ITEM 5.     OTHER EVENTS
            ------------

On  January  28,  1999,  Norwest  Asset  Securities   Corporation,   a  Delaware
corporation (the "Registrant"),  sold Mortgage Pass-Through Certificates, Series
1999-3,  Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-R, Class
B-1, Class B-2 and Class B-3 (the "Offered  Certificates"),  having an aggregate
original principal balance of $248,438,100. The Offered Certificates were issued
pursuant to a Pooling and  Servicing  Agreement,  dated as of January 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  1999-3,  Class  A-PO
Certificates,  having an aggregate initial principal balance of $442,000.98, and
Class B-4,  Class B-5 and Class B-6  Certificates,  having an aggregate  initial
principal  balance of  $1,125,485.88  (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  99.37%  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,
originated in connection  with the relocation of employees by various  corporate
employers that participated in the relocation program of Norwest Mortgage,  Inc.
and of employees of various non-participant  employees.  The remaining undivided
interests in the Trust Estate are  evidenced by the Class A-PO and Private Class
B Certificates  distributions  on which 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 a REMIC for federal income
tax purposes (the  "REMIC").  The Class A-1,  Class A-2,  Class A-3,  Class A-4,
Class A-5, 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 REMIC and
the Class A-R  Certificate  will be treated as the  "residual  interest"  in the
REMIC.

                  omitted or  suffered to be done by the  Trustee,  the Seller

                          CONVEYANCE OF MORTGAGE LOANS;
                      ORIGINAL ISSUANCE OF THE CERTIFICATES

     Section 2.01   Conveyance of Mortgage Loans.

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

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

In lieu of recording an assignment of any Mortgage the Seller may, to the extent
set  forth  in the  applicable  Servicing  Agreement,  deliver  or  cause  to be
delivered to the Trustee the  assignment of the Mortgage Loan from the Seller to
the Trustee in a form  suitable  for  recordation,  together  with an Opinion of
Counsel to the effect that  recording is not  required to protect the  Trustee's
right,  title and  interest  in and to the related  Mortgage  Loan or, in case a
court should  recharacterize  the sale of the Mortgage Loans as a financing,  to
perfect  a first  priority  security  interest  in favor of the  Trustee  in the
related  Mortgage Loan. In the event that the Master  Servicer  receives  notice
that  recording  is  required to protect  the right,  title and  interest of the
Trustee in and to any such Mortgage Loan for which  recordation of an assignment
has not previously been required,  the Master Servicer shall promptly notify the
Trustee  and the  Trustee  shall  within  five  Business  Days  (or  such  other
reasonable  period of time mutually  agreed upon by the Master  Servicer and the
Trustee)  of its  receipt of such  notice  deliver  each  previously  unrecorded
assignment to the related Servicer for recordation.

     Section 2.02   Acceptance by Trustee.

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

In the case of a repurchased Mortgage Loan or property, the purchase price shall
be deposited by the Seller in the Certificate  Account  maintained by the Master
Servicer  pursuant to Section 3.01. In the case of a Substitute  Mortgage  Loan,
the Owner Mortgage Loan File relating  thereto shall be delivered to the Trustee
and the  Substitution  Principal  Amount,  together  with (i)  interest  on such
Substitution  Principal  Amount at the applicable Net Mortgage  Interest Rate to
the following Due Date of such Mortgage Loan which is being  substituted for and
(ii) an amount equal to the aggregate amount of unreimbursed  Periodic  Advances
in respect of interest  previously made by the Servicer,  the Master Servicer or
the Trustee  with  respect to such  Mortgage  Loan,  shall be  deposited  in the
Certificate Account. The Monthly Payment on the Substitute Mortgage Loan for the
Due Date in the month of  substitution  shall  not be part of the Trust  Estate.
Upon receipt by the Trustee of written  notification  of any such deposit signed
by an officer of the Seller,  or the new Owner  Mortgage  Loan File, as the case
may be, the Trustee shall release to the Seller the related Owner  Mortgage Loan
File and shall execute and deliver such instrument of transfer or assignment, in
each case  without  recourse,  as shall be necessary to vest in the Seller legal
and beneficial  ownership of such  substituted  or repurchased  Mortgage Loan or
property.  It is  understood  and agreed  that the  obligation  of the Seller to
substitute a new Mortgage Loan for or  repurchase  any Mortgage Loan or property
as to which  such a  material  defect in a  constituent  document  exists  shall
constitute   the  sole  remedy   respecting   such  defect   available   to  the
Certificateholders  or the  Trustee  on  behalf of the  Certificateholders.  The
failure of the Trustee to give any notice  contemplated herein within forty-five
(45) days after the execution of this Agreement  shall not affect or relieve the
Seller's  obligation  to  repurchase  any Mortgage Loan pursuant to this Section
2.02.

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

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

            1.    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:

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

                  b.    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;

                  c.    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;

                  d.    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

               (i) 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.

            2.    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:

                  a.    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;

                  b.    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;

                  c.    The Mortgage is a valid,  subsisting  and  enforceable
                        first lien on the property therein described,  and the
                        Mortgaged   Property   is  free   and   clear  of  all

                        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

                        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,

                        subsisting  first  lien  on  the  property   described
                        therein  and the  Seller  has  full  right to sell and
                        assign the same to the Trustee;

                  d.    Neither  the  Seller  nor  any  prior  holder  of  the
                        Mortgage or the  related  Mortgage  Note has  modified

                        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;

               (ii) All taxes, governmental assessments, insurance premiums, and
      water, sewer and municipal charges,  which previously became due and owing
      have been paid, or an escrow of funds has been established,  to the extent
      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;

               (iii)  The  Mortgaged  Property  is  undamaged  by  water,  fire,
      earthquake,  earth  movement  other  than  earthquake,  windstorm,  flood,
      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;

                  e.    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
                                        --------   -------

                        policy  affording,  in substance,  the same protection
                        afforded by this  warranty is furnished to the Trustee
                        by the Seller;

                        Mortgage  Loans  secured  by   residential   long-term

                        the related title insurance  policy);  and to the best
                        of the Seller's knowledge,  the Mortgaged Property and
                        all improvements  thereon comply with all requirements
                        of any  applicable  zoning  and  subdivision  laws and
                        ordinances;

                  g.    The Mortgage Loan meets,  or is exempt from,  applicable
                        state   or   federal   laws,   regulations   and   other
                        requirements, pertaining to usury, and the Mortgage Loan

      all occupied  portions of the Mortgaged  Property and, with respect to the
      use and occupancy of the same, including, but not limited to, certificates
      of  occupancy  and  fire  underwriting  certificates,  have  been  made or

                        which  would  impair the  coverage  of such  mortgagee
                        title insurance policy;

                  j.    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

                        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

                        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;

                  k.    To the  best of the  Seller's  knowledge,  there is no

                        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;

                  l.    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;

                  m.    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;

                  n.    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;

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

                  p.    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;

                  q.    The  Mortgage  Loan is a "qualified  mortgage"  within
                        the meaning of Section 860G(a)(3) of the Code;

                  r.    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;

                  s.    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

                  t.    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

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.

            3.    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

                  Certificateholders,  and such obligation shall survive until

                  ADMINISTRATION OF THE TRUST ESTATE: SERVICING
                              OF THE MORTGAGE LOANS

     Section 3.01   Certificate Account.

            1.    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.

            2.    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:

                  a.    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

                  b.    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.

            3.    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 the  Trust  Estate  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.

            4.    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.

            1.    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):

                  a.    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;

                  b.    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;

                  c.    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;

                  d.    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;

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

               (ix) 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;

                  e.    to remit funds to the Paying  Agent in the amounts and
                        in the manner provided for herein;

                  f.    to pay to the Master  Servicer any interest  earned on
                        or  investment  income  with  respect  to funds in the
                        Certificate Account;

                  g.    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;

                  h.    to  clear  and  terminate  the   Certificate   Account
                        pursuant to Section 9.01; and

               (xi) 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.

            2.    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.

            1.    In the event an Other  Servicer  fails to make any  required
                  Periodic  Advances of  principal  and interest on a Mortgage
                  Loan as required by the related  Other  Servicing  Agreement
                  prior  to the  Distribution  Date  occurring  in  the  month
                  during  which  such  Periodic  Advance  is due,  the  Master
                  Servicer   shall  make  Periodic   Advances  to  the  extent
                  provided  hereby.  In  addition,  if under  the  terms of an
                  Other Servicing  Agreement,  the applicable  Servicer is not
                  required to make  Periodic  Advances  on a Mortgage  Loan or
                  REO Mortgage Loan through the  liquidation  of such Mortgage
                  Loan  or REO  Mortgage  Loan,  the  Master  Servicer  to the
                  extent  provided  hereby  shall make the  Periodic  Advances
                  thereon  during the period the Servicer is not  obligated to
                  do so.  In the  event  Norwest  Mortgage  fails  to make any
                  required  Periodic  Advances of principal  and interest on a
                  Mortgage   Loan  as  required   by  the  Norwest   Servicing
                  Agreement  prior to the  Distribution  Date occurring in the
                  month  during  which  such  Periodic  Advance  is  due,  the
                  Trustee shall,  to the extent required by Section 8.15, make
                  such  Periodic   Advance  to  the  extent  provided  hereby,
                  provided  that  the  Trustee  has  previously  received  the
                  certificate  of  the  Master   Servicer   described  in  the
                  following  sentence.  The Master  Servicer  shall certify to
                  the Trustee with respect to any such  Distribution  Date (i)
                  the  amount  of  Periodic   Advances   required  of  Norwest
                  Mortgage  or such Other  Servicer,  as the case may be, (ii)
                  the amount  actually  advanced  by Norwest  Mortgage or such
                  Other Servicer,  (iii) the amount that the Trustee or Master
                  Servicer  is required to advance  hereunder,  including  any
                  amount the Master  Servicer is required to advance  pursuant
                  to the second  sentence  of this  Section  3.03(a)  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.

            2.    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.

            3.    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).

            4.    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 3.02   Reports to the Trustee;
                     Annual Compliance Statements.

            1.    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.

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

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

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

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

            1.    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.

            2.    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.

            (b) (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).

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

     Section 3.08   Oversight of Servicing.

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

            twentieth,  to the  Class  B-6  Certificates  in an amount up to the

            twenty-first,  to the  Class B-6  Certificates  in an amount up to

      Class A-PO Deferred Amount as provided in Paragraph fourth above; and

            twenty-third, to the Holder of the Class A-R Certificate.

Notwithstanding  the foregoing,  after the Principal Balance of any Class (other
than the Class A-R  Certificate)  has been  reduced to zero,  such Class will be
entitled  to no further  distributions  of  principal  or  interest  (including,
without limitation, any Unpaid Interest Shortfalls).

In addition,  Net Foreclosure Profits, if any, with respect to such Distribution
Date  minus any  portion  thereof  payable  to a  Servicer  pursuant  to Section
3.02(ix) hereof shall be distributed to the Holder of the Class A-R Certificate.

With respect to any Distribution  Date, the amount of the Principal  Adjustment,
if any,  attributable to any Class of Class B Certificates  will be allocated to
the Classes of Class A Certificates (other than the Class A-PO Certificates) and
any Class of Class B Certificates  with a lower  numerical  designation pro rata
based on their Principal Balances.

            2.    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,
the Accrual Distribution Amount will be allocated sequentially as follows:

            first, to the Class A-3 Certificates,  until the Principal Balance
      thereof has been reduced to zero; and

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

II.  The Class A Non-PO  Principal  Amount  will be  allocated  sequentially  as
follows:

            first,  to the Class A-5  Certificates,  up to the Priority Amount
      for such Distribution Date;

            second, to the Class A-R Certificate,  until the Principal Balance
      thereof has been reduced to zero;

            third,  to the Class A-1  Certificates,  up to their PAC Principal
      Amount for such Distribution Date;

            fourth, to the Class A-2  Certificates,  up to their PAC Principal
      Amount for such Distribution Date;

            fifth, sequentially, to the Class A-3 and Class A-4 Certificates, in
      that  order,  until the  Principal  Balance  of each  such  Class has been
      reduced to zero;

            sixth, sequentially, to the Class A-1 and Class A-2 Certificates, in
      that order,  without regard to their respective PAC Principal  Amounts for
      such Distribution Date, until the Principal Balance of each such Class has
      been reduced to zero; and

            seventh,  to the  Class  A-5  Certificates,  without  regard  to the
      Priority Amount for such  Distribution  Date, until the Principal  Balance
      thereof has been reduced to zero.

As used above, the "PAC Principal  Amount" for any Distribution Date and for any
Distribution  Date and for any Class of PAC  Certificates  means the amount,  if
any, that would reduce the Principal  Balance of such Class to the percentage of
its Original  Principal Balance shown in the tables set forth below with respect
to such Distribution Date.

The following tables set forth for each  Distribution Date the planned Principal
Balances for the PAC  Certificates,  expressed  as a percentage  of the Original
Principal Balance of such Class.

                 AS PERCENTAGES OF ORIGINAL PRINCIPAL BALANCE

                             CLASS A-1 CERTIFICATES

            3.    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).

            4.    (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:

                           i. 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

                           ii.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

                           iii. 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

                           iv.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

                           v. 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.

               b. 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.

            5.    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  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(e)  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 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-R  Certificate)  or the  Principal  Balance  of any  Class  of  Class B
Certificates  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).

            6.    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,  partnership  (except to the extent provided in
                  applicable Treasury  regulations) or other entity created or
                  organized  in or under the laws of the United  States or any
                  political  subdivision thereof, an estate that is subject to
                  United States  federal  income tax  regardless of the source
                  of its  income  or a trust  if a  court  within  the  United
                  States  is able to  exercise  primary  supervision  over the
                  administration  of such  trust,  and one or more  such  U.S.
                  Persons  have  the  authority  to  control  all  substantial
                  decisions  of such trust  (or,  to the  extent  provided  in
                  applicable   Treasury   regulations,   certain   trusts   in
                  existence  on August 20, 1996 which are eligible to elect to
                  be treated as U.S. Persons).

     Section 4.02   Allocation of Realized Losses.

            1.    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.

            2.    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.

            3.    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.

            4.    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.

            (c) 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.

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

     Section 4.03   Paying Agent.

            (e) 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.

            (f) 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.

               (xxii)  the  amount of the  aggregate  Servicing  Fees and Master

and shall  deliver a copy of each type of statement  to the  Trustee,  who shall
provide  copies  thereof to  Persons  making  written  request  therefor  at the
Corporate Trust Office.

In the  case  of  information  furnished  with  respect  to a Class  of  Class A
Certificates  pursuant to clauses (i) and (ii) above and with respect to a Class
of Class B  Certificates  pursuant to clauses (iii) and (iv) above,  the amounts
shall be expressed as a dollar amount per Class A or Class B Certificate  (other
than the  Class A-R  Certificate)  with a $1,000  Denomination,  and as a dollar
amount per Class A-R Certificate with a $100 Denomination.

Within a  reasonable  period of time after the end of each  calendar  year,  the
Master Servicer shall furnish or cause to be furnished to each Person who at any
time  during the  calendar  year was the  Holder of a  Certificate  a  statement
containing  the  information  set forth in clauses (i) and (ii)(a)  above in the
case of a Class A  Certificateholder  and the  information  set forth in clauses
(iii) and (iv)(a)  above in the case of a Class B  Certificateholder  aggregated
for such calendar year or applicable  portion  thereof  during which such Person

to have been satisfied to the extent that substantially  comparable  information
shall be provided by the Master  Servicer  pursuant to any  requirements  of the
Code from time to time in force.

Prior to the  close  of  business  on the  third  Business  Day  preceding  each

any Paying Agent and the Seller (the  information  in such  statement to be made
available  to  Certificateholders  by the Master  Servicer  on written  request)
setting  forth the Class A  Distribution  Amount  with  respect to each Class of
Class A Certificates  and the Class B  Distribution  Amount with respect to each
Class of Class B Certificates.  The determination by the Master Servicer of such
amounts shall,  in the absence of obvious error, be  presumptively  deemed to be
correct for all purposes hereunder and the Trustee and the Paying Agent shall be
protected  in  relying  upon  the  same   without  any   independent   check  or
verification.

In addition to the reports  required  pursuant to this Section 4.04,  the Master
Servicer  shall make  available  upon  request to each Holder and each  proposed
transferee of a Class A-PO,  Class B-4, Class B-5 or Class B-6 Certificate  such
additional  information,  if any,  as may be  required  to permit  the  proposed
transfer to be effected pursuant to Rule 144A.

     Section 4.05   Reports to Mortgagors and the Internal Revenue Service.

The Master  Servicer  shall, in each year beginning after the Cut-Off Date, make
the  reports of  foreclosures  and  abandonments  of any  Mortgaged  Property as
required by Code Section 6050J. In order to facilitate  this reporting  process,
the Master Servicer shall request that each Servicer,  on or before January 15th
of each year, shall provide to the Internal Revenue Service,  with copies to the
Master Servicer, reports relating to each instance occurring during the previous
calendar  year in which such  Servicer (i) on behalf of the Trustee  acquires an
interest  in a  Mortgaged  Property  through  foreclosure  or  other  comparable
conversion in full or partial  satisfaction  of a Mortgage Loan serviced by such
Servicer, or (ii) knows or has reason to know that a Mortgaged Property has been
abandoned.  Reports from the Servicers shall be in form and substance sufficient
to meet the reporting  requirements  imposed by Code Section 6050J. In addition,
each Servicer shall provide the Master Servicer with  sufficient  information to
allow the Master  Servicer  to, for each year  ending  after the  Cut-Off  Date,
provide,  or cause to be  provided,  to the  Internal  Revenue  Service  and the
Mortgagors such  information as is required under Code Sections 6050H (regarding
payment of interest) and 6050P (regarding cancellation of indebtedness).

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

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

                                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, Class B-5 and Class B-6 Certificates, integral multiples of $1,000 in
excess thereof (except,  if necessary,  for one Certificate of each Class (other
than the Class  A-PO,  Class  A-R,  Class B-5 and Class B-6  Certificates)  that
evidences one Single  Certificate plus such additional  principal  portion 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-PO, A-R, 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 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.

            (c) 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.

            (d) 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.

            (e) 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
Certificate is an "insurance  company general  account" (as such term is defined
in Section V(e) of Prohibited  Transaction  Class Exemption 95-60 ("PTE 95-60"),
60 Fed. Reg. 35925 (July 12, 1995)),  (B) there is no Plan with respect to which
the  amount  of  such  general  account's   reserves  and  liabilities  for  the
contract(s)  held by or on behalf of such Plan and all other Plans maintained by
the same  employer (or  affiliate  thereof as defined in Section  V(a)(1) of PTE
95-60)  or by the same  employee  organization  exceeds  10% of the total of all
reserves and liabilities of such general account (as such amounts are determined
under Section I(a) of PTE 95-60) at the date of acquisition and (C) the purchase
and  holding of such Class B  Certificates  are covered by Sections I and III of
PTE 95-60 or (ii) the case of any such Class A-PO or Class 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.

            (f) No legal or  beneficial  interest  in all or any  portion of the
Class  A-R  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
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
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
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 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
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   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 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  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  Certificate  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  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  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 the Class A-R
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  Certificate,  and (ii) the
Master  Servicer  agrees to furnish to the Internal  Revenue  Service and to any
transferor  of the Class A-R  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 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.

            (g) 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.

            (h) 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.

            (i) 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 5.08   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 5.09   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,  other than any
loss, liability or expense incurred by reason of willful misfeasance,  bad faith
or gross  negligence  in the  performance  of his or its duties  hereunder or by
reason of reckless disregard of his or its obligations and duties hereunder. The
Seller,  the Master  Servicer and any of the directors,  officers,  employees or
agents of either may rely in good faith on any document of any kind which, PRIMA
FACIE, is properly  executed and submitted by any Person  respecting any matters
arising hereunder. Neither the Seller nor the Master Servicer shall be under any
obligation to appear in, prosecute or defend any legal action unless such action
is related  to its  respective  duties  under  this  Agreement  and which in its
opinion does not involve it in any expense or liability; PROVIDED, HOWEVER, that
the Seller or the  Master  Servicer  may in its  discretion  undertake  any such
action which it may deem  necessary or desirable  with respect to this Agreement
and the  rights  and  duties of the  parties  hereto  and the  interests  of the
Certificateholders  hereunder if the  Certificateholders  offer to the Seller or
the  Master  Servicer,  as the case may be,  reasonable  security  or  indemnity
against the costs,  expenses and  liabilities  which may be incurred  therein or
thereby.  In such  event,  the legal  expenses  and costs of such action and any
liability  resulting  therefrom shall be expenses,  costs and liabilities of the
Trust  Estate,  and the Seller or the Master  Servicer  shall be  entitled to be
reimbursed therefor out of the Certificate  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 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  trustee  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.

                                  ARTICLE VII

                                    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 or 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

                                  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:

               (iv) 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;

               (v) 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;

               (vi) 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;

               (vii)  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

                  a.    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 any  representation  for the
correctness  of the same.  The  Trustee  makes no any  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 the REMIC to federal,  state or local tax or cause the 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:

               (viii) 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;

               (ix) 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;

               (x) 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

               (xi) 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.

            (b) 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 a REMIC;
or (ii) cause the imposition of any federal,  state or local income,  prohibited
transaction,  contribution or other tax on either the 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
using a calendar  year as the taxable year for the REMIC and the accrual  method
of accounting;  (ii) in the first such federal tax return,  make, or cause to be
made, elections  satisfying the requirements of the REMIC Provisions,  on behalf
of the  Trust  Estate,  to treat the Trust  Estate  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 REMIC, as and when required to be provided to the Certificateholders, and
to the  Internal  Revenue  Service and any other  relevant  governmental  taxing
authority  in  accordance  with the REMIC  Provisions  and any other  applicable
federal,  state or local laws, including without limitation  information reports
relating to "original  issue  discount" and "market  discount" as defined in the
Code based upon the issue prices,  prepayment assumption and cash flows provided
by the Seller to the  Trustee  and  calculated  on a monthly  basis by using the
issue prices of the Certificates;  (iv) make available information necessary for
the  application  of any tax imposed on  transferors  of residual  interests  to
"disqualified  organizations"  (as  defined in the REMIC  Provisions);  (v) file
Forms SS-4 and 8811 and  respond to  inquiries  by  Certificateholders  or their
nominees concerning  information returns,  reports or tax returns; (vi) maintain
(or cause to be maintained by the Servicers) such records relating to the REMIC,
including but not limited to the income,  expenses,  individual  Mortgage  Loans
(including REO Mortgage Loans,  other assets and  liabilities of the REMIC,  and
the fair market value and adjusted  basis of the REMIC  property  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 the REMIC within the meaning of Code
Section 860D(a)(2) other than the interests  represented by the Class A-1, Class
A-2, Class A-3, Class A-4, Class A-5, 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; (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 Trust  Estate  or the REMIC to tax or (c) cause the Trust  Estate to
fail to qualify as a REMIC; (ix) exercise reasonable care not to allow the 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
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
REMIC,  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 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  Certificateholder  for such
purpose (or if the Master Servicer is not so permitted,  the Holder of the Class
A-R  Certificate  shall be the tax matters  person 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 the REMIC as described  above.  In the event that
the  Trustee  prepares  any of the  federal,  state and local tax returns of the
REMIC as described  above,  the Trustee  hereby  indemnifies  the Seller and the
Master Servicer for any losses, liabilities,  damages, claims or expenses of the
Seller or the Master Servicer  arising from the Trustee's  willful  misfeasance,
bad faith or negligence in connection with such preparation.

            (c) 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 Year 2000 Compliance.

The  Trustee  covenants  that it is  working to modify  its  computer  and 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.

                                   ARTICLE IX

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

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

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

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.

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

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

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

Percentage  Interest  evidenced by this Certificate in monthly  distributions to
the  Holders  of the Class A-PO  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 January 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-PO Certificates  required to be distributed
to Holders of the Class A-PO Certificates on such Distribution  Date, subject to
adjustment  in certain  events as  specified  in the  Agreement.  The Class A-PO
Certificates will not be entitled to distributions in respect of interest.

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

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

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

This  Certificate  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.

by the Master  Servicer or by a Paying Agent appointed by the Master Servicer by

representation letter, in the form as described in the Agreement, stating either

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

THIS CERTIFIES THAT  ____________________________ is the registered owner of the
Percentage  Interest  evidenced by this Certificate in monthly  distributions to
the  Holders  of the Class  B-5  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 January 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, 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-5  Distribution  Amount required to be distributed to Holders of the Class B-5
Certificates  on such  Distribution  Date,  subject  to  adjustment,  in certain
events,  as specified in the Agreement.  The pass-through  rate on the Class B-5
Certificates  applicable to each Distribution Date will be 6.000% 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-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. 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-5  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 an investment
letter in the form described in the Agreement and (ii) if such transfer is to be
made within  three  years from the later of (a) the date of initial  issuance of
the  Certificates  or (b) the last  date on which the  Seller  or any  affiliate
thereof was a Holder of the Certificates proposed to be transferred,  and unless
such transfer is made in reliance on Rule 144A of the Securities Act of 1933, as
amended,  the Trustee or the Seller may require the Holder to deliver an opinion
of counsel  acceptable to and in form and substance  satisfactory to the Trustee
and the Seller that such transfer is exempt (describing the applicable exemption
and the basis  therefor)  from or is being  made  pursuant  to the  registration
requirements  of the Securities  Act of 1933, as amended,  and of any applicable
statute of any state.  The Holder hereof desiring to effect such transfer shall,
and does  hereby  agree to,  indemnify  the  Trustee,  the  Seller,  the  Master
Servicer,  and any Paying  Agent  acting on behalf of the  Trustee  against  any
liability  that may  result if the  transfer  is not so exempt or is not made in
accordance  with  such  Federal  and state  laws.  In  connection  with any such
transfer, the Trustee will also require (i) a representation letter, in the form
as described in the  Agreement,  stating either (a) that the transferee is not a
Plan and is not  acting on  behalf  of a Plan or using  the  assets of a Plan to
effect  such  purchase  or (b) subject to certain  conditions  described  in the
Agreement,  that the source of funds used to  purchase  this  Certificate  is an
"insurance  company general  account," or (ii) if such transferee is a Plan, (a)
an opinion of counsel  acceptable to and in form and substance  satisfactory  to
the Trustee and the Seller  with  respect to certain  matters and (b) such other
documentation as the Seller or the Master Servicer may require,  as described in
the Agreement.

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

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

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

                      NORWEST ASSET SECURITIES CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATES
                                  SERIES 1999-3

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.

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

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

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

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 10.06 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

                        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

      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  governmental  plan, as defined in Section 3(32) of
      ERISA, subject to any federal,  state or local law which is, to a material
      extent,  similar  to  the  foregoing  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
      Certificate as they become due.

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

            (6) That the Purchaser  will not transfer the Class A-R  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 than a U.S.  Person (a "Non-U.S.  Person")  that holds the Class A-R
      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 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  Certificate  will not be disregarded for federal income tax
      purposes.  "U.S. Person" means a citizen or resident of the United States,
      a corporation,  partnership  (except to the extent  provided in applicable
      Treasury regulations) or other entity created or organized in or under the
      laws of the United States or any political  subdivision thereof, an estate
      that is subject to U.S. federal income tax regardless of the source of its
      income or a trust if a court within the United  States is able to exercise
      primary supervision over the administration of such trust, and one or more
      such U.S. Persons have the authority to control all substantial  decisions
      of  such  trust  (or,  to  the  extent  provided  in  applicable  Treasury
      regulations,  certain  trusts in  existence  on August 20,  1996 which are
      eligible to elect to be treated as U.S. Persons).

            (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 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.

The undersigned (the "Purchaser")  proposes to purchase Norwest Asset Securities

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 January 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
"Master Servicer") and First Union National Bank, as trustee (the "Trustee"), of
Norwest Asset Securities Corporation Mortgage Pass-Through Certificates,  Series
1999-3.

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:

            (a) The Purchaser is duly  organized,  validly  existing and in good
standing under the laws of the jurisdiction in which the Purchaser is organized,
is authorized to invest in the Class [A-PO][B-4][B-5][B-6]  Certificates, and to
enter into this Agreement, and duly executed and delivered this Agreement.

            (b) The  Purchaser  is  acquiring  the  Class  [A-PO][B-4][B-5][B-6]
Certificates  for its  own  account  as  principal  and  not  with a view to the
distribution thereof, in whole or in part.

[(c) The  Purchaser  has  knowledge  of financial  and  business  matters and is
capable  of  evaluating  the  merits  and  risks of an  investment  in the Class
[A-PO][B-4][B-5][B-6]  Certificates;  the Purchaser has sought such  accounting,
legal  and tax  advice  as it has  considered  necessary  to  make  an  informed
investment  decision;  and the Purchaser is able to bear the economic risk of an
investment  in the Class  [A-PO][B-4][B-5][B-6]  Certificates  and can  afford a
complete loss of such investment.]

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

            (d) The  Purchaser  confirms that (a) it has received and reviewed a
copy of the Private Placement  Memorandum dated __________ __, 19__, relating to
the Class  [A-PO][B-4][B-5][B-6]  Certificates  and  reviewed,  to the extent it
deemed appropriate,  the documents attached thereto or incorporated by reference
therein, (b) it has had the opportunity to ask questions of, and receive answers
from the Seller concerning the Class [A-PO][B-4][B-5][B-6]  Certificates and all
matters  relating  thereto,  and obtain any  additional  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  without  unreasonable
effort or expense and (c) it has undertaken its own independent  analysis of the
investment in the Class [A-PO][B-4][B-5][B-6]  Certificates.  The Purchaser will
not use or disclose any  information it receives in connection with its purchase
of the Class [A-PO][B-4][B-5][B-6]  Certificates other than in connection with a
subsequent sale of 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
behalf of a Plan, or a person  utilizing the assets of a Plan or (ii) [for Class
[B-4][B-5][B-6] Certificates only] if the Purchaser is an insurance company, (A)
the source of funds used to purchase the Class [B-4][B-5][B-6] Certificate is an
"insurance  company general account" (as such term is defined in Section V(e) of
Prohibited  Transaction Class Exemption 95-60 ("PTE 95-60"),  60 Fed. Reg. 35925
(July 12,  1995),  (B) there is no Plan with respect to which the amount of such
general  account's  reserves and liabilities  for the contract(s)  held by or on
behalf of such Plan and all other  Plans  maintained  by the same  employer  (or
affiliate  thereof as  defined  in Section  V(a)(1) of PTE 95-60) or by the same
employee  organization  exceeds 10% of the total of all reserves and liabilities
of such general  account (as such amounts are  determined  under Section I(a) of
PTE 95-60) at the date of  acquisition  and (C) the purchase and holding of such
Class  [B-4][B-5][B-6]  Certificates  are  covered by  Sections I and III of PTE
95-60  or  (iii)  the  Purchaser  has  provided  (a) a  "Benefit  Plan  Opinion"
satisfactory  to the  Seller 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 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 January 28, 1992
of the Federal Financial Institutions Examination Council and the April 15, 1994
Interim  Revision  thereto as adopted by the OCC, FRB,  FDIC, OTS and NCUA (with
modifications  as  applicable),  as  appropriate,  other  applicable  investment
authority,  rules, supervisory policies and guidelines of these agencies and, to
the extent  appropriate,  state banking  authorities  and has concluded that its
purchase  of  the  Class  [A-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.

SPECIAL SERVICING PROCEDURES

            SECTION 14.01     Reports and Notices

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

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

               (ii) Prior to the  Commencement of Foreclosure in connection with
      any Mortgage Loan, the Company shall cause (to the extent that the Company
      as Master  Servicer is granted  such  authority  in the related  Servicing
      Agreement)  the 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 14.02     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 14.03     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 14.04     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 XV

COLLATERAL FUND; SECURITY INTEREST

            SECTION 15.01     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  1999-3.  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 15.02     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 15.03     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
