(1)      The Class PO  Certificates  will be Principal Only  Certificates  and
         will not bear interest.
(2)      The  Class  X  Certificates  will  be  Notional  Amount  Certificates
         comprised of two  Components.  Each  Component will have no principal
         balance and will bear interest on its Component  Notional Amount. The
         Notional Amount of the Class X Certificates on any Distribution  Date
         will equal the sum of the Component Notional Amounts of the Class X-1
         and Class X-2 Components, and will initially be $236,243,342.
(3)      The Pass-Through Rate for the Class X Certificates for any
         Distribution Date will be equal to the weighted average of the
         Pass-Through Rates of the Class X-1 and Class X-2 Components. The
         Pass-Through Rate for the Class X-1 Component for any Distribution
         Date will be equal to the excess of (a) the weighted average of the
         Adjusted Net Mortgage Rates of the Non-Discount Mortgage Loans in
         Loan Group 1 over (b) 6.50% per annum. The Pass-Through Rate for the
         Class X-2 Component for any Distribution Date will be equal to the
         excess of (a) the weighted average of the Adjusted Net Mortgage Rates
         of the Non-Discount Mortgage Loans in Loan Group 2 over (b) 6.50% per
         annum. The Pass-Through Rates for the Class X-1 and Class X-2
         Components for the first Distribution Date are 0.927% per annum and
         0.569% per annum, respectively.

                        REPRESENTATIONS AND WARRANTIES

Section 2.01.     Conveyance of Mortgage Loans.

         (a) The Seller,  concurrently with the execution and delivery hereof,
hereby  sells,  transfers,  assigns,  sets over and  otherwise  conveys to the

prior to the Closing  Date,  the Seller shall  deliver to the Depositor or, at

Such  delivery  of the  Mortgage  Files shall be made  against  payment by the
Depositor  of the  purchase  price,  previously  agreed to by the  Seller  and
Depositor, for the Mortgage Loans. With respect to any Mortgage Loan that does
not have a first  payment  date on or before  the Due Date in the month of the
first  Distribution  Date,  the Seller  shall  deposit  into the  Distribution
Account on the first Distribution  Account Deposit Date an amount equal to one
month's interest at the related Adjusted Net Mortgage Rate on the Cut-off Date
Principal  Balance of such Mortgage  Loan. If the Seller shall fail to deposit
such amount by the first Distribution  Account Deposit Date, the Trustee shall
deposit such amount.

         (b) The  Depositor,  concurrently  with the  execution  and  delivery
hereof, hereby sells,  transfers,  assigns, sets over and otherwise conveys to
the Trustee for the benefit of the  Certificateholders,  without recourse, all
the right,  title and  interest  of the  Depositor  in and to the Trust  Fund,
together with the  Depositor's  right to require the Seller to cure any breach
of a representation  or warranty made herein by the Seller or to repurchase or
substitute for any affected Mortgage Loan in accordance herewith.

         (c) In  connection  with the  transfer  and  assignment  set forth in
clause (b) above, the Depositor has delivered or caused to be delivered to the
Trustee for the benefit of the  Certificateholders  the following documents or
instruments with respect to each Mortgage Loan so assigned:

              (i) (A) the  original  Mortgage  Note,  endorsed  by  manual  or
         facsimile signature in blank in the following form: "Pay to the order
         of  ____________________________________  without recourse", with all
         intervening endorsements showing a complete chain of endorsement from
         the  originator to the Person  endorsing the Mortgage Note (each such
         endorsement  being  sufficient  to  transfer  all  right,  title  and
         interest  of the  party  so  endorsing,  as  noteholder  or  assignee
         thereof, in and to that Mortgage Note); or

                   (B) with  respect to any Lost  Mortgage  Note,  a lost note
              affidavit  from the Seller  stating that the  original  Mortgage
              Note  was  lost  or  destroyed,  together  with a copy  of  such
              Mortgage Note;

              (ii) except as provided below, the original recorded Mortgage or
         a copy of such Mortgage certified by the Seller (or, in the case of a
         Mortgage for which the related  Mortgaged  Property is located in the
         Commonwealth of Puerto Rico, a copy of such Mortgage certified by the
         applicable notary) as being a true and complete copy of the Mortgage;

              (iii) a duly executed  assignment of the Mortgage  (which may be
         included in a blanket  assignment  or  assignments),  together  with,
         except as provided below,  all interim  recorded  assignments of such
         mortgage (each such assignment,  when duly and validly completed,  to
         be in recordable  form and sufficient to effect the assignment of and
         transfer to the  assignee  thereof,  under the  Mortgage to which the
         assignment  relates);  provided that, if the related Mortgage has not
         been returned  from the  applicable  public  recording  office,  such
         assignment of the Mortgage may exclude the information to be provided
         by the recording  office;  provided,  further that such assignment of
         Mortgage  need not be  delivered  in the case of a Mortgage for which
         the  related  Mortgage  Property  is located in the  Commonwealth  of
         Puerto Rico.

              (iv) the  original or copies of each  assumption,  modification,

              (vi) in the case of a  Cooperative  Loan,  the  originals of the
         following documents or instruments:

                   (A) The Cooperative Shares,  together with a stock power in
              blank;

                   (B) The executed Security Agreement;

                   (C) The executed Proprietary Lease;

                   (D) The executed Recognition Agreement;

                   (E) The executed assignment of Recognition Agreement;

                   (F) The executed UCC-1 financing statement with evidence of
              recording  thereon which have been filed in all places  required
              to perfect the Seller's  interest in the Cooperative  Shares and
              the Proprietary Lease; and

                   (G)   Executed   UCC-3   financing   statements   or  other
              appropriate  UCC  financing  statements  required  by state law,
              evidencing a complete and  unbroken  line from the  mortgagee to
              the Trustee  with  evidence of  recording  thereon (or in a form
              suitable for recordation).

         In the event that in connection  with any Mortgage Loan the Depositor
cannot deliver (a) the original  recorded  Mortgage,  (b) all interim recorded
assignments  or (c) the  lender's  title  policy  (together  with  all  riders
thereto)  satisfying  the  requirements  of clause  (ii),  (iii) or (v) above,
respectively, concurrently with the execution and delivery hereof because such
document  or  documents  have not been  returned  from the  applicable  public
recording  office in the case of clause  (ii) or (iii)  above,  or because the
title  policy has not been  delivered  to either the  Master  Servicer  or the
Depositor by the applicable title insurer in the case of clause (v) above, the
Depositor shall promptly deliver to the Trustee, in the case of clause (ii) or
(iii) above,  such original Mortgage or such interim  assignment,  as the case
may be, with evidence of recording indicated thereon upon receipt thereof from
the public recording office, or a copy thereof,  certified, if appropriate, by
the relevant  recording office, but in no event shall any such delivery of the
original  Mortgage  Loan and each such interim  assignment  or a copy thereof,
certified,  if appropriate,  by the relevant  recording  office, be made later
than one year following the Closing Date, or, in the case of clause (v) above,
later than 120 days following the Closing Date; provided, however, that in the
event the  Depositor is unable to deliver by such date each  Mortgage and each
such interim assignment by reason of the fact that any such documents have not
been returned by the  appropriate  recording  office,  or, in the case of each
such interim assignment, because the related Mortgage has not been returned by
the appropriate  recording office,  the Depositor shall deliver such documents
to the Trustee as promptly as possible upon receipt thereof and, in any event,
within 720 days  following  the Closing Date.  The Depositor  shall forward or
cause to be forwarded to the Trustee (a) from time to time additional original
documents  evidencing an assumption or modification of a Mortgage Loan and (b)
any other  documents  required to be delivered by the  Depositor or the Master
Servicer  to the  Trustee.  In the event  that the  original  Mortgage  is not
delivered and in connection  with the payment in full of the related  Mortgage
Loan  the  public  recording  office  requires  the  presentation  of a  "lost
instruments affidavit and indemnity" or any equivalent document,  because only
a copy of the Mortgage can be delivered with the instrument of satisfaction or
reconveyance,  the Master  Servicer  shall  execute and deliver or cause to be
executed and delivered such a document to the public recording  office. In the
case where a public recording office retains the original recorded Mortgage or
in the case where a Mortgage is lost after  recordation in a public  recording
office,  the  Seller  shall  deliver  to the  Trustee a copy of such  Mortgage
certified by such public  recording  office to be a true and complete  copy of
the original recorded Mortgage.

         As  promptly  as   practicable   subsequent   to  such  transfer  and
assignment,  and in any event, within thirty (30) days thereafter, the Trustee
shall (i) affix the  Trustee's  name to each  assignment  of Mortgage,  as the
assignee  thereof,  (ii)  cause  such  assignment  to be in  proper  form  for
recording in the  appropriate  public office for real property  records within
thirty (30) days after  receipt  thereof and (iii) cause to be  delivered  for
recording  in the  appropriate  public  office for real  property  records the
assignments of the Mortgages to the Trustee,  except that, with respect to any
assignment  of a  Mortgage  as to  which  the  Trustee  has not  received  the
information  required to prepare  such  assignment  in  recordable  form,  the
Trustee's obligation to do so and to deliver the same for such recording shall
be as soon as practicable  after receipt of such  information and in any event
within  thirty (30) days after the receipt  thereof,  and the Trustee need not
cause to be recorded any  assignment  which relates to a Mortgage Loan (a) the
Mortgaged  Property  and  Mortgage  File  relating  to which  are  located  in
California or (b) in any other jurisdiction  (including Puerto Rico) under the
laws of which,  as evidenced by an Opinion of Counsel  delivered by the Seller
(at the Seller's  expense) to the Trustee,  the recordation of such assignment
is not necessary to protect the Trustee's and the Certificateholders' interest
in the related Mortgage Loan.

         In the case of  Mortgage  Loans that have been  prepaid in full as of
the Closing Date, the Depositor,  in lieu of delivering the above documents to
the  Trustee,  will  deposit in the  Certificate  Account  the portion of such
payment that is required to be deposited in the Certificate  Account  pursuant
to Section 3.08.

         (d) The Seller intends to treat the transfer of the Mortgage Loans to
the Depositor as a sale for all tax, accounting and regulatory purposes.

Section 2.02.     Acceptance by the Trustee of the Mortgage Loans.

                  The Trustee acknowledges receipt of the documents identified
in the  Initial  Certification  in the form  annexed  hereto as  Exhibit G and
declares that it holds and will hold such  documents  and the other  documents
delivered to it  constituting  the Mortgage  Files,  and that it holds or will
hold such other  assets as are  included in the Trust  Fund,  in trust for the
exclusive  use and benefit of all present and future  Certificateholders.  The
Trustee acknowledges that it will maintain possession of the Mortgage Notes in
the State of California, unless otherwise permitted by the Rating Agencies.

                  The  Trustee  agrees to execute  and  deliver on the Closing
Date  to the  Depositor,  the  Master  Servicer  and  the  Seller  an  Initial
Certification in the form annexed hereto as Exhibit G. Based on its review and
examination,  and  only  as  to  the  documents  identified  in  such  Initial
Certification,  the Trustee acknowledges that such documents appear regular on
their face and relate to such  Mortgage  Loan.  The Trustee  shall be under no
duty or obligation to inspect, review or examine said documents,  instruments,
certificates  or  other  papers  to  determine  that  the  same  are  genuine,
enforceable  or  appropriate  for the  represented  purpose  or that they have
actually been recorded in the real estate  records or that they are other than
what they purport to be on their face.

                  Not later than 90 days after the Closing  Date,  the Trustee
shall  deliver to the  Depositor,  the Master  Servicer and the Seller a Final
Certification  in the form  annexed  hereto as Exhibit H, with any  applicable
exceptions noted thereon.

                  If, in the  course of such  review,  the  Trustee  finds any
document  constituting  a part of a  Mortgage  File  which  does  not meet the
requirements  of Section 2.01,  the Trustee shall list such as an exception in
the Final Certification;  provided,  however,  that the Trustee shall not make
any  determination as to whether (i) any endorsement is sufficient to transfer
all right,  title and interest of the party so  endorsing,  as  noteholder  or
assignee  thereof,  in and to that Mortgage Note or (ii) any  assignment is in
recordable  form or is sufficient to effect the  assignment of and transfer to
the assignee thereof under the mortgage to which the assignment  relates.  The
Seller shall promptly correct or cure such defect within 90 days from the date
it was so  notified of such defect and, if the Seller does not correct or cure
such defect within such period, the Seller shall either (a) substitute for the
related Mortgage Loan a Substitute  Mortgage Loan, which substitution shall be
accomplished  in the manner and subject to the conditions set forth in Section
2.03, or (b) purchase such Mortgage Loan from the Trustee  within 90 days from
the date the Seller was  notified  of such  defect in writing at the  Purchase
Price of such Mortgage Loan;  provided,  however,  that in no event shall such
substitution  or  purchase  occur  more than 540 days from the  Closing  Date,
except that if the  substitution  or purchase of a Mortgage  Loan  pursuant to
this  provision is required by reason of a delay in delivery of any  documents
by the appropriate recording office, and there is a dispute between either the
Master  Servicer or the Seller and the Trustee  over the location or status of
the recorded  document,  then such substitution or purchase shall occur within
720 days from the Closing Date.  The Trustee shall deliver  written  notice to
each Rating  Agency  within 270 days from the  Closing  Date  indicating  each
Mortgage  Loan (a) which has not been  returned by the  appropriate  recording
office or (b) as to which  there is a dispute as to location or status of such
Mortgage Loan. Such notice shall be delivered  every 90 days thereafter  until
the related  Mortgage Loan is returned to the Trustee.  Any such  substitution
pursuant to (a) above or purchase  pursuant to (b) above shall not be effected
prior to the  delivery to the  Trustee of the  Opinion of Counsel  required by
Section 2.05, if any, and any substitution  pursuant to (a) above shall not be
effected  prior to the  additional  delivery  to the  Trustee of a Request for
Release  substantially  in the form of Exhibit N. No substitution is permitted
to be made in any calendar month after the Determination  Date for such month.
The Purchase Price for any such Mortgage Loan shall be deposited by the Seller
in the  Certificate  Account on or prior to the  Distribution  Account Deposit
Date for the Distribution  Date in the month following the month of repurchase
and, upon receipt of such deposit and  certification  with respect  thereto in
the form of Exhibit N hereto,  the Trustee shall release the related  Mortgage
File to the Seller and shall execute and deliver at the Seller's  request such
instruments  of transfer or  assignment  prepared by the Seller,  in each case
without recourse,  as shall be necessary to vest in the Seller, or a designee,
the Trustee's interest in any Mortgage Loan released pursuant hereto.

                  The  Trustee  shall  retain  possession  and custody of each
Mortgage File in accordance  with and subject to the terms and  conditions set
forth herein. The Master Servicer shall promptly deliver to the Trustee,  upon
the execution or receipt  thereof,  the  originals of such other  documents or
instruments  constituting the Mortgage File as come into the possession of the
Master Servicer from time to time.

                  It is  understood  and  agreed  that the  obligation  of the
Seller to substitute  for or to purchase any Mortgage Loan which does not meet
the requirements of Section 2.01 shall  constitute the sole remedy  respecting
such defect available to the Trustee, the Depositor and any  Certificateholder
against the Seller.

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

                   (a)  IndyMac,  in  its  capacities  as  Seller  and  Master
Servicer,  hereby  makes  the  representations  and  warranties  set  forth in
Schedule  II  hereto,  and  by  this  reference  incorporated  herein,  to the
Depositor and the Trustee, as of the Closing Date, or if so specified therein,
as of the Cut-off Date.

                   (b) The Seller, in its capacity as Seller, hereby makes the
representations  and warranties set forth in Schedule III hereto,  and by this
reference  incorporated  herein,  to the Depositor and the Trustee,  as of the
Closing Date, or if so specified therein, as of the Cut-off Date.

                   (c) Upon discovery by any of the parties hereto of a breach
of a  representation  or  warranty  made  pursuant  to  Section  2.03(b)  that
materially and adversely  affects the interests of the  Certificateholders  in
any Mortgage Loan, the party  discovering such breach shall give prompt notice
thereof to the other parties.  The Seller hereby covenants that within 90 days
of the  earlier of its  discovery  or its  receipt of written  notice from any
party of a breach of any  representation  or warranty made pursuant to Section
2.03(b)  which   materially  and  adversely   affects  the  interests  of  the
Certificateholders  in any  Mortgage  Loan,  it shall cure such  breach in all
material respects,  and if such breach is not so cured,  shall, (i) if such 90
day period expires prior to the second anniversary of the Closing Date, remove
such  Mortgage  Loan (a  "Deleted  Mortgage  Loan")  from the  Trust  Fund and
substitute in its place a Substitute  Mortgage Loan, in the manner and subject
to the  conditions  set forth in this Section  2.03;  or (ii)  repurchase  the
affected  Mortgage  Loan or Mortgage  Loans from the  Trustee at the  Purchase
Price  in the  manner  set  forth  below;  provided,  however,  that  any such
substitution pursuant to (i) above shall not be effected prior to the delivery
to the Trustee of the Opinion of Counsel required by Section 2.05, if any, and
a Request for Release substantially in the form of Exhibit N, and the Mortgage
File for any such  Substitute  Mortgage  Loan;  and provided,  further,  that,
anything  to  the  contrary  herein  notwithstanding,  Seller  shall  have  no
obligation to cure any such breach or to  repurchase  or  substitute  for such
affected  Mortgage Loan if the substance of such breach  constitutes  fraud in
the origination of such affected  Mortgage Loan and the Seller, at the time of
such  origination  and on the Closing Date,  did not have actual  knowledge of
such fraud.  The Seller shall promptly  reimburse the Master  Servicer and the
Trustee for any  expenses  reasonably  incurred by the Master  Servicer or the
Trustee in respect of enforcing the remedies for such breach.

                  With respect to any Substitute  Mortgage Loan or Loans,  the
Seller shall deliver to the Trustee for the benefit of the  Certificateholders
the Mortgage Note, the Mortgage,  the related assignment of the Mortgage,  and
such other  documents and agreements as are required by Section 2.01, with the
Mortgage Note endorsed and the Mortgage  assigned as required by Section 2.01.
No  substitution  is  permitted  to be made in any  calendar  month  after the
Determination  Date for such month.  Scheduled  Payments  due with  respect to
Substitute  Mortgage Loans in the month of  substitution  shall not be part of
the Trust  Fund and will be  retained  by the  Seller  on the next  succeeding
Distribution   Date.  For  the  month  of   substitution,   distributions   to
Certificateholders  will  include  the  monthly  payment  due on  any  Deleted
Mortgage  Loan for such month and  thereafter  the Seller shall be entitled to
retain all amounts received in respect of such Deleted Mortgage Loan.

                  The Master  Servicer  shall amend the Mortgage Loan Schedule
for the  benefit  of the  Certificateholders  to reflect  the  removal of such
Deleted Mortgage Loan and the substitution of the Substitute  Mortgage Loan or
Loans and the Master Servicer shall deliver the amended Mortgage Loan Schedule
to the Trustee. Upon such substitution,  the Substitute Mortgage Loan or Loans
shall be  subject  to the terms of this  Agreement  in all  respects,  and the
Seller shall be deemed to have made with respect to such  Substitute  Mortgage
Loan  or  Loans,  as of the  date of  substitution,  the  representations  and
warranties  made  pursuant to Section  2.03(b) with  respect to such  Mortgage
Loan. Upon any such substitution and the deposit to the Certificate Account of
the  amount  required  to  be  deposited   therein  in  connection  with  such
substitution  as  described  in the  following  paragraph,  the Trustee  shall
release  the  Mortgage  File held for the  benefit  of the  Certificateholders
relating to such  Deleted  Mortgage  Loan to the Seller and shall  execute and
deliver at the Seller's  direction such  instruments of transfer or assignment
prepared by the Seller, in each case without  recourse,  as shall be necessary
to vest title in the Seller,  or its designee,  the Trustee's  interest in any
Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

                  For any month in which the  Seller  substitutes  one or more
Substitute  Mortgage Loans for one or more Deleted  Mortgage Loans, the Master
Servicer will  determine the amount (if any) by which the aggregate  principal
balance of all such  Substitute  Mortgage Loans as of the date of substitution
is less  than the  aggregate  Stated  Principal  Balance  of all such  Deleted
Mortgage Loans (after  application of the scheduled  principal  portion of the
monthly  payments  due in the  month  of  substitution).  The  amount  of such
shortage (the  "Substitution  Adjustment  Amount") plus an amount equal to the
aggregate of any unreimbursed  Advances and Servicer  Advances with respect to
such Deleted Mortgage Loans shall be deposited into the Certificate Account by
the  Seller  on or  before  the  Distribution  Account  Deposit  Date  for the
Distribution  Date in the month succeeding the calendar month during which the
related Mortgage Loan became required to be purchased or replaced hereunder.

                  In the  event  that the  Seller  shall  have  repurchased  a
Mortgage  Loan,  the  Purchase  Price  therefor  shall  be  deposited  in  the
Certificate  Account  pursuant to Section  3.08 on or before the  Distribution
Account  Deposit Date for the  Distribution  Date in the month  following  the
month during which the Seller  became  obligated  hereunder to  repurchase  or
replace such  Mortgage Loan and upon such deposit of the Purchase  Price,  the
delivery of the Opinion of Counsel  required by Section  2.05 and receipt of a
Request for Release in the form of Exhibit N hereto, the Trustee shall release
the related  Mortgage File held for the benefit of the  Certificateholders  to
such  Person,  and the Trustee  shall  execute  and  deliver at such  Person's
direction such instruments of transfer or assignment  prepared by such Person,
in each case without  recourse,  as shall be necessary to transfer  title from
the  Trustee.  It is  understood  and agreed  that the  obligation  under this
Agreement of any Person to cure, repurchase or replace any Mortgage Loan as to
which a breach has occurred and is continuing shall constitute the sole remedy
against such Persons  respecting such breach available to  Certificateholders,
the Depositor or the Trustee on their behalf.

                  The  representations  and  warranties  made pursuant to this
Section 2.03 shall survive  delivery of the  respective  Mortgage Files to the
Trustee for the benefit of the Certificateholders.

Section 2.04.     Representations and Warranties of the Depositor as to 
                  the Mortgage  Loans.

                  The Depositor hereby  represents and warrants to the Trustee
with  respect to each  Mortgage  Loan as of the date hereof or such other date
set forth herein that as of the Closing  Date,  and  following the transfer of
the Mortgage  Loans to it by the Seller,  the  Depositor had good title to the
Mortgage Loans and the Mortgage Notes were subject to no offsets,  defenses or
counterclaims.

                  The Depositor  hereby assigns,  transfers and conveys to the
Trustee  all of its rights  with  respect  to the  Mortgage  Loans  including,
without  limitation,  the  representations  and  warranties of the Seller made
pursuant to Section  2.03(b),  together  with all rights of the  Depositor  to
require the Seller to cure any breach  thereof or to  repurchase or substitute
for any affected Mortgage Loan in accordance with this Agreement.

                  It is  understood  and agreed that the  representations  and
warranties  set forth in this  Section  2.04  shall  survive  delivery  of the
Mortgage Files to the Trustee.

Section 2.05.     Delivery of Opinion of Counsel in Connection with 
                  Substitutions and Repurchases.

                   (a)   Notwithstanding   any  contrary   provision  of  this
Agreement, no substitution pursuant to Section 2.02 or 2.03 shall be made more
than 90 days after the Closing Date unless the Seller  delivers to the Trustee
an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of
either the Trustee or the Trust Fund,  addressed to the Trustee, to the effect
that such  substitution  will not (i) result in the  imposition  of the tax on
"prohibited transactions" on the Trust Fund or contributions after the Startup
Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code,  respectively
or (ii)  cause the REMIC  hereunder  to fail to qualify as a REMIC at any time
that any Certificates are outstanding.

                   (b) Upon discovery by the Depositor, the Seller, the Master
Servicer,  or the  Trustee  that  any  Mortgage  Loan  does not  constitute  a
"qualified mortgage" within the meaning of Section 860G(a)(3) of the Code, the
party  discovering  such fact shall promptly (and in any event within five (5)
Business Days of discovery)  give written notice thereof to the other parties.
In connection therewith, the Trustee shall require the Seller, at the Seller's
option,  to either (i)  substitute,  if the conditions in Section 2.03(c) with
respect to  substitutions  are satisfied,  a Substitute  Mortgage Loan for the
affected  Mortgage Loan, or (ii) repurchase the affected  Mortgage Loan within
90 days of such discovery in the same manner as it would a Mortgage Loan for a
breach of  representation  or  warranty  made  pursuant to Section  2.03.  The
Trustee shall reconvey to the Seller the Mortgage Loan to be released pursuant
hereto in the same manner, and on the same terms and conditions, as it would a
Mortgage Loan repurchased for breach of a representation or warranty contained
in Section 2.03.

Section 2.06.     Execution and Delivery of Certificates.

                  The Trustee  acknowledges  the transfer and assignment to it
of the Trust Fund and,  concurrently  with such transfer and  assignment,  has
executed and delivered to or upon the order of the Depositor, the Certificates
in  authorized  denominations  evidencing  directly or  indirectly  the entire
ownership  of the Trust Fund.  The  Trustee  agrees to hold the Trust Fund and
exercise  the rights  referred  to above for the  benefit of all  present  and
future Holders of the Certificates and to perform the duties set forth in this
Agreement  to the best of its  ability,  to the end that the  interests of the
Holders of the Certificates may be adequately and effectively protected.

Section 2.07.     REMIC Matters.

                  The Preliminary  Statement sets forth the  designations  and
"latest  possible  maturity  date" for  federal  income  tax  purposes  of all
interests  created  hereby.  The  "Startup  Day"  for  purposes  of the  REMIC
Provisions shall be the Closing Date. The "tax matters person" with respect to
the REMIC  hereunder  shall be the Trustee and the Trustee  shall hold the Tax
Matters  Person  Certificate.  The REMIC's  fiscal year shall be the  calendar
year.

                                 ARTICLE III

                         ADMINISTRATION AND SERVICING
                               OF MORTGAGE LOANS

Section 3.01.     Master Servicer to Service Mortgage Loans.

                  For and on  behalf  of the  Certificateholders,  the  Master
Servicer shall service and  administer  the Mortgage Loans in accordance  with
the terms of this  Agreement and the Servicing  Standard.  In connection  with
such servicing and  administration,  the Master Servicer shall have full power
and authority,  acting alone and/or  through  Servicers as provided in Section
3.02, to do or cause to be done any and all things that it may deem  necessary
or desirable in connection with such servicing and  administration,  including
but not limited to, the power and authority,  subject to the terms hereof, (i)
to execute and deliver, on behalf of the  Certificateholders  and the Trustee,
customary  consents or waivers and other  instruments  and documents,  (ii) to
consent to transfers of any Mortgaged Property and assumptions of the Mortgage
Notes  and  related  Mortgages  (but  only  in the  manner  provided  in  this
Agreement),  (iii) to collect any  Insurance  Proceeds  and other  Liquidation
Proceeds,  and  (iv) to  effectuate  foreclosure  or other  conversion  of the
ownership of the Mortgaged  Property  securing any Mortgage  Loan.  The Master
Servicer shall not make or permit any modification, waiver or amendment of any
term of any Mortgage  Loan which would cause the REMIC to fail to qualify as a
REMIC or result in the imposition of any tax under Section  860F(a) or Section
860G(d) of the Code.  Without  limiting the generality of the  foregoing,  the
Master  Servicer,  in its own  name  or in the  name  of any  Servicer  or the
Depositor and the Trustee, is hereby authorized and empowered by the Depositor
and the Trustee, when the Master Servicer or the Servicer, as the case may be,
believes it appropriate in its reasonable judgment, to execute and deliver, on
behalf of the Trustee, the Depositor,  the  Certificateholders or any of them,
any and all instruments of satisfaction or cancellation, or of partial or full
release or discharge,  and all other comparable  instruments,  with respect to
the Mortgage Loans, and with respect to the Mortgaged  Properties held for the
benefit of the  Certificateholders.  The Master  Servicer  shall  prepare  and
deliver to the Depositor and/or the Trustee such documents requiring execution
and  delivery by either or both of them as are  necessary  or  appropriate  to
enable the Master Servicer to service and administer the Mortgage Loans to the
extent that the Master  Servicer is not  permitted to execute and deliver such
documents pursuant to the preceding sentence.  Upon receipt of such documents,
the Depositor and/or the Trustee shall execute such documents and deliver them
to the Master Servicer.

                  In  accordance  with  and to  the  extent  of the  Servicing
Standard,  the Master  Servicer shall advance or cause to be advanced funds as
necessary for the purpose of effecting the payment of taxes and assessments on
the Mortgaged  Properties,  which advances shall be  reimbursable in the first
instance  from related  collections  from the  Mortgagors  pursuant to Section
3.09,  and  further as  provided in Section  3.11.  The costs  incurred by the
Master  Servicer,  if any,  in  effecting  the  timely  payments  of taxes and
assessments on the Mortgaged  Properties and related insurance  premiums shall
not,   for  the  purpose  of   calculating   monthly   distributions   to  the
Certificateholders,  be added to the Stated Principal  Balances of the related
Mortgage  Loans,  notwithstanding  that the  terms of such  Mortgage  Loans so
permit.

Section 3.02.     Subservicing; Enforcement of the Obligations of Servicers.

                   (a) The Master Servicer may arrange for the subservicing of
any Mortgage Loan by a Servicer pursuant to a Servicing  Agreement;  provided,
however,  that such  subservicing  arrangement  and the  terms of the  related
subservicing  agreement  must provide for the servicing of such Mortgage Loans
in a manner consistent with the servicing arrangements contemplated hereunder.
Each Servicer of a Mortgage  Loan shall be entitled to receive and retain,  as
provided in the related  Servicing  Agreement and in Section 3.17, the related
Servicing Fee from  payments of interest  received on such Mortgage Loan after
payment of all  amounts  required  to be  remitted  to the Master  Servicer in
respect  of  such  Mortgage  Loan.  Unless  the  context  otherwise  requires,
references  in this  Agreement  to actions  taken or to be taken by the Master
Servicer in servicing the Mortgage Loans include  actions taken or to be taken
by a Servicer on behalf of the Master Servicer.  Each Servicing Agreement will
be based upon such terms and conditions as are generally required or permitted
by the Seller/Servicer  Guide and are not inconsistent with this Agreement and
as the Master Servicer and the Servicer have agreed.  With the approval of the
Master  Servicer,  a  Servicer  may  delegate  its  servicing  obligations  to
third-party  servicers,  but such  Servicer  will remain  obligated  under the
related Servicing  Agreement.  The Master Servicer and Servicer may enter into
amendments to the related Servicing Agreement or a different form of Servicing
Agreement;  provided,  however,  that any such  amendments or different  forms
shall be  consistent  with and not  violate  the  provisions  of  either  this
Agreement or the Seller/Servicer  Guide in a manner which would materially and
adversely affect the interests of the Certificateholders.

                   (b) For  purposes of this  Agreement,  the Master  Servicer
shall be deemed to have received any collections,  recoveries or payments with
respect to the Mortgage  Loans that are received by a Servicer  regardless  of
whether such payments are remitted by the Servicer to the Master Servicer.

                   (c) As  part of its  servicing  activities  hereunder,  the
Master  Servicer,  for the benefit of the Trustee and the  Certificateholders,
shall use its best  reasonable  efforts to  enforce  the  obligations  of each
Servicer  under  the  related  Servicing  Agreement,  to the  extent  that the
non-performance  of any such obligation would have material and adverse effect
on a Mortgage Loan. Such enforcement, including, without limitation, the legal
prosecution of claims,  termination of Servicing Agreements and the pursuit of
other appropriate  remedies,  shall be in such form and carried out to such an
extent and at such time as the  Master  Servicer,  in its good faith  business
judgment,  would require were it the owner of the related  Mortgage Loans. The
Master  Servicer  shall pay the costs of such  enforcement at its own expense,
and shall be reimbursed  therefor only (i) from a general  recovery  resulting
from such  enforcement to the extent,  if any, that such recovery  exceeds all
amounts  due in respect of the related  Mortgage  Loan or (ii) from a specific
recovery of costs,  expenses or attorneys  fees against the party against whom
such enforcement is directed.

Section 3.03.     Successor Servicers.

                  The Master  Servicer  shall be  entitled  to  terminate  any
Servicing Agreement that may exist in accordance with the terms and conditions
of such  Servicing  Agreement  and  without any  limitation  by virtue of this
Agreement;  provided,  however,  that  in  the  event  of  termination  of any
Servicing  Agreement  by the  Master  Servicer  or the  Servicer,  the  Master
Servicer  shall either act as servicer of the related  Mortgage  Loan or enter
into a Servicing  Agreement  with a successor  Servicer which will be bound by
the terms of the related  Servicing  Agreement.  If the Master Servicer or any
affiliate  of the  Master  Servicer  acts  as  servicer,  it will  not  assume
liability for the  representations  and  warranties  of the Servicer  which it
replaces.  If the Master  Servicer  enters into a Servicing  Agreement  with a
successor  Servicer,  the Master Servicer shall use reasonable efforts to have
the successor Servicer assume liability for the representations and warranties
made by the terminated  Servicer in respect of the related Mortgage Loans and,
in the event of any such  assumption  by the  successor  Servicer,  the Master
Servicer may, in the exercise of its business judgment, release the terminated
Servicer from liability for such representations and warranties.

Section 3.04.     Liability of the Master Servicer.

                  Notwithstanding   any  Servicing   Agreement,   any  of  the
provisions of this Agreement  relating to agreements or  arrangements  between
the Master  Servicer or a Servicer or  references  to actions  taken through a
Servicer or otherwise,  the Master Servicer shall remain  obligated and liable
to the Trustee and  Certificateholders  for the servicing and administering of
the Mortgage  Loans in accordance  with the provisions of Section 3.01 without
diminution  of such  obligation  or  liability  by  virtue  of such  Servicing
Agreements or arrangements or by virtue of  indemnification  from the Servicer
and to the same  extent  and under the same  terms  and  conditions  as if the
Master Servicer alone were servicing and administering the Mortgage Loans. The
Master  Servicer shall be entitled to enter into any agreement with a Servicer
or Seller for  indemnification of the Master Servicer and nothing contained in
this Agreement shall be deemed to limit or modify such indemnification.

Section 3.05.     No Contractual Relationship Between Servicers and the Trustee.

                  Any  Servicing  Agreement  that may be entered  into and any
other  transactions  or services  relating to the Mortgage  Loans  involving a
Servicer in its capacity as such and not as an  originator  shall be deemed to
be between  the  Servicer  and the Master  Servicer  alone and the Trustee and
Certificateholders  shall  not be deemed  parties  thereto  and shall  have no
claims,  rights,  obligations,  duties  or  liabilities  with  respect  to the
Servicer in its capacity as such except as set forth in Section 3.07.

Section 3.06.     Rights of the Depositor and the Trustee in Respect 
                  of the Master Servicer.

                  The  Depositor  may, but is not  obligated  to,  enforce the
obligations of the Master Servicer hereunder and may, but is not obligated to,
perform,  or cause a designee  to perform,  any  defaulted  obligation  of the
Master Servicer hereunder and in connection with any such defaulted obligation
to exercise the related rights of the Master Servicer hereunder; provided that
the Master Servicer shall not be relieved of any of its obligations  hereunder
by virtue of such  performance  by the Depositor or its designee.  Neither the
Trustee nor the Depositor shall have any  responsibility  or liability for any
action or failure to act by the Master  Servicer  nor shall the Trustee or the
Depositor be obligated to supervise  the  performance  of the Master  Servicer
hereunder or otherwise.

Section 3.07.     Trustee to Act as Master Servicer.

                  In the event that the Master  Servicer  shall for any reason
no longer be the Master Servicer hereunder (including by reason of an Event of
Default),  the  Trustee or its  successor  shall  thereupon  assume all of the
rights and obligations of the Master  Servicer  hereunder  arising  thereafter
(except  that the  Trustee  shall not be (i)  liable  for losses of the Master
Servicer  pursuant to Section 3.12 or any acts or omissions of the predecessor
Master  Servicer  hereunder),  (ii)  obligated  to  make  Advances  if  it  is
prohibited  from doing so by  applicable  law,  (iii)  obligated to effectuate
repurchases or substitutions  of Mortgage Loans  hereunder,  including but not
limited to repurchases or substitutions pursuant to Section 2.02 or 2.03, (iv)
responsible  for expenses of the Master  Servicer  pursuant to Section 2.03 or
(v)  deemed to have made any  representations  and  warranties  of the  Master
Servicer  hereunder.  Any such assumption shall be subject to Section 7.02. If
the Master  Servicer  shall for any  reason no longer be the  Master  Servicer
(including  by reason of any Event of Default),  the Trustee or its  successor
shall succeed to any rights and  obligations of the Master Servicer under each
Servicing  Agreement.  The Trustee or the  successor  servicer for the Trustee
shall be deemed to have assumed all of the Master Servicer's  interest therein
and to have replaced the Master Servicer as a party to any Servicing Agreement
entered  into by the Master  Servicer as  contemplated  by Section 3.02 to the
same extent as if the  Servicing  Agreement  had been assigned to the assuming
party except that the Master  Servicer  shall not be relieved of any liability
or obligations under any such Servicing Agreement.

                  The Master Servicer shall, upon request of the Trustee,  but
at the  expense of the Master  Servicer,  deliver  to the  assuming  party all
documents  and records  relating to each  Servicing  Agreement  or  substitute
servicing  agreement and the Mortgage Loans then being serviced thereunder and
an  accounting  of amounts  collected or held by it and otherwise use its best
efforts  to effect  the  orderly  and  efficient  transfer  of the  substitute
Servicing Agreement to the assuming party.

Section 3.08.     Collection of Mortgage Loan Payments; Servicing Accounts; 
                  Collection Account; Certificate Account; Distribution Account.

                   (a) In  accordance  with and to the extent of the Servicing
Standard, the Master Servicer shall make reasonable efforts in accordance with
the customary and usual standards of practice of prudent mortgage servicers to
collect all payments called for under the terms and provisions of the Mortgage
Loans to the extent such  procedures  shall be consistent  with this Agreement
and the  terms  and  provisions  of any  related  Required  Insurance  Policy.
Consistent  with the foregoing,  the Master Servicer may in its discretion (i)
waive any late payment charge or any prepayment  charge or penalty interest in
connection  with the  prepayment  of a Mortgage  Loan and (ii)  extend the due
dates for  payments  due on a Mortgage  Note for a period not greater than 125
days; provided,  however,  that the Master Servicer cannot extend the maturity
of any such  Mortgage  Loan past the date on which the final payment is due on
the latest maturing  Mortgage Loan as of the Cut-off Date. In the event of any
such  arrangement,  the Master  Servicer  shall make  Advances  on the related
Mortgage  Loan in  accordance  with the  provisions of Section 4.01 during the
scheduled period in accordance with the amortization schedule of such Mortgage
Loan without modification  thereof by reason of such arrangements.  The Master
Servicer shall not be required to institute or join in litigation with respect
to  collection  of any payment  (whether  under a Mortgage,  Mortgage  Note or
otherwise or against any public or  governmental  authority  with respect to a
taking or condemnation) if it reasonably believes that enforcing the provision
of the Mortgage or other instrument pursuant to which such payment is required
is prohibited by applicable law.

                   (b) In those cases where a Servicer is  servicing  Mortgage
Loans pursuant to a Servicing  Agreement,  the Master Servicer shall cause the
Servicer,  pursuant to the Servicing Agreement,  to establish and maintain one
or more Servicing  Accounts,  each of which shall be an Eligible Account.  The
Servicer will be required  under its  Servicing  Agreement to deposit into the
Servicing  Account on a daily basis no later than the Business  Day  following
receipt,  all proceeds of Mortgage  Loans  received by the Servicer,  less its
Servicing Fees and unreimbursed  Servicer Advances and expenses, to the extent
permitted by the Servicing  Agreement.  The Servicer  shall not be required to
deposit in the  Servicing  Account  payments or  collections  in the nature of
prepayment charges or late charges.

                   (c) The Master  Servicer  shall  establish  and  maintain a
Collection Account into which the Master Servicer shall deposit or cause to be
deposited on or before each Withdrawal Date payments, collections and Servicer
Advances remitted by Servicers in respect of the Mortgage Loans.

                   (d) On or  before  the  Withdrawal  Date in  each  calendar
month, the Master Servicer shall cause the Servicer, pursuant to the Servicing
Agreement,  to remit to the Master  Servicer  for  deposit  in the  Collection
Account all funds held in the Servicing  Account with respect to each Mortgage
Loan  serviced by such Servicer that are required to be remitted to the Master
Servicer.  The  Servicer  will also be  required,  pursuant  to the  Servicing
Agreement,  to advance on or before each such Withdrawal Date amounts equal to
any Scheduled  Payments (net of its Servicing  Fees with respect  thereto) not
received on any  Mortgage  Loans by the  Servicer  (such  amount,  a "Servicer
Advance").  The Servicer's obligation to advance with respect to each Mortgage
Loan will continue up to and  including  the first day of the month  following
the date on which the related Mortgaged Property is sold at a foreclosure sale
or is acquired by the Trust Fund by deed in lieu of  foreclosure or otherwise.
All such Servicer  Advances received by the Master Servicer shall be deposited
promptly  by it in the  Collection  Account  or the  Certificate  Account,  as
appropriate.

                  Within five Business Days after the receipt by a Servicer of
a  Principal  Prepayment  in Full or any  Liquidation  Proceeds  or  Insurance
Proceeds  (not  required  to be  applied to the  restoration  or repair of the
related  Mortgaged  Property),  the Master Servicer shall cause such Servicer,
pursuant  to the related  Servicing  Agreement,  to remit such  amounts to the
Master Servicer for deposit in the Collection Account.

                   (e) The Master  Servicer  shall  establish  and  maintain a
Certificate  Account into which the Master  Servicer shall deposit or cause to
be deposited  on a daily basis  within one Business Day of receipt,  except as
otherwise specifically provided herein, the following payments and collections
remitted  by  Servicers  or  received  by  it in  respect  of  Mortgage  Loans
subsequent  to the  Cut-off  Date  (other  than in  respect of  principal  and
interest  due on the  Mortgage  Loans on or before the  Cut-off  Date) and the
following amounts required to be deposited hereunder:

                        (i)  all  payments  on  account  of  principal  on the
Mortgage Loans, including Principal Prepayments and the principal component of
any Servicer Advance;

                        (ii)  all  payments  on  account  of  interest  on the
Mortgage Loans, net of the sum of the related Master Servicing Fee and related
Servicing Fee, and the interest component of any Servicer Advance;

                        (iii) all Insurance Proceeds and Liquidation  Proceeds
(net of any related expenses of the related Servicer),  other than proceeds to
be applied to the restoration or repair of the Mortgaged  Property or released
to the Mortgagor in accordance  with the Master  Servicer's  normal  servicing
procedures;

                        (iv) any amount required to be deposited by the Master
Servicer  pursuant  to  Section  3.08(g)  in  connection  with any  losses  on
Permitted Investments;

                        (v) any amounts required to be deposited by the Master
Servicer pursuant to Sections 3.12 and 3.14;

                        (vi) all Purchase  Prices from the Master  Servicer or
Seller and all Substitution Adjustment Amounts;

                        (vii)  all  Advances  made  by  the  Master   Servicer
pursuant to Section 4.01; and

                        (viii)  any other  amounts  required  to be  deposited
hereunder.

                  In  addition,  with  respect  to any  Mortgage  Loan that is
subject to a buydown  agreement,  on each Due Date for such Mortgage  Loan, in
addition to the monthly payment remitted by the Mortgagor, the Master Servicer
shall cause funds to be deposited  into the  Certificate  Account in an amount
required  to cause an  amount of  interest  to be paid  with  respect  to such
Mortgage  Loan  equal to the  amount  of  interest  that has  accrued  on such
Mortgage  Loan from the  preceding  Due Date at the  Mortgage  Rate net of the
Master Servicing Fee on such date.

                  The  foregoing  requirements  for  remittance  by the Master
Servicer  shall be exclusive,  it being  understood  and agreed that,  without
limiting the generality of the foregoing, payments in the nature of prepayment
penalties,  late payment charges or assumption fees, if collected, need not be
remitted by the Master  Servicer.  In the event that the Master Servicer shall
remit any amount not required to be remitted,  it may at any time  withdraw or
direct the institution  maintaining  the Certificate  Account to withdraw such
amount from the  Certificate  Account,  any  provision  herein to the contrary
notwithstanding.   Such   withdrawal  or  direction  may  be  accomplished  by
delivering  written  notice  thereof to the Trustee or such other  institution
maintaining the Certificate  Account which describes the amounts  deposited in
error in the Certificate  Account. The Master Servicer shall maintain adequate
records with respect to all  withdrawals  made  pursuant to this Section 3.08.
All funds deposited in the Certificate  Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.11.

                   (f) The Trustee shall establish and maintain,  on behalf of
the Certificateholders,  the Distribution Account. The Trustee shall, promptly
upon  receipt,  deposit in the  Distribution  Account  and retain  therein the
following:

                        (i)  the  aggregate  amount  remitted  by  the  Master
Servicer to the Trustee pursuant to Section 3.11(a);

                        (ii)  any  amount  deposited  by the  Master  Servicer
pursuant  to  Section  3.08(g)  in  connection  with any  losses on  Permitted
Investments; and

                        (iii) any other amounts deposited  hereunder which are
required to be deposited in the Distribution Account.

                  In the event that the Master Servicer shall remit any amount
not required to be remitted, it may at any time direct the Trustee to withdraw
such  amount  from the  Distribution  Account,  any  provision  herein  to the
contrary notwithstanding.  Such direction may be accomplished by delivering an
Officer's  Certificate to the Trustee which describes the amounts deposited in
error in the  Distribution  Account.  All funds deposited in the  Distribution
Account shall be held by the Trustee in trust for the Certificateholders until
disbursed in accordance  with this  Agreement or withdrawn in accordance  with
Section 3.11. In no event shall the Trustee  incur  liability for  withdrawals
from the Distribution Account at the direction of the Master Servicer.

                   (g) Each  institution at which the  Certificate  Account or
the  Distribution  Account is  maintained  shall  invest the funds  therein as
directed in writing by the Master  Servicer in  Permitted  Investments,  which
shall mature not later than (i) in the case of the  Certificate  Account,  the
second  Business Day next preceding the related  Distribution  Account Deposit
Date  (except  that if  such  Permitted  Investment  is an  obligation  of the
institution that maintains such account,  then such Permitted Investment shall
mature  not later  than the  Business  Day next  preceding  such  Distribution
Account Deposit Date) and (ii) in the case of the  Distribution  Account,  the
Business  Day  next  preceding  the  Distribution  Date  (except  that if such
Permitted  Investment is an obligation of the institution  that maintains such
account,  then such  Permitted  Investment  shall  mature  not later than such
Distribution  Date) and, in each case,  shall not be sold or disposed of prior
to its maturity.  All such Permitted  Investments shall be made in the name of
the Trustee,  for the benefit of the  Certificateholders.  All income and gain
(net of any losses)  realized from any such  investment of funds on deposit in
the Certificate  Account or the Distribution  Account shall be for the benefit
of the Master Servicer as servicing  compensation  and shall be remitted to it
monthly  as  provided  herein.  The  amount  of  any  realized  losses  in the
Certificate  Account or the Distribution  Account incurred in any such account
in respect of any such  investments  shall promptly be deposited by the Master
Servicer in the  Certificate  Account or paid to the Trustee for deposit  into
the Distribution Account, as applicable. The Trustee in its fiduciary capacity
shall not be liable  for the  amount of any loss  incurred  in  respect of any
investment or lack of investment of funds held in the  Certificate  Account or
the Distribution Account and made in accordance with this Section 3.08.

                   (h) The Master  Servicer  shall give notice to the Trustee,
the Seller, each Rating Agency and the Depositor of any proposed change of the
location of the  Certificate  Account not later than 30 days and not more than
45 days prior to any change  thereof.  The  Trustee  shall give  notice to the
Master  Servicer,  the Seller,  each Rating  Agency and the  Depositor  of any
proposed change of the location of the Distribution  Account not later than 30
days and not more than 45 days prior to any change thereof.

Section 3.09.     Collection of Taxes, Assessments and Similar 
                  Items; Escrow Accounts.

                   (a) To the extent required by the related Mortgage Note and
not violative of current law, the Master Servicer shall cause each Servicer to
establish and maintain one or more accounts  (each,  an "Escrow  Account") and
deposit and retain therein all collections from the Mortgagors (or advances by
the Servicer) for the payment of taxes, assessments, hazard insurance premiums
or comparable  items for the account of the  Mortgagors.  Nothing herein shall
require the Master Servicer or any Servicer to compel a Mortgagor to establish
an Escrow Account in violation of applicable law.

                   (b)  Withdrawals  of amounts so  collected  from the Escrow
Accounts  may be made only to effect  timely  payment  of taxes,  assessments,
hazard insurance premiums,  condominium or PUD association dues, or comparable
items, to reimburse the Master Servicer or the related Servicer out of related
collections  for any payments  made pursuant to Sections 3.12 (with respect to
taxes and assessments and insurance premiums) and 3.13 (with respect to hazard
insurance), to refund to any Mortgagors any sums determined to be overages, to
pay  interest,  if  required  by law or the terms of the  related  Mortgage or
Mortgage Note, to Mortgagors on balances in the Escrow Account or to clear and
terminate  the  Escrow  Account  at  the  termination  of  this  Agreement  in
accordance  with Section 9.01. The Escrow  Accounts shall not be a part of the
Trust Fund.

                   (c) The Master Servicer shall advance any payments referred
to in Section  3.09(a) that are not timely paid by the  Mortgagors or advanced
by the  Servicers  on the date when the tax,  premium  or other cost for which
such payment is intended is due, but the Master  Servicer shall be required so
to advance only to the extent that such  advances,  in the good faith judgment
of the Master  Servicer,  will be  recoverable  by the Master  Servicer out of
Insurance Proceeds, Liquidation Proceeds or otherwise.

Section 3.10.     Access to Certain Documentation and Information 
                  Regarding the Mortgage Loans.

                  The  Master  Servicer  shall  afford,  or  shall  cause  the
Servicers to afford,  the Depositor and the Trustee  reasonable  access to all
records and  documentation  regarding  the  Mortgage  Loans and all  accounts,
insurance  information  and other  matters  relating to this  Agreement,  such
access being afforded  without charge,  but only upon  reasonable  request and
during normal business hours at the office designated by the Master Servicer.

                  Upon  reasonable  advance  notice  in  writing,  the  Master
Servicer  will  provide,  or will  cause the  Servicers  to  provide,  to each
Certificateholder  which is a savings and loan association,  bank or insurance
company certain reports and reasonable access to information and documentation
regarding the Mortgage Loans  sufficient to permit such  Certificateholder  to
comply with applicable  regulations of the OTS or other regulatory authorities
with  respect to  investment  in the  Certificates;  provided  that the Master
Servicer  and any  Servicer  shall be entitled to be  reimbursed  by each such
Certificateholder  for actual expenses incurred by the Master Servicer or such
Servicer in providing such reports and access.

                  The Master  Servicer  shall  provide to the OTS and the FDIC
and to comparable regulatory  authorities  supervising Holders of Subordinated
Certificates and the examiners and supervisory agents of the OTS, the FDIC and
such other  authorities,  access to the  documentation  regarding the Mortgage
Loans required by applicable  regulations of the OTS and the FDIC. Such access
shall be afforded only upon  reasonable  and prior written  request and during
normal business hours at the offices designated by the Master Servicer. Unless
prohibited  by applicable  laws or  regulations,  the Master  Servicer and any
Servicer shall be entitled to be reimbursed by the related  Certificateholders
for actual  expenses  incurred  by the Master  Servicer  or such  Servicer  in
providing such access. Nothing in this Section 3.10 shall limit the obligation
of the Master Servicer to observe any applicable law prohibiting disclosure of
information regarding the Mortgagors and the failure of the Master Servicer or
any Servicer to provide access as provided in this Section 3.10 as a result of
such obligation shall not constitute a breach of this Section 3.10.

Section 3.11.     Permitted Withdrawals from the Certificate Account 
                  and the Distribution Account.

                   (a)  The  Master  Servicer  may  from  time  to  time  make
withdrawals from the Certificate Account for the following purposes:

                        (i)  to  pay to the  Master  Servicer  or the  related
Servicer (to the extent not previously retained),  the servicing  compensation
to which it is  entitled  pursuant to Section  3.17,  and to pay to the Master
Servicer,  as  additional  master  servicing  compensation,   earnings  on  or
investment  income with  respect to funds in or  credited  to the  Certificate
Account;

                        (ii) to reimburse  the Master  Servicer or the related
Servicer for unreimbursed Advances or Servicer Advances made by it, such right
of  reimbursement  pursuant to this  subclause  (ii) being  limited to amounts
received  on the  Mortgage  Loan(s) in  respect  of which any such  Advance or
Servicer Advance was made;

                        (iii)  to  reimburse  the  Master   Servicer  for  any
Nonrecoverable Advance previously made;

                        (iv) to  reimburse  the Master  Servicer  for  Insured
Expenses from the related Insurance Proceeds;

                        (v)  to   reimburse   the  Master   Servicer  for  (a)
unreimbursed  Servicing Advances, the Master Servicer's right to reimbursement
pursuant to this clause (a) with respect to any Mortgage Loan being limited to
amounts  received on such Mortgage  Loan(s) which represent late recoveries of
the payments  for which such  advances  were made  pursuant to Section 3.01 or
Section 3.09 and (b) for unpaid Master  Servicing  Fees as provided in Section
3.14;

                        (vi) to pay to the  purchaser,  with  respect  to each
Mortgage Loan or property  acquired in respect thereof that has been purchased
pursuant to Section  2.02,  2.03,  3.14(a),  3.14(b) or  3.14(c),  all amounts
received thereon after the date of such purchase;

                        (vii) to reimburse the Seller,  the Master Servicer or
the Depositor for expenses  incurred by any of them and reimbursable  pursuant
to Section 6.03;

                        (viii)  to  withdraw  any  amount   deposited  in  the
Certificate Account and not required to be deposited therein;

                        (ix) on or prior to the  Distribution  Account Deposit
Date,  to withdraw  an amount  equal to the  related  Available  Funds and the
Trustee Fee for such  Distribution  Date, to the extent on deposit,  and remit
such amount to the Trustee for deposit in the Distribution Account; and

                        (x) to clear and  terminate  the  Certificate  Account
upon termination of this Agreement pursuant to Section 9.01.

                  The  Master  Servicer  shall  keep  and  maintain   separate
accounting,  on a Mortgage  Loan by Mortgage  Loan  basis,  for the purpose of
justifying  any  withdrawal  from the  Certificate  Account  pursuant  to such
subclauses (i), (ii),  (iv), (v) and (vi). Prior to making any withdrawal from
the Certificate Account pursuant to subclause (iii), the Master Servicer shall
deliver  to the  Trustee  an  Officer's  Certificate  of a  Servicing  Officer
indicating  the  amount  of any  previous  Advance  determined  by the  Master
Servicer to be a  Nonrecoverable  Advance and identifying the related Mortgage
Loan(s) and their respective portions of such Nonrecoverable Advance.

                   (b) The Trustee shall withdraw funds from the  Distribution
Account for  distributions to  Certificateholders,  in the manner specified in
this  Agreement  (and to withhold  from the amounts so withdrawn the amount of
any taxes that it is authorized to withhold  pursuant to the last paragraph of
Section 8.11). In addition, the Trustee may from time to time make withdrawals
from the Distribution Account for the following purposes:

                        (i) to pay to itself the  Trustee  Fee for the related
Distribution Date;

                        (ii)  to pay  to the  Master  Servicer  as  additional
servicing  compensation earnings on or investment income with respect to funds
in the Distribution Account;

                        (iii) to  withdraw  and return to the Master  Servicer
any amount  deposited  in the  Distribution  Account  and not  required  to be
deposited therein; and

                        (iv) to clear and terminate the  Distribution  Account
upon termination of the Agreement pursuant to Section 9.01.

Section 3.12.     Maintenance of Hazard Insurance; Maintenance of 
                  Primary Insurance Policies.

                        (a) The Master  Servicer shall cause to be maintained,
for each Mortgage Loan,  hazard insurance with extended  coverage in an amount
that is at least equal to the lesser of (i) the maximum insurable value of the
improvements  securing  such  Mortgage  Loan or (ii)  the  greater  of (y) the
outstanding principal balance of the Mortgage Loan and (z) an amount such that
the  proceeds  of such policy  shall be  sufficient  to prevent the  Mortgagor
and/or the mortgagee from becoming a co-insurer.  Each such policy of standard
hazard  insurance  shall contain,  or have an  accompanying  endorsement  that
contains,  a  standard  mortgagee  clause.  To the extent it may do so without
breaching the related Servicing  Agreement,  the Master Servicer shall replace
any  Servicer  that  does  not  cause  such  insurance,  to the  extent  it is
available,  to be  maintained.  Any amounts  collected by the Master  Servicer
under  any  such  policies  (other  than  the  amounts  to be  applied  to the
restoration or repair of the related Mortgaged Property or amounts released to
the  Mortgagor  in  accordance  with the Master  Servicer's  normal  servicing
procedures)  shall be  deposited  in the  Certificate  Account or the  related
Servicing Account, as applicable.  Any cost incurred by the Master Servicer or
any Servicer in maintaining  any such insurance  shall not, for the purpose of
calculating monthly distributions to the  Certificateholders or remittances to
the  Trustee  for their  benefit,  be added to the  principal  balance  of the
Mortgage Loan,  notwithstanding that the terms of the Mortgage Loan so permit.
Such costs shall be recoverable by the Master Servicer out of late payments by
the related  Mortgagor or out of Liquidation  Proceeds to the extent permitted
by Section  3.11.  It is  understood  and agreed that no  earthquake  or other
additional  insurance  is to be required of any  Mortgagor  or  maintained  on
property  acquired  in  respect  of a Mortgage  other  than  pursuant  to such
applicable  laws and regulations as shall at any time be in force and as shall
require such additional insurance. If the Mortgaged Property is located at the
time of  origination  of the Mortgage Loan in a federally  designated  special
flood  hazard  area and  such  area is  participating  in the  national  flood
insurance  program,  the Master  Servicer  shall cause flood  insurance  to be
maintained  with respect to such Mortgage Loan.  Such flood insurance shall be
in an amount equal to the least of (i) the original  principal  balance of the
related Mortgage Loan, (ii) the replacement  value of the  improvements  which
are part of such  Mortgaged  Property,  and (iii) the  maximum  amount of such
insurance  available  for the related  Mortgaged  Property  under the national
flood insurance program.

                  In the event  that the  Master  Servicer  shall  obtain  and
maintain  a  blanket  policy  insuring  against  hazard  losses  on all of the
Mortgage  Loans,  it  shall  conclusively  be  deemed  to have  satisfied  its
obligations  as set forth in the first sentence of this Section 3.12, it being
understood  and agreed  that such policy may  contain a  deductible  clause on
terms substantially  equivalent to those commercially available and maintained
by comparable  servicers.  If such policy  contains a deductible  clause,  the
Master  Servicer shall, in the event that there shall not have been maintained
on the related  Mortgaged  Property a policy complying with the first sentence
of this  Section  3.12,  and there shall have been a loss that would have been
covered by such  policy,  deposit in the  Certificate  Account  the amount not
otherwise payable under the blanket policy because of such deductible  clause.
In connection  with its activities as Master  Servicer of the Mortgage  Loans,
the Master Servicer agrees to present, on behalf of itself, the Depositor, and
the Trustee for the benefit of the  Certificateholders,  claims under any such
blanket policy.

                        (b) The Master  Servicer shall not take, or permit any
Servicer to take,  any action  which would  result in  non-coverage  under any
applicable  Primary Insurance Policy of any loss which, but for the actions of
the Master Servicer or any Servicer,  would have been covered thereunder.  The
Master Servicer shall not cancel or refuse to renew any such Primary Insurance
Policy  that  is in  effect  at  the  date  of  the  initial  issuance  of the
Certificates  and is  required  to be  kept  in  force  hereunder  unless  the
replacement  Primary Insurance Policy for such canceled or non-renewed  policy
is  maintained  with a Qualified  Insurer.  The Master  Servicer  shall not be
required to  maintain  any Primary  Insurance  Policy (i) with  respect to any
Mortgage Loan with a  Loan-to-Value  Ratio less than or equal to 80% as of any
date of determination  or, based on a new appraisal,  the principal balance of
such Mortgage Loan  represents 80% or less of the new Appraised  Value or (ii)
if maintaining such Primary  Insurance Policy is prohibited by applicable law.
The Master  Servicer  agrees,  to the extent  permitted by applicable  law, to
effect the timely  payment of the premiums on each Primary  Insurance  Policy,
and such costs not otherwise  recoverable  shall be  recoverable by the Master
Servicer from the related liquidation proceeds.

                  In connection  with its activities as Master Servicer of the
Mortgage Loans,  the Master  Servicer agrees to present,  or cause the related
Servicer   to   present,   on  behalf  of   itself,   the   Trustee   and  the
Certificateholders, claims to the insurer under any Primary Insurance Policies
and, in this regard,  to take such  reasonable  action in accordance  with the
Servicing  Standard as shall be necessary to permit recovery under any Primary
Insurance Policies respecting  defaulted Mortgage Loans. Any amounts collected
by a Servicer  or the Master  Servicer  under any Primary  Insurance  Policies
shall be deposited in the Servicing  Account,  the  Collection  Account or the
Certificate Account, as applicable.

Section 3.13.     Enforcement of Due-On-Sale Clauses; Assumption Agreements.

                        (a) Except as otherwise provided in this Section 3.13,
when any property  subject to a Mortgage has been  conveyed by the  Mortgagor,
the Master  Servicer or the related  Servicer shall, to the extent that it has
knowledge of such  conveyance and in accordance  with the Servicing  Standard,
enforce any due-on-sale clause contained in any Mortgage Note or Mortgage,  to
the extent permitted under applicable law and  governmental  regulations,  but
only to the  extent  that  such  enforcement  will  not  adversely  affect  or
jeopardize  coverage under any Required Insurance Policy.  Notwithstanding the
foregoing, neither the Master Servicer nor the related Servicer is required to
exercise such rights with respect to a Mortgage Loan if the Person to whom the
related  Mortgaged  Property  has been  conveyed or is proposed to be conveyed
satisfies the terms and conditions contained in the Mortgage Note and Mortgage
related  thereto and the consent of the mortgagee  under such Mortgage Note or
Mortgage is not otherwise so required  under such Mortgage Note or Mortgage as
a condition to such transfer. In the event that (i) the Master Servicer or the
related  Servicer is  prohibited by law from  enforcing  any such  due-on-sale
clause,  (ii) coverage under any Required  Insurance Policy would be adversely
affected,  (iii) the Mortgage  Note does not include a  due-on-sale  clause or
(iv) nonenforcement is otherwise permitted  hereunder,  the Master Servicer is
authorized,  subject to Section  3.13(b),  to take or enter into an assumption
and  modification  agreement from or with the person to whom such property has
been or is about to be conveyed,  pursuant to which such person becomes liable
under the Mortgage Note and,  unless  prohibited by applicable  state law, the
Mortgagor  remains  liable  thereon,  provided  that the  Mortgage  Loan shall
continue to be covered (if so covered before the Master  Servicer  enters such
agreement) by the applicable Required Insurance Policies. The Master Servicer,
subject to Section 3.13(b),  is also authorized with the prior approval of the
insurers under any Required Insurance Policies to enter into a substitution of
liability agreement with such Person, pursuant to which the original Mortgagor
is released  from  liability and such Person is  substituted  as Mortgagor and
becomes liable under the Mortgage  Note.  Notwithstanding  the foregoing,  the
Master  Servicer  shall not be deemed to be in default under this Section 3.13
by reason of any transfer or assumption  which the Master Servicer  reasonably
believes it is restricted by law from preventing, for any reason whatsoever.

                        (b) Subject to the Master  Servicer's  duty to enforce
any due-on-sale clause to the extent set forth in Section 3.13(a), in any case
in which a Mortgaged  Property  has been  conveyed to a Person by a Mortgagor,
and such  Person is to enter  into an  assumption  agreement  or  modification
agreement or  supplement  to the Mortgage  Note or Mortgage  that requires the
signature of the Trustee, or if an instrument of release signed by the Trustee
is required  releasing the Mortgagor  from liability on the Mortgage Loan, the
Master  Servicer  shall  prepare  and  deliver  or  cause to be  prepared  and
delivered  to the Trustee for  signature  and shall  direct,  in writing,  the
Trustee  to  execute  the  assumption  agreement  with the  Person to whom the
Mortgaged  Property  is to be  conveyed  and such  modification  agreement  or
supplement  to the  Mortgage  Note or  Mortgage  or other  instruments  as are
reasonable  or  necessary  to  carry  out the  terms of the  Mortgage  Note or
Mortgage or otherwise to comply with any applicable laws regarding assumptions
or the transfer of the Mortgaged  Property to such Person.  In connection with
any such assumption,  no material term of the Mortgage Note may be changed. In
addition,  the  substitute  Mortgagor  and  the  Mortgaged  Property  must  be
acceptable  to  the  Master  Servicer  in  accordance  with  its  underwriting
standards as then in effect. Together with each such substitution,  assumption
or other agreement or instrument delivered to the Trustee for execution by it,
the  Master  Servicer  shall  deliver  an  Officer's  Certificate  signed by a
Servicing  Officer stating that the  requirements of this subsection have been
met in connection  therewith.  The Master Servicer shall notify,  or cause the
related  Servicer  to  notify,  the  Trustee  that  any such  substitution  or
assumption  agreement  has been  completed  by  forwarding  to the Trustee the
original of such  substitution or assumption  agreement,  which in the case of
the original  shall be added to the related  Mortgage File and shall,  for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof. Any fee collected
by the Master  Servicer or any  Servicer for entering  into an  assumption  or
substitution of liability agreement will be retained by the Master Servicer as
additional master servicing compensation.

Section 3.14.     Realization Upon Defaulted Mortgage Loans; Repurchase 
                  of Certain Mortgage Loans.

                        (a) The Master  Servicer shall use reasonable  efforts
in  accordance  with the  Servicing  Standard to  foreclose  upon or otherwise
comparably  convert the ownership of Mortgaged  Properties in respect of which
the related  Mortgage  Loans come into and continue in default and as to which
no  satisfactory  arrangements  can  be  made  for  collection  of  delinquent
payments. In connection with such foreclosure or other conversion,  the Master
Servicer shall follow the Servicing Standard and shall follow the requirements
of the insurer under any Required Insurance Policy;  provided,  however,  that
the Servicer may enter into, and shall give the Rating  Agencies  notice of, a
special  servicing  agreement with an  unaffiliated  holder of 100% Percentage
Interest of one or more Classes of Subordinated  Certificates or a holder of a
class  of  securities  representing  interests  in  one  or  more  Classes  of
Subordinated  Certificates  and  provided,  further,  that  entering into such
special servicing  agreement shall not result in the downgrading or withdrawal
of the  respective  ratings  when  assigned  to  the  Certificates.  Any  such
agreement may contain provisions whereby such holder may instruct the Servicer
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.  Notwithstanding  the
foregoing,  the Master  Servicer shall not be required to expend its own funds
in connection  with any foreclosure or towards the restoration of any property
unless it shall determine (i) that such  restoration  and/or  foreclosure will
increase the proceeds of liquidation of the Mortgage Loan after  reimbursement
to itself of such expenses and (ii) that such expenses will be  recoverable to
it through Liquidation  Proceeds  (respecting which it shall have priority for
purposes of withdrawals  from the  Certificate  Account).  The Master Servicer
shall be  responsible  for all other costs and expenses  incurred by it in any
such   proceedings;   provided,   however,   that  it  shall  be  entitled  to
reimbursement  thereof  from the  liquidation  proceeds  with  respect  to the
related  Mortgaged  Property,  as provided in the  definition  of  Liquidation
Proceeds. If the Master Servicer has knowledge that a Mortgaged Property which
the Master  Servicer is  contemplating  acquiring in foreclosure or by deed in
lieu of  foreclosure  is located  within a 1 mile radius of any site listed in
the Expenditure Plan for the Hazardous  Substance Clean Up Bond Act of 1984 or
other site with  environmental  or  hazardous  waste risks known to the Master
Servicer, the Master Servicer will, prior to acquiring the Mortgaged Property,
consider  such risks and only take action in accordance  with its  established
environmental review procedures.

                  With respect to any REO Property, the deed or certificate of
sale  shall  be  taken  in the  name of the  Trustee  for the  benefit  of the
Certificateholders,  or its nominee, on behalf of the Certificateholders.  The
Trustee's name shall be placed on the title to such REO Property solely as the
Trustee  hereunder and not in its  individual  capacity.  The Master  Servicer
shall  ensure that the title to such REO Property  references  the Pooling and
Servicing  Agreement and the  Trustee's  capacity  hereunder.  Pursuant to its
efforts to sell such REO Property,  the Master Servicer shall either itself or
through an agent selected by the Master Servicer protect and conserve such REO
Property in accordance  with the Servicing  Standard and may,  incident to its
conservation and protection of the interests of the  Certificateholders,  rent
the same, or any part thereof,  as the Master Servicer deems to be in the best
interest of the  Certificateholders  for the period  prior to the sale of such
REO Property. The Master Servicer shall prepare for and deliver to the Trustee
a statement with respect to each REO Property that has been rented showing the
aggregate rental income received and all expenses  incurred in connection with
the  management  and  maintenance  of such REO  Property  at such  times as is
necessary to enable the Trustee to comply with the reporting  requirements  of
the REMIC  Provisions.  The net monthly rental  income,  if any, from such REO
Property shall be deposited in the Certificate Account no later than the close
of business on each Determination  Date. The Master Servicer shall perform the
tax reporting and withholding  required by Sections 1445 and 6050J of the Code
with respect to foreclosures and abandonments,  the tax reporting  required by
Section  6050H of the Code with  respect to the receipt of  mortgage  interest
from individuals and, if required by Section 6050P of the Code with respect to
the cancellation of indebtedness by certain financial  entities,  by preparing
such tax and information returns as may be required, in the form required, and
delivering the same to the Trustee for filing.

                  In the event  that the Trust  Fund  acquires  any  Mortgaged
Property as aforesaid or  otherwise in  connection  with a default or imminent
default  on a  Mortgage  Loan,  the  Master  Servicer  shall  dispose  of such
Mortgaged  Property  prior to three years after its  acquisition  by the Trust
Fund unless the Trustee shall have been supplied with an Opinion of Counsel to
the  effect  that the  holding by the Trust  Fund of such  Mortgaged  Property
subsequent  to such  three-year  period will not result in the  imposition  of
taxes on "prohibited  transactions" on the REMIC as defined in section 860F of
the Code or cause the REMIC to fail to qualify as a REMIC at any time that any
Certificates  are  outstanding,  in which case the Trust Fund may  continue to
hold such  Mortgaged  Property  (subject to any  conditions  contained in such
Opinion of Counsel). Notwithstanding any other provision of this Agreement, no
Mortgaged  Property  acquired by the Trust Fund shall be rented (or allowed to
continue to be rented) or otherwise used for the production of income by or on
behalf of the Trust Fund in such a manner or  pursuant to any terms that would
(i) cause such Mortgaged Property to fail to qualify as "foreclosure property"
within the meaning of Section 860G(a)(8) of the Code or (ii) subject the REMIC
to the  imposition  of any federal,  state or local income taxes on the income
earned  from such  Mortgaged  Property  under  Section  860G(c) of the Code or
otherwise,  unless  the  Master  Servicer  has  agreed to  indemnify  and hold
harmless the Trust Fund with respect to the imposition of any such taxes.

                  The  decision  of the  Master  Servicer  to  foreclose  on a
defaulted  Mortgage  Loan shall be subject  to a  determination  by the Master
Servicer  that the  proceeds of such  foreclosure  would  exceed the costs and
expenses of bringing such a proceeding.  The income earned from the management
of any  REO  Properties,  net of  reimbursement  to the  Master  Servicer  for
expenses  incurred  (including any property or other taxes) in connection with
such management and net of unreimbursed Master Servicing Fees, Servicing Fees,
Advances,  Servicer Advances and Servicing  Advances,  shall be applied to the
payment of principal of and interest on the related  defaulted  Mortgage Loans
(with  interest  accruing as though such Mortgage Loans were still current and
adjustments, if applicable, to the Mortgage Rate were being made in accordance
with the terms of the Mortgage Note) and all such income shall be deemed,  for
all purposes in this  Agreement,  to be payments on account of  principal  and
interest  on the  related  Mortgage  Notes  and  shall be  deposited  into the
Certificate Account. To the extent the net income received during any calendar
month is in excess of the amount  attributable  to  amortizing  principal  and
accrued interest at the related Mortgage Rate on the related Mortgage Loan for
such  calendar  month,  such  excess  shall  be  considered  to  be a  partial
prepayment of principal of the related Mortgage Loan.

                  The proceeds  from any  liquidation  of a Mortgage  Loan, as
well as any income  from an REO  Property,  will be  applied in the  following
order of  priority:  first,  to reimburse  the Master  Servicer or the related
Servicer for any related  unreimbursed  Servicing  Advances,  Master Servicing
Fees and  Servicing  Fees,  as  applicable;  second,  to reimburse  the Master
Servicer or the related  Servicer  for any  unreimbursed  Advances or Servicer
Advances,  as  applicable,  and to reimburse the  Certificate  Account for any
Nonrecoverable  Advances (or portions thereof) that were previously  withdrawn
by the Master Servicer  pursuant to Section  3.11(a)(iii) that related to such
Mortgage Loan; third, to accrued and unpaid interest (to the extent no Advance
or  Servicer  Advance  has been made for such  amount or any such  Advance  or
Servicer  Advance has been  reimbursed)  on the  Mortgage  Loan or related REO
Property,  at the Adjusted Net Mortgage Rate to the Due Date  occurring in the
month in which such amounts are required to be distributed;  and fourth,  as a
recovery of principal of the Mortgage Loan. Excess Proceeds,  if any, from the
liquidation  of a  Liquidated  Mortgage  Loan will be  retained  by the Master
Servicer as additional servicing compensation pursuant to Section 3.17.

                        (b) The Master Servicer, in its sole discretion, shall
have the  right to  purchase  for its own  account  from  the  Trust  Fund any
Mortgage  Loan  which is 91 days or more  delinquent  at a price  equal to the
Purchase Price.  The Purchase Price for any Mortgage Loan purchased  hereunder
shall be deposited in the Certificate Account and the Trustee, upon receipt of
a certificate from the Master Servicer in the form of Exhibit N hereto,  shall
release or cause to be released to the  purchaser  of such  Mortgage  Loan the
related  Mortgage  File and shall  execute and  deliver  such  instruments  of
transfer or assignment  prepared by the  purchaser of such  Mortgage  Loan, in
each case without recourse,  as shall be necessary to vest in the purchaser of
such  Mortgage  Loan  any  Mortgage  Loan  released  pursuant  hereto  and the
purchaser of such  Mortgage  Loan shall  succeed to all the  Trustee's  right,
title and interest in and to such Mortgage Loan and all security and documents
related thereto.  Such assignment shall be an assignment  outright and not for
security.  The  purchaser  of such  Mortgage  Loan  shall  thereupon  own such
Mortgage Loan, and all security and documents,  free of any further obligation
to the Trustee or the Certificateholders with respect thereto.

                        (c) The Master Servicer may agree to a modification of
any  Mortgage  Loan (the  "Relevant  Mortgage  Loan")  upon the request of the
related Mortgagor,  provided that the modification is in lieu of a refinancing
and  the  Mortgage  Rate  on the  Relevant  Mortgage  Loan,  as  modified,  is
approximately  a prevailing  market rate for  newly-originated  mortgage loans
having  similar  terms and (ii) the Master  Servicer  purchases  the  Relevant
Mortgage Loan from the Trust Fund as described  below.  Effective  immediately
after such modification,  and, in any event, on the same Business Day on which
the modification  occurs,  all right, title and interest of the Trustee in and
to the Modified  Mortgage Loan shall  automatically be deemed  transferred and
assigned to the Master  Servicer  and all  benefits  and burdens of  ownership
thereof,  including  without  limitation the right to accrued interest thereon
from and including the date of modification  and the risk of default  thereon,
shall pass to the Master Servicer.  The Master Servicer shall promptly deliver
to the Trustee a certification  of a Servicing  Officer to the effect that all
requirements of the first paragraph of this subsection (c) have been satisfied
with respect to such Modified Mortgage Loan.

                  The Master Servicer shall deposit the Purchase Price for any
Modified Mortgage Loan in the Certificate  Account pursuant to Section 3.08(e)
within one  Business Day after the purchase of such  Modified  Mortgage  Loan.
Upon receipt by the Trustee of written notification of any such deposit signed
by a Servicing  Officer,  the Trustee shall release to the Master Servicer the
related  Mortgage  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  Master  Servicer  any  Modified  Mortgage  Loan  previously
transferred and assigned pursuant hereto.

                  The Master  Servicer  covenants  and agrees to indemnify the
REMIC against any and all liability for any "prohibited transaction" taxes and
any related interest, additions and penalties imposed on the REMIC established
hereunder as a result of any modification of a Mortgage Loan effected pursuant
to this subsection  (c), any holding of a Modified  Mortgage Loan by the REMIC
or any purchase of a Modified  Mortgage Loan by the Master  Servicer (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 payment of such tax, if permitted
by law,  pending the outcome of such  proceedings).  The Master Servicer shall
have no right of  reimbursement  for any amount paid pursuant to the foregoing
indemnification, except to the extent that the amount of any tax, interest and
penalties,  together  with interest  thereon,  is refunded to the REMIC or the
Master Servicer.

Section 3.15.     Trustee to Cooperate; Release of Mortgage Files.

                  Upon  the  payment  in full  of any  Mortgage  Loan,  or the
receipt by the Master Servicer of a notification  that payment in full will be
escrowed in a manner  customary for such  purposes,  the Master  Servicer will
immediately  notify the Trustee by delivering,  or causing to be delivered,  a
"Request for Release"  substantially in the form of Exhibit N. Upon receipt of
such request,  the Trustee shall promptly release the related Mortgage File to
the Master Servicer,  and the Trustee shall at the Master Servicer's direction
execute and deliver to the Master Servicer the request for reconveyance,  deed
of  reconveyance  or release or  satisfaction  of mortgage or such  instrument
releasing  the  lien of the  Mortgage  in each  case  provided  by the  Master
Servicer,   together  with  the  Mortgage   Note  with  written   evidence  of
cancellation  thereon.  Expenses incurred in connection with any instrument of
satisfaction  or deed of  reconveyance  shall  be  chargeable  to the  related
Mortgagor.  From time to time and as shall be appropriate for the servicing or
foreclosure of any Mortgage Loan,  including for such purpose collection under
any  policy of flood  insurance,  any  fidelity  bond or  errors or  omissions
policy,  or for the purposes of effecting a partial  release of any  Mortgaged
Property from the lien of the Mortgage or the making of any corrections to the
Mortgage  Note or the Mortgage or any of the other  documents  included in the
Mortgage File,  the Trustee  shall,  upon delivery to the Trustee of a Request
for  Release in the form of Exhibit M signed by a Servicing  Officer,  release
the  Mortgage  File  to the  Master  Servicer  or,  at the  Master  Servicer's
direction,  to the related  Servicer.  Subject to the further  limitations set
forth below, the Master Servicer shall cause the Mortgage File or documents so
released to be returned  to the Trustee  when the need  therefor by the Master
Servicer no longer  exists,  unless the Mortgage  Loan is  liquidated  and the
proceeds thereof are deposited in the Certificate  Account,  in which case the
Master Servicer shall deliver to the Trustee a Request for Release in the form
of Exhibit N, signed by a Servicing Officer.

                  If the  Master  Servicer  at any time  seeks to  initiate  a
foreclosure  proceeding in respect of any Mortgaged  Property as authorized by
this Agreement,  the Master Servicer shall deliver or cause to be delivered to
the Trustee, for signature, as appropriate, any court pleadings,  requests for
trustee's sale or other documents  necessary to effectuate such foreclosure or
any legal  action  brought to obtain  judgment  against the  Mortgagor  on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce
any other remedies or rights  provided by the Mortgage Note or the Mortgage or
otherwise available at law or in equity.

Section 3.16.     Documents, Records and Funds in Possession of the 
                  Master Servicer to be Held for the Trustee.

                  The Master  Servicer  shall account fully to the Trustee for
any funds received by the Master  Servicer or which otherwise are collected by
the Master Servicer as Liquidation  Proceeds or Insurance  Proceeds in respect
of any Mortgage Loan.  All Mortgage  Files and funds  collected or held by, or
under the control of, the Master  Servicer in respect of any  Mortgage  Loans,
whether  from the  collection  of  principal  and  interest  payments  or from
Liquidation  Proceeds,  including  but not limited to, any funds on deposit in
the  Certificate  Account,  shall be held by the  Master  Servicer  for and on
behalf of the Trustee and shall be and remain the sole and exclusive  property
of the Trustee,  subject to the applicable  provisions of this Agreement.  The
Master  Servicer  also agrees  that it shall not create,  incur or subject any
Mortgage  File or any funds that are  deposited  in the  Certificate  Account,
Distribution  Account or any Escrow Account or Servicing Account, or any funds
that otherwise are or may become due or payable to the Trustee for the benefit
of the  Certificateholders,  to any claim, lien, security interest,  judgment,
levy,  writ of attachment or other  encumbrance,  or assert by legal action or
otherwise any claim or right of setoff  against any Mortgage File or any funds
collected on, or in connection with, a Mortgage Loan,  except,  however,  that
the Master  Servicer  shall be entitled to set off against and deduct from any
such  funds any  amounts  that are  properly  due and  payable  to the  Master
Servicer under this Agreement.

Section 3.17.     Servicing Compensation.

                  As  compensation  for its activities  hereunder,  the Master
Servicer  shall be entitled out of each payment of interest on a Mortgage Loan
(or portion thereof) included in the Trust Fund to retain or withdraw from the
Certificate  Account  an amount  equal to the  Master  Servicing  Fee for such
Distribution Date.

                  Additional  master  servicing  compensation  in the  form of
Excess Proceeds,  prepayment penalties,  assumption fees, late payment charges
and all income and gain net of any losses realized from Permitted  Investments
shall be  retained  by the Master  Servicer  to the extent not  required to be
deposited in the  Certificate  Account  pursuant to Section  3.08.  The Master
Servicer  shall be required to pay all expenses  incurred by it in  connection
with its servicing activities hereunder (including payment of any premiums for
hazard insurance and any Primary Insurance Policy and maintenance of the other
forms of  insurance  coverage  required  by this  Agreement)  and shall not be
entitled to  reimbursement  therefor except as  specifically  provided in this
Agreement.

                  As  compensation  for its  activities  under  its  Servicing
Agreement,  each  Servicer  shall be entitled to retain out of each payment of
interest on a Mortgage Loan (or portion thereof) included in the Trust Fund an
amount equal to interest at the  applicable  Servicing  Fee Rate on the Stated
Principal  Balance of the related Mortgage Loan for the period covered by such
interest payment.

                  Additional servicing  compensation in the form of prepayment
penalties,  assumption  fees and late payment charges shall be retained by the
Servicers to the extent not required to be deposited in the Servicing Accounts
pursuant to the related Servicing  Agreement.  Each Servicer shall be required
to pay all expenses incurred by it in connection with its servicing activities
under its  Servicing  Agreement  (including  payment of any premium for hazard
insurance and any Primary  Insurance Policy and maintenance of the other forms
of insurance coverage required by this Agreement and its Servicing  Agreement)
and shall not be entitled to  reimbursement  therefor  except as  specifically
provided in its Servicing Agreement and not inconsistent with this Agreement.

                  In the  event  of any  Prepayment  Interest  Shortfall,  the
aggregate  Master  Servicing Fee for such  Distribution  Date shall be reduced
(but not below zero) by an amount equal to such Prepayment Interest Shortfall.

Section 3.18.     Annual Statement as to Compliance.

                  The Master  Servicer  shall deliver to the Depositor and the
Trustee on or before 120 days  after the end of the Master  Servicer's  fiscal
year,  commencing with its 1999 fiscal year, an Officer's Certificate stating,
as to the signer  thereof,  that (i) a review of the  activities of the Master
Servicer  during the  preceding  calendar year and of the  performance  of the
Master  Servicer  under this  Agreement  has been made  under  such  officer's
supervision,  (ii) to the  best of such  officer's  knowledge,  based  on such
review,  the Master  Servicer has  fulfilled  all its  obligations  under this
Agreement  throughout  such  year,  or,  if there  has been a  default  in the
fulfillment of any such obligation, specifying each such default known to such
officer  and the  nature  and  status  thereof  and  (iii) to the best of such
officer's knowledge, each Servicer has fulfilled all its obligations under its
Servicing  Agreement  throughout such year, or, if there has been a default in
the fulfillment of any such obligation,  specifying each such default known to
such officer and the nature and status  thereof.  The Trustee  shall forward a
copy of each such statement to each Rating Agency.

Section 3.19.     Annual Independent Public Accountants' Servicing 
                  Statement; Financial Statements.

                  On or before 120 days after the end of the Master Servicer's
fiscal year,  commencing with its 1999 fiscal year, the Master Servicer at its
expense shall cause a nationally or regionally  recognized firm of independent
public  accountants  (who may also render other services to the Servicer,  the
Seller or any affiliate  thereof) which is a member of the American  Institute
of Certified Public  Accountants to furnish a statement to the Trustee and the
Depositor  to the effect that such firm has  examined  certain  documents  and
records  relating to the servicing of the Mortgage  Loans under this Agreement
or of mortgage  loans under  pooling and  servicing  agreements  substantially
similar to this Agreement (such statement to have attached  thereto a schedule
setting forth the pooling and servicing  agreements covered thereby) and that,
on the basis of such examination,  conducted  substantially in compliance with
the  Uniform  Single  Attestation  Program for  Mortgage  Bankers or the Audit
Program for  Mortgages  serviced for FNMA and FHLMC,  such  servicing has been
conducted in compliance with such pooling and servicing  agreements except for
such significant  exceptions or errors in records that, in the opinion of such
firm, the Uniform Single Attestation Program for Mortgage Bankers or the Audit
Program for Mortgages  serviced for FNMA and FHLMC  requires it to report.  In
rendering such statement, such firm may rely, as to matters relating to direct
servicing of mortgage loans by  Subservicers,  upon comparable  statements for
examinations  conducted  substantially  in compliance  with the Uniform Single
Attestation  Program for Mortgage  Bankers or the Audit  Program for Mortgages
serviced for FNMA and FHLMC  (rendered  within one year of such  statement) of
independent public accountants with respect to the related Subservicer. Copies
of such  statement  shall be provided by the Trustee to any  Certificateholder
upon request at the Master Servicer's expense, provided that such statement is
delivered by the Master Servicer to the Trustee.

Section 3.20.     Errors and Omissions Insurance; Fidelity Bonds.

                  The Master Servicer shall obtain and maintain in force,  and
shall  cause each  Servicer to obtain and  maintain in force,  (a) a policy or
policies of insurance  covering errors and omissions in the performance of its
obligations  as Master  Servicer  hereunder or as Servicer under its Servicing
Agreement,  as the case may be,  and (b) a  fidelity  bond in  respect  of its
officers,  employees and agents.  Each such policy or policies and bond shall,
together,  comply with the requirements from time to time of FNMA or FHLMC for
persons performing servicing for mortgage loans purchased by FNMA or FHLMC. In
the event  that any such  policy or bond  ceases to be in  effect,  the Master
Servicer shall obtain a comparable  replacement policy or bond from an insurer
or issuer  meeting  the  requirements  set forth  above as of the date of such
replacement.

                                  ARTICLE IV

                               DISTRIBUTIONS AND
                        ADVANCES BY THE MASTER SERVICER

Section 4.01.     Advances.

                  The Master Servicer shall determine on or before each Master
Servicer  Advance Date  whether it is required to make an Advance  pursuant to
the definition  thereof.  If the Master Servicer  determines it is required to
make an Advance,  it shall,  on or before the Master  Servicer  Advance  Date,
either (i) deposit into the Certificate Account an amount equal to the Advance
or (ii) make an appropriate  entry in its records  relating to the Certificate
Account  that any  Amount  Held for Future  Distribution  has been used by the
Master  Servicer in discharge of its obligation to make any such Advance.  Any
funds so applied  shall be replaced  by the Master  Servicer by deposit in the
Certificate  Account no later than the close of  business  on the next  Master
Servicer  Advance Date. The Master Servicer shall be entitled to be reimbursed
from the  Certificate  Account for all Advances of its own funds made pursuant
to this  Section  4.01 as provided in Section  3.11.  The  obligation  to make
Advances  with respect to any Mortgage  Loan shall  continue if such  Mortgage
Loan has been  foreclosed or otherwise  terminated  and the related  Mortgaged
Property has not been liquidated. The Master Servicer shall inform the Trustee
of the amount of the Advance to be made on each Master  Servicer  Advance Date
no later than the second Business Day before the related Distribution Date.

                  The Master  Servicer  shall  deliver  to the  Trustee on the
related Master Servicer  Advance Date an Officer's  Certificate of a Servicing
Officer indicating the amount of any proposed Advance determined by the Master
Servicer to be a Nonrecoverable Advance.

Section 4.02.     Priorities of Distribution.

                   (a) (1) With respect to the Available  Funds for Loan Group
1 and Remaining  Available Funds for Loan Group 2, on each Distribution  Date,
the Trustee shall withdraw such Available Funds from the Distribution  Account
and apply such funds to distributions on the specified Classes of Loan Group 1
Senior Certificates, in the following order and priority and, in each case, to
the extent of such funds remaining:

                        (i)  to  each   interest-bearing   Class   of   Senior
                   Certificates,  an amount allocable to interest equal to the

distributed  among such Classes,  pro rata,  on the basis of their  respective
Class  Certificate  Balances  (prior  to  making  any  distributions  on  such
Distribution  Date)  and  until the Class  Certificate  Balances  thereof  are
reduced to zero;  and (ii)  notwithstanding  the  allocation  and priority set

Loan during the calendar month preceding the month of such Distribution  Date,
the excess of one month's  interest at the related  Adjusted Net Mortgage Rate
on the Stated  Principal  Balance of such  Mortgage Loan as of the Due Date in
such month over the amount of Liquidation Proceeds applied as interest on such
Mortgage Loan with respect to such month,  (B) after the  Bankruptcy  Coverage

clause (i) of this  Section  4.02(d),  the  "related  Class  Optimal  Interest
Distribution  Amount" with respect to the Class A-1 Certificates and each Loan

Interest  Distribution  Amount  for  the  Class  A-1  Certificates  and  (y) a
fraction,  the  numerator of which is the  aggregate  of the Stated  Principal
Balances of the Mortgage  Loans in the related Loan Group and the  denominator
of which is the Pool Stated Principal Balance.

                   (e) Notwithstanding  the priority and allocation  contained
in  Section   4.02(a),   if,  with  respect  to  any  Class  of   Subordinated
Certificates,   on  any  Distribution  Date  the  sum  of  the  related  Class
Subordination  Percentages  of such Class and of all  Classes of  Subordinated
Certificates  which have a higher numerical Class  designation than such Class
(the  "Applicable  Credit  Support  Percentage")  is less  than  the  Original
Applicable  Credit  Support  Percentage  for such Class,  no  distribution  of
Principal  Prepayments  will be  made to any  such  Classes  (the  "Restricted
Classes") and the amount of such Principal Prepayments otherwise distributable
to the Restricted  Classes shall be distributed to the Classes of Subordinated
Certificates  having lower numerical Class  designations  than such Class, pro
rata, based on their respective Class Certificate  Balances  immediately prior
to such Distribution Date and shall be distributed in the sequential order set
forth in Section 4.02(a)(vi).

                   (b) The Trustee's  responsibility  for disbursing the above
information  to  the   Certificateholders  is  limited  to  the  availability,
timeliness and accuracy of the information derived from the Master Servicer.

                   (c)  Within a  reasonable  period of time  after the end of
each calendar year, the Trustee shall cause to be furnished to each Person who
at any time  during the  calendar  year was a  Certificateholder,  a statement
containing the information  set forth in clauses (a)(i),  (a)(ii) and (a)(vii)
of this Section 4.06  aggregated for such calendar year or applicable  portion
thereof during which such Person was a  Certificateholder.  Such obligation of
the  Trustee  shall be  deemed  to have  been  satisfied  to the  extent  that
substantially comparable information shall be provided by the Trustee pursuant
to any requirements of the Code as from time to time in effect.

Section 4.07.     Determination of Pass-Through Rates for COFI Certificates.

                  The  Pass-Through  Rate for each Class of COFI  Certificates
for each Interest  Accrual  Period after the initial  Interest  Accrual Period
shall be determined by the Trustee as provided below on the basis of the Index
and the applicable  formulae appearing in footnotes  corresponding to the COFI
Certificates  in  (1)  to  the  table  relating  to  the  Certificates  in the
Preliminary Statement.

                  Except as  provided  below,  with  respect to each  Interest
Accrual Period  following the initial  Interest  Accrual  Period,  the Trustee
shall not later  than two  Business  Days  following  the  publication  of the
applicable  Index  determine the  Pass-Through  Rate at which  interest  shall
accrue in respect of the COFI Certificates during the related Interest Accrual
Period.

                  Except  as  provided   below,   the  Index  to  be  used  in
determining the respective  Pass-Through Rates for the COFI Certificates for a
particular Interest Accrual Period shall be COFI for the second calendar month
preceding such Interest Accrual Period.  If at the Outside  Reference Date for
any Interest Accrual Period, COFI for the second calendar month preceding such
Interest Accrual Period has not been published, the Trustee shall use COFI for
the third calendar month preceding such Interest  Accrual Period.  If COFI for
neither the second nor third calendar  months  preceding any Interest  Accrual
Period has been published on or before the related Outside Reference Date, the
Index for such Interest Accrual Period and for all subsequent Interest Accrual
Periods shall be the National Cost of Funds Index for the third calendar month
preceding such Interest Accrual Period (or the fourth preceding calendar month
if such National Cost of Funds Index for the third  preceding  calendar  month
has not been published by such Outside  Reference Date). In the event that the
National Cost of Funds Index for neither the third nor fourth  calendar months
preceding  an  Interest  Accrual  Period has been  published  on or before the
related Outside  Reference Date, then for such Interest Accrual Period and for
each succeeding Interest Accrual Period, the Index shall be LIBOR,  determined
in the manner set forth below.

                  On each  Interest  Determination  Date  so long as the  COFI
Certificates  are outstanding and the applicable  Index therefor is LIBOR, the
Trustee shall either (i) request each  Reference Bank to inform the Trustee of
the  quotation  offered by its principal  London  office for making  one-month
United States dollar deposits in leading banks in the London interbank market,
as of 11:00 a.m. (London time) on such Interest  Determination Date or (ii) in
lieu of making any such request,  rely on such Reference Bank  quotations that
appear  at such  time on the  Reuters  Screen  LIBO  Page (as  defined  in the
International  Swap  Dealers   Association  Inc.  Code  of  Standard  Wording,
Assumptions and Provisions for Swaps, 1986 Edition), to the extent available.

                  With  respect to any Interest  Accrual  Period for which the
applicable  Index is LIBOR,  LIBOR for such  Interest  Accrual  Period will be
established  by the  Trustee on the  related  Interest  Determination  Date as
follows:

                   (a) If on  any  Interest  Determination  Date  two or  more
Reference Banks provide such offered  quotations,  LIBOR for the next Interest
Accrual  Period  shall  be the  arithmetic  mean  of such  offered  quotations
(rounding  such  arithmetic  mean upwards if  necessary  to the nearest  whole
multiple of 1/32%).

                   (b) If on any Interest  Determination Date only one or none
of the Reference  Banks provides such offered  quotations,  LIBOR for the next
Interest  Accrual  Period  shall be  whichever  is the  higher of (i) LIBOR as
determined  on the previous  Interest  Determination  Date or (ii) the Reserve
Interest Rate.  The "Reserve  Interest Rate" shall be the rate per annum which
the Trustee  determines to be either (i) the arithmetic mean (rounded  upwards
if necessary to the nearest whole  multiple of 1/32%) of the one-month  United
States dollar  lending rates that New York City banks  selected by the Trustee
are quoting,  on the relevant  Interest  Determination  Date, to the principal
London offices of at least two of the Reference Banks to which such quotations
are, in the opinion of the Trustee,  being so made,  or (ii) in the event that
the Trustee can determine no such arithmetic mean, the lowest one-month United
States dollar  lending rate which New York City banks  selected by the Trustee
are quoting on such Interest Determination Date to leading European banks.

                  From such time as the  applicable  Index becomes LIBOR until
all of the COFI  Certificates  are paid in full, the Trustee will at all times
retain at least four  Reference  Banks for the purposes of  determining  LIBOR
with  respect  to  each  interest  Determination  Date.  The  Master  Servicer
initially shall designate the Reference Banks.  Each "Reference Bank" shall be
a  leading  bank  engaged  in  transactions  in  Eurodollar  deposits  in  the
international  Eurocurrency market, shall not control, be controlled by, or be
under common control with, the Trustee and shall have an established  place of
business in London.  If any such  Reference Bank should be unwilling or unable
to act as such or if the Master Servicer  should  terminate its appointment as
Reference  Bank, the Trustee shall  promptly  appoint or cause to be appointed
another  Reference Bank. The Trustee shall have no liability or responsibility
to any Person for (i) the  selection  of any  Reference  Bank for  purposes of
determining  LIBOR or (ii) any  inability  to retain at least  four  Reference
Banks which is caused by circumstances beyond its reasonable control.

                  In determining  LIBOR and any Pass-Through Rate for the COFI
Certificates or any Reserve Interest Rate, the Trustee may  conclusively  rely
and  shall be  protected  in  relying  upon the  offered  quotations  (whether
written,  oral or on the Reuters  Screen) from the Reference  Banks or the New
York City banks as to LIBOR or the Reserve  Interest Rate, as appropriate,  in
effect  from  time to time.  The  Trustee  shall  not have  any  liability  or
responsibility to any Person for (i) the Trustee's  selection of New York City
banks for  purposes  of  determining  any  Reserve  Interest  Rate or (ii) its
inability, following a good-faith reasonable effort, to obtain such quotations
from the  Reference  Banks or the New York  City  banks or to  determine  such
arithmetic mean, all as provided for in this Section 4.07.

                  The  establishment of LIBOR and each  Pass-Through  Rate for
the COFI  Certificates by the Trustee shall (in the absence of manifest error)
be final,  conclusive  and binding upon each Holder of a  Certificate  and the
Trustee.

Section 4.08.     Determination of Pass-Through Rates for LIBOR Certificates.

                  On each  Interest  Determination  Date so long as the  LIBOR
Certificates  are  outstanding,  the Trustee  shall  either (i)  request  each
Reference Bank to inform the Trustee of the quotation offered by its principal
London office for making  one-month  United States dollar  deposits to leading
banks in the London interbank  market,  as of 11:00 a.m. (London time) on such
Interest  Determination Date or (ii) in lieu of making any such request,  rely
on such  Reference  Bank  quotations  that  appear at such time on the Reuters
Screen LIBO Page (as defined in the  International  Swap  Dealers  Association
Inc. Code of Standard  Wording,  Assumptions  and provisions  for Swaps,  1986
Edition), to the extent available.

                  LIBOR  for  the  next  Interest   Accrual   Period  will  be
established by the Trustee on each interest Determination Date as follows:

                   (a) If on  any  interest  Determination  Date  two or  more
Reference Banks provide such offered  quotations,  LIBOR for the next Interest
Accrual  Period  shall  be the  arithmetic  mean  of such  offered  quotations
(rounding  such  arithmetic  mean upwards if  necessary  to the nearest  whole
multiple of 1/32%).

                   (b) If on any Interest  Determination Date only one or none
of the Reference  Banks provides such offered  quotations,  LIBOR for the next
Interest  Accrual  Period  shall be  whichever  is the  higher of (i) LIBOR as
determined  on the previous  Interest  Determination  Date or (ii) the Reserve
Interest Rate.  The "Reserve  Interest Rate" shall be the rate per annum which
the Trustee  determines to be either (i) the arithmetic mean (rounded  upwards
if necessary to the nearest whole  multiple of 1/32%) of the one-month  United
States dollar  lending rates that New York City banks  selected by the Trustee
are quoting,  on the relevant  Interest  Determination  Date, to the principal
London offices of at least two of the Reference Banks to which such quotations
are, in the opinion of the Trustee,  being so made,  or (ii) in the event that
the Trustee can determine no such arithmetic mean, the lowest one-month United
States dollar  lending rate which New York City banks  selected by the Trustee
are quoting on such Interest Determination Date to leading European banks.

                   (c) If on any  interest  Determination  Date the trustee is
required but is unable to determine  the Reserve  Interest  Rate in the manner
provided in paragraph  (b) above,  LIBOR shall be LIBOR as  determined  on the
preceding Interest  Determination  Date, or, in the case of the first Interest
Determination Date, the Initial LIBOR Rate.

                  Until all of the LIBOR  Certificates  are paid in full,  the
Trustee will at all times retain at least four Reference Banks for the purpose
of  determining  LIBOR with respect to each Interest  Determination  Date. The
Master Servicer initially shall designate the Reference Banks. Each "Reference
Bank" shall be a leading bank engaged in transactions  in Eurodollar  deposits
in the international Eurocurrency market, shall not control, be controlled by,
or be under common  control  with,  the Trustee and shall have an  established
place of business in London. If any such Reference Bank should be unwilling or
unable  to  act as  such  or if  the  Master  Servicer  should  terminate  its
appointment as Reference Bank, the Trustee shall promptly  appoint or cause to
be appointed  another  Reference  Bank. The Trustee shall have no liability or
responsibility  to any Person for (i) the selection of any Reference  Bank for
purposes of  determining  LIBOR or (ii) any  inability to retain at least four
Reference  Banks  which is  caused  by  circumstances  beyond  its  reasonable
control.

                  The Pass-Through  Rate for each Class of LIBOR  Certificates
for each  Interest  Accrual  Period shall be determined by the Trustee on each
Interest  Determination Date so long as the LIBOR Certificates are outstanding
on the basis of LIBOR  and the  respective  formulae  appearing  in  footnotes
corresponding  to  the  LIBOR  Certificates  in  the  table  relating  to  the
Certificates in the Preliminary Statement.

                  In determining  LIBOR, any  Pass-Through  Rate for the LIBOR
Certificates or any Reserve Interest Rate, the Trustee may  conclusively  rely
and  shall be  protected  in  relying  upon the  offered  quotations  (whether
written,  oral or on the Reuters  Screen) from the Reference  Banks or the New
York City banks as to LIBOR or the Reserve  Interest Rate, as appropriate,  in
effect  from  time to time.  The  Trustee  shall  not have  any  liability  or
responsibility to any Person for (i) the Trustee's  selection of New York City
banks for  purposes  of  determining  any  Reserve  Interest  Rate or (ii) its
inability, following a good-faith reasonable effort, to obtain such quotations
from the  Reference  Banks or the New York  City  banks or to  determine  such
arithmetic mean, all as provided for in this Section 4.08.

                  The  establishment of LIBOR and each  Pass-Through  Rate for
the LIBOR Certificates by the Trustee shall (in the absence of manifest error)
be final,  conclusive  and binding upon each Holder of a  Certificate  and the
Trustee.

                               THE CERTIFICATES

Section 5.01.     The Certificates.

                  The  Certificates   shall  be  substantially  in  the  forms
attached hereto as exhibits.  The Certificates shall be issuable in registered
form,  in the minimum  denominations,  integral  multiples  in excess  thereof
(except that one Certificate in each Class may be issued in a different amount
which must be in excess of the applicable minimum  denomination) and aggregate
denominations per Class set forth in the Preliminary Statement.

                  Subject to Section 9.02 respecting the final distribution on
the   Certificates,   on  each   Distribution  Date  the  Trustee  shall  make
distributions to each Certificateholder of record on the preceding Record Date
either (x) by wire transfer in immediately  available  funds to the account of
such holder at a bank or other entity having appropriate  facilities therefor,
if (i) such Holder has so notified  the  Trustee at least five  Business  Days
prior to the  related  Record  Date  and (ii)  such  Holder  shall  hold (A) a
Notional Amount Certificate,  (B) 100% of the Class Certificate Balance of any
Class  of  Certificates  or (C)  Certificates  of  any  Class  with  aggregate
principal  Denominations of not less than $1,000,000 or (y) by check mailed by
first  class mail to such  Certificateholder  at the  address  of such  holder
appearing in the Certificate Register.

                  The  Certificates  shall be executed by manual or  facsimile
signature  on behalf of the  Trustee by an  authorized  officer.  Certificates
bearing the manual or facsimile  signatures  of  individuals  who were, at the
time such signatures were affixed, authorized to sign on behalf of the Trustee
shall bind the Trustee,  notwithstanding  that such individuals or any of them
have ceased to be so authorized prior to the  countersignature and delivery of
any  such  Certificates  or did not  hold  such  offices  at the  date of such
Certificate.  No  Certificate  shall be  entitled  to any  benefit  under this
Agreement, or be valid for any purpose, unless countersigned by the Trustee by
manual  signature,  and such  countersignature  upon any Certificate  shall be
conclusive  evidence,  and the only evidence,  that such  Certificate has been
duly executed and delivered  hereunder.  All  Certificates  shall be dated the
date of  their  countersignature.  On the  Closing  Date,  the  Trustee  shall
countersign  the  Certificates to be issued at the direction of the Depositor,
or any affiliate thereof.

                  The Depositor shall provide, or cause to be provided, to the
Trustee on a  continuous  basis,  an adequate  inventory  of  Certificates  to
facilitate transfers.

Section 5.02.     Certificate Register; Registration of Transfer 
                  and Exchange of Certificates.

                   (a) The Trustee shall  maintain,  or cause to be maintained
in accordance with the provisions of Section 5.06, a Certificate  Register for
the Trust Fund in which,  subject to the provisions of subsections (b) and (c)
below and 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.  Upon surrender for registration
of transfer of any Certificate,  the Trustee shall execute and deliver, in the
name of the designated transferee or transferees, one or more new Certificates
of the same Class and aggregate Percentage Interest.

                  At the option of a  Certificateholder,  Certificates  may be
exchanged for other Certificates of the same Class in authorized denominations
and evidencing the same  aggregate  Percentage  Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee.  Whenever
any Certificates  are so surrendered for exchange,  the Trustee shall execute,
authenticate,  and deliver the Certificates which the Certificateholder making
the  exchange  is  entitled  to  receive.   Every  Certificate   presented  or
surrendered for registration of transfer or exchange shall be accompanied by a
written  instrument  of transfer  in form  satisfactory  to the  Trustee  duly
executed by the holder thereof or his attorney duly authorized in writing.

                  No service  charge to the  Certificateholders  shall be made
for any registration of transfer or exchange of Certificates, but 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 may be required.

                  All Certificates surrendered for registration of transfer or
exchange  shall be  cancelled  and  subsequently  destroyed  by the Trustee in
accordance with the Trustee's customary procedures.

                   (b) No  transfer  of a  Private  Certificate  shall be made
unless such transfer is made pursuant to an effective  registration  statement
under the Securities Act and any applicable state securities laws or is exempt
from the  registration  requirements  under said Act and such state securities
laws. In the event that a transfer is to be made in reliance upon an exemption
from the Securities Act and such laws, in order to assure  compliance with the
Securities  Act and such laws, the  Certificateholder  desiring to effect such
transfer  and  such  Certificateholder's  prospective  transferee  shall  each
certify to the  Trustee in  writing  the facts  surrounding  the  transfer  in
substantially  the form set forth in Exhibit J (the "Transferor  Certificate")
and (i) deliver a letter in  substantially  the form of either  Exhibit K (the
"Investment Letter") or Exhibit L (the "Rule 144A Letter") or (ii) there shall
be  delivered  to the Trustee at the expense of the  transferor  an Opinion of
Counsel  that such  transfer  may be made  pursuant to an  exemption  from the
Securities  Act.  The  Depositor  shall  provide  to any  Holder  of a Private
Certificate  and any  prospective  transferee  designated  by any such Holder,
information regarding the related Certificates and the Mortgage Loans and such
other   information  as  shall  be  necessary  to  satisfy  the  condition  to
eligibility set forth in Rule 144A(d)(4) for transfer of any such  Certificate
without  registration  thereof  under  the  Securities  Act  pursuant  to  the
registration  exemption  provided  by Rule 144A.  The  Trustee  and the Master
Servicer  shall  cooperate  with the  Depositor  in  providing  the Rule  144A
information  referenced in the preceding sentence,  including providing to the
Depositor such information regarding the Certificates,  the Mortgage Loans and
other  matters  regarding  the Trust Fund as the  Depositor  shall  reasonably
request to meet its obligation under the preceding sentence.  Each Holder of a
Private  Certificate  desiring to effect such transfer shall,  and does hereby
agree to,  indemnify the Trustee and the Depositor,  the Seller and the Master
Servicer  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.

                  No transfer of an ERISA-Restricted Certificate shall be made
unless the Trustee shall have received  either (i) a  representation  from the
transferee  of  such  Certificate  acceptable  to and in  form  and  substance
satisfactory  to the  Trustee  (in the  event  such  Certificate  is a Private
Certificate or a Residual  Certificate,  such requirement is satisfied only by
the  Trustee's  receipt  of  a  representation   letter  from  the  transferee
substantially  in the form of Exhibit K or Exhibit L), to the effect that such
transferee is not an employee  benefit plan or arrangement  subject to Section
406 of ERISA or a plan  subject  to  Section  4975 of the  Code,  nor a person
acting on behalf of any such plan or  arrangement  nor using the assets of any
such plan or arrangement to effect such transfer,  or (ii) if the purchaser is
an insurance  company,  a  representation  that the  purchaser is an insurance
company  which is  purchasing  such  Certificates  with funds  contained in an
"insurance  company general  account" (as such term is defined in Section V(e)
of Prohibited  Transaction  Class Exemption 95-60 ("PTCE 95-60")) and that the
purchase  and holding of such  Certificates  are  covered  under PTCE 95-60 or
(iii) in the  case of any  such  ERISA-Restricted  Certificate  presented  for
registration  in the name of an employee  benefit plan subject to ERISA,  or a
plan or  arrangement  subject  to  Section  4975 of the  Code  (or  comparable
provisions of any subsequent enactments), or a trustee of any such plan or any
other person  acting on behalf of any such plan or  arrangement  or using such
plan's or  arrangement's  assets,  an Opinion of Counsel  satisfactory  to the
Trustee,  which  Opinion  of  Counsel  shall not be an  expense  of either the
Trustee or the Trust Fund,  addressed to the  Trustee,  to the effect that the
purchase or holding of such  ERISA-Restricted  Certificate  will not result in
the assets of the Trust Fund being  deemed to be "plan  assets" and subject to
the  prohibited  transaction  provisions  of  ERISA  and the Code and will not
subject  the  Trustee  to  any  obligation  in  addition  to  those  expressly
undertaken  in  this  Agreement  or to  any  liability.  For  purposes  of the
preceding sentence,  with respect to an  ERISA-Restricted  Certificate that is
not a  Private  Certificate  or a  Residual  Certificate,  in  the  event  the
representation  letter referred to in the preceding sentence is not furnished,
such  representation  shall be deemed to have been made to the  Trustee by the
transferee's   (including   an   initial   acquiror's)   acceptance   of   the
ERISA-Restricted  Certificates.  Notwithstanding anything else to the contrary
herein,  any purported  transfer of an  ERISA-Restricted  Certificate to or on
behalf of an employee benefit plan subject to ERISA or to the Code without the
delivery to the Trustee of an Opinion of Counsel  satisfactory  to the Trustee
as described above shall be void and of no effect.

                  To the extent permitted under applicable law (including, but
not limited to, ERISA),  the Trustee shall be under no liability to any Person
for any registration of transfer of any  ERISA-Restricted  Certificate that is
in fact not  permitted by this Section  5.02(b) or for making any payments due
on such  Certificate  to the Holder  thereof or taking any other  action  with
respect to such Holder under the  provisions of this  Agreement so long as the
transfer  was  registered  by the  Trustee in  accordance  with the  foregoing
requirements.

                   (c)  Each  Person  who has or who  acquires  any  Ownership
Interest  in a  Residual  Certificate  shall be  deemed by the  acceptance  or
acquisition  of such  Ownership  Interest  to have  agreed  to be bound by the
following  provisions,  and the rights of each Person  acquiring any Ownership
Interest in a Residual  Certificate  are  expressly  subject to the  following
provisions:

                        (i) Each Person  holding or  acquiring  any  Ownership
                   Interest  in a Residual  Certificate  shall be a  Permitted
                   Transferee  and shall  promptly  notify the  Trustee of any
                   change or  impending  change in its  status as a  Permitted
                   Transferee.

                        (ii) No Ownership  Interest in a Residual  Certificate
                   may  be  registered  on  the  Closing  Date  or  thereafter
                   transferred,   and  the  Trustee  shall  not  register  the
                   Transfer of any Residual Certificate unless, in addition to
                   the  certificates  required to be  delivered to the Trustee
                   under  subparagraph  (b) above, the Trustee shall have been
                   furnished with an affidavit (a "Transfer Affidavit") of the
                   initial  owner  or the  proposed  transferee  in  the  form
                   attached hereto as Exhibit I.

                        (iii) Each Person  holding or acquiring  any Ownership
                   Interest  in a  Residual  Certificate  shall  agree  (A) to
                   obtain a Transfer  Affidavit  from any other Person to whom
                   such Person attempts to Transfer its Ownership  Interest in
                   a Residual Certificate,  (B) to obtain a Transfer Affidavit
                   from any Person for whom such  Person is acting as nominee,
                   trustee  or agent in  connection  with  any  Transfer  of a
                   Residual  Certificate and (C) not to Transfer its Ownership
                   Interest in a Residual Certificate or to cause the Transfer
                   of an Ownership  Interest in a Residual  Certificate to any
                   other Person if it has actual knowledge that such Person is
                   not a Permitted Transferee.

                        (iv)  Any  attempted  or  purported  Transfer  of  any
                   Ownership  Interest in a Residual  Certificate in violation
                   of  the  provisions  of  this  Section   5.02(c)  shall  be
                   absolutely  null and void and  shall  vest no rights in the
                   purported  Transferee.  If any purported  transferee  shall
                   become a Holder of a Residual  Certificate  in violation of
                   the  provisions  of this  Section  5.02(c),  then  the last
                   preceding  Permitted  Transferee  shall be  restored to all
                   rights  as  Holder  thereof  retroactive  to  the  date  of
                   registration of Transfer of such Residual Certificate.  The
                   Trustee  shall be under no  liability to any Person for any
                   registration of Transfer of a Residual  Certificate that is
                   in fact not  permitted by Section  5.02(b) and this Section
                   5.02(c) or for making any payments due on such  Certificate
                   to the  Holder  thereof  or taking  any other  action  with
                   respect  to  such  Holder  under  the  provisions  of  this
                   Agreement  so long as the  Transfer  was  registered  after
                   receipt  of  the  related  Transfer  Affidavit,  Transferor
                   Certificate   and  either  the  Rule  144A  Letter  or  the
                   Investment  Letter.  The Trustee  shall be entitled but not
                   obligated   to  recover  from  any  Holder  of  a  Residual
                   Certificate that was in fact not a Permitted  Transferee at
                   the time it became a Holder or, at such  subsequent time as
                   it became other than a Permitted  Transferee,  all payments
                   made on such Residual  Certificate at and after either such
                   time.  Any such  payments so recovered by the Trustee shall
                   be paid and delivered by the Trustee to the last  preceding
                   Permitted Transferee of such Certificate.

                        (v) The  Depositor  shall use its best efforts to make
                   available,   upon  receipt  of  written  request  from  the
                   Trustee,  all  information  necessary  to  compute  any tax
                   imposed under Section  860E(e) of the Code as a result of a
                   Transfer of an Ownership Interest in a Residual Certificate
                   to any Holder who is not a Permitted Transferee.

                  The restrictions on Transfers of a Residual  Certificate set
forth  in this  Section  5.02(c)  shall  cease to  apply  (and the  applicable
portions of the legend on a Residual  Certificate may be deleted) with respect
to Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which  Opinion of  Counsel  shall not be an  expense  of the Trust  Fund,  the
Trustee, the Seller or the Master Servicer, to the effect that the elimination
of such  restrictions will not cause the REMIC hereunder to fail to qualify as
a REMIC at any time that the  Certificates  are  outstanding  or result in the
imposition  of any tax on the  Trust  Fund,  a  Certificateholder  or  another
Person.  Each Person holding or acquiring any Ownership Interest in a Residual
Certificate hereby consents to any amendment of this Agreement which, based on
an Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Residual
Certificate is not  transferred,  directly or indirectly,  to a Person that is
not a  Permitted  Transferee  and (b) to  provide  for a means to  compel  the
Transfer  of a Residual  Certificate  which is held by a Person  that is not a
Permitted Transferee to a Holder that is a Permitted Transferee.

                   (d) The  preparation and delivery of all  certificates  and
opinions  referred to above in this Section 5.02 in  connection  with transfer
shall be at the expense of the parties to such transfers.

                   (e) Except as provided below,  the Book-Entry  Certificates
shall at all times  remain  registered  in the name of the  Depository  or its
nominee and at all times:  (i)  registration  of the  Certificates  may not be
transferred by the Trustee except to another  Depository;  (ii) the Depository
shall maintain  book-entry  records with respect to the Certificate Owners and
with respect to ownership and transfers of such Book-Entry Certificates; (iii)
ownership and transfers of registration of the Book-Entry  Certificates on the
books of the Depository shall be governed by applicable  rules  established by
the Depository;  (iv) the Depository may collect its usual and customary fees,
charges and expenses from its Depository  Participants;  (v) the Trustee shall
deal with the Depository,  Depository  Participants and indirect participating
firms  as   representatives  of  the  Certificate  Owners  of  the  Book-Entry
Certificates  for  purposes  of  exercising  the rights of holders  under this
Agreement,  and requests and directions for and votes of such  representatives
shall not be  deemed  to be  inconsistent  if they are made  with  respect  to
different Certificate Owners; and (vi) the Trustee may rely and shall be fully
protected in relying upon information furnished by the Depository with respect
to its Depository  Participants  and furnished by the Depository  Participants
with respect to indirect participating firms and persons shown on the books of
such indirect participating firms as direct or indirect Certificate Owners.

                  All   transfers   by   Certificate   Owners  of   Book-Entry
Certificates  shall be made in accordance  with the procedures  established by
the Depository  Participant or brokerage firm  representing  such  Certificate
Owner. Each Depository Participant shall only transfer Book-Entry Certificates
of Certificate Owners it represents or of brokerage firms for which it acts as
agent in accordance with the Depository's normal procedures.

                  If (x) (i)  the  Depository  or the  Depositor  advises  the
Trustee  in  writing  that the  Depository  is no  longer  willing  or able to
properly discharge its responsibilities as Depository, and (ii) the Trustee or
the Depositor is unable to locate a qualified successor,  (y) the Depositor at
its option  advises the  Trustee in writing  that it elects to  terminate  the
book-entry  system  through the  Depository or (z) after the  occurrence of an
Event  of  Default,  Certificate  Owners  representing  at  least  51%  of the
Certificate Balance of the Book-Entry Certificates together advise the Trustee
and the  Depository  through the Depository  Participants  in writing that the
continuation of a book-entry system through the Depository is no longer in the
best  interests  of the  Certificate  Owners,  the  Trustee  shall  notify all
Certificate  Owners,  through the  Depository,  of the  occurrence of any such
event and of the  availability  of definitive,  fully-registered  Certificates
(the "Definitive  Certificates")  to Certificate  Owners  requesting the same.
Upon  surrender  to the Trustee of the related  Class of  Certificates  by the
Depository,   accompanied  by  the   instructions   from  the  Depository  for
registration, the Trustee shall issue the Definitive Certificates. Neither the
Master  Servicer,  the Depositor nor the Trustee shall be liable for any delay
in delivery of such instruction and each may  conclusively  rely on, and shall
be  protected  in relying on, such  instructions.  The Master  Servicer  shall
provide the Trustee with an adequate  inventory of  certificates to facilitate
the  issuance and transfer of  Definitive  Certificates.  Upon the issuance of
Definitive  Certificates all references herein to obligations  imposed upon or
to be  performed  by the  Depository  shall be deemed to be  imposed  upon and
performed  by the  Trustee,  to the  extent  applicable  with  respect to such
Definitive  Certificates  and the Trustee  shall  recognize the Holders of the
Definitive  Certificates as  Certificateholders  hereunder;  provided that the
Trustee  shall not by  virtue of its  assumption  of such  obligations  become
liable to any party for any act or failure to act of the Depository.

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

                  If (a)  any  mutilated  Certificate  is  surrendered  to the
Trustee,  or  the  Trustee  receives  evidence  to  its  satisfaction  of  the
destruction,  loss or theft of any  Certificate  and (b) there is delivered to
the Master  Servicer  and the Trustee  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  that  such  Certificate  has  been  acquired  by a bona  fide
purchaser, the Trustee shall execute, countersign and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like Class, tenor and Percentage  Interest.  In connection with
the issuance of any new  Certificate  under this Section 5.03, the Trustee 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  expenses
(including  the fees and expenses of the  Trustee)  connected  therewith.  Any
replacement  Certificate issued pursuant to this Section 5.03 shall constitute
complete and  indefeasible  evidence of ownership,  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.

                  The Master Servicer, the Trustee and any agent of the Master
Servicer or the Trustee may treat the Person in whose name any  Certificate is
registered  as the owner of such  Certificate  for the  purpose  of  receiving
distributions  as  provided  in this  Agreement  and for  all  other  purposes
whatsoever,  and neither the Master Servicer, the Trustee nor any agent of the
Master  Servicer  or the  Trustee  shall  be  affected  by any  notice  to the
contrary.

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

                  If  three  or  more   Certificateholders  (a)  request  such
information   in   writing   from   the   Trustee,   (b)   state   that   such
Certificateholders  desire to communicate with other  Certificateholders  with
respect to their rights under this  Agreement or under the  Certificates,  and
(c) provide a copy of the communication which such Certificateholders  propose
to  transmit,  or if the  Depositor  or Master  Servicer  shall  request  such
information in writing from the Trustee,  then the Trustee  shall,  within ten
Business Days after the receipt of such request,  provide the  Depositor,  the
Master Servicer or such  Certificateholders  at such  recipients'  expense the
most  recent  list of the  Certificateholders  of such  Trust Fund held by the
Trustee, if any. The Depositor and every  Certificateholder,  by receiving and
holding a Certificate, agree that the Trustee shall not be held accountable by
reason  of the  disclosure  of any  such  information  as to the  list  of the
Certificateholders  hereunder,  regardless  of  the  source  from  which  such
information was derived.

Section 5.06.     Maintenance of Office or Agency.

                  The Trustee will  maintain or cause to be  maintained at its
expense  an office or  offices  or agency or  agencies  in New York City where
Certificates may be surrendered for registration of transfer or exchange.  The
Trustee initially designates its Corporate Trust Office for such purposes. The
Trustee  will give  prompt  written  notice to the  Certificateholders  of any
change in such location of any such office or agency.

                     THE DEPOSITOR AND THE MASTER SERVICER

                  Section 6.01.  Respective Liabilities of the Depositor and 
the Master Servicer.

                  The Depositor and the Master  Servicer  shall each be liable
in accordance herewith only to the extent of the obligations  specifically and
respectively imposed upon and undertaken by them herein.

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

                  The Depositor and the Master Servicer will each keep in full
effect its existence, rights and franchises as a corporation under the laws of
the United States or under the laws of one of the states thereof and will each
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,  or any of the
Mortgage Loans and to perform its respective duties under this Agreement.

                  Any Person into which the  Depositor or the Master  Servicer
may be merged or  consolidated,  or any  Person  resulting  from any merger or
consolidation  to which the Depositor or the Master Servicer shall be a party,
or any  person  succeeding  to the  business  of the  Depositor  or the Master
Servicer,  shall be the successor of the Depositor or the Master Servicer,  as
the case may be,  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  the  successor  or
surviving  Person to the Master  Servicer  shall be qualified to sell mortgage
loans to, and to service mortgage loans on behalf of, FNMA or FHLMC.

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

                  None of the Depositor,  the Seller,  the Master  Servicer or
any of the  directors,  officers,  employees or agents of the  Depositor,  the
Seller  or  the  Master   Servicer   shall  be  under  any  liability  to  the
Certificateholders  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  the
Depositor,  the Seller,  the Master  Servicer  or any such Person  against any
breach of  representations  or  warranties  made by it herein or  protect  the
Depositor,  the  Seller,  the  Master  Servicer  or any such  Person  from any
liability which would otherwise be imposed by reasons 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 Depositor,  the
Seller,  the Master Servicer and any director,  officer,  employee or agent of
the Depositor, the Seller or the Master Servicer may rely in good faith on any
document of any kind prima facie properly executed and submitted by any Person
respecting  any matters  arising  hereunder.  The Depositor,  the Seller,  the
Master Servicer and any director, officer, employee or agent of the Depositor,
the Seller or the Master  Servicer  shall be indemnified by the Trust Fund and
held harmless  against any loss,  liability or expense  incurred in connection
with any audit,  controversy or judicial proceeding relating to a governmental
taxing  authority  or any  legal  action  relating  to this  Agreement  or the
Certificates,  other  than any  loss,  liability  or  expense  related  to any
specific  Mortgage Loan or Mortgage Loans (except as any such loss,  liability
or expense shall be otherwise reimbursable pursuant to this Agreement) and any
loss,  liability  or expense  incurred by reason of willful  misfeasance,  bad
faith or gross  negligence in the performance of duties hereunder or by reason
of  reckless  disregard  of  obligations  and  duties  hereunder.  None of the
Depositor,  the Seller or the Master Servicer shall be under any obligation to
appear in,  prosecute or defend any legal action that is not incidental to its
respective  duties  hereunder  and which in its  opinion may involve it in any
expense or liability; provided, however, that any of the Depositor, the Seller
or the Master Servicer may in its discretion undertake any such action that it
may deem  necessary or desirable in respect of this  Agreement  and the rights
and  duties  of the  parties  hereto  and  interests  of the  Trustee  and the
Certificateholders  hereunder.  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 Fund,  and the  Depositor,  the Seller and the Master
Servicer  shall be entitled to be reimbursed  therefor out of the  Certificate
Account.

Section 6.04.     Limitation on Resignation of the Master Servicer.

                  The Master  Servicer  shall not resign from the  obligations
and duties  hereby  imposed on it except (a) upon  appointment  of a successor
servicer  and receipt by the Trustee of a letter from each Rating  Agency that
such a resignation  and  appointment  will not result in a downgrading  of the
rating of any of the Certificates,  or (b) upon  determination that its duties
hereunder  are  no  longer   permissible   under   applicable  law.  Any  such
determination  under  clause  (b)  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  master  servicer  shall have  assumed  the Master  Servicer's
responsibilities, duties, liabilities and obligations hereunder.

                                    DEFAULT

Section 7.01.     Events of Default.

                   "Event of Default," wherever used herein,  means any one of
the following events:

                        (i) any  failure by the Master  Servicer to deposit in
                   the Certificate Account or remit to the Trustee any payment
                   required  to be made  under  the  terms of this  Agreement,
                   which failure shall continue unremedied for five days after
                   the date upon which  written  notice of such failure  shall
                   have been given to the Master  Servicer  by the  Trustee or
                   the Depositor or to the Master  Servicer and the Trustee by
                   the Holders of Certificates having not less than 25% of the
                   Voting Rights evidenced by the Certificates; or

                        (ii) any failure by the Master  Servicer to observe or
                   perform in any material  respect any other of the covenants
                   or agreements on the part of the Master Servicer  contained
                   in this  Agreement  that  materially  affects the rights of
                   Certificateholders, which failure shall continue unremedied
                   for a period  of 60 days  after  the date on which  written
                   notice of such failure  shall have been given to the Master
                   Servicer by the Trustee or the Depositor,  or to the Master
                   Servicer  and the  Trustee by the  Holders of  Certificates
                   evidencing not less than 25% of the Voting Rights evidenced
                   by the 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 receiver  or  liquidator  in any
                   insolvency, readjustment of debt, marshalling 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  or  unstayed  for a
                   period of 60 consecutive days; or

                        (iv)  the  Master   Servicer   shall  consent  to  the
                   appointment of a receiver or liquidator in any  insolvency,
                   readjustment of debt, marshalling of assets and liabilities
                   or  similar  proceedings  of  or  relating  to  the  Master
                   Servicer or all or substantially all of the property of the
                   Master Servicer; 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,  or  commence  a
                   voluntary  case  under,   any   applicable   insolvency  or
                   reorganization  statute, make an assignment for the benefit
                   of its  creditors,  or voluntarily  suspend  payment of its
                   obligations.

                  If an Event of Default  described  in clauses  (i) to (v) of
this Section 7.01 shall occur,  then, and in each and every such case, so long
as such Event of Default shall not have been remedied,  the Trustee may, or at
the direction of the Holders of Certificates  evidencing not less than 66K% of
the Voting Rights evidenced by the  Certificates,  the Trustee shall by notice
in  writing  to the  Master  Servicer  (with a copy to  each  Rating  Agency),
terminate all of the rights and  obligations of the Master Servicer under this
Agreement  and in and to the Mortgage  Loans and the proceeds  thereof,  other
than its rights as a Certificateholder  hereunder. On and after the receipt by
the Master  Servicer of such written  notice,  all  authority and power of the
Master  Servicer  hereunder,  whether with  respect to the  Mortgage  Loans or
otherwise,  shall pass to and be vested in the Trustee. The Trustee shall make
any Advance which the Master  Servicer failed to make subject to Section 3.04,
whether or not the  obligations  of the Master  Servicer have been  terminated
pursuant to this Section.  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.   Unless  expressly  provided  in  such  written  notice,  no  such
termination  shall affect any obligation of the Master Servicer to pay amounts
owed pursuant to Article VIII.  The Master  Servicer  agrees to cooperate with
the  Trustee  in  effecting   the   termination   of  the  Master   Servicer's
responsibilities  and rights hereunder,  including,  without  limitation,  the
transfer  to the  Trustee  of all  cash  amounts  which  shall  at the time be
credited to the Certificate Account, or thereafter be received with respect to
the Mortgage Loans.

                  Notwithstanding  any  termination  of the  activities of the
Master Servicer  hereunder,  the Master Servicer shall be entitled to receive,
out of any late collection of a Scheduled Payment on a Mortgage Loan which was
due  prior  to the  notice  terminating  such  Master  Servicer's  rights  and
obligations as Master Servicer hereunder and received after such notice,  that
portion  thereof  to which  such  Master  Servicer  would  have been  entitled
pursuant to Sections  3.11(a)(i) through (viii), and any other amounts payable
to such Master Servicer  hereunder the entitlement to which arose prior to the
termination of its activities hereunder.

Section 7.02.     Trustee to Act; Appointment of Successor. 

                  On and after the time the Master Servicer  receives a notice
of termination  pursuant to Section 7.01, the Trustee shall, subject to and to
the extent  provided in Section 3.07, be the successor to the Master  Servicer
in its capacity as master  servicer under this Agreement and the  transactions
set  forth  or   provided   for  herein  and  shall  be  subject  to  all  the
responsibilities, duties and liabilities relating thereto placed on the Master
Servicer by the terms and  provisions  hereof and applicable law including the
obligation  to  make  Advances  pursuant  to  Section  4.01.  As  compensation
therefor,  the Trustee shall be entitled to all funds relating to the Mortgage
Loans  that the Master  Servicer  would  have been  entitled  to charge to the
Certificate  Account  or  Distribution  Account  if the  Master  Servicer  had
continued to act hereunder.  Notwithstanding the foregoing, if the Trustee has
become the successor to the Master  Servicer in accordance  with Section 7.01,
the  Trustee  may,  if it shall be  unwilling  to so act,  or shall,  if it is
prohibited by applicable law from making Advances  pursuant to Section 4.01 or
if it is otherwise unable to so act, appoint, or petition a court of competent
jurisdiction to appoint, any established  mortgage loan servicing  institution
the appointment of which does not adversely  affect the then current rating of
the  Certificates  by each  Rating  Agency,  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. Any
successor to the Master  Servicer shall be an institution  which is a FNMA and
FHLMC approved  seller/servicer in good standing,  which has a net worth of at
least  $15,000,000,  which is willing to service the Mortgage  Loans and which
executes and delivers to the Depositor and the Trustee an agreement  accepting
such delegation and assignment, containing an assumption by such Person of the
rights, powers, duties,  responsibilities,  obligations and liabilities of the
Master Servicer  (other than  liabilities of the Master Servicer under Section
6.03 incurred prior to termination of the Master Servicer under Section 7.01),
with like effect as if originally named as a party to this Agreement; provided
that each Rating Agency  acknowledges  that its rating of the  Certificates in
effect  immediately  prior  to such  assignment  and  delegation  will  not be
qualified or reduced as a result of such  assignment and  delegation.  Pending
appointment  of a successor  to the Master  Servicer  hereunder,  the Trustee,
unless the  Trustee is  prohibited  by law from so acting,  shall,  subject to
Section 3.07, act in such capacity as hereinabove provided. In connection with
such  appointment and assumption,  the Trustee may make such  arrangements for
the compensation of such successor out of payments on Mortgage Loans as it and
such successor shall agree; provided, however, that no such compensation shall
be in excess  of the  Master  Servicing  Fee  permitted  the  Master  Servicer
hereunder.  The Trustee and such successor shall take such action,  consistent
with this Agreement,  as shall be necessary to effectuate any such succession.
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 or any failure to
perform, or any delay in performing, any duties or responsibilities hereunder,
in either  case  caused by the  failure of the Master  Servicer  to deliver or
provide,  or any delay in  delivering  or  providing,  any cash,  information,
documents or records to it.

                  Any  successor  to the Master  Servicer  as master  servicer
shall give notice to the  Mortgagors  of such  change of  servicer  and shall,
during  the term of its  service  as master  servicer,  maintain  in force the
policy or policies that the Master  Servicer is required to maintain  pursuant
to Section 6.05.

Section 7.03.     Notification to Certificateholders.

                   (a) Upon any  termination  of or appointment of a successor
to the Master  Servicer,  the Trustee shall give prompt written notice thereof
to Certificateholders and to each Rating Agency.

                   (b)  Within 60 days  after the  occurrence  of any Event of
Default, the Trustee shall transmit by mail to all  Certificateholders  notice
of each such Event of Default  hereunder  known to the  Trustee,  unless  such
Event of Default shall have been cured or waived.

                                 ARTICLE VIII

                            CONCERNING THE TRUSTEE

Section 8.01.     Duties of the Trustee.

                  The Trustee,  prior to the occurrence of an Event of Default
and after the curing of all Events of Default  that may have  occurred,  shall
undertake to perform such duties and only such duties as are  specifically set
forth in this Agreement.  In case an Event of Default has occurred and remains
uncured, the Trustee shall exercise such of the rights and powers vested in it
by this Agreement, and use the same degree of care and skill in their exercise
as a prudent  person  would  exercise  or use under the  circumstances  in the
conduct of such person's own affairs.

                  The Trustee, upon receipt of all resolutions,  certificates,
statements,   opinions,   reports,  documents,  orders  or  other  instruments
furnished  to the  Trustee  that 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
such resolution,  certificate,  statement, opinion, report, document, order or
other instrument.

                  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)  unless an Event of Default  known to the  Trustee
                   shall  have  occurred  and be  continuing,  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 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 which it believed in good faith to be genuine and
                   to  have  been  duly  executed  by the  proper  authorities
                   respecting any matters arising hereunder;

                        (ii) the  Trustee  shall not be liable for an error of
                   judgment  made in good  faith by a  Responsible  Officer or
                   Responsible  Officers  of the  Trustee,  unless it shall be
                   finally   proven  that  the  Trustee   was   negligent   in
                   ascertaining the pertinent facts; and

                        (iii) the Trustee  shall not be 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  evidencing  not less  than 25% of the  Voting
                   Rights of  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.

Section 8.02.     Certain Matters Affecting the Trustee.

                  Except as otherwise provided in Section 8.01:

                        (i) the Trustee may request and rely upon and shall be
                   protected  in acting or  refraining  from  acting  upon any
                   resolution, Officers' Certificate,  certificate of auditors
                   or any other certificate,  statement,  instrument, opinion,
                   report, notice, request, consent, order, appraisal, bond or
                   other paper or document believed by it to be genuine and to
                   have  been  signed  or  presented  by the  proper  party or
                   parties and the  Trustee  shall have no  responsibility  to
                   ascertain or confirm the  genuineness  of any  signature of
                   any such party or parties;

                        (ii) the Trustee may consult with  counsel,  financial
                   advisers or accountants and the advice of any such counsel,
                   financial  advisers  or  accountants  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 liable for any action
                   taken, suffered or omitted by it in good faith and believed
                   by it to be authorized  or within the  discretion or rights
                   or powers conferred upon it by this Agreement;

                        (iv)  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, approval, bond or
                   other paper or document,  unless requested in writing so to
                   do by Holders of Certificates  evidencing not less than 25%
                   of  the   Voting   Rights   allocated   to  each  Class  of
                   Certificates;

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

                        (vi) the  Trustee  shall  not be  required  to risk or
                   expend  its own  funds or  otherwise  incur  any  financial
                   liability in the performance of any of its duties or in the
                   exercise  of any of its  rights or powers  hereunder  if it
                   shall have reasonable  grounds for believing that repayment
                   of such funds or adequate  indemnity  against  such risk or
                   liability is not assured to it;

                        (vii) the Trustee  shall not be liable for any loss on
                   any investment of funds  pursuant to this Agreement  (other
                   than as issuer of the investment security);

                        (viii)  the  Trustee  shall  not  be  deemed  to  have
                   knowledge  of an  Event  of  Default  until  a  Responsible
                   Officer of the Trustee shall have received  written  notice
                   thereof; and

                        (ix) the  Trustee  shall be  under  no  obligation  to
                   exercise any of the trusts,  rights or powers  vested in it
                   by this  Agreement or to  institute,  conduct or defend any
                   litigation  hereunder or in relation hereto at the request,
                   order  or  direction  of  any  of  the  Certificateholders,
                   pursuant to the provisions of this  Agreement,  unless such
                   Certificateholders   shall  have  offered  to  the  Trustee
                   reasonable  security  or  indemnity   satisfactory  to  the
                   Trustee against the costs,  expenses and liabilities  which
                   may be incurred therein or thereby.

Section 8.03.     Trustee Not Liable for Certificates or Mortgage Loans.

                  The recitals  contained herein and in the Certificates shall
be taken as the statements of the Depositor or the Seller, as the case may be,
and the Trustee assumes no responsibility for their  correctness.  The Trustee
makes no  representations  as to the validity or sufficiency of this Agreement
or of the  Certificates or of any Mortgage Loan or related document other than
with  respect  to  the  Trustee's   execution  and   countersignature  of  the
Certificates.  The Trustee shall not be accountable for the use or application
by the Depositor or the Master  Servicer of any funds paid to the Depositor or
the Master  Servicer  in  respect of the  Mortgage  Loans or  deposited  in or
withdrawn  from  the  Certificate  Account  by the  Depositor  or  the  Master
Servicer.

Section 8.04.     Trustee May Own Certificates.

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

Section 8.05.     Trustee's Fees and Expenses.

                  The Trustee,  as compensation for its activities  hereunder,
shall  be  entitled  to  withdraw  from  the  Distribution   Account  on  each
Distribution  Date an amount  equal to the Trustee  Fee for such  Distribution
Date. The Trustee and any director,  officer, employee or agent of the Trustee
shall be  indemnified  by the Master  Servicer and held  harmless  against any
loss, liability or expense (including reasonable attorney's fees) (i) incurred
in connection  with any claim or legal action  relating to (a) this Agreement,
(b) the  Certificates,  or (c) the performance of any of the Trustee's  duties
hereunder,  other than any loss,  liability  or expense  incurred by reason of
willful misfeasance,  bad faith or negligence in the performance of any of the
Trustee's  duties hereunder or incurred by reason of any action of the Trustee
taken at the direction of the  Certificateholders  and (ii) resulting from any
error in any tax or information  return prepared by the Master Servicer.  Such
indemnity  shall survive the  termination of this Agreement or the resignation
or removal of the Trustee  hereunder.  Without  limiting  the  foregoing,  the
Master  Servicer  covenants  and agrees,  except as  otherwise  agreed upon in
writing by the  Depositor  and the Trustee,  and except for any such  expense,
disbursement or advance as may arise from the Trustee's negligence,  bad faith
or willful  misconduct,  to pay or reimburse the Trustee,  for all  reasonable
expenses,  disbursements  and  advances  incurred  or made by the  Trustee  in
accordance  with any of the  provisions of this  Agreement with respect to (A)
the reasonable  compensation and the expenses and disbursements of its counsel
not associated with the closing of the issuance of the  Certificates,  (B) the
reasonable  compensation,   expenses  and  disbursements  of  any  accountant,
engineer or appraiser  that is not regularly  employed by the Trustee,  to the
extent that the Trustee  must engage such  persons to perform acts or services
hereunder and (C) printing and engraving expenses in connection with preparing
any Definitive Certificates.  Except as otherwise provided herein, the Trustee
shall not be entitled  to payment or  reimbursement  for any  routine  ongoing
expenses  incurred  by the  Trustee  in the  ordinary  course of its duties as
Trustee,  Registrar,  Tax Matters Person or Paying Agent  hereunder or for any
other expenses.

Section 8.06.     Eligibility Requirements for the Trustee.

                  The Trustee hereunder shall at all times be a corporation or
association  organized  and  doing  business  under the laws of a 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,
subject to supervision or examination by federal or state authority and with a
credit  rating which would not cause  either of the Rating  Agencies to reduce
their  respective then current ratings of the Certificates (or having 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  8.06 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 8.06,  the Trustee shall resign  immediately in the
manner and with the effect  specified in Section 8.07.  The entity  serving as
Trustee may have normal banking and trust relationships with the Depositor and
its affiliates or the Master Servicer and its affiliates;  provided,  however,
that such entity  cannot be an affiliate of the Seller,  the  Depositor or the
Master  Servicer other than the Trustee in its role as successor to the Master
Servicer.

Section 8.07.     Resignation and Removal of the Trustee.

                  The Trustee may at any time  resign and be  discharged  from
the trusts  hereby  created by giving  written  notice of  resignation  to the
Depositor,  the Master  Servicer and each Rating  Agency not less than 60 days
before the date specified in such notice,  when, subject to Section 8.08, such
resignation  is to take  effect,  and  acceptance  by a  successor  trustee in
accordance with Section 8.08 meeting the  qualifications  set forth in Section
8.06. If no successor trustee meeting such  qualifications  shall have been so
appointed  and have  accepted  appointment  within 30 days after the giving of
such notice or  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 8.06 and shall fail to resign after
written request thereto by the Depositor,  or if at any time the Trustee shall
become incapable of acting, or shall be adjudged as bankrupt or insolvent,  or
a receiver of the Trustee or of its property shall be appointed, or any public
officer  shall take  charge or control of the  Trustee or of its  property  or
affairs for the purpose of rehabilitation,  conservation or liquidation,  or a
tax is  imposed  with  respect  to the  Trust  Fund by any  state in which the
Trustee or the Trust Fund is located and the  imposition  of such tax would be
avoided by the appointment of a different  trustee,  then the Depositor or the
Master  Servicer  may remove the Trustee  and  appoint a successor  trustee by
written instrument, in triplicate, one copy of which shall be delivered to the
Trustee,  one  copy  to the  Master  Servicer  and one  copy to the  successor
trustee.

                  The Holders of Certificates  entitled to at least 51% of the
Voting  Rights may at any time  remove the  Trustee  and  appoint a  successor
trustee by written  instrument or instruments,  in triplicate,  signed by such
Holders or their attorneys-in-fact duly authorized,  one complete set of which
shall be  delivered  by the  successor  Trustee  to the Master  Servicer,  one
complete set to the Trustee so removed and one  complete set to the  successor
so  appointed.  Notice of any  removal of the  Trustee  shall be given to each
Rating Agency by the successor trustee.

                  Any resignation or removal of the Trustee and appointment of
a successor  trustee  pursuant to any of the  provisions  of this Section 8.07
shall become effective upon acceptance of appointment by the successor trustee
as provided in Section 8.08.

Section 8.08.     Successor Trustee.

                  Any successor  trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the Depositor and to its predecessor
trustee  and the Master  Servicer an  instrument  accepting  such  appointment
hereunder and thereupon the resignation or removal of the predecessor  trustee
shall become  effective and such successor  trustee,  without any further act,
deed or  conveyance,  shall become  fully vested with all the rights,  powers,
duties and obligations of its predecessor  hereunder,  with the like effect as
if originally named as trustee herein. The Depositor,  the Master Servicer and
the predecessor trustee 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 trustee shall accept appointment as provided in
this Section 8.08 unless at the time of such acceptance such successor trustee
shall be eligible  under the  provisions  of Section 8.06 and its  appointment
shall not adversely affect the then current rating of the Certificates.

                  Upon  acceptance of  appointment  by a successor  trustee as
provided  in this  Section  8.08,  the  Depositor  shall  mail  notice  of the
succession of such trustee  hereunder to all Holders of  Certificates.  If the
Depositor  fails to mail  such  notice  within  10 days  after  acceptance  of
appointment by the successor  trustee,  the successor trustee shall cause such
notice to be mailed at the expense of the Depositor.

Section 8.09.     Merger or Consolidation of the Trustee.

                  Any  corporation  into  which the  Trustee  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 Trustee shall be a
party, or any corporation  succeeding to the business of the Trustee, shall be
the successor of the Trustee  hereunder,  provided that such corporation shall
be eligible  under the  provisions  of Section 8.06  without the  execution or
filing of any paper or further act on the part of any of the  parties  hereto,
anything herein to the contrary notwithstanding.

Section 8.10.     Appointment of Co-Trustee or Separate Trustee.

                  Notwithstanding  any other provisions of this Agreement,  at
any  time,  for  the  purpose  of  meeting  any  legal   requirements  of  any
jurisdiction  in which any part of the Trust  Fund or  property  securing  any
Mortgage Note may at the time be located,  the Master Servicer and the Trustee
acting  jointly  shall  have the power  and  shall  execute  and  deliver  all
instruments  to appoint one or more Persons  approved by the Trustee to act as
co-trustee or  co-trustees  jointly with the Trustee,  or separate  trustee or
separate  trustees,  of all or any part of the Trust Fund, and to vest in such
Person  or   Persons,   in  such   capacity   and  for  the   benefit  of  the
Certificateholders,  such  title  to  the  Trust  Fund  or any  part  thereof,
whichever is applicable,  and, subject to the other provisions of this Section
8.10,  such  powers,  duties,  obligations,  rights  and  trusts as the Master
Servicer and the Trustee may consider  necessary or  desirable.  If the Master
Servicer  shall not have joined in such  appointment  within 15 days after the
receipt by it of a request to do so, or in the case an Event of Default  shall
have  occurred and be  continuing,  the Trustee  alone shall have the power to
make such  appointment.  No co-trustee or separate trustee  hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
8.06 and no notice to  Certificateholders of the appointment of any co-trustee
or separate trustee shall be required under Section 8.08.

                  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) To the extent necessary to effectuate the purposes
                   of this  Section  8.10,  all  rights,  powers,  duties  and
                   obligations  conferred or imposed upon the Trustee,  except
                   for the  obligation of the Trustee under this  Agreement to
                   advance  funds on behalf of the Master  Servicer,  shall be
                   conferred or imposed upon and exercised or performed by the
                   Trustee and such separate trustee or co-trustee jointly (it
                   being  understood that such separate  trustee or co-trustee
                   is not  authorized  to act  separately  without the Trustee
                   joining in such act),  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
                   applicable  Trust Fund or any  portion  thereof in any such
                   jurisdiction)  shall be exercised and  performed  singly by
                   such  separate  trustee  or  co-trustee,  but solely at the
                   direction of the Trustee;

                        (ii) No  trustee  hereunder  shall be held  personally
                   liable  by  reason  of any  act or  omission  of any  other
                   trustee hereunder and such appointment shall not, and shall
                   not be deemed to,  constitute any such separate  trustee or
                   co-trustee as agent of the Trustee;

                        (iii)  The   Trustee   may  at  any  time  accept  the
                   resignation   of  or  remove   any   separate   trustee  or
                   co-trustee; and

                        (iv) The Master Servicer,  and not the Trustee,  shall
                   be  liable  for the  payment  of  reasonable  compensation,
                   reimbursement  and  indemnification  to any  such  separate
                   trustee or co-trustee.

                  Any notice,  request or other  writing  given to the Trustee
shall be  deemed  to have  been  given to each of the  separate  trustees  and
co-trustees,  when and as  effectively  as if  given  to each of  them.  Every
instrument  appointing any separate  trustee or co-trustee shall refer to this
Agreement and the conditions of this Article VIII.  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 filed
with the  Trustee  and a copy  thereof  given to the Master  Servicer  and the
Depositor.

                  Any  separate  trustee  or  co-trustee  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.

Section 8.11.     Tax Matters.

                  It is  intended  that the assets  with  respect to which the
REMIC election pertaining to the Trust Fund is to be made, as set forth in the
Preliminary  Statement,  shall  constitute,  and that the  conduct  of matters
relating  to such assets  shall be such as to qualify  such assets as, a "real
estate mortgage  investment  conduit" as defined in and in accordance with the
REMIC Provisions.  In furtherance of such intention, the Trustee covenants and
agrees that it shall act as agent (and the Trustee is hereby  appointed to act
as agent) on behalf  of the  REMIC  and that in such  capacity  it shall:  (a)
prepare and file,  or cause to be prepared and filed,  in a timely  manner,  a
U.S. Real Estate Mortgage  Investment  Conduit Income Tax Return (Form 1066 or
any successor  form adopted by the Internal  Revenue  Service) and prepare and
file or cause to be prepared and filed with the Internal  Revenue  Service and
applicable  state or local tax authorities  income tax or information  returns
for each taxable year with respect to the REMIC,  containing such  information
and at the times and in the manner as may be  required by the Code or state or
local tax laws, regulations, or rules, and furnish or cause to be furnished to
Certificateholders the schedules,  statements or information at such times and
in such  manner as may be  required  thereby;  (b) within  thirty  days of the
Closing  Date,  furnish  or  cause to be  furnished  to the  Internal  Revenue
Service,  on Forms 8811 or as otherwise may be required by the Code, the name,
title,  address,  and  telephone  number of the person that the holders of the
Certificates may contact for tax information  relating thereto,  together with
such  additional  information as may be required by such Form, and update such
information at the time or times in the manner  required by the Code; (c) make
or cause to be made an election  that such assets be treated as a REMIC on the
federal  tax  return for its first  taxable  year (and,  if  necessary,  under
applicable  state law);  (d) prepare and forward,  or cause to be prepared and
forwarded,  to the Certificateholders and to the Internal Revenue Service and,
if necessary,  state tax authorities,  all information  returns and reports as
and  when  required  to be  provided  to them in  accordance  with  the  REMIC
Provisions,  including  without  limitation,  the  calculation of any original
issue  discount  using the  Prepayment  Assumption;  (e)  provide  information
necessary  for the  computation  of tax imposed on the  transfer of a Residual
Certificate  to a  Person  that is not a  Permitted  Transferee,  or an  agent
(including  a  broker,   nominee  or  other   middleman)  of  a  Non-Permitted
Transferee,  or a pass-through  entity in which a Non-Permitted  Transferee is
the  record  holder of an  interest  (the  reasonable  cost of  computing  and
furnishing such information may be charged to the Person liable for such tax);
(f) to the extent that they are under its control, conduct matters relating to
such  assets at all  times  that any  Certificates  are  outstanding  so as to
maintain the status as a REMIC under the REMIC  Provisions;  (g) not knowingly
or  intentionally  take any action or omit to take any action that would cause
the  termination of the REMIC status;  (h) pay, from the sources  specified in
the last  paragraph of this Section  8.11,  the amount of any federal or state
tax, including prohibited transaction taxes as described below, imposed on the
REMIC prior to its  termination  when and as the same shall be due and payable
(but such  obligation  shall not prevent the Trustee or any other  appropriate
Person from  contesting any such tax in appropriate  proceedings and shall not
prevent the Trustee from withholding payment of such tax, if permitted by law,
pending the outcome of such  proceedings);  (i) ensure that federal,  state or
local income tax or information returns shall be signed by the Trustee or such
other  person as may be required to sign such  returns by the Code or state or
local laws,  regulations or rules; (j) maintain records relating to the REMIC,
including  but not limited to the  income,  expenses,  assets and  liabilities
thereof and the fair market value and adjusted basis of the assets  determined
at such  intervals  as may be required  by the Code,  as may be  necessary  to
prepare the foregoing returns, schedules,  statements or information;  and (k)
as  and  when   necessary  and   appropriate,   represent  the  REMIC  in  any
administrative or judicial  proceedings relating to an examination or audit by
any governmental taxing authority,  request an administrative adjustment as to
any  taxable  year of the REMIC,  enter into  settlement  agreements  with any
governmental taxing agency,  extend any statute of limitations relating to any
tax item of the REMIC, and otherwise act on behalf of the REMIC in relation to
any tax matter or controversy involving it.

                  In order to enable the  Trustee to perform its duties as set
forth herein,  the Depositor  shall provide,  or cause to be provided,  to the
Trustee  within ten (10) days after the Closing Date all  information  or data
that the Trustee  requests in writing and  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 the  Certificates and the Mortgage Loans.  Thereafter,  the Depositor
shall provide to the Trustee  promptly upon written request  therefor any such
additional  information  or data  that the  Trustee  may,  from  time to time,
reasonably request in order to enable the Trustee to perform its duties as set
forth herein.  The Depositor  hereby  indemnifies  the Trustee for any losses,
liabilities,  damages,  claims or  expenses of the  Trustee  arising  from any
errors or  miscalculations  of the Trustee that result from any failure of the
Depositor to provide, or to cause to be provided, accurate information or data
to the Trustee on a timely basis.

                  In  the  event  that  any  tax  is  imposed  on  "prohibited
transactions"  of the REMIC as defined in Section  860F(a)(2)  of the Code, on
the "net income from foreclosure  property" of the REMIC as defined in Section
860G(c) of the Code,  on any  contribution  to the REMIC after the Startup Day
pursuant  to  Section  860G(d)  of the  Code,  or any  other  tax is  imposed,
including, without limitation, any minimum tax imposed upon the REMIC pursuant
to Sections  23153 and 24874 of the  California  Revenue and Taxation Code, if
not paid as otherwise  provided for herein,  such tax shall be paid by (i) the
Trustee,  if any such other tax arises out of or results  from a breach by the
Trustee  of any of its  obligations  under  this  Agreement,  (ii) the  Master
Servicer  or the  Seller,  in the case of any such  minimum  tax,  if such tax
arises out of or results from a breach by the Master Servicer or Seller of any
of their obligations under this Agreement or (iii) the Seller, if any such tax
arises out of or results from the Seller's obligation to repurchase a Mortgage
Loan  pursuant to Section 2.02 or 2.03 or (iv) in all other  cases,  or in the
event that the Trustee,  the Master  Servicer or the Seller fails to honor its
obligations  under the preceding clauses (i), (ii) or (iii), any such tax will
be paid with amounts otherwise to be distributed to the Certificateholders, as
provided in Section 3.11(b).

Section 8.12.     Periodic Filings.

                  Pursuant to written  instructions  from the  Depositor,  the
Trustee shall prepare,  execute and file all periodic  reports  required under
the Securities Exchange Act of 1934 in conformity with the terms of the relief
granted to the Depositor in CWMBS,  Inc.  (February 3, 1994),  a copy of which
has been  supplied  to the  Trustee  by the  Issuer.  In  connection  with the
preparation and filing of such periodic reports,  the Depositor and the Master
Servicer  shall  timely  provide  to  the  Trustee  all  material  information
available  to them which is required  to be  included in such  reports and not
known  to  them  to be in  the  possession  of  the  Trustee  and  such  other
information  as the Trustee  reasonably  may  request  from either of them and
otherwise  reasonably shall cooperate with the Trustee. The Trustee shall have
no  liability  with  respect to any failure to  properly  prepare or file such
periodic  reports  resulting  from or relating to the  Trustee's  inability or
failure to obtain any  information  not resulting  from its own  negligence or
willful misconduct.

                                  TERMINATION

Section 9.01.     Termination upon Liquidation or Purchase of 
                  all Mortgage Loans.

                  Subject   to   Section    9.03,    the    obligations    and
responsibilities of the Depositor, the Master Servicer and the Trustee created
hereby with respect to the Trust Fund shall  terminate upon the earlier of (a)
the purchase by the Master Servicer of all Mortgage Loans (and REO Properties)
remaining  in the Trust Fund at the price  equal to the sum of (i) 100% of the
Stated  Principal  Balance of each Mortgage Loan (other than in respect of REO
Property) plus one month's accrued interest thereon at the applicable Adjusted
Mortgage  Rate and  (ii)  the  lesser  of (x) the  appraised  value of any REO
Property  as  determined  by the  higher of two  appraisals  completed  by two
independent  appraisers  selected by the Master Servicer at the expense of the
Master  Servicer and (y) the Stated  Principal  Balance of each  Mortgage Loan
related to any REO  Property,  in each case plus  accrued and unpaid  interest
thereon at the applicable  Adjusted Mortgage Rate and (b) the later of (i) the
maturity or other  liquidation  (or any Advance with  respect  thereto) of the
last Mortgage Loan remaining in the Trust Fund and the  disposition of all REO
Property  and (ii)  the  distribution  to  Certificateholders  of all  amounts
required to be  distributed  to them pursuant to this  Agreement.  In no event
shall the  trusts  created  hereby  continue  beyond  the  earlier  of (i) the
expiration  of 21 years from the death of the survivor of the  descendants  of
Joseph P.  Kennedy,  the late  Ambassador of the United States to the Court of
St. James's,  living on the date hereof and (ii) the Latest Possible  Maturity
Date. The right to purchase all Mortgage Loans and REO Properties  pursuant to
clause (a) above shall be conditioned upon the Pool Stated Principal  Balance,
at the time of any such  repurchase,  aggregating less than ten percent of the
Cut-off Date Pool Principal Balance.

Section 9.02.     Final Distribution on the Certificates.

                  If on any Determination Date, the Master Servicer determines
that there are no  Outstanding  Mortgage Loans and no other funds or assets in
the Trust  Fund other than the funds in the  Certificate  Account,  the Master
Servicer shall direct the Trustee promptly to send a final distribution notice
to each  Certificateholder.  If the Master  Servicer  elects to terminate  the
Trust Fund  pursuant to clause (a) of Section  9.01, at least 20 days prior to
the date notice is to be mailed to the affected  Certificateholders the Master
Servicer  shall  notify the  Depositor  and the Trustee of the date the Master
Servicer intends to terminate the Trust Fund and of the applicable  repurchase
price of the Mortgage Loans and REO Properties.

                  Notice of any termination of the Trust Fund,  specifying the
Distribution Date on which Certificateholders may surrender their Certificates
for  payment  of the  final  distribution  and  cancellation,  shall  be given
promptly  by the  Trustee by letter to  Certificateholders  mailed not earlier
than the 15th day and not later than the 10th day of the month next  preceding
the month of such final  distribution.  Any such notice shall  specify (a) the
Distribution  Date upon which final  distribution on the Certificates  will be
made upon  presentation  and surrender of  Certificates  at the office therein
designated, (b) the amount of such final distribution, (c) the location of the
office or agency at which such  presentation  and surrender  must be made, and
(d) that the Record Date otherwise applicable to such Distribution Date is not
applicable,  distributions  being made only upon presentation and surrender of
the  Certificates  at the office therein  specified.  The Master Servicer will
give such  notice to each  Rating  Agency at the time such  notice is given to
Certificateholders.

                  In the event such notice is given, the Master Servicer shall
cause all funds in the  Certificate  Account to be remitted to the Trustee for
deposit  in  the  Distribution  Account  on  the  Business  Day  prior  to the
applicable  Distribution Date in an amount equal to the final  distribution in
respect of the Certificates. Upon such final deposit with respect to the Trust
Fund and the receipt by the Trustee of a Request  for  Release  therefor,  the
Trustee shall promptly  release to the Master  Servicer the Mortgage Files for
the Mortgage Loans.

                  Upon  presentation  and surrender of the  Certificates,  the
Trustee shall cause to be distributed to the Certificateholders of each Class,
in each  case on the  final  Distribution  Date and in the  order set forth in
Section  4.02, in the case of the  Certificateholders,  in proportion to their
respective  Percentage  Interests,  with respect to  Certificateholders of the
same Class,  an amount equal to (i) as to each Class of Regular  Certificates,
the  Certificate  Balance thereof plus accrued  interest  thereon (or on their
Notional Amount, if applicable) and (ii) as to the Residual Certificates,  the
amount,  if any, which remains on deposit in the  Distribution  Account (other
than the amounts retained to meet claims) after application pursuant to clause
(i) above.

                  In the event that any affected  Certificateholders shall not
surrender  Certificates  for  cancellation  within six  months  after the date
specified in the above  mentioned  written  notice,  the Trustee  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 six  months  after the  second  notice all the  applicable
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 and other
assets  which  remain a part of the Trust  Fund.  If within one year after the
second  notice  all   Certificates   shall  not  have  been   surrendered  for
cancellation,  the  Class  A-R  Certificateholders  shall be  entitled  to all
unclaimed  funds and  other  assets of the Trust  Fund  which  remain  subject
hereto.

Section 9.03.     Additional Termination Requirements.

                   (a) In the event the Master Servicer exercises its purchase
option as  provided in Section  9.01,  the Trust Fund shall be  terminated  in
accordance with the following additional requirements,  unless the Trustee has
been  supplied  with an  Opinion  of  Counsel,  at the  expense  of the Master
Servicer,  to the effect that the failure to comply with the  requirements  of
this  Section  9.03  will  not  (i)  result  in the  imposition  of  taxes  on
"prohibited transactions" on the REMIC as defined in Section 860F of the Code,
or (ii)  cause  the REMIC to fail to  qualify  as a REMIC at any time that any
Certificates are outstanding:

                             (1)   Within   90  days   prior   to  the   final
                   Distribution  Date  set  forth in the  notice  given by the
                   Master  Servicer  under Section 9.02,  the Master  Servicer
                   shall  prepare and the Trustee,  at the expense of the "tax
                   matters person", shall adopt a plan of complete liquidation
                   within the meaning of Section 860F(a)(4) of the Code which,
                   as evidenced by an Opinion of Counsel  (which opinion shall
                   not be an expense of the Trustee, the Tax Matters Person or
                   the Trust  Fund),  meets the  requirements  of a  qualified
                   liquidation; and

                             (2) Within 90 days after the time of  adoption of
                   such a plan of complete liquidation, the Trustee shall sell
                   all of the assets of the Trust Fund to the Master  Servicer
                   for cash in accordance with Section 9.01.

                   (b) The  Trustee  as agent for the REMIC  hereby  agrees to
adopt and sign such a plan of complete liquidation upon the written request of
the Master Servicer,  and the receipt of the Opinion of Counsel referred to in
Section  9.03(a)(1)  and to take such other action in connection  therewith as
may be reasonably requested by the Master Servicer.

                   (c) ______ By their  acceptance  of the  Certificates,  the
Holders  thereof  hereby  authorize  the Master  Servicer  to prepare  and the
Trustee to adopt and sign a plan of complete liquidation.

                           MISCELLANEOUS PROVISIONS

Section 10.01.    Amendment.

                  This  Agreement  may be  amended  from  time  to time by the
Depositor,  the Master  Servicer and the Trustee without the consent of any of
the  Certificateholders  (i) to cure any ambiguity or mistake, (ii) to correct
any defective provision herein or to supplement any provision herein which may
be inconsistent with any other provision herein, (iii) to add to the duties of
the  Depositor,  the  Seller  or the  Master  Servicer,  (iv) to add any other
provisions  with respect to matters or questions  arising  hereunder or (v) to
modify,  alter,  amend,  add to or  rescind  any of the  terms  or  provisions
contained in this Agreement; provided that any action pursuant to clauses (iv)
or (v) above shall not, as evidenced by an Opinion of Counsel  (which  Opinion
of  Counsel  shall  not be an  expense  of the  Trustee  or the  Trust  Fund),
adversely   affect   in   any   material   respect   the   interests   of  any
Certificateholder; provided, however, that no such Opinion of Counsel shall be
required if the Person  requesting  the  amendment  obtains a letter from each
Rating Agency stating that the amendment  would not result in the  downgrading
or withdrawal of the respective ratings then assigned to the Certificates;  it
being  understood  and agreed  that any such  letter in and of itself will not
represent a determination as to the materiality of any such amendment and will
represent a  determination  only as to the credit  issues  affecting  any such
rating.

                  The Trustee,  the Depositor and the Master Servicer also may
at any time and from time to time amend this Agreement  without the consent of
the Certificateholders to modify, eliminate or add to any of its provisions to
such extent as shall be necessary or helpful to (i) maintain the qualification
of the REMIC as a REMIC under the Code, (ii) avoid or minimize the risk of the
imposition of any tax on the REMIC  pursuant to the Code that would be a claim
at any time prior to the final  redemption of the Certificates or (iii) comply
with any other  requirements  of the Code,  provided that the Trustee has been
provided an Opinion of Counsel, which opinion shall be an expense of the party
requesting such opinion but in any case shall not be an expense of the Trustee
or the Trust Fund,  to the effect that such action is necessary or helpful to,
as  applicable,  (i) maintain such  qualification,  (ii) avoid or minimize the
risk  of  the  imposition  of  such  a tax  or  (iii)  comply  with  any  such
requirements of the Code.

                  This  Agreement may also be amended from time to time by the
Depositor, the Master Servicer and the Trustee with the consent of the Holders
of a Majority in Interest of each Class of Certificates  affected  thereby for
the  purpose  of  adding  any  provisions  to or  changing  in any  manner  or
eliminating  any of the  provisions  of this  Agreement or of modifying in any
manner the rights of the Holders of Certificates;  provided,  however, that no
such  amendment  shall (i)  reduce in any  manner  the amount of, or delay the
timing of, payments required to be distributed on any Certificate  without the
consent  of the  Holder  of such  Certificate,  (ii)  adversely  affect in any
material  respect the interests of the Holders of any Class of Certificates in
a manner other than as described in (i), without the consent of the Holders of
Certificates of such Class evidencing,  as to such Class, Percentage Interests
aggregating 66%, or (iii) reduce the aforesaid percentages of Certificates the
Holders of which are  required to consent to any such  amendment,  without the
consent of the Holders of all such Certificates 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, which opinion shall not be an
expense of the  Trustee or the Trust Fund,  to the effect that such  amendment
will   not   cause   the   imposition   of  any  tax  on  the   REMIC  or  the
Certificateholders  or cause  the REMIC to fail to  qualify  as a REMIC at any
time that any Certificates are outstanding.

                  Promptly  after  the  execution  of any  amendment  to  this
Agreement  requiring  the consent of  Certificateholders,  the  Trustee  shall
furnish  written  notification of the substance or a copy of such amendment to
each Certificateholder and each Rating Agency.

                  It   shall   not   be   necessary   for   the   consent   of
Certificateholders  under this Section 10.01 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.

                  Nothing in this Agreement shall require the Trustee to enter
into an amendment without receiving an Opinion of Counsel (which Opinion shall
not be an  expense  of the  Trustee or the Trust  Fund),  satisfactory  to the
Trustee that (i) such  amendment is permitted  and is not  prohibited  by this
Agreement  and that all  requirements  for amending this  Agreement  have been
complied with; and (ii) either (A) the amendment does not adversely  affect in
any  material  respect  the  interests  of any  Certificateholder  or (B)  the
conclusion set forth in the immediately  preceding  clause (A) is not required
to be reached pursuant to this Section 10.01.

Section 10.02.    Recordation of Agreement; Counterparts.

                  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 at its
expense,  but only upon direction by the Trustee  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.    Governing Law.

                  THIS  AGREEMENT  SHALL BE CONSTRUED IN  ACCORDANCE  WITH AND
GOVERNED  BY THE  SUBSTANTIVE  LAWS OF THE  STATE  OF NEW YORK  APPLICABLE  TO
AGREEMENTS  MADE  AND  TO BE  PERFORMED  IN THE  STATE  OF NEW  YORK  AND  THE
OBLIGATIONS,   RIGHTS   AND   REMEDIES   OF  THE   PARTIES   HERETO   AND  THE
CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 10.04.    Intention of Parties.

                  It is the  express  intent of the  parties  hereto  that the
conveyance  (i) of the Mortgage  Loans by the Seller to the Depositor and (ii)
of the Trust Fund by the  Depositor  to the Trustee  each be, and be construed
as, an absolute sale thereof. It is, further, not the intention of the parties
that such conveyances be deemed a pledge thereof.  However, in the event that,
notwithstanding  the  intent of the  parties,  such  assets are held to be the
property of the Seller or  Depositor,  as the case may be, or if for any other
reason  this  Agreement  is held or deemed to create a  security  interest  in
either such assets,  then (i) this Agreement  shall be deemed to be a security
agreement  within the meaning of the Uniform  Commercial  Code of the State of
New York and (ii) the  conveyances  provided  for in this  Agreement  shall be
deemed to be an  assignment  and a grant (i) by the Seller to the Depositor or
(ii)   by  the   Depositor   to  the   Trustee,   for  the   benefit   of  the
Certificateholders,  of a security interest in all of the assets  transferred,
whether now owned or hereafter acquired.

                  The  Seller  and  the  Depositor  for  the  benefit  of  the
Certificateholders  shall, to the extent consistent with this Agreement,  take
such actions as may be necessary to ensure that, if this Agreement were deemed
to create a security  interest in the Trust Fund, such security interest would
be  deemed  to be a  perfected  security  interest  of  first  priority  under
applicable  law and  will be  maintained  as such  throughout  the term of the
Agreement.  The Depositor shall arrange for filing any Uniform Commercial Code
continuation  statements in connection with any security  interest  granted or

expenses,  and liabilities to be incurred therein or thereby, and the Trustee,
for 60 days after its receipt of such  notice,  request and offer of indemnity
shall  have  neglected  or  refused  to  institute  any such  action,  suit or
proceeding;  it being understood and intended,  and being expressly covenanted
by each Certificateholder with every other  Certificateholder and the Trustee,
that no one or more Holders of Certificates shall have any right in any manner
whatever by virtue or by availing  itself or themselves  of any  provisions of
this  Agreement to affect,  disturb or prejudice  the rights of the Holders of
any other of the Certificates, or to obtain or seek to obtain priority over or
preference  to any other  such  Holder or to  enforce  any  right  under  this
Agreement,  except in the manner herein provided and for the common benefit of
all  Certificateholders.  For the protection and enforcement of the provisions

hours, to examine all the books of account,  records, reports and other papers
of the Master  Servicer  relating to the  Mortgage  Loans,  to make copies and
extracts therefrom, to cause such books to be audited by independent certified
public accountants selected by the Depositor or the Trustee and to discuss its
affairs,  finances  and  accounts  relating  to the  Mortgage  Loans  with its
officers,  employees and independent public accountants (and by this provision
the Master  Servicer hereby  authorizes said  accountants to discuss with such
representative  such affairs,  finances and accounts),  all at such reasonable
times and as often as may be reasonably  requested.  Any out-of-pocket expense
incident to the  exercise by the  Depositor  or the Trustee of any right under

other such  expenses  shall be borne by the  Master  Servicer  or the  related
Subservicer.

                  It   is    the    intention    of   the    Depositor    that
Certificate-holders  shall not be  personally  liable for  obligations  of the
Trust  Fund,  that  the  interests  in  the  Trust  Fund  represented  by  the
Certificates  shall be nonassessable for any reason  whatsoever,  and that the
Certificates,  upon due authentication thereof by the Trustee pursuant to this

         Representations and Warranties of the Seller/Master Servicer


                  IndyMac,  Inc.  ("IndyMac") hereby makes the representations
and warranties set forth in this Schedule II to the Depositor and the Trustee,
as of the Closing  Date,  or if so specified  herein,  as of the Cut-off Date.
Capitalized  terms used but not  otherwise  defined in this  Schedule II shall

"Pooling and Servicing  Agreement") relating to the  above-referenced  Series,
among IndyMac, as seller and master servicer,  CWMBS, Inc., as depositor,  and
The Bank of New York, as trustee.

                   (1) IndyMac is duly organized as a Delaware corporation and
         is validly  existing and in good standing under the laws of the State
         of Delaware and is duly  authorized and qualified to transact any and
         all business  contemplated by the Pooling and Servicing  Agreement to
         be conducted by IndyMac in any state in which a Mortgaged Property is
         located or is otherwise not required  under  applicable law to effect
         such qualification and, in any event, is in compliance with the doing
         business  laws of any such state,  to the extent  necessary to ensure
         its ability to enforce each  Mortgage  Loan,  to service the Mortgage
         Loans in  accordance  with the  terms of the  Pooling  and  Servicing
         Agreement  and to  perform  any of its  other  obligations  under the
         Pooling and Servicing Agreement in accordance with the terms thereof.

                   (2) IndyMac has the full  corporate  power and authority to
         sell and service  each  Mortgage  Loan,  and to execute,  deliver and
         perform,   and  to  enter  into  and  consummate   the   transactions
         contemplated  by the Pooling  and  Servicing  Agreement  and has duly
         authorized by all necessary  corporate  action on the part of IndyMac
         the execution,  delivery and performance of the Pooling and Servicing
         Agreement; and the Pooling and Servicing Agreement,  assuming the due
         authorization,  execution  and delivery  thereof by the other parties
         thereto,  constitutes  a  legal,  valid  and  binding  obligation  of
         IndyMac,  enforceable  against  IndyMac in accordance with its terms,
         except  that  (a)  the  enforceability  thereof  may  be  limited  by
         bankruptcy,  insolvency,  moratorium,  receivership and other similar
         laws  relating to creditors'  rights  generally and (b) the remedy of
         specific  performance  and  injunctive  and other forms of  equitable
         relief may be subject to equitable  defenses and to the discretion of
         the court before which any proceeding therefor may be brought.

                   (3) The execution and delivery of the Pooling and Servicing
         Agreement by IndyMac, the sale and servicing of the Mortgage Loans by
         IndyMac under the Pooling and Servicing  Agreement,  the consummation
         of any other of the  transactions  contemplated  by the  Pooling  and
         Servicing  Agreement,  and the  fulfillment of or compliance with the
         terms  thereof are in the ordinary  course of business of IndyMac and
         will not (A) result in a material  breach of any term or provision of
         the charter or by-laws of IndyMac or (B)  materially  conflict  with,
         result in a material breach,  violation or acceleration of, or result
         in a  material  default  under,  the  terms  of  any  other  material
         agreement or  instrument  to which  IndyMac is a party or by which it
         may be bound, or (C) constitute a material  violation of any statute,
         order or regulation  applicable  to IndyMac of any court,  regulatory
         body,  administrative agency or governmental body having jurisdiction
         over  IndyMac;  and  IndyMac  is not in  breach or  violation  of any
         material indenture or other material  agreement or instrument,  or in
         violation  of  any  statute,   order  or  regulation  of  any  court,
         regulatory body,  administrative  agency or governmental  body having
         jurisdiction  over it which breach or violation may materially impair
         IndyMac's ability to perform or meet any of its obligations under the
         Pooling and Servicing Agreement.

                   (4) No  litigation  is pending or, to the best of IndyMac's
         knowledge,   threatened  against  IndyMac  that  would  prohibit  the
         execution  or  delivery  of, or  performance  under,  the Pooling and
         Servicing Agreement by IndyMac.

                                 SCHEDULE III


                                  CWMBS, Inc.
                      Mortgage Pass-Through Certificates
                                 Series 1998-K


            Representations and Warranties as to the Mortgage Loans


                  IndyMac,  Inc.  ("IndyMac") hereby makes the representations
and  warranties  set  forth  in this  Schedule  III to the  Depositor  and the
Trustee,  as of the Closing Date, or if so specified herein, as of the Cut-off
Date or date of origination of the Mortgage Loan.  Capitalized  terms used but
not otherwise  defined in this  Schedule III shall have the meanings  ascribed
thereto in the Pooling and  Servicing  Agreement  (the  "Pooling and Servicing
Agreement") relating to the above-referenced  Series, among IndyMac, as seller
and master servicer,  CWMBS, Inc., as depositor,  and The Bank of New York, as
trustee.

                   (1) The  information set forth on Schedule I to the Pooling
         and  Servicing  Agreement  with respect to each Mortgage Loan is true
         and correct in all material respects as of the Closing Date.

                   (2) As of the Closing Date, all regularly  scheduled monthly
         payments due with respect to each  Mortgage  Loan up to and including
         the Due Date  immediately  prior to the Cut-off  Date have been made;
         and  as of  the  Cut-off  Date,  no  Mortgage  Loan  had a  regularly
         scheduled  monthly payment that was 60 or more days Delinquent during
         the twelve months prior to the Cut-off Date.

                   (3)  With  respect  to  any  Mortgage  Loan  that  is not a
         Cooperative Loan, each Mortgage is a valid and enforceable first lien
         on  the  Mortgaged   Property   subject  only  to  (a)  the  lien  of
         nondelinquent  current real property taxes and  assessments 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 unit
         in a condominium  project or planned unit  development,  any lien for
         common charges  permitted by statute or homeowner  association  fees,
         (b) covenants, conditions and restrictions,  rights of way, easements
         and other  matters of public  record as of the date of  recording  of
         such Mortgage,  such  exceptions  appearing of record being generally
         acceptable to mortgage  lending  institutions in the area wherein the
         related  Mortgaged  Property is located or specifically  reflected in
         the appraisal made in connection  with the origination of the related
         Mortgage  Loan,  and (c) other matters to which like  properties  are
         commonly subject which do not materially  interfere with the benefits
         of the security intended to be provided by such Mortgage.

                   (4)  Immediately  prior to the  assignment  of the Mortgage
         Loans to the  Depositor,  the  Seller  had good title to, and was the
         sole owner of, each Mortgage Loan free and clear of any pledge, lien,
         encumbrance  or security  interest and had full right and  authority,
         subject to no interest or  participation  of, or agreement  with, any
         other party,  to sell and assign the same pursuant to the Pooling and
         Servicing Agreement.

                   (5) As of the date of  origination  of each Mortgage  Loan,
         there was no delinquent  tax or  assessment  lien against the related
         Mortgaged Property.

                   (6) There is no valid offset,  defense or  counterclaim  to
         any  Mortgage  Note or  Mortgage,  including  the  obligation  of the
         Mortgagor to pay the unpaid principal of or interest on such Mortgage
         Note.

                   (7) There are no mechanics' liens or claims for work, labor
         or material  affecting any Mortgaged  Property  which are or may be a
         lien prior to, or equal with, the lien of such Mortgage, except those
         which are insured against by the title  insurance  policy referred to
         in item (11) below.

                   (8) To the best of the  Seller's  knowledge,  no  Mortgaged
         Property  has been  materially  damaged by water,  fire,  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  representation)  so as to affect adversely
         the value of the related  Mortgaged  Property  as  security  for such
         Mortgage Loan.

                   (9)  Each  Mortgage  Loan at  origination  complied  in all
         material respects with applicable state and federal laws,  including,
         without  limitation,  usury,  equal credit  opportunity,  real estate
         settlement  procedures,  truth-in-lending  and disclosure laws or any
         noncompliance does not have a material adverse effect on the value of
         the related Mortgage Loan.

                   (10) As of the Closing  Date,  the Seller has not  modified
         the Mortgage in any material respect (except that a Mortgage Loan may
         have been modified by a written instrument which has been recorded or
         submitted for recordation,  if necessary, to protect the interests of
         the  Certificateholders and which has been delivered to the Trustee);
         satisfied,  cancelled or  subordinated  such  Mortgage in whole or in
         part;  released  the related  Mortgaged  Property in whole or in part
         from  the  lien of such  Mortgage;  or  executed  any  instrument  of
         release,  cancellation,  modification  or  satisfaction  with respect
         thereto.

                   (11) A lender's policy of title  insurance  together with a
         condominium   endorsement  and  extended  coverage  endorsement,   if
         applicable,  in an amount at least equal to the  Cut-off  Date Stated
         Principal Balance of each such Mortgage Loan or a commitment (binder)
         to issue the same was  effective  on the date of the  origination  of
         each  Mortgage  Loan,  each such  policy is valid and remains in full
         force and effect.

                   (12) Each Mortgage Loan was originated  (within the meaning
         of  Section  3(a)(41)  of the  Securities  Exchange  Act of 1934,  as
         amended) by an entity that satisfied at the time of  origination  the
         requirements  of Section  3(a)(41) of the Securities  Exchange Act of
         1934, as amended.

                   (13) To the  best  of the  Seller's  knowledge,  all of the
         improvements  which were 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 such failure to be wholly within such boundaries and
         restriction lines or such encroachment,  as the case may be, does not
         have a material effect on the value of such Mortgaged Property.

                   (14) To the best of the Seller's knowledge,  as of the date
         of origination  of each Mortgage  Loan, no improvement  located on or
         being  part  of  the  Mortgaged  Property  is  in  violation  of  any
         applicable  zoning law or regulation  unless such violation would not
         have a material adverse effect on the value of the related  Mortgaged
         Property.  To the best of the Seller's  knowledge,  all  inspections,
         licenses and certificates  required to be made or issued with respect
         to all occupied portions of the Mortgaged  Property and, with respect
         to the use and  occupancy of the same,  including  but not limited to
         certificates of occupancy and fire  underwriting  certificates,  have
         been made or obtained from the  appropriate  authorities,  unless the
         lack thereof would not have a material adverse effect on the value of
         such Mortgaged Property.

                   (15)  The  Mortgage  Note  and  the  related  Mortgage  are
         genuine,  and each is the legal,  valid and binding obligation of the
         maker  thereof,  enforceable  in accordance  with its terms and under
         applicable law.

                   (16) The  proceeds  of the  Mortgage  Loan have been  fully
         disbursed and there is no requirement for future advances thereunder.

                   (17)  The   related   Mortgage   contains   customary   and
         enforceable  provisions  which  render the rights and remedies of the
         holder  thereof  adequate for the  realization  against the Mortgaged
         Property of the benefits of the security,  including, (i) in the case
         of a Mortgage  designated as a deed of trust,  by trustee's sale, and
         (ii) otherwise by judicial foreclosure.

                   (18) With respect to each Mortgage  constituting  a deed of
         trust,  a trustee,  duly qualified  under  applicable law to serve as
         such,  has been  properly  designated  and currently so serves and is
         named in such  Mortgage,  and no fees or expenses  are or will become
         payable by the  Certificateholders  to the trustee  under the deed of
         trust,  except in connection  with a trustee's  sale after default by
         the Mortgagor.

                   (19)  At the  Cut-off  Date,  the  improvements  upon  each
         Mortgaged  Property  are  covered  by a  valid  and  existing  hazard
         insurance  policy with a generally  acceptable  carrier that provides
         for fire and extended coverage and coverage for such other hazards as
         are  customarily  required by  institutional  single family  mortgage
         lenders in the area where the Mortgaged Property is located,  and the
         Seller has  received  no notice  that any  premiums  due and  payable
         thereon have not been paid;  the  Mortgage  obligates  the  Mortgagor
         thereunder to maintain all such insurance  including  flood insurance
         at the Mortgagor's cost and expense. Anything to the contrary in this
         item (19)  notwithstanding,  no  breach  of this  item (19)  shall be
         deemed to give rise to any  obligation of the Seller to repurchase or
         substitute  for such  affected  Mortgage Loan or Loans so long as the
         Master  Servicer  maintains a blanket  policy  pursuant to the second
         paragraph of Section 3.12(a) of the Pooling and Servicing Agreement.

                   (20) If at the time of  origination  of each Mortgage Loan,
         related the Mortgaged  Property was in an area then identified in the
         Federal Register by the Federal Emergency Management Agency as having
         special flood hazards, a flood insurance policy in a form meeting the
         then-current requirements of the Flood Insurance Administration is in
         effect  with  respect to such  Mortgaged  Property  with a  generally
         acceptable carrier.

                   (21) To the  best of the  Seller's  knowledge,  there is no
         proceeding   pending   or   threatened   for  the  total  or  partial
         condemnation  of any  Mortgaged  Property,  nor is such a  proceeding
         currently occurring.

                   (22)  To  best  of  the  Seller's  knowledge,  there  is no
         material event which, with the passage of time or with notice and the
         expiration of any grace or cure period,  would  constitute a material
         non-monetary  default,  breach,  violation  or event of  acceleration
         under the Mortgage or the related  Mortgage  Note; and the Seller has
         not waived any material  non-monetary default,  breach,  violation or
         event of acceleration.

                   (23)  Each  Mortgage  File  contains  an  appraisal  of the
         related Mortgaged Property in a form acceptable to FNMA or FHLMC.

                   (24) Any  leasehold  estate  securing a Mortgage Loan has a
         stated  term at  least as long as the  term of the  related  Mortgage
         Loan.

                   (25)  Each  Mortgage  Loan  was  selected  from  among  the
         outstanding  fixed-rate  one- to  four-family  mortgage  loans in the
         Seller's   portfolio   at  the   Closing   Date  as  to   which   the
         representations  and  warranties  made with  respect to the  Mortgage
         Loans set forth in this Schedule III can be made.  No such  selection
         was made in a manner  intended to adversely  affect the  interests of
         the Certificateholders.

                   (26) No more than 0.39% of the Mortgage Loans in Loan Group
         1 (by aggregate  Stated  Principal  Balance of the Mortgage  Loans in
         Loan  Group 1) and  none of the  Mortgage  Loans in Loan  Group 2 are
         Cooperative Loans.

                   (27)  Each   Cooperative   Loan  is  secured  by  a  valid,
         subsisting and enforceable perfected first lien and security interest
         in the related Mortgaged Property,  subject only to (i) the rights of
         the  Cooperative  Corporation to collect  Maintenance and assessments
         from the Mortgagor, (ii) the lien of the Blanket Mortgage, if any, on
         the Cooperative  Property and of real property taxes, water and sewer
         charges,  rents and assessments on the  Cooperative  Property not yet
         due and payable,  and (iii) other  matters to which like  Cooperative
         Units are commonly subject which do not materially interfere with the
         benefits of the  security  intended  to be  provided by the  Security
         Agreement  or the  use,  enjoyment,  value  or  marketability  of the
         Cooperative Unit. Each original UCC financing statement, continuation
         statement or other  governmental  filing or recordation  necessary to
         create or preserve the  perfection and priority of the first priority
         lien and security interest in the Cooperative  Shares and Proprietary
         Lease has been timely and  properly  made.  Any  security  agreement,
         chattel  mortgage or equivalent  document  related to the Cooperative
         Loan and delivered to the Sponsor or its designee  establishes in the
         Seller a valid and  subsisting  perfected  first lien on and security
         interest in the property described  therein,  and the Seller has full
         right to sell and assign the same.

                   (28)   Each   Cooperative   Corporation   qualifies   as  a
         "cooperative  housing  corporation"  as defined in Section 216 of the
         Code.

         [No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under said Act and such laws. In the event that a
transfer is to be made in reliance upon an exemption from the Securities Act
and such laws, in order to assure compliance with the Securities Act and such
laws, the Certificateholder desiring to effect such transfer and such
Certificateholder's prospective transferee shall each certify to the Trustee
in writing the facts surrounding the transfer. In the event that such a

to the Trustee an Opinion of Counsel that such transfer may be made pursuant
to an exemption from the Securities Act and such state securities laws, which
Opinion of Counsel shall not be obtained at the expense of the Trustee, the

satisfactory to the Trustee, to the effect that such transferee is not an
employee benefit plan subject to Section 406 of ERISA or Section 4975 of the
Code, nor a person acting on behalf of any such plan, which representation
letter shall not be an expense of the Trustee or the Master Servicer, (ii) if
the purchaser is an insurance company, a representation that the purchaser is
an insurance company which is purchasing such Certificates with funds
contained in an "insurance company general account" (as such term is defined
in Section V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE
95-60")) and that the purchase and holding of such Certificates are covered
under PTCE 95-60 or (iii) in the case of any such Certificate presented for
registration in the name of an employee benefit plan subject to ERISA or
Section 4975 of the Code (or comparable provisions of any subsequent
enactments), or a trustee of any such plan or any other person acting on
behalf of any such plan, an Opinion of Counsel satisfactory to the Trustee and
the Master Servicer to the effect that the purchase or holding of such
Certificate will not result in the assets of the Trust Fund being deemed to be
"plan assets" and subject to the prohibited transaction provisions of ERISA
and the Code and will not subject the Trustee to any obligation in addition to
those undertaken in the Agreement, which Opinion of Counsel shall not be an
expense of the Trustee or the Master Servicer. [Such representation shall be
deemed to have been made to the Trustee by the Transferee's acceptance of a
Certificate of this Class and by a beneficial owner's acceptance of its
interest in a Certificate of this Class.] Notwithstanding anything else to the
contrary herein, any purported transfer of a Certificate of this Class to or
on behalf of an employee benefit plan subject to ERISA or to the Code without
the opinion of counsel satisfactory to the Trustee as described above shall be
void and of no effect.

         with respect to a Trust Fund consisting primarily of a pool of
         conventional mortgage loans (the "Mortgage Loans") secured by first
         liens on one- to four-family residential properties.

                           CWMBS, Inc., as Depositor

         Principal in respect of this Certificate is distributable monthly as
set forth herein. Accordingly, the Certificate Balance at any time may be less
than the Certificate Balance as set forth herein. This Certificate does not
evidence an obligation of, or an interest in, and is not guaranteed by the
Depositor, the Seller, the Master Servicer or the Trustee referred to below or
any of their respective affiliates. Neither this Certificate nor the Mortgage
Loans are guaranteed or insured by any governmental agency or instrumentality.

         This certifies that __________________________________ is the
registered owner of the Percentage Interest (obtained by dividing the
denomination of this Certificate by the aggregate Initial Certificate Balances
of the denominations of all Certificates of the Class to which this
Certificate belongs) in certain monthly distributions with respect to a Trust
Fund consisting of the Mortgage Loans deposited by CWMBS, Inc. (the
"Depositor"). The Trust Fund was created pursuant to a Pooling and Servicing
Agreement dated as of the Cut-off Date specified above (the "Agreement") among
the Depositor, IndyMac, Inc., as seller (in such capacity, the "Seller") and
as master servicer (in such capacity, the "Master Servicer"), and The Bank of
New York, as trustee (the "Trustee"). To the extent not defined herein, the
capitalized terms used herein have the meanings assigned 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.

         Any distribution of the proceeds of any remaining assets of the Trust
Fund will be made only upon presentment and surrender of this Class A-R
Certificate at the Corporate Trust Office or the office or agency maintained
by the Trustee in New York, New York.

         No transfer of a Class A-R Certificate shall be made unless the
Trustee shall have received either (i) a representation [letter] from the
transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Trustee, to the effect that such transferee is not an
employee benefit plan subject to Section 406 of ERISA or Section 4975 of the
Code, nor a person acting on behalf of any such plan, which representation
letter shall not be an expense of the Trustee or the Master Servicer, (ii) if
the purchaser is an insurance company, a representation that the purchaser is
an insurance company which is purchasing such Certificate with funds contained
in an "insurance company general account" (as such term is defined in Section
V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE 95-60")) and that
the purchase and holding of such Certificate are covered under PTCE 95-60 or
(iii) in the case of any such Certificate presented for registration in the
name of an employee benefit plan subject to ERISA or Section 4975 of the Code
(or comparable provisions of any subsequent enactments), or a trustee of any
such plan or any other person acting on behalf of any such plan, an Opinion of
Counsel satisfactory to the Trustee and the Master Servicer to the effect that
the purchase or holding of such Class A-R Certificate will not result in the
assets of the Trust Fund being deemed to be "plan assets" and subject to the
prohibited transaction provisions of ERISA and the Code and will not subject
the Trustee to any obligation in addition to those undertaken in the
Agreement, which Opinion of Counsel shall not be an expense of the Trustee or
the Master Servicer. [Such representation shall be deemed to have been made to
the Trustee by the Transferee's acceptance of this Class A-R Certificate and
by a beneficial owner's acceptance of its interest in such Certificate.]
Notwithstanding anything else to the contrary herein, any purported transfer
of a Class A-R Certificate to or on behalf of an employee benefit plan subject
to ERISA or to the Code without the opinion of counsel satisfactory to the
Trustee as described above shall be void and of no effect.

         Each Holder of this Class A-R Certificate will be deemed to have
agreed to be bound by the restrictions of the Agreement, including but not
limited to the restrictions that (i) each person holding or acquiring any
Ownership Interest in this Class A-R Certificate must be a Permitted
Transferee, (ii) no Ownership Interest in this Class A-R Certificate may be
transferred without delivery to the Trustee of (a) a transfer affidavit of the
proposed transferee and (b) a transfer certificate of the transferor, each of
such documents to be in the form described in the Agreement, (iii) each person
holding or acquiring any Ownership Interest in this Class A-R Certificate must
agree to require a transfer affidavit and to deliver a transfer certificate to
the Trustee as required pursuant to the Agreement, (iv) each person holding or
acquiring an Ownership Interest in this Class A-R Certificate must agree not
to transfer an Ownership Interest in this Class A-R Certificate if it has
actual knowledge that the proposed transferee is not a Permitted Transferee
and (v) any attempted or purported transfer of any Ownership Interest in this
Class A-R Certificate in violation of such restrictions will be absolutely
null and void and will vest no rights in the purported transferee.

         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 shall not be entitled to any benefit under the
Agreement or be valid for any purpose unless manually countersigned by an
authorized signatory of the Trustee.

         IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

                       [Form of Reverse of Certificates]


                                  CWMBS, INC.
                      Mortgage Pass-Through Certificates

         This Certificate is one of a duly authorized issue of Certificates
designated as CWMBS, Inc. Mortgage Pass-Through Certificates, of the Series
specified on the face hereof (herein collectively called the "Certificates"),
and representing a beneficial ownership interest in the Trust Fund created by
the Agreement.

         The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account
for payment hereunder and that the Trustee is not liable to the
Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations
of rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         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 on the face hereof, to the Person in
whose name this Certificate is registered at the close of business on the
applicable Record Date in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Certificates of the Class to which this Certificate
belongs on such Distribution Date pursuant to the Agreement. The Record Date
applicable to each Distribution Date is the last Business Day of the month
next preceding the month of such Distribution Date.

         Distributions on this Certificate shall be made by wire transfer of
immediately available funds to the account of the Holder hereof at a bank or
other entity having appropriate facilities therefor, if such Certificateholder
shall have so notified the Trustee in writing at least five Business Days
prior to the related Record Date and such Certificateholder shall satisfy the
conditions to receive such form of payment set forth in the Agreement, or, if
not, by check mailed by first class mail to the address of such
Certificateholder appearing in the Certificate Register. The final
distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the Corporate Trust Office or
such other location specified in the notice to Certificateholders of such
final distribution.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any
time by the Depositor, the Master Servicer and the Trustee with the consent of
the Holders of Certificates affected by such amendment evidencing the
requisite Percentage Interest, as provided in the Agreement. 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 therefor or in lieu hereof
whether or not notation of such consent is made upon this Certificate. The
Agreement also permits the amendment thereof, in certain limited
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 of the Trustee upon surrender of this Certificate for
registration of transfer at the Corporate Trust Office or the office or agency
maintained by the Trustee in New York, New York, accompanied by a 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 the same
Class in authorized denominations and evidencing the same aggregate Percentage
Interest in the Trust Fund will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in 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 the same Class in authorized
denominations and evidencing the same 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 may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

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

         On any Distribution Date on which the Pool Stated Principal Balance
is less than 10% of the Cut-off Date Pool Principal Balance, the Master
Servicer will have the option to repurchase, in whole, from the Trust Fund all
remaining Mortgage Loans and all property acquired in respect of the Mortgage
Loans at a purchase price determined as provided in the Agreement. In the
event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the later of the
maturity or other liquidation (or any advance with respect thereto) of the
last Mortgage Loan remaining in the Trust Fund or the disposition of all
property in respect thereof and the distribution to Certificateholders of all
amounts required to be distributed pursuant to the Agreement. In no event,
however, will the trust created by the Agreement continue beyond the
expiration of 21 years from the death of the last survivor of the descendants
living at the date of the Agreement of a certain person named in the
Agreement.

         Any term used herein that is defined in the Agreement shall have the
meaning assigned in the Agreement, and nothing herein shall be deemed
inconsistent with that meaning.

is sufficient to transfer all right, title and interest of the party so
endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or
(ii) any assignment is in recordable form or sufficient to effect the
assignment of and transfer to the assignee thereof, under the Mortgage to
which the assignment relates.

STATE OF     )
             ) ss.:
COUNTY OF    )


         The undersigned, being first duly sworn, deposes and says as follows:

         1. The undersigned is an officer of _____________________ , the
proposed Transferee of an Ownership Interest in a Class A-R Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, (the
"Agreement"), relating to the above-referenced Series, by and among CWMBS,
Inc., as depositor (the "Depositor"), IndyMac, Inc., as seller and master
servicer and The Bank of New York, as Trustee. Capitalized terms used, but not
defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to
such terms in the Agreement. The Transferee has authorized the undersigned to
make this affidavit on behalf of the Transferee.

         2. The Transferee is, as of the date hereof, and will be, as of the
date of the Transfer, a Permitted Transferee. The Transferee is acquiring its
Ownership Interest in the Certificate either (i) for its own account or (ii)
as nominee, trustee or agent for another Person and has attached hereto an
affidavit from such Person in substantially the same form as this affidavit.
The Transferee has no knowledge that any such affidavit is false.

         3. The Transferee has been advised of, and understands that (i) a tax
will be imposed on Transfers of the Certificate to Persons that are not
Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if
such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability
for the tax if the subsequent Transferee furnished to such Person an affidavit
that such subsequent Transferee is a Permitted Transferee and, at the time of
Transfer, such Person does not have actual knowledge that the affidavit is
false.

         4. The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee is the record holder of an interest in such entity. The
Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is a Permitted Transferee and the
pass-through entity does not have actual knowledge that such affidavit is
false. (For this purpose, a "pass-through entity" includes a regulated
investment company, a real estate investment trust or common trust fund, a
partnership, trust or estate, and certain cooperatives and, except as may be
provided in Treasury Regulations, persons holding interests in pass-through
entities as a nominee for another Person.)

         5. The Transferee has reviewed the provisions of Section 5.02(c) of
the Agreement (attached hereto as Exhibit 2 and incorporated herein by
reference) and understands the legal consequences of the acquisition of an
Ownership Interest in the Certificate including, without limitation, the
restrictions on subsequent Transfers and the provisions regarding voiding the
Transfer and mandatory sales. The Transferee expressly agrees to be bound by
and to abide by the provisions of Section 5.02(c) of the Agreement and the
restrictions noted on the face of the Certificate. The Transferee understands
and agrees that any breach of any of the representations included herein shall
render the Transfer to the Transferee contemplated hereby null and void.

         6. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in
the Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth as Exhibit J to the Agreement (a "Transferor Certificate") to
the effect that such Transferee has no actual knowledge that the Person to
which the Transfer is to be made is not a Permitted Transferee.

         7. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect
to the Certificate.

         8. The Transferee's taxpayer identification number is _____________ .

         9. The Transferee is a U.S. Person as defined in Code Section
7701(a)(30).

         10. The Transferee is aware that the Certificate may be a
"noneconomic residual interest" within the meaning of proposed Treasury
regulations promulgated pursuant to the Code and that the transferor of a
noneconomic residual interest will remain liable for any taxes due with
respect to the income on such residual interest, unless no significant purpose
of the transfer was to impede the assessment or collection of tax.

         11. The Transferee is not an employee benefit plan that is subject to
ERISA or a plan that is subject to Section 4975 of the Code, and the
Transferee is not acting on behalf of such a plan.

                           *        *        *

                                                                  to EXHIBIT I

                              Certain Definitions

         "Ownership Interest": As to any Certificate, any ownership interest
in such Certificate, including any interest in such Certificate as the Holder
thereof and any other interest therein, whether direct or indirect, legal or
beneficial.

         "Permitted Transferee": Any Person other than (i) the United States,
any State or political subdivision thereof, or any agency or instrumentality
of any of the foregoing, (ii) a foreign government, International Organization
or any agency or instrumentality of either of the foregoing, (iii) an
organization (except certain farmers' cooperatives described in Code Section
521) which is exempt from tax imposed by Chapter 1 of the Code (including the
tax imposed by Code Section 511 on unrelated business taxable income) on any
excess inclusions (as defined in Code Section 860E(c)(1)) with respect to any
Class A-R Certificate, (iv) rural electric and telephone cooperatives
described in Code Section 1381(a)(2)(c), (v) a Person that is not 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, or an estate or trust whose income from sources
without the United States is includible in gross income for federal income tax
purposes regardless of its connection with the conduct of a trade or business
within the United States, and (vi) any other Person so designated by the
Trustee based upon an Opinion of Counsel that the Transfer of an Ownership
Interest in a Class A-R Certificate to such Person may cause the Trust Fund to

                                                                  to EXHIBIT I


                       Section 5.02(c) of the Agreement

                  (c) Each Person who has or who acquires any Ownership
Interest in a Class A-R Certificate shall be deemed by the acceptance or
acquisition of such Ownership Interest to have agreed to be bound by the
following provisions, and the rights of each Person acquiring any Ownership
Interest in a Class A-R Certificate are expressly subject to the following
provisions:

                  (i) Each Person holding or acquiring any Ownership Interest
                  in a Class A-R Certificate shall be a Permitted Transferee
                  and shall promptly notify the Trustee of any change or
                  impending change in its status as a Permitted Transferee.

             (ii) No Ownership Interest in a Class A-R Certificate may be
         registered on the Closing Date or thereafter transferred, and the
         Trustee shall not register the Transfer of any Class A-R Certificate
         unless, in addition to the certificates required to be delivered to
         the Trustee under subparagraph (b) above, the Trustee shall have been
         furnished with an affidavit (a "Transfer Affidavit") of the initial
         owner or the proposed transferee in the form attached hereto as
         Exhibit I.

            (iii) Each Person holding or acquiring any Ownership Interest in a
         Class A-R Certificate shall agree (A) to obtain a Transfer Affidavit
         from any other Person to whom such Person attempts to Transfer its
         Ownership Interest in a Class A-R Certificate, (B) to obtain a
         Transfer Affidavit from any Person for whom such Person is acting as
         nominee, trustee or agent in connection with any Transfer of a Class
         A-R Certificate and (C) not to Transfer its Ownership Interest in a
         Class A-R Certificate or to cause the Transfer of an Ownership
         Interest in a Class A-R Certificate to any other Person if it has
         actual knowledge that such Person is not a Permitted Transferee.

             (iv) Any attempted or purported Transfer of any Ownership
         Interest in a Class A-R Certificate in violation of the provisions of
         this Section 5.02(c) shall be absolutely null and void and shall vest
         no rights in the purported Transferee. If any purported transferee
         shall become a Holder of a Class A-R Certificate in violation of the
         provisions of this Section 5.02(c), then the last preceding Permitted
         Transferee shall be restored to all rights as Holder thereof
         retroactive to the date of registration of Transfer of such Class A-R
         Certificate. The Trustee shall be under no liability to any Person
         for any registration of Transfer of a Class A-R Certificate that is
         in fact not permitted by Section 5.02(b) and this Section 5.02(c) or
         for making any payments due on such Certificate to the Holder thereof
         or taking any other action with respect to such Holder under the
         provisions of this Agreement so long as the Transfer was registered
         after receipt of the related Transfer Affidavit, Transferor
         Certificate and either the Rule 144A Letter or the Investment Letter.
         The Trustee shall be entitled but not obligated to recover from any
         Holder of a Class A-R Certificate that was in fact not a Permitted
         Transferee at the time it became a Holder or, at such subsequent time
         as it became other than a Permitted Transferee, all payments made on
         such Class A-R Certificate at and after either such time. Any such
         payments so recovered by the Trustee shall be paid and delivered by
         the Trustee to the last preceding Permitted Transferee of such
         Certificate.

                  (v) The Depositor shall use its best efforts to make
                  available, upon receipt of written request from the Trustee,
                  all information necessary to compute any tax imposed under
                  Section 860E(e) of the Code as a result of a Transfer of an
                  Ownership Interest in a Class A-R Certificate to any Holder
                  who is not a Permitted Transferee.
