<PAGE>

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

                 (2)  The executed Security Agreement;

                 (3)  The executed Proprietary Lease;

             recording thereon which have been filed in all places required
             to perfect the Seller's interest in the Coop Shares and the
             Proprietary Lease; and

                 (6)  Executed UCC-3 financing statements or other appropriate
             UCC financing statements required by state law, evidencing a
             complete and unbroken line from the mortgagee to the Trustee
             with evidence of recording thereon (or in a form suitable for
             recordation).

         In the event that in connection with any Mortgage Loan that is not a
MERS Mortgage Loan the 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; provided,
further, however, that the Seller shall not be required to provide an original
or duplicate lender's title policy (together with all riders thereto) if the
Seller delivers an Alternative Title Product in lieu thereof. 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 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.

         agency or governmental body having jurisdiction over it which breach or
         violation may materially impair the Seller's ability to perform or meet
         any of its obligations under this Agreement.

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

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

    (b)      The Seller hereby makes the representations and 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 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 pools 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.

                                  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
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 that may be
given or that are required to be given hereunder shall be sent by United States

                                   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
Horizon Asset Securities Inc. (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 April 29, 2005
(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 or the Pooling and Servicing
Agreement, dated as of April 1, 2005, between First Horizon Asset Securities
Inc., as depositor, First Horizon Home Loan Corporation, as master servicer, and
The Bank of New York, as trustee.

         (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.

                                      B-1
<PAGE>

         (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.

         (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. With respect to the representations and warranties
              contained within this item (7) that are made to the knowledge or
              the best knowledge of the Seller or as to which the Seller has no
              knowledge, if it is discovered that the substance of any such
              representation and warranty is inaccurate and the inaccuracy
              materially and adversely affects the value of the related Mortgage
              Loan, or the interest therein of the Purchaser, then
              notwithstanding the Seller's lack of knowledge with respect to the
              substance of such representation and warranty being inaccurate at
              the time the representation and warranty was made, such inaccuracy
              shall be deemed a breach of the applicable representation and
              warranty and the Seller shall take such action described in
              Section 4.1(c) of this Agreement in respect of 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, or, in lieu thereof, an Alternative Title Product.

                                      B-2
<PAGE>

         (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
              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 Loans 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.

                                      B-3
<PAGE>

         (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.

         (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
              fixed-rate one- to four-family mortgage loans in the Seller's
              portfolio at the Closing Date as to which the representations and
              warranties made with respect to the Mortgage Loans set forth in
              this Schedule 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
