          THIS POOLING AND SERVICING  AGREEMENT,  dated as of May 1, 1998, among
CWMBS, INC., a Delaware  corporation,  as depositor (the "Depositor"),  INDYMAC,
INC.  ("IndyMac"),  a Delaware  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 laws of the
State of New York, as trustee (the "Trustee").

                                 WITNESSETH THAT

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

                              PRELIMINARY STATEMENT

          The  Depositor  owns the Mortgage  Loans and other  property  conveyed
hereby to the Trustee in return for the  Certificates.  The Trustee  shall elect
for federal  income tax  purposes to treat the Trust Fund as two  separate  real
estate mortgage investment conduits (each a "REMIC", or, in the alternative, the
"Subsidiary  REMIC" and the "Master REMIC").  The Subsidiary REMIC will hold the
Mortgage  Loans and other  property  conveyed  to  Trustee  and will  issue four
classes  of  uncertificated   Subsidiary  Regular  Interests,   which  shall  be
designated as "regular interests",  and the SR Interest, which shall be the sole
"residual  interest" in the  Subsidiary  REMIC.  The  Subsidiary  REMIC  Regular
Interests  will be held as assets by the Master  REMIC.  The  Master  REMIC will
issue the Regular  Certificates,  which shall represent  beneficial ownership of
the regular  interests in the Master REMIC, and the MR Interest,  which shall be
the sole residual interest in the Master REMIC. The Class A-R Certificates shall
evidence  beneficial  ownership of the Class SR and the Class MR Interests.  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):

          There shall be the following four classes of Subsidiary  REMIC Regular
Interests, each of which is hereby designated as a REMIC regular interest in the
Subsidiary REMIC for purposes of Section 860G(a)(1) of the Code.

          Subsidiary  REMIC Regular  Interest 1 shall have an initial  principal
balance as of the Cut-off Date equal to $225,719,980  and shall bear interest at
a Pass-Through  Rate equal to the weighted  average of the Adjusted Net Mortgage
Rates of the Non-Discount  Mortgage Loans in Loan Group 1. The principal balance
of the Subsidiary REMIC Regular Interest 1 shall be reduced on each Distribution
Date for  principal  payments and Realized  Losses so that for any  Distribution
Date the principal  balance of the  Subsidiary  REMIC  Regular  Interest 1 shall
correspond  to the  Notional  Amount  of the  Class  X-1a  Certificate  for such
Distribution Date.

          Subsidiary  REMIC Regular  Interest 2 shall have an initial  principal
balance as of the Cut-off Date equal to $63,087,795 and shall bear interest at a
Pass-Through  Rate equal to the  weighted  average of the  Adjusted Net Mortgage
Rates of the Non-Discount  Mortgage Loans in Loan Group 1. The principal balance
of the Subsidiary REMIC Regular Interest 2 shall be reduced on each Distribution
Date for  principal  payments and Realized  Losses so that for any  Distribution
Date the principal  balance of the  Subsidiary  REMIC  Regular  Interest 2 shall
correspond  to the  Notional  Amount  of the  Class  X-1b  Certificate  for such
Distribution Date.

          Subsidiary  REMIC Regular  Interest 3 shall have an initial  principal
balance as of the Cut-off Date equal to the Senior  Percentage  for Loan Group 2
and shall bear interest at a Pass-Through  Rate equal to the weighted average of
the  Adjusted  Net  Mortgage  Rates of the  Mortgage  Loans in Loan Group 2. The
principal balance of the Subsidiary REMIC Regular Interest 3 shall be reduced on
each  Distribution  Date for principal  payments and Realized Losses so that for
any  Distribution  Date the principal  balance of the  Subsidiary  REMIC Regular
Interest 3 shall correspond to the Senior Percentage for Loan Group 2.

          Subsidiary  REMIC Regular  Interest 4 shall have an initial  principal
balance as of the Cut-off  Date equal to the  Subordinated  Percentage  for Loan
Group 2 and shall bear  interest at a  Pass-Through  Rate equal to the  weighted
average of the Adjusted Net Mortgage  Rates of the Mortgage  Loans in Loan Group
2. The principal  balance of the  Subsidiary  REMIC Regular  Interest 4 shall be
reduced on each Distribution Date for principal  payments and Realized Losses so
that for any  Distribution  Date the principal  balance of the Subsidiary  REMIC
Regular  Interest 4 shall  correspond to the  Subordinated  Percentage  for Loan
Group 2.

          The Class SR Interest  shall have an initial  principal  balance as of
the Cut-off Date of $100 and shall bear interest at the rate of 6.75%. Principal
payments  required to be made on the Class SR Interest on any Distribution  Date
shall  correspond to the principal  payments to be made on the Class MR Interest
for such Distribution Date.

          For  federal  income tax  purposes,  the Class X-2  Certificate  shall
comprise two components. The first component represents the right to receive, on
any Distribution Date on and before the First Option Date, all interest payments
on the Subsidiary REMIC Regular  Interest 3 in excess of interest  payments at a
per annum rate of 6.75%,  and on any  Distribution  Date after the First  Option
Date, all interest payments on the Subsidiary REMIC Regular Interest 3 in excess
of  interest  payments  at a per  annum  rate of  7.25%.  The  second  component
represents the right to receive, on any Distribution Date, all interest payments
on the Subsidiary REMIC Regular  Interest 4 in excess of interest  payments at a
per annum rate of 6.75%.

          Each  of  the   Regular   Certificates,   other  than  the  Class  X-2
Certificates,  and each  component  of the  Class  X-2  Certificate,  is  hereby
designated  as a REMIC  regular  interest  in the Master  REMIC for  purposes of
Section 860G(a)(1).

                          CONVEYANCE OF MORTGAGE LOANS;
                         REPRESENTATIONS AND WARRANTIES

     Section 2.01. Conveyance of Mortgage Loans.

          (a) The Seller,  concurrently  with the execution and delivery hereof,
hereby  sells,  transfers,  assigns,  sets  over and  otherwise  conveys  to the
Depositor,  without recourse, all the right, title and interest of the Seller in
and to the Mortgage  Loans,  including  all interest and  principal  received or
receivable  by the Seller on or with  respect to the  Mortgage  Loans  after the
Cut-off  Date and all  interest and  principal  payments on the  Mortgage  Loans
received  prior to the Cut-off Date in respect of  installments  of interest and
principal due thereafter,  but not including  payments of principal and interest
due and payable on the Mortgage Loans on or before the Cut-off Date. On or prior
to the  Closing  Date,  the Seller  shall  deliver to the  Depositor  or, at the
Depositor's  direction,  to the Trustee or other designee of the Depositor,  the
Mortgage File for each Mortgage Loan listed in the Mortgage Loan Schedule.  Such
delivery of the Mortgage Files shall be made against payment by the Depositor of
the purchase price,  previously  agreed to by the Seller and Depositor,  for the
Mortgage  Loans.  With respect to any  Mortgage  Loan that does not have a first
payment  date on or before  the Due Date in the month of the first  Distribution
Date,  the  Seller  shall  deposit  into the  Distribution  Account on the first
Distribution Account Deposit Date an amount equal to one month's interest at the
related Adjusted Net Mortgage Rate on the Cut-off Date Principal Balance of such
Mortgage  Loan.  If the Seller  shall fail to deposit  such  amount by the first
Distribution Account Deposit Date, the Trustee shall deposit such amount.

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

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

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

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

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

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

                    (iv)   the   original   or   copies   of  each   assumption,
          modification, written assurance or substitution agreement, if any;

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

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

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

                         (B) The executed Security Agreement;

                         (C) The executed Proprietary Lease;

                         (D) The executed Recognition Agreement;

                         (E) The executed assignment of Recognition Agreement;

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     Section 2.06. Execution and Delivery of Certificates.

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

     Section 2.07. REMIC Matters.

          The  Preliminary  Statement  sets forth the  designations  and "latest
possible maturity date" for federal income tax purposes of all interests created
hereby.  The  "Startup  Day" for purposes of the REMIC  Provisions  shall be the
Closing  Date.  The "tax matters  person"  with respect to 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.

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

     Section 3.01. Master Servicer to Service Mortgage Loans.

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

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

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

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

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

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

     Section 3.03. Successor Servicers.

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

     Section 3.04. Liability of the Master Servicer.

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

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

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

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

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

     Section 3.07. Trustee to Act as Master Servicer.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

          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 3.15. Trustee to Cooperate; Release of Mortgage Files.

          Upon the payment in full of any Mortgage  Loan,  or the receipt by the
Master  Servicer of a  notification  that  payment in full will be escrowed in a
manner customary for such purposes,  the Master Servicer will immediately notify
the Trustee by delivering,  or causing to be delivered,  a "Request for Release"
substantially  in the form of  Exhibit  N. Upon  receipt  of such  request,  the
Trustee shall promptly release the related Mortgage File to the Master Servicer,
and the Trustee shall at the Master Servicer's  direction execute and deliver to
the Master  Servicer  the  request for  reconveyance,  deed of  reconveyance  or
release or satisfaction of mortgage or such instrument releasing the lien of the
Mortgage  in each  case  provided  by the  Master  Servicer,  together  with the
Mortgage Note with written evidence of cancellation  thereon.  Expenses incurred
in connection with any instrument of satisfaction or deed of reconveyance  shall
be  chargeable  to the  related  Mortgagor.  From  time to time  and as shall be

          (b) [Reserved];

          (c) On each  Distribution  Date on or after the Senior Credit  Support
Depletion  Date,  (i)  notwithstanding  the allocation and priority set forth in
Section 4.02(a)(1)(iii)(x),  the portion of Available Funds for Loan Group 1 and

(prior to making  any  distributions  on such  Distribution  Date) and until the
Class Certificate Balances thereof are reduced to zero; and (ii) notwithstanding
the allocation and priority set forth in Section 4.02(a)(2)(iii)(x), the portion
of Available Funds for Loan Group 2 and Remaining Available Funds for Loan Group

          (d) On each Distribution Date, the amount referred to in clause (i) of
the  definition  of  Class  Optimal  Interest   Distribution   Amount  for  such
Distribution  Date for each Class of Certificates  shall be reduced with respect
to each Loan Group by (i) the  related  Class' pro rata share of Net  Prepayment
Interest  Shortfalls  for such Loan Group  based (x) with  respect to a Class of
Senior Certificates,  on the related Class Optimal Interest  Distribution Amount
and (y) with respect to a Class of  Subordinated  Certificates on and prior to a
Senior  Depletion Date for the related  Senior  Certificate  Group,  the Assumed

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

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

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

     Section 4.03. [Reserved]

     Section 4.04. [Reserved]

     Section 4.05. Allocation of Realized Losses.

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

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

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

               (ii) (A) the  applicable  Non-PO  Percentage of any Realized Loss
(other  than an Excess  Loss)  shall be  allocated  first,  to the  Subordinated
Certificates in reverse order of their respective  numerical Class designations,
until the respective Class Certificate  Balance of each such Class is reduced to
zero and second,  if Realized  Loss relates to a Loan Group 1 Mortgage  Loan, to
the Loan Group 1 Senior  Certificates  (other than the Class PO,  Class X-1a and
Class  X-1b  Certificates),  pro rata,  on the basis of their  respective  Class
Certificate  Balances  or,  if such  Realized  Loss  relates  to a Loan  Group 2
Mortgage Loan, to the Loan Group 2 Senior Certificates (other than the Class X-2
Certificates),  pro rata,  on the basis of their  respective  Class  Certificate
Balances,  in each case immediately prior to the related Distribution Date until
the respective Class Certificate  Balance of each such Class is reduced to zero;
provided,  however, that any pro rata allocation to the Class I-A-3 Certificates
pursuant to this  subparagraph  (ii)(A)  shall be  allocated  to the Class I-A-6
Certificates,  until the Class  Certificate  Balance thereof has been reduced to
zero;

                    (B) the applicable Non-PO Percentage of any Excess Losses on
the  Mortgage  Loans  in a Loan  Group  shall be  allocated  to the  Classes  of
Certificates of the related Senior  Certificate  Group (other than the Class PO,
Class  X-1a,  Class  X-1b  and  Class  X-2  Certificates)  and the  Subordinated
Certificates then  outstanding,  pro rata, on the basis of, with respect to such
Senior  Certificates,  their  respective  Class  Certificate  Balances and, with
respect to each  Class of  Subordinated  Certificates,  the  applicable  Assumed
Balance for each such Class  relating  to the Loan Group in which such  Realized
Loss occurs in each case until the respective Class Certificate Balances thereof
have been reduced to zero;  provided,  however, on any Distribution Date after a
Senior Depletion Date for a Senior  Certificate Group, such Non-PO Percentage of
Excess Losses on the Mortgage  Loans in the related Loan Group will be allocated
to the  Subordinated  Certificates  on  the  basis  of  their  respective  Class
Certificate  Balances;  provided,  however,  that any pro rata allocation to the
Class  I-A-3  Certificates  pursuant  to  this  subparagraph  (ii)(B)  shall  be
allocated to the Class I-A-6  Certificates,  until the Class Certificate Balance
thereof has been reduced to zero.

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

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

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

     Section 4.06. Monthly Statements to Certificateholders.

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

          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

          principal and interest;

          (b) The Trustee's  responsibility for disbursing the above information

send a copy of each  statement  provided  pursuant to this  Section 4.06 to each
Rating Agency.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                                THE CERTIFICATES

     Section 5.01. The Certificates.

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

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

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

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

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

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

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

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

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

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

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

          Notwithstanding  the  previous  paragraph,  no transfer of the Class Y
Certificate   shall  be  made   unless  the  Trustee   shall  have   received  a
representation  from the transferee of such Certificate,  in the form of Exhibit
O, to the  effect  that such  transferee  (i) is not an  employee  benefit  plan
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  or
using the assets of any such plan or  arrangement  to effect such  transfer,  or
(ii)(A) is using assets of an "investment fund" (within the meaning of Part V(b)
of PTCE 84-14) managed by a "qualified  professional  asset manager" (within the
meaning of Part V(a) of PTCE 84-14)  which has made or properly  authorized  the
decision for such fund to acquire such Certificate under circumstances such that
the purchase  and holding of the  Certificate  is covered by PTCE 84-14,  (B) is
using  assets of a Plan  managed by an  "in-house  asset  manager"  (within  the
meaning of Part IV(a) of PTCE 96-23) which has made or properly  authorized  the
decision for such Plan to acquire such Certificate under circumstances such that
the purchase and holding of the Certificate are covered by PTCE 96-23, (C) is an
insurance company pooled separate account acquiring such Certificate pursuant to
Part I of  PTCE  90-1,  or a bank  collective  investment  fund  acquiring  such
Certificate  pursuant to Section I of PTCE 91-38,  and in either  case,  no Plan
owns more than 10% of the  assets  of such  account  or  collective  fund  (when
aggregated with other Plans of the same employer (or its affiliates) or the same
employee  organization),   or  (D)  is  an  insurance  company  purchasing  such
Certificate  with funds  contained in an  "insurance  company  general  account"
(within the meaning of Section  V(e) of PTCE 95-60) and the purchase and holding
of  the  Certificate  are  covered  by  PTCE  95-60.  In  the  event  that  such
representation is violated, such transfer 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 either 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.

          If  the  Class  II-A-1  and  Class  II-A-2  Certificates  held  by the
Depositary are paid in full as a result of the Holder of the Class Y Certificate
having  exercised  the option  described  in Section  9.04,  the  Trustee  shall
execute,  countersign and deliver  Definitive  Certificates  for such Classes of
Certificates to or upon the order of the Holder of the Class Y Certificate,  and
the Class Y Certificate shall be cancelled by the Trustee.

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

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

     Section 5.04. Persons Deemed Owners.

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

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

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

     Section 5.06. Maintenance of Office or Agency.

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

                      THE DEPOSITOR AND THE MASTER SERVICER

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

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

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

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

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

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

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

     Section 6.04. Limitation on Resignation of the Master Servicer.

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

                                    DEFAULT

     Section 7.01. Events of Default.

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

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

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

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

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

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

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

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

     Section 7.02. Trustee to Act; Appointment of Successor.

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

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

     Section 7.03. Notification to Certificateholders.

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

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

                             CONCERNING THE TRUSTEE

     Section 8.01. Duties of the Trustee.

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

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

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

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

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

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

     Section 8.02. Certain Matters Affecting the Trustee.

          Except as otherwise provided in Section 8.01:

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

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

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

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

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

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

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

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

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

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

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

     Section 8.04. Trustee May Own Certificates.

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

     Section 8.05. Trustee's Fees and Expenses.

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

     Section 8.06. Eligibility Requirements for the Trustee.

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

     Section 8.07. Resignation and Removal of the Trustee.

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

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

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

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

     Section 8.08. Successor Trustee.

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

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

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

     Section 8.09. Merger or Consolidation of the Trustee.

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

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

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

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

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

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

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

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

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

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

     Section 8.11. Tax Matters.

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

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

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

     Section 8.12. Periodic Filings.

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

                                   TERMINATION

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

          Subject to Section 9.03, the obligations and  responsibilities  of the
Depositor,  the Master  Servicer and the Trustee  created hereby with respect to
the Trust Fund shall  terminate  upon the  earlier  of (a) the  purchase  by the
Master  Servicer of all  Mortgage  Loans (and REO  Properties)  remaining in the
Trust  Fund at the price  equal to the sum of (i) 100% of the  Stated  Principal
Balance of each Mortgage Loan 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 seven 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 not later  than the 10th day of the month  next  preceding  the month of
such final distribution. Any such notice shall specify (a) the Distribution Date
upon which final distribution on the Certificates will be made upon presentation
and surrender of Certificates at the office therein  designated,  (b) the amount
of such final  distribution,  (c) the  location of the office or agency at which
such  presentation  and  surrender  must be made,  and (d) that the Record  Date
otherwise applicable to such Distribution Date is not applicable,  distributions
being made only upon  presentation  and  surrender  of the  Certificates  at the
office  therein  specified.  The Master  Servicer  will give such notice to each
Rating Agency at the time such notice is given to Certificateholders.

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

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

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

     Section 9.03. Additional Termination Requirements.

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

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

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

          (b) The  Trustee  as agent for each 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.

     Section 9.04. Special Termination

          (a) (1) On any Distribution  Date occurring on or after the earlier of
(i) the Distribution  Date in May 2008 and (ii) the Distribution  Date occurring
immediately  after the Distribution Date on which the aggregate Stated Principal
Amount of the  Mortgage  Loans in Loan  Group 2 is less  than 20% of the  Stated
Principal  Balance of such Mortgage  Loans as of the Cut-off Date, the Holder of
the Class Y Certificate shall have the option to purchase all, but not less than
all,  of  the  Class  II-A-1  and  Class  II-A-2   Certificates  (the  "Purchase
Certificates") for a price equal to the outstanding Class Certificate Balance of
each  such   Certificate   plus  interest  accrued  thereon  at  the  applicable
Pass-Through  Rate and unpaid (the  "Acquisition  Price").  In order to exercise
such  option,  the  Class Y  Certificateholder  must,  no later  than the  fifth
Business Day of the calendar  month of such  Distribution  Date,  deliver to the
Trustee (i) written  notice,  in the form of Exhibit P hereto,  of its intent to
purchase all of the Purchase  Certificates and of the Distribution Date on which
it intends to do so and (ii) the Class Y Certificate.

          (2) On or before the Business Day preceding  such  Distribution  Date,
the Class Y  Certificateholder  shall  deposit cash in an amount  sufficient  to
provide for payment of the  Acquisition  Price.  Such amount  shall be deposited
into a segregated account  established by the Trustee and entitled  "Acquisition
Account - CWMBS, Inc. Mortgage  Pass-Through  Certificates,  Series 1998-F" (the
"Acquisition Account").  Such amounts deposited in the Acquisition Account shall
be paid by the Trustee to Holders of Purchase  Certificates  upon paydown of the
Purchase Certificates as provided below.

          (3) Notice of any  purchase of the Purchase  Certificates  pursuant to
the provisions of this subsection,  in the form of Exhibit Q hereto,  specifying
the  Distribution  Date upon which such purchase  shall be made,  shall be given
promptly  by the  Trustee  by  first  class  mail  to  Holders  of the  Purchase
Certificates  mailed no later than the eighth Business Day of the calendar month
of such  Distribution  Date. Such notice shall specify (A) the Distribution Date
upon which the  Acquisition  Price will be paid upon  transfer  of the  Purchase
Certificates (the "Acquisition Date"), (B) that the Acquisition Price applicable
to each Purchase Certificate  constitutes payment in full therefor,  and that no
further amounts in respect of interest or principal will be distributable to the
Holders   from   whom  such   Certificates   are   purchased   by  the  Class  Y
Certificateholder. The Trustee shall give such notice to the Master Servicer and
the  Certificate  Registrar  at the time such  notice is given to Holders of the
Purchase Certificates.

          (b) On the  Acquisition  Date, the Trustee shall (i) make payment from
the Acquisition Account to each Holder of a Purchase Certificate of the pro rata
portion  of  the  Acquisition  Price  attributable  to  such  Holder's  Purchase
Certificates  in the  manner in which  distributions  are  effected  under  this
Agreement, (ii) in accordance with this written notice received from the Class Y
Certificateholder  pursuant  to Section  9.04(a)(1),  execute,  countersign  and
deliver  upon  or to the  order  of the  Class Y  Certificateholder,  Definitive
Certificates  representing the Purchase  Certificates  registered in the name of
the Holder of the Class Y Certificate  or its nominee and (iii) cancel the Class
Y Certificate.

                            MISCELLANEOUS PROVISIONS

     Section 10.01. Amendment.

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

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

          This Agreement may also be amended from time to time by the Depositor,
the  Master  Servicer  and the  Trustee  with the  consent  of the  Holders of a
Majority  in  Interest of each Class of  Certificates  affected  thereby for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the  provisions of this Agreement or of modifying in any manner the rights of
the Holders of Certificates; provided, however, that no such amendment shall (i)
reduce in any manner the amount of, or delay the timing of, payments required to
be  distributed  on any  Certificate  without  the consent of the Holder of such
Certificate,  (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in (i),
without the consent of the Holders of Certificates of such Class evidencing,  as
to such  Class,  Percentage  Interests  aggregating  66%,  or (iii)  reduce  the
aforesaid  percentages  of  Certificates  the  Holders of which are  required to
consent to any such  amendment,  without  the consent of the Holders of all such
Certificates then outstanding.

          Notwithstanding any contrary provision of this Agreement,  the Trustee
shall not consent to any amendment to this Agreement  unless it shall have first
received an Opinion of  Counsel,  which  opinion  shall not be an expense of the
Trustee or the Trust Fund, to the effect that such  amendment will not cause the
imposition of any tax on 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 10.01 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent shall approve the substance thereof.  The
manner of obtaining  such consents and of evidencing  the  authorization  of the
execution  thereof by  Certificateholders  shall be  subject to such  reasonable
regulations as the Trustee may prescribe.

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

     Section 10.02. Recordation of Agreement; Counterparts.

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

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

     Section 10.03. Governing Law.

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

     Section 10.04. Intention of Parties.

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

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

     Section 10.05. Notices.

          (a) The Trustee shall use its best efforts to promptly  provide notice

          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.

          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,

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.

          Representations and Warranties of the Seller/Master Servicer
          ------------------------------------------------------------

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

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

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

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

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

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

                                  SCHEDULE III

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

             Representations and Warranties as to the Mortgage Loans
             -------------------------------------------------------

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

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

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

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

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

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

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

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

               (8) To the best of the Seller's knowledge,  no Mortgaged Property
     has been materially damaged by water, fire, earthquake,  windstorm,  flood,
     tornado  or similar  casualty  (excluding  casualty  from the  presence  of
     hazardous wastes or hazardous  substances,  as to which the Seller makes no
     representation)  so as  to  affect  adversely  the  value  of  the  related
     Mortgaged Property as security for such Mortgage Loan.

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

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

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

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

               (13)  To  the  best  of  the  Seller's  knowledge,   all  of  the
     improvements  which  were  included  for the  purpose  of  determining  the
     Appraised Value of the Mortgaged  Property lie wholly within the boundaries
     and building  restriction  lines of such property,  and no  improvements on
     adjoining  properties  encroach  upon the Mortgaged  Property,  unless such
     failure to be wholly within such boundaries and  restriction  lines or such
     encroachment,  as the case may be,  does not have a material  effect on the
     value of such Mortgaged Property.

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

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

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

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

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

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

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

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

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

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

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

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

               (26) No more than 0.16% of the Mortgage Loans in Loan Group 1 and
     0.65% of the  Mortgage  Loans in Loan  Group 2 (in each  case by  aggregate
     Stated  Principal  Balance of the Mortgage Loans in the related Loan Group)
     are Cooperative Loans.

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

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

         [No transfer of a Certificate of this Class shall be made unless such

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

registration in the name of an employee benefit plan subject to ERISA or
Section 4975 of the Code (or comparable provisions of any subsequent
enactments), or a trustee of any such plan or any other person acting on
behalf of any such plan, an Opinion of Counsel satisfactory to the Trustee and
the Master Servicer to the effect that the purchase or holding of such
Certificate will not result in the assets of the Trust Fund being deemed to be
"plan assets" and subject to the prohibited transaction provisions of ERISA
and the Code and will not subject the Trustee to any obligation in addition to
those undertaken in the Agreement, which Opinion of Counsel shall not be an
expense of the Trustee or the Master Servicer. [Such representation shall be
deemed to have been made to the Trustee by the Transferee's acceptance of a
Certificate of this Class and by a beneficial owner's acceptance of its
interest in a Certificate of this Class.] Notwithstanding anything else to the
contrary herein, any purported transfer of a Certificate of this Class to or
on behalf of an employee benefit plan subject to ERISA or to the Code without

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

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

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

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

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

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

                                  CWMBS, INC.
                      Mortgage Pass-Through Certificates

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

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

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

         Pursuant to the terms of the Agreement, a distribution will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing on
the first Distribution Date specified on the face hereof, to the Person in
whose name this Certificate is registered at the close of business on the
applicable Record Date in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Certificates of the Class to which this Certificate
belongs on such Distribution Date pursuant to the Agreement. The Record Date
applicable to each Distribution Date is the last Business Day of the month
next preceding the month of such Distribution Date.

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

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any
time by the Depositor, the Master Servicer and the Trustee with the consent of
the Holders of Certificates affected by such amendment evidencing the
requisite Percentage Interest, as provided in the Agreement. Any such consent
by the Holder of this Certificate shall be conclusive and binding on such
Holder and upon all future Holders of this Certificate and of any Certificate
issued upon the transfer hereof or in exchange therefor or in lieu hereof
whether or not notation of such consent is made upon this Certificate. The
Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

         As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register of the Trustee upon surrender of this Certificate for
registration of transfer at the Corporate Trust Office or the office or agency
maintained by the Trustee in New York, New York, accompanied by a written
instrument of transfer in form satisfactory to the Trustee and the Certificate
Registrar duly executed by the holder hereof or such holder's attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations and evidencing the same aggregate Percentage
Interest in the Trust Fund will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates
are exchangeable for new Certificates of the same Class in authorized
denominations and evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

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

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

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

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

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

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

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

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

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

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

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

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

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

                                                                  to EXHIBIT I

                              Certain Definitions

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

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

Interest in a Certificate, including the acquisition of a Certificate by the
Depositor.

         "Transferee": Any Person who is acquiring by Transfer any Ownership
Interest in a Certificate.

                       Section 5.02(c) of the Agreement

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

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

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

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

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

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