(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.

SECTION 3.6 Separate Interest Trust.

(a)

The Seller hereby creates a trust, separate from the Trust, for the benefit of the holders of the Class X Certificates (such trust is referred to herein as the “Separate Interest Trust”) and hereby transfers, assigns and conveys the sum of $1.00 and all of its right, title and interest in and to the Underlying Yield Supplement Amounts into the Separate Interest Trust. The Separate Interest Distribution Account will be an asset of the Separate Interest Trust. The Trustee shall be the trustee of the Separate Interest Trust. The Separate Interest Trust shall not be an asset of the Trust Fund.

(b)	The Trustee shall deposit into the Separate Interest Distribution Account any and all Underlying Yield Supplement Amounts received from time to time in respect of the Underlying Certificates.

SECTION 4.1 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 4.2 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 F (the “Transferor Certificate”) and (i) deliver a letter in substantially the form of either Exhibit G (the “Investment Letter”) or Exhibit H (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 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 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 G or Exhibit H), 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 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 Section 406 of ERISA and Section 4975 of the Code and will not subject the Trustee or the Depositor 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.

(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 E and with a certificate of the proposed transferor in the form attached hereto as Exhibit F.

(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 or the Trustee, to the effect that the elimination of such restrictions will not cause the 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.

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 6.6 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. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 6.6, the Trustee shall resign immediately in the manner and with the effect specified in Section 6.7 hereof. The entity serving as Trustee may have normal banking and trust relationships with the Depositor and its affiliates; provided, however, that such entity cannot be an affiliate of the Depositor.

SECTION 6.7 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 each Rating Agency not less than 60 days before the date specified in such notice when, subject to Section 6.8, such resignation is to take effect, and acceptance by a successor trustee in accordance with Section 6.8 meeting the qualifications set forth in Section 6.6. 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.

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 Depositor, 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 6.7 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 6.8 hereof.

SECTION 6.8 Successor Trustee.

Any successor trustee appointed as provided in Section 6.7 hereof shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee 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 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 6.8 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 6.6 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 6.8, 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.

SECTION 6.9 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 6.6 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 6.10 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 may at the time be located, the Depositor 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 6.10, such powers, duties, obligations, rights and trusts as the Depositor and the Trustee may consider necessary or desirable. If the Depositor shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, 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 6.6 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 6.8.

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 6.10, 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, 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 Trust Fund, 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 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.

TERMINATION

SECTION 7.1 Termination upon Optional Termination of the Underlying Certificates.

Subject to Section 7.3, the obligations and responsibilities of the Depositor and the Trustee created hereby with respect to the Trust Fund shall terminate upon the earlier of (a) the Distribution Date on which the Underlying Certificates are terminated pursuant to Section 9.1 of the Underlying PSA, and (b) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement. In no event shall the trusts created hereby continue beyond the earlier of (i) the expiration of 21 years from the death of the survivor of the descendants of Xxxxxx X. Xxxxxxx, the late Ambassador of the United States to the Court of St. James’s, living on the date hereof, and (ii) the Latest Possible Maturity Date.

SECTION 7.2 Final Distribution on the Certificates.

If on any Determination Date, the Depositor determines that the class certificate balance of the Underlying Certificates will be reduced to zero on the related Distribution Date and there are no other funds or assets in the Trust Fund other than the funds on deposit in, or to be deposited into, the Distribution Account on the related Distribution Date, the Depositor shall direct the Trustee promptly to send a final distribution notice to each Certificateholder.

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. 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 Depositor will give such notice to each Rating Agency at the time such notice is given to Certificateholders.

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 3.2 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 the Class 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 7.3 Additional Termination Requirements.

(a)

In the event that the Underlying Certificates are terminated as provided in Section 7.1, the Trust Fund and the REMIC created hereunder shall be terminated in accordance with the following additional requirement, unless the Trustee has been supplied with an Opinion of Counsel, at the expense of the Depositor, to the effect that the failure to comply with the requirements of this Section 7.3 will not (i) result in the imposition of taxes on “prohibited transactions” on the REMIC created hereunder as defined in Section 860F of the Code, or (ii) cause the REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding:

Within 90 days prior to the final Distribution Date set forth in the notice given by the Trustee under Section 7.2, the Depositor shall prepare, or shall cause to be prepared, 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 the 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.

(b)

The Trustee as agent for the REMIC established hereunder hereby agrees to adopt and sign such a plan of complete liquidation upon the written request of the Depositor, and the receipt of the Opinion of Counsel referred to in Section 7.3(a)(1) and to take such other action in connection therewith as may be reasonably requested by the Depositor.

(c)

By their acceptance of the Certificates, the Holders thereof hereby authorize the Depositor to prepare and the Trustee to adopt and sign plans of complete liquidation.

Such information shall be provided concurrently with the delivering of the Monthly Statements specified in Section 3.4, commencing with the first such Monthly Statements due not less than five (5) Business Days following such request.

The Trustee shall have no liability to the Certificateholders, the Trust Fund or the Depositor with respect to any failure to properly prepare or file any of Form 10-D to the extent that such failure is not the result of any gross negligence, bad faith or willful misconduct on its part. For avoidance of doubt, the Trustee shall have no liability whatsoever under the Securities Act or the Exchange Act

The senior officer in charge of securitization of the Depositor shall serve as the Certifying Person on behalf of the Trust Fund. The Depositor will not 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, the Trustee has actual knowledge of information material to the Xxxxxxxx-Xxxxx Certification, the Trustee shall promptly notify 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.

The Depositor and each of its officers and directors shall be entitled to rely upon each such servicing criteria assessment.

(ii) The Trustee shall deliver to the Depositor a report of a registered public accounting firm reasonably acceptable to the Depositor that attests to, and reports on, the assessment of compliance made by the Trustee 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.

MISCELLANEOUS PROVISIONS

SECTION 9.1 Amendment.

This Agreement may be amended from time to time by the Depositor 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, (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 and the Depositor 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 the REMIC established hereunder as a REMIC under the Code, (ii) avoid or minimize the risk of the imposition of any tax on the 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 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, 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 the REMIC established hereunder or the Certificateholders or cause the 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.

This Agreement is subject to recordation in all appropriate public recording offices or elsewhere, such recordation to be effected by the Depositor 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.

SECTION 9.3 Governing Law.

SECTION 9.4 Intention of Parties.

It is the express intent of the parties hereto that the conveyance of the Trust Fund by the Depositor to the Trustee be, and be construed as, absolute sales thereof to the Trustee.

However, in the event that, notwithstanding the intent of the parties, such assets are held to be the property of the Depositor, or if for any other reason this Agreement is held or deemed to create a security interest in such assets, then (i) this Agreement shall be deemed to be a security agreement within the meaning of the Uniform Commercial Code of the State of New York and (ii) the conveyance provided for in this Agreement shall be deemed to be an assignment and a grant by the Depositor to the Trustee, for the benefit of the Certificateholders, of a security interest in all of the assets that constitute the Trust Fund, whether now owned or hereafter acquired.

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.

If any one or more of the covenants, agreements, provisions or terms of this Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the validity or enforceability of the other provisions of this Agreement or of the Certificates or the rights of the Holders thereof.

SECTION 9.7 Limitation on Rights of Certificateholders.

The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the trust created hereby, nor entitle such Certificateholder’s legal representative or heirs to claim an accounting or to take any action or commence any proceeding in any court for a petition or winding up of the trust created hereby, or otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

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 the occurrence of a default under this Agreement 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 9.8, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

SECTION 9.8 Certificates Nonassessable and Fully Paid.

It is the intention of the Depositor that Certificateholders shall not be personally liable for obligations of the Trust Fund, that the interests in the Trust Fund represented by the Certificates shall be nonassessable for any reason whatsoever, and that the Certificates, upon due authentication thereof by the Trustee pursuant to this Agreement, are and shall be deemed fully paid.

This certifies that _________________ is the registered owner of the Percentage Interest set forth above in certain residual distributions with respect to a Trust Fund consisting of the Underlying Certificates deposited by First Horizon Asset Securities Inc. (the “Depositor”). The Trust Fund was created pursuant to a Pooling Agreement dated as of the Closing Date specified above (the “Agreement”) between the Depositor and The Bank of New York, as trustee (the “Trustee”).

This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

This Certificate has no Class Certificate Balance and it will not accrue any interest.

No transfer of a Class A-R Certificate shall be made unless the Trustee shall have received either (i) a representation [letter] from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Trustee, to the effect that such transferee is not an employee benefit plan or arrangement subject to Section 406 of ERISA or Section 4975 of the Code, nor a person acting on behalf of any such plan, which representation letter shall not be an expense of the Trustee or the Depositor, (ii) if the purchaser is an insurance company, a representation that the purchaser is an insurance company which is purchasing such Certificate 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 Certificate are covered under Sections I and III of PTCE 95-60 or (iii) in the case of any such Certificate presented for registration in the name of an employee benefit plan subject to ERISA or 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, an Opinion of Counsel satisfactory to the Trustee to the effect that the purchase or holding of such Class A-R Certificate will not result in prohibited transactions under Section 406 of ERISA and Section 4975 of the Code and will not subject the Trustee or the Depositor to any obligation in addition to those undertaken in the Agreement, which Opinion of Counsel shall not be an expense of the Trustee or the Depositor. [Such representation shall be deemed to have been made to the Trustee by the Transferee’s acceptance of this Class A-R Certificate and by a beneficial owner’s acceptance of its interest in such Certificate.] Notwithstanding anything else to the contrary herein, any purported transfer of a Class A-R Certificate to or on behalf of an employee benefit plan subject to ERISA or to the Code without the opinion of counsel satisfactory to the Trustee as described above shall be void and of no effect.

Mortgage Pass-Through Certificates

This Certificate is one of a duly authorized issue of Certificates designated as First Horizon Alternative Mortgage Securities Trust 2006-RE1 Mortgage Pass-Through Certificates, of the Series specified on the face hereof (herein collectively called the “Certificates”), and representing a beneficial ownership interest in the Trust Fund created by the Agreement.

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 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 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.

C-1

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 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.

The Certificates are subject to optional termination on any Distribution Date on which the Underlying Certificates are terminated pursuant to terms of the Underlying PSA. 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 of the Underlying Certificates or the disposition of all Trust Fund 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.

Series 2006-RE1

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 A-R Certificate (the “Certificate”) issued pursuant to the Pooling Agreement, (the “Agreement”), relating to the above-referenced Series, by and between First Horizon Asset Securities Inc., as depositor (the “Depositor”), 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 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.)

E-1

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.

E-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__.

“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).

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

E-5

(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 Depositor, 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.
