	(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

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 2007-FA4, 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 Underwriters, 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 any 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.

		SECTION 2.6 Execution and Delivery of Certificates.

The Trustee acknowledges the transfer and assignment to it of the Trust Fund and, concurrently with such transfer and assignment, has executed and delivered to or upon the order

of the Depositor, the Certificates in authorized denominations evidencing directly or indirectly the entire ownership of the Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the rights referred to above for the benefit of all present and future Holders of the Certificates and to perform the duties set forth in this Agreement to the best of its ability, to the end that the interests of the Holders of the Certificates may be adequately and effectively protected.

SECTION 2.7 REMIC Matters.

The Preliminary Statement sets forth the “latest possible maturity date” for federal income tax purposes of all REMIC regular interests created hereby.

The assets of the Lower REMIC shall be as set forth in the definition thereof. Each interest identified in the first table below by a designation beginning with “L” shall be a “regular interest” in the Lower REMIC and a Lower REMIC Interest, and the RL Interest shall be the sole class of residual interest in the Lower REMIC. The Lower REMIC Interests shall be uncertificated and shall be held by the Trustee as assets of the Middle REMIC.

The assets of the Middle REMIC shall be as set forth in the definition thereof. Each interest identified in the second table below by a designation beginning with “M” shall be a “regular interest” in the Middle REMIC and a Middle REMIC Interest, and the RM Interest shall be the sole class of residual interest in the Middle REMIC. The Middle REMIC Interests shall be uncertificated and shall be held by the Trustee as assets of the Upper REMIC.

The assets of the Upper REMIC shall be as set forth in the definition thereof. The “regular interests” in the Upper REMIC are represented by the Regular Certificates. The Class I-A-1 Certificates shall also represent the right to receive the Class I-A-1 Yield Supplement Amount, which shall not be a part of any REMIC hereunder but shall constitute contractual rights coupled with a regular interest within the meaning of Treasury regulations section 1.860G -2(i). The Class I-A-6 Certificates shall also represent the right to receive the Class I-A-6 Yield Supplement Amount, which shall not be a part of any REMIC hereunder but shall constitute contractual rights coupled with a regular interest within the meaning of Treasury regulations section 1.860G -2(i). The RU Interest shall be the sole class of residual interest in the Upper REMIC. The Class I-A-R Certificate shall represent ownership of the RL Interest, RM Interest and RU Interest.

The “Startup Day” for purposes of the REMIC Provisions for each REMIC hereunder shall be the Closing Date. The Tax Matters Person with respect to each REMIC hereunder shall be the Trustee and the Trustee shall hold the Tax Matters Person Certificate. Each REMIC’s taxable year shall be the calendar year and its accounts shall be maintained using the accrual method.

(1) The Lower REMIC Interest L-I-A-1, Lower REMIC Interest L-I-A-2 and Lower REMIC Interest L-I-ZZZ shall be Corresponding Classes to these classes of Middle REMIC Interests: M-I-A-1, X-X-X-0, X-X-X-0, X-X-X-0, X-X-X-0, X-X-X-0, X-X-X-0, M-I-A-10, M-I-A-11, M-I-A-13, X-X-X-00, X-X-X-XX, X-X-0, X-X-0, X-X-0, X-X-0, M-B-5 and M-B-6 (provided that with respect to X-X-0, X-X-0, X-X-0, X-X-0, X-X-0 and M-B-6, such Lower REMIC Interests shall only correspond to the portion supported by Pool I). The Lower REMIC Interest L-I-PO corresponds to the Middle REMIC Interest M-I-PO. The Lower REMIC Interest L-II-A-1, Lower REMIC L-II-A-2 and Lower REMIC Interest L-II-ZZZ shall be Corresponding Classes to these classes of Middle REMIC Interests: M-II-A-1, X-X-0, X-X-0, X-X-0, X-X-0, X-X-0 and M-B-6 (provided that with respect to X-X-0, X-X-0, X-X-0, X-X-0, X-X-0 and M-B-6, such Lower REMIC Interests shall only correspond to the portion supported by Pool II). The Lower REMIC Interest L-II-PO corresponds to the Middle REMIC Interest M-II-PO.

“L1 Interests” refers to the L-I-A-1 Lower REMIC Interest and the L-II-A-1 Lower REMIC Interest. “L2 Interests” refers to the L-I-A-2 Lower REMIC Interest and the L-II-A-2 Lower REMIC Interest. “LZZZ Interests” refers to L-I-ZZZ Lower REMIC Interest and L-II-ZZZ Lower REMIC Interest. “LPO Interests” refer to the L-I-PO Lower REMIC Interest and the L-II-PO Lower REMIC Interest. Each L1 Interest shall have a principal balance initially equal to 0.9% of the Group Subordinate Amount of its corresponding Mortgage Pool. Each L2 Interest shall have a principal balance initially equal to 0.1% of the Group Subordinate Amount of its corresponding Mortgage Pool. The initial principal balance of each LZZZ Interest shall equal the excess of the Pool Principal Balance of its corresponding Mortgage Pool over the sum of (i) the initial principal balances of the L1 Interests and L2 Interests corresponding to such Mortgage Pool, and (ii) the portion of the LPO Interest attributable to the Discount Mortgage Loans in the Mortgage Pool corresponding to such LZZZ Interest.

Unless a Cross-over Situation (as defined below) exists, principal and Realized Losses arising with respect to each Mortgage Pool shall be allocated first to cause the L1 and L2

Interests corresponding to such Mortgage Pool to equal 0.9% and 0.1% of the Group Subordinate Amount of such Mortgage Pool as of such Distribution Date (after distributions of principal and allocation of Realized Losses are made) and all excess principal and Realized Losses shall be allocated to the LZZZ Interest corresponding to such Mortgage Pool. A L1, L2 or LZZZ Interest that is allocated principal on any Distribution Date shall receive such principal, and have its principal balance reduced by the amount of such principal, on such Distribution Date. Similarly, a L1, L2 or LZZZ Interest that is allocated a Realized Loss on any Distribution Date shall have its principal balance reduced by the amount of such Realized Loss on such Distribution Date.

A “Cross-over Situation” exists if on any Distribution Date (after taking into account distributions of principal and allocations of Realized Losses on such Distribution Date) the L1 and L2 Interests corresponding to any Mortgage Pool are in the aggregate less than 1% of the Group Subordinate Amount of the corresponding Mortgage Pool. If a Cross-over Situation exists on any Distribution Date, and the weighted average interest rate of the outstanding L1 and L2 Interests is less than the Pass-Through Rate for any Class of Subordinate Certificates for the following Distribution Date, a Principal Reallocation Payment (as defined below) shall be made proportionately to the outstanding L1 Interests prior to any other distributions of principal from each such Mortgage Pool so that the Calculation Rate equals the Pass-Through Rate for each Class of Subordinate Certificates. If a Cross-over Situation exists on any Distribution Date, and the weighted average rate of the outstanding L1 and L2 Interests is greater than the Pass-Through Rate for any Class of Subordinate Certificates for the following Distribution Date, a Principal Reallocation Payment shall be made proportionately to the outstanding L2 Interests prior to any other distributions of principal from each such Mortgage Pool so that the Calculation Rate equals the Pass-Through Rate for each Class of Subordinate Certificates. A “Principal Reallocation Payment” is a distribution of the minimum amount of principal that causes the Calculation Rate (as defined below) with respect to the outstanding L1 and L2 Interests to equal the Pass-Through Rate for each Class of Subordinate Certificates. The “Calculation Rate” shall equal the product of (i) 10 and (ii) the weighted average interest rate of the outstanding L1 and L2 Interests, treating each L1 Interest as capped at zero or reduced by a fixed percentage of 100% of the interest accruing on such class. Principal Reallocation Payments shall be made from principal received on the Mortgage Loans from a Mortgage Pool and shall also consist of a proportionate allocation of Realized Losses from the Mortgage Loans of a Mortgage Pool. For purposes of making Principal Reallocation Payments, to the extent that the principal received during the applicable collection period from the related Mortgage Pool or Mortgage Pools and related Realized Losses are insufficient to make the necessary reduction of principal, then interest shall accrue on the LZZZ Interest (and be added to its principal balance) of the related Mortgage Pool or Mortgage Pools to allow the necessary Principal Reallocation Payment to be made. The Calculation Rate is designed to always equal the Pass-Through Rate of each Class of Subordinated Certificates.

If a Cross-over Situation exists, the aggregate principal balances of the outstanding L1 and L2 Interests of all of the Mortgage Pools shall not be reduced below one percent of the aggregate Pool Principal Balance of all of the Mortgage Pools for the following Distribution Date in excess of the Senior Certificates as of the related Distribution Date (after taking into account distributions of principal and allocations of Realized Losses on such Distribution Date). To the extent this limitation prevents the distribution of principal to the L1 and L2 Interests of a Mortgage Pool and the related LZZZ Interest has already been reduced to zero, such excess

principal from such Mortgage Pool shall be paid proportionately to the LZZZ Interests of the Mortgage Pool or Mortgage Pools whose aggregate L1 and L2 Interests are less than one percent of the related Group Subordinate Amount. Any such shortfall as a result of the Mortgage Pool or Mortgage Pools receiving the extra payment having a Designated Mortgage Pool Rate (as defined below) lower than the Designated Mortgage Pool Rate of the Mortgage Pool or Mortgage Pools from which the payment was reallocated shall be treated as a Realized Loss and if excess arises as a result of the Mortgage Pool receiving the extra payment having a Designated Mortgage Pool Rate higher than the Mortgage Pool from which the payment was reallocated it shall reimburse the Middle REMIC for prior Realized Losses.

The Pass-Through Rate on each Class of Subordinated Certificates is variable and will be equal to the weighted average of the Middle REMIC Interest Rates on Middle REMIC Interest M-B-1, Middle REMIC Interest M-B-2, Middle REMIC Interest M-B-3, Middle REMIC Interest M-B-4, Middle REMIC Interest M-B-5, Middle REMIC Interest M-B-6, weighted on the basis of the principal balance of each such Middle REMIC Interest.

On each Distribution Date Available Funds shall be distributed with respect to the Middle REMIC Interests in a manner such that:

	(a)	interest accrued, if any, on each Middle REMIC Interest is distributed with respect to each such Middle REMIC Interest in the same manner that Accrued Certificate Interest is distributed with respect to the Corresponding Class or Classes of Certificates pursuant to Section 4.2; and

	(b)	principal is distributed (and Realized Losses shall be allocated) with respect to each such Middle REMIC Interest in the same manner that principal is distributed (and Realized Losses is allocated) with respect to the Corresponding Class or Classes of Certificates pursuant to Section 4.2 and Section 4.4.

The Class L-I-PO Interest shall be entitled to receive the Class PO Principal Distribution Amount for Pool I.

The Class L-II-PO Interest shall be entitled to receive the Class PO Principal Distribution Amount for Pool II.

The foregoing REMIC structure is intended to cause all of the cash from the Mortgage Loans to flow through to the Upper REMIC as cash flow on a REMIC regular interest, without creating any shortfall-actual or potential (other than for credit losses) to any REMIC regular interest. To the extent that the structure is believed to diverge from such intention the Trustee shall resolve ambiguities to accomplish such result and shall to the extent necessary rectify any drafting errors or seek clarification to the structure without Certificateholder approval (but with guidance of counsel) to accomplish such intention.

SECTION 2.8 Covenants of the Master Servicer.

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.

ARTICLE III

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

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 any 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. The Certificate Account shall consist of two separate subaccounts, each of which shall relate to a particular Mortgage Pool. The Master Servicer shall deposit or cause to be deposited into the appropriate subaccount of the Certificate Account no later than two 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 in the related Mortgage Pool, including Principal Prepayments;

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

	(iii)	all Insurance Proceeds and Liquidation Proceeds in respect of the related Mortgage Loans in the related Mortgage Pool, 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 in respect of the related Mortgage Pool 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 in respect of the related Mortgage Pool pursuant to Sections 3.9(b) and 3.9(d);

	(vi)	any Substitution Amounts or the Purchase Price for any Deleted Mortgage Loan in the related Mortgage Pool;

	(vii)	all Advances in respect of the related Mortgage Pool made by the Master Servicer pursuAdjustmentant to Section 4.1; and

	(viii)	any other amounts required to be deposited hereunder in respect of the related Mortgage Pool.

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 applicable subaccount of 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. The Distribution Account shall consist of two separate subaccounts, each of which shall relate to a particular Mortgage Pool. The Trustee shall, promptly upon receipt, deposit in the Distribution Account and retain therein the following:

	(i)	the aggregate amount remitted by the Master Servicer to the Trustee in respect of a Mortgage Pool 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 applicable subaccount of 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 related 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 applicable subaccount of the Certificate Account for the following purposes:

	(i)	to the extent not previously retained by the Master Servicer, to pay the Retained Yield to (a) First Horizon, in its individual capacity as Seller, or (b) a subsequent owner of such Retained Yield through Seller’s sale, assignment, or certification of its rights to such Retained Yield, and 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 in respect of the related Mortgage Pool, 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 in respect of the related Mortgage Pool;

	(iv)	to reimburse the Master Servicer for Insured Expenses from the related Insurance Proceeds in respect of the related Mortgage Pool;

	(v)	to reimburse the Master Servicer for (a) unreimbursed Servicing Advances in respect of the related Mortgage Pool, 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 in respect of the related Mortgage Pool 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 and on a Mortgage Pool-by-Mortgage Pool 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. The Master Servicer shall distribute the Retained Yield, if any, to (i) First Horizon, in its individual capacity as Seller, or (ii) a subsequent owner of the Retained Yield through Seller’s sale, assignment, or certification of its rights to such Retained Yield, on each Distribution Account Deposit Date during the term of this Agreement.

(b)	The Trustee shall withdraw funds from the applicable subaccount of the Distribution Account for distributions to the related 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 not to exceed the highest value placed by the insurer on the improvements securing such Mortgage Loan. The required coverage under any such hazard insurance policy will be equal to the lesser of (i) the aggregate principal amount of all liens against the related Mortgaged Property, including the proposed loan/line amount as long as it equals at least 80% of the value of the improvements/replacement cost of the structure,

		and (ii) the replacement cost of the insurable improvements securing such Mortgage Loan. 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 applicable subaccount of 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 applicable subaccount of 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 applicable subaccount of 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 any REMIC created hereunder as defined in Section 860F of the Code or cause any 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 any 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 applicable subaccount of 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 applicable subaccount of 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 applicable subaccount of 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 applicable subaccount of 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 control of, the Master Servicer in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, including but not limited to, any funds on deposit in the Certificate Account, shall be held by the Master Servicer for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. The Master Servicer also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the Certificate Account, Distribution Account or any Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, or assert by legal action or otherwise any claim or right of setoff against any Mortgage File or any funds collected on, or in connection with, a Mortgage Loan, except, however, that the Master Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Master Servicer under this Agreement.

SECTION 3.14 Master Servicing Compensation.

As compensation for its activities as Master Servicer hereunder and as a subservicer pursuant to the Servicing Rights Transfer and Subservicing Agreement, the Master Servicer shall be entitled to retain or withdraw from the Certificate Account an amount equal to the Master Servicing Fee for each Mortgage Loan, provided that the aggregate Master Servicing Fee with respect to any Distribution Date shall be reduced (i) by the amount of any Compensating Interest paid by the Master Servicer with respect to such Distribution Date, and (ii) with respect to the first Distribution Date, an amount equal to any amount to be deposited into the Distribution Account by the Depositor pursuant to Section 2.1(a) and not so deposited.

Additional servicing compensation in the form of (i) Excess Proceeds, Prepayment Interest Excess and all income and gain net of any losses realized from Permitted Investments and (ii) prepayment penalties, assumption fees and late payment charges in each case under the circumstances and in the manner set forth in the applicable Mortgage Note or Mortgage shall be retained by the Master Servicer to the extent not required to be deposited in the Certificate Account pursuant to Section 3.5 hereof. The Master Servicer shall be required to pay all expenses incurred by it in connection with its master servicing activities hereunder (including payment of any premiums for hazard insurance and any Primary Insurance Policy and maintenance of the other forms of insurance coverage required by this Agreement) and shall not be entitled to reimbursement therefor except as specifically provided in this Agreement.

SECTION 3.15 Access to Certain Documentation.

The Master Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders of Certificates or Certificate Owners and the examiners and supervisory agents of the OTS, the FDIC and such other authorities, access to the documentation regarding the Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such access shall be afforded without charge, but only upon reasonable and prior written request and during normal business hours at the offices designated by the Master Servicer. Nothing in this Section shall limit the obligation of the Master Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Master Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section.

SECTION 3.16 Annual Statement as to Compliance.

		SECTION 3.17 Errors and Omissions Insurance; Fidelity Bonds.

The Master Servicer shall for so long as it acts as master servicer under this Agreement, obtain and maintain in force (a) a policy or policies of insurance covering errors and omissions in the performance of its obligations as Master Servicer hereunder and (b) a fidelity bond in respect of its officers, employees and agents. Each such policy or policies and bond shall, together, comply with the requirements from time to time of FNMA or FHLMC for persons performing servicing for mortgage loans purchased by FNMA or FHLMC.

(b)	Amounts allocated to the Group I Senior Certificates pursuant to clause (1) of Section 4.2(a)(iii) above will be distributed sequentially, in the following order of priority:

	(i)	to the Class I-A-R Certificates, until the Class Certificate Balance thereof has been reduced to zero;

	(ii)	concurrently, to the Class I-A-4 and Class I-A-14 Certificates, pro rata, in an amount up to the NAS Principal Distribution Amount for such Distribution Date, until the respective Class Certificate Balances thereof have each been reduced to zero

	(vii)	concurrently, to the Class I-A-4 and Class I-A-14 Certificates, pro rata, the remaining Senior Optimal Principal Amount for Pool I for such Distribution Date without regard to the NAS Principal Distribution Amount for such Distribution Date, until the respective Class Certificate Balances thereof have each been reduced to zero.

(c)	Amounts allocated to the Group II Senior Certificates pursuant to clause (1) of Section 4.2(a)(iii) above will be distributed to the Class II-A-1 Certificates, until the Class Certificate Balance thereof has been reduced to zero.

(d)	On each Distribution Date, the Trustee shall distribute to the Holders of the Class I-A-R Certificates representing the RL Interest, the RM Interest and the RU Interest, any Available Funds remaining in the related REMIC created hereunder for such Distribution Date after application of all amounts described in clauses (a) through (c) and (e) of this Section 4.2. Any distributions pursuant to this subsection (d) shall not reduce the Class Certificate Balances of the Class I-A-R Certificates.

	(e)	On and after the Cross-Over Date, the amount distributable to the Senior Certificates of the related Certificate Group pursuant to Section 4.2(a)(iii) for the related Distribution Date shall be allocated among the related Classes of Senior Certificates (other than the Class PO Certificates), pro rata, on the basis of their respective Class Certificate Balances immediately prior to such Distribution Date, regardless of the priorities and amounts set forth in Sections 4.2(a) through (c) above.

	(f)	If on any Distribution Date (i) the Class Certificate Balance of any Class of Subordinated Certificates (other than the Class of Subordinated Certificates with the highest priority of distribution) for which the related Class Prepayment Distribution Trigger was satisfied on such Distribution Date is reduced to zero and (ii) amounts distributable to such Class or Classes of Subordinated Certificates pursuant to clauses (2), (3) and (5) of the applicable Subordinated Optimal Principal Amount remain undistributed on such Distribution Date after all amounts otherwise distributable on such date pursuant to clauses (v) through (x) of Section 4.2(a) have been distributed, such amounts, to the extent of such Class’ remaining Allocable Share, shall be distributed on such Distribution Date to the remaining Classes of Subordinated Certificates on a pro rata basis, subject to the priority of payments described in clauses (v) through (x) of Section 4.2(a).

	(g)	In the event that in any calendar month the Master Servicer recovers an amount, net of reimbursable expenses (an “Unanticipated Recovery”), in respect of principal of a Mortgage Loan which had previously been allocated as a Realized Loss to any Class of Certificates pursuant to Section 4.4, on the Distribution Date in the next succeeding calendar month, the Trustee shall withdraw the Unanticipated Recovery from the Distribution Account and sequentially increase, in order of payment priority, the Class Certificate Balance of each Class of Certificates to which such Realized Losses were previously allocated by the amount of such Unanticipated Recovery, but not to exceed the amount of Realized Losses previously allocated to such Class pursuant to Section 4.4, and shall distribute the amount of such Unanticipated Recovery in the order of payment priority described in Section 4.2(a) of this Agreement. Holders of any Class of Certificates for which the Class Certificate Balance has been increased by the amount of any Unanticipated Recovery will not be entitled to any payment in respect of Accrued Certificate Interest on the amount of any such increase for any Interest Accrual Period preceding the Distribution Date on which such increase occurs. When the Class Certificate Balance of a Class of Certificates has been reduced to zero, the Holders of such Class shall not be entitled to any share of an Unanticipated Recovery, and such Unanticipated Recovery shall be allocated among all outstanding Classes of Certificates entitled thereto in accordance with the preceding sentence, subject to the remainder of this subsection (g). In the event that (i) any Unanticipated Recovery remains undistributed in accordance with the preceding sentence or (ii) the amount of an Unanticipated Recovery exceeds the amount of the Realized Loss previously allocated to any outstanding Classes with respect to the related Mortgage Loan,

on the applicable Distribution Date the Trustee shall distribute such Unanticipated Recoveries in accordance with the priorities set forth in Section 4.2(a)(iii).

For purposes of the preceding paragraph, the share of an Unanticipated Recovery allocable to any Class of Certificates with respect to a Mortgage Loan shall be (i) with respect to the Class PO Certificates, based on the applicable PO Percentage of the principal portion of the Realized Loss previously allocated thereto with respect to such Mortgage Loan (or all Mortgage Loans for purposes of the next to last sentence of the preceding paragraph), and (ii) with respect to any other Class of Certificates, based on its pro rata share (in proportion to the Class Certificate Balances thereof with respect to such Distribution Date) of the applicable Non-PO Percentage of the principal portion of any such Realized Loss previously allocated with respect to such Mortgage Loan (or Loans); provided however, that (i) the share of an Unanticipated Recovery allocable to a Principal Only Certificate with respect to any Mortgage Loan (or Loans) shall be reduced by the applicable PO Percentage of the aggregate amount previously distributed to such Class in respect of such Mortgage Loan (or Loans) and (ii) the amount by which the distributions to the Class PO Certificates have been so reduced shall be distributed to the Classes of Certificates described in clause (ii) of the preceding paragraph in the same proportion as described in such clause (ii). For purposes of the preceding sentence, any Class PO Deferred Amount distributable to a Principal Only Certificate on previous Distribution Dates shall be deemed to have been allocated in respect of the Mortgage Loans as to which the applicable PO Percentage of the principal portion of Realized Losses has previously been allocated to such Class on a pro rata basis (based on the amount of Realized Losses so allocated).

	(h)	On any Distribution Date on which any Certificate Group constitutes an Undercollateralized Group, all amounts otherwise distributable as principal on the Subordinated Certificates, in reverse order of priority (or, following the Cross- over Date, such other amounts described in the immediately following sentence), will be distributed as principal to the Senior Certificates of such Undercollateralized Group (other than the Class PO Certificates) in accordance with the priorities set forth in Section 4.2(a)(iii), until the total Class Certificate Balance of such Senior Certificates equals the Pool Principal Balance of the related Mortgage Pool (such distribution, an “Undercollateralization Distribution”). If the Senior Certificates of a Certificate Group (other than the Class PO Certificates) constitute an Undercollateralized Group on any Distribution Date following the Cross-over Date, Undercollateralization Distributions will be made from the excess of the Available Funds for the other Mortgage Pools remaining after all required amounts for that Distribution Date have been distributed to the Senior Certificates of the other Certificate Group (other than the Class PO Certificates). In addition, the amount of any unpaid Accrued Certificate Interest with respect to an Undercollateralized Group on any Distribution Date (including any Accrued Certificate Interest for the related Distribution Date) will be distributed to the Senior Certificates of the Undercollateralized Group (other than the Class PO Certificates) prior to the payment of any Undercollateralization Distributions from amounts otherwise distributable as principal on the Subordinated Certificates, in reverse order of

		priority (or, following the Cross-over Date, as provided in the preceding sentence). Except as provided otherwise in this Section 4.2(h), no distribution of principal will be made to any Class of Subordinated Certificates until each Undercollateralized Group is no longer undercollateralized.

	In addition, if on any Distribution Date the total Class Certificate Balance of the Senior Certificates of a Certificate Group (other than the Class PO Certificates) (after giving effect to distributions to be made on that Distribution Date) has been reduced to zero, all amounts otherwise distributable as prepayments of principal to the Subordinated Certificates, in reverse order of priority, will instead be distributed as principal to the Senior Certificates of the other Certificate Group (other than the Class PO Certificates) unless (a) the weighted average of the Subordinated Percentages for the Mortgage Pools, weighted on the basis of the Stated Principal Balance of the Mortgage Loans in the related Mortgage Pool (other than the Class PO Certificates), is at least two times the weighted average of the initial Subordinate Percentage for the Mortgage Pools (calculated on such basis), (b) the aggregate Stated Principal Balance of all the Mortgage Loans in the Mortgage Pools delinquent 60 days or more (including for this purpose any Mortgage Loans in foreclosure or subject to bankruptcy proceedings and Mortgage Loans with respect to which the related Mortgaged Property has been acquired by the Trust Fund), averaged over the preceding six month period, as a percentage of the then current aggregate Class Certificate Balance of the Subordinated Certificates, is less than 50%, and (c) the cumulative Realized Losses in all of the Mortgage Pools do not exceed (i) 20% of the Original Subordinated Principal Balance if such Distribution Date occurs between and including July 2007 and June 2010, and 30% of the Original Subordinated Principal Balance if such Distribution Date occurs on or after July 2010. Except as provided otherwise in this Section 4.2(h), all distributions described above will be made in accordance with the priorities set forth in Section 4.2(a) through (c) and (e).

SECTION 4.3 Method of Distribution.

	(a)	All distributions with respect to each Class of Certificates on each Distribution Date shall be made pro rata among the outstanding Certificates of such Class, based on the Percentage Interest in such Class represented by each Certificate. Payments to the Certificateholders on each Distribution Date will be made by the Trustee to the Certificateholders of record on the related Record Date by check or money order mailed to a Certificateholder at the address appearing in the Certificate Register, or upon written request by such Certificateholder to the Trustee made not later than the applicable Record Date, by wire transfer to a U.S. depository institution acceptable to the Trustee, or by such other means of payment as such Certificateholder and the Trustee shall agree.

	(b)	Each distribution with respect to a Book-Entry Certificate shall be paid to the Depository, which shall credit the amount of such distribution to the accounts of its Depository Participants in accordance with its normal procedures. Each Depository Participant shall be responsible for disbursing such distribution to the Certificate Owners that it represents and to each financial intermediary for which it acts as agent. Each such financial intermediary shall be responsible for

	disbursing funds to the Certificate Owners that it represents. All such credits and disbursements with respect to a Book-Entry Certificate are to be made by the Depository and the Depository Participants in accordance with the provisions of the applicable Certificates. Neither the Trustee nor the Master Servicer shall have any responsibility therefor except as otherwise provided by applicable law.

(c)	The Trustee shall withhold or cause to be withheld such amounts as it reasonably determines are required by the Code (giving full effect to any exemptions from withholding and related certifications required to be furnished by Certificateholders or Certificate Owners and any reductions to withholding by virtue of any bilateral tax treaties and any applicable certification required to be furnished by Certificateholders or Certificate Owners with respect thereto) from distributions to be made to Non-U.S. Persons. If the Trustee reasonably determines that a more accurate determination of the amount required to be withheld for a distribution can be made within a reasonable period after the scheduled date for such distribution, it may hold such distribution in trust for a Holder of a Residual Certificate until such determination can be made. For the purposes of this paragraph, a “Non-U.S. Person” is (i) an individual other than a citizen or resident of the United States, (ii) a partnership, corporation or entity treated as a partnership or corporation for U.S. federal income tax purposes not formed under the laws of the United States, any state thereof or the District of Columbia (unless, in the case of a partnership, Treasury regulations provide otherwise), (iii) any estate, the income of which is not subject to U.S. federal income taxation, regardless of source, and (iv) any trust, other than a trust that a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. Persons have the authority to control all substantial decisions of the trust.

	SECTION 4.4 Allocation of Losses.

(a)	On or prior to each Determination Date, the Master Servicer shall determine the amount of any Realized Loss in respect of each Mortgage Loan that occurred during the immediately preceding calendar month.

(b)	The principal portion of each Realized Loss with respect to a Mortgage Pool shall be allocated as follows:

	(i)	with respect to any Distribution Date, the applicable PO Percentage of the principal portion of any such Realized Loss on a Discount Mortgage Loan in such Mortgage Pool shall be allocated to the applicable PO Certificates until the Class Certificate Balance thereof has been reduced to zero; and

	(ii)	prior to the Cross-over Date, the applicable Non-PO Percentage of the principal portion of any such Realized Loss (except Excess Losses) (or the applicable PO Percentage thereof, in the case of the related Class PO Certificates) shall be allocated in the following order of priority:

		first, to the Class B-6 Certificates until the Class Certificate Balance thereof has been reduced to zero;

		second, to the Class B-5 Certificates until the Class Certificate Balance thereof has been reduced to zero;

		third, to the Class B-4 Certificates until the Class Certificate Balance thereof has been reduced to zero;

		fourth, to the Class B-3 Certificates until the Class Certificate Balance thereof has been reduced to zero;

		fifth, to the Class B-2 Certificates until the Class Certificate Balance thereof has been reduced to zero;

		sixth, to the Class B-1 Certificates until the Class Certificate Balance thereof has been reduced to zero; and

		seventh, to the Classes of Senior Certificates of the related Certificate Group (other than the Class PO Certificates), pro rata, in accordance with their Class Certificate Balances.

	(iii)	From and after the Cross-over Date, the applicable Non-PO Percentage of the principal portion of any Realized Loss for a Mortgage Pool will be allocated among the outstanding Classes of Senior Certificates of the related Certificate Group entitled to principal distributions (other than (i) the Class I-A-1 and Class I-A-4 Certificates, so long as the Class I-A-14 Certificates are outstanding; (ii) the Class I-A-7, Class I-A-8 and Class I- A-10 Certificates, so long as the Class I-A-11 Certificates are outstanding; and (iii) the Class PO Certificates), pro rata, based upon their Class Certificate Balances within that Certificate Group.

(c)	From and after the Cross-over Date, (i) up to $4,050,000 of the principal portion of Realized Losses (other than Excess Losses) on the Class I-A-1 Certificates, and (ii) up to $1,000,000 of the principal portion of Realized Losses (other than Excess Losses) on the Class I-A-4 Certificates will instead first be allocated pro rata (based on the respective Class Certificate Balances of the Class I-A-1 and Class I-A-4 Certificates) to the Class I-A-14 Certificates (in addition to other Realized Losses allocable to the Class I-A-14 Certificates), and not to the Class I- A-1 or Class I-A-4 Certificates, in each case until the Class Certificate Balance of the Class I-A-14 Certificates has been reduced to zero.

(d)	From and after the Cross-over Date, (i) up to $1,500,000 of the principal portion of Realized Losses (including Excess Losses) on the Class I-A-7 Certificates, (ii) up to $400,000 of the principal portion of Realized Losses (including Excess Losses) on the Class I-A-8 Certificates, and (iii) up to $4,634,000 of the principal portion of Realized Losses (including Excess Losses) on the Class I-A-10 Certificates will instead first be allocated pro rata (based on the respective Class

		Certificate Balances of the Class I-A-7, Class I-A-8 and Class I-A-10 Certificates) to the Class I-A-11 Certificates (in addition to other Realized Losses or Excess Losses allocable to the Class I-A-11 Certificates), and not to the Class I-A-7, Class I-A-8 or Class I-A-10 Certificates, in each case until the Class Certificate Balance of the Class I-A-11 Certificates has been reduced to zero.

	(e)	With respect to any Distribution Date, the applicable Non-PO Percentage of the principal portion of any Excess Loss with respect to a Mortgage Pool (other than Excess Bankruptcy Losses attributable to Debt Service Reductions) shall be allocated pro rata to each Class of Certificates (other than the Class PO Certificates) of the related Certificate Group based on their respective Class Certificate Balances (in the case of the Senior Certificates) or Apportioned Principal Balances (in the case of the Subordinated Certificates).

	(f)	Any Realized Losses allocated to a Class of Certificates pursuant to Section 4.4(b) shall be allocated among the Certificates of such Class in proportion to their respective Certificate Principal Balances. Any allocation of Realized Losses pursuant to this paragraph (f) shall be accomplished by reducing the Certificate Principal Balances of the related Certificates on the related Distribution Date in accordance with Section 4.4(g).

	(g)	Realized Losses allocated in accordance with this Section 4.4 shall be allocated on the Distribution Date in the month following the month in which such loss was incurred and in the case of the principal portion thereof, after giving effect to the distributions made on such Distribution Date. The aggregate amount of Realized Losses to be allocated to the Class PO Certificates on such Distribution Date will be taken into account in determining distributions in respect of any Class PO Deferred Amount for such Distribution Date.

	(h)	On each Distribution Date, the Master Servicer shall determine the Subordinated Certificate Writedown Amount, if any. Any such Subordinated Certificate Writedown Amount shall effect, without duplication of any other provision in this Section 4.4 that provides for a reduction in the Class Certificate Balance of the Subordinated Certificates, a corresponding reduction in the Class Certificate Balance of the Subordinated Certificates, which reduction shall occur on such Distribution Date after giving effect to distributions made on such Distribution Date.

	(i)	Notwithstanding the foregoing, no such allocation of any Realized Loss shall be made on a Distribution Date to a Class of Certificates to the extent that such allocation would result in the reduction of the aggregate Class Certificate Balances of all the Senior Certificates of a related Certificate Group as of such Distribution Date plus the Apportioned Principal Balances of the Subordinated Certificates of such Certificate Group as of such Distribution Date, after giving effect to all distributions and prior allocations of Realized Losses on such date, to an amount less than the aggregate Stated Principal Balance of the Mortgage Loans in the related Mortgage Pool as of the first day of the month of such Distribution

	Date, less any Deficient Valuations occurring on or prior to the Bankruptcy Coverage Termination Date (such limitation, the “Loss Allocation Limitation”).

	year or applicable portion thereof during which such Person was a Certificateholder. Such obligation of the Trustee shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Trustee pursuant to any requirements of the Code as from time to time in effect.

	SECTION 4.7 Reserve Fund.

(a)	On the Closing Date, the Trustee shall (i) establish and maintain in its name, in trust for the benefit of the holders of the Class I-A-1 Certificates, the Reserve Fund, and (ii) the Depositor will deposit or cause to be deposited $1,000 in the Reserve Fund. The Reserve Fund shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other moneys, including without limitation other moneys of the Trustee held pursuant to this Agreement. The Corridor Residual Owner will own the residual interest in the Reserve Fund. The Reserve Fund shall be an asset of the Separate Interest Trust.

(b)	On each Distribution Date prior to the Corridor Contract Termination Date, the Trustee will deposit any amounts received under the Corridor Contract into the Reserve Fund. Amounts on deposit, if any, in the Reserve Fund shall be distributed in the following order of priority:

	(i)	on any Distribution Date for which a Basis Risk Shortfall exists in respect of the Class I-A-1 Certificates, the Trustee shall withdraw from the Reserve Fund an amount equal to the lesser of (i) the Class I-A-1 Yield Supplement Amount for such Distribution Date and (ii) the remaining balance in the Reserve Fund on such Distribution Date, and distribute such amount to the Holders of the Class I-A-1 Certificates;

	(ii)	on any Distribution Date for which an Unpaid Basis Risk Shortfall exists on the Class I-A-1 Certificates, the Trustee shall withdraw from the Reserve Fund an amount equal to the lesser of (i) the amount of such Unpaid Basis Risk Shortfall for such Distribution Date and (ii) the remaining balance in the Reserve Fund on such Distribution Date, and distribute such amount to the Holders of the Class I-A-1 Certificates; and

	(iii)	on any Distribution Date for which a Carryover Unpaid Basis Risk Shortfall exists on the Class I-A-1 Certificates, the Trustee shall withdraw from the Reserve Fund an amount equal to the lesser of (i) the amount of such Carryover Unpaid Basis Risk Shortfall with interest thereon at the applicable Pass-Through Rate (calculated without regard to the maximum Pass-Through Rate limitation) for such Distribution Date and (ii) the remaining balance in the Reserve Fund on such Distribution Date, and distribute such amount to the Corridor Residual Owner.

	(c)	Any amounts remaining on deposit in the Reserve Fund after the Trustee has made the foregoing distributions shall remain in the Reserve Fund to be used as necessary to pay the amounts described in clauses (i) through (iii) of Section 4.7(b) above. On the Distribution Date immediately following the date on which the Class Certificate Balance of the Class I-A-1 Certificates is reduced to zero, the Trustee shall distribute any amounts remaining in the Reserve Fund to the Corridor Residual Owner and terminate the Reserve Fund.

	(d)	If the Corridor Contract is terminated early and the Corridor Contract Counterparty owes a termination payment thereunder, the Trustee shall allocate the amount of any such termination payment between the Reserve Fund and the Corridor Residual Owner, as follows, (A) with respect to the Reserve Fund, an amount equal to the product of (i) a fraction, the numerator of which is the lesser of (x) the Corridor Contract Notional Amount for the first Distribution Date on or after the early termination and (y) the Class Certificate Balance of the Class I-A-1 Certificates immediately prior to the first Distribution Date on or after the early termination, and the denominator of which is the Corridor Contract Notional Amount for the first Distribution Date on or after the early termination and (ii) the termination payment amount, and (B) with respect to the Corridor Reserve Owner, an amount equal to any excess of the termination payment amount over the amounts payable pursuant to clause (A) above, if any. The Trustee shall apply the portion of any termination payment that is allocated to the Reserve Fund on future Distribution Dates to pay any Class I-A-1 Yield Supplement Amounts on the Class I-A-1 Certificates, until the Corridor Contract Termination Date.

	(e)	Funds in the Reserve Fund shall be invested in Permitted Investments. Any earnings on amounts in the Reserve Fund shall be for the benefit of the Corridor Residual Owner. The Corridor Residual Owner shall own the Reserve Fund for federal income tax purposes and the Corridor Residual Owner shall direct the Trustee, in writing, as to investment of amounts on deposit therein. The Corridor Residual Owner shall be liable for any losses incurred on such investments. In the absence of written instructions from the Corridor Residual Owner as to investment of funds on deposit in the Reserve Fund, such funds shall be held uninvested.

		SECTION 4.8 Separate Interest Trust.

	(a)	The Depositor hereby creates a trust, separate from the Trust, for the benefit of the holders of the Class I-A-1 (such trust is referred to herein as the “Separate Interest Trust”) and hereby transfers, assigns and conveys the sum of $1.00 into the Separate Interest Trust. The Corridor Contract and the Reserve Fund will also be assets of the Separate Interest Trust. The Trustee shall be the trustee of the Separate Interest Trust and shall have no responsibility for the contents, adequacy or sufficiency of the Corridor Contract, including, without limitation, the representations and warranties of the parties contained therein. The Corridor Residual Owner will own the residual interest in the Separate Interest Trust. The

		Separate Interest Trust shall not be an asset of the Trust Fund or any REMIC established hereby.

	(b)	In addition to the deposits to be made on each Distribution Date pursuant to Section 4.7(b), the Trustee shall deposit into the Reserve Fund any and all amounts received from time to time from the Corridor Contract Counterparty in respect of the Corridor Contract.

	(c)	The Trustee will treat the Separate Interest Trust for Federal tax purposes as a grantor trust with the Corridor Residual Owner as the sole beneficiary and will apply for a separate Federal tax identification number for the Separate Interest Trust.

	(d)	Upon the termination of the Reserve Fund, as provided in Section 4.7(c), the Trustee shall terminate the Separate Interest Trust. Upon termination of the Reserve Fund and the Separate Interest Trust, any amounts remaining in the Reserve Fund and Separate Interest Trust after payment of the amounts, if any, owed to the holders of the Class I-A-1 Certificates, shall be distributed to the Corridor Residual Owner.

		SECTION 4.9 Determination of Pass-Through Rates for LIBOR Certificates.

	(a)	On each LIBOR Determination Date so long as any LIBOR Certificates are outstanding, the Trustee will determine LIBOR on the basis of the British Bankers’ Association (“BBA”) “Interest Settlement Rate” for one-month deposits in U.S. dollars as quoted on the Bloomberg Terminal as of each LIBOR Determination Date. If on any LIBOR Determination Date, LIBOR cannot be determined as provided in the preceding sentence, the Trustee shall either (i) request each Reference Bank to inform the Trustee of the quotation offered by its principal London office for making one-month United States dollar deposits in leading banks in the London interbank market, as of 11:00 a.m. (London time) on such LIBOR Determination Date or (ii) in lieu of making any such request, rely on such Reference Bank quotations that appear at such time on the Reuters Screen LIBOR Page (as defined in the International Swap Dealers Association Inc. Code of Standard Wording, Assumptions and Provisions for Swaps, 1986 Edition), to the extent available. LIBOR for the initial LIBOR Determination Date will be equal to the Initial LIBOR Rate.

	(b)	If LIBOR cannot be determined as provided in paragraph (a) of this Section 4.9, the Trustee shall either (i) request each Reference Bank inform the Trustee of the quotation offered by such Reference Bank’s principal London office for making one-month United States dollar deposits in leading banks in the London interbank market, as of 11:00 a.m. (London time) on such LIBOR Determination Date or (ii) in lieu of making any such request, rely on such Reference Bank quotations that appear at such time on the Reuters Screen LIBOR Page (as defined in the International Swap Dealers Association Inc. Code of Standard Wording, Assumptions and Provisions for Swaps, 1986 Edition) to the extent available.

		With respect to clause (i) above, LIBOR for the next Interest Accrual Period will be established by the Trustee on each LIBOR Determination Date as follows:

		(i)	If on any LIBOR Determination Date two or more Reference Banks provide such offered quotations, LIBOR for the next Interest Accrual Period shall be the arithmetic mean of such offered quotations (rounding such arithmetic mean upwards if necessary to the nearest whole multiple of 1/32%).

		(ii)	If on any LIBOR Determination Date only one or none of the Reference Banks provides such offered quotations, LIBOR for the next Interest Accrual Period shall be whichever is the higher of (i) LIBOR as determined on the previous LIBOR Determination Date or (ii) the Reserve Interest Rate. The “Reserve Interest Rate” shall be the rate per annum which the Trustee determines to be either (i) the arithmetic mean (rounded upwards if necessary to the nearest whole multiple of 1/32%) of the one- month United States dollar lending rates that New York City banks selected by the Trustee are quoting, on the relevant LIBOR Determination Date, to the principal London offices of at least two of the Reference Banks to which such quotations are, in the opinion of the Trustee, being so made, or (ii) in the event that the Trustee can determine no such arithmetic mean, the lowest one-month United States dollar lending rate which New York City banks selected by the Trustee are quoting on such LIBOR Determination Date to leading European banks.

		(iii)	If on any LIBOR Determination Date the trustee is required but is unable to determine the Reserve Interest Rate in the manner provided in paragraph (b) above, LIBOR shall be LIBOR as determined on the preceding LIBOR Determination Date.

The Master Servicer shall designate at least four Reference Banks. Until all of the LIBOR Certificates are paid in full, the Trustee will refer to the four Reference Banks designated by the Master Servicer to determine LIBOR with respect to each LIBOR Determination Date. Each “Reference Bank” shall be a leading bank engaged in transactions in Eurodollar deposits in the international Eurocurrency market, shall not control, be controlled by, or be under common control with, the Trustee and shall have an established place of business in London. If any such Reference Bank should be unwilling or unable to act as such, the Master Servicer shall promptly appoint or cause to be appointed another Reference Bank. The Trustee shall have no liability or responsibility to any Person for (i) the selection of any Reference Bank for purposes of determining LIBOR or (ii) any inability of the Master Servicer to designate at least four Reference Banks.

	(c)	The Pass-Through Rate for each Class of LIBOR Certificates for each Interest Accrual Period shall be determined by the Trustee on each LIBOR Determination Date so long as the LIBOR Certificates are outstanding on the basis of LIBOR and the respective formulae appearing in footnotes corresponding to the LIBOR Certificates in the table relating to the Certificates in the Preliminary Statement.

In determining LIBOR, any Pass-Through Rate for the LIBOR Certificates, any Interest Settlement Rate, or any Reserve Interest Rate, the Trustee may conclusively rely and shall be protected in relying upon the offered quotations (whether written, oral or on the Bridge Telerate Service) from the BBA designated banks, the Reference Banks or the New York City banks as to LIBOR, the Interest Settlement Rate or the Reserve Interest Rate, as appropriate, in effect from time to time. The Trustee shall not have any liability or responsibility to any Person for (i) the Trustee’s selection of New York City banks for purposes of determining any Reserve Interest Rate or (ii) its inability, following a good-faith reasonable effort, to obtain such quotations from, the BBA designated banks, the Reference Banks or the New York City banks or to determine such arithmetic mean, all as provided for in this Section 4.9.

	(d)	The establishment of LIBOR and each Pass-Through Rate for the LIBOR Certificates by the Trustee shall (in the absence of manifest error) be final, conclusive and binding upon each Holder of a Certificate and the Trustee.

		SECTION 4.10 The Yield Supplement Account.

	(a)	On the Closing Date, the Trustee shall (i) establish and maintain in its name, in trust for the benefit of the holders of the Class I-A-6 Certificates, the Yield Supplement Account, and (ii) the Corridor Residual Owner will deposit or cause to be deposited $1,050,000 into the Yield Supplement Account. The Yield Supplement Account shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other moneys, including without limitation other moneys of the Trustee held pursuant to this Agreement. The Corridor Residual Owner will own the residual interest in the Yield Supplement Account. The Yield Supplement Account shall not be an asset of any REMIC.

	(b)	On any Distribution Date occurring on or prior to the June 2008 Distribution Date for which a Basis Risk Shortfall exists in respect of the Class I-A-6 Certificates, the Trustee shall withdraw from the Yield Supplement Account an amount equal to the lesser of (i) the Class I-A-6 Yield Supplement Amount for such Distribution Date and (ii) the remaining balance in the Yield Supplement Account on such Distribution Date, and distribute such amount to the Holders of the Class I-A-6 Certificates.

	(c)	On the Business Day immediately following the June 2008 Distribution Date, the Trustee shall distribute any amounts remaining in the Yield Supplement Account to the Corridor Residual Owner and shall terminate the Yield Supplement Account.

	(d)	Funds in the Yield Supplement Account shall be invested in Permitted Investments. Any earnings on amounts in the Yield Supplement Account shall be for the benefit of the Corridor Residual Owner. The Corridor Residual Owner shall own the Yield Supplement Account for federal income tax purposes and the Corridor Residual Owner shall direct the Trustee, in writing, as to investment of amounts on deposit therein. The Corridor Residual Owner shall be liable for any

losses incurred on such investments. In the absence of written instructions from the Corridor Residual Owner as to investment of funds on deposit in the Yield Supplement Account, such funds shall be held uninvested.

ARTICLE V
THE CERTIFICATES

SECTION 5.1 The Certificates.

The Certificates shall be substantially in the forms attached hereto as exhibits. The Certificates shall be issuable in registered form, in the minimum denominations, integral multiples in excess thereof (except that one Certificate in each Class may be issued in a different amount which must be in excess of the applicable minimum denomination) and aggregate denominations per Class set forth in the Preliminary Statement.

Subject to Section 9.2 hereof respecting the final distribution on the Certificates, on each Distribution Date the Trustee shall make distributions to each Certificateholder of record on the preceding Record Date either (x) by wire transfer in immediately available funds to the account of such Holder at a bank or other entity having appropriate facilities therefor, if (i) such Holder has so notified the Trustee at least five Business Days prior to the related Record Date and (ii) such Holder shall hold (A) 100% of the Class Certificate Balance of any Class of Certificates or (B) Certificates of any Class with aggregate principal Denominations of not less than $1,000,000 or (y) by check mailed by first class mail to such Certificateholder at the address of such Holder appearing in the Certificate Register.

The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by an authorized officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Trustee shall bind the Trustee, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the countersignature and delivery of such Certificates or did not hold such offices at the date of such Certificate. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless countersigned by the Trustee by manual signature, and such countersignature upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly executed and delivered hereunder. All Certificates shall be dated the date of their countersignature. On the Closing Date, the Trustee shall countersign the Certificates to be issued at the direction of the Depositor, or any affiliate thereof.

The Depositor shall provide, or cause to be provided, to the Trustee on a continuous basis, an adequate inventory of Certificates to facilitate transfers.

SECTION 5.2 Certificate Register; Registration of Transfer and Exchange of Certificates.

	(a)	The Trustee shall maintain, or cause to be maintained in accordance with the provisions of Section 5.6 hereof, a Certificate Register for the Trust Fund in which, subject to the provisions of subsections (b) and (c) below and to such reasonable regulations as it may prescribe, the Trustee shall provide for the

registration of Certificates and of transfers and exchanges of Certificates as herein provided. Upon surrender for registration of transfer of any Certificate, the Trustee shall execute and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same Class and aggregate Percentage Interest.

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest upon surrender of the Certificates to be exchanged at the office or agency of the Trustee. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, authenticate, and deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge to the Certificateholders shall be made for any registration of transfer or exchange of Certificates, but payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates may be required.

All Certificates surrendered for registration of transfer or exchange shall be cancelled and subsequently destroyed by the Trustee in accordance with the Trustee’s customary procedures.


	(b)	No transfer of a Private Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such state securities laws. In the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, any Holder of a Private Certificate (other than a Private Certificate that is a Book-Entry Certificate) desiring to effect such transfer and such Certificateholder’s prospective transferee shall each certify to the Trustee in writing the facts surrounding the transfer in substantially the forms set forth in Exhibit I (the “Transferor Certificate”) and (i) deliver a letter in substantially the form of either Exhibit J (the “Investment Letter”) or Exhibit K (the “Rule 144A Letter”) or (ii) there shall be delivered to the Trustee at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the Securities Act.

Each Holder of a Private Certificate that is a Book-Entry Certificate, by its acquisition thereof (or a beneficial interest therein), shall be deemed to have represented and warranted for the benefit of the Depositor, the Servicer and the Trustee that (a) it understands that the Private Certificates are not being registered under the Securities Act, or any state securities laws and are being transferred to it in a transaction that is exempt from the registration requirements of the Securities Act and any such laws, (b) it has such

knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of investments in the Private Certificates, (c) it has had the opportunity to ask questions of and receive answers from the Depositor concerning the purchase of the Private Certificates and all matters relating thereto or any additional information deemed necessary to its decision to purchase the Private Certificates, (d) neither it, nor any anyone acting on its behalf, has offered, transferred, pledged, sold or otherwise disposed of the Private Certificates or any interest therein, or solicited any offer to buy or accept a transfer, pledge or other disposition of the Private Certificates or any interest therein from, or otherwise approached or negotiated with respect to the Private Certificates or any interest therein with, any person in any manner, or made any general solicitation by means of general advertising or in any other manner, or taken any other action, that would constitute a distribution of the Private Certificates under the Securities Act or that would render the disposition of the Private Certificates a violation of Section 5 of the Securities Act or require registration pursuant thereto, nor will it act, nor has it authorized or will authorize any person to act, in such manner with respect to the Private Certificates, (e) it is a “qualified institutional buyer” as that term is defined in Rule 144A under the Securities Act (“Rule 144A”), (f) it is aware that the sale of the Private Certificates to it is being made in reliance on Rule 144A, (g) it is acquiring the Private Certificates for its own account or for resale pursuant to Rule 144A and it understands that the Private Certificates may be resold, pledged or transferred only (A) to a person whom it reasonably believes to be a qualified institutional buyer that purchases for its own account or for the account of a qualified institutional buyer to whom notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A, or (B) pursuant to another exemption from registration under the Securities Act; and (h) it understands that no representation is made as to the availability of the exemption provided by Rule 144A for resales of the Private Certificates.

The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Certificate without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A. The Trustee and the Master Servicer shall cooperate with the Depositor in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Depositor shall reasonably request to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such transfer shall, and by its acceptance of a Private Certificate does hereby agree to, indemnify the Trustee and the Depositor, the Seller and the Master Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of an ERISA-Restricted Certificate (in the form of a Definitive Certificate) shall be made unless the Trustee shall have received a Transferor Certificate from the related transferor and either (i) a representation from the transferee of such Certificate acceptable to and in form and substance satisfactory to the Trustee (in the event such Certificate is a Private Certificate, such requirement is satisfied only by the

Trustee’s receipt of a representation letter from the transferee substantially in the form of Exhibit J or Exhibit K), to the effect that such transferee is not an employee benefit plan or arrangement subject to Section 406 of ERISA or a plan or arrangement subject to Section 4975 of the Code, nor a person acting on behalf of any such plan or arrangement, nor using the assets of any such plan or arrangement to effect such transfer, (ii) in the case of a Private Certificate (that has been subject to an ERISA-Qualified Underwriting) or a Residual Certificate, if the purchaser is an insurance company, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any such ERISA-Restricted Certificate presented for registration in the name of an employee benefit plan subject to ERISA, or a plan or arrangement subject to Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a trustee of any such plan or any other person acting on behalf of any such plan or arrangement, or using such plan’s or arrangement’s assets, an Opinion of Counsel satisfactory to the Trustee, which Opinion of Counsel shall not be an expense of either the Trustee, the Depositor, the Master Servicer or the Trust Fund, addressed to the Trustee to the effect that the purchase or holding of such ERISA-Restricted Certificate will not result in prohibited transactions under Title I of ERISA and Section 4975 of the Code and will not subject the Trustee, the Depositor or the Master Servicer to any obligation in addition to those expressly undertaken in this Agreement or to any liability. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Certificate to or on behalf of an employee benefit plan subject to ERISA or to the Code without the delivery to the Trustee of an Opinion of Counsel satisfactory to the Trustee as described above shall be void and of no effect.

Each Holder of a Private Certificate that is a Book-Entry Certificate, by its acquisition thereof (or a beneficial interest therein) shall be deemed to have represented and warranted for the benefit of the Depositor, the Servicer, the Trustee and the other Certificateholders, that (a) it is not an employee benefit plan or arrangement that is subject to Section 406 of ERISA, or a plan or arrangement that is subject to Section 4975 of the Internal Revenue Code of 1986, as amended, nor is it acting on behalf of any such plan or arrangement or using the assets of any such plan or arrangement to effect such acquisition, or (b) if it is an insurance company, in the case of Private Certificates that have been the subject of an ERISA-Qualifying Underwriting, it is purchasing the Private Certificates with funds contained in an “insurance company general account” (as defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and its purchase and holding of the Private Certificates are covered under Sections I and III of PTCE 95-60.

To the extent permitted under applicable law (including, but not limited to, ERISA), the Trustee shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 5.2(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trustee in accordance with the foregoing

requirements. The Trustee shall be entitled, but not obligated, to recover from any Holder of any ERISA-Restricted Certificate that was in fact a Plan or a Person acting on behalf of any such Plan any payments made on such ERISA-Restricted Certificate at and after either such time. Any such payments so recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Holder of such Certificate that is not such a Plan or Person acting on behalf of a Plan.

No transfer of an ERISA-Restricted Yield Supplement Certificate in the form of a Definitive Certificate shall be made unless the Trustee shall have received a representation letter from the transferee of such Certificate to the effect that either (i) such transferee is neither a Plan nor a Person acting on behalf of any such Plan or using the assets of any such Plan to effect such transfer or (ii) the acquisition and holding of the ERISA-Restricted Yield Supplement Certificate are eligible for exemptive relief under Prohibited Transaction Class Exemption (“PTCE”) 84-14, XXXX 00-0, XXXX 00-00, XXXX 95-60 or PTCE 96-23. Any purported transfer of an ERISA-Restricted Yield Supplement Certificate in the form of a Definitive Certificate on behalf of a Plan without the delivery to the Trustee of a representation letter as described above shall be void and of no effect. If the ERISA-Restricted Yield Supplement Certificate is a Book-Entry Certificate, the transferee will be deemed to have made a representation as provided in clause (i) or (ii) of this paragraph, as applicable.

If any ERISA-Restricted Yield Supplement Certificate, or any interest therein, is acquired or held in violation of the provisions of the preceding paragraph, the next preceding permitted beneficial owner will be treated as the beneficial owner of that Certificate, retroactive to the date of transfer to the purported beneficial owner. Any purported beneficial owner whose acquisition or holding of an ERISA-Restricted Yield Supplement Certificate, or interest therein, was effected in violation of the provisions of the preceding paragraph shall indemnify to the extent permitted by law and hold harmless the Depositor, Custodian, the Trustee, and the Master Servicer from and against any and all liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition or holding.

To the extent permitted under applicable law (including, but not limited to, ERISA), the Trustee shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Yield Supplement Certificate that is in fact not permitted by this Section 5.2(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trustee in accordance with the foregoing requirements.

Notwithstanding the foregoing, no opinion or certificate shall be required for the initial issuance of any ERISA-Restricted Certificate or ERISA-Restricted Yield Supplement Certificate that is registered in the name of the Depository or its nominee.

	(c)	Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions, and the rights of

		each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

		(i)	Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Trustee of any change or impending change in its status as a Permitted Transferee.

		(ii)	No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Trustee shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Trustee under subparagraph (b) above, the Trustee shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee in the form attached hereto as Exhibit H and with a certificate of the proposed transferor in the form attached hereto as Exhibit I.

		(iii)	Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee.

		(iv)	Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 5.2(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.2(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 5.2(b) and this Section 5.2(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and, in the case of a Residual Certificate which is also a Private Certificate, either the Rule 144A Letter or the Investment Letter. The Trustee shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments

		so recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Permitted Transferee of such Certificate.

	(v)	The Depositor shall use its best efforts to make available, upon receipt of written request from the Trustee, all information necessary to compute any tax imposed under Section 860E(e) of the Code as a result of a Transfer of an Ownership Interest in a Residual Certificate to any Holder who is not a Permitted Transferee.

The restrictions on Transfers of a Residual Certificate set forth in this Section 5.2(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Seller or the Master Servicer, to the effect that the elimination of such restrictions will not cause any REMIC created hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is not a Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate which is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.

(d)	The preparation and delivery of all certificates and opinions referred to above in this Section 5.2 in connection with transfer shall be at the expense of the parties to such transfers.

(e)	Except as provided below, the Book-Entry Certificates shall at all times remain registered in the name of the Depository or its nominee and at all times: (i) registration of the Certificates may not be transferred by the Trustee except to another Depository; (ii) the Depository shall maintain book-entry records with respect to the Certificate Owners and with respect to ownership and transfers of such Book-Entry Certificates; (iii) ownership and transfers of registration of the Book-Entry Certificates on the books of the Depository shall be governed by applicable rules established by the Depository; (iv) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants; (v) the Trustee shall deal with the Depository, Depository Participants and indirect participating firms as representatives of the Certificate Owners of the Book-Entry Certificates for purposes of exercising the rights of holders under this Agreement, and requests and directions for and votes of such representatives shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; and (vi) the Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the Depository Participants with respect

to indirect participating firms and persons shown on the books of such indirect participating firms as direct or indirect Certificate Owners.

All transfers by Certificate Owners of Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owner. Each Depository Participant shall only transfer Book-Entry Certificates of Certificate Owners it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures.

If (x) (i) the Depository or the Depositor advises the Trustee in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository, and (ii) the Trustee or the Depositor is unable to locate a qualified successor, (y) the Depositor at its option advises the Trustee in writing that it elects to terminate the book-entry system through the Depository or (z) after the occurrence of an Event of Default, Certificate Owners representing at least 51% of the Class Certificate Balance of the Book-Entry Certificates together advise the Trustee and the Depository through the Depository Participants in writing that the continuation of a book-entry system through the Depository is no longer in the best interests of the Certificate Owners, the Trustee shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of definitive, fully-registered Certificates (the “Definitive Certificates”) to Certificate Owners requesting the same. Upon surrender to the Trustee of the related Class of Certificates by the Depository, accompanied by the instructions from the Depository for registration, the Trustee shall issue the Definitive Certificates. Neither the Master Servicer, the Depositor nor the Trustee shall be liable for any delay in delivery of such instruction and each may conclusively rely on, and shall be protected in relying on, such instructions. The Master Servicer shall provide the Trustee with an adequate inventory of certificates to facilitate the issuance and transfer of Definitive Certificates. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Trustee, to the extent applicable with respect to such Definitive Certificates and the Trustee shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder; provided that the Trustee shall not by virtue of its assumption of such obligations become liable to any party for any act or failure to act of the Depository.

SECTION 5.3 Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Trustee, or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to the Master Servicer and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute, countersign and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like Class, tenor and Percentage Interest. In connection with the issuance of any new Certificate under this Section 5.3, the Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Any replacement Certificate issued pursuant to this Section 5.3 shall constitute complete and indefeasible evidence of ownership, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

SECTION 5.4 Persons Deemed Owners.

The Master Servicer, the Trustee and any agent of the Master Servicer or the Trustee may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and neither the Master Servicer, the Trustee nor any agent of the Master Servicer or the Trustee shall be affected by any notice to the contrary.

SECTION 5.5 Access to List of Certificateholders’ Names and Addresses.

If three or more Certificateholders or Certificate Owners (a) request such information in writing from the Trustee, (b) state that such Certificateholders or Certificate Owners desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates, and (c) provide a copy of the communication which such Certificateholders or Certificate Owners propose to transmit, or if the Depositor or Master Servicer shall request such information in writing from the Trustee, then the Trustee shall, within ten Business Days after the receipt of such request, provide the Depositor, the Master Servicer or such Certificateholders or Certificate Owners at such recipients’ expense the most recent list of the Certificateholders of such Trust Fund held by the Trustee, if any. The Depositor and every Certificateholder or Certificate Owner, by receiving and holding a Certificate, agree that the Trustee shall not be held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

SECTION 5.6 Maintenance of Office or Agency.

The Trustee will maintain or cause to be maintained at its expense an office or offices or agency or agencies in New York City where Certificates may be surrendered for registration of transfer or exchange. The Trustee initially designates its Corporate Trust Office for such purposes. The Trustee will give prompt written notice to the Certificateholders of any change in such location of any such office or agency.

ARTICLE VI

THE DEPOSITOR AND THE MASTER SERVICER

SECTION 6.1 Respective Liabilities of the Depositor and the Master Servicer.

The Depositor and the Master Servicer shall each be liable in accordance herewith only to the extent of the obligations specifically and respectively imposed upon and undertaken by them herein.

SECTION 6.2 Merger or Consolidation of the Depositor or the Master Servicer.

100

The Depositor and the Master Servicer will each keep in full effect its existence, rights and franchises as a corporation under the laws of the United States or under the laws of one of the states thereof and will each obtain and preserve its qualification to do business as a foreign corporation in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement, or any of the Mortgage Loans and to perform its respective duties under this Agreement.

Any Person into which the Depositor or the Master Servicer may be merged or consolidated, or any Person resulting from any merger or consolidation to which the Depositor or the Master Servicer shall be a party, or any person succeeding to the business of the Depositor or the Master Servicer, shall be the successor of the Depositor or the Master Servicer, as the case may be, hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or surviving Person to the Master Servicer shall be qualified to sell mortgage loans to, and to service mortgage loans on behalf of, FNMA or FHLMC.

SECTION 6.3 Limitation on Liability of the Depositor, the Master Servicer and Others.

None of the Depositor, the Master Servicer or any of the directors, officers, employees or agents of the Depositor or the Master Servicer shall be under any liability to the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Master Servicer or any such Person against any breach of representations or warranties made by it herein or protect the Depositor, the Master Servicer or any such Person from any liability which would otherwise be imposed by reasons of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder. The Depositor, the Master Servicer and any director, officer, employee or agent of the Depositor or the Master Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Depositor, the Master Servicer and any director, officer, employee or agent of the Depositor or the Master Servicer shall be indemnified by the Trust Fund and held harmless against any loss, liability or expense incurred in connection with any audit, controversy or judicial proceeding relating to a governmental taxing authority or any legal action relating to this Agreement or the Certificates, other than any loss, liability or expense related to any specific Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement) and any loss, liability or expense incurred by reason of willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder. Neither the Depositor nor the Master Servicer shall be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its respective duties hereunder and which in its opinion may involve it in any expense or liability; provided, however, that either the Depositor or the Master Servicer may in its discretion undertake any such action that it may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto and interests of the Trustee and the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs

101

and liabilities of the Trust Fund, and the Depositor and the Master Servicer shall be entitled to be reimbursed therefor out of the applicable subaccount of the Certificate Account.

SECTION 6.4 Limitation on Resignation of Master Servicer.

The Master Servicer shall not resign from the obligations and duties hereby imposed on it except (a) upon appointment of a successor servicer and receipt by the Trustee of a letter from each Rating Agency that such a resignation and appointment will not result in a downgrading of the rating of any of the Certificates, or (b) upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination under clause (b) permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee. No such resignation shall become effective until the Trustee or a successor master servicer shall have assumed the Master Servicer’s responsibilities, duties, liabilities and obligations hereunder.

ARTICLE VII
DEFAULT

SECTION 7.1 Events of Default.

(a)	“Event of Default,” wherever used herein, means any one of the following events:

	(i)	any failure by the Master Servicer to deposit in the applicable subaccount of the Certificate Account or remit to the Trustee any payment required to be made under the terms of this Agreement, which failure shall continue unremedied for five days after the date upon which written notice of such failure shall have been given to the Master Servicer by the Trustee or the Depositor or to the Master Servicer and the Trustee by the Holders of Certificates having not less than 25% of the Voting Rights evidenced by the Certificates; or

	(ii)	any failure by the Master Servicer to observe or perform in any material respect any other of the covenants or agreements on the part of the Master Servicer contained in this Agreement (except with respect to failure related to a Limited Exchange Act Reporting Obligation), which failure materially affects the rights of Certificateholders, which failure continues unremedied for a period of 60 days after the date on which written notice of such failure shall have been given to the Master Servicer by the Trustee or the Depositor, or to the Master Servicer and the Trustee by the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates; provided, however, that the 60-day cure period shall not apply to the initial delivery of the Mortgage File for Delay Delivery Mortgage Loans nor the failure to substitute or repurchase in lieu thereof; or

	(iii)	a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and

102

			liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 consecutive days; or

		(iv)	the Master Servicer shall consent to the appointment of a receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to the Master Servicer or all or substantially all of the property of the Master Servicer; or

		(v)	the Master Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of, or commence a voluntary case under, any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

		(vi)	the failure of the Master Servicer to remit any Advance required to be remitted by the Master Servicer pursuant to Section 4.1 which failure continues unremedied at 11:00 a.m., Central time, on the related Distribution Date.

If an Event of Default described in clauses (i) to (v) of this Section shall occur, then, and in each and every such case, so long as such Event of Default shall not have been remedied, the Trustee may, or at the direction of the Holders of Certificates evidencing not less than 66 2/3% of the Voting Rights evidenced by the Certificates, the Trustee shall by notice in writing to the Master Servicer (with a copy to each Rating Agency), terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder. If an Event of Default described in clause (vi) of this Section shall occur, the Trustee shall immediately, by notice in writing to the Master Servicer (with a copy to each Rating Agency), terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and proceeds thereof, other than its rights as a Certificateholder hereunder. In addition, if during the period that the Depositor is required to file Exchange Act Reports with respect to the Trust Fund, the Master Servicer shall fail to observe or perform any of the obligations set forth in Section 3.16(a) or Section 10.1(a)(i) and (ii), and such failure continues for the lesser of ten (10) calendar days or such period in which the applicable Exchange Act Report can be filed timely (without taking into account any extensions), so long as such failure shall not have been remedied, the Trustee shall, but only at the direction of the Depositor, terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder. The Depositor shall not be entitled to terminate the rights and obligations of the Master Servicer if a failure of the Master Servicer to identify a Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB was attributable solely to the role or functions of such Subcontractor with respect to mortgage loans other than the Mortgage Loans. On and after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer hereunder, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee or another successor to the Master Servicer appointed by the Trustee pursuant to Section

103

7.2. The Trustee, in its capacity as successor to the Master Servicer, shall thereupon make any Advance which the Master Servicer failed to make subject to Section 4.1 hereof. The Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise. Unless expressly provided in such written notice, no such termination shall affect any obligation of the Master Servicer to pay amounts owed pursuant to Article VIII. The Master Servicer agrees to cooperate with the Trustee in effecting the termination of the Master Servicer’s responsibilities and rights hereunder, including, without limitation, the transfer to the Trustee of all cash amounts which shall at the time be credited to the Certificate Account, or thereafter be received with respect to the Mortgage Loans. All expenses incurred in the transferring of the servicing duties from the Master Servicer to a Successor Servicer shall be paid by the Master Servicer, and if not paid by the Master Servicer, shall be paid from amounts on deposit in the Certificate Account.

Notwithstanding any termination of the activities of the Master Servicer hereunder, the Master Servicer shall be entitled to receive, out of any late collection of a Scheduled Payment on a Mortgage Loan which was due prior to the notice terminating such Master Servicer’s rights and obligations as Master Servicer hereunder and received after such notice, that portion thereof to which such Master Servicer would have been entitled pursuant to Sections 3.8(a)(i) through (viii),and any other amounts payable to such Master Servicer hereunder the entitlement to which arose prior to the termination of its activities hereunder. Any termination of the activities of the Master Servicer hereunder will simultaneously result in the termination of the Master Servicer’s duties as a subservicer pursuant to the Servicing Rights Transfer and Subservicing Agreement.

If the Master Servicer is terminated, the Trustee shall provide the Depositor in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to a successor master servicer in the event the Trustee should succeed to the duties of the Master Servicer as set forth herein.

In the event the Master Servicer is terminated pursuant to this Section 7.1, the Retained Yield shall remain payable to (a) First Horizon, in its individual capacity as Seller, or (b) a subsequent owner of such Retained Yield through Seller’s sale, assignment, or certification of its rights to such Retained Yield, and shall not be payable to the Trustee or any successor to the Master Servicer. Seller’s exclusive right to receive payments of Retained Yield or sell, assign, certificate or otherwise dispose of such right to receive such Retained Yield is enforceable against the Master Servicer or its successor thereto.

SECTION 7.2 Trustee to Act; Appointment of Successor.

On and after the time the Master Servicer receives a notice of termination pursuant to Section 7.1 hereof, the Trustee shall, subject to and to the extent provided in Section 3.4, be the successor to the Master Servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof and applicable law including

104

the obligation to make Advances pursuant to Section 4.1. As compensation therefor, the Trustee shall be entitled to all funds relating to the Mortgage Loans that the Master Servicer would have been entitled to charge to the Certificate Account or Distribution Account if the Master Servicer had continued to act hereunder. Notwithstanding the foregoing, if the Trustee has become the successor to the Master Servicer in accordance with Section 7.1 hereof, the Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to Section 4.1 hereof or if it is otherwise unable to so act appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder. Any successor to the Master Servicer shall be an institution which is a FNMA and FHLMC approved seller/servicer in good standing, which has a net worth of at least $10,000,000, and which is willing to service the Mortgage Loans and executes and delivers to the Depositor and the Trustee an agreement accepting such delegation and assignment, which contains an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Master Servicer (other than liabilities of the Master Servicer under Section 6.3 hereof incurred prior to termination of the Master Servicer under Section 7.1), with like effect as if originally named as a party to this Agreement; and provided further that each Rating Agency acknowledges that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced, as a result of such assignment and delegation. The Trustee shall provide written notice to the Depositor of such successor pursuant to this Section. The successor to the Master Servicer shall provide to the Depositor in writing, fifteen (15) days prior to the effective date of such appointment, and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to a replacement master servicer. The Trustee shall not resign as servicer until a successor servicer has been appointed and has accepted such appointment. Pending appointment of a successor to the Master Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so acting, shall, subject to Section 3.4 hereof, act in such capacity as provided above. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of the Master Servicing Fee permitted the Master Servicer hereunder. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the Master Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

Any successor to the Master Servicer as master servicer shall give notice to the Mortgagors of such change of servicer and shall, during the term of its service as master servicer maintain in force the policy or policies that the Master Servicer is required to maintain pursuant to Section 3.17.

105

In connection with the termination or resignation of the Master Servicer hereunder, either (i) the successor Master Servicer, including the Trustee if the Trustee is acting as successor Master Servicer, shall represent and warrant that it is a member of MERS in good standing and shall agree to comply in all material respects with the rules and procedures of MERS in connection with the servicing of the Mortgage Loans that are registered with MERS, or (ii) the predecessor Master Servicer shall cooperate with the successor Master Servicer either (x) in causing MERS to execute and deliver an assignment of Mortgage in recordable form to transfer the Mortgage from MERS to the Trustee and to execute and deliver such other notices, documents and other instruments as may be necessary or desirable to effect a transfer of such Mortgage Loan or servicing of such mortgage Loan on the MERS® System to the successor Master Servicer or (y) in causing MERS to designate on the MERS® System the successor Master Servicer as the servicer of such Mortgage Loan. The predecessor Master Servicer shall file or cause to be filed any such assignment in the appropriate recording office. The successor Master Servicer shall cause such assignment to be delivered to the Trustee promptly upon receipt of the original with evidence of recording thereon or a copy certified by the public recording office in which such assignment was recorded.

SECTION 7.3 Notification to Certificateholders.

	(a)	Upon any termination of or appointment of a successor to the Master Servicer, the Trustee shall give prompt written notice thereof to Certificateholders and to each Rating Agency.

	(b)	Within 60 days after the occurrence of any Event of Default, the Trustee shall transmit by mail to all Certificateholders notice of each such Event of Default hereunder known to the Trustee, unless such Event of Default shall have been cured or waived.

ARTICLE VIII
CONCERNING THE TRUSTEE

SECTION 8.1 Duties of Trustee.

The Trustee, prior to the occurrence of an Event of Default of which a Responsible Officer of the Trustee has actual knowledge and after the curing of all Events of Default that may have occurred, shall undertake to perform such duties and only such duties as are specifically set forth in this Agreement. In case an Event of Default of which a Responsible Officer of the Trustee has actual knowledge has occurred and remains uncured, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee that are specifically required to be furnished pursuant to any provision of this Agreement shall examine them to determine whether they are in the form required by this Agreement; provided, however, that the Trustee shall not be responsible for the accuracy or content of any such resolution, certificate, statement,

106

opinion, report, document, order or other instrument. If any such instrument is found not to conform in any material respect to the requirements of this Agreement, the Trustee shall notify the Certificateholders of such instrument in the event that the Trustee, after so requesting, does not receive a satisfactorily corrected instrument.

The Trustee is hereby directed to execute and deliver to The Depository Trust Company the Issuer Letter of Representations dated as of the Closing Date on behalf of the trust created hereunder. The Depositor and the Master Servicer acknowledge and agree that the Trustee is executing and delivering the Issuer Letter of Representations on behalf of the trust created hereunder and shall do so solely in its capacity as Trustee and not in its individual capacity.

No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that:

		(i)	unless an Event of Default of which a Responsible Officer of the Trustee has actual knowledge shall have occurred and be continuing, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement which it believed in good faith to be genuine and to have been duly executed by the proper authorities respecting any matters arising hereunder;

		(ii)	the Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be finally proven that the Trustee was negligent in ascertaining the pertinent facts;

		(iii)	the Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of Holders of Certificates evidencing not less than 25% of the Voting Rights of Certificates relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Agreement;

		(iv)	the Trustee shall not be required to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or the exercise of any of its rights or powers if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not assured to it, and none of the provisions contained in this Agreement shall in any event require the Trustee to perform, or be responsible for the manner of

107

		performance of, any of the obligations of the Master Servicer under this Agreement except during such time, if any, as the Trustee shall be the successor to, and be vested with the rights, duties, powers and privileges of, the Master Servicer; and

	(v)	without limiting the generality of this Section 8.1, the Trustee shall have no duty (A) to see to any recording, filing, or depositing of this Agreement or any agreement referred to herein or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of any such recording or filing or deposit or to any rerecording, refiling or redepositing of any thereof, (B) to see to any insurance, (C) to see to the payment or discharge of any tax, assessment, or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Trust Fund other than from funds available in the Distribution Account (D) to confirm or verify the contents of any reports or certificates of the Servicer delivered to the Trustee pursuant to this Agreement believed by the Trustee to be genuine and to have been signed or presented by the proper party or parties.

If such corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.6 the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

The entity serving as Trustee may have normal banking and trust relationships with the Depositor and its affiliates or the Master Servicer and its affiliates; provided, however, that such entity cannot be an affiliate of the Master Servicer other than the Trustee in its role as successor to the Master Servicer.

SECTION 8.7 Resignation and Removal of Trustee.

The Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice of resignation to the Depositor and the Master Servicer and each Rating Agency not less than 60 days before the date specified in such notice when, subject to Section 8.8, such resignation is to take effect, and acceptance by a successor trustee in accordance with Section 8.8 meeting the qualifications set forth in Section 8.6. If no successor trustee meeting such qualifications shall have been so appointed and have accepted appointment within 30 days after the giving of such notice or resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee.

As a condition to the effectiveness of any such resignation, at least 15 calendar days prior to the effective date of such resignation, the Trustee shall provide (x) written notice to the Depositor of any successor pursuant to this Section and (y) in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to the resignation of the Trustee.

111

avoided by the appointment of a different trustee and (C) the Trustee fails to indemnify the Trust Fund against such tax, or (iv) during the period that the Depositor is required to file Exchange Act Reports with respect to the Trust Fund, the Trustee fails to comply with its obligations under the last sentence of Section 7.1, Section 8.9 or Article X and such failure is not remedied within the lesser of ten (10) calendar days or such period in which the applicable Exchange Act Report can be filed timely (without taking into account any extensions), then, in the case of clauses (i) through (iii), then the Depositor or the Master Servicer may remove the Trustee and appoint a successor trustee by written instrument, in triplicate, one copy of which instrument shall be delivered to the Trustee, one copy of which shall be delivered to the Master Servicer and one copy to the successor trustee.

The Holders of Certificates entitled to at least 51% of the Voting Rights may at any time remove the Trustee and appoint a successor trustee by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered by the successor Trustee to the Master Servicer, one complete set to the Trustee so removed and one complete set to the successor so appointed. Notice of any removal of the Trustee shall be given to each Rating Agency by the Successor Trustee.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.7 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.8 hereof.

SECTION 8.8 Successor Trustee.

Any successor trustee appointed as provided in Section 8.7 hereof shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee and the Master Servicer an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee herein. The Depositor, the Master Servicer and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties, and obligations.

No successor trustee shall accept appointment as provided in this Section 8.8 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 8.6 hereof and its appointment shall not adversely affect the then current rating of the Certificates.

Upon acceptance of appointment by a successor trustee as provided in this Section 8.8, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates. If the Depositor fails to mail such notice within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Depositor.

112

SECTION 8.9 Merger or Consolidation of Trustee.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be eligible under the provisions of Section 8.6 hereof without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

The Trustee shall provide (x) written notice to the Depositor of any successor due to merger or consolidation of the trustee pursuant to this Section within five (5) days of the effectiveness of such merger or consolidation and (y) in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to a replacement Trustee.

SECTION 8.10 Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Master Servicer and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust Fund or any part thereof, whichever is applicable, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider necessary or desirable. If the Master Servicer shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.6 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 8.8.

Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

		(i)	To the extent necessary to effectuate the purposes of this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the

113

			Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the applicable Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

		(ii)	No trustee hereunder shall be held personally liable by reason of any act or omission of any other trustee hereunder and such appointment shall not, and shall not be deemed to, constitute any such separate trustee or co- trustee as agent of the Trustee;

		(iii)	The Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee; and

		(iv)	The Master Servicer, and not the Trustee, shall be liable for the payment of reasonable compensation, reimbursement and indemnification to any such separate trustee or co-trustee.

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the separate trustees and co-trustees, when and as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article VIII. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the Master Servicer and the Depositor.

Any separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

SECTION 8.11 Tax Matters.

It is intended that the assets with respect to which each REMIC election is to be made, as set forth in the preliminary statement shall constitute, and that the conduct of matters relating to such assets shall be such as to qualify such assets as, a “real estate mortgage investment conduit” as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Trustee covenants and agrees that it shall act as agent (and the Trustee is hereby appointed to act as agent) on behalf of any such REMIC and that in such capacity it shall: (a) prepare and file, or cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return (Form 1066 or any successor form adopted by the Internal Revenue

114

Service) and prepare and file or cause to be prepared and filed with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to any such REMIC, containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish or cause to be furnished to Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby; (b) within thirty days of the Closing Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the Holders of the Certificates may contact for tax information relating thereto, together with such additional information as may be required by such Form, and update such information at the time or times in the manner required by the Code; (c) make or cause to be made elections that such assets be treated as a REMIC on the federal tax return for its first taxable year (and, if necessary, under applicable state law); (d) prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and to the Internal Revenue Service and, if necessary, state tax authorities, all information returns and reports as and when required to be provided to them in accordance with the REMIC Provisions, including without limitation, the calculation of any original issue discount using the prepayment assumption; (e) provide information necessary for the computation of tax imposed on the transfer of a Residual Certificate to a Person that is not a Permitted Transferee, or an agent (including a broker, nominee or other middleman) of a Non-Permitted Transferee, or a pass-through entity in which a Non-Permitted Transferee is the record holder of an interest (the reasonable cost of computing and furnishing such information may be charged to the Person liable for such tax); (f) to the extent that they are under its control conduct matters relating to such assets at all times that any Certificates are outstanding so as to maintain the status as a REMIC under the REMIC Provisions; (g) not knowingly or intentionally take any action or omit to take any action that would cause the termination of any REMIC status; (h) pay, from the sources specified in the last paragraph of this Section 8.11, the amount of any federal or state tax, including prohibited transaction taxes as described below, imposed on any such REMIC prior to its termination when and as the same shall be due and payable (but such obligation shall not prevent the Trustee or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Trustee from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings); (i) ensure that federal, state or local income tax or information returns shall be signed by the Trustee or such other person as may be required to sign such returns by the Code or state or local laws, regulations or rules; (j) maintain records relating to any such REMIC, including but not limited to the income, expenses, assets and liabilities thereof and the fair market value and adjusted basis of the assets determined at such intervals as may be required by the Code, as may be necessary to prepare the foregoing returns, schedules, statements or information; and (k) as and when necessary and appropriate, represent any such REMIC in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing authority, request an administrative adjustment as to any taxable year of any such REMIC, enter into settlement agreements with any governmental taxing agency, extend any statute of limitations relating to any tax item of any such REMIC, and otherwise act on behalf of any such REMIC in relation to any tax matter or controversy involving it.

In order to enable the Trustee to perform its duties as set forth herein, the Depositor shall provide, or cause to be provided, to the Trustee within ten (10) days after the Closing Date all information or data that the Trustee requests in writing and determines to be relevant for tax

115

purposes to the valuations and offering prices of the Certificates, including, without limitation, the price, yield, prepayment assumption and projected cash flows of the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide to the Trustee promptly upon written request therefor, any such additional information or data that the Trustee may, from time to time, reasonably request in order to enable the Trustee to perform its duties as set forth herein. The Depositor hereby indemnifies the Trustee for any losses, liabilities, damages, claims or expenses of the Trustee arising from any errors or miscalculations of the Trustee that result from any failure of the Depositor to provide, or to cause to be provided, accurate information or data to the Trustee on a timely basis.

In the event that any tax is imposed on “prohibited transactions” of any REMIC as defined in Section 860F(a)(2) of the Code, on the “net income from foreclosure property” of any REMIC as defined in Section 860G(c) of the Code, on any contribution to any REMIC after the Startup Day pursuant to Section 860G(d) of the Code, or any other tax is imposed, if not paid as otherwise provided for herein, such tax shall be paid by (i) the Trustee, if any such other tax arises out of or results from a breach by the Trustee of any of its obligations under this Agreement which breach was caused by its negligence or willful misconduct, (ii) the Master Servicer, in the case of any such minimum tax, or if such tax arises out of or results from a breach by the Master Servicer of any of their obligations under this Agreement, (iii) the Seller, if any such tax arises out of or results from the Seller’s obligation to repurchase a Mortgage Loan pursuant to Section 2.2 or 2.3 or (iv) in all other cases, or in the event that the Trustee, the Master Servicer or the Seller fails to honor its obligations under the preceding clauses (i), (ii) or (iii), any such tax will be paid with amounts otherwise to be distributed to the Certificateholders, as provided in Section 3.8(b) .

Each Class I-A-1 Certificate shall be treated as representing not only ownership of regular interests in the Upper Tier REMIC, but also ownership of an interest in the Corridor Contract. For tax purposes, the Corridor Contract shall be deemed to have a value of $213,000 as of the Closing Date.

Each Class I-A-6 Certificate shall be treated as representing not only ownership of regular interests in the Upper Tier REMIC, but also ownership of an interest in the Yield Supplement Account. For tax purposes, the Corridor Contract shall be deemed to have a value of $1,050,000 as of the Closing Date.

ARTICLE IX

Subject to Section 9.3, the obligations and responsibilities of the Depositor, the Master Servicer and the Trustee created hereby with respect to the Trust Fund shall terminate upon the earlier of (a) the purchase by the Master Servicer of all Mortgage Loans (and REO Properties) remaining in the Trust Fund at the price equal to the sum of (i) 100% of the Stated Principal Balance of each Mortgage Loan (other than a Mortgage Loan that has been foreclosed and subject to clause (ii)) plus one month’s accrued interest thereon at the applicable Adjusted Mortgage Rate, (ii) the lesser of (x) the appraised value of any REO Property as determined by

The Master Servicer will deposit the funds for such purchase into the Certificate Account pursuant to Section 3.5(b)(viii).

SECTION 9.2 Final Distribution on the Certificates.

If on any Determination Date, the Master Servicer determines that there are no Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other than the funds in the Certificate Account, the Master Servicer shall direct the Trustee promptly to send a final distribution notice to each Certificateholder. If the Master Servicer elects to terminate the Trust Fund pursuant to clause (a) of Section 9.1, at least 20 days prior to the date notice is to be mailed to the affected Certificateholders, the Master Servicer shall notify the Depositor and the Trustee of the date the Master Servicer intends to terminate the Trust Fund and of the applicable repurchase price of the Mortgage Loans and REO Properties.

Notice of any termination of the Trust Fund, specifying the Distribution Date on which Certificateholders may surrender their Certificates for payment of the final distribution and cancellation, shall be given promptly by the Trustee by letter to Certificateholders mailed not earlier than the 10th day and no later than the 15th day of the month next preceding the month of such final distribution. Any such notice shall specify (a) the Distribution Date upon which final distribution on the Certificates will be made upon presentation and surrender of Certificates at the office therein designated, (b) the amount of such final distribution, (c) the location of the office or agency at which such presentation and surrender must be made, and (d) that the Record Date otherwise applicable to such Distribution Date is not applicable, distributions being made only upon presentation and surrender of the Certificates at the office therein specified. The Master Servicer will give such notice to each Rating Agency at the time such notice is given to Certificateholders.

In the event such notice is given, the Master Servicer shall cause all funds in the Certificate Account to be remitted to the Trustee for deposit in the applicable subaccounts of the Distribution Account on the Business Day prior to the applicable Distribution Date in an amount equal to the final distribution in respect of the Certificates. Upon such final deposit with respect

117

to the Trust Fund and the receipt by the Trustee of a Request for Release therefor, the Trustee shall promptly release to the Master Servicer the Mortgage Files for the Mortgage Loans.

Upon presentation and surrender of the Certificates, the Trustee shall cause to be distributed to the Certificateholders of each Class, in the order set forth in Section 4.2 hereof, on the final Distribution Date, in the case of the Certificateholders, in proportion to their respective Percentage Interests, with respect to Certificateholders of the same Class, an amount equal to (i) as to each Class of Regular Certificates, the Class Certificate Balance thereof plus accrued interest thereon in the case of an interest bearing Certificate, and (ii) as to the Residual Certificates, the amount, if any, which remains on deposit in the Distribution Account (other than the amounts retained to meet claims) after application pursuant to clause (i) above.

In the event that any affected Certificateholders shall not surrender Certificates for cancellation within six months after the date specified in the above mentioned written notice, the Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice all the applicable Certificates shall not have been surrendered for cancellation, the Trustee may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets which remain a part of the Trust Fund. If within one year after the second notice all Certificates shall not have been surrendered for cancellation, the Holders of each of the Class I-A-R Certificates shall be entitled to all unclaimed funds and other assets of the Trust Fund, held for distribution to such Certificateholders, which remain subject hereto.

SECTION 9.3 Additional Termination Requirements.

(a)	In the event the Master Servicer exercises its purchase option as provided in Section 9.1, the Trust Fund and each REMIC created hereunder shall be terminated in accordance with the following additional requirements, unless the Trustee has been supplied with an Opinion of Counsel, at the expense of the Master Servicer, to the effect that the failure to comply with the requirements of this Section 9.3 will not (i) result in the imposition of taxes on “prohibited transactions” on any REMIC as defined in Section 860F of the Code, or (ii) cause any REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding:

	(I)	Within 90 days prior to the final Distribution Date set forth in the notice given by the Master Servicer under Section 9.2, the Master Servicer shall prepare and the Trustee, at the expense of the “tax matters person,” shall adopt a plan of complete liquidation within the meaning of Section 860F(a)(4) of the Code for each REMIC created hereunder which, as evidenced by an Opinion of Counsel addressed to the Trustee (which opinion shall not be an expense of the Trustee or the Tax Matters Person), meets the requirements of a qualified liquidation; and

118

	(II)	Within 90 days after the time of adoption of such plans of complete liquidation, the Trustee shall sell all of the assets of the Trust Fund to the Master Servicer for cash in accordance with Section 9.1.

Prior to March 30th of each year, commencing in 2008 (or such earlier date as may be required by the Exchange Act), the Depositor shall prepare and file on behalf of the Trust Fund a Form 10-K, in form and substance as required by the Exchange Act.

If the Item 1119 Parties listed on Exhibit P have changed since the Closing Date, no later than March 1 of each year, the Depositor shall provide each of the Master Servicer (and the Master Servicer shall provide any Subservicer) and the Trustee with an updated Exhibit P setting forth the Item 1119 Parties.

SECTION 10.5 Xxxxxxxx-Xxxxx Certification.

Each Form 10-K shall include a certification (the “Xxxxxxxx-Xxxxx Certification”) required by Rules 13a-14(d) and 15d-14(d) under the Exchange Act (pursuant to Section 302 of the Xxxxxxxx-Xxxxx Act of 2002 and the rules and regulations of the SEC promulgated thereunder (including any interpretations thereof by the SEC’s staff)).

121

Certification”), substantially in the form attached hereto as Exhibit N-1 (in the case of a Subservicer) and Exhibit N-2 (in the case of the Trustee), unless such other form is mutually agreed upon, on which the Certifying Person, the entity for which the Certifying Person acts as an officer, and such entity’s officers, directors and Affiliates (collectively with the Certifying Person, “Certification Parties”) can reasonably rely. The senior officer in charge of the servicing function of the Master Servicer shall serve as the Certifying Person on behalf of the Trust Fund. Neither the Master Servicer nor the Depositor will request delivery of a certification under this clause unless the Depositor is required under the Exchange Act to file an annual report on Form 10-K with respect to the Trust Fund. In the event that prior to the filing date of the Form 10-K in March of each year, a Responsible Officer of the Trustee or the Depositor has actual knowledge of information material to the Xxxxxxxx-Xxxxx Certification, the Trustee or the Depositor, as the case may be, shall promptly notify the Master Servicer and the Depositor. The respective parties hereto agree to cooperate with all reasonable requests made by any Certifying Person or Certification Party in connection with such Person’s attempt to conduct any due diligence that such Person reasonably believes to be appropriate in order to allow it to deliver any Xxxxxxxx-Xxxxx Certification or portion thereof with respect to the Trust Fund.

Prior to January 31 of the first year in which the Depositor is able to do so under applicable law, the Depositor shall file a Form 15 relating to the automatic suspension of reporting in respect of the Trust Fund under the Exchange Act.

SECTION 10.7 Report on Assessment of Compliance and Attestation.

	(a)	On or before March 15 of each calendar year, in which a Form 10-K is required to be filed on behalf of the Trust Fund, commencing in 2008:

		(i) Each of the Master Servicer and the Trustee shall deliver to the Depositor and the Master Servicer a report (in form and substance reasonably satisfactory to the Depositor) regarding the Master Servicer’s or the Trustee’s, as applicable, assessment of compliance with the Servicing Criteria during the immediately preceding calendar year, as required under Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122 of Regulation AB. Such report shall be signed by an authorized officer of such Person and shall address each of the Servicing Criteria specified on a certification substantially in the form of Exhibit O hereto, unless such other form is mutually agreed upon and delivered to the Depositor concurrently with the execution of this Agreement. To the extent any of the Servicing Criteria are not applicable to such Person, with respect to asset-backed securities transactions taken as a whole involving such Person and that are backed by the same asset type backing the Certificates, such report shall include such a statement to that effect. The Depositor and the Master Servicer, and each of their respective officers and directors shall be entitled to rely upon each such servicing criteria assessment.

		(ii) Each of the Master Servicer and the Trustee shall deliver to the Depositor and the Master Servicer a report of a registered public accounting firm

122


		reasonably acceptable to the Depositor that attests to, and reports on, the assessment of compliance made by Master Servicer or the Trustee, as applicable, and delivered pursuant to the preceding paragraphs. Such attestation shall be in accordance with Rules 1-02(a)(3) and 2-02(g) of Regulation S-X under the Securities Act and the Exchange Act, including, without limitation that in the event that an overall opinion cannot be expressed, such registered public accounting firm shall state in such report why it was unable to express such an opinion. Such report must be available for general use and not contain restricted use language. To the extent any of the Servicing Criteria are not applicable to such Person, with respect to asset-backed securities transactions taken as a whole involving such Person and that are backed by the same asset type backing the Certificates, such report shall include such a statement that that effect.

		(iii) The Master Servicer shall cause each Subservicer that is a Reporting Subcontractor engaged by it to deliver to the Depositor an assessment of compliance and accountants’ attestation as and when provided in paragraphs (a) and (b) of this Section 10.7.

	(b)	Each assessment of compliance provided by a Subservicer pursuant to Section 10.7(a)(iii) shall address each of the Servicing Criteria specified on a certification substantially in the form of Exhibit O hereto delivered to the Depositor concurrently with the execution of this Agreement or, in the case of a Subservicer subsequently appointed as such, on or prior to the date of such appointment. An assessment of compliance provided by a Subcontractor pursuant to Section 10.7(a)(iii) or (iv) need not address any elements of the Servicing Criteria other than those specified by the Master Servicer or the Trustee, as applicable, pursuant to Section 10.7(a)(i).

		SECTION 10.8 Use of Subservicers and Subcontractors.

	(a)	The Master Servicer shall cause any Subservicer that is a Reporting Subcontractor used by the Master Servicer (or by any Subservicer) for the benefit of the Depositor to comply with the provisions of Section 3.16 and this Article X to the same extent as if such Subservicer were the Master Servicer (except with respect to the Master Servicer’s duties with respect to preparing and filing any Exchange Act Reports or as the Certifying Person). The Master Servicer shall be responsible for obtaining from each Subservicer that is a Reporting Subcontractor and delivering to the Depositor any servicer compliance statement required to be delivered by such Subservicer under Section 3.16, any assessment of compliance and attestation required to be delivered by such Subservicer under Section 10.7 and any certification required to be delivered to the Certifying Person under Section 10.5 as and when required to be delivered. As a condition to the

123

		succession to any Subservicer as subservicer under this Agreement by any Person (i) into which such Subservicer may be merged or consolidated, or (ii) which may be appointed as a successor to any Subservicer, the Master Servicer shall provide to the Depositor, at least fifteen (15) calendar days prior to the effective date of such succession or appointment, (x) written notice to the Depositor of such succession or appointment and (y) in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.2 of Form 8-K.

	(b)	It shall not be necessary for the Master Servicer or any Subservicer to seek the consent of the Depositor or any other party hereto to the utilization of any Subcontractor. The Master Servicer shall promptly upon request provide to the Depositor (or any designee of the Depositor, such as the Master Servicer or administrator) a written description (in form and substance satisfactory to the Depositor) of the role and function of each Subcontractor utilized by such Person (or in the case of the Master Servicer or any Subservicer), specifying (i) the identity of each such Subcontractor, (ii) which (if any) of such Subcontractors are “participating in the servicing function” within the meaning of Item 1122 of Regulation AB, and (iii) which elements of the Servicing Criteria will be addressed in assessments of compliance provided by each Subcontractor who is a Reporting Subcontractor identified pursuant to clause (ii) of this paragraph.

		As a condition to the utilization of any Subcontractor determined to be a Reporting Subcontractor, the Master Servicer shall cause any such Subcontractor used by such Person (or in the case of the Master Servicer or any Subservicer) for the benefit of the Depositor to comply with the provisions of Sections 10.7 and 10.9 of this Agreement to the same extent as if such Subcontractor were the Master Servicer (except with respect to the Master Servicer’s duties with respect to preparing and filing any Exchange Act Reports or as the Certifying Person). The Master Servicer shall be responsible for obtaining from each Subcontractor and delivering to the Depositor and the Master Servicer, any assessment of compliance and attestation required to be delivered by such Subcontractor under Section 10.7, in each case as and when required to be delivered.

SECTION 10.9 Amendments.

In the event the parties to this Agreement desire to further clarify or amend any provision of this Article X, this Agreement shall be amended to reflect the new agreement between the parties covering matters in this Article X pursuant to Section 11.1, which amendment shall not require any Opinion of Counsel or Rating Agency confirmations or the consent of any Certificateholder. If, during the period that the Depositor is required to file Exchange Act Reports with respect to the Trust Fund, the Master Servicer is no longer an Affiliate of the Depositor, the Depositor shall assume the obligations and responsibilities of the Master Servicer in this Article X with respect to the preparation and filing of the Exchange Act Reports and/or acting as the Certifying Person, if the Depositor has received indemnity from such successor Master Servicer satisfactory to the

124

Depositor, and such Master Servicer has agreed to provide a Xxxxxxxx-Xxxxx Certification to the Depositor substantially in the form of Exhibit Q.

ARTICLE XI
MISCELLANEOUS PROVISIONS

SECTION 11.1 Amendment.

This Agreement may be amended from time to time by the Depositor, the Master Servicer and the Trustee without the consent of any of the Certificateholders (i) to cure any ambiguity or mistake, (ii) to correct any defective provision herein or to supplement any provision herein which may be inconsistent with any other provision herein, (iii) to add to the duties of the Depositor, the Seller or the Master Servicer, (iv) to add any other provisions with respect to matters or questions arising hereunder or (v) to modify, alter, amend, add to or rescind any of the terms or provisions contained in this Agreement; provided that any action pursuant to clauses (iv) or (v) above shall not, as evidenced by an Opinion of Counsel delivered to the Trustee (which Opinion of Counsel shall not be an expense of the Trustee or the Trust Fund), adversely affect in any material respect the interests of any Certificateholder; provided, however, that the amendment shall not be deemed to adversely affect in any material respect the interests of the Certificateholders if the Person requesting the amendment obtains a letter from each Rating Agency stating that the amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates; it being understood and agreed that any such letter in and of itself will not represent a determination as to the materiality of any such amendment and will represent a determination only as to the credit issues affecting any such rating. The Trustee, the Depositor and the Master Servicer also may at any time and from time to time amend this Agreement without the consent of the Certificateholders to modify, eliminate or add to any of its provisions to such extent as shall be necessary or helpful to (i) maintain the qualification of any REMIC established hereunder as a REMIC under the Code, (ii) avoid or minimize the risk of the imposition of any tax on any REMIC established hereunder pursuant to the Code that would be a claim at any time prior to the final redemption of the Certificates or (iii) comply with any other requirements of the Code, provided that the Trustee has been provided an Opinion of Counsel, which opinion shall be an expense of the party requesting such opinion but in any case shall not be an expense of the Trustee or the Trust Fund, to the effect that such action is necessary or helpful to, as applicable, (i) maintain such qualification, (ii) avoid or minimize the risk of the imposition of such a tax or (iii) comply with any such requirements of the Code.

This Agreement may also be amended from time to time by the Depositor, the Master Servicer and the Trustee with the consent of the Holders of a Majority in Interest of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) adversely affect in any material respect the interests of the Holders of any Class of Certificates in a manner other than as described in (i), without the consent of the Holders of Certificates of such Class evidencing, as to such Class, Percentage Interests aggregating 66%, or (iii) reduce the aforesaid percentages of Certificates the Holders of which are required to consent to any such amendment,

125

without the consent of the Holders of all such Certificates then outstanding. In addition, the permitted activities of the Trust under this Agreement cannot be significantly modified without the approval of Holders of Certificates evidencing a Majority in Interest.

Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel, which opinion shall not be an expense of the Trustee or the Trust Fund, to the effect that such amendment will not cause the imposition of any tax on any REMIC established hereunder or the Certificateholders or cause any REMIC established hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding.

Promptly after the execution of any amendment to this Agreement requiring the consent of Certificateholders, the Trustee shall furnish written notification of the substance or a copy of such amendment to each Certificateholder and each Rating Agency.

It shall not be necessary for the consent of Certificateholders under this Section to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe.

Nothing in this Agreement shall require the Trustee to enter into an amendment without receiving an Opinion of Counsel (which Opinion shall not be an expense of the Trustee or the Trust Fund), satisfactory to the Trustee that (i) such amendment is permitted and is not prohibited by this Agreement and that all requirements for amending this Agreement have been complied with; and (ii) either (A) the amendment does not adversely affect in any material respect the interests of any Certificateholder or (B) the conclusion set forth in the immediately preceding clause (A) is not required to be reached pursuant to this Section 11.1.

SECTION 11.2 Recordation of Agreement; Counterparts.

This Agreement is subject to recordation in all appropriate public offices for real property records in all the counties or other comparable jurisdictions in which any or all of the properties subject to the Mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Master Servicer at its expense, but only upon direction a majority of the Certificateholders to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed (by facsimile or otherwise) simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument.

The Depositor, for the benefit of the Certificateholders, shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Trust Fund, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement.

No Certificateholder shall have any right to vote (except as provided herein) or in any manner otherwise control the operation and management of the Trust Fund, or the obligations of the parties hereto, nor shall anything herein set forth or contained in the terms of the Certificates be construed so as to constitute the Certificateholders from time to time as partners or members of an association; nor shall any Certificateholder be under any liability to any third party by reason of any action taken by the parties to this Agreement pursuant to any provision hereof.

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of an Event of Default and of the continuance thereof, as herein provided, and unless the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates shall also have made written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses, and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Agreement, except in the manner herein provided and for the common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 11.8, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Distribution Account for payment hereunder and that the Trustee is not liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits, obligations and duties evidenced thereby, and the rights, duties and immunities of the Trustee.

Pursuant to the terms of the Agreement, a distribution will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following (the “Distribution Date”), commencing on the first Distribution Date specified on the face hereof, to the Person in whose name this Certificate is registered at the close of business on the applicable Record Date in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to Holders of Certificates of the Class to which this Certificate belongs on such Distribution Date pursuant to the Agreement. The Record Date applicable to each Distribution Date is the last Business Day of the month next preceding the month of such Distribution Date.

Distributions on this Certificate shall be made by wire transfer of immediately available funds to the account of the Holder hereof at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have so notified the Trustee in writing at least five Business Days prior to the related Record Date and such Certificateholder shall satisfy the conditions to receive such form of payment set forth in the Agreement, or, if not, by check mailed by first class mail to the address of such Certificateholder appearing in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the Corporate Trust Office or such other location specified in the notice to Certificateholders of such final distribution.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Trustee and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer and the Trustee with the consent of the Holders of Certificates affected by such amendment evidencing the requisite Percentage Interest, as provided in the Agreement. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of

D-1

this Certificate and of any Certificate issued upon the transfer hereof or in exchange therefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register of the Trustee upon surrender of this Certificate for registration of transfer at the Corporate Trust Office or the office or agency maintained by the Trustee in New York, New York, accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Certificate Registrar duly executed by the holder hereof or such holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest in the Trust Fund will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

No service charge will be made for any such registration of transfer or exchange, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Depositor, the Master Servicer and the Trustee and any agent of the Depositor or the Trustee may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Depositor, the Trustee, nor any such agent shall be affected by any notice to the contrary.

On any Distribution Date on which the aggregate of the Pool Principal Balances of all of the Mortgage Pools is less than 10% of the aggregate Cut-off Date Pool Principal Balance of all of the Mortgage Pools, the Master Servicer will have the option to repurchase, in whole, from the Trust Fund all remaining Mortgage Loans and all property acquired in respect of the Mortgage Loans in the Mortgage Pools at a purchase price determined as provided in the Agreement. In the event that no such optional termination occurs, the obligations and responsibilities created by the Agreement will terminate upon the later of the maturity or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or the disposition of all property in respect thereof and the distribution to Certificateholders of all amounts required to be distributed pursuant to the Agreement. In no event, however, will the trust created by the Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement.

Any term used herein that is defined in the Agreement shall have the meaning assigned in the Agreement, and nothing herein shall be deemed inconsistent with that meaning.

STATE OF	)
	) ss.:
COUNTY OF	)

The undersigned, being first duly sworn, deposes and says as follows:

1. The undersigned is an officer of __________, the proposed Transferee of an Ownership Interest in a Class I-A-R Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement, (the “Agreement”), relating to the above-referenced Series, by and among First Horizon Asset Securities Inc., as depositor (the “Depositor”), First Horizon Home Loans, a division of First Tennessee Bank National Association, as master servicer, and The Bank of New York, as trustee. Capitalized terms used, but not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee.

2. The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest in the Certificate either (i) for its own account or (ii) as nominee, trustee or agent for another Person and has attached hereto an affidavit from such Person in substantially the same form as this affidavit. The Transferee has no knowledge that any such affidavit is false. The Transferee does not hold REMIC residual interests as nominee to facilitate the clearance and settlement of such interests through electronic book-entry changes in accounts of participating organizations.

3. The Transferee has been advised of, and understands that (i) a tax may be imposed on Transfers of the Certificate to Persons that are not Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent transferee furnished to such Person an affidavit that such subsequent transferee is a Permitted Transferee and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false.

4. The Transferee has been advised of, and understands that a tax may be imposed on a “pass-through entity” holding the Certificate if at any time during the taxable year of the pass-through entity a Person that is not a Permitted Transferee is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is a Permitted Transferee and the pass-through entity does not have actual knowledge that such affidavit is false. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a

H-1

partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.)

5. The Transferee has reviewed the provisions of Section 5.2(c) of the Agreement (attached hereto as Exhibit 2 and incorporated herein by reference) and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 5.2(c) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

6. The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and in connection with any Transfer by a Person for whom the Transferee is acting as nominee, trustee or agent, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a certificate substantially in the form set forth as Exhibit I to the Agreement (a “Transferor Certificate”) to the effect that such Transferee has no actual knowledge that the Person to which the Transfer is to be made is not a Permitted Transferee.

7. The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Certificate.

8. The Transferee’s taxpayer identification number is ______.

9. The Transferee is either a U.S. Person as defined in Code Section 7701(a)(30) or the Transferee has furnished the Transferor a properly completed Internal Revenue Service Form W-8ECI..

10. The Transferee is aware that the Certificate may represent one or more interests in a “noneconomic residual interest” within the meaning of Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax.

11. The Transferee is not an employee benefit plan or arrangement subject to Section 406 of ERISA or a plan or arrangement subject to Section 4975 of the Code, nor a person acting on behalf of any such plan or arrangement, nor using the assets of any such plan or arrangement to effect such transfer.

12. The Transferee has historically paid its debts as they came due and the Transferee will continue to pay its debts as they come due in the future; the Transferee understands that, as the holder of the Certificate, the Transferee may incur tax liabilities in excess of any cash flows generated by the Certificate and the Transferee intends to pay taxes associated with holding the Certificate as they become due.

H-2

13. The Transferee is a domestic corporation taxable as a regular corporation for U.S. federal income tax purposes (a “taxable domestic C corporation”) and is not a real estate investment trust, regulated investment company or REMIC. The Transferee will not cause income from the Certificate to be attributable, for U.S. federal income tax purposes, to a non-U.S. permanent establishment or fixed base (within the meaning of an applicable income tax treaty) of the Transferee or another U.S. taxpayer. At the time of the Transfer, and at the close of each of the Transferee’s two fiscal years preceding the year of the Transfer, the Transferee’s gross assets for financial reporting purposes exceeded $10 million (together, the “Asset Requirements”), and the Transferee hereby covenants that any subsequent Transfer of its Ownership Interest in the Certificate will be to another taxable, domestic C corporation satisfying the Asset Requirements

IN WITNESS WHEREOF, the Transferee has caused this instrument to be executed on its behalf, pursuant to authority of its Board of Directors, by its duly authorized officer and its corporate seal to be hereunto affixed, duly attested, this ___ day of _________, 20__.

Certain Definitions

“Ownership Interest”: As to any Certificate, any ownership interest in such Certificate, including any interest in such Certificate as the Holder thereof and any other interest therein, whether direct or indirect, legal or beneficial.

“Permitted Transferee”: Any Person other than (i) the United States, any State or political subdivision thereof, or any agency or instrumentality of any of the foregoing, (ii) a foreign government, International Organization or any agency or instrumentality of either of the foregoing, (iii) an organization (except certain farmers’ cooperatives described in section 521 of the Code) which is exempt from tax imposed by Chapter 1 of the Code (including the tax imposed by section 511 of the Code on unrelated business taxable income) on any excess inclusions (as defined in section 860E(c)(l) of the Code) with respect to any Certificate, (iv) rural electric and telephone cooperatives described in section 1381(a)(2)(C) of the Code, (v) an “electing large partnership” as defined in section 775 of the Code, (vi) a Person that is not (a) a citizen or resident of the United States, (b) a corporation, partnership, or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (c) an estate whose income from sources without the United States is includible in gross income for United States federal income tax purposes regardless of its connection with the conduct of a trade or business within the United States or (d) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust, unless such Person has furnished the transferor and the Trustee with a duly completed Internal Revenue Service Form W-8ECI or any applicable successor form, and (vii) any other Person so designated by the Depositor based upon an Opinion of Counsel that the Transfer of an Ownership Interest in a Certificate to such Person may cause any REMIC created pursuant to the Agreement to fail to qualify as a REMIC at any time that the Certificates (as defined in the Agreement) are outstanding; provided, however, that if a person is classified as a partnership or a disregarded entity under the Code, such person shall only be a Permitted Transferee if all of its beneficial owners are described in subclauses (a), (b), (c) or (d) of clause (vi) and the governing documents of such person prohibits a transfer of any interest in such person to any person described in clause (vi). The terms “United States,” “State” and “International Organization” shall have the meanings set forth in section 7701 of the Code or successor provisions. A corporation will not be treated as an instrumentality of the United States or of any State or political subdivision thereof for these purposes if all of its activities are subject to tax and, with the exception of the Federal Home Loan Mortgage Corporation, a majority of its board of directors is not selected by such government unit.

“Person”: Any individual, corporation, partnership, joint venture, association, bank, joint-stock company, trust (including any beneficiary thereof), unincorporated organization or government or any agency or political subdivision thereof.

Section 5.2(c) of the Agreement

(c) Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Trustee of any change or impending change in its status as a Permitted Transferee.

(ii) No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Trustee shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Trustee under subparagraph (b) above, the Trustee shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee in the form attached hereto as Exhibit H. The Transferee does not hold REMIC residual interests as nominee to facilitate the clearance and settlement of such interests through electronic book-entry changes in accounts of participating organizations.

(iii) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee.

(iv) Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 5.2(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.2(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 5.2(b) and this Section 5.2(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate, and in the case of a Residual Certificate which is also a Private Certificate, either the Rule 144A Letter or the Investment Letter. The Trustee shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so

H-6

recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Permitted Transferee of such Certificate.

(v) The Depositor shall use its best efforts to make available, upon receipt of written request from the Trustee, all information necessary to compute any tax imposed under Section 860E(e) of the Code as a result of a Transfer of an Ownership Interest in a Residual Certificate to any Holder who is not a Permitted Transferee.

The restrictions on Transfers of a Residual Certificate set forth in this Section 5.2(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee or the Master Servicer, to the effect that the elimination of such restrictions will not cause any REMIC created hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is not a Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate which is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.
