          THIS  POOLING  AND  SERVICING  AGREEMENT,  dated as of August 1, 1998,
among CWMBS,  INC., a Delaware  corporation,  as  depositor  (the  "Depositor"),
COUNTRYWIDE  HOME  LOANS,  INC.,  a New York  corporation,  as  seller  (in such
capacity,  the "Seller") and as master  servicer (in such capacity,  the "Master
Servicer"),  and THE BANK OF NEW YORK, a banking corporation organized under the

                                 WITNESSETH THAT

          In  consideration  of the  mutual  agreements  herein  contained,  the
parties hereto agree as follows:

                              PRELIMINARY STATEMENT

          The  Depositor is the owner of the Trust Fund that is hereby  conveyed
to the Trustee in return for the Certificates. The Trust Fund for federal income
tax purposes will consist of two REMICs.  The  Subsidiary  REMIC will consist of
all of the  assets  constituting  the Trust  Fund and will be  evidenced  by the
Subsidiary  REMIC  Regular  Interests  (which  will be  uncertificated  and will
represent the "regular  interests" in the Subsidiary  REMIC) and the SR Interest
as the single "residual interest" in the Subsidiary REMIC. The Trustee will hold
the  Subsidiary  REMIC Regular  Interests.  The Master REMIC will consist of the
Subsidiary  REMIC  Regular  Interests  and  will  be  evidenced  by the  Regular
Certificates  (which will represent the "regular interests" in the Master REMIC)
and the MR Interest as the single  "residual  interest" in the Master REMIC. The
Class A-R Certificates  will represent  beneficial  ownership of the SR Interest
and the MR Interest.  The "latest possible maturity date" for federal income tax
purposes of all interests  created hereby will be the Latest  Possible  Maturity
Date.

          The following table sets forth  characteristics  of the  Certificates,
together with the minimum denominations and integral multiples in excess thereof
in which such Classes  shall be issuable  (except that one  Certificate  of each
Class of Certificates may be issued in a different amount and, in addition,  one
Residual  Certificate  representing  the Tax Matters Person  Certificate  may be
issued in a different amount):

related  Mortgage Loan and 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  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  assignments of 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  receipt  thereof  and that 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  under  the laws of which in the  opinion  of
counsel 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 hereof.

          Notwithstanding  anything to the  contrary in this  Agreement,  within
thirty days after the Closing  Date,  the Seller shall either (i) deliver to the
Depositor,  or at the Depositor's direction, to the Trustee or other designee of
the Depositor  the Mortgage  File as required  pursuant to this Section 2.01 for
each Delay Delivery  Mortgage Loan or (ii) (A) substitute a Substitute  Mortgage
Loan for the Delay Delivery Mortgage Loan or (B) repurchase the Delayed Delivery
Mortgage Loan,  which  substitution  or repurchase  shall be accomplished in the
manner and subject to the  conditions  set forth in Section 2.03  (treating each
Delay  Delivery  Mortgage  Loan as a Deleted  Mortgage Loan for purposes of such
Section 2.03), provided, however, that if the Seller fails to deliver a Mortgage
               --------  -------
File for any Delay Delivery  Mortgage Loan within the thirty-day period provided
in the prior  sentence,  the  Seller  shall use its best  reasonable  efforts to
effect a substitution,  rather than a repurchase of, such Deleted  Mortgage Loan
and  provided  further  that the cure period  provided for in Section 2.02 or in
Section 2.03 shall not apply to the initial  delivery of the  Mortgage  File for
such Delay  Delivery  Mortgage  Loan,  but rather the Seller shall have five (5)
Business  Days to cure such  failure to deliver.  At the end of such  thirty-day
period,  the Trustee  shall send a Delay  Delivery  Certification  for the Delay
Delivery  Mortgage Loans delivered  during such thirty-day  period in accordance
with the provisions of Section 2.02.

          SECTION   2.02.  Acceptance   by  Trustee  of  the  Mortgage   Loans.
                           ----------------------------------------------------

          The Trustee  acknowledges  receipt of the documents  identified in the
Initial  Certification in the form annexed hereto as Exhibit F 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 F. 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.

          On or about the  thirtieth  (30th)  day after the  Closing  Date,  the
Trustee shall  deliver to the  Depositor,  the Master  Servicer and the Seller a
Delay Delivery  Certification  in the form annexed hereto as Exhibit G, with any
applicable exceptions noted thereon.

          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
hereof, 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 above 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 Master Servicer.
                         -------------------

          (a)  Countrywide  Home Loans,  Inc.,  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;  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  hereof,  if
any, and any such substitution pursuant to (i) 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 and the Mortgage File for any such Substitute  Mortgage
Loan.  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 the
representations  and warranties  described in this Section which are made to the
best of the Seller's knowledge, if it is discovered by either the Depositor, the
Seller or the Trustee that the substance of such  representation and warranty is
inaccurate and such inaccuracy materially and adversely affects the value of the
related  Mortgage  Loan  or the  interests  of the  Certificateholders  therein,
notwithstanding  the Seller's lack of knowledge with respect to the substance of
such representation or warranty, such inaccuracy shall be deemed a breach of the
applicable  representation or warranty.

          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 with respect to such Deleted  Mortgage  Loans shall be deposited in 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 3.05 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) hereof,  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.  Upon  discovery by the Depositor or the Trustee of a breach of any
of the foregoing  representations  and warranties set forth in this Section 2.04
(referred  to herein as a  "breach"),  which  breach  materially  and  adversely
affects  the  interest of the  Certificateholders,  the party  discovering  such
breach shall give prompt written notice to the others and to each Rating Agency.

          SECTION  2.05.  Delivery  of Opinion of  Counsel  in  Connection  with
                          ------------------------------------------------------
                          Substitutions.
                          -------------

          (a)  Notwithstanding  any  contrary  provision of this  Agreement,  no
substitution pursuant to Section 2.02 or Section 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  Trust  Fund 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 each REMIC  hereunder
shall  be the  Trustee  and  the  Trustee  shall  hold  the Tax  Matters  Person
Certificate. Each REMIC's fiscal year shall be the calendar year.

          SECTION 2.08.  Covenants of the Master Servicer.
                         -------------------------------- 

          The Master Servicer hereby  covenants to the Depositor and the Trustee
          as follows:

          (a)  the  Master  Servicer  shall  comply  in the  performance  of its
          obligations  under  this  Agreement  with  all  reasonable  rules  and
          requirements of the insurer under each Required Insurance Policy; and

          (b) no  written  information,  certificate  of an  officer,  statement
          furnished in writing or written report delivered to the Depositor, any
          affiliate  of the  Depositor or the Trustee and prepared by the Master
          Servicer  pursuant to this Agreement will contain any untrue statement
          of a material fact or omit to state a material fact  necessary to make
          such information, certificate, statement or report not misleading.

                                  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 customary and usual standards of practice of prudent mortgage loan
servicers.  In connection  with such  servicing and  administration,  the Master
Servicer  shall have full  power and  authority,  acting  alone  and/or  through
Subservicers  as provided in Section 3.02 hereof,  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;  provided that the Master Servicer shall not take any action that
is  inconsistent  with or  prejudices  the  interests  of the Trust  Fund or the
Certificateholders  in any  Mortgage  Loan or the  rights and  interests  of the
Depositor,  the Trustee and the  Certificateholders  under this  Agreement.  The
Master  Servicer shall  represent and protect the interests of the Trust Fund in
the same manner as it protects its own  interests  in mortgage  loans in its own
portfolio in any claim,  proceeding or litigation regarding a Mortgage Loan, and
shall not make or permit any  modification,  waiver or amendment of any Mortgage
Loan which would cause the Trust Fund 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 the Depositor and the Trustee,  is hereby  authorized
and  empowered  by the  Depositor  and the  Trustee,  when the  Master  Servicer
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 the  standards of the  preceding  paragraph,  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 3.06, and further as
provided in Section 3.08. 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 Subservicer pursuant to a subservicing  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.
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  Subservicer  on behalf of the Master
Servicer.  Notwithstanding the provisions of any subservicing agreement,  any of
the provisions of this Agreement relating to agreements or arrangements  between
the Master  Servicer and a  Subservicer  or reference to actions taken through a
Subservicer or otherwise,  the Master Servicer shall remain obligated and liable
to the Depositor,  the Trustee and the  Certificateholders for the servicing and
administration  of the Mortgage Loans in accordance  with the provisions of this
Agreement  without  diminution of such obligation or liability by virtue of such
subservicing agreements or arrangements or by virtue of indemnification from the
Subservicer 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.
All actions of each Subservicer  performed pursuant to the related  subservicing
agreement  shall be performed as an agent of the Master  Servicer  with the same
force and effect as if performed directly by the Master Servicer.

          (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 Subservicer regardless of whether such
payments are remitted by the Subservicer to the Master Servicer.

          SECTION 3.03.  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 3.04.  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 3.09 hereof 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  of Mortgage Loans  pursuant to Section 2.02 or 2.03 hereof,  (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 hereof. 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  subservicing
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  subservicing  agreement  or  substitute  subservicing
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  subservicing
agreement to the assuming party.

          SECTION  3.05.  Collection  of  Mortgage  Loan  Payments;  Certificate
                          ------------------------------------------------------
                          Account; Distribution Account.
                          -----------------------------

          (a) 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 180 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) 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
Subservicers  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;

          (ii) all payments on account of interest on the Mortgage Loans, net of
     the related Master Servicing Fee;

          (iii) all  Insurance  Proceeds and  Liquidation  Proceeds,  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  3.05(e) in  connection  with any losses on  Permitted
     Investments;

          (v) any  amounts  required  to be  deposited  by the  Master  Servicer
     pursuant to Section 3.09(b),  3.09(d), and in respect of net monthly rental
     income  from  REO  Property  pursuant  to  Section  3.11  hereof;

          (vi) 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 related 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.  All funds deposited in the  Certificate  Account
shall be held in trust for the Certificateholders  until withdrawn in accordance
with Section 3.08.

          (c) [Reserved]

          (d) 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 3.08(a)(ix);

          (ii) any amount  deposited by the Master Servicer  pursuant to Section
     3.05(d) 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 3.08. In
no event shall the Trustee incur liability for withdrawals from the Distribution
Account at the direction of the Master Servicer.

          (e)  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 fund or  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 3.05.

          (f) 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  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 prior to any
change  thereof.

          SECTION 3.06.  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  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 Master  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
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 out of related collections for any payments made pursuant to
Sections  3.01  hereof  (with  respect to taxes and  assessments  and  insurance
premiums) and 3.09 hereof (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 hereof.  The
Escrow  Accounts shall not be a part of the Trust Fund.

          (c) The Master  Servicer  shall  advance any  payments  referred to in
Section  3.06(a) that are not timely paid by the Mortgagors 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  3.07.   Access  to  Certain   Documentation  and  Information
                           -----------------------------------------------------
                           Regarding the Mortgage Loans.
                           ----------------------------

          The  Master  Servicer  shall  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 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  shall be  entitled  to be  reimbursed  by each  such
Certificateholder  for  actual  expenses  incurred  by the  Master  Servicer  in
providing such reports and access.

          SECTION 3.08.  Permitted  Withdrawals from the Certificate Account and
                         -------------------------------------------------------
                         Distribution Account.
                         --------------------

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

          (i) to pay to the  Master  Servicer  (to  the  extent  not  previously
     retained by the Master Servicer) the servicing  compensation to which it is
     entitled  pursuant to Section 3.14, and to pay to the Master  Servicer,  as
     additional  servicing  compensation,  earnings on or investment income with
     respect to funds in or credited to the Certificate Account;

          (ii) to reimburse the Master Servicer for  unreimbursed  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 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  3.06 and (b) for  unpaid  Master  Servicing  Fees as  provided  in
     Section 3.11  hereof;

          (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 or 3.11, 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  hereof;

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

          (ix) on or prior to the Distribution Account Deposit Date, to withdraw
     an amount equal to the related Available Funds and the Trustee Fee for such
     Distribution  Date 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 hereof.

          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  Loans(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 hereof.

          SECTION 3.09. 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.  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. Any cost incurred by the Master 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  3.08  hereof.  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.

          (b) 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,  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,  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.

          (c) The Master  Servicer  shall not 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,  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.

          Except  with  respect  to any Lender PMI  Mortgage  Loans,  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. With respect to the Lender PMI Mortgage  Loans,  the Master  Servicer shall
maintain the Primary Insurance Policy for the life of such Mortgage Loans.

          The  Master  Servicer  agrees  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.

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

          SECTION  3.10.   Enforcement   of  Due-on-Sale   Clauses;   Assumption
                           -----------------------------------------------------
                           Agreements.
                           ----------

          (a) Except as otherwise  provided in this  Section,  when any property
subject to a Mortgage has been conveyed by the  Mortgagor,  the Master  Servicer
shall to the  extent  that it has  knowledge  of such  conveyance,  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,  the Master
Servicer is not 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 the
Master Servicer is prohibited by law from enforcing any such due-on-sale clause,
or if coverage under any Required Insurance Policy would be adversely  affected,
or if nonenforcement is otherwise  permitted  hereunder,  the Master Servicer is
authorized,  subject to Section 3.10(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
3.10(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  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 3.10(a) hereof, 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 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 for entering into an assumption or substitution
of liability  agreement  will be retained by the Master  Servicer as  additional
servicing compensation.

          SECTION 3.11. Realization Upon Defaulted Mortgage Loans; Repurchase of
                        --------------------------------------------------------
                        Certain Mortgage Loans.
                        ----------------------

          The Master Servicer shall use reasonable  efforts to foreclose upon or
otherwise  comparably  convert the ownership of properties  securing such of the
Mortgage  Loans  as 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 such practices and procedures as it shall deem necessary or advisable and
as shall be normal and usual in its general  mortgage  servicing  activities and
meet the  requirements  of the  insurer  under any  Required  Insurance  Policy;
provided,  however, that 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 thereunder. 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 the
same manner and to such extent as is customary  in the  locality  where such REO
Property is located 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 any tax
reporting 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 two 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 two-year
period will not result in the imposition of taxes on  "prohibited  transactions"
of any REMIC hereunder as defined in section 860F of the Code or cause any REMIC
hereunder  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  any  REMIC  hereunder  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.

          In the  event of a  default  on a  Mortgage  Loan one or more of whose
obligor  is not a United  States  Person,  as that term is  defined  in  Section
7701(a)(30) of the Code, in connection  with any foreclosure or acquisition of a
deed  in  lieu of  foreclosure  (together,  "foreclosure")  in  respect  of such
Mortgage Loan, the Master Servicer will cause  compliance with the provisions of
Treasury Regulation Section  1.1445-2(d)(3) (or any successor thereto) necessary
to assure that no withholding tax obligation arises with respect to the proceeds
of such  foreclosure  except  to the  extent,  if  any,  that  proceeds  of such
foreclosure are required to be remitted to the obligors on such Mortgage Loan.

          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,  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  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 for any related  unreimbursed  Servicing
Advances and Master Servicing Fees; second, to reimburse the Master Servicer for
any unreimbursed  Advances;  third, to reimburse the Certificate Account for any
Nonrecoverable  Advances (or portions thereof) that were previously withdrawn by
the Master  Servicer  pursuant  to  Section  3.08(a)(iii)  that  related to such
Mortgage Loan;  fourth, to accrued and unpaid interest (to the extent no Advance
has been made for such amount or any such  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 fifth, 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 3.14.

          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.

          SECTION 3.12.  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.  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  3.13.  Documents  Records and Funds in  Possession  of Master
                          ------------------------------------------------------
                          Servicer to be Held for the Trustee.
                          -----------------------------------

          Notwithstanding  any other  provisions of this  Agreement,  the Master
Servicer  shall  transmit  to the  Trustee as  required  by this  Agreement  all
documents  and  instruments  in  respect  of a  Mortgage  Loan  coming  into the
possession  of the Master  Servicer from time to time and 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 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 3.14.  Servicing Compensation.
                         ----------------------

          As  compensation  for its activities  hereunder,  the Master  Servicer
shall be entitled to retain or withdraw from the  Certificate  Account an amount
equal to the Master  Servicing  Fee for each  Mortgage  Loan,  provided that the
aggregate Master  Servicing Fee with respect to any  Distribution  Date shall be
reduced  (i) by an amount  equal to the  aggregate  of the  Prepayment  Interest
Shortfalls,  if any, with respect to such  Distribution  Date,  but not below an
amount  equal  to  one-half  of the  aggregate  Master  Servicing  Fee for  such
Distribution  Date  before  reduction  thereof  in  respect  of such  Prepayment
Interest  Shortfalls,  and (ii) with respect to the first  Distribution Date, an
amount equal to any amount to be deposited into the Distribution  Account by the
Depositor pursuant to Section 2.01(a) and not so deposited.

          Additional  servicing  compensation  in the form of  Excess  Proceeds,
Prepayment Interest Excess, 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 3.05 hereof. The
Master  Servicer  shall  be  required  to pay  all  expenses  incurred  by it in
connection with its master 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.

          SECTION 3.15.  Access to Certain Documentation.
                         -------------------------------

          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 without charge,  but only upon reasonable and prior written request and
during normal business hours at the offices  designated by the Master  Servicer.
Nothing in this Section  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 to provide access as provided
in this Section as a result of such obligation  shall not constitute a breach of
this Section.

          SECTION 3.16.  Annual Statement as to Compliance.
                         ---------------------------------

          The Master  Servicer shall deliver to the Depositor and the Trustee on
or  before  120  days  after  the  end of the  Master  Servicer's  fiscal  year,
commencing with its 1999 fiscal year, an Officer's  Certificate  stating,  as to
the signer  thereof,  that (i) a review of the activities of the Master Servicer
during the preceding calendar year and of the performance of the Master Servicer
under this Agreement has been made under such officer's  supervision and (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.  The Trustee shall forward a copy of each such statement to each Rating
Agency.

          SECTION  3.17.  Annual  Independent  Public   Accountants'   Servicing
                          ------------------------------------------------------
                          Statement; Financial Statements.
                          -------------------------------

          On or before 120 days after the end of the  Master  Servicer's  fiscal
year,  commencing  with its 1999 fiscal year, the Master Servicer at its expense
shall cause a nationally or regionally  recognized  firm of  independent  public
accountants  (who may also render  other  services to the Master  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 such statement is delivered by the
Master Servicer to the Trustee.

          SECTION 3.18.  Errors and Omissions Insurance; Fidelity Bonds.
                         ----------------------------------------------

          The Master  Servicer  shall for so long as it acts as master  servicer
under this  Agreement,  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  and (b) a fidelity bond in respect of its officers,
employees  and agents.  Each such policy or policies  and bond shall,  together,
comply  with the  requirements  from time to time of FNMA or FHLMC  for  persons
performing servicing for mortgage loans purchased by FNMA or FHLMC. In the event
that any such policy or bond ceases to be in effect,  the Master  Servicer shall
obtain a  comparable  replacement  policy or bond  from an  insurer  or  issuer,
meeting the requirements set forth above as of the date of such replacement.

                                   ARTICLE IV

                                DISTRIBUTIONS AND
                         ADVANCES BY THE MASTER SERVICER

          SECTION 4.01.  Advances.
                         --------

          The Master  Servicer shall determine on or before each Master Servicer
Advance  Date  whether  it is  required  to  make  an  Advance  pursuant  to the
definition  thereof. If the Master Servicer determines it is required to make an
Advance,  it shall,  on or before the Master Servicer  Advance Date,  either (i)
deposit into the Certificate Account an amount equal to the Advance or (ii) make
an appropriate entry in its records relating to the Certificate Account that any
Amount  Held for Future  Distribution  has been used by the Master  Servicer  in
discharge of its obligation to make any such Advance. Any funds so applied shall
be replaced  by the Master  Servicer  by deposit in the  Certificate  Account no

is the PO Formula  Principal  Amount and the  denominator of which is the sum of
the PO Formula Principal Amount and the Senior Principal Distribution Amount and
(B) the amount distributable on the Senior Certificates, other than the Class PO
Certificates,  in respect of principal  shall be equal to the product of (1) the
Amount Available for Senior Principal and (2) a fraction, the numerator of which
is the Senior Principal  Distribution Amount and the denominator of which is the
sum of the Senior  Principal  Distribution  Amount and the PO Formula  Principal
Amount.

          (b)  On  each  Distribution  Date  prior  to  the  Class  A-7  Accrual
Termination  Date, the Class A-7 Accrual Amount for such Distribution Date shall
not  (except as provided in the second to last  sentence in this  paragraph)  be
distributed  as interest  with respect to the Class A-7  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 prior to the Class A-7
Accrual   Termination  Date  on  which  principal  payments  on  the  Class  A-7
Certificates are distributed pursuant to the 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 related
Accretion  Directed  Certificates  pursuant  to  Section  4.02(a)(iii)  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-7 Certificates  immediately  prior to
such Distribution Date. On any Distribution Date that the Accrual Amount for the
Class A-7  Certificates is in excess of the amount necessary to reduce the Class
Certificate  Balance of the Class A-4, Class A-5 and Class A-6  Certificates  to
their respective  Targeted Balances,  the amount of such excess shall be paid to
the Class A-7 Certificates as principal.  Notwithstanding any such distribution,
the Class A-7 Certificates shall continue to be a Class of Accrual  Certificates
on each  subsequent  Distribution  Date until the Class A-7 Accrual  Termination
Date.

          On each Distribution Date prior to the Class A-13 Accrual  Termination
Date, the Class A-13 Accrual Amount for such Distribution Date shall not (except
as provided in the second to last sentence in this  paragraph) be distributed as
interest with respect to the Class A-13  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  prior  to  the  Class  A-13  Accrual
Termination Date on which principal  payments on the Class A-13 Certificates are
distributed  pursuant to the 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  related  Accretion
Directed  Certificates  pursuant to Section  4.02(a)(iii) 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-13  Certificates  immediately  prior to such Distribution
Date.  On any  Distribution  Date that the  Accrual  Amount  for the Class  A-13
Certificates  is  in  excess  of  the  amount  necessary  to  reduce  the  Class
Certificate  Balance  of the Class  A-11 and Class  A-12  Certificates  to their
respective  Targeted  Balances,  the amount of such excess  shall be paid to the
Class A-13 Certificates as principal. Notwithstanding any such distribution, the
Class A-13 Certificates shall continue to be a Class of Accrual  Certificates on
each subsequent Distribution Date until the Class A-13 Accrual Termination Date.

          On each Distribution Date prior to the Class A-14 Accrual  Termination
Date, the Class A-14 Accrual Amount for such Distribution Date shall not (except
as provided in the second to last sentence in this  paragraph) be distributed as
interest with respect to the Class A-14  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  prior  to  the  Class  A-14  Accrual
Termination Date on which principal  payments on the Class A-14 Certificates are
distributed  pursuant to the 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  related  Accretion
Directed  Certificates  pursuant to Section  4.02(a)(iii) 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-14  Certificates  immediately  prior to such Distribution
Date.  On any  Distribution  Date that the  Accrual  Amount  for the Class  A-14
Certificates  is  in  excess  of  the  amount  necessary  to  reduce  the  Class
Certificate Balance of the Class A-11, Class A-12 and Class A-13 Certificates to
their respective  Targeted Balances,  the amount of such excess shall be paid to
the Class A-14 Certificates as principal. Notwithstanding any such distribution,
the Class A-14 Certificates shall continue to be a Class of Accrual Certificates
on each subsequent  Distribution  Date until the Class A-14 Accrual  Termination
Date.

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

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

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

          (f) On each Distribution Date, Available Funds shall be distributed on
the Subsidiary REMIC Regular Interests,  in each case in an amount sufficient to
make the  distributions  to the  Corresponding  Classes of  Certificates on such
Distribution Date in accordance with the provisions of Section 4.02(a).

                         --------

          SECTION 4.04. 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. For purposes of allocating losses to
the Subordinated Certificates, the Class M Certificates will be deemed to have a
lower  numerical  class  designation,  and to be of a  higher  relative  payment
priority, than each other Class of Subordinated Certificates.

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

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

               (ii) (1) the  applicable  Non-PO  Percentage of any Realized Loss
     (other than an Excess  Loss) shall be allocated  first to the  Subordinated
     Certificates  in  reverse  order  of  their   respective   numerical  Class
     designations  (beginning with the Class of Subordinated  Certificates  then
     outstanding  with  the  highest  numerical  Class  designation)  until  the
     respective Class Certificate Balance of each such Class is reduced to zero,
     and second to the  Senior  Certificates  (other  than the  Notional  Amount
     Certificates and the Class PO Certificates), pro rata on the basis of their
     respective  Class  Certificate  Balances  or, in the case of each  Class of
     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 been reduced to zero; and

     (2)  the  applicable  Non-PO  Percentage  of any  Excess  Losses  shall  be
     allocated  to the  Senior  Certificates  (other  than the  Notional  Amount
     Certificates   and  the  Class  PO   Certificates)   and  the  Subordinated
     Certificates then  outstanding,  pro rata, on the basis of their respective
     Class  Certificate  Balances  or,  in the  case of each  Class  of  Accrual
     Certificates,  on the  basis  of  the  lesser  of  their  respective  Class
     Certificate   Balances  and  their  respective  initial  Class  Certificate
     Balances, in each case immediately prior to the related Distribution Date.

          (b)  The  Class  Certificate  Balance  of the  Class  of  Subordinated
Certificates then outstanding with the highest numerical Class designation shall
be  reduced  on each  Distribution  Date by the  sum of (i)  the  amount  of any
payments on the Class PO  Certificates  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 (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 Pool Stated Principal
Balance for the following Distribution Date.

          (c) Any  Realized  Loss  allocated to a Class of  Certificates  or any
reduction in the Class Certificate  Balance of a Class of Certificates  pursuant
to Section 4.04(a) above shall be allocated among the Certificates of such Class
in proportion to their respective  Certificate  Balances.  (d) Any allocation of
Realized  Losses to a  Certificate  or to any  Component or any reduction in the
Certificate Balance of a Certificate, pursuant to Section 4.04(a) above shall be
accomplished by reducing the Certificate  Balance or Component  Balance thereof,
as  applicable,  immediately  following  the  distributions  made on the related
Distribution Date in accordance with the definition of "Certificate  Balance" or
"Component Balance," as the case may be.

          SECTION 4.06. Monthly Statements to Certificateholders.
                        ----------------------------------------

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

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

               (iv) the Class Certificate  Balance of each Class of Certificates

     of the calendar month preceding such Distribution Date;

               (xi)  with  respect  to any  Mortgage  Loan  that  became  an REO
     Property during the preceding  calendar  month,  the loan number and Stated
     Principal  Balance of such Mortgage Loan as of the close of business on the
     Determination  Date  preceding  such  Distribution  Date  and  the  date of

               (xii)  the  total  number  and  principal   balance  of  any  REO
     Properties  (and market value, if available) as of the close of business on
     the Determination Date preceding such Distribution Date;

               (xiii)  the  Senior  Prepayment   Percentage  for  the  following
     Distribution Date;

               (xiv) the aggregate amount of Realized Losses incurred during the

accuracy of the information  provided by the Master  Servicer.  The Trustee will
send a copy of each  statement  provided  pursuant to this  Section 4.06 to each
Rating Agency.

          (c) On or before  the fifth  Business  Day  following  the end of each
Prepayment  Period (but in no event later than the third  Business  Day prior to
the related Distribution Date), the Master Servicer shall deliver to the Trustee
(which   delivery  may  be  by  electronic   data   transmission)  a  report  in
substantially the form set forth as Schedule V hereto.

          (d) 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

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 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.
                           ------------

          (A)  On  each  Interest  Determination  Date  so  long  as  the  LIBOR
Certificates  are outstanding,  the Trustee  determine LIBOR on the basis of the
British Bankers'  Association  ("BBA") "Interest  Settlement Rate" for one-month
deposits in U.S.  dollars as found on Telerate page 3750 as of 11:00 a.m. London
time on each LIBOR  Determination  Date. Interest Settlement Rates currently are
based on rates quoted by sixteen BBA designated  banks as being,  in the view of
such banks,  the offered rate at which  deposits are being quoted to prime banks
in the London interbank market. Such Interest Settlement Rates are calculated by
eliminating  the four highest  rates and the four lowest  rates,  averaging  the
eight remaining  rates,  carrying the result  (expressed as a percentage) out to
six decimal places,  and rounding to five decimal  places.  "Telerate Page 3750"
means  the  display  page  currently  so  designated  on the Dow  Jones  Markets
(formerly Telerate Service) (or such other page as may replace that page on that
service for the purpose of displaying comparable rates or prices.)

          If on the initial LIBOR  Determination  Date,  the Trustee is required
but unable to determine  LIBOR in the manner  provided in the  described  above,
LIBOR for the next Interest Accrual Period will be 5.65%.

          (B) If LIBOR cannot be determined as provided in paragraph (A) of this
Section 4.08, 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.
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, 5.65%.

          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.

          (C) 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,  any Interest  Settlement  Rate, 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 Dow Jones  Markets)  from the BBA
designated  banks,  the Reference  Banks or the New York City banks as to LIBOR,
the Interest  Settlement Rate 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 BBA designated  banks,  the Reference Banks or the New York City banks
or to determine such arithmetic mean, all as provided for in this Section 4.0.8.

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

                                THE CERTIFICATES

          SECTION 5.01. The Certificates.
                        ----------------

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

          Subject to Section 9.02 hereof  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  when  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 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 hereof,  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 forms
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,   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 or arrangement 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,  (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, in
the event the representation letter referred to in the preceding sentence is not
so  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 any 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 save 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.

                        --------

accordance  herewith  only to the  extent of the  obligations  specifically  and
respectively imposed upon and undertaken by them herein.

                        --------

          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

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

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 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,  without  regard  to the  guaranty  provided  by the
Policies,  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.

          made under the terms of this  Agreement,  which failure shall continue

          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, which failure
          materially  affects  the rights of  Certificateholders,  that  failure
          continues  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; provided,
                                                                       --------
          however, that the sixty-day cure period shall not apply to the initial
          -------
          delivery of the Mortgage File for Delay  Delivery  Mortgage  Loans nor
          the failure to substitute or repurchase in lieu thereof; 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,

          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 (vi) of this
Section  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  thereupon  make any Advance
which the Master  Servicer  failed to make subject to Section  3.04 hereof.  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  3.08(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 hereof, the Trustee shall,  subject to and
to the extent  provided in Section 3.04, 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 hereof,  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 hereof 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,  and which is  willing  to service  the  Mortgage  Loans and
executes and delivers to the  Depositor  and the Trustee an agreement  accepting
such delegation and  assignment,  which contains 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 hereof  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; and
provided  further 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,  without  regard to the  guaranty  provided by the
Policies, 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 3.04 hereof, 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.

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.

               (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;

          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

          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

          unless  such  Certificateholders  shall have  offered  to the  Trustee
          reasonable  security or indemnity  satisfactory to the Trustee against

                        ---------------------------

          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) in
connection with 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 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  super-vision  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).  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 hereof.
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  Master
- --------   -------
Servicer other than the Trustee in its role as successor to the Master Servicer.

          SECTION 8.07. Resignation and Removal of 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 and 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  hereof  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 instrument shall be delivered to the Trustee, one
copy of which  shall be  delivered  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 instruments
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 hereof.

          SECTION 8.08. Successor Trustee.
                        -----------------

          Any  successor  trustee  appointed  as provided in Section 8.07 hereof
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 hereof 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 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 hereof  without the  execution or filing of any
paper or further act on the part of any of the parties  hereto,  anything herein
to the contrary notwithstanding.

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

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

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

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

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

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

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

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

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

          SECTION 8.11. Tax Matters.
                        -----------

          It is  intended  that the  assets  with  respect  to which  any  REMIC
election  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 any such 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 any 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 elections 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 any such 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 any such 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 any such 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 any such REMIC,  enter into
settlement agreements with any governmental taxing agency, extend any statute of
limitations  relating to any tax item of any such REMIC,  and  otherwise  act on
behalf of any such 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,  in the case of any such minimum tax,
or 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,  (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 3.08(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.

                                   ARTICLE IX

                                   TERMINATION

          SECTION 9.01. Termination upon Liquidation or Purchase of all Mortgage
                        --------------------------------------------------------
                        Loans.
                        -----

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

          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 no later than the 10th day of the month next preceding the month of such
final distribution. Any such notice shall specify (a) the Distribution Date upon
which final  distribution on the Certificates will be made upon presentation and
surrender of  Certificates at the office therein  designated,  (b) the amount of
such final distribution,  (c) the location of the office or agency at which such
presentation  and surrender must be made, and (d) that the Record Date otherwise
applicable to such Distribution Date is not applicable, distributions being made
only upon  presentation  and surrender of the Certificates at the office therein
specified.  The Master  Servicer  will give such notice to each Rating Agency at
the time such notice is given to Certificateholders.

          Upon presentation and surrender of the Certificates, the Trustee shall
cause to be distributed to the  Certificateholders  of each Class,  in the order
set forth in Section 4.02 hereof, on the final  Distribution Date, 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 Class PO Certificates,
and (ii) as to the Residual  Certificates,  the amount, if any, which remains on
deposit in the  Distribution  Account  (other than the amounts  retained to meet
claims) after application pursuant to clause (i) above.

          In the event that any affected  Certificateholders shall not surrender
Certificates for cancellation  within six months after the date specified in the
above mentioned  written notice,  the Trustee shall give a second written notice
to  the  remaining   Certificateholders  to  surrender  their  Certificates  for
cancellation and receive the final distribution with respect thereto.  If within
six months after the second  notice all the  applicable  Certificates  shall not
have been surrendered for cancellation,  the Trustee may take appropriate steps,
or may appoint an agent to take  appropriate  steps,  to contact  the  remaining
Certificateholders  concerning  surrender  of their  Certificates,  and the cost
thereof  shall be paid out of the funds and other  assets which remain a part of
the Trust  Fund.  If within one year after the  second  notice all  Certificates
shall   not  have   been   surrendered   for   cancellation,   the   Class   A-R
Certificateholders  shall be entitled to all unclaimed funds and other assets of
the Trust Fund which remain subject hereto.

          SECTION 9.03. Additional Termination Requirements.
                        -----------------------------------

          (a) In the event the Master Servicer  exercises its purchase option as
provided in Section 9.01, the Trust Fund shall be terminated in accordance  with
the following additional requirements, unless the Trustee has been supplied with
an Opinion of Counsel, at the expense of the Master Servicer, to the effect that
the failure to comply with the  requirements  of this  Section 9.03 will not (i)
result in the imposition of taxes on "prohibited  transactions"  on any REMIC as
defined in section 860F of the Code,  or (ii) cause any 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  or  the  Tax  Matters  Person),  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 any REMIC hereby agrees to adopt and sign
such a plan of  complete  liquidation  upon the  written  request  of the Master
Servicer,  and the  receipt of the  Opinion of  Counsel  referred  to in Section
9.03(a)(1)  and to take such  other  action in  connection  therewith  as may be
reasonably requested by the Master Servicer.

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

                            MISCELLANEOUS PROVISIONS

          SECTION 10.01. Amendment.
                         ---------

          This Agreement may be amended from time to time by the Depositor,  the
Master   Servicer   and  the   Trustee   without  the  consent  of  any  of  the
Certificateholders  (i) to cure any  ambiguity  or mistake,  (ii) to correct any
defective  provision  herein or to supplement any provision  herein which may be
inconsistent with any other provision herein,  (iii) to add to the duties of the
Depositor,  the Seller or the Master Servicer,  (iv) to add any other provisions
with respect to matters or questions arising hereunder or (v) to modify,  alter,
amend,  add to or  rescind  any of the  terms or  provisions  contained  in this
Agreement;  provided that any action pursuant to clauses (iv) or (v) above shall
not, as evidenced by an Opinion of Counsel  (which  Opinion of Counsel shall not
be an  expense  of the  Trustee  or the  Trust  Fund),  adversely  affect in any
material respect the interests of any Certificateholder; provided, however, that
                                                         --------  -------
the amendment  shall not be deemed to adversely  affect in any material  respect
the interests of the  Certificateholders  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 any REMIC as a REMIC under the Code, (ii) avoid or minimize the
risk of the  imposition of any tax on any 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 any REMIC or the  Certificateholders or cause any 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 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

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 of
the Trust Fund by the  Depositor  to the  Trustee  be, and be  construed  as, an
absolute sale thereof to the Trustee.  It is, further,  not the intention of the
parties that such  conveyance be deemed a pledge thereof by the Depositor to the
Trustee. However, in the event that,  notwithstanding the intent of the parties,
such assets are held to be the  property of the  Depositor,  or if for any other
reason this  Agreement  is held or deemed to create a security  interest in 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  conveyance  provided  for in this  Agreement  shall be deemed to be an
assignment  and a grant by the Depositor to the Trustee,  for the benefit of the
Certificateholders,  of a security interest in all of the assets that constitute
the Trust Fund, whether now owned or hereafter acquired.

          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
Certificateholder.

          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

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

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

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

          5. The final payment to Certificateholders.

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

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 writing
and shall be deemed to have been duly given when delivered to (a) in the case of
the Depositor,  CWMBS,  Inc., 4500 Park Granada,  Calabasas,  California  91302,
Attention: David A. Spector, (b) in the case of the Master Servicer, Countrywide
Home Loans,  Inc., 4500 Park Granada,  Calabasas,  California 91302,  Attention:
Kevin W.  Bartlett or such other  address as may be  hereafter  furnished to the

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.
                         ----------

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.
