Class I-A-R  Certificates  will  represent  the residual  interests in the Lower
REMIC and Upper  REMIC,  as  described  in Section  2.7.  The  "latest  possible
maturity  date" for federal  income tax purposes of all REMIC regular  interests
created hereby will be the Latest Possible Maturity Date.

         The following  table sets forth  characteristics  of the  Certificates,
together with the minimum denominations and integral multiples in excess thereof
in which such Classes  shall be issuable  (except that one  Certificate  of each

                           with  the  rating  of  the  Certificates,  a  written
                           commitment or interim binder or preliminary report of

                           lieu thereof,  an Alternative Title Product or a copy
                           of such  Alternative  Title Product  certified by the
                           Seller  as  being  a true  and  complete  copy of the
                           Alternative Title Product; and

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

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

                           (B)      The executed Security Agreement;

                           (C)      The executed Proprietary Lease;

                           (D)      The executed Recognition Agreement;

                           (E)      The executed 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 Coop Shares and
                                    the Proprietary Lease; and

                           (F)      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 that is not a
MERS  Mortgage  Loan the  Depositor  cannot  deliver (a) the  original  recorded
Mortgage or (b) all interim recorded assignments  satisfying the requirements of
clause (ii) or (iii) above,  respectively,  concurrently  with the execution and
delivery  hereof  because such document or documents have not been returned from
the applicable public recording office,  the Depositor shall promptly deliver or
cause to be  delivered  to the  Trustee  or the  Custodian  on its  behalf  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 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;  provided,  however,  in the event the  Depositor  is unable to deliver or
cause  to be  delivered  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  or  cause to be
delivered  such  documents  to the  Trustee  or the  Custodian  on its behalf 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 or the  Custodian on its behalf (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 and the  public  recording  office  requires  the  presentation  of a "lost
instruments affidavit and indemnity" or any equivalent document,  because only a


                                      -36-
<PAGE>

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 Depositor  shall deliver or cause to be delivered to the Trustee or
the  Custodian  on its behalf a copy of such  Mortgage  certified by such public
recording  office  to be a true  and  complete  copy  of the  original  recorded
Mortgage.

         In addition, in the event that in connection with any Mortgage Loan the
Depositor  cannot  deliver or cause to be  delivered  the  original or duplicate
original  lender's title policy (together with all riders  thereto),  satisfying
the  requirements  of clause  (v) above,  concurrently  with the  execution  and
delivery  hereof  because the related  Mortgage has not been  returned  from the
applicable  public  recording  office,  the Depositor shall promptly  deliver or
cause to be  delivered  to the  Trustee  or the  Custodian  on its  behalf  such
original or duplicate  original  lender's title policy (together with all riders
thereto) upon receipt thereof from the applicable title insurer, but in no event
shall any such  delivery of the original or duplicate  original  lender's  title
policy  be made  later  than one year  following  the  Closing  Date;  provided,
however,  in the  event  the  Depositor  is  unable  to  deliver  or cause to be
delivered by such date the original or duplicate  original lender's title policy
(together  with all riders  thereto)  because the related  Mortgage has not been
returned by the  appropriate  recording  office,  the Depositor shall deliver or
cause to be  delivered  such  documents  to the Trustee or the  Custodian on its
behalf as promptly as possible  upon receipt  thereof and, in any event,  within
720 days  following  the  Closing  Date;  provided  further,  however,  that the
Depositor  shall not be required to deliver an  original or  duplicate  lender's
title policy  (together  with all riders  thereto) if the Depositor  delivers an
Alternative  Title Product in lieu thereof.  Notwithstanding  the preceding,  in
connection  with any  Mortgage  Loan for which  either the original or duplicate
original title policy has not been delivered to the Trust, if at any time during
the term of this Agreement the parent company of the Seller does not have a long
term senior debt rating of A- or higher from S&P and A- or higher from Fitch (if
rated by Fitch),  then the Depositor shall within 30 days deliver or cause to be
delivered  to  the  Trustee  or  the  Custodian  on its  behalf  (if it has  not
previously done so) a written commitment or interim binder or preliminary report
of the title issued by the title insurance or escrow company with respect to the
Mortgaged Property.

         Subject  to  the  immediately   following  sentence,   as  promptly  as
practicable subsequent to such transfer and assignment, and in any event, within
thirty  (30) days  thereafter,  the  Master  Servicer  shall (i)  complete  each
assignment  of  Mortgage,  as  follows:  "First  Horizon  Mortgage  Pass-Through
Certificates, Series 2005-AA10, The Bank of New York, as trustee for the holders
of the  Certificates",  (ii)  cause  such  assignment  to be in proper  form for
recording in the appropriate  public office for real property  records and (iii)
cause to be delivered  for recording in the  appropriate  public office for real
property  records the assignments of the Mortgages to the Trustee,  except that,
with respect to any  assignments of Mortgage as to which the Master Servicer has
not received the  information  required to prepare such assignment in recordable
form, the Master Servicer's obligation to do so and to deliver the same for such
recording shall be as soon as practicable  after receipt of such information and
in any event within thirty (30) days after receipt thereof.  Notwithstanding the
foregoing,  the Master  Servicer  need not cause to be recorded  any  assignment
which  relates  to a  Mortgage  Loan  in  any  state  other  than  the  Required
Recordation States.


                                      -37-
<PAGE>

         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 or the Custodian on its behalf,  will deposit in the Certificate Account
the portion of such payment that is required to be deposited in the  Certificate
Account pursuant to Section 3.8 hereof.

         Notwithstanding  anything  to the  contrary in this  Agreement,  within
thirty days after the Closing Date,  the  Depositor  shall either (i) deliver or
cause to be delivered to the Trustee or the Custodian on its behalf the Mortgage
File as required  pursuant to this Section 2.1 for each Delay Delivery  Mortgage
Loan or (ii) (A)  substitute or cause to be  substituted  a Substitute  Mortgage
Loan for the  Delay  Delivery  Mortgage  Loan or (B)  repurchase  or cause to be
repurchased the Delay Delivery  Mortgage Loan, which  substitution or repurchase
shall be  accomplished  in the manner and subject to the conditions set forth in
Section 2.3 (treating  each Delay Delivery  Mortgage Loan as a Deleted  Mortgage
Loan for purposes of such Section 2.3), provided, however, that if the Depositor
fails to deliver a Mortgage File for any Delay Delivery Mortgage Loan within the
thirty-day  period provided in the prior  sentence,  the Depositor shall use its
best reasonable efforts to effect or cause to be effected a substitution, rather
than a repurchase of, such Deleted  Mortgage Loan and provided  further that the
cure period provided for in Section 2.2 or in Section 2.3 shall not apply to the
initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan, but
rather the  Depositor  shall have five (5) Business  Days to cure or cause to be
cured such failure to deliver. At the end of such thirty-day period, the Trustee
or the Custodian,  on its behalf shall send a Delay Delivery  Certification  for
the Delay Delivery  Mortgage Loans delivered  during such  thirty-day  period in
accordance with the provisions of Section 2.2.  Notwithstanding  anything to the
contrary  contained in this  Agreement,  none of the Mortgage Loans in the Trust
Fund is or will be Delay Delivery Mortgage Loans.

         SECTION 2.2 Acceptance by Trustee of the Mortgage Loans.

         The Trustee or the  Custodian,  on behalf of the Trustee,  acknowledges
receipt of the  documents  identified in the Initial  Certification  in the form
annexed hereto as Exhibit E and declares that it or the Custodian holds and will
hold such documents and the other documents delivered to it or the Custodian, as
applicable,  constituting the Mortgage Files,  and that it or the Custodian,  as
applicable,  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 the Custodian will maintain
possession  of the  Mortgage  Notes in the  State  of  Texas,  unless  otherwise
permitted by the Rating Agencies.

         The Trustee  agrees to execute and deliver or to cause the Custodian to
execute and deliver on the Closing Date to the Depositor and the Master Servicer
an Initial  Certification  in the form annexed hereto as Exhibit E. Based on its
or the  Custodian's  review  and  examination,  and  only  as to  the  documents
identified  in such  Initial  Certification,  the  Custodian,  on  behalf of the
Trustee,  acknowledges  that such  documents  appear  regular  on their face and
relate to such Mortgage  Loan.  Neither the Trustee nor the  Custodian  shall be
under any 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.


                                      -38-
<PAGE>

         On or about  the  thirtieth  (30th)  day after the  Closing  Date,  the
Trustee  shall  deliver or shall cause the Custodian to deliver to the Depositor
and the  Master  Servicer a Delay  Delivery  Certification  in the form  annexed
hereto  as   Exhibit  F,  with  any   applicable   exceptions   noted   thereon.
Notwithstanding  anything to the contrary  contained in this Agreement,  none of
the  Mortgage  Loans in the  Trust  Fund is or will be Delay  Delivery  Mortgage
Loans.

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

         If, in the course of such  review,  the  Trustee or the  Custodian,  on
behalf of the Trustee, finds any document constituting a part of a Mortgage File
which does not meet the  requirements  of Section 2.1, the Trustee shall list or
shall  cause  the  Custodian  to list  such as an  exception  in the  Subsequent
Certification;  provided,  however  that  neither the Trustee nor the  Custodian
shall 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
2.3, 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 or shall cause the Custodian to 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 or the Custodian on its behalf.
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 2.5 hereof, if any, and any substitution pursuant to
(a) above shall not be effected prior to the additional  delivery to the Trustee
of a Request for Release substantially in the form of Exhibit L. No substitution
is permitted to be made in any calendar month after the  Determination  Date for
such month.  The Purchase Price for any such Mortgage Loan shall be deposited by
the Seller in the Certificate  Account on or prior to the  Distribution  Account
Deposit  Date for the  Distribution  Date in the  month  following  the month of
repurchase  and,  upon  receipt of such deposit and  certification  with respect
thereto in the form of Exhibit M hereto,  the Trustee  shall cause the Custodian
to release the related Mortgage File to the Seller and shall execute and deliver


                                      -39-
<PAGE>

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. If pursuant to the foregoing  provisions the Seller repurchases
a Mortgage Loan that is a MERS Mortgage Loan,  the Master  Servicer shall either
(i)  cause  MERS to  execute  and  deliver  an  assignment  of the  Mortgage  in
recordable form to transfer the Mortgage from MERS to the Seller and shall cause
such  Mortgage  to be  removed  from  registration  on  the  MERS(R)  System  in
accordance  with MERS' rules and  regulations or (ii) cause MERS to designate on
the MERS(R) System the Seller as the beneficial holder of such Mortgage Loan.

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

         It is  understood  and  agreed  that the  obligation  of the  Seller to
substitute  for or to  purchase  any  Mortgage  Loan  which  does  not  meet the
requirements  of Section 2.1 above shall  constitute the sole remedy  respecting
such defect  available to the Trustee,  the Depositor and any  Certificateholder
against the Seller.

         The  mortgage  loans  permitted  by the terms of this  Agreement  to be
included  in the Trust Fund are  limited to (i) the  Mortgage  Loans  (which the
Depositor   acquired   pursuant  to  MLPA  II,  which   contains,   among  other
representations and warranties, a representation and warranty of the Seller that
no  Mortgage  Loan is a "high cost loan" as defined by the  specific  applicable
local,  state or federal predatory and abusive lending laws, and (ii) Substitute
Mortgage Loans (which, by definition as set forth in this Agreement and referred
to in MLPA I, are  required  to conform  to,  among  other  representations  and
warranties, a representation and warranty of the Seller set forth in MLPA I that
no  Substitute  Mortgage  Loan is a "high cost loan" as defined by the  specific
applicable  local,  state or federal  predatory and abusive lending laws). It is
therefore  understood  and agreed by the parties  hereto that it is not intended
that any Mortgage  Loan be included in the Trust Fund that is a "high cost loan"
as defined in the by the specific  applicable local,  state or federal predatory
and abusive lending laws.

         SECTION 2.3  Representations  and  Warranties  of the Master  Servicer;
Covenants of the Seller.

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

         (b)      Upon  discovery by any of the parties  hereto of a breach of a
                  representation or warranty made pursuant to Schedule B to MLPA
                  I 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


                                      -40-
<PAGE>

                  from any party of a breach of any  representation  or warranty
                  made  pursuant  to Schedule B to MLPA I which  materially  and
                  adversely affects the interests of the  Certificateholders  in
                  any Mortgage  Loan,  it shall cure such breach in all material
                  respects,  and if such breach is not so cured,  shall,  (i) if
                  such 90-day period expires prior to the second  anniversary of
                  the  Closing  Date,  remove  such  Mortgage  Loan (a  "Deleted
                  Mortgage  Loan")  from the Trust  Fund and  substitute  in its
                  place a Substitute Mortgage Loan, in the manner and subject to
                  the conditions set forth in this Section;  or (ii)  repurchase
                  the affected  Mortgage Loan or Mortgage Loans from the Trustee
                  at the Purchase Price in the manner set forth below; provided,
                  however,  that any such  substitution  pursuant  to (i)  above
                  shall not be effected  prior to the delivery to the Trustee of
                  the Opinion of Counsel required by Section 2.5 hereof, if any,
                  and any such  substitution  pursuant to (i) above shall not be
                  effected  prior to the  additional  delivery to the Trustee or
                  the   Custodian  on  its  behalf  of  a  Request  for  Release
                  substantially  in the form of Exhibit M and the Mortgage  File
                  for any  such  Substitute  Mortgage  Loan.  The  Seller  shall
                  promptly reimburse the Master Servicer and the Trustee for any
                  expenses  reasonably  incurred  by the Master  Servicer or the
                  Trustee in respect of enforcing  the remedies for such breach.
                  With respect to the representations  and warranties  described
                  in this  Section  which  are made to the best of the  Seller's
                  knowledge,  if it is discovered by either the  Depositor,  the
                  Seller   or  the   Trustee   that   the   substance   of  such
                  representation  and warranty is inaccurate and such inaccuracy
                  materially  and  adversely  affects  the value of the  related
                  Mortgage  Loan  or the  interests  of  the  Certificateholders
                  therein,  notwithstanding  the Seller's lack of knowledge with
                  respect to the substance of such  representation  or warranty,
                  such  inaccuracy  shall be deemed a breach  of the  applicable
                  representation or warranty.

         With respect to any Substitute Mortgage Loan or Loans, the Seller shall
deliver to the  Trustee or the  Custodian  on its behalf 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
2.1, with the Mortgage  Note  endorsed and the Mortgage  assigned as required by
Section 2.1. 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 Schedule B to
MLPA I with respect to such Mortgage Loan.  Upon any such  substitution  and the
deposit  to the  Certificate  Account  of the amount  required  to be  deposited
therein in  connection  with such  substitution  as described  in the  following
paragraph, the Trustee shall release or shall cause the Custodian to release the


                                      -41-
<PAGE>

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 2.3.

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

         In the event that the Seller shall have  repurchased  a Mortgage  Loan,
the  Purchase  Price  therefor  shall be deposited  in the  Certificate  Account
pursuant to Section 3.5 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  2.5 and  receipt of a Request  for  Release in the form of
Exhibit M hereto,  the Trustee  shall  release or shall cause the  Custodian  to
release the related Mortgage File held for the benefit of the Certificateholders
to such  Person,  and the Trustee  shall  execute and deliver or shall cause the
Custodian to 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 the  Seller  to  cure,
repurchase or replace any Mortgage Loan as to which a breach has occurred and is
continuing shall  constitute the sole remedy against the Seller  respecting such
breach  available to  Certificateholders,  the Depositor or the Trustee on their
behalf.

         After giving effect to the sale of the Certificates by the Depositor to
the Underwriter, and thereafter, so long as any Certificates remain outstanding,
the Seller, its affiliates and agents, collectively,  shall not beneficially own
Certificates  the aggregate  fair value of which would  represent 90% or more of
the beneficial interests in the Trust Fund.

         The  representations  and warranties  made pursuant to this Section 2.3
shall survive  delivery of the  respective  Mortgage Files to the Trustee or the
Custodian for the benefit of the Certificateholders.

         SECTION 2.4  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 pursuant to MLPA II and  immediately  prior to the conveyance of the
Mortgage  Loans by it to the Trustee  pursuant  to Section  2.1(a)  hereof,  the
Depositor  had good  title to the  Mortgage  Loans and the  Mortgage  Notes were
subject to no offsets, defenses or counterclaims.

         It is understood and agreed that the representations and warranties set
forth in this Section 2.4 shall  survive  delivery of the Mortgage  Files to the
Trustee.  Upon  discovery by the  Depositor or the Trustee of a breach of any of
the  foregoing  representations  and  warranties  set forth in this  Section 2.4
(referred  to herein as a  "breach"),  which  breach  materially  and  adversely
affects  the  interest of the  Certificateholders,  the party  discovering  such
breach shall give prompt written notice to the others and to each Rating Agency.

         SECTION  2.5  Delivery  of  Opinion  of  Counsel  in  Connection   with
Substitutions.

         (a)      Notwithstanding  any contrary provision of this Agreement,  no
                  substitution  pursuant  to Section 2.2 or Section 2.3 shall be
                  made  more than 90 days  after the  Closing  Date  unless  the
                  Depositor 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 any REMIC  created  hereunder to fail to qualify
                  as a REMIC at any time that any Certificates are outstanding.

         (b)      Upon  discovery by the Depositor,  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 Depositor
                  to cause the Seller,  pursuant  to MLPA I and at the  Seller's
                  option, to either (i) substitute, if the conditions in Section
                  2.3(b)  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  2.3.  The Trustee  shall  reconvey or shall cause the
                  Custodian  to 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 2.3.

         SECTION 2.6 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 2.7 REMIC Matters.

         The  Preliminary  Statement  sets forth the "latest  possible  maturity
date" for federal  income tax purposes of all REMIC  regular  interests  created
hereby.

         The assets of the Lower REMIC  shall be as set forth in the  definition
thereof.  Each  interest  identified  in the first table below by a  designation
beginning with "L" shall be a "regular  interest" in the Lower REMIC and a Lower
REMIC  Interest,  and the RL  Interests  shall  be the sole  class  of  residual
interest in the Lower REMIC.  The Lower REMIC Interests shall be  uncertificated
and shall be held by the Trustee as assets of the Upper REMIC.

         The assets of the Upper REMIC  shall be as set forth in the  definition
thereof.  The Regular  Certificates shall represent  "regular  interests" in the
Upper REMIC. The RU Interest shall be the sole class of residual interest in the
Upper REMIC.  The Class I-A-R  Certificate  shall represent  ownership of the RL
Interest and RU Interest.

         The "Startup Day" for purposes of the REMIC  Provisions  for each REMIC
hereunder shall be the Closing Date. The Tax Matters Person with respect to each
REMIC  hereunder shall be the Trustee and the Trustee shall hold the Tax Matters
Person Certificate. Each REMIC's taxable year shall be the calendar year and its
accounts shall be maintained using the accrual method.

----------
(1)   The Lower REMIC Interest  L-I-A-1,  Lower REMIC Interest L-I-A-2 and Lower
      REMIC Interest  L-I-A-ZZZ shall be Corresponding  Classes to these Classes
      of  Certificates:  I-A-1,  I-A-2,  I-A-R,  B-1, B-2, B-3, B-4, B-5 and B-6
      (provided that with respect to B-1, B-2, B-3, B-4, B-5 and B-6, such Lower
      REMIC Interests shall only correspond to the portion supported by Pool I).
      The Lower REMIC  Interest  L-II-A-1,  Lower REMIC L-II-A-2 and Lower REMIC
      Interest  L-II-A-ZZZ  shall be  Corresponding  Classes to these Classes of
      Certificates:  II-A-1, B-1, B-2, B-3, B-4, B-5 and B-6 (provided that with
      respect to B-1, B-2,  B-3,  B-4, B-5 and B-6,  such Lower REMIC  Interests
      shall only correspond to the portion supported by Pool II). .
(2)   The Lower  REMIC  Interest  Rate for the  Lower  REMIC  Interest  L-I-A-1,
      L-I-A-2  and  L-I-A-ZZZ  will  equal the  Weighted  Average  Adjusted  Net
      Mortgage Rate for Pool I.
(3)   The Lower  REMIC  Interest  Rate for the Lower  REMIC  Interest  L-II-A-1,
      L-II-A-2  and  L-II-A-ZZZ  will equal the  Weighted  Average  Adjusted Net
      Mortgage Rate for Pool II.

         "L1  Interests"  refers to the  L-I-A-1  Lower REMIC  Interest  and the
L-II-A-1 Lower REMIC Interests. "L2 Interests" refers to the L-I-A-2 Lower REMIC
Interest and L-II-A-2 Lower REMIC Interest. "LZZZ Interests" refers to L-I-A-ZZZ
Lower REMIC Interest and L-II-A-ZZZ Lower REMIC Interest. Each L1 Interest shall
have a principal balance initially equal to 0.9% of the Group Subordinate Amount
of its  corresponding  Mortgage  Pool.  Each L2 Interest  shall have a principal
balance  initially  equal  to  0.1%  of  the  Group  Subordinate  Amount  of its
corresponding Mortgage Pool. The initial principal balance of each LZZZ Interest
shall  equal  the  excess of the Pool  Principal  Balance  of its  corresponding
Mortgage Pool over the sum of the initial principal balances of the L1 Interests
and L2 Interests corresponding to such Mortgage Pool.

         Unless a Cross-over Situation (as defined below) exists,  principal and
Realized  Losses  arising with respect to each  Mortgage Pool shall be allocated
first to cause the L1 and L2 Interests  corresponding  to such  Mortgage Pool to
equal 0.9% and 0.1% of the Group Subordinate  Amount of such Mortgage Pool as of
such  Distribution  Date (after  distributions  of principal  and  allocation of
Realized Losses are made) and all excess  principal and Realized Losses shall be
allocated to the LZZZ Interest  corresponding to such Mortgage Pool. A L1, L2 or
LZZZ Interest that is allocated principal on any Distribution Date shall receive
such  principal,  and have its principal  balance  reduced by the amount of such
principal,  on such Distribution Date. Similarly, a L1, L2 or LZZZ Interest that
is allocated a Realized Loss on any  Distribution  Date shall have its principal
balance reduced by the amount of such Realized Loss on such Distribution Date.

         A  "Cross-over  Situation"  exists if on any  Distribution  Date (after
taking into account  distributions  of  principal  and  allocations  of Realized
Losses on such Distribution  Date) the L1 and L2 Interests  corresponding to any
Mortgage Pool are in the aggregate less than 1% of the Group Subordinate  Amount
of the  corresponding  Mortgage  Pool. If a Cross-over  Situation  exists on any
Distribution  Date, and the weighted average interest rate of the outstanding L1
and L2 Interests is less than the Pass-Through Rate for any Class of Subordinate
Certificates  for the  following  Distribution  Date,  a Principal  Reallocation
Payment (as defined below) shall be made  proportionately  to the outstanding L1
Interests prior to any other  distributions of principal from each such Mortgage
Pool so that the Calculation Rate equals the Pass-Through Rate for each Class of
Subordinate  Certificates.  If a Cross-over Situation exists on any Distribution
Date,  and the weighted  average rate of the  outstanding L1 and L2 Interests is
greater than the Pass-Through Rate for any Class of Subordinate Certificates for
the following  Distribution Date, a Principal Reallocation Payment shall be made
proportionately to the outstanding L2 Interests prior to any other distributions
of principal  from each such Mortgage Pool so that the  Calculation  Rate equals
the Pass-Through Rate for each Class of Subordinate  Certificates.  A "Principal
Reallocation  Payment" is a distribution of the minimum amount of principal that


                                      -45-
<PAGE>

causes the  Calculation  Rate (as defined below) with respect to the outstanding
L1 and L2 Interests to equal the Pass-Through Rate for each Class of Subordinate
Certificates.  The "Calculation Rate" shall equal the product of (i) 10 and (ii)
the weighted  average  interest  rate of the  outstanding  L1 and L2  Interests,
treating each L1 Interest as capped at zero or reduced by a fixed  percentage of
100% of the interest  accruing on such class.  Principal  Reallocation  Payments
shall be made from principal received on the Mortgage Loans from a Mortgage Pool
and shall also consist of a proportionate allocation of Realized Losses from the
Mortgage Loans of a Mortgage Pool. For purposes of making Principal Reallocation
Payments,  to the extent  that the  principal  received  during  the  applicable
collection period from the related Mortgage Pool and related Realized Losses are
insufficient to make the necessary  reduction of principal,  then interest shall
accrue  on the LZZZ  Interest  (and be added to its  principal  balance)  of the
related Mortgage Pool to allow the necessary Principal  Reallocation  Payment to
be made. The Calculation Rate is designed to always equal the Pass-Through  Rate
of each Class of Subordinated Certificates.

         If a Cross-over  Situation exists, the aggregate  principal balances of
the  outstanding  L1 and L2 Interests of all of the Mortgage  Pools shall not be
reduced below one percent of the aggregate Pool Principal  Balance of all of the
Mortgage  Pools for the  following  Distribution  Date in  excess of the  Senior
Certificates  as of the related  Distribution  Date (after  taking into  account
distributions   of  principal  and   allocations  of  Realized  Losses  on  such
Distribution  Date). To the extent this limitation  prevents the distribution of
principal  to the L1 and L2  Interests  of a Mortgage  Pool and the related LZZZ
Interest  has already  been  reduced to zero,  such excess  principal  from such
Mortgage  Pool  shall  be paid  proportionately  to the  LZZZ  Interests  of the
Mortgage  Pool or Pools whose  aggregate L1 and L2  Interests  are less than one
percent of the Group Subordinate  Amount.  Any such shortfall as a result of the
Mortgage Pool receiving the extra payment having a Weighted Average Adjusted Net
Mortgage Rate lower than the Weighted  Average Adjusted Net Mortgage Rate of the
Mortgage  Pool from  which the  payment  was  reallocated  shall be treated as a
Realized Loss and if excess arises as result of the Mortgage Pool  receiving the
extra payment having a Weighted  Average  Adjusted Net Mortgage Rate higher than
the Mortgage Pool from which the payment was  reallocated it shall reimburse the
Upper REMIC for prior  Realized  Losses.  If on any  Distribution  Date,  the L1
Interest or L2 Interest  remains  outstanding  after the related Pool  Principal
Balance is at zero as of the beginning of the Accrual  Period  corresponding  to
such  Distribution  Date,  their Lower REMIC Interest Rate shall be the Weighted
Average Adjusted Net Mortgage Rate of the Mortgage Pool with the lowest Weighted
Average  Adjusted Net Mortgage Rate that remains  outstanding  and the excess of
interest  at the  Pass-Through  Rate  for  the  Subordinated  Certificates  over
interest at such Weighted Average Adjusted Net Mortgage Rate shall be treated as
paid from Lower REMIC to the Upper  REMIC as  reimbursement  for prior  Realized
Losses.

         The foregoing REMIC structure is intended to cause all of the cash from
the  Mortgage  Loans to flow  through to the Upper REMIC as cash flow on a REMIC
regular interest, without creating any shortfall-actual or potential (other than
for  credit  losses)  to any REMIC  regular  interest.  To the  extent  that the
structure is believed to diverge from such  intention  the Trustee shall resolve
ambiguities to accomplish such result and shall to the extent necessary  rectify
any  drafting   errors  or  seek   clarification   to  the   structure   without
Certificateholder  approval (but with  guidance of counsel) to  accomplish  such
intention.

         SECTION 2.8 Covenants of the Master Servicer.

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

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

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

                                   ARTICLE III
                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

         SECTION 3.1 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 (i)
the Servicing  Rights  Transfer and  Subservicing  Agreement,  pursuant to which
First  Tennessee  Mortgage  Services,   Inc.  engaged  the  Master  Servicer  to
subservice the Mortgage  Loans,  (ii) this Agreement and (iii) the customary and
usual standards of practice of prudent mortgage loan servicers; provided that if
there is a  conflict  between  the  terms  of the  Servicing  Agreement  and the
Servicing Rights Transfer and Subservicing  Agreement, on the one hand, and this
Agreement,  on the other hand,  the terms of this Agreement  shall  prevail.  In
connection  with such servicing and  administration,  the Master  Servicer shall
have full power and  authority,  acting alone  and/or  through  Subservicers  as
provided  in Section  3.2  hereof,  to do or cause to be done any and all things
that it may deem  necessary or desirable in connection  with such  servicing and
administration,  including but not limited to, the power and authority,  subject
to  the  terms   hereof  (i)  to  execute   and   deliver,   on  behalf  of  the
Certificateholders  and the  Trustee,  customary  consents  or waivers and other
instruments  and  documents,  (ii) to  consent  to  transfers  of any  Mortgaged
Property and  assumptions of the Mortgage Notes and related  Mortgages (but only
in the  manner  provided  in this  Agreement),  (iii) to collect  any  Insurance
Proceeds and other Liquidation Proceeds,  and (iv) to effectuate  foreclosure or
other  conversion  of the  ownership  of the  Mortgaged  Property  securing  any
Mortgage Loan;  provided that the Master Servicer shall not take any action that
is  inconsistent  with or  prejudices  the  interests  of the Trust  Fund or the
Certificateholders  in any  Mortgage  Loan or the  rights and  interests  of the
Depositor,  the Trustee and the  Certificateholders  under this  Agreement.  The
Master  Servicer shall  represent and protect the interests of the Trust Fund in
the same manner as it protects its own  interests  in mortgage  loans in its own
portfolio in any claim,  proceeding or litigation regarding a Mortgage Loan, and
shall not make or permit any  modification,  waiver or amendment of any Mortgage
Loan which would cause any REMIC created hereunder to fail to qualify as a REMIC
or result in the imposition of any tax under Section  860F(a) or Section 860G(d)
of the Code.  Without  limiting  the  generality  of the  foregoing,  the Master
Servicer,  in its own name or in the name of the Depositor  and the Trustee,  is


                                      -47-
<PAGE>

hereby  authorized  and  empowered by the  Depositor  and the Trustee,  when the
Master Servicer believes it appropriate in its reasonable  judgment,  to execute
and deliver, on behalf of the Trustee, the Depositor,  the Certificateholders or
any of them, any and all  instruments of  satisfaction  or  cancellation,  or of
partial or full release or discharge and all other comparable instruments,  with
respect to the Mortgage Loans, and with respect to the Mortgaged Properties held
for the benefit of the Certificateholders. The Master Servicer shall prepare and
deliver to the Depositor and/or the Trustee such documents  requiring  execution
and delivery by either or both of them as are necessary or appropriate to enable
the Master  Servicer to service and  administer the Mortgage Loans to the extent
that the Master  Servicer is not permitted to execute and deliver such documents
pursuant  to the  preceding  sentence.  Upon  receipt  of  such  documents,  the
Depositor  and/or the Trustee shall  execute such  documents and deliver them to
the Master Servicer.  The Master Servicer further is authorized and empowered by
the Trustee,  on behalf of the  Certificateholders  and the Trustee,  in its own
name  or in the  name  of the  Subservicer,  when  the  Master  Servicer  or the
Subservicer as the case may be,  believes it appropriate in its best judgment to
register any Mortgage Loan on the MERS(R) System,  or cause the removal from the
registration of any Mortgage Loan on the MERS(R) System, to execute and deliver,
on behalf of the Trustee and the  Certificateholders or any of them, any and all
instruments of assignment and other comparable  instruments with respect to such
assignment or re-recording of a Mortgage in the name of MERS,  solely as nominee
for the Trustee and its successors and assigns.

         In accordance with the standards of the preceding paragraph, the Master
Servicer  shall  advance  or cause to be  advanced  funds as  necessary  for the
purpose of  effecting  the  payment of taxes and  assessments  on the  Mortgaged
Properties,  which  advances  shall be  reimbursable  in the first instance from
related  collections from the Mortgagors pursuant to Section 3.6, and further as
provided in Section 3.8. 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 3.2 Subservicing; Enforcement of the Obligations of Servicers.

         (a)      The Master  Servicer may arrange for the  subservicing  of any
                  Mortgage  Loan by a  Subservicer  pursuant  to a  subservicing
                  agreement;   provided,   however,   that   such   subservicing
                  arrangement   and  the  terms  of  the  related   subservicing
                  agreement  must  provide for the  servicing  of such  Mortgage
                  Loans in a manner  consistent with the servicing  arrangements
                  contemplated hereunder. Unless the context otherwise requires,
                  references  in this  Agreement to actions taken or to be taken
                  by the Master Servicer in servicing the Mortgage Loans include
                  actions taken or to be taken by a Subservicer on behalf of the
                  Master  Servicer.   Notwithstanding   the  provisions  of  any
                  subservicing   agreement,   any  of  the  provisions  of  this
                  Agreement  relating to agreements or arrangements  between the
                  Master  Servicer  and a  Subservicer  or  reference to actions
                  taken through a Subservicer or otherwise,  the Master Servicer
                  shall  remain  obligated  and  liable  to the  Depositor,  the
                  Trustee  and  the  Certificateholders  for the  servicing  and
                  administration  of the Mortgage  Loans in accordance  with the
                  provisions  of  this  Agreement  without  diminution  of  such
                  obligation  or  liability  by  virtue  of  such   subservicing


                                      -48-
<PAGE>

                  agreements  or  arrangements  or by virtue of  indemnification
                  from the Subservicer and to the same extent and under the same
                  terms and  conditions  as if the  Master  Servicer  alone were
                  servicing and administering the Mortgage Loans. All actions of
                  each   Subservicer   performed   pursuant   to   the   related
                  subservicing  agreement  shall be performed as an agent of the
                  Master Servicer with the same force and effect as if performed
                  directly by the Master Servicer.

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

         SECTION 3.3 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 3.4 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 3.9 hereof or any acts or omissions of the  predecessor  Master Servicer
hereunder), (ii) obligated to make Advances if it is prohibited from doing so by
applicable law, (iii) obligated to effectuate  repurchases or  substitutions  of
Mortgage  Loans  hereunder  including,   but  not  limited  to,  repurchases  or
substitutions  of Mortgage  Loans  pursuant  to Section 2.2 or 2.3 hereof,  (iv)
responsible for expenses of the Master  Servicer  pursuant to Section 2.3 or (v)
deemed to have made any  representations  and warranties of the Master  Servicer
hereunder).  Any such assumption shall be subject to Section 7.2 hereof.  If the
Master Servicer shall for any reason no longer be the Master Servicer (including
by reason of any Event of Default),  the Trustee or its successor  shall succeed
to any rights and  obligations of the Master  Servicer  under each  subservicing
agreement.

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

         SECTION 3.5 Collection of Mortgage Loan Payments;  Certificate Account;
Distribution Account.

         (a)      The  Master   Servicer  shall  make   reasonable   efforts  in
                  accordance  with the customary and usual standards of practice
                  of prudent  mortgage  servicers to collect all payments called
                  for under the terms and  provisions  of the Mortgage  Loans to
                  the  extent  such  procedures  shall be  consistent  with this
                  Agreement and the terms and provisions of any related Required
                  Insurance  Policy.  Consistent with the foregoing,  the Master
                  Servicer  may in its  discretion  (i) waive  any late  payment
                  charge  or  any  prepayment  charge  or  penalty  interest  in
                  connection  with the  prepayment  of a Mortgage  Loan and (ii)
                  extend the due dates for payments due on a Mortgage Note for a
                  period not greater than 180 days; provided,  however, that the
                  Master  Servicer  cannot  extend  the  maturity  of  any  such
                  Mortgage  Loan past the date on which the final payment is due
                  on the latest  maturing  Mortgage Loan as of the Cut-off Date.
                  In the  event of any such  arrangement,  the  Master  Servicer
                  shall make Advances on the related Mortgage Loan in accordance
                  with the provisions of Section 4.1 during the scheduled period
                  in accordance with the amortization  schedule of such Mortgage
                  Loan   without   modification   thereof   by  reason  of  such
                  arrangements.  The Master  Servicer  shall not be  required to
                  institute or join in litigation  with respect to collection of
                  any  payment  (whether  under  a  Mortgage,  Mortgage  Note or
                  otherwise or against any public or governmental authority with
                  respect to a taking or condemnation) if it reasonably believes
                  that   enforcing  the  provision  of  the  Mortgage  or  other
                  instrument  pursuant  to which  such  payment is  required  is
                  prohibited by applicable law.

         (b)      The  Master   Servicer   shall   establish  and  maintain  the
                  Certificate  Account. The Certificate Account shall consist of
                  two  separate  subaccounts,  each of which  shall  relate to a
                  particular Mortgage Pool. The Master Servicer shall deposit or
                  cause to be deposited into the  appropriate  subaccount of the
                  Certificate  Account  no later  than two  Business  Days after
                  receipt, except as otherwise specifically provided herein, the
                  following payments and collections remitted by Subservicers or
                  received by it in respect of the Mortgage Loans  subsequent to
                  the  Cut-off  Date  (other  than in respect of  principal  and
                  interest  due on the  Mortgage  Loans on or before the Cut-off
                  Date)  and the  following  amounts  required  to be  deposited
                  hereunder:

                  (i)      all  payments on account of principal on the Mortgage
                           Loans  in  the  related   Mortgage  Pool,   including
                           Principal Prepayments;

                  (ii)     all  payments on account of interest on the  Mortgage
                           Loans  in  the  related  Mortgage  Pool,  net  of the
                           related  Master  Servicing  Fee  and  any  Prepayment
                           Interest Excess;


                                      -50-
<PAGE>

                  (iii)    all Insurance  Proceeds and  Liquidation  Proceeds in
                           respect of the related  Mortgage Loans in the related
                           Mortgage  Pool,  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  in respect  of the  related  Mortgage  Pool
                           pursuant  to Section  3.5(c) in  connection  with any
                           losses on Permitted Investments;

                  (v)      any amounts  required to be  deposited  by the Master
                           Servicer  in respect  of the  related  Mortgage  Pool
                           pursuant to Section 3.9(b) and 3.9(d);

                  (vi)     all Substitution Adjustment Amounts in respect of the
                           related Mortgage Pool;

                  (vii)    all Advances in respect of the related  Mortgage Pool
                           made by the Master Servicer  pursuant to Section 4.1;
                           and

                  (viii)   any other amounts required to be deposited  hereunder
                           in respect of the related Mortgage Pool.

                  In addition, with respect to any Mortgage Loan that is subject
         to a buydown  agreement,  on each Due Date for such  Mortgage  Loan, in
         addition to the monthly payment  remitted by the Mortgagor,  the Master
         Servicer  shall  cause  funds  to  be  deposited  into  the  applicable
         subaccount of the Certificate Account in an amount required to cause an
         amount of interest to be paid with respect to such  Mortgage Loan equal
         to the amount of interest  that has accrued on such  Mortgage Loan from
         the  preceding Due Date at the related  Adjusted  Mortgage Rate 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,  assumption fees
         or amounts  attributable to reimbursements  of Advances,  if collected,
         need not be  remitted  by the  Master  Servicer.  In the event that the
         Master Servicer shall remit any amount not required to be remitted,  it
         may at any time  withdraw  or direct the  institution  maintaining  the
         Certificate  Account  to  withdraw  such  amount  from the  Certificate
         Account,  any provision  herein to the contrary  notwithstanding.  Such
         withdrawal  or direction  may be  accomplished  by  delivering  written
         notice thereof to the Trustee or such other institution maintaining the
         Certificate  Account which describes the amounts  deposited in error in
         the Certificate  Account.  The Master Servicer shall maintain  adequate
         records with respect to all withdrawals  made pursuant to this Section.
         All funds deposited in the  Certificate  Account shall be held in trust
         for the  Certificateholders  until withdrawn in accordance with Section
         3.8.

         (c)      The Trustee shall  establish  and  maintain,  on behalf of the
                  Certificateholders, the Distribution Account. The Distribution
                  Account  shall  consist of two separate  subaccounts,  each of
                  which shall relate to a particular  Mortgage Pool. The Trustee
                  shall,  promptly  upon  receipt,  deposit in the  Distribution
                  Account and retain therein the following:


                                      -51-
<PAGE>

                  (i)      the aggregate  amount remitted by the Master Servicer
                           to the Trustee in respect of a Mortgage Pool pursuant
                           to Section 3.8(a)(ix);

                  (ii)     any amount deposited by the Master Servicer  pursuant
                           to this Section 3.5(c) 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 applicable subaccount of 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   related
         Certificateholders until disbursed in accordance with this Agreement or
         withdrawn in accordance with Section 3.8. In no event shall the Trustee
         incur liability for withdrawals  from the  Distribution  Account at the
         direction of the Master Servicer.

                  (iv)     The institutions at which the Certificate Account and
                           the Distribution  Account are maintained shall invest
                           funds as directed by the Master Servicer in Permitted
                           Investments  which in both  cases  shall  mature  not
                           later  than  (i)  in  the  case  of  the  Certificate
                           Account,  the second  Business Day next preceding the
                           related  Distribution  Account  Deposit  Date (except
                           that if such Permitted Investment is an obligation of
                           the  institution  that maintains  such account,  then
                           such Permitted Investment shall mature not later than
                           the Business  Day next  preceding  such  Distribution
                           Account  Deposit  Date)  and  (ii) in the case of the
                           Distribution Account, the Business Day next preceding
                           the Distribution  Date (except that if such Permitted
                           Investment is an obligation of the  institution  that
                           maintains  such fund or account,  then such Permitted
                           Investment   shall   mature   not  later   than  such
                           Distribution  Date) and,  in each case,  shall not be
                           sold or  disposed  of prior to its  maturity.  If the
                           Master  Servicer  does not provide such prior written
                           investment direction, the funds in such accounts will
                           be held  uninvested.  All such Permitted  Investments
                           shall  be made in the  name of the  Trustee,  for the
                           benefit  of the  Certificateholders.  All  income and
                           gain  net  of  any  losses  realized  from  any  such
                           investment  of funds on  deposit  in the  Certificate
                           Account  shall  be for  the  benefit  of  the  Master
                           Servicer as servicing compensation and all income and
                           gain  net  of  any  losses  realized  from  any  such
                           investment  of funds on deposit  in the  Distribution
                           Account shall be for the benefit of the Trustee.  The
                           amount  of any  Realized  Losses  in the  Certificate
                           Account  in  respect  of any such  investments  shall
                           promptly be deposited  by the Master  Servicer in the


                                      -52-
<PAGE>

                           Certificate  Account  and the amount of any  Realized
                           Losses in the Distribution  Account in respect of any
                           such  investments  shall promptly be deposited by the
                           Trustee   into   the   Distribution    Account.   All
                           reinvestment  income  earned on amounts on deposit in
                           the Distribution  Account shall be for the benefit of
                           the Trustee.  The Trustee in its  fiduciary  capacity
                           shall  not be  liable  for  the  amount  of any  loss
                           incurred  in  respect  of any  investment  or lack of
                           investment of funds held in the  Certificate  Account
                           and made in accordance with this Section 3.5.

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

         SECTION 3.6 Collection of Taxes,  Assessments and Similar Items; Escrow
Accounts.

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

         (b)      Withdrawals of amounts so collected  from the Escrow  Accounts
                  may  be  made  only  to  effect   timely   payment  of  taxes,
                  assessments,  hazard  insurance  premiums,  condominium or PUD
                  association dues, or comparable items, to reimburse the Master
                  Servicer  out of related  collections  for any  payments  made
                  pursuant to  Sections  3.1 hereof  (with  respect to taxes and
                  assessments  and  insurance  premiums)  and 3.9  hereof  (with
                  respect to hazard insurance),  to refund to any Mortgagors any
                  sums determined to be overages,  to pay interest,  if required
                  by law or the terms of the related  Mortgage or Mortgage Note,
                  to  Mortgagors  on balances in the Escrow  Account or to clear
                  and terminate the Escrow  Account at the  termination  of this
                  Agreement in  accordance  with Section 9.1 hereof.  The Escrow
                  Accounts shall not be a part of the Trust Fund.

         (c)      The Master Servicer shall advance any payments  referred to in
                  Section  3.6(a) that are not timely paid by the  Mortgagors on
                  the date when the tax,  premium  or other  cost for which such
                  payment is intended is due, but the Master  Servicer  shall be
                  required so to advance only to the extent that such  advances,
                  in the good faith  judgment  of the Master  Servicer,  will be
                  recoverable by the Master Servicer out of Insurance  Proceeds,
                  Liquidation Proceeds or otherwise.

                  (v)      to reimburse the Master Servicer for (a) unreimbursed

                  The  Master   Servicer   shall  keep  and  maintain   separate
         accounting, on a Mortgage Loan-by-Mortgage Loan basis and on a Mortgage

         (i), (ii),  (iv), (v) and (vi). Prior to making any withdrawal from the
         Certificate  Account  pursuant to subclause  (iii), the Master Servicer
         shall  deliver to the Trustee an Officer's  Certificate  of a Servicing
         Officer indicating the amount of any previous Advance determined by the
         Master  Servicer to be a  Nonrecoverable  Advance and  identifying  the

         (b)      The  Trustee  shall   withdraw   funds  from  the   applicable
                  subaccount of the  Distribution  Account for  distributions to
                  the related 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 (and with  respect to clauses (i) and (ii) below,
                  shall),  prior to making the distribution  pursuant to Section
                  4.2 from time to time make  withdrawals  from the Distribution

                  (ii)     to pay to itself  earnings  on or  investment  income
                           with respect to funds in the Distribution Account;

<PAGE>

                  (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 9.1
                           hereof.

         SECTION 3.9  Maintenance  of Hazard  Insurance;  Maintenance of Primary
Insurance Policies.

         (a)      The Master  Servicer  shall cause to be  maintained,  for each
                  Mortgage Loan,  hazard insurance with extended  coverage in an
                  amount that is at least equal to the lesser of (i) the maximum
                  insurable  value of the  improvements  securing  such Mortgage
                  Loan or (ii)  the  greater  of (y) the  outstanding  principal
                  balance of the  Mortgage  Loan and (z) an amount such that the
                  proceeds of such  policy  shall be  sufficient  to prevent the
                  Mortgagor  and/or the  mortgagee  from  becoming a co-insurer.
                  Each such policy of standard  hazard  insurance shall contain,
                  or have an accompanying  endorsement that contains, a standard
                  mortgagee clause. Any amounts collected by the Master Servicer
                  under any such policies  (other than the amounts to be applied
                  to the restoration or repair of the related Mortgaged Property
                  or amounts  released to the Mortgagor in  accordance  with the
                  Master  Servicer's  normal  servicing   procedures)  shall  be
                  deposited  in the  applicable  subaccount  of the  Certificate
                  Account.   Any  cost  incurred  by  the  Master   Servicer  in
                  maintaining  any such insurance  shall not, for the purpose of
                  calculating monthly distributions to the Certificateholders or
                  remittances to the Trustee for their benefit,  be added to the
                  principal balance of the Mortgage Loan,  notwithstanding  that
                  the terms of the Mortgage Loan so permit.  Such costs shall be
                  recoverable by the Master Servicer out of late payments by the
                  related Mortgagor or out of Liquidation Proceeds to the extent
                  permitted by Section 3.8 hereof.  It is understood  and agreed
                  that no  earthquake  or other  additional  insurance  is to be
                  required of any Mortgagor or  maintained on property  acquired
                  in  respect  of  a  Mortgage   other  than  pursuant  to  such
                  applicable  laws  and  regulations  as shall at any time be in
                  force and as shall require such additional  insurance.  If the
                  Mortgaged  Property is located at the time of  origination  of
                  the  Mortgage  Loan in a federally  designated  special  flood
                  hazard  area and such area is  participating  in the  national
                  flood insurance program, the Master Servicer shall cause flood
                  insurance to be maintained with respect to such Mortgage Loan.
                  Such flood  insurance shall be in an amount equal to the least
                  of (i) the original  principal balance of the related Mortgage
                  Loan, (ii) the replacement value of the improvements which are
                  part of such Mortgaged Property,  and (iii) the maximum amount
                  of such insurance available for the related Mortgaged Property
                  under the national flood insurance program.

         (b)      In the  event  that  the  Master  Servicer  shall  obtain  and
                  maintain a blanket  policy  insuring  against hazard losses on
                  all of the Mortgage Loans, it shall  conclusively be deemed to
                  have  satisfied  its  obligations  as set  forth in the  first
                  sentence of this Section,  it being understood and agreed that
                  such  policy  may  contain  a   deductible   clause  on  terms
                  substantially  equivalent to those commercially  available and


                                      -56-
<PAGE>

                  maintained by comparable servicers.  If such policy contains a
                  deductible  clause,  the Master  Servicer  shall, in the event
                  that  there  shall not have  been  maintained  on the  related
                  Mortgaged  Property a policy complying with the first sentence
                  of this  Section,  and there shall have been a loss that would
                  have been  covered by such policy,  deposit in the  applicable
                  subaccount of the Certificate Account the amount not otherwise
                  payable under the blanket  policy  because of such  deductible
                  clause.  In connection  with its activities as Master Servicer
                  of the Mortgage Loans,  the Master Servicer agrees to present,
                  on behalf of itself,  the  Depositor,  and the Trustee for the
                  benefit  of the  Certificateholders,  claims  under  any  such
                  blanket policy.

         (c)      The  Master  Servicer  shall not take any action  which  would
                  result in non-coverage  under any applicable Primary Insurance
                  Policy of any loss  which,  but for the  actions of the Master
                  Servicer,  would  have been  covered  thereunder.  The  Master
                  Servicer  shall not cancel or refuse to renew any such Primary
                  Insurance  Policy that is in effect at the date of the initial
                  issuance  of the  Certificates  and is  required to be kept in
                  force  hereunder  unless  the  replacement  Primary  Insurance
                  Policy for such canceled or  non-renewed  policy is maintained
                  with a Qualified Insurer.

         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 effect the timely payment of the premiums
on each Primary Insurance Policy, and such costs not otherwise recoverable shall
be recoverable by the Master Servicer from the related liquidation proceeds.

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

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

         (a)      Except  as  otherwise  provided  in  this  Section,  when  any
                  property  subject  to a  Mortgage  has  been  conveyed  by the
                  Mortgagor, the Master Servicer shall to the extent that it has
                  knowledge of such conveyance,  enforce any due-on-sale  clause
                  contained  in any  Mortgage  Note or  Mortgage,  to the extent
                  permitted under applicable law and  governmental  regulations,
                  but  only  to  the  extent  that  such  enforcement  will  not
                  adversely  affect or  jeopardize  coverage  under any Required
                  Insurance Policy.  Notwithstanding  the foregoing,  the Master
                  Servicer is not required to exercise  such rights with respect


                                      -57-
<PAGE>

                  to a Mortgage Loan if the Person to whom the related Mortgaged
                  Property  has been  conveyed  or is  proposed  to be  conveyed
                  satisfies the terms and  conditions  contained in the Mortgage
                  Note and  Mortgage  related  thereto  and the  consent  of the
                  mortgagee   under  such  Mortgage  Note  or  Mortgage  is  not
                  otherwise so required  under such Mortgage Note or Mortgage as
                  a  condition  to such  transfer.  In the event that the Master
                  Servicer  is  prohibited  by  law  from   enforcing  any  such
                  due-on-sale   clause,   or  if  coverage  under  any  Required
                  Insurance   Policy   would  be  adversely   affected,   or  if
                  nonenforcement is otherwise  permitted  hereunder,  the Master
                  Servicer is authorized, subject to Section 3.10(b), to take or
                  enter into an assumption  and  modification  agreement from or
                  with the person to whom such  property has been or is about to
                  be  conveyed,  pursuant  to which such person  becomes  liable
                  under the Mortgage Note and,  unless  prohibited by applicable
                  state law, the Mortgagor remains liable thereon, provided that
                  the Mortgage Loan shall  continue to be covered (if so covered
                  before the  Master  Servicer  enters  such  agreement)  by the
                  applicable Required Insurance  Policies.  The Master Servicer,
                  subject to Section 3.10(b),  is also authorized with the prior
                  approval of the insurers under any Required Insurance Policies
                  to enter into a substitution of liability  agreement with such
                  Person,  pursuant to which the original  Mortgagor is released
                  from liability and such Person is substituted as Mortgagor and
                  becomes  liable under the Mortgage Note.  Notwithstanding  the
                  foregoing,  the Master  Servicer  shall not be deemed to be in
                  default  under  this  Section  by  reason of any  transfer  or
                  assumption which the Master Servicer reasonably believes it is
                  restricted by law from preventing, for any reason whatsoever.

         (b)      Subject  to  the  Master   Servicer's   duty  to  enforce  any
                  due-on-sale  clause to the extent set forth in Section 3.10(a)
                  hereof,  in any case in which a  Mortgaged  Property  has been
                  conveyed  to a Person by a  Mortgagor,  and such  Person is to
                  enter into an assumption  agreement or modification  agreement
                  or  supplement  to the Mortgage Note or Mortgage that requires
                  the  signature of the Trustee,  or if an instrument of release
                  signed by the Trustee is required releasing the Mortgagor from
                  liability  on the Mortgage  Loan,  the Master  Servicer  shall
                  prepare and deliver or cause to be prepared  and  delivered to
                  the Trustee for signature and shall  direct,  in writing,  the
                  Trustee to execute the assumption agreement with the Person to
                  whom  the  Mortgaged  Property  is to  be  conveyed  and  such
                  modification  agreement or  supplement to the Mortgage Note or
                  Mortgage or other  instruments  as are reasonable or necessary
                  to carry out the terms of the  Mortgage  Note or  Mortgage  or
                  otherwise  to  comply  with  any  applicable   laws  regarding
                  assumptions or the transfer of the Mortgaged  Property to such
                  Person.  In connection with any such  assumption,  no material
                  term of the Mortgage  Note may be changed.  In  addition,  the
                  substitute  Mortgagor  and  the  Mortgaged  Property  must  be
                  acceptable  to the  Master  Servicer  in  accordance  with its
                  underwriting  standards as then in effect.  Together with each
                  such substitution, assumption or other agreement or instrument
                  delivered  to the  Trustee  for  execution  by it,  the Master
                  Servicer  shall deliver an Officer's  Certificate  signed by a
                  Servicing  Officer  stating  that  the  requirements  of  this
                  subsection have been met in connection  therewith.  The Master
                  Servicer  shall notify the Trustee that any such  substitution
                  or assumption  agreement  has been  completed by forwarding to


                                      -58-
<PAGE>

                  the Trustee the original of such  substitution  or  assumption
                  agreement, which in the case of the original shall be added to
                  the related  Mortgage  File and shall,  for all  purposes,  be
                  considered a part of such  Mortgage File to the same extent as
                  all  other  documents  and  instruments  constituting  a  part
                  thereof. Any fee collected by the Master Servicer for entering
                  into an assumption or substitution of liability agreement will
                  be retained by the Master  Servicer  as  additional  servicing
                  compensation.

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

         The Master  Servicer shall use reasonable  efforts to foreclose upon or
otherwise  comparably  convert the ownership of properties  securing such of the
Mortgage  Loans  as come  into  and  continue  in  default  and as to  which  no
satisfactory  arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion,  the Master Servicer shall
follow such practices and procedures as it shall deem necessary or advisable and
as shall be normal and usual in its general  mortgage  servicing  activities and
meet the  requirements  of the  insurer  under any  Required  Insurance  Policy;
provided,  however, that the Master Servicer shall not be required to expend its
own funds in connection  with any  foreclosure or towards the restoration of any
property unless it shall determine (i) that such restoration  and/or foreclosure
will  increase  the  proceeds  of   liquidation   of  the  Mortgage  Loan  after
reimbursement  to itself of such  expenses and (ii) that such  expenses  will be
recoverable to it through Liquidation  Proceeds  (respecting which it shall have
priority for purposes of withdrawals from the Certificate  Account).  The Master
Servicer shall be responsible for all other costs and expenses incurred by it in
any  such  proceedings;   provided,  however,  that  it  shall  be  entitled  to
reimbursement  thereof from the liquidation proceeds with respect to the related
Mortgaged Property,  as provided in the definition of Liquidation  Proceeds.  If
the Master  Servicer has knowledge  that a Mortgaged  Property  which the Master
Servicer  is  contemplating  acquiring  in  foreclosure  or by  deed  in lieu of
foreclosure  is  located  within  a 1 mile  radius  of any  site  listed  in the
Expenditure Plan for the Hazardous  Substance Clean Up Bond Act of 1984 or other
site with  environmental  or hazardous waste risks known to the Master Servicer,
the Master Servicer will,  prior to acquiring the Mortgaged  Property,  consider
such risks and only take action in accordance with its established environmental
review procedures.

         With respect to any REO Property, the deed or certificate of sale shall
be  taken   in  the  name  of  the   Trust   Fund   for  the   benefit   of  the
Certificateholders,  or its nominee,  on behalf of the  Certificateholders.  The
Master Servicer shall ensure that the title to such REO Property  references the
Pooling  and  Servicing  Agreement  and the Trust  Fund's  capacity  thereunder.
Pursuant to its efforts to sell such REO  Property,  the Master  Servicer  shall
either itself or through an agent  selected by the Master  Servicer  protect and
conserve such REO Property in the same manner and to such extent as is customary
in the locality  where such REO Property is located.  The Master  Servicer shall
perform the tax reporting and withholding required by Sections 1445 and 6050J of
the Code with  respect  to  foreclosures  and  abandonments,  the tax  reporting
required  by Section  6050H of the Code with  respect to the receipt of mortgage
interest from individuals and any tax reporting required by Section 6050P of the
Code with  respect to the  cancellation  of  indebtedness  by certain  financial
entities,  by preparing such tax and information returns as may be required,  in
the form required, and delivering the same to the Trustee for filing.


                                      -59-
<PAGE>

         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 the close of the third  taxable  year  after  the  taxable  year of 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"  of any REMIC  hereunder  as
defined in Section 860F of the Code or cause any REMIC created hereunder to fail
to  qualify as a REMIC at any time that any  Certificates  are  outstanding,  in
which case the Trust Fund may continue to hold such Mortgaged  Property (subject
to any  conditions  contained in such Opinion of Counsel).  Notwithstanding  any
other provision of this Agreement,  no Mortgaged  Property acquired by the Trust
Fund shall be rented (or allowed to continue to be rented) or otherwise used for
the  production  of income by or on behalf of the Trust Fund in such a manner or
pursuant  to any terms that would (i) cause such  Mortgaged  Property to fail to
qualify as "foreclosure  property"  within the meaning of Section  860G(a)(8) of
the Code or (ii) subject any REMIC  hereunder to the  imposition of any federal,
state or local income taxes on the income  earned from such  Mortgaged  Property
under Section  860G(c) of the Code or otherwise,  unless the Master Servicer has
agreed to  indemnify  and hold  harmless  the Trust  Fund  with  respect  to the
imposition of any such taxes.

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

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

         The proceeds from any  liquidation  of a Mortgage  Loan, as well as any
income from an REO Property, will be applied in the following order of priority:
first, to reimburse the Master Servicer for any related  unreimbursed  Servicing
Advances and Master Servicing Fees; second, to reimburse the Master Servicer for
any unreimbursed Advances;  third, to reimburse the applicable subaccount of the


                                      -60-
<PAGE>

Certificate  Account for any Nonrecoverable  Advances (or portions thereof) that
were previously withdrawn by the Master Servicer pursuant to Section 3.8(a)(iii)
that related to such Mortgage Loan;  fourth,  to accrued and unpaid interest (to
the extent no Advance has been made for such amount or any such Advance has been
reimbursed)  on the Mortgage Loan or related REO  Property,  at the Adjusted Net
Mortgage  Rate to the Due Date  occurring in the month in which such amounts are
required  to be  distributed;  and fifth,  as a  recovery  of  principal  of the
Mortgage Loan.  Excess  Proceeds,  if any, from the  liquidation of a Liquidated
Mortgage Loan will be retained by the Master  Servicer as  additional  servicing
compensation pursuant to Section 3.14.

         The Master  Servicer,  with the consent of the Trustee,  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  applicable  subaccount  of the  Certificate  Account and the Trustee,  upon
receipt  of a  certificate  from the  Master  Servicer  in the form of Exhibit M
hereto,  shall release or cause to be released to the purchaser of such Mortgage
Loan the related Mortgage File and shall execute and deliver such instruments of
transfer or assignment  prepared by the purchaser of such Mortgage Loan, in each
case without  recourse,  as shall be necessary to vest in the  purchaser of such
Mortgage Loan any Mortgage Loan  released  pursuant  hereto and the purchaser of
such Mortgage Loan shall succeed to all the Trustee's right,  title and interest
in and to such  Mortgage Loan and all security and  documents  related  thereto.
Such  assignment  shall be an  assignment  outright  and not for  security.  The
purchaser of such Mortgage Loan shall  thereupon own such Mortgage Loan, and all
security and  documents,  free of any further  obligation  to the Trustee or the
Certificateholders with respect thereto.

         SECTION 3.12 Trustee to Cooperate; Release of Mortgage Files.

         Upon the payment in full of any  Mortgage  Loan,  or the receipt by the
Master  Servicer of a  notification  that  payment in full will be escrowed in a
manner customary for such purposes,  the Master Servicer will immediately notify
the Trustee by  delivering,  or causing to be  delivered a "Request for Release"
substantially  in the form of  Exhibit  M. Upon  receipt  of such  request,  the
Trustee  shall or shall  cause the  Custodian  to  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 L signed by a Servicing  Officer,  release  the  Mortgage
File to the Master Servicer. Subject to the further limitations set forth below,
the Master Servicer shall cause the Mortgage File or documents so released to be
returned to the Trustee or its  Custodian  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 applicable  subaccount of the Certificate
Account,  in which  case the Master  Servicer  shall  deliver  to the  Trustee a
Request for Release in the form of Exhibit M, signed by a Servicing Officer.


                                      -61-
<PAGE>

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

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

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

         SECTION 3.14 Master Servicing Compensation.

         As compensation for its activities as Master Servicer  hereunder and as
a  subservicer  pursuant  to the  Servicing  Rights  Transfer  and  Subservicing
Agreement,  the Master Servicer shall be entitled to retain or withdraw from the
Certificate  Account  an  amount  equal  to the  Master  Servicing  Fee for each
Mortgage Loan,  provided that the aggregate Master Servicing Fee with respect to
any  Distribution  Date shall be reduced  (i) by the amount of any  Compensating
Interest paid by the Master Servicer with respect to such Distribution Date, and
(ii) with respect to the first  Distribution Date, an amount equal to any amount
to be  deposited  into the  Distribution  Account by the  Depositor  pursuant to
Section 2.1(a) and not so deposited.


                                      -62-
<PAGE>

         Additional  servicing  compensation in the form of (i) Excess Proceeds,
Prepayment  Interest  Excess and all income and gain net of any losses  realized
from Permitted  Investments and (ii) prepayment  penalties,  assumption fees and
late payment charges in each case under the  circumstances and in the manner set
forth in the  applicable  Mortgage  Note or  Mortgage  shall be  retained by the
Master  Servicer to the extent not required to be  deposited in the  Certificate
Account pursuant to Section 3.5 hereof. The Master Servicer shall be required to
pay  all  expenses  incurred  by it in  connection  with  its  master  servicing
activities hereunder (including payment of any premiums for hazard insurance and
any Primary  Insurance  Policy and  maintenance  of the other forms of insurance
coverage  required by this Agreement) and shall not be entitled to reimbursement
therefor except as specifically provided in this Agreement.

         SECTION 3.15 Access to Certain Documentation.

         The  Master  Servicer  shall  provide  to the OTS and the  FDIC  and to
comparable  regulatory  authorities   supervising  Holders  of  Certificates  or
Certificate Owners and the examiners and supervisory agents of the OTS, the FDIC
and such other authorities,  access to the documentation  regarding the Mortgage
Loans required by applicable  regulations  of the OTS and the FDIC.  Such access
shall be afforded  without  charge,  but only upon  reasonable and prior written
request and during normal business hours at the offices designated by the Master
Servicer.  Nothing in this  Section  shall  limit the  obligation  of the Master
Servicer to observe any  applicable  law  prohibiting  disclosure of information
regarding  the  Mortgagors  and the  failure of the Master  Servicer  to provide
access as  provided  in this  Section as a result of such  obligation  shall not
constitute a breach of this Section.

         SECTION 3.16 Annual Statement as to Compliance.

         The Master  Servicer  shall deliver to the Depositor and the Trustee on
or  before  120  days  after  the  end of the  Master  Servicer's  fiscal  year,
commencing with its 2005 fiscal year, an Officer's  Certificate  stating,  as to
the signer  thereof,  that (i) a review of the activities of the Master Servicer
during the preceding calendar year and of the performance of the Master Servicer
under this Agreement has been made under such officer's  supervision and (ii) to
the best of such officer's knowledge,  based on such review, the Master Servicer
has fulfilled all its obligations under this Agreement throughout such year, or,
if  there  has  been a  default  in the  fulfillment  of  any  such  obligation,
specifying  each such  default  known to such  officer and the nature and status
thereof.  The Trustee shall forward a copy of each such statement to each Rating
Agency.

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

         On or before  120 days after the end of the  Master  Servicer's  fiscal
year,  commencing  with its 2005 fiscal year, the Master Servicer at its expense
shall cause a nationally or regionally  recognized  firm of  independent  public
accountants  (who may also render  other  services to the Master  Servicer,  the
Seller or any affiliate  thereof) which is a member of the American Institute of
Certified  Public  Accountants  to furnish a  statement  to the  Trustee and the
Depositor  to the effect  that-such  firm has  examined  certain  documents  and
records  relating to the servicing of the Mortgage Loans under this Agreement or
of mortgage loans under pooling and servicing agreements  substantially  similar


                                      -63-
<PAGE>

to this Agreement  (such statement to have attached  thereto a schedule  setting
forth the pooling and  servicing  agreements  covered  thereby) and that, on the
basis  of such  examination,  conducted  substantially  in  compliance  with the
Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for
Mortgages  serviced for FNMA and FHLMC,  such  servicing  has been  conducted in
compliance  with  such  pooling  and  servicing   agreements   except  for  such
significant  exceptions  or errors in records that, in the opinion of such firm,
the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program
for Mortgages  serviced for FNMA and FHLMC  requires it to report.  In rendering
such statement,  such firm may rely, as to matters  relating to direct servicing
of mortgage loans by Subservicers,  upon comparable  statements for examinations
conducted  substantially  in  compliance  with the  Uniform  Single  Attestation
Program for Mortgage  Bankers or the Audit  Program for  Mortgages  serviced for
FNMA and FHLMC  (rendered  within  one year of such  statement)  of  independent
public  accountants  with  respect to the  related  Subservicer.  Copies of such

         SECTION 3.18 Errors and Omissions Insurance; Fidelity Bonds.

         The  Master  Servicer  shall for so long as it acts as master  servicer
under this  Agreement,  obtain and maintain in force (a) a policy or policies of
insurance covering errors and omissions in the performance of its obligations as
Master  Servicer  hereunder  and (b) a fidelity bond in respect of its officers,
employees  and agents.  Each such policy or policies  and bond shall,  together,
comply  with the  requirements  from time to time of FNMA or FHLMC  for  persons
performing servicing for mortgage loans purchased by FNMA or FHLMC. In the event
that any such policy or bond ceases to be in effect,  the Master  Servicer shall

Mortgage Note and applicable  regulations  regarding  interest rate adjustments.
The Master Servicer also shall provide timely notification to the Trustee of all

discovery  by the Master  Servicer or the Trustee  that the Master  Servicer has
failed  to adjust  or has  incorrectly  adjusted  a  Mortgage  Rate or a monthly
payment  pursuant to the terms of the related  Mortgage Note and  Mortgage,  the
Master Servicer shall  immediately  deposit in the Certificate  Account from its
own funds the amount of any interest loss caused thereby  without  reimbursement
therefor;  provided,  however,  the Master  Servicer shall be held harmless with
respect to any  interest  rate  adjustments  made by any  servicer  prior to the
Master Servicer.

                  (i)      to the  Class  I-A-R  Certificates,  until  the Class
                           Certificate Balance thereof has been reduced to zero;

         (c)      Amounts allocated to the Group II Senior Certificates pursuant
                  to Section  4.2(a)(iii) above will be distributed to the Class
                  II-A-1   Certificates  until  the  Class  Certificate  Balance
                  thereof has been reduced to zero.

         (d)      On each Distribution Date, the Trustee shall distribute to the

                  Date,  regardless of the  priorities  and amounts set forth in
                  Section 4.2.

         (f)      If on any Distribution Date (i) the Class Certificate  Balance
                  of any  Class of  Subordinated  Certificates  (other  than the
                  Class of Subordinated  Certificates  with the highest priority
                  of  distribution)  for  which  the  related  Class  Prepayment
                  Distribution  Trigger was satisfied on such  Distribution Date
                  is  reduced  to zero and (ii)  amounts  distributable  to such
                  Class or  Classes of  Subordinated  Certificates  pursuant  to
                  clauses  (2),  (3)  and  (5)  of the  applicable  Subordinated

                  such date  pursuant to clauses  (iv)  through  (ix) of Section
                  4.2(a) have been distributed,  such amounts,  to the extent of
                  such Class' remaining Allocable Share, shall be distributed on
                  such   Distribution   Date  to  the   remaining   Classes   of
                  Subordinated  Certificates on a pro rata basis, subject to the
                  priority of payments described in Section 4.2(a).

         (g)      In the event that in any  calendar  month the Master  Servicer
                  recovers an amount (an "Unanticipated Recovery") in respect of
                  principal  of  a  Mortgage  Loan  which  had  previously  been
                  allocated  as a  Realized  Loss to any  Class of  Certificates

                  pursuant to Section 4.4, on the Distribution  Date in the next
                  succeeding  calendar  month,  the Trustee  shall  withdraw the
                  Unanticipated  Recovery  from  the  Distribution  Account  and
                  sequentially increase, in order of payment priority, the Class
                  Certificate  Balance  of each Class of  Certificates  to which
                  such Realized Losses were  previously  allocated by the amount
                  of such Unanticipated  Recovery,  but not to exceed the amount
                  of Realized Losses previously allocated to such Class pursuant
                  to  Section  4.4,  and  shall  distribute  the  amount of such
                  Unanticipated  Recovery to each such Class of  Certificates in
                  the order of payment  priority  described in Section 4.2(a) of
                  this Agreement. Holders of any Class of Certificates for which
                  the Class Certificate Balance has been increased by the amount
                  of any  Unanticipated  Recovery  will not be  entitled  to any
                  payment  in respect of  Accrued  Certificate  Interest  on the
                  amount of any such  increase for any Interest  Accrual  Period
                  preceding the Distribution Date on which such increase occurs.
                  When the Class Certificate  Balance of a Class of Certificates
                  has been reduced to zero,  the Holders of such Class shall not
                  be entitled  to any share of an  Unanticipated  Recovery,  and
                  such  Unanticipated  Recovery  shall be  allocated  among  all
                  outstanding  Classes  of  Certificates   entitled  thereto  in
                  accordance  with  the  preceding  sentence,   subject  to  the
                  remainder  of this  subsection  (g). In the event that (i) any
                  Unanticipated  Recovery  remains  undistributed  in accordance
                  with  the  preceding   sentence  or  (ii)  the  amount  of  an
                  Unanticipated Recovery exceeds the amount of the Realized Loss
                  previously  allocated to any outstanding  Classes with respect
                  to the related  Mortgage Loan, on the applicable  Distribution
                  Date  the  Trustee   shall   distribute   such   Unanticipated
                  Recoveries  in  accordance  with the  priorities  set forth in
                  Section 4.2(a).

                           For purposes of the preceding paragraph, the share of
                  an   Unanticipated   Recovery   allocable   to  any  Class  of
                  Certificates with respect to a Mortgage Loan shall be based on
                  its pro rata  share (in  proportion  to the Class  Certificate
                  Balances  thereof with respect to such  Distribution  Date) of
                  the principal  portion of any such  Realized  Loss  previously
                  allocated with respect to such Mortgage Loan (or Loans).

         (h)      On any  Distribution  Date  on  which  any  Certificate  Group
                  constitutes   an   Undercollateralized   Group,   all  amounts
                  otherwise  distributable  as  principal  on  the  Subordinated
                  Certificates,  in reverse order of priority (or, following the
                  Cross-over   Date,   such  other  amounts   described  in  the
                  immediately  following  sentence),   will  be  distributed  as
                  principal    to    the    Senior    Certificates    of    such
                  Undercollateralized  Group in accordance  with the  priorities
                  set forth in  Sections  4.2(b)  and (c) until the total  Class
                  Certificate  Balance of such Senior Certificates (after giving
                  effect to distributions to be made on that Distribution  Date)
                  equals the Stated  Principal  Balance of the related  Mortgage
                  Pool   (such    distribution,    an    "Undercollateralization
                  Distribution").  If the Senior  Certificates  of a Certificate
                  Group   constitute   an   Undercollateralized   Group  on  any
                  Distribution    Date    following   the    Cross-over    Date,
                  Undercollateralization  Distributions  will be made  from  the
                  excess  of the  Available  Funds  for the  Mortgage  Pool  not
                  related to an  Undercollateralized  Group  remaining after all
                  required  amounts  for  that   Distribution   Date  have  been
                  distributed   to  the  Senior   Certificates   of  such  other

                  Certificate  Group.  In  addition,  the  amount of any  unpaid
                  Accrued    Certificate    Interest   with   respect   to   any
                  Undercollateralized  Group on any Distribution Date (including
                  any Accrued Certificate  Interest for the related Distribution
                  Date) will be distributed to the Senior  Certificates  of such
                  Undercollateralized   Group   prior  to  the  payment  of  any
                  Undercollateralization  Distributions  from amounts  otherwise
                  distributable as principal on the  Subordinated  Certificates,
                  in reverse  order of priority (or,  following  the  Cross-over
                  Date,  as  provided  in the  preceding  sentence).  Except  as
                  provided  otherwise in this Section 4.2(h), no distribution of
                  principal   will  be  made  to  any   Class  of   Subordinated
                  Certificates until an  Undercollateralized  Group is no longer
                  undercollateralized.  If  more  than  one  Undercollateralized
                  Group   on  any   Distribution   Date   is   entitled   to  an
                  Undercollateralization            Distribution,           such
                  Undercollateralization  Distribution  shall be allocated among
                  the Undercollateralized  Groups, pro rata, on the basis of the
                  amount by which the aggregate Class Certificate Balance of the
                  related  Senior  Certificates  is greater  than the  aggregate
                  Stated Principal  Balance of the Mortgage Loans in the related
                  Undercollateralized Groups.

                  In  addition,  if on any  Distribution  Date the  total  Class
                  Certificate   Balance   of  the  Senior   Certificates   of  a
                  Certificate  Group (after giving effect to distributions to be
                  made on that Distribution  Date) has been reduced to zero, all
                  amounts otherwise distributable as prepayments of principal to
                  the Subordinated  Certificates,  in reverse order of priority,
                  will  instead  be  distributed  as  principal  to  the  Senior
                  Certificates of the other  Certificate  Group pro rata, on the
                  basis  of  the  aggregate  Class  Certificate  Balance  of the
                  related   Senior   Certificates,   unless  (a)  the  Aggregate
                  Subordinated Percentage for such Distribution Date is at least
                  two  times the  Aggregate  Subordinated  Percentage  as of the
                  Closing Date, (b) the aggregate  Stated  Principal  Balance of
                  all the Mortgage  Loans in the Mortgage  Pools  delinquent  60
                  days or more (including for this purpose any Mortgage Loans in
                  foreclosure or subject to bankruptcy  proceedings and Mortgage
                  Loans with respect to which the related Mortgaged Property has
                  been acquired by the Trust Fund),  averaged over the preceding
                  six  month  period,  as  a  percentage  of  the  then  current
                  aggregate  Class  Certificate   Balance  of  the  Subordinated
                  Certificates,  is  less  than  50%,  and  (c)  the  cumulative
                  Realized  Losses in both Mortgage  Pools do not exceed (i) 20%
                  of  the  Original  Subordinated   Principal  Balance  if  such
                  Distribution  Date occurs between and including  November 2005
                  and  October  2008,  and  30%  of  the  Original  Subordinated
                  Principal Balance if such Distribution Date occurs on or after
                  November  2008.  Except as provided  otherwise in this Section
                  4.2(h),  all  distributions  described  above  will be made in
                  accordance  with the priorities  set forth in Section  4.2(a),
                  (b) and (c).

         SECTION 4.3 Method of Distribution.

         (a)      All  distributions  with respect to each Class of Certificates
                  on each  Distribution  Date  shall be made pro rata  among the
                  outstanding   Certificates   of  such  Class,   based  on  the
                  Percentage   Interest  in  such  Class   represented  by  each
                  Certificate.   Payments  to  the  Certificateholders  on  each
                  Distribution   Date  will  be  made  by  the  Trustee  to  the
                  Certificateholders  of record on the  related  Record  Date by
                  check or money  order  mailed  to a  Certificateholder  at the


                                      -69-

                  address appearing in the Certificate Register, or upon written
                  request  by such  Certificateholder  to the  Trustee  made not
                  later than the  applicable  Record Date, by wire transfer to a
                  U.S. depository  institution  acceptable to the Trustee, or by
                  such other means of payment as such  Certificateholder and the
                  Trustee shall agree.

         (b)      Each  distribution  with respect to a  Book-Entry  Certificate
                  shall be paid to the Depository, which shall credit the amount
                  of  such  distribution  to  the  accounts  of  its  Depository
                  Participants  in accordance with its normal  procedures.  Each
                  Depository  Participant  shall be  responsible  for disbursing
                  such distribution to the Certificate Owners that it represents
                  and to each financial intermediary for which it acts as agent.
                  Each such  financial  intermediary  shall be  responsible  for
                  disbursing funds to the Certificate Owners that it represents.
                  All  such  credits  and   disbursements   with  respect  to  a
                  Book-Entry  Certificate  are to be made by the  Depository and
                  the Depository  Participants in accordance with the provisions
                  of the  applicable  Certificates.  Neither the Trustee nor the
                  Master Servicer shall have any responsibility  therefor except
                  as otherwise provided by applicable law.

         (c)      The  Trustee  shall  withhold  or  cause to be  withheld  such
                  amounts as it reasonably  determines  are required by the Code
                  (giving full effect to any  exemptions  from  withholding  and
                  related   certifications   required   to   be   furnished   by
                  Certificateholders or Certificate Owners and any reductions to
                  withholding  by virtue of any  bilateral  tax treaties and any
                  applicable   certification   required  to  be   furnished   by
                  Certificateholders or Certificate Owners with respect thereto)
                  from  distributions  to be made to  Non-U.S.  Persons.  If the
                  Trustee   reasonably   determines   that   a   more   accurate
                  determination  of the amount  required  to be  withheld  for a
                  distribution can be made within a reasonable  period after the
                  scheduled  date  for  such  distribution,  it  may  hold  such
                  distribution  in trust for a Holder of a Residual  Certificate
                  until such determination can be made. For the purposes of this
                  paragraph, a "Non-U.S. Person" is (i) an individual other than
                  a  citizen  or   resident  of  the  United   States,   (ii)  a
                  partnership, corporation or entity treated as a partnership or
                  corporation  for U.S.  federal  income tax purposes not formed
                  under the laws of the United States,  any state thereof or the
                  District of Columbia  (unless,  in the case of a  partnership,
                  Treasury regulations provide otherwise), (iii) any estate, the
                  income  of  which  is  not  subject  to  U.S.  federal  income
                  taxation, regardless of source, and (iv) any trust, other than
                  a trust  that a court  within  the  United  States  is able to
                  exercise primary  supervision over the  administration  of the
                  trust  and one or more  U.S.  Persons  have the  authority  to
                  control all substantial decisions of the trust.

         SECTION 4.4 Allocation of Losses.

         (a)      On or prior to each  Determination  Date, the Master  Servicer
                  shall  determine the amount of any Realized Loss in respect of
                  each  Mortgage  Loan  that  occurred  during  the  immediately
                  preceding calendar month.

         (b)      With respect to any Distribution  Date, the principal  portion
                  of each  Realized  Loss  (other  than any  Excess  Loss)  with
                  respect to a Mortgage Pool shall be allocated in the following
                  order of priority:

                  (i)      to  the  Class  B-6  Certificates   until  the  Class
                           Certificate Balance thereof has been reduced to zero;

                  (ii)     to  the  Class  B-5  Certificates   until  the  Class
                           Certificate Balance thereof has been reduced to zero;

                  (iii)    to  the  Class  B-4  Certificates   until  the  Class
                           Certificate Balance thereof has been reduced to zero;

                  (iv)     to  the  Class  B-3  Certificates   until  the  Class
                           Certificate Balance thereof has been reduced to zero;

                  (v)      to  the  Class  B-2  Certificates   until  the  Class
                           Certificate Balance thereof has been reduced to zero;

                  (vi)     to  the  Class  B-1  Certificates   until  the  Class
                           Certificate Balance thereof has been reduced to zero;

                  (vii)    to the Classes of Senior  Certificates of the related
                           Certificate Group, pro rata, in accordance with their
                           Class Certificate Balances;  provided,  that from and
                           after the  Cross-over  Date the principal  portion of
                           Realized  Losses  (other than  Excess  Losses) on the
                           Mortgage   Loans   allocable   to  the  Class   I-A-1
                           Certificates  shall  instead  be  borne  first by the
                           Class I-A-2  Certificates until the Class Certificate
                           Balance  thereof is reduced to zero (in  addition  to
                           other  Realized  Losses  allocable to the Class I-A-2
                           Certificates),   and   not   by   the   Class   I-A-1
                           Certificates,  for so long as the  Class  Certificate
                           Balance of the Class  I-A-2  Certificates  is greater
                           than zero.

         (c)      With respect to any Distribution  Date, the principal  portion
                  of any Excess Loss with respect to a Mortgage Pool (other than
                  Excess   Bankruptcy   Losses   attributable  to  Debt  Service
                  Reductions)  shall  be  allocated  pro  rata to each  Class of
                  Certificates of the related  Certificate  Group based on their
                  respective  Class  Certificate  Balances  (in the  case of the
                  Senior Certificates) or Apportioned Principal Balances (in the
                  case of the Subordinated Certificates).

         (d)      Any  Realized  Losses  allocated  to a Class  of  Certificates
                  pursuant to Section 4.4(b) or (c) shall be allocated among the
                  Certificates  of such Class in proportion to their  respective
                  Certificate  Principal  Balances.  Any  allocation of Realized
                  Losses pursuant to this paragraph (d) shall be accomplished by
                  reducing  the  Certificate  Principal  Balances of the related
                  Certificates  on the related  Distribution  Date in accordance
                  with Section 4.4(e).

         (e)      Realized Losses  allocated in accordance with this Section 4.4
                  shall  be  allocated  on the  Distribution  Date in the  month
                  following  the month in which such loss was  incurred  and, in
                  the case of the principal portion thereof, after giving effect
                  to the distributions made on such Distribution Date.

         (f)      On each Distribution Date, the Master Servicer shall determine
                  the Subordinated  Certificate  Writedown  Amount,  if any. Any
                  such Subordinated  Certificate  Writedown Amount shall effect,
                  without duplication of any other provision in this Section 4.4
                  that provides for a reduction in the Class Certificate Balance
                  of the Subordinated Certificates, a corresponding reduction in
                  the   Class   Certificate    Balance   of   the   Subordinated
                  Certificates, which reduction shall occur on such Distribution
                  Date  after  giving  effect  to  distributions  made  on  such
                  Distribution Date.

         (g)      Notwithstanding  the  foregoing,  no  such  allocation  of any
                  Realized Loss shall be made on a Distribution  Date to a Class
                  of  Certificates  to the  extent  that such  allocation  would
                  result in the  reduction of the  aggregate  Class  Certificate
                  Balances  of  all  the  Senior   Certificates   of  a  related
                  Certificate  Group  as of  such  Distribution  Date  plus  the
                  Apportioned    Principal    Balances   of   the   Subordinated
                  Certificates of such Certificate Group as of such Distribution
                  Date,  after  giving  effect  to all  distributions  and prior
                  allocations of Realized Losses on such date, to an amount less
                  than the aggregate  Stated  Principal  Balance of the Mortgage
                  Loans in the related  Mortgage Pool as of the first day of the
                  month of such Distribution Date, less any Deficient Valuations
                  occurring on or prior to the Bankruptcy  Coverage  Termination
                  Date (such limitation, the "Loss Allocation Limitation").

         SECTION 4.5 [RESERVED]

         SECTION 4.6 Monthly Statements to Certificateholders.

         (a)      Not later  than each  Distribution  Date,  the  Trustee  shall
                  prepare and cause to be  forwarded by first class mail to each
                  Certificateholder, the Master Servicer, the Depositor and each
                  Rating  Agency a statement  setting  forth with respect to the
                  related  distribution  and/or may post such  statement  on its
                  website located at www.mbsreporting.com:

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

                  (ii)     the amount thereof allocable to interest,  the amount
                           of  any  Compensating   Interest   included  in  such
                           distribution   and   any   remaining   Net   Interest
                           Shortfalls 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;

         (b)      The  Trustee's   responsibility   for   disbursing  the  above
                  information  to  the  Certificateholders  is  limited  to  the

                  Business  Day prior to the  related  Distribution  Date),  the

         (d)      Within  a  reasonable  period  of time  after  the end of each

                  4.6  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.

                                    ARTICLE V
                                THE CERTIFICATES

         SECTION 5.1 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 9.2 hereof respecting the final  distribution on the
Certificates,  on each Distribution Date the Trustee shall make distributions to
each Certificateholder of record on the preceding Record Date either (x) by wire
transfer in immediately  available funds to the account of such Holder at a bank
or other entity having appropriate  facilities therefor,  if (i) such Holder has
so notified the Trustee at least five Business Days prior to the related  Record
Date and (ii) such Holder shall hold (A) 100% of the Class  Certificate  Balance
of any Class of  Certificates  or (B)  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.


                                      -74-

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

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

         SECTION 5.2 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  5.6  hereof,  a
                  Certificate  Register for the Trust Fund in which,  subject to
                  the  provisions of  subsections  (b) and (c) below and to such
                  reasonable regulations as it may prescribe,  the Trustee shall
                  provide for the  registration of Certificates and of transfers
                  and  exchanges  of  Certificates  as  herein  provided.   Upon
                  surrender for registration of transfer of any Certificate, the
                  Trustee  shall  execute  and  deliver,  in  the  name  of  the
                  designated   transferee  or  transferees,   one  or  more  new
                  Certificates  of  the  same  Class  and  aggregate  Percentage
                  Interest.

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

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

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

         (b)      No transfer of a Private Certificate shall be made unless such
                  transfer  is  made  pursuant  to  an  effective   registration
                  statement  under the Securities  Act and any applicable  state
                  securities   laws  or  is   exempt   from   the   registration
                  requirements under said Act and such state securities laws. In
                  the event that a transfer  is to be made in  reliance  upon an
                  exemption  from the  Securities Act and such laws, in order to
                  assure  compliance  with the Securities Act and such laws, any
                  Holder  of  a  Private   Certificate  (other  than  a  Private
                  Certificate  that is a  Book-Entry  Certificate)  desiring  to
                  effect such transfer and such Certificateholder's  prospective
                  transferee  shall each  certify to the  Trustee in writing the
                  facts  surrounding the transfer in substantially the forms set
                  forth in  Exhibit  I (the  "Transferor  Certificate")  and (i)
                  deliver a letter in substantially the form of either Exhibit J
                  (the  "Investment  Letter")  or  Exhibit  K  (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.

                  Each  Holder of a  Private  Certificate  that is a  Book-Entry
         Certificate,  by its  acquisition  thereof  (or a  beneficial  interest
         therein),  shall be deemed to have  represented  and  warranted for the
         benefit of the  Depositor,  the  Servicer  and the Trustee  that (a) it
         understands  that the  Private  Certificates  are not being  registered
         under the Securities  Act, or any state  securities  laws and are being
         transferred to it in a transaction that is exempt from the registration
         requirements  of the  Securities Act and any such laws, (b) it has such
         knowledge and  experience in financial and business  matters that it is
         capable  of  evaluating  the  merits  and risks of  investments  in the
         Private  Certificates,  (c) it has had the opportunity to ask questions
         of and receive  answers from the Depositor  concerning  the purchase of
         the  Private  Certificates  and all  matters  relating  thereto  or any
         additional information deemed necessary to its decision to purchase the
         Private  Certificates,  (d)  neither  it, nor any anyone  acting on its
         behalf, has offered,  transferred,  pledged, sold or otherwise disposed
         of the Private  Certificates or any interest therein,  or solicited any
         offer to buy or accept a transfer,  pledge or other  disposition of the
         Private  Certificates  or  any  interest  therein  from,  or  otherwise
         approached or negotiated  with respect to the Private  Certificates  or
         any  interest  therein  with,  any  person in any  manner,  or made any
         general  solicitation  by means of general  advertising or in any other
         manner, or taken any other action, that would constitute a distribution
         of the  Private  Certificates  under the  Securities  Act or that would
         render the  disposition  of the Private  Certificates  a  violation  of
         Section  5 of the  Securities  Act  or  require  registration  pursuant
         thereto,  nor will it act, nor has it authorized or will  authorize any
         person to act, in such manner with respect to the Private Certificates,
         (e) it is a "qualified  institutional buyer" as that term is defined in
         Rule 144A under the Securities Act ("Rule 144A"),  (f) it is aware that
         the sale of the Private Certificates to it is being made in reliance on
         Rule 144A,  (g) it is acquiring  the Private  Certificates  for its own
         account or for resale pursuant to Rule 144A and it understands that the
         Private Certificates may be resold,  pledged or transferred only (A) to
         a person whom it  reasonably  believes to be a qualified  institutional
         buyer  that  purchases  for its own  account  or for the  account  of a
         qualified  institutional buyer to whom notice is given that the resale,
         pledge or  transfer  is being made in  reliance  on Rule  144A,  or (B)
         pursuant to another  exemption from  registration  under the Securities
         Act; and (h) it understands  that no  representation  is made as to the
         availability of the exemption  provided by Rule 144A for resales of the
         Private Certificates.

                  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 by its
         acceptance of a Private Certificate 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 (other than a
         Private  Certificate)  shall be made  unless  the  Trustee  shall  have
         received a  Transferor  Certificate  from the  related  transferor  and
         either (i) a  representation  from the  transferee of such  Certificate
         acceptable to and in form and substance satisfactory to the Trustee (in
         the event such Certificate is a Private  Certificate,  such requirement
         is satisfied only by the Trustee's  receipt of a representation  letter
         from the transferee  substantially  in the form of Exhibit J or Exhibit
         K), to the effect that such transferee is not an employee  benefit plan
         or arrangement subject to Section 406 of ERISA or a plan or arrangement
         subject to Section 4975 of the Code,  nor a person  acting on behalf of
         any such plan or arrangement,  nor using the assets of any such plan or
         arrangement  to  effect  such  transfer,  (ii) in the case of a Private
         Certificate (that has been subject to an ERISA-Qualified  Underwriting)
         or a Residual Certificate,  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
         Sections  I and III of 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,  the  Depositor,  the Master  Servicer 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  prohibited
         transactions  under  Section 406 of ERISA and Section  4975 of the Code
         and will not subject the Trustee,  the Depositor or the Master Servicer
         to any  obligation  in addition to those  expressly  undertaken in this
         Agreement or to any  liability.  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 5.2(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.

                  Each  Holder of a  Private  Certificate  that is a  Book-Entry
         Certificate,  by its  acquisition  thereof  (or a  beneficial  interest
         therein)  shall be deemed to have  represented  and  warranted  for the
         benefit of the  Depositor,  the  Servicer,  the  Trustee  and the other
         Certificateholders,  that  (a) it is not an  employee  benefit  plan or
         arrangement  that is  subject  to  Section  406 of ERISA,  or a plan or
         arrangement  that is subject to Section  4975 of the  Internal  Revenue
         Code of 1986,  as amended,  nor is it acting on behalf of any such plan
         or  arrangement  or using the assets of any such plan or arrangement to
         effect such acquisition,  or (b) if it is an insurance company,  in the
         case  of  Private  Certificates  that  have  been  the  subject  of  an
         ERISA-Qualifying   Underwriting,   it   is   purchasing   the   Private
         Certificates  with funds  contained in an  "insurance  company  general
         account" (as defined in Section V(e) of  Prohibited  Transaction  Class
         Exemption  95-60  ("PTCE  95-60"))  and its purchase and holding of the
         Private  Certificates  are  covered  under  Sections  I and III of PTCE
         95-60.

                  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 5.2(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 H.

                  (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  5.2(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  5.2(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  5.2(b)  and this  Section
                           5.2(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, in the case of
                           a  Residual  Certificate  which  is  also  a  Private
                           Certificate,  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  5.2(c) shall cease to apply (and the  applicable
         portions of the legend on a Residual  Certificate  may be deleted) with
         respect to  Transfers  occurring  after  delivery  to the Trustee of an
         Opinion of Counsel, which Opinion of Counsel shall not be an expense of
         the Trust Fund, the Trustee, the Seller or the Master Servicer,  to the
         effect that the  elimination  of such  restrictions  will not cause any
         REMIC created  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  5.2 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  Class  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 5.3 Mutilated, Destroyed, Lost or Stolen Certificates.

         If (a) any mutilated  Certificate is surrendered to the Trustee, or the
Trustee receives evidence to its satisfaction of the destruction,  loss or theft
of any  Certificate  and (b) there is delivered  to the Master  Servicer and the
Trustee  such  security or  indemnity as may be required by them to save each of
them  harmless,  then,  in the  absence  of  notice  to the  Trustee  that  such
Certificate  has been  acquired  by a bona fide  purchaser,  the  Trustee  shall
execute,  countersign  and  deliver,  in  exchange  for or in lieu  of any  such
mutilated,  destroyed,  lost or stolen  Certificate,  a new  Certificate of like
Class, tenor and Percentage Interest. In connection with the issuance of any new
Certificate under this Section 5.3, 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  5.3  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 5.4 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 5.5 Access to List of Certificateholders' Names and Addresses.

         If three or more  Certificateholders  or Certificate Owners (a) request
such   information   in  writing   from  the   Trustee,   (b)  state  that  such
Certificateholders  or  Certificate  Owners  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  or  Certificate  Owners  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  or Certificate  Owners 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  or  Certificate  Owner,  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 5.6 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.

                                   ARTICLE VI
                      THE DEPOSITOR AND THE MASTER SERVICER

         SECTION 6.1  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 6.2 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  6.3  Limitation  on  Liability  of the  Depositor,  the Master
Servicer and Others.

         None of the  Depositor,  the Master  Servicer or any of the  directors,
officers,  employees or agents of the Depositor 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 Master Servicer or any such Person against
any breach of  representations  or  warranties  made by it herein or protect the
Depositor, 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 Master Servicer and any
director, officer, employee or agent of the Depositor 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  Master  Servicer  and any  director,  officer,  employee  or  agent  of the
Depositor 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.  Neither the Depositor nor 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
either the Depositor, 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,  and the Master Servicer shall
be entitled to be reimbursed  therefor out of the  applicable  subaccount of the
Certificate Account.

         SECTION 6.4 Limitation on Resignation of Master Servicer.

         The Master  Servicer shall not resign from the  obligations  and duties
hereby  imposed on it except (a) upon  appointment  of a successor  servicer and
receipt  by the  Trustee  of a  letter  from  each  Rating  Agency  that  such a
resignation  and  appointment  will not result in a downgrading of the rating of
any of the Certificates, 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 other  successor  master  servicer
shall have assumed the Master Servicer's  responsibilities,  duties, liabilities
and obligations hereunder.

         SECTION 7.1 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
                           applicable  subaccount of the Certificate  Account or
                           remit to the Trustee any payment  required to be made
                           under  the  terms of this  Agreement,  which  failure
                           shall  continue  unremedied  for five days  after the
                           date upon which written  notice of such failure shall
                           have been given to the Master Servicer by the Trustee
                           or the  Depositor  or to the Master  Servicer and the
                           Trustee  by the  Holders of  Certificates  having not
                           less than 25% of the Voting  Rights  evidenced by the
                           Certificates; or

                  (ii)     any  failure  by the  Master  Servicer  to observe or
                           perform  in any  material  respect  any  other of the
                           covenants  or  agreements  on the part of the  Master
                           Servicer  contained in this Agreement,  which failure
                           materially affects the rights of  Certificateholders,
                           which failure continues unremedied for a period of 60
                           days after the date on which  written  notice of such
                           failure shall have been given to the Master  Servicer
                           by the  Trustee  or the  Depositor,  or to the Master
                           Servicer   and  the   Trustee   by  the   Holders  of
                           Certificates  evidencing  not  less  than  25% of the
                           Voting   Rights   evidenced   by  the   Certificates;
                           provided,  however, that the 60-day cure period shall
                           not apply to the  initial  delivery  of the  Mortgage
                           File  for  Delay  Delivery  Mortgage  Loans  nor  the
                           failure to  substitute or repurchase in lieu thereof;
                           or

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

                  (iv)     the Master  Servicer shall consent to the appointment
                           of  a  receiver  or  liquidator  in  any  insolvency,
                           readjustment  of  debt,  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; or

                  (vi)     the  failure  of the  Master  Servicer  to remit  any
                           Advance   required  to  be  remitted  by  the  Master
                           Servicer   pursuant  to  Section  4.1  which  failure
                           continues  unremedied at 11:00 a.m., Central time, on
                           the related Distribution Date.

         If an Event of Default  described in clauses (i) to (v) of this Section
shall  occur,  then,  and in each and every such case,  so long as such Event of
Default  shall not have been  remedied,  the Trustee may, or at the direction of
the  Holders  of  Certificates  evidencing  not less than 66 2/3% of the  Voting
Rights evidenced by the Certificates,  the Trustee shall by notice in writing to
the Master  Servicer (with a copy to each Rating  Agency),  terminate all of the
rights and obligations of the Master Servicer under this Agreement and in and to
the  Mortgage  Loans  and the  proceeds  thereof,  other  than its  rights  as a
Certificateholder  hereunder. If an Event of Default described in clause (vi) of
this Section shall occur, the Trustee shall immediately, 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  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 or another  successor to the Master Servicer  appointed by
the Trustee  pursuant to Section 7.2. The Trustee,  in its capacity as successor
to the  Master  Servicer,  shall  thereupon  make any  Advance  which the Master
Servicer  failed to make  subject to Section 4.1  hereof.  The Trustee is hereby
authorized  and  empowered  to  execute  and  deliver,  on behalf of the  Master
Servicer,  as  attorney-in-fact  or  otherwise,  any and all documents and other
instruments,  and to do or  accomplish  all other  acts or things  necessary  or
appropriate  to effect the  purposes of such notice of  termination,  whether to
complete the transfer and  endorsement  or assignment of the Mortgage  Loans and
related  documents,  or  otherwise.  Unless  expressly  provided in such written
notice,  no such termination  shall affect any obligation of the Master Servicer
to pay amounts owed  pursuant to Article  VIII.  The Master  Servicer  agrees to
cooperate with the Trustee in effecting the termination of the Master Servicer's
responsibilities  and  rights  hereunder,  including,  without  limitation,  the
transfer to the Trustee of all cash amounts  which shall at the time be credited
to the  Certificate  Account,  or  thereafter  be received  with  respect to the
Mortgage  Loans.  All expenses  incurred in the  transferring  of the  servicing
duties from the Master  Servicer to a  Successor  Servicer  shall be paid by the
Master  Servicer,  and if not paid by the  Master  Servicer,  shall be paid from
amounts on deposit in the Certificate Account.

         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  3.8(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.  Any termination of the activities of the Master  Servicer  hereunder
will simultaneously result in the termination of the Master Servicer's duties as
a  subservicer  pursuant  to the  Servicing  Rights  Transfer  and  Subservicing
Agreement.

         SECTION 7.2 Trustee to Act; Appointment of Successor.

         On and  after  the time  the  Master  Servicer  receives  a  notice  of
termination pursuant to Section 7.1 hereof, the Trustee shall, subject to and to
the extent  provided in Section  3.4, be the  successor  to the 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
4.1.  As  compensation  therefor,  the  Trustee  shall be  entitled to all funds
relating to the Mortgage Loans that the Master Servicer would have been entitled
to charge to the  Certificate  Account  or  Distribution  Account  if the Master
Servicer had continued to act hereunder.  Notwithstanding the foregoing,  if the
Trustee  has become the  successor  to the Master  Servicer in  accordance  with
Section 7.1  hereof,  the Trustee  may, if it shall be  unwilling  to so act, or
shall,  if it is prohibited by applicable law from making  Advances  pursuant to
Section 4.1 hereof or if it is otherwise unable to so act, appoint,  or petition
a court of competent  jurisdiction  to appoint,  any  established  mortgage loan
servicing  institution  the  appointment of which does not adversely  affect the
then current rating of the  Certificates  by each Rating Agency as the successor
to the Master  Servicer  hereunder in the  assumption  of all or any part of the
responsibilities,  duties or liabilities of the Master Servicer  hereunder.  Any
successor to the Master  Servicer  shall be an  institution  which is a FNMA and
FHLMC approved  seller/servicer  in good  standing,  which has a net worth of at
least  $10,000,000,  and which is  willing  to service  the  Mortgage  Loans and
executes and delivers to the  Depositor  and the Trustee an agreement  accepting
such delegation and  assignment,  which contains an assumption by such Person of
the rights, powers, duties, responsibilities, obligations and liabilities of the
Master Servicer (other than liabilities of the Master Servicer under Section 6.3
hereof  incurred prior to termination of the Master Servicer under Section 7.1),
with  like  effect  as if  originally  named as a party to this  Agreement;  and
provided  further that each Rating  Agency  acknowledges  that its rating of the
Certificates in effect  immediately prior to such assignment and delegation will
not be  qualified or reduced,  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 3.4 hereof,  act in such  capacity as provided  above.  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 3.18.

<PAGE>

         In  connection  with  the  termination  or  resignation  of the  Master
Servicer  hereunder,  either (i) the successor  Master  Servicer,  including the
Trustee if the Trustee is acting as successor Master  Servicer,  shall represent
and  warrant  that it is a member of MERS in good  standing  and shall  agree to
comply  in all  material  respects  with the  rules  and  procedures  of MERS in
connection  with the servicing of the Mortgage  Loans that are  registered  with
MERS, or (ii) the predecessor Master Servicer shall cooperate with the successor
Master  Servicer either (x) in causing MERS to execute and deliver an assignment
of Mortgage in recordable form to transfer the Mortgage from MERS to the Trustee
and to execute and deliver such other notices,  documents and other  instruments
as may be necessary or desirable to effect a transfer of such  Mortgage  Loan or
servicing of such  mortgage Loan on the MERS(R)  System to the successor  Master
Servicer or (y) in causing MERS to designate on the MERS(R) System the successor
Master  Servicer as the servicer of such Mortgage Loan. The  predecessor  Master
Servicer shall file or cause to be filed any such  assignment in the appropriate
recording  office.  The successor Master Servicer shall cause such assignment to
be delivered to the Trustee  promptly upon receipt of the original with evidence
of recording thereon or a copy certified by the public recording office in which
such assignment was recorded.

         SECTION 7.3 Notification to Certificateholders.

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

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

                                  ARTICLE VIII
                             CONCERNING THE TRUSTEE

         SECTION 8.1 Duties of Trustee.

         The Trustee,  prior to the occurrence of an Event of Default of which a
Responsible  Officer of the Trustee has actual knowledge 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 of which a  Responsible  Officer  of the  Trustee  has
actual  knowledge 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.  If any such


                                      -87-
<PAGE>

instrument is found not to conform in any material  respect to the  requirements
of this  Agreement,  the Trustee  shall  notify the  Certificateholders  of such
instrument in the event that the Trustee, after so requesting,  does not receive
a satisfactorily corrected instrument.

         The Trustee is hereby directed to execute and deliver to The Depository
Trust Company the Issuer Letter of Representations  dated as of the Closing Date
on behalf of the trust created hereunder.  The Depositor and the Master Servicer
acknowledge  and agree that the Trustee is executing and  delivering  the Issuer
Letter of  Representations on behalf of the trust created hereunder and shall do
so solely in its capacity as Trustee and not in its individual capacity.

         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  of which a  Responsible
                           Officer of the  Trustee  has actual  knowledge  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;

                  (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;

                  (iv)     the  Trustee  shall not be required to expend or risk
                           its own funds or otherwise incur financial  liability
                           in the performance of any of its duties  hereunder or
                           the  exercise of any of its rights or powers if there
                           is reasonable ground for believing that the repayment
                           of such funds or adequate indemnity against such risk
                           or  liability  is not  assured to it, and none of the
                           provisions  contained in this Agreement  shall in any
                           event   require  the   Trustee  to  perform,   or  be
                           responsible  for the manner of performance of, any of

                           Agreement  except  during  such time,  if any, as the
                           Trustee shall be the successor to, and be vested with
                           the rights,  duties,  powers and  privileges  of, the
                           Master Servicer; and

                  (v)      without  limiting the generality of this Section 8.1,
                           the  Trustee  shall  have no  duty  (A) to see to any
                           recording, filing, or depositing of this Agreement or
                           any  agreement  referred  to herein or any  financing
                           statement  or  continuation  statement  evidencing  a
                           security  interest,  or to see to the  maintenance of
                           any such  recording  or filing or  deposit  or to any
                           rerecording, refiling or redepositing of any thereof,
                           (B)  to  see  to  any  insurance,  (C)  to see to the
                           payment or discharge of any tax, assessment, or other
                           governmental charge or any lien or encumbrance of any
                           kind  owing  with  respect  to,  assessed  or  levied
                           against,  any part of the Trust  Fund other than from
                           funds  available in the  Distribution  Account (D) to
                           confirm  or verify  the  contents  of any  reports or
                           certificates of the Servicer delivered to the Trustee
                           pursuant to this Agreement believed by the Trustee to
                           be genuine  and to have been signed or  presented  by
                           the proper party or parties.

         SECTION 8.2 Certain Matters Affecting the Trustee.

                           any resolution, Officers' Certificate, certificate of

                           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

                           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;  provided, however, that if the payment
                           within a reasonable time to the Trustee of the costs,
                           expenses or  liabilities  likely to be incurred by it
                           in  the  making  of  such  investigation  is,  in the
                           opinion of the Trustee, not assured to the Trustee by
                           the  security  afforded  to it by the  terms  of this
                           Agreement,   the  Trustee   may   require   indemnity
                           satisfactory   to  the  Trustee  against  such  cost,
                           expense or  liability  as a  condition  to taking any
                           such  action.  The  reasonable  expense of every such
                           examination  shall be paid by the Master Servicer or,
                           if paid by the Trustee, shall be repaid by the Master
                           Servicer upon demand from the Servicer's own funds.

                  (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  and the Trustee  shall not be  responsible
                           for any  misconduct or negligence on the part of such
                           agent,   accountant  or  attorney  appointed  by  the
                           Trustee with due care;

                  (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 in  the  absence  of  such  notice,  the
                           Trustee  may  conclusively  assume  that  there is no
                           Event of Default;

                  (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;

                  (x)      the right of the Trustee to perform any discretionary
                           act  enumerated  in  this  Agreement   shall  not  be
                           construed  as a duty,  and the  Trustee  shall not be
                           answerable  for other than its  negligence or willful
                           misconduct in the performance of such act; and

<PAGE>

                  (xi)     the Trustee shall not be required to give any bond or
                           surety in respect of the  execution of the Trust Fund
                           created hereby or the powers granted hereunder.

         SECTION 8.3 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 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 or of MERS or the MERS(R) System other than with respect to the
Trustee's execution and counter-signature of the Certificates. The Trustee shall
not be  accountable  for the use or  application  by the Depositor or the Master
Servicer of any funds paid to the Depositor or the Master Servicer in respect of
the Mortgage Loans or deposited in or withdrawn from the Certificate  Account by
the Depositor or the Master Servicer.

         SECTION 8.4 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 8.5 Trustee's Fees and Expenses.

         The Trustee,  as  compensation  for its activities  prior to making the
distributions  pursuant to Section 4.2 hereunder,  shall be entitled to withdraw
from the Distribution  Account on each  Distribution Date an amount equal to the
Trustee Fee for such Distribution  Date. The Trustee and any director,  officer,
employee or agent of the Trustee shall be indemnified by the Master Servicer and
held  harmless  against any loss,  liability  or expense  (including  reasonable
attorney's  fees) (i)  incurred  in  connection  with any claim or legal  action
relating to (a) this Agreement,  (b) the  Certificates or (c) in connection with
the performance of any of the Trustee's duties  hereunder,  other than any loss,
liability  or expense  incurred by reason of willful  misfeasance,  bad faith or
negligence  in the  performance  of any of the  Trustee's  duties  hereunder  or
incurred by reason of any action of the Trustee  taken at the  direction  of the
Certificateholders  and (ii)  resulting from any error in any tax or information
return  prepared  by the Master  Servicer.  Such  indemnity  shall  survive  the
termination  of this  Agreement  or the  resignation  or removal of the  Trustee
hereunder.  Without  limiting the foregoing,  the Master Servicer  covenants and
agrees,  except as  otherwise  agreed upon in writing by the  Depositor  and the
Trustee,  and except for any such expense,  disbursement or advance as may arise
from the  Trustee's  negligence,  bad  faith or  willful  misconduct,  to pay or
reimburse the Trustee, for all reasonable  expenses,  disbursements and advances
incurred or made by the Trustee in accordance with any of the provisions of this
Agreement with respect to: (A) the reasonable  compensation and the expenses and
disbursements  of its counsel not associated with the closing of the issuance of
the Certificates, (B) the reasonable compensation, expenses and disbursements of
any  accountant,  engineer or appraiser  that is not  regularly  employed by the
Trustee, to the extent that the Trustee must engage such persons to perform acts
or services hereunder and (C) printing and engraving expenses in connection with
preparing any Definitive Certificates.  Except as otherwise provided herein, the
Trustee  shall not be  entitled  to payment  or  reimbursement  for any  routine
ongoing expenses incurred by the Trustee in the ordinary course of its duties as
Trustee,  Registrar,  Tax Matters  Person or Paying  Agent  hereunder or for any
other expenses.

         SECTION 8.6 Eligibility Requirements for Trustee.

         The  Trustee   hereunder  shall  at  all  times  be  a  corporation  or
association organized and doing business under the laws of a state or the United
States of  America,  authorized  under  such laws to  exercise  corporate  trust
powers,  having a combined capital and surplus of at least $50,000,000,  subject
to 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).  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 8.6 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 8.6, the Trustee  shall resign
immediately  in the manner and with the effect  specified in Section 8.7 hereof.
The entity  serving as Trustee may have normal  banking and trust  relationships
with the Depositor and its affiliates or the Master Servicer and its affiliates;
provided,  however,  that such  entity  cannot  be an  affiliate  of the  Master
Servicer other than the Trustee in its role as successor to the Master Servicer.

         SECTION 8.7 Resignation and Removal of Trustee.

         The Trustee may at any time  resign and be  discharged  from the trusts
hereby  created by giving written notice of resignation to the Depositor and the
Master  Servicer  and each  Rating  Agency not less than 60 days before the date
specified in such notice when,  subject to Section 8.8, such  resignation  is to
take effect,  and acceptance by a successor  trustee in accordance  with Section
8.8 meeting the qualifications set forth in Section 8.6. 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 8.6 hereof and shall fail to resign after written
request  thereto by the  Depositor,  or if at any time the Trustee  shall become
incapable  of acting,  or shall be  adjudged  as  bankrupt  or  insolvent,  or a
receiver of the Trustee or of its  property  shall be  appointed,  or any public
officer  shall  take  charge or control of the  Trustee  or of its  property  or
affairs for the purpose of rehabilitation, conservation or liquidation, or a tax
is imposed  with  respect to the Trust Fund by any state in which the Trustee or
the Trust Fund is located and the imposition of such tax would be avoided by the
appointment of a different  trustee,  then the Depositor or the Master  Servicer
may remove the Trustee and appoint a successor trustee by written instrument, in
triplicate,  one copy of which instrument shall be delivered to the Trustee, one
copy of which  shall be  delivered  to the Master  Servicer  and one copy to the
successor trustee.


                                      -92-
<PAGE>

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

         Any  resignation  or  removal  of  the  Trustee  and  appointment  of a
successor  trustee  pursuant to any of the  provisions of this Section 8.7 shall
become  effective upon  acceptance of  appointment  by the successor  trustee as
provided in Section 8.8 hereof.

         SECTION 8.8 Successor Trustee.

         Any successor trustee appointed as provided in Section 8.7 hereof shall
execute, acknowledge and deliver to the Depositor and to its predecessor trustee
and the Master Servicer an instrument  accepting such appointment  hereunder and
thereupon the  resignation  or removal of the  predecessor  trustee shall become
effective  and  such  successor  trustee,  without  any  further  act,  deed  or
conveyance,  shall become fully vested with all the rights,  powers,  duties and
obligations of its predecessor hereunder,  with the like effect as if originally
named as trustee herein. The Depositor,  the Master Servicer and the predecessor
trustee shall execute and deliver such  instruments  and do such other things as
may  reasonably be required for more fully and certainly  vesting and confirming
in the successor trustee all such rights, powers, duties, and obligations.

         No  successor  trustee  shall  accept  appointment  as provided in this
Section 8.8 unless at the time of such acceptance  such successor  trustee shall
be eligible under the provisions of Section 8.6 hereof and its appointment shall
not adversely affect the then current rating of the Certificates.

         Upon  acceptance of appointment  by a successor  trustee as provided in
this Section  8.8, 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 8.9 Merger or Consolidation of Trustee.

         Any  corporation  into which the Trustee may be merged or  converted or
with which it may be consolidated or any corporation  resulting from any merger,
conversion  or  consolidation  to which  the  Trustee  shall be a party,  or any
corporation succeeding to the business of the Trustee, shall be the successor of
the Trustee  hereunder,  provided that such corporation  shall be eligible under
the  provisions  of Section 8.6 hereof  without the  execution  or filing of any
paper or further act on the part of any of the parties  hereto,  anything herein
to the contrary notwithstanding.

         SECTION 8.10 Appointment of Co-Trustee or Separate Trustee.

         Notwithstanding  any other  provisions of this Agreement,  at any time,
for the purpose of meeting any legal  requirements of any  jurisdiction in which
any part of the Trust Fund or property  securing  any  Mortgage  Note may at the


                                      -93-
<PAGE>

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 8.6 and no
notice to  Certificateholders  of the  appointment of any co-trustee or separate
trustee shall be required under Section 8.8.

         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
                           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  each  REMIC
election  is to be  made,  as set  forth  in  the  preliminary  statement  shall
constitute,  and that the conduct of matters  relating  to such assets  shall be
such as to qualify such assets as, a "real estate mortgage  investment  conduit"
as defined in and in accordance  with the REMIC  Provisions.  In  furtherance of
such intention, the Trustee covenants and agrees that it shall act as agent (and
the Trustee is hereby appointed to act as agent) on behalf of any such REMIC and
that in such  capacity it shall:  (a) prepare and file,  or cause to be prepared
and filed, in a timely manner,  a U.S. Real Estate Mortgage  Investment  Conduit
Income  Tax Return  (Form 1066 or any  successor  form  adopted by the  Internal
Revenue Service) and prepare and file or cause to be prepared and filed with the
Internal  Revenue Service and applicable  state or local tax authorities  income
tax or information returns for each taxable year with respect to any such REMIC,
containing  such  information  and at the  times  and  in the  manner  as may be
required  by the Code or state or local tax  laws,  regulations,  or rules,  and
furnish or cause to be furnished to Certificateholders the schedules, statements
or information at such times and in such manner as may be required thereby;  (b)
within thirty days of the Closing Date,  furnish or cause to be furnished to the
Internal Revenue  Service,  on Forms 8811 or as otherwise may be required by the
Code,  the name,  title,  address,  and telephone  number of the person that the
Holders of the  Certificates may contact for tax information  relating  thereto,
together with such  additional  information as may be required by such Form, and
update such information at the time or times in the manner required by the Code;
(c) make or cause to be made elections that such assets be treated as a REMIC on
the federal tax return for its first  taxable  year (and,  if  necessary,  under
applicable  state law);  (d) prepare and  forward,  or cause to be prepared  and
forwarded, to the Certificateholders and to the Internal Revenue Service and, if
necessary,  state tax  authorities,  all information  returns and reports as and
when  required to be provided to them in accordance  with the REMIC  Provisions,
including  without  limitation,  the  calculation of any original issue discount
using the  prepayment  assumption;  (e) provide  information  necessary  for the
computation of tax imposed on the transfer of a Residual Certificate to a Person
that is not a Permitted Transferee,  or an agent (including a broker, nominee or
other  middleman) of a  Non-Permitted  Transferee,  or a pass-through  entity in
which a  Non-Permitted  Transferee  is the  record  holder of an  interest  (the
reasonable cost of computing and furnishing  such  information may be charged to


                                      -95-
<PAGE>

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 any REMIC status;  (h) pay,
from the sources  specified  in the last  paragraph of this  Section  8.11,  the
amount of any federal or state tax,  including  prohibited  transaction taxes as
described below,  imposed on any such REMIC prior to its termination when and as
the same shall be due and  payable  (but such  obligation  shall not prevent the
Trustee  or any  other  appropriate  Person  from  contesting  any  such  tax in
appropriate  proceedings  and shall not  prevent the  Trustee  from  withholding
payment  of  such  tax,  if  permitted  by  law,  pending  the  outcome  of such
proceedings);  (i) ensure that federal, state or local income tax or information
returns  shall be signed by the Trustee or such other  person as may be required
to sign such returns by the Code or state or local laws,  regulations  or rules;
(j) maintain  records  relating to any such REMIC,  including but not limited to
the income,  expenses,  assets and liabilities thereof and the fair market value
and adjusted basis of the assets determined at such intervals as may be required
by the Code,  as may be necessary to prepare the foregoing  returns,  schedules,
statements  or  information;  and (k) as and  when  necessary  and  appropriate,
represent any such REMIC in any administrative or judicial  proceedings relating
to an  examination or audit by any  governmental  taxing  authority,  request an
administrative  adjustment as to any taxable year of any such REMIC,  enter into
settlement agreements with any governmental taxing agency, extend any statute of
limitations  relating to any tax item of any such REMIC,  and  otherwise  act on
behalf of any such REMIC in relation to any tax matter or controversy  involving
it.

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

         In the event that any tax is imposed on  "prohibited  transactions"  of
any REMIC as defined in Section  860F(a)(2) of the Code, on the "net income from
foreclosure property" of any REMIC as defined in Section 860G(c) of the Code, on
any  contribution to any REMIC after the Startup Day pursuant to Section 860G(d)
of the Code, or any other tax is imposed,  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 which breach was caused by its negligence or willful  misconduct,
(ii) the Master  Servicer,  in the case of any such  minimum tax, or if such tax
arises out of or results  from a breach by the Master  Servicer  of any of their
obligations  under this Agreement,  (iii) the Seller, if any such tax arises out
of or results  from the  Seller's  obligation  to  repurchase  a  Mortgage  Loan
pursuant to Section 2.2 or 2.3 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 3.8(b).

         SECTION 8.12 Periodic Filings.

         The Depositor hereby directs the Trustee to prepare,  execute (pursuant
to a limited power of attorney  given to the Trustee by the  Depositor) and file
on behalf of the Depositor all periodic  reports  required  under the Securities
Exchange  Act of 1934 in  conformity  with the terms of the  "no-action"  relief
granted  by  the  SEC  to  issuers  of  asset-backed   securities  such  as  the
Certificates  and the Trustee  hereby agrees to do so. The Master  Servicer will
also  prepare and execute any  certifications  to be filed with the Form 10-K as
required  under  the   Sarbanes-Oxley  Act  of  2002.  In  connection  with  the
preparation  and filing of such periodic  reports,  the Depositor and the Master
Servicer shall timely provide to the Trustee all material information  available
to them which is required  to be included in such  reports and not known to them
to be in the possession of the Trustee and such other information as the Trustee
reasonably  may  request  from  either of them and  otherwise  reasonably  shall
cooperate with the Trustee.  The Trustee shall have no liability with respect to
any failure to properly prepare or file such periodic reports  resulting from or
relating to the  Trustee's  inability or failure to obtain any  information  not
resulting from its own negligence or willful misconduct.

                                   ARTICLE IX
                                   TERMINATION

         SECTION 9.1  Termination  upon  Liquidation or Purchase of all Mortgage
Loans.

         Subject to Section 9.3, 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 a  Mortgage  Loan  that  has been
foreclosed and subject to clause (ii)) plus one month's accrued interest thereon
at the applicable  Adjusted  Mortgage Rate, (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,  plus  accrued and unpaid  interest
thereon  at the  applicable  Adjusted  Mortgage  Rate,  and  (iii) any costs and
damages  incurred  by the Trust in  connection  with the  noncompliance  of such
Mortgage Loan with any specifically applicable predatory or abusive lending law,
and (b) the later of (i) the maturity or other  liquidation (or any Advance with
respect  thereto) of the last Mortgage Loan  remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to  Certificateholders
of all amounts required to be distributed to them pursuant to this Agreement. In
no event shall the trusts created hereby  continue beyond the earlier of (i) the
expiration  of 21 years from the death of the  survivor  of the  descendants  of
Joseph P. Kennedy,  the late Ambassador of the United States to the Court of St.
James's,  living on the date hereof, and (ii) the Latest Possible Maturity Date.
The right to purchase all Mortgage Loans and REO  Properties  pursuant to clause
(a) above shall be conditioned upon the aggregate of the Pool Principal Balances
for each Mortgage  Pool, at the time of any such  repurchase,  aggregating  less
than ten percent of the aggregate Cut-off Date Pool Principal Balance of all the
Mortgage Pools.

         SECTION 9.2 Final Distribution on the Certificates.

         If on any Determination Date, the Master Servicer determines that there
are no Outstanding Mortgage Loans and no other funds or assets in the Trust Fund
other  than the funds in the  Certificate  Account,  the Master  Servicer  shall
direct  the  Trustee  promptly  to  send a  final  distribution  notice  to each
Certificateholder.  If the Master  Servicer  elects to terminate  the Trust Fund
pursuant to clause (a) of Section 9.1, 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 10th
day and no later than the 15th day of the month next preceding the month of such
final distribution. Any such notice shall specify (a) the Distribution Date upon
which final  distribution on the Certificates will be made upon presentation and
surrender of  Certificates at the office therein  designated,  (b) the amount of
such final distribution,  (c) the location of the office or agency at which such
presentation  and surrender must be made, and (d) that the Record Date otherwise
applicable to such Distribution Date is not applicable, distributions being made
only upon  presentation  and surrender of the Certificates at the office therein
specified.  The Master  Servicer  will give such notice to each Rating Agency at
the time such notice is given to Certificateholders.

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

         Upon presentation and surrender of the Certificates,  the Trustee shall
cause to be distributed to the  Certificateholders  of each Class,  in the order
set forth in Section 4.2 hereof, on the final  Distribution Date, 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 Class  Certificate  Balance thereof
plus accrued interest  thereon in the case of an interest  bearing  Certificate,
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


                                      -98-
<PAGE>

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 Holders of each of the
Class I-A-R  Certificates  shall be entitled  to all  unclaimed  funds and other
assets of the Trust  Fund,  held for  distribution  to such  Certificateholders,
which remain subject hereto.

         SECTION 9.3 Additional Termination Requirements.

         (a)      In the event the Master Servicer exercises its purchase option
                  as  provided  in  Section  9.1,  the Trust Fund and each REMIC
                  created  hereunder  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 9.3 will not (i) result in
                  the  imposition of taxes on "prohibited  transactions"  on any
                  REMIC as defined in  Section  860F of the Code,  or (ii) cause
                  any REMIC to fail to  qualify  as a REMIC at any time that any
                  Certificates are outstanding:

                                    (1)  Within  90  days  prior  to  the  final
                           Distribution  Date set forth in the  notice  given by
                           the Master  Servicer  under  Section  9.2, 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 for each REMIC created
                           hereunder  which,  as  evidenced  by  an  Opinion  of
                           Counsel addressed to the Trustee (which opinion shall
                           not be an expense of the  Trustee or the Tax  Matters
                           Person),   meets  the  requirements  of  a  qualified
                           liquidation; and

                                    (2)   Within  90  days  after  the  time  of
                           adoption of such plans 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 9.1.

         (b)      The  Trustee  as agent  for any  REMIC  established  hereunder
                  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  9.3(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 plans of complete liquidation.

                            MISCELLANEOUS PROVISIONS

         SECTION 11.1 Amendment.

         This Agreement may be amended from time to time by the  Depositor,  the
Master   Servicer   and  the   Trustee   without  the  consent  of  any  of  the
Certificateholders  (i) to cure any  ambiguity  or mistake,  (ii) to correct any
defective  provision  herein or to supplement any provision  herein which may be
inconsistent with any other provision herein,  (iii) to add to the duties of the
Depositor,  the Seller or the Master Servicer,  (iv) to add any other provisions
with respect to matters or questions arising hereunder or (v) to modify,  alter,
amend,  add to or  rescind  any of the  terms or  provisions  contained  in this
Agreement;  provided that any action pursuant to clauses (iv) or (v) above shall
not, as  evidenced  by an Opinion of Counsel  delivered  to the  Trustee  (which
Opinion of Counsel  shall not be an expense of the  Trustee or the Trust  Fund),
adversely affect in any material respect the interests of any Certificateholder;
provided, however, that the amendment shall not be deemed to adversely affect in
any  material  respect the  interests  of the  Certificateholders  if the Person
requesting  the amendment  obtains a letter from each Rating Agency stating that
the  amendment  would  not  result  in  the  downgrading  or  withdrawal  of the
respective  ratings then assigned to the  Certificates;  it being understood and
agreed that any such letter in and of itself will not represent a  determination
as to the  materiality of any such amendment and will represent a  determination
only as to the  credit  issues  affecting  any such  rating.  The  Trustee,  the
Depositor  and the  Master  Servicer  also may at any time and from time to time
amend this Agreement  without the consent of the  Certificateholders  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
or helpful to (i) maintain the qualification of any REMIC established  hereunder
as a REMIC under the Code,  (ii) avoid or minimize the risk of the imposition of
any tax on any REMIC established  hereunder pursuant to the Code that would be a
claim at any time prior to the final  redemption  of the  Certificates  or (iii)
comply with any other  requirements  of the Code,  provided that the Trustee has
been  provided an Opinion of Counsel,  which  opinion shall be an expense of the
party  requesting  such  opinion  but in any case shall not be an expense of the
Trustee  or the Trust  Fund,  to the effect  that such  action is  necessary  or
helpful  to, as  applicable,  (i)  maintain  such  qualification,  (ii) avoid or
minimize the risk of the  imposition of such a tax or (iii) comply with any such
requirements of the Code.

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

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

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

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

         Nothing in this  Agreement  shall  require the Trustee to enter into an
amendment without receiving an Opinion of Counsel (which Opinion shall not be an
expense of the Trustee or the Trust Fund),  satisfactory to the Trustee that (i)
such amendment is permitted and is not prohibited by this Agreement and that all
requirements  for amending  this  Agreement  have been complied  with;  and (ii)
either (A) the amendment does not adversely  affect in any material  respect the
interests  of any  Certificateholder  or (B) the  conclusion  set  forth  in the
immediately  preceding clause (A) is not required to be reached pursuant to this
Section 11.1.

         SECTION 11.2 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  a majority  of the  Certificateholders  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 (by
facsimile or otherwise)  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 11.3 Governing Law.

         THIS  AGREEMENT  (OTHER THAN SECTION 2.1 HEREOF)  SHALL BE CONSTRUED IN
ACCORDANCE  WITH AND GOVERNED BY THE  SUBSTANTIVE  LAWS OF THE STATE OF NEW YORK
APPLICABLE TO  AGREEMENTS  MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND
THE   OBLIGATIONS,   RIGHTS  AND   REMEDIES  OF  THE  PARTIES   HERETO  AND  THE


                                     -101-

CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS. SECTION 2.1
OF THIS  AGREEMENT  SHALL BE  CONSTRUED IN  ACCORDANCE  WITH AND GOVERNED BY THE
SUBSTANTIVE  LAWS OF THE STATE OF DELAWARE  APPLICABLE TO AGREEMENTS MADE AND TO
BE PERFORMED IN THE STATE OF DELAWARE AND THE  OBLIGATIONS,  RIGHTS AND REMEDIES
OF THE PARTIES  HERETO AND THE  CERTIFICATEHOLDERS  UNDER SUCH SECTION  SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.

         SECTION 11.4 Intention of Parties.

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

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

         SECTION 11.5 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 2.3; and

                  (5)      The final payment to Certificateholders.

                           rating of the Master Servicer,  which notice shall be
                           made by  first-class  mail within two  Business  Days

         SECTION 11.6 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

         SECTION 11.8 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

Trustee  shall be entitled  to such  relief as can be given  either at law or in
equity.

         SECTION 11.9 Inspection and Audit Rights.

examine  all the books of  account,  records,  reports  and other  papers of the
Master  Servicer  relating to the  Mortgage  Loans,  to make copies and extracts
therefrom,  to cause such books to be audited by  independent  certified  public
accountants selected by the Depositor or the Trustee and to discuss its affairs,
finances  and  accounts  relating  to the  Mortgage  Loans  with  its  officers,
employees and independent  public  accountants (and by this provision the Master
Servicer hereby authorizes said accountants to discuss with such  representative
such affairs,  finances and accounts), all at such reasonable times and as often
as may be  reasonably  requested.  Any  out-of-pocket  expense  incident  to the
exercise by the  Depositor  or the Trustee of any right under this  Section 11.9
shall be borne by the party requesting such inspection;  all other such expenses
shall be borne by the Master Servicer or the related Subservicer.

               Mortgage Pass-Through Certificates Series 2005-AA10

              Representations and Warranties of the Master Servicer

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

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

                  (2) First Horizon has the full  corporate  power and authority
         to service each Mortgage Loan, and to execute, deliver and perform, and
         to enter  into and  consummate  the  transactions  contemplated  by the
         Pooling  and  Servicing  Agreement  and  has  duly  authorized  by  all
         necessary  corporate action on the part of First Horizon 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 First  Horizon,
         enforceable  against First Horizon 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

transfer  is made  pursuant to an  effective  registration  statement  under the
Securities Act and any applicable  state  securities  laws or is exempt from the
registration  requirements  under  said Act and such  laws.  In the event that a
transfer is to be made in reliance upon an exemption from the Securities Act and
such laws, in order to assure  compliance with the Securities Act and such laws,
the   Certificateholder    desiring   to   effect   such   transfer   and   such
Certificateholder's  prospective transferee shall each certify to the Trustee in
writing the facts surrounding the transfer. In the event that such a transfer is

of a transfer  pursuant  to Rule 144A of the  Securities  Act) to the Trustee an

Servicer or the  Depositor.  The Holder hereof  desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee and the Depositor against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.]

Trustee  shall have  received  either  (i) a  representation  [letter]  from the
transferee  of  such  Certificate,  acceptable  to and  in  form  and  substance
satisfactory  to the  Trustee,  to the  effect  that such  transferee  is not an
employee benefit plan or arrangement  subject to Section 406 of ERISA or Section
4975 of the  Code,  nor a  person  acting  on  behalf  of any such  plan,  which
representation  letter shall not be an expense of the Trustee,  the Depositor or

certificate   has  been   subject  to  an   ERISA-Qualifying   Underwriting,   a
representation  that the  purchaser is an insurance  company which is purchasing
such Certificates with funds contained in an "insurance company general account"

Exemption  95-60  ("PTCE  95-60"))  and that the  purchase  and  holding of such
Certificates  are covered under Sections I and III of PTCE 95-60 or (iii) in the
case of any  such  Certificate  presented  for  registration  in the  name of an
employee  benefit  plan  subject  to  ERISA  or  Section  4975 of the  Code  (or
comparable  provisions of any subsequent  enactments),  or a trustee of any such
plan or any  other  person  acting on behalf of any such  plan,  an  Opinion  of
Counsel  satisfactory  to the Trustee to the effect that the purchase or holding
of such Certificate will not result in prohibited transactions under Section 406
of ERISA and  Section  4975 of the Code and will not subject  the  Trustee,  the
Depositor  or the  Master  Servicer  to any  obligation  in  addition  to  those
undertaken in the Agreement, which Opinion of Counsel shall not be an expense of
the Trustee, the Depositor or the Master Servicer. [Such representation shall be
deemed to have been made to the  Trustee  by the  Transferee's  acceptance  of a
Certificate of this Class and by a beneficial owner's acceptance of its interest
in a Certificate of this Class.]  Notwithstanding  anything else to the contrary
herein, any purported transfer of a Certificate of this Class to or on behalf of

         Principal in respect of this  Certificate is  distributable  monthly as
set forth herein.  Accordingly,  the Certificate Balance at any time may be less
than the  Certificate  Balance as set forth herein.  This  Certificate  does not
evidence an  obligation  of, or an  interest  in, and is not  guaranteed  by the
Depositor,  the Master Servicer or the Trustee referred to below or any of their
respective  affiliates.  Neither this  Certificate  nor the  Mortgage  Loans are
guaranteed or insured by any governmental agency or instrumentality.

         This certifies that  _________________  is the registered  owner of the
Percentage  Interest  (obtained by dividing the denomination of this Certificate
by the  aggregate  Initial  Certificate  Balances  of the  denominations  of all
Certificates of the Class to which this Certificate  belongs) in certain monthly
distributions  with respect to a Trust Fund  consisting  of the  Mortgage  Loans
deposited by First Horizon Asset  Securities Inc. (the  "Depositor").  The Trust
Fund was created  pursuant to a Pooling and Servicing  Agreement dated as of the
Cut-off  Date  specified  above (the  "Agreement")  among the  Depositor,  First
Horizon Home Loan Corporation,  as master servicer (the "Master Servicer"),  and
The Bank of New York,  as trustee  (the  "Trustee").  To the extent not  defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

         Any  distribution of the proceeds of any remaining  assets of the Trust
Fund  will be made only upon  presentment  and  surrender  of this  Class  I-A-R
Certificate at the Corporate Trust Office or the office or agency  maintained by
the Trustee in New York, New York.  This Class I-A-R  Certificate  represents an
ownership in the RL Interest and RU Interest, as defined in the Agreement.

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

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

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

                        [Form of Reverse of Certificates]

          First Horizon Alternative Mortgage Securities Trust 2005-AA10
                       Mortgage Pass-Through Certificates

         This  Certificate  is one of a duly  authorized  issue of  Certificates
designated as First Horizon  Alternative  Mortgage  Securities  Trust  2005-AA10
Mortgage Pass-Through  Certificates,  of the Series specified on the face hereof
(herein collectively called the  "Certificates"),  and representing a beneficial
ownership interest in the Trust Fund created by the Agreement.

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

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

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

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

         The Agreement permits,  with certain  exceptions therein provided,  the
amendment  thereof and the  modification  of the rights and  obligations  of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the  Depositor,  the Master  Servicer and the Trustee with the consent of the
Holders of  Certificates  affected by such  amendment  evidencing  the requisite
Percentage  Interest,  as provided  in the  Agreement.  Any such  consent by the
Holder of this  Certificate  shall be conclusive  and binding on such Holder and
upon all future Holders of this  Certificate and of any Certificate  issued upon
the  transfer  hereof or in exchange  therefor or in lieu hereof  whether or not


                                      D-1
<PAGE>

notation  of such  consent is made upon this  Certificate.  The  Agreement  also
permits the amendment  thereof,  in certain limited  circumstances,  without the
consent of the Holders of any of the Certificates.

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

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

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

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

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

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

STATE OF      )
              ) ss.:
COUNTY OF     )

         The undersigned, being first duly sworn, deposes and says as follows:

         1. The undersigned is an officer of __________, the proposed Transferee
of an Ownership Interest in a Class I-A-R Certificate (the "Certificate") issued
pursuant to the Pooling and Servicing Agreement, (the "Agreement"),  relating to
the  above-referenced  Series, by and among First Horizon Asset Securities Inc.,
as depositor (the "Depositor"),  First Horizon Home Loan Corporation,  as master
servicer, and The Bank of New York, as trustee.  Capitalized terms used, but not
defined herein or in Exhibit 1 hereto,  shall have the meanings ascribed to such
terms in the Agreement.  The  Transferee has authorized the  undersigned to make
this affidavit on behalf of the Transferee.

         2. The  Transferee  is, as of the date  hereof,  and will be, as of the
date of the Transfer,  a Permitted  Transferee.  The Transferee is acquiring its
Ownership  Interest in the Certificate either (i) for its own account or (ii) as
nominee,  trustee  or agent  for  another  Person  and has  attached  hereto  an
affidavit from such Person in substantially the same form as this affidavit. The
Transferee has no knowledge that any such affidavit is false.

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

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

<PAGE>

         5. The  Transferee has reviewed the provisions of Section 5.2(c) of the
Agreement  (attached hereto as Exhibit 2 and  incorporated  herein by reference)
and  understands  the legal  consequences  of the  acquisition  of an  Ownership
Interest in the Certificate including,  without limitation,  the restrictions on
subsequent  Transfers  and the  provisions  regarding  voiding the  Transfer and
mandatory sales. The Transferee  expressly agrees to be bound by and to abide by
the provisions of Section 5.2(c) of the Agreement and the restrictions  noted on
the face of the  Certificate.  The  Transferee  understands  and agrees that any
breach of any of the  representations  included herein shall render the Transfer
to the Transferee contemplated hereby null and void.

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

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

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

         9. The  Transferee  is either a U.S.  Person as defined in Code Section
7701(a)(30) or the Transferee has furnished the Transferor a properly  completed
Internal Revenue Service Form W-8ECI.

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

         11. The  Transferee  is not an  employee  benefit  plan or  arrangement
subject to Section 406 of ERISA or a plan or arrangement subject to Section 4975
of the Code, nor a person acting on behalf of any such plan or arrangement,  nor
using the assets of any such plan or arrangement to effect such transfer.

         12. The Transferee has historically paid its debts as they came due and
the  Transferee  will  continue to pay its debts as they come due in the future;
the  Transferee  understands  that,  as  the  holder  of  the  Certificate,  the
Transferee may incur tax  liabilities  in excess of any cash flows  generated by
the Certificate and the Transferee  intends to pay taxes associated with holding
the Certificate as they become due.

         13.  The  Transferee  is a  domestic  corporation  taxable as a regular
corporation  for U.S.  federal  income  tax  purposes  (a  "taxable  domestic  C
corporation") and is not a real estate investment  trust,  regulated  investment
company or REMIC.  The Transferee  will not cause income from the Certificate to
be attributable,  for U.S. federal income tax purposes, to a non-U.S.  permanent


                                      H-2

establishment  or fixed base  (within  the meaning of an  applicable  income tax
treaty) of the Transferee or another U.S. taxpayer. At the time of the Transfer,
and at the close of each of the Transferee's two fiscal years preceding the year
of the Transfer,  the Transferee's gross assets for financial reporting purposes
exceeded $10 million (together,  the "Asset  Requirements"),  and the Transferee
hereby covenants that any subsequent  Transfer of its Ownership  Interest in the
Certificate  will be to another taxable,  domestic C corporation  satisfying the
Asset Requirements

         IN WITNESS  WHEREOF,  the Transferee  has caused this  instrument to be
executed on its behalf,  pursuant to authority of its Board of Directors, by its
duly  authorized  officer and its corporate  seal to be hereunto  affixed,  duly
attested, this ___ day of _________, 20__.

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

any State or political  subdivision thereof, or any agency or instrumentality of
any of the foregoing, (ii) a foreign government,  International  Organization or
any agency or instrumentality of either of the foregoing,  (iii) an organization
(except  certain  farmers'  cooperatives  described  in section 521 of the Code)

any  Certificate,  (iv) rural electric and telephone  cooperatives  described in

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

         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 5.2(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  5.2(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  5.2(b) and this Section  5.2(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 in the case
         of a Residual Certificate which is also a Private  Certificate,  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  5.2(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 or the Master
Servicer, to the effect that the elimination of such restrictions will not cause
any REMIC  created  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.

bank or  savings  and loan is  provided  above,  the Buyer  agrees  that it will
furnish to such parties updated annual financial  statements promptly after they
become available.
