                thereto) with respect to the related Mortgaged Property, if available,
                provided that the title policy (including all riders thereto) will
                be
                delivered as soon as it becomes available, and if the title policy
                is not

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

            


    

     

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

     

    (2) The
      executed Security Agreement;

     

    (3) The
      executed Proprietary Lease;

     

    (4) The
      executed Recognition Agreement;

     

    (5) The
      executed UCC-1 financing statement with evidence of recording thereon which
      have
      been filed in all places required to perfect the Seller’s interest in the Coop
      Shares and the Proprietary Lease; and

     

    (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.

     

    
      
        
        

      

      
        -7-

        
          

        

      

      
        
        

      

    

     

    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.

    Representations
      and Warranties

     

    Section
      4.1 Representations
      and Warranties of the Seller.
      (a) The
      Seller hereby represents and warrants to the Purchaser, as of the date of
      execution and delivery hereof, that:

     

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

     

    
      
        
        

      

      
        -8-

        
          

        

      

      
        
        

      

    

     

    (2) The
      Seller has the full corporate power and authority to sell each Mortgage Loan,
      and to execute, deliver and perform, and to enter into and consummate the
      transactions contemplated by this Agreement and has duly authorized by all
      necessary corporate action on the part of the Seller the execution, delivery
      and
      performance of this Agreement; and this Agreement, assuming the due
      authorization, execution and delivery thereof by the other parties thereto,
      constitutes a legal, valid and binding obligation of the Seller, enforceable
      against the Seller in accordance with its terms, except that (a) the
      enforceability thereof may be limited by bankruptcy, insolvency, moratorium,
      receivership and other similar laws relating to creditors’ rights generally and
      (b) the remedy of specific performance and injunctive and other forms of
      equitable relief may be subject to equitable defenses and to the discretion
      of
      the court before which any proceeding therefor may be brought.

     

    (3) The
      execution and delivery of this Agreement by the Seller, the sale of the Mortgage
      Loans by the Seller under this Agreement, the consummation of any other of
      the
      transactions contemplated by this Agreement, and the fulfillment of or
      compliance with the terms thereof are in the ordinary course of business of
      the
      Seller and will not (a) result in a material breach of any term or provision
      of
      the charter or by-laws of the Seller or (b) materially conflict with, result
      in
      a material breach, violation or acceleration of, or result in a material default
      under, the terms of any other material agreement or instrument to which the
      Seller is a party or by which it may be bound, or (c) constitute a material
      violation of any statute, order or regulation applicable to the Seller of any
      court, regulatory body, administrative agency or governmental body having
      jurisdiction over the Seller; and the Seller is not in breach or violation
      of
      any material indenture or other material agreement or instrument, or in
      violation of any statute, order or regulation of any court, regulatory body,
      administrative agency or governmental body having jurisdiction over it which
      breach or violation may materially impair 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.

              The

                Schedule
                B
                hereto to the Purchaser, as of the Closing Date, or if so specified

              (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 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.

    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

      receipt requested, to the parties at their respective addresses as

      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 February
      28,
      2007 (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 February 1, 2007, between First Horizon Asset Securities
      Inc., as depositor, First Horizon Home Loan Corporation, as master servicer,

              (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

        
          

        

      

      
        
        

      

    

     

    
      	 	
              (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.

            


    

     

    
      	 	
              (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.

              (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
