            been returned from the   applicable   public   recording   office,   such

            assignment   of   the   Mortgage   may   exclude   the   information   to be

            provided by the recording office;

 

      (iv)   the   original or copies of each   assumption,   modification,   written

            assurance or substitution agreement, if any;

 

      (v)    either the original or duplicate original title policy, or a copy of

            such   title   policy   certified   by the   Seller   as   being a true and

            complete copy of the title policy,   (including   all riders   thereto)

            with   respect   to the   related   mortgaged   property,   if   available,

            provided that the title policy   (including all riders   thereto) will

            be   delivered   as soon as it   becomes   available,   and if the   title

            policy is not available,   and to the extent required pursuant to the

            second paragraph below or otherwise in connection with the rating of

            the   Certificates,    a   written   commitment   or   interim   binder   or

            preliminary   report of the title   issued by the title   insurance   or

            escrow   company with respect to the mortgaged   property,   or in lieu

            thereof,   an Alternative Title Product or a copy of such Alternative

            Title   Product   certified by the Seller as being a true and complete

            copy of the Alternative Title Product, and

 

                                       35

<PAGE>

 

      (vi)   in the case of a   Cooperative   Loan,   the originals of the following

            documents or instruments:

 

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

 

            (B)    The executed Security Agreement;

 

            (C)    The executed Proprietary Lease;

 

            (D)    The executed Recognition Agreement;

 

            (E)    The   executed   UCC-1   financing   statement   with   evidence   of

                  recording thereon which have been filed in all places required

                   to perfect   the   Seller's   interest in the Coop Shares and the

                  Proprietary Lease; and

 

            (F)    Executed UCC-3 financing   statements or other   appropriate UCC

                  financing   statements   required   by state   law,   evidencing   a

                  complete and unbroken   line from the   mortgagee to the Trustee

                  with evidence of recording   thereon (or in a form suitable for

                  recordation).

 

      In the event that in connection   with any Mortgage Loan that is not a MERS

Mortgage Loan the Depositor cannot deliver (a) the original recorded Mortgage or

(b) all interim recorded assignments   satisfying the requirements of clause (ii)

or (iii)   above,   respectively,   concurrently   with the   execution   and delivery

hereof   because   such   document or   documents   have not been   returned   from the

applicable   public   recording   office,   the Depositor shall promptly   deliver or

cause to be   delivered   to the   Trustee   or the   Custodian   on its   behalf   such

original Mortgage or such interim assignment,   as the case may be, with evidence

of recording   indicated   thereon upon receipt thereof from the public   recording

office, or a copy thereof,   certified, if appropriate, by the relevant recording

office,   but in no event shall any such   delivery of the   original   Mortgage and

each such interim assignment or a copy thereof,   certified,   if appropriate,   by

the relevant recording office, be made later than one year following the Closing

Date;   provided,   however,   in the event the   Depositor   is unable to deliver or

cause   to be   delivered   by such   date   each   Mortgage   and   each   such   interim

assignment by reason of the fact that any such   documents have not been returned

by the   appropriate   recording   office,   or,   in the case of each   such   interim

assignment,    because   the   related   Mortgage   has   not   been   returned   by   the

appropriate   recording   office,   the   Depositor   shall   deliver   or   cause to be

delivered   such   documents   to the   Trustee   or the   Custodian   on its behalf as

promptly as possible   upon receipt   thereof   and, in any event,   within 720 days

following the Closing Date. The Depositor shall forward or cause to be forwarded

to the Trustee or the   Custodian on its behalf (a) from time to time   additional

original   documents   evidencing an assumption or modification of a Mortgage Loan

and (b) any other   documents   required to be delivered   by the   Depositor or the

Master Servicer to the Trustee.   In the event that the original   Mortgage is not

delivered   and in   connection   with the payment in full of the related   Mortgage

Loan and the   public   recording   office   requires   the   presentation   of a "lost

instruments affidavit and indemnity" or any equivalent document,   because only a

copy of the Mortgage can be delivered   with the   instrument of   satisfaction   or

reconveyance,   the Master   Servicer   shall   execute   and   deliver or cause to be

executed and delivered such a document to the public   recording   office.   In the

case where a public recording office retains the original   recorded   Mortgage or

in the case where a Mortgage   is lost after   recordation   in a public   recording

office,   the Depositor   shall deliver or cause to be delivered to the Trustee or

the   Custodian   on its behalf a copy of such   Mortgage   certified by such public

recording   office   to be a true   and   complete   copy   of the   original   recorded

Mortgage.

 

                                       36

<PAGE>

 

      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.

 

      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-AR4, 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.

 

                                       37

<PAGE>

 

      In the case of   Mortgage   Loans   that have been   prepaid in full as of the

Closing Date,   the Depositor,   in lieu of delivering the above   documents to the

Trustee or the Custodian on its behalf,   will deposit in the Certificate Account

the portion of such payment that is required to be deposited in the   Certificate

Account pursuant to Section 3.8 hereof.

 

      Notwithstanding anything to the contrary in this Agreement,   within thirty

days after the Closing Date, the Depositor   shall either (i) deliver or cause to

be delivered to the Trustee or the   Custodian on its behalf the Mortgage File as

required   pursuant to this Section 2.1 for each Delay Delivery   Mortgage Loan or

(ii) (A)   substitute or cause to be   substituted a Substitute   Mortgage Loan for

the Delay   Delivery   Mortgage Loan or (B)   repurchase or cause to be repurchased

the Delay Delivery   Mortgage Loan,   which   substitution   or repurchase   shall be

accomplished   in the manner and subject to the   conditions   set forth in Section

2.3 (treating each Delay Delivery   Mortgage Loan as a Deleted   Mortgage Loan for

purposes of such Section 2.3), provided, however, that if the Depositor fails to

deliver   a   Mortgage   File for any   Delay   Delivery   Mortgage   Loan   within   the

thirty-day   period provided in the prior   sentence,   the Depositor shall use its

best reasonable efforts to effect or cause to be effected a substitution, rather

than a repurchase of, such Deleted   Mortgage Loan and provided   further that the

cure period provided for in Section 2.2 or in Section 2.3 shall not apply to the

initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan, but

rather the   Depositor   shall have five (5) Business   Days to cure or cause to be

cured such failure to deliver. At the end of such thirty-day period, the Trustee

or the Custodian,   on its behalf shall send a Delay Delivery   Certification   for

the Delay Delivery   Mortgage Loans delivered   during such   thirty-day   period in

accordance with the provisions of Section 2.2.   Notwithstanding   anything to the

contrary   contained in this   Agreement,   none of the Mortgage Loans in the Trust

Fund is or will be Delay Delivery Mortgage Loans.

 

      SECTION 2.2 Acceptance by Trustee of the Mortgage Loans.

 

      The   Trustee   or the   Custodian,   on behalf of the   Trustee,   acknowledges

receipt of the   documents   identified in the Initial   Certification   in the form

annexed hereto as Exhibit E and declares that it or the Custodian holds and will

hold such documents and the other documents delivered to it or the Custodian, as

applicable,   constituting the Mortgage Files,   and that it or the Custodian,   as

applicable,   holds or will hold such other   assets as are   included in the Trust

Fund,   in trust for the   exclusive   use and   benefit of all   present   and future

Certificateholders.   The Trustee   acknowledges   that the Custodian will maintain

possession   of the   Mortgage   Notes in the   State   of   Texas,   unless   otherwise

permitted by the Rating Agencies.

 

      The Trustee   agrees to execute and   deliver or to cause the   Custodian   to

execute and deliver on the Closing Date to the Depositor and the Master Servicer

an Initial   Certification   in the form annexed hereto as Exhibit E. Based on its

or the   Custodian's   review   and   examination,   and   only   as to   the   documents

identified   in such   Initial   Certification,   the   Custodian,   on   behalf of the

Trustee,   acknowledges   that such   documents   appear   regular   on their face and

relate to such Mortgage   Loan.   Neither the Trustee nor the   Custodian   shall be

under any duty or   obligation   to   inspect,   review or examine   said   documents,

instruments,   certificates   or   other   papers   to   determine   that   the same are

genuine,   enforceable or appropriate   for the   represented   purpose or that they

have actually   been   recorded in the real estate   records or that they are other

than what they purport to be on their face.

 

                                       38

<PAGE>

 

      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 Subsequent   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    Subsequent

Certification;   provided,   however   that   neither the Trustee nor the   Custodian

shall make any   determination as to whether (i) any endorsement is sufficient to

transfer all right, title and interest of the party so endorsing,   as noteholder

or assignee   thereof,   in and to that Mortgage Note or (ii) any assignment is in

recordable form or is sufficient to effect the assignment of and transfer to the

assignee thereof under the mortgage to which the assignment relates.   The Seller

shall   promptly   correct or cure such defect within 90 days from the date it was

so   notified   of such   defect   and,   if the Seller does not correct or cure such

defect   within such   period,   the Seller   shall   either (a)   substitute   for the

related Mortgage Loan a Substitute   Mortgage Loan, which   substitution   shall be

accomplished   in the manner and subject to the   conditions   set forth in Section

2.3, or (b) purchase such Mortgage Loan from the Trustee within 90 days from the

date the Seller was notified of such defect in writing at the Purchase   Price of

such Mortgage Loan; provided,   however, that in no event shall such substitution

or purchase   occur more than 540 days from the Closing Date,   except that if the

substitution   or   purchase of a Mortgage   Loan   pursuant   to this   provision   is

required by reason of a delay in delivery of any   documents   by the   appropriate

recording   office,   and there is a dispute between either the Master Servicer or

the Seller and the Trustee over the location or status of the recorded document,

then such   substitution or purchase shall occur within 720 days from the Closing

Date. The Trustee shall deliver or shall cause the Custodian to deliver   written

notice to each Rating   Agency   within 270 days from the Closing Date   indicating

each Mortgage Loan (a) which has not been returned by the appropriate   recording

office or (b) as to which   there is a dispute as to   location   or status of such

Mortgage Loan. Such notice shall be delivered every 90 days thereafter until the

related Mortgage Loan is returned to the Trustee or the Custodian on its behalf.

Any such   substitution   pursuant to (a) above or purchase   pursuant to (b) above

shall not be   effected   prior to the   delivery   to the Trustee of the Opinion of

Counsel required by Section 2.5 hereof, if any, and any substitution pursuant to

(a) above shall not be effected prior to the additional   delivery to the Trustee

of a Request for Release substantially in the form of Exhibit L. No substitution

is permitted to be made in any calendar month after the   Determination   Date for

such month.   The Purchase Price for any such Mortgage Loan shall be deposited by

the Seller in the Certificate   Account on or prior to the   Distribution   Account

Deposit   Date for the   Distribution   Date in the   month   following   the month of

repurchase   and,   upon   receipt of such deposit and   certification   with respect

thereto in the form of Exhibit M hereto,   the Trustee   shall cause the Custodian

to release the related Mortgage File to the Seller and shall execute and deliver

at the Seller's request such   instruments of transfer or assignment   prepared by

the Seller, in each case without recourse,   as shall be necessary to vest in the

Seller,   or a designee,   the   Trustee's   interest in any Mortgage   Loan released

pursuant hereto. If pursuant to the foregoing   provisions the Seller repurchases

a Mortgage Loan that is a MERS Mortgage Loan,   the Master   Servicer shall either

(i)   cause   MERS to   execute   and   deliver   an   assignment   of the   Mortgage   in

recordable form to transfer the Mortgage from MERS to the Seller and shall cause

such   Mortgage   to be   removed   from   registration   on   the   MERS(R)   System   in

accordance   with MERS' rules and   regulations or (ii) cause MERS to designate on

the MERS(R) System the Seller as the beneficial holder of such Mortgage Loan.

      The Trustee shall retain or shall cause the Custodian to retain possession

and custody of each Mortgage   File in   accordance   with and subject to the terms

and conditions set forth herein.   The Master Servicer shall promptly   deliver to

the   Trustee or the   Custodian   on its   behalf,   upon the   execution   or receipt

thereof,   the originals of such other documents or instruments   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 MLPA I, which contains,   among other   representations   and

warranties, 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 MLPA I, are

required   to   conform   to,   among   other    representations   and   warranties,    a

representation and warranty of the Seller set forth in MLPA I 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 MLPA I

            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 MLPA I which   materially   and adversely   affects the interests of

 

 

                                       40

<PAGE>

 

            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.

 

      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

MLPA I 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   Balan
