ITEM 5.     OTHER EVENTS

On  February  25,  1999,  Norwest  Asset  Securities  Corporation,   a  Delaware
corporation (the "Registrant"),  sold Mortgage Pass-Through Certificates, Series
1999-6,  Class A-1, Class A-2, Class A-3, Class A-4, Class A-R, Class B-1, Class
B-2 and Class B-3 (the  "Offered  Certificates"),  having an aggregate  original
principal balance of $174,203,100. The Offered Certificates were issued pursuant
to a Pooling and Servicing  Agreement,  dated as of February 25, 1999, among the
Registrant,  Norwest Bank Minnesota,  National  Association,  as master servicer
(the "Master  Servicer" or "Norwest  Bank"),  United States Trust Company of New
York, as trustee,  and First Union  National Bank, as trust  administrator  (the
"Agreement"),  a  copy  of  which  is  filed  as  an  exhibit  hereto.  Mortgage
Pass-Through  Certificates,  Series 1999-6,  Class A-PO Certificates,  having an
aggregate  initial principal balance of $212,417.21 and Class B-4, Class B-5 and
Class B-6  Certificates,  having  an  aggregate  initial  principal  balance  of
$876,569.47  (the "Private Class B  Certificates"  and,  together with the Class
A-PO Certificates and the Offered Certificates,  the "Certificates"),  were also
issued pursuant to the Agreement.

As of the date of  initial  issuance,  the  Offered  Certificates  evidenced  an
approximate  99.38%  undivided  interest in a trust fund (the  "Trust  Estate"),
consisting principally of a pool of fixed interest rate,  conventional,  monthly
pay,  fully-amortizing,  one-to  four-family  residential  first mortgage loans,
other than the Fixed  Retained  Yield (as defined in the  Agreement),  which may
include  loans  secured by shares issued by  cooperative  housing  corporations,
originated in connection  with the relocation of employees by various  corporate
employers that participated in the relocation program of Norwest Mortgage,  Inc.
and of employees of various non-participant  employees.  The remaining undivided
interests in the Trust Estate are  evidenced by the Class A-PO and Private Class
B  Certificates.   Distributions   on  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-2,  Class A-3,  Class A-4,
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.

                  instrument or of a writing appointing any such agent shall
                  be sufficient for any purpose of this Agreement and
                  conclusive in favor of the Trustee and the Trust

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

            (d)   The ownership of Certificates (whether or not such
                  Certificates shall be overdue and notwithstanding any
                  notation of ownership or other writing thereon made by
                  anyone other than the Trustee, the Trust Administrator and
                  the Authenticating Agent) shall be proved by the
                  Certificate Register, and neither the Trustee, the Trust
                  Administrator, the Seller nor the Master Servicer shall be
                  affected by any notice to the contrary.

            (e)   Any request, demand, authorization, direction, notice,
                  consent, waiver or other action of the Holder of any
                  Certificate shall bind every future Holder of the same
                  Certificate and the Holder of every Certificate issued upon
                  the registration of transfer thereof or in exchange
                  therefor or in lieu thereof in respect of anything done,
                  omitted or suffered to be done by the Trustee, the Trust
                  Administrator, the Seller or the Master Servicer in
                  reliance thereon, whether or not notation of such action is

                                   ARTICLE II


                          CONVEYANCE OF MORTGAGE LOANS;
                      ORIGINAL ISSUANCE OF THE CERTIFICATES

     Section 2.01   CONVEYANCE OF MORTGAGE LOANS.

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

In  connection  with such  assignment,  the Seller  shall,  with respect to each
Mortgage Loan, deliver, or cause to be delivered, to the Trust Administrator, 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 Trust Administrator 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 Trust Administrator  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 Trust  Administrator  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 Trust  Administrator  within  one (1) year  following  the
Closing Date any original  Mortgage or assignment of a Mortgage not delivered to
the Trust Administrator 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 Trust  Administrator  the  assignment of the Mortgage Loan from
the  Seller to the  Trust  Administrator  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 Trust Administrator and the Trust Administrator shall within
five Business Days (or such other reasonable period of time mutually agreed upon
by the  Master  Servicer  and the Trust  Administrator)  of its  receipt of such
notice deliver each previously unrecorded assignment to the related Servicer for
recordation.

     Section 2.02   ACCEPTANCE BY TRUST ADMINISTRATOR.

The Trust Administrator,  on behalf of 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  Trust  Administrator   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 Trust Administrator 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
Trust Administrator 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 Trust  Administrator  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 Trust  Administrator'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 Trust
Administrator 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 Trust Administrator 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  Trust   Administrator  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 Trust  Administrator  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,  the Trust
Administrator  on  behalf  of the  Trustee  and the  Trustee  on  behalf  of the
Certificateholders.  The failure of the Trust  Administrator  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 Trust Administrator 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 Trust  Administrator  appoints a
Custodian to hold the Mortgage Notes,  the Mortgages,  the assignments and other
documents related to the Mortgage Loans received by the Trust Administrator,  as
agent for 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 2.02   REPRESENTATIONS  AND  WARRANTIES OF THE MASTER  SERVICER AND
                    THE SELLER.

The Master Servicer hereby  represents and warrants to the Trustee and the Trust
Administrator  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,   the  Trust  Administrator  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 Trust Administrator or the Custodian.

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

      herein, the Seller was the sole owner and holder of the Mortgage Loan free

      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

      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)

      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 Trust  Administrator,  on
      behalf of 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

      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

      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)

      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

      360 months;

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

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

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

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

      been delivered to the Trust Administrator 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

      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 Trust  Administrator  and shall  inure to the  benefit of the
Trust Administrator,  on behalf of the Trustee,  notwithstanding any restrictive
or qualified endorsement or assignment.

Upon  discovery  by  either  the  Seller,   the  Master   Servicer,   the  Trust
Administrator,  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,  the Trust  Administrator  on behalf of the Trustee,  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 Trust Administrator  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

                                   ARTICLE III

                  ADMINISTRATION OF THE TRUST ESTATE: SERVICING
                              OF THE MORTGAGE LOANS

     Section 3.01   CERTIFICATE ACCOUNT.

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.

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

            (i) Periodic Advances pursuant to Section 3.03(a) made by the Master
      Servicer  or the  Trust  Administrator,  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.

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.

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.

The  Master  Servicer  may,  from  time  to  time,  make  withdrawals  from  the
Certificate Account for the following purposes (limited, in the case of Servicer
reimbursements, to cases where funds in the respective Custodial P&I Account are
not  sufficient  therefor):   to  reimburse  the  Master  Servicer,   the  Trust
Administrator or any Servicer for Periodic  Advances made by the Master Servicer

      Administrator for any Periodic  Advances  determined in good faith to have

      reimbursable only from amounts  constituting  Fixed Retained Yield and not
      from the assets of the Trust Estate;

            (ii)  to  reimburse  the  Master   Servicer  or  any  Servicer  from
      Liquidation  Proceeds for Liquidation Expenses and for amounts expended by
      the Master  Servicer or any Servicer  pursuant  hereto or to any Servicing
      Agreement,  respectively, in good faith in connection with the restoration
      of damaged property or for foreclosure expenses;

      repurchase  or  purchase   price  or  Scheduled   Principal   Balance  was
      determined;

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

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

            (viii)  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;

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

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

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

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 TRUST ADMINISTRATOR.

In the event an Other Servicer fails to make any required  Periodic  Advances of
principal  and  interest on a Mortgage  Loan as  required  by the related  Other
Servicing Agreement prior to the Distribution Date occurring in the month during
which such  Periodic  Advance is due, the Master  Servicer  shall make  Periodic
Advances to the extent provided  hereby.  In the event Norwest Mortgage fails to
make any required Periodic Advances of principal and interest on a Mortgage Loan
as required by the Norwest  Servicing  Agreement prior to the Distribution  Date
occurring  in the month  during  which such  Periodic  Advance is due, the Trust
Administrator  shall, to the extent required by Section 8.15, make such Periodic
Advance to the extent provided hereby, provided that the Trust Administrator has
previously  received the  certificate  of the Master  Servicer  described in the
following sentence. The Master Servicer shall certify to the Trust Administrator
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 Trust  Administrator  or Master  Servicer  is  required  to
advance  hereunder and (iv) whether the Master  Servicer has determined  that it
reasonably  believes that such  Periodic  Advance is a  Nonrecoverable  Advance.
Amounts  advanced  by the  Trust  Administrator  or  Master  Servicer  shall  be
deposited  in  the  Certificate  Account  on  the  related   Distribution  Date.
Notwithstanding  the  foregoing,  neither  the  Master  Servicer  nor the  Trust
Administrator  will be obligated to make a Periodic  Advance that it  reasonably
believes  to  be  a  Nonrecoverable   Advance.   The  Trust   Administrator  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.

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 Trust  Administrator that such
failure  has   occurred.   Upon  receipt  of  such   certification,   the  Trust
Administrator  shall  advance such funds and take such steps as are necessary to
pay such taxes or insurance premiums.

The Master  Servicer  and the Trust  Administrator  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  Trust  Administrator  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 Trust
Administrator,  withdraw  from the  Certificate  Account  and remit to the Trust
Administrator  any  amounts  to which the Trust  Administrator  is  entitled  as
reimbursement pursuant to Section 3.02 (a)(i), (ii) and (v).

Except as provided in Section  3.03(a) and (b),  neither the Master Servicer nor
the Trust Administrator 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   TRUST ADMINISTRATOR 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 Trust  Administrator  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  Trust
Administrator.  The Trust Administrator  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 Trust Administrator and the Trust Administrator  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 Trust  Administrator  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 Trust Administrator
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 Trust Administrator to the Master Servicer or such Servicer,  as
appropriate.

Upon written  certification of the Master Servicer or the Servicer of a Mortgage
Loan, the Trust  Administrator  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 Trust  Administrator  and a  statement  as to the  reason  such
documents or pleadings are required and that the execution and delivery  thereof
by the Trust  Administrator  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  AND  TRUST  ADMINISTRATOR;  ANNUAL
                    COMPLIANCE STATEMENTS.

Not later than 15 days after each  Distribution  Date, the Master Servicer shall
deliver to the Trustee and the Trust Administrator 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  Trust  Administrator  to  any
Certificateholder upon written request, provided such statement is delivered, or
caused to be delivered, by the Master Servicer to the Trust Administrator.

The Master Servicer shall deliver to the Trustee and the Trust  Administrator 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 Trust  Administrator to any
Certificateholder  upon written request  provided such certificate is delivered,
or caused to be delivered, by the Master Servicer to the Trust Administrator.

     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 Trust Administrator  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 Trust Administrator shall have no further responsibility with regard to such
Owner  Mortgage  Loan File or  Servicer  Mortgage  Loan File.  Neither the Trust
Administrator,  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.

Subject to the prior written consent of the Trustee and the Trust  Administrator
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 and the Trust  Administrator
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.

The  Trustee  and the Trust  Administrator  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 and
the Trust  Administrator  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,  either the Trustee or the Trust Administrator 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.

(xii) Notwithstanding  anything to the contrary in this Section 3.07, the Master
Servicer  from time to time may,  without the consent of any  Certificateholder,
the Trustee, or the Trust Administrator, 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).

   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 Trust Administrator'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 Trust  Administrator  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 Trust  Administrator  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  and  the  Trust
Administrator  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 Trust  Administrator  on behalf of 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 Trust
Administrator  the  certification   required  by  Section  3.04  and  the  Trust
Administrator  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 Trust Administrator  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 Trust Administrator shall have no further  responsibility with regard to
such Owner Mortgage Loan File or Servicer Mortgage Loan File.  Neither the Trust
Administrator,  the Master  Servicer nor any  Servicer,  acting on behalf of the
Trust  Administrator,  shall  provide  financing  from the  Trust  Estate to any
purchaser of a Mortgage Loan.

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

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

     Section 3.09   TERMINATION AND SUBSTITUTION OF SERVICING AGREEMENTS.

Upon the occurrence of any event for which a Servicer may be terminated pursuant
to its Servicing  Agreement,  the Master Servicer shall promptly  deliver to the
Seller and the Trustee an  Officer's  Certificate  certifying  that an event has
occurred which may justify termination of such Servicing  Agreement,  describing
the circumstances  surrounding such event and recommending what action should be
taken by the  Trustee  with  respect to such  Servicer.  If the Master  Servicer
recommends that such Servicing  Agreement be terminated,  the Master  Servicer's
certification must state that the breach is material and not merely technical in
nature.  Upon  written  direction  of  the  Master  Servicer,  based  upon  such
certification,  the Trustee shall promptly  terminate such Servicing  Agreement.
Notwithstanding  the foregoing,  in the event that (i) Norwest Mortgage fails to
make any advance, as a consequence of which the Trust Administrator is obligated
to make an advance  pursuant  to Section  3.03 and (ii) the Trust  Administrator
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  Trust  Administrator  shall  recommend  to the  Trustee  the
termination of the Norwest Servicing Agreement without the recommendation of the
Master  Servicer and upon such  recommendation,  the Trustee shall terminate the
Norwest Servicing Agreement. The Master Servicer shall indemnify the Trustee and
the Trust  Administrator  and hold each  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 or
the  Trust  Administrator  in  connection  with  termination  of such  Servicing
Agreement at the  direction  of the Master  Servicer.  In  addition,  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  attorney's  fees) arising out of, or assessed against the Trustee in
connection with the termination of the Norwest  Servicing  Agreement as provided
in the second  preceding  sentence.  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 Trust  Administrator,  the
Master  Servicer and each Rating Agency under which the Master  Servicer or such
substitute  servicer,  as the case may be, shall  assume,  satisfy,  perform and
carry out all liabilities,  duties, responsibilities and obligations that are to
be, or otherwise were to have been, satisfied, performed and carried out by such
Servicer  under  such  terminated  Servicing  Agreement.  Until such time as the
Trustee  enters  into a  substitute  servicing  agreement  with  respect  to the
Mortgage Loans previously  serviced by such Servicer,  the Master Servicer shall
assume,  satisfy,  perform and carry out all obligations which otherwise were to
have been  satisfied,  performed  and  carried  out by such  Servicer  under its
terminated Servicing  Agreement.  However, in no event shall the Master Servicer
be deemed to have assumed the  obligations of a Servicer to advance  payments of
principal  and  interest on a delinquent  Mortgage  Loan in excess of the Master
Servicer's  independent  Periodic Advance  obligation under Section 3.03 of this
Agreement.  As compensation for the Master Servicer of any servicing obligations
fulfilled  or assumed  by the Master  Servicer,  the  Master  Servicer  shall be
entitled  to any  servicing  compensation  to which a  Servicer  would have been
entitled if the Servicing Agreement with such Servicer had not been terminated.

     Section 3.10   APPLICATION OF NET LIQUIDATION PROCEEDS.

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

     Section 3.11   ACT REPORTS.

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

by the  amount,  if any,  that  would have been  distributable  to the Class B-3
Certificates hereunder used to pay the Class A-PO Deferred Amount as provided in

fourteenth,  to the Class  B-4  Certificates  in an  amount  up to the  Interest

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.

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-4  Certificates,  up to the  Priority  Amount  for such
Distribution Date;

second,  sequentially,  to the Class  A-R,  Class  A-1,  Class A-2 and Class A-3
Certificates,  in that order, until the Principal Balance of each such Class has
been reduced to zero; and

third, to the Class A-4 Certificates,  without regard to the Priority Amount for
such Distribution  Date, until the Principal Balance thereof has been reduced to
zero;

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).

(xiii) 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

                           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

                           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

                           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

                           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.

              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.

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

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

     Section 4.02   ALLOCATION OF REALIZED LOSSES.

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.

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.

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.

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.

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.

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 Trust  Administrator  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  Trust
Administrator to execute and deliver to the Trust Administrator an instrument in
which such Paying  Agent  agrees with the Trust  Administrator  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 Trust  Administrator  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 Trust Administrator, forthwith pay to the Trust
      Administrator 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

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 Trust Administrator,  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.

In the  case  of  information  furnished  with  respect  to a Class  of  Class A

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

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

Administrator  and the Paying  Agent shall be protected in relying upon the same

In addition to the reports  required  pursuant to this Section 4.04,  the Master
Servicer  shall make  available  upon  request to each Holder and each  proposed

The Master  Servicer  shall, in each year beginning after the Cut-Off Date, make

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

     Section 4.06   CALCULATION OF AMOUNTS;  BINDING  EFFECT OF  INTERPRETATIONS
                    AND ACTIONS OF MASTER SERVICER.

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

                                THE CERTIFICATES

     Section 5.01   THE CERTIFICATES.

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 and Class
A-R  Certificates,  integral  multiples of $1,000 in excess thereof (except,  if
necessary,  for one  Certificate  of each Class (other than Class A-PO and Class
A-R  Certificates)  that evidences one Single  Certificate  plus such additional
principal  portion as is required in order for all Certificates of such Class to
equal the  aggregate  Original  Principal  Balance of such Class),  and shall be
substantially  in the respective forms set forth as Exhibits A-1, A-2, A-3, A-4,
A-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 Trust  Administrator  to or upon the order of the Seller upon receipt by the
Trust Administrator 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 Trust  Administrator  by any  Responsible
Officer  thereof.  Certificates  bearing the manual or facsimile  signatures  of
individuals who were at any time the proper officers of the Trust  Administrator
shall bind the Trust Administrator  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 Trust Administrator,  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."

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 Trust Administrator 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
Trust Administrator at the Corporate Trust Office.

     Section 5.02   REGISTRATION OF CERTIFICATES.

The Trust Administrator 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 Trust  Administrator  shall provide for the registration of Certificates and
of  transfers  and  exchanges  of  Certificates  as herein  provided.  The Trust
Administrator  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 Trust  Administrator  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 Trust Administrator 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 Trust  Administrator)
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 Trust Administrator 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 Trust Administrator or the Authenticating  Agent in
accordance with their standard procedures.

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
Trust  Administrator  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 Trust Administrator
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 Trust  Administrator,  the Trustee,  the
Seller or the Master Servicer,  and (ii) the Trust  Administrator  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 Trust  Administrator the facts  surrounding such transfer,  which
investment  letter  shall  not be an  expense  of the Trust  Administrator,  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 Trust  Administrator,  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
Trust  Administrator  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.

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 Trust  Administrator 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 Trust  Administrator,  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 Trust Administrator 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 Trust  Administrator,  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 Trust  Administrator,  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 Trust  Administrator,  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.

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 Trust  Administrator 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 Trust  Administrator  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 Trust Administrator 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 Trust  Administrator  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
Trust Administrator 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 Trust  Administrator  or
the Authenticating Agent, or the Trust Administrator 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 Trust  Administrator  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  Trust
Administrator  or the  Authenticating  Agent  that  such  Certificate  has  been
acquired by a bona fide  purchaser,  the Trust  Administrator  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 Trust Administrator 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 Trust  Administrator  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  Trust  Administrator,   the
Certificate  Registrar  and any agent of the Seller,  the Master  Servicer,  the
Trustee,  the Trust  Administrator  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 Trust Administrator,  the Certificate  Registrar nor
any  agent  of  the  Seller,  the  Master  Servicer,   the  Trustee,  the  Trust
Administrator  or the  Certificate  Registrar shall be affected by notice to the
contrary.

     Section 5.05   ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND ADDRESSES.

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

If five or more  Certificateholders  (hereinafter  referred to as  "applicants")
apply in writing to the Trust  Administrator,  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  Trust  Administrator  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
Trust Administrator. 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 Trust  Administrator is
not the Certificate  Registrar,  the Trust  Administrator 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.

Every Certificateholder, by receiving and holding a Certificate, agrees with the
Seller, the Master Servicer, the Certificate Registrar,  the Trust Administrator
and the Trustee that neither the Seller,  the Master  Servicer,  the Certificate
Registrar,  the Trust Administrator 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 Trust Administrator 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 Trust Administrator 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 Trust  Administrator  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 Trust Administrator 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 Trust  Administrator  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 Trust  Administrator  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 Trust  Administrator  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 Trust  Administrator  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,  the Trustee nor the Trust Administrator 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 Trust
Administrator 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 and
the Trust  Administrator.  No such resignation  shall become effective until the
Trustee,  the Trust Administrator 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 the Trust  Administrator,  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 or the Trust  Administrator  (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 and the Trust
Administrator,  in the  exercise of its  reasonable  judgment,  and executes and
delivers to the Trustee and the Trust  Administrator  an agreement,  in form and
substance  reasonably  satisfactory to the Trustee and the Trust  Administrator,
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, Trust Administrator 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,  TRUST  ADMINISTRATOR AND SELLER
                    BY MASTER SERVICER.

The Master  Servicer  shall  indemnify and hold harmless the Trustee,  the Trust
Administrator 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,  the Trust  Administrator  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.

                                   ARTICLE VII


                                     DEFAULT

     Section 7.01   EVENTS OF DEFAULT.

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

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

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

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

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

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

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

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

then, and in each and every such case,  subject to applicable law, so long as an
Event of Default shall not have been remedied, either the Trustee or the holders
of  Certificates  evidencing  in the  aggregate  not  less  than  66 2/3% of the
aggregate Voting Interest represented by all Certificates,  by notice in writing
to the Master Servicer and the Trust  Administrator (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 Trust  Administrator  on behalf of the Trustee pursuant to and under this
Section, subject to the provisions of Section 7.05; and, without limitation, the
Trust  Administrator on behalf of 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 Trust  Administrator  and 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 Trust Administrator
on behalf of 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 or the Trust Administrator shall have knowledge of
any failure of the Master  Servicer  specified in Section  7.01(i) or (ii) which
would  become an Event of Default upon the Master  Servicer's  failure to remedy
the same after notice, the Trustee or the Trust  Administrator may, but need not
if the Trustee or the Trust  Administrator,  as the case may be, deems it not in
the  Certificateholders'  best  interest,  give  notice  thereof  to the  Master
Servicer. For all purposes of this Agreement, in the absence of actual knowledge
by a  corporate  trust  officer of the Trustee or the Trust  Administrator,  the
Trustee or the Trust  Administrator,  as the case may be, 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   TRUST ADMINISTRATOR TO ACT; APPOINTMENT OF SUCCESSOR.

When the Master Servicer receives notice of termination pursuant to Section 7.01
or the Trustee or the Trust Administrator receives the resignation of the Master
Servicer  evidenced by an Opinion of Counsel pursuant to Section 6.04, the Trust
Administrator on behalf of 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 Trust
Administrator  is succeeding to the Master Servicer as the Master  Servicer,  as
compensation  therefor,  the Trust  Administrator  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 Trust  Administrator
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 Trust Administrator 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 Trust Administrator 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 Trust Administrator is required to solicit bids as provided above,
the Trust Administrator 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 Trust  Administrator  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 Trust  Administrator  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
Trust Administrator 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 Trust  Administrator  to the Master Servicer at the time of
such sale, transfer and assignment to the Master Servicer's successor. The Trust
Administrator  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 Trust  Administrator  and any  successor
servicer  in  effecting  the  termination  of the  Master  Servicer's  servicing
responsibilities  and rights  hereunder  and shall  promptly  provide  the Trust
Administrator 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 Trust
Administrator  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 Trust  Administrator  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 Trust
Administrator)  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 Trust  Administrator  shall give
prompt  written  notice  thereof  to   Certificateholders  at  their  respective
addresses appearing in the Certificate  Register.  The Trust Administrator shall
also,  within 45 days after the  occurrence of any Event of Default known to the
Trust Administrator,  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 AND THE TRUST ADMINISTRATOR

     Section 8.01   DUTIES OF TRUSTEE AND THE TRUST ADMINISTRATOR.

The Trustee and the Trust Administrator,  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 and the Trust Administrator,  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  and the Trust  Administrator,  upon  receipt  of all  resolutions,
certificates,   statements,   opinions,  reports,  documents,  orders  or  other
instruments  furnished  to the  Trustee and the Trust  Administrator,  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  and  the  Trust
Administrator  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 and the
Trust  Administrator  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  and the  Trust  Administrator  shall be
      determined solely by the express provisions of this Agreement, the Trustee
      and the Trust Administrator 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 the Trust  Administrator  and, in the
      absence  of  bad  faith  on  the  part  of  the   Trustee  and  the  Trust
      Administrator,  the Trustee and the Trust  Administrator  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  the  Trust   Administrator,   and   conforming  to  the
      requirements of this Agreement;

            (ii) The Trustee and the Trust Administrator 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 and the Trust Administrator,  or exercising any trust or power
      conferred  upon  the  Trustee  and the  Trust  Administrator,  under  this
      Agreement; and

            (iii) The  Trustee and the Trust  Administrator  shall not be liable
      for any error of  judgment  made in good faith by any of their  respective
      Responsible  Officers,  unless it shall be proved  that the Trustee or the
      Trust  Administrator 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 or
the Trust  Administrator  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  AND  THE  TRUST
ADMINISTRATOR.

Except as otherwise provided in Section 8.01:

            (i) Each of the Trustee and the Trust  Administrator 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 or Trust  Administrator,  as  applicable,  may
      prescribe;

            (ii) Each of the  Trustee  and the Trust  Administrator  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 Opinion of Counsel;

            (iii)  Neither of the Trustee nor the Trust  Administrator  shall 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 Trust  Administrator  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
      Trust  Administrator may be required to act as Master Servicer pursuant to
      Section  7.05 and  thereupon  only for the acts or  omissions of the Trust
      Administrator as successor Master Servicer; and

            (v) Each of the Trustee and the Trust  Administrator 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   NEITHER  TRUSTEE  NOR TRUST  ADMINISTRATOR  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, neither the Trustee nor the Trust
Administrator shall 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 or the Trust  Administrator  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 or the Trust Administrator, not reasonably assured to the
Trustee or the Trust  Administrator by the security  afforded to it by the terms
of this Agreement, the Trustee or the Trust Administrator 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 or the Trust Administrator,  shall be repaid
by the Master Servicer upon demand.

     Section 8.04   NEITHER   TRUSTEE   NOR  TRUST   ADMINISTRATOR   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 neither the Trustee nor the Trust  Administrator
assumes  responsibility  as to the correctness of the same.  Neither the Trustee
nor the Trust  Administrator makes any representation for the correctness of the
same. Neither the Trustee nor the Trust  Administrator  makes any representation
as to the validity or sufficiency of this Agreement or of the Certificates or of
any Mortgage  Loan or related  document.  Subject to Section  2.04,  neither the
Trustee  nor  the  Trust  Administrator  shall  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 AND TRUST ADMINISTRATOR MAY OWN CERTIFICATES.

Each of the  Trustee,  the Trust  Administrator  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,  Trust
Administrator  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 each of the Trustee and the
Trust  Administrator  from time to time,  and each of the  Trustee and the Trust
Administrator 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 or the Trust  Administrator,  as the
case may be, and the Master  Servicer  will pay or reimburse  the Trustee or the
Trust  Administrator,  as the case may be, 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.

Each of the Trustee and the Trust Administrator 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  or the Trust  Administrator  shall
cease to be eligible in accordance  with the  provisions  of this Section,  such
entity shall resign  immediately in the manner and with the effect  specified in
Section 8.08.

     Section 8.08   RESIGNATION AND REMOVAL.

Either of the Trustee or the Trust  Administrator  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 or trust  administrator.  Upon  receiving  such  notice of
resignation,  the Master Servicer shall promptly appoint a successor  trustee or
trust  administrator  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  or trust  administrator  shall  have been
appointed and have accepted  appointment within 30 days after the giving of such
notice of resignation, the resigning Trustee or Trust Administrator, as the case
may be, may petition any court of competent  jurisdiction for the appointment of
a successor trustee or trust administrator.

If at any time the Trustee or the Trust Administrator 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 or the Trust  Administrator  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 the Trust  Administrator  or of the property or affairs of the
Trustee or the Trust Administrator 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/or the Trust  Administrator,  as the case
may be, and appoint a successor trustee and/or successor trust  administrator by
written  instrument,  in  duplicate,  one  copy of  which  instrument  shall  be
delivered to the Trustee or Trust  Administrator  so removed and one copy to the
successor trustee or successor trust administrator, as the case may be.

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/or
the Trust  Administrator  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  or the Trust  Administrator  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 or successor trust administrator  appointed as provided in
Section 8.08 shall execute,  acknowledge  and deliver to the Master Servicer and
to its  predecessor  trustee  or trust  administrator,  as the  case may be,  an
instrument accepting such appointment  hereunder,  and thereupon the resignation
or  removal  of the  predecessor  trustee or trust  administrator  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 or
trust  administrator,  as the case may be, herein.  The  predecessor  trustee or
trust administrator 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 or successor  trust
administrator,  as the  case  may  be,  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 or trust
administrator  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 or successor
trust  administrator,  as the  case  may be,  the  successor  trustee  or  trust
administrator  shall cause such notice to be mailed at the expense of the Master
Servicer.

     Section 8.10   MERGER OR CONSOLIDATION.

Any Person  into  which  either the  Trustee or the Trust  Administrator  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 or the Trust  Administrator  shall be a
party,  or any Person  succeeding  to the business of such entity,  shall be the
successor of the Trustee or Trust Administrator,  as the case may be, 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 or the Trust  Administrator,  as the case
may be,  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 or the Trust Administrator, as the case may be.

     Section 8.11   AUTHENTICATING AGENT.

The Trust  Administrator  may appoint an  Authenticating  Agent,  which shall be
authorized  to act  on  behalf  of the  Trust  Administrator  in  authenticating
Certificates. Wherever reference is made in this Agreement to the authentication
of  Certificates  by  the  Trust  Administrator  or  the  Trust  Administrator's
countersignature,  such reference shall be deemed to include  authentication  on
behalf of the Trust Administrator by the Authenticating  Agent and a certificate
of  authentication  executed  on  behalf  of  the  Trust  Administrator  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 Trust Administrator 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 Trust  Administrator,
the Seller  and the Master  Servicer.  The Trust  Administrator  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 Trust Administrator  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 Trust  Administrator.  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 Trust  Administrator  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 Trust
Administrator,  by entering into a Custodial Agreement.  Subject to this Article
VIII, the Trust Administrator  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.

Each of the Trustee,  the Trust  Administrator 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  Trust
Administrator,  the  Trust  Administrator,  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 Trust  Administrator  and  calculated on a monthly basis by
using the issue  prices of the  Certificates;  (iv) make  available  information
necessary  for the  application  of any tax imposed on  transferors  of residual
interests to "disqualified  organizations" (as defined in the REMIC Provisions);
(v) file Forms SS-4 and 8811 and respond to inquiries by  Certificateholders  or
their nominees  concerning  information  returns,  reports or tax returns;  (vi)
maintain (or cause to be maintained by the Servicers)  such records  relating to
the  REMIC,  including  but not  limited  to the  income,  expenses,  individual
Mortgage Loans  (including REO Mortgage  Loans,  other assets and liabilities of
the REMIC,  and the fair market value and adjusted  basis of the REMIC  property
determined at such intervals as may be required by the Code, as may be necessary
to  prepare  the  foregoing  returns  or  information  reports;  (vii)  exercise
reasonable care not to allow the creation of any "interests" in the REMIC within
the meaning of Code Section  860D(a)(2) other than the interests  represented by
the Class  A-1,  Class  A-2,  Class  A-3,  Class  A-4,  Class A-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 a 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  and comply with  written  directions  from the Master  Servicer or the
Trust Administrator.

In order to enable the Master Servicer,  the Trust Administrator 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,  the Trust  Administrator  or the Trustee,  as the case may be,
promptly upon request therefor, any such additional information or data that the
Master Servicer, the Trust Administrator 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,
the Trust  Administrator  or the  Trustee,  as the case may be, for any  losses,
liabilities,  damages,  claims or  expenses  of the Master  Servicer,  the Trust
Administrator or the Trustee arising from any errors or  miscalculations  by the
Master Servicer, the Trust Administrator 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,  the  Trust
Administrator or the Trustee,  as the case may be, on a timely basis. The Master
Servicer hereby indemnifies the Seller, the Trust  Administrator and the Trustee
for any losses,  liabilities,  damages,  claims or  expenses of the Seller,  the
Trust  Administrator 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 Trust Administrator prepares any of the federal, state and local tax returns
of the REMIC as described above, the Trust Administrator  hereby indemnifies the
Seller,  the  Master  Servicer  and the  Trustee  for any  losses,  liabilities,
damages,  claims or expenses of the Seller,  the Master  Servicer or the Trustee
arising  from  the  Trust  Administrator's  willful  misfeasance,  bad  faith or
negligence in connection with such preparation.

Notwithstanding  anything in this Agreement to the contrary,  each of the Master
Servicer,  the Trust Administrator 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,  the Trust  Administrator 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 Trust  Administrator  shall make a Periodic  Advance as
required by Section  3.03 hereof;  PROVIDED,  HOWEVER,  the Trust  Administrator
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  Trust  Administrator  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.

     Section 8.17 TRUST ADMINISTRATOR COVENANTS CONCERNING YEAR 2000 COMPLIANCE.

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

                                   ARTICLE IX

                                   TERMINATION

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

Subject to Section 9.02, the respective  obligations and responsibilities of the
Seller,  the Master Servicer,  the Trust  Administrator  and the Trustee created
hereby  (other than the  obligation of the Trust  Administrator  to make certain
payments  after  the  Final  Distribution  Date  to  Certificateholders  and the
obligation of the Master  Servicer to send certain  notices as  hereinafter  set
forth and the tax  reporting  obligations  under  Sections 4.05 and 8.14 hereof)
shall  terminate  upon  the  last  action  required  to be  taken  by the  Trust
Administrator  on the  Final  Distribution  Date  pursuant  to this  Article  IX
following  the earlier of (i) the purchase by the Seller of all  Mortgage  Loans
and all property acquired in respect of any Mortgage Loan remaining in the Trust
Estate at a price equal to the sum of (x) 100% of the unpaid  principal  balance
of each  Mortgage  Loan  (other  than any REO  Mortgage  Loan)  as of the  Final
Distribution  Date,  and (y) the fair  market  value of the  Mortgaged  Property
related to any REO Mortgage Loan (as determined by the Master Servicer as of the
close of business on the third  Business Day next  preceding the date upon which
notice of any such  termination is furnished to  Certificateholders  pursuant to
the third paragraph of this Section 9.01),  plus any accrued and unpaid interest
through the last day of the month  preceding  the month of such  purchase at the
applicable Mortgage Interest Rate less any Fixed Retained Yield on each Mortgage
Loan  (including  any REO  Mortgage  Loan) and (ii) the final  payment  or other
liquidation  (or any advance with  respect  thereto) of the last  Mortgage  Loan
remaining in the Trust Estate  (including  for this purpose the discharge of any
Mortgagor  under a defaulted  Mortgage Loan on which a Servicer is not obligated
to foreclose due to environmental impairment) or the disposition of all property
acquired upon  foreclosure  or deed in lieu of foreclosure of any Mortgage Loan;
provided,  HOWEVER,  that in no event shall the trust  created  hereby  continue
beyond the  expiration  of 21 years from the death of the last  survivor  of the
descendants  of Joseph P. Kennedy,  the late  ambassador of the United States to
the Court of St. James, living on the date hereof.

The right of the Seller to purchase all the assets of the Trust Estate  pursuant
to clause  (i) of the  preceding  paragraph  are  subject  to  Section  9.02 and
conditioned upon the Pool Scheduled  Principal  Balance of the Mortgage Loans as
of the Final  Distribution  Date being less than the amount set forth in Section
11.22.  In the case of any  purchase by the Seller  pursuant to said clause (i),
the Seller shall provide to the Trust  Administrator the certification  required
by Section 3.04 and the Trust  Administrator  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 Trust  Administrator
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 Trust Administrator (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 Trust  Administrator
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  Trust
Administrator  therein  specified.  If the Master  Servicer is obligated to give
notice to  Certificateholders  as  aforesaid,  it shall give such  notice to the
Trust  Administrator  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 Trust  Administrator
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 Trust  Administrator  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 Trust  Administrator  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 Trust
Administrator  (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 Trust Administrator 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 Trust  Administrator 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 Trust
      Administrator  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.

This  Agreement or any  Custodial  Agreement may be amended from time to time by
the  Seller,  the Master  Servicer,  the Trust  Administrator  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 and the Trust  Administrator  have 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, the Trust Administrator 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,  neither the Trustee
nor the Trust  Administrator  shall 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 Trust Administrator 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 Trust Administrator may prescribe.

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,  the Trust Administrator 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 Trust Administrator.

     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 Trust  Administrator,  but only
upon  direction  accompanied  by an Opinion  of Counsel to the effect  that such
recordation   materially   and   beneficially   affects  the  interests  of  the
Certificateholders.

For the purpose of  facilitating  the  recordation  of this  Agreement as herein
provided and for other purposes,  this Agreement may be executed  simultaneously

an  original,  and  such  counterparts  shall  constitute  but one and the  same
instrument.

     Section 10.03   LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

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 Trust  Administrator  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 Trust  Administrator  to
institute such action, suit or proceeding in its own name as Trust Administrator
hereunder  and shall have  offered to the Trust  Administrator  such  reasonable
indemnity as it may require  against the cost,  expenses and  liabilities  to be
incurred therein or thereby, and the Trust Administrator,  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 Trust Administrator,  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 Trust
Administrator  shall be entitled to such relief as can be given either at law or
in equity.

an opinion of counsel  acceptable to and in form and substance  satisfactory  to
the Trust  Administrator and the Seller that such transfer is exempt (describing
the applicable  exemption and the basis therefor) from or is being made pursuant

connection with any such transfer, the Trust Administrator 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 Trust  Administrator  and the Seller with respect to certain  matters and

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 Trust
Administrator,  the Seller, the Master Servicer,  and any Paying Agent acting on
behalf of the Trust  Administrator  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 Trust  Administrator 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 Trust Administrator
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 February 25, 1999, and based on its issue price of
60.18700%, including accrued interest, and a stated redemption price at maturity
equal to its initial principal  balance,  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
350% SPA (as defined in the Prospectus  Supplement  dated February 17, 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  39.81300000%;  and (ii) the annual
yield to maturity of this  Certificate,  compounded  monthly,  is  approximately
13.83%. There is no short first accrual period.

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

THIS CERTIFIES THAT  ____________________________ is the registered owner of the

the  Holders  of the Class  B-6  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 February 25, 1999 (the  "Agreement")  among
the Seller,  Norwest Bank Minnesota,  National  Association,  as master servicer
(the "Master Servicer"),  First Union National Bank, as trust administrator (the
"Trust  Administrator")  and the United  States  Trust  Company of New York,  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-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 6.000% per annum. The
amount of  interest  which  accrues  on this  Certificate  in any month  will be
subject to reduction with respect to any  Non-Supported  Interest  Shortfall and
the  interest  portion of certain  Realized  Losses  allocated  to the Class B-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

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 Trust Administrator for that purpose in the notice of final distribution.

exempt from the  registration  requirements  of the  Securities  Act of 1933, as
amended,  and any applicable state securities laws or is made in accordance with
said Act and laws.  In the event that such a  transfer  is desired to be made by
the Holder hereof,  (i) the transferee will be required to execute an investment
letter in the form described in the Agreement and (ii) if such transfer is to be
made within  three  years from the later of (a) the date of initial  issuance of
the  Certificates  or (b) the last  date on which the  Seller  or any  affiliate
thereof was a Holder of the Certificates proposed to be transferred,  and unless
such transfer is made in reliance on Rule 144A of the Securities Act of 1933, as
amended, the Trust Administrator or the Seller may require the Holder to deliver
an opinion of counsel  acceptable to and in form and substance  satisfactory  to
the Trust  Administrator 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 Trust
Administrator,  the Seller, the Master Servicer,  and any Paying Agent acting on
behalf of the Trust  Administrator  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 Trust  Administrator 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 Trust Administrator
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 February 25, 1999, and based on its issue price of
22.11900%, including accrued interest, and a stated redemption price at maturity
equal to its initial principal  balance,  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
350% SPA (as defined in the Prospectus  Supplement  dated February 17, 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  77.88100000%;  and (ii) the annual
yield to maturity of this  Certificate,  compounded  monthly,  is  approximately
36.59%. There is no short first accrual period.

                      NORWEST ASSET SECURITIES CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATES
                                  SERIES 1999-6

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 Trust  Administrator,
such advances are  reimbursable  to such  Servicer,  the Master  Servicer or the
Trust  Administrator  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 Trust
Administrator,  as  applicable,  of advances made by such  Servicer,  the Master
Servicer or the Trust Administrator.

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,  the Trust  Administrator  and the Trustee and the
rights of the Certificateholders  under the Agreement at any time by the Seller,
the Master Servicer, the Trust Administrator 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 Trust  Administrator,  duly  endorsed by, or
accompanied  by an assignment  in the form below or other written  instrument of
transfer in form  satisfactory  to the Trust  Administrator  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 Trust Administrator 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 Trust  Administrator,  the Trustee and the
Certificate  Registrar,  and any agent of the Seller,  the Master Servicer,  the
Trust  Administrator,  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 Trust Administrator,
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 Trust  Administrator 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.

            Section  6.04  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 Trust Administrator.

            Section 6.05  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 6.06 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 VII

Concerning the Custodian

            Section   7.01   CUSTODIAN   A  BAILEE   AND   AGENT  OF  THE  TRUST
ADMINISTRATOR.  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 Trust Administrator,  holds
such documents for the benefit of  Certificateholders  and undertakes to perform
such  duties  and  only  such  duties  as are  specifically  set  forth  in this
Agreement.  Except upon  compliance  with the  provisions of Section 2.5 of this
Agreement, no Mortgage Note, Mortgage or other document constituting a part of a
Custodial  File shall be delivered by the  Custodian to the Seller or the Master
Servicer or otherwise released from the possession of the Custodian.

            Section 7.02 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 7.03  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 7.04 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 7.05 CUSTODIAN MAY RESIGN;  TRUST  ADMINISTRATOR  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 Trust
Administrator  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 Trust Administrator 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 Trust Administrator may remove the Custodian at any time. In such event, the
Trust Administrator shall appoint, or petition a court of competent jurisdiction
to appoint, a successor Custodian hereunder.  Any successor Custodian shall be a
depository institution subject to supervision or examination by federal or state
authority  and shall be able to  satisfy  the other  requirements  contained  in
Section 3.7.

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

            Section 7.06 MERGER OR CONSOLIDATION  OF CUSTODIAN.  Any Person into
which  the  Custodian  may be  merged  or  converted  or  with  which  it may be
consolidated,   or  any  Person   resulting  from  any  merger,   conversion  or
consolidation to which the Custodian shall be a party, or any Person  succeeding
to the  business  of the  Custodian,  shall be the  successor  of the  Custodian
hereunder,  without the  execution  or filing of any paper or any further act on
the  part  of  any  of the  parties  hereto,  anything  herein  to the  contrary
notwithstanding.

            Section 7.07 REPRESENTATIONS OF THE CUSTODIAN.  The Custodian hereby
represents  that  it is a  depository  institution  subject  to  supervision  or
examination by a federal or state authority,  has a combined capital and surplus
of at least  $10,000,000 and is qualified to do business in the  jurisdiction in
which it will hold any Custodian File.

Servicer  nor the Trust  Administrator  shall  enter into any  amendment  hereof
except  as  permitted  by  the  Pooling  and  Servicing  Agreement.   The  Trust
Administrator  shall give prompt  notice to the  Custodian  of any  amendment or
supplement to the Pooling and Servicing Agreement and furnish the Custodian with
written copies thereof.

            SECTION  8.03  GOVERNING  LAW.  THIS  AGREEMENT  SHALL  BE  DEEMED A
CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND
ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

            Section 8.04  RECORDATION OF AGREEMENT.  To the extent  permitted by
applicable  law, this  Agreement is subject to  recordation  in all  appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated,  and in any other  appropriate  public  recording office or elsewhere,
such  recordation  to be effected by the Master  Servicer  and at its expense on
direction by the Trust Administrator,  but only upon direction accompanied by an
Opinion  of  Counsel  to  the  effect  that  such  recordation   materially  and
beneficially affects the interests of the Certificateholders.

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

            Section 8.05  SEVERABILITY OF PROVISIONS.  If any one or more of the
covenants,  agreements,  provisions or terms of this Agreement  shall be for any
reason whatsoever held invalid, then such covenants,  agreements,  provisions or
terms  shall be  deemed  severable  from the  remaining  covenants,  agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability  of the other provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

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

foregoing (other than an instrumentality if all of its activities are subject to

governmental entity), any cooperative organization furnishing electric energy or

income tax  regardless  of the source of its income or a trust if a court within
the  United   States  is  able  to  exercise   primary   supervision   over  the
administration  of such  trust,  and one or more  such  U.S.  Persons  have  the
authority to control all substantial  decisions of such trust (or, to the extent
provided in  applicable  Treasury  regulations,  certain  trusts in existence on
August 20, 1996 which are eligible to elect to be treated as U.S. Persons).

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

            9. That the  Purchaser  consents  to the  designation  of the Master
Servicer as its agent to act as "tax  matters  person" of the REMIC  pursuant to

complete loss of such  investment.] The Purchaser is a "Qualified  Institutional

(d)___The Purchaser confirms that (a) it has received and reviewed a copy of the
Private  Placement  Memorandum dated __________ __, 19__,  relating to the Class

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

(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

satisfactory to the Seller and the Trust  Administrator  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 Trust Administrator,  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  Trust   Administrator  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 Trust  Administrator shall require, in
order  to  assure  compliance  with  such  laws,  that  the  Certificateholder's
prospective  transferee certify to the Seller and the Trust  Administrator as to

      retirement  arrangement  subject  to  Title I of the  Employee  Retirement
      Income Security Act of 1974, as amended, ("ERISA"), or Section 4975 of the

      agent acting on behalf of a Plan,  or a person  utilizing  the assets of a
      Plan or (ii) if the Purchaser is an insurance  company,  (A) the source of
      funds used to  purchase  the Class [B-1]  [B-2]  [B-3]  Certificate  is an
      "insurance  company  general  account" (as such term is defined in Section
      V(e) of Prohibited  Transaction  Class Exemption  95-60 ("PTE 95-60"),  60
      Fed.  Reg.  35925 (July 12,  1995),  (B) there is no Plan with  respect to

      provisions  of ERISA,  the Code or Similar  Law and will not  subject  the

Section 2.01      REPORTS AND NOTICES.

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

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

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

                       COLLATERAL FUND; SECURITY INTEREST

Upon receipt from the Purchaser of the initial  amount  required to be deposited

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  1999-6.  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.
