TRUST AGREEMENT, dated as of November 26, 2007, by and among CWALT, Inc., as depositor (the “Depositor”), Deutsche Bank Securities Inc., as underlying certificate seller (the “Underlying Certificate Seller”), and The Bank of New York, as trustee (the “Trustee”) and in its capacities as Securities Intermediary and as Bank (each as defined below).

WITNESSETH:

WHEREAS, the Depositor, the Underlying Certificate Seller and the Trustee desire to enter into a trust agreement dated as of the date hereof (the “Trust Agreement”); and

WHEREAS, the Underlying Certificate Seller has transferred its interests in and to the Deposited Underlying Certificates (as defined herein) to the Depositor pursuant to a xxxx of sale executed by the Underlying Certificate Seller in favor of the Depositor;

NOW THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

PRELIMINARY STATEMENT

The Depositor is the owner of the Trust Fund that is hereby conveyed to the Trustee in return for the Certificates. For federal income tax purposes, the Trustee shall treat the Trust Fund as consisting of a trust (the “ES Trust”) beneath which are two real estate mortgage investment conduits (or in the alternative, the “Lower Tier REMIC” and the “Master REMIC”) and shall make all elections as necessary for such treatment. The Lower Tier REMIC will hold all the assets of the Trust Fund and will issue several classes of uncertificated Lower Tier REMIC Interests. The Class LTR-A-R Interest is hereby designated as the residual interest in the Lower Tier REMIC and each other Lower Tier REMIC Interest is hereby designated as a regular interest in the Lower Tier REMIC. The Master REMIC will hold all the regular interests in the Lower Tier REMIC and will issue several classes of uncertificated Master REMIC Interests. The Class A-R Interest is hereby designated as the residual interest in the Master REMIC and each other Master REMIC Interest is hereby designated as a regular interest in the Master REMIC. The “latest possible maturity date,” for federal income tax purposes, of all REMIC regular interests created hereby will be the Latest Possible Maturity Date.

The ES Trust shall hold the LTR-A-R Interest, the MR-A-R Interest, all Master REMIC regular interests and shall issue the Certificates. Each Certificate, other than the Class A-R Certificate, will represent ownership of one or more of the Master REMIC regular interests held by the ES Trust. The Class A-R Certificate will represent ownership of the LTR-A-R Interest and the MR-A-R Interest, which are, respectively, the sole Classes of REMIC residual interest in each of the Lower Tier REMIC and the Master REMIC.

For federal income tax purposes the Trustee shall treat the ES Trust as a Grantor Trust and shall treat each Holder of an ES Trust Certificate as the owner of the individual, underlying assets represented by such ES Trust Certificate. In addition, to the fullest extent possible, ownership of an ES Trust Certificate shall be treated as direct ownership of the individual, underlying assets represented by such ES Trust Certificate for federal income tax reporting purposes. The ES Trust will not form part of any REMIC.

The following table sets forth characteristics of the ES Trust Certificates, together with the minimum denominations and integral multiples in excess thereof in which such Classes shall be issuable (except that one Residual Certificate representing the Tax Matters Person Certificate may be issued in a different amount):

ARTICLE II

CONVEYANCE OF THE DEPOSITED UNDERLYING CERTIFICATES;

ORIGINAL ISSUANCE OF CERTIFICATES

Section 2.01 Conveyance of the Deposited Underlying Certificates. The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, convey, sell and assign to the Trustee, on behalf of the Holders of the Certificates, without recourse, all the right, title and interest of the Depositor in and to the Deposited Underlying Certificates with appropriate endorsements and other documentation sufficient under the Underlying Agreement to transfer each such Deposited Underlying Certificate to the Trustee, including all distributions thereon due after November 26, 2007, and all proceeds of the foregoing. Each of the Underlying Certificate Seller and the Depositor severally agrees to transfer to the Trustee (by wire transfer of immediately available funds), any amounts it receives in respect of the Deposited Underlying Certificates due thereon after November 26, 2007 on the same day it receives such funds.

The transfer of the Deposited Underlying Certificates and all other assets constituting the Trust Fund is absolute and is intended by the parties hereto as a sale. The Underlying Certificate Seller hereby confirms that it has caused the beneficial ownership interest in the Deposited Underlying Certificates to be registered with a Depository Participant or an indirect participant in the Depository in the name of the Securities Intermediary for the benefit of the Trustee on behalf of the Certificateholders.

The Securities Intermediary hereby confirms to the Trustee that (i) the Deposited Underlying Certificates have been confirmed by the Depository to have been delivered to the Trustee (on behalf of the Certificateholders), subject to no other interests, and held with the Securities Intermediary, as a Depository Participant, in book-entry form, and (ii) the Securities Intermediary is holding such Deposited Underlying Certificate for the account of the Trustee, on behalf of the Certificateholders. The Trustee hereby acknowledges the receipt by it and the Securities Intermediary of the Deposited Underlying Certificates and the other documents and instruments referenced above, in good faith and without actual notice of any adverse claim, and declares that it holds and will hold the Deposited Underlying Certificates and the other documents and instruments, and that it holds and will continuously hold all other assets in the Trust Fund, in each case, in the State of New York, in trust for the exclusive use and benefit of all present and future Certificateholders. The Trustee shall not permit the Deposited Underlying Certificates or any other asset constituting the Trust Fund to be subjected to any lien, claim or encumbrance arising by, through or under the Trustee or any person claiming by, through or under the Trustee. The Depositor agrees to provide to the Trustee all documents required for the transfer to the Trustee of the Deposited Underlying Certificates.

It is intended that the conveyance of the Deposited Underlying Certificates by the Depositor to the Trustee as provided in this Section be, and be construed as, a sale of the Deposited Underlying Certificates by the Depositor to the Trustee for the benefit of the Certificateholders. It is, further, not intended that such conveyance be deemed a pledge of the Deposited Underlying Certificates by the Depositor to the Trustee to secure a debt or other

obligation of the Depositor. However, in the event that the Deposited Underlying Certificates are held to be the property of the Depositor, or if for any reason this Agreement is held or deemed to create a security interest in the Deposited Underlying Certificates, then it is intended that this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the UCC and the corresponding articles of the Uniform Commercial Code of any other applicable jurisdiction; and the Depositor hereby grants to the Trustee for the benefit of the Certificateholders a security interest in all of the Depositor’s right, title and interest, whether now owned or existing or hereafter acquired or arising, in and to the Trust Fund. The Depositor and the Trustee, at the Depositor’s direction and expense, 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 Deposited Underlying Certificates and other assets constituting the Trust Fund described above, 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.

Section 2.02 Acceptance by Trustee. The Trustee hereby confirms that it has confirmation from BNY, in its capacity as Securities Intermediary for the Trustee that (i) the Deposited Underlying Certificates in book-entry form have been confirmed by the Depository to have been delivered to the Trustee, subject to no other interests, and held in the Securities Intermediary in book-entry form, as a participant in the Depository and (ii) the Securities Intermediary is holding such Deposited Underlying Certificates in book-entry form for the account of the Trustee, as owner of the Deposited Underlying Certificates in its capacity as trustee for the Certificateholders. The Trustee declares that it shall hold ownership interest in the Deposited Underlying Certificates in trust and shall hold all proceeds of any of the foregoing and all other rights, titles or interests of the Trustee in any asset included in the Trust Fund from time to time in trust, upon the terms herein set forth, for the use and benefit of all present and future Certificateholders. The Trustee agrees, for the benefit of Certificateholders, to confirm that the class designation and original principal balance with respect to the Deposited Underlying Certificates conform to the information set forth on Schedule I on the Closing Date.

Section 2.03 Representations and Warranties of the Underlying Certificate Seller. The Underlying Certificate Seller hereby represents and warrants to the Depositor and the Trustee

(ii) the Underlying Certificate Seller has not assigned any interest in the Deposited Underlying Certificates or any distributions thereon, except as contemplated herein;

(iii) the crediting of the Deposited Underlying Certificates to the Securities Account is sufficient to effect the transfer of all right, title and interest in the Deposited

Underlying Certificates to the Trustee pursuant to Section 2.01 hereof free and clean of any lien, pledge, charge or encumbrance of any kind;

(vi) the Deposited Underlying Certificates constitute a “securities entitlement” within the meaning of the UCC;

(v) the Underlying Certificate Seller is not aware of any default or event of default under, or breach of any terms of, the Underlying Agreement or the Deposited Underlying Certificates; and

The payment of the Purchase Price shall be considered a prepayment in full of the Deposited Underlying Certificates and shall be delivered to the Trustee for deposit in the Distribution Account in accordance with the provisions of Section 3.02 hereof. Upon such deposit into such Distribution Account, the repurchased Deposited Underlying Certificates shall be released to the Underlying Certificate Seller, and the Trustee and the Depositor shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be reasonably requested and provided by the Underlying Certificate Seller to vest in the Underlying Certificate Seller, or its designee or assignee, title to the Deposited Underlying Certificates repurchased pursuant hereto. The obligation of the Underlying Certificate Seller to cure such breach of representations and warranties or effect such repurchase of the Deposited Underlying Certificates shall constitute the sole remedy respecting such breach available to Certificateholders or the Trustee on behalf of Certificateholders.

(i) The Underlying Certificate Seller is a corporation organized, validly existing and in good standing under the laws of the State of Delaware with full power and authority to execute, deliver and perform this Agreement.

(a) On each Interest Determination Date so long as any Certificates that have a Pass-Through Rate calculated by reference to LIBOR 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.

(b) If on any Interest Determination Date, LIBOR cannot be determined as provided in paragraph (A) of this Section 4.08, 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 Interest 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 LIBO 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 next Interest Accrual Period will be established by the Trustee on each interest Determination Date as follows:

(i) If on any Interest Determination Date two or more Reference Banks provide such offered quotations, LIBOR for the next applicable 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 Interest 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 Interest 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 Interest 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 Interest Determination Date to leading European banks.

(iii) If on any Interest Determination Date the Trustee is required but is unable to determine the Reserve Interest Rate in the manner provided in paragraph (b) above, LIBOR for the related Classes of Certificates shall be LIBOR as determined on the preceding applicable Interest Determination Date. If on the initial LIBOR Determination Date the Trustee is required but unable to determine LIBOR in the manner provided above, LIBOR for the next Interest Accrual Period will be the Initial LIBOR Rate.

Until all of the LIBOR Certificates are paid in full, the Trustee will at all times retain at least four Reference Banks for the purpose of determining LIBOR with respect to each Interest Determination Date. The Underlying Certificate Seller initially shall designate the Reference Banks. 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 or if the Underlying Certificate Seller should terminate its appointment as Reference Bank, the Trustee 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 to retain at least four Reference Banks which is caused by circumstances beyond its reasonable control.

(c) The Pass-Through Rate for each Class of Certificates, which has a Pass-Through Rate that is calculated by reference to LIBOR, for each Interest Accrual Period shall be determined by the Trustee on each Interest Determination Date so long as the Class Certificate Balance of any such Class is greater than zero, 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 Dow Xxxxx Markets) 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 3.07.

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 3.08 Monthly Statements to Certificateholders. Concurrently with each distribution on a Distribution Date, the Trustee will forward by electronic delivery to each Rating Agency and make available to Certificateholders on the Trustee’s website (xxxx://xxx.xxxxxxxxxxxxxxxxxxxx.xxx) a statement generally setting forth the information contained in Exhibit G hereto. Such statement shall also indicate whether any exchanges of Exchangeable Certificates or Depositable Certificates have occurred since the immediately preceding Distribution Date and, if applicable, the Class designation, Class Certificate Balance or Notional Amount and Pass-Through Rate of any Classes of Certificates that were received by a Certificateholder as a result of such exchange as well as any Net Prepayment Interest Shortfalls and Realized Losses allocated to such Certificates as a result of such exchange.

In addition, the Trustee will make available to Certificateholders on its website copies of the statements received by the Trustee as the holder of the Deposited Underlying Certificates on behalf of the Trust Fund.

Certificateholders and other parties that are unable to use the Trustee’s website are entitled to have paper copies of these statements mailed to them via first class mail by contacting the Trustee and indicating such.

Within a reasonable period of time after the end of each calendar year, the Trustee will prepare and deliver to each person who at any time during the previous calendar year was a Certificateholder of record a statement containing the information required to satisfy any requirements of the Code, the REMIC Provisions and regulations thereunder as from time to time are in force. For purposes of this Section 3.08, the Trustee’s duties are limited to the extent that adequate information is reasonably available to the Trustee as described herein.

Section 3.09 Reports of the Trustee; Distribution Account. Upon written request of a Certificateholder or Certificate Owner and at the expense of such Certificateholder or Certificate Owner, the Trustee shall make available to Certificateholders or Certificate Owners within 15 days after the date of receipt of such request a statement setting forth the status of the Distribution Account as of the close of business on the last day of the calendar month immediately preceding such request, and showing, for the period covered by such statement, the aggregate of deposits into and withdrawals from the Distribution Account.

Section 3.10 Access to Certain Documentation and Information. The Trustee shall provide the related Certificateholders or Certificate Owners with access to a copy of each report, if any, received by it as holder of the Deposited Underlying Certificates under the Underlying Agreement. The Trustee shall also provide the Depositor and the Underlying Certificate Seller with access to any such report and to all written reports, documents and records required to be maintained by the Trustee in respect of its duties hereunder. Such access shall be afforded without charge but only upon reasonable request evidenced by prior written notice received by the Trustee two Business Days prior to the date of such proposed access and during normal business hours at offices designated by the Trustee.

Section 3.11 Annual Statement as to Compliance.

The Trustee shall deliver to the Depositor on or before March 15 of each year, commencing with its 2008 fiscal year, an Officer’s Certificate stating, as to the signer thereof, that (i) a review of the activities of the Trustee during the preceding calendar year (or applicable portion thereof) and of the performance of the Trustee under this Agreement has been made under such officer’s supervision and (ii) to the best of such officer’s knowledge, based on such review, the Trustee has fulfilled all its obligations under this Agreement in all material respects throughout such year (or applicable portion thereof), or, if there has been a failure to fulfill any such obligation in any material respect, specifying each such failure known to such officer and the nature and status thereof.

The Trustee shall cause each Subcontractor, if any, to deliver to the Depositor and the Trustee on or before March 15 of each year, commencing with its 2008 fiscal year, an Officer’s Certificate stating, as to the signer thereof, that (i) a review of the activities of such Subcontractor during the preceding calendar year (or applicable portion thereof) and of the performance of the Subcontractor under the applicable agreement, has been made under such officer’s supervision and (ii) to the best of such officer’s knowledge, based on such review, such Subcontractor has fulfilled all its obligations under the applicable agreement, in all material respects throughout such year (or applicable portion thereof), or, if there has been a failure to fulfill any such obligation in any material respect, specifying each such failure known to such officer and the nature and status thereof.

The Trustee shall forward a copy of each such statement to each Rating Agency.

ARTICLE IV

THE CERTIFICATES

Section 4.01 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 7.01 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) a Notional Amount Certificate, (B) 100% of the Class Certificate Balance of any Class of Certificates or (C) 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 Trust by an authorized officer of the Trustee. 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 4.02 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 4.06 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) [Reserved].

(c) No transfer of an ERISA-Restricted Certificate shall be made unless the Trustee shall have received 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 Residual Certificate such requirement is satisfied only by the Trustee’s receipt of a Representation Letter from the Transferee substantially in the form of Exhibit F to the effect that (x) such transferee is not a Plan or (y) in the case of a Certificate that is an ERISA-Restricted Certificate and that has been the subject of an ERISA-Qualifying Underwriting, a representation that the transferee 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 satisfy the requirements for exemptive relief under Sections I and III of PTCE 95-60 or (ii) in the case of any ERISA-Restricted Certificate presented for registration in the name of a Plan, an Opinion of Counsel satisfactory to the Trustee, which Opinion of Counsel shall not be an expense of either the Trustee or the Trust Fund, addressed to the Trustee to the effect that the purchase and holding of such ERISA-Restricted Certificate will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code and will not subject the Trustee to any obligation in addition to those expressly undertaken in this Agreement or to any liability. For purposes of the preceding sentence, with respect to an ERISA-Restricted Certificate that is not a Residual Certificate, in the event the representation letter or opinion of counsel referred to in the preceding sentence is not so furnished, none of the representations in clause (i), as appropriate, shall be deemed to have been made to the Trustee by the transferee’s (including an initial acquiror’s) acceptance of the ERISA-Restricted Certificates. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Certificate to or on behalf of a Plan 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.

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 or transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 4.02(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 by the Trustee in accordance with the foregoing requirements.

(d) 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) Except in connection with (i) the registration of the Tax Matters Person Certificate in the name of the Trustee or (ii) any registration in the name of, or transfer of a Residual Certificate to, an affiliate of the Depositor or the Underlying Certificate Seller (either directly or through a nominee) in connection with the initial issuance of the Certificates, 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 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 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 and to provide to the Trustee a certificate substantially in the form attached hereto as Exhibit E stating that it has no 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 4.02(d) 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 4.02(d), 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 4.02(c) and this Section 4.02(d) 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 and Transferor Certificate. 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 4.02(d) 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 Underlying Certificate Seller or the Depositor, to the effect that the elimination of such restrictions will not cause each REMIC 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.

(e) The preparation and delivery of all certificates and opinions referred to above in this Section 4.02(e) in connection with transfer shall be at the expense of the parties to such transfers.

(f) 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 or (y) after the occurrence of an Underlying Event of Default, the Certificate Owners representing at least 51% of the Certificate Balance of the Book-Entry Certificates together advise the Trustee and the Depository through the Depository Participants in writing that continuation of the 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 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 Depositor 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 4.03 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 Depositor 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 4.03, 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 4.03 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 4.04 Persons Deemed Owners.

The Depositor, the Trustee and any agent of the Depositor 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 Depositor, the Trustee nor any agent of the Depositor or the Trustee shall be affected by any notice to the contrary.

Section 4.05 Access to List of Certificateholders’ Names and Addresses.

If three or more Certificateholders and/or Certificate Owners (a) request such information in writing from the Trustee, (b) state that such Certificateholders and/or Certificate Owners desire to communicate with other Certificateholders and/or Certificate Owners with respect to their rights under this Agreement or under the Certificates, and (c) provide a copy of the communication which such Certificateholders and/or Certificate Owners propose to transmit, or if the Depositor 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 or such Certificateholders and/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 and/or Certificate Owner, by receiving and holding a Certificate or beneficial interest therein, 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 4.06 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.

Section 4.07 Depositable and Exchangeable Certificates.

(a) On the Closing Date, there is hereby established a separate trust (the “ES Trust”), which shall be a Grantor Trust for federal income tax purposes. The ES Trust shall be maintained by the Trustee in its name, for the benefit of the Holders of the Certificates. The assets of the ES Trust shall consist of the LTR-A-R Interest and the uncertificated Master REMIC Interests, which have been placed in the ES Trust through the efforts of the Underwriter. The LTR-A-R Interest and the uncertificated Master REMIC Interests in the ES Trust shall be held by the Trustee. On the Closing Date, the ES Trust shall issue the several Classes of Certificates. Each Class of Exchangeable Certificates shall be issued on the Closing Date with a Class Certificate Balance of zero. Upon the sale of the Certificates on the Closing Date, the Exchangeable Certificates shall be placed with the Trustee through the efforts of the Underwriter to be held to facilitate the exchange of Depositable and Exchangeable Certificates on and after the Closing Date. Among the Depositable and Exchangeable Certificates, the beneficial interest of the uncertificated Master REMIC Interests shall be represented by the related Depositable Certificates until such Depositable Certificates have been exchanged for Exchangeable

Certificates, at which time, such Exchangeable Certificates shall represent those uncertificated Master REMIC Interests.

The Trustee, as trustee of the ES Trust, shall establish and maintain, on behalf of the Holders of the Exchangeable Certificates, the Exchangeable Certificates Distribution Account. All funds on deposit in the Exchangeable Certificates Distribution Account shall be held separate and apart from, and shall not be commingled with, any other moneys, including without limitation, other moneys held by the Trustee pursuant to this Agreement.

On each Distribution Date, the Trustee, as holder of any surrendered Depositable Certificates, shall deposit in the Exchangeable Certificates Distribution Account any amounts distributable to the surrendered Depositable Certificates pursuant to Section 3.04. For the avoidance of doubt, if on any Distribution Date no Classes of Depositable Certificates have been surrendered or if all Classes of Exchangeable Certificates have been exchanged for Depositable Certificates according to Section 4.07(e), then no amounts will be deposited in the Exchangeable Certificates Deposit Account on such Distribution Date.

On each Distribution Date, the Trustee shall make withdrawals from the Exchangeable Certificates Distribution Account to make distributions to the Classes of Exchangeable Certificates then entitled to distributions pursuant to Section 4.07(b).

Funds in the Exchangeable Certificates Distribution Account shall remain uninvested.

(b) On each Distribution Date, the Trustee shall withdraw funds on deposit in the Exchangeable Certificates Distribution Account on deposit therein from distributions to the surrendered Depositable Certificates for such Distribution Date and distribute such amount to the Holders of each related Class of Exchangeable Certificates. Amounts related to interest distributed to the surrendered Depositable Certificates shall be distributed as interest to the related Class or Classes of Exchangeable Certificates pursuant to Section 3.04(a)(2). All distributions of principal to the Exchangeable Certificates shall be made pro rata among the Classes of Exchangeable Certificates within each Combination Group unless specifically provided for otherwise in Schedule III. All distributions that are made with respect to a particular Class of Exchangeable Certificates shall be made pro rata among all Certificates of such Class in proportion to their respective Class Certificate Balances or Notional Amounts.

In addition, the Trustee may from time to time make withdrawals from the Exchangeable Certificates Distribution Account for the following purposes:

(i) to withdraw any amount deposited in the Exchangeable Certificates Distribution Account and not required to be deposited therein; and

(ii) to clear and terminate the Exchangeable Certificates Distribution Account upon the termination of this Agreement.

(c) On each Distribution Date on which a Class of Exchangeable Certificates shall be entitled to receive distributions pursuant to Section 4.07(b), such Class shall be allocated a proportionate share of the Underlying Net Prepayment Interest Shortfalls, the interest portion of any Underlying Debt Service Reductions and Underlying Relief Act Reductions allocable to the Classes of Depositable Certificates in the related Combination Group.

(d) On each Distribution Date on which a Class of Exchangeable Certificates shall be entitled to receive distributions pursuant to Section 4.07(b), such Class shall be allocated a proportionate share of the Realized Losses allocable to the Classes of Depositable Certificates in the related Combination Group.

(e) Upon the presentation and surrender of the Depositable Certificates, the Holder thereof transfers, assigns, sets over and otherwise conveys to the Trustee of the ES Trust, all of such Holder’s right, title and interest in and to such Depositable Certificates, including all payments of interest thereon received after the month of the exchange. The Trustee on behalf of the ES Trust shall furnish written acknowledgement to the Holder of such surrendered Certificate of the transfer and assignment to it of such Depositable Certificates.

At the request of the Holder of a Class or Classes of Depositable Certificates, and upon the surrender of such Depositable Certificates, the Trustee shall deliver such Exchangeable Certificates as set forth in such Combination Group in the respective Denominations determined based on the proportion that the initial Class Certificate Balance or initial Notional Amounts of such Exchangeable Certificates bear to the initial Class Certificate Balances of the Depositable Certificates, as set forth in Schedule III, which shall represent in the aggregate, the entire beneficial ownership of the Master REMIC Interests related to such surrendered Certificates. In addition, at the request of the Holder of a Class or Classes of Exchangeable Certificates, and upon the surrender of such Exchangeable Certificates, the Trustee shall exchange such Exchangeable Certificates for another Class or Classes of Exchangeable Certificates or the related surrendered Depositable Certificates, as set forth in Schedule III. There shall be no limitation on the number of exchanges authorized pursuant to this Section 4.07.

Holders may exchange their Certificates according to this Section 4.07(e) by (i) providing notice to the Trustee no later than three (3) Business Days prior to the date on which the Holder wishes to make such exchange (the “Exchange Date”), which Exchange Date is subject to the Trustee’s approval and shall not be the first or last Business Day of the month, (ii) remitting the Exchange Fee, as determined in the next paragraph, to the Trustee and (iii) remitting the beneficial interest in the Depositable Certificates or the Exchangeable Certificates, as applicable, to the Trustee. Any such notice to the Trustee (A) may be provided to the Trustee by email at xxxxxxx@xxxxxxxx.xxx or by telephone at (000) 000-0000, (B) must include (i) the Certificateholder’s letterhead, (ii) a medallion stamp guarantee or be signed by an authorized signatory and be presented with an incumbency certificate and (iii) set forth the following information: (a) the CUSIP number of both the Certificates to be exchanged and the Certificates to be received, (b) the outstanding Class Certificate Balance or Notional Amount and the initial Class Certificate Balance or initial Notional Amount of the Certificates to be exchanged, (c) the Certificateholder’s DTC participant number and (d) the proposed Exchange Date, and (C) is irrevocable beginning on the second Business Day prior to the Exchange Date. Such exchange will be completed by the Trustee upon the receipt by the Trustee of the Exchange Fee and the beneficial interest in the Depositable Certificates or the Exchangeable Certificates, as applicable.

The preparation of all Certificates referred to in this Section 4.07(e) in connection with an exchange shall be at the expense of the parties to such exchanges. For each exchange, the Certificateholder must pay the Trustee a fee (the “Exchange Fee”) equal to 1/32 of 1% of the current Class Certificate Balance of the Certificates to be Exchanged but in no event shall the fee be less than $2,000 or greater than $25,000.

ARTICLE V

CONCERNING THE TRUSTEE

Section 5.01 Duties of Trustee.

The Trustee shall undertake to perform such duties and only such duties as are specifically set forth in this Agreement.

The Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice of resignation to the Depositor, the Underlying Certificate Seller and each Rating Agency not less than 60 days before the date specified in such notice when, subject to Section 5.09, such resignation is to take effect, and acceptance by a successor trustee in accordance with Section 5.09 meeting the qualifications set forth in Section 5.07. 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.

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 of which shall be delivered 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 Depositor, one complete set to the Trustee so removed and one complete set to the successor so appointed, together with a written description of the basis of such removal. Notice of any removal of the Trustee shall be given to each Rating Agency and the Underlying Certificate Seller by the successor trustee.

Section 5.09 Successor Trustee.

Any successor trustee appointed as provided in Section 5.08 hereof shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee and the Depositor 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 5.09 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 5.07 hereof, its appointment shall not adversely affect the then current rating of the Certificates and such successor trustee has provided to 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 replacement Trustee.

Upon acceptance of appointment by a successor trustee as provided in this Section 5.09, 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 5.10 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 5.07 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.

As a condition to the effectiveness of any merger or consolidation, at least 15 calendar days prior to the effective date of any merger or consolidation of the Trustee, 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 a replacement Trustee.

Section 5.11 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 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 5.11, 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 5.07 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 5.09.

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 5.11, 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 Depositor 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; and

(iii) The Trustee may at any time accept the resignation of or remove any 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 V. 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.

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 3.04. hereof, on the final Distribution Date 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

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 conform this Agreement to the Prospectus and Prospectus Supplement provided to investors in connection with the initial offering of the Certificates; (iv) to add to the duties of the Depositor; (v) to modify, alter, amend, add, or to rescind any of the terms or provisions contained in this Agreement to comply with any rules or regulations promulgated by the Securities and Exchange Commission from time to time; (vi) to add any other provisions with respect to matters or questions arising hereunder; or (vii) 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 (vi) or (vii) above shall not, as evidenced by an Opinion of Counsel (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. Notwithstanding the foregoing, no amendment that significantly changes the permitted activities of the Trust created by this Agreement may be made without the consent of a Majority in Interest of each Class of Certificates affected by such amendment. Each party to this Agreement hereby agrees that it will cooperate with each other party in amending this Agreement pursuant to clause (v) above. 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 any REMIC as a REMIC under the Code, (ii) avoid or minimize the risk of the imposition of any tax on any REMIC 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 Underlying Certificate Seller (which will not be unreasonably withheld) and 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 2/3% 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.

Any amendment made pursuant to either of the preceding two paragraphs that materially and adversely affects the rights of the Underlying Certificate Seller shall not be made without the prior written consent of the Underlying Certificate Seller.

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 or the Certificateholders or cause any REMIC 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 8.01.

Section 8.02 Action Under and Conflicts With the Underlying Agreement. Subject to the terms hereof, in the event that there shall be any matters arising under the Underlying Agreement which require the vote or direction of the holders of the Deposited Underlying Certificates, the Trustee, as holder of the Deposited Underlying Certificates, shall vote the Deposited Underlying Certificates in accordance with instructions received from Holders of a Majority in Interest of the related Class of Regular Certificates. In the absence of any such instructions, the Trustee shall not vote; provided, however, that, notwithstanding the absence of such instructions, in the event a required distribution pursuant to the Underlying Agreement shall not have been made, the Trustee shall, subject to the provisions of Article V hereof, pursue such remedies as may be available to it as holder of such Deposited Underlying Certificates in accordance with the terms of the Underlying Agreement.

Section 8.03 Recordation of Agreement. This Agreement (or an abstract hereof, if acceptable by the applicable recording office) is subject to recordation in all appropriate public offices for real property records in all the counties or other comparable jurisdiction in which any or all of the properties subject to the underlying mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Depositor at its expense but only upon direction by the Trustee accompanied by an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

Section 8.05 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 there shall have been a failure to pay amounts due under this Agreement to the Certificateholders and 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 8.05, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

(b) In the event that the Trustee or Reporting Subcontractor is terminated or resigns during the term of this Agreement, such Person shall provide documents and information required by this Section 9.07 with respect to the period of time it was subject to this Agreement or provided services with respect to the Trust Fund, the Certificates or the Deposited Underlying Certificates.

(c) An assessment of compliance provided by a Subcontractor pursuant to Section 9.07(a)(3) need not address any elements of the Servicing Criteria other than those specified by the Trustee, as applicable, pursuant to Section 9.07(a)(1).

Section 9.08

Use of Subcontractors.

It shall not be necessary for the Trustee to seek the consent of the Depositor or any other party hereto to the utilization of any Subcontractor. The Trustee shall promptly upon request provide to the Depositor (or any designee of the Depositor, such as the administrator) a written description (in form and substance satisfactory to the Depositor) of the role and function of each Subcontractor utilized by such Person, 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 identified pursuant to clause (ii) of this paragraph.

As a condition to the utilization of any Subcontractor determined to be a Reporting Subcontractor, the Trustee shall cause any such Subcontractor used by the Trustee for the benefit of the Depositor to comply with the provisions of Sections 9.07 and 9.09 of this Agreement to the same extent as if such Subcontractor were the Trustee (except with respect to preparing and filing any Exchange Act Reports or as the Certifying Person). The Trustee shall be responsible for obtaining from each Subcontractor and delivering to the Depositor any assessment of compliance and attestation required to be delivered by such Subcontractor under Section 9.05 and Section 9.07, in each case as and when required to be delivered.

Section 9.09

Amendments.

In the event the parties to this Agreement desire to further clarify or amend any provision of this Article IX, this Agreement shall be amended to reflect the new agreement between the parties covering matters in this Article IX pursuant to Section 8.01, which amendment shall not require any Opinion of Counsel or Rating Agency confirmations or the consent of any Certificateholder.

Resecuritization 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 Certificates are limited in right of payment to certain distributions in respect of the Deposited Underlying Certificates, all as more specifically set forth in 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 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 the first Distribution Date is December __, 2007 and to each other 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 Underlying Certificate Seller 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.

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 obligations and responsibilities created by the Agreement will terminate upon the later of the maturity or other liquidation of the Deposited Underlying Certificates 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.

CWALT, Inc.

Resecuritization Mortgage Certificates, Series 2007-26R

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 Trust Agreement, (the “Agreement”) dated as of November 26, 2007 among CWALT, Inc., as depositor (the “Depositor”), Deutsche Bank Securities Inc., as underlying certificate seller, 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 will endeavor to remain a Permitted Transferee for so long as it retains its Ownership Interest in the Certificate. The Transferee is acquiring its Ownership Interest in the Certificate for its own account.

3 The Transferee has been advised of, and understands that (i) a tax will 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 will 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

F-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 4.02(d) 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 4.02(d) 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 J 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 a U.S. Person as defined in Code section 7701(a)(30) and, unless the Transferor (or any subsequent transferor) expressly waives such requirement, will not cause income from the Certificate to be attributable to a foreign permanent establishment or fixed base (within the meaning of an applicable income tax treaty) of the Transferee or another U.S. taxpayer.

10 The Transferee is aware that the Class A-R Certificates may be “noneconomic residual interests” within the meaning of Treasury Regulation Section 1.860E-1(c) 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. In addition, as the Holder of a noneconomic residual interest, the Transferee may incur tax liabilities in excess of any cash flows generated by the interest and the Transferee hereby represents that it intends to pay taxes associated with holding the residual interest as they become due.

11 The Transferee has provided financial statements or other financial information requested by the Transferor in connection with the transfer of the Certificate to permit the Transferor to assess the financial capability of the Transferee to pay such taxes. The Transferee

F-2

historically has paid its debts as they have come due and intends to pay its debts as they come due in the future.

12 Either (i) the Transferee is not an employee benefit plan subject to Section 406 of ERISA or Section 4975 of the Code, nor a person acting on behalf of any such plan or using the assets of such plan to effect such acquisition, or, (ii) if the Class A-R Certificate has been subject to an ERISA-Qualifying underwriting, the source of funds for the purchase of such Class A-R Certificate is an “insurance company general account” within the meaning of Prohibited Transaction Class Exemption 95-60 (PTCE 95-60”), 60 Fed. Reg. 35925 (July 12, 1995), and the terms and conditions of Sections I and III of PTCE 95-60 are applicable to the acquisition and holding of such Class A-R Certificate.

13 Unless the Transferor (or any subsequent transferor) expressly waives such requirement, the Transferee (and any subsequent transferee) certifies (or will certify), respectively, that the transfer satisfies either the “Asset Test” imposed by Treasury Regulation §1.860E-1(c)(5) or the “Formula Test” imposed by Treasury Regulation § 1.860E-1(c)(7).

WAIVER OF REQUIREMENT THAT TRANSFEREE CERTIFIES TRANSFER OF CERTIFICATE SATISFIES CERTAIN REGULATORY “SAFE HARBORS”

The Transferor hereby waives the requirement that the Transferee certify that the transfer of the Certificate satisfies either the “Asset Test” imposed by Treasury Regulation § 1.860E-1(c)(5) or the “Formula Test” imposed by Treasury Regulation § 1.860E-1(c)(7).

Certain Definitions

“Asset Test”: A transfer satisfies the Asset Test if: (i) At the time of the transfer, and at the close of each of the transferee's two fiscal years preceding the transferee's fiscal year of transfer, the transferee's gross assets for financial reporting purposes exceed $100 million and its net assets for financial reporting purposes exceed $10 million. The gross assets and net assets of a transferee do not include any obligation of any “related person” or any other asset if a principal purpose for holding or acquiring the other asset is to permit the transferee to satisfy such monetary conditions; (ii) The transferee must be an “eligible corporation” and must agree in writing that any subsequent transfer of the interest will be to another eligible corporation in a transaction that satisfies paragraphs 9 through 11 of this Transfer Affidavit and the Asset Test. A transfer fails to meet the Asset Test if the transferor knows, or has reason to know, that the transferee will not honor the restrictions on subsequent transfers of the Certificate; and (iii) A reasonable person would not conclude, based on the facts and circumstances known to the transferor on or before the date of the transfer, that the taxes associated with the Certificate will not be paid. The consideration given to the transferee to acquire the Certificate is only one factor to be considered, but the transferor will be deemed to know that the transferee cannot or will not pay if the amount of consideration is so low compared to the liabilities assumed that a reasonable person would conclude that the taxes associated with holding the Certificate will not be paid. For purposes of applying the Asset Test, (i) an “eligible corporation” means any domestic C corporation (as defined in section 1361(a)(2) of the Code) other than (A) a corporation which is exempt from, or is not subject to, tax under section 11 of the Code, (B) an entity described in section 851(a) or 856(a) of the Code, (C) A REMIC, or (D) an organization to which part I of subchapter T of chapter 1 of subtitle A of the Code applies; (ii) a “related person” is any person that (A) bears a relationship to the transferee enumerated in section 267(b) or 707(b)(1) of the Code, using “20 percent” instead of “50 percent” where it appears under the provisions, or (B) is under common control (within the meaning of section 52(a) and (b)) with the transferee.

“Formula Test”: A transfer satisfies the formula test if the present value of the anticipated tax liabilities associated with holding the Certificate does not exceed the sum of (i) the present value of any consideration given to the transferee to acquire the Certificate; (ii) the present value of the expected future distributions on the Certificate; and (iii) the present value of the anticipated tax savings associated with holding the Certificate as the issuing REMIC generates losses. For purposes of applying the Formula Test: (i) The transferee is assumed to pay tax at a rate equal to the highest rate of tax specified in section 11(b)(1) of the Code. If the transferee has been subject to the alternative minimum tax under section 55 of the Code in the preceding two years and will compute its taxable income in the current taxable year using the alternative minimum tax rate, then the tax rate specified in section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in section 11(b)(1) of the Code; (ii) The transfer must satisfy paragraph 9 of the Transfer Affidavit; and (iii) Present values are computed using a

F-6

discount rate equal to the Federal short-term rate prescribed by section 1274(d) of the Code for the month of the transfer and the compounding period used by the taxpayer.

“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) that 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)(1) of the Code) with respect to any Class A-R 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 citizen or resident of the United States, a corporation, partnership, or other entity (treated as a corporation or a partnership for federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, or 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 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 authority to control all substantial decisions of the trustor unless such Person has furnished the transferor and the Trustee with a duly completed Internal Revenue Service Form W-8ECI, and (vii) any other Person so designated by the Trustee based upon an Opinion of Counsel that the Transfer of an Ownership Interest in a Class A-R Certificate to such Person may cause any REMIC formed under the Agreement to fail to qualify as a REMIC at any time that any Certificates are Outstanding. 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, limited liability company, partnership, joint venture, bank, joint stock company, trust (including any beneficiary thereof), unincorporated organization or government or any agency or political subdivision thereof.

“Transfer”: Any direct or indirect transfer or sale of any Ownership Interest in a Certificate, including the acquisition of a Certificate by the Depositor.

“Transferee”: Any Person who is acquiring by Transfer any Ownership Interest in a Certificate.

Section 4.02(d) of the Agreement

(1) 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.

(2) Except in connection with (i) the registration of the Tax Matters Person Certificate in the name of the Trustee or (ii) any registration in the name of, or transfer of a Class A-R Certificate to, an affiliate of the Depositor (either directly or through a nominee) in connection with the initial issuance of the Certificates, 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 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 F.

(3) 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.

(4) Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 4.02(d) 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 4.02(d), 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

F-8

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 4.02(c) and this Section 4.02(d) 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 and Transferor Certificate. 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.

(5) 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 4.02(d) 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 Underlying Certificate Seller or the Depositor, to the effect that the elimination of such restrictions will not cause any constituent REMIC of any REMIC formed 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.
