                  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

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

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 Buydown Agreement,
assumption, modification, written assurance or substitution agreement, if any;

                  (v) except as provided below, the original or duplicate

                             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 Investment  Account the portion
of such payment that is required to be  deposited  in the  Investment  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 delivered by the Seller
to the Master  Servicer for deposit in the  Investment  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 Seller shall promptly deliver to the Master  Servicer,  and
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 Seller or
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 capacity as Seller, 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) The Master Servicer, in its capacity as Master Servicer,
hereby makes the representations and warranties set forth in Schedule IV 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.

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

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

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

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

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

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

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

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

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

          Section 2.06.     Execution and Delivery of Certificates.

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

          Section 2.07.     REMIC Matters.

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

                                  ARTICLE III

                         ADMINISTRATION AND SERVICING
                               OF MORTGAGE LOANS

          Section 3.01.     Master Servicer to Service Mortgage Loans.

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

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

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

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

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

                  (c) As part of its servicing activities hereunder, the Master
Servicer, for the benefit of the Trustee and the Certificateholders, shall use
commercially 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  commercially  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
commercially  reasonable  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; Custodial
                           Accounts; Investment Account; Distribution Account.

                  (a) In accordance with and to the extent of the Servicing
Standard, the Master Servicer shall make commercially reasonable efforts in
accordance with the customary and usual standards of practice of prudent
mortgage servicers to collect all payments called for under the terms and
provisions of the Mortgage Loans to the extent such procedures shall be
consistent with this Agreement and the terms and provisions of any related
Required Insurance Policy. Consistent with the foregoing, the Master Servicer
may in its discretion (i) waive any late payment charge or any prepayment charge
or penalty interest in connection with the prepayment of a Mortgage Loan and
(ii) extend the due dates for payments due on a Mortgage Note for a period not
greater than 180 days from the first day it first became Delinquent; 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 Custodial Accounts for P&I and Custodial Accounts for Reserves, each of
which shall be an Eligible Account. The Servicer will be required under its
Servicing Agreement to deposit into the Custodial Account for P&I or the
Custodial Account for Reserves 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. Proceeds received for individual Mortgage
Loans from any title, hazard, or FHA insurance policy, VA guaranty, Primary
Insurance Policy or other insurance policy covering the Mortgage Loans shall be
deposited first in the Custodial Account for Reserves if required for the
restoration or repair of the related Mortgaged Property. Proceeds from those
insurance policies not deposited in the Custodial Account for Reserves shall be
deposited in the Custodial Account for P&I and shall be applied to the balances
of the related Mortgage Loans as payments of interest and principal. The
Servicer shall not be required to deposit in the Custodial Account for P&I or
the Custodial Account for Reserves payments or collections in the nature of
prepayment charges or late charges. The Master Servicer is hereby authorized to
make withdrawals from and to issue drafts against the Custodial Accounts for P&I
and the Custodial Accounts for Reserves for the purposes required or permitted
by this Agreement. Each Custodial Account for P&I and each Custodial Account for
Reserves shall bear a designation clearly showing the respective interests of
the applicable Servicer, as trustee, and of the Master Servicer, in
substantially one of the following forms:

                  (i) With respect to the Custodial Account for P&I: (i)
[Servicer's Name], as agent, trustee and/or bailee of principal and interest
custodial account for PNC Mortgage Securities Corp., its successors and assigns,
for various owners of interests in PNC Mortgage Securities Corp. mortgage-backed
pools or (ii) [Servicer's Name] in trust for PNC Mortgage Securities Corp.;

                  (ii) With respect to the Custodial Account for Reserves: (i)
[Servicer's Name], as agent, trustee and/or bailee of taxes and insurance
custodial account for PNC Mortgage Securities Corp., its successors and assigns
for various mortgagors and/or various owners of interests in PNC Mortgage
Securities Corp. mortgage-backed pools or (ii) [Servicer's Name] in trust for
PNC Mortgage Securities Corp. and various Mortgagors.

               (c) The Master Servicer shall establish and maintain, or cause
the Servicers to establish and maintain, Buydown Fund Accounts into which the
Master Servicer and the Servicers, as applicable, shall deposit the Buydown
Funds.

               (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 Investment Account
all funds held in the Custodial Account for P&I 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 Investment Account.

                  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 Investment Account.

                  (e) The Master Servicer shall establish and maintain an
Investment Account into which the Master Servicer shall deposit on a daily basis
within one Business Day of receipt, except as otherwise specifically provided
herein, the following payments and collections received by it in respect of
Mortgage Loans, and into which the Master Servicer shall transfer from the
Custodial Accounts for P&I, the Custodial Accounts for Reserves, and the Buydown
Fund Accounts, as appropriate, the following payments and collections deposited
into them by Servicers, 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 transferred from the related Buydown Fund Account into
the Investment 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 Investment  Account to withdraw such
amount from the  Investment  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 Investment  Account which  describes the amounts  deposited in
error in the Investment  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 Investment  Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.11.

                  At  its  option,   the  Master  Servicer  may  invest  funds
withdrawn  from the Custodial  Accounts for P&I, as well as any Buydown Funds,
Insurance Proceeds and Liquidation  Proceeds previously received by the Master
Servicer  for its own  account and at its own risk,  during any period  before
their deposit in the Distribution  Account.  Those funds shall  immediately be
deposited  by the  Master  Servicer  with  the  Investment  Depository  in the
Investment  Account for investment only as set forth in this Section 3.08. The
Master Servicer shall bear any losses  incurred on any  investments  made with
the  funds  and  shall  be  entitled  to  retain  all  gains  realized  on the
investments as additional servicing compensation.  Not later than the Business
Day before the Distribution  Date the Master Servicer shall deposit the funds,
net of any gains, in the Distribution Account.

                  (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 Investment 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 the Business Day next preceding the related Distribution Account
Deposit Date in the case of the Investment Account or the Business Day next
preceding the Distribution Date in the case of the Distribution Account (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 Account Deposit Date or Distribution Date, as the case
may be) 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
Investment 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 Investment 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 Investment
Account or paid to the Trustee for deposit into the Distribution Account, as
applicable.

                  (h) The Master Servicer shall give notice to the Trustee, the
Seller, each Rating Agency and the Depositor of any proposed change of the
location of the Investment 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 Investment
                            Account and the Distribution Account.

                  (a) The Master Servicer may from time to time make withdrawals
from the Investment 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 Investment 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 or the related 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 or the related Servicer
for (A) unreimbursed Servicing Advances, the right to reimbursement pursuant to
this clause (v)(A) with respect to any Mortgage Loan being limited to amounts
received on such Mortgage Loan(s) which represent late recoveries of the
payments for which such advances were made pursuant to Section 3.01 or Section
3.09 and (B) for unpaid Master Servicing Fees as provided in Section 3.14;

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

                  (vii) to pay itself reinvestment earnings deposited or earned
in the Investment Account to which it is entitled and 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 Investment
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 Investment 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  Investment  Account  pursuant  to such
subclauses (i), (ii),  (iv), (v) and (vi). Prior to making any withdrawal from
the Investment  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.

                  (c) The Master Servicer (or the applicable Servicer, if it
maintains a Buydown Fund Account) is authorized to make withdrawals from the
Buydown Fund Account or Custodial Account for P&I established by any Servicer
under its supervision of the following amounts of Buydown Funds:

                  (i) To deposit each month in the Investment Account the amount
necessary to supplement payments received on Buydown Loans;

                  (ii) Upon a Principal Prepayment in Full of any Mortgage Loan
having a related Buydown Fund, to apply amounts remaining in Buydown Fund
Accounts to reduce the required amount of the Principal Prepayment in Full (or,
if the Mortgagor has made a Principal Prepayment in Full, to refund the
remaining Buydown Fund amounts to the Person entitled to them);

                  (iii) Upon a foreclosure or liquidation of any Mortgage Loan
having a Buydown Fund, to deposit remaining Buydown Fund amounts in the
Investment Account as Liquidation Proceeds; and

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

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

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

                  (a) The Master Servicer shall use commercially 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 Investment 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. The Master Servicer shall not foreclose upon or otherwise comparably
convert a Mortgaged Property if it 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 if the Master Servicer is aware of evidence of toxic waste, other
hazardous substances or other evidence of environmental contamination on the
Mortgaged Property and in either case the Master Servicer determines that it
would be imprudent to do so. In connection with such a foreclosure or other
conversion, the Master Servicer shall cause to be followed practices and
procedures it deems appropriate and that are usual in general mortgage servicing
activities.

                  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 Investment  Account no later than the close
of business on each Determination  Date. The Master Servicer shall perform the
tax reporting and withholding  required by Sections 1445 and 6050J of the Code
with respect to foreclosures and abandonments,  the tax reporting  required by
Section  6050H of the Code with  respect to the receipt of  mortgage  interest
from individuals and, if required by Section 6050P of the Code with respect to
the cancellation of indebtedness by certain financial  entities,  by preparing
such tax and information returns as may be required, in the form required, and
delivering the same to the Trustee for filing.

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

                  The  decision  of the  Master  Servicer  to  foreclose  on a
defaulted  Mortgage  Loan shall be subject  to a  determination  by the Master
Servicer  that the  proceeds of such  foreclosure  would  exceed the costs and
expenses of bringing such a proceeding.  The income earned from the management
of any  REO  Properties,  net of  reimbursement  to the  Master  Servicer  for
expenses  incurred  (including any property or other taxes) in connection with
such management and net of unreimbursed Master Servicing Fees, Servicing Fees,
Advances,  Servicer Advances and Servicing  Advances,  shall be applied to the
payment of principal of and interest on the related  defaulted  Mortgage Loans
(with  interest  accruing as though such Mortgage Loans were still current and
adjustments, if applicable, to the Mortgage Rate were being made in accordance
with the terms of the Mortgage Note) and all such income shall be deemed,  for
all purposes in this  Agreement,  to be payments on account of  principal  and
interest  on the  related  Mortgage  Notes  and  shall be  deposited  into the
Investment  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  Investment  Account for any
Nonrecoverable  Advances (or portions thereof) that were previously  withdrawn
by the Master Servicer  pursuant to Section  3.11(a)(iii) that related to such
Mortgage Loan; third, to accrued and unpaid interest (to the extent no Advance
or  Servicer  Advance  has been made for such  amount or any such  Advance  or
Servicer  Advance has been  reimbursed)  on the  Mortgage  Loan or related REO
Property,  at the Adjusted Net Mortgage Rate to the Due Date  occurring in the
month in which such amounts are required to be distributed;  and fourth,  as a
recovery of principal of the Mortgage Loan. Excess Proceeds,  if any, from the
liquidation  of a  Liquidated  Mortgage  Loan will be  retained  by the Master
Servicer as additional servicing compensation pursuant to Section 3.17.

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

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

                  The Master Servicer shall deposit the Purchase Price for any
Modified  Mortgage Loan in the Investment  Account pursuant to Section 3.08(e)
within one  Business Day after the purchase of such  Modified  Mortgage  Loan.
Upon receipt by the Trustee of written notification of any such deposit signed
by a Servicing  Officer,  the Trustee shall release to the Master Servicer the
related  Mortgage  File and shall  execute and  deliver  such  instruments  of
transfer or assignment,  in each case without recourse,  as shall be necessary
to  vest  in  the  Master  Servicer  any  Modified  Mortgage  Loan  previously
transferred and assigned pursuant hereto.

                  The Master  Servicer  covenants  and agrees to indemnify the
REMIC against any and all liability for any "prohibited transaction" taxes and
any related interest, additions and penalties imposed on the REMIC established
hereunder as a result of any modification of a Mortgage Loan effected pursuant
to this subsection  (c), any holding of a Modified  Mortgage Loan by the REMIC
or any purchase of a Modified  Mortgage Loan by the Master  Servicer (but such
obligation  shall not  prevent the Master  Servicer  or any other  appropriate
Person from  contesting any such tax in appropriate  proceedings and shall not
prevent the Master Servicer from withholding payment of such tax, if permitted
by law,  pending the outcome of such  proceedings).  The Master Servicer shall
have no right of  reimbursement  for any amount paid pursuant to the foregoing
indemnification, except to the extent that the amount of any tax, interest and
penalties,  together  with interest  thereon,  is refunded to the REMIC or the
Master Servicer.

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

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

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

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

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

          Section 3.17.     Servicing Compensation.

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

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

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

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

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

          Section 3.18.     Annual Statement as to Compliance.

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

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

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

          Section 3.20.     Errors and Omissions Insurance; Fidelity Bonds.

                  The Master  Servicer  shall obtain and  maintain,  and shall
cause  each  Servicer  to  obtain  and  maintain,  (to  the  extent  generally
commercially  available  from  time to  time)  fidelity  bond and  errors  and
omissions  coverage  acceptable to FNMA or FHLMC regarding  their  obligations
under this Agreement and the applicable Servicing Agreement, respectively.

                               DISTRIBUTIONS AND
                        ADVANCES BY THE MASTER SERVICER

          Section 4.01.     Advances.

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

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

          Section 4.02.     Priorities of Distribution.

                  (a) The Trustee shall withdraw such Available Funds from the
Distribution Account and apply such funds to distributions on the specified
Classes of Senior Certificates in the following order and priority and, in each
case, to the extent of such funds remaining:

                  (i) to each interest-bearing Class of Senior Certificates, an
amount allocable to interest equal to the related Class Optimal Interest
Distribution Amount, any shortfall being allocated pro rata among such Classes
in proportion to the amount of the Class Optimal Interest Distribution Amount
that would have been distributed in the absence of such shortfall;

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                       (b) [Reserved];

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

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

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

          Section 4.03.     [Reserved]

          Section 4.04.     [Reserved]

          Section 4.05.     Allocation of Realized Losses.

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

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

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

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

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

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

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

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

          Section 4.06.     Monthly Statements to Certificateholders.

                       (a) Not later than each Distribution Date, the Trustee
shall prepare and cause to be forwarded by first class mail to each
Certificateholder, the Master Servicer, the Depositor and each Rating Agency a

                  Prepayments and Liquidation Proceeds included therein;

                         (ii) the amount thereof allocable to interest, any
                  Class Unpaid Interest Shortfall included in such distribution
                  and any remaining Class Unpaid Interest Shortfall after giving
                  effect to such distribution;

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

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

                         (v) the Pool Stated Principal Balance for the following
                  Distribution Date;

                         (vi) the Senior Percentage and Subordinated Percentage
                  for the following Distribution Date;

                         (vii) the amount of the Master Servicing Fees and
                  Servicing Fees paid to or retained by the Master Servicer and
                  the Servicers (with respect to the Servicers, in the
                  aggregate) with respect to such Distribution Date;

                         (viii) the Pass-Through Rate for each such Class of
                  Certificates with respect to such Distribution Date;

                         (ix) the amount of Advances included in the
                  distribution on such Distribution Date and the aggregate
                  amount of Advances outstanding as of the close of business on
                  such Distribution Date;

                         (x) the number and aggregate principal amounts of
                  Mortgage Loans (A) delinquent (exclusive of Mortgage Loans in
                  foreclosure) (1) 1 to 30 days (2) 31 to 60 days (3) 61 to 90
                  days and (4) 91 or more days and (B) in foreclosure and
                  delinquent (1) 1 to 30 days (2) 31 to 60 days (3) 61 to 90

                  the last day of the calendar month preceding such Distribution
                  Date;

                         (xi) for each of the preceding 12 calendar months, or
                  all calendar months since the Cut-off Date, whichever is less,

                  such Distribution Date and the date of acquisition thereof;

                         (xiii) the total number and principal balance of any

                  Amount, in each case as of the related Determination Date.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                               THE CERTIFICATES

          Section 5.01.     The Certificates.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

          Section 5.04.     Persons Deemed Owners.

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

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

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

          Section 5.06.     Maintenance of Office or Agency.

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

                     THE DEPOSITOR AND THE MASTER SERVICER

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

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

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

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

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

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

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

                  Section 6.05. Indemnification of Depositor and Seller. The
Master Servicer agrees to indemnify the Depositor and the Seller and each Person
who controls the Depositor or the Seller within the meaning of the Securities
Act against any claims, losses, damages, penalties, fines, forfeitures, legal
fees and related costs, judgments, and any other costs fees and expenses that
the trust, the Seller or the Depositor may sustain in any way related to the
failure of the Master Servicer to perform its obligations under this Agreement
to service the Mortgage Loans by reason of willful misfeasance, bad faith or
gross negligence in the performance of its duties or by reason of reckless
disregard of its obligations and duties hereunder. The Master Servicer agrees to
indemnify the Depositor and the Seller and each Person who controls the
Depositor or the Seller within the meaning of the Securities Act against any
claims, losses, damages, penalties, fines, forfeitures, legal fees and related
costs, judgments, and any other costs fees and expenses that the trust may
sustain in any way related to the breach of a representation or warranty under
Section 2.03(c).

                                    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 Distribution 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 (or such
                  longer period as is required so that three of the days are
                  Business 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 4.01,
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 Distribution  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
Investment  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 Investment Account by the Depositor or the Master Servicer.

          Section 8.04.     Trustee May Own Certificates.

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

          Section 8.05.     Trustee's Fees and Expenses.

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

          Section 8.06.     Eligibility Requirements for the Trustee.

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

          Section 8.07.     Resignation and Removal of the Trustee.

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

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

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

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

          Section 8.08.     Successor Trustee.

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

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

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

          Section 8.09.     Merger or Consolidation of the Trustee.

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

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

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

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

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

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

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

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

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

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

          Section 8.11.     Tax Matters.

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

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

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

          Section 8.12.     Periodic Filings.

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

                                  TERMINATION

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

                  Subject   to   Section    9.03,    the    obligations    and
responsibilities of the Depositor, the Master Servicer and the Trustee created
hereby with respect to the Trust Fund shall  terminate upon the earlier of (a)
the purchase by the Master Servicer of all Mortgage Loans (and REO Properties)
remaining  in the Trust Fund at the price  equal to the sum of (i) 100% of the
Stated  Principal  Balance of each Mortgage Loan (other than in respect of REO
Property) plus one month's accrued interest thereon at the applicable Adjusted
Mortgage  Rate and  (ii)  the  lesser  of (x) the  appraised  value of any REO
Property  as  determined  by the  higher of two  appraisals  completed  by two
independent  appraisers  selected by the Master Servicer at the expense of the
Master  Servicer and (y) the Stated  Principal  Balance of each  Mortgage Loan
related to any REO  Property,  in each case plus  accrued and unpaid  interest
thereon at the applicable  Adjusted Mortgage Rate and (b) the later of (i) the
maturity or other  liquidation  (or any Advance with  respect  thereto) of the
last Mortgage Loan remaining in the Trust Fund and the  disposition of all REO
Property  and (ii)  the  distribution  to  Certificateholders  of all  amounts
required to be  distributed  to them pursuant to this  Agreement.  In no event
shall the  trusts  created  hereby  continue  beyond  the  earlier  of (i) the
expiration  of 21 years from the death of the survivor of the  descendants  of
Joseph P.  Kennedy,  the late  Ambassador of the United States to the Court of
St. James's,  living on the date hereof and (ii) the Latest Possible  Maturity
Date.  The Master  Servicer may purchase all Mortgage Loans and REO Properties
pursuant to clause (a) above only if the Pool Stated Principal Balance, at the
time of any such  repurchase,  aggregates less than ten percent of the Cut-off
Date Pool Principal  Balance.  The purchase price for the Mortgage Loans shall
be deposited  in the  Investment  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 Master  Servicer  the related  Mortgage
File and shall execute and deliver such  instruments of transfer or assignment
prepared by the Master Servicer,  in either case without recourse, as shall be
necessary  to vest the  Mortgage  Loans in the Master  Servicer and the Master
Servicer shall succeed to all the Trustee's  right,  title and interest in and
to the Mortgage  Loans and all security and documents  related  thereto.  Such
assignment  shall be an assignment  outright and not for security.  The Master
Servicer  shall  thereupon  own  the  Mortgage  Loans,  and all  security  and
documents,   free  of  any   further   obligation   to  the   Trustee  or  the
Certificateholders with respect thereto.

          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  Investment  Account,  the Master
Servicer shall direct the Trustee promptly to send a final distribution notice
to each  Certificateholder.  If the Master  Servicer  elects to terminate  the
Trust Fund  pursuant to clause (a) of Section  9.01, at least 20 days prior to
the date notice is to be mailed to the affected  Certificateholders the Master
Servicer  shall  notify the  Depositor  and the Trustee of the date the Master
Servicer intends to terminate the Trust Fund and of the applicable  repurchase
price of the Mortgage Loans and REO Properties.

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

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

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

          Section 9.03.     Additional Termination Requirements.

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

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

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

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

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

                           MISCELLANEOUS PROVISIONS

          Section 10.01.    Amendment.

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

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

                  Notwithstanding  any contrary  provision of this  Agreement,
the Trustee  shall not consent to any  amendment to this  Agreement  unless it
shall have first received an Opinion of Counsel, which opinion shall not be an
expense of the  Trustee or the Trust Fund,  to the effect that such  amendment
will   not   cause   the   imposition   of  any  tax  on  the   REMIC  or  the
Certificateholders  or cause  the REMIC to fail to  qualify  as a REMIC at any
time that any Certificates are outstanding.

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

                  It   shall   not   be   necessary   for   the   consent   of
Certificateholders  under this Section 10.01 to approve the particular form of
any proposed  amendment,  but it shall be  sufficient  if such  consent  shall
approve the substance  thereof.  The manner of obtaining  such consents and of
evidencing the  authorization of the execution  thereof by  Certificateholders
shall be subject to such reasonable regulations as the Trustee may prescribe.

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

          Section 10.02.    Recordation of Agreement; Counterparts.

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

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

          Section 10.03.    Governing Law.

                  THIS  AGREEMENT  SHALL BE CONSTRUED IN  ACCORDANCE  WITH AND
GOVERNED BY THE 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,  WITHOUT  GIVING  EFFECT TO  CONFLICT  OF LAWS
PRINCIPLES.

          Section 10.04.    Intention of Parties.

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

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

          Section 10.05.    Notices.

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

                         1. Any material change or amendment to this Agreement;

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

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

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

                         5. The final payment to Certificateholders.

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

                              1. Each report to Certificateholders described in
                       Section 4.06;

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

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

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

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

prepaid, to their respective addresses appearing in the Certificate Register.

          Section 10.06.    Severability of Provisions.

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

          Section 10.07.    Assignment.

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

          Section 10.08.    Limitation on Rights of Certificateholders.

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

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

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

          Section 10.09.    Inspection and Audit Rights.

                  The Master Servicer agrees that, on reasonable prior notice,
it will permit and will cause each  Servicer to permit any  representative  of
the Seller,  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 Seller, 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 Seller,
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 Servicer.

          Section 10.10.    Certificates Nonassessable and Fully Paid.

                  It is the intention of the Depositor that Certificateholders
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.

                  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

                           (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  perform  any  of its
         obligations  under the Pooling and Servicing  Agreement in accordance
         with the terms thereof.

                           (2)  IndyMac  has  the  full  corporate  power  and
         authority to sell 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 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 1999-B


            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,
PNC Mortgage Securities Corp., as 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 1.20% of the  Mortgage  Loans (by
         aggregate  Stated  Principal  Balance  of  the  Mortgage  Loans)  are
         Cooperative Loans.

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

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

         transact  any  and  all  business  contemplated  by the  Pooling  and
         Servicing  Agreement  to be  conducted by PNC 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,

         obligations  under the Pooling and Servicing  Agreement in accordance
         with the terms thereof.

                           (2) PNC has the full corporate  power and authority
         to service each Mortgage Loan,  and to execute,  deliver and perform,

         necessary corporate action on the part of PNC 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 PNC, enforceable
         against  PNC 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 PNC, the  servicing of the Mortgage  Loans by
         PNC 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 PNC and will
         not (A) result in a material  breach of any term or  provision of the
         charter or by-laws of PNC 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 PNC is a party or by which it may be  bound,  or
         (C)  constitute  a  material  violation  of  any  statute,  order  or
         regulation   applicable  to  PNC  of  any  court,   regulatory  body,
         administrative  agency or governmental body having  jurisdiction over
         PNC; and PNC 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 PNC'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
         PNC's  knowledge,  threatened  against  PNC that would  prohibit  the
         execution  or  delivery  of, or  performance  under,  the Pooling and
         Servicing Agreement by PNC.
