                     presence of the MIN of the Mortgage Loans and either
                     language indicating that the Mortgage Loan is a MOM Loan if
                     the Mortgage Loan is a MOM Loan or if the Mortgage Loan was
                     not a MOM Loan at origination, the original Mortgage and
                     the assignment thereof to MERS, with evidence of recording
                     indicated thereon, or a copy of the Mortgage certified by

              (iii)  in the case of a Mortgage Loan that is not a MERS Mortgage
                     Loan, a duly executed assignment of the Mortgage in blank
                     (which may be included in a blanket assignment or
                     assignments), together with, except as provided below, all
                     interim recorded assignments of such mortgage (each such
                     assignment, when duly and validly completed, to be in
                     recordable form and sufficient to effect the assignment of
                     and transfer to the assignee thereof, under the Mortgage to
                     which the assignment relates); provided that, if the
                     related Mortgage has not been returned from the applicable
                     public recording office, such assignment of the Mortgage

                     office;

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

              (v)    either the original or duplicate original title policy
                     (including all riders thereto) with respect to the related
                     Mortgaged Property, if available, provided that the title
                     policy (including all riders thereto) will be delivered as
                     soon as it becomes available, and if the title policy is
                     not available, and to the extent required pursuant to the
                     second paragraph below or otherwise in connection with the
                     rating of the Certificates, 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, 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

                                       42
<PAGE>

                     (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
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. 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.

                                       43
<PAGE>

         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 2005-2, 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.

         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.

         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 Final Certification in the form annexed hereto as Exhibit G, with any
applicable exceptions noted thereon.

                                       45
<PAGE>

         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 Final
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
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

         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 the MLPA, and which refers to, among other
representations and warranties in the MLPA, 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 the MLPA, are required to conform to, among other
representations and warranties, a representation and warranty of the Seller set
forth in the MLPA 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 the MLPA
              that materially and adversely affects the interests of the
              Certificateholders in any Mortgage Loan, the party discovering
              such breach shall give prompt notice thereof to the other parties.
              The Seller hereby covenants that within 90 days of the earlier of
              its discovery or its receipt of written notice from any party of a
              breach of any representation or warranty made pursuant to Schedule
              B to the MLPA 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.

                                       47
<PAGE>

         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
the MLPA 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
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.

                                       48
<PAGE>

         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 the MLPA 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.

                                       49
<PAGE>

         (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 the
              MLPA 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 Middle REMIC.

         The assets of the Middle REMIC shall be as set forth in the definition
thereof. Each interest identified in the second table below by a designation
beginning with "M" shall be a "regular interest" in the Middle REMIC and a

and shall be held by the Trustee as assets of the Upper REMIC.

                                       50

Lower REMIC Interests shall only correspond to the portion supported by Pool I).
Lower REMIC Interest L-I-PO shall be a Corresponding Class to M-I-PO. 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 Middle REMIC
Interests: M-II-A-1, M-II-A-2, M-B-1, M-B-2, M-B-3, M-B-4, M-B-5 and M-B-6
(provided that with respect to M-B-1, M-B-2, M-B-3, M-B-4, M-B-5 and M-B-6, such
Lower REMIC Interests shall only correspond to the portion supported by Pool

<PAGE>

         "L1 Interests" refers to the L-I-A-1 Lower REMIC Interest, L-II-A-1
Lower REMIC Interest and the L-III-A-1 Lower REMIC Interests. "L2 Interests"
refers to the L-I-A-2 Lower REMIC Interest, L-II-A-2 Lower REMIC Interest and
the L-III-A-2 Lower REMIC Interest. "LZZZ Interests" refers to L-I-A-ZZZ Lower
REMIC Interest, L-II-A-ZZZ Lower REMIC Interest and L-III-A-ZZZ Lower REMIC
Interest. "LPO Interests" refer to the L-I-PO Lower REMIC Interest and the
L-II-PO 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 (i)
the initial principal balances of the L1 Interests and L2 Interests
corresponding to such Mortgage Pool, and (ii) the portion of the LPO Interest
attributable to the Discount Mortgage Loans in the Mortgage Pool corresponding
to such LZZZ Interest.

         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
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 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 Designated Mortgage Pool Rate (as
defined below) lower than the Designated Mortgage Pool 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 Designated Mortgage Pool Rate higher than the Mortgage Pool from which
the payment was reallocated it shall reimburse the Middle REMIC for prior
Realized Losses.

The Class L-I-PO Interest shall be entitled to receive the Class PO Principal
Distribution Amount for Pool I.

The Class L-II-PO Interest shall be entitled to receive the Class PO Principal
Distribution Amount for Pool II.

(1) The Middle REMIC Interest Rate for the Middle REMIC Interest M-B-1, Middle
REMIC Interest M-B-2, Middle REMIC Interest M-B-3, Middle REMIC Interest M-B-4,
Middle REMIC Interest M-B-5, Middle REMIC Interest M-B-6 shall equal the
Calculation Rate as defined in this Section 2.7. The Pass-Through Rate on each
Class of Subordinated Certificates is variable and will be equal to the weighted
average of the Middle REMIC Interest Rates on Middle REMIC Interest M-B-1,
Middle REMIC Interest M-B-2, Middle REMIC Interest M-B-3, Middle REMIC Interest
M-B-4, Middle REMIC Interest M-B-5, Middle REMIC Interest M-B-6, weighted on the
basis of the principal balance of each such Middle REMIC Interest. Any excess
cashflow shall be payable to the RM Interest.

         On each Distribution Date Available Funds shall be distributed with
respect to the Middle REMIC Interests in a manner such that:

                                       54
<PAGE>

         (a)  interest accrued, if any, on each Middle REMIC Interest is
              distributed with respect to each such Middle REMIC Interest in the
              same manner that Accrued Certificate Interest is distributed with
              respect to the Corresponding Class or Classes of Certificates
              pursuant to Section 4.2; and

         (b)  principal is distributed (and Realized Losses shall be allocated)
              with respect to each such Middle REMIC Interest in the same manner
              that principal is distributed (and Realized Losses is allocated)
              with respect to the Corresponding Classes or Classes of
              Certificate pursuant to Section 4.2 and Section 4.4.

         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.

                                  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
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.

                                       55
<PAGE>

         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 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.

                                       57
<PAGE>

         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 three 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, any Prepayment Interest Excess and, for so
                     long as First Horizon is the Master Servicer, any Retained
                     Yield;

              (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,

         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 three 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:

              (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. 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 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.

                   SECTION 3.7 Access to Certain Documentation and Information
         Regarding the Mortgage Loans.

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

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

                   SECTION 3.8 Permitted Withdrawals from the Certificate
         Account and Distribution Account.

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

              (i)    to the extent not previously retained by the Master
                     Servicer, to pay to First Horizon the Retained Yield and to

                     compensation to which it is entitled pursuant to Section
                     3.14, and earnings on or investment income with respect to
                     funds in or credited to the Certificate Account as
                     additional master servicing compensation;

              (ii)   to the extent not previously retained by the Master
                     Servicer, to reimburse the Master Servicer for unreimbursed
                     Advances made by it in respect of the related Mortgage
                     Pool, such right of reimbursement pursuant to this
                     subclause (ii) being limited to amounts received on the
                     Mortgage Loan(s) in respect of which any such Advance was
                     made;

              (iii)  to reimburse the Master Servicer for any Nonrecoverable

              (iv)   to reimburse the Master Servicer for Insured Expenses from

              (v)    to reimburse the Master Servicer for (a) unreimbursed
                     Servicing Advances in respect of the related Mortgage Pool,
                     the Master Servicer's right to reimbursement pursuant to
                     this clause (a) with respect to any Mortgage Loan being
                     limited to amounts received on such Mortgage Loan(s) which
                     represent late recoveries of the payments for which such
                     advances were made pursuant to Section 3.1 or Section 3.6
                     and (b) for unpaid Master Servicing Fees as provided in
                     Section 3.11 hereof;

                                       62

              (vi)   to pay to the Seller or Master Servicer, as applicable,
                     with respect to each Mortgage Loan in respect of the
                     related Mortgage Pool or property acquired in respect
                     thereof that has been purchased pursuant to Section 2.2,
                     2.3 or 3.11, all amounts received thereon after the date of
                     such purchase;

              (vii)  to reimburse the Seller, the Master Servicer or the

              (ix)   on or prior to the Distribution Account Deposit Date, to
                     withdraw an amount equal to the related Available Funds and

                     amount to the Trustee for deposit in the Distribution

                     hereof.

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

                  The Master Servicer shall distribute the Retained Yield, if
         any, to First Horizon on each Distribution Account Deposit Date during
         the term of this Agreement.

         (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

              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 Account for the following
              purposes:

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

                                       63
<PAGE>

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

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

              (iv)   to clear and terminate the Distribution Account upon
                     termination of the Agreement pursuant to Section 9.1
                     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.

                                       64

         (b)  In the event that the Master Servicer shall obtain and maintain a
              blanket policy insuring against hazard losses on all of the
              Mortgage Loans, it shall conclusively be deemed to have satisfied
              its obligations as set forth in the first sentence of this
              Section, it being understood and agreed that such policy may
              contain a deductible clause on terms substantially equivalent to
              those commercially available and maintained by comparable
              servicers. If such policy contains a deductible clause, the Master
              Servicer shall, in the event that there shall not have been
              maintained on the related Mortgaged Property a policy complying
              with the first sentence of this Section, and there shall have been
              a loss that would have been covered by such policy, deposit in the
              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.

                                       65
<PAGE>

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

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

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

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

         With respect to any REO Property, the deed or certificate of sale shall
be taken in the name of the 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 and may, incident to its
conservation and protection of the interests of the Certificateholders, rent the
same, or any part thereof, as the Master Servicer deems to be in the best
interest of the Certificateholders for the period prior to the sale of such REO
Property. The Master Servicer shall 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.

                                       67
<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.

                                       68
<PAGE>

         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
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.

                                       69
<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.

                                       70
<PAGE>

         Additional servicing compensation in the form of (i) Retained Yield,
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; provided that in the
event the Master Servicer is terminated pursuant to Section 7.1, the Retained
Yield shall be payable to First Horizon Home Loan Corporation in its individual
capacity and shall not be payable to the Trustee or any successor to the Master
Servicer. 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
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

                  this subsection (g) shall not reduce the Class Certificate
                  Balances of the Class I-A-R Certificates.

         (h)      On and after the Cross-Over Date, the amount distributable to
                  the Senior Certificates of the related Certificate Group
                  pursuant to Section 4.2(a)(iii) for the related Distribution
                  Date (other than the related Class PO Certificates) shall be
                  allocated among the related Classes of Senior Certificates,
                  pro rata, on the basis of their respective Class Certificate
                  Balances immediately prior to such Distribution Date,
                  regardless of the priorities and amounts set forth in Sections
                  4.2(c), (d) and (e).

         (i)      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
                  Optimal Principal Amount remain undistributed on such
                  Distribution Date after all amounts otherwise distributable on
                  such date pursuant to clauses (v) 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)(iii).

         (j)      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


                                       77
<PAGE>

                  outstanding Classes of Certificates entitled thereto in
                  accordance with the preceding sentence, subject to the
                  remainder of this subsection (i). 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 (i) with respect to the Principal
         Only Certificates, based on the applicable Class I-A-PO Percentage and
         Class II-A-PO Percentage of the principal portion of the Realized Loss
         previously allocated thereto with respect to such Mortgage Loan (or all
         Mortgage Loans for purposes of the next to last sentence of the
         preceding paragraph), and (ii) with respect to any other Class of
         Certificates, based on its pro rata share (in proportion to the Class
         Certificate Balances thereof with respect to such Distribution Date) of
         the applicable Non-Class I-A-PO Percentage or Non-Class II-A-PO
         Percentage of the principal portion of any such Realized Loss
         previously allocated with respect to such Mortgage Loan (or Loans);
         provided however, that (i) the share of an Unanticipated Recovery
         allocable to a Principal Only Certificate with respect to any Mortgage
         Loan (or Loans) shall be reduced by the applicable Class I-A-PO
         Percentage or Class II-A-PO Percentage of the aggregate amount
         previously distributed to such Class in respect of such Mortgage Loan
         (or Loans) and (ii) the amount by which the distributions to the
         Principal Only Certificates have been so reduced shall be distributed
         to the Classes of Certificates described in clause (ii) of the
         preceding paragraph in the same proportion as described in such clause
         (ii). For purposes of the preceding sentence, any Class PO Deferred
         Amount distributable to a Principal Only Certificate on previous
         Distribution Dates shall be deemed to have been allocated in respect of
         the Mortgage Loans as to which the applicable Class I-A-PO Percentage
         and Class II-A-PO Percentage of the principal portion of Realized
         Losses has previously been allocated to such Class on a pro rata basis
         (based on the amount of Realized Losses allocated).

         (k)      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 (other than the Principal Only
                  Certificates) in accordance with the priorities set forth in
                  Section 4.2(a)(iii), until the total Class Certificate Balance
                  of such Senior Certificates equals the Pool Principal Balance
                  of the related Mortgage Pool (such distribution, an
                  "Undercollateralization Distribution"). If the Senior
                  Certificates of a Certificate Group (other than the Principal
                  Only Certificates) 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 other Mortgage Pool (or


                                       78
<PAGE>

                  Pools) remaining after all required amounts for that
                  Distribution Date have been distributed to the Senior
                  Certificates of the other Certificate Group (or Groups) (other
                  than the Principal Only Certificates). In addition, the amount
                  of any unpaid Accrued Certificate Interest with respect to an
                  Undercollateralized Group on any Distribution Date (including
                  any Accrued Certificate Interest for the related Distribution
                  Date) will be distributed to the Senior Certificates of the
                  Undercollateralized Group (other than the Principal Only
                  Certificates) 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(k), no distribution of
                  principal will be made to any Class of Subordinated
                  Certificates until each 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. If more than one Certificate Group
                  on any Distribution Date is required to make an
                  Undercollateralization Distribution to an Undercollateralized
                  Group, the payment of such Undercollateralization
                  Distributions shall be allocated among such Certificate
                  Groups, pro rata, on the basis of the aggregate Class
                  Certificate Balance of the related Senior Certificates.

                  In addition, if on any Distribution Date the total Class
         Certificate Balance of the Senior Certificates of one or more
         Certificate Groups (other than the Principal Only Certificates) (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 (or Groups) (other
         than the Principal Only Certificates) unless (a) the weighted average
         of the Subordinated Percentages for the Mortgage Pools, weighted on the
         basis of the Stated Principal Balance of the Mortgage Loans in the
         related Mortgage Pool (other than the Principal Only Certificates), is
         at least two times the weighted average of the initial Subordinate
         Percentage for the Mortgage Pools (calculated on such basis) and (b)
         the aggregate Stated Principal Balance of all of the Mortgage Loans in
         the Mortgage Pools delinquent 60 days or more (including for this
         purpose any such 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%. All distributions described above will be made in
         accordance with the priorities set forth in Sections 4.2(a)(iii).

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


                                       79
<PAGE>

                  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
                  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)      the applicable Class I-A-PO Percentage or Class
                           II-A-PO Percentage of the principal portion of any
                           such Realized Loss on a Discount Mortgage Loan in
                           Pool I or Pool II shall be allocated to the Class
                           I-A-PO Percentage or Class II-A-PO Percentage,
                           respective until the Class Certificate Balance
                           thereof has been reduced to zero; and

                  (ii)     the principal portion of any such Realized Loss (or
                           the applicable Class I-A-PO Percentage or Class
                           II-A-PO Percentage thereof) shall be allocated in the
                           following order of priority:

                           first, to the Class B-6 Certificates until the Class
                           Certificate Balance thereof has been reduced to zero;

                           second, to the Class B-5 Certificates until the Class
                           Certificate Balance thereof has been reduced to zero;

                           third, to the Class B-4 Certificates until the Class
                           Certificate Balance thereof has been reduced to zero;

                           fourth, to the Class B-3 Certificates until the Class
                           Certificate Balance thereof has been reduced to zero;

                           fifth, to the Class B-2 Certificates until the Class
                           Certificate Balance thereof has been reduced to zero;

                           sixth, to the Class B-1 Certificates until the Class
                           Certificate Balance thereof has been reduced to zero;
                           and

                           seventh, to the Classes of Senior Certificates of the
                           related Certificate Group (other than the Principal
                           Only Certificates), pro rata, in accordance with
                           their Class Certificate Balances.

         (c)      Commencing on the Cross-over Date, the applicable Non-PO
                  Percentage of the principal portion of any Realized Loss for a
                  Mortgage Pool will be allocated among the outstanding classes
                  of Senior Certificates of the related Certificate Group
                  entitled to principal distributions (other than the Class
                  II-A-1 Certificates, as long as the Class II-A-2 Certificates
                  are outstanding, and the Class PO Certificates) pro rata based
                  upon their Class Certificate Balances within such Certificate
                  Group.

         (d)      After the Cross-over Date, the principal portion of Realized
                  Losses (other than Excess Losses) on the Mortgage Loans
                  allocable to the Class II-A-1 Certificates will instead be
                  borne first by the Class II-A-2 Certificates until its Class
                  Certificate Balance is reduced to zero (in addition to other
                  Realized Losses allocated to the Class II-A-2 Certificates),
                  and not by the Class II-A-1 Certificates, for so long as the
                  Class Certificate Balance of the Class II-A-2 Certificates is
                  greater than zero

         (e)      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).

         (f)      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
                  Class Certificate Balances. Any allocation of Realized Losses
                  pursuant to this paragraph (f) shall be accomplished by
                  reducing the Class Certificate Balances of the related
                  Certificates on the related Distribution Date in accordance
                  with Section 4.4(g).

         (g)      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.

         (h)      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.

         (i)      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").

         (c)      On or before the fifth Business Day following the end of each

                  substantially the form set forth as Schedule III hereto.

SECTION 4.8 [RESERVED]

SECTION 4.9 Determination of Pass-Through Rates for LIBOR Certificates.

         (a)      On each Interest Determination Date so long as any LIBOR
                  Certificates are outstanding, the Trustee will determine LIBOR
                  on the basis of the British Bankers' Association ("BBA")
                  "Interest Settlement Rate" for one-month deposits in U.S.
                  dollars as found on Telerate page 3750 as of 11:00 a.m. London
                  time on each LIBOR Determination Date. "Telerate Page 3750"
                  means the display page currently so designated on the Bridge
                  Telerate Service (formerly the Dow Jones Markets) (or such
                  other page as may replace that page on that service for the
                  purpose of displaying comparable rates or prices.)

         (b)      If LIBOR cannot be determined as provided in paragraph (a) of
                  this Section 4.9, the Trustee shall either (i) request each
                  Reference Bank inform the Trustee of the quotation offered by
                  such Reference Bank's principal London office for making
                  one-month United States dollar deposits in leading banks in
                  the London interbank market, as of 11:00 a.m. (London time) on
                  such Interest Determination Date or (ii) in lieu of making any
                  such request, rely on such Reference Bank quotations that
                  appear at such time on the Reuters Screen LIBO Page (as
                  defined in the International Swap Dealers Association Inc.
                  Code of Standard Wording, Assumptions and Provisions for
                  Swaps, 1986 Edition), to the extent available. With respect to
                  this Section 4.9, LIBOR for the next Interest Accrual Period
                  will be established by the Trustee on each Interest
                  Determination Date as follows:

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

                  (ii)     If on any Interest Determination Date only one or
                           none of the Reference Banks provides such offered
                           quotations, LIBOR for the next Interest Accrual
                           Period shall be whichever is the higher of (i) LIBOR
                           as determined on the previous Interest Determination
                           Date or (ii) the Reserve Interest Rate. The "Reserve
                           Interest Rate" shall be the rate per annum which the
                           Trustee determines to be either (i) the arithmetic
                           mean (rounded upwards if necessary to the nearest
                           whole multiple of 1/32%) of the one-month United
                           States dollar lending rates that New York City banks


                                       85
<PAGE>

                           selected by the Trustee are quoting, on the relevant
                           Interest Determination Date, to the principal London
                           offices of at least two of the Reference Banks to
                           which such quotations are, in the opinion of the
                           Trustee, being so made, or (ii) in the event that the
                           Trustee can determine no such arithmetic mean, the
                           lowest one-month United States dollar lending rate
                           which New York City banks selected by the Trustee are
                           quoting on such Interest Determination Date to
                           leading European banks.

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

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

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

         In determining LIBOR, any Pass-Through Rate for the LIBOR Certificates,
any Interest Settlement Rate, or any Reserve Interest Rate, the Trustee may
conclusively rely and shall be protected in relying upon the offered quotations
(whether written, oral or on the Dow Jones Markets) from the BBA designated
banks, the Reference Banks or the New York City banks as to LIBOR, the Interest
Settlement Rate or the Reserve Interest Rate, as appropriate, in effect from
time to time. The Trustee shall not have any liability or responsibility to any
Person for (i) the Trustee's selection of New York City banks for purposes of
determining any Reserve Interest Rate or (ii) its inability, following a
good-faith reasonable effort, to obtain such quotations from, the BBA designated
banks, the Reference Banks or the New York City banks or to determine such
arithmetic mean, all as provided for in this Section 4.9.

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

SECTION 5.1 The Certificates.

         The Certificates shall be substantially in the forms attached hereto as

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

         Subject to Section 9.2 hereof respecting the final distribution on the

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.

         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


                                       87
<PAGE>

                  Trustee shall execute and deliver, in the name of the
                  designated transferee or transferees, one or more new
                  Certificates of the same Class and aggregate Percentage
                  Interest.

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

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

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

         (b)      No transfer of a Private Certificate shall be made unless such
                  transfer is made pursuant to an effective registration
                  statement under the Securities Act and any applicable state
                  securities laws or is exempt from the registration
                  requirements under said Act and such state securities laws. In
                  the event that a transfer is to be made in reliance upon an
                  exemption from the Securities Act and such laws, in order to
                  assure compliance with the Securities Act and such laws, the
                  Certificateholder desiring to effect such transfer and such
                  Certificateholder's prospective transferee shall each certify
                  to the Trustee in writing the facts surrounding the transfer
                  in substantially the forms set forth in Exhibit 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. 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


                                       88
<PAGE>

                  sentence. Each Holder of a Private Certificate desiring to
                  effect such transfer shall, and does hereby agree to,
                  indemnify the Trustee and the Depositor, the Seller and the
                  Master Servicer against any liability that may result if the
                  transfer is not so exempt or is not made in accordance with
                  such federal and state laws.

                  No transfer of a Principal Only Certificate shall be made
         unless the transferee of such Certificate (i) 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 or
         arrangement, nor using the assets of any such plan or arrangement to
         effect such transfer, (ii) such Principal Only Certificate has been
         subject to an ERISA-Qualified Underwriting, or (iii) in the case of any
         such Principal Only Certificate not satisfying clause (ii) and
         presented for registration in the name of an employee benefit plan
         subject to ERISA, or a plan or arrangement subject to Section 4975 of
         the Code (or comparable provisions of any subsequent enactments), or a
         trustee of any such plan or any other person acting on behalf of any
         such plan or arrangement, or using such plan's or arrangement's assets,
         an Opinion of Counsel satisfactory to the Trustee, which Opinion of
         Counsel shall not be an expense of either the Trustee or the Trust
         Fund, addressed to the Trustee to the effect that the purchase or
         holding of such Principal Only 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.

                  No transfer of an ERISA-Restricted 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


                                       89
<PAGE>

         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.

         (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


                                       90
<PAGE>

                           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


                                       92
<PAGE>

         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


                                       94
<PAGE>

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 a successor master servicer shall
have assumed the Master Servicer's responsibilities, duties, liabilities and
obligations hereunder.

                                  ARTICLE VII
                                     DEFAULT

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


                                       95
<PAGE>

         (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


                                       96
<PAGE>

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


                                       97
<PAGE>

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.

         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
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.

         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

                  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 the obligations of
                  the Master Servicer under this 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

                  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.

         Except as otherwise provided in Section 8.1:

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

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

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

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


                                      101
<PAGE>

         (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

         (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,


                                      102
<PAGE>

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

                                      103
<PAGE>

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.

         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.


                                      104
<PAGE>

         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
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


                                      105
<PAGE>

                           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


                                      106
<PAGE>

         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.

                                   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 Pool Principal Balance for all of the
Mortgage Pools, at the time of any such repurchase, aggregating less than ten
percent (10%) of the aggregate Cut-off Date Principal Balance of the Mortgage
Loans.

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.


                                      109
<PAGE>

         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
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


                                      111
<PAGE>

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 11.4 Intention of Parties.

         It is the express intent of the parties hereto that the conveyance of

any security interest granted or assigned to the Trustee for the benefit of the
Certificateholders.

                Mortgage Pass-Through Certificates Series 2005-2

              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
         Agreement by First Horizon, the servicing of the Mortgage Loans by
         First Horizon under the Pooling and Servicing Agreement, the
         consummation of any other of the transactions contemplated by the
         Pooling and Servicing Agreement, and the fulfillment of or compliance
         with the terms thereof are in the ordinary course of business of First
         Horizon and will not (A) result in a material breach of any term or
         provision of the charter or by-laws of First Horizon or (B) materially
         conflict with, result in a material breach, violation or acceleration
         of, or result in a material default under, the terms of any other


                                      II-1
<PAGE>

         material agreement or instrument to which First Horizon is a party or
         by which it may be bound, or (C) constitute a material violation of any
         statute, order or regulation applicable to First Horizon of any court,
         regulatory body, administrative agency or governmental body having
         jurisdiction over First Horizon; and First Horizon is not in breach or
         violation of any material indenture or other material agreement or
         instrument, or in violation of any statute, order or regulation of any
         court, regulatory body, administrative agency or governmental body
         having jurisdiction over it which breach or violation may materially
         impair First Horizon's ability to perform or meet any of its
         obligations under the Pooling and Servicing Agreement.

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

                  (5) First Horizon is a member of MERS in good standing, and
         will comply in all material respects with the rules and procedures of
         MERS in connection with the servicing of the MERS Mortgage Loans for as
         along as such Mortgage Loans are registered with MERS.

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

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

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

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

limited to the restrictions that (i) each person holding or acquiring any

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.

                        [Form of Reverse of Certificates]

                First Horizon Mortgage Pass-Through Trust 2005-2
                       Mortgage Pass-Through Certificates

      This Certificate is one of a duly authorized issue of Certificates
designated as First Horizon Mortgage Pass-Through Trust 2005-2 Mortgage
Pass-Through Certificates, of the Series specified on the face hereof (herein
collectively called the "Certificates"), and representing a beneficial ownership
interest in the Trust Fund created by the Agreement.

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

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

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

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

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

                                       D-1
<PAGE>

      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 Pool Principal Balance is less than
10% of the aggregate Cut-off Date Pool Principal Balances of Pool I, Pool II and
Pool III combined, 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.)

                                      H-1
<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 represent one or more
interests in 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
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

                                      H-2

                               Certain Definitions

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

      "Permitted Transferee": Any Person other than (i) the United States, any
State or political subdivision thereof, or any agency or instrumentality of any
of the foregoing, (ii) a foreign government, International Organization or any
agency or instrumentality of either of the foregoing, (iii) an organization
(except certain farmers' cooperatives described in section 521 of the Code)
which is exempt from tax imposed by Chapter 1 of the Code (including the tax
imposed by section 511 of the Code on unrelated business taxable income) on any
excess inclusions (as defined in section 860E(c)(l) of the Code) with respect to
any Certificate, (iv) rural electric and telephone cooperatives described in
section 1381(a)(2)(C) of the Code, (v) an "electing large partnership" as
defined in section 775 of the Code, (vi) a Person that is not (a) a citizen or
resident of the United States, (b) a corporation, partnership, or other entity
created or organized in or under the laws of the United States, any state
thereof or the District of Columbia, (c) an estate whose income from sources
without the United States is includible in gross income for United States
federal income tax purposes regardless of its connection with the conduct of a
trade or business within the United States or (d) a trust if a court within the
United States is able to exercise primary supervision over the administration of
the trust and one or more United States persons have the authority to control
all substantial decisions of the trust, unless such Person has furnished the
transferor and the Trustee with a duly completed Internal Revenue Service Form
W-8ECI or any applicable successor form, and (vii) any other Person so
designated by the Depositor based upon an Opinion of Counsel that the Transfer
of an Ownership Interest in a Certificate to such Person may cause any REMIC
created pursuant to the Agreement to fail to qualify as a REMIC at any time that
the Certificates (as defined in the Agreement) are outstanding; provided,
however, that if a person is classified as a partnership or a disregarded entity
under the Code, such person shall only be a Permitted Transferee if all of its
beneficial owners are described in subclauses (a), (b), (c) or (d) of clause
(vi) and the governing documents of such person prohibits a transfer of any
interest in such person to any person described in clause (vi). The terms
"United States," "State" and "International Organization" shall have the
meanings set forth in section 7701 of the Code or successor provisions. A
corporation will not be treated as an instrumentality of the United States or of
any State or political subdivision thereof for these purposes if all of its
activities are subject to tax and, with the exception of the Federal Home Loan
Mortgage Corporation, a majority of its board of directors is not selected by
such government unit.

      "Person": Any individual, corporation, partnership, joint venture,
association, bank, joint-stock company, trust (including any beneficiary
thereof), unincorporated organization or government or any agency or political
subdivision thereof.

      "Transfer": Any direct or indirect transfer or sale of any Ownership
Interest in a Certificate, including the acquisition of a Certificate by the
Depositor.

<PAGE>

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

                                                          EXHIBIT 2 to EXHIBIT H

                         Section 5.2(c) of the Agreement

      (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.

                                      H-6
<PAGE>

            (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.
