ITEM 5.     Other Events

On August 27, 1999, Norwest Asset Securities Corporation, a Delaware corporation
(the "Registrant"),  sold Mortgage  Pass-Through  Certificates,  Series 1999-22,
Class  A-1,  Class  A-R,  Class  B-1,  Class  B-2 and  Class  B-3 (the  "Offered
Certificates"),    having   an   aggregate   original   principal   balance   of
$196,605,100.00  The Offered  Certificates were issued pursuant to a Pooling and
Servicing Agreement, dated as of August 27, 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  1999-22,  Class A-PO  Certificates,  having an  aggregate
initial principal  balance of $2,424,758.59,  and Class B-4, Class B-5 and Class
B-6 Certificates, having an aggregate initial principal balance of $1,000,990.55
(the  "Private  Class  B  Certificates"   and,  together  with  the  Class  A-PO
Certificates and the Offered Certificates, the "Certificates"), were also issued
pursuant to the Agreement.

As of the date of  initial  issuance,  the  Offered  Certificates  evidenced  an
approximate  98.29%  undivided  interest in a trust fund (the  "Trust  Estate"),
consisting principally of a pool of fixed interest rate,  conventional,  monthly
pay,  fully-amortizing,  one-to  four-family  residential  first mortgage loans,
other than the Fixed  Retained  Yield (as defined in the  Agreement),  which may
include loans secured by shares issued by cooperative housing corporations.  The
remaining  undivided  interests in the Trust  Estate are  evidenced by the Class
A-PO and Private  Class B  Certificates.  Distributions  on the Private  Class B
Certificates are  subordinated to distributions on the Offered  Certificates and
the Class A-PO Certificates.

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

An election will be made to treat the Trust Estate as a REMIC for federal income
tax purposes (the  "REMIC").  The Class A-1,  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.

                                   DEFINITIONS

SECTION 1.01   DEFINITIONS.

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

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

               Adjusted Pool Amount:  With respect to any Distribution Date, the
Cut-Off Date Aggregate  Principal Balance of the Mortgage Loans minus the sum of
(i) all  amounts in respect of  principal  received  in respect of the  Mortgage
Loans  (including,  without  limitation,  amounts received as Monthly  Payments,
Periodic Advances,  Unscheduled  Principal  Receipts and Substitution  Principal
Amounts) and  distributed to Holders of the  Certificates  on such  Distribution
Date and all prior  Distribution  Dates and (ii) the  principal  portion  of all
Realized  Losses (other than Debt Service  Reductions)  incurred on the Mortgage
Loans  from  the  Cut-Off  Date  through  the end of the  month  preceding  such
Distribution Date.

               Adjusted   Pool  Amount  (PO   Portion):   With  respect  to  any
Distribution Date, the sum of the amounts,  calculated as follows,  with respect
to all Outstanding  Mortgage Loans:  the product of (i) the PO Fraction for each
such  Mortgage  Loan and (ii) the  remainder of (A) the Cut-Off  Date  Principal
Balance of such Mortgage Loan minus (B) the sum of (x) all amounts in respect of
principal  received  in  respect  of  such  Mortgage  Loan  (including,  without
limitation, amounts received as Monthly Payments, Periodic Advances, Unscheduled
Principal  Receipts  and  Substitution  Principal  Amounts) and  distributed  to
Holders of the Certificates on such Distribution Date and all prior Distribution
Dates and (y) the  principal  portion of any  Realized  Loss  (other than a Debt
Service Reduction)  incurred on such Mortgage Loan from the Cut-Off Date through
the end of the month preceding such Distribution Date.

               Adjusted Principal  Balance:  As to any Distribution Date and any
Class of Class B Certificates, the greater of (A) zero and (B) (i) the Principal
Balance  of such Class with  respect  to such  Distribution  Date minus (ii) the
Adjustment Amount for such Distribution Date less the Principal Balances for any
Classes of Class B Certificates with higher numerical designations.

               Adjustment  Amount:  For any  Distribution  Date,  the difference

                          CONVEYANCE OF MORTGAGE LOANS;
                      ORIGINAL ISSUANCE OF THE CERTIFICATES

SECTION 2.01   CONVEYANCE OF MORTGAGE LOANS.

               The Seller,  concurrently with the execution and delivery hereof,
does hereby  assign to the Trustee,  without  recourse all the right,  title and
interest of the Seller in and to (a) the Trust  Estate,  including  all interest
(other than the portion,  if any,  representing  the Fixed  Retained  Yield) and
principal  received by the Seller on or with respect to the Mortgage Loans after
the Cut-Off Date (and including scheduled payments of principal and interest due
after the Cut-Off  Date but received by the Seller on or before the Cut-Off Date
and Unscheduled  Principal Receipts received or applied on the Cut-Off Date, but
not including payments of principal and interest due on the Mortgage Loans on or
before the Cut-Off Date), (b) the Insurance Policies, (c) the obligations of the
Servicers under the Servicing Agreements with respect to the Mortgage Loans, (d)
all of the  Seller's  right,  title and interest in and to each  Mortgage  100SM
Pledge  Agreement,  each Parent  Power(R)  Guaranty and Security  Agreement  for
Securities  Account and each Parent Power(R) Guaranty  Agreement for Real Estate
with respect to each MLCC  Additional  Collateral  Mortgage Loan, (e) all of the
Seller's  right,  title  and  interest  in and to each  Dual  Collateral  Pledge
Agreement with respect to each NOVUS Additional Collateral Mortgage Loan and (f)
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.

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

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

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

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

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

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

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

               (b) The Seller hereby represents  and warrants to the Trustee for
the benefit of  Certificateholders  that,  as of the date of  execution  of this
Agreement,  with respect to the Mortgage  Loans,  or each Mortgage  Loan, as the
case may be:

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

                      (ii)  Immediately  prior to the  transfer  and  assignment
        contemplated  herein,  the  Seller  was the sole owner and holder of the
        Mortgage Loan free and clear of any and all liens,  pledges,  charges or
        security  interests  of any nature and has full right and  authority  to
        sell and assign the same;

                      (iii) The Mortgage is a valid,  subsisting and enforceable
        first lien on the property therein described, and the Mortgaged Property
        is free and clear of all encumbrances and liens having priority over the
        first lien of the  Mortgage  except for liens for real estate  taxes and
        special  assessments  not yet due and  payable  and  liens or  interests
        arising  under  or as a result  of any  federal,  state  or  local  law,
        regulation  or  ordinance  relating  to  hazardous  wastes or  hazardous
        substances,  and, if the  related  Mortgaged  Property is a  condominium
        unit,  any lien for common  charges  permitted by statute or  homeowners
        association fees; and if the Mortgaged  Property consists of shares of a
        cooperative  housing  corporation,  any  lien  for  amounts  due  to the
        cooperative housing corporation for unpaid assessments or charges or any
        lien of any assignment of rents or maintenance  expenses  secured by the
        real property  owned by the  cooperative  housing  corporation;  and any
        security agreement,  chattel mortgage or equivalent document related to,
        and  delivered  to the Trustee or to the  Custodian  with,  any Mortgage
        establishes  in the  Seller a valid  and  subsisting  first  lien on the
        property  described  therein  and the  Seller has full right to sell and
        assign the same to the Trustee;

                      (iv)  Neither  the  Seller  nor any  prior  holder  of the
        Mortgage or the related  Mortgage  Note has modified the Mortgage or the
        related Mortgage Note in any material  respect,  satisfied,  canceled or
        subordinated  the Mortgage in whole or in part,  released the  Mortgaged
        Property in whole or in part from the lien of the Mortgage,  or executed
        any instrument of release,  cancellation,  modification or satisfaction,
        except in each case as is  reflected  in an  agreement  delivered to the
        Trustee or the Custodian pursuant to Section 2.01;

                      (v)  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;

                      (vi) 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;

                      (vii)  The  Mortgaged  Property  is free and  clear of all
        mechanics'  and  materialmen's  liens or liens  in the  nature  thereof;
        provided,  however,  that this warranty shall be deemed not to have been
        made at the time of the initial  issuance of the Certificates if a title
        policy  affording,  in substance,  the same protection  afforded by this
        warranty is furnished to the Trustee by the Seller;

                      (viii)  Except for Mortgage  Loans secured by Co-op Shares
        and  Mortgage  Loans  secured  by  residential   long-term  leases,  the
        Mortgaged Property consists of a fee simple estate in real property; all
        of the  improvements  which are included for the purpose of  determining

        improvements  on  adjoining   properties  encroach  upon  the  Mortgaged
        Property  (unless  insured  against  under the related  title  insurance
        policy);  and to the  best  of the  Seller's  knowledge,  the  Mortgaged

        Date;

                      (xii) The Mortgage  Note,  the related  Mortgage and other
        agreements executed in connection therewith are genuine, and each is the
        legal, valid and binding obligation of the maker thereof, enforceable in
        accordance with its terms,  except as such enforcement may be limited by
        bankruptcy,  insolvency,  reorganization or other similar laws affecting
        the  enforcement  of creditors'  rights  generally and by general equity
        principles  (regardless  of whether such  enforcement is considered in a
        proceeding  in  equity  or at law);  and,  to the  best of the  Seller's
        knowledge,  all parties to the Mortgage  Note and the Mortgage had legal
        capacity to execute the Mortgage Note and the Mortgage and each Mortgage
        Note and Mortgage has been duly and properly executed by the Mortgagor;

                      (xiii) Any and all  requirements of any federal,  state or
        local  law  with  respect  to  the  origination  of the  Mortgage  Loans
        including, without limitation,  truth-in-lending, real estate settlement
        procedures,  consumer  credit  protection,  equal credit  opportunity or
        disclosure  laws  applicable  to the Mortgage  Loans have been  complied
        with;

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

                      (xvi) The Mortgaged  Property  securing each Mortgage Loan
        is insured by an insurer  acceptable  to FNMA or FHLMC  against  loss by
        fire and such hazards as are covered under a standard  extended coverage
        endorsement,  in an amount  which is not less than the lesser of 100% of
        the  insurable  value  of the  Mortgaged  Property  and the  outstanding
        principal  balance of the Mortgage  Loan,  but in no event less than the
        minimum amount necessary to fully compensate for any damage or loss on a
        replacement cost basis; if the Mortgaged Property is a condominium unit,
        it is included  under the coverage  afforded by a blanket policy for the
        project;  if upon  origination of the Mortgage Loan, the improvements on
        the  Mortgaged  Property  were  in an  area  identified  in the  Federal
        Register by the Federal  Emergency  Management  Agency as having special
        flood hazards,  a flood insurance policy meeting the requirements of the
        current guidelines of the Federal Insurance  Administration is in effect
        with a generally acceptable insurance carrier, in an amount representing
        coverage  not less  than  the  least  of (A) the  outstanding  principal
        balance  of the  Mortgage  Loan,  (B) the  full  insurable  value of the
        Mortgaged  Property and (C) the maximum  amount of  insurance  which was
        available  under the National  Flood  Insurance Act of 1968, as amended;
        and each Mortgage  obligates  the  Mortgagor  thereunder to maintain all
        such insurance at the Mortgagor's cost and expense;

                      (xvii) To the best of the Seller's knowledge,  there is no
        default,  breach,  violation or event of acceleration existing under the
        Mortgage  or the  related  Mortgage  Note and no event  which,  with the
        passage of time or with notice and the  expiration  of any grace or cure
        period,  would  constitute  a  default,  breach,  violation  or event of
        acceleration;  the Seller has not waived any default,  breach, violation
        or  event  of  acceleration;  and no  foreclosure  action  is  currently
        threatened or has been commenced with respect to the Mortgage Loan;

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

                      (xix) Each Mortgage  Note is payable in monthly  payments,
        resulting in complete  amortization  of the Mortgage Loan over a term of
        not more than 180 months;

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

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

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

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

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

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

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

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

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

               (c)Upon discovery by either the Seller, the Master Servicer,  the
Trustee or the Custodian that any of the  representations and warranties made in
subsection (b) above is not accurate (referred to herein as a "breach") and that
such  breach   materially   and   adversely   affects  the   interests   of  the
Certificateholders  in the related  Mortgage  Loan, the party  discovering  such
breach shall give prompt  written  notice to the other  parties  (any  Custodian
being so obligated under a Custodial  Agreement).  Within 60 days of the earlier
of its  discovery or its receipt of notice of any such breach,  the Seller shall
cure such breach in all  material  respects or shall either (i)  repurchase  the
Mortgage Loan or any property  acquired in respect thereof from the Trust Estate
at a price equal to (A) 100% of the unpaid  principal  balance of such  Mortgage
Loan  plus (B)  accrued  interest  at the Net  Mortgage  Interest  Rate for such
Mortgage  Loan through the last day of the month in which such  repurchase  took
place or (ii) if within  two years of the  Startup  Day,  or such  other  period
permitted by the REMIC  Provisions,  substitute  for such  Mortgage  Loan in the
manner described in Section 2.02. The purchase price of any repurchase described
in this paragraph and the Substitution  Principal  Amount,  if any, plus accrued
interest  thereon and the other amounts  referred to in Section  2.02,  shall be
deposited  in the  Certificate  Account.  It is  understood  and agreed that the
obligation of the Seller to  repurchase  or substitute  for any Mortgage Loan or
property  as to  which  such a  breach  has  occurred  and is  continuing  shall
constitute   the   sole   remedy    respecting   such   breach    available   to
Certificateholders  or the  Trustee  on behalf of  Certificateholders,  and such
obligation shall survive until termination of the Trust Estate hereunder.

SECTION 2.04   EXECUTION AND DELIVERY OF CERTIFICATES.

               The Trustee  acknowledges  the  assignment  to it of the Mortgage
Loans and the delivery of the Owner Mortgage Loan Files to it, and, concurrently
with such  delivery,  has  executed  and  delivered  to or upon the order of the
Seller,  in exchange  for the  Mortgage  Loans  together  with all other  assets
included  in the  definition  of  "Trust  Estate,"  receipt  of which is  hereby
acknowledged,  Certificates in authorized denominations which evidence ownership
of the entire Trust Estate.

SECTION 2.05   DESIGNATION OF CERTIFICATES; DESIGNATION OF
               STARTUP DAY AND LATEST POSSIBLE MATURITY DATE.

                 ADMINISTRATION OF THE TRUST ESTATE: SERVICING
                              OF THE MORTGAGE LOANS

SECTION 3.01   CERTIFICATE ACCOUNT.

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

               (b) The  Master  Servicer  shall  deposit  into  the  Certificate
Account  on the day of  receipt  thereof  all  amounts  received  by it from any
Servicer pursuant to any of the Servicing Agreements, any amounts received by it
upon the sale of any (A) MLCC Additional Collateral pursuant to the terms of the
Mortgage  100SM  Pledge  Agreement,  the Parent  Power(R)  Guaranty and Security
Agreement for Securities  Account or the Parent Power(R) Guaranty  Agreement for
Real Estate,  or (B) NOVUS  Additional  Collateral  pursuant to the terms of the
Dual Collateral  Pledge Agreement or any amounts  received  pursuant to the MLCC
Surety Bond or the NOVUS Surety Bond, and shall,  in addition,  deposit into the
Certificate  Account the following amounts,  in the case of amounts specified in
clause  (i),  not later than the  Distribution  Date on which such  amounts  are
required to be distributed to Certificateholders and, in the case of the amounts
specified in clause (ii), not later than the Business Day next following the day
of receipt and posting by the Master Servicer:

                      (i) Periodic  Advances pursuant to Section 3.03(a) made by
        the  Master  Servicer  or the  Trustee,  if any and any  amounts  deemed
        received by the Master Servicer pursuant to Section 3.01(d); and

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

               (c) The Master  Servicer shall cause the funds in the Certificate
Account to be invested in Eligible  Investments.  No such  Eligible  Investments
will be sold or  disposed  of at a gain  prior to  maturity  unless  the  Master
Servicer has received an Opinion of Counsel or other evidence satisfactory to it
that such sale or  disposition  will not cause the Trust Estate to be subject to
Prohibited Transactions Tax, otherwise subject the Trust Estate to tax, or cause
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.

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

SECTION 3.02   PERMITTED WITHDRAWALS FROM THE CERTIFICATE ACCOUNT.

               (a) The Master Servicer may, from time to time, make  withdrawals

        Mortgage Loan to the Master Servicer;

        or  reimbursable to it pursuant to Section  3.03(c),  3.03(d) or 6.03 or

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

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

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

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

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

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

SECTION 3.03   ADVANCES BY MASTER SERVICER AND TRUSTEE.

               (a) In the  event an Other  Servicer  fails to make any  required
Periodic  Advances of principal  and interest on a Mortgage  Loan as required by
the related Other Servicing  Agreement prior to the Distribution  Date occurring
in the month during  which such  Periodic  Advance is due,  the Master  Servicer
shall make Periodic  Advances to the extent  provided  hereby.  In 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.

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

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

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

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

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

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

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

SECTION 3.05   REPORTS TO THE TRUSTEE;
               ANNUAL COMPLIANCE STATEMENTS.

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

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

SECTION 3.06   TITLE, MANAGEMENT AND DISPOSITION OF ANY
               REO MORTGAGE LOAN.

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

SECTION 3.07   AMENDMENTS TO SERVICING AGREEMENTS,
               MODIFICATION OF STANDARD PROVISIONS.

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

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

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

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

SECTION 3.08   OVERSIGHT OF SERVICING.

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

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

               The Master Servicer may enter into a special servicing  agreement
with an unaffiliated  holder of 100%  Percentage  Interest of a Class of Class B
Certificates or a holder of a class of securities  representing interests in the
Class  B   Certificates   and/or  other   subordinated   mortgage   pass-through
certificates, such agreement to be substantially in the form of Exhibit M hereto
or  subject  to each  Rating  Agency's  acknowledgment  that the  ratings of the
Certificates in effect  immediately prior to the entering into of such agreement
would not be qualified,  downgraded or withdrawn and the Certificates  would not
be placed on credit review status (except for possible upgrading) as a result of
such agreement.  Any such agreement may contain  provisions  whereby such holder
may instruct the Master  Servicer to instruct a Servicer to the extent  provided
in  the  applicable   Servicing  Agreement  to  commence  or  delay  foreclosure
proceedings  with  respect  to  delinquent   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   1934 ACT REPORTS.

               The Master  Servicer  shall,  on behalf of the  Seller,  make all
filings  required  to be  made  by  the  Seller  with  respect  to the  Class  A
Certificates  (other than the Class A-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.

        the Class B-3 Unpaid Interest Shortfall;

                      thirteenth,  to the Class B-3 Certificates in an amount up

        above;

                      seventeenth, to the Class B-5 Certificates in an amount up
        to the  Interest  Accrual  Amount  for the Class B-5  Certificates  with
        respect to such Distribution Date;

                      eighteenth,  to the Class B-5 Certificates in an amount up

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

        up to the Class B-6 Optimal Principal Amount;  provided,  however,  that
        the amount distributable to the Class B-6 Certificates  pursuant to this
        Paragraph  twenty-second  will be reduced by the  amount,  if any,  that
        would have been  distributable to the Class B-6  Certificates  hereunder
        used to pay the 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 outstanding Principal Balances.

               (b)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:

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

                      second, to the Class A-1 Certificates, until the Principal
        Balance thereof has been reduced to zero.

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

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

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

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

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

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

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

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

               (e) 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
Class of Class B Certificates.

               In the event that,  on any  Distribution  Date prior to the Final
Distribution  Date,  the Principal  Balance of any Class of Class A Certificates
(other than the Class A-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).

               (f) The  Paying Agent (or if no Paying  Agent is appointed by the
Master  Servicer,  the Master  Servicer)  shall withhold or cause to be withheld
such  amounts  as may be  required  by  the  Code  (giving  full  effect  to any
exemptions from withholding and related certifications  required to be furnished
by  Certificateholders  and any  reductions  to  withholding  by  virtue  of any
bilateral tax treaties and any applicable certification required to be furnished
by  Certificateholders  with respect  thereto) from  distributions to be made to
Persons other than U.S. Persons ("Non-U.S.  Persons"). Amounts withheld pursuant
to this  Section  4.01(f)  shall be treated as having  been  distributed  to the
related  Certificateholder for all purposes of this Agreement.  For the purposes
of this  paragraph,  a "U.S.  Person"  is a citizen  or  resident  of the United
States,  a corporation  or  partnership  (unless,  in the case of a partnership,
Treasury regulations are adopted that provide otherwise) created or organized in
or under the laws of the United  States,  any state  thereof or the  District of
Columbia,  including  an entity  treated as a  corporation  or  partnership  for
federal income tax purposes,  an estate whose income is subject to United States
federal  income tax  regardless of its source,  or a trust if a court within the
United States is able to exercise primary supervision over the administration of
such trust,  and one or more such U.S. Persons have the authority to control all
substantial  decisions of such trust (or, to the extent  provided in  applicable
Treasury  regulations,  certain trusts in existence on August 20, 1996 which are
eligible to elect to be treated as U.S. Persons).

SECTION 4.02   ALLOCATION OF REALIZED LOSSES.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

SECTION 4.03   PAYING AGENT.

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

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

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

                      (i) hold all amounts remitted to it by the Master Servicer
        for  distribution  to  Certificateholders  in trust for the  benefit  of
        Certificateholders    until   such    amounts   are    distributed    to
        Certificateholders or otherwise disposed of as herein provided;

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

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

               (b) The  Paying  Agent  shall  establish  and  maintain a Payment
Account,  which shall be a separate  trust account and an Eligible  Account,  in
which  the  Master  Servicer  shall  cause  to be  deposited  from  funds in the
Certificate Account or, to the extent required hereunder, from its own funds (i)
at or before  10:00 a.m.,  New York time,  on the Business  Day  preceding  each
Distribution Date, by wire transfer of immediately available funds, any Periodic
Advance for such  Distribution  Date,  pursuant  to Section  3.03 and (ii) at or

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.

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-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.

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

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

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

               No service  charge  shall be made for any transfer or exchange of
Certificates,  but the Trustee or the Certificate  Registrar may require payment
of a sum sufficient to cover any tax or governmental  charge that may be imposed
in connection with any transfer or exchange of Certificates.

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

               (b) No transfer of a Class  A-PO,  Class B-4,  Class B-5 or Class
B-6  Certificate  shall be made  unless  the  registration  requirements  of the
Securities Act of 1933, as amended, and any applicable State securities laws are
complied  with,  or such transfer is exempt from the  registration  requirements
under said Act and laws.  In the event that a transfer is to be made in reliance
upon an  exemption  from said Act or laws,  (i) unless such  transfer is made in
reliance on Rule 144A,  the Trustee or the Seller may, if such transfer is to be
made within  three years after the later of (i) the date of the initial  sale of
Certificates or (ii) the last date on which the Seller or any affiliate  thereof
was a Holder of the  Certificates  proposed to be  transferred,  require a Class
A-PO, Class B-4, Class B-5 or Class B-6  Certificateholder  to deliver a written
Opinion of Counsel  acceptable to and in form and substance  satisfactory to the
Trustee and the Seller, to the effect that such transfer may be made pursuant to
an exemption,  describing the applicable exemption and the basis therefor,  from
said Act and laws or is being made pursuant to said Act and laws,  which Opinion
of  Counsel  shall not be an expense  of the  Trustee,  the Seller or the Master
Servicer,  and (ii) the  Trustee  shall  require the  transferee  (other than an
affiliate of the Seller on the Closing Date) to execute an investment  letter in
the form of Exhibit J hereto  certifying to the Seller and the Trustee the facts
surrounding such transfer,  which  investment  letter shall not be an expense of
the  Trustee,  the Seller or the Master  Servicer.  The Holder of a Class  A-PO,
Class B-4, Class B-5 or Class B-6  Certificate  desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee,  the Seller,  the Master
Servicer  and any  Paying  Agent  acting on behalf of the  Trustee  against  any
liability  that may  result if the  transfer  is not so exempt or is not made in
accordance with such federal and state laws.  Neither the Seller nor the Trustee
is under an obligation to register the Class A-PO, Class B-4, Class B-5 or Class
B-6 Certificates under said Act or any other securities law.

               (c) No transfer of a Class A-PO or Class B  Certificate  shall be
made (other than the transfer of the Class A-PO  Certificates to an affiliate of
the Seller on the Closing  Date)  unless the  Trustee and the Seller  shall have
received (i) a representation  letter from the transferee in the form of Exhibit
J  hereto,  in the case of a Class  A-PO,  Class  B-4,  Class  B-5 or Class  B-6
Certificate,  or in the form of  Exhibit K hereto,  in the case of a Class  B-1,
Class  B-2 or  Class  B-3  Certificate,  to the  effect  that  either  (a)  such
transferee  is not an  employee  benefit  plan or other  retirement  arrangement
subject to Title I of ERISA or Code Section  4975,  or a  governmental  plan, as
defined in Section  3(32) of ERISA,  subject to any federal,  state or local law
("Similar  Law")  which  is  to a  material  extent  similar  to  the  foregoing
provisions  of ERISA or the Code  (collectively,  a "Plan")  and is not a person
acting on behalf of or using the assets of any such Plan,  which  representation
letter shall not be an expense of the Trustee, the Seller or the Master Servicer
or (b) with respect to the Class B Certificates  only, if such  transferee is an
insurance  company,  (A) the  source  of  funds  used to  purchase  the  Class B
Certificate is an "insurance  company general  account" (as such term is defined
in Section V(e) of Prohibited  Transaction  Class Exemption 95-60 ("PTE 95-60"),
60 Fed. Reg. 35925 (July 12, 1995)),  (B) there is no Plan with respect to which
the  amount  of  such  general  account's   reserves  and  liabilities  for  the
contract(s)  held by or on behalf of such Plan and all other Plans maintained by
the same  employer (or  affiliate  thereof as defined in Section  V(a)(1) of PTE
95-60)  or by the same  employee  organization  exceeds  10% of the total of all
reserves and liabilities of such general account (as such amounts are determined
under Section I(a) of PTE 95-60) at the date of acquisition and (C) the purchase
and  holding of such Class B  Certificates  are covered by Sections I and III of
PTE  95-60  or (ii) in the case of any such  Class  A-PO or Class B  Certificate
presented for registration in the name of a Plan, or a trustee of any such Plan,
(A) an Opinion  of Counsel  satisfactory  to the  Trustee  and the Seller to the
effect that the  purchase  or holding of such Class A-PO or Class B  Certificate
will not  result  in the  assets of the Trust  Estate  being  deemed to be "plan
assets" and subject to the prohibited  transaction provisions of ERISA, the Code
or  Similar  Law and will not  subject  the  Trustee,  the  Seller or the Master
Servicer to any  obligation in addition to those  undertaken in this  Agreement,
which Opinion of Counsel  shall not be an expense of the Trustee,  the Seller or
the  Master  Servicer  and  (B)  such  other  opinions  of  counsel,   officer's
certificates  and agreements as the Seller or the Master Servicer may require in
connection with such transfer, which opinions of counsel, officers' certificates
and agreements shall not be an expense of the Trustee,  the Seller or the Master
Servicer.  The Class A-PO and Class B Certificates shall bear a legend referring
to the foregoing restrictions contained in this paragraph.

               (d) No legal or beneficial  interest in all or any portion of the
Class  A-R  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.

               (a) If the Trustee is not acting as  Certificate  Registrar,  the
Certificate  Registrar  shall  furnish or cause to be  furnished to the Trustee,
within 15 days after  receipt by the  Certificate  Registrar of a request by the
Trustee in writing, a list, in such form as the Trustee may reasonably  require,
of the names and  addresses  of the  Certificateholders  of each Class as of the
most recent Record Date.

               (b) If five or more  Certificateholders  (hereinafter referred to
as "applicants")  apply in writing to the Trustee,  and such application  states
that the applicants  desire to communicate  with other  Certificateholders  with
respect to their rights under this  Agreement or under the  Certificates  and is
accompanied  by a copy of the  communication  which such  applicants  propose to
transmit,  then the Trustee  shall,  within five  Business  Days  following  the
receipt  of such  application,  afford  such  applicants  access  during  normal
business  hours  to the  most  recent  list  of  Certificateholders  held by the
Trustee. If such a list is as of the date more than 90 days prior to the date of
receipt of such  applicants'  request  and the  Trustee  is not the  Certificate
Registrar,  the Trustee shall promptly request from the Certificate  Registrar a
current  list as  provided  in  paragraph  (a)  hereof,  and shall  afford  such
applicants access to such list promptly upon receipt.

               (c)  Every   Certificateholder,   by  receiving   and  holding  a
Certificate,  agrees  with the  Seller,  the Master  Servicer,  the  Certificate
Registrar  and the Trustee that  neither the Seller,  the Master  Servicer,  the
Certificate Registrar nor the Trustee shall be held accountable by reason of the
disclosure of any such  information  as to the names,  addresses and  Percentage
Interests of the  Certificateholders  hereunder,  regardless  of the source from
which such information was delivered.

SECTION 5.06   MAINTENANCE OF OFFICE OR AGENCY.

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

SECTION 5.07   DEFINITIVE CERTIFICATES.

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

SECTION 5.08   NOTICES TO CLEARING AGENCY.

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

                                   ARTICLE VI

                       THE SELLER AND THE MASTER SERVICER

SECTION 6.01 LIABILITY OF THE SELLER AND THE MASTER SERVICER.

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

SECTION 6.02 MERGER OR CONSOLIDATION OF THE SELLER OR THE MASTER SERVICER.

               Subject  to the  following  paragraph,  the Seller and the Master
Servicer each will keep in full effect its existence, rights and franchises as a
corporation  under the laws of the jurisdiction of its  incorporation,  and will
obtain and preserve its qualification to do business as a foreign corporation in
each  jurisdiction  in which  such  qualification  is or shall be  necessary  to
protect the validity and  enforceability of this Agreement,  the Certificates or
any of the  Mortgage  Loans and to  perform  its  respective  duties  under this
Agreement.

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

SECTION 6.03   LIMITATION ON LIABILITY OF THE SELLER,
               THE MASTER SERVICER AND OTHERS.

               Neither the Seller nor the Master Servicer nor any  subcontractor
nor any of the partners, directors, officers, employees or agents of any of them
shall be under any liability to the Trust Estate or the  Certificateholders  and
all such Persons shall be held  harmless for any action taken or for  refraining
from the taking of any action in good faith pursuant to this  Agreement,  or for
errors in judgment; provided, however, that this provision shall not protect any
such Person against any breach of warranties or  representations  made herein or
against  any  liability  which would  otherwise  be imposed by reason of willful
misfeasance,  bad faith or gross  negligence in the  performance of duties or by
reason of reckless  disregard of obligations and duties  hereunder.  The Seller,
the Master Servicer,  any  subcontractor,  and any partner,  director,  officer,
employee  or agent of any of them shall be entitled  to  indemnification  by the
Trust Estate and will be held  harmless  against any loss,  liability or expense
incurred in connection  with any legal action  relating to this Agreement or the
Certificates,  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 COVENANTS CONCERNING YEAR 2000 COMPLIANCE.

               The Master  Servicer  covenants  that it is working to modify its
computer  and other  systems  used in the  performance  of its  duties as Master
Servicer  for the  Certificates  to operate in a manner such that,  on and after
January 1, 2000, the Master  Servicer can perform its duties in accordance  with
the terms of this Agreement.

                                     DEFAULT

SECTION 7.01   EVENTS OF DEFAULT.

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

                      (i) any  failure by the Master  Servicer  (a) to remit any
        funds  to the  Paying  Agent  as  required  by  Section  4.03  or (b) to
        distribute or cause to be distributed to Certificateholders  any payment
        required  to be made by the  Master  Servicer  under  the  terms of this
        Agreement  which, in either case,  continues  unremedied for a period of
        three  business  days after the date upon which  written  notice of such
        failure, requiring the same to be remedied, shall have been given to the
        Master Servicer by the Trustee or to the Master Servicer and the Trustee
        by the holders of Certificates evidencing in the aggregate not less than
        25% of the aggregate Voting Interest represented by all Certificates; or

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

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

                      (iv) the Master  Servicer shall consent to the appointment
        of  a  trustee,  conservator,  receiver  or  liquidator  or  liquidating
        committee  in  any   bankruptcy,   insolvency,   readjustment  of  debt,
        marshaling of assets and liabilities,  voluntary  liquidation or similar
        proceedings of or relating to the Master Servicer,  or of or relating to
        all or substantially all of its property; or

                      (v)  the  Master  Servicer  shall  admit  in  writing  its
        inability to pay its debts generally as they become due, file a petition
        to  take   advantage  of  any  applicable   insolvency,   bankruptcy  or
        reorganization  statute,  make  an  assignment  for the  benefit  of its
        creditors or voluntarily suspend payment of its obligations;

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

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

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

SECTION 7.02   OTHER REMEDIES OF TRUSTEE.

               During the  continuance of any Event of Default,  so long as such
Event of Default shall not have been remedied,  the Trustee,  in addition to the
rights  specified  in Section  7.01,  shall  have the right,  in its own name as
trustee of an express  trust,  to take all actions now or hereafter  existing at
law, in equity or by statute to enforce its rights and  remedies  and to protect
the interests,  and enforce the rights and remedies,  of the  Certificateholders
(including the institution and prosecution of all judicial,  administrative  and
other  proceedings  and the  filing of  proofs  of claim and debt in  connection
therewith).  Except as otherwise expressly provided in this Agreement, no remedy
provided for by this Agreement shall be exclusive of any other remedy,  and each
and every remedy shall be cumulative  and in addition to any other remedy and no
delay or omission to exercise any right or remedy shall impair any such right or
remedy or shall be deemed to be a waiver of any Event of Default.

SECTION 7.03   DIRECTIONS BY CERTIFICATEHOLDERS AND
               DUTIES OF TRUSTEE DURING EVENT OF DEFAULT.

               During  the  continuance  of any  Event of  Default,  Holders  of
Certificates  evidencing  in the  aggregate  not less than 25% of the  aggregate
Voting Interest  represented by all Certificates may direct the time, method and
place of conducting any proceeding for any remedy  available to the Trustee,  or
exercising any trust or power conferred upon the Trustee,  under this Agreement;
provided,  however,  that the Trustee shall be under no obligation to pursue any
such  remedy,  or to exercise  any of the rights or powers  vested in it by this
agreement (including, without limitation, (i) the conducting or defending of any
administrative action or litigation hereunder or in relation hereto and (ii) the
terminating  of the Master  Servicer  from its  rights  and  duties as  servicer
hereunder) at the request, order or direction of any of the  Certificateholders,
unless such  Certificateholders  shall have  offered to the  Trustee  reasonable
security or indemnity  against the cost,  expenses and liabilities  which may be
incurred  therein  or  thereby  and,  provided  further,  that,  subject  to the
provisions  of  Section  8.01,  the  Trustee  shall have the right to decline to
follow any such  direction  if the  Trustee,  in  accordance  with an Opinion of
Counsel,  determines  that the action or proceeding so directed may not lawfully
be  taken  or if the  Trustee  in good  faith  determines  that  the  action  or
proceeding  so directed  would  involve it in personal  liability or be unjustly
prejudicial to the nonassenting Certificateholders.

SECTION 7.04   ACTION UPON CERTAIN FAILURES OF THE
               MASTER SERVICER AND UPON EVENT OF DEFAULT.

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

SECTION 7.05   TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

               When the Master Servicer receives notice of termination  pursuant
to Section 7.01 or the Trustee  receives the  resignation of the Master Servicer
evidenced by an Opinion of Counsel  pursuant to Section 6.04,  the Trustee shall
be the  successor  in all  respects to the Master  Servicer  in its  capacity as
master servicer under this Agreement and the  transactions set forth or provided
for  herein  and shall  have the  rights  and  powers  and be subject to all the
responsibilities,  duties and liabilities  relating thereto placed on the Master
Servicer  by the  terms  and  provisions  hereof  and in its  capacity  as  such
successor  shall have the same  limitation  of liability  herein  granted to the
Master  Servicer.  In the event  that the  Trustee is  succeeding  to the Master
Servicer as the Master Servicer, as compensation  therefor, the Trustee shall be
entitled to receive monthly such portion of the Master  Servicing Fee,  together
with  such  other  servicing  compensation  as is  agreed to at such time by the
Trustee and the Master Servicer, but in no event more than 25% thereof until the
date of final cessation of the Master Servicer's servicing activities hereunder.
Notwithstanding  the above, the Trustee may, if it shall be unwilling to so act,
or shall,  if it is unable to so act or to obtain a qualifying  bid as described
below,  appoint, or petition a court of competent  jurisdiction to appoint,  any
housing and home finance  institution,  bank or mortgage  servicing  institution
having a net worth of not less than $10,000,000 and meeting such other standards
for a successor servicer as are set forth herein, as the successor to the Master
Servicer hereunder in the assumption of all or any part of the responsibilities,
duties or liabilities of the Master Servicer hereunder;  provided, however, that
until  such a  successor  master  servicer  is  appointed  and has  assumed  the
responsibilities,  duties and liabilities of the Master Servicer hereunder,  the
Trustee  shall  continue  as the  successor  to the Master  Servicer as provided
above.  The compensation of any successor master servicer so appointed shall not
exceed the  compensation  specified  in Section  6.05  hereof.  In the event the
Trustee is  required  to solicit  bids as  provided  above,  the  Trustee  shall
solicit,   by  public   announcement,   bids  from   housing  and  home  finance
institutions,   banks  and   mortgage   servicing   institutions   meeting   the
qualifications  set forth in the  preceding  sentence  for the  purchase  of the
master  servicing  functions.  Such public  announcement  shall specify that the
successor  master  servicer  shall be  entitled to the full amount of the Master
Servicing Fee as compensation together with the other servicing  compensation in
the form of late reporting fees or otherwise as provided in Section 6.05. Within
30 days after any such public  announcement,  the Trustee  shall  negotiate  and
effect the sale,  transfer and  assignment  of the master  servicing  rights and
responsibilities  hereunder  to  the  qualified  party  submitting  the  highest
qualifying  bid.  The Trustee  shall deduct all costs and expenses of any public
announcement  and of any sale,  transfer and assignment of the servicing  rights
and  responsibilities  hereunder  from any sum  received by the Trustee from the
successor  to the  Master  Servicer  in  respect  of  such  sale,  transfer  and
assignment.  After such  deductions,  the remainder of such sum shall be paid by
the  Trustee  to the Master  Servicer  at the time of such  sale,  transfer  and
assignment to the Master  Servicer's  successor.  The Trustee and such successor
shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. The Master Servicer agrees to cooperate with the
Trustee and any successor  servicer in effecting the  termination  of the Master
Servicer's  servicing  responsibilities  and rights hereunder and shall promptly
provide  the Trustee or such  successor  master  servicer,  as  applicable,  all
documents  and  records  reasonably  requested  by it to enable it to assume the
Master  Servicer's  function  hereunder and shall  promptly also transfer to the
Trustee or such successor master servicer, as applicable, all amounts which then
have been or should have been deposited in the Certificate Account by the Master
Servicer or which are thereafter received by the Master Servicer with respect to
the Mortgage Loans.  Neither the Trustee nor any other successor master servicer
shall be deemed to be in default  hereunder by reason of any failure to make, or
any delay in making, any distribution hereunder or any portion thereof caused by
(i) the failure of the Master  Servicer to deliver,  or any delay in delivering,
cash, documents or records to it, or (ii) restrictions imposed by any regulatory
authority having jurisdiction over the Master Servicer. Notwithstanding anything
to the contrary contained in Section 7.01 above or this Section 7.05, the Master
Servicer shall retain all of its rights and responsibilities  hereunder,  and no
successor  (including  the Trustee)  shall succeed  thereto,  if the  assumption
thereof by such successor would cause the rating assigned to any Certificates to
be  revoked,  downgraded  or placed  on credit  review  status  (other  than for
possible  upgrading) by either  Rating  Agency and the retention  thereof by the
Master Servicer would avert such revocation, downgrading or review.

SECTION 7.06   NOTIFICATION TO CERTIFICATEHOLDERS.

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

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

SECTION 8.01   DUTIES OF TRUSTEE.

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

               The  Trustee,  upon  receipt  of all  resolutions,  certificates,
statements,  opinions, reports, documents, orders or other instruments furnished
to the Trustee,  which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they are in
the form required by this Agreement;  provided,  however, that the Trustee shall
not be responsible  for the accuracy or content of any  certificate,  statement,
instrument, report, notice or other document furnished by the Master Servicer or
the Servicers pursuant to Articles III, IV and IX.

               No provision of this Agreement  shall be construed to relieve the
Trustee from liability for its own negligent  action,  its own negligent failure
to act or its own willful misconduct; provided, however, that:

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

                      (ii) The  Trustee  shall  not be  personally  liable  with
        respect to any action  taken,  suffered  or omitted to be taken by it in
        good faith in accordance  with the direction of holders of  Certificates
        which evidence in the aggregate not less than 25% of the Voting Interest
        represented by all Certificates  relating to the time,  method and place
        of conducting any proceeding for any remedy available to the Trustee, or
        exercising  any trust or power  conferred  upon the Trustee,  under this
        Agreement; and

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

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

SECTION 8.02   CERTAIN MATTERS AFFECTING THE TRUSTEE.

               Except as otherwise provided in Section 8.01:

                      (i)  The  Trustee  may  request  and  rely  and  shall  be
        protected  in acting or  refraining  from  acting  upon any  resolution,
        Officers' Certificate, certificate of auditors or any other certificate,
        statement, instrument, opinion, report, notice, request, consent, order,
        appraisal,  bond or other paper or document believed by it to be genuine
        and to have been signed or  presented by the proper party or parties and
        the manner of obtaining consents and evidencing the authorization of the
        execution thereof shall be subject to such reasonable regulations as the
        Trustee may prescribe;

                      (ii) The Trustee may consult with counsel, and any written
        advice of such  counsel  or any  Opinion  of  Counsel  shall be full and
        complete  authorization and protection in respect of any action taken or
        suffered or omitted by it hereunder in good faith and in accordance with
        such advice or Opinion of Counsel;

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

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

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

SECTION 8.03   TRUSTEE NOT REQUIRED TO MAKE INVESTIGATION.

               Prior to the  occurrence  of an Event of  Default  hereunder  and
after the curing of all Events of Default which may have  occurred,  the Trustee
shall not be bound to make any investigation into the facts or matters stated in
any resolution,  certificate,  statement,  instrument,  opinion, report, notice,
request, consent, order, appraisal, bond, Mortgage, Mortgage Note or other paper
or document (provided the same appears regular on its face), unless requested in
writing to do so by holders of Certificates evidencing in the aggregate not less
than 51% of the  Voting  Interest  represented  by all  Certificates;  provided,
however,  that if the  payment  within a  reasonable  time to the Trustee of the
costs, expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee,  not reasonably  assured to the
Trustee  by the  security  afforded  to it by the terms of this  Agreement,  the
Trustee may require reasonable  indemnity against such expense or liability as a
condition to so proceeding.  The reasonable  expense of every such investigation
shall be paid by the Master Servicer or, if paid by the Trustee, shall be repaid
by the Master Servicer upon demand.

SECTION 8.04   TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.

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

SECTION 8.05   TRUSTEE MAY OWN CERTIFICATES.

               The Trustee,  and any agent  thereof,  in its  individual  or any
other capacity,  may become the owner or pledgee of  Certificates  with the same
rights it would  have if it were not  Trustee  or such  agent  and may  transact
banking  and/or trust  business  with the Seller,  the Master  Servicer or their
Affiliates.

SECTION 8.06   THE MASTER SERVICER TO PAY FEES AND EXPENSES.

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

SECTION 8.07   ELIGIBILITY REQUIREMENTS.

               The Trustee  hereunder shall at all times (i) be a corporation or
association  having its principal  office in a state and city  acceptable to the
Seller,  organized and doing business under the laws of such state or the United
States of  America,  authorized  under  such laws to  exercise  corporate  trust
powers, having a combined capital and surplus of at least $50,000,000,  or shall
be a member of a bank holding system, the aggregate combined capital and surplus
of which is at least $50,000,000, provided that its separate capital and surplus
shall at all times be at least the amount specified in Section  310(a)(2) of the
Trust  Indenture Act of 1939,  (ii) be subject to  supervision or examination by
federal  or state  authority  and (iii)  have a credit  rating  or be  otherwise
acceptable to the Rating Agencies such that neither of the Rating Agencies would
reduce  their  respective  then  current  ratings of the  Certificates  (or have
provided  such  security  from  time to  time as is  sufficient  to  avoid  such
reduction) as evidenced in writing by each Rating Agency. If such corporation or
association publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid  supervising or examining  authority,  then
for the  purposes  of this  Section  the  combined  capital  and surplus of such
corporation  or  association  shall be deemed  to be its  combined  capital  and
surplus as set forth in its most recent  report of  condition so  published.  In
case at any time the Trustee shall cease to be eligible in  accordance  with the
provisions of this Section,  the Trustee shall resign  immediately in the manner
and with the effect specified in Section 8.08.

SECTION 8.08   RESIGNATION AND REMOVAL.

               The  Trustee may at any time  resign and be  discharged  from the
trust  hereby  created by giving  written  notice of  resignation  to the Master
Servicer,  such  resignation to be effective upon the appointment of a successor
trustee.  Upon receiving such notice of  resignation,  the Master Servicer shall
promptly appoint a successor trustee by written  instrument,  in duplicate,  one
copy of which instrument shall be delivered to the resigning entity and one copy
to its  successor.  If no successor  trustee shall have been  appointed and have
accepted  appointment  within  30  days  after  the  giving  of such  notice  of
resignation,   the  resigning  Trustee  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor trustee.

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

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

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

SECTION 8.09   SUCCESSOR.

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

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

SECTION 8.10   MERGER OR CONSOLIDATION.

               Any Person into which the Trustee may be merged or  converted  or
with  which  it may be  consolidated,  to  which  it may  sell or  transfer  its
corporate  trust business and assets as a whole or  substantially  as a whole or
any  Person   resulting  from  any  merger,   sale,   transfer,   conversion  or
consolidation to which the Trustee shall be a party, or any Person succeeding to
the business of such entity,  shall be the  successor of the Trustee  hereunder;
provided,  however,  that (i) such Person shall be eligible under the provisions
of Section 8.07, without the execution or filing of any paper or any further act
on the  part of any of the  parties  hereto,  anything  herein  to the  contrary
notwithstanding, and (ii) the Trustee shall deliver an Opinion of Counsel to the
Seller and the Master  Servicer to the effect that such  merger,  consolidation,
sale or transfer  will not  subject 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:

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

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

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

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

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

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

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

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

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

SECTION 8.13   APPOINTMENT OF CUSTODIANS.

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

SECTION 8.14   TAX MATTERS; COMPLIANCE WITH REMIC PROVISIONS.

               (a) Each of the  Trustee and the Master  Servicer  covenants  and
agrees that it shall perform its duties  hereunder in a manner  consistent  with
the REMIC Provisions and shall not knowingly take any action or fail to take any
action that would (i) affect the determination of the Trust Estate's status as 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 Form 8811 and apply for an Employee Identification Number
with a Form SS-4 or any other  permissible  method and respond to  inquiries  by
Certificateholders or their nominees concerning information returns,  reports or
tax returns;  (vi) maintain (or cause to be maintained  by the  Servicers)  such
records  relating  to the  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-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.

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

SECTION 8.15   MONTHLY ADVANCES.

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

SECTION 8.16   TRUSTEE COVENANTS CONCERNING YEAR 2000 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.

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.

as herein  provided  and for other  purposes,  this  Agreement  may be  executed
simultaneously in any number of counterparts,  each of which  counterparts shall
be deemed to be an original,  and such counterparts shall constitute but one and
the same instrument.

SECTION 10.03  LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

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

               Except   as   otherwise    expressly    provided    herein,    no
Certificateholder,  solely by virtue of its status as a Certificateholder, shall
have any right to vote or in any manner  otherwise  control  the  operation  and
management of the Trust Estate,  or the obligations of the parties  hereto,  nor
shall anything herein set forth, or contained in the terms of the  Certificates,
be construed so as to  constitute  the  Certificateholders  from time to time as
partners or members of an association,  nor shall any Certificateholder be under
any  liability  to any third person by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.

               No   Certificateholder,   solely  by  virtue  of  its  status  as
Certificateholder,  shall  have  any  right  by  virtue  or by  availing  of any
provision of this  Agreement  to institute  any suit,  action or  proceeding  in
equity or at law upon or under or with  respect to this  Agreement,  unless such
Holder  previously  shall have given to the Trustee a written  notice of default
and of the continuance  thereof, as hereinbefore  provided,  and unless also the
Holders of  Certificates  evidencing  not less than 25% of the  Voting  Interest
represented by all Certificates shall have made written request upon the Trustee
to  institute  such  action,  suit  or  proceeding  in its own  name as  Trustee
hereunder and shall have offered to the Trustee such reasonable  indemnity as it
may require against the cost, expenses and liabilities to be incurred therein or
thereby, and the Trustee, for 60 days after its receipt of such notice,  request
and offer of  indemnity,  shall have  neglected or refused to institute any such
action,  suit or  proceeding;  it  being  understood  and  intended,  and  being
expressly    covenanted   by   each    Certificateholder    with   every   other
Certificateholder  and the Trustee,  that no one or more Holders of Certificates
shall  have any right in any manner  whatever  by virtue or by  availing  of any
provision of this  Agreement to affect,  disturb or prejudice  the rights of the
Holders  of any  other of such  Certificates,  or to  obtain  or seek to  obtain
priority over or  preference  to any other such Holder,  or to enforce any right
under this  Agreement,  except in the manner herein provided and for the benefit
of all Certificateholders.  For the protection and enforcement of the provisions
of this  Section,  each and every  Certificateholder  and the  Trustee  shall be
entitled to such relief as can be given either at law or in equity.

SECTION 10.04  GOVERNING LAW; JURISDICTION.

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

SECTION 10.06  SEVERABILITY OF PROVISIONS.

               If any one or more of the  covenants,  agreements,  provisions or

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

               THIS CERTIFIES THAT ___________________________ is the registered
owner of the  Percentage  Interest  evidenced  by this  Certificate  in  monthly
distributions  to the Holders of the Class A-1  Certificates  with  respect to a
Trust Estate consisting of a pool of fixed interest rate, conventional,  monthly

loans,  other than the Fixed Retained Yield, if any, with respect  thereto,  and

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 August 27, 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-1 Certificates required to be distributed to
Holders of the Class A-1  Certificates  on such  Distribution  Date,  subject to
adjustment in certain  events as specified in the  Agreement.  Distributions  in
reduction of the Principal  Balance of certain  Classes of Class A  Certificates
may not commence on the first  Distribution Date specified above.  Distributions
of principal  will be  allocated  among the Classes of Class A  Certificates  in
accordance with the provisions of the Agreement.  The  pass-through  rate on the
Class A-1 Certificates  applicable to each  Distribution Date will be 6.500% 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 A-1 Certificates, as described in the Agreement.

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

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

               This  Certificate  is issued on August 27, 1999, and based on its
issue price of 96.42257%,  including accrued  interest,  and a stated redemption
price  at  maturity  equal  to its  initial  principal  balance  (plus 2 days of
interest  at the  pass-through  rate  hereon),  is issued  with  original  issue
discount ("OID") for federal income tax purposes. Assuming that this Certificate
pays  in  accordance  with  projected  cash  flows   reflecting  the  prepayment
assumption of 225% SPA (as defined in the Prospectus Supplement dated August 18,
1999 with respect to the offering of the Class A Certificates  (except the Class
A-PO  Certificates),  Class B-1, Class B-2 and Class B-3  Certificates)  used to
price this  Certificate:  (i) the amount of OID as a  percentage  of the initial
principal  balance of this  Certificate is approximately  3.61154167%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  7.14%;  and (iii) the amount of OID  allocable to the short first
accrual  period  (August 27, 1999 to September  25, 1999) as a percentage of the
initial  principal  balance  of this  Certificate,  calculated  using  the exact
method, is approximately 0.02997584%.

               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.

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

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

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   CERTIFIES   THAT   ____________________________   is   the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
monthly  distributions to the Holders of the Class B-2 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 August 27, 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-2  Distribution  Amount  required to be  distributed  to
Holders of the Class B-2  Certificates  on such  Distribution  Date,  subject to
adjustment,  in certain events, as specified in the Agreement.  The pass-through
rate on the Class B-2 Certificates  applicable to each Distribution Date will be
6.500% per annum.  The amount of interest  which accrues on this  Certificate in
any month  will be  subject  to  reduction  with  respect  to any  Non-Supported
Interest Shortfall and the interest portion of certain Realized Losses allocated
to the Class B-2 Certificates, as described in the Agreement.

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

               No  transfer of a Class B-2  Certificate  will be made unless the
Holder hereof  desiring to make any such  transfer  shall deliver to the Trustee
(i) a representation letter, in the form as described in the Agreement,  stating
either  (a) that the  transferee  is not a Plan and is not acting on behalf of a
Plan or using the assets of a Plan to effect  such  purchase  or (b)  subject to
certain conditions described in the Agreement,  that the source of funds used to
purchase this Certificate is an "insurance  company general account," or (ii) if
such  transferee is a Plan, (a) an opinion of counsel  acceptable to and in form
and substance satisfactory to the Trustee and the Seller with respect to certain
matters and (b) such other  documentation  as the Seller or the Master  Servicer
may require, as described in the Agreement.

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

               This  Certificate  is issued on August 27, 1999, and based on its
issue price of 94.82882%,  including accrued  interest,  and a stated redemption
price  at  maturity  equal  to its  initial  principal  balance  (plus 2 days of
interest  at the  pass-through  rate  hereon),  is issued  with  original  issue
discount ("OID") for federal income tax purposes. Assuming that this Certificate
pays  in  accordance  with  projected  cash  flows   reflecting  the  prepayment
assumption of 225% SPA (as defined in the Prospectus Supplement dated August 18,
1999 with respect to the offering of the Class A Certificates  (except the Class
A-PO  Certificates),  Class B-1, Class B-2 and Class B-3  Certificates)  used to
price this  Certificate:  (i) the amount of OID as a  percentage  of the initial
principal  balance of this  Certificate is approximately  5.20729167%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  7.44%;  and (iii) the amount of OID  allocable to the short first
accrual  period  (August 27, 1999 to September  25, 1999) as a percentage of the
initial  principal  balance  of this  Certificate,  calculated  using  the exact
method, is approximately 0.04281987%.

               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.

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 August 27, 1999 (the
"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master  servicer  (the "Master  Servicer")  and First Union  National  Bank,  as

which  is  set  forth  hereinafter.  To  the  extent  not  defined  herein,  the
capitalized  terms used herein have the  meanings  ascribed to such terms in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

               Pursuant to the terms of the Agreement,  a  distribution  will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing on
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-4  Distribution  Amount  required to be  distributed  to
Holders of the Class B-4  Certificates  on such  Distribution  Date,  subject to
adjustment,  in certain events, as specified in the Agreement.  The pass-through
rate on the Class B-4 Certificates  applicable to each Distribution Date will be
6.500% 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-4 Certificates, as described in the Agreement.

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

               No transfer of a Class B-4  Certificate  will be made unless such
transfer is exempt from the  registration  requirements of the Securities Act of
1933,  as  amended,  and  any  applicable  state  securities  laws or is made in
accordance  with said Act and laws. In the event that such a transfer is desired
to be made by the Holder hereof,  (i) the transferee will be required to execute
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  is issued on August 27, 1999, and based on its
issue price of 76.18819%,  including accrued  interest,  and a stated redemption
price  at  maturity  equal  to its  initial  principal  balance  (plus 2 days of
interest  at the  pass-through  rate  hereon),  is issued  with  original  issue
discount ("OID") for federal income tax purposes. Assuming that this Certificate
pays  in  accordance  with  projected  cash  flows   reflecting  the  prepayment
assumption of 225% SPA (as defined in the Prospectus Supplement dated August 18,
1999 with respect to the offering of the Class A Certificates  (except the Class
A-PO  Certificates),  Class B-1, Class B-2 and Class B-3  Certificates)  used to
price this  Certificate:  (i) the amount of OID as a  percentage  of the initial
principal  balance of this Certificate is approximately  23.84791667%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  11.51%;  and (iii) the amount of OID allocable to the short first
accrual  period  (August 27, 1999 to September  25, 1999) as a percentage of the
initial  principal  balance  of this  Certificate,  calculated  using  the exact
method, is approximately 0.17633727%.

               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.

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-6  Distribution  Amount  required to be  distributed  to
Holders of the Class B-6  Certificates  on such  Distribution  Date,  subject to
adjustment,  in certain events, as specified in the Agreement.  The pass-through
rate on the Class B-6 Certificates  applicable to each Distribution Date will be
6.500% 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-6 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-6  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  is issued on August 27, 1999, and based on its
issue price of 22.71944%,  including accrued  interest,  and a stated redemption
price  at  maturity  equal  to its  initial  principal  balance  (plus 2 days of
interest  at the  pass-through  rate  hereon),  is issued  with  original  issue
discount ("OID") for federal income tax purposes. Assuming that this Certificate
pays  in  accordance  with  projected  cash  flows   reflecting  the  prepayment
assumption of 225% SPA (as defined in the Prospectus Supplement dated August 18,
1999 with respect to the offering of the Class A Certificates  (except the Class
A-PO  Certificates),  Class B-1, Class B-2 and Class B-3  Certificates)  used to
price this  Certificate:  (i) the amount of OID as a  percentage  of the initial
principal  balance of this Certificate is approximately  77.31666667%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  47.19%;  and (iii) the amount of OID allocable to the short first
accrual  period  (August 27, 1999 to September  25, 1999) as a percentage of the
initial  principal  balance  of this  Certificate,  calculated  using  the exact
method, is approximately 0.32722231%.

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

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

                [Form of Reverse of Series 1999-22 Certificates]

                      NORWEST ASSET SECURITIES CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATES
                                 SERIES 1999-22

               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.

                               CUSTODIAL AGREEMENT

               THIS CUSTODIAL  AGREEMENT (as amended and supplemented  from time

(together with any successor in interest or any successor  appointed  hereunder,
the "Custodian").

                                 WITNESSETH THAT

               WHEREAS, the Seller, the Master Servicer,  and the Trustee,  have
entered  into a Pooling  and  Servicing  Agreement  dated as of August 27,  1999
relating to the issuance of Mortgage Pass-Through  Certificates,  Series 1999-22
(as in effect on the date of this Agreement, the "Original Pooling and Servicing
Agreement",  and as amended and supplemented from time to time, the "Pooling and
Servicing Agreement"); and

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

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


                                    ARTICLE I

                                   Definitions

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


                                   ARTICLE II

                          Custody of Mortgage Documents

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

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

               Section 2.03 Review of Custodial Files. The Custodian agrees, for
the benefit of Certificateholders,  to review, in accordance with the provisions
of Section 2.01 of the Pooling and Servicing Agreement,  each Custodial File. If
in performing  the review  required by this Section 2.3 the Custodian  finds any
document or documents  constituting  a part of a Custodial File to be missing or
defective in any material  respect,  the Custodian  shall promptly so notify the
Seller, the Master Servicer and the Trustee.

               Section  2.04  Notification  of Breaches of  Representations  and
Warranties. Upon discovery by the Custodian of a breach of any representation or
warranty  made by the Seller or the Master  Servicer as set forth in the Pooling
and Servicing  Agreement,  the Custodian shall give prompt written notice to the
Seller, the Master Servicer and the Trustee.

               Section 2.05 Custodian to Cooperate;  Release of Custodial Files.
Upon the  payment in full of any  Mortgage  Loan,  or the  receipt by the Master
Servicer  of a  notification  that  payment in full will be escrowed in a manner
customary for such purposes,  the Master Servicer shall  immediately  notify the
Custodian by a certification  (which  certification shall include a statement to
the effect that all amounts  received or to be received in connection  with such
payment which are required to be deposited in the Certificate  Account  pursuant
to Section 3.02 of the Pooling and Servicing  Agreement  have been or will be so
deposited)  of a  Servicing  Officer  and shall  request  delivery  to it of the
Custodial File. The Custodian  agrees,  upon receipt of such  certification  and
request, promptly to release the related Custodial File to the Master Servicer.

               From  time  to  time  as is  appropriate  for  the  servicing  or
foreclosure  of any Mortgage  Loan,  the Master  Servicer  shall  deliver to the
Custodian a certificate of a Servicing  Officer  requesting  that  possession of
all, or any document constituting part of, the Custodial File be released to the
Master  Servicer and  certifying as to the reason for such release and that such
release will not  invalidate any insurance  coverage  provided in respect of the
Mortgage Loan. With such  certificate,  the Master Servicer shall deliver to the
Custodian  a  receipt  signed by a  Servicing  Officer  on behalf of the  Master
Servicer,  and upon receipt of the  foregoing,  the Custodian  shall deliver the
Custodial  File or such  document to the Master  Servicer.  The Master  Servicer
shall  cause each  Custodial  File or any  document  therein so  released  to be
returned  to the  Custodian  when the need  therefor  by the Master  Servicer no
longer  exists,  unless  (i) the  Mortgage  Loan  has  been  liquidated  and the
Liquidation  Proceeds  relating to the Mortgage Loan have been  deposited in the
Certificate  Account  to the  extent  required  by  the  Pooling  and  Servicing
Agreement or (ii) the Custodial  File or such document has been  delivered to an
attorney,  or to a public  trustee or other public  official as required by law,
for purposes of initiating or pursuing legal action or other proceedings for the
foreclosure of the Mortgaged Property either judicially or  non-judicially,  and
the Master  Servicer has delivered to the Custodian a certificate of a Servicing
Officer  certifying  as to the name and  address  of the  Person  to which  such
Custodial  File or such document  were  delivered and the purpose or purposes of
such delivery. In the event of the liquidation of a Mortgage Loan, the Custodian
shall  deliver such receipt with  respect  thereto to the Master  Servicer  upon
deposit of the related  Liquidation  Proceeds in the Certificate  Account to the
extent required by the Pooling and Servicing Agreement.

               Section  2.06  Assumption  Agreements.  In  the  event  that  any
assumption agreement or substitution of liability agreement is entered into with
respect to any Mortgage Loan subject to this  Agreement in  accordance  with the
terms and provisions of the Pooling and Servicing Agreement, the Master Servicer
shall notify the Custodian that such  assumption or  substitution  agreement has
been completed by forwarding to the Custodian the original of such assumption or
substitution agreement,  which copy shall be added to the related Custodial File
and, for all purposes,  shall be considered a part of such Custodial File to the
same extent as all other documents and instruments constituting parts thereof.


                                   ARTICLE III

                            Concerning the Custodian

               Section 3.01  Custodian a Bailee and Agent of the  Trustee.  With
respect to each Mortgage Note,  Mortgage and other documents  constituting  each
Custodian  File  which  are  delivered  to  the  Custodian,   the  Custodian  is
exclusively  the bailee and agent of the Trustee,  holds such  documents for the
benefit of  Certificateholders  and  undertakes  to perform such duties and only
such  duties  as are  specifically  set  forth in this  Agreement.  Except  upon
compliance  with the provisions of Section 2.05 of this  Agreement,  no Mortgage
Note,  Mortgage or other document  constituting a part of a Custodial File shall
be delivered by the Custodian to the Seller or the Master  Servicer or otherwise
released from the possession of the Custodian.

               Section  3.02  Indemnification.   The  Seller  hereby  agrees  to
indemnify  and  hold  the  Custodian  harmless  from  and  against  all  claims,
liabilities,  losses,  actions, suits or proceedings at law or in equity, or any
other expenses,  fees or charges of any character or nature, which the Custodian
may incur or with which the Custodian may be threatened by reasons of its acting
as custodian under this Agreement,  including  indemnification  of the Custodian
against  any and all  expenses,  including  attorney's  fees if counsel  for the
Custodian has been approved by the Seller, and the cost of defending any action,
suit or proceedings or resisting any claim. Notwithstanding the foregoing, it is
specifically  understood and agreed that in the event any such claim, liability,
loss,  action,  suit or proceeding or other expense,  fees, or charge shall have
been caused by reason of any negligent act, negligent failure to act, or willful
misconduct  on the part of the  Custodian,  or which shall  constitute a willful
breach of its duties hereunder, the indemnification provisions of this Agreement
shall not apply.

               Section 3.03 Custodian May Own Certificates. The Custodian in its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Custodian.

               Section  3.04  Master  Servicer  to  Pay  Custodian's   Fees  and
Expenses.  The Master Servicer covenants and agrees to pay to the Custodian from
time to time, and the Custodian  shall be entitled to,  reasonable  compensation
for all services  rendered by it in the exercise and  performance  of any of the
powers and duties  hereunder of the Custodian,  and the Master Servicer will pay
or  reimburse  the  Custodian  upon its  request  for all  reasonable  expenses,
disbursements  and advances incurred or made by the Custodian in accordance with
any of the provisions of this Agreement  (including the reasonable  compensation
and the  expenses  and  disbursements  of its  counsel  and of all  persons  not
regularly in its employ),  except any such expense,  disbursement  or advance as
may arise from its negligence or bad faith.

               Section 3.05 Custodian May Resign;  Trustee May Remove Custodian.
The Custodian may resign from the  obligations and duties hereby imposed upon it
as such obligations and duties relate to its acting as Custodian of the Mortgage
Loans. Upon receiving such notice of resignation,  the Trustee shall either take
custody of the  Custodial  Files  itself and give prompt  notice  thereof to the
Seller,  the Master  Servicer and the Custodian or promptly  appoint a successor
Custodian by written  instrument,  in  duplicate,  one copy of which  instrument
shall be  delivered to the  resigning  Custodian  and one copy to the  successor
Custodian.  If the Trustee shall not have taken  custody of the Custodial  Files
and no  successor  Custodian  shall  have been so  appointed  and have  accepted
resignation,  the  resigning  Custodian  may  petition  any  court of  competent
jurisdiction for the appointment of a successor Custodian.

               The Trustee may remove the  Custodian at any time. In such event,

                                    THE  INTERNAL   REVENUE  CODE  OF  1986,  AS

STATE OF                     )
                             : ss.:
COUNTY OF                    )

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

               1. That he is  [Title of  Officer]  of [Name of  Purchaser]  (the
"Purchaser"),  a  [description  of type of entity] duly  organized  and existing
under the laws of the [State of
       ] [United States], on behalf of which he makes this affidavit.

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

               3. That the Purchaser is not a "disqualified organization" within
the meaning of Section  860E(e)(5),of  the  Internal  Revenue  Code of 1986,  as
amended  (the  "Code"),  or an  ERISA  Prohibited  Holder,  and  will  not  be a
"disqualified  organization"  or an  ERISA  Prohibited  Holder,  as of  [date of
transfer],  and that the  Purchaser is not acquiring  Norwest  Asset  Securities
Corporation  Mortgage  Pass-Through  Certificates,  Series  1999-22,  Class  A-R
Certificate  (the  "Class  A-R  Certificate")  for the  account  of, or as agent
(including a broker, nominee, or other middleman) for, any person or entity from
which  it has  not  received  an  affidavit  substantially  in the  form of this
affidavit.  For these purposes,  a "disqualified  organization" means the United
States, any state or political subdivision thereof, any foreign government,  any
international  organization,  any  agency  or  instrumentality  of  any  of  the
foregoing (other than an instrumentality if all of its activities are subject to
tax  and a  majority  of  its  board  of  directors  is  not  selected  by  such
governmental entity), any cooperative organization furnishing electric energy or
providing  telephone  service  to persons in rural  areas as  described  in Code
Section  1381(a)(2)(C),  or any organization (other than a farmers'  cooperative
described  in Code  Section  521) that is exempt  from  taxation  under the Code
unless such  organization  is subject to the tax on  unrelated  business  income
imposed by Code Section 511. For these purposes,  an "ERISA  Prohibited  Holder"
means an employee benefit plan or other retirement  arrangement subject to Title
I of the Employee  Retirement Income Security Act of 1974, as amended ("ERISA"),
or Code  Section 4975 or a  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.  The term "U.S.  Person" means a
citizen or resident of the United States, a corporation or partnership  (unless,
in the case of a  partnership,  Treasury  regulations  are adopted  that provide
otherwise)  created or organized in or under the laws of the United States,  any
state  thereof or the  District of Columbia,  including  an entity  treated as a
corporation  or  partnership  for federal  income tax purposes,  an estate whose
income is subject to United States  federal income tax regardless of its source,
or a trust if a court  within  the  United  States is able to  exercise  primary
supervision  over the  administration  of such trust,  and one or more such U.S.
Persons have the  authority to control all  substantial  decisions of such trust
(or, to the extent provided in applicable Treasury  regulations,  certain trusts
in  existence  on August 20,  1996 which are  eligible to elect to be treated as
U.S. Persons).

               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.

Corporation  Mortgage  Pass-Through  Certificates,  Series  1999-22.  Section 2.
Representations and Warranties of the Purchaser. In connection with the proposed

               (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

               (b) The  Purchaser is acquiring  the Class  [A-PO][B-4][B-5][B-6]

               [(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 June 22, 1999, 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

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.

        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 2.02  Purchaser's Election to Delay
                             Foreclosure Proceedings.

               (a) The Purchaser shall be deemed to direct the Company to direct
(to the extent that the Company as Master  Servicer is granted such authority in
the related Servicing Agreement) the related Servicer that in the event that the
Company does not receive written notice of the Purchaser's  election pursuant to
subsection (b) below within 24 hours (exclusive of any intervening  non-Business
Days) of  transmission  of the notice provided by the Company under Section 2.01
(a) (ii)  subject to  extension  as set forth in Section  2.02(b),  the  related
Servicer may proceed with the  Commencement  of  Foreclosure  in respect of such
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 2.03  Purchaser's Election to Commence Foreclosure
                             Proceedings.

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

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

                       COLLATERAL FUND; SECURITY INTEREST

               Section 3.01  Collateral Fund.

               Upon receipt from the Purchaser of the initial amount required to
be deposited in the  Collateral  Fund  pursuant to Article II, the Company shall
establish and maintain with Bankers Trust Company as a segregated account on its
books and records an account (the  "Collateral  Fund"),  entitled  "Norwest Bank
Minnesota,  National  Association,  as  Master  Servicer,  for  the  benefit  of
registered holders of Norwest Asset Securities Corporation Mortgage Pass-Through
Certificates, Series 1999-22. 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 3.02  Collateral Fund Permitted Investments.

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

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

               Section 3.03  Grant of Security Interest.

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

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

               Section 3.04  Collateral Shortfalls.

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