                        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
Depositor,  without recourse,  all the right, title and interest of the Seller
in and to the Mortgage Loans, including all interest and principal received or
receivable  by the Seller on or with respect to the  Mortgage  Loans after the
Cut-off  Date and all interest and  principal  payments on the Mortgage  Loans
received prior to the Cut-off Date in respect of  installments of interest and
principal due thereafter, but not including payments of principal and interest
due and payable on the  Mortgage  Loans on or before the Cut-off  Date.  On or
prior to the Closing  Date,  the Seller shall  deliver to the Depositor or, at
the Depositor's direction,  to the Trustee or other designee of the Depositor,
the Mortgage File for each Mortgage Loan listed in the Mortgage Loan Schedule.
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,
written assurance or substitution agreement, if any;

          (v) except as provided  below,  the original or  duplicate  original
lender's title policy and all riders thereto; and

          (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

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

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.

                         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.

          (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.

                               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) On each  Distribution  Date,  the  Trustee  shall  withdraw  the
Available  Funds  from  the  Distribution  Account  and  apply  such  funds to
distributions  on the 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 related  Class  Optimal
          Interest Distribution Amount, any shortfall being allocated pro rata
          among such Classes in  proportion to the amount of the Class Optimal
          Interest Distribution Amount that would have been distributed in the
          absence of such shortfall;

               (ii) to each  Class  of  Senior  Certificates  concurrently  as
          follows:

                    (x) to the Class PO  Certificates  an amount  allocable to
               principal equal to the PO Formula  Principal  Amount, up to the
               outstanding   Class   Certificate   Balance  of  the  Class  PO
               Certificates;

                    (y) on each  Distribution  Date prior to the Senior Credit
               Support Depletion Date, the Non-PO Formula Principal Amount, up
               to the amount of the Senior Principal  Distribution  Amount for
               such Distribution Date, will be distributed,  sequentially,  to
               the Class A-R and Class A-1 Certificates,  in that order, until
               the Class  Certificate  Balances  thereof  have been reduced to
               zero;

               (iii) to the  Class PO  Certificates  an  amount  allocable  to
principal  equal to the PO Formula  Principal  Amount,  up to the  outstanding
Class Certificate Balance of the Class PO Certificates;

               (iv) to each  Class of  Subordinated  Certificates,  subject to
paragraph (e) below, in the following order of priority:

                    (A) to the Class B-1 Certificates,  an amount allocable to
interest  equal to the Class  Optimal  Interest  Distribution  Amount for such
Class for such Distribution Date;

                    (B) to the Class B-1 Certificates,  an amount allocable to
principal  equal to its Pro Rata  Share for such  Distribution  Date until the
Class Certificate Balance thereof is reduced to zero;

                    (C) to the Class B-2 Certificates,  an amount allocable to
interest  equal to the Class  Optimal  Interest  Distribution  Amount for such
Class for such Distribution Date;

                    (D) to the Class B-2 Certificates,  an amount allocable to
principal  equal to its Pro Rata  Share for such  Distribution  Date until the
Class Certificate Balance thereof is reduced to zero;

                    (E) to the Class B-3 Certificates,  an amount allocable to
interest  equal to the Class  Optimal  Interest  Distribution  Amount for such
Class for such Distribution Date;

                    (F) to the Class B-3 Certificates,  an amount allocable to
principal  equal to its Pro Rata  Share for such  Distribution  Date until the
Class Certificate Balance thereof is reduced to zero;

                    (G) to the Class B-4 Certificates,  an amount allocable to
interest  equal to the Class  Optimal  Interest  Distribution  Amount for such
Class for such Distribution Date;

                    (H) to the Class B-4 Certificates,  an amount allocable to
principal  equal to its Pro Rata  Share for such  Distribution  Date until the
Class Certificate Balance thereof is reduced to zero;

                    (I) to the Class B-5 Certificates,  an amount allocable to
interest  equal to the Class  Optimal  Interest  Distribution  Amount for such
Class for such Distribution Date;

                    (J) to the Class B-5 Certificates,  an amount allocable to
principal  equal to its Pro Rata  Share for such  Distribution  Date until the
Class Certificate Balance thereof is reduced to zero;

                    (K) to the Class B-6 Certificates,  an amount allocable to
interest  equal to the Class  Optimal  Interest  Distribution  Amount for such
Class for such Distribution Date; and

                    (L) to the Class B-6 Certificates,  an amount allocable to
principal  equal to its Pro Rata  Share for such  Distribution  Date until the
Class Certificate Balance thereof is reduced to zero; and

               (v) to the Class A-R Certificates, any remaining funds.

          On any Distribution Date, amounts distributed in respect of Class PO
Deferred Amounts will not reduce the Class Certificate Balance of the Class PO
Certificates.

          On any  Distribution  Date,  to the extent the Amount  Available for
Senior Principal is insufficient to make the full distribution  required to be
made pursuant to clause (iii)(x) above,  (A) the amount  distributable  on the
Class PO Certificates in respect of principal shall be equal to the product of
(1)  the  Amount  Available  for  Senior  Principal  and (2) a  fraction,  the
numerator of which is the PO Formula  Principal  Amount and the denominator of
which is the sum of the PO Formula  Principal  Amount and the Senior Principal
Distribution   Amount  and  (B)  the  amount   distributable   on  the  Senior
Certificates,  other than the Class PO  Certificates,  in respect of principal
shall be equal to the product of (1) the Amount Available for Senior Principal
and  (2)  a  fraction,   the  numerator  of  which  is  the  Senior  Principal
Distribution  Amount  and the  denominator  of which is the sum of the  Senior
Principal Distribution Amount and the PO Formula Principal Amount.

          (b) [Reserved];

          (c) On each  Distribution Date on or after the Senior Credit Support
Depletion  Date,  notwithstanding  the  allocation  and  priority set forth in
Section  4.02(a)(ii)(y),  the  portion  of  Available  Funds  available  to be
distributed as principal of the Senior  Certificates  (other than the Class PO
Certificates)  shall  be  distributed  concurrently,  as  principal,  on  such
Classes,  pro  rata,  on the  basis  of  their  respective  Class  Certificate
Balances, until the Class Certificate Balances thereof are reduced to zero.

          (d) On each Distribution  Date, the amount referred to in clause (i)
of the definition of Class Optimal Interest Distribution Amount for each Class
of Certificates for such Distribution Date shall be reduced by (i) the related
Class'  pro rata share of Net  Prepayment  Interest  Shortfalls  based on such
Class' Optimal Interest Distribution Amount for such Distribution Date without
taking into  account  such Net  Prepayment  Interest  Shortfalls  and (ii) the
related  Class'  Allocable  Share of (A) after  the  Special  Hazard  Coverage
Termination  Date,  with respect to each  Mortgage  Loan that became a Special
Hazard  Mortgage  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  Termination Date, with respect to each Mortgage Loan that
became subject to a Bankruptcy  Loss during the calendar  month  preceding the
month of such  Distribution  Date,  the  interest  portion of the related Debt
Service  Reduction  or  Deficient  Valuation,  (C) each  Relief Act  Reduction
incurred  during the calendar month  preceding the month of such  Distribution
Date and (D) after the Fraud Coverage  Termination  Date, with respect to each
Mortgage Loan that became a Fraud 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.

          (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)(iv).

     Section 4.03.      [Reserved]

     Section 4.04.     [Reserved]

     Section 4.05.     Allocation of Realized Losses.

          (a) On or  prior  to each  Determination  Date,  the  Trustee  shall
determine the total amount of Realized Losses,  including Excess Losses,  with
respect to the related Distribution Date.

          Realized  Losses  with  respect  to any  Distribution  Date shall be
allocated as follows:

               (i)  the   applicable  PO  Percentage  of  any  Realized  Loss,
including  any Excess Loss,  shall be  allocated to the Class PO  Certificates
until the Class Certificate Balance thereof is reduced to zero; and

               (ii) (A) the applicable  Non-PO Percentage of any Realized Loss
(other than an Excess  Loss) shall be  allocated  first,  to the  Subordinated
Certificates   in  reverse   order  of  their   respective   numerical   Class
designations,  until the  respective  Class  Certificate  Balance of each such
Class is reduced to zero and second,  to the Senior  Certificates  (other than
the  Class PO and  Class X  Certificates),  pro  rata,  on the  basis of their
respective Class Certificate  Balances,  in each case immediately prior to the
related  Distribution Date, until the respective Class Certificate  Balance of
each such Class is reduced to zero;

                    (B) the applicable  Non-PO Percentage of any Excess Losses
on the Mortgage Loans shall be allocated to the Classes of Senior Certificates
(other  than  the  Class PO and  Class X  Certificates)  and the  Subordinated
Certificates  then  outstanding,  pro rata,  on the basis of their  respective
Class Certificate Balances in each case until the respective Class Certificate
Balances thereof have been reduced to zero.

          (b) The  Class  Certificate  Balance  of the  Class of  Subordinated
Certificates  then  outstanding with the highest  numerical Class  designation
shall be reduced on each Distribution Date by the amount, if any, by which the
aggregate  of the Class  Certificate  Balances of all  outstanding  Classes of
Certificates  exceeds the Pool  Stated  Principal  Balance  for the  following
Distribution Date.

          (c) Any Realized Loss  allocated to a Class of  Certificates  or any
reduction in the Class Certificate Balance of a Class of Certificates pursuant
to Section 4.05(b) shall be allocated among the  Certificates of such Class in
proportion to their respective Certificate Balances.

          (d) Any  allocation of Realized  Losses to a  Certificate  or to any
Component  or  any  reduction  in the  Certificate  Balance  of a  Certificate
pursuant to Section  4.05(b) shall be accomplished by reducing the Certificate
Balance or Component Balance thereof, as applicable, immediately following the
distributions  made on the related  Distribution  Date in accordance  with the
definition of  "Certificate  Balance" or "Component  Balance," as the case may
be.

     Section 4.06.     Monthly Statements to Certificateholders.

          (a) Not later than each Distribution Date, the Trustee shall prepare
and cause to be forwarded by first class mail to each  Certificateholder,  the
Master  Servicer,  the Depositor  and each Rating  Agency a statement  setting
forth with respect to the related distribution:

               (i) the  amount  thereof  allocable  to  principal,  separately

          Interest  Shortfall  included in such distribution and any remaining
          Class  Unpaid  Interest   Shortfall  after  giving  effect  to  such
          distribution;

               (iii)  if the  distribution  to the  Holders  of such  Class of
          Certificates   is  less  than  the  full   amount   that   would  be
          distributable  to  such  Holders  if  there  were  sufficient  funds
          available  therefor,  the amount of the shortfall and the allocation
          thereof  as  between   principal  and   interest;

               (iv)  the  Class   Certificate   Balance   of  each   Class  of
          Certificates after giving effect to the distribution of principal on
          such Distribution Date;

               (v)  the  Pool  Stated  Principal  Balance  for  the  following

               (x) the  number and  aggregate  principal  amounts of  Mortgage

          (1) 1 to 30 days  (2) 31 to 60 days  (3) 61 to 90 days and (4) 91 or

          month and (B) delinquent 60 days or more on each of the Due Dates in

               (xiii)  the  total  number  and  principal  balance  of any REO

               (xiv)  the  Senior  Prepayment  Percentage  for  the  following

          (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  and the  ERISA-Restricted  Certificate  is a  Residual
Certificate or a Subordinated Certificate, 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 1.02.     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 1.03.     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.

                            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 any 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's 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.

          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
assigned to the Trustee for the benefit of the Certificateholders.

     Section 10.05.    Notices.

          (a) The  Trustee  shall use its best  efforts  to  promptly  provide
notice to each Rating Agency with respect to each of the following of which it
has actual knowledge:

          1. Any material change or amendment to this Agreement;

          2. The occurrence of any Event of Default that has not been cured;

          3. The  resignation  or  termination  of the Master  Servicer or the
     Trustee and the appointment of any successor;

          4. The  repurchase or  substitution  of Mortgage  Loans  pursuant to
     Section 2.03; and

          5. The final payment to Certificateholders.

          In  addition,  the  Trustee  shall  promptly  furnish to each Rating
     Agency copies of the following:

               1. Each report to Certificateholders described in Section 4.06;

               2. Each annual statement as to compliance  described in Section
     3.16;

               3. Each annual independent public accountants' servicing report
     described in Section 3.17; and

         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
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) 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-O


            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  0.60% of the  Mortgage  Loans (by  aggregate
     Stated Principal Balance of the Mortgage Loans) 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

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

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

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

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

                       [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.

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.

                           *        *        *

                              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

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

                       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.
