      The Depositor is the owner of the Trust Fund that is hereby conveyed to
the Trustee in return for the Certificates. The Trust Fund for federal income
tax purposes will consist of two separate REMICs. The Certificates will

date" for federal income tax purposes of all REMIC regular interests created
hereby will be the Latest Possible Maturity Date.

      The following table sets forth characteristics of the Certificates,
together with the minimum denominations and integral multiples in excess thereof

<PAGE>

      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; provided further, however, that the
Depositor shall not be required to deliver an original or duplicate lender's
title policy (together with all riders thereto) if the Depositor delivers an
Alternative Title Product in lieu thereof. Notwithstanding the preceding, in
connection with any Mortgage Loan for which either the original or duplicate
original title policy has not been delivered to the Trust, if at any time during
the term of this Agreement the parent company of the Seller does not have a long
term senior debt rating of A- or higher from S&P and A- or higher from Fitch (if
rated by Fitch), then the Depositor shall within 30 days deliver or cause to be
delivered to the Trustee or the Custodian on its behalf (if it has not
previously done so) a written commitment or interim binder or preliminary report
of the title issued by the title insurance or escrow company with respect to the
Mortgaged Property.


                                       37
<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
2005-3, 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.

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.

      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


                                       39
<PAGE>

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 constituting the
Mortgage File as come into the possession of the Master Servicer from time to
time.

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

      The mortgage loans permitted by the terms of this Agreement to be included
in the Trust Fund are limited to (i) the Mortgage Loans (which the Depositor
acquired pursuant to 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.


                                       41
<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.

      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.


                                       42
<PAGE>

      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.


                                       43
<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 Upper REMIC.

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

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

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

      (a)    interest accrued, if any, on each Lower REMIC Interest is
            distributed with respect to each such Lower 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 Lower 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.


                                       46
<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.

      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.


                                        48
<PAGE>

      (b)    The Master Servicer shall establish and maintain the Certificate
            Account into which the Master Servicer shall deposit or cause to be
            deposited 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,
                  including Principal Prepayments;

            (ii)   all payments on account of interest on the Mortgage Loans, 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, other than proceeds to be applied
                   to the restoration or repair of the Mortgaged Property or
                  released to the Mortgagor in accordance with the Master
                  Servicer's normal servicing procedures;

            (iv)   any amount required to be deposited by the Master Servicer
                  pursuant to Section 3.5(c) in connection with any losses on
                  Permitted Investments;

            (v)    any amounts required to be deposited by the Master Servicer
                  pursuant to Section 3.9(b) and 3.9(d);

            (vi)   all Substitution Adjustment Amounts;

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

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


                                       49
<PAGE>

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

            The foregoing requirements for remittance by the Master Servicer
      shall be exclusive, it being understood and agreed that, without limiting
      the generality of the foregoing, payments in the nature of prepayment
      penalties, late payment charges, assumption fees or amounts attributable
      to reimbursements of Advances, if collected, need not be remitted by the
      Master Servicer. In the event that the Master Servicer shall remit any
      amount not required to be remitted, it may at any time withdraw or direct
      the institution maintaining the Certificate Account to withdraw such
      amount from the Certificate Account, any provision herein to the contrary
      notwithstanding. Such withdrawal or direction may be accomplished by
      delivering written notice thereof to the Trustee or such other institution
      maintaining the Certificate Account which describes the amounts deposited
      in error in the Certificate Account. The Master Servicer shall maintain
      adequate records with respect to all withdrawals made pursuant to this
      Section. All funds deposited in the Certificate Account shall be held in
      trust for the Certificateholders until withdrawn in accordance with
      Section 3.8.

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

            (i)    the aggregate amount remitted by the Master Servicer to the
                  Trustee 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 Distribution Account, any provision herein to the
      contrary notwithstanding. Such direction may be accomplished by delivering
      an Officer's Certificate to the Trustee which describes the amounts
      deposited in error in the Distribution Account. All funds deposited in the
      Distribution Account shall be held by the Trustee in trust for the
      Certificateholders until disbursed in accordance with this Agreement or
      withdrawn in accordance with Section 3.8. In no event shall the Trustee
      incur liability for withdrawals from the Distribution Account at the
      direction of the Master Servicer.


                                       50
<PAGE>

            (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.


                                       51
<PAGE>

      (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
            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 pay to the
                  Master Servicer the master servicing 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;


                                       52
<PAGE>

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

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

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

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

            (vi)   to pay to the Seller or Master Servicer, as applicable, with
                  respect to each Mortgage Loan 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 Depositor
                  for expenses incurred by any of them and reimbursable pursuant
                  to Section 6.3 hereof;

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

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

            (x)    to clear and terminate the Certificate Account upon
                  termination of this Agreement pursuant to Section 9.1 hereof.

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


                                       53
<PAGE>

            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 Distribution Account for
            distributions to the Certificateholders in the manner specified in
            this Agreement (and to withhold from the amounts so withdrawn, the
            amount of any taxes that it is authorized to withhold pursuant to
            the last paragraph of Section 8.11). In addition, the Trustee may
            (and with respect to clauses (i) and (ii) below, shall), prior to
            making the distribution pursuant to Section 4.2 from time to time
            make withdrawals from the Distribution Account for the following
            purposes:

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

            (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 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.


                                       54
<PAGE>

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

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

      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.


                                        55
<PAGE>

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

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

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

      (b)    Subject to the Master Servicer's duty to enforce any due-on-sale
            clause to the extent set forth in Section 3.10(a) hereof, in any
            case in which a Mortgaged Property has been conveyed to a Person by
            a Mortgagor, and such Person is to enter into an assumption
            agreement or modification agreement or supplement to the Mortgage
            Note or Mortgage that requires the signature of the Trustee, or if
            an instrument of release signed by the Trustee is required releasing
            the Mortgagor from liability on the Mortgage Loan, the Master
            Servicer shall prepare and deliver or cause to be prepared and
            delivered to the Trustee for signature and shall direct, in writing,
            the Trustee to execute the assumption agreement with the Person to
            whom the Mortgaged Property is to be conveyed and such modification
