(b)   In connection with the transfer and assignment set forth in clause (a) above, the Depositor has delivered or caused to be delivered to the Trustee or the Custodian on its behalf (or, in the case of the Delay Delivery Mortgage Loans, will deliver or cause to be delivered to the Trustee or the Custodian on its behalf within thirty (30) days following the Closing Date) for the benefit of the Certificateholders the following documents or instruments with respect to each Mortgage Loan so assigned:

(i)   (A) the original Mortgage Note endorsed by manual or facsimile signature in blank in the following form: “Pay to the order of    , without recourse,” with all intervening endorsements showing a complete chain of endorsement from the originator to the Person endorsing the Mortgage Note (each such endorsement being 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

(B) with respect to any Lost Mortgage Note, a lost note affidavit from the   Seller stating that the original Mortgage Note was lost or destroyed,   together with a copy of such Mortgage Note;

(ii)   except as provided below and for each Mortgage Loan that is not a MERS Mortgage Loan, the original recorded Mortgage or a copy of such Mortgage certified by the Seller as being a true and complete copy of the Mortgage, and in the case of each MERS Mortgage Loan, the original recorded Mortgage, noting the presence of the MIN of the Mortgage Loans and either language indicating that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM Loan or if the Mortgage Loan was not a MOM Loan at origination, the original Mortgage and the assignment thereof to MERS, with evidence of recording indicated thereon, or a copy of the Mortgage certified by the Seller as being a true and complete copy of the Mortgage;

(iii)   in the case of a Mortgage Loan that is not a MERS Mortgage Loan, a duly executed assignment of the Mortgage, or a copy of such assignment certified by the Seller as being a true and complete copy of the assignment, in blank (which may be included in a blanket assignment or assignments), together with, except as provided below, all interim recorded assignments, or copies of such interim assignments certified by the Seller as being true and complete copies of the interim assignments, of such Mortgage (each such assignment, when duly and validly completed, to be in recordable form and sufficient to effect the assignment of and transfer to the assignee thereof, under the Mortgage to which the assignment relates); provided that, if the related Mortgage has not 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

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

In the event that in connection with any Mortgage Loan that is not a MERS Mortgage Loan the Depositor cannot deliver (a) the original recorded Mortgage or (b) all interim recorded assignments satisfying the requirements of clause (ii) or (iii) above, respectively, concurrently with the execution and delivery hereof because such document or documents have not been returned from the applicable public recording office, the Depositor shall promptly deliver or cause to be delivered to the Trustee or the Custodian on its behalf such original Mortgage or such interim assignment, as the case may be, with evidence of recording indicated thereon upon receipt thereof from the public recording office, or a copy thereof, certified, if appropriate, by the relevant recording office, but in no event shall any such delivery of the original Mortgage and each such interim assignment or a copy thereof, certified, if appropriate, by the relevant recording office, be made later than one year following the Closing Date; provided, however, in the event the Depositor is unable to deliver or cause to be delivered by such date each Mortgage and each such interim assignment by reason of the fact that any such documents have not been returned by the appropriate recording office, or, in the case of each such interim assignment, because the related Mortgage has not been returned by the appropriate recording office, the Depositor shall deliver or cause to be delivered such documents to the Trustee or the Custodian on its behalf as promptly as possible upon receipt thereof and, in any event, within 720 days following the Closing Date. The Depositor shall forward or cause to be forwarded to the Trustee or the Custodian on its behalf (a) from time to time additional original documents evidencing an assumption or modification of a Mortgage Loan and (b) any other documents required to be delivered by the Depositor or the Master Servicer to the Trustee. In the event that the original Mortgage is not delivered and in connection with the payment in full of the related Mortgage Loan and the public recording office requires the presentation of a “lost instruments affidavit and indemnity” or any equivalent document, because only a copy of the Mortgage can be delivered with the instrument of satisfaction or reconveyance, the Master Servicer shall execute and deliver or cause to be executed and delivered such a document to the public recording office. In the case where a public recording office retains the original recorded Mortgage or in the case where a Mortgage is lost after recordation in a public recording office, the Depositor shall deliver or cause to be delivered to the Trustee or the Custodian on its behalf a copy of such Mortgage certified by such public recording office to be a true and complete copy of the original recorded Mortgage.

In addition, in the event that in connection with any Mortgage Loan the Depositor cannot deliver or cause to be delivered the original or duplicate original lender’s title policy (together with all riders thereto), satisfying the requirements of clause (v) above, concurrently with the execution and delivery hereof because the related Mortgage has not been returned from the applicable public recording office, the Depositor shall promptly deliver or cause to be delivered to the Trustee or the Custodian on its behalf such original or duplicate original lender’s title policy (together with all riders thereto) upon receipt thereof from the applicable title insurer, but in no event shall any such delivery of the original or duplicate original lender’s title policy be made later than one year following the Closing Date; provided, however, in the event the Depositor is unable to deliver or cause to be delivered by such date the original or duplicate original lender’s title policy (together with all riders thereto) because the related Mortgage has not been returned by the appropriate recording office, the Depositor shall deliver or cause to be delivered such documents to the Trustee or the Custodian on its behalf as promptly as possible upon receipt thereof and, in any event, within 720 days following the Closing Date; provided further, however, that the Depositor shall not be required to deliver an original or duplicate lender’s title policy (together with all riders thereto) if the Depositor delivers an Alternative Title Product in lieu thereof. Notwithstanding the preceding, in connection with any Mortgage Loan for which either the original or duplicate original title policy has not been delivered to the Trust, if at any time during the term of this Agreement the parent company of the Seller does not have a long term senior debt rating of A- or higher from S&P and A- or higher from Fitch (if rated by Fitch), then the Depositor shall within 30 days deliver or cause to be delivered to the Trustee or the Custodian on its behalf (if it has not previously done so) a written commitment or interim binder or preliminary report of the title issued by the title insurance or escrow company with respect to the Mortgaged Property.

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 2006-AA7, The Bank of New York, as trustee for the holders of the Certificates”, (ii) cause such assignment to be in proper form for recording in the appropriate public office for real property records and (iii) cause to be delivered for recording in the appropriate public office for real property records the assignments of the Mortgages to the Trustee, except that, with respect to any assignments of Mortgage as to which the Master Servicer has not received the information required to prepare such assignment in recordable form, the Master Servicer’s obligation to do so and to deliver the same for such recording shall be as soon as practicable after receipt of such information and in any event within thirty (30) days after receipt thereof. Notwithstanding the foregoing, the Master Servicer need not cause to be recorded any assignment which relates to a Mortgage Loan in any state other than the Required Recordation States.

In the case of Mortgage Loans that have been prepaid in full as of the Closing Date, the Depositor, in lieu of delivering the above documents to the Trustee or the Custodian on its behalf, will deposit in the Certificate Account the portion of such payment that is required to be deposited in the Certificate Account pursuant to Section 3.8 hereof.

Notwithstanding anything to the contrary in this Agreement, within thirty days after the Closing Date, the Depositor shall either (i) deliver or cause to be delivered to the Trustee or the Custodian on its behalf the Mortgage File as required pursuant to this Section 2.1 for each Delay Delivery Mortgage Loan or (ii) (A) substitute or cause to be substituted a Substitute Mortgage Loan for the Delay Delivery Mortgage Loan or (B) repurchase or cause to be repurchased the Delay Delivery Mortgage Loan, which substitution or repurchase shall be accomplished in the manner and subject to the conditions set forth in Section 2.3 (treating each Delay Delivery Mortgage Loan as a Deleted Mortgage Loan for purposes of such Section 2.3), provided, however, that if the Depositor fails to deliver a Mortgage File for any Delay Delivery Mortgage Loan within the thirty-day period provided in the prior sentence, the Depositor shall use its best reasonable efforts to effect or cause to be effected a substitution, rather than a repurchase of, such Deleted Mortgage Loan and provided further that the cure period provided for in Section 2.2 or in Section 2.3 shall not apply to the initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan, but rather the Depositor shall have five (5) Business Days to cure or cause to be cured such failure to deliver. At the end of such thirty-day period, the Trustee or the Custodian, on its behalf shall send a Delay Delivery Certification for the Delay Delivery Mortgage Loans delivered during such thirty-day period in accordance with the provisions of Section 2.2. Notwithstanding anything to the contrary contained in this Agreement, none of the Mortgage Loans in the Trust Fund is or will be Delay Delivery Mortgage Loans.

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.

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 (delivery of which to the Custodian will be by electronic data transmission or email), 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® System in accordance with MERS’ rules and regulations or (ii) cause MERS to designate on the MERS® System the Seller as the beneficial holder of such Mortgage Loan.

The Trustee shall retain or shall cause the Custodian to retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions set forth herein. The Master Servicer shall promptly deliver to the Trustee or the Custodian on its behalf, upon the execution or receipt thereof, the originals of such other documents or instruments constituting the Mortgage File as come into the possession of the Master Servicer from time to time.

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

The mortgage loans permitted by the terms of this Agreement to be included in the Trust Fund are limited to (i) the Mortgage Loans (which the Depositor acquired pursuant to the MLPA, 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 the MLPA, are required to conform to, among other representations and warranties, a representation and warranty of the Seller set forth in the MLPA that no Substitute Mortgage Loan is a “high cost loan” as defined by the specific applicable local, state or federal predatory and abusive lending laws). It is therefore understood and agreed by the parties hereto that it is not intended that any Mortgage Loan be included in the Trust Fund that is a “high cost loan” as defined by the specific applicable local, state or federal predatory and abusive lending laws.

SECTION 2.3   Representations and Warranties of the Master Servicer; Covenants of the Seller.

(a)   The Master Servicer hereby makes the representations and warranties set forth in Schedule II hereto and by this reference incorporated herein, to the Depositor and the Trustee, as of the Closing Date, or if so specified therein, as of the Cut-off Date.

(b)   Upon discovery by any of the parties hereto of a breach of a representation or warranty made pursuant to Schedule B to the MLPA that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt notice thereof to the other parties. The Seller hereby covenants that within 90 days of the earlier of its discovery or its receipt of written notice from any party of a breach of any representation or warranty made pursuant to Schedule B to the MLPA which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, it shall cure such breach in all material respects, and if such breach is not so cured, shall, (i) if such 90-day period expires prior to the second anniversary of the Closing Date, remove such Mortgage Loan (a “Deleted Mortgage Loan”) from the Trust Fund and substitute in its place a Substitute Mortgage Loan, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below; provided, however, that any such substitution pursuant to (i) above shall not be effected prior to the delivery to the Trustee of the Opinion of Counsel required by Section 2.5 hereof, if any, and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery to the Trustee or the Custodian on its behalf of a Request for Release substantially in the form of Exhibit M (delivery of which to the Custodian will be by electronic data transmission or email) 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 the MLPA with respect to such Mortgage Loan. Upon any such substitution and the deposit to the Certificate Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Trustee shall, upon the delivery to the Trustee of a Request for Release in the form of Exhibit L, release or shall cause the Custodian to release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the Seller and shall execute and deliver at the Seller’s direction such instruments of transfer or assignment prepared by the Seller, in each case without recourse, as shall be necessary to vest title in the Seller, or its designee, the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.3.

For any month in which the Seller substitutes one or more Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer will determine the amount (if any) by which the aggregate principal balance of all such Substitute Mortgage Loans as of the date of substitution is less than the aggregate Stated Principal Balance of all such Deleted Mortgage Loans (after application of the scheduled principal portion of the monthly payments due in the month of substitution). The amount of such shortage (the “Substitution Adjustment Amount”) plus an amount equal to the aggregate of any unreimbursed Advances with respect to such Deleted Mortgage Loans shall be deposited in the Certificate Account by the Seller on or before the Distribution Account Deposit Date for the Distribution Date in the month succeeding the calendar month during which the related Mortgage Loan became required to be purchased or replaced hereunder.

In the event that the Seller shall have repurchased a Mortgage Loan, the Purchase Price therefor shall be deposited in the Certificate Account pursuant to Section 3.5 on or before the Distribution Account Deposit Date for the Distribution Date in the month following the month during which the Seller became obligated hereunder to repurchase or replace such Mortgage Loan and upon such deposit of the Purchase Price, the delivery of the Opinion of Counsel required by Section 2.5 and receipt of a Request for Release in the form of Exhibit M hereto, the Trustee shall release or shall cause the Custodian to release the related Mortgage File held for the benefit of the Certificateholders to such Person, and the Trustee shall execute and deliver or shall cause the Custodian to execute and deliver at such Person’s direction such instruments of transfer or assignment prepared by such Person, in each case without recourse, as shall be necessary to transfer title from the Trustee. It is understood and agreed that the obligation under this Agreement of the Seller to cure, repurchase or replace any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedy against the Seller respecting such breach available to Certificateholders, the Depositor or the Trustee on their behalf.

After giving effect to the sale of the Certificates by the Depositor to the Underwriter, and thereafter, so long as any Certificates remain outstanding, the Seller, its affiliates and agents, collectively, shall not beneficially own Certificates the aggregate fair value of which would represent 90% or more of the beneficial interests in the Trust Fund.

The representations and warranties made pursuant to this Section 2.3 shall survive delivery of the respective Mortgage Files to the Trustee or the Custodian for the benefit of the Certificateholders.

SECTION 2.4   Representations and Warranties of the Depositor as to the Mortgage Loans.

The Depositor hereby represents and warrants to the Trustee with respect to each Mortgage Loan as of the date hereof or such other date set forth herein that as of the Closing Date, and following the transfer of the Mortgage Loans to it pursuant to the MLPA and immediately prior to the conveyance of the Mortgage Loans by it to the Trustee pursuant to Section 2.1(a) hereof, the Depositor had good title to the Mortgage Loans and the Mortgage Notes were subject to no offsets, defenses or counterclaims.

It is understood and agreed that the representations and warranties set forth in this Section 2.4 shall survive delivery of the Mortgage Files to the Trustee. Upon discovery by the Depositor or the Trustee of a breach of any of the foregoing representations and warranties set forth in this Section 2.4 (referred to herein as a “breach”), which breach materially and adversely affects the interest of the Certificateholders, the party discovering such breach shall give prompt written notice to the others and to each Rating Agency.

SECTION 2.5   Delivery of Opinion of Counsel in Connection with Substitutions.

(a)   Notwithstanding any contrary provision of this Agreement, no substitution pursuant to Section 2.2 or Section 2.3 shall be made more than 90 days after the Closing Date unless the Depositor delivers to the Trustee an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of either the Trustee or the Trust Fund, addressed to the Trustee, to the effect that such substitution will not (i) result in the imposition of the tax on “prohibited transactions” on the Trust Fund or contributions after the Startup Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively, or (ii) cause the REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding.

(b)   Upon discovery by the Depositor, the Master Servicer or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall promptly (and in any event within five (5) Business Days of discovery) give written notice thereof to the other parties. In connection therewith, the Trustee shall require the Depositor to cause the Seller, pursuant to the MLPA and at the Seller’s option, to either (i) substitute, if the conditions in Section 2.3(b) with respect to substitutions are satisfied, a Substitute Mortgage Loan for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90 days of such discovery in the same manner as it would a Mortgage Loan for a breach of representation or warranty made pursuant to Section 2.3. The Trustee shall reconvey or shall cause the Custodian to reconvey to the Seller the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty contained in Section 2.3.

The Master Servicer hereby covenants to the Depositor and the Trustee as follows:

(a)   the Master Servicer shall comply in the performance of its obligations under this Agreement with all reasonable rules and requirements of the insurer under each Required Insurance Policy; and

(b)   no written information, certificate of an officer, statement furnished in writing or written report delivered to the Depositor, any affiliate of the Depositor or the Trustee and prepared by the Master Servicer pursuant to this Agreement will contain any untrue statement of a material fact or omit to state a material fact necessary to make such information, certificate, statement or report not misleading.

SECTION 3.1   Master Servicer to Service Mortgage Loans.

For and on behalf of the Certificateholders, the Master Servicer shall service and administer the Mortgage Loans in accordance with the terms of (i)   the Servicing Rights Transfer and Subservicing Agreement, pursuant to which First Tennessee Mortgage Services, Inc. engaged the Master Servicer to subservice the Mortgage Loans, (ii) this Agreement and (iii) the customary and usual standards of practice of prudent mortgage loan servicers; provided that if there is a conflict between the terms of the Servicing Agreement and the Servicing Rights Transfer and Subservicing Agreement, on the one hand, and this Agreement, on the other hand, the terms of this Agreement shall prevail. In connection with such servicing and administration, the Master Servicer shall have full power and authority, acting alone and/or through Subservicers as provided in Section 3.2 hereof, to do or cause to be done any and all things that it may deem necessary or desirable in connection with such servicing and administration, including but not limited to, the power and authority, subject to the terms hereof (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages (but only in the manner provided in this Agreement), (iii) to collect any Insurance Proceeds and other Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan; provided that the Master Servicer shall not take any action that is inconsistent with or prejudices the interests of the Trust Fund or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee and the Certificateholders under this Agreement. The Master Servicer shall represent and protect the interests of the Trust Fund in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan, and shall not make or permit any modification, waiver or amendment of any Mortgage Loan which would cause the REMIC created hereunder to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code. Without limiting the generality of the foregoing, the Master Servicer, in its own name or in the name of the Depositor and the Trustee, is hereby authorized and empowered by the Depositor and the Trustee, when the Master Servicer believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to the Mortgage Loans, and with respect to the Mortgaged Properties held for the benefit of the Certificateholders. The Master Servicer shall prepare and deliver to the Depositor and/or the Trustee such documents requiring execution and delivery by either or both of them as are necessary or appropriate to enable the Master Servicer to service and administer the Mortgage Loans to the extent that the Master Servicer is not permitted to execute and deliver such documents pursuant to the preceding sentence. Upon receipt of such documents, the Depositor and/or the Trustee shall execute such documents and deliver them to the Master Servicer. The Master Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of the Subservicer, when the Master Servicer or the Subservicer as the case may be, believes it appropriate in its best judgment to register any Mortgage Loan on the MERS® System, or cause the removal from the registration of any Mortgage Loan on the MERS® System, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns.

In accordance with the standards of the preceding paragraph, the Master Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties, which advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.6, and further as provided in Section 3.8. The costs incurred by the Master Servicer, if any, in effecting the timely payments of taxes and assessments on the Mortgaged Properties and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balances of the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

SECTION 3.2   Subservicing; Enforcement of the Obligations of Servicers.

(a)   The Master Servicer may arrange for the subservicing of any Mortgage Loan by a Subservicer pursuant to a subservicing agreement; provided, however, that such subservicing arrangement and the terms of the related subservicing agreement must provide for the servicing of such Mortgage Loans in a manner consistent with the servicing arrangements contemplated hereunder. Unless the context otherwise requires, references in this Agreement to actions taken or to be taken by the Master Servicer in servicing the Mortgage Loans include actions taken or to be taken by a Subservicer on behalf of the Master Servicer. Notwithstanding the provisions of any subservicing agreement, any of the provisions of this Agreement relating to agreements or arrangements between the Master Servicer and a Subservicer or reference to actions taken through a Subservicer or otherwise, the Master Servicer shall remain obligated and liable to the Depositor, the Trustee and the Certificateholders for the servicing and administration of the Mortgage Loans in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such subservicing agreements or arrangements or by virtue of indemnification from the Subservicer and to the same extent and under the same terms and conditions as if the Master Servicer alone were servicing and administering the Mortgage Loans. All actions of each Subservicer performed pursuant to the related subservicing agreement shall be performed as an agent of the Master Servicer with the same force and effect as if performed directly by the Master Servicer.

(b)   For purposes of this Agreement, the Master Servicer shall be deemed to have received any collections, recoveries or payments with respect to the Mortgage Loans that are received by a Subservicer regardless of whether such payments are remitted by the Subservicer to the Master Servicer.

SECTION 3.3   Rights of the Depositor and the Trustee in Respect of the Master Servicer.

The Depositor may, but is not obligated to, enforce the obligations of the Master Servicer hereunder and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of the Master Servicer hereunder and in connection with any such defaulted obligation to exercise the related rights of the Master Servicer hereunder; provided that the Master Servicer shall not be relieved of any of its obligations hereunder by virtue of such performance by the Depositor or its designee. Neither the Trustee nor the Depositor shall have any responsibility or liability for any action or failure to act by the Master Servicer nor shall the Trustee or the Depositor be obligated to supervise the performance of the Master Servicer hereunder or otherwise.

SECTION 3.4   Trustee to Act as Master Servicer.

In the event that the Master Servicer shall for any reason no longer be the Master Servicer hereunder (including by reason of an Event of Default), the Trustee or its successor shall thereupon assume all of the rights and obligations of the Master Servicer hereunder arising thereafter (except that the Trustee shall not be (i) liable for losses of the Master Servicer pursuant to Section 3.9 hereof or any acts or omissions of the predecessor Master Servicer hereunder), (ii) obligated to make Advances if it is prohibited from doing so by applicable law, (iii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder including, but not limited to, repurchases or substitutions of Mortgage Loans pursuant to Section 2.2 or 2.3 hereof, (iv) responsible for expenses of the Master Servicer pursuant to Section 2.3 or (v) deemed to have made any representations and warranties of the Master Servicer hereunder). Any such assumption shall be subject to Section 7.2 hereof. If the Master Servicer shall for any reason no longer be the Master Servicer (including by reason of any Event of Default), the Trustee or its successor shall succeed to any rights and obligations of the Master Servicer under each subservicing agreement.

The Master Servicer shall, upon request of the Trustee, but at the expense of the Master Servicer, deliver to the assuming party all documents and records relating to each subservicing agreement or substitute subservicing agreement and the Mortgage Loans then being serviced thereunder and an accounting of amounts collected or held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the substitute subservicing agreement to the assuming party.

SECTION 3.5   Collection of Mortgage Loan Payments; Certificate Account; Distribution Account.

(a)   The Master Servicer shall make reasonable efforts in accordance with the customary and usual standards of practice of prudent mortgage servicers to collect all payments called for under the terms and provisions of the Mortgage Loans to the extent such procedures shall be consistent with this Agreement and the terms and provisions of any related Required Insurance Policy. Consistent with the foregoing, the Master Servicer may in its discretion (i) waive any late payment charge or any prepayment charge or penalty interest in connection with the prepayment of a Mortgage Loan and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 180 days; provided, however, that the Master Servicer cannot extend the maturity of any such Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any such arrangement, the Master Servicer shall make Advances on the related Mortgage Loan in accordance with the provisions of Section 4.1 during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements. The Master Servicer shall not be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law.

(b)   The Master Servicer shall establish and maintain the Certificate Account into which the Master Servicer shall deposit or cause to be deposited no later than two (2) Business Days after receipt, except as otherwise specifically provided herein, the following payments and collections remitted by Subservicers or received by it in respect of the Mortgage Loans subsequent to the Cut-off Date (other than in respect of principal and interest due on the Mortgage Loans on or before the Cut-off Date) and the following amounts required to be deposited hereunder:

(i)   all payments on account of principal on the Mortgage Loans, including Principal Prepayments;

(ii)   all payments on account of interest on the Mortgage Loans, net of the related Master Servicing Fee and any Prepayment Interest Excess;

(iii)   all Insurance Proceeds and Liquidation Proceeds in respect of the related Mortgage Loans, other than proceeds to be applied to the restoration or repair of the Mortgaged Property or released to the Mortgagor in accordance with the Master Servicer’s normal servicing procedures;

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

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

(vi)   any Substitution Adjustment Amounts or the Purchase Price for any Deleted Mortgage Loan;

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

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

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

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

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

(i)   the aggregate amount remitted by the Master Servicer to the Trustee pursuant to Section 3.8(a)(ix);

(ii)   any amount deposited by the Master Servicer pursuant to this Section 3.5(c) in connection with any losses on Permitted Investments; and

(iii)   any other amounts deposited hereunder which are required to be deposited in the Distribution Account.

In the event that the Master Servicer shall remit any amount not required to be remitted, it may at any time direct the Trustee to withdraw such amount from the Distribution Account, any provision herein to the contrary notwithstanding. Such direction may be accomplished by delivering an Officer’s Certificate to the Trustee which describes the amounts deposited in error in the Distribution Account. All funds deposited in the Distribution Account shall be held by the Trustee in trust for the Certificateholders until disbursed in accordance with this Agreement or withdrawn in accordance with Section 3.8. In no event shall the Trustee incur liability for withdrawals from the Distribution Account at the direction of the Master Servicer.

(iv)   The institution at which the Certificate Account is maintained shall invest funds as directed by the Master Servicer in Permitted Investments which shall mature not later than the second Business Day next preceding the related Distribution Account Deposit Date (except that if such Permitted Investment is an obligation of the institution that maintains such account, then such Permitted Investment shall mature not later than the Business Day next preceding such Distribution Account Deposit Date) and, shall not be sold or disposed of prior to its maturity. If the Master Servicer does not provide such prior written investment direction, the funds in the Certificate Account will be held uninvested. All such Permitted Investments shall be made in the name of the Trustee, for the benefit of the Certificateholders. All income and gain net of any losses realized from any such investment of funds on deposit in the Certificate Account shall be for the benefit of the Master Servicer as servicing compensation. The amount of any losses in the Certificate Account in respect of any such investments shall promptly be deposited by the Master Servicer in the Certificate Account. The funds in the Distribution Account shall be held uninvested. The Trustee in its fiduciary capacity shall not be liable for the amount of any loss incurred in respect of any investment or lack of investment of funds held in the Certificate Account or the Distribution Account and made in accordance with this Section 3.5.

(v)   The Master Servicer shall give notice to the Trustee, the Seller, each Rating Agency and the Depositor of any proposed change of the location of the Certificate Account prior to any change thereof. The Trustee shall give notice to the Master Servicer, the Seller, each Rating Agency and the Depositor of any proposed change of the location of the Distribution Account prior to any change thereof.

SECTION 3.6   Collection of Taxes, Assessments and Similar Items; Escrow Accounts.

(a)   To the extent required by the related Mortgage Note and not violative of current law, the Master Servicer shall establish and maintain one or more accounts (each, an “Escrow Account”) and deposit and retain therein all collections from the Mortgagors (or advances by the Master Servicer) for the payment of taxes, assessments, hazard insurance premiums or comparable items for the account of the Mortgagors. Nothing herein shall require the Master Servicer to compel a Mortgagor to establish an Escrow Account in violation of applicable law.

(b)   Withdrawals of amounts so collected from the Escrow Accounts may be made only to effect timely payment of taxes, assessments, hazard insurance premiums, condominium or PUD association dues, or comparable items, to reimburse the Master Servicer out of related collections for any payments made pursuant to Sections 3.1 hereof (with respect to taxes and assessments and insurance premiums) and 3.9 hereof (with respect to hazard insurance), to refund to any Mortgagors any sums determined to be overages, to pay interest, if required by law or the terms of the related Mortgage or Mortgage Note, to Mortgagors on balances in the Escrow Account or to clear and terminate the Escrow Account at the termination of this Agreement in accordance with Section 9.1 hereof. The Escrow Accounts shall not be a part of the Trust Fund.

(c)   The Master Servicer shall advance any payments referred to in Section 3.6(a) that are not timely paid by the Mortgagors on the date when the tax, premium or other cost for which such payment is intended is due, but the Master Servicer shall be required so to advance only to the extent that such advances, in the good faith judgment of the Master Servicer, will be recoverable by the Master Servicer out of Insurance Proceeds, Liquidation Proceeds or otherwise.

SECTION 3.7   Access to Certain Documentation and Information Regarding the Mortgage Loans.

The Master Servicer shall afford the Depositor and the Trustee reasonable access to all records and documentation regarding the Mortgage Loans and all accounts, insurance information and other matters relating to this Agreement, such access being afforded without charge, but only upon reasonable request and during normal business hours at the office designated by the Master Servicer.

Upon reasonable advance notice in writing, the Master Servicer will provide to each Certificateholder or Certificate Owner which is a savings and loan association, bank or insurance company certain reports and reasonable access to information and documentation regarding the Mortgage Loans sufficient to permit such Certificateholder or Certificate Owner to comply with applicable regulations of the OTS or other regulatory authorities with respect to investment in the Certificates; provided that the Master Servicer shall be entitled to be reimbursed by each such Certificateholder or Certificate Owner for actual expenses incurred by the Master Servicer in providing such reports and access.

SECTION 3.8   Permitted Withdrawals from the Certificate Account and Distribution Account.

(a)   The Master Servicer may from time to time, or shall (in the case of Section 3.8(a)(ix)), make withdrawals from the Certificate Account for the following purposes:

(i)   to the extent not previously retained by the Master Servicer, to pay to the Master Servicer the master servicing compensation to which it is entitled pursuant to Section 3.14, and earnings on or investment income with respect to funds in or credited to the Certificate Account as additional master servicing compensation;

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

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

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

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

(vi)   to pay to the Seller or Master Servicer, as applicable, with respect to each Mortgage Loan or property acquired in respect thereof that has been purchased pursuant to Section 2.2, 2.3 or 3.11, all amounts received thereon after the date of such purchase;

(vii)   to reimburse the Seller, the Master Servicer or the Depositor for expenses incurred by any of them and reimbursable pursuant to Section 6.3 hereof;

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

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

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

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

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

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

(ii)   to withdraw and return to the Master Servicer any amount deposited in the Distribution Account and not required to be deposited therein; and

(iii)   to clear and terminate the Distribution Account upon termination of the Agreement pursuant to Section 9.1 hereof.

SECTION 3.9   Maintenance of Hazard Insurance; Maintenance of Primary Insurance Policies.

(a)   The Master Servicer shall cause to be maintained, for each Mortgage Loan, hazard insurance with extended coverage in an amount that is at least equal to the lesser of (i) the maximum insurable value of the improvements securing such Mortgage Loan or (ii) the greater of (y) the outstanding principal balance of the Mortgage Loan and (z) an amount such that the proceeds of such policy shall be sufficient to prevent the Mortgagor and/or the mortgagee from becoming a co-insurer. Each such policy of standard hazard insurance shall contain, or have an accompanying endorsement that contains, a standard mortgagee clause. Any amounts collected by the Master Servicer under any such policies (other than the amounts to be applied to the restoration or repair of the related Mortgaged Property or amounts released to the Mortgagor in accordance with the Master Servicer’s normal servicing procedures) shall be deposited in the Certificate Account. Any cost incurred by the Master Servicer in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trustee for their benefit, be added to the principal balance of the Mortgage Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs shall be recoverable by the Master Servicer out of late payments by the related Mortgagor or out of Liquidation Proceeds to the extent permitted by Section 3.8 hereof. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor or maintained on property acquired in respect of a Mortgage other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If the Mortgaged Property is located at the time of origination of the Mortgage Loan in a federally designated special flood hazard area and such area is participating in the national flood insurance program, the Master Servicer shall cause flood insurance to be maintained with respect to such Mortgage Loan. Such flood insurance shall be in an amount equal to the least of (i) the original principal balance of the related Mortgage Loan, (ii) the replacement value of the improvements which are part of such Mortgaged Property, and (iii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program.

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

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

The Master Servicer shall not be required to maintain any Primary Insurance Policy (i) with respect to any Mortgage Loan with a Loan-to-Value Ratio less than or equal to 80% as of any date of determination or, based on a new appraisal, the principal balance of such Mortgage Loan represents 80% or less of the new appraised value or (ii) if maintaining such Primary Insurance Policy is prohibited by applicable law.

The Master Servicer agrees to effect the timely payment of the premiums on each Primary Insurance Policy, and such costs not otherwise recoverable shall be recoverable by the Master Servicer from the related liquidation proceeds.

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

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

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

(b)   Subject to the Master Servicer’s duty to enforce any due-on-sale clause to the extent set forth in Section 3.10(a) hereof, in any case in which a Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage that requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the Mortgage Loan, the Master Servicer shall prepare and deliver or cause to be prepared and delivered to the Trustee for signature and shall direct, in writing, the Trustee to execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person. In connection with any such assumption, no material term of the Mortgage Note may be changed. In addition, the substitute Mortgagor and the Mortgaged Property must be acceptable to the Master Servicer in accordance with its underwriting standards as then in effect. Together with each such substitution, assumption or other agreement or instrument delivered to the Trustee for execution by it, the Master Servicer shall deliver an Officer’s Certificate signed by a Servicing Officer stating that the requirements of this subsection have been met in connection therewith. The Master Servicer shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the Trustee the original of such substitution or assumption agreement, which in the case of the original shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Any fee collected by the Master Servicer for entering into an assumption or substitution of liability agreement will be retained by the Master Servicer as additional servicing compensation.

SECTION 3.11   Realization Upon Defaulted Mortgage Loans; Repurchase of Certain Mortgage Loans.

The Master Servicer shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. In connection with such foreclosure or other conversion, the Master Servicer shall follow such practices and procedures as it shall deem necessary or advisable and as shall be normal and usual in its general mortgage servicing activities and meet the requirements of the insurer under any Required Insurance Policy; provided, however, that the Master Servicer shall not be required to expend its own funds in connection with any foreclosure or towards the restoration of any property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the Mortgage Loan after reimbursement to itself of such expenses and (ii) that such expenses will be recoverable to it through Liquidation Proceeds (respecting which it shall have priority for purposes of withdrawals from the Certificate Account). The Master Servicer shall be responsible for all other costs and expenses incurred by it in any such proceedings; provided, however, that it shall be entitled to reimbursement thereof from the liquidation proceeds with respect to the related Mortgaged Property, as provided in the definition of Liquidation Proceeds. If the Master Servicer has knowledge that a Mortgaged Property which the Master Servicer is contemplating acquiring in foreclosure or by deed in lieu of foreclosure is located within a 1 mile radius of any site listed in the Expenditure Plan for the Hazardous Substance Clean Up Bond Act of 1984 or other site with environmental or hazardous waste risks known to the Master Servicer, the Master Servicer will, prior to acquiring the Mortgaged Property, consider such risks and only take action in accordance with its established environmental review procedures.

With respect to any REO Property, the deed or certificate of sale shall be taken in the name of the Trust Fund for the benefit of the Certificateholders, or its nominee, on behalf of the Certificateholders. The Master Servicer shall ensure that the title to such REO Property references the Pooling and Servicing Agreement and the Trust Fund’s capacity thereunder. Pursuant to its efforts to sell such REO Property, the Master Servicer shall either itself or through an agent selected by the Master Servicer protect and conserve such REO Property in the same manner and to such extent as is customary in the locality where such REO Property is located. The Master Servicer shall perform the tax reporting and withholding required by Sections 1445 and 6050J of the Code with respect to foreclosures and abandonments, the tax reporting required by Section 6050H of the Code with respect to the receipt of mortgage interest from individuals and any tax reporting required by Section 6050P of the Code with respect to the cancellation of indebtedness by certain financial entities, by preparing such tax and information returns as may be required, in the form required, and delivering the same to the Trustee for filing.

In the event that the Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property prior to the close of the third taxable year after the taxable year of its acquisition by the Trust Fund unless the Trustee shall have been supplied with an Opinion of Counsel to the effect that the holding by the Trust Fund of such Mortgaged Property subsequent to such three-year period will not result in the imposition of taxes on “prohibited transactions” of the REMIC created hereunder as defined in Section 860F of the Code or cause the REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding, in which case the Trust Fund may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel). Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or (ii) subject the REMIC created hereunder to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the Master Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

In the event of a default on a Mortgage Loan one or more of whose obligor is not a United States Person, as that term is defined in Section 7701(a)(30) of the Code, in connection with any foreclosure or acquisition of a deed in lieu of foreclosure (together, “foreclosure”) in respect of such Mortgage Loan, the Master Servicer will cause compliance with the provisions of Treasury Regulation Section 1.1445-2(d)(3) (or any successor thereto) necessary to assure that no withholding tax obligation arises with respect to the proceeds of such foreclosure except to the extent, if any, that proceeds of such foreclosure are required to be remitted to the obligors on such Mortgage Loan.

The decision of the Master Servicer to foreclose on a defaulted Mortgage Loan shall be subject to a determination by the Master Servicer that the proceeds of such foreclosure would exceed the costs and expenses of bringing such a proceeding. The income earned from the management of any REO Properties, net of reimbursement to the Master Servicer for expenses incurred (including any property or other taxes) in connection with such management and net of unreimbursed Master Servicing Fees, Advances and Servicing Advances, shall be applied to the payment of principal of and interest on the related defaulted Mortgage Loans (with interest accruing as though such Mortgage Loans were still current) and all such income shall be deemed, for all purposes in this Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the Certificate Account. To the extent the net income received during any calendar month is in excess of the amount attributable to amortizing principal and accrued interest at the related Mortgage Rate on the related Mortgage Loan for such calendar month, such excess shall be considered to be a partial prepayment of principal of the related Mortgage Loan.

The proceeds from any liquidation of a Mortgage Loan, as well as any income from an REO Property, will be applied in the following order of priority: first, to reimburse the Master Servicer for any related unreimbursed Servicing Advances and Master Servicing Fees; second, to reimburse the Master Servicer for any unreimbursed Advances; third, to reimburse the Certificate Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by the Master Servicer pursuant to Section 3.8(a)(iii) that related to such Mortgage Loan; fourth, to accrued and unpaid interest (to the extent no Advance has been made for such amount or any such Advance has been reimbursed) on the Mortgage Loan or related REO Property, at the Adjusted Net Mortgage Rate to the Due Date occurring in the month in which such amounts are required to be distributed; and fifth, as a recovery of principal of the Mortgage Loan. Excess Proceeds, if any, from the liquidation of a Liquidated Mortgage Loan will be retained by the Master Servicer as additional servicing compensation pursuant to Section 3.14.

The Master Servicer, with the consent of the Trustee, shall have the right to purchase for its own account from the Trust Fund any Mortgage Loan which is 91 days or more delinquent at a price equal to the Purchase Price. The Purchase Price for any Mortgage Loan purchased hereunder shall be deposited in the Certificate Account and the Trustee, upon receipt of a certificate from the Master Servicer in the form of Exhibit M hereto, shall release or cause to be released to the purchaser of such Mortgage Loan the related Mortgage File and shall execute and deliver such instruments of transfer or assignment prepared by the purchaser of such Mortgage Loan, in each case without recourse, as shall be necessary to vest in the purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto and the purchaser of such Mortgage Loan shall succeed to all the Trustee’s right, title and interest in and to such Mortgage Loan and all security and documents related thereto. Such assignment shall be an assignment outright and not for security. The purchaser of such Mortgage Loan shall thereupon own such Mortgage Loan, and all security and documents, free of any further obligation to the Trustee or the Certificateholders with respect thereto.

SECTION 3.12   Trustee to Cooperate; Release of Mortgage Files.

Upon the payment in full of any Mortgage Loan, or the receipt by the Master Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, the Master Servicer will immediately notify the Trustee by delivering, or causing to be delivered a “Request for Release” substantially in the form of Exhibit M. Upon receipt of such request, the Trustee shall or shall cause the Custodian to promptly release the related Mortgage File to the Master Servicer, and the Trustee shall at the Master Servicer’s direction execute and deliver to the Master Servicer the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage in each case provided by the Master Servicer, together with the Mortgage Note with written evidence of cancellation thereon. Expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the related Mortgagor. From time to time and as shall be appropriate for the servicing or foreclosure of any Mortgage Loan, including for such purpose, collection under any policy of flood insurance, any fidelity bond or errors or omissions policy, or for the purposes of effecting a partial release of any Mortgaged Property from the lien of the Mortgage or the making of any corrections to the Mortgage Note or the Mortgage or any of the other documents included in the Mortgage File, the Trustee shall, upon delivery to the Trustee of a Request for Release in the form of Exhibit L signed by a Servicing Officer, release the Mortgage File to the Master Servicer. Subject to the further limitations set forth below, the Master Servicer shall cause the Mortgage File or documents so released to be returned to the Trustee or its Custodian when the need therefor by the Master Servicer no longer exists, unless the Mortgage Loan is liquidated and the proceeds thereof are deposited in the Certificate Account, in which case the Master Servicer shall deliver to the Trustee a Request for Release in the form of Exhibit M, signed by a Servicing Officer.

If the Master Servicer at any time seeks to initiate a foreclosure proceeding in respect of any Mortgaged Property as authorized by this Agreement, the Master Servicer shall deliver or cause to be delivered to the Trustee, for signature, as appropriate, any court pleadings, requests for trustee’s sale or other documents necessary to effectuate such foreclosure or any legal action brought to obtain judgment against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce any other remedies or rights provided by the Mortgage Note or the Mortgage or otherwise available at law or in equity.

SECTION 3.13   Documents Records and Funds in Possession of Master Servicer to be Held for the Trustee.

Notwithstanding any other provisions of this Agreement, the Master Servicer shall transmit to the Trustee as required by this Agreement all documents and instruments in respect of a Mortgage Loan coming into the possession of the Master Servicer from time to time and shall account fully to the Trustee for any funds received by the Master Servicer or which otherwise are collected by the Master Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan. All Mortgage Files and funds collected or held by, or under the contr
