ITEM 5. Other Events

               On October 28, 1999,  Norwest  Asset  Securities  Corporation,  a
Delaware   corporation   (the   "Registrant"),    sold   Mortgage   Pass-Through
Certificates,  Series 1999-24, Class A-1, Class A-2, Class A-3, Class A-4, Class
A-5, Class A-6, Class A-7, Class A-8, Class A-9, Class A-10,  Class A-11,  Class
A-R,   Class  A-LR,   Class  B-1,   Class  B-2  and  Class  B-3  (the   "Offered
Certificates"),    having   an   aggregate   original   principal   balance   of
$392,961,100.00.  The Offered Certificates were issued pursuant to a Pooling and
Servicing Agreement, dated as of October 28, 1999, 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  1999-24,  Class A-PO  Certificates,  having an  aggregate
initial principal  balance of $4,569,363.42,  and Class B-4, Class B-5 and Class
B-6 Certificates, having an aggregate initial principal balance of $2,802,859.21
(the  "Private  Class  B  Certificates"   and,  together  with  the  Class  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  98.16% 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 the 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
A-PO and Private  Class B  Certificates.  Distributions  on the Private  Class B
Certificates are  subordinated to distributions on the Offered  Certificates and
the Class 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 A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class
A-6, Class A-7, Class A-8, Class A-9, Class A-10,  Class A-11, Class A-PO, Class
B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates  will
be treated as "regular  interests" in the Upper-Tier REMIC and the Class A-R and
Class  A-LR  Certificates  will be treated as the  "residual  interests"  in the
Upper-Tier REMIC and Lower-Tier REMIC, respectively.

                                   DEFINITIONS

            SECTION 1.01      DEFINITIONS.

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

            Accepted  Master  Servicing  Practices:  Accepted  Master  Servicing

                      ORIGINAL ISSUANCE OF THE CERTIFICATES

            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 and
(d) proceeds of all the foregoing.

            In connection with such assignment,  the Seller shall,  with respect
to each Mortgage Loan,  deliver,  or cause to be delivered,  to the Trustee,  as
initial  Custodian,  on or before the Closing Date, an Owner Mortgage Loan File.
If any  Mortgage  or an  assignment  of a Mortgage  to the  Trustee or any prior
assignment is in the process of being  recorded on the Closing Date,  the Seller
shall deliver a copy thereof,  certified by Norwest  Mortgage or the  applicable
Norwest  Mortgage  Correspondent  to be a true and complete copy of the document
sent for recording, and the Seller shall use its best efforts to cause each such
original  recorded  document or  certified  copy  thereof to be delivered to the
Trustee promptly  following its recordation,  but in no event later than one (1)
year  following  the Closing Date. If any Mortgage has been recorded in the name
of Mortgage Electronic  Registration  System, Inc. ("MERS") or its designee,  no
assignment  of Mortgage in favor of the Trustee  will be required to be prepared
or delivered  and  instead,  the Master  Servicer  shall take all actions as are
necessary  to cause  the Trust  Estate  to be shown as the owner of the  related
Mortgage  Loan on the records of MERS for the purpose of the system of recording
transfers of beneficial  ownership of mortgages  maintained by MERS.  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  (except  with  respect to any
Mortgage  recorded  in the name of MERS) 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  (unless the related Mortgage has been registered in
the name of MERS or its designee) 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 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 (or, in the case of a Mortgage Loan registered in the name of MERS or
its designee,  the Master  Servicer  shall take all necessary  action to reflect
such assignment on the records of MERS), 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:

               (i)  The information set forth in the Mortgage  Loan Schedule was
      true and correct in all material  respects at the date or dates respecting
      which such  information  is furnished  as  specified in the Mortgage  Loan
      Schedule;

               (ii)   Immediately   prior  to  the   transfer   and   assignment
      contemplated  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

      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 to, and  delivered  to the Trustee or to the
      Custodian  with,  any  Mortgage  establishes  in the  Seller  a valid  and
      subsisting first lien on the property described therein and the Seller has
      full right to sell and assign the same to the Trustee;

      Mortgage 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
      Mortgage Loan proceeds,  whichever is later,  to the day which precedes by
      thirty days the first Due Date under the related Mortgage Note;

               (vi)  The  Mortgaged   Property  is  undamaged  by  water,  fire,

      tornado or similar  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

      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  Loans secured by  residential  long-term  leases,  the Mortgaged
      Property  consists  of a fee simple  estate in real  property;  all of the
      improvements  which  are  included  for the  purpose  of  determining  the

      obtained from the appropriate authorities;

               (xi)  All  payments  required  to be  made  up to  the  Due  Date

               (xii)  The  Mortgage  Note,   the  related   Mortgage  and  other
      agreements executed in connection  therewith are genuine,  and each is the

      bankruptcy, insolvency, reorganization or other similar laws affecting the
      enforcement  of  creditors'   rights   generally  and  by  general  equity
      principles  (regardless  of whether such  enforcement  is  considered in a
      proceeding  in  equity  or at  law);  and,  to the  best  of the  Seller's

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

               (xvi) The  Mortgaged  Property  securing  each  Mortgage  Loan is
      insured by an insurer acceptable to FNMA or FHLMC against loss by fire and
      such  hazards  as  are  covered   under  a  standard   extended   coverage
      endorsement, in an amount which is not less than the lesser of 100% of the
      insurable value of the Mortgaged  Property and the  outstanding  principal
      balance of the Mortgage Loan, but in no event less than the minimum amount
      necessary to fully compensate for any damage or loss on a replacement cost
      basis;  if the Mortgaged  Property is a  condominium  unit, it is included
      under the coverage  afforded by a blanket policy for the project;  if upon
      origination  of the  Mortgage  Loan,  the  improvements  on the  Mortgaged
      Property were in an area identified in the Federal Register by the Federal
      Emergency  Management  Agency as having  special  flood  hazards,  a flood
      insurance policy meeting the requirements of the current guidelines of the
      Federal Insurance  Administration is in effect with a generally acceptable
      insurance carrier,  in an amount  representing  coverage not less than the
      least of (A) the outstanding  principal  balance of the Mortgage Loan, (B)
      the full  insurable  value of the  Mortgaged  Property and (C) the maximum
      amount of insurance which was available under the 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 360 months;

               (xx) Each Mortgage contains customary and enforceable  provisions
      such as to render the rights and remedies of the holder  thereof  adequate
      for the realization  against the Mortgaged Property of the benefits of the
      security,  including  realization by judicial  foreclosure (subject to any
      limitation  arising from any  bankruptcy,  insolvency or other law for the
      relief of debtors), and there is no homestead or other exemption available
      to the Mortgagor which would interfere with such right of foreclosure;

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

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

               (xxiii) The Mortgage  Loan is a "qualified  mortgage"  within the
      meaning of Section 860G(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  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 A-R and Class A-LR  Certificates) and the Classes of Class
B Certificates  as classes of "regular  interests" and the Class 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 A-L1 Interest,  Class A-L4 Interest,  Class
A-L9 Interest,  Class A-LPO Interest, Class A-LUR Interest, Class B-L1 Interest,
Class B-L2  Interest,  Class B-L3  Interest,  Class  B-L4  Interest,  Class B-L5
Interest and Class B-L6 Interest as classes of "regular interests" and the Class
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.

                                   ARTICLE III

                ADMINISTRATION OF THE TRUST ESTATE: SERVICING
                              OF THE MORTGAGE LOANS

            SECTION 3.01      CERTIFICATE ACCOUNT.

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

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

               (i)  Periodic Advances pursuant  to Section  3.03(a)  made by the
      Master Servicer or the Trustee,  if any and 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 the Certificate
Account to be invested in Eligible  Investments.  No such  Eligible  Investments
will be sold or  disposed  of at a gain  prior to  maturity  unless  the  Master
Servicer has received an Opinion of Counsel or other evidence satisfactory to it
that such sale or  disposition  will not cause the Trust Estate to be subject to
Prohibited Transactions Tax, otherwise subject the Trust Estate to tax, or cause
either of the Upper-Tier  REMIC or the Lower-Tier  REMIC to fail to qualify as a
REMIC while any  Certificates  are  outstanding.  Any amounts  deposited  in the
Certificate  Account  prior to the  Distribution  Date shall be invested for the
account  of the Master  Servicer  and any  investment  income  thereon  shall be
additional  compensation to the Master Servicer for services rendered under this
Agreement.  The amount of any losses incurred in respect of any such investments
shall be deposited in the Certificate  Account by the Master Servicer out of its
own funds immediately as realized.

            (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
                              ACCOUNT.

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

               (i) to reimburse the Master Servicer, the Trustee or any Servicer
      for 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, ny 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 the Certificate Account;

               (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  the   Certificate   Account  any  amount
      deposited  in  the  Certificate  Account   that  was  not  required  to be
      deposited therein;

               (xi) to clear  and  terminate  the  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 Certificate Account.

            SECTION 3.03      ADVANCES BY MASTER SERVICER AND TRUSTEE.

            (a)   In  the  event an Other  Servicer  fails to make any  required
Periodic  Advances of principal  and interest on a Mortgage  Loan as required by
the related Other Servicing  Agreement prior to the Distribution  Date occurring
in the month during  which such  Periodic  Advance is due,  the Master  Servicer
shall make Periodic Advances to the extent provided hereby. In the event Norwest
Mortgage fails to make any required  Periodic Advances of principal and interest
on a Mortgage Loan as required by the Norwest  Servicing  Agreement prior to the
Distribution  Date occurring in the month during which such Periodic  Advance is
due,  the  Trustee  shall,  to the extent  required by Section  8.15,  make such
Periodic  Advance to the extent provided  hereby,  provided that the Trustee has
previously  received the  certificate  of the Master  Servicer  described in the
following  sentence.  The Master  Servicer  shall  certify to the  Trustee  with
respect  to any such  Distribution  Date (i) the  amount  of  Periodic  Advances
required of Norwest  Mortgage or such Other  Servicer,  as the case may be, (ii)
the amount actually  advanced 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 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 Certificate  Account for any Periodic  Advance made by it
under Section 3.03(a) to the extent described in Section 3.02(a)(i) and (a)(ii).
The Master Servicer and the Trustee shall be entitled to be reimbursed  pursuant
to Section  3.02(a)(v)  for any advance by it pursuant to Section  3.03(b).  The
Master  Servicer  shall  diligently  pursue  restoration  of such  amount to the
Certificate Account from the related Servicer. The Master Servicer shall, to the
extent it has not already  done so, upon the  request of the  Trustee,  withdraw
from the  Certificate  Account and remit to the Trustee any amounts to which the
Trustee is entitled as reimbursement  pursuant to Section 3.02 (a)(i),  (ii) and
(v).

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

            SECTION 3.04      TRUSTEE TO COOPERATE; RELEASE OF OWNER MORTGAGE
                              LOAN FILES.

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

            From  time  to  time  and  as  appropriate   for  the  servicing  or
foreclosure of any Mortgage Loan, including but not limited to, collection under
any insurance policies, or to effect a partial release of any Mortgaged Property
from the lien of the Mortgage,  the Servicer of such Mortgage Loan shall deliver
to the Master Servicer a Request for Release. Upon the Master Servicer's receipt
of any such Request for Release, the Master Servicer shall promptly forward such
request to the Trustee and the Trustee shall, within five Business Days, release
the related Owner Mortgage Loan File to the Master Servicer or such Servicer, as
requested by the Master  Servicer.  Any such Request for Release shall  obligate
the Master  Servicer  or such  Servicer,  as the case may be, to return each and
every  document  previously  requested  from the Owner Mortgage Loan File to the
Trustee by the twenty-first  day following the release  thereof,  unless (i) the
Mortgage Loan has been liquidated and the Liquidation  Proceeds  relating to the
Mortgage Loan have been deposited in the  Certificate  Account or (ii) the Owner
Mortgage Loan File or such document has been  delivered to an attorney,  or to a
public  trustee or other  public  official as required by law,  for  purposes of
initiating or pursuing legal action or other  proceedings for the foreclosure of
the  Mortgaged  Property  either  judicially or  non-judicially,  and the Master
Servicer has  delivered to the Trustee a certificate  of the Master  Servicer or
such Servicer  certifying as to the name and address of the Person to which such
Owner  Mortgage  Loan File or such  document  was  delivered  and the purpose or
purposes of such  delivery.  Upon  receipt of an  Officer's  Certificate  of the
Master Servicer or such Servicer  stating that such Mortgage Loan was liquidated
and  that all  amounts  received  or to be  received  in  connection  with  such
liquidation which are required to be deposited into the Certificate Account have
been so deposited,  or that such Mortgage Loan has become an REO Mortgage  Loan,
the Request for Release shall be released by the Trustee to the Master  Servicer
or such Servicer, as appropriate.

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

            (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 a REO Mortgage Loan, the Trustee shall, at the written
request of the Master Servicer and upon being supported with  appropriate  forms
therefor, within five Business Days of the deposit by the Master Servicer of the
proceeds of such sale or auction into the Certificate Account,  release or cause
to be released to the entity identified by the Master Servicer the related Owner
Mortgage Loan File and Servicer Mortgage Loan File and shall execute and deliver
such instruments of transfer or assignment,  in each case without  recourse,  as
shall be  necessary to vest in the auction  purchaser  title to the REO Mortgage
Loan and the Trustee  shall have no further  responsibility  with regard to such
Owner  Mortgage Loan File or Servicer  Mortgage Loan File.  Neither the Trustee,
the Master  Servicer  nor any  Servicer,  acting on behalf of the Trust  Estate,
shall  provide  financing  from the  Trust  Estate  to any  purchaser  of an REO
Mortgage Loan.

            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  (including
the  obligation  to maintain an Errors and Omissions  Policy and Fidelity  Bond)
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 (i) 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 or (ii) any Mortgage  Loan in the Trust
Estate  which,  pursuant  to  paragraph  5(b)  of  the  Mortgage  Loan  Purchase
Agreement,  Norwest  Mortgage  requests the Seller to repurchase  and to sell to
Norwest Mortgage to facilitate the exercise of Norwest Mortgage's rights against
the  originator or a prior holder of such Mortgage  Loan. 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 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.

            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   Mortgage  Loans  and  will  contain
provisions  for the  deposit of cash by the holder that would be  available  for
distribution to  Certificateholders  if Liquidation  Proceeds are less than they
otherwise  may have been had the Servicer  acted in  accordance  with its normal
procedures.

            SECTION 3.09      TERMINATION AND SUBSTITUTION OF SERVICING
                              AGREEMENTS.

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

            The Master Servicer shall, on behalf of the Seller, make all filings
required  to be made by the  Seller  with  respect  to the Class A  Certificates
(other than the Class A-PO  Certificates) and the Class B-1, Class B-2 and Class
B-3 Certificates pursuant to the Securities Exchange Act of 1934, as amended.

allocated to the Classes of Class A Certificates  (other than the Class A-10 and
Class  A-PO  Certificates)  and any Class of Class B  Certificates  with a lower
numerical designation pro rata based on their Principal Balances.

            (ii) Distributions on the Uncertificated  Lower-Tier  Interests.  On
each Distribution Date, each Uncertificated  Lower-Tier Interest  shall  receive
distributions  in  respect  of  principal  in an amount  equal to the  amount of
principal  distributed  to its  respective  Corresponding  Upper-Tier  Class  or
Classes as provided  herein.  On each  Distribution  Date,  each  Uncertificated
Lower-Tier  Interest  shall receive  distributions  in respect of interest in an
amount equal to the Interest Accrual Amounts and 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  thereon. In the case of the Class
A-L1  Interest,  an amount  equal to the  Interest  Accrual  Amounts  and Unpaid
Interest Shortfalls of the Accrual Certificates which are added to the Principal
Balances  thereof,  will be added to the  Principal  Balance  of the Class  A-L1
Interest. 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 A-L1 Interest, Class
A-L4 Interest,  Class A-L9 Interest,  Class A-LUR Interest, Class B-L1 Interest,
Class B-L2  Interest,  Class B-L3  Interest,  Class  B-L4  Interest,  Class B-L5
Interest  and Class B-L6  Interest  shall be 7.000% per annum.  The Class  A-LPO
Interest is a  principal-only  interest and is not entitled to  distributions of
interest.  Any  Non-Supported  Interest  Shortfalls  will be  allocated  to each
Uncertificated  Lower-Tier Interest in the same relative proportions as interest
is allocated to such Uncertificated Lower-Tier Interest.

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

            On each  Distribution  Date occurring prior to the Cross-Over  Date,
the Class A Non-PO  Principal  Distribution  Amount will be allocated  among and
distributed  in  reduction of the  Principal  Balances of the Classes of Class A
Certificates  (other than the Principal Balance of the Class A-PO  Certificates)
in accordance with the following priorities:

            I.  On each  Distribution  Date  occurring  prior  to the  Accretion
      Termination Date for the Class A-5 Certificates,  the Accrual Distribution

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

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

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

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

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

                  (E) if the Current Class B-5 Fractional  Interest is less than
            the  Original  Class  B-5  Fractional  Interest  and the  Class  B-5
            Principal  Balance is greater than zero, the Class 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
entitled  to receive  distributions  of  principal  would  reduce the  Principal
Balances   of  the  Classes  of  Class  B   Certificates   entitled  to  receive
distributions of principal below zero,  first the Class B Prepayment  Percentage
of any  affected  Class  of Class B  Certificates  for  such  Distribution  Date
beginning with the affected Class with the lowest  numerical  Class  designation
and then,  if  necessary,  the Class B  Percentage  of such Class of the Class B
Certificates  for such  Distribution  Date shall be  reduced  to the  respective
percentages  necessary to bring the  Principal  Balance of such Class of Class B
Certificates  to  zero.  The  Class B  Prepayment  Percentages  and the  Class B
Percentages of the remaining  Classes of Class B Certificates will be recomputed
substituting  for  the  Subordinated   Prepayment  Percentage  and  Subordinated
Percentage in such  computations  the  difference  between (A) the  Subordinated
Prepayment  Percentage or Subordinated  Percentage,  as the case may be, and (B)
the percentages  determined in accordance with the preceding  sentence necessary
to bring the Principal  Balances of the affected Classes of Class B Certificates
to zero; provided, however, that if the Principal Balances of all the Classes of
Class B Certificates  eligible to receive  distributions  of principal  shall be
reduced to zero on such Distribution Date, the Class B Prepayment Percentage and
the Class B  Percentage  of the Class of Class B  Certificates  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 Subordinated  Prepayment  Percentage for such Distribution Date
minus the sum of the Class B  Prepayment  Percentages  of the Classes of Class B
Certificates  having  lower  numerical  Class  designations,  if  any,  and  the
remainder of the Subordinated  Percentage for such  Distribution  Date minus the
sum of the Class B  Percentages  of the Classes of Class B  Certificates  having
lower numerical Class designations, if any, respectively. Any entitlement of any
Class of Class B  Certificates  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 B Percentage or Class B Prepayment Percentage.

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

            (f)   On each  Distribution  Date other than the Final  Distribution
Date (if such Final  Distribution  Date is in connection  with a purchase of the
assets of the Trust Estate by the Seller),  the Paying Agent shall, on behalf of
the  Master  Servicer,  from  funds  remitted  to it  by  the  Master  Servicer,
distribute  to each  Certificateholder  of record  (other  than the  Class  A-LR
Certificateholder)  on the  preceding  Record  Date  (other  than as provided in
Section 9.01 respecting the final distribution to  Certificateholders  or in the
last  paragraph of this Section  4.01(f)  respecting the final  distribution  in
respect of any Class) 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 11.23, and has
so notified  the Master  Servicer or, if  applicable,  the Paying Agent at least
seven  Business  Days prior to the  Distribution  Date or, if such Holder  holds
Certificates  having,  in the aggregate,  a Denomination less than the requisite
minimum  Denomination  or if such Holder holds the Class A-R  Certificate or has
not so notified the Paying Agent,  by check mailed to such Holder at the address
of such Holder appearing in the Certificate Register, such Holder's share of the
Class A  Distribution  Amount with respect to each Class of Class A Certificates
and the Class B  Distribution  Amount with respect to each such Class of Class B
Certificates.

            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  A-10,  Class  A-R or Class  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 A-10  Certificates,  the Class A-10 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(f)  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  or  partnership  (unless,  in the case of a partnership,
Treasury  regulations are adopted that provide otherwise),  created or organized
in or under the laws of the United States,  any state thereof or the District of
Columbia,  including  an entity  treated as a  corporation  or  partnership  for
federal income tax purposes,  an estate whose income is subject to United States
federal  income tax  regardless of its source,  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)   With  respect to any Distribution  Date, the principal portion
of Realized  Losses (other than Debt Service  Reductions,  Excess Special Hazard
Losses,  Excess Fraud Losses and Excess Bankruptcy  Losses) will be allocated as
follows:

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

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

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

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

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

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

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

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

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

            (c)   Any   Realized  Losses   allocated  to  a  Class  of  Class  A
Certificates  or Class B  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 A-PO
Certificates,  based on the PO Fraction of such  Mortgage Loan and, with respect
to the Class A Certificates (other than the Class A-PO Certificates) and Class B
Certificates,  based on their  pro rata  share of the  Non-PO  Fraction  of such
Mortgage  Loan)  of  such  Recovery  up to the  amount  of  such  Realized  Loss
previously  allocated  to such  Class  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
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  Certificate  Account on or prior to
the Business Day  preceding  the  Distribution  Date  following  the  Applicable
Unscheduled  Principal  Receipt  Period  in which  the  Mortgage  Loan  became a
Liquidated Loan.

            (e)   The  interest portion of Excess Special Hazard Losses,  Excess
Fraud Losses and Excess  Bankruptcy  Losses  shall be allocated  between (i) the
Class A Certificates  and (ii) the Class B  Certificates,  pro rata based on the
Class A Interest  Accrual Amount and the Class B Interest Accrual Amount for the
related  Distribution  Date,  without  regard to any reduction  pursuant to this
sentence. Any such loss allocated to the Class A Certificates shall be allocated
among the  outstanding  Classes of Class A  Certificates  based on their Class A
Interest  Percentages.  Any such loss allocated to the Class B Certificates will
be allocated  among the  outstanding  Classes of Class B  Certificates  based on
their Class B Interest  Percentages.  In  addition,  after the Class B Principal
Balance has been reduced to zero, the interest portion of Realized Losses (other
than Excess  Special Hazard  Losses,  Excess Fraud Losses and Excess  Bankruptcy
Losses) will be allocated among the outstanding  Classes of Class A Certificates
based on their Class 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.

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

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

            SECTION 4.03      PAYING AGENT.

            (a)   The  Master  Servicer  hereby  appoints the Trustee as initial
Paying  Agent to make  distributions  to  Certificateholders  and to  forward to
Certificateholders the periodic statements and the annual statements required by
Section 4.04 as 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
Certificate Account or, to the extent required hereunder, from its own funds (i)
at or before  10:00 a.m.,  New York time,  on the Business  Day  preceding  each
Distribution Date, by wire transfer of immediately available funds, any Periodic
Advance for such  Distribution  Date,  pursuant  to Section  3.03 and (ii) at or

Distribution  Date,  by wire transfer of  immediately  available  funds,  (a) an
amount equal to the Pool Distribution  Amount, (b) Net Foreclosure  Profits,  if
any, with respect to such  Distribution  Date and (c) the amount of any recovery
in respect of a Realized Loss. The Master Servicer may cause the Paying Agent to
invest  the  funds  in the  Payment  Account.  Any such  investment  shall be in
Eligible  Investments,  which  shall  mature  not later  than the  Business  Day
preceding the related  Distribution  Date (unless the Eligible  Investments  are
obligations of the Trustee, in which case such Eligible Investments shall mature
not later than the  Distribution  Date),  and shall not be sold or  disposed  of
prior to maturity.  All income and gain realized from any such investment  shall
be for the benefit of the Master Servicer and shall be subject to its withdrawal
or order from time to time. The amount of any losses  incurred in respect of any
such  investments  shall be  deposited  in the  Payment  Account  by the  Master
Servicer  out of its own funds  immediately  as  realized.  The Paying Agent may
withdraw from the Payment  Account any amount  deposited in the Payment  Account
that was not required to be deposited  therein and may clear and  terminate  the
Payment Account pursuant to Section 9.01.

            SECTION 4.04      STATEMENTS TO CERTIFICATEHOLDERS; REPORT TO THE
                              TRUSTEE AND THE SELLER.

            Concurrently with each distribution pursuant to Section 4.01(f), the

            Within a  reasonable  period of time after the end of each  calendar

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.

                                THE CERTIFICATES

            SECTION 5.01      THE CERTIFICATES.

            (a)   The  Class A and Class B Certificates  shall be issued only in
minimum  Denominations  of a Single  Certificate and, except for the Class A-PO,
Class A-R and Class A-LR  Certificates,  integral  multiples of $1,000 in excess
thereof (except, if necessary, for one Certificate of each Class (other than the
Class A-10,  Class A-PO, Class A-R and Class A-LR  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 of such Class), and shall be substantially
in the respective forms set forth as Exhibits A-1, A-2, A-3, A-4, A-5, A-6, A-7,
A-8,  A-9,  A-10,  A-11,  A-PO,  A-R,  A-LR,  B-1, B-2, B-3, B-4, B-5, B-6 and C
(reverse side of Certificates)  hereto. On original issue the Certificates shall
be executed and delivered by the Trustee to or upon the order of the Seller upon
receipt by the Trustee or the  Custodian of the  documents  specified in Section
2.01.  The aggregate  principal  portion (or notional  amount)  evidenced by the
Class A and Class B  Certificates  shall be the sum of the amounts  specifically
set forth in the respective Certificates.  The Certificates shall be executed by
manual  or  facsimile  signature  on behalf of the  Trustee  by any  Responsible
Officer  thereof.  Certificates  bearing the manual or facsimile  signatures  of
individuals  who were at any time the proper  officers of the Trustee shall bind
the Trustee  notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the  authentication and delivery of such Certificates
or did not hold such offices at the date of such  Certificates.  No  Certificate
shall be  entitled  to any  benefit  under this  Agreement,  or be valid for any
purpose,  unless manually countersigned by a Responsible Officer of the Trustee,
or unless there  appears on such  Certificate a  certificate  of  authentication
executed   by  the   Authenticating   Agent  by  manual   signature,   and  such
countersignature or certificate upon a Certificate shall be conclusive evidence,
and the only evidence,  that such  Certificate has been duly  authenticated  and
delivered  hereunder.  All  Certificates  shall  be  dated  the  date  of  their
authentication.

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

            "Unless   this   certificate   is   presented   by   an   authorized
representative  of  [the  Clearing  Agency]  to  the  Seller  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 A-PO, Class B-4, Class B-5 or Class 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 A-PO, Class B-4,
Class B-5 or Class 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 hereto  certifying to the Seller and the Trustee the facts surrounding
such transfer,  which investment  letter shall not be an expense of the Trustee,
the Seller or the Master Servicer.  The Holder of a Class A-PO, Class B-4, Class
B-5 or Class 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  A-PO,  Class  B-4,  Class B-5 or Class B-6
Certificates under said Act or any other securities law.

            (c)   No  transfer of a Class A-PO or Class B  Certificate  shall be
made (other than the transfer of the Class A-PO  Certificates to an affiliate of
the Seller on the Closing  Date)  unless the  Trustee and the Seller  shall have
received (i) a representation  letter from the transferee in the form of Exhibit
J  hereto,  in the case of a Class  A-PO,  Class  B-4,  Class  B-5 or Class  B-6
Certificate,  or in the form of  Exhibit K hereto,  in the case of a Class  B-1,
Class  B-2 or  Class  B-3  Certificate,  to the  effect  that  either  (a)  such
transferee  is not an  employee  benefit  plan or other  retirement  arrangement
subject to Title I of ERISA or Code Section  4975,  or a  governmental  plan, as
defined in Section  3(32) of ERISA,  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
Certificates 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 is covered by Sections I and III of PTE
95-60  or (ii) in the  case  of any  such  Class  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 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 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 A-R or Class A-LR Certificate may be transferred directly or indirectly to
a "disqualified  organization"  within the meaning of Code Section 860E(e)(5) or
an agent  of a  disqualified  organization  (including  a  broker,  nominee,  or
middleman), to a Plan or a Person 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 A-R or Class
A-LR  Certificate in connection  with the conduct of a trade or business  within
the United  States and has  furnished  the  transferor  and the Trustee  with an
effective Internal Revenue Service Form 4224 or (iii) is a Non-U.S.  Person that
has delivered to both the  transferor and the Trustee an opinion of a nationally
recognized tax counsel to the effect that the transfer of the Class A-R or Class
A-LR  Certificate to it is in accordance  with the  requirements of the Code and
the regulations  promulgated  thereunder and that such transfer of the Class A-R
or Class  A-LR  Certificate  will not be  disregarded  for  federal  income  tax
purposes (any such person who is not covered by clauses (i), (ii) or (iii) above
being  referred to herein as a  "Non-permitted  Foreign  Holder"),  and any such
purported  transfer  shall be void and have no  effect.  The  Trustee  shall not
execute,  and shall not  authenticate  (or  cause  the  Authenticating  Agent to
authenticate)  and  deliver,  a new  Class  A-R or  Class  A-LR  Certificate  in
connection  with any  such  transfer  to a  disqualified  organization  or agent
thereof (including a broker,  nominee or middleman),  an ERISA Prohibited Holder
or a Non-permitted Foreign Holder, and neither the Certificate Registrar nor the
Trustee shall accept a surrender for transfer or  registration  of transfer,  or
register the transfer  of, the Class A-R or Class A-LR  Certificate,  unless the
transferor shall have provided to the Trustee an affidavit, substantially in the
form attached as Exhibit H hereto, signed by the transferee,  to the effect that
the transferee is not such a disqualified  organization,  an agent  (including a
broker, nominee, or middleman) for any entity as to which the transferee has not
received a substantially  similar  affidavit,  an ERISA  Prohibited  Holder or a
Non-permitted  Foreign Holder,  which affidavit shall contain the consent of the
transferee  to any such  amendments  of this  Agreement  as may be  required  to
further  effectuate the foregoing  restrictions  on transfer of the Class A-R or
Class A-LR Certificate to disqualified  organizations,  ERISA Prohibited Holders
or  Non-permitted  Foreign  Holders.  Such  affidavit  shall  also  contain  the
statement of the transferee  that (i) the transferee has  historically  paid its
debts  as they  have  come  due and  intends  to do so in the  future,  (ii) the
transferee  understands  that it may incur  liabilities  in excess of cash flows
generated by the residual  interest,  (iii) the transferee  intends to pay taxes
associated  with holding the  residual  interest as they become due and (iv) the
transferee  will not  transfer  the Class A-R or Class A-LR  Certificate  to any
Person who does not provide an affidavit  substantially  in the form attached as
Exhibit H hereto.

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

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

            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, or (iii) after the
occurrence of dismissal or resignation of the Master Servicer, Beneficial Owners
representing  aggregate  Voting  Interests of not less than 51% of the aggregate
Voting Interests of each outstanding 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, 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.

                                   ARTICLE VI

                       THE SELLER AND THE MASTER SERVICER

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

            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,
employee  or agent of any of them shall be entitled  to  indemnification  by the
Trust Estate and will be held  harmless  against any loss,  liability or expense
incurred in connection  with any legal action  relating to this Agreement or the
Certificates,  including,  without  limitation,  any legal  action  against  the
Trustee in its capacity as Trustee hereunder,  other than any loss, liability or
expense (including, without limitation,  expenses payable by the Master Servicer
under  Section  8.06)  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  Account,  and such amounts shall, on
the following Distribution Date or Distribution Dates, be allocated in reduction
of  distributions  on the Class A and Class B Certificates in the same manner as
Realized Losses are allocated pursuant to Section 4.02(a).

            SECTION 6.04      RESIGNATION OF THE MASTER SERVICER.

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

            SECTION 6.05      COMPENSATION TO THE MASTER SERVICER.

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

            SECTION 6.06      ASSIGNMENT  OR  DELEGATION  OF DUTIES BY MASTER
                              SERVICER.

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

            SECTION 6.08      MASTER SERVICER COVENANTS  CONCERNING YEAR 2000
                              COMPLIANCE.

            The  Master  Servicer  covenants  that it is  working  to modify its
computer  and other  systems  used in the  performance  of its  duties as master
servicer  for the  Certificates  to operate in a manner such that,  on and after
January 1, 2000, the Master  Servicer can perform its duties in accordance  with
the terms 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 FHLMC, which ineligibility
      continues unremedied for a period of 90 days.

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

            SECTION 7.02      OTHER REMEDIES OF TRUSTEE.

            During  the  continuance  of any Event of  Default,  so long as such
Event of Default shall not have been remedied,  the Trustee,  in addition to the
rights  specified  in Section  7.01,  shall  have the right,  in its own name as
trustee of an express  trust,  to take all actions now or hereafter  existing at
law, in equity or by statute to enforce its rights and  remedies  and 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 rights 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 the Certificate Account by the Master
Servicer or which are thereafter received by the Master Servicer with respect to
the Mortgage Loans.  Neither the Trustee nor any other successor master servicer
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 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 the 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 the
Certificate  Account by the Master Servicer or, in its capacity as trustee,  for
investment of any such amounts.

            SECTION 8.05      TRUSTEE MAY OWN CERTIFICATES.

            The Trustee,  and any agent thereof,  in its individual or any other
capacity,  may become the owner or pledgee of Certificates  with the same rights
it would  have if it were not  Trustee or such  agent 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,  the Trustee 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 8811 and apply for an Employee  Identification  Number with a Form SS-4 or
any other permissible method and respond to inquiries by  Certificateholders  or
their nominees  concerning  information  returns,  reports or tax returns;  (vi)
maintain (or cause to be maintained by the Servicers)  such records  relating to
the Upper-Tier REMIC and the Lower-Tier REMIC,  including but not limited to the
income, expenses, individual Mortgage Loans (including REO Mortgage Loans, other
assets and  liabilities  of each REMIC,  and the fair market  value and adjusted
basis of the  property  of each REMIC  determined  at such  intervals  as may be
required by the Code,  as may be necessary to prepare the  foregoing  returns or
information reports; (vii) exercise reasonable care not to allow the creation of
any  "interests" in either the Upper-Tier  REMIC or the Lower-Tier  REMIC within
the  meaning  of  Code  Section  860D(a)(2)  other  than  the  interests  in the
Upper-Tier REMIC  represented by the Class A-1, Class A-2, Class A-3, Class A-4,
Class A-5, Class A-6,  Class A-7, Class A-8, Class A-9, Class A-10,  Class A-11,
Class A-PO and Class A-R  Certificates  and the Class B-1, Class B-2, Class B-3,
Class  B-4,  Class B-5 and  Class  B-6  Certificates  and the  interests  in the
Lower-Tier  REMIC  represented by the Class A-L1,  Class A-L4, Class A-L9, Class
A-LPO,  Class A-LUR,  Class B-L1, Class B-L2, Class B-L3, Class B-L4, Class B-L5
and  Class  B-L6  Interests  and the Class  A-LR  Certificate;  (viii)  exercise
reasonable  care not to allow the  occurrence of any  "prohibited  transactions"
within the meaning of Code Section  860F(a),  unless the Master  Servicer  shall
have  provided an Opinion of Counsel to the Trustee that such  occurrence  would
not (a) result in a taxable gain,  (b) otherwise  subject  either the Upper-Tier
REMIC or  Lower-Tier  REMIC or the  Trust  Estate  to tax or (c) cause the Trust
Estate to fail to qualify as two separate REMICs;  (ix) exercise reasonable care
not to allow  either the  Upper-Tier  REMIC or the  Lower-Tier  REMIC to receive
income from the  performance of services or from assets not permitted  under the
REMIC  Provisions  to be held by a REMIC;  (x) pay (on behalf of the  Upper-Tier
REMIC or the Lower-Tier REMIC) the amount of any federal income tax,  including,
without  limitation,  prohibited  transaction  taxes,  taxes on net income  from
foreclosure  property,  and taxes on certain  contributions to a REMIC after the
Startup Day,  imposed on the Upper-Tier  REMIC or Lower-Tier  REMIC, as the case
may be, when and as the same shall be due and payable (but such obligation shall
not prevent the Master Servicer or any other appropriate  Person from 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 and the  Lower-Tier  REMIC  within  the  meaning of  Treasury  Regulations
Section  1.860F-4(d),  and the Master Servicer is hereby  designated as agent of
the Class A-R and Class  A-LR  Certificateholders  for such  purpose  (or if the
Master Servicer is not so permitted, the Holders of the Class A-R and Class A-LR
Certificates  shall be tax  matters  persons  for the  Upper-Tier  REMIC and the
Lower-Tier REMIC,  respectively,  in accordance with the REMIC Provisions).  The
Master Servicer shall be entitled to be reimbursed  pursuant to Section 3.02 for
any taxes paid by it pursuant to clause (x) of the preceding sentence, except to
the  extent  that such taxes are  imposed as a result of the bad faith,  willful
misfeasance or gross negligence of the Master Servicer in the performance of its
obligations  hereunder.  The Trustee  shall sign the tax returns  referred to in
clause (i) of the second preceding sentence.

            In order to enable the Master  Servicer or the Trustee,  as the case
may be, to perform its duties as set forth above,  the Seller shall provide,  or
cause to be provided,  to the Master  Servicer within ten days after the Closing
Date all information or data that the Master Servicer  determines to be relevant
for tax  purposes to the  valuations  and offering  prices of the  Certificates,
including,  without  limitation,  the price,  yield,  prepayment  assumption and
projected cash flows of each Class 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 either  REMIC as  described  above.  In the event
that the Trustee  prepares  any of the  federal,  state and local tax returns of
either 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,  respectively,  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.

            SECTION 8.16      TRUSTEE COVENANTS CONCERNING YEAR 2000

other  systems  used  in the  performance  of its  duties  as  trustee  for  the
Certificates to operate in a manner such that, on and after January 1, 2000, the
Trustee can perform its duties in accordance with the terms of this Agreement.

                                   TERMINATION

            SECTION 9.01      TERMINATION UPON PURCHASE BY THE SELLER OR
                              LIQUIDATION OF ALL MORTGAGE LOANS.

            Subject  to   Section   9.02,   the   respective   obligations   and
responsibilities  of the Seller,  the Master  Servicer  and the Trustee  created
hereby (other than the obligation of the Trustee to make certain  payments after
the Final  Distribution  Date to  Certificateholders  and the  obligation of the
Master  Servicer to send 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 Pool Scheduled  Principal  Balance 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  Certificate
Registrar at the time such notice is given to  Certificateholders.  In the event
such notice is given by the Master  Servicer,  the Master Servicer shall deposit
in  the  Certificate  Account  on or  before  the  Final  Distribution  Date  in
immediately available funds an amount equal to the purchase price for the assets
of the Trust  Estate  computed  as above  provided.  Failure  to give  notice of
termination  as described  herein shall not entitle a  Certificateholder  to any
interest beyond the interest payable on the Final Distribution Date.

            Upon  presentation  and surrender of the  Certificates,  the Trustee
shall cause to be distributed to  Certificateholders  on the Final  Distribution
Date in proportion to their respective  Percentage  Interests an amount equal to
(i) as to the Classes of Class A Certificates,  the respective Principal Balance
together  with any related  Class A Unpaid  Interest  Shortfall  and one month's
interest in an amount equal to the respective  Interest Accrual Amount,  (ii) as
to the  Classes  of  Class B  Certificates,  the  respective  Principal  Balance
together  with any related  Class B Unpaid  Interest  Shortfall  and one month's
interest in an amount equal to the respective  Interest Accrual Amount and (iii)
as to the Class A-R and Class A-LR  Certificates,  the  amounts,  if any,  which
remain on deposit in the  Upper-Tier  Certificate  Account  and the  Certificate
Account,  respectively  (other  than  amounts  retained  to meet  claims)  after
application  pursuant  to clauses  (i),  (ii) and (iii) above and payment to the
Master  Servicer of any amounts it is entitled  as  reimbursement  or  otherwise
hereunder. Such amount shall be distributed in respect of interest and principal
in respect of the  Uncertificated  Lower-Tier  Interests  in the same amounts as
distributed  to their  Corresponding  Upper-Tier  Class 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  Account not distributed in final distribution
to  Certificateholders  to be withdrawn  therefrom and credited to the remaining
Certificateholders by depositing such funds in a separate escrow account for the
benefit of such Certificateholders, and the Master Servicer (if it exercised its
right to purchase  the assets of the Trust  Estate) or the Trustee (in any other
case) shall give a second written notice to the remaining  Certificateholders to
surrender their Certificates for cancellation and receive the final distribution
with respect  thereto.  If within  three months after the second  notice all the
Certificates  shall not have been surrendered for cancellation,  the Trustee may
take appropriate  steps, or may appoint an agent to take  appropriate  steps, to
contact  the  remaining   Certificateholders   concerning   surrender  of  their
Certificates,  and the cost thereof shall be paid out of the funds on deposit in
such escrow account.

            SECTION 9.02      ADDITIONAL TERMINATION REQUIREMENTS.

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

               (i)  The notice given by the Master Servicer  under  Section 9.01
      shall  provide  that such  notice  constitutes  the  adoption of a plan of
      complete  liquidation of the Upper-Tier  REMIC and the 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 the 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 Lower-Tier  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 or
Lower-Tier  REMIC  or any of the  Certificateholders  will be  subject  to a tax
caused by a transfer to a  non-permitted  transferee  and (vi) to make any other
provisions with respect to matters or questions  arising under this Agreement or
such Custodial  Agreement  which shall not be materially  inconsistent  with the
provisions of this Agreement,  provided that such action shall not, as evidenced
by an Opinion of Counsel, adversely affect in any material respect the interests
of any Certificateholder.

            This  Agreement or any Custodial  Agreement may also be amended from
time to time by the Seller, the Master Servicer and the Trustee with the consent
of the Holders of Certificates evidencing in the aggregate not less than 66-2/3%
of the aggregate Voting Interests of each Class 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-1  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.

            SECTION 10.04     GOVERNING LAW; JURISDICTION.

            This Agreement shall be construed in accordance with the laws of the
State of New York  (without  regard to  conflicts of laws  principles),  and the
obligations, rights and remedies of the parties hereunder shall be determined in
accordance with such laws.

            SECTION 10.05     NOTICES.

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 have  knowledge  of any act or failure to act of any  Servicer  unless

this Agreement to constitute a purchase and sale and not a loan. Notwithstanding
the  foregoing,  to the extent that such  conveyance is held not to constitute a
sale under applicable law, it is intended that this Agreement shall constitute a
security  agreement under  applicable law and that the Seller shall be deemed to
have  granted to the Trustee a first  priority  security  interest in all of the
Seller's right, title and interest in and to the Mortgage Loans.

master  servicer  (the "Master  Servicer")  and First Union  National  Bank,  as

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

Certificate  is  registered at the close of business on the last Business Day of
the month  preceding the month of such  distribution,  in an amount equal to the
product of the Percentage Interest evidenced by this Certificate and the Class A
Distribution Amount for the Class A-1 Certificates required to be distributed to
Holders of the Class A-1  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 A  Certificates
may not commence on the first  Distribution Date specified above.  Distributions

accordance with the provisions of the Agreement.  The  pass-through  rate on the
Class A-1 Certificates  applicable to each  Distribution Date will be 7.000% per
annum.  The amount of interest  which accrues on this  Certificate  in any month

Shortfall and the interest  portion of certain  Realized Losses allocated to the
Class A-1 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

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,

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

                  This  Certificate  is issued on October 28, 1999, and based on
its  issue  price  of  96.07187%,  including  accrued  interest,  and  a  stated

method, is approximately 0.02575806%.

                  This Certificate  constitutes a "regular  interest" in a "real

thereto,  and which may include loans  secured by shares  issued by  cooperative
housing corporations (the "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

"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master  servicer  (the "Master  Servicer")  and First Union  National  Bank,  as

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

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

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

Distribution Amount for the Class A-5 Certificates required to be distributed to
Holders of the Class A-5  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 A  Certificates
may not commence on the first  Distribution Date specified above.  Distributions
of principal  will be  allocated  among the Classes of Class A  Certificates  in
accordance with the provisions of the Agreement.  The  pass-through  rate on the
Class A-5 Certificates  applicable to each  Distribution Date will be 7.000% per
annum.  Prior to the applicable  Accretion  Termination Date, no distribution of
interest on this  Certificate  will be made.  Prior to the applicable  Accretion
Termination  Date,   interest  otherwise  available  for  distribution  on  this
Certificate will be added to the Principal Balance of the Class A-5 Certificates
on each  Distribution  Date.  The  amount  of  interest  which  accrues  on this
Certificate  in any month  will be  subject  to  reduction  with  respect to any
Non-Supported  Interest  Shortfall and the interest  portion of certain Realized
Losses allocated to the Class A-5 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.

using the exact method, is approximately 0.51445333%.

                  This Certificate  constitutes a "regular  interest" in a "real

                  THIS   CERTIFIES  THAT   ___________________________   is  the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
monthly distributions to the Holders of the Class A-11 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 "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 October 28, 1999 (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 A
Distribution  Amount for the Class A-11 Certificates  required to be distributed
to Holders of the Class A-11 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 A  Certificates
may not commence on the first  Distribution Date specified above.  Distributions
of principal  will be  allocated  among the Classes of Class A  Certificates  in
accordance with the provisions of the Agreement.  The  pass-through  rate on the
Class A-11 Certificates  applicable to each Distribution Date will be 7.000% per
annum.  Prior to the applicable  Accretion  Termination Date, no distribution of
interest on this  Certificate  will be made.  Prior to the applicable  Accretion
Termination  Date,   interest  otherwise  available  for  distribution  on  this
Certificate  will  be  added  to  the  Principal   Balance  of  the  Class  A-11
Certificates on each Distribution  Date. The amount of interest which accrues on
this  Certificate  in any month will be subject to reduction with respect to any
Non-Supported  Interest  Shortfall and the interest  portion of certain Realized
Losses allocated to the Class A-11 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  is issued on October 28, 1999,  at an issue
price of 50.52500%, including accrued interest, and a stated redemption price at
maturity  equal to the sum of its initial  principal  balance  and all  interest
distributions  hereon (whether current or accrued),  and is issued with original
issue  discount  ("OID") for federal  income tax  purposes.  Assuming  that this
Certificate  pays  in  accordance  with  projected  cash  flows  reflecting  the
prepayment assumption of 225% SPA (as defined in the Prospectus Supplement dated
October  22,  1999 with  respect  to the  offering  of the Class A  Certificates
(except  the  Class  A-PO  Certificates),  Class  B-1,  Class  B-2 and Class B-3
Certificates)  used  to  price  this  Certificate:  (i) the  amount  of OID as a
percentage of the initial principal balance of this Certificate is approximately
104.16130000%; (ii) the annual yield to maturity of this Certificate, compounded
monthly,  is approximately  18.06%; and (iii) the amount of OID allocable to the
short  first  accrual  period  (October  28,  1999 to  November  25,  1999) as a
percentage  of the initial  principal  balance of this  Certificate,  calculated
using the exact method, is approximately 0.68390011%.

                  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.

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

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

letter,  in the form as described in the Agreement,  stating that the transferee
is not a Plan and is not  acting on  behalf  of a Plan or using the  assets of a
Plan to  effect  such  purchase  or (ii) if such  transferee  is a Plan,  (a) an
opinion of counsel  acceptable to and in form and substance  satisfactory to the
Trustee  and  the  Seller  with  respect  to  certain  matters  and  such  other
documentation as the Seller or the Master Servicer may require,  as described in
the Agreement.

(i) a representation letter, in the form as described in the Agreement,  stating

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

redemption price at maturity equal to its initial principal balance (plus 3 days
of interest at the  pass-through  rate hereon),  is issued with  original  issue

pays  in  accordance  with  projected  cash  flows   reflecting  the  prepayment
assumption of 225% SPA (as defined in the  Prospectus  Supplement  dated October
22, 1999 with  respect to the offering of the Class A  Certificates  (except the
Class A-PO Certificates),  Class B-1, Class B-2 and Class B-3 Certificates) used
to price this Certificate:  (i) the amount of OID as a percentage of the initial
principal  balance of this  Certificate is approximately  5.87708333%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  7.81%;  and (iii) the amount of OID  allocable to the short first
accrual  period  (October 28, 1999 to November 25, 1999) as a percentage  of the
initial  principal  balance  of this  Certificate,  calculated  using  the exact
method, is approximately 0.02678913%.

                  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,

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

Certificate  is  registered at the close of business on the last Business Day of
the month  preceding the month of such  distribution,  in an amount equal to the
product of the Percentage Interest evidenced by this Certificate and, subject to
the  prior  rights  of the  Class A  Certificates  and  each  Class  of  Class B
Certificates  bearing  a  lower  numerical   designation  as  specified  in  the
Agreement,  any Class B-2  Distribution  Amount  required to be  distributed  to
Holders of the Class B-2  Certificates  on such  Distribution  Date,  subject to
adjustment,  in certain events, as specified in the Agreement.  The pass-through
rate on the Class B-2 Certificates  applicable to each Distribution Date will be
7.000% per annum.  The amount of interest  which accrues on this  Certificate in
any month  will be  subject  to  reduction  with  respect  to any  Non-Supported
Interest Shortfall and the interest portion of certain Realized Losses allocated
to the Class B-2 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.

                  No transfer of a Class B-2 Certificate will be made unless the
Holder hereof  desiring to make any such  transfer  shall deliver to the Trustee
(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  is issued on October 28, 1999, and based on
its  issue  price  of  92.18125%,  including  accrued  interest,  and  a  stated
redemption price at maturity equal to its initial principal balance (plus 3 days
of interest at the  pass-through  rate hereon),  is issued with  original  issue
discount ("OID") for federal income tax purposes. Assuming that this Certificate
pays  in  accordance  with  projected  cash  flows   reflecting  the  prepayment
assumption of 225% SPA (as defined in the  Prospectus  Supplement  dated October
22, 1999 with  respect to the offering of the Class A  Certificates  (except the
Class A-PO Certificates),  Class B-1, Class B-2 and Class B-3 Certificates) used
to price this Certificate:  (i) the amount of OID as a percentage of the initial
principal  balance of this  Certificate is approximately  7.87708333%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  8.11%;  and (iii) the amount of OID  allocable to the short first
accrual  period  (October 28, 1999 to November 25, 1999) as a percentage  of the
initial  principal  balance  of this  Certificate,  calculated  using  the exact
method, is approximately 0.03540097%.

                  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.

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

                  No  transfer  of a Class B-4  Certificate  will be made unless
such transfer 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

transfer  is to be made  within  three  years  from the later of (a) the date of

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  is issued on October 28, 1999, and based on
its  issue  price  of  70.33750%,  including  accrued  interest,  and  a  stated
redemption price at maturity equal to its initial principal balance (plus 3 days
of interest at the  pass-through  rate hereon),  is issued with  original  issue
discount ("OID") for federal income tax purposes. Assuming that this Certificate
pays  in  accordance  with  projected  cash  flows   reflecting  the  prepayment
assumption of 225% SPA (as defined in the  Prospectus  Supplement  dated October
22, 1999 with  respect to the offering of the Class A  Certificates  (except the
Class A-PO Certificates),  Class B-1, Class B-2 and Class B-3 Certificates) used
to price this Certificate:  (i) the amount of OID as a percentage of the initial
principal  balance of this Certificate is approximately  29.72083333%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  12.09%;  and (iii) the amount of OID allocable to the short first
accrual  period  (October 28, 1999 to November 25, 1999) as a percentage  of the
initial  principal  balance  of this  Certificate,  calculated  using  the exact
method, is approximately 0.11240564%.

                  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.

(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  is issued on October 28, 1999, and based on
its  issue  price  of  18.52500%,  including  accrued  interest,  and  a  stated
redemption price at maturity equal to its initial principal balance (plus 3 days
of interest at the  pass-through  rate hereon),  is issued with  original  issue
discount ("OID") for federal income tax purposes. Assuming that this Certificate
pays  in  accordance  with  projected  cash  flows   reflecting  the  prepayment
assumption of 225% SPA (as defined in the  Prospectus  Supplement  dated October
22, 1999 with  respect to the offering of the Class A  Certificates  (except the
Class A-PO Certificates),  Class B-1, Class B-2 and Class B-3 Certificates) used
to price this Certificate:  (i) the amount of OID as a percentage of the initial
principal  balance of this Certificate is approximately  81.53333333%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  45.46%;  and (iii) the amount of OID allocable to the short first
accrual  period  (October 28, 1999 to November 25, 1999) as a percentage  of the
initial  principal  balance  of this  Certificate,  calculated  using  the exact
method, is approximately 0.10548722%.

                  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 1999-24 Certificates]

                      NORWEST ASSET SECURITIES CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATES
                                 SERIES 1999-24

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

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

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Seller,  the Master Servicer,  and the Trustee and the rights
of the  Certificateholders  under the  Agreement at any time by the Seller,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing  in the  aggregate  not less than 66 2/3% of the Voting  Interests of
each Class 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 Pool  Scheduled  Principal
Balance  of the  Mortgage  Loans as of the  Distribution  Date  upon  which  the
proceeds of such repurchase are  distributed  being less than ten percent of the
Cut-Off Date Aggregate Principal Balance.

                  WHEREAS,  the Seller,  the Master  Servicer,  and the Trustee,
have entered into a Pooling and Servicing Agreement dated as of October 28, 1999
relating to the issuance of Mortgage Pass-Through  Certificates,  Series 1999-24
(as in effect on the date of this Agreement, the "Original Pooling and Servicing
Agreement",  and as amended and supplemented from time to time, the "Pooling and
Servicing Agreement"); and

                  WHEREAS,  the  Custodian  has  agreed  to act as agent for the
Trustee for the purposes of receiving  and holding  certain  documents and other
instruments  delivered by the Seller under the Pooling and Servicing  Agreement,
all upon the terms and conditions and subject to the limitations hereinafter set

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

                                    ARTICLE I

                                   DEFINITIONS

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

                                   ARTICLE II

                          CUSTODY OF MORTGAGE DOCUMENTS

                  Section  2.01  Custodian  to  Act  as  Agent;   Acceptance  of
Custodial Files.  The Custodian,  as the duly appointed agent of the Trustee for
these purposes,  acknowledges receipt of the Mortgage Notes, the Mortgages,  the
assignments and other documents relating to the Mortgage Loans identified on the
schedule  attached hereto and declares that it holds and will hold such Mortgage
Notes,  Mortgages,  assignments  and other  documents and any similar  documents
received by the Trustee subsequent to the date hereof (the "Custodial Files") as
agent for the  Trustee,  in trust,  for the use and  benefit of all  present and
future Certificateholders.

                  Section 2.02 Recordation of Assignments. If any Custodial File
includes one or more  assignments  to the Trustee of Mortgage  Notes and related
Mortgages that have not been recorded,  each such assignment  shall be delivered
by  the  Custodian  to  the  Seller  for  the  purpose  of  recording  it in the
appropriate  public  office for real  property  records,  and the Seller,  at no
expense to the Custodian, shall promptly cause to be recorded in the appropriate
public office for real property  records each such  assignment and, upon receipt
thereof  from such  public  office,  shall  return each such  assignment  to the
Custodian.

                  Section 2.03 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 2.04 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  2.05  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  2.06  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 3.01 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  3.02  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 3.03 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  3.04  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  3.05   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 3.06  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 3.07  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.

COUNTY OF                   )

                  [NAME OF OFFICER], being first duly sworn, deposes and says:

         (1)  That  he is  [Title  of  Officer]  of  [Name  of  Purchaser]  (the

this affidavit.

         (2)  That the Purchaser's Taxpayer Identification Number is [        ].

         (3) That the Purchaser is not a "disqualified  organization" within the
meaning of Section  860E(e)(5),of  the Internal Revenue Code of 1986, as amended
(the "Code"),  or an ERISA  Prohibited  Holder,  and will not be a "disqualified
organization" or an ERISA Prohibited Holder, as of [date of transfer],  and that
the Purchaser is not acquiring  Norwest Asset  Securities  Corporation  Mortgage
Pass-Through  Certificates,  Series 1999-24, Class [A-R] [A-LR] Certificate (the
"Class [A-R] [A-LR]  Certificate")  for the account of, or as agent (including a
broker, nominee, or other middleman) for, any person or entity from which it has
not received an affidavit substantially in the form of this affidavit. For these
purposes,  a "disqualified  organization"  means the United States, any state or
political  subdivision  thereof,  any  foreign  government,   any  international
organization,  any agency or instrumentality of any of the foregoing (other than
an instrumentality if all of its activities are subject to tax and a majority of
its  board of  directors  is not  selected  by such  governmental  entity),  any
cooperative  organization  furnishing  electric  energy or  providing  telephone
service to persons in rural areas as described in Code Section 1381(a)(2)(C), or
any organization  (other than a farmers'  cooperative  described in Code Section
521) that is exempt from  taxation  under the Code unless such  organization  is
subject to the tax on unrelated business income imposed by Code Section 511. For
these purposes,  an "ERISA Prohibited  Holder" means an employee benefit plan or
other  retirement  arrangement  subject  to Title I of the  Employee  Retirement
Income  Security Act of 1974,  as amended  ("ERISA"),  or Code Section 4975 or a

provisions of ERISA or the Code  (collectively,  a "Plan") or a Person acting on
behalf of or investing the assets of such a Plan.

         (4) That the  Purchaser  historically  has paid its  debts as they have
come due and  intends  to pay its debts as they come due in the  future  and the
Purchaser  intends to pay taxes  associated  with holding the Class [A-R] [A-LR]
Certificate as they become due.

         (5) That the Purchaser  understands  that it may incur tax  liabilities
with  respect  to the Class  [A-R]  [A-LR]  Certificate  in excess of cash flows
generated by the Class [A-R] [A-LR] Certificate.

         (6) That the  Purchaser  will  not  transfer  the  Class  [A-R]  [A-LR]
Certificate to any person or entity from which the Purchaser has not received an
affidavit  substantially  in the  form of this  affidavit  and as to  which  the
Purchaser has actual knowledge that the requirements set forth in paragraph 3, 4
or 7 hereof are not  satisfied or that the Purchaser has reason to know does not
satisfy the requirements set forth in paragraph 4 hereof.

         (7) That the Purchaser  (i) is a U.S.  Person or (ii) is a person other

Certificate  in  connection  with the conduct of a trade or business  within the
United States and has furnished the transferor and the Trustee with an effective
Internal  Revenue  Service  Form 4224 or  successor  form at the time and in the
manner required by the Code or (iii) is a Non-U.S.  Person that has delivered to
both the  transferor  and the Trustee an opinion of a nationally  recognized tax
counsel to the effect that the transfer of the Class [A-R] [A-LR] Certificate to
it is in  accordance  with the  requirements  of the  Code  and the  regulations
promulgated  thereunder  and  that  such  transfer  of the  Class  [A-R]  [A-LR]
Certificate  will not be  disregarded  for federal  income tax  purposes.  "U.S.
Person"  means a citizen or resident of the United  States,  a  corporation,  or
partnership  (unless,  in the case of a partnership,  Treasury  regulations  are
adopted that provide otherwise) created or organized in or under the laws of the
United States any state thereof or the District of Columbia, including an entity
treated as a corporation  or  partnership  for federal  income tax purposes,  an
estate  whose income is subject to U.S.  federal  income tax  regardless  of its
source  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).

         (8) That the  Purchaser  agrees to such  amendments  of the Pooling and
Servicing Agreement as may be required to further effectuate the restrictions on
transfer of the Class A-R Certificate to such a "disqualified  organization," an
agent thereof,  an ERISA Prohibited Holder or a person that does not satisfy the
requirements of paragraph 4, paragraph 5 and paragraph 7 hereof.

         (9)  That the  Purchaser  consents  to the  designation  of the  Master
Servicer as its agent to act as "tax matters person" of the  [Upper-Tier  REMIC]
[Lower-Tier  REMIC]  pursuant  to  Section  3.01 of the  Pooling  and  Servicing
Agreement,  and if such  designation is not permitted by the Code and applicable
law, to act as tax matters person if requested to do so.

information (including documents) relevant to its decision to purchase the Class
[A-PO][B-4][B-5][B-6]  Certificates  that the Seller  possesses  or can  possess

independent  analysis  of  the  investment  in the  Class  [A-PO][B-4][B-5][B-6]

Certificates.

                  (e) Either (i) the  Purchaser is not an employee  benefit plan
or other retirement  arrangement  subject to Title I of the Employee  Retirement
Income  Security  Act of 1974,  as amended,  ("ERISA"),  or Section  4975 of the
Internal Revenue Code of 1986, as amended (the "Code"),  or a governmental plan,
as defined in Section 3(32) of ERISA subject to any federal,  state or local law
("Similar  Law")  which is,  to a  material  extent,  similar  to the  foregoing
provisions  of ERISA or the Code  (collectively,  a "Plan"),  an agent acting on

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

                  (f) If the  Purchaser is a depository  institution  subject to
the jurisdiction of the Office of the Comptroller of the Currency  ("OCC"),  the
Board of Governors of the Federal  Reserve System  ("FRB"),  the Federal Deposit
Insurance Corporation ("FDIC"),  the Office of Thrift Supervision ("OTS") or the
National Credit Union  Administration  ("NCUA"),  the Purchaser has reviewed the
"Supervisory Policy Statement on Securities  Activities" dated April 29, 1992 of
the Federal Financial  Institutions  Examination  Council and the April 15, 1994
Interim  Revision  thereto as adopted by the OCC, FRB,  FDIC, OTS and NCUA (with
modifications  as  applicable),  as  appropriate,  other  applicable  investment
authority,  rules, supervisory policies and guidelines of these agencies and, to
the extent  appropriate,  state banking  authorities  and has concluded that its
purchase  of  the  Class  [A-PO][B-4][B-5][B-6]  Certificates  is in  compliance
therewith.

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

                  (a)    The    Purchaser    understands    that    the    Class
[A-PO][B-4][B-5][B-6] Certificates have not been registered under the Securities
Act of 1933 (the "Act") or any state securities laws and that no transfer may be
made unless the Class  [A-PO][B-4][B-5][B-6]  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
[A-PO][B-4][B-5][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 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  [A-PO][B-4][B-5][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
[A-PO][B-4][B-5][B-6]  Certificates  bear a legend  setting forth the applicable
restrictions on transfer.

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

                  Section 1. Definitions.  Each capitalized term used herein and
not  otherwise  defined  herein  shall have the  meaning  ascribed  to it in the
Pooling and Servicing Agreement,  dated as of October 28, 1999 (the "Pooling and
Servicing Agreement") among Norwest Asset Securities Corporation, as seller (the
"Seller"), Norwest Bank Minnesota, National Association, as master servicer (the

                  Section 2. Representations and Warranties of the Purchaser. In
connection with the proposed transfer,  the Purchaser represents and warrants to
the Seller, the Master Servicer and the Trustee that:

                  Either (i) the  Purchaser  is not an employee  benefit plan or
other  retirement  arrangement  subject  to Title I of the  Employee  Retirement
Income  Security  Act of 1974,  as amended,  ("ERISA"),  or Section  4975 of the
Internal Revenue Code of 1986, as amended (the "Code"),  or a governmental plan,
as defined in Section 3(32) of ERISA subject to any federal,  state or local law
("Similar  Law")  which is,  to a  material  extent,  similar  to the  foregoing
provisions  of ERISA or the Code  (collectively,  a "Plan"),  an agent acting on
behalf  of a Plan,  or a person  utilizing  the  assets of a Plan or (ii) if the
Purchaser is an insurance company,  (A) the source of funds used to purchase the
Class [B-1] [B-2] [B-3]  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,  exceed 10%
of the total of all reserves and  liabilities  of such general  account (as such

and the  Trustee of the Trust  Estate and (b) such other  opinions  of  counsel,
officers'  certificates  and agreements as the Seller or the Master Servicer may
have  required.  A Benefit  Plan  Opinion is an opinion of counsel to the effect
that the proposed  transfer  will not cause the assets of the Trust Estate to be
regarded as "plan assets" and subject to the prohibited  transaction  provisions
of ERISA,  the Code or Similar Law and will not subject the Trustee,  the Seller
or the Master Servicer to any obligation in addition to those  undertaken in the
Pooling and Servicing Agreement  (including any liability for civil penalties or
excise  taxes  imposed  pursuant to ERISA,  Section  4975 of the Code or Similar

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

                     (i) Within five Business Days after each  Distribution Date
         (or included in or with the monthly  statements  to  Certificateholders
         pursuant to the Pooling and Servicing  Agreement),  the Company,  shall
         provide  to the  Purchaser  a report,  using the same  methodology  and

         sixty days, (C) ninety days or more  delinquent or (D) in  foreclosure,
         and  indicating  for  each  such  Mortgage  Loan the  loan  number  and
         outstanding principal balance.

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

                  (b) If requested by the Purchaser, the Company shall cause 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 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
Mortgage  Loan that is at least ninety days  delinquent  and each  Mortgage Loan
which has become  real estate  owned,  through  the final  liquidation  thereof;
provided,   that  the  related  Servicer  shall  only  be  required  to  provide
information  that  is  readily  accessible  to its  servicing  personnel  and is
non-confidential  provided,  however,  that the  Purchaser  will  reimburse  the
Company and the related Servicer for any out of pocket expenses.

                  Section  6.02   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  Mortgage  Loan in  accordance  with its normal  foreclosure
policies without further notice to the Purchaser.  Any foreclosure that has been
initiated  may be  discontinued  (i)  without  notice  to the  Purchaser  if the
Mortgage Loan has been brought current or if a refinancing or prepayment  occurs
with respect to the Mortgage Loan (including by means of a short payoff approved
by the related  Servicer) or (ii) if the related  Servicer has reached the terms
of a forbearance  agreement  with the borrower.  In 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 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  Mortgage  Loan  as to  which  the
Purchaser has made an Election to Delay Foreclosure,  the Purchaser shall obtain
a  Current  Appraisal  as soon as  practicable,  but in no  event  more  than 15
business  days  thereafter,  and shall  provide the Company  with a copy of such
Current Appraisal.

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

                  (e)  With  respect  to  any  Mortgage  Loan  as to  which  the
Purchaser  has made an Election to Delay  Foreclosure,  the Company may withdraw
from the  Collateral  Fund from time to time amounts  necessary to reimburse the
related  Servicer  for all related  Monthly  Advances and  Liquidation  Expenses
thereafter  made by such Servicer in  accordance  with the Pooling and Servicing
Agreement and the related Servicing Agreement.  To the extent that the amount of
any such  Liquidation  Expenses is  determined by the Company based on estimated
costs,  and the actual  costs are  subsequently  determined  to be  higher,  the
Company may withdraw the  additional  amount from the  Collateral  Fund.  In the
event  that the  Mortgage  Loan is  brought  current  by the  mortgagor  and the
foreclosure action is discontinued, the amounts so withdrawn from the Collateral
Fund shall be redeposited 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  Mortgage  Loan is  brought  current  by the
mortgagor,  all  amounts  remaining  in the  Collateral  Fund in respect of such
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  Mortgage  Loan  as to  which  the
Purchaser has made an Election to Delay Foreclosure,  the related Servicer shall
continue  to  service  the  Mortgage  Loan  in  accordance  with  its  customary
procedures  (other than the delay in  Commencement  of  Foreclosure  as provided
herein).  If and when the  Purchaser  shall  notify the Company that it believes
that it is  appropriate  to do so, the related  Servicer  may  proceed  with the
Commencement of  Foreclosure.  In any event, if the Mortgage Loan is not brought
current by the mortgagor by the time the loan becomes 6 months  delinquent,  the
Purchaser's election shall no longer be effective and at the Purchaser's option,
either (i) the Purchaser shall purchase the Mortgage Loan from the related Trust
Estate  at a  purchase  price  equal  to the fair  market  value as shown on the
Current Appraisal, to be paid by (x) applying any balance in the Collateral Fund
to such to such purchase price, and (y) to the extent of any deficiency, by wire
transfer 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
Mortgage  Loan as to which the Purchaser  made an Election to Delay  Foreclosure
and as to  which  the  related  Servicer  proceeded  with  the  Commencement  of
Foreclosure in accordance with subsection (f) above, the Company shall calculate
the amount, if any, by which the value shown on the Current  Appraisal  obtained
under  subsection  (c) exceeds the actual  sales price  obtained for the related
Mortgaged Property (net of Liquidation  Expenses and accrued interest related to
the extended  foreclosure  period), and the Company shall withdraw the amount of
such excess from the Collateral  Fund,  shall remit the same to the Trust Estate
and in its  capacity as Master  Servicer  shall apply such amount as  additional
Liquidation  Proceeds  pursuant to the Pooling and  Servicing  Agreement.  After
making such withdrawal,  all amounts remaining in the Collateral Fund in respect
of such  Mortgage  Loan (after  adjustment  for all  permitted  withdrawals  and
deposits pursuant to this Agreement) shall be released to the Purchaser.

                  Section 6.03   Purchaser's  Election  to  Commence Foreclosure
Proceedings.

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

                  (b)  Within  two  Business  Days of  making  any  Election  to
Foreclose,  the  Purchaser  shall  remit  to the  Company,  for  deposit  in the
Collateral Fund, an amount,  as calculated by the Company,  equal to 125% of the
current unpaid principal  balance of the Mortgage Loan and three months interest
on the Mortgage Loan at the applicable  Mortgage  Interest Rate. If and when any
such  Mortgage  Loan is brought  current by the  mortgagor,  all  amounts in the
Collateral  Fund in respect of such  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  Mortgage  Loan upon the  failure of the  Purchaser  to deposit the above
amounts  relating to the Mortgage  Loan within two Business Days of the Election
to Foreclose subject to Section 3.01.

                  (c)  With  respect  to  any  Mortgage  Loan  as to  which  the
Purchaser has made an Election to Foreclose, the related Servicer shall continue
to service the Mortgage Loan in accordance with its customary  procedures (other
than Commencement of Foreclosure as provided herein).  In connection  therewith,
the Company shall have the same rights to make  withdrawals for Monthly Advances
and 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 Mortgage Loan, or (iii) the
Company or related Servicer  reasonably  believes the Mortgaged  Property may be
contaminated with or affected by hazardous wastes or hazardous  substances (and,
without  limiting  the  related   Servicer's  right  not  to  proceed  with  the
Commencement of Foreclosure, the Company supplies the Purchaser with information
supporting  such  belief).  Any  foreclosure  that  has  been  initiated  may be
discontinued  (x) without  notice to the Purchaser if the Mortgage Loan has been
brought  current or if a refinancing  or  prepayment  occurs with respect to the
Mortgage Loan  (including by means of a short payoff  approved by the Purchaser)
or (y) with  notice to the  Purchaser  if the related  Servicer  has reached the
terms of a forbearance  agreement unless  instructed  otherwise by the Purchaser
within two Business Days of such  notification.  Any such  instruction  shall be
based upon a decision that such forbearance  agreement is not in conformity with
reasonable servicing practices.

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

                  Section 6.04 Termination.

                  (a) With respect to all Mortgage  Loans  included in the Trust
Estate,  the Purchaser's  right to make any Election to Delay Foreclosure or any
Election to Foreclose  and the  Company's  obligations  under Section 2.01 shall
terminate (i) at such time as the Principal  Balance of the Class B Certificates
has been  reduced  to zero,  (ii) if the  greater  of (x) 43% (or such  lower or
higher percentage that represents the related  Servicer's actual historical loss
experience  with respect to the Mortgage Loans in the related pool as determined
by the Company) of the aggregate  principal  balance of all Mortgage  Loans that
are in  foreclosure or are more than 90 days  delinquent on a contractual  basis
and REO  properties  or (y) the  aggregate  amount  that the  Company  estimates
through the normal servicing  practices of the related Servicer will be required
to be withdrawn  from the  Collateral  Fund with respect to Mortgage Loans as to
which the Purchaser has made an Election to Delay  Foreclosure or an Election to
Foreclosure,  exceeds  (z) the  then-current  principal  balance  of the Class B
Certificates,  (iii) upon any transfer by the  Purchaser of any interest  (other
than the minority interest therein,  but only if the transferee provides written
acknowledgment  to the Company of the Purchaser's  right hereunder and that such
transferee will have no rights  hereunder) in the Class B Certificates  (whether
or not such transfer is registered  under the Pooling and Servicing  Agreement),
including any such transfer in connection with a termination of the Trust Estate
or (iv) 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  Mortgage  Loan as to  which  the  Purchaser  made any
Election to Delay Foreclosure or any Election to Foreclose and the withdrawal of
all remaining  amounts in the  Collateral  Fund as provided  herein and (ii) ten
Business Days' notice.  The  Purchaser's  right to make an election  pursuant to
Section 2.02 or Section 2.03 hereof with respect to a particular  Mortgage  Loan
shall terminate 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 VII

                       COLLATERAL FUND; SECURITY INTEREST

                  Section 7.01 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 1999-24. 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  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 7.02 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 7.03 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 7.04 Collateral Shortfalls.

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