                  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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                  Section 2.06.     Execution and Delivery of Certificates.

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

                  Section 2.07.     REMIC Matters.

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


                                  Article III

                          ADMINISTRATION AND SERVICING
                               OF MORTGAGE LOANS

                  Section 3.01. Master Servicer to Service Mortgage Loans.

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

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

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

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

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

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

                  Section 3.03.     Successor Servicers.

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

                  Section 3.04.     Liability of the Master Servicer.

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

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

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

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

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

                  Section 3.07.     Trustee to Act as Master Servicer.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                  (a)  The  Master   Servicer   may  from  time  to  time  make
withdrawals  from the Certificate  Account for the following  purposes but only
from funds related to the applicable Loan Group:

                      (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 each 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 1998 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 1998 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.

                  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)

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

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

                           reduced to zero; and

                           thereof have been reduced to zero.

                      (iv) to  each of the  Principal  Only  Certificates,  any
                  Class PO Deferred Amount for such Certificate Group, up to an
                  amount not to exceed the amount calculated pursuant to clause
                  (A)  of  the   definition  of  the   Subordinated   Principal

                  actually  received or  advanced  for such  Distribution  Date
                  (with  such  amount  to  be  allocated   first  from  amounts
                  calculated pursuant to (A)(i) and (ii) and then from (iii) of
                  the  definition  of   Subordinated   Principal   Distribution
                  Amount);

                      (v) to each  Class of  Subordinated  Certificates  in the
                  respective  Certificate Groups,  subject to paragraphs (a)(v)
                  and (d) below, in the following order of priority:

                  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 of Subordinated Certificates in the

                  thereof is reduced to zero;

                           (K) to the Class of Subordinated Certificates in the

                  amount  allocable  to  interest  equal to the  Class  Optimal

                           (L) to the Class of Subordinated Certificates in the
                  related  Certificate  Group  with a  designation  of "f",  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;

                      (vi)     notwithstanding the foregoing:

                           (A) If such Certificate Group is a Transferor Group,
                  the Current  Transfer  Payment shall not be  distributable to
                  the Lowest Class in such  Transferor  Group but shall instead
                  be   distributed  to  the  Lowest  Class  in  the  applicable
                  Transferee Group.

                           (B) If such Certificate Group is a Transferee Group,
                  the Current  Transfer Payment from the Transferor Group shall
                  be distributed as principal of the last Class of Certificates
                  then outstanding;  provided,  however,  that distributions in
                  respect of principal of any Class of  Certificates  shall not
                  exceed  the Class  Certificate  Balance  thereof  immediately
                  prior to such Distribution Date.

                           (C) amounts of interest and/or  principal  otherwise
                  payable to the then outstanding  Lowest Class in a Transferor
                  Group  will be  allocated  on a pro rata basis  between  such
                  Lowest Class and the related  Transfer Balance based upon the
                  related  Class  Certificate  Balance of such Lowest Class and
                  the outstanding  balance of the Transfer Balance  immediately
                  prior to such Distribution Date; and

                           (D) amounts of interest and/or  principal  allocated
                  to a Transfer  Balance for a  Certificate  Group  pursuant to
                  (v)(A) above will be paid to the last Class or Classes in the
                  related  Transferee  Group  as  additional   interest  and/or
                  principal (with amounts distributed as interest to be paid to
                  the last Classes in a Transferee  Group on a weighted average
                  basis); and

                      (vii)  to  the  Class  A-R  Certificates,  any  remaining
Available Funds.

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

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

                  (b) On each  Distribution  Date on and  prior to the  Accrual
Termination  Date,  the  Accrual  Amount for such  Distribution  Date shall not
(except as otherwise  provided in this  paragraph) be  distributed  as interest
with respect to the Class A-12  Certificates  but shall instead be added to the
Class Certificate Balance of such Class on the related  Distribution Date. With
respect to any Distribution  Date on and prior to the Accrual  Termination Date
on which  principal  payments on the Class A-11  Certificates  are  distributed
pursuant to Section  4.02(a)(iii),  the Accrual  Amount shall be deemed to have
been added on such  Distribution  Date to the Class  Certificate  Balance  (and
included  in the amount  distributable  on the  applicable  Accretion  Directed
Certificates  pursuant to Section  4.02(a)(ii) for such Distribution  Date) and
the  related  distribution  thereon  shall  be  deemed  to  have  been  applied
concurrently  towards the  reduction of all or a portion of the amount so added
and,  to  the  extent  of any  excess,  towards  the  reduction  of  the  Class
Certificate  Balance of the Class A-11  Certificates  immediately prior to such
Distribution Date.

                  (c) On each  Distribution  Date on or after the Senior Credit
Support Depletion Date for a Certificate Group,  notwithstanding the allocation
and  priority  set forth in Section  4.02(a)(iii)(x),  the portion of Available
Funds  available  to  be  distributed  to  the  Senior  Certificates  for  such
Certificate  Group  specified in such Section  will be  distributed  among such
Classes in such  Certificate  Group, pro rata, on the basis of their respective
Class  Certificate   Balances  (prior  to  making  any  distributions  on  such
Distribution Date) and until the Class Certificate Balances thereof are reduced
to zero.

                  (d) On each  Distribution  Date,  the amount  referred  to in
clause (i) of the definition of Class Optimal Interest  Distribution Amount for
such  Distribution  Date for each applicable Class of Certificates and Transfer
Balance shall be reduced by (i) the related  Class' and Transfer  Balance's pro
rata share (based on the applicable Class Optimal Interest  Distribution Amount
for each before  reduction  pursuant to this Section  4.02(d) of Net Prepayment
Interest  Shortfalls  for the related Loan Group,  and (ii) the related  Class'
Allocable Share of (A) after the Special Hazard Coverage Termination Date, with
respect to each  Mortgage  Loan in the related Loan Group 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
applicable   Bankruptcy  Coverage   Termination  Date,  with  respect  to  each
applicable  Mortgage  Loan in the related  Loan Group 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  for the related Loan
Group  incurred   during  the  calendar  month  preceding  the  month  of  such
Distribution Date and (D) after the applicable Fraud Loss Coverage  Termination
Date,  with respect to each Mortgage Loan in the related Loan Group 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  in the  related
Certificate Group which have a later  alphabetical  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 and related  Transfer
Balance,  if any (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  in  the  related
Certificate  Group having earlier  alphabetical  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)(v).

                  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 on the  Mortgage  Loans in a Loan Group 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
                  Principal Only Certificates of the related  Certificate Group
                  until the Class  Certificate  Balance  thereof  is reduced to
                  zero; and

                      (ii) (A) the applicable Non-PO Percentage of any Realized
                  Loss  (other than a Special  Hazard  Loss or an Excess  Loss)
                  shall be allocated  first,  to  Subordinated  Certificates of
                  such Certificate Group in reverse order of their alphabetical
                  Class designations (beginning with "f"), until the respective
                  Class  Certificate  Balance  of each such Class is reduced to
                  zero,  and  second,  to  the  Senior   Certificates  of  such
                  Certificate Group (other than the Principal Only Certificates
                  and the Notional Amount Certificates), pro rata, on the basis
                  of their  respective  Class  Certificate  Balances or, in the
                  case of any Accrual Certificates,  on the basis of the lesser
                  of their Class  Certificate  Balance and their  initial Class
                  Certificate  Balance,  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 Special
                  Hazard  Loss  (other  than a Special  Hazard Loss which is an
                  Excess  Loss) shall be allocated  first,  to the Lowest Class
                  outstanding,  regardless  of  Certificate  Group (if there is
                  more than one Class which is the Lowest  Class,  such Special
                  Hazard Loss,  other than an Excess Loss, will be allocated to
                  such Classes  concurrently  on a pro rata basis) in each case
                  until the Class  Certificate  Balances thereof are reduced to
                  zero, second, to the Senior  Certificates of such Certificate
                  Group (other than the related Principal Only Certificates and
                  the Notional Amount Certificates),  pro rata, on the basis of
                  their  respective  Class  Certificate  Balances  in each case
                  immediately prior to the related  Distribution Date until the
                  Class Certificate Balances thereof have been reduced to zero.

                           (C) the applicable  Non-PO  Percentage of any Excess
                  Losses shall be allocated  to the  Certificates  and Transfer
                  Balance,  if any, then outstanding in the related Certificate
                  Group,  pro  rata,  on the  basis of their  respective  Class
                  Certificate   Balances  (or,  in  the  case  of  any  Accrual
                  Certificates,  on the  basis  of  the  lesser  of  the  Class
                  Certificate Balance and the initial Class Certificate Balance
                  thereof)  and  related  Transfer   Balance,   as  applicable,
                  immediately prior to the related Distribution Date.

                  (b) Prior to the  occurrence of a Special  Hazard Loss in any
Loan Group,  if the sum of (i) the amount of any payments on the Principal Only
Certificates in the related  Certificate  Group in respect of Class PO Deferred
Amounts  and (ii) the  amount,  if any,  by which  the  aggregate  of the Class
Certificate  Balances  of all  outstanding  Classes  of  Certificates  in  such
Certificate Group (after giving effect to the distribution of principal and the
allocation  of  Realized   Losses  and  Class  PO  Deferred   Amounts  on  such
Distribution  Date) exceeds the aggregate of the Stated  Principal  Balances of
the  Mortgage  Loans in the related Loan Group for the  following  Distribution
Date, the Class Certificate  Balance of the Class of Subordinated  Certificates
then outstanding in the related  Certificate Group with the latest alphabetical
Class  designation  will be reduced by the amount of such excess.  On and after
the occurrence of a Special Hazard Loss in a Loan Group,  if the sum of (i) the
aggregate  of the Class  Certificate  Balances  of all  outstanding  Classes of
Certificates in both Certificate  Groups and (ii) the aggregate of all Transfer
Balances  outstanding (in each case after giving effect to the  distribution of
principal and the  allocation  of Realized  Losses on such  Distribution  Date)
exceeds the aggregate of the Stated Principal Balances of the Mortgage Loans in
both Loan Groups for the following  Distribution  Date,  the Class  Certificate
Balance of the Lowest Class  outstanding  (and any related  Transfer  Balance),
regardless  of  Certificate  Group will be reduced by the amount of such excess
(if there is more than one Class which is the Lowest Class, such excess will be
allocated to such Classes concurrently on a pro rata basis).

                  (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 and any  related  Transfer  Balance  in  proportion  to their  respective
Certificate Balances and Transfer Balance.

                  (d) Any allocation of Realized  Losses to a  Certificate,  to
any Component or to any Transfer  Balance or any  reduction in the  Certificate
Balance of a Certificate or of a Transfer  Balance  pursuant to Section 4.05(b)
shall be accomplished by reducing the Certificate Balance, Component Balance or
Transfer   Balance   thereof,   as   applicable,   immediately   following  the
distributions  made on the related  Distribution  Date in  accordance  with the
definition of "Certificate Balance," "Component Balance" or "Transfer 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 and the Depositor a statement  setting
forth with respect to the related distribution for each Certificate Group:

                      (i) the amount thereof allocable to principal, separately
                  identifying the aggregate amount of any Principal Prepayments
                  and Liquidation Proceeds included therein;

                      (ii) the amount thereof allocable to interest,  any Class
                  Unpaid 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

                  aggregate) with respect to such Distribution Date and related
                  Loan Group;

                      (viii)  the  Pass-Through  Rate  for each  such  Class of

                  Determination Date.

                  (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.
The  Trustee  will  send a copy of each  statement  provided  pursuant  to this
Section 4.06 to each Rating Agency.

                  (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.

                                   Article V

                                THE CERTIFICATES

                  Section 5.01.     The Certificates.

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

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

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

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

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

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

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

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

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

                  (b) No transfer of a Private Certificate shall be made unless
such transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable  state  securities laws or is exempt from the
registration requirements under said Act and such state securities laws. In the
event that a transfer  is to be made in  reliance  upon an  exemption  from the
Securities Act and such laws, in order to assure compliance with the Securities
Act and such laws, the  Certificateholder  desiring to effect such transfer and
such  Certificateholder's  prospective  transferee  shall  each  certify to the
Trustee in writing the facts surrounding the transfer in substantially the form
set forth in Exhibit J (the "Transferor  Certificate") and (i) deliver a letter
in  substantially  the form of either  Exhibit K (the  "Investment  Letter") or
Exhibit L (the "Rule 144A  Letter")  or (ii) there  shall be  delivered  to the
Trustee at the  expense  of the  transferor  an  Opinion  of Counsel  that such
transfer may be made  pursuant to an  exemption  from the  Securities  Act. The
Depositor  shall  provide  to any  Holder  of a  Private  Certificate  and  any
prospective transferee designated by any such Holder, information regarding the
related Certificates and the Mortgage Loans and such other information as shall
be  necessary  to  satisfy  the  condition  to  eligibility  set  forth in Rule
144A(d)(4) for transfer of any such Certificate  without  registration  thereof
under the Securities  Act pursuant to the  registration  exemption  provided by
Rule  144A.  The  Trustee  and the Master  Servicer  shall  cooperate  with the
Depositor in providing  the Rule 144A  information  referenced in the preceding
sentence,  including providing to the Depositor such information  regarding the
Certificates,  the Mortgage Loans and other matters regarding the Trust Fund as
the  Depositor  shall  reasonably  request  to meet its  obligation  under  the
preceding  sentence.  Each Holder of a Private  Certificate  desiring to effect
such transfer  shall,  and does hereby agree to,  indemnify the Trustee and the
Depositor,  the Seller and the Master  Servicer  against any liability that may
result if the transfer is not so exempt or is not made in accordance  with such
federal and state laws.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                  If  (a)  any  mutilated  Certificate  is  surrendered  to the
Trustee,   or  the  Trustee  receives  evidence  to  its  satisfaction  of  the
destruction, loss or theft of any Certificate and (b) there is delivered to the
Master  Servicer and the Trustee such  security or indemnity as may be required
by them to hold each of them  harmless,  then,  in the absence of notice to the
Trustee that such  Certificate has been acquired by a bona fide purchaser,  the
Trustee shall execute,  countersign and deliver,  in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of
like Class, tenor and Percentage  Interest.  In connection with the issuance of
any new  Certificate  under this  Section  5.03,  the  Trustee  may require the
payment of a sum sufficient to cover any tax or other governmental  charge that
may be imposed in relation  thereto and any other expenses  (including the fees
and expenses of the Trustee) connected therewith.  Any replacement  Certificate
issued pursuant to this Section 5.03 shall constitute complete and indefeasible
evidence of ownership, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

                  Section 5.04.     Persons Deemed Owners.

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

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

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

                  Section 5.06.     Maintenance of Office or Agency.

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

                     THE DEPOSITOR AND THE MASTER SERVICER

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

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

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

                  The Depositor and the Master  Servicer will each keep in full
effect its existence,  rights and franchises as a corporation under the laws of
the United States or under the laws of one of the states  thereof and will each
obtain and preserve its  qualification to do business as a foreign  corporation
in each  jurisdiction in which such  qualification  is or shall be necessary to
protect  the  validity  and  enforceability  of this  Agreement,  or any of the
Mortgage Loans and to perform its respective duties under this Agreement.

                  Any Person into which the  Depositor  or the Master  Servicer
may be merged or  consolidated,  or any  Person  resulting  from any  merger or
consolidation  to which the Depositor or the Master  Servicer shall be a party,
or any  person  succeeding  to the  business  of the  Depositor  or the  Master
Servicer,  shall be the successor of the Depositor or the Master  Servicer,  as
the case may be, hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties  hereto,  anything  herein to the
contrary  notwithstanding;  provided,  however, that the successor or surviving
Person to the Master Servicer shall be qualified to sell mortgage loans to, and
to service mortgage loans on behalf of, FNMA or FHLMC.

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

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

                  Section  6.04.   Limitation  on  Resignation  of  the  Master
Servicer.

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

                                    DEFAULT

                  Section 7.01. Events of Default.

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

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

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

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

                      (iv) the Master Servicer shall consent to the appointment
                  of a receiver or liquidator in any  insolvency,  readjustment
                  of debt,  marshalling  of assets and  liabilities  or similar
                  proceedings  of or relating to the Master  Servicer or all or
                  substantially all of the property of the Master Servicer; or

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

                  If an Event of Default  described  in  clauses  (i) to (v) of
this Section 7.01 shall occur,  then,  and in each and every such case, so long
as such Event of Default shall not have been  remedied,  the Trustee may, or at
the direction of the Holders of Certificates evidencing not less  than  66-2/3%
of the Voting Rights evidenced by the Certificates, the Trustee shall by notice
in  writing  to the  Master  Servicer  (with  a copy to  each  Rating  Agency),
terminate all of the rights and  obligations of the Master  Servicer under this
Agreement and in and to the Mortgage Loans and the proceeds thereof, other than
its rights as a  Certificateholder  hereunder.  On and after the receipt by the
Master Servicer of such written  notice,  all authority and power of the Master
Servicer  hereunder,  whether with respect to the Mortgage  Loans or otherwise,
shall pass to and be vested in the Trustee.  The Trustee shall make any Advance
which the Master  Servicer  failed to make subject to Section 3.04,  whether or
not the  obligations of the Master  Servicer have been  terminated  pursuant to
this  Section.  The Trustee is hereby  authorized  and empowered to execute and
deliver,  on behalf of the Master Servicer,  as  attorney-in-fact or otherwise,
any and all documents and other instruments,  and to do or accomplish all other
acts or things  necessary or  appropriate to effect the purposes of such notice
of termination,  whether to complete the transfer and endorsement or assignment
of the Mortgage Loans and related  documents,  or otherwise.  Unless  expressly
provided  in  such  written  notice,  no  such  termination  shall  affect  any
obligation of the Master Servicer to pay amounts owed pursuant to Article VIII.
The Master  Servicer  agrees to  cooperate  with the Trustee in  effecting  the
termination of the Master  Servicer's  responsibilities  and rights  hereunder,
including,  without limitation, the transfer to the Trustee of all cash amounts
which shall at the time be credited to the Certificate  Account,  or thereafter
be received with respect to the Mortgage Loans.

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

                  Section 7.02.     Trustee to Act; Appointment of Successor.

                  On and after the time the Master  Servicer  receives a notice
of termination  pursuant to Section 7.01, the Trustee shall,  subject to and to
the extent provided in Section 3.07, be the successor to the Master Servicer in
its capacity as master servicer under this Agreement and the  transactions  set
forth or provided for herein and shall be subject to all the  responsibilities,
duties and  liabilities  relating  thereto placed on the Master Servicer by the
terms and provisions hereof and applicable law including the obligation to make
Advances pursuant to Section 4.01. As compensation  therefor, the Trustee shall
be  entitled  to all funds  relating  to the  Mortgage  Loans  that the  Master
Servicer  would  have been  entitled  to charge to the  Certificate  Account or
Distribution  Account if the Master  Servicer had  continued to act  hereunder.
Notwithstanding  the foregoing,  if the Trustee has become the successor to the
Master  Servicer in accordance  with Section 7.01, the Trustee may, if it shall
be unwilling to so act, or shall,  if it is prohibited  by applicable  law from
making  Advances  pursuant to Section 4.01 or if it is  otherwise  unable to so
act,  appoint,  or petition a court of competent  jurisdiction to appoint,  any
established  mortgage loan servicing  institution the appointment of which does
not adversely affect the then current rating of the Certificates by each Rating
Agency, as the successor to the Master Servicer  hereunder in the assumption of
all or any part of the  responsibilities,  duties or  liabilities of the Master
Servicer  hereunder.   Any  successor  to  the  Master  Servicer  shall  be  an
institution  which  is a  FNMA  and  FHLMC  approved  seller/servicer  in  good
standing,  which has a net worth of at least  $15,000,000,  which is willing to
service the Mortgage Loans and which executes and delivers to the Depositor and
the Trustee an agreement  accepting such delegation and assignment,  containing
an assumption by such Person of the rights, powers,  duties,  responsibilities,
obligations and  liabilities of the Master Servicer (other than  liabilities of
the Master  Servicer  under Section 6.03 incurred  prior to  termination of the
Master Servicer under Section 7.01), with like effect as if originally named as
a party to this Agreement;  provided that each Rating Agency  acknowledges that
its rating of the Certificates in effect  immediately  prior to such assignment
and delegation  will not be qualified or reduced as a result of such assignment
and  delegation.  Pending  appointment  of a successor  to the Master  Servicer
hereunder, the Trustee, unless the Trustee is prohibited by law from so acting,
shall,  subject to Section 3.07, act in such capacity as hereinabove  provided.
In connection with such  appointment and assumption,  the Trustee may make such
arrangements for the compensation of such successor out of payments on Mortgage
Loans as it and such successor  shall agree;  provided,  however,  that no such
compensation  shall be in excess of the  Master  Servicing  Fee  permitted  the
Master  Servicer  hereunder.  The  Trustee and such  successor  shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such  succession.  Neither the Trustee nor any other successor  master servicer
shall be deemed to be in default hereunder by reason of any failure to make, or
any delay in making,  any distribution  hereunder or any portion thereof or any
failure to perform, or any delay in performing,  any duties or responsibilities
hereunder,  in either  case  caused by the  failure of the Master  Servicer  to
deliver  or  provide,  or any  delay in  delivering  or  providing,  any  cash,
information, documents or records to it.

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

                  Section 7.03.     Notification to Certificateholders.

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

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

                                  Article VIII

                             CONCERNING THE TRUSTEE

                  Section 8.01.     Duties of the Trustee.

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

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

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

                      (i) unless an Event of Default known to the Trustee shall
                  have occurred and be continuing,  the duties and  obligations
                  of the  Trustee  shall be  determined  solely by the  express
                  provisions of this Agreement, the Trustee shall not be liable
                  except for the  performance of such duties and obligations as
                  are  specifically  set forth in this  Agreement,  no  implied
                  covenants or  obligations  shall be read into this  Agreement
                  against the Trustee and the Trustee may conclusively rely, as
                  to the truth of the  statements  and the  correctness  of the
                  opinions expressed therein, upon any certificates or opinions
                  furnished to the Trustee and  conforming to the  requirements
                  of this  Agreement  which  it  believed  in good  faith to be
                  genuine  and  to  have  been  duly  executed  by  the  proper
                  authorities respecting any matters arising hereunder;

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

                      (iii) the Trustee shall not be liable with respect to any
                  action  taken,  suffered or omitted to be taken by it in good
                  faith  in  accordance   with  the  direction  of  Holders  of
                  Certificates  evidencing  not  less  than  25% of the  Voting
                  Rights of Certificates relating to the time, method and place
                  of conducting any proceeding for any remedy  available to the
                  Trustee,  or exercising any trust or power conferred upon the
                  Trustee under this Agreement.

                  Section 8.02.     Certain Matters Affecting the Trustee.

                  Except as otherwise provided in Section 8.01:

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

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

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

                      (iv)  the  Trustee   shall  not  be  bound  to  make  any
                  investigation  into  the  facts  or  matters  stated  in  any
                  resolution,   certificate,  statement,  instrument,  opinion,
                  report, notice,  request,  consent,  order, approval, bond or
                  other paper or document, unless requested in writing so to do
                  by Holders of  Certificates  evidencing  not less than 25% of
                  the Voting Rights allocated to each Class of Certificates;

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

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

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

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

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

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

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

                  Section 8.04. Trustee May Own Certificates.

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

                  Section 8.05. Trustee's Fees and Expenses.

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

                  Section 8.06.     Eligibility Requirements for the Trustee.

                  The Trustee  hereunder shall at all times be a corporation or
association  organized  and  doing  business  under  the laws of a state or the
United  States of America,  authorized  under such laws to  exercise  corporate
trust powers,  having a combined  capital and surplus of at least  $50,000,000,
subject to supervision or examination by federal or state  authority and with a
credit  rating  which would not cause  either of the Rating  Agencies to reduce
their  respective then current ratings of the  Certificates (or having provided
such security  from time to time as is  sufficient to avoid such  reduction) as
evidenced in writing by each Rating Agency.  If such corporation or association
publishes  reports of  condition at least  annually,  pursuant to law or to the
requirements of the aforesaid supervising or examining authority,  then for the
purposes  of this  Section  8.06  the  combined  capital  and  surplus  of such
corporation  or  association  shall be deemed to be its  combined  capital  and
surplus as set forth in its most recent  report of condition so  published.  In
case at any time the Trustee shall cease to be eligible in accordance  with the
provisions of this Section 8.06,  the Trustee shall resign  immediately  in the
manner and with the effect  specified in Section  8.07.  The entity  serving as
Trustee may have normal banking and trust  relationships with the Depositor and
its affiliates or the Master  Servicer and its affiliates;  provided,  however,
that such entity  cannot be an  affiliate of the Seller,  the  Depositor or the
Master  Servicer  other than the Trustee in its role as successor to the Master
Servicer.

                  Section 8.07.     Resignation and Removal of the Trustee.

                  The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice of resignation to the Depositor,
the Master  Servicer  and each  Rating  Agency not less than 60 days before the
date specified in such notice,  when, subject to Section 8.08, such resignation
is to take effect,  and  acceptance by a successor  trustee in accordance  with
Section  8.08  meeting  the  qualifications  set forth in Section  8.06.  If no
successor trustee meeting such qualifications  shall have been so appointed and
have  accepted  appointment  within 30 days after the giving of such  notice or
resignation,  the  resigning  Trustee  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor trustee.

                  If at any time the  Trustee  shall  cease to be  eligible  in
accordance  with the  provisions of Section 8.06 and shall fail to resign after
written request  thereto by the Depositor,  or if at any time the Trustee shall
become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a
receiver of the Trustee or of its property  shall be  appointed,  or any public
officer  shall  take  charge or control of the  Trustee or of its  property  or
affairs for the purpose of  rehabilitation,  conservation or liquidation,  or a
tax is imposed with respect to the Trust Fund by any state in which the Trustee
or the Trust Fund is located and the imposition of such tax would be avoided by
the  appointment  of a  different  trustee,  then the  Depositor  or the Master
Servicer  may remove the Trustee  and  appoint a  successor  trustee by written
instrument, in triplicate, one copy of which shall be delivered to the Trustee,
one copy to the Master Servicer and one copy to the successor trustee.

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

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

                  Section 8.08.     Successor Trustee.

                  Any successor  trustee  appointed as provided in Section 8.07
shall execute,  acknowledge and deliver to the Depositor and to its predecessor
trustee  and the Master  Servicer  an  instrument  accepting  such  appointment
hereunder and thereupon the resignation or removal of the  predecessor  trustee
shall become  effective and such  successor  trustee,  without any further act,
deed or  conveyance,  shall become  fully  vested with all the rights,  powers,
duties and obligations of its predecessor hereunder, with the like effect as if
originally named as trustee herein. The Depositor,  the Master Servicer and the
predecessor  trustee  shall  execute and deliver such  instruments  and do such
other things as may reasonably be required for more fully and certainly vesting
and confirming in the successor trustee all such rights,  powers,  duties,  and
obligations.

                  No successor trustee shall accept  appointment as provided in
this Section 8.08 unless at the time of such acceptance such successor  trustee
shall be eligible  under the  provisions  of Section  8.06 and its  appointment
shall not adversely affect the then current rating of the Certificates.

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

                  Section 8.09.     Merger or Consolidation of the Trustee.

                  Any  corporation  into  which  the  Trustee  may be merged or
converted or with which it may be  consolidated  or any  corporation  resulting
from any merger,  conversion or  consolidation  to which the Trustee shall be a
party, or any corporation  succeeding to the business of the Trustee,  shall be
the successor of the Trustee hereunder, provided that such corporation shall be
eligible  under the  provisions of Section 8.06 without the execution or filing
of any paper or further act on the part of any of the parties hereto,  anything
herein to the contrary notwithstanding.

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

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

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

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

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

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

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

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

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

                  Section 8.11.     Tax Matters.

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

                  In order to enable the  Trustee to perform  its duties as set
forth herein,  the Depositor  shall  provide,  or cause to be provided,  to the
Trustee  within ten (10) days after the Closing  Date all  information  or data
that the  Trustee  requests in writing and  determines  to be relevant  for tax
purposes to the valuations and offering prices of the Certificates,  including,
without limitation,  the price, yield, prepayment assumption and projected cash
flows of the  Certificates  and the Mortgage Loans.  Thereafter,  the Depositor
shall provide to the Trustee  promptly upon written  request  therefor any such
additional  information  or data  that  the  Trustee  may,  from  time to time,
reasonably  request in order to enable the Trustee to perform its duties as set
forth herein.  The  Depositor  hereby  indemnifies  the Trustee for any losses,
liabilities, damages, claims or expenses of the Trustee arising from any errors
or miscalculations of the Trustee that result from any failure of the Depositor
to provide,  or to cause to be provided,  accurate  information  or data to the
Trustee on a timely basis.

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

                  Section 8.12.     Periodic Filings.

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

                                  TERMINATION

                  Section 9.01. Termination upon Liquidation or Purchase of the
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 related  Loan Group at the price equal to the sum of (i) 100% of the Stated
Principal  Balance  of each  Mortgage  Loan in such Loan Group  (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 in such Loan Group 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 in such Loan Group 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 repurchase
all Mortgage  Loans and REO  Properties in a Loan Group  pursuant to clause (a)
above shall be conditioned upon the aggregate  Stated Principal  Balance of the
Mortgage  Loans  in  such  Loan  Group,  at the  time of any  such  repurchase,
aggregating  less then ten  percent of the  aggregate  Cut-off  Date  Principal
Balance of the Mortgage Loans in such Loan Group.

                  Section 9.02.     Final Distribution on the Certificates.

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

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

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

                  Upon  presentation  and  surrender of the  Certificates,  the
Trustee shall cause to be distributed to the  Certificateholders of each Class,
in each  case on the  final  Distribution  Date and in the  order  set forth in
Section  4.02,  in the case of the  Certificateholders,  in proportion to their
respective Percentage Interests, with respect to Certificateholders of the same
Class,  an amount  equal to (i) as to each Class of Regular  Certificates,  the
Certificate  Balance  thereof  plus (a) accrued  interest  thereon (or on their
Notional Amount, if applicable) in the case of an interest-bearing Certificate,
and (b) any  Class  PO  Deferred  Amounts  in the  case of the  Principal  Only
Certificates  allocated  to  such  Certificate,   (ii)  as  to  each  Class  of
Certificates,  any related  Transfer  Balance and accrued  interest thereon and
(iii) 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  with  respect  to the  Mortgage  Loans in a Loan Group as  provided  in
Section 9.01 at such time as the Mortgage  Loans in the other Loan Group are no
longer part of the Trust Fund, 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"  either 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.

                                   Article X

                            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

                  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;

report described in Section 3.17; and

                  4. Any notice of a purchase  of a Mortgage  Loan  pursuant to
Section 2.02, 2.03 or 3.11.

                  (b) All directions, demands and notices hereunder shall be in

Master  Servicer,  and (d) in the  case of each  of the  Rating  Agencies,  the
address specified therefor in the definition  corresponding to the name of such
Rating Agency. Notices to Certificateholders shall be deemed given when mailed,
first class postage  prepaid,  to their respective  addresses  appearing in the
Certificate Register.

                  Section 10.06.    Severability of Provisions.

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

                  Section 10.07.    Assignment.

                  Notwithstanding  anything to the contrary  contained  herein,
except as provided in Section 6.02,  this  Agreement may not be assigned by the
Master Servicer without the prior written consent of the Trustee and Depositor.

                  Section 10.08.    Limitation on Rights of Certificateholders.

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

                  No Certificateholder  shall have any right to vote (except as
provided  herein)  or  in  any  manner  otherwise  control  the  operation  and
management of the Trust Fund, or the  obligations  of the parties  hereto,  nor
shall anything  herein set forth or contained in the terms of the  Certificates
be construed so as to constitute  the  Certificateholders  from time to time as
partners or members of an association; nor shall any Certificateholder be under
any  liability  to any third party by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.

                  No  Certificateholder  shall  have any  right by virtue or by
availing  itself of any  provisions  of this  Agreement to institute  any suit,
action or  proceeding in equity or at law upon or under or with respect to this
Agreement,  unless  such  Holder  previously  shall have given to the Trustee a
written notice of an Event of Default and of the continuance thereof, as herein
provided,  and unless the Holders of Certificates  evidencing not less than 25%
of the Voting Rights evidenced by the Certificates shall also have made written
request to the Trustee to institute such action,  suit or proceeding in its own
name as Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs,  expenses, and liabilities to be
incurred therein or thereby,  and the Trustee, for 60 days after its receipt of
such notice,  request and offer of indemnity shall have neglected or refused to
institute  any  such  action,  suit or  proceeding;  it  being  understood  and
intended,  and being expressly covenanted by each  Certificateholder with every
other  Certificateholder  and  the  Trustee,  that no one or  more  Holders  of
Certificates  shall  have any  right in any  manner  whatever  by  virtue or by
availing  itself or themselves of any  provisions of this  Agreement to affect,
disturb  or  prejudice   the  rights  of  the  Holders  of  any  other  of  the
Certificates, or to obtain or seek to obtain priority over or preference to any
other such Holder or to enforce any right under this  Agreement,  except in the
manner herein  provided and for the common  benefit of all  Certificateholders.
For the  protection  and  enforcement  of the provisions of this Section 10.08,
each and every  Certificateholder  and the  Trustee  shall be  entitled to such
relief as can be given either at law or in equity.

                  Section 10.09.    Inspection and Audit Rights.

                  The Master Servicer agrees that, on reasonable  prior notice,
it will permit and will cause each Subservicer to permit any  representative of
the  Depositor  or the Trustee  during the Master  Servicer's  normal  business
hours, to examine all the books of account,  records,  reports and other papers
of the Master  Servicer  relating  to the  Mortgage  Loans,  to make copies and
extracts therefrom,  to cause such books to be audited by independent certified
public accountants  selected by the Depositor or the Trustee and to discuss its
affairs,  finances  and  accounts  relating  to the  Mortgage  Loans  with  its
officers,  employees and independent  public accountants (and by this provision
the Master  Servicer hereby  authorizes  said  accountants to discuss with such
representative  such affairs,  finances and accounts),  all at such  reasonable
times and as often as may be reasonably  requested.  Any out-of-pocket  expense
incident  to the  exercise by the  Depositor  or the Trustee of any right under
this Section 10.09 shall be borne by the party requesting such inspection;  all
other  such  expenses  shall be borne by the  Master  Servicer  or the  related
Subservicer.

                  Section 10.10.    Certificates Nonassessable and Fully Paid.

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

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

         with the terms thereof.

                            (2)  IndyMac  has  the  full  corporate  power  and

         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

         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.

            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

                           (1) The  information  set forth on Schedule I to the

         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 0.32% of the Mortgage Loans in Loan
         Group 1 (by aggregate Stated Principal Balance) are Cooperative Loans.
         No more than 0.18% of the Mortgage Loans in Loan Group 2 (by aggregate
         Stated Principal Balance) 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.

Initial Certificate Balances of the denominations of all Certificates of the
Class to which this Certificate belongs) in certain monthly distributions with
respect to a Trust Fund consisting primarily of the Mortgage Loans deposited
by CWMBS, Inc. (the "Depositor"). The Trust Fund was created pursuant to a
Pooling and Servicing Agreement dated as of the Cut-off Date specified above
(the "Agreement") among the Depositor, IndyMac, Inc., as seller (in such
capacity, the "Seller"), and as master servicer (in such capacity, the "Master
Servicer"), and The Bank of New York, as trustee (the "Trustee"). To the
extent not defined herein, the capitalized terms used herein have the meanings
assigned in the Agreement. This Certificate is issued under and is subject to
the terms, provisions and conditions of the Agreement, to which Agreement the
Holder of this Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound.

         [No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under said Act and such laws. In the event that a
transfer is to be made in reliance upon an exemption from the Securities Act
and such laws, in order to assure compliance with the Securities Act and such
laws, the Certificateholder desiring to effect such transfer and such
Certificateholder's prospective transferee shall each certify to the Trustee
in writing the facts surrounding the transfer. In the event that such a
transfer is to be made within three years from the date of the initial
issuance of Certificates pursuant hereto, there shall also be delivered
(except in the case of a transfer pursuant to Rule 144A of the Securities Act)
to the Trustee an Opinion of Counsel that such transfer may be made pursuant
to an exemption from the Securities Act and such state securities laws, which
Opinion of Counsel shall not be obtained at the expense of the Trustee, the
Seller, the Master Servicer or the Depositor. The Holder hereof desiring to
effect such transfer shall, and does hereby agree to, indemnify the Trustee
and the Depositor 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 a Certificate of this Class shall be made unless the
Trustee shall have received either (i) a representation [letter] from the
transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Trustee, to the effect that such transferee is not an
employee benefit plan subject to Section 406 of ERISA or Section 4975 of the
Code, nor a person acting on behalf of any such plan, which representation
letter shall not be an expense of the Trustee or the Master Servicer, (ii) if
the purchaser is an insurance company, a representation that the purchaser is
an insurance company which is purchasing such Certificates with funds
contained in an "insurance company general account" (as such term is defined
in Section V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE
95-60")) and that the purchase and holding of such Certificates are covered
under PTCE 95-60 or (iii) in the case of any such Certificate presented for
registration in the name of an employee benefit plan subject to ERISA or
Section 4975 of the Code (or comparable provisions of any subsequent
enactments), or a trustee of any such plan or any other person acting on
behalf of any such plan, an Opinion of Counsel satisfactory to the Trustee and
the Master Servicer to the effect that the purchase or holding of such
Certificate will not result in the assets of the Trust Fund being deemed to be
"plan assets" and subject to the prohibited transaction provisions of ERISA
and the Code and will not subject the Trustee to any obligation in addition to
those undertaken in the Agreement, which Opinion of Counsel shall not be an
expense of the Trustee or the Master Servicer. [Such representation shall be
deemed to have been made to the Trustee by the Transferee's acceptance of a
Certificate of this Class and by a beneficial owner's acceptance of its
interest in a Certificate of this Class.] Notwithstanding anything else to the
contrary herein, any purported transfer of a Certificate of this Class to or
on behalf of an employee benefit plan subject to ERISA or to the Code without
the opinion of counsel satisfactory to the Trustee as described above shall be
void and of no effect.

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

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

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

                      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
Trustee based upon an Opinion of Counsel that the Transfer of an Ownership
Interest in a Class A-R Certificate to such Person may cause the Trust Fund to

                       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.
