               (5)  The executed UCC-1 financing statement with
          evidence of  recording thereon which have been filed in

          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 Seller cannot deliver (i) the
original recorded Mortgage or (ii) all interim recorded
assignments satisfying the requirements of clause (b) or (c)
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 Seller 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 Seller 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 Seller 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 Seller shall forward or cause to be forwarded to the
Trustee or the Custodian on its behalf (i) from time to time
additional original documents evidencing an assumption or
modification of a Mortgage Loan and (ii) any other documents
required to be delivered by the Seller 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 Seller
shall execute and deliver or cause to be executed and delivered
such a document to the public recording office. In the case where
a public recording office retains the original recorded Mortgage
or in the case where a Mortgage is lost after recordation in a
public recording office, the Seller shall deliver 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 Seller 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 Seller shall promptly
deliver or cause to be delivered to

                               -7-

<PAGE>

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 Seller 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 Seller 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 anything to the contrary in this Agreement,
within thirty days after the Closing Date, the Seller 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 3.1 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 4.1 (treating
each Delay Delivery Mortgage Loan as a Deleted Mortgage Loan for
purposes of such Section 4.1), provided, however, that if the
Seller fails to deliver a Mortgage File for any Delay Delivery
Mortgage Loan within the thirty-day period provided in the prior
sentence, the Seller 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 4.1 hereof shall not
apply to the initial delivery of the Mortgage File for such Delay
Delivery Mortgage Loan, but rather the Seller shall have five (5)
Business Days to cure or cause to be cured such failure to
deliver.

          warranties set forth in Schedule B hereto to the
          Purchaser, as of the Closing Date, or if so specified
          therein, as of the Cut-off Date.

     (c)  Upon discovery by either of the parties hereto of a
          breach of a representation or warranty made pursuant to
          Schedule B hereto that materially and adversely affects
          the interests of the Purchaser in any Mortgage Loan,
          the party discovering such breach shall give prompt
          notice thereof to the other party. The Seller hereby
          covenants that within 90 days of the earlier of its
          discovery or its receipt of written notice from the
          Purchaser of a breach of any representation or warranty
          made pursuant to Schedule B hereto which materially and
          adversely

                               -9-

<PAGE>

          affects the interests of the Purchaser 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 pool of
          mortgages listed on Schedule B hereto 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 Purchaser at the Mortgage Loan Purchase
          Price in the manner set forth below.  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 Seller or
          the Purchaser 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 Purchaser
          therein, notwithstanding the Seller's lack of knowledge
          with respect to the substance of such representation or
          warranty, such inaccuracy shall be deemed a breach of
          the applicable representation or warranty.

          With respect to any Substitute Mortgage Loan or Loans,
     the Seller shall deliver to the Trustee or to the Custodian
     on its behalf the Mortgage Note, the Mortgage, the related
     assignment of the Mortgage, and such other documents and
     agreements as are required by Section 3.1, with the Mortgage
     Note endorsed and the Mortgage assigned as required by
     Section 3.1. 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 will be retained by the
     Seller.  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 hereto with
     respect to such Mortgage Loan.

          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 the Purchaser on
     its behalf.

     The representations and warranties contained in this
Agreement shall not be construed as a warranty or guaranty by the
Seller as to the future payments by any Mortgagor.

     It is understood and agreed that the representations and
warranties set forth in this Section 4.1 shall survive the sale
of the Mortgage Loans to the Purchaser hereunder.

                            ARTICLE V
                          Miscellaneous
                          -------------

     Section 5.1    TRANSFER INTENDED AS SALE.  It is the express
intent of the parties hereto that the conveyance of the Mortgage
Loans by the Seller to the Purchaser be, and be construed as, an
absolute sale thereof in accordance with GAAP and for regulatory
purposes.  It is, further, not the intention of the parties that
such conveyances be deemed a pledge thereof by the Seller to the

                              -10-

<PAGE>

Purchaser.  However, in the event that, notwithstanding the
intent of the parties, the Mortgage Loans are held to be the
property of the Seller or the Purchaser, respectively, or if for
any other reason this Agreement is held or deemed to create a
security interest in such assets, then (i) this Agreement shall
be deemed to be a security agreement within the meaning of the
Uniform Commercial Code of the State of Texas and (ii) the
conveyance of the Mortgage Loans provided for in this Agreement
shall be deemed to be an assignment and a grant by the Seller to
the Purchaser of a security interest in all of the Mortgage
Loans, whether now owned or hereafter acquired.

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

     Section 5.2    SELLER'S CONSENT TO ASSIGNMENT.  The Seller
hereby acknowledges the Purchaser's right to assign, transfer and
convey all of the Purchaser's rights under this Agreement to a
third party and that the representations and warranties made by
the Seller to the Purchaser pursuant to this Agreement will, in
the case of such assignment, transfer and conveyance, be for the
benefit of such third party.  The Seller hereby consents  to such
assignment, transfer and conveyance.

     Section 5.3    SPECIFIC PERFORMANCE.  Either party or its
assignees may enforce specific performance of this Agreement.

     Section 5.4    NOTICES.  All notices, demands and requests

                           SCHEDULE B
                           ----------

     Representations and Warranties as to the Mortgage Loans

     First Horizon Home Loan Corporation (the "Seller") hereby
makes the representations and warranties set forth in this
Schedule B on which First Tennessee Bank National Association
(the "Purchaser") relies in accepting the Mortgage Loans.  Such
representations and warranties speak as of the execution and
delivery of the Mortgage Loan Purchase Agreement, dated as of
July 30, 2004 (the "MLPA"), between First Horizon Home Loan
Corporation, as seller, and the Purchaser and as of the Closing
Date, or if so specified herein, as of the Cut-off Date or date
of origination of the Mortgage Loans, but shall survive the sale,
transfer, and assignment of the Mortgage Loans to the Purchaser
and any subsequent sale, transfer and assignment by the Purchaser
to a third party.  Capitalized terms used but not otherwise
defined in this Schedule B shall have the meanings ascribed
thereto in the MLPA.

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

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

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

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

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

                               B-1

<PAGE>

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

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

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

     (9)  No Mortgage Loan is a "high cost loan" as defined by
          the specific applicable predatory and abusive lending
          laws.

     (10) Except as reflected in a written document contained in
          the related Mortgage File, the Seller has not modified
          the Mortgage in any material respect; satisfied,
          cancelled or subordinated such Mortgage in whole or in
          part; released the related Mortgaged Property in whole
          or in part from the lien of such Mortgage; or executed
          any instrument of release, cancellation, modification
          or satisfaction with respect thereto.

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

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

     (13) To the best of the Seller's knowledge, as of the date
          of origination of each Mortgage Loan, no improvement
          located on or being part of the Mortgaged Property is
          in violation of any applicable zoning law or regulation
          unless such violation would not have a material adverse
          effect on the value of the related

                               B-2

<PAGE>

          Mortgaged Property. To the best of the Seller's
          knowledge, all inspections, licenses and certificates
          required to be made or issued with respect to all
          occupied portions of the Mortgaged Property and, with
          respect to the use and occupancy of the same, including
          but not limited to certificates of occupancy and fire
          underwriting certificates, have been made or obtained
          from the appropriate authorities, unless the lack
          thereof would not have a material adverse effect on the
          value of such Mortgaged Property.

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

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

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

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

     (18) As of the Closing Date, the improvements upon each
          Mortgaged Property are covered by a valid and existing
          hazard insurance policy with a generally acceptable
          carrier that provides for fire and extended coverage
          and coverage for such other hazards as are customarily
          required by institutional single family mortgage
          lenders in the area where the Mortgaged Property is
          located, and the Seller has received no notice that any
          premiums due and payable thereon have not been paid;
          the Mortgage obligates the Mortgagor thereunder to
          maintain all such insurance including flood insurance
          at the Mortgagor's cost and expense. Anything to the
          contrary in this item (18) notwithstanding, no breach
          of this item (18) shall be deemed to give rise to any
          obligation of the Seller to repurchase or substitute
          for such affected Mortgage Loan or Loans so long as the
          Seller maintains a blanket policy.

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

                               B-3

<PAGE>

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

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

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

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

     (24) The Mortgage Loans provide for the full amortization of
          the amount financed over a series of monthly payments.

     (25) At origination, substantially all of the Mortgage Loans
          in the Mortgage Pools had stated terms to maturity of
          30 years.

     (26) Scheduled monthly payments made by the Mortgagors on
          the Mortgage Loans either earlier or later than their
          Due Dates will not affect the amortization schedule or
          the relative application of the payments to principal
          and interest.

     (27) The Mortgage Loans may be prepaid at any time by the
          related Mortgagors without penalty.

     (28) Substantially all of the Mortgage Loans are jumbo
          mortgage loans that have Stated Principal Balances at
          origination that exceed the then applicable limitations
          for purchase by Fannie Mae and Freddie Mac.

     (29) Each Mortgage Loan was originated on or after January
          26, 2004.

     (30) The latest stated maturity date of any Mortgage Loan is
          August 1, 2034, and the earliest stated maturity date
          of any Mortgage Loan is June 1, 2024.

     (31) No Mortgage Loan was delinquent more than 30 days as of
          the Cut-off Date.

     (32) No Mortgage Loan had a Loan-to-Value Ratio at
          origination of more than 95%. Generally, each  Mortgage
          Loan with a Loan-to-Value Ratio at origination of
          greater than 80% is covered by a Primary Insurance
          Policy issued by a mortgage insurance company that is
          acceptable to Fannie Mae or Freddie Mac.

                               B-4

<PAGE>

     (33) Each Mortgage Loan constitutes a "qualified mortgage"
          within the meaning of Section 860G(a)(3) of the Code.

     (34) No Mortgage Loan is a "high cost loan" as defined by
          the specific applicable predatory and abusive lending
          laws.  In addition, no Mortgage Loan is a "High Cost
          Loan" or a "Covered Loan", as applicable (as such terms
          are defined in the then current Standard & Poor's
          LEVELS Glossary which is now Version 5.6 Revised,
          Appendix E) and no Mortgage Loan originated on or after
          October 1, 2002 through March 6, 2003 is governed by
          the Georgia Fair Lending Act.
