95-60 or (ii) in the case
of any such Class  1-A-PO,  Class 2-A-PO 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  1-A-PO,  Class  2-A-PO  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 1-A-PO,  Class 2-A-PO 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
2-A-R or Class 2-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 acting on behalf of or 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 2-A-R or Class
2-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 2-A-R or
Class 2-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 2-A-R or Class  2-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 2-A-R or Class 2-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 2-A-R or Class 2-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 2-A-R or
Class 2-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 2-A-R or Class 2-A-LR  Certificate to any
Person who does not provide an affidavit  substantially  in the form attached as
Exhibit H hereto.

     The  affidavit  described in the  preceding  paragraph,  if not executed in
connection  with the  initial  issuance  of the  Class  2-A-R  or  Class  2-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 2-A-R and Class 2-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 2-A-R or Class 2-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  2-A-R or
Class 2-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  2-A-R or Class  2-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 the Class 2-A-R or Class 2-A-LR Certificate, and (ii)
the Master Servicer agrees to furnish to the Internal Revenue Service and to any
transferor of the Class 2-A-R or Class 2-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 2-A-R or Class 2-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.

     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 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.  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 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  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,  (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 Class 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  or  (iv)  upon  the
occurrence of the events specified in Section 4.07(g),  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.

     Section 6.01. Liability of the Seller and the Master Servicer.

     The  Seller  and the Master  Servicer  shall  each be liable in  accordance
herewith  only to the  extent of the  obligations  specifically  imposed by this
Agreement and undertaken hereunder by the Seller and the Master Servicer.

     Section 6.02. Merger or Consolidation of the Seller or the Master Servicer.

     Subject to the following paragraph, the Seller and the Master Servicer each
will keep in full effect its  existence,  rights and franchises as a corporation

     The Seller or the Master  Servicer  may be merged or  consolidated  with or
into any  Person,  or  transfer  all or  substantially  all of its assets to any
Person,  in which case any Person  resulting from any merger or consolidation to
which the Seller or Master Servicer shall be a party,  or any Person  succeeding
to the business of the Seller or Master Servicer,  shall be the successor of the
Seller or Master  Servicer  hereunder,  without the  execution  or filing of any
paper or any  further  act on the part of any of the  parties  hereto,  anything
herein to the contrary notwithstanding;  provided, however, that, in the case of
the Master  Servicer,  any such successor or resulting Person shall be qualified
to service mortgage loans for FNMA or FHLMC.

     Section 6.03.  Limitation on Liability of the Seller,  the Master  Servicer
and Others.

     Neither the Seller nor the Master Servicer nor any subcontractor nor any of
the partners,  directors,  officers, employees or agents of any of them shall be
under any liability to the Trust Estate or the  Certificateholders  and all such
Persons shall be held harmless for any action taken or for  refraining  from the
taking of any action in good faith pursuant to this Agreement,  or for errors in
judgment;  provided,  however,  that this  provision  shall not protect any such
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,

Certificates,  other than any loss,  liability or expense  incurred by reason of
willful misfeasance,  bad faith or gross 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  Accounts,  and such
amounts shall,  on the following  Distribution  Date or  Distribution  Dates, be
allocated  between the Group 1 Certificates and Group 2 Certificates,  pro rata,
and within each Group in reduction of  distributions  on the Class A and Class B
Certificates  of such Group in the same manner as Realized  Losses to such Group
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 applicable  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
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.

DEFAULT

     Section 7.01. Events of Default.

     In case  one or more of the  following  Events  of  Default  by the  Master
Servicer shall occur and be continuing, that is to say:

          (i) any failure by the Master  Servicer  (a) to remit any funds to the
     Paying Agent as required by Section 4.03 or (b) to  distribute  or cause to
     be distributed to Certificateholders any payment required to be made by the
     Master  Servicer under the terms of this Agreement  which,  in either case,
     continues  unremedied  for a period of three  business  days after the date
     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
     trustee,  conservator,  receiver or liquidator or liquidating  committee in
     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 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 a 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 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,  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  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 a 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
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 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

          (iii) The Trustee  shall not be liable for any error of judgment  made
     in good  faith by any of its  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 request and 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  and the  manner of  obtaining
     consents and evidencing the authorization of the execution thereof shall be
     subject to such reasonable regulations as the Trustee may prescribe;

          (ii) The Trustee may consult with counsel,  and any written  advice of
     such  counsel  or 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 advice or
     Opinion of Counsel;

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

          (iv) Subject to Section 7.04,  the Trustee  shall not be  accountable,
     shall  have no  liability  and  makes no  representation  as to any acts or
     omissions  hereunder of the Master  Servicer until such time as the Trustee
     may be required  to act as Master  Servicer  pursuant  to Section  7.05 and
     thereupon  only for the acts or omissions  of Trustee as  successor  Master
     Servicer; and

          (v) The Trustee may execute any of the trusts or powers  hereunder  or
     perform any duties  hereunder  either  directly or by or through  agents or
     attorneys.

     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 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 a
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, and may transact banking and/or trust
business with the Seller, the Master Servicer or their Affiliates.

     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 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.

     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.

     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,  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 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 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 1-A-1,  Class 1-A-PO,  Class 1-B-1,
Class 1-B-2,  Class 1-B-3,  Class 1-B-4,  Class 1-B-5, Class 1-B-6, Class 2-A-1,
Class 2-A-2,  Class 2-A-3,  Class 2-A-4,  Class 2-A-5, Class 2-A-6, Class 2-A-7,
Class 2-A-8,  Class 2-A-9,  Class  2-A-10,  Class 2-A-11,  Class  2-A-12,  Class
2-A-PO,  Class 2-A-R,  Class 2-B-1, Class 2-B-2, Class 2-B-3, Class 2-B-4, Class
2-B-5 and Class 2-B-6  Certificates  and the interests in the  Lower-Tier  REMIC
represented  by the Class 1-A-L1,  Class  1-A-LPO,  Class 1-B-LI,  Class 1-B-L2,
Class 1-B-L3,  Class 1-B-L4,  Class 1-B-L5,  Class 1-B-L6,  Class 2-A-L1,  Class
2-A-L3,  Class 2-A-L5,  Class 2-A-L6, Class 2-A-L7, Class 2-A-L9, Class 2-A-L11,
Class 2-A-LPO,  Class 2-A-LUR,  Class 2-B-L1,  Class 2-B-L2, Class 2-B-L3, Class
2-B-L4,   Class  2-B-L5  and  Class  2-B-L6   Interests  and  the  Class  2-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 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   2-A-R   and   Class   2-A-LR
Certificateholders  for  such  purpose  (or if  the  Master  Servicer  is not so
permitted, the Holders of the Class 2-A-R and Class 2-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's sole duties with respect to the Upper-Tier
REMIC and Lower Tier REMIC are to sign the tax returns referred to in clause (i)
of the second preceding  sentence and to comply with written directions from the
Master Servicer or the Trustee.

     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 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  Upper-Tier  REMIC and  Lower-Tier  REMIC as
described  above.  In the event that the Trustee  prepares  any of the  federal,
state and local tax  returns  of the  Upper-Tier  REMIC or  Lower-Tier  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
or 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.

certain notices as hereinafter set forth and the tax reporting obligations under
Sections 4.05 and 8.14 hereof) shall  terminate upon the last action required to
be taken by the Trustee on the Final  Distribution Date pursuant to this Article
IX following the earlier of (i) the purchase by the Seller of all Mortgage Loans
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
close of business on the third  Business Day next  preceding the date upon which
notice of any such  termination is furnished to  Certificateholders  pursuant to
the third paragraph of this Section 9.01),  plus any accrued and unpaid interest
through the last day of the month  preceding  the month of such  purchase at the
applicable Mortgage Interest Rate less any Fixed Retained Yield on each Mortgage
Loan  (including  any REO  Mortgage  Loan) and (ii) the final  payment  or other
liquidation  (or any advance with  respect  thereto) of the last  Mortgage  Loan
remaining in the Trust Estate  (including  for this purpose the discharge of any
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 sum of the Pool I and  Pool II  Scheduled  Principal
Balances of the Mortgage Loans as of the Final Distribution Date being less than
the amount set forth in Section 11.22. 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 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  appropriate
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   from  the   appropriate   Certificate   Account  to
Certificateholders  on the  Final  Distribution  Date  in  proportion  to  their
respective  Percentage  Interests  an amount  equal to (i) as to the  Classes of
Class 1-A and Class 2-A Certificates,  the respective Principal Balance together
with any  related  Class 1-A  Unpaid  Interest  Shortfall  and Class 2-A  Unpaid
Interest Shortfall, respectively, and one month's interest in an amount equal to
the respective  Class 1-A Interest Accrual Amount and Class 2-A Interest Accrual
Amount,  (ii) as to the  Classes  of Class 1-B and Class 2-B  Certificates,  the
respective Principal Balance together with any related Class 1-B Unpaid Interest
Shortfall and Class 2-B Unpaid Interest Shortfall, respectively, and one month's
interest in an amount equal to the  respective  Group 1 Interest  Accrual Amount
and Group 2 Interest  Accrual  Amount and (iii) as to the Class  2-A-R and Class
2-A-LR  Certificates,  the  amounts,  if any,  which  remain on  deposit  in the
Upper-Tier Certificate Account and the Certificate Accounts, 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 or Classes 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.

     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  Accounts  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.

MISCELLANEOUS PROVISIONS

     Section 10.01. Amendment.

     (a) This  Agreement or any Custodial  Agreement may be amended from time to
time by the Seller, the Master Servicer and the Trustee,  without the consent of
any of the  Certificateholders,  (i) to cure any  ambiguity or mistake,  (ii) to
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
qualification  of the Trust Estate as two separate  REMICs at all times that any
Certificates  are outstanding or to avoid or minimize the risk of the imposition
of any federal tax on the Trust Estate,  the Upper-Tier  REMIC or the Lower-Tier
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
Certificate  Account provided that (a) such change shall not, as evidenced by an
Opinion of Counsel,  adversely  affect in any material  respect the interests of
any  Certificateholder  and (b) such  change  shall  not  adversely  affect  the
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  and the Holders of
Certificates  evidencing in the aggregate not less than 66-2/3% of the aggregate
Voting Interests of each Class of Certificates  affected thereby for the purpose
of adding any provisions to or changing in any manner or eliminating  any of the
provisions of this Agreement or such Custodial  Agreement or of modifying in any
manner  the rights of the  Holders  of  Certificates  of such  Class;  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 of such
Certificate,  (ii) adversely  affect in any material respect the interest of the
Holders of  Certificates  of any Class in a manner  other than as  described  in
clause (i) hereof without the consent of Holders of  Certificates  of such Class
evidencing, as to such Class, Voting Interests aggregating not less than 66-2/3%
or (iii)  reduce  the  aforesaid  percentage  of  Certificates  of any Class the
Holders of which are  required  to consent to any such  amendment,  without  the
consent of the Holders of all Certificates of such Class 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:

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

     (ii) 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.

     A copy of any  amendment  to Schedule I pursuant to this  Section  10.01(b)
shall be promptly forwarded to the Trustee.

     Section 10.02. Recordation of Agreement.

     This  Agreement (or an abstract  hereof,  if  acceptable to the  applicable
recording  office) is subject to recordation in all  appropriate  public offices
for real property records in all the towns or other comparable  jurisdictions in
which any or all of the  Mortgaged  Properties  are  situated,  and in any other
appropriate  public 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
an  original,  and  such  counterparts  shall  constitute  but one and the  same
instrument.

     Section 10.03. Limitation on Rights of Certificateholders.

     The death or  incapacity  of any  Certificateholder  shall not  operate  to
terminate   this   Agreement   or   the   Trust   Estate,   nor   entitle   such
Certificateholder's  legal  representatives  or heirs to claim an  accounting or
take any action or  proceeding in any court for a partition or winding up of the
Trust Estate,  nor otherwise  affect the rights,  obligations and liabilities of
the parties hereto or any of them.

     Except as otherwise expressly provided herein, no Certificateholder, solely
by virtue of its status as a Certificateholder,  shall have any right to vote or
in any manner  otherwise  control  the  operation  and  management  of the Trust
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
to the Trustee a written notice of default and of the  continuance  thereof,  as
hereinbefore  provided,  and unless also the Holders of Certificates  evidencing
not less than 25% of the Voting Interest  represented by all Certificates  shall
have made written  request upon the Trustee to  institute  such action,  suit or
proceeding  in its own name as Trustee  hereunder  and shall have offered to the
Trustee such reasonable  indemnity as it may require against the cost,  expenses
and liabilities to be incurred therein or thereby,  and the Trustee, for 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
one or more Holders of Certificates  shall have any right in any manner whatever
by virtue or by availing of any provision of this  Agreement to affect,  disturb
or prejudice the rights of the Holders of any other of such Certificates,  or to
obtain or seek to obtain  priority  over or preference to any other such Holder,
or to enforce  any right  under  this  Agreement,  except in the  manner  herein
provided and for the benefit of all  Certificateholders.  For the protection and
enforcement of the provisions of this Section, each and every  Certificateholder
and the Trustee  shall be entitled to such relief as can be given  either at law
or in equity.

given,  whether or not the addressee  receives such notice,  provided,  however,
that any  demand,  notice or  communication  to or upon the  Seller,  the Master
Servicer, or the Trustee shall not be effective until received.

     For all purposes of this Agreement,  in the absence of actual  knowledge by
an officer of the Master  Servicer,  the Master  Servicer shall not be deemed to

     Section 10.06. Severability of Provisions.

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

remaining covenants, agreements, provisions or terms of this Agreement and shall

Agreement or of the Certificates or the rights of the Holders thereof.

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

Day immediately  following (the  "Distribution  Date"),  commencing on the first

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 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

created pursuant to a Pooling and Servicing  Agreement dated as of July 29, 1998
(the   "Agreement")   among  the  Seller,   Norwest  Bank  Minnesota,   National
Association, as master servicer (the "Master Servicer") and First Union National

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 1-A  Certificates  and each Class of Class 1-B  Certificates
bearing a lower numerical  designation as specified in the Agreement,  any Class

name and address shall appear on the Certificate  Register.  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

is 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 will also require (i) a representation letter, in the form
as described in the  Agreement,  stating either (a) 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 (b) subject to certain  conditions  described  in the
Agreement,  that the source of funds used to  purchase  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  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  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.

the Trustee, by manual signature,  this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

the  Agreement.  This  Certificate  is issued under and is subject to the terms,

     THIS CERTIFIES THAT  ___________________________ is the registered owner of
the Percentage  Interest evidenced by this Certificate in monthly  distributions
to the Holders of the Class 2-A-9  Certificates  with  respect to a Trust Estate
consisting of a pool of fixed  interest rate,  conventional,  monthly pay, fully
amortizing,  first lien, one- to four-family  residential  mortgage loans, other
than the Fixed  Retained  Yield,  if any,  with respect  thereto,  and which may
include loans secured by shares issued by cooperative housing  corporations (the
"Pool II  Mortgage  Loans"),  formed by  Norwest  Asset  Securities  Corporation
(hereinafter called the "Seller", which term includes any successor entity under
the  Agreement  referred to below).  The Trust Estate was created  pursuant to a
Pooling and  Servicing  Agreement  dated as of July 29,  1998 (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 the  Class  2-A
Distribution Amount for the Class 2-A-9 Certificates  required to be distributed
to Holders of the Class 2-A-9 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 Classes of Class 2-A Certificates
may not commence on the first  Distribution Date specified above.  Distributions
of principal will be allocated  among the Classes of Class 2-A  Certificates  in
accordance with the provisions of the Agreement.  The  pass-through  rate on the
Class 2-A-9 Certificates applicable to each Distribution Date will be a floating
rate  of  interest  determined  as  provided  herein  and  as  specified  in the
Agreement.  Interest  on this  Certificate  will  accrue  with  respect  to each
Distribution  Date  during  the period  commencing  on the 25th day of the month
preceding  the month in which such  Distribution  Date  occurs and ending on the
24th day of the month in which  such  Distribution  Date  occurs  (each a "LIBOR
Based Interest Accrual  Period").  The pass-through rate applicable with respect
to the initial LIBOR Based  Interest  Accrual Period will be 6.15625% per annum.
Thereafter,  with  respect to each LIBOR  Based  Interest  Accrual  Period,  the
pass-through  will be a per annum  rate  equal to the  lesser of (i) 0.50%  plus
LIBOR,  as determined on the second  business day preceding the  commencement of
such LIBOR Based Interest Accrual Period, and (ii) 8.50%. The amount of interest
which accrues on this  Certificate  in any LIBOR Based  Interest  Accrual Period
will be subject to reduction with respect to any Group 2 Non-Supported  Interest
Shortfall and the interest  portion of certain  Realized Losses allocated to the
Class 2-A-9 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, 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.

     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  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.

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

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.

representation letter, in the form as described in the Agreement, stating either
(a) 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 (b)  subject to certain
conditions described in the Agreement, that the source of funds used to purchase
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  respect to certain
matters and (b) such other  documentation  as the Seller or the Master  Servicer

is 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 will also require (i) a representation letter, in the form
as described in the  Agreement,  stating either (a) 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 (b) subject to certain  conditions  described  in the
Agreement,  that the source of funds used to  purchase  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  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  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.

                [Form of Reverse of Series 1998-19 Certificates]

                      NORWEST ASSET SECURITIES CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATES
                                 SERIES 1998-19

     This Certificate is one of a duly authorized  issue of Certificates  issued
in several  Classes  designated  as Mortgage  Pass-Through  Certificates  of the
Series specified hereon (herein  collectively  called the  "Certificates").  The
Certificates  will  consist of two groups  (the "Group 1  Certificates"  and the
"Group 2 Certificates" respectively, and each a "Group").

     The Group 1 Certificates  and Group 2 Certificates  are limited in right of
payment to certain  collections  and  recoveries  respecting the Pool I Mortgage
Loans and Pool II Mortgage Loans,  respectively,  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 of the related Group.

     As provided in the Agreement,  withdrawals from the applicable  Certificate
Account created for the benefit of  Certificateholders  of the related Group 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 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 new  Certificates of authorized  Denominations  evidencing
the  same  Class  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  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 sum of Pool I  Scheduled  Principal
Balance and the Pool II Schedule  Principal Balance of the Pool I Mortgage Loans
and Pool II Mortgage Loans, as of the Distribution  Date upon which the proceeds
of such  repurchase are  distributed  being less than 4.75 percent of the sum of
the Pool I Cut-Off  Date  Aggregate  Principal  Balance and Pool II Cut-Off Date
Aggregate Principal Balance.

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
File or any document  therein so released to be returned to the  Custodian  when
the need  therefor  by the  Master  Servicer  no longer  exists,  unless (i) the
Mortgage 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 the Pooling and Servicing  Agreement or (ii) the  Custodial  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
Custodian a  certificate  of a Servicing  Officer  certifying as to the name and
address  of the  Person  to which  such  Custodial  File or such  document  were
delivered  and the  purpose or purposes  of such  delivery.  In the event of the
liquidation of a Mortgage  Loan,  the Custodian  shall deliver such receipt with
respect thereto to the Master  Servicer upon deposit of the related  Liquidation
Proceeds in the  Certificate  Account to the extent  required by the Pooling and
Servicing Agreement.

     Section  2.6.  Assumption  Agreements.  In the  event  that any  assumption
agreement or substitution of liability agreement is entered into with respect to
any Mortgage  Loan subject to this  Agreement in  accordance  with the terms and
provisions of the Pooling and Servicing  Agreement,  the Master  Servicer  shall
notify the Custodian  that such  assumption or  substitution  agreement has been
completed by  forwarding  to the  Custodian  the original of such  assumption or
substitution agreement,  which copy shall be added to the related Custodial File
and, for all purposes,  shall be considered a part of such Custodial File to the
same extent as all other documents and instruments constituting parts thereof.

                                   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.

     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 authority,  has a combined capital and surplus
of at least  $10,000,000 and is qualified to do business in the  jurisdiction in
which it will hold any Custodian File.

                                   ARTICLE IV

                            Miscellaneous Provisions

     Section 4.1. Notices. All notices, requests, consents and demands and other
communications required under this Agreement or pursuant to any other instrument
or  document  delivered  hereunder  shall be in writing  and,  unless  otherwise
specifically provided, may be delivered personally,  by telegram or telex, or by
registered or certified mail, postage prepaid,  return receipt requested, at the
addresses  specified  on  the  signature  page  hereof  (unless  changed  by the
particular  party whose address is stated herein by similar  notice in writing),
in which case the notice will be deemed delivered when received.

     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
accordance with and governed by the laws of the State of New York.

     Section  4.4.  Recordation  of  Agreement.   To  the  extent  permitted  by
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
an  original,  and  such  counterparts  shall  constitute  but one and the  same
instrument.

     Section  4.5.  Severability  of  Provisions.  If  any  one or  more  of the
covenants,  agreements,  provisions or terms of this Agreement  shall be for any
reason whatsoever held invalid, then such covenants,  agreements,  provisions or
terms  shall be  deemed  severable  from the  remaining  covenants,  agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability  of the other provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

promulgated  thereunder  and that such  transfer  of the  Class  [2-A-R][2-A-LR]
Certificate  will not be  disregarded  for federal  income tax  purposes.  "U.S.

     plan, as defined in Section 3(32) of ERISA subject to any federal, state or

     "Benefit  Plan Opinion"  satisfactory  to the Seller and the Trustee of the

     regarded  as  "plan  assets"  and  subject  to the  prohibited  transaction

     Board of  Governors  of the Federal  Reserve  System  ("FRB"),  the Federal

     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,

     [1-A-PO][1-B-4][1-B-5][1-B-6] Certificates is in compliance therewith.

     Section 3. Transfer of Class [1-A-PO][1-B-4][1-B-5][1-B-6] Certificates.

     Certificates  are  registered  under  the Act and  applicable  state law or
     unless an exemption from  registration is available.  The Purchaser further
     understands that neither the Seller, the Master Servicer nor the Trustee is
     under any  obligation  to register the Class  [1-A-PO][1-B-4][1-B-5][1-B-6]
     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 the  Seller  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 the Seller may, if such
     transfer is made within  three years from the later of (a) the Closing Date
     or (b) the last date on which the  Seller 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
     Act and state  securities  laws,  which  Opinion of Counsel shall not be an
     expense  of the  Trustee,  the  Master  Servicer  or the  Seller.  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 the Seller  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  [1-A-PO][1-B-4][1-B-5][1-B-6]  Certificate
     shall be made  unless the  transferee  provides  the Seller and the Trustee
     with a Transferee's Letter, substantially in the form of this Agreement.

          (c)     The     Purchaser      acknowledges     that     its     Class
     [1-A-PO][1-B-4][1-B-5][1-B-6]  Certificates bear a legend setting forth the
     applicable restrictions on transfer.

     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 [Pool I] [Pool
II]  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
     [Pool I] [Pool II] 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  [Pool I]  [Pool  II]  Mortgage  Loan  the loan  number  and
     outstanding principal balance.

          (ii) Prior to the  Commencement  of Foreclosure in connection with any
     [Pool I] [Pool II] 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 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 [Pool I]
     [Pool II] 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 the Servicer (to
the extent that the Company as Master  Servicer is granted such authority in the
related Servicing  Agreement) 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 [Pool I] [Pool II] 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 the Servicer (to
the extent that the Company as Master  Servicer is granted such authority in the
related Servicing Agreement) 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 [Pool I] [Pool II]
Mortgage  Loan that is at least ninety days  delinquent  and each [Pool I] [Pool
II]  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 direct (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
[Pool I] [Pool II]  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 [Pool
I] [Pool II]  Mortgage  Loan has been  brought  current or if a  refinancing  or
prepayment  occurs  with  respect  to the  [Pool  I]  [Pool  II]  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 the 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 [Pool I] [Pool II] 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 be provided only
to the extent it (i) is not confidential in nature and (ii) is obtainable by the
related  Servicer  from  existing  reports,  certificates  or  statements  or is
otherwise 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 [Pool I] [Pool II]  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 [Pool I] [Pool
II] 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 [Pool I] [Pool II] 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 [Pool I] [Pool II]  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 [Pool I] [Pool II] Mortgage Loan upon the failure
of the  Purchaser to deposit any of the above  amounts  relating to the [Pool I]
[Pool II]  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 [Pool I] [Pool II]  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 [Pool I] [Pool  II]  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  if 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,  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 [Pool I] [Pool II]
Mortgage Loan is brought current by the mortgagor,  all amounts remaining in the
Collateral  Fund in  respect  of such [Pool I] [Pool II]  Mortgage  Loan  (after
adjustment  for  all  permitted   withdrawals  and  deposits  pursuant  to  this
subsection) shall be released to the Purchaser.

     (f) With  respect to any [Pool I] [Pool II]  Mortgage  Loan as to which the
Purchaser has made an Election to Delay Foreclosure,  the related Servicer shall
continue to service the [Pool I] [Pool II] 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  [Pool I] [Pool  II]
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 [Pool I] [Pool II] 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 of immediately
available  funds from the  Purchaser  to the  Company for deposit in the related
Certificate  Account;  or (ii)  the  related  Servicer  shall  proceed  with the
Commencement of Foreclosure.

     (g) Upon the occurrence of a liquidation with respect to any [Pool I] [Pool
II]  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  [Pool I] [Pool II]  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 [Pool I] [Pool II] 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 [Pool I] [Pool  II]  Mortgage  Loan and three  months
interest  on the [Pool I] [Pool II]  Mortgage  Loan at the  applicable  Mortgage
Interest  Rate. If and when any such [Pool I] [Pool II] Mortgage Loan is brought
current by the mortgagor,  all amounts in the Collateral Fund in respect of such
[Pool I] [Pool II] Mortgage Loan (after adjustment for all permitted withdrawals
and deposits  pursuant to this Agreement)  shall be released to the Purchaser if
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,  applicable law or the related mortgage note. The terms of
this  Agreement  will no longer apply to the servicing of any [Pool I] [Pool II]
Mortgage  Loan upon the failure of the  Purchaser  to deposit the above  amounts
relating to the [Pool I] [Pool II] Mortgage Loan within two Business Days of the
Election to Foreclose subject to Section 3.01.

     (c) With  respect to any [Pool I] [Pool II]  Mortgage  Loan as to which the
Purchaser has made an Election to Foreclose, the related Servicer shall continue
to service the [Pool I] [Pool II] 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  Liquidations  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 [Pool I] [Pool II] 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 [Pool I] [Pool II]
Mortgage Loan has been brought current or if a refinancing or prepayment  occurs
with respect to the [Pool I] [Pool II] 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 [Pool I] [Pool
II] 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 [Pool I] [Pool II]  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  [Pool I] [Pool II]  Mortgage  Loan  shall be  released  to the
Purchaser.

     Section 2.04 Termination

     (a) With respect to all [Pool I] [Pool II] 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 [Pool I] [Pool II] Mortgage Loans in the related
pool as  determined by the Company) of the  aggregate  principal  balance of all
[Pool I] [Pool II] 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 [Pool I] [Pool II] 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) upon 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 [Pool I] [Pool II] 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  [Pool I] [Pool
II] Mortgage  Loan shall  terminate if the  Purchaser  fails to make any deposit
required  pursuant to Section  2.02(d) or 2.03(b) or if the  Purchaser  fails to
make any other deposit to the Collateral Fund pursuant to this Agreement.


                                   ARTICLE III

                       COLLATERAL FUND; SECURITY INTEREST

     Section 3.01. Collateral Fund

     Upon  receipt  from the  Purchaser  of the  initial  amount  required to be
deposited  in the  Collateral  Fund  pursuant to Article  II, the Company  shall
establish and maintain with Bankers Trust Company as a segregated account on its
books and records an account (the  "Collateral  Fund"),  entitled  "Norwest Bank
Minnesota,  National  Association,  as  Master  Servicer,  for  the  benefit  of
registered holders of Norwest Asset Securities Corporation Mortgage Pass-Through
Certificates, Series 1998-19. Amounts held in the Collateral Fund shall continue
to be the  property of the  Purchaser,  subject to the first  priority  security
interest  granted  hereunder  for the 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 [Pool I]
[Pool II]  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 or cause to be  distributed  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").

     The  Purchaser  acknowledges  the lien on and 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 [Pool I] [Pool II] 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 [Pool I] [Pool II] Mortgage
Loans to which such insufficiencies relate, without the necessity of any further
notice or demand on the part of the Company.
