WITNESSETH THAT

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 is a two real estate mortgage investment conduits (or in the alternative, the “”Strip (STR) REMIC” and the “Master REMIC”) and shall make all elections as necessary for such treatment. The Strip REMIC will hold all the assets of the Trust Fund and will issue several classes of uncertificated Strip REMIC Interests. The Class STR-A-R Interest is hereby designated as the residual interest in the Strip REMIC and each other Strip REMIC Interest is hereby designated as a regular interest in the Strip REMIC. The Master REMIC will hold all the interests in the Strip REMIC (except the STR-A-R Interest) and will issue several classes of uncertificated Master REMIC Interests. The Class MR-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 STR-A-R Interest, the MR-A-R Interest and 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 STR-A-R Interest and the MR-A-R Interest which are the sole Classes of REMIC residual interest in the Strip REMIC and Master REMIC, respectively.

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.

II-2

from the mortgagee to the Trustee with evidence of recording thereon (or in a form suitable for recordation).

In addition, in connection with the assignment of any MERS Mortgage Loan, each Seller agrees that it will cause, at the Trustee’s expense, the MERS® System to indicate that the Mortgage Loans sold by such Seller to the Depositor have been assigned by that Seller to the Trustee in accordance with this Agreement (and any Supplemental Transfer Agreement, as applicable) for the benefit of the Certificateholders by including (or deleting, in the case of Mortgage Loans which are repurchased in accordance with this Agreement) in such computer files the information required by the MERS® System to identify the series of the Certificates issued in connection with such Mortgage Loans. Each Seller further agrees that it will not, and will not permit the Master Servicer to, and the Master Servicer agrees that it will not, alter the information referenced in this paragraph with respect to any Mortgage Loan sold by such Seller to the Depositor during the term of this Agreement unless and until such Mortgage Loan is repurchased in accordance with the terms of this Agreement.

In the event that in connection with any Mortgage Loan that is not a MERS Mortgage Loan the Depositor cannot deliver (a) the original recorded Mortgage, or a copy of such mortgage, with recording information, (b) all interim recorded assignments, or a copy of such assignments, with recording information or (c) the lender’s title policy or a copy of the lender’s title policy (together with all riders thereto) satisfying the requirements of clause (ii), (iii) or (v) above, respectively, concurrently with the execution and delivery of this Agreement because such document or documents have not been returned from the applicable public recording office in the case of clause (ii) or (iii) above, or because the title policy has not been delivered to either the Master Servicer or the Depositor by the applicable title insurer in the case of clause (v) above, the Depositor shall promptly deliver to the Trustee, in the case of clause (ii) or (iii) above, such original Mortgage or a copy of such mortgage, with recording information, or such interim assignment or a copy of such assignment, with recording information, as the case may be, with evidence of recording indicated thereon upon receipt thereof from the public recording office, or a copy thereof, certified, if appropriate, by the relevant recording office, but in no event shall any such delivery of the original Mortgage and each such interim assignment or a copy thereof, certified, if appropriate, by the relevant recording office, be made later than one year following the Closing Date, or, in the case of clause (v) above, no later than 120 days following the Closing Date; provided, however, in the event the Depositor is unable to deliver by such date each Mortgage and each such interim assignment by reason of the fact that any such documents have not been returned by the appropriate recording office, or, in the case of each such interim assignment, because the related Mortgage has not been returned by the appropriate recording office, the Depositor shall deliver such documents to the Trustee as promptly as possible upon receipt thereof and, in any event, within 720 days following the Closing Date. The Depositor shall forward or cause to be forwarded to the Trustee (a) from time to time additional original documents evidencing an assumption or modification of a Mortgage Loan and (b) any other documents required to be delivered by the Depositor or the Master Servicer to the Trustee. In the event that the original Mortgage is not delivered and in connection with the payment in full of the related Mortgage Loan and the public recording office requires the presentation of a “lost instruments affidavit and indemnity” or any equivalent document, because only a copy of the Mortgage can be delivered with the instrument of satisfaction or reconveyance, the Master Servicer shall execute and deliver or cause to be executed and delivered such a document to the public recording office. In the case where a public recording office retains the original recorded Mortgage or in the case where a Mortgage is lost after recordation in a public recording office, Countrywide shall deliver to the Trustee a copy of such Mortgage certified by such public recording office to be a true and complete copy of the original recorded Mortgage.

As promptly as practicable subsequent to such transfer and assignment, and in any event, within one-hundred and twenty (120) days after such transfer and assignment, the Trustee shall (A) as the

II-3

assignee thereof, affix the following language to each assignment of Mortgage: “CWALT Series 2007-23CB, The Bank of New York, as trustee”, (B) cause such assignment to be in proper form for recording in the appropriate public office for real property records and (C) cause to be delivered for recording in the appropriate public office for real property records the assignments of the Mortgages to the Trustee, except that, (i) with respect to any assignments of Mortgage as to which the Trustee has not received the information required to prepare such assignment in recordable form, the Trustee’s obligation to do so and to deliver the same for such recording shall be as soon as practicable after receipt of such information and in any event within thirty (30) days after receipt thereof and (ii) the Trustee need not cause to be recorded any assignment which relates to a Mortgage Loan, the Mortgaged Property and Mortgage File relating to which are located in any jurisdiction (including Puerto Rico) under the laws of which the recordation of such assignment is not necessary to protect the Trustee’s and the Certificateholders’ interest in the related Mortgage Loan as evidenced by an opinion of counsel delivered by Countrywide to the Trustee within 90 days of the Closing Date (which opinion may be in the form of a “survey” opinion and is not required to be delivered by counsel admitted to practice law in the jurisdiction as to which such legal opinion applies).

In the case of Mortgage Loans that have been prepaid in full as of the Closing Date, the Depositor, in lieu of delivering the above documents to the Trustee, will deposit in the Certificate Account the portion of such payment that is required to be deposited in the Certificate Account pursuant to Section 3.05 hereof.

Notwithstanding anything to the contrary in this Agreement, within thirty (30) days after the Closing Date with respect to the Initial Mortgage Loans, Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall either (i) deliver to the Depositor, or at the Depositor’s direction, to the Trustee or other designee of the Depositor the Mortgage File as required pursuant to this Section 2.01 for each Delay Delivery Mortgage Loan or (ii) either (A) substitute a Substitute Mortgage Loan for the Delay Delivery Mortgage Loan or (B) repurchase the Delay Delivery Mortgage Loan, which substitution or repurchase shall be accomplished in the manner and subject to the conditions set forth in Section 2.03 (treating each Delay Delivery Mortgage Loan as a Deleted Mortgage Loan for purposes of such Section 2.03); provided, however, that if Countrywide fails to deliver a Mortgage File for any Delay Delivery Mortgage Loan within the thirty (30) day period provided in the prior sentence, Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall use its best reasonable efforts to effect a substitution, rather than a repurchase of, such Deleted Mortgage Loan and provided further that the cure period provided for in Section 2.02 or in Section 2.03 shall not apply to the initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan, but rather Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall have five (5) Business Days to cure such failure to deliver. At the end of such thirty (30) day period the Trustee shall send a Delay Delivery Certification for the Delay Delivery Mortgage Loans delivered during such thirty (30) day period in accordance with the provisions of Section 2.02.

Notwithstanding anything to the contrary in this Agreement, within twenty (20) days after a Supplemental Transfer Date with respect to all of the Supplemental Mortgage Loans sold to the Depositor on such Supplemental Transfer Date, Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall either (i) deliver to the Depositor, or at the Depositor’s direction, to the Trustee or other designee of the Depositor the Mortgage File as required pursuant to this Section 2.01 for each Delay Delivery Mortgage Loan or (ii) (A) substitute a Substitute Mortgage Loan for the Delay Delivery Mortgage Loan or (B) repurchase the Delay Delivery Mortgage Loan, which substitution or repurchase shall be accomplished in the manner and subject to the conditions set forth in Section 2.03 (treating each Delay Delivery Mortgage Loan as a Deleted Mortgage Loan for purposes of such Section 2.03); provided, however, that if Countrywide fails to deliver a Mortgage File for any Delay Delivery Mortgage Loan within the twenty (20) day period provided in the prior sentence, Countrywide

II-4

(on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall use its best reasonable efforts to effect a substitution, rather than a repurchase of, such Deleted Mortgage Loan and provided further that the cure period provided for in Section 2.02 or in Section 2.03 shall not apply to the initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan, but rather Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall have five (5) Business Days to cure such failure to deliver. At the end of such twenty (20) day period the Trustee shall send a Delay Delivery Certification for the Delay Delivery Mortgage Loans delivered during such twenty (20) day period in accordance with the provisions of Section 2.02.

(d) Subject to the execution and delivery of the related Supplemental Transfer Agreement as provided in Section 2.01(e) hereof and the terms and conditions of this Agreement, each Seller sells, transfers, assigns, sets over and otherwise conveys to the Depositor, without recourse, on each Supplemental Transfer Date, with respect to each Supplemental Mortgage Loan sold by such Seller to the Depositor, all the right, title and interest of that Seller in and to the Supplemental Mortgage Loans sold by it identified in such Supplemental Transfer Agreement, including all interest and principal received and receivable by such Seller on or with respect to the related Supplemental Mortgage Loans on and after the related Supplemental Cut-off Date (to the extent not applied in computing the Cut-off Date Principal Balance thereof) or deposited into the Certificate Account by the related Seller, other than principal and interest due on such Supplemental Mortgage Loans prior to the related Supplemental Cut-off Date.

Immediately upon the conveyance of the Supplemental Mortgage Loans referred to in the preceding paragraph, the Depositor sells, transfers, assigns, sets over and otherwise conveys to the Trustee for benefit of the Certificateholders, without recourse, all right title and interest in all of the Supplemental Mortgage Loans.

Each Seller has entered into this Agreement in consideration for the purchase of the Mortgage Loans sold by such Seller to the Depositor and has agreed to take the actions specified herein. The Depositor, concurrently with the execution and delivery of this Agreement, hereby sells, transfers, assigns and otherwise conveys to the Trustee for the use and benefit of the Certificateholders, without recourse, all right title and interest in the portion of the Trust Fund not otherwise conveyed to the Trust Fund pursuant to Sections 2.01(a) or (b).

(e) Upon five (5) Business Days written notice to the Trustee, the Depositor, the Master Servicer (if the Master Servicer is not a Seller) and the Rating Agencies, on any other Business Day during the Funding Period designated by Countrywide, Park Granada, Park Monaco and Park Sienna, if applicable, the Depositor and the Trustee shall complete, execute and deliver a Supplemental Transfer Agreement so long as no Rating Agency has provided notice that the execution and delivery of such Supplemental Transfer Agreement will result in a reduction or withdrawal of any ratings assigned to the Certificates. After the execution and delivery of such Supplemental Transfer Agreement, on the Supplemental Transfer Date, the Trustee shall set aside in the Pre-Funding Account an amount equal to the Aggregate Supplemental Purchase Amount.

The transfer of Supplemental Mortgage Loans and the other property and rights relating to them on a Supplemental Transfer Date is subject to the satisfaction of each of the following conditions:

(i) each Supplemental Mortgage Loan conveyed on such Supplemental Transfer Date satisfies the representations and warranties applicable to it under this Agreement; provided, however, that with respect to a breach of a representation and warranty with respect to a Supplemental Mortgage Loan, the obligation under Section 2.03(c) of this Agreement of Countrywide, Park Granada, Park Monaco and Park Sienna, if applicable, to cure, repurchase or

II-5

replace such Supplemental Mortgage Loan shall constitute the sole remedy against such Seller respecting such breach available to Certificateholders, the Depositor or the Trustee;

(ii) the Trustee, the Underwriter and the Rating Agencies are provided with an Opinion of Counsel or Opinions of Counsel with respect to the tax treatment of the Trust Fund, to be delivered as provided pursuant to Section 2.01(f);

(vi) no Supplemental Mortgage Loan conveyed on such Supplemental Transfer date was 30 or more days delinquent;

(vii) the aggregate of the PO Percentages of the Stated Principal Balance of all Supplemental Mortgage Loans shall not exceed the PO Sublimit;

(viii) following the conveyance of the Supplemental Mortgage Loans on such Supplemental Transfer Date to the Trust Fund, the characteristics of the Mortgage Loans will comply with the Pool Characteristics (including the permitted variances listed therein); provided, that for the purpose of making these calculations, the characteristics for any Initial Mortgage Loan made will be taken as of the Initial Cut-off Date and the characteristics for any Supplemental Mortgage Loan will be taken as of the related Supplemental Cut-off Date;

(ix) none of the Sellers or the Depositor shall be insolvent or shall be rendered insolvent as a result of such transfer; and

(x) the Depositor shall have delivered to the Trustee an Officer’s Certificate confirming the satisfaction of each of these conditions precedent.

The Trustee shall not be required to investigate or otherwise verify compliance with these conditions, except for its own receipt of documents specified above, and shall be entitled to rely on the required Officer’s Certificate.

(f) Within seven Business Days after each Supplemental Transfer Date, upon (1) delivery to the Trustee by the Depositor or Countrywide of the Opinions of Counsel referred to in Sections 2.01(e)(ii) and (iii), (2) delivery to the Trustee by Countrywide of a revised Mortgage Loan Schedule reflecting the Supplemental Mortgage Loans conveyed on such Supplemental Transfer Date and (3) delivery to the Trustee by the Depositor of an Officer’s Certificate confirming the satisfaction of each of the conditions precedent set forth in this Section 2.01(f), the Trustee shall pay to each Seller the portion of the Aggregate Supplemental Transfer Amount used to purchase Supplemental Mortgage Loans from such Seller from those funds that were set aside in the Pre-Funding Account pursuant to Section 2.01(e).

II-6

The positive difference, if any, between the Aggregate Supplemental Transfer Amount and the Aggregate Supplemental Purchase Amount shall be reinvested by the Trustee in the Pre-Funding Account.

(g) The Trustee shall not be required to investigate or otherwise verify compliance with the conditions set forth in the preceding paragraph, except for its own receipt of documents specified above, and shall be entitled to rely on the required Officer’s Certificate.

Within thirty days after the final Supplemental Transfer Date, the Depositor shall deliver to the Trustee a letter of a nationally recognized firm of independent public accountants stating whether or not the Supplemental Mortgage Loans conveyed on such Supplemental Transfer Date conform to the characteristics in Section 2.01(e)(vi), (vii) and (viii).

(h) Neither the Depositor nor the Trust will acquire or hold any Mortgage Loan that would violate the representations made by Countrywide set forth in clause (49) of Schedule III-A hereto.

SECTION 2.02.

Acceptance by Trustee of the Mortgage Loans.

(a) The Trustee acknowledges receipt of the documents identified in the Initial Certification in the form annexed hereto as Exhibit F-1 and declares that it holds and will hold such documents and the other documents delivered to it constituting the Mortgage Files, and that it holds or will hold such other assets as are included in the Trust Fund, in trust for the exclusive use and benefit of all present and future Certificateholders. The Trustee acknowledges that it will maintain possession of the Mortgage Notes in the State of California, unless otherwise permitted by the Rating Agencies.

The Trustee agrees to execute and deliver on the Closing Date to the Depositor, the Master Servicer and Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) an Initial Certification in the form annexed hereto as Exhibit F-1. Based on its review and examination, and only as to the documents identified in such Initial Certification, the Trustee acknowledges that such documents appear regular on their face and relate to such Initial Mortgage Loan. The Trustee shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face.

On or about the thirtieth (30th) day after the Closing Date, the Trustee shall deliver to the Depositor, the Master Servicer and Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) a Delay Delivery Certification with respect to the Initial Mortgage Loans in the form annexed hereto as Exhibit G-1, with any applicable exceptions noted thereon.

Not later than 90 days after the Closing Date, the Trustee shall deliver to the Depositor, the Master Servicer and Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) a Final Certification with respect to the Initial Mortgage Loans in the form annexed hereto as Exhibit H-1, with any applicable exceptions noted thereon. If, in the course of such review, the Trustee finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01, the Trustee shall list such as an exception in the Final Certification; provided, however that the Trustee shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates. Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall promptly correct or cure such defect within 90 days from the date it was so notified of such defect and, if Countrywide does not

II-7

correct or cure such defect within such period, Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall either (a) substitute for the related Mortgage Loan a Substitute Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03, or (b) purchase such Mortgage Loan from the Trustee within 90 days from the date Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) was notified of such defect in writing at the Purchase Price of such Mortgage Loan; provided, however, that in no event shall such substitution or purchase occur more than 540 days from the Closing Date, except that if the substitution or purchase of a Mortgage Loan pursuant to this provision is required by reason of a delay in delivery of any documents by the appropriate recording office, and there is a dispute between either the Master Servicer or Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) and the Trustee over the location or status of the recorded document, then such substitution or purchase shall occur within 720 days from the Closing Date. The Trustee shall deliver written notice to each Rating Agency within 270 days from the Closing Date indicating each Mortgage Loan (a) which has not been returned by the appropriate recording office or (b) as to which there is a dispute as to location or status of such Mortgage Loan. Such notice shall be delivered every 90 days thereafter until the related Mortgage Loan is returned to the Trustee. Any such substitution pursuant to (a) above or purchase pursuant to (b) above shall not be effected prior to the delivery to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, if any, and any substitution pursuant to (a) above shall not be effected prior to the additional delivery to the Trustee of a Request for Release substantially in the form of Exhibit N. No substitution is permitted to be made in any calendar month after the Determination Date for such month. The Purchase Price for any such Mortgage Loan shall be deposited by Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) in the Certificate Account on or prior to the Distribution Account Deposit Date for the Distribution Date in the month following the month of repurchase and, upon receipt of such deposit and certification with respect thereto in the form of Exhibit N hereto, the Trustee shall release the related Mortgage File to Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) and shall execute and deliver at Countrywide’s (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) request such instruments of transfer or assignment prepared by Countrywide, in each case without recourse, as shall be necessary to vest in Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna), or its designee, the Trustee’s interest in any Mortgage Loan released pursuant hereto. If pursuant to the foregoing provisions Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) repurchases an Initial Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer shall either (i) cause MERS to execute and deliver an assignment of the Mortgage in recordable form to transfer the Mortgage from MERS to Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) or its designee and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and regulations or (ii) cause MERS to designate on the MERS® System Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) or its designee as the beneficial holder of such Mortgage Loan.

(b) Upon delivery of the Supplemental Mortgage Loans pursuant to a Supplemental Transfer Agreement, the Trustee shall acknowledge receipt of the documents identified in any Supplemental Certification in the form annexed hereto as Exhibit F-2 and declare that it will hold such documents and the other documents delivered to it constituting the Mortgage Files, and that it will hold such other assets as are included in the Trust Fund, in trust for the exclusive use and benefit of all present and future Certificateholders. The Trustee acknowledges that it will maintain possession of the Mortgage Notes in the State of California, unless otherwise permitted by the Rating Agencies.

The Trustee agrees to execute and deliver on the Supplemental Transfer Date to the Depositor, the Master Servicer and Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) a Supplemental Certification in the form annexed hereto as Exhibit F-2. Based

II-8

on its review and examination, and only as to the documents identified in such Supplemental Certification, the Trustee shall acknowledge that such documents appear regular on their face and relate to such Supplemental Mortgage Loan. The Trustee shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face.

On or about the twentieth (20th) day after the Supplemental Transfer Date, the Trustee shall deliver to the Depositor, the Master Servicer and Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) a Delay Delivery Certification with respect to the Supplemental Mortgage Loans in the form annexed hereto as Exhibit G-2, with any applicable exceptions noted thereon.

Not later than 90 days after the final Supplemental Transfer Date, the Trustee shall deliver to the Depositor, the Master Servicer and Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) a Final Certification with respect to the Supplemental Mortgage Loans in the form annexed hereto as Exhibit H-2, with any applicable exceptions noted thereon.

(c) If, in the course of such review of the Mortgage Files relating to the Supplemental Mortgage Loans, the Trustee finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01, the Trustee shall list such as an exception in the Final Certification; provided, however that the Trustee shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates. Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall promptly correct or cure such defect within 90 days from the date it was so notified of such defect and, if Countrywide does not correct or cure such defect within such period, Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall either (a) substitute for the related Mortgage Loan a Substitute Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03, or (b) purchase such Mortgage Loan from the Trustee within 90 days from the date Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) was notified of such defect in writing at the Purchase Price of such Mortgage Loan; provided, however, that in no event shall such substitution or purchase occur more than 540 days from the Closing Date, except that if the substitution or purchase of a Mortgage Loan pursuant to this provision is required by reason of a delay in delivery of any documents by the appropriate recording office, and there is a dispute between either the Master Servicer or Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) and the Trustee over the location or status of the recorded document, then such substitution or purchase shall occur within 720 days from the Closing Date. The Trustee shall deliver written notice to each Rating Agency within 270 days from the Closing Date indicating each Mortgage Loan (a) which has not been returned by the appropriate recording office or (b) as to which there is a dispute as to location or status of such Mortgage Loan. Such notice shall be delivered every 90 days thereafter until the related Mortgage Loan is returned to the Trustee. Any such substitution pursuant to (a) above or purchase pursuant to (b) above shall not be effected prior to the delivery to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, if any, and any substitution pursuant to (a) above shall not be effected prior to the additional delivery to the Trustee of a Request for Release substantially in the form of Exhibit N. No substitution is permitted to be made in any calendar month after the Determination Date for such month. The Purchase Price for any such Mortgage Loan shall be deposited by Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) in the Certificate Account on or prior to the Distribution Account Deposit Date for the Distribution Date in the month following the month of repurchase and, upon receipt of such deposit and

II-9

certification with respect thereto in the form of Exhibit N hereto, the Trustee shall release the related Mortgage File to Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) and shall execute and deliver at Countrywide’s (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) request such instruments of transfer or assignment prepared by Countrywide, in each case without recourse, as shall be necessary to vest in Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna), or a designee, the Trustee’s interest in any Mortgage Loan released pursuant hereto. If pursuant to the foregoing provisions Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) repurchases a Supplemental Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer shall either (i) cause MERS to execute and deliver an assignment of the Mortgage in recordable form to transfer the Mortgage from MERS to Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and regulations or (ii) cause MERS to designate on the MERS® System Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) or its designee as the beneficial holder of such Mortgage Loan.

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

(e) It is understood and agreed that the respective obligations of each Seller to substitute for or to purchase any Mortgage Loan sold to the Depositor by it which does not meet the requirements of Section 2.01 above shall constitute the sole remedy respecting such defect available to the Trustee, the Depositor and any Certificateholder against that Seller.

(f) [Reserved].

SECTION 2.03.

Representations, Warranties and Covenants of the Sellers and Master Servicer.

(a) Countrywide hereby makes the representations and warranties set forth in (i) Schedule II-A, Schedule II-B, Schedule II-C and Schedule II-D hereto, and by this reference incorporated herein, to the Depositor, the Master Servicer and the Trustee, as of the Closing Date, (ii) Schedule III-A hereto, and by this reference incorporated herein, to the Depositor, the Master Servicer and the Trustee, as of the Closing Date, or if so specified therein, as of the Initial Cut-off Date with respect to all of the Initial Mortgage Loans and as of the related Supplemental Cut-off Date with respect to all of the Supplemental Mortgage Loans, and (iii) Schedule III-B hereto, and by this reference incorporated herein, to the Depositor, the Master Servicer and the Trustee, as of the Closing Date, or if so specified therein, as of the Initial Cut-off Date with respect to the Initial Mortgage Loans that are Countrywide Mortgage Loans and as of the related Supplemental Cut-off Date with respect to the Supplemental Mortgage Loans that are Countrywide Mortgage Loans. Park Granada hereby makes the representations and warranties set forth in (i) Schedule II-B hereto, and by this reference incorporated herein, to the Depositor, the Master Servicer and the Trustee, as of the Closing Date and (ii) Schedule III-C hereto, and by this reference incorporated herein, to the Depositor, the Master Servicer and the Trustee, as of the Closing Date, or if so specified therein, as of the Initial Cut-off Date with respect to the Initial Mortgage Loans that are Park Granada Mortgage Loans and as of the related Supplemental Cut-off Date with respect to the Supplemental Mortgage Loans that are Park Granada Mortgage Loans.

(b) The Master Servicer hereby makes the representations and warranties set forth in Schedule IV hereto, and by this reference incorporated herein, to the Depositor and the Trustee, as of the Closing Date.

(c) Upon discovery by any of the parties hereto of a breach of a representation or warranty with respect to a Mortgage Loan made pursuant to Section 2.03(a) or a breach of a representation or warranty with respect to a Supplemental Mortgage Loan under Section 2.01(e)(i) that materially and adversely affects the interests of the Certificateholders in that Mortgage Loan, the party discovering such breach shall give prompt notice thereof to the other parties. Each Seller hereby covenants that within 90 days of the earlier of its discovery or its receipt of written notice from any party of a breach of any representation or warranty with respect to a Mortgage Loan sold by it pursuant to Section 2.03(a) and with respect to a breach of a representation and warranty with respect to a Supplemental Mortgage Loan sold by it under Section 2.01(e)(i) which materially and adversely affects the interests of the Certificateholders in that Mortgage Loan, it shall cure such breach in all material respects, and if such breach is not so cured, shall, (i) if such 90-day period expires prior to the second anniversary of the Closing Date, remove such Mortgage Loan (a “Deleted Mortgage Loan”) from the Trust Fund and substitute in its place a Substitute Mortgage Loan, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below; provided, however, that any such substitution pursuant to (i) above shall not be effected prior to the delivery to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, if any, and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery to the Trustee of a Request for Release substantially in the form of Exhibit N and the Mortgage File for any such Substitute Mortgage Loan. The Seller repurchasing a Mortgage Loan pursuant to this Section 2.03(c) shall promptly reimburse the Master Servicer and the Trustee for any expenses reasonably incurred by the Master Servicer or the Trustee in respect of enforcing the remedies for such breach. With respect to the representations and warranties described in this Section which are made to the best of a Seller’s knowledge, if it is discovered by either the Depositor, a Seller or the Trustee that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interests of the Certificateholders therein, notwithstanding that Seller’s lack of knowledge with respect to the substance of such representation or warranty, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

With respect to any Substitute Mortgage Loan or Loans, sold to the Depositor by a Seller, Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) shall deliver to the Trustee for the benefit of the Certificateholders the Mortgage Note, the Mortgage, the related assignment of the Mortgage, and such other documents and agreements as are required by Section 2.01, with the Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01. No substitution is permitted to be made in any calendar month after the Determination Date for such month. Scheduled Payments due with respect to Substitute Mortgage Loans in the month of substitution shall not

II-11

be part of the Trust Fund and will be retained by the related Seller on the next succeeding Distribution Date. For the month of substitution, distributions to Certificateholders will include the monthly payment due on any Deleted Mortgage Loan for such month and thereafter that Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Master Servicer shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Substitute Mortgage Loan or Loans and the Master Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee. Upon such substitution, the Substitute Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the related Seller shall be deemed to have made with respect to such Substitute Mortgage Loan or Loans, as of the date of substitution, the representations and warranties made pursuant to Section 2.03(a) with respect to such Mortgage Loan. Upon any such substitution and the deposit to the Certificate Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Trustee shall release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the related Seller and shall execute and deliver at such Seller’s direction such instruments of transfer or assignment prepared by Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna), in each case without recourse, as shall be necessary to vest title in that Seller, or its designee, the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

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

In the event that a Seller shall have repurchased a Mortgage Loan, the Purchase Price therefor shall be deposited in the Certificate Account pursuant to Section 3.05 on or before the Distribution Account Deposit Date for the Distribution Date in the month following the month during which that Seller became obligated hereunder to repurchase or replace such Mortgage Loan and upon such deposit of the Purchase Price, the delivery of the Opinion of Counsel required by Section 2.05 and receipt of a Request for Release in the form of Exhibit N hereto, the Trustee shall release the related Mortgage File held for the benefit of the Certificateholders to such Person, and the Trustee shall execute and deliver at such Person’s direction such instruments of transfer or assignment prepared by such Person, in each case without recourse, as shall be necessary to transfer title from the Trustee. It is understood and agreed that the obligation under this Agreement of any Person to cure, repurchase or replace any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedy against such Persons respecting such breach available to Certificateholders, the Depositor or the Trustee on their behalf.

The representations and warranties made pursuant to this Section 2.03 shall survive delivery of the respective Mortgage Files to the Trustee for the benefit of the Certificateholders.

II-12

SECTION 2.04.

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

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

The Depositor hereby assigns, transfers and conveys to the Trustee all of its rights with respect to the Mortgage Loans including, without limitation, the representations and warranties of each Seller made pursuant to Section 2.03(a)(ii) hereof, together with all rights of the Depositor to require each Seller to cure any breach thereof or to repurchase or substitute for any affected Mortgage Loan in accordance with this Agreement.

It is understood and agreed that the representations and warranties set forth in this Section 2.04 shall survive delivery of the Mortgage Files to the Trustee. Upon discovery by the Depositor or the Trustee of a breach of any of the foregoing representations and warranties set forth in this Section 2.04 (referred to herein as a “breach”), which breach materially and adversely affects the interest of the Certificateholders, the party discovering such breach shall give prompt written notice to the others and to each Rating Agency.

SECTION 2.05.

Delivery of Opinion of Counsel in Connection with Substitutions.

(a) Notwithstanding any contrary provision of this Agreement, no substitution pursuant to Section 2.02 or Section 2.03 shall be made more than 90 days after the Closing Date unless Countrywide delivers to the Trustee an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of either the Trustee or the Trust Fund, addressed to the Trustee, to the effect that such substitution will not (i) result in the imposition of the tax on “prohibited transactions” on the Trust Fund or contributions after the Startup Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively, or (ii) cause each REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding.

(b) Upon discovery by the Depositor, a Seller, the Master Servicer, or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall promptly (and in any event within five (5) Business Days of discovery) give written notice thereof to the other parties. In connection therewith, the Trustee shall require Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna), at its option, to either (i) substitute, if the conditions in Section 2.03(c) with respect to substitutions are satisfied, a Substitute Mortgage Loan for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90 days of such discovery in the same manner as it would a Mortgage Loan for a breach of representation or warranty made pursuant to Section 2.03. The Trustee shall reconvey to Countrywide the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty contained in Section 2.03.

SECTION 2.06.

Execution and Delivery of Certificates.

The Trustee acknowledges the transfer and assignment to it of the Trust Fund and, concurrently with such transfer and assignment, has executed and delivered to or upon the order of the Depositor, the Certificates in authorized denominations evidencing directly or indirectly the entire ownership of the Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the rights referred

II-13

to above for the benefit of all present and future Holders of the Certificates and to perform the duties set forth in this Agreement, to the end that the interests of the Holders of the Certificates may be adequately and effectively protected.

SECTION 2.07.

REMIC Matters.

The Preliminary Statement sets forth the designations and “latest possible maturity date” for federal income tax purposes of all interests created hereby. The “Startup Day” for purposes of the REMIC Provisions shall be the Closing Date. The “tax matters person” with respect to each REMIC hereunder shall be the Trustee and the Trustee shall hold the Tax Matters Person Certificate. Each REMIC’s fiscal year shall be the calendar year.

SECTION 2.08.

Covenants of the Master Servicer.

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

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

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

ARTICLE III

ADMINISTRATION AND SERVICING

OF MORTGAGE LOANS

SECTION 3.01.

Master Servicer to Service Mortgage Loans.

For and on behalf of the Certificateholders, the Master Servicer shall service and administer the Mortgage Loans in accordance with the terms of this Agreement and customary and usual standards of practice of prudent mortgage loan servicers. In connection with such servicing and administration, the Master Servicer shall have full power and authority, acting alone and/or through Subservicers as provided in Section 3.02 hereof, subject to the terms hereof (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages (but only in the manner provided in this Agreement), (iii) to collect any Insurance Proceeds and other Liquidation Proceeds (which, for the purpose of this Section, includes any Subsequent Recoveries), and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan; provided that the Master Servicer shall not take any action that is inconsistent with or prejudices the interests of the Trust Fund or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee and the Certificateholders under this Agreement. The Master Servicer shall represent and protect the interests of the Trust Fund in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan, and shall not make or permit any modification, waiver or amendment of any Mortgage Loan which would cause any REMIC created hereunder to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code. Without limiting the generality of the foregoing, the Master Servicer, in its own name or in the name of the Depositor and the Trustee, is hereby authorized and empowered by the Depositor and the Trustee, when the Master Servicer believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to the Mortgage Loans, and with respect to the Mortgaged Properties held for the benefit of the Certificateholders. The Master Servicer shall prepare and deliver to the Depositor and/or the Trustee such documents requiring execution and delivery by either or both of them as are necessary or appropriate to enable the Master Servicer to service and administer the Mortgage Loans to the extent that the Master Servicer is not permitted to execute and deliver such documents pursuant to the preceding sentence. Upon receipt of such documents, the Depositor and/or the Trustee shall execute such documents and deliver them to the Master Servicer. The Master Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of the Subservicer, when the Master Servicer or the Subservicer, as the case may be, believes it appropriate in its best judgment to register any Mortgage Loan on the MERS® System, or cause the removal from the registration of any Mortgage Loan on the MERS® System, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns.

In accordance with the standards of the preceding paragraph, the Master Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties, which advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.06, and further as provided in Section 3.08. The costs incurred by the Master Servicer, if any, in effecting the timely payments of taxes and assessments on the Mortgaged Properties and related insurance premiums shall not, for the purpose of

III-1

calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balances of the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

SECTION 3.02.

Subservicing; Enforcement of the Obligations of Subservicers.

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

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

SECTION 3.03.

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

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

SECTION 3.04.

Trustee to Act as Master Servicer.

In the event that the Master Servicer shall for any reason no longer be the Master Servicer hereunder (including by reason of an Event of Default or termination by the Depositor), the Trustee or its successor shall thereupon assume all of the rights and obligations of the Master Servicer hereunder arising thereafter (except that the Trustee shall not be (i) liable for losses of the Master Servicer pursuant to Section 3.09 hereof or any acts or omissions of the predecessor Master Servicer hereunder), (ii) obligated to make Advances if it is prohibited from doing so by applicable law, (iii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder including, but not limited to, repurchases or substitutions of Mortgage Loans pursuant to Section 2.02 or 2.03 hereof, (iv) responsible for expenses of the Master Servicer pursuant to Section 2.03 or (v) deemed to have made any representations and warranties of the Master Servicer hereunder). Any such assumption shall be subject to Section 7.02

III-2

hereof. If the Master Servicer shall for any reason no longer be the Master Servicer (including by reason of any Event of Default or termination by the Depositor), the Trustee or its successor shall succeed to any rights and obligations of the Master Servicer under each subservicing agreement.

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

SECTION 3.05.

Collection of Mortgage Loan Payments; the Certificate Account; the Distribution Account; the Pre-Funding Account and the Capitalized Interest Account.

(a) The Master Servicer shall make reasonable efforts in accordance with the customary and usual standards of practice of prudent mortgage servicers to collect all payments called for under the terms and provisions of the Mortgage Loans to the extent such procedures shall be consistent with this Agreement and the terms and provisions of any related Required Insurance Policy. Consistent with the foregoing, the Master Servicer may in its discretion (i) waive any late payment charge or any prepayment charge or penalty interest in connection with the prepayment of a Mortgage Loan and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 180 days; provided, however, that the Master Servicer cannot extend the maturity of any such Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any such arrangement, the Master Servicer shall make Advances on the related Mortgage Loan in accordance with the provisions of Section 4.01 during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements. The Master Servicer shall not be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law.

(b) The Master Servicer shall establish and maintain a Certificate Account into which the Master Servicer shall deposit or cause to be deposited no later than two Business Days after receipt (or, if (i) the current short-term credit rating of Countrywide from S&P is reduced below “A-2” or, if Countrywide does not have a short-term credit rating from S&P, the current long-term credit rating of Countrywide from S&P is reduced below “BBB+”, (ii) the current long-term credit rating of Countrywide from Xxxxx’x is reduced below “A3” or (iii) the current long-term credit rating of Countrywide from Fitch is reduced below “A-”, the Master Servicer shall deposit or cause to be deposited on a daily basis within one Business Day of receipt), except as otherwise specifically provided in this Agreement, the following payments and collections remitted by Subservicers or received by it in respect of Mortgage Loans subsequent to the Cut-off Date (other than in respect of principal and interest due on the Mortgage Loans on or before the Cut-off Date) and the following amounts required to be deposited under this Agreement:

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

(ii) all payments on account of interest on the Mortgage Loans, net of the Master Servicing Fee, Prepayment Interest Excess and any lender-paid mortgage insurance premiums;

III-3

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

(iv) any amount required to be deposited by the Master Servicer or the Depositor pursuant to Section 3.05(e) in connection with any losses on Permitted Investments for which it is responsible;

(v) any amounts required to be deposited by the Master Servicer pursuant to Section 3.09(c) and in respect of net monthly rental income from REO Property pursuant to Section 3.11 hereof;

(vi) all Substitution Adjustment Amounts;

(vii) all Advances made by the Master Servicer pursuant to Section 4.01; and

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

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

The foregoing requirements for remittance by the Master Servicer shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of Prepayment Charges, late payment charges or assumption fees, if collected, need not be remitted by the Master Servicer. In the event that the Master Servicer shall remit any amount not required to be remitted, it may at any time withdraw or direct the institution maintaining the Certificate Account to withdraw such amount from the Certificate Account, any provision herein to the contrary notwithstanding. Such withdrawal or direction may be accomplished by delivering written notice thereof to the Trustee or such other institution maintaining the Certificate Account which describes the amounts deposited in error in the Certificate Account. The Master Servicer shall maintain adequate records with respect to all withdrawals made pursuant to this Section. All funds deposited in the Certificate Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 3.08.

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

(i) the aggregate amount remitted by the Master Servicer to the Trustee pursuant to Section 3.08(a)(ix);

(ii) any amount deposited by the Master Servicer or the Depositor pursuant to Section 3.05(e) in connection with any losses on Permitted Investments for which it is responsible; and

III-4

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

In the event that the Master Servicer shall remit any amount not required to be remitted, it may at any time direct the Trustee to withdraw such amount from the Distribution Account, any provision herein to the contrary notwithstanding. Such direction may be accomplished by delivering an Officer’s Certificate to the Trustee which describes the amounts deposited in error in the Distribution Account. All funds deposited in the Distribution Account shall be held by the Trustee in trust for the Certificateholders until disbursed in accordance with this Agreement or withdrawn in accordance with Section 3.08. In no event shall the Trustee incur liability for withdrawals from the Distribution Account at the direction of the Master Servicer.

(e) Each institution at which the Certificate Account, the Pre-Funding Account, the Capitalized Interest Account or the Distribution Account is maintained shall invest the funds therein as directed in writing by the Master Servicer in Permitted Investments, which shall mature not later than (i) in the case of the Certificate Account, the Pre-Funding Account or the Capitalized Interest Account the second Business Day next preceding the related Distribution Account Deposit Date (except that if such Permitted Investment is an obligation of the institution that maintains such account, then such Permitted Investment shall mature not later than the Business Day next preceding such Distribution Account Deposit Date) and (ii) in the case of the Distribution Account, the Business Day next preceding the Distribution Date (except that if such Permitted Investment is an obligation of the institution that maintains such fund or account, then such Permitted Investment shall mature not later than such Distribution Date) and, in each case, shall not be sold or disposed of prior to its maturity. All such Permitted Investments shall be made in the name of the Trustee, for the benefit of the Certificateholders. All income and gain net of any losses realized from any such investment of funds on deposit in the Certificate Account, or the Distribution Account shall be for the benefit of the Master Servicer as servicing compensation and shall be remitted to it monthly as provided herein. The amount of any realized losses in the Certificate Account or the Distribution Account incurred in any such account in respect of any such investments shall promptly be deposited by the Master Servicer in the Certificate Account or paid to the Trustee for deposit into the Distribution Account, as applicable. The amount of any losses in the Pre-Funding Account or the Capitalized Interest Account incurred in respect of any such investments shall promptly be deposited by the Depositor in the Pre-Funding Account or the Capitalized Interest Account, as applicable. All income or gain (net of any losses) realized from any such investment of funds on deposit in the Capitalized Interest Account shall be credited to the Capitalized Interest Account. The Trustee in its fiduciary capacity shall not be liable for the amount of any loss incurred in respect of any investment or lack of investment of funds held in the Certificate Account, the Pre-Funding Account, the Capitalized Interest Account or the Distribution Account and made in accordance with this Section 3.05.

(f) The Master Servicer shall give notice to the Trustee, each Seller, each Rating Agency and the Depositor of any proposed change of the location of the Certificate Account prior to any change thereof. The Trustee shall give notice to the Master Servicer, each Seller, each Rating Agency and the Depositor of any proposed change of the location of the Distribution Account, the Pre-Funding Account or the Capitalized Interest Account, prior to any change thereof.

(g) The Trustee shall establish and maintain, on behalf of the Certificateholders, the Pre-Funding Account. On the Closing Date Countrywide shall remit the Pre-Funded Amount to the Trustee for deposit in the Pre-Funding Account. On each Supplemental Transfer Date, upon satisfaction of the conditions for such Supplemental Transfer Date set forth in Section 2.01(e), with respect to the related Supplemental Transfer Agreement, the Trustee shall pay to each Seller selling Supplemental Mortgage Loans to the Depositor on such Supplemental Transfer Date the portion of the Aggregate

III-5

Supplemental Transfer Amount held in escrow pursuant to Section 2.01(e) as payment of the purchase price for the Supplemental Mortgage Loans sold by such Seller. If at any time the Depositor becomes aware that the Cut-off Date Stated Principal Balance of Supplemental Mortgage Loans reflected on any Supplemental Transfer Agreement exceeds the actual Cut-off Date Stated Principal Balance of the relevant Supplemental Mortgage Loans, the Depositor may so notify the Trustee and the Trustee shall redeposit into the Pre-Funding Account the excess reported to it by the Depositor.

If any funds remain in the Pre-Funding Account at the end of the Funding Period, to the extent that they represent earnings on the amounts originally deposited into the Pre-Funding Account, the Trustee shall distribute them to the order of the Depositor. The remaining funds shall be transferred to the Distribution Account to be included as part of principal distributions to the Class PO Certificates, to the extent of the Remaining PO Pre-Funded Amount and to the other Classes of Senior Certificates, to the extent of the Remaining Non-PO Pre-Funded Amount, as applicable.

(h) The Trustee shall establish and maintain, on behalf of the Certificateholders, the Capitalized Interest Account. On the Closing Date, Countrywide shall remit the Capitalized Interest Deposit to the Trustee for deposit in the Capitalized Interest Account. On each Distribution Account Deposit Date related to a Funding Period Distribution Date, the Trustee shall transfer from the Capitalized Interest Account to the Distribution Account an amount equal to the Capitalized Interest Requirement (which, to the extent required, may include investment earnings on amounts on deposit therein) for the related Distribution Date.

On each Supplemental Transfer Date, upon satisfaction of the conditions for such Supplemental Transfer Date set forth in Section 2.l0(e), the Trustee shall withdraw from the Capitalized Interest Account the Capitalized Interest Release Amount for such Supplemental Transfer Date and distribute the amount to the order of Countrywide. If any funds remain in the Capitalized Interest Account at the end of the Distribution Account Deposit Date for the last Funding Period Distribution Date, the Trustee shall distribute any such remaining funds to the order of Countrywide on the last Funding Period Distribution Date.

SECTION 3.06.

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

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

(b) Withdrawals of amounts so collected from the Escrow Accounts may be made only to effect timely payment of taxes, assessments, hazard insurance premiums, condominium or PUD association dues, or comparable items, to reimburse the Master Servicer out of related collections for any payments made pursuant to Sections 3.01 hereof (with respect to taxes and assessments and insurance premiums) and 3.09 hereof (with respect to hazard insurance), to refund to any Mortgagors any sums determined to be overages, to pay interest, if required by law or the terms of the related Mortgage or Mortgage Note, to Mortgagors on balances in the Escrow Account or to clear and terminate the Escrow Account at the termination of this Agreement in accordance with Section 9.01 hereof. The Escrow Accounts shall not be a part of the Trust Fund.

(c) The Master Servicer shall advance any payments referred to in Section 3.06(a) that are not timely paid by the Mortgagors on the date when the tax, premium or other cost for which such

III-6

payment is intended is due, but the Master Servicer shall be required so to advance only to the extent that such advances, in the good faith judgment of the Master Servicer, will be recoverable by the Master Servicer out of Insurance Proceeds, Liquidation Proceeds or otherwise.

SECTION 3.07.

Access to Certain Documentation and Information Regarding the Mortgage Loans.

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

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

SECTION 3.08.

Permitted Withdrawals from the Certificate Account and the Distribution Account.

(a) The Master Servicer may from time to time make withdrawals from the Certificate Account for the following purposes:

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

(ii) to reimburse each of the Master Servicer and the Trustee for unreimbursed Advances made by it, such right of reimbursement pursuant to this subclause (ii) being limited to amounts received on the Mortgage Loan(s) in respect of which any such Advance was made;

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

(v) to reimburse the Master Servicer for (a) unreimbursed Servicing Advances, the Master Servicer’s right to reimbursement pursuant to this clause (a) with respect to any Mortgage Loan being limited to amounts received on such Mortgage Loan(s) which represent late recoveries of the payments for which such advances were made pursuant to Section 3.01 or Section 3.06 and (b) for unpaid Master Servicing Fees as provided in Section 3.11 hereof;

III-7

(vi) to pay to the purchaser, with respect to each Mortgage Loan or property acquired in respect thereof that has been purchased pursuant to Section 2.02, 2.03 or 3.11, all amounts received thereon after the date of such purchase;

(vii) to reimburse the Sellers, the Master Servicer or the Depositor for expenses incurred by any of them and reimbursable pursuant to Section 6.03 hereof;

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

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

(x) to clear and terminate the Certificate Account upon termination of this Agreement pursuant to Section 9.01 hereof.

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

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

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

(vi) to clear and terminate the Distribution Account upon termination of the Agreement pursuant to Section 9.01 hereof.

SECTION 3.09.

Maintenance of Hazard Insurance; Maintenance of Primary Insurance Policies.

(a) The Master Servicer shall cause to be maintained, for each Mortgage Loan, hazard insurance with extended coverage in an amount that is at least equal to the lesser of (i) the maximum insurable value of the improvements securing such Mortgage Loan or (ii) the greater of (y) the outstanding principal balance of the Mortgage Loan and (z) an amount such that the proceeds of such policy shall be sufficient to prevent the Mortgagor and/or the mortgagee from becoming a co-insurer. Each such policy of standard hazard insurance shall contain, or have an accompanying endorsement that contains, a standard mortgagee clause. Any amounts collected by the Master Servicer under any such policies (other than the amounts to be applied to the restoration or repair of the related Mortgaged Property or amounts released to the Mortgagor in accordance with the Master Servicer’s normal servicing procedures) shall be deposited in the Certificate Account. Any cost incurred by the Master Servicer in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trustee for their benefit, be added to the principal balance of the Mortgage Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs shall be recoverable by the Master Servicer out of late payments by the related Mortgagor or out of the proceeds of liquidation of the Mortgage Loan or Subsequent Recoveries to the extent permitted by Section 3.08 hereof. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor or maintained on property acquired in respect of a Mortgage other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If the Mortgaged Property is located at the time of origination of the Mortgage Loan in a federally designated special flood hazard area and such area is participating in the national flood insurance program, the Master Servicer shall cause flood insurance to be maintained with respect to such Mortgage Loan. Such flood insurance shall be in an amount equal to the least of (i) the outstanding principal balance of the related Mortgage Loan, (ii) the replacement value of the improvements which are part of such Mortgaged Property, and (iii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program.

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

Except with respect to any Lender PMI Mortgage Loans, the Master Servicer shall not be required to maintain any Primary Insurance Policy (i) with respect to any Mortgage Loan with a Loan-to-Value Ratio less than or equal to 80% as of any date of determination or, based on a new appraisal, the principal balance of such Mortgage Loan represents 80% or less of the new appraised value or (ii) if maintaining such Primary Insurance Policy is prohibited by applicable law. With respect to the Lender PMI Mortgage Loans, the Master Servicer shall maintain the Primary Insurance Policy for the life of such Mortgage Loans, unless otherwise provided for in the related Mortgage Note or prohibited by law.

III-9

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

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

SECTION 3.10.

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

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

(b) Subject to the Master Servicer’s duty to enforce any due-on-sale clause to the extent set forth in Section 3.10(a) hereof, in any case in which a Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage that requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the Mortgage Loan, the Master Servicer shall prepare and deliver or cause to be prepared and delivered to the Trustee for signature and shall direct, in writing, the Trustee to execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person. In connection with any such assumption, no material term of the Mortgage Note may be changed. In addition, the substitute Mortgagor and the Mortgaged Property must be acceptable to the Master Servicer in accordance with its

III-10

underwriting standards as then in effect. Together with each such substitution, assumption or other agreement or instrument delivered to the Trustee for execution by it, the Master Servicer shall deliver an Officer’s Certificate signed by a Servicing Officer stating that the requirements of this subsection have been met in connection therewith. The Master Servicer shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the Trustee the original of such substitution or assumption agreement, which in the case of the original shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Any fee collected by the Master Servicer for entering into an assumption or substitution of liability agreement will be retained by the Master Servicer as additional servicing compensation.

SECTION 3.11.

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

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

With respect to any REO Property, the deed or certificate of sale shall be taken in the name of the Trustee for the benefit of the Certificateholders, or its nominee, on behalf of the Certificateholders. The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. The Master Servicer shall ensure that the title to such REO Property references the Pooling and Servicing Agreement and the Trustee’s capacity thereunder. The Master Servicer shall allow any REO Property that was subject to a lease at the time of acquisition through foreclosure or deed-in-lieu of foreclosure to continue to be rented pursuant to such lease, but upon the expiration of such lease, the Master Servicer shall not take any action to rent the related REO Property. Pursuant to its efforts to sell such REO Property, the Master Servicer shall either itself or through an agent selected by the Master Servicer protect and conserve such REO Property in the same manner and to such extent as is customary in the locality where such REO Property is located. The Master Servicer shall prepare for and deliver to the Trustee a statement with respect to each REO Property that has been rented showing the aggregate rental income received and all expenses incurred in connection with the maintenance of such REO Property at such times as is necessary to enable the Trustee

III-11

to comply with the reporting requirements of the REMIC Provisions. Any net monthly income from such REO Property shall be deposited in the Certificate Account no later than the close of business on each Determination Date. The Master Servicer shall perform the tax reporting and withholding required by Sections 1445 and 6050J of the Code with respect to foreclosures and abandonments, the tax reporting required by Section 6050H of the Code with respect to the receipt of mortgage interest from individuals and any tax reporting required by Section 6050P of the Code with respect to the cancellation of indebtedness by certain financial entities, by preparing such tax and information returns as may be required, in the form required, and delivering the same to the Trustee for filing.

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

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

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

III-12

The proceeds from any liquidation of a Mortgage Loan, as well as any income from an REO Property, will be applied in the following order of priority: first, to reimburse the Master Servicer for any related unreimbursed Servicing Advances and Master Servicing Fees; second, to reimburse the Master Servicer or the Trustee for any unreimbursed Advances; third, to reimburse the Certificate Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by the Master Servicer or the Trustee pursuant to Section 3.08(a)(iii) that related to such Mortgage Loan; fourth, to accrued and unpaid interest (to the extent no Advance has been made for such amount or any such Advance has been reimbursed) on the Mortgage Loan or related REO Property, at the Adjusted Net Mortgage Rate to the Due Date occurring in the month in which such amounts are required to be distributed; and fifth, as a recovery of principal of the Mortgage Loan. Excess Proceeds, if any, from the liquidation of a Liquidated Mortgage Loan will be retained by the Master Servicer as additional servicing compensation pursuant to Section 3.14.

The Master Servicer, in its sole discretion, shall have the right to purchase for its own account from the Trust Fund any Mortgage Loan which is 151 days or more delinquent at a price equal to the Purchase Price; provided, however, that the Master Servicer may only exercise this right on or before the next to the last day of the calendar month in which such Mortgage Loan became 151 days delinquent (such month, the “Eligible Repurchase Month”); provided further, that any such Mortgage Loan which becomes current but thereafter becomes delinquent may be purchased by the Master Servicer pursuant to this Section in any ensuing Eligible Repurchase Month. The Purchase Price for any Mortgage Loan purchased hereunder shall be deposited in the Certificate Account and the Trustee, upon receipt of a certificate from the Master Servicer in the form of Exhibit N hereto, shall release or cause to be released to the purchaser of such Mortgage Loan the related Mortgage File and shall execute and deliver such instruments of transfer or assignment prepared by the purchaser of such Mortgage Loan, in each case without recourse, as shall be necessary to vest in the purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto and the purchaser of such Mortgage Loan shall succeed to all the Trustee’s right, title and interest in and to such Mortgage Loan and all security and documents related thereto. Such assignment shall be an assignment outright and not for security. The purchaser of such Mortgage Loan shall thereupon own such Mortgage Loan, and all security and documents, free of any further obligation to the Trustee or the Certificateholders with respect thereto.

(b) Countrywide is permitted to solicit Mortgagors for reductions to the Mortgage Rates of their respective Mortgage Loans so long as the Mortgagors are not selected for solicitation based on the inclusion of the related Mortgage Loans in the Trust Fund. If a Mortgagor requests a reduction to the Mortgage Rate for the related Mortgage Loan, the Master Servicer shall agree to a reduction in the Mortgage Rate of that Mortgage Loan (the “Modified Mortgage Loan”) if (i) no monetary default exists with respect to such Mortgage Loan and (ii) Countrywide, in its corporate capacity, agrees to purchase the Modified Mortgage Loan from the Trust Fund immediately following the modification as described below. Effective immediately after the modification, and, in any event, on the same Business Day on which the modification occurs, all interest of the Trustee in the Modified Mortgage Loan shall automatically be deemed transferred and assigned to Countrywide and all benefits and burdens of ownership thereof, including the right to accrued interest thereon from the date of modification and the risk of default thereon, shall pass to Countrywide. The Master Servicer shall promptly deliver to the Trustee a certification of a Servicing Officer to the effect that all requirements of this paragraph have been satisfied with respect to the Modified Mortgage Loan. For federal income tax purposes, the Trustee shall account for such purchase as a prepayment in full of the Modified Mortgage Loan.

Countrywide shall remit the Purchase Price for any Modified Mortgage Loan to the Master Servicer for deposit into the Certificate Account pursuant to Section 3.05 within one Business Day after the purchase of the Modified Mortgage Loan. Upon receipt by the Trustee of written notification of any such deposit signed by a Servicing Officer, the Trustee shall release to Countrywide the related

III-13

Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in Countrywide any Modified Mortgage Loan previously transferred and assigned pursuant hereto. Countrywide covenants and agrees to indemnify the Trust Fund against any liability for any “prohibited transaction” taxes and any related interest, additions, and penalties imposed on the Trust Fund established hereunder as a result of any modification of a Mortgage Loan effected pursuant to this subsection (b), any holding of a Modified Mortgage Loan by the Trust Fund or any purchase of a Modified Mortgage Loan by Countrywide (but such obligation shall not prevent Countrywide or any other appropriate Person from in good faith contesting any such tax in appropriate proceedings and shall not prevent Countrywide from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). Countrywide shall have no right of reimbursement for any amount paid pursuant to the foregoing indemnification, except to the extent that the amount of any tax, interest, and penalties, together with interest thereon, is refunded to the Trust Fund or Countrywide. Nothing in this Section 3.11(b) restricts the ability of the Master Servicer to modify a Mortgage Loan in a manner that is consistent with the servicing standard set forth in Section 3.01; provided, however, that Countrywide shall have no obligation to purchase any such modified Mortgage Loan.

SECTION 3.12.

Trustee to Cooperate; Release of Mortgage Files.

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

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

III-14

SECTION 3.13.

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

Notwithstanding any other provisions of this Agreement, the Master Servicer shall transmit to the Trustee as required by this Agreement all documents and instruments in respect of a Mortgage Loan coming into the possession of the Master Servicer from time to time and shall account fully to the Trustee for any funds received by the Master Servicer or which otherwise are collected by the Master Servicer as Liquidation Proceeds, Insurance Proceeds or Subsequent Recoveries in respect of any Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, the Master Servicer in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds and any Subsequent Recoveries, including but not limited to, any funds on deposit in the Certificate Account, shall be held by the Master Servicer for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. The Master Servicer also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the Certificate Account, Distribution Account or any Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, or assert by legal action or otherwise any claim or right of setoff against any Mortgage File or any funds collected on, or in connection with, a Mortgage Loan, except, however, that the Master Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Master Servicer under this Agreement.

SECTION 3.14.

Servicing Compensation.

As compensation for its activities hereunder, the Master Servicer shall be entitled to retain or withdraw from the Certificate Account an amount equal to the Master Servicing Fee; provided, that the aggregate Master Servicing Fee with respect to any Distribution Date shall be reduced (i) by an amount equal to the aggregate of the Prepayment Interest Shortfalls on all of the Mortgage Loans, if any, with respect to such Distribution Date, but not to exceed the Compensating Interest for such Distribution Date, and (ii) with respect to the first Distribution Date, an amount equal to any amount to be deposited into the Distribution Account by the Depositor pursuant to Section 2.01(a) and not so deposited.

Additional servicing compensation in the form of Excess Proceeds, Prepayment Interest Excess, Prepayment Charges, assumption fees, late payment charges and all income and gain net of any losses realized from Permitted Investments on funds in the Certificate Account and Distribution Account shall be retained by the Master Servicer to the extent not required to be deposited in the Certificate Account pursuant to Section 3.05 hereof. The Master Servicer shall be required to pay all expenses incurred by it in connection with its master servicing activities hereunder (including payment of any premiums for hazard insurance and any Primary Insurance Policy and maintenance of the other forms of insurance coverage required by this Agreement) and shall not be entitled to reimbursement therefor except as specifically provided in this Agreement.

SECTION 3.15.

Access to Certain Documentation.

The Master Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders and/or Certificate Owners and the examiners and supervisory agents of the OTS, the FDIC and such other authorities, access to the documentation regarding the Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such access shall be afforded without charge, but only upon reasonable and prior written request and during normal business hours at the offices designated by the Master Servicer. Nothing in this Section shall limit the obligation of the Master Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors

III-15

and the failure of the Master Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section.

The Master Servicer acknowledges that as part of its servicing activities, the Master Servicer shall fully furnish, in accordance with the Fair Credit Reporting Act and its implementing regulations, accurate and complete information (i.e., favorable and unfavorable) on its borrower credit files related to the Mortgage Loans to Equifax, Experian and Trans Union Credit Information Company (three of the nationally recognized credit bureaus) on a monthly basis.

SECTION 3.16.

Annual Statement as to Compliance.

(a) The Master Servicer shall 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 the Master Servicer during the preceding calendar year (or applicable portion thereof) and of the performance of the Master Servicer 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 Master Servicer 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.

(b) The Master Servicer shall cause each Subservicer 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 Subservicer during the preceding calendar year (or applicable portion thereof) and of the performance of the Subservicer under the applicable Subservicing Agreement or primary servicing agreement, has been made under such officer’s supervision and (ii) to the best of such officer’s knowledge, based on such review, such Subservicer has fulfilled all its obligations under the applicable Subservicing Agreement or primary servicing 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.

SECTION 3.17.

Errors and Omissions Insurance; Fidelity Bonds.

The Master Servicer shall for so long as it acts as master servicer under this Agreement, obtain and maintain in force (a) a policy or policies of insurance covering errors and omissions in the performance of its obligations as Master Servicer hereunder and (b) a fidelity bond in respect of its officers, employees and agents. Each such policy or policies and bond shall, together, comply with the requirements from time to time of FNMA or FHLMC for persons performing servicing for mortgage loans purchased by FNMA or FHLMC. In the event that any such policy or bond ceases to be in effect, the Master Servicer shall obtain a comparable replacement policy or bond from an insurer or issuer, meeting the requirements set forth above as of the date of such replacement.

III-16

ARTICLE IV

DISTRIBUTIONS AND

ADVANCES BY THE MASTER SERVICER

SECTION 4.01.

Advances.

(a) The Master Servicer shall determine on or before each Master Servicer Advance Date whether it is required to make an Advance pursuant to the definition thereof. If the Master Servicer determines it is required to make an Advance, it shall, on or before the Master Servicer Advance Date, either (i) deposit into the Certificate Account an amount equal to the Advance or (ii) make an appropriate entry in its records relating to the Certificate Account that any Amount Held for Future Distribution has been used by the Master Servicer in discharge of its obligation to make any such Advance. Any funds so applied shall be replaced by the Master Servicer by deposit in the Certificate Account no later than the close of business on the next Master Servicer Advance Date. The Master Servicer shall be entitled to be reimbursed from the Certificate Account for all Advances of its own funds made pursuant to this Section as provided in Section 3.08. The obligation to make Advances with respect to any Mortgage Loan shall continue if such Mortgage Loan has been foreclosed or otherwise terminated and the related Mortgaged Property has not been liquidated.

(b) If the Master Servicer determines that it will be unable to comply with its obligation to make the Advances as and when described in the second sentence of Section 4.01(a), it shall use its best efforts to give written notice thereof to the Trustee (each such notice a “Trustee Advance Notice”; and such notice may be given by telecopy), not later than 3:00 P.M., New York time, on the Business Day immediately preceding the related Master Servicer Advance Date, specifying the amount that it will be unable to deposit (each such amount an “Advance Deficiency”) and certifying that such Advance Deficiency constitutes an Advance hereunder and is not a Nonrecoverable Advance. If the Trustee receives a Trustee Advance Notice on or before 3:30 P.M., New York time on a Master Servicer Advance Date, the Trustee shall, not later than 3:00 P.M., New York time, on the related Distribution Date, deposit in the Distribution Account an amount equal to the Advance Deficiency identified in such Trustee Advance Notice unless it is prohibited from so doing by applicable law. Notwithstanding the foregoing, the Trustee shall not be required to make such deposit if the Trustee shall have received written notification from the Master Servicer that the Master Servicer has deposited or caused to be deposited in the Certificate Account an amount equal to such Advance Deficiency. All Advances made by the Trustee pursuant to this Section 4.01(b) shall accrue interest on behalf of the Trustee at the Trustee Advance Rate from and including the date such Advances are made to but excluding the date of repayment, with such interest being an obligation of the Master Servicer and not the Trust Fund. The Master Servicer shall reimburse the Trustee for the amount of any Advance made by the Trustee pursuant to this Section 4.01(b) together with accrued interest, not later than the fifth day following the related Master Servicer Advance Date. In the event that the Master Servicer does not reimburse the Trustee in accordance with the requirements of the preceding sentence, the Trustee shall have the right, but not the obligation, to immediately (a) terminate all of the rights and obligations of the Master Servicer under this Agreement in accordance with Section 7.01 and (b) subject to the limitations set forth in Section 3.04, assume all of the rights and obligations of the Master Servicer hereunder.

(c) The Master Servicer shall, not later than the close of business on the second Business Day immediately preceding each Distribution Date, deliver to the Trustee a report (in form and substance reasonably satisfactory to the Trustee) that indicates (i) the Mortgage Loans with respect to which the Master Servicer has determined that the related Scheduled Payments should be advanced and (ii) the amount of the related Scheduled Payments. The Master Servicer shall deliver to the Trustee on

IV-1

the related Master Servicer Advance Date an Officer’s Certificate of a Servicing Officer indicating the amount of any proposed Advance determined by the Master Servicer to be a Nonrecoverable Advance.

SECTION 4.02.

Priorities of Distribution.

(a) On each Distribution Date, the Trustee shall withdraw the Available Funds from the Distribution Account and apply such funds to distributions on the Certificates in the following order, in each case, to the extent of Available Funds remaining:

(i) [Reserved];

(ii) concurrently, to each interest-bearing Class of Senior Certificates, an amount allocable to interest equal to the related Class Optimal Interest Distribution Amount, any shortfall being allocated among such Classes in proportion to the amount of the Class Optimal Interest Distribution Amount that would have been distributed in the absence of such shortfall, provided that prior to an Accrual Termination Date, the related Accrual Amount shall be distributed as provided in Section 4.02(a)(iii);

(iii) [Reserved];

(iv) to each Class of Senior Certificates, concurrently, as follows:

(x) to the Class PO Certificates, the PO Formula Principal Amount until its Class Certificate Balance is reduced to zero; and

(y) on each Distribution Date, the Non-PO Formula Principal Amount up to the amount of the Senior Principal Distribution Amount for such Distribution Date will be distributed in the following order:

(1) to the Class A-R Certificates, until its Class Certificate Balance is reduced to zero; and

(2) concurrently, to the Class X-0, Xxxxx X-0, Class A-3, Class A-5, Class A-6 and Class A-12 Certificates, pro rata, until their respective Class Certificate Balances are reduced to zero;

(v) to the Class PO Certificates, any Class PO Deferred Amount, up to an amount not to exceed the amount calculated pursuant to clause (A) of the definition of the Subordinated Principal Distribution Amount actually received or advanced for such Distribution Date (with such amount to be allocated first from amounts calculated pursuant to (A)(i) and (ii) then (iii) of the definition of Subordinated Principal Distribution Amount);

(vi) to each Class of Subordinated Certificates, subject to subparagraph (e) below, in the following order of priority:

(A) to the Class M Certificates, an amount allocable to interest equal to the Class Optimal Interest Distribution Amount for such Class for such Distribution Date;

(B) to the Class M Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof is reduced to zero;

IV-2

(C) to the Class B-1 Certificates, an amount allocable to interest equal to the Class Optimal Interest Distribution Amount for such Class for such Distribution Date;

(D) to the Class B-1 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof is reduced to zero;

(E) to the Class B-2 Certificates, an amount allocable to interest equal to the Class Optimal Interest Distribution Amount for such Class for such Distribution Date;

(F) to the Class B-2 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof is reduced to zero;

(G) to the Class B-3 Certificates, an amount allocable to interest equal to the amount of the Class Optimal Interest Distribution Amount for such Class for such Distribution Date;

(H) to the Class B-3 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof is reduced to zero;

(I) to the Class B-4 Certificates, an amount allocable to interest equal to the amount of the Class Optimal Interest Distribution Amount for such Class for such Distribution Date;

(J) to the Class B-4 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof is reduced to zero;

(K) to the Class B-5 Certificates, an amount allocable to interest equal to the Class Optimal Interest Distribution Amount for such Class for such Distribution Date;

(L) [Reserved]; and

(M) to the Class B-5 Certificates, an amount allocable to principal equal to its Pro Rata Share for such Distribution Date until the Class Certificate Balance thereof is reduced to zero;

(vii) [Reserved]; and

(viii) to the Class A-R Certificates, any remaining funds in the Trust Fund.

If any Class of Depositable Certificates has been surrendered to the Trustee for Exchangeable Certificates, the Trustee, as Holder of such surrendered Depositable Certificates, shall deposit any amounts distributable to such Class of Depositable Certificates in this Section 4.02(a) in the Exchangeable Certificates Distribution Account and shall distribute such amounts to the Holders of the related Class or Classes of Exchangeable Certificates pursuant to Section 5.07(b).

On any Distribution Date, amounts distributed in respect of Class PO Deferred Amounts will not reduce the Class Certificate Balance of the Class PO Certificates.

On any Distribution Date, to the extent the Amount Available for Senior Principal is insufficient to make the full distribution required to be made pursuant to subclause (iv)(x) above, (A) the amount distributable on the Class PO Certificates in respect of principal pursuant to such subclause (iv)(x) shall be equal to the product of (1) the Amount Available for Senior Principal and (2) a fraction, the numerator of which is the PO Formula Principal Amount and the denominator of which is the sum of the PO Formula Principal Amount and the Senior Principal Distribution Amount and (B) the amount distributable on the Senior Certificates, other than the Class PO Certificates, in respect of principal pursuant to clause (iv)(y) shall be equal to the product of (1) the Amount Available for Senior Principal and (2) a fraction, the numerator of which is the Senior Principal Distribution Amount and the denominator of which is the sum of the Senior Principal Distribution Amount and the PO Formula Principal Amount.

(b) On each Distribution Date prior to and including the applicable Accrual Termination Date with respect to each Class or Component of Accrual Certificates, the Accrual Amount for such Class or Component for such Distribution Date shall not (except as provided in the second to last sentence in this paragraph) be distributed as interest with respect to such Class or Component of Accrual Certificates, but shall instead be added to the related Class Certificate Balance or Component Balance of such Class or Component, as applicable, on the related Distribution Date. With respect to any Distribution Date prior to and including the applicable Accrual Termination Date on which principal payments on any Class or Component of Accrual Certificates are distributed pursuant to Section 4.02(a)(iv)(y), the related Accrual Amount shall be deemed to have been added on such Distribution Date to the related Class Certificate Balance or Component Balance (and included in the amount distributable on the related Class or Classes or Component of Accretion Directed Certificates pursuant to Section 4.02(a)(iii) for such Distribution Date) and the related distribution thereon shall be deemed to have been applied concurrently towards the reduction of all or a portion of the amount so added and, to the extent of any excess, towards the reduction of the Class Certificate Balance or Component Balance of such Class or Component of Accrual Certificates immediately prior to such Distribution Date. Notwithstanding any such distribution, each such Class or Component shall continue to be a Class of Accrual Certificates on each subsequent Distribution Date until the applicable Accrual Termination Date.

(d) On each Distribution Date, the amount referred to in clause (i) of the definition of Class Optimal Interest Distribution Amount for each Class of Certificates for such Distribution Date shall be reduced by (i) the related Class’ pro rata share of Net Prepayment Interest Shortfalls based on such Class’ Class Optimal Interest Distribution Amount for such Distribution Date, without taking into account such Net Prepayment Interest Shortfalls and (ii) the related Class’ Allocable Share of the interest portion of a Debt Service Reduction, and each Relief Act Reduction incurred during the calendar month preceding the month of such Distribution Date.

(e) Notwithstanding the priority and allocation contained in Section 4.02(a)(vi), if, on any Distribution Date, with respect to any Class of Subordinated Certificates (other than the Class of Subordinated Certificates then outstanding with the highest priority of distribution), the sum of the related Class Subordination Percentages of such Class and of all Classes of Subordinated Certificates which have a higher numerical Class designation than such Class (the “Applicable Credit Support Percentage”) is less than the Original Applicable Credit Support Percentage for such Class, no distribution of Principal Prepayments will be made to any such Classes (the “Restricted Classes”) and the amount of such Principal Prepayments otherwise distributable to the Restricted Classes shall be distributed to any Classes of Subordinated Certificates having lower numerical Class designations than such Class, pro rata, based on their respective Class Certificate Balances immediately prior to such Distribution Date and shall be distributed in the sequential order provided in Section 4.02(a)(vi).

IV-4

(f) [Reserved].

(g) If the amount of a Realized Loss on a Mortgage Loan has been reduced by application of Subsequent Recoveries with respect to such Mortgage Loan, an amount equal to the amount of such Subsequent Recoveries will be applied sequentially, in the order of payment priority, to increase the Class Certificate Balance of each Class of Certificates to which Realized Losses have been allocated, but in each case by not more than the amount of Realized Losses previously allocated to that Class of Certificates pursuant to Section 4.04. Holders of such Certificates will not be entitled to any payment in respect of the Class Optimal Interest Distribution Amount on the amount of such increases for any Interest Accrual Period preceding the Distribution Date on which such increase occurs. Any such increases shall be applied pro rata to the Certificate Balance of each Certificate of such Class.

SECTION 4.03.

[Reserved].

SECTION 4.04.

Allocation of Realized Losses.

(a) On or prior to each Determination Date, the Trustee shall determine the total amount of Realized Losses with respect to the related Distribution Date. For purposes of allocating losses to the Subordinated Certificates, the Class M Certificates will be deemed to have a lower numerical Class designation, and to be of a higher relative payment priority, than each other Class of Subordinated Certificates.

Realized Losses with respect to any Distribution Date shall be allocated as follows:

(i) the applicable PO Percentage of any Realized Loss shall be allocated to the Class PO Certificates until the Class Certificate Balance thereof is reduced to zero; and

(ii) the applicable Non-PO Percentage of any Realized Loss shall be allocated first to the Subordinated Certificates in reverse order of their respective numerical Class designations (beginning with the Class of Subordinated Certificates then outstanding with the highest numerical Class designation) until the respective Class Certificate Balance of each such Class is reduced to zero, and second, to the Classes of Senior Certificates (other than any Notional Amount Certificates and the Class PO Certificates), pro rata on the basis of their respective Class Certificate Balances immediately prior to such Distribution Date, or, in the case of any Class of Accrual Certificates or Accrual Component, on the basis of the lesser of their respective Class Certificate Balances or Component Balance, as applicable immediately prior to such Distribution Date, and their respective initial Class Certificate Balances or Component Balance, as applicable, until the respective Class Certificate Balance or Component Balance of each such Class or Component, is reduced to zero; provided, however, that the Non-PO Percentage of Realized Losses that would otherwise be allocated to the Class A-1, Class A-3 and Class A-5 Certificates will instead be allocated the Class A-2, Class A-12 and Class A-6 Certificates, respectively, until their respective Class Certificate Balances are reduced to zero.

(b) The Class Certificate Balance of Subordinated Certificates then outstanding with the highest numerical Class designation shall be reduced on each Distribution Date by the sum of (i) the amount of any payments on the Class PO Certificates in respect of Class PO Deferred Amounts and (ii) the amount, if any, by which the aggregate of the Class Certificate Balances of all outstanding Classes of Certificates (after giving effect to the distribution of principal and the allocation of Realized Losses and Class PO Deferred Amounts on such Distribution Date) exceeds the Pool Stated Principal Balance for the following Distribution Date.

IV-5

(c) Any Realized Losses allocated to a Class of Certificates or any reduction in the Class Certificate Balance of a Class of Certificates pursuant to Section 4.04(a) above shall be allocated among the Certificates of such Class in proportion to their respective Certificate Balances.

(d) Any allocation of Realized Losses to a Certificate or to any Component or any reduction in the Certificate Balance or Component Balance of a Certificate or Component, pursuant to Section 4.04(a) above shall be accomplished by reducing the Certificate Balance or Component Balance thereof, as applicable, immediately following the distributions made on the related Distribution Date in accordance with the definition of “Certificate Balance” or “Component Balance,” as the case may be. All Realized Losses allocated to a Class of Component Certificates will be allocated, pro rata, to the related Components.

SECTION 4.06.

Monthly Statements to Certificateholders.

(a) 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 U 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.

(b) The Trustee’s responsibility for disbursing the above information to the Certificateholders is limited to the availability, timeliness and accuracy of the information provided by the Master Servicer.

(c) On or before the fifth Business Day following the end of each Prepayment Period (but in no event later than the third Business Day prior to the related Distribution Date), the Master Servicer shall deliver to the Trustee (which delivery may be by electronic data transmission) a report in substantially the form set forth as Schedule VI hereto.

(d) Within a reasonable period of time after the end of each calendar year, the Trustee shall cause to be furnished to each Person who at any time during the calendar year was a Certificateholder, a statement containing the information set forth in items (1), (2) and (7) of Exhibit U hereto, aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder. Such obligation of the Trustee shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Trustee pursuant to any requirements of the Code as from time to time in effect.

SECTION 4.07.

Determination of Pass-Through Rates for COFI Certificates.

The Pass-Through Rate for each Class of COFI Certificates for each Interest Accrual Period after the initial Interest Accrual Period shall be determined by the Trustee as provided below on the basis of the Index and the applicable formulae appearing in footnotes corresponding to the COFI Certificates in the table relating to the Certificates in the Preliminary Statement.

IV-6

Except as provided below, with respect to each Interest Accrual Period following the initial Interest Accrual Period, the Trustee shall not later than two Business Days prior to such Interest Accrual Period but following the publication of the applicable Index determine the Pass-Through Rate at which interest shall accrue in respect of the COFI Certificates during the related Interest Accrual Period.

Except as provided below, the Index to be used in determining the respective Pass-Through Rates for the COFI Certificates for a particular Interest Accrual Period shall be COFI for the second calendar month preceding the Outside Reference Date for such Interest Accrual Period. If at the Outside Reference Date for any Interest Accrual Period, COFI for the second calendar month preceding such Outside Reference Date has not been published, the Trustee shall use COFI for the third calendar month preceding such Outside Reference Date. If COFI for neither the second nor third calendar months preceding any Outside Reference Date has been published on or before the related Outside Reference Date, the Index for such Interest Accrual Period and for all subsequent Interest Accrual Periods shall be the National Cost of Funds Index for the third calendar month preceding such Interest Accrual Period (or the fourth preceding calendar month if such National Cost of Funds Index for the third preceding calendar month has not been published by such Outside Reference Date). In the event that the National Cost of Funds Index for neither the third nor fourth calendar months preceding an Interest Accrual Period has been published on or before the related Outside Reference Date, then for such Interest Accrual Period and for each succeeding Interest Accrual Period, the Index shall be LIBOR, determined in the manner set forth below.

With respect to any Interest Accrual Period for which the applicable Index is LIBOR, LIBOR for such Interest Accrual Period will be established by the Trustee on the related Interest Determination Date as provided in Section 4.08.

In determining LIBOR and any Pass-Through Rate for the COFI Certificates 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 Reuters Screen) from the Reference Banks or the New York City banks as to LIBOR 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 Reference Banks or the New York City banks or to determine such arithmetic mean, all as provided for in this Section 4.07.

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

SECTION 4.08.

Determination of Pass-Through Rates for LIBOR Certificates.

(a) On each Interest Determination Date so long as any LIBOR Certificates are Outstanding or any Exchangeable Certificates with a Floating Pass-Through Rate have a Class Certificate Balance greater than zero, 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

IV-7

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 Master Servicer 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 Master Servicer 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 any such Certificate is Outstanding, on the basis of LIBOR and the respective formulae appearing in footnotes corresponding to the LIBOR Certificates in the table relating to the Certificates in the Preliminary Statement.

In determining LIBOR, any Pass-Through Rate for the LIBOR Certificates, any Interest Settlement Rate, or any Reserve Interest Rate, the Trustee may conclusively rely and shall be protected in relying upon the offered quotations (whether written, oral or on the Dow Xxxxx Markets) from the BBA

IV-8

designated banks, the Reference Banks or the New York City banks as to LIBOR, the Interest Settlement Rate or the Reserve Interest Rate, as appropriate, in effect from time to time. The Trustee shall not have any liability or responsibility to any Person for (i) the Trustee’s selection of New York City banks for purposes of determining any Reserve Interest Rate or (ii) its inability, following a good-faith reasonable effort, to obtain such quotations from, the BBA designated banks, the Reference Banks or the New York City banks or to determine such arithmetic mean, all as provided for in this Section 4.08.

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.

ARTICLE V

THE CERTIFICATES

SECTION 5.01.

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

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

SECTION 5.02.

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 5.06 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

V-1

Certificates are so surrendered for exchange, the Trustee shall execute, authenticate, and deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Trustee duly executed by the holder thereof or his attorney duly authorized in writing.

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

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

(b) No transfer of a Private Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under said Act and such state securities laws. In the event that a transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer and such Certificateholder’s prospective transferee shall each certify to the Trustee in writing the facts surrounding the transfer in substantially the forms set forth in Exhibit J-2 (the “Transferor Certificate”) and (i) deliver a letter in substantially the form of either Exhibit K (the “Investment Letter”) or Exhibit L-1 (the “Rule 144A Letter”) or (ii) there shall be delivered to the Trustee at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the Securities Act. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Certificate without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A. The Trustee and the Master Servicer shall cooperate with the Depositor in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Depositor shall reasonably request to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee and the Depositor, the Sellers and the Master Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of an ERISA-Restricted Certificate 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 Private Certificate, such requirement is satisfied only by the Trustee’s receipt of a representation letter from the transferee substantially in the form of Exhibit K or Exhibit L-1, or 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 I), 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, the Master Servicer or the Trust Fund, addressed to

V-2

the Trustee and the Master Servicer 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 or the Master Servicer 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, one 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 Certificate. 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 5.02(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trustee in accordance with the foregoing requirements.

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

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

(ii) 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 (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 I.

(iii) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee and to provide to the Trustee a certificate substantially in the form attached hereto as Exhibit J-1 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 5.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.02(c), then the last

V-3

preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 5.02(b) and this Section 5.02(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 after receipt of the related Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter, if required. The Trustee shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Permitted Transferee of such Certificate.

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

The restrictions on Transfers of a Residual Certificate set forth in this Section 5.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Master Servicer or any Seller, to the effect that the elimination of such restrictions will not cause any 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.

(d) The preparation and delivery of all certificates and opinions referred to above in this Section 5.02 in connection with transfer shall be at the expense of the parties to such transfers.

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

V-4

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 Event of Default, 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 the continuation of a book-entry system through the Depository is no longer in the best interests of the Certificate Owners, the Trustee shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of definitive, fully-registered Certificates (the “Definitive Certificates”) to Certificate Owners requesting the same. Upon surrender to the Trustee of the related Class of Certificates by the Depository, accompanied by the instructions from the Depository for registration, the Trustee shall issue the Definitive Certificates. Neither the Master Servicer, the Depositor nor the Trustee shall be liable for any delay in delivery of such instruction and each may conclusively rely on, and shall be protected in relying on, such instructions. The Master Servicer shall provide the Trustee with an adequate inventory of certificates to facilitate the issuance and transfer of Definitive Certificates. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Trustee, to the extent applicable with respect to such Definitive Certificates and the Trustee shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder; provided that the Trustee shall not by virtue of its assumption of such obligations become liable to any party for any act or failure to act of the Depository.

SECTION 5.03.

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 Master Servicer and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute, countersign and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like Class, tenor and Percentage Interest. In connection with the issuance of any new Certificate under this Section 5.03, 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 5.03 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 5.05.

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 or Master Servicer shall request such information in writing from the Trustee, then the Trustee shall, within ten Business Days after the receipt of such request, (x) provide the Depositor, the Master Servicer 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, and (y) assist the Depositor, the Master Servicer or such Certificateholders and/or Certificate Owners at such recipients’ expense with obtaining from the Depository a list of the related Depository Participants acting on behalf of Certificate Owners of Book Entry Certificates. The Depositor and every Certificateholder and 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 and/or Depository Participants hereunder, regardless of the source from which such information was derived.

SECTION 5.06.

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 5.07.

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

V-6

distributable to the surrendered Depositable Certificates pursuant to Section 4.02. 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 5.07(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 5.07(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 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. All distributions of principal to the Exchangeable Certificates shall be made pro rata among the Classes of Exchangeable Certificates within each Recombination Group unless specifically provided for otherwise in Schedule VII. 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.

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 5.07(b), such Class shall be allocated a proportionate share of the Net Prepayment Interest Shortfalls, the interest portion of Debt Service Reductions and Relief Act Reductions allocable to the Classes of Depositable Certificates in the related Recombination Group.

(d) On each Distribution Date on which a Class of Exchangeable Certificates shall be entitled to receive distributions pursuant to Section 5.07(b), such Class shall be allocated a proportionate share of the Realized Losses allocable to the Classes of Depositable Certificates in the related Recombination 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 Recombination Group in the respective Denominations determined based on the

V-7

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 VII, 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 VII. There shall be no limitation on the number of exchanges authorized pursuant to this Section 5.07.

Holders may exchange their Certificates according to this Section 5.07(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 and the initial Class Certificate Balance 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 5.07(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.

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 Master Servicer, the Master Servicer 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 Master Servicer.

As a condition to the effectiveness of any such resignation, at least 15 calendar days prior to the effective date of such resignation, the Master Servicer 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 Master Servicer.

DEFAULT

SECTION 7.01.

Events of Default.

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

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

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

(iii) a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 consecutive days; or

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

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

(vi) the Master Servicer shall fail to reimburse in full the Trustee within five days of the Master Servicer Advance Date for any Advance made by the Trustee pursuant to Section 4.01(b) together with accrued and unpaid interest.

If an Event of Default described in clauses (i) to (vi) of this Section shall occur, then, and in each and every such case, so long as such Event of Default shall not have been remedied, the Trustee may, or, if an Event of Default described in clauses (i) to (v) of this Section shall occur, then, and in each and every such case, so long as such Event of Default shall not have been remedied, at the direction of the

VII-1

Holders of Certificates evidencing not less than 66-2/3% of the Voting Rights evidenced by the Certificates, the Trustee shall, by notice in writing to the Master Servicer (with a copy to each Rating Agency and the Depositor), terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder.

In addition, if during the period that the Depositor is required to file Exchange Act Reports with respect to the Trust Fund, the Master Servicer shall fail to observe or perform any of the obligations that constitute a Limited Exchange Act Reporting Obligation or the obligations set forth in Section 3.16(a) or Section 11.07(a)(1) and (2), and such failure continues for the lesser of 10 calendar days or such period in which the applicable Exchange Act Report can be filed timely (without taking into account any extensions), so long as such failure shall not have been remedied, the Trustee shall, but only at the direction of the Depositor, terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder. The Depositor shall not be entitled to terminate the rights and obligations of the Master Servicer if a failure of the Master Servicer to identify a Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB was attributable solely to the role or functions of such Subcontractor with respect to mortgage loans other than the Mortgage Loans.

On and after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer hereunder, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee. The Trustee shall thereupon make any Advance which the Master Servicer failed to make subject to Section 4.01 hereof whether or not the obligations of the Master Servicer have been terminated pursuant to this Section. The Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise. Unless expressly provided in such written notice, no such termination shall affect any obligation of the Master Servicer to pay amounts owed pursuant to Article VIII. The Master Servicer agrees to cooperate with the Trustee in effecting the termination of the Master Servicer’s responsibilities and rights hereunder, including, without limitation, the transfer to the Trustee of all cash amounts which shall at the time be credited to the Certificate Account, or thereafter be received with respect to the Mortgage Loans.

Notwithstanding any termination of the activities of the Master Servicer hereunder, the Master Servicer shall be entitled to receive, out of any late collection of a Scheduled Payment on a Mortgage Loan which was due prior to the notice terminating such Master Servicer’s rights and obligations as Master Servicer hereunder and received after such notice, that portion thereof to which such Master Servicer would have been entitled pursuant to Sections 3.08(a)(i) through (viii), and any other amounts payable to such Master Servicer hereunder the entitlement to which arose prior to the termination of its activities hereunder.

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

VII-2

SECTION 7.02.

Trustee to Act; Appointment of Successor.

On and after the time the Master Servicer receives a notice of termination pursuant to Section 7.01 hereof, the Trustee shall, subject to and to the extent provided in Section 3.04, be the successor to the Master Servicer in its capacity as master servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof and applicable law including the obligation to make Advances pursuant to Section 4.01. As compensation therefor, the Trustee shall be entitled to all funds relating to the Mortgage Loans that the Master Servicer would have been entitled to charge to the Certificate Account or Distribution Account if the Master Servicer had continued to act hereunder. Notwithstanding the foregoing, if the Trustee has become the successor to the Master Servicer in accordance with Section 7.01 hereof, the Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to Section 4.01 hereof or if it is otherwise unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates, by each Rating Agency as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder. Any successor to the Master Servicer shall be an institution which is a FNMA and FHLMC approved seller/servicer in good standing, which has a net worth of at least $15,000,000, and which is willing to service the Mortgage Loans and (i) executes and delivers to the Depositor and the Trustee an agreement accepting such delegation and assignment, which contains an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Master Servicer (other than liabilities of the Master Servicer under Section 6.03 hereof incurred prior to termination of the Master Servicer under Section 7.01), with like effect as if originally named as a party to this Agreement; and provided further that each Rating Agency acknowledges that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced, as a result of such assignment and delegation and (ii) provides to the Depositor in writing fifteen days prior to the effective date of such appointment and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to a replacement master servicer. The Trustee shall provide written notice to the Depositor of such successor pursuant to this Section. Pending appointment of a successor to the Master Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so acting, shall, subject to Section 3.04 hereof, act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of the Master Servicing Fee permitted to be paid to the Master Servicer hereunder. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the Master Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

Any successor to the Master Servicer as master servicer shall give notice to the Mortgagors of such change of servicer and shall, during the term of its service as master servicer maintain in force the policy or policies that the Master Servicer is required to maintain pursuant to Section 3.09.

In connection with the termination or resignation of the Master Servicer hereunder, either (i) the successor Master Servicer, including the Trustee if the Trustee is acting as successor Master Servicer, shall represent and warrant that it is a member of MERS in good standing and shall agree to

VII-3

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

SECTION 7.03.

Notification to Certificateholders.

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

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

SECTION 8.05.

Trustee’s Fees and Expenses.

The Trustee, as compensation for its activities hereunder, shall be entitled to withdraw from the Distribution Account on each Distribution Date an amount equal to the Trustee Fee for such Distribution Date. The Trustee and any director, officer, employee or agent of the Trustee shall be indemnified by the Master Servicer and held harmless against any loss, liability or expense (including reasonable attorney’s fees) (i) incurred in connection with any claim or legal action relating to (a) this Agreement, (b) the Certificates or (c) in connection with the performance of any of the Trustee’s duties hereunder, other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of any of the Trustee’s duties hereunder or incurred by reason of any action of the Trustee taken at the direction of the Certificateholders and (ii) resulting from any error in any tax or information return prepared by the Master Servicer. Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Trustee hereunder. Without limiting the foregoing, the Master Servicer covenants and agrees, except as otherwise agreed upon in writing by the Depositor and the Trustee, and except for any such expense, disbursement or advance as may arise from the Trustee’s negligence, bad faith or willful misconduct, to pay or reimburse the Trustee, for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Agreement with respect to: (A) the reasonable compensation and the expenses and disbursements of its counsel not associated with the closing of the issuance of the Certificates, (B) the reasonable compensation, expenses and disbursements of any accountant, engineer or appraiser that is not regularly employed by the Trustee, to the extent that the Trustee must engage such persons to perform acts or services hereunder and (C) printing and engraving expenses in connection with preparing any Definitive Certificates.

If such corporation or association publishes reports of

VIII-3

condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.06 the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

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

SECTION 8.07.

Resignation and Removal of Trustee.

The Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice of resignation to the Depositor, the Master Servicer and each Rating Agency not less than 60 days before the date specified in such notice when, subject to Section 8.08, such resignation is to take effect, and acceptance by a successor trustee in accordance with Section 8.08 meeting the qualifications set forth in Section 8.06. 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.

If at any time (i) the Trustee shall cease to be eligible in accordance with the provisions of Section 8.06 hereof and shall fail to resign after written request thereto by the Depositor, (ii) the Trustee shall become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, (iii) a tax is imposed with respect to the Trust Fund by any state in which the Trustee or the Trust Fund is located and the imposition of such tax would be avoided by the appointment of a different trustee or (iv) during the period that the Depositor is required to file Exchange Act Reports with respect to the Trust Fund, the Trustee fails to comply with its obligations under the last sentence of Section 7.01, the preceding paragraph, Section 8.09 or Article XI and such failure is not remedied within the lesser of 10 calendar days or such period in which the applicable Exchange Act Report can be filed timely (without taking into account any extensions), then, in the case of clauses (i) through (iii), the Depositor or the Master Servicer, or in the case of clause (iv), the Depositor, may remove the Trustee and appoint a successor trustee by written instrument, in triplicate, one copy of which instrument shall be delivered to the Trustee, one copy of which shall be delivered to the Master Servicer and one copy 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 Master Servicer, one complete set to the Trustee so removed, one complete set to the successor so appointed and one complete set to the Depositor, 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 by the successor trustee.

VIII-4

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.07 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.08 hereof.

SECTION 8.08.

Successor Trustee.

Any successor trustee appointed as provided in Section 8.07 hereof shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee and the Master Servicer an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee herein. The Depositor, the Master Servicer and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties, and obligations.

No successor trustee shall accept appointment as provided in this Section 8.08 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 8.06 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 8.08, 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 8.09.

Merger or Consolidation of Trustee.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be eligible under the provisions of Section 8.06 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 8.10.

Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Master Servicer and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees jointly with the Trustee, or separate trustee or

VIII-5

separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust Fund or any part thereof, whichever is applicable, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider necessary or desirable. If the Master Servicer shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 8.08.

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

(i) To the extent necessary to effectuate the purposes of this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee, except for the obligation of the Trustee under this Agreement to advance funds on behalf of the Master Servicer, 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 Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the applicable Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

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

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

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

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

Any separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee

VIII-6

shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

SECTION 8.11.

Tax Matters.

It is intended that the assets with respect to which any REMIC election is to be made, as set forth in the Preliminary Statement, shall constitute, and that the conduct of matters relating to such assets shall be such as to qualify such assets as, a “real estate mortgage investment conduit” as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Trustee covenants and agrees that it shall act as agent (and the Trustee is hereby appointed to act as agent) on behalf of any such REMIC and that in such capacity it shall: (a) prepare and file, or cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return (Form 1066 or any successor form adopted by the Internal Revenue Service) and prepare and file or cause to be prepared and filed with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to any such REMIC, containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish or cause to be furnished to Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby; (b) within thirty days of the Closing Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the holders of the Certificates may contact for tax information relating thereto, together with such additional information as may be required by such Form, and update such information at the time or times in the manner required by the Code; (c) make or cause to be made elections that such assets be treated as a REMIC on the federal tax return for its first taxable year (and, if necessary, under applicable state law); (d) prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and to the Internal Revenue Service and, if necessary, state tax authorities, all information returns and reports as and when required to be provided to them in accordance with the REMIC Provisions, including without limitation, the calculation of any original issue discount using the Prepayment Assumption; (e) provide information necessary for the computation of tax imposed on the transfer of a Residual Certificate to a Person that is not a Permitted Transferee, or an agent (including a broker, nominee or other middleman) of a Non-Permitted Transferee, or a pass-through entity in which a Non-Permitted Transferee is the record holder of an interest (the reasonable cost of computing and furnishing such information may be charged to the Person liable for such tax); (f) to the extent that they are under its control conduct matters relating to such assets at all times that any Certificates are outstanding so as to maintain the status as a REMIC under the REMIC Provisions; (g) not knowingly or intentionally take any action or omit to take any action that would cause the termination of the tax status of any REMIC; (h) pay, from the sources specified in the third paragraph of this Section 8.11, the amount of any federal or state tax, including prohibited transaction taxes as described below, imposed on any such REMIC prior to its termination when and as the same shall be due and payable (but such obligation shall not prevent the Trustee or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Trustee from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings); (i) ensure that federal, state or local income tax or information returns shall be signed by the Trustee or such other person as may be required to sign such returns by the Code or state or local laws, regulations or rules; (j) maintain records relating to any such REMIC, including but not limited to the income, expenses, assets and liabilities thereof and the fair market value and adjusted basis of the assets determined at such intervals as may be required by the Code, as may be necessary to prepare the foregoing returns, schedules, statements or information; and (k) as and when necessary and appropriate, represent any such REMIC in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing authority, request an administrative adjustment as to any taxable year of any such REMIC, enter into settlement agreements with any governmental taxing agency, extend any

VIII-7

statute of limitations relating to any tax item of any such REMIC, and otherwise act on behalf of any such REMIC in relation to any tax matter or controversy involving it.

In order to enable the Trustee to perform its duties as set forth herein, the Depositor shall provide, or cause to be provided, to the Trustee within ten (10) days after the Closing Date all information or data that the Trustee requests in writing and determines to be relevant for tax purposes to the valuations and offering prices of the Certificates, including, without limitation, the price, yield, prepayment assumption and projected cash flows of the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide to the Trustee promptly upon written request therefor, any such additional information or data that the Trustee may, from time to time, reasonably request in order to enable the Trustee to perform its duties as set forth herein. The Depositor hereby indemnifies the Trustee for any losses, liabilities, damages, claims or expenses of the Trustee arising from any errors or miscalculations of the Trustee that result from any failure of the Depositor to provide, or to cause to be provided, accurate information or data to the Trustee on a timely basis.

In the event that any tax is imposed on “prohibited transactions” of any REMIC hereunder as defined in Section 860F(a)(2) of the Code, on the “net income from foreclosure property” of such REMIC as defined in Section 860G(c) of the Code, on any contribution to any REMIC hereunder after the Startup Day pursuant to Section 860G(d) of the Code, or any other tax is imposed, including, without limitation, any minimum tax imposed upon any REMIC hereunder pursuant to Sections 23153 and 24874 of the California Revenue and Taxation Code, if not paid as otherwise provided for herein, such tax shall be paid by (i) the Trustee, if any such other tax arises out of or results from a breach by the Trustee of any of its obligations under this Agreement, (ii) the Master Servicer, in the case of any such minimum tax, or if such tax arises out of or results from a breach by the Master Servicer or a Seller of any of their obligations under this Agreement, (iii) any Seller, if any such tax arises out of or results from that Seller’s obligation to repurchase a Mortgage Loan pursuant to Section 2.02 or 2.03 or (iv) in all other cases, or in the event that the Trustee, the Master Servicer or any Seller fails to honor its obligations under the preceding clauses (i),(ii) or (iii), any such tax will be paid with amounts otherwise to be distributed to the Certificateholders, as provided in Section 3.08(b).

SECTION 8.12.

Monitoring of Significance Percentage.

With respect to each Distribution Date, the Trustee shall calculate the “significance percentage” (as defined in Item 1115 of Regulation AB) of each derivative instrument, if any, based on the aggregate Class Certificate Balance of the related Classes of Covered Certificates for such derivative instrument and Distribution Date (after all distributions to be made thereon on such Distribution Date) and based on the methodology provided in writing by or on behalf of Countrywide no later than the fifth Business Day preceding such Distribution Date. On each Distribution Date, the Trustee shall provide to Countrywide a written report (which written report may include similar information with respect to other derivative instruments relating to securitization transactions sponsored by Countrywide) specifying the “significance percentage” of each derivative instrument, if any, for that Distribution Date. If the “significance percentage” of any derivative instrument exceeds 7.0% with respect to any Distribution Date, the Trustee shall make a separate notation thereof in the written report described in the preceding sentence. Such written report may contain such assumptions and disclaimers as are deemed necessary and appropriate by the Trustee.

SECTION 9.01.

Termination upon Liquidation or Purchase of all Mortgage Loans.

Subject to Section 9.03, the obligations and responsibilities of the Depositor, the Sellers, the Master Servicer and the Trustee created hereby with respect to the Trust Fund shall terminate upon the earlier of (a) the purchase by the Master Servicer of all Mortgage Loans (and REO Properties) remaining in the Trust Fund at the price equal to the sum of (i) 100% of the Stated Principal Balance of each Mortgage Loan plus one month’s accrued interest thereon at the applicable Adjusted Mortgage Rate, (ii) the lesser of (x) the appraised value of any REO Property as determined by the higher of two appraisals completed by two independent appraisers selected by the Master Servicer at the expense of the Master Servicer and (y) the Stated Principal Balance of each Mortgage Loan related to any REO Property and (iii) any remaining unpaid costs and damages incurred by the Trust Fund that arises out of a violation of any predatory or abusive lending law that also constitutes a breach of clause (49) on Schedule III-A, in all cases plus accrued and unpaid interest thereon at the applicable Adjusted Mortgage Rate and (b) the later of (i) the maturity or other liquidation (or any Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property and (ii) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement. In no event shall the trusts created hereby continue beyond the earlier of (i) the expiration of 21 years from the death of the survivor of the descendants of Xxxxxx X. Xxxxxxx, the late Ambassador of the United States to the Court of St. James’s, living on the date hereof and (ii) the Latest Possible Maturity Date.

The Master Servicer shall have the right to purchase all Mortgage Loans and REO Properties in the Trust Fund pursuant to clause (a) in the preceding paragraph of this Section 9.01 only on or after the date on which the Pool Stated Principal Balance, at the time of any such repurchase, is less than or equal to ten percent (10%) of the Cut-off Date Pool Principal Balance.

The ES Trust shall terminate automatically upon termination of the Trust Fund.

SECTION 9.02.

Final Distribution on the Certificates.

If on any Determination Date, the Master Servicer determines that there are no Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other than the funds in the Certificate Account, the Master Servicer shall direct the Trustee promptly to send a final distribution notice to each Certificateholder. If the Master Servicer elects to terminate the Trust Fund pursuant to clause (a) of Section 9.01, at least 20 days prior to the date notice is to be mailed to the affected Certificateholders, the Master Servicer shall notify the Depositor and the Trustee of the date the Master Servicer intends to terminate the Trust Fund and of the applicable repurchase price of the Mortgage Loans and REO Properties.

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

IX-1

In the event such notice is given, the Master Servicer shall cause all funds in the Certificate Account to be remitted to the Trustee for deposit in the Distribution Account on or before the Business Day prior to the applicable Distribution Date in an amount equal to the final distribution in respect of the Certificates. Upon such final deposit with respect to the Trust Fund and the receipt by the Trustee of a Request for Release therefor, the Trustee shall promptly release to the Master Servicer the Mortgage Files for the Mortgage Loans.

Upon presentation and surrender of the Certificates, the Trustee shall cause to be distributed to the Certificateholders of each Class, in each case on the final Distribution Date and in the order set forth in Section 4.02, and in proportion to their respective Percentage Interests, with respect to Certificateholders of the same Class, an amount equal to (i) as to each Class of Regular Certificates, the Certificate Balance thereof plus (a) accrued interest thereon (or on their Notional Amount, if applicable) in the case of an interest bearing Certificate and (b) any Class PO Deferred Amounts in the case of Class PO Certificates, and (ii) as to the Residual Certificates, the amount, if any, which remains on deposit in the Distribution Account (other than the amounts retained to meet claims) after application pursuant to clause (i) above. Notwithstanding the reduction of the Class Certificate Balance of any Class of Certificates to zero, such Class will be outstanding hereunder (solely for the purpose of receiving distributions and not for any other purpose) until the termination of the respective obligations and responsibilities of the Depositor, each Seller, the Master Servicer and the Trustee hereunder in accordance with Article IX.

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

SECTION 9.03.

Additional Termination Requirements.

(a) In the event the Master Servicer exercises its purchase option as provided in Section 9.01, the Trust Fund shall be terminated in accordance with the following additional requirements, unless the Trustee has been supplied with an Opinion of Counsel, at the expense of the Master Servicer, to the effect that the failure to comply with the requirements of this Section 9.03 will not (i) result in the imposition of taxes on “prohibited transactions” on any REMIC as defined in section 860F of the Code, or (ii) cause any REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(i) Within 90 days prior to the final Distribution Date set forth in the notice given by the Master Servicer under Section 9.02, the Master Servicer shall prepare and the Trustee, at the expense of the “tax matters person,” shall adopt a plan of complete liquidation within the meaning of section 860F(a)(4) of the Code which, as evidenced by an Opinion of Counsel (which opinion shall not be an expense of the Trustee or the Tax Matters Person), meets the requirements of a qualified liquidation; and

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, each Seller, the Depositor and the Master Servicer also may at any time and from time to time amend this Agreement without the consent of the Certificateholders to modify, eliminate or add to any of its provisions to such extent as shall be necessary or helpful to (i) maintain the qualification of any REMIC 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, each Seller, the Master Servicer and the Trustee with the consent of the Holders of a Majority in Interest of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) adversely affect in any material respect the interests of the Holders of any Class of Certificates in a manner other than as described in (i), without the consent of the Holders of Certificates of such Class evidencing, as to such Class, Percentage Interests aggregating 66-2/3%, 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.

X-1

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 10.01.

Governing Law.

THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

SECTION 10.04.

Intention of Parties.

(a) It is the express intent of the parties hereto that the conveyance of the (i) Mortgage Loans by the Sellers to the Depositor and (ii) Trust Fund by the Depositor to the Trustee each be, and be construed as, an absolute sale thereof to the Trustee. It is, further, not the intention of the

X-2

parties that such conveyances be deemed a pledge thereof. However, in the event that, notwithstanding the intent of the parties, such assets are held to be the property of any Seller or the Depositor, as the case may be, or if for any other reason this Agreement or any Supplemental Transfer Agreement is held or deemed to create a security interest in either such assets, then (i) this Agreement or any Supplemental Transfer Agreement shall be deemed to be a security agreement (within the meaning of the Uniform Commercial Code of the State of New York) with respect to all such assets and security interests and (ii) the conveyances provided for in this Agreement or any Supplemental Transfer Agreement shall be deemed to be an assignment and a grant pursuant to the terms of this Agreement (i) by each Seller to the Depositor or (ii) by the Depositor to the Trustee, for the benefit of the Certificateholders, of a security interest in all of the assets that constitute the Trust Fund, whether now owned or hereafter acquired.

Each Seller and the Depositor for the benefit of the Certificateholders shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Trust Fund, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement. The Depositor shall arrange for filing any Uniform Commercial Code continuation statements in connection with any security interest granted or assigned to the Trustee for the benefit of the Certificateholders.

(b) The Depositor hereby represents that:

(i) This Agreement creates a valid and continuing security interest (as defined in the Uniform Commercial Code as enacted in the State of New York (the “NY UCC”)) in the Mortgage Notes in favor of the Trustee, which security interest is prior to all other liens, and is enforceable as such as against creditors of and purchasers from the Depositor.

(ii) The Mortgage Notes constitutes “instruments” within the meaning of the NY UCC.

(iii) Immediately prior to the assignment of each Mortgage Loan to the Trustee, the Depositor owns and has good and marketable title to such Mortgage Loan free and clear of any lien, claim or encumbrance of any Person.

(iv) The Depositor has received all consents and approvals required by the terms of the Mortgage Loans to the sale of the Mortgage Loans hereunder to the Trustee.

(v) All original executed copies of each Mortgage Note that are required to be delivered to the Trustee pursuant to Section 2.01 have been delivered to the Trustee.

(vi) Other than the security interest granted to the Trustee pursuant to this Agreement, the Depositor has not pledged, assigned, sold, granted a security interest in, or otherwise conveyed any of the Mortgage Loans. The Depositor has not authorized the filing of and is not aware of any financing statements against the Depositor that include a description of collateral covering the Mortgage Loans other than any financing statement relating to the security interest granted to the Trustee hereunder or that has been terminated. The Depositor is not aware of any judgment or tax lien filings against the Depositor.

The parties to this Agreement shall not waive any of the representations set forth in this Section 10.04(b) without obtaining a confirmation of the then-current ratings of the Certificates.

(c) The Master Servicer shall take such action as is reasonably necessary to maintain the perfection and priority of the security interest of the Trustee in the Mortgage Loans; provided,

X-3

however, that the obligation to deliver the Mortgage File to the Trustee pursuant to Section 2.01 shall be solely the Depositor’s obligation and the Master Servicer shall not be responsible for the safekeeping of the Mortgage Files by the Trustee.

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

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of an Event of Default and of the continuance thereof, as herein provided, and unless the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates shall also have made written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require

The Master Servicer or the Trustee, as applicable, shall be responsible for obtaining from each Subcontractor and delivering to the Depositor and the Master Servicer, any assessment of compliance and attestation required to be delivered by such Subcontractor under Section 11.05 and Section 11.07, in each case as and when required to be delivered.

If, during the period that the Depositor is required to file Exchange Act Reports with respect to the Trust Fund, the Master Servicer is no longer an Affiliate of the Depositor, the Depositor shall assume the obligations and responsibilities of the Master Servicer in this Article XI with respect to the preparation and filing of the Exchange Act Reports and/or acting as the Certifying Person, if the Depositor has received indemnity from such successor Master Servicer satisfactory to the Depositor, and such Master Servicer has agreed to provide a Xxxxxxxx-Xxxxx Certification to the Depositor substantially in the form of Exhibit Y, and the certifications referred to in Section 11.07.

10) Each Mortgage Loan at origination complied in all material respects with applicable local, state and federal laws, including, without limitation, usury, equal credit opportunity, predatory and abusive lending laws, real estate settlement procedures, truth-in-lending and disclosure laws, and consummation of the transactions contemplated hereby will not involve the violation of any such laws.

11) As of the Closing Date, with respect to the Initial Mortgage Loans and as of the related Supplemental Transfer Date with respect to the Supplemental Mortgage Loans, neither the Sellers nor any prior holder of any Mortgage has modified the Mortgage in any material respect (except that a Mortgage Loan may have been modified by a written instrument which has been recorded or submitted for recordation, if necessary, to protect the interests of the Certificateholders and the original or a copy of which has been delivered to the Trustee); satisfied, cancelled or subordinated such Mortgage in whole or in part; released the related Mortgaged Property in whole or in part from the lien of such Mortgage; or executed any instrument of release, cancellation, modification or satisfaction with respect thereto.

12) A lender’s policy of title insurance together with a condominium endorsement and extended coverage endorsement, if applicable, in an amount at least equal to the Cut-off Date Stated Principal Balance of each such Mortgage Loan or a commitment (binder) to issue the same was effective on the date of the origination of each Mortgage Loan, each such policy is valid and remains in full force and effect, and each such policy was issued by a title insurer qualified to do business in the jurisdiction where the Mortgaged Property is located and acceptable to FNMA or FHLMC and is in a form acceptable to FNMA or FHLMC, which policy insures Countrywide and successor owners of indebtedness secured by the insured Mortgage, as to the first priority lien of the Mortgage subject to the exceptions set forth in paragraph (4) above; to the best of Countrywide’s knowledge, no claims have been made under such mortgage title insurance policy and no prior holder of the related Mortgage, including Countrywide, has done, by act or omission, anything which would impair the coverage of such mortgage title insurance policy.

13) Each Mortgage Loan was originated (within the meaning of Section 3(a)(41) of the Securities Exchange Act of 1934, as amended) by an entity that satisfied at the time of origination the requirements of Section 3(a)(41) of the Securities Exchange Act of 1934, as amended.

14) To the best of Countrywide’s knowledge, all of the improvements which were included for the purpose of determining the Appraised Value of the Mortgaged Property lie wholly within the boundaries and building restriction lines of such property, and no improvements on adjoining properties encroach upon the Mortgaged Property.

15) To the best of Countrywide’s knowledge, no improvement located on or being part of the Mortgaged Property is in violation of any applicable zoning law or regulation. To the best of Countrywide’s knowledge, all inspections, licenses and certificates required to be made or issued with respect to all occupied portions of the Mortgaged Property and, with respect to the use and occupancy of the same, including but not limited to certificates of occupancy and fire underwriting certificates, have been made or obtained from the appropriate authorities, unless the lack thereof would not have a material

S-III-A-2

adverse effect on the value of such Mortgaged Property, and the Mortgaged Property is lawfully occupied under applicable law.

16) Each Mortgage Note and the related Mortgage are genuine, and each is the legal, valid and binding obligation of the maker thereof, enforceable in accordance with its terms and under applicable law. To the best of Countrywide’s knowledge, all parties to the Mortgage Note and the Mortgage had legal capacity to execute the Mortgage Note and the Mortgage and each Mortgage Note and Mortgage have been duly and properly executed by such parties.

17) The proceeds of the Mortgage Loans have been fully disbursed, there is no requirement for future advances thereunder and any and all requirements as to completion of any on-site or off-site improvements and as to disbursements of any escrow funds therefor have been complied with. All costs, fees and expenses incurred in making, or closing or recording the Mortgage Loans were paid.

18) The related Mortgage contains customary and enforceable provisions which render the rights and remedies of the holder thereof adequate for the realization against the Mortgaged Property of the benefits of the security, including, (i) in the case of a Mortgage designated as a deed of trust, by trustee’s sale, and (ii) otherwise by judicial foreclosure.

19) With respect to each Mortgage constituting a deed of trust, a trustee, duly qualified under applicable law to serve as such, has been properly designated and currently so serves and is named in such Mortgage, and no fees or expenses are or will become payable by the Certificateholders to the trustee under the deed of trust, except in connection with a trustee’s sale after default by the Mortgagor.

20) Each Mortgage Note and each Mortgage is in substantially one of the forms acceptable to FNMA or FHLMC, with such riders as have been acceptable to FNMA or FHLMC, as the case may be.

21) There exist no deficiencies with respect to escrow deposits and payments, if such are required, for which customary arrangements for repayment thereof have not been made, and no escrow deposits or payments of other charges or payments due Countrywide have been capitalized under the Mortgage or the related Mortgage Note.

22) The origination, underwriting and collection practices used by Countrywide with respect to each Mortgage Loan have been in all respects legal, prudent and customary in the mortgage lending and servicing business.

23) There is no pledged account or other security other than real estate securing the Mortgagor’s obligations.

24) No Mortgage Loan has a shared appreciation feature, or other contingent interest feature.

25) Each Mortgage Loan contains a customary “due on sale” clause.

26) As of the Closing Date, 8.40% of the Initial Mortgage Loans by Cut-off Date Principal Balance provide for a prepayment charge.

27) Each Mortgage Loan which had a Loan-to-Value Ratio at origination in excess of 80.00% is the subject of a Primary Insurance Policy that insures that portion of the principal balance equal to a specified percentage times the sum of the remaining principal balance of the related Mortgage Loan, the accrued interest thereon and the related foreclosure expenses. The specified coverage percentage for mortgage loans with terms to maturity between 25 and 30 years is 12% for Loan-to-Value Ratios between

S-III-A-3

80.01% and 85.00%, 25% for Loan-to-Value Ratios between 85.01% and 90.00%, 30% for Loan-to-Value Ratios between 90.01% and 95.00% and 35% for Loan-to-Value Ratios between 95.01% and 100%. The specified coverage percentage for mortgage loans with terms to maturity of up to 20 years ranges from 6% to 12% for Loan-to-Value Ratios between 80.01% and 85.00%, from 12% to 20% for Loan-to-Value Ratios between 85.01% and 90.00% and 20% to 25% for Loan-to-Value Ratios between 90.01% and 95.00%. Each such Primary Insurance Policy is issued by a Qualified Insurer. All provisions of any such Primary Insurance Policy have been and are being complied with, any such policy is in full force and effect, and all premiums due thereunder have been paid. Any Mortgage subject to any such Primary Insurance Policy obligates either the Mortgagor or the mortgagee thereunder to maintain such insurance and to pay all premiums and charges in connection therewith, subject, in each case, to the provisions of Section 3.09(b) of the Pooling and Servicing Agreement. The Mortgage Rate for each Mortgage Loan is net of any such insurance premium.

28) As of the Closing Date or the related Supplemental Transfer Date, the improvements upon each Mortgaged Property are covered by a valid and existing hazard insurance policy with a generally acceptable carrier that provides for fire and extended coverage and coverage for such other hazards as are customary in the area where the Mortgaged Property is located in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements securing such Mortgage Loan or (ii) the greater of (a) the outstanding principal balance of the Mortgage Loan and (b) an amount such that the proceeds of such policy shall be sufficient to prevent the Mortgagor and/or the mortgagee from becoming a co-insurer. If the Mortgaged Property is a condominium unit, it is included under the coverage afforded by a blanket policy for the condominium unit. All such individual insurance policies and all flood policies referred to in item (29) below contain a standard mortgagee clause naming Countrywide or the original mortgagee, and its successors in interest, as mortgagee, and Countrywide has received no notice that any premiums due and payable thereon have not been paid; the Mortgage obligates the Mortgagor thereunder to maintain all such insurance including flood insurance at the Mortgagor’s cost and expense, and upon the Mortgagor’s failure to do so, authorizes the holder of the Mortgage to obtain and maintain such insurance at the Mortgagor’s cost and expense and to seek reimbursement therefor from the Mortgagor.

29) If the Mortgaged Property is in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards, a flood insurance policy in a form meeting the requirements of the current guidelines of the Flood Insurance Administration is in effect with respect to such Mortgaged Property with a generally acceptable carrier in an amount representing coverage not less than the least of (A) the original outstanding principal balance of the Mortgage Loan, (B) the minimum amount required to compensate for damage or loss on a replacement cost basis, or (C) the maximum amount of insurance that is available under the Flood Disaster Protection Act of 1973, as amended.

30) To the best of Countrywide’s knowledge, there is no proceeding occurring, pending or threatened for the total or partial condemnation of the Mortgaged Property.

31) There is no material monetary default existing under any Mortgage or the related Mortgage Note and, to the best of Countrywide’s knowledge, there is no material event which, with the passage of time or with notice and the expiration of any grace or cure period, would constitute a default, breach, violation or event of acceleration under the Mortgage or the related Mortgage Note; and Countrywide has not waived any default, breach, violation or event of acceleration.

32) Each Mortgaged Property is improved by a one- to four-family residential dwelling including condominium units and dwelling units in PUDs, which, to the best of Countrywide’s

S-III-A-4

knowledge, does not include cooperatives or mobile homes and does not constitute other than real property under state law.

33) Each Mortgage Loan is being master serviced by the Master Servicer.

34) Any future advances made prior to the Cut-off Date have been consolidated with the outstanding principal amount secured by the Mortgage, and the secured principal amount, as consolidated, bears a single interest rate and single repayment term reflected on the Mortgage Loan Schedule. The consolidated principal amount does not exceed the original principal amount of the Mortgage Loan. The Mortgage Note does not permit or obligate the Master Servicer to make future advances to the Mortgagor at the option of the Mortgagor.

35) All taxes, governmental assessments, insurance premiums, water, sewer and municipal charges, leasehold payments or ground rents which previously became due and owing have been paid, or an escrow of funds has been established in an amount sufficient to pay for every such item which remains unpaid and which has been assessed, but is not yet due and payable. Except for (A) payments in the nature of escrow payments, and (B) interest accruing from the date of the Mortgage Note or date of disbursement of the Mortgage proceeds, whichever is later, to the day which precedes by one month the Due Date of the first installment of principal and interest, including without limitation, taxes and insurance payments, the Master Servicer has not advanced funds, or induced, solicited or knowingly received any advance of funds by a party other than the Mortgagor, directly or indirectly, for the payment of any amount required by the Mortgage.

36) Each Mortgage Loan was underwritten in all material respects in accordance with Countrywide’s underwriting guidelines as set forth in the Prospectus Supplement.

37) Other than with respect to any Streamlined Documentation Mortgage Loan as to which the loan-to-value ratio of the related Original Mortgage Loan was less than 90% at the time of the origination of such Original Mortgage Loan, prior to the approval of the Mortgage Loan application, an appraisal of the related Mortgaged Property was obtained from a qualified appraiser, duly appointed by the originator, who had no interest, direct or indirect, in the Mortgaged Property or in any loan made on the security thereof, and whose compensation is not affected by the approval or disapproval of the Mortgage Loan; such appraisal is in a form acceptable to FNMA and FHLMC.

55) All of the Mortgage Loans were originated in compliance with all applicable laws, including, but not limited to, all applicable anti-predatory and abusive lending laws.

56) No Mortgage Loan is a High Cost Loan or Covered Loan, as applicable, and with respect to the foregoing, the terms “High Cost Loan” and “Covered Loan” have the meaning assigned to them in the then current Standard & Poor’s LEVELS® Version 6.0 Glossary Revised, Appendix E which is attached hereto as Exhibit Q (the “Glossary”) where (x) a “High Cost Loan” is each loan identified in the column “Category under applicable anti-predatory lending law” of the table entitled “Standard & Poor's High Cost Loan Categorization” in the Glossary as each such loan is defined in the applicable anti-predatory lending law of the State or jurisdiction specified in such table and (y) a “Covered Loan” is each loan identified in the column “Category under applicable anti-predatory lending law” of the table entitled “Standard & Poor’s Covered Loan Categorization” in the Glossary as each such loan is defined in the applicable anti-predatory lending law of the State or jurisdiction specified in such table.

S-III-A-7

60) The originator of each Mortgage Loan offered the related borrower mortgage loan products offered by such Mortgage Loan’s originator, or any affiliate of such Mortgage Loan’s originator, for which the borrower qualified.

61) The methodology used in underwriting the extension of credit for each Mortgage Loan employs objective mathematical principles which relate the borrower’s income, assets and liabilities to the proposed payment and such underwriting methodology does not rely on the extent of the borrower’s equity in the collateral as the principal determining factor in approving such credit extension.

62) No borrower under a Mortgage Loan was charged “points and fees” in an amount greater than (a) $1,000 or (b) 5% of the principal amount of such Mortgage Loan, whichever is greater. For purposes of this representation, “points and fees” (x) include origination, underwriting, broker and finder’s fees and charges that the lender imposed as a condition of making the Mortgage Loan, whether they are paid to the lender or a third party; and (y) exclude bona fide discount points, fees paid for actual services rendered in connection with the origination of the Mortgage Loan (such as attorneys’ fees, notaries fees and fees paid for property appraisals, credit reports, surveys, title examinations and extracts, flood and tax certifications, and home inspections); the cost of mortgage insurance or credit-risk price adjustments; the costs of title, hazard, and flood insurance policies; state and local transfer taxes or fees; escrow deposits for the future payment of taxes and insurance premiums; and other miscellaneous fees and charges that, in total, do not exceed 0.25 percent of the loan amount.

63) All points, fees and charges (including finance charges), whether or not financed, assessed, collected or to be collected in connection with the origination and servicing of each Mortgage Loan, have been disclosed in writing to the borrower in accordance with applicable state and federal law and regulation.

CWALT, INC.

Mortgage Pass-Through Certificates

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

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

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

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

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

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Trustee and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer and the

E-1

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

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

E-2

expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement.

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

Series 200_-_

STATE OF	)
	) ss:
COUNTY OF	)

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

1. The undersigned is an officer of , the proposed Transferee of an Ownership Interest in a Class A-R Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement, dated as of _________ __, 2___ (the “Agreement”), by and among CWALT, Inc., as depositor (the “Depositor”), Countrywide Home Loans, Inc. (the “Company”), as a Seller, Park Granada LLC, as a Seller, Park Monaco, Inc., as a Seller, Park Sienna LLC, as a Seller (and together with the Company, Park Granada and Park Monaco, the “Sellers”), Countrywide Home Loans Servicing LP, as Master Servicer and The Bank of New York, as Trustee. Capitalized terms used, but not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee.

2. The Transferee is not an employee benefit plan that is subject to Title I of ERISA or to section 4975 of the Internal Revenue Code of 1986, nor is it acting on behalf of or with plan assets of any such plan. 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

I-1

interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is a Permitted Transferee and the pass-through entity does not have actual knowledge that such affidavit is false. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.)

5. The Transferee has reviewed the provisions of Section 5.02(c) of the Agreement (attached hereto as Exhibit 2 and incorporated herein by reference) and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 5.02(c) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

6. The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and in connection with any Transfer by a Person for whom the Transferee is acting as nominee, trustee or agent, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a certificate substantially in the form set forth as Exhibit J-1 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 Class A-R Certificates.

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

I-2

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

12. 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

I-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.

EXHIBIT 2 to

EXHIBIT I

Section 5.02(c) of the Agreement

(c) Each Person who has or who acquires any Ownership Interest in a Class A-R 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 Class A-R Certificate are expressly subject to the following provisions:

(1) Each Person holding or acquiring any Ownership Interest in a Class A-R 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 Class A-R Certificate may be registered on the Closing Date or thereafter transferred, and the Trustee shall not register the Transfer of any Class A-R 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 I.

(3) Each Person holding or acquiring any Ownership Interest in a Class A-R 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 Class A-R 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 Class A-R Certificate and (C) not to Transfer its Ownership Interest in a Class A-R Certificate, or to cause the Transfer of an Ownership Interest in a Class A-R 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 Class A-R Certificate in violation of the provisions of this Section 5.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Class A-R Certificate in violation of the provisions of this Section 5.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Class A-R Certificate. The Trustee shall be under no liability to any Person for any registration of Transfer of a Class A-R Certificate that is in fact not permitted by Section 5.02(b) and this Section 5.02(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 after receipt of the related Transfer Affidavit and Transferor Certificate. The Trustee shall be entitled but not obligated to

I-8

recover from any Holder of a Class A-R 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 Class A-R 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 Class A-R Certificate to any Holder who is not a Permitted Transferee.

The restrictions on Transfers of a Class A-R Certificate set forth in this section 5.02(c) shall cease to apply (and the applicable portions of the legend on a Class A-R 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 Trustee, the Sellers or the Master Servicer, 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 Class A-R Certificate hereby consents to any amendment of this Agreement that, 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 Class A-R 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 Class A-R Certificate that is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.
