ITEM 5.  Other Events
         ------------

     On February 26, 1997,  Norwest  Asset  Securities  Corporation,  a Delaware
corporation (the "Registrant"),  sold Mortgage Pass-Through Certificates, Series
1997-3,  Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class
A-7,  Class  A-PO,  Class A-R,  Class M,  Class B-1 and Class B-2 (the  "Offered
Certificates"),    having   an   aggregate   original   principal   balance   of
$198,507,952.59.  The Offered Certificates were issued pursuant to a Pooling and
Servicing  Agreement,  dated as of  February  26,  1997,  among the  Registrant,
Norwest Bank Minnesota,  National  Association,  as master servicer (the "Master
Servicer" or "Norwest  Bank") and First Union National Bank of North Carolina as
trustee  (the  "Agreement"),  a copy of which is  filed  as an  exhibit  hereto.
Mortgage  Pass-Through  Certificates,  Series  1997-3,  Class B-3, Class B-4 and
Class B-5, having an aggregate initial  principal balance of $1,500,312.88  (the
"Private  Certificates"  and,  together  with  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  99.25%  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 The Prudential  Home
Mortgage  Company,  Inc. or Norwest  Mortgage,  Inc. and of employees of various
non-participant employees. The remaining undivided interests in the Trust Estate
are  evidenced  by  the  Private   Certificates,   distributions  on  which  are
subordinated to distributions on the Offered Certificates.

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

     An election  will be made to treat the Trust  Estate as a REMIC for federal
income tax purposes (the  "REMIC").  The Class A-1,  Class A-2, Class A-3, Class
A-4, Class A-5, Class A-6, Class A-7, Class A-PO, Class M, Class B-1, Class B-2,
Class B-3,  Class B-4 and Class B-5  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.

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

     In connection with such assignment,  the Seller shall, with respect to each

following the Closing  Date.  The Seller shall also cause to be delivered to the
Trustee any other  original  mortgage  loan document to be included in the Owner
Mortgage  Loan File if a copy thereof has been  delivered.  The Seller shall pay
from its own funds, without any right of reimbursement  therefor,  the amount of

not delivered to the Trustee on the Closing Date.

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

     Section 2.02. Acceptance by Trustee.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

               (v) All taxes, governmental assessments,  insurance premiums, and
water, sewer and municipal  charges,  which previously became due and owing have
been paid, or an escrow of funds has been  established,  to the extent permitted
by law, in an amount sufficient to pay for every such item which remains unpaid;
and the Seller has not  advanced  funds,  or received  any advance of funds by a
party other than the Mortgagor,  directly or indirectly  (except pursuant to any
Subsidy  Loan  arrangement)  for  the  payment  of any  amount  required  by the
Mortgage,  except for interest  accruing  from the date of the Mortgage  Note or
date of disbursement  of the Mortgage Loan proceeds,  whichever is later, to the
day which precedes by thirty days the first Due Date under the related  Mortgage
Note;

               (vi)  The  Mortgaged   Property  is  undamaged  by  water,  fire,
earthquake,  earth movement other than earthquake,  windstorm, flood, tornado or
similar  casualty  (excluding  casualty from the presence of hazardous wastes or
hazardous substances, as to which the Seller makes no representations), so as to
affect  adversely  the  value of the  Mortgaged  Property  as  security  for the
Mortgage Loan or the use for which the premises were intended and to the best of
the Seller's  knowledge,  there is no proceeding  pending or threatened  for the
total or partial condemnation of the Mortgaged Property;

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

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

improvements  which are included for the purpose of  determining  the  appraised
value of the Mortgaged  Property lie wholly within the  boundaries  and building
restriction  lines of such property and no improvements on adjoining  properties
encroach upon the Mortgaged  Property  (unless insured against under the related
title  insurance  policy);  and  to the  best  of the  Seller's  knowledge,  the
Mortgaged Property and all improvements  thereon comply with all requirements of
any applicable zoning and subdivision laws and ordinances;

               (ix) The Mortgage Loan meets, or is exempt from, applicable state
or federal laws,  regulations and other  requirements,  pertaining to usury, and
the Mortgage Loan is not usurious;

               (x) To the  best  of the  Seller's  knowledge,  all  inspections,

occupancy of the same, including,  but not limited to, certificates of occupancy
and  fire  underwriting  certificates,  have  been  made or  obtained  from  the
appropriate authorities;

               (xi)  All  payments  required  to be  made  up to  the  Due  Date
immediately preceding the Cut-Off Date for such Mortgage Loan under the terms of
the related  Mortgage Note have been made and no Mortgage Loan had more than one
delinquency in the 12 months preceding the Cut-Off Date;

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

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

               (xiv)  The  proceeds  of  the  Mortgage  Loans  have  been  fully
disbursed,  there is no requirement for future  advances  thereunder and any and
all requirements as to completion of any on-site or off-site improvements and as

for  escrow  funds  for  exterior  items  which  could not be  completed  due to
weather);  and all costs,  fees and  expenses  incurred  in  making,  closing or
recording the Mortgage Loan have been paid,  except  recording fees with respect
to Mortgages not recorded as of the Closing Date;

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

               (xvi) The  Mortgaged  Property  securing  each  Mortgage  Loan is
insured by an insurer  acceptable to FNMA or FHLMC against loss by fire and such
hazards as are covered under a standard  extended  coverage  endorsement,  in an
amount which is not less than the lesser of 100% of the  insurable  value of the
Mortgaged  Property and the outstanding  principal balance of the Mortgage Loan,
but in no event less than the minimum amount  necessary to fully  compensate for
any damage or loss on a replacement  cost basis; if the Mortgaged  Property is a
condominium unit, it is included under the coverage afforded by a blanket policy
for the project;  if upon  origination of the Mortgage Loan, the improvements on
the Mortgaged Property were in an area identified in the Federal Register by the
Federal  Emergency  Management  Agency as having special flood hazards,  a flood
insurance  policy  meeting the  requirements  of the current  guidelines  of the
Federal  Insurance  Administration  is in  effect  with a  generally  acceptable
insurance carrier, in an amount representing coverage not less than the least of
(A) the  outstanding  principal  balance  of the  Mortgage  Loan,  (B) the  full
insurable  value  of the  Mortgaged  Property  and (C)  the  maximum  amount  of
insurance which was available  under the Flood Disaster  Protection Act of 1973;
and each  Mortgage  obligates  the  Mortgagor  thereunder  to maintain  all such
insurance at the Mortgagor's cost and expense;

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

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

               (xix)  Each  Mortgage  Note  is  payable  in  monthly   payments,
resulting in complete  amortization of the Mortgage Loan over a term of not more
than 360 months;

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

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

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

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

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

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

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

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

     Section 2.04. Execution and Delivery of Certificates.

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

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

     The Seller hereby designates the Subclasses of Class A Certificates  (other
than the Class A-R Certificate),  the Class M Certificates and the Subclasses of
Class B  Certificates  as  classes  of  "regular  interests"  and the  Class A-R
Certificate  as the single  class of  "residual  interest"  in the REMIC for the
purposes of Code Sections 860G(a)(1) and 860G(a)(2),  respectively.  The Closing
Date is hereby  designated  as the "Startup Day" of the REMIC within the meaning
of Code Section  860G(a)(9).  The "latest possible maturity date" of the regular
interests  in the  REMIC  is  March  25,  2027  for  purposes  of  Code  Section
860G(a)(1).

          (a) The Master  Servicer  shall  establish  and maintain a Certificate
Account for the deposit of funds received by the Master Servicer with respect to
the Mortgage Loans serviced by the Servicer pursuant to the Servicing Agreement.
Such account  shall be maintained as an Eligible  Account.  The Master  Servicer

Certificate Account and of any change in the location thereof.

          (b) The Master Servicer shall deposit into the Certificate  Account on

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

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

     Section 3.02. Permitted Withdrawals from the Certificate Account.

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

               (i) to  reimburse  the  Trustee  or  the  Servicer  for  Periodic
Advances  made by the  Trustee  pursuant  to  Section  3.03(a)  or the  Servicer
pursuant to the Servicing Agreement with respect to previous Distribution Dates,
such right to  reimbursement  pursuant to this  subclause  (i) being  limited to
amounts received on or in respect of particular  Mortgage Loans (including,  for
this purpose, Liquidation Proceeds, REO Proceeds and proceeds from the purchase,
sale,  repurchase or  substitution  of Mortgage Loans pursuant to Sections 2.02,
2.03, 3.08 or 9.01) respecting which any such Periodic Advance was made;

               (ii) to  reimburse  the  Servicer or the Trustee for any Periodic
Advances  determined  in good  faith  to  have  become  Nonrecoverable  Advances
provided,  however,  that any portion of  Nonrecoverable  Advances  representing
Fixed Retained Yield shall be reimbursable only from amounts  constituting Fixed
Retained Yield and not from the assets of the Trust Estate;

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

               (iv) from any  Mortgagor  payment on account of interest or other
recovery  (including  Net REO  Proceeds)  with respect to a particular  Mortgage
Loan, to pay the Master  Servicing Fee with respect to such Mortgage Loan to the
Master Servicer;

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

               (vi) to pay to the Seller or other purchaser with respect to each
Mortgage Loan or property  acquired in respect thereof that has been repurchased
or replaced  pursuant to Section 2.02 or 2.03 or  auctioned  pursuant to Section
3.08 or to pay to the Master  Servicer  with  respect to each  Mortgage  Loan or
property acquired in respect thereof that has been purchased pursuant to Section
3.08 or 9.01, all amounts received thereon and not required to be distributed as
of the date on which the  related  repurchase  or  purchase  price or  Scheduled
Principal Balance was determined;

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

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

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

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

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

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

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

     Section 3.03. Advances by Trustee.

          (a) In the  event the  Servicer  fails to make any  required  Periodic
Advances  of  principal  and  interest  on a Mortgage  Loan as  required  by the
Servicing Agreement prior to the Distribution Date occurring in the month during
which such Periodic Advance is due, the Trustee shall, to the extent required by
Section 8.15, make such Periodic Advance to the extent provided hereby, provided
that the Trustee has previously  received the certificate of the Master Servicer
described in the following  sentence.  The Master  Servicer shall certify to the
Trustee  with respect to any such  Distribution  Date (i) the amount of Periodic
Advances required of the Servicer (ii) the amount actually  advanced,  (iii) the
amount that the Trustee is required to advance  hereunder  and (iv)  whether the
Master  Servicer has determined  that it reasonably  believes that such Periodic
Advance is a  Nonrecoverable  Advance.  Amounts advanced by the Trustee shall be
deposited  in  the  Certificate  Account  on  the  related   Distribution  Date.
Notwithstanding  the  foregoing,  the Trustee  will not be  obligated  to make a
Periodic Advance that it reasonably believes to be a Nonrecoverable Advance. The
Trustee may conclusively  rely for any  determination to be made by it hereunder
upon the determination of the Master Servicer as set forth in its certificate.

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

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

          (d) Except as provided in Section  3.03(a) and (b), the Trustee  shall
not be required to pay or advance any amount which the  Servicer  was  required,
but failed, to deposit in the Certificate Account.

     Section 3.04. Trustee to Cooperate; Release of Owner Mortgage Loan Files.

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

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

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

     Section 3.05. Reports to the Trustee; Annual Compliance Statements.

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

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

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

     The  Master   Servicer   shall  ensure  that  each  REO  Mortgage  Loan  is
administered  by the 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 the  Servicer  is unable to dispose of any REO  Mortgage  Loan
within the period mandated by the Servicing Agreement, the Master Servicer shall
monitor the Servicer to verify that such REO  Mortgage  Loan is auctioned to the
highest bidder within the period so specified.  In the event of any such sale of
REO  Mortgage  Loan,  the Trustee  shall,  at the written  request of the Master
Servicer and upon being supported with appropriate  forms therefor,  within five
Business Days of the deposit by the Master Servicer of the proceeds of such sale
or auction into the Certificate Account,  release or cause to be released to the
entity  identified by the Master  Servicer the related Owner  Mortgage Loan File
and Servicer  Mortgage Loan File and shall execute and deliver such  instruments
of transfer or assignment,  in each case without recourse, as shall be necessary
to vest in the auction  purchaser title to the REO Mortgage Loan and the Trustee
shall have no further  responsibility  with regard to such Owner  Mortgage  Loan
File or Servicer  Mortgage Loan File.  Neither the Trustee,  the Master Servicer
nor the 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 Agreement,  Modification of Standard
Provisions.

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

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

          (c)(i) Notwithstanding  anything to the contrary in this Section 3.07,
the  Master  Servicer  from  time  to  time  may,  without  the  consent  of any
Certificateholder  or the  Trustee,  enter into an  amendment  to the  Servicing
Agreement for the purpose of changing the applicable Remittance Date to the 18th
day of each  month  (or if  such  day is not a  Business  Day,  on the  previous
Business Day).

          (ii) The Master  Servicer  may direct  the  Servicer  to enter into an
amendment to the  Servicing  Agreement  for the  purposes  described in Sections
3.07(c)(i) 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 the Servicer and the  performance  by the Servicer of all
services,  duties,  responsibilities  and obligations that are to be observed or
performed by the Servicer  under the  Servicing  Agreement.  In  performing  its
obligations hereunder, the Master Servicer shall act in a manner consistent with
Accepted   Master   Servicing   Practices   and  with  the   Trustee's  and  the
Certificateholders'  reliance on the Master Servicer, and in a manner consistent
with the terms and provisions of any insurance  policy required to be maintained
by the  Master  Servicer  or the  Servicer  pursuant  to this  Agreement  or the
Servicing  Agreement.  The  Master  Servicer  acknowledges  that prior to taking
certain actions required to service the Mortgage Loans, the 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 the Servicer with
certain provisions of the Servicing Agreement. In each such instance, the Master
Servicer  shall  promptly  instruct  the  Servicer or  otherwise  respond to the
Servicer's  request.  In no event will the Master Servicer instruct the Servicer
to take  any  action,  give any  consent  to  action  by the  Servicer  or waive
compliance by the Servicer with any provision of the Servicing  Agreement if any
resulting  action or failure to act would be inconsistent  with the requirements
of the Rating  Agencies that rated the  Certificates  or would otherwise have an
adverse  effect on the  Certificateholders.  Any such  action or  failure to act
shall be deemed to have an  adverse  effect  on the  Certificateholders  if such
action or  failure to act either  results in (i) the  downgrading  of the rating
assigned by any Rating  Agency to the  Certificates,  (ii) the loss by the Trust
Estate of REMIC status for federal  income tax purposes or (iii) the  imposition
of any Prohibited Transaction Tax or any federal taxes on the REMIC or the Trust
Estate.  The Master  Servicer  shall have full power and  authority  in its sole
discretion  to take any  action  with  respect  to the  Trust  Estate  as may be
necessary or advisable to avoid the  circumstances  specified  including  clause
(ii) or (iii) of the preceding sentence.

     For the purposes of determining whether any modification of a Mortgage Loan
shall be  permitted  by the Trustee or the Master  Servicer,  such  modification
shall be  construed as a  substitution  of the  modified  Mortgage  Loan for the
Mortgage  Loan  originally  deposited  in the  Trust  Estate  if it  would  be a
"significant  modification"  within the  meaning of Section  1.860G-2(b)  of the
regulations of the U.S.  Department of the Treasury.  No  modification  shall be
approved  unless (i) the modified  Mortgage  Loan would  qualify as a Substitute
Mortgage Loan under Section 2.02 and (ii) with respect to any modification  that
occurs more than three  months after the Closing Date and is not the result of a
default or a reasonably  foreseeable  default under the Mortgage Loan,  there is
delivered  to the  Trustee an Opinion  of Counsel  (at the  expense of the party
seeking to modify the Mortgage Loan) to the effect that such modification  would
not be treated as giving rise to a new debt  instrument  for federal  income tax
purposes as described in the preceding sentence.

     During the term of this Agreement,  the Master Servicer shall consult fully
with the 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  the  Servicer  to perform  and  observe  the  covenants,
obligations and conditions to be performed or observed by it under the Servicing
Agreement.

     The relationship of the Master Servicer to the Trustee under this Agreement
is intended by the parties to be that of an independent  contractor and not that
of a joint venturer, partner or agent.

     The Master  Servicer  shall  administer  the Trust  Estate on behalf of the
Trustee  and shall have full power and  authority,  acting  alone or (subject to
Section  6.06) through one or more  subcontractors,  to do any and all things in
connection  with such  administration  which it may deem necessary or desirable.
Upon the execution and delivery of this Agreement,  and from time to time as may
be required  thereafter,  the Trustee shall  furnish the Master  Servicer or its
subcontractors  with any powers of attorney  and such other  documents as may be
necessary  or  appropriate  to  enable  the  Master  Servicer  to carry  out its
administrative duties hereunder.

     The Seller shall be entitled,  at its option,  to repurchase  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;  provided,  however,  that the Cut-Off Date Principal
Balances of the Mortgage Loans repurchased  pursuant to this provision shall not
exceed 2.5% of the Cut-Off  Date  Aggregate  Principal  Balance of the  Mortgage
Loans. 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,  less any Fixed Retained Yield for such Mortgage Loan,
through  the last day of the month in which  such  repurchase  occurs.  Upon the
receipt of such purchase price, the Master Servicer shall provide to the Trustee
the certification required by Section 3.04 and the Trustee and the Custodian, if
any, shall promptly  release to the Seller the Owner Mortgage Loan File relating
to the Mortgage Loan being repurchased.

     In the event  that (i) the  Master  Servicer  determines  at any time that,
notwithstanding the representations and warranties set forth in Section 2.03(b),
any Mortgage  Loan is not a "qualified  mortgage"  within the meaning of Section
860G of the  Code  and (ii)  the  Master  Servicer  is  unable  to  enforce  the
obligation of the Seller to purchase such Mortgage Loan pursuant to Section 2.02
within two months of such  determination,  the Master  Servicer shall cause such
Mortgage  Loan to be auctioned  to the highest  bidder and sold out of the Trust
Estate no later than the date 90 days after such determination.  In the event of
any such sale of a Mortgage Loan, the Trustee shall,  at the written  request of
the Master  Servicer and upon being supported with  appropriate  forms therefor,
within five Business Days of the deposit by the Master  Servicer of the proceeds
of such auction into the Certificate Account, release or cause to be released to
the entity  identified by the Master  Servicer the related  Owner  Mortgage Loan
File and  Servicer  Mortgage  Loan  File and  shall  execute  and  deliver  such
instruments of transfer or assignment,  in each case without recourse,  as shall
be necessary to vest in the auction purchaser title to the Mortgage Loan and the
Trustee shall have no further  responsibility with regard to such Owner Mortgage
Loan File or  Servicer  Mortgage  Loan File.  Neither  the  Trustee,  the Master
Servicer  nor the  Servicer,  acting  on behalf of the  Trustee,  shall  provide
financing from the Trust Estate to any purchaser of a Mortgage Loan.

     The Master  Servicer,  on behalf of the  Trustee,  shall,  pursuant  to the
Servicing Agreement, object to the foreclosure upon, or other related conversion
of the ownership  of, any  Mortgaged  Property by the Servicer if (i) the Master
Servicer  believes such Mortgaged  Property may be contaminated with or affected
by hazardous wastes or hazardous  substances or (ii) the 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 B  Subclass  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 the Servicer to the extent provided in the 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 Agreement.

     Upon the  occurrence  of any event for which the Servicer may be terminated
pursuant to the 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  the  Servicing   Agreement,
describing the circumstances surrounding such event and recommending what action
should be taken by the  Trustee  with  respect  to the  Servicer.  If the Master
Servicer  recommends  that the  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  the  Servicing
Agreement.  Notwithstanding  the  foregoing,  in the event that (i) the Servicer
fails to make any advance, as a consequence of which the Trustee is obligated to
make an advance  pursuant  to Section  3.03 and (ii) the  Trustee  provides  the
Servicer  written  notice of the failure to make such  advance and such  failure
shall continue  unremedied for a period of 15 days after receipt of such notice,
the Trustee shall terminate the Servicing  Agreement without the  recommendation
of the Master Servicer. The Master Servicer shall indemnify the Trustee and hold
it harmless from and against any and all claims, liabilities, costs and expenses
(including,  without limitation,  reasonable attorneys' fees) arising out of, or
assessed  against the Trustee in connection  with  termination  of the Servicing
Agreement at the direction of the Master Servicer. If the Trustee terminates the
Servicing Agreement, the Trustee may enter into a substitute Servicing Agreement
with the Master Servicer or, at the Master Servicer's  nomination,  with another
mortgage loan service company acceptable to the Trustee, the Master Servicer and
each Rating Agency under which the Master Servicer or such substitute  servicer,
as  the  case  may  be,  shall  assume,  satisfy,  perform  and  carry  out  all
liabilities,  duties,  responsibilities  and  obligations  that  are to  be,  or
otherwise  were  to have  been,  satisfied,  performed  and  carried  out by the
Servicer  under  the  terminated  Servicing  Agreement.  Until  such time as the
Trustee  enters  into a  substitute  servicing  agreement  with  respect  to the
Mortgage Loans  previously  serviced by the 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 the  Servicer  under the
terminated Servicing  Agreement.  However, in no event shall the Master Servicer
be deemed to have assumed the obligations of the Servicer to advance payments of
principal and interest on a delinquent  Mortgage Loan. 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 the Servicer would have been entitled if the Servicing  Agreement with the
Servicer had not been terminated.

     Section 3.10. 1934 Act Reports.

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

Unpaid Interest Shortfall;

     tenth,  to the  Class  B-1  Certificates  in an  amount up to the Class B-1
Optimal Principal Amount;  provided,  however,  that the amount distributable to

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

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 or
Subclass (other than the Class A-R  Certificate)  has been reduced to zero, such
Class or Subclass 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 the 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 B Subclass will be allocated pro
rata based on principal  balance among the Class A Certificates  (other than the
Class A-PO Certificates), the Class M Certificates and any Class B Subclass with
a lower  numerical  designation and the amount of the Principal  Adjustment,  if
any,  attributable  to  the  Class  M  Certificates  will  be  allocated  to the
Subclasses of Class A Certificates  (other than the Class A-PO Certificates) pro
rata based on the Class A Subclass Principal Balances.

          (b) On each  Distribution Date occurring prior to the Cross-Over Date,
an  amount  equal  to  the  Accrual   Distribution  Amount,  if  any,  for  such
Distribution  Date will be allocated in reduction of the  principal  balances of
the  Class  A-1,  Class  A-2,  Class  A-3,  Class  A-4,  Class A-5 and Class A-6
Certificates, concurrently, as follows:

               (i) 34.1981000000%,  sequentially, to the Class A-1 and Class A-6
Certificates,  in that order,  until the Class A Subclass  Principal  Balance of
each such Subclass has been reduced to zero;

               (ii) 65.8019000000%,  sequentially,  to the Class A-2, Class A-3,
Class A-4, Class A-5 and Class A-6 Certificates,  in that order, until the Class
A Subclass Principal Balance of each such Subclass has been reduced to zero.

     On each Distribution Date occurring prior to the Cross-Over Date, the Class
A Non-PO  Principal  Amount will be allocated among and distributed in reduction
of the  Class  A  Subclass  Principal  Balances  of the  Subclasses  of  Class A
Certificates  (other  than the Class A Subclass  Principal  Balance of the Class
A-PO Certificates) as follows:

     first, to the Class A-7 Certificates, up to the Class A-7 Priority Amount;

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

     third, concurrently, as follows:

               (i) 34.1980893034%,  sequentially, to the Class A-1 and Class A-6
Certificates,  in that order,  until the Class A Subclass  Principal  Balance of
each such Subclass has been reduced to zero;

               (ii) 65.8019106966%,  sequentially,  to the Class A-2. Class A-3,
Class A-4, Class A-5 and Class A-6 Certificates,  in that order, until the Class
A Subclass Principal Balance of each such Subclass has been reduced to zero; and

     fourth,  to the Class  A-7  Certificates,  without  regard to the Class A-7
Priority Amount,  until the Class A Subclass  Principal Balance thereof has been
reduced to zero.

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

          (d) (i) For purposes of determining  whether the Subclasses 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 M Fractional  Interest is less than
the Original  Class M Fractional  Interest and the Class M Principal  Balance is
greater than zero,  the Class B-1, Class B-2, Class B-3, Class B-4 and Class B-5
Certificates shall not be eligible to receive distributions of principal; or

                    (B) 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 and Class B-5
Certificates shall not be eligible to receive distributions of principal; or

                    (C) 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  and  Class  B-5
Certificates shall not be eligible to receive distributions of principal; or

                    (D) 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 and Class B-5 Certificates shall not
be eligible to receive distributions of principal; or

                    (E) 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  Certificates  shall not be eligible
to receive distributions of principal.

               (ii)  Notwithstanding the foregoing,  if on any Distribution Date
the aggregate  distributions  to Holders of the Class M Certificates  and/or the
Subclasses  of  Class  B  Certificates  entitled  to  receive  distributions  of
principal would reduce the Class M Principal Balance and/or the Class B Subclass
Principal Balances of the Class M Certificates  and/or the Subclasses of Class B
Certificates  entitled to receive  distributions  of principal below zero, first
the  Class M  Prepayment  Percentage  and/or  the  Class B  Subclass  Prepayment
Percentage of any affected Class B Subclass for such Distribution Date beginning
with the affected  Subclass with the lowest numerical  Subclass  designation and
then,  if  necessary,  the  Class M  Percentage  and/or  the  Class  B  Subclass
Percentage of such Subclass of the Class B  Certificates  for such  Distribution
Date shall be reduced to the respective percentages necessary to bring the Class
M Principal Balance and/or the Class B Subclass  Principal Balance of such Class
B Subclass to zero. The Class B Subclass Prepayment  Percentages and the Class B
Subclass  Percentages  of the  remaining  Class B Subclasses  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 Class M  Principal  Balance  and/or the Class B Subclass  Principal
Balances of the affected Class B Subclasses to zero; provided,  however, that if
the Class B Subclass Principal  Balances of all the Class B Subclasses  eligible
to  receive  distributions  of  principal  shall  be  reduced  to  zero  on such
Distribution  Date, the Class B Subclass  Prepayment  Percentage and the Class B
Subclass  Percentage of the Class B Subclass with the lowest numerical  Subclass
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  M  Prepayment   Percentage  and  the  Class  B  Subclass  Prepayment
Percentages  of  the  Class  B  Subclasses   having  lower  numerical   Subclass
designations,  if any, and the remainder of the Subordinated Percentage for such
Distribution  Date  minus  the sum of the  Class M  Percentage  and the  Class B
Subclass  Percentages of the Class B Subclasses having lower numerical  Subclass
designations,  if any, respectively.  Any entitlement of any Class B Subclass to
principal  payments  solely  pursuant  to this  clause (ii) shall not cause such
Subclass to be regarded as being eligible to receive principal distributions for
the purpose of applying the  definition  of its Class B Subclass  Percentage  or
Class B Subclass Prepayment Percentage.

          (e) On each Distribution  Date other than the Final  Distribution Date
(if such Final  Distribution Date is in connection with a purchase of the assets
of the Trust  Estate by the Seller),  the Paying  Agent shall,  on behalf of the
Master Servicer, from funds remitted to it by the Master Servicer, distribute to
each  Certificateholder  of record on the  preceding  Record Date (other than as
provided in Section 9.01 respecting the final distribution to Certificateholders
or  in  the  last  paragraph  of  this  Section  4.01(e)  respecting  the  final
distribution  in  respect  of any  Class  or  Subclass)  either  in  immediately
available funds by wire transfer to the account of such  Certificateholder  at a
bank  or  other  entity  having  appropriate   facilities   therefor,   if  such
Certificateholder  holds  Certificates  having a Denomination  at least equal to
that specified in Section 11.24,  and has so notified the Master Servicer or, if
applicable,  the  Paying  Agent  at  least  seven  Business  Days  prior  to the
Distribution  Date  or,  if  such  Holder  holds  Certificates  having,  in  the
aggregate,  a Denomination  less than the requisite  minimum  Denomination or if
such Holder  holds the Class 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 (based on, with respect to each
Class or Subclass,  the aggregate of the  Percentage  Interests  represented  by
Certificates of the applicable  Class or Subclass of  Certificates  held by such
Holder)  of the  Class A  Subclass  Distribution  Amount  with  respect  to each
Subclass of Class A Certificates,  the Class M Distribution  Amount with respect
to the Class M Certificates  and the Class B Subclass  Distribution  Amount with
respect to each such Subclass of Class B Certificates.

     In the event that, on any Distribution Date prior to the Final Distribution
Date,  the  Class A  Subclass  Principal  Balance  of any  Subclass  of  Class A
Certificates  (other  than the Class  A-R  Certificate),  the Class M  Principal
Balance of the Class M Certificates or the Class B Subclass Principal Balance of
any  Subclass  of Class B  Certificates  would be  reduced  to zero,  the Master
Servicer shall, as soon as practicable after the Determination  Date relating to
such Distribution Date, send a notice to the Trustee. The Trustee will then send
a notice to each  Certificateholder of such Class or Subclass with a copy to the
Certificate  Registrar,  specifying that the final  distribution with respect to
such  Class or  Subclass  will be made on such  Distribution  Date only upon the
presentation  and  surrender  of such  Certificateholder's  Certificates  at the
office or agency of the Trustee therein specified;  provided,  however, that the
failure to give such notice will not entitle a Certificateholder to any interest
beyond the interest payable with respect to such Distribution Date in accordance
with Section 4.01(a).

          (f) The Paying Agent (or if no Paying Agent is appointed by the Master
Servicer,  the Master  Servicer)  shall  withhold or cause to be  withheld  such
amounts as may be required  by the Code  (giving  full effect to any  exemptions
from  withholding  and  related  certifications  required  to  be  furnished  by
Certificateholders  and any reductions to withholding by virtue of any bilateral
tax  treaties  and any  applicable  certification  required to be  furnished  by
Certificateholders  with  respect  thereto)  from  distributions  to be  made to
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 "Non-U.S.
Person" is an individual, corporation,  partnership or other person other than a
citizen or resident of the United States,  a  corporation,  partnership 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 (i) for
taxable  years  beginning  after  December 31, 1996 (or for taxable years ending
after August 20, 1996, if the trustee has made an applicable election),  a court
within  the  United  States is able to  exercise  primary  supervision  over the
administration of such trust, and one or more United States fiduciaries have the
authority  to control all  substantial  decisions  of such trust or (ii) for all
other taxable  years,  such trust is subject to United States federal income tax
regardless of the source of its income.

     Section 4.02. Allocation of Realized Losses.

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

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

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

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

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

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

     sixth, to the Class M Certificates  until the Class M 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 or Subclass's Principal Balance.

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

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

          (d) In the event that  there is a recovery  of an amount in respect of
principal of a Mortgage Loan which had  previously  been allocated as a Realized
Loss to any Subclasses of Class A Certificates,  the Class M Certificates or any
Subclasses of Class B Certificates,  each outstanding Class or Subclass 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),  Class M 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 or Subclass on the  Distribution  Date in the month following the month in
which  such  recovery  is  received.  When the  Principal  Balance of a Class or
Subclass of Certificates  has been reduced to zero, such Class or Subclass 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 or Subclass in accordance with the preceding provisions,  each outstanding
Class  or  Subclass  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 or Subclass.

          (e) The interest portion of Excess Special Hazard Losses, Excess Fraud
Losses  and  Excess  Bankruptcy  Losses  shall be  allocated  among  the Class A
Certificates,  Class M Certificates and Class B Certificates,  pro rata based on
the Class A Interest Accrual Amount, the Class M 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  Subclasses of
Class A  Certificates  (other than the Class A-PO  Certificates)  based on their
Class A Subclass  Interest  Percentages.  Any such loss allocated to the Class B
Certificates  will be  allocated  among the  outstanding  Subclasses  of Class B
Certificates based on their Class B Subclass Interest Percentages.  In addition,
after the Class M Principal  Balance and the Class B Principal Balance have been

     Section 4.03. Paying Agent.

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

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

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

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

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

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

          (b) The Paying Agent shall  establish and maintain a Payment  Account,
which shall be a separate  trust account and an Eligible  Account,  in which the
Master  Servicer  shall  cause to be  deposited  from  funds in the  Certificate
Account  or,  to the  extent  required  hereunder,  from its own funds (i) at or

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

     Section 4.04. Statements to  Certificateholders;  Report to the Trustee and
the Seller.

independent check or verification.

     In addition to the reports  required  pursuant to this  Section  4.04,  the

conversion  in full or partial  satisfaction  of a Mortgage Loan serviced by the
Servicer, or (ii) knows or has reason to know that a Mortgaged Property has been

Mortgagors such  information as is required under Code Sections 6050H (regarding

                               THE CERTIFICATES

     Section 5.01. The Certificates.

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

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

     "Unless this  certificate is presented by an authorized  representative  of
[the Clearing  Agency] to the Trustee or its agent for registration of transfer,
exchange or payment,  and any  certificate  issued is  registered in the name of
[the  Clearing  Agency]  or  such  other  name  as  requested  by an  authorized
representative of [the Clearing Agency] and any payment is made to [the Clearing
Agency],  any transfer,  pledge or other use hereof for value or otherwise by or
to any person is wrongful  since the  registered  owner  hereof,  [the  Clearing
Agency], has an interest herein."

          (b) Upon  original  issuance,  the  Book-Entry  Certificates  shall be
issued in the form of one or more typewritten  certificates,  to be delivered to
The Depository Trust Company,  the initial Clearing Agency, by, or on behalf of,
the Seller.  Such Certificates  shall initially be registered in the Certificate
Register  in the name of the  nominee of the  initial  Clearing  Agency,  and no
Beneficial  Owner  will  receive  a  definitive  certificate  representing  such
Beneficial Owner's interest in the Book-Entry  Certificates,  except as provided
in Section 5.07.  Unless and until  definitive,  fully  registered  certificates
("Definitive  Certificates")  have been issued to Beneficial  Owners pursuant to
Section 5.07:

               (i) the provisions of this Section 5.01(b) shall be in full force
and effect;

               (ii) the Seller, the Master Servicer,  the Certificate  Registrar
and the Trustee may deal with the Clearing  Agency for all  purposes  (including
the making of  distributions  on the Book-Entry  Certificates  and the taking of
actions  by  the  Holders  of  Book-Entry   Certificates)   as  the   authorized
representative of the Beneficial Owners;

               (iii) to the extent that the  provisions of this Section  5.01(b)
conflict with any other  provisions of this  Agreement,  the  provisions of this
Section 5.01(b) shall control;

               (iv) the rights of  Beneficial  Owners  shall be  exercised  only
through the Clearing  Agency and shall be limited to those  established  by law,
the rules,  regulations  and  procedures of the Clearing  Agency and  agreements
between  such  Beneficial  Owners and the  Clearing  Agency  and/or the Clearing
Agency  Participants,  and  all  references  in this  Agreement  to  actions  by
Certificateholders shall, with respect to the Book-Entry Certificates,  refer to
actions taken by the Clearing Agency upon  instructions from the Clearing Agency
Participants,  and all references in this Agreement to  distributions,  notices,
reports  and  statements  to  Certificateholders  shall,  with  respect  to  the
Book-Entry Certificates, refer to distributions, notices, reports and statements
to the Clearing  Agency or its nominee,  as registered  holder of the Book-Entry
Certificates,  as the case may be,  for  distribution  to  Beneficial  Owners in
accordance with the procedures of the Clearing Agency; and

               (v) the initial  Clearing Agency will make  book-entry  transfers
among the Clearing Agency Participants and receive and transmit distributions of
principal and interest on the Certificates to the Clearing Agency  Participants,
for distribution by such Clearing Agency  Participants to the Beneficial  Owners
or their nominees.

     For purposes of any  provision of this  Agreement  requiring or  permitting
actions  with the  consent of, or at the  direction  of,  Holders of  Book-Entry
Certificates  evidencing  specified Voting Interests,  such direction or consent
shall be given by  Beneficial  Owners  having the  requisite  Voting  Interests,
acting through the Clearing Agency.

     Unless and until  Definitive  Certificates  have been issued to  Beneficial
Owners pursuant to Section 5.07, copies of the reports or statements referred to
in Section 4.04 shall be available to Beneficial  Owners upon written request to
the Trustee at the Corporate Trust Office.

     Section 5.02. Registration of Certificates.

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

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

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

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

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

          (b) No  transfer  of a Class B-3,  Class B-4 or Class B-5  Certificate
shall be made unless the  registration  requirements  of the  Securities  Act of
1933, as amended, and any applicable State securities laws are complied with, or
such transfer is exempt from the  registration  requirements  under said Act and
laws.  In the event that a transfer is to be made in reliance  upon an exemption
from said Act or laws,  (i) unless  such  transfer  is made in  reliance on Rule
144A, the Trustee or the Seller may, if such transfer is to be made within three
years after the later of (i) the date of the  initial  sale of  Certificates  or
(ii) the last date on which the Seller or any affiliate  thereof was a Holder of
the Certificates  proposed to be transferred,  require a Class B-3, Class B-4 or
Class B-5  Certificateholder  to deliver a written Opinion of Counsel acceptable
to and in form and substance  satisfactory to the Trustee and the Seller, to the
effect that such transfer may be made pursuant to an exemption,  describing  the
applicable exemption and the basis therefor,  from said Act and laws or is being
made  pursuant to said Act and laws,  which  Opinion of Counsel  shall not be an
expense of the Trustee, the Seller or the Master Servicer,  and (ii) the Trustee
shall  require the  transferee  to execute an  investment  letter in the form of
Exhibit J hereto  certifying to the Seller and the Trustee the facts surrounding
such transfer,  which investment  letter shall not be an expense of the Trustee,
the Seller or the Master Servicer. The Holder of a Class B-3, Class B-4 or Class
B-5 Certificate  desiring to effect such transfer  shall,  and does hereby agree
to, indemnify the Trustee,  the Seller, the Master Servicer and any Paying Agent
acting on behalf of the  Trustee  against any  liability  that may result if the
transfer  is not so exempt or is not made in  accordance  with such  federal and
state  laws.  Neither  the Seller  nor the  Trustee  is under an  obligation  to
register the Class B-3,  Class B-4 or Class B-5  Certificates  under said Act or
any other securities law.

          (c) No  transfer  of a Class M or  Class B  Certificate  shall be made
unless the Trustee  shall have  received  (i) a  representation  letter from the
transferee  in the form of Exhibit J hereto,  in the case of a Class B-3,  Class
B-4 or Class B-5 Certificate, or in the form of Exhibit K hereto, in the case of
a Class M, Class B-1 or Class B-2  Certificate,  to the effect  that  either (a)
such  transferee  is not an  employee  benefit  plan  subject  to the  fiduciary
responsibility provisions of ERISA or Code Section 4975, or a governmental plan,
as defined in Section 3(32) of ERISA, or subject to any federal,  state or local
law  ("Similar  Law")  which is to a material  extent  similar to the  foregoing
provisions  of ERISA or the Code  (collectively,  a "Plan")  and is not a person
acting on behalf of or using the assets of any such Plan,  which  representation
letter shall not be an expense of the Trustee, the Seller or the Master Servicer
or (b) if such transferee is an insurance  company,  the source of funds used to
purchase the Class M or 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)) and
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  or (ii) in the  case of any  such  Class M or  Class B  Certificate
presented for registration in the name of a Plan, or a trustee of any such Plan,
(A) an Opinion  of Counsel  satisfactory  to the  Trustee  and the Seller to the
effect that the purchase or holding of such Class M or Class B Certificate  will
not result in the assets of the Trust Estate  being  deemed to be "plan  assets"
and  subject to the  prohibited  transaction  provisions  of ERISA,  the Code or
Similar Law and will not subject the Trustee,  the Seller or the Master Servicer
to any  obligation  in addition to those  undertaken  in this  Agreement,  which
Opinion of Counsel  shall not be an  expense of the  Trustee,  the Seller or the
Master Servicer and (B) such other opinions of counsel,  officer's  certificates
and  agreements  as the Seller or the Master  Servicer may require in connection
with such  transfer,  which  opinions of  counsel,  officers'  certificates  and
agreements  shall not be an  expense  of the  Trustee,  the Seller or the Master
Servicer.  The Class M and Class B Certificates shall bear a legend referring to
the foregoing restrictions contained in this paragraph.

          (d) No legal or beneficial interest in all or any portion of the Class
A-R  Certificate  may be transferred  directly or indirectly to a  "disqualified
organization"  within the meaning of Code  Section  860E(e)(5)  or an agent of a
disqualified organization (including a broker, nominee, or middleman), to a Plan
or a Person  investing  the assets of a Plan  (such  plan or  Person,  an "ERISA
Prohibited  Holder")  or to an  individual,  corporation,  partnership  or other
person unless such transferee (i) is not a Non-U.S. Person or (ii) is a Non-U.S.
Person that holds the Class A-R  Certificate in connection with the conduct of a
trade or business  within the United States and has furnished the transferor and
the Trustee with an effective  Internal  Revenue Service Form 4224 or (iii) is a
Non-U.S.  Person that has  delivered to both the  transferor  and the Trustee an
opinion of a nationally  recognized  tax counsel to the effect that the transfer
of the Class A-R Certificate to it is in accordance with the requirements of the
Code and the  regulations  promulgated  thereunder and that such transfer of the
Class A-R  Certificate  will not be disregarded  for federal income tax purposes
(any such  person who is not covered by clauses  (i),  (ii) or (iii) above being
referred to herein as a "Non-permitted  Foreign Holder"), and any such purported
transfer  shall be void and have no effect.  The Trustee shall not execute,  and
shall not authenticate (or cause the  Authenticating  Agent to authenticate) and
deliver,  a new Class A-R  Certificate in connection with any such transfer to a
disqualified  organization  or agent  thereof  (including  a broker,  nominee or
middleman),  an ERISA Prohibited Holder or a Non-permitted  Foreign Holder,  and
neither the  Certificate  Registrar nor the Trustee shall accept a surrender for
transfer or registration of transfer, or register the transfer of, the Class A-R
Certificate,  unless  the  transferor  shall  have  provided  to the  Trustee an
affidavit, substantially in the form attached as Exhibit H hereto, signed by the
transferee,  to the  effect  that  the  transferee  is not  such a  disqualified
organization,  an agent  (including a broker,  nominee,  or  middleman)  for any
entity as to which the  transferee  has not  received  a  substantially  similar
affidavit,  an ERISA Prohibited Holder or a Non-permitted  Foreign Holder, which
affidavit  shall contain the consent of the transferee to any such amendments of
this  Agreement  as  may  be  required  to  further   effectuate  the  foregoing
restrictions   on  transfer  of  the  Class  A-R   Certificate  to  disqualified
organizations,  ERISA Prohibited Holders or Non-permitted  Foreign Holders. Such
affidavit  shall also  contain  the  statement  of the  transferee  that (i) the
transferee has historically  paid its debts as they have come due and intends to
do so in  the  future,  (ii)  the  transferee  understands  that  it  may  incur
liabilities in excess of cash flows  generated by the residual  interest,  (iii)
the  transferee  intends  to pay taxes  associated  with  holding  the  residual
interest as they become due and (iv) the transferee  will not transfer the Class
A-R Certificate to any Person who does not provide an affidavit substantially in
the form attached as Exhibit H hereto.

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

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

     Section 5.03. Mutilated, Destroyed, Lost or Stolen Certificates.

     If (i) any  mutilated  Certificate  is  surrendered  to the  Trustee or the
Authenticating  Agent,  or the  Trustee  or the  Authenticating  Agent  receives
evidence  to  its  satisfaction  of  the  destruction,  loss  or  theft  of  any
Certificate,  and (ii) there is delivered  to the Trustee or the  Authenticating
Agent such security or indemnity as may be required by them to hold each of them
harmless,  then,  in the absence of notice to the Trustee or the  Authenticating
Agent that such  Certificate  has been  acquired by a bona fide  purchaser,  the
Trustee shall execute and  authenticate  (or cause the  Authenticating  Agent to
authenticate)  and deliver,  in exchange  for or in lieu of any such  mutilated,
destroyed,  lost or stolen  Certificate,  a new  Certificate  of like  tenor and
principal portion or Percentage Interest and of the same Class or Subclass. Upon
the  issuance  of any new  Certificate  under this  Section,  the Trustee or the
Certificate  Registrar may require the payment of a sum  sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other  expense   (including  the  fees  and  expenses  of  the  Trustee  or  the
Authenticating Agent) in connection therewith.  Any duplicate Certificate issued
pursuant to this Section shall constitute complete and indefeasible  evidence of
ownership in the Trust Estate, as if originally issued, whether or not the lost,
stolen, or destroyed Certificate shall be found at any time.

     Section 5.04. Persons Deemed Owners.

     Prior  to  the  due  presentation  of a  Certificate  for  registration  of
transfer,  the  Seller,  the  Master  Servicer,  the  Trustee,  the  Certificate
Registrar and any agent of the Seller,  the Master Servicer,  the Trustee or the
Certificate  Registrar  may treat the  Person in whose name any  Certificate  is
registered  as the  owner  of such  Certificate  for the  purpose  of  receiving
distributions  pursuant to Section 4.01, and for all other purposes  whatsoever,
and  neither the Seller,  the Master  Servicer,  the  Trustee,  the  Certificate
Registrar nor any agent of the Seller,  the Master Servicer,  the Trustee or the
Certificate Registrar shall be affected by notice to the contrary.

     Section 5.05. Access to List of Certificateholders' Names and Addresses.

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

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

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

     Section 5.06. Maintenance of Office or Agency.

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

     Section 5.07. Definitive Certificates.

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

     Section 5.08. Notices to Clearing Agency.

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

                                  ARTICLE VI

                      THE SELLER AND THE MASTER SERVICER

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

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

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

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

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

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

     Neither the Seller nor the Master Servicer nor any subcontractor nor any of
the partners,  directors,  officers, employees or agents of any of them shall be
under any liability to the Trust Estate or the  Certificateholders  and all such
Persons shall be held harmless for any action taken or for  refraining  from the
taking of any action in good faith pursuant to this Agreement,  or for errors in
judgment;  provided,  however,  that this  provision  shall not protect any such
Person  against  any breach of  warranties  or  representations  made  herein or
against  any  liability  which would  otherwise  be imposed by reason of willful
misfeasance,  bad faith or gross  negligence in the  performance of duties or by
reason of reckless  disregard of obligations and duties  hereunder.  The Seller,
the Master Servicer,  any  subcontractor,  and any partner,  director,  officer,
employee  or agent of any of them shall be entitled  to  indemnification  by the
Trust Estate and will be held  harmless  against any loss,  liability or expense
incurred in connection  with any legal action  relating to this Agreement or the
Certificates,  other than any loss,  liability or expense  incurred by reason of
willful misfeasance,  bad faith or gross negligence in the performance of his or
its  duties  hereunder  or by  reason  of  reckless  disregard  of  his  or  its
obligations and duties hereunder. The Seller, the Master Servicer and any of the
directors, officers, employees or agents of either may rely in good faith on any
document of any kind which,  prima facie, is properly  executed and submitted by
any Person respecting any matters arising hereunder.  Neither the Seller nor the
Master Servicer shall be under any obligation to appear in,  prosecute or defend
any legal action  unless such action is related to its  respective  duties under
this  Agreement  and which in its opinion  does not involve it in any expense or
liability;  provided, however, that the Seller or the Master Servicer may in its
discretion  undertake  any such action which it may deem  necessary or desirable
with respect to this  Agreement and the rights and duties of the parties  hereto
and the interests of the Certificateholders  hereunder if the Certificateholders
offer to the  Seller  or the  Master  Servicer,  as the case may be,  reasonable
security or indemnity  against the costs,  expenses and liabilities which may be
incurred therein or thereby. In such event, the legal expenses and costs of such
action  and any  liability  resulting  therefrom  shall be  expenses,  costs and
liabilities of the Trust Estate,  and the Seller or the Master Servicer shall be
entitled to be  reimbursed  therefor out of the  Certificate  Account,  and such
amounts shall,  on the following  Distribution  Date or  Distribution  Dates, be
allocated  in  reduction  of  distributions  on the Class A, Class M and Class B
Certificates  in the same manner as Realized  Losses are  allocated  pursuant to
Section 4.02(a).

     Section 6.04. Resignation of the Master Servicer.

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

     Section 6.05. Compensation to the Master Servicer.

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

     Section 6.06. Assignment or Delegation of Duties by Master Servicer.

     The  Master  Servicer  shall not  assign  or  transfer  any of its  rights,
benefits or privileges under this Agreement to any other Person,  or delegate to
or subcontract  with, or authorize or appoint any other Person to perform any of
the duties,  covenants or  obligations  to be  performed by the Master  Servicer
without the prior written consent of the Trustee, and any agreement,  instrument
or act  purporting  to  effect  any such  assignment,  transfer,  delegation  or
appointment shall be void.  Notwithstanding  the foregoing,  the Master Servicer
shall have the right  without  the prior  written  consent of the Trustee (i) to
assign its rights and delegate its duties and obligations  hereunder;  provided,
however,  that (a) the  purchaser or  transferee  accepting  such  assignment or
delegation  is  qualified  to  service  mortgage  loans  for FNMA or  FHLMC,  is
satisfactory  to the Trustee,  in the exercise of its reasonable  judgment,  and
executes  and  delivers  to the  Trustee  an  agreement,  in form and  substance
reasonably  satisfactory  to the Trustee,  which  contains an assumption by such
purchaser or transferee of the due and punctual  performance  and  observance of
each covenant and  condition to be performed or observed by the Master  Servicer
hereunder  from and after the date of such  agreement;  and (b) each  applicable
Rating Agency's rating of any Certificates in effect  immediately  prior to such
assignment,  sale  or  transfer  is  not  reasonably  likely  to  be  qualified,
downgraded or withdrawn as a result of such assignment, sale or transfer and the
Certificates  are not reasonably  likely to be placed on credit review status by
any such Rating Agency; and (ii) to delegate to, subcontract with, authorize, or
appoint an affiliate of the Master Servicer to perform and carry out any duties,
covenants or obligations to be performed and carried out by the Master  Servicer
under this Agreement and hereby agrees so to delegate, subcontract, authorize or
appoint  to an  affiliate  of the  Master  Servicer  any  duties,  covenants  or
obligations to be performed and carried out by the Master Servicer to the extent
that such duties,  covenants or obligations  are to be performed in any state or
states in which the  Master  Servicer  is not  authorized  to do  business  as a
foreign  corporation  but in which the affiliate is so  authorized.  In no case,
however,  shall any  permitted  assignment  and  delegation  relieve  the Master
Servicer of any  liability  to the Trustee or the Seller  under this  Agreement,
incurred  by it prior to the time that the  conditions  contained  in clause (i)
above are met.

     Section 6.07. Indemnification of Trustee and Seller by Master Servicer.

     The Master  Servicer shall  indemnify and hold harmless the Trustee and the
Seller and any director, officer or agent thereof against any loss, liability or
expense,  including  reasonable  attorney's fees,  arising out of, in connection
with or incurred by reason of willful  misfeasance,  bad faith or  negligence in
the  performance  of duties of the Master  Servicer  under this  Agreement or by
reason of reckless disregard of its obligations and duties under this Agreement.
Any payment  pursuant to this Section made by the Master Servicer to the Trustee
or the  Seller  shall be from such  entity's  own funds,  without  reimbursement
therefor.  The provisions of this Section 6.03 shall survive the  termination 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 FHMLC,  which  ineligibility
continues unremedied for a period of 90 days.

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

     Section 7.02. Other Remedies of Trustee.

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

     Section 7.03. Directions by Certificateholders and Duties of Trustee During
Event of Default.

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

     Section 7.04.  Action upon Certain Failures of the Master Servicer and upon
Event of Default.

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

     Section 7.05. Trustee to Act; Appointment of Successor.

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

     Section 7.06. Notification to Certificateholders.

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

                                 ARTICLE VIII

                            CONCERNING THE TRUSTEE

     Section 8.01. Duties of Trustee.

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

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

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

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

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

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

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

     Section 8.02. Certain Matters Affecting the Trustee.

     Except as otherwise provided in Section 8.01:

               (i) The  Trustee  may 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;

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

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

     Section 8.03. Trustee Not Required to Make Investigation.

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

     Section 8.04. Trustee Not Liable for Certificates or Mortgage Loans.

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

     Section 8.05. Trustee May Own Certificates.

     The Trustee and any agent thereof, in its individual or any other capacity,
may become the owner or pledgee of  Certificates  with the same  rights it would
have if it were not Trustee or such agent.

     Section 8.06. The Master Servicer to Pay Fees and Expenses.

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

     Section 8.07. Eligibility Requirements.

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

     Section 8.08. Resignation and Removal.

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

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

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

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

     Section 8.09. Successor.

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

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

     Section 8.10. Merger or Consolidation.

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

     Section 8.11. Authenticating Agent.

     The Trustee may appoint an Authenticating  Agent, which shall be authorized
to act on  behalf  of  the  Trustee  in  authenticating  Certificates.  Wherever
reference is made in this Agreement to the authentication of Certificates by the
Trustee or the Trustee's  countersignature,  such  reference  shall be deemed to
include  authentication on behalf of the Trustee by the Authenticating Agent and
a  certificate  of  authentication  executed  on  behalf of the  Trustee  by the
Authenticating  Agent. The Authenticating Agent must be acceptable to the Seller
and the Master  Servicer and must be a corporation  organized and doing business
under  the laws of the  United  States  of  America  or of any  state,  having a
principal  office and place of  business in a state and city  acceptable  to the
Seller and the Master  Servicer,  having a combined  capital  and  surplus of at
least $15,000,000, authorized under such laws to do a trust business and subject
to supervision or examination by federal or state authorities.

     Any  corporation  into  which  the  Authenticating  Agent  may be merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which the Authenticating  Agent
shall be a party, or any corporation succeeding to the corporate agency business
of the  Authenticating  Agent,  shall be the  Authenticating  Agent  without the
execution  or filing of any paper or any  further act on the part of the Trustee
or the Authenticating Agent.

     The Authenticating Agent may at any time resign by giving at least 30 days'
advance written notice of resignation to the Trustee,  the Seller and the Master
Servicer. The Trustee may at any time terminate the agency of the Authenticating
Agent by giving written notice thereof to the  Authenticating  Agent, the Seller
and the Master  Servicer.  Upon receiving a notice of resignation or upon such a
termination,  or in case at any time the Authenticating  Agent shall cease to be
eligible in accordance  with the  provisions  of this Section 8.11,  the Trustee
promptly  shall  appoint  a  successor  Authenticating  Agent,  which  shall  be
acceptable  to the  Master  Servicer,  and  shall  give  written  notice of such
appointment  to the  Seller,  and shall mail notice of such  appointment  to all
Certificateholders.  Any successor  Authenticating  Agent upon acceptance of its
appointment  hereunder shall become vested with all the rights,  powers,  duties
and  responsibilities  of its  predecessor  hereunder,  with  like  effect as if
originally named as  Authenticating  Agent herein.  No successor  Authenticating
Agent shall be appointed  unless  eligible  under the provisions of this Section
8.11.

     The Authenticating  Agent shall have no responsibility or liability for any
action  taken by it as such at the  direction  of the  Trustee.  Any  reasonable
compensation paid to the  Authenticating  Agent shall be a reimbursable  expense
under Section 8.06.

     Section 8.12. Separate Trustees and Co-Trustees.

     The  Trustee  shall have the power from time to time to appoint one or more
persons or corporations  to act either as co-trustees  jointly with the Trustee,
or as separate  trustees,  for the purpose of holding title to,  foreclosing  or
otherwise  taking  action with  respect to any  Mortgage  Loan outside the state
where the Trustee  has its  principal  place of  business,  where such  separate
trustee or  co-trustee  is necessary or advisable  (or the Trustee is advised by
the Master  Servicer  that such  separate  trustee or co-trustee is necessary or
advisable) under the laws of any state in which a Mortgaged  Property is located
or for the purpose of otherwise conforming to any legal requirement, restriction
or  condition  in any state in which a  Mortgaged  Property is located or in any
state in which any portion of the Trust Estate is located.  The Master  Servicer
shall advise the Trustee when, in its good faith opinion,  a separate trustee or
co-trustee  is necessary or advisable  as  aforesaid.  The separate  trustees or
co-trustees  so  appointed  shall  be  trustees  for the  benefit  of all of the
Certificateholders  and shall have such powers,  rights and remedies as shall be
specified in the  instrument of  appointment;  provided,  however,  that no such
appointment  shall, or shall be deemed to,  constitute the appointee an agent of
the  Trustee.  The  Seller  and the  Master  Servicer  shall  join  in any  such
appointment,  but such joining shall not be necessary for the  effectiveness  of
such appointment.

     Every separate  trustee and co-trustee  shall,  to the extent  permitted by
law, be appointed and act subject to the following provisions and conditions:

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

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

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

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

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

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

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

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

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

     Section 8.13. Appointment of Custodians.

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

     Section 8.14. Tax Matters; Compliance with REMIC Provisions.

          (a) Each of the Trustee and the Master  Servicer  covenants and agrees
that it shall perform its duties hereunder in a manner consistent with the REMIC
Provisions  and shall not  knowingly  take any action or fail to take any action
that would (i) affect the determination of the Trust Estate's status as a REMIC;
or (ii) cause the imposition of any federal,  state or local income,  prohibited
transaction,  contribution or other tax on either the REMIC or the Trust Estate.
The  Master  Servicer,  or,  in the  case of any  action  required  by law to be
performed directly by the Trustee, the Trustee, shall (i) prepare or cause to be
prepared, timely cause to be signed by the Trustee and file or cause to be filed
annual  federal  and  applicable  state and local  income  tax  returns  using a
calendar  year as the  taxable  year for the  REMIC  and the  accrual  method of
accounting;  (ii) in the first such  federal  tax return,  make,  or cause to be
made, elections  satisfying the requirements of the REMIC Provisions,  on behalf
of the  Trust  Estate,  to treat the Trust  Estate  as a REMIC;  (iii)  prepare,
execute and forward,  or cause to be prepared,  executed and  forwarded,  to the
Certificateholders  all information reports or tax returns required with respect
to the REMIC, as and when required to be provided to the Certificateholders, and
to the  Internal  Revenue  Service and any other  relevant  governmental  taxing
authority  in  accordance  with the REMIC  Provisions  and any other  applicable
federal,  state or local laws, including without limitation  information reports
relating to "original  issue  discount" and "market  discount" as defined in the
Code based upon the issue prices,  prepayment assumption and cash flows provided
by the Seller to the  Trustee  and  calculated  on a monthly  basis by using the
issue prices of the Certificates;  (iv) make available information necessary for
the  application  of any tax imposed on  transferors  of residual  interests  to
"disqualified  organizations"  (as  defined in the REMIC  Provisions);  (v) file
Forms SS-4 and 8811 and  respond to  inquiries  by  Certificateholders  or their
nominees concerning  information returns,  reports or tax returns; (vi) maintain
(or cause to be maintained by the Servicer) such records  relating to the REMIC,
including but not limited to the income,  expenses,  individual  Mortgage  Loans
(including REO Mortgage Loans,  other assets and  liabilities of the REMIC,  and
the fair market value and adjusted  basis of the REMIC  property  determined  at
such  intervals  as may be required by the Code,  as may be necessary to prepare
the foregoing returns or information reports; (vii) exercise reasonable care not
to allow the creation of any "interests" in the REMIC within the meaning of Code
Section 860D(a)(2) other than the interests  represented by the Class A-1, Class
A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-PO and Class
A-R  Certificates,  the Class M Certificates and the Class B-l, Class B-2, Class
B-3, Class B-4 and Class B-5 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 tax matters person
in accordance with the REMIC Provisions).  The Master Servicer shall be entitled
to be  reimbursed  pursuant to Section 3.02 for any taxes paid by it pursuant to
clause (x) of the preceding  sentence,  except to the extent that such taxes are
imposed as a result of the bad faith, willful misfeasance or gross negligence of
the Master Servicer in the performance of its obligations hereunder. The Trustee
shall sign the tax  returns  referred  to in clause (i) of the second  preceding
sentence.

     In order to enable the Master Servicer or the Trustee,  as the case may be,
to perform its duties as set forth above, the Seller shall provide,  or cause to
be provided,  to the Master  Servicer within ten days after the Closing Date all
information or data that the Master  Servicer  determines to be relevant for tax
purposes to the valuations and offering prices of the  Certificates,  including,
without limitation,  the price, yield,  prepayment assumption and projected cash
flows of each Class and Subclass of  Certificates  and the Mortgage Loans in the
aggregate.  Thereafter,  the Seller shall provide to the Master  Servicer or the
Trustee, as the case may be, promptly upon request therefor, any such additional
information or data that the Master Servicer or the Trustee, as the case may be,
may from time to time, request in order to enable the Master Servicer to perform
its duties as set forth above. The Seller hereby indemnifies the Master Servicer
and the Trustee for any losses, liabilities,  damages, claims or expenses of the
Master Servicer or the Trustee arising from any errors or miscalculations by the
Master  Servicer or the Trustee  pursuant to this  Section  that result from any
failure  of  the  Seller  to  provide,  or to  cause  to be  provided,  accurate
information or data to the Master  Servicer or the Trustee,  as the case may be,
on a timely basis.  The Master  Servicer  hereby  indemnifies the Seller and the
Trustee for any losses,  liabilities,  damages, claims or expenses of the Seller
or the Trustee arising from the Master Servicer's willful misfeasance, bad faith
or gross negligence in preparing any of the federal, state and local tax returns
of the REMIC as described  above. In the event that the Trustee  prepares any of
the federal,  state and local tax returns of the REMIC as described  above,  the
Trustee hereby  indemnifies  the Seller and the Master  Servicer for any losses,
liabilities,  damages,  claims or expenses of the Seller or the Master  Servicer
arising from the  Trustee's  willful  misfeasance,  bad faith or  negligence  in
connection with such preparation.

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

     Section 8.15. Monthly Advances.

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

                                   ARTICLE IX

                                   TERMINATION

     Section 9.01. Termination upon Purchase by the Seller or Liquidation of All
Mortgage Loans.

     Subject to Section 9.02, the respective obligations and responsibilities of
the Seller,  the Master  Servicer and the Trustee created hereby (other than the
obligation of the Trustee to make certain payments after the Final  Distribution
Date to  Certificateholders  and the  obligation of the Master  Servicer to send
certain notices as hereinafter set forth and the tax reporting obligations under
Sections 4.05 and 8.14 hereof) shall  terminate upon the last action required to
be taken by the Trustee on the Final  Distribution Date pursuant to this Article
IX following the earlier of (i) the purchase by the Seller of all Mortgage Loans
and all property acquired in respect of any Mortgage Loan remaining in the Trust
Estate at a price equal to the sum of (x) 100% of the unpaid  principal  balance
of each  Mortgage  Loan  (other  than any REO  Mortgage  Loan)  as of the  Final
Distribution  Date,  and (y) the fair  market  value of the  Mortgaged  Property
related to any REO Mortgage Loan (as determined by the Master Servicer as of the
close of business on the third  Business Day next  preceding the date upon which
notice of any such  termination is furnished to  Certificateholders  pursuant to
the third paragraph of this Section 9.01),  plus any accrued and unpaid interest
through the last day of the month  preceding  the month of such  purchase at the
applicable Mortgage Interest Rate less any Fixed Retained Yield on each Mortgage
Loan  (including  any REO  Mortgage  Loan) and (ii) the final  payment  or other
liquidation  (or any advance with  respect  thereto) of the last  Mortgage  Loan
remaining in the Trust Estate  (including  for this purpose the discharge of any
Mortgagor under a defaulted Mortgage Loan on which the 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 11.23. In the case of any purchase by the Seller pursuant to said clause
(i),  the Seller  shall  provide to the  Trustee the  certification  required by
Section 3.04 and the Trustee and the Custodian shall, promptly following payment
of the  purchase  price,  release to the Seller  the Owner  Mortgage  Loan Files
pertaining to the Mortgage Loans being purchased.

     Notice of any termination,  specifying the Final  Distribution  Date (which
shall be a date that  would  otherwise  be a  Distribution  Date) upon which the
Certificateholders  may surrender their  Certificates to the Trustee for payment
of the final  distribution  and  cancellation,  shall be given  promptly  by the
Master  Servicer  (if it is  exercising  its right to purchase the assets of the
Trust   Estate)  or  by  the   Trustee   (in  any  other   case)  by  letter  to
Certificateholders  mailed not earlier than the 15th day of the month  preceding
the month of such final distribution and not later than the twentieth day of the
month of such final distribution specifying (A) the Final Distribution Date upon
which  final  payment of the  Certificates  will be made upon  presentation  and
surrender  of  Certificates  at the  office  or agency  of the  Trustee  therein
designated,  (B) the  amount of any such final  payment  and (C) that the Record
Date otherwise applicable to such Distribution Date is not applicable,  payments
being made (except in the case of any Class A Certificate surrendered on a prior
Distribution Date pursuant to Section 4.01) only upon presentation and surrender
of the Certificates at the office or agency of the Trustee therein specified. If
the  Master  Servicer  is  obligated  to give  notice to  Certificateholders  as
aforesaid,  it  shall  give  such  notice  to the  Trustee  and the  Certificate
Registrar at the time such notice is given to  Certificateholders.  In the event
such notice is given by the Master  Servicer,  the Master Servicer shall deposit
in  the  Certificate  Account  on or  before  the  Final  Distribution  Date  in
immediately available funds an amount equal to the purchase price for the assets
of the Trust  Estate  computed  as above  provided.  Failure  to give  notice of
termination  as described  herein shall not entitle a  Certificateholder  to any
interest beyond the interest payable on the Final Distribution Date.

     Upon  presentation  and  surrender of the  Certificates,  the Trustee shall
cause to be distributed to  Certificateholders on the Final Distribution Date in
proportion to their respective Percentage Interests an amount equal to (i) as to
the  Subclasses  of  Class A  Certificates,  the  respective  Class  A  Subclass
Principal  Balance  together with any related Class A Subclass  Unpaid  Interest
Shortfall and one month's  interest in an amount equal to the respective Class A
Subclass Interest Accrual Amount, (ii) as to the Class M Certificates, the Class
M Principal Balance together with any related Class M Unpaid Interest  Shortfall
and one  month's  interest  at the  Class  M  Pass-Through  Rate on the  Class M
Principal  Balance,  (iii) as to the  Subclasses  of Class B  Certificates,  the
respective Class B Subclass  Principal Balance together with any related Class B
Subclass Unpaid Interest  Shortfall and one month's  interest in an amount equal
to the respective  Class B Subclass  Interest  Accrual Amount and (iv) 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
Servicer and the Trustee of any Periodic  Advances,  is  insufficient  to pay in
full the amounts  set forth in clauses  (i),  (ii) and (iii) of this  paragraph,
then   any   shortfall   in   the   amount   available   for   distribution   to
Certificateholders  shall be allocated  in  reduction  of the amounts  otherwise
distributable  on the Final  Distribution  Date in the same  manner as  Realized
Losses are  allocated  pursuant to Sections  4.02(b)  and 4.02(g)  hereof.  Such
distribution on the Final Distribution Date shall be in lieu of the distribution
otherwise required to be made on such Distribution Date in respect of each Class
of Certificates.

     In the event that all of the  Certificateholders  shall not surrender their
Certificates  for final payment and  cancellation  within three months following
the Final  Distribution Date, the Trustee shall on such date cause all funds, if
any,  in the  Certificate  Account  not  distributed  in final  distribution  to
Certificateholders  to be  withdrawn  therefrom  and  credited to the  remaining
Certificateholders by depositing such funds in a separate escrow account for the
benefit of such Certificateholders, and the Master Servicer (if it exercised its
right to purchase  the assets of the Trust  Estate) or the Trustee (in any other
case) shall give a second written notice to the remaining  Certificateholders to
surrender their Certificates for cancellation and receive the final distribution
with respect  thereto.  If within  three months after the second  notice all the
Certificates  shall not have been surrendered for cancellation,  the Trustee may
take appropriate  steps, or may appoint an agent to take  appropriate  steps, to
contact  the  remaining   Certificateholders   concerning   surrender  of  their
Certificates,  and the cost thereof shall be paid out of the funds on deposit in
such escrow account.

     Section 9.02. Additional Termination Requirements.

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

               (i) The notice given by the Master  Servicer  under  Section 9.01
shall  provide that such notice  constitutes  the adoption of a plan of complete
liquidation of the REMIC as of the date of such notice (or, if earlier, the date
on which the first  such  notice is mailed to  Certificateholders).  The  Master
Servicer  shall also specify such date in a statement  attached to the final tax
return of the REMIC; and

               (ii) At or after the time of  adoption of such a plan of complete
liquidation  and at or prior to the Final  Distribution  Date, the Trustee shall
sell  all of the  assets  of the  Trust  Estate  to the  Seller  for cash at the
purchase price  specified in Section 9.01 and shall  distribute such cash within
90 days of such adoption in the manner specified in Section 9.01.

                           MISCELLANEOUS PROVISIONS

     Section 10.01. Amendment.

          (a) This Agreement or any Custodial Agreement may be amended from time
to time by the Seller, the Master Servicer and the Trustee,  without the consent
of any of the Certificateholders,  (i) to cure any ambiguity or mistake, (ii) to
correct or supplement any provisions herein or therein which may be inconsistent
with any other provisions herein or therein,  (iii) to modify,  eliminate or add
to any of its  provisions  to such extent as shall be  necessary to maintain the
qualification  of the Trust Estate as a REMIC at all times that any Certificates
are  outstanding  or to avoid or  minimize  the  risk of the  imposition  of any
federal tax on the Trust Estate or the REMIC  pursuant to the Code that would be
a claim against the Trust Estate,  provided that (a) the Trustee has received an
Opinion of Counsel to the effect that such action is  necessary  or desirable to
maintain such  qualification  or to avoid or minimize the risk of the imposition
of any such tax and (b) such action  shall not, as  evidenced by such Opinion of
Counsel,  adversely  affect  in  any  material  respect  the  interests  of  any
Certificateholder,  (iv) to change the timing and/or nature of deposits into the
Certificate  Account provided that (a) such change shall not, as evidenced by an
Opinion of Counsel,  adversely  affect in any material  respect the interests of
any  Certificateholder  and (b) such  change  shall  not  adversely  affect  the
then-current  rating of the  Certificates  as  evidenced  by a letter  from each
Rating Agency to such effect, (v) to modify,  eliminate or add to the provisions
of Section  5.02 or any other  provisions  hereof  restricting  transfer  of the
Certificates, provided that the Master Servicer for purposes of Section 5.02 has
determined in its sole discretion that any such  modifications to this Agreement
will neither  adversely affect the rating on the Certificates nor give rise to a
risk that either the Trust Estate or the REMIC or any of the  Certificateholders
will be subject to a tax caused by a transfer to a non-permitted  transferee and
(vi) to make any other  provisions with respect to matters or questions  arising
under this Agreement or such Custodial  Agreement  which shall not be materially
inconsistent  with the provisions of this  Agreement,  provided that such action
shall  not,  as  evidenced  by an Opinion of  Counsel,  adversely  affect in any
material respect the interests of any Certificateholder.

     This Agreement or any Custodial  Agreement may also be amended from time to
time by the Seller,  the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing in the aggregate not less than 66-2/3% of the
aggregate  Voting  Interests of each Class or Subclass 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 or Subclass; 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 or Subclass in
a manner  other than as  described  in clause (i) hereof  without the consent of
Holders of Certificates of such Class or Subclass  evidencing,  as to such Class
or Subclass,  Voting Interests aggregating not less than 66-2/3% or (iii) reduce
the aforesaid percentage of Certificates of any Class or Subclass the Holders of
which are required to consent to any such amendment,  without the consent of the
Holders of all Certificates of such Class or Subclass then outstanding.

     Notwithstanding any contrary provision of this Agreement, the Trustee shall
not  consent  to any  amendment  to this  Agreement  unless it shall  have first
received  an  Opinion of Counsel  to the  effect  that such  amendment  will not
subject the REMIC to tax or cause the Trust Estate to fail to qualify as a REMIC
at any time that any Certificates are outstanding.

     Promptly  after the  execution of any  amendment  requiring  the consent of
Certificateholders,  the  Trustee  shall  furnish  written  notification  of the
substance of such amendment to each Certificateholder.

     It shall not be necessary for the consent of Certificateholders  under this
Section 10.01(a) to approve the particular form of any proposed  amendment,  but
it shall be sufficient if such consent shall approve the substance thereof.  The
manner of obtaining  such consents and of evidencing  the  authorization  of the
execution  thereof by  Certificateholders  shall be  subject to such  reasonable
regulations as the Trustee may prescribe.

          (b)  Notwithstanding  any contrary  provision of this  Agreement,  the
Master  Servicer may,  from time to time,  amend  Schedule I hereto  without the
consent of any  Certificateholder  or the Trustee;  provided,  however, (i) that
such amendment does not conflict with any provisions of the Servicing Agreement,
(ii) that the Servicing  Agreement  provides for the  remittance of each type of
Unscheduled  Principal  Receipts  received by the 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:

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

          (b) changing the Applicable  Unscheduled  Principal Receipt Period for
all Mortgage Loans  serviced by the Servicer to a Mid-Month  Receipt Period with
respect to Full  Unscheduled  Principal  Receipts  and to a Prior Month  Receipt
Period with respect to Partial Unscheduled Principal Receipts.

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

     Section 10.02. Recordation of Agreement.

     This  Agreement (or an abstract  hereof,  if  acceptable to the  applicable
recording  office) is subject to recordation in all  appropriate  public offices
for real property records in all the towns or other comparable  jurisdictions in
which any or all of the  Mortgaged  Properties  are  situated,  and in any other
appropriate  public office or elsewhere,  such recordation to be effected by the
Master  Servicer and at its expense on  direction by the Trustee,  but only upon
direction  accompanied  by an  Opinion  of  Counsel  to  the  effect  that  such
recordation   materially   and   beneficially   affects  the  interests  of  the
Certificateholders.

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

     Section 10.03. Limitation on Rights of Certificateholders.

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

     Except as otherwise expressly provided herein, no Certificateholder, solely
by virtue of its status as a Certificateholder,  shall have any right to vote or

Certificates and the Class B-2 Certificates) used to price this Certificate: (i)

Certificate is approximately 14.21979167%;  (ii) the annual yield to maturity of
this  Certificate,  compounded  monthly,  is approximately  9.57%; and (iii) the
amount of OID allocable to the short first accrual period  (February 26, 1997 to

     THIS CERTIFIES THAT  -----------------------------  is the registered owner

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 26, 1997 (the
"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master servicer (the "Master Servicer"),  and First Union National Bank of North
Carolina,  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,  Class M Certificates  and each Subclass of
Class B Certificates  bearing a lower numerical  designation as specified in the
Agreement,  any Class B-5  Distribution  Amount  required to be  distributed  to
Holders  of  Class  B-5  Certificates  on such  Distribution  Date,  subject  to
adjustment,  in certain events, as specified in the Agreement.  The pass-through
rate on the Class B-5 Certificates  applicable to each Distribution Date will be
7.25 per annum.  The amount of interest which accrues on this Certificate in any
month will be subject to reduction  with respect to any  Non-Supported  Interest
Shortfall and the interest  portion of certain  Realized Losses allocated to the
Class B-5 Certificates, as described in the Agreement.

     Distributions  on this  Certificate  will be made on behalf of the  Trustee
either by the  Master  Servicer  or by a Paying  Agent  appointed  by the Master
Servicer by check mailed to the address of the Person entitled thereto,  as such
name and address shall appear on the Certificate  Register.  Notwithstanding the
above,  the final  distribution  in reduction of the  principal  balance of this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  specified  by the  Trustee  for  that  purpose  in the  notice  of final
distribution.

     No transfer of a Class B-5 Certificate will be made unless such transfer is
exempt from the  registration  requirements  of the  Securities  Act of 1933, as
amended,  and any applicable state securities laws or is made in accordance with
said Act and laws.  In the event that such a  transfer  is desired to be made by
the Holder hereof,  (i) the transferee will be required to execute an investment
letter in the form described in the Agreement and (ii) if such transfer is to be
made within  three  years from the later of (a) the date of initial  issuance of
the  Certificates  or (b) the last  date on which the  Seller  or any  affiliate
thereof was a Holder of the Certificates proposed to be transferred,  and unless
such transfer is made in reliance on Rule 144A of the Securities Act of 1933, as
amended,  the Trustee or the Seller may require the Holder to deliver an opinion
of counsel  acceptable to and in form and substance  satisfactory to the Trustee
and the Seller that such transfer is exempt (describing the applicable exemption
and the basis  therefor)  from or is being  made  pursuant  to the  registration
requirements  of the Securities  Act of 1933, as amended,  and of any applicable
statute of any state.  The Holder hereof desiring to effect such transfer shall,
and does  hereby  agree to,  indemnify  the  Trustee,  the  Seller,  the  Master
Servicer,  and any Paying  Agent  acting on behalf of the  Trustee  against  any
liability  that may  result if the  transfer  is not so exempt or is not made in
accordance  with  such  Federal  and state  laws.  In  connection  with any such
transfer,  the Holder  must also  deliver to the  Trustee  (i) a  representation
letter,  in the form as described in the Agreement,  stating either (a) that the
transferee  is not a Plan and is not  acting  on  behalf  of a Plan or using the
assets of a Plan to effect such  purchase  or (b) subject to certain  conditions
described  in the  Agreement,  that the  source of funds used to  purchase  this
Certificate  is  an  "insurance  company  general  account,"  or  (ii)  if  such
transferee  is a Plan,  (a) an opinion of counsel  acceptable to and in form and
substance  satisfactory  to the Trustee  and the Seller with  respect to certain
matters and (b) such other  documentation  as the Seller or the Master  Servicer
may require, as described in the Agreement.

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

     This  Certificate  is issued on February 26,  1997,  and based on its issue
price of 37.50347%, including accrued interest, and a stated redemption price at
maturity equal to its initial principal balance (plus one day of interest at the
Pass-Through  Rate hereon),  is issued with original issue discount  ("OID") for
federal income tax purposes.  Assuming that this  Certificate pays in accordance
with projected cash flows  reflecting the Prepayment  Assumption of 350% SPA (as
defined in the Prospectus Supplement dated February 20, 1997 with respect to the
offering of the Class A Certificates,  the Class M  Certificates,  the Class B-1
Certificates and the Class B-2 Certificates) used to price this Certificate: (i)
the  amount of OID as a  percentage  of the  initial  principal  balance of this
Certificate is approximately 62.51666667%;  (ii) the annual yield to maturity of
this Certificate,  compounded  monthly,  is approximately  25.44%; and (iii) the
amount of OID allocable to the short first accrual period  (February 26, 1997 to
March  25,  1997) as a  percentage  of the  initial  principal  balance  of this
Certificate, calculated using the exact method, is approximately 0.18423722%.

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

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

                       MORTGAGE PASS-THROUGH CERTIFICATES
                                  SERIES 1997-3

     This Certificate is one of a duly authorized  issue of Certificates  issued
in  several   Classes  and  Subclasses   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 the Servicer or the Trustee,  such advances are reimbursable to
the  Servicer  or the  Trustee to the extent  provided  in the  Agreement,  from
related recoveries on such Mortgage Loan or from other cash that would have been
distributable to Certificateholders.

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

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment of the Agreement and the modification of the rights and obligations of
the  Seller,  the  Master  Servicer  and  the  Trustee  and  the  rights  of the
Certificateholders  under the  Agreement  at any time by the Seller,  the Master
Servicer  and the  Trustee  with the  consent  of the  Holders  of  Certificates
evidencing  in the  aggregate  not less than 66 2/3% of the Voting  Interests of
each Class or Subclass of Certificates affected thereby. Any such consent by the
Holder of this  Certificate  shall be conclusive  and binding on such Holder and
upon all future holders of this  Certificate and of any Certificate  issued upon
the  transfer  hereof or in  exchange  hereof or in lieu  hereof  whether or not
notation  of such  consent  is made upon the  Certificate.  The  Agreement  also
permits the amendment  thereof in certain  circumstances  without the consent of
the Holders of any of the Certificates.

     As provided in the Agreement and subject to certain limitations therein set
forth,  the  transfer of this  Certificate  is  registrable  in the  Certificate
Register upon surrender of this  Certificate for registration of transfer at the
office or agency  appointed by the Trustee,  duly endorsed by, or accompanied by
an assignment in the form below or other written  instrument of transfer in form
satisfactory to the Trustee and the Certificate Registrar,  duly executed by the
Holder  hereof  or such  Holder's  attorney  duly  authorized  in  writing,  and
thereupon one or more new  Certificates of authorized  Denominations  evidencing
the same Class and Subclass 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 Subclass and aggregate Percentage  Interest,  as requested by the
Holder surrendering the same.

     No service  charge  will be made for any such  registration  of transfer or
exchange,  but the Trustee or the Certificate Registrar may require payment of a
sum  sufficient  to  cover  any tax or  other  governmental  charge  payable  in
connection therewith.

     The Seller, the Master Servicer, the Trustee and the Certificate Registrar,
and any agent of the Seller, the Master Servicer, the Trustee or the Certificate
Registrar,  may treat the Person in whose name this Certificate is registered as
the owner hereof for all purposes,  and neither the Seller, the Master Servicer,
the Trustee,  the Certificate  Registrar nor any such agent shall be affected by
notice to the contrary.

     The obligations created by the Agreement in respect of the Certificates and
the Trust Estate created  thereby shall  terminate upon the last action required
to be taken by the  Trustee  on the  Final  Distribution  Date  pursuant  to the
Agreement  following  the  earlier of (i) the payment or other  liquidation  (or
advance with respect  thereto) of the last Mortgage Loan subject  thereto or the
disposition  of all  property  acquired  upon  foreclosure  or  deed  in lieu of
foreclosure  of any Mortgage  Loan, and (ii) the purchase by the Seller from the
Trust  Estate of all  remaining  Mortgage  Loans and all  property  acquired  in
respect of such Mortgage Loans; provided, however, that the Trust Estate will in
no event  continue  beyond the expiration of 21 years from the death of the last
survivor of the  descendants  of Joseph P. Kennedy,  the late  ambassador of the
United  States to the Court of St. James,  living on the date of the  Agreement.
The  Agreement  permits,  but does not  require,  the  Seller  to  purchase  all
remaining  Mortgage  Loans and all property  acquired in respect of any Mortgage
Loan at a price  determined as provided in the  Agreement.  The exercise of such
option will effect early retirement of the  Certificates,  the Seller's right to
exercise such option being subject to the Pool  Scheduled  Principal  Balance of
the Mortgage Loans as of the  Distribution  Date upon which the proceeds of such
repurchase  are  distributed  being less than ten  percent of the  Cut-Off  Date
Aggregate Principal Balance.

and  agreements  hereinafter  set forth,  the  Trustee,  the Seller,  the Master
Servicer and the Custodian hereby agree as follows:

                                    ARTICLE I

                                   Definitions

     Capitalized  terms used in this Agreement and not defined herein shall have

otherwise required by the context herein.

                                   ARTICLE II

                          Custody of Mortgage Documents

     Section 2.1. Custodian to Act as Agent;  Acceptance of Custodial Files. The
Custodian,  as the duly  appointed  agent of the  Trustee  for  these  purposes,
acknowledges  receipt of the Mortgage Notes, the Mortgages,  the assignments and
other  documents  relating to the  Mortgage  Loans  identified  on the  schedule
attached  hereto and declares that it holds and will hold such  Mortgage  Notes,
Mortgages, assignments and other documents and any similar documents received by
the Trustee  subsequent to the date hereof (the "Custodial  Files") as agent for
the  Trustee,  in trust,  for the use and  benefit  of all  present  and  future
Certificateholders.

     Section 2.2. Recordation of Assignments. If any Custodial File includes one
or more assignments to the Trustee of Mortgage Notes and related  Mortgages that
have not been recorded, each such assignment shall be delivered by the Custodian
to the Seller for the purpose of recording it in the  appropriate  public office
for real property records, and the Seller, at no expense to the Custodian, shall
promptly cause to be recorded in the appropriate public office for real property
records each such  assignment and, upon receipt thereof from such public office,
shall return each such assignment to the Custodian.

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

     Section 2.4.  Notification of Breaches of  Representations  and Warranties.
Upon  discovery by the Custodian of a breach of any  representation  or warranty
made by the  Seller  or the  Master  Servicer  as set forth in the  Pooling  and
Servicing  Agreement,  the  Custodian  shall give prompt  written  notice to the
Seller, the Master Servicer and the Trustee.

     Section 2.5.  Custodian to Cooperate;  Release of Custodial Files. Upon the
payment in full of any Mortgage Loan, or the receipt by the Master Servicer of a
notification  that payment in full will be escrowed in an manner  customary  for
such purposes,  the Master Servicer shall immediately  notify the Custodian by a
certification  (which certification shall include a statement to the effect that
all amounts received or to be received in connection with such payment which are
required to be deposited in the Certificate  Account pursuant to Section 3.02 of
the Pooling and  Servicing  Agreement  have been or will be so  deposited)  of a
Servicing  Officer and shall request  delivery to it of the Custodial  File. The
Custodian agrees,  upon receipt of such  certification and request,  promptly to
release the related Custodial File to the Master Servicer.

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

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

                                   ARTICLE III

                            Concerning the Custodian

     Section 3.1.  Custodian a Bailee and Agent of the Trustee.  With respect to
each Mortgage Note,  Mortgage and other  documents  constituting  each Custodian
File which are  delivered to the  Custodian,  the Custodian is  exclusively  the
bailee  and agent of the  Trustee,  holds  such  documents  for the  benefit  of
Certificateholders and undertakes to perform such duties and only such duties as
are  specifically  set forth in this Agreement.  Except upon compliance with the
provisions of Section 2.5 of this Agreement, no Mortgage Note, Mortgage or other
document  constituting  a part of a  Custodial  File shall be  delivered  by the
Custodian to the Seller or the Master  Servicer or otherwise  released  from the
possession of the Custodian.

     Section 3.2.  Indemnification.  The Seller  hereby  agrees to indemnify and
hold the Custodian  harmless from and against all claims,  liabilities,  losses,
actions,  suits or proceedings at law or in equity, or any other expenses,  fees
or charges of any  character or nature,  which the  Custodian  may incur or with
which the  Custodian  may be  threatened  by reasons of its acting as  custodian
under this Agreement, including indemnification of the Custodian against any and
all expenses,  including  attorney's  fees if counsel for the Custodian has been
approved  by the  Seller,  and  the  cost  of  defending  any  action,  suit  or
proceedings  or  resisting  any  claim.  Notwithstanding  the  foregoing,  it is
specifically  understood and agreed that in the event any such claim, liability,
loss,  action,  suit or proceeding or other expense,  fees, or charge shall have
been caused by reason of any negligent act, negligent failure to act, or willful
misconduct  on the part of the  Custodian,  or which shall  constitute a willful
breach of its duties hereunder, the indemnification provisions of this Agreement
shall not apply.

     Section  3.3.  Custodian  May  Own  Certificates.   The  Custodian  in  its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Custodian.

     Section 3.4.  Master  Servicer to Pay  Custodian's  Fees and Expenses.  The
Master Servicer  covenants and agrees to pay to the Custodian from time to time,
and the Custodian shall be entitled to, reasonable compensation for all services
rendered by it in the exercise and  performance  of any of the powers and duties
hereunder of the  Custodian,  and the Master  Servicer will pay or reimburse the
Custodian  upon its  request  for all  reasonable  expenses,  disbursements  and
advances  incurred  or made  by the  Custodian  in  accordance  with  any of the
provisions of this  Agreement  (including the  reasonable  compensation  and the
expenses and  disbursements  of its counsel and of all persons not  regularly in
its employ), except any such expense,  disbursement or advance as may arise from
its negligence or bad faith.

     Section  3.5.  Custodian  May  Resign;  Trustee May Remove  Custodian.  The
Custodian may resign from the  obligations  and duties hereby imposed upon it as
such  obligations  and duties  relate to its acting as Custodian of the Mortgage
Loans. Upon receiving such notice of resignation,  the Trustee shall either take
custody of the  Custodial  Files  itself and give prompt  notice  thereof to the
Seller,  the Master  Servicer and the Custodian or promptly  appoint a successor
Custodian by written  instrument,  in  duplicate,  one copy of which  instrument
shall be  delivered to the  resigning  Custodian  and one copy to the  successor
Custodian.  If the Trustee shall not have taken  custody of the Custodial  Files
and no  successor  Custodian  shall  have been so  appointed  and have  accepted
resignation,  the  resigning  Custodian  may  petition  any  court of  competent
jurisdiction for the appointment of a successor Custodian.

     The  Trustee  may remove the  Custodian  at any time.  In such  event,  the
Trustee shall appoint, or petition a court of competent jurisdiction to appoint,
a successor Custodian  hereunder.  Any successor Custodian shall be a depository
institution  subject to supervision or examination by federal or state authority
and shall be able to satisfy the other requirements contained in Section 3.7.

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

     Section 3.6. Merger or  Consolidation  of Custodian.  Any Person into which
the Custodian  may be merged or converted or with which it may be  consolidated,
or any Person  resulting from any merger,  conversion or  consolidation to which
the Custodian shall be a party, or any Person  succeeding to the business of the
Custodian,  shall be the  successor  of the  Custodian  hereunder,  without  the
execution  or filing of any paper or any  further  act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

     Section  3.7.  Representations  of  the  Custodian.  The  Custodian  hereby
represents  that  it is a  depository  institution  subject  to  supervision  or
examination by a federal or state authority,  has a combined capital and surplus
of at least  $10,000,000 and is qualified to do business in the  jurisdiction in
which it will hold any Custodian File.

                                   ARTICLE IV

                            Miscellaneous Provisions

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

     Section 4.2.  Amendments.  No modification or amendment of or supplement to
this  Agreement  shall be valid or  effective  unless the same is in writing and
signed by all parties  hereto,  and neither the Seller,  the Master Servicer nor
the Trustee  shall enter into any  amendment  hereof  except as permitted by the
Pooling and  Servicing  Agreement.  The Trustee  shall give prompt notice to the
Custodian of any amendment or supplement to the Pooling and Servicing  Agreement
and furnish the Custodian with written copies thereof.

     Section 4.3.  Governing Law. This Agreement shall be deemed a contract made
under the laws of the State of New York and shall be  construed  and enforced in
accordance with and governed by the laws of the State of New York.

     Section  4.4.  Recordation  of  Agreement.   To  the  extent  permitted  by
applicable  law, this  Agreement is subject to  recordation  in all  appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated,  and in any other  appropriate  public  recording office or elsewhere,
such  recordation  to be effected by the Master  Servicer  and at its expense on
direction by the Trustee,  but only upon direction  accompanied by an Opinion of
Counsel to the effect that such recordation  materially and beneficially affects
the interests of the Certificateholders.

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

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

Certificate") for the account of, or as agent (including a broker,  nominee,  or
other  middleman)  for,  any person or entity from which it has not  received an
affidavit  substantially  in the form of this affidavit.  For these purposes,  a
"disqualified  organization"  means the United  States,  any state or  political
subdivision thereof, any foreign government, any international organization, any
agency or instrumentality of any of the foregoing (other than an instrumentality
if all of its  activities  are  subject  to tax and a  majority  of its board of
directors  is  not  selected  by  such  governmental  entity),  any  cooperative

respect to the Class A-R  Certificate  in excess of cash flows  generated by the

States is able to exercise primary  supervision over the  administration of such
trust,  and one or more United States  fiduciaries have the authority to control
all  substantial  decisions of such trust or (ii) for all other  taxable  years,

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

     9. That the Purchaser consents to the designation of the Master Servicer as
its agent to act as "tax matters  person" of the REMIC  pursuant to Section 3.01
of the Pooling and Servicing Agreement, and if such designation is not permitted

     (d) The Purchaser  confirms that (a) it has received and reviewed a copy of
the Private Placement  Memorandum dated February 24, 1997, relating to the Class
[B-3]  [B-4]  [B-5]   Certificates  and  reviewed,   to  the  extent  it  deemed
appropriate,  the  documents  attached  thereto  or  incorporated  by  reference
therein, (b) it has had the opportunity to ask questions of, and receive answers
from NASCOR concerning the Class [B-3] [B-4] [B-5]  Certificates and all matters

that NASCOR possesses or can possess without  unreasonable effort or expense and
(c) it has  undertaken  its own  independent  analysis of the  investment in the
Class [B-3] [B-4] [B-5] Certificates. The Purchaser will not use or disclose any
information it receives in connection with its purchase of the Class [B-3] [B-4]
[B-5]  Certificates  other than in  connection  with a subsequent  sale of Class
[B-3] [B-4] [B-5] Certificates.

fiduciary  responsibility  provisions 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 any  governmental  plan,  as defined in
Section  3(32) of ERISA  subject to any  federal,  state or local law  ("Similar
Law") which is, to a material  extent,  similar to the  foregoing  provisions of
ERISA or the Code (collectively, a "Plan"), an agent acting on behalf of a Plan,
or a  person  utilizing  the  assets  of a Plan or (ii) if the  Purchaser  is an
insurance company,  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)) and 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 or (iii) the Purchaser has provided (a) a
"Benefit  Plan  Opinion"  satisfactory  to NASCOR  and the  Trustee of the Trust
Estate  and (b) such other  opinions  of  counsel,  officers'  certificates  and
agreements as NASCOR 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 (a) cause the assets of the Trust Estate to be regarded as "plan assets" and
subject to the fiduciary  responsibility  provisions of ERISA or the  prohibited
transaction  provisions of the Code or Similar Law, (b) give rise to a fiduciary
duty under ERISA, Section 4975 of the Code or Similar Law on the part of NASCOR,
the Master  Servicer or the Trustee with respect to any Plan,  (c)  constitute a
prohibited transaction under ERISA or Section 4975 of the Code or Similar Law or
(d) subject the Trustee or the Depositor to any  obligation in addition to those
undertaken in the Trust Agreement.

     (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 [B-3] [B-4] [B-5] Certificates is in compliance therewith.

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

     (a) The Purchaser understands that the Class [B-3] [B-4] [B-5] 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 [B-3]
[B-4] [B-5]  Certificates  are registered under the Act and applicable state law
or unless an exemption from  registration  is available.  The Purchaser  further
understands  that neither  NASCOR,  the Master Servicer nor the Trustee is under
any obligation to register the Class [B-3] [B-4] [B-5]  Certificates  or make an
exemption available. In the event that such a transfer is to be made in reliance
upon an exemption  from the Act or applicable  state  securities  laws,  (i) the
Trustee shall require,  in order to assure  compliance  with such laws, that the
Certificateholder's  prospective transferee certify to NASCOR and the Trustee as
to the factual basis for the  registration  or  qualification  exemption  relied
upon, and (ii) unless the transferee is a "Qualified Institutional Buyer" within
the meaning of Rule 144A of the Act, the Trustee or NASCOR may, if such transfer
is made within  three  years from the later of (a) the  Closing  Date or (b) the
last  date  on  which  NASCOR  or any  affiliate  thereof  was a  holder  of the
Certificates proposed to be transferred, require an Opinion of Counsel that such
transfer may be made pursuant to an exemption from the Act and state  securities
laws,  which  Opinion of Counsel  shall not be an  expense of the  Trustee,  the
Master Servicer or NASCOR.  Any such  Certificateholder  desiring to effect such
transfer  shall,  and does hereby agree to,  indemnify  the Trustee,  the Master
Servicer,  any Paying Agent  acting on behalf of the Trustee and NASCOR  against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

     (b) No transfer of a Class  [B-3]  [B-4]  [B-5]  Certificate  shall be made
unless the  transferee  provides  NASCOR  and the  Trustee  with a  Transferee's
Letter, substantially in the form of this Agreement.

     (c)  The   Purchaser   acknowledges   that  its  Class  [B-3]  [B-4]  [B-5]
Certificates  bear  a  legend  setting  forth  the  applicable  restrictions  on
transfer.

                          SPECIAL SERVICING PROCEDURES

     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 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 the Servicer to an attorney  requesting
the institution of foreclosure.

     (b) If requested by the Purchaser,  the Company shall cause,  to the extent
that the Company as Master  Servicer is granted such  authority in the Servicing
Agreement,  the Servicer 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

to provide information that is readily accessible to its servicing personnel and
is non-confidential and (2) the Servicer shall respond within five Business Days
orally or in writing by facsimile transmission.

     (c) In addition to the  foregoing,  the Company shall cause,  to the extent
that the Company as Master  Servicer is granted such  authority in the Servicing
Agreement,  the Servicer 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 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  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 cause,  to the
extent that the  Company as Master  Servicer is granted  such  authority  in the
Servicing  Agreement,  the 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 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 Servicer) or (ii) if the
Servicer has reached the terms of a forbearance  agreement with the borrower. In
such latter case, the 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 Servicing  Agreement,  the Servicer to
delay  the  Commencement  of  Foreclosure  until  such  time  as  the  Purchaser
determines  that the 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  (i) be  provided  only to the  extent  it is not
confidential  in nature and (ii) is  obtainable  by the Servicer  from  existing
reports,  certificates  or statements or otherwise be 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 Servicer for all related
Monthly  Advances and  Liquidation  Expenses  thereafter made by the Servicer in
accordance with the Pooling and Servicing Agreement and the 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  therein 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 Servicing Agreement as of
the date hereof, 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  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
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 if immediately  available funds
from the Purchaser to the Company for deposit in the related Certificate Account
as  applicable;  or (ii) the  Servicer  may  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 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  Servicing  Agreement,  the  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 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 Servicing
Agreement as of the date hereof,  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 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 Servicing Agreement,  the 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,  the  Servicer,  or a Seller,  which may result in a
repurchase  or  substitution  of such  Mortgage  Loan,  or (iii) the  Company or
Servicer  reasonably believes the Mortgaged Property may be contaminated with or
affected by hazardous wastes or hazardous  substances (and, without limiting the
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 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
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 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 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) any breach
of the terms of this Agreement by the Purchaser.

     (b)  Except as set forth in  2.04(a),  this  Agreement  and the  respective
rights,  obligations  and  responsibilities  of the  Purchaser  and the  Company
hereunder shall  terminate upon the later to occur of (i) the final  liquidation
of the last Mortgage  Loan as to which the Purchaser  made any Election to Delay
Foreclosure  or any Election to Foreclose  and the  withdrawal  of all remaining
amounts in the  Collateral  Fund as provided  herein and (ii) ten Business Days'
notice.  The Purchaser's  right to make an election  pursuant to Section 2.02 or
Section 2.03 hereof with respect to a particular  Mortgage Loan shall  terminate
if the Purchaser fails to make any deposit required  pursuant to Section 2.02(d)
or 2.03(b) or if the Purchaser fails to make any other deposit to the Collateral
Fund pursuant to this Agreement.



                                   ARTICLE III

                       COLLATERAL FUND; SECURITY INTEREST

     Section 3.01. Collateral Fund

     Upon  receipt  from the  Purchaser  of the  initial  amount  required to be
deposited  in the  Collateral  Fund  pursuant to Article  II, the Company  shall
establish and maintain with Bankers Trust Company as a segregated account on its
books and records an account (the  "Collateral  Fund"),  entitled  "Norwest Bank
Minnesota,  National  Association,  as  Master  Servicer,  for  the  benefit  of
registered holders of Norwest Asset Securities Corporation Mortgage Pass-Through
Certificates,  Series 1997-3. Amounts held in the Collateral Fund shall continue
to be the  property of the  Purchaser,  subject to the first  priority  security
interest  granted  hereunder  for the benefit of the  Certificateholders,  until
withdrawn from the Collateral Fund pursuant to Section 2.02 or 2.03 hereof.  The
Collateral  Fund shall be an "outside  reserve  fund"  within the meaning of the
REMIC  Provisions,  beneficially  owned by the Purchaser for federal  income tax
purposes.  All income,  gain,  deduction or loss with respect to the  Collateral
Fund shall be that of the Purchaser.  All  distributions  from the Trust Fund to
the  Collateral  Fund shall be treated as  distributed  to the  Purchaser as the
beneficial owner thereof.

     Upon the  termination of this Agreement and the liquidation of all Mortgage
Loans as to which the  Purchaser has made any Election to Delay  Foreclosure  or
any Election to Foreclose  pursuant to Section  2.04 hereof,  the Company  shall
distribute 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 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.
