Y3 = the principal balance of the REMIC II Regular Interest LT3 after distributions on the prior Distribution Date.

Y4 = the principal balance of the REMIC II Regular Interest LT4 after distributions on the prior Distribution Date (note: Y3 = Y4).

ΔY1 = the REMIC II Regular Interest LT1 Principal Reduction Amount.

ΔY2 = the REMIC II Regular Interest LT2 Principal Reduction Amount.

ΔY3 = the REMIC II Regular Interest LT3 Principal Reduction Amount.

ΔY4 = the REMIC II Regular Interest LT4 Principal Reduction Amount.

P0 = the aggregate principal balance of the REMIC II Regular Interests LT1, LT2, LT3 and LT4 after distributions and the allocation of Realized Losses on the prior Distribution Date.

P1 = the aggregate principal balance of the REMIC II Regular Interests LT1, LT2, LT3 and LT4 after distributions and the allocation of Realized Losses to be made on such Distribution Date.

ΔP = P0 - P1 = the aggregate of the REMIC II Regular Interests LT1, LT2, LT3 and LT4 Principal Reduction Amounts.

=the aggregate of the principal portions of Realized Losses to be allocated to, and the principal distributions to be made on, the Group I Certificates on such Distribution Date (including distributions of accrued and unpaid interest on the Class SB-I Certificates for prior Distribution Dates).

R₀ = the Group I Net WAC Cap Rate (stated as a monthly rate) after giving effect to amounts distributed and Realized Losses allocated on the prior Distribution Date.

R₁ = the Group I Net WAC Cap Rate (stated as a monthly rate) after giving effect to amounts to be distributed and Realized Losses to be allocated on such Distribution Date.

ΔY3 = 0;

ΔY2 = α{γ1R0P0 - γ0R1P1}/{2R1R0P1 - γ1R0};

As of the Closing Date, the Uncertificated Principal Balance of each REMIC III Regular Interest shall equal the amount set forth in the Section 5.01(c)(iii) hereto as its Initial Uncertificated Principal Balance.

Date and, second, by all distributions of principal made on such Related Classes of Certificates on such Distribution Date. As of the Closing Date, the Uncertificated Principal Balance of each REMIC IV Regular Interest shall equal the amount set forth in the Section 5.01(c)(iv) hereto as its Initial Uncertificated Principal Balance. On each Distribution Date, the Uncertificated Principal Balance of each REMIC IV Regular Interest shall be reduced, first, by the portion of Realized Losses allocated in reduction of the Certificate Principal Balances of the Related Classes of Certificates on such Distribution Date and, second, by all distributions of principal made on such Related Classes of Certificates on such Distribution Date. As of the Closing Date, the Uncertificated Principal Balance of the REMIC V Regular Interest shall equal the amount set forth in Section 5.01(c)(v) as its Initial Uncertificated Principal Balance.

To the extent prescribed in regulations by the Secretary of the Treasury, which have not yet been issued, a trust which was in existence on August 20, 1996 (other than a trust treated as owned by the grantor under subpart E of part I of subchapter J of chapter 1 of the Code), and which was treated as a United States person on August 20, 1996 may elect to continue to be treated as a United States person notwithstanding the previous sentence.

Unpaid Realized Loss Amount: With respect to any Distribution Date and a Class of Group I Certificates, is the excess of (i) Applied Realized Loss Amounts with respect to such Class over (ii) the sum of all distributions in reduction of the Applied Realized Loss Amounts on all previous Distribution Dates.

Conveyance of Mortgage Loans;

Original Issuance of Certificates

Section 2.01. Conveyance of Mortgage Loans to Trustee. (a) The Depositor concurrently with the execution and delivery of this Agreement, sells, transfers and assigns to the Trust without recourse all its right, title and interest in and to (i) the Mortgage Loans identified in the Mortgage Loan Schedule, including all interest and principal due with respect to the Initial Mortgage Loans after the Cut-off Date and the Subsequent Mortgage Loans after the related Subsequent Cut-off Date, but excluding any payments of principal and interest due on or prior to the Cut-off Date; (ii) such assets as shall from time to time be credited or are required by the terms of this Agreement to be credited to the Distribution Account (iii) such assets relating to the Mortgage Loans as from time to time may be held by the Servicers in Protected Accounts and the Securities Administrator in the Distribution Account in the name of the Trustee on behalf of the Trust for the benefit of the Certificateholders and the Securities Administrator in the Cap Reserve Account in the name of the Trustee on behalf of the Trust for the benefit of the Group I Offered Certificateholders and the Class I-B-3 Certificateholders, (iv) any REO Property, (v) the Required Insurance Policies and any amounts paid or payable by the insurer under any Insurance Policy (to the extent the mortgagee has a claim thereto), (vi) the Mortgage Loan Purchase Agreement and the Subsequent Mortgage Loan Purchase Agreement to the extent provided in Section 2.03(a), (vii) the rights with respect to the Servicing Agreements (and each related Recognition Agreement as defined and described in the related Assignment Agreement) as assigned to the Trustee on behalf of the Trust for the benefit of the Certificateholders by the Assignment Agreements, (viii) such assets as shall from time to time be credited or are required by the terms of this Agreement to be credited to the Pre-Funding Account, the Interest Coverage Account, the Distribution Account and the Cap Reserve Account and (ix) any proceeds of the foregoing. Although it is the intent of the parties to this Agreement that the conveyance of the Depositor’s right, title and interest in and to the Mortgage Loans and other assets in the Trust Fund pursuant to this Agreement shall constitute a purchase and sale and not a loan, in the event that such conveyance is deemed to be a loan, it is the intent of the parties to this Agreement that the Depositor shall be deemed to have granted to the Trustee a first priority perfected security interest in all of the Depositor’s right, title and interest in, to and under the Mortgage Loans and other assets in the Trust Fund, and that this Agreement shall constitute a security agreement under applicable law.

(b) In connection with the above transfer and assignment, the Seller hereby deposits with the Trustee or the Custodian, as its agent, with respect to each Mortgage Loan:

(i) the original Mortgage Note, endorsed without recourse (A) to the order of the Trustee or (B) in the case of a Mortgage Loan registered on the MERS system, in blank, and in each case showing an unbroken chain of endorsements from the originator thereof to the Person endorsing it to the Trustee, or lost note affidavit together with a copy of the related Mortgage Note,

(ii) the original Mortgage and, if the related Mortgage Loan is a MOM Loan, noting the presence of the MIN and language indicating that such Mortgage Loan is a MOM Loan, which shall have been recorded (or if the original is not available, a copy), with evidence

of such recording indicated thereon (or if clause (w) in the proviso below applies, shall be in recordable form),

(iii) unless the Mortgage Loan is a MOM Loan, a certified copy of the assignment (which may be in the form of a blanket assignment if permitted in the jurisdiction in which the Mortgaged Property is located) to “JPMorgan Chase Bank, National Association, as Trustee”, with evidence of recording with respect to each Mortgage Loan in the name of the Trustee thereon (or if clause (w) in the proviso below applies or for Mortgage Loans with respect to which the related Mortgaged Property is located in a state other than Maryland, Tennessee, South Carolina, Mississippi and Florida, or an Opinion of Counsel has been provided as set forth in this Section 2.01(b), shall be in recordable form),

(iv) all intervening assignments of the Security Instrument, if applicable and only to the extent available to the Depositor with evidence of recording thereon,

(v) the original or a copy of the policy or certificate of primary mortgage guaranty insurance, to the extent available, if any,

(vi) the original policy of title insurance or mortgagee’s certificate of title insurance or commitment or binder for title insurance, and

(vii) originals of all modification agreements, if applicable and available.

provided, however, that in lieu of the foregoing, the Depositor may deliver the following documents, under the circumstances set forth below: (w) in lieu of the original Security Instrument, assignments to the Trustee or intervening assignments thereof which have been delivered, are being delivered or will, upon receipt of recording information relating to the Security Instrument required to be included thereon, be delivered to recording offices for recording and have not been returned to the Depositor in time to permit their delivery as specified above, the Depositor may deliver a true copy thereof with a certification by the Depositor, on the face of such copy, substantially as follows: “Certified to be a true and correct copy of the original, which has been transmitted for recording” (x) in lieu of the Security Instrument, assignment to the Trustee or intervening assignments thereof, if the applicable jurisdiction retains the originals of such documents (as evidenced by a certification from the Depositor to such effect) the Depositor may deliver photocopies of such documents containing an original certification by the judicial or other governmental authority of the jurisdiction where such documents were recorded; and (y) the Depositor shall not be required to deliver intervening assignments or Mortgage Note endorsements between the Seller and the Depositor, and between the Depositor and the Trustee; and provided, further, however, that in the case of Mortgage Loans which have been prepaid in full after the Cut-off Date and prior to the Closing Date, and in the case of Subsequent Mortgage Loans which have been prepaid in full after the related Subsequent Cut-off Date and prior to the related Subsequent Transfer Date, the Depositor, in lieu of delivering the above documents, may deliver to the Trustee or the Custodian, as its agent, a certification to such effect and shall deposit all amounts paid in respect of such Mortgage Loans in the Distribution Account on the Closing Date or the related Subsequent Transfer Date, as the case may be. The Depositor shall deliver such original documents (including any original documents as to which certified copies had previously been delivered) to the Trustee or the

Custodian, as its agent, promptly after they are received. The Depositor shall cause the Seller, at its expense, to cause each assignment of the Security Instrument to the Trustee to be recorded not later than 180 days after the Closing Date, unless (a) such recordation is not required by the Rating Agencies or an Opinion of Counsel addressed to the Trustee has been provided to the Trustee (with a copy to the Custodian) which states that recordation of such Security Instrument is not required to protect the interests of the Certificateholders in the related Mortgage Loans or (b) MERS is identified on the Mortgage or on a properly recorded assignment of the Mortgage as the mortgagee of record solely as nominee for the Seller and its successor and assigns; provided, however, that each assignment shall be submitted for recording by the Seller in the manner described above, at no expense to the Trust or the Trustee or the Custodian, as its agent, upon the earliest to occur of: (i) reasonable direction by the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust, (ii) the occurrence of an Event of Default, (iii) the occurrence of a bankruptcy, insolvency or foreclosure relating to the Seller and (iv) the occurrence of a servicing transfer as described in Section 8.02 hereof. Notwithstanding the foregoing, if the Seller fails to pay the cost of recording the assignments, such expense will be paid by the Trustee and the Trustee shall be reimbursed for such expenses by the Trust in accordance with Section 9.05.

Section 2.02. Acceptance of Mortgage Loans by Trustee. (a) The Trustee acknowledges the sale, transfer and assignment of the Trust Fund to it (or the Custodian, as its agent) by the Depositor and receipt of, subject to further review and the exceptions which may be noted pursuant to the procedures described below, and declares that it holds, the documents (or certified copies thereof) delivered to it or the Custodian, as its agent, pursuant to Section 2.01, and declares that it (or the Custodian, as its agent) will continue to hold those documents and any amendments, replacements or supplements thereto and all other assets of the Trust Fund delivered to it (or the Custodian, as its agent) as Trustee in trust for the use and benefit of all present and future Holders of the Certificates. On the Closing Date, with respect to the Initial Mortgage Loans, or the Subsequent Transfer Date, with respect to the Subsequent Mortgage Loans, the Custodian, with respect to the Mortgage Loans, shall acknowledge with respect to each Mortgage Loan by delivery to the Depositor and the Trustee of an Initial Certification receipt of the Mortgage File, but without review of such Mortgage File, except to the extent necessary to confirm that such Mortgage File contains the related Mortgage Note or lost note affidavit. No later than 90 days after the Closing Date (or within 90 days of the Subsequent Transfer Date, with respect to the Subsequent Mortgage Loans, or with respect to any Substitute Mortgage Loan, within five Business Days after the receipt by the Trustee or Custodian thereof), the Trustee agrees, for the benefit of the Certificateholders, to review or cause to be reviewed by the Custodian on its behalf (under the Custodial Agreement), each Mortgage File delivered to it and to execute and deliver, or cause to be executed and delivered, to the Depositor and the Trustee an Interim Certification. In conducting such review, the Trustee or Custodian will ascertain whether all required documents have been executed and received, and based on the Mortgage Loan Schedule, whether those documents relate, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans it has received, as identified in the Mortgage Loan Schedule. In performing any such review, the Trustee or the Custodian, as its agent, may conclusively rely on the purported due execution and genuineness of any such document and on the purported genuineness of any signature thereon. If the Trustee or the Custodian, as its agent, finds any document constituting part of the Mortgage File has not been executed or received, or to be unrelated, determined on the basis of the

Mortgagor name, original principal balance and loan number, to the Initial Mortgage Loans identified in Exhibit B, or the Subsequent Mortgage Loans identified on Exhibit 1 to the related Subsequent Transfer Instrument, as the case may be, or to appear defective on its face (a “Material Defect”), the Trustee or the Custodian, as its agent, shall promptly notify the Seller. In accordance with the Mortgage Loan Purchase Agreement or the Subsequent Mortgage Loan Purchase Agreement, the Seller shall correct or cure any such defect within ninety (90) days from the date of notice from the Trustee or the Custodian, as its agent, of the defect and if the Seller fails to correct or cure the defect within such period, and such defect materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan, the Trustee or the Custodian, as its agent, shall enforce the Seller’s obligation pursuant to the Mortgage Loan Purchase Agreement or the Subsequent Mortgage Loan Purchase Agreement, as the case may be, within 90 days from the Trustee’s or the Custodian’s notification, to purchase such Mortgage Loan at the Repurchase Price; provided that, if such defect would cause the Mortgage Loan to be other than a “qualified mortgage” as defined in Section 860G(a)(3)(A) of the Code and Treasury Regulation Section 1.860G-2(a)(1), (2), (4), (5), (6), (7) and (9), without reliance on the provisions of Treasury Regulation Section 1.860G-2(a)(3) or Treasury Regulation Section 1.860G-2(f)(2) or any other provision that would allow a Mortgage Loan to be treated as a “qualified mortgage” notwithstanding its failure to meet the requirements of Section 860G(a)(3)(A) of the Code and Treasury Regulation Section 1.860G-2(a)(1), (2), (4), (5), (6), (7) and (9), any such cure or repurchase must occur within 90 days from the date such breach was discovered; provided, however, that if such defect relates solely to the inability of the Seller to deliver the original Security Instrument or intervening assignments thereof, or a certified copy because the originals of such documents, or a certified copy have not been returned by the applicable jurisdiction, the Seller shall not be required to purchase such Mortgage Loan if the Seller delivers such original documents or certified copy promptly upon receipt, but in no event later than 360 days after the Closing Date or Subsequent Transfer Date, as applicable. The foregoing repurchase obligation shall not apply in the event that the Seller cannot deliver such original or copy of any document submitted for recording to the appropriate recording office in the applicable jurisdiction because such document has not been returned by such office; provided that the Seller shall instead deliver a recording receipt of such recording office or, if such receipt is not available, a certificate confirming that such documents have been accepted for recording, and delivery to the Trustee or the Custodian, as its agent, shall be effected by the Seller within thirty days of its receipt of the original recorded document.

(b) No later than 180 days after the Closing Date (or within 180 days of the Subsequent Transfer Date, with respect to the Subsequent Mortgage Loans, or with respect to any Substitute Mortgage Loan, within five Business Days after the receipt by the Trustee or the Custodian thereof), the Trustee or the Custodian, as its agent, will review, for the benefit of the Certificateholders, the Mortgage Files delivered to it and will execute and deliver or cause to be executed and delivered to the Depositor and the Trustee a Final Certification. In conducting such review, the Trustee or the Custodian, as its agent, will ascertain whether an original of each document required to be recorded has been returned from the recording office with evidence of recording thereon or a certified copy has been obtained from the recording office. If the Trustee or the Custodian, as its agent, finds a Material Defect, the Trustee or the Custodian, as its agent, shall promptly notify the Seller (provided, however, that with respect to those documents described in Sections 2.01(b)(iv), (v) and (vii), the Trustee’s and Custodian’s obligations shall extend only to the documents actually delivered to the Trustee or the Custodian pursuant to such

Sections). In accordance with the Mortgage Loan Purchase Agreement or the Subsequent Mortgage Loan Purchase Agreement, the Seller shall correct or cure any such defect within 90 days from the date of notice from the Trustee or the Custodian, as its agent, of the Material Defect and if the Seller is unable to cure such defect within such period, and if such defect materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan, the Trustee shall enforce the Seller’s obligation under the Mortgage Loan Purchase Agreement or the Subsequent Mortgage Loan Purchase Agreement, to provide a Substitute Mortgage Loan (if within two years of the Closing Date) or purchase such Mortgage Loan at the Repurchase Price; provided, however, that if such defect would cause the Mortgage Loan to be other than a “qualified mortgage” as defined in Section 860G(a)(3)(A) of the Code and Treasury Regulation Section 1.860G-2(a)(1), (2), (4), (5), (6), (7) and (9), without reliance on the provisions of Treasury Regulation Section 1.860G-2(a)(3) or Treasury Regulation Section 1.860G-2(f)(2) or any other provision that would allow a Mortgage Loan to be treated as a “qualified mortgage” notwithstanding its failure to meet the requirements of Section 860G(a)(3)(A) of the Code and Treasury Regulation Section 1.860G-2(a)(1), (2), (4), (5), (6), (7) and (9), any such cure, repurchase or substitution must occur within 90 days from the date such breach was discovered; provided, further, that if such defect relates solely to the inability of the Seller to deliver the original Security Instrument or intervening assignments thereof, or a certified copy, because the originals of such documents or a certified copy, have not been returned by the applicable jurisdiction, the Seller shall not be required to purchase such Mortgage Loan, if the Seller delivers such original documents or certified copy promptly upon receipt, but in no event later than 360 days after the Closing Date or Subsequent Transfer Date, as applicable. The foregoing repurchase obligation shall not apply in the event that the Seller cannot deliver such original or copy of any document submitted for recording to the appropriate recording office in the applicable jurisdiction because such document has not been returned by such office; provided that the Seller shall instead deliver a recording receipt of such recording office or, if such receipt is not available, a certificate confirming that such documents have been accepted for recording, and delivery to the Trustee or the Custodian, as its agent, shall be effected by the Seller within thirty days of its receipt of the original recorded document.

(c) In the event that a Mortgage Loan is purchased by the Seller in accordance with Sections 2.02(a) or (b) above, the Seller shall remit to the Master Servicer the Repurchase Price for deposit in the Distribution Account and the Seller shall provide to the Securities Administrator and the Trustee written notification detailing the components of the Repurchase Price. Upon deposit of the Repurchase Price in the Distribution Account, the Depositor shall notify the Trustee and the Custodian, as agent of the Trustee (upon receipt of a Request for Release in the form of Exhibit D attached hereto with respect to such Mortgage Loan), shall release to the Seller the related Mortgage File and the Trustee shall execute and deliver all instruments of transfer or assignment, without recourse, representation or warranty, furnished to it by the Seller, as are necessary to vest in the Seller title to and rights under the Mortgage Loan. Such purchase shall be deemed to have occurred on the date on which the Repurchase Price in available funds is received by the Securities Administrator. The Master Servicer shall amend the Mortgage Loan Schedule, which was previously delivered to it by the Depositor in a form agreed to between the Depositor and the Master Servicer, to reflect such repurchase and shall promptly notify the Trustee of such amendment and the Trustee shall promptly notify the Rating Agencies of such amendment. The obligation of the Seller to repurchase any Mortgage Loan as to which

such a defect in a constituent document exists shall be the sole remedy respecting such defect available to the Certificateholders or to the Trustee on their behalf.

Section 2.03. Assignment of Interest in the Mortgage Loan Purchase Agreement and Subsequent Mortgage Loan Purchase Agreement. (a) The Depositor hereby assigns to the Trustee, on behalf of the Certificateholders, all of its right, title and interest in the Mortgage Loan Purchase Agreement and Subsequent Mortgage Loan Purchase Agreement, including but not limited to the Depositor’s rights and obligations pursuant to the Servicing Agreements (noting that the Seller has retained the right in the event of breach of the representations, warranties and covenants, if any, with respect to the related Mortgage Loans of the related Servicer under the related Servicing Agreement to enforce the provisions thereof and to seek all or any available remedies). The obligations of the Seller to substitute or repurchase, as applicable, a Mortgage Loan shall be the Trustee’s and the Certificateholders’ sole remedy for any breach thereof. At the request of the Trustee, the Depositor shall take such actions as may be necessary to enforce the above right, title and interest on behalf of the Trustee and the Certificateholders or shall execute such further documents as the Trustee may reasonably require in order to enable the Trustee to carry out such enforcement.

(b) If the Depositor, the Master Servicer, or the Trustee discovers a breach of any of the representations and warranties set forth in the Mortgage Loan Purchase Agreement or the Subsequent Mortgage Loan Purchase Agreement, which breach materially and adversely affects the value of the interests of Certificateholders or the Trustee in the related Mortgage Loan, the party discovering the breach shall give prompt written notice of the breach to the other parties. The Seller, within 90 days of its discovery or receipt of notice that such breach has occurred (whichever occurs earlier), shall cure the breach in all material respects or, subject to the Mortgage Loan Purchase Agreement, Subsequent Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, shall purchase the Mortgage Loan or any property acquired with respect thereto from the Trustee; provided, however, that if there is a breach of any representation set forth in the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, and the Mortgage Loan or the related property acquired with respect thereto has been sold, then the Seller shall pay, in lieu of the Repurchase Price, any excess of the Repurchase Price over the Net Liquidation Proceeds received upon such sale. (If the Net Liquidation Proceeds exceed the Repurchase Price, any excess shall be paid to the Seller to the extent not required by law to be paid to the borrower.) Any such purchase by the Seller shall be made by providing an amount equal to the Repurchase Price to the Securities Administrator for deposit in the Distribution Account and written notification detailing the components of such Repurchase Price. The Depositor shall notify the Trustee and submit to the Trustee or the Custodian, as its agent, a Request for Release, and the Trustee shall release, or the Trustee shall cause the Custodian to release, to the Seller the related Mortgage File and the Trustee shall execute and deliver all instruments of transfer or assignment furnished to it by the Seller, without recourse, representation or warranty as are necessary to vest in the Seller title to and rights under the Mortgage Loan or any property acquired with respect thereto. Such purchase shall be deemed to have occurred on the date on which the Repurchase Price in available funds is received by the Securities Administrator. The Securities Administrator shall amend the Mortgage Loan Schedule to reflect such repurchase and shall promptly notify the Trustee and the Rating Agencies of such amendment. Enforcement of the obligation of the Seller to purchase (or substitute a Substitute Mortgage Loan for) any Mortgage Loan or any property acquired with

respect thereto (or pay the Repurchase Price as set forth in the above proviso) as to which a breach has occurred and is continuing shall constitute the sole remedy respecting such breach available to the Certificateholders or the Trustee on their behalf.

Section 2.04. Substitution of Mortgage Loans. Notwithstanding anything to the contrary in this Agreement, in lieu of purchasing a Mortgage Loan pursuant to the Mortgage Loan Purchase Agreement, Subsequent Mortgage Loan Purchase Agreement or Sections 2.02 or 2.03 of this Agreement, the Seller may, no later than the date by which such purchase by the Seller would otherwise be required, tender to the Trustee a Substitute Mortgage Loan accompanied by a certificate of an authorized officer of the Seller that such Substitute Mortgage Loan conforms to the requirements set forth in the definition of “Substitute Mortgage Loan” in the Mortgage Loan Purchase Agreement, Subsequent Mortgage Purchase Loan Agreement or this Agreement, as applicable; provided, however, that substitution pursuant to the Mortgage Loan Purchase Agreement, Subsequent Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, in lieu of purchase shall not be permitted after the termination of the two-year period beginning on the Startup Day; provided, further, that if the breach would cause the Mortgage Loan to be other than a “qualified mortgage” as defined in Section 860G(a)(3)(A) of the Code and Treasury Regulation Section 1.860G-2(a)(1), (2), (4), (5), (6), (7) and (9), without reliance on the provisions of Treasury Regulation Section 1.860G-2(a)(3) or Treasury Regulation Section 1.860G-2(f)(2) or any other provision that would allow a Mortgage Loan to be treated as a “qualified mortgage” notwithstanding its failure to meet the requirements of Section 860G(a)(3)(A) of the Code and Treasury Regulation Section 1.860G-2(a)(1), (2), (4), (5), (6), (7) and (9), any such cure or substitution must occur within 90 days from the date the breach was discovered. The Trustee will promptly notify the Master Servicer and the Securities Administrator of any such substitution. The Trustee or the Custodian, as its agent, shall examine the Mortgage File for any Substitute Mortgage Loan in the manner set forth in Section 2.02(a) and the Trustee or the Custodian, as its agent, shall notify the Seller, in writing, within five Business Days after receipt, whether or not the documents relating to the Substitute Mortgage Loan satisfy the requirements of the fourth sentence of Section 2.02(a). Within two Business Days after such notification, the Seller shall provide to the Securities Administrator for deposit in the Distribution Account the amount, if any, by which the Outstanding Principal Balance as of the next preceding Due Date of the Mortgage Loan for which substitution is being made, after giving effect to the Scheduled Principal due on such date, exceeds the Outstanding Principal Balance as of such date of the Substitute Mortgage Loan, after giving effect to Scheduled Principal due on such date, which amount shall be treated for the purposes of this Agreement as if it were the payment by the Seller of the Repurchase Price for the purchase of a Mortgage Loan by the Seller. After such notification to the Seller and, if any such excess exists, upon receipt of such deposit, the Trustee shall accept such Substitute Mortgage Loan which shall thereafter be deemed to be a Mortgage Loan hereunder. In the event of such a substitution, accrued interest on the Substitute Mortgage Loan for the month in which the substitution occurs and any Principal Prepayments made thereon during such month shall be the property of the Trust Fund and accrued interest for such month on the Mortgage Loan for which the substitution is made and any Principal Prepayments made thereon during such month shall be the property of the Seller. The Scheduled Principal on a Substitute Mortgage Loan due on the Due Date in the month of substitution shall be the property of the Seller and the Scheduled Principal on the Mortgage Loan for which the substitution is made due on such Due Date shall be the property of the Trust Fund. Upon acceptance of the Substitute Mortgage Loan (and delivery to the Trustee or the Custodian

as agent of the Trustee, as applicable, of a Request for Release for such Mortgage Loan), the Trustee or the Custodian, as agent for the Trustee, shall release to the Seller the related Mortgage File related to any Mortgage Loan released pursuant to the Mortgage Loan Purchase Agreement, the Subsequent Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, and shall execute and deliver all instruments of transfer or assignment, without recourse, representation or warranty in form as provided to it as are necessary to vest in the Seller title to and rights under any Mortgage Loan released pursuant to the Mortgage Loan Purchase Agreement , the Subsequent Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable. The Seller shall deliver the documents related to the Substitute Mortgage Loan in accordance with the provisions of the Mortgage Loan Purchase Agreement, Subsequent Mortgage Loan Purchase Agreement or Sections 2.01(b) and 2.02(b) of this Agreement, as applicable, with the date of acceptance of the Substitute Mortgage Loan deemed to be the Closing Date for purposes of the time periods set forth in those Sections. The representations and warranties set forth in the Mortgage Loan Purchase Agreement and the Subsequent Mortgage Loan Purchase Agreement shall be deemed to have been made by the Seller with respect to each Substitute Mortgage Loan as of the date of acceptance of such Mortgage Loan by the Trustee. The Master Servicer shall amend the Mortgage Loan Schedule to reflect such substitution and shall provide a copy of such amended Mortgage Loan Schedule to the Trustee and the Trustee shall deliver such amended Mortgage Loan Schedule to the Rating Agencies.

Section 2.05. Issuance of Certificates. (a) The Trustee acknowledges the assignment to it of the Mortgage Loans and the other assets comprising the Trust Fund and, concurrently therewith, has signed, and countersigned and delivered to the Depositor, in exchange therefor, Certificates in such authorized denominations representing such Fractional Undivided Interests as the Depositor has requested. The Trustee agrees that it will hold the Mortgage Loans and such other assets as may from time to time be delivered to it (or the Custodian, as its agent) segregated on the books of the Trustee in trust for the benefit of the Certificateholders.

(b) The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, assign, set over and otherwise convey in trust to the Trustee without recourse all the right, title and interest of the Depositor in and to (i) the REMIC I Regular Interests, and the other assets of REMIC III, for the benefit of the holders of the REMIC III Interests, (ii) the REMIC II Regular Interests and the REMIC III Regular Interests, and the other assets of REMIC IV, for the benefit of the holders of the REMIC IV Interests, and (iii) the REMIC IV Regular Interests B-IO-I and B-IO-P, and the other assets of REMIC V for the benefit of the holders of the REMIC V Interests. The Trustee acknowledges receipt of the REMIC I Regular Interests, REMIC II Regular Interests, REMIC III Regular Interests and REMIC IV Regular Interests B-IO-I and B-IO-P (each of which are uncertificated) and the other assets of REMIC III, REMIC IV and REMIC V, and declares that it holds and will hold the same in trust for the exclusive use and benefit of the holders of the REMIC III Interests, REMIC IV Interests and REMIC V Interests, as applicable.

Section 2.06. Representations and Warranties Concerning the Depositor. The Depositor hereby represents and warrants to the Trustee, the Master Servicer and the Securities Administrator as follows:

ARTICLE III

Administration and Servicing of Mortgage Loans

Section 3.01. Master Servicer. The Master Servicer shall supervise, monitor and oversee the obligation of the Servicers to service and administer their respective Mortgage Loans in accordance with the terms of the applicable Servicing Agreements and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices. Furthermore, the Master Servicer shall oversee and consult with each Servicer as necessary from time-to-time to carry out the Master Servicer’s obligations hereunder, shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by each Servicer and shall cause each Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by such Servicer under its applicable Servicing Agreement. The Master Servicer shall independently and separately monitor each Servicer’s servicing activities with respect to each related Mortgage Loan, reconcile the results of such monitoring with such information provided in the previous sentence on a monthly basis and coordinate corrective adjustments to the Servicers’ and Master Servicer’s records, and based on such reconciled and corrected information, the Master Servicer shall provide such information to the Securities Administrator as shall be necessary in order for it to prepare the statements specified in Section 6.04, and prepare any other information and statements required to be forwarded by the Master Servicer hereunder. The Master Servicer shall reconcile the results of its Mortgage Loan monitoring with the actual remittances of the Servicers as reported to the Master Servicer.

The Trustee shall furnish the Servicers and the Master Servicer with any powers of attorney, in substantially the form attached hereto as Exhibit O, and other documents in form as provided to it necessary or appropriate to enable the Servicers and the Master Servicer to service and administer the related Mortgage Loans and REO Property.

The Trustee shall provide access to the records and documentation in possession of the Trustee regarding the related Mortgage Loans and REO Property and the servicing thereof to the Certificateholders, the FDIC, and the supervisory agents and examiners of the FDIC, such access being afforded only upon reasonable prior written request and during normal business hours at the office of the Trustee; provided, however, that, unless otherwise required by law, the Trustee shall not be required to provide access to such records and documentation if the provision thereof would violate the legal right to privacy of any Mortgagor. The Trustee shall allow representatives of the above entities to photocopy any of the records and documentation and shall provide equipment for that purpose at a charge that covers the Trustee’s actual costs.

The Trustee shall execute and deliver to the Servicer and the Master Servicer any court pleadings, requests for trustee’s sale or other documents necessary or desirable to (i) the foreclosure or trustee’s sale with respect to a Mortgaged Property; (ii) any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Security Instrument; (iii) obtain a deficiency judgment against the Mortgagor; or (iv) enforce any other rights or remedies provided by the Mortgage Note or Security Instrument or otherwise available at law or equity.

Section 3.02. REMIC-Related Covenants. For as long as each 2006-1 REMIC shall exist, the Trustee and the Securities Administrator shall act in accordance herewith to assure continuing treatment of such 2006-1 REMIC as a REMIC, and the Trustee and the Securities Administrator shall comply with any directions of the Depositor, the related Servicer or the Master Servicer to assure such continuing treatment. In particular, the Trustee shall not (a) sell or permit the sale of all or any portion of the Mortgage Loans or of any investment of deposits in an Account unless such sale is as a result of a repurchase of the Mortgage Loans pursuant to this Agreement or the Trustee has received a REMIC Opinion addressed to the Trustee prepared at the expense of the Trust Fund; and (b) other than with respect to a substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, accept any contribution to any 2006-1 REMIC after the Startup Day without receipt of a REMIC Opinion addressed to the Trustee.

Section 3.03. Monitoring of Servicers. (a) The Master Servicer shall be responsible for reporting to the Trustee and the Depositor the compliance by each Servicer with its duties under the related Servicing Agreement. In the review of each Servicer’s activities, the Master Servicer may rely upon an officer’s certificate of the Servicer (or similar document signed by an officer of the Servicer) with regard to such Servicer’s compliance with the terms of its Servicing Agreement. In the event that the Master Servicer, in its judgment, determines that a Servicer should be terminated in accordance with its Servicing Agreement, or that a notice should be sent pursuant to such Servicing Agreement with respect to the occurrence of an event that, unless cured, would constitute grounds for such termination, the Master Servicer shall notify the Depositor and the Trustee thereof and the Master Servicer shall issue such notice or take such other action as it deems appropriate.

(b) The Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Servicer under the related Servicing Agreement, and shall, in the event that a Servicer fails to perform its obligations in accordance with the related Servicing Agreement, subject to the preceding paragraph, terminate the rights and obligations of such Servicer thereunder and act as successor servicer of the related Mortgage Loans or cause the Trustee to enter in to a new Servicing Agreement with a successor Servicer selected by the Master Servicer; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to such successor Servicer. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Servicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action.

(c) To the extent that the costs and expenses of the Master Servicer related to any termination of a Servicer, appointment of a successor Servicer or the transfer and assumption of servicing by the Master Servicer with respect to any Servicing Agreement (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the Servicer as a result of an event of default by

such Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including, but not limited to, all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor servicer to service the Mortgage Loans in accordance with the related Servicing Agreement) are not fully and timely reimbursed by the terminated Servicer, the Master Servicer shall be entitled to reimbursement of such costs and expenses from the Distribution Account.

(d) The Master Servicer shall require each Servicer to comply with the remittance requirements and other obligations set forth in the related Servicing Agreement, including the obligation of each Servicer to furnish information regarding the borrower credit files related to each Mortgage Loan to credit reporting agencies in compliance with the provisions of the Fair Credit Reporting Act and the applicable implementing regulations, on a monthly basis.

(e) If the Master Servicer acts as Servicer, it will not assume liability for the representations and warranties of the Servicer, if any, that it replaces.

Section 3.04. Fidelity Bond. The Master Servicer, at its expense, shall maintain in effect a blanket fidelity bond and an errors and omissions insurance policy, affording coverage with respect to all directors, officers, employees and other Persons acting on such Master Servicer’s behalf, and covering errors and omissions in the performance of the Master Servicer’s obligations hereunder. The errors and omissions insurance policy and the fidelity bond shall be in such form and amount generally acceptable for entities serving as master servicers or trustees.

Section 3.05. Power to Act; Procedures. The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article X hereof, to do any and all things that it may deem necessary or desirable in connection with the master servicing and administration of the Mortgage Loans, including but not limited to the power and authority (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, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, in each case, in accordance with the provisions of this Agreement and the Servicing Agreement, as applicable; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 3.03, shall not permit any Servicer to) knowingly or intentionally take any action, or fail to take (or fail to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, would cause any 2006-1 REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon the Trust Fund (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) unless the Master Servicer has received an Opinion of Counsel (but not at the expense of the Master Servicer) to the effect that the contemplated action would not cause any 2006-1 REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon any 2006-1 REMIC. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney

empowering the Master Servicer or any Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, to enable the Master Servicer to master service and administer the Mortgage Loans and carry out its duties hereunder, in each case in accordance with Accepted Master Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Master Servicer or any Servicer). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 9.11 hereof. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action in the name of the Trustee, be deemed to be the agent of the Trustee.

Section 3.06. Due-on-Sale Clauses; Assumption Agreements. To the extent provided in the applicable Servicing Agreement, to the extent Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer shall cause the Servicers to enforce such clauses in accordance with the applicable Servicing Agreement. If applicable law prohibits the enforcement of a due-on-sale clause or such clause is otherwise not enforced in accordance with the applicable Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the original Mortgagor may be released from liability in accordance with the applicable Servicing Agreement.

Section 3.07. Release of Mortgage Files. (a) Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by any Servicer of a notification that payment in full has been escrowed in a manner customary for such purposes for payment to Certificateholders on the next Distribution Date, the Servicer will, if required under the applicable Servicing Agreement (or if the Servicer does not, the Master Servicer may), promptly furnish to the Custodian, on behalf of the Trustee, two copies of a certification substantially in the form of Exhibit D hereto signed by a Servicing Officer or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer (which certification shall include a statement to the effect that all amounts received in connection with such payment that are required to be deposited in the Protected Account maintained by the applicable Servicer pursuant to Section 4.01, or by the applicable Servicer pursuant to its Servicing Agreement, have been or will be so deposited) and shall request that the Custodian, on behalf of the Trustee, deliver to the applicable Servicer the related Mortgage File. Upon receipt of such certification and request, the Custodian, on behalf of the Trustee, shall promptly release the related Mortgage File to the applicable Servicer and the Trustee and Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, each Servicer is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no

expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the Protected Account.

(b) From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan and in accordance with the applicable Servicing Agreement, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by a Servicer or the Master Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Custodian, on behalf of the Trustee, shall, upon the request of a Servicer or the Master Servicer, and delivery to the Custodian, on behalf of the Trustee, of two copies of a request for release signed by a Servicing Officer substantially in the form of Exhibit D (or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer), release the related Mortgage File held in its possession or control to the Servicer or the Master Servicer, as applicable. Such trust receipt shall obligate the Servicer or the Master Servicer to return the Mortgage File to the Custodian on behalf of the Trustee, when the need therefor by the Servicer or the Master Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that hereinabove specified, the Mortgage File shall be released by the Custodian, on behalf of the Trustee, to the Servicer or the Master Servicer.

Section 3.08. Documents, Records and Funds in Possession of Master Servicer To Be Held for Trustee. (a) The Master Servicer shall transmit and each Servicer (to the extent required by the related Servicing Agreement) shall transmit to the Trustee or Custodian such documents and instruments coming into the possession of the Master Servicer or such Servicer from time to time as are required by the terms hereof, or in the case of the Servicers, the applicable Servicing Agreement, to be delivered to the Trustee or Custodian. Any funds received by the Master Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer or by a Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit of the Trustee and the Certificateholders subject to the Master Servicer’s right to retain or withdraw from the Distribution Account the Master Servicing Compensation and other amounts provided in this Agreement, and to the right of each Servicer to retain its Servicing Fee and other amounts as provided in the applicable Servicing Agreement. The Master Servicer shall, and (to the extent provided in the applicable Servicing Agreement) shall cause each Servicer to, provide access to information and documentation regarding the Mortgage Loans to the Trustee, its agents and accountants at any time upon reasonable request and during normal business hours, and to Certificateholders that are savings and loan associations, banks or insurance companies, the Office of Thrift Supervision, the FDIC and the supervisory agents and examiners of such Office and Corporation or examiners of any other federal or state banking or insurance regulatory authority if so required by applicable regulations of the Office of Thrift Supervision or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during normal business hours at the offices of the Master Servicer designated by it. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

(b) 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 or Insurance Proceeds, shall be held by the

Master Servicer for and on behalf of the Trustee and the Certificateholders and shall be and remain the sole and exclusive property of the Trustee; provided, however, that the Master Servicer and each Servicer shall be entitled to setoff against, and deduct from, any such funds any amounts that are properly due and payable to the Master Servicer or such Servicer under this Agreement or the applicable Servicing Agreement.

Section 3.09. Standard Hazard Insurance and Flood Insurance Policies. (a) For each Mortgage Loan, the Master Servicer shall enforce any obligation of the Servicers under the related Servicing Agreements to maintain or cause to be maintained standard fire and casualty insurance and, where applicable, flood insurance, all in accordance with the provisions of the related Servicing Agreements. It is understood and agreed that such insurance shall be with insurers meeting the eligibility requirements set forth in the applicable Servicing Agreement and that no earthquake or other additional insurance is to be required of any Mortgagor or to be maintained on property acquired in respect of a defaulted loan, other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance.

(b) Pursuant to Section 4.01 and 4.04, any amounts collected by the Servicers or the Master Servicer, under any insurance policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or released to the Mortgagor in accordance with the applicable Servicing Agreement) shall be deposited into the Distribution Account, subject to withdrawal pursuant to Section 4.04 and 4.05. Any cost incurred by the Master Servicer or any Servicer in maintaining any such insurance if the Mortgagor defaults in its obligation to do so shall be added to the amount owing under the Mortgage Loan where the terms of the Mortgage Loan so permit; provided, however, that the addition of any such cost shall not be taken into account for purposes of calculating the distributions to be made to Certificateholders and shall be recoverable by the Master Servicer or such Servicer pursuant to Section 4.04 and 4.05.

Section 3.10. Presentment of Claims and Collection of Proceeds. The Master Servicer shall (to the extent provided in the applicable Servicing Agreement) cause the related Servicer to prepare and present on behalf of the Trustee and the Certificateholders all claims under the Insurance Policies and take such actions (including the negotiation, settlement, compromise or enforcement of the insured’s claim) as shall be necessary to realize recovery under such policies. Any proceeds disbursed to the Master Servicer (or disbursed to a Servicer and remitted to the Master Servicer) in respect of such policies, bonds or contracts shall be promptly deposited in the Distribution Account upon receipt, except that any amounts realized that are to be applied to the repair or restoration of the related Mortgaged Property as a condition precedent to the presentation of claims on the related Mortgage Loan to the insurer under any applicable Insurance Policy need not be so deposited (or remitted).

Section 3.11. Maintenance of the Primary Mortgage Insurance Policies. (a) The Master Servicer shall not take, or permit any Servicer (to the extent such action is prohibited under the applicable Servicing Agreement) to take, any action that would result in noncoverage under any applicable Primary Mortgage Insurance Policy of any loss which, but for the actions of the Master Servicer or such Servicer, would have been covered thereunder. The Master Servicer shall use its best reasonable efforts to cause each Servicer (to the extent required under the

related Servicing Agreement) to keep in force and effect (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance), primary mortgage insurance applicable to each Mortgage Loan in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable. The Master Servicer shall not, and shall not permit any Servicer (to the extent required under the related Servicing Agreement) to, cancel or refuse to renew any such Primary Mortgage Insurance Policy that is in effect at the date of the initial issuance of the Mortgage Note and is required to be kept in force hereunder except in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable.

(b) The Master Servicer agrees to present, or to cause each Servicer (to the extent required under the related Servicing Agreement) to present, on behalf of the Trustee and the Certificateholders, claims to the insurer under any Primary Mortgage Insurance Policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Primary Mortgage Insurance Policies respecting defaulted Mortgage Loans. Pursuant to Section 4.01 and 4.04, any amounts collected by the Master Servicer or any Servicer under any Primary Mortgage Insurance Policies shall be deposited in the Distribution Account, subject to withdrawal pursuant to Section 4.05.

Section 3.12. Trustee to Retain Possession of Certain Insurance Policies and Documents.

The Trustee (or the Custodian, as directed by the Trustee), shall retain possession and custody of the originals (to the extent available) of any Primary Mortgage Insurance Policies, or certificate of insurance if applicable, and any certificates of renewal as to the foregoing as may be issued from time to time as contemplated by this Agreement. Until all amounts distributable in respect of the Certificates have been distributed in full and the Master Servicer otherwise has fulfilled its obligations under this Agreement, the Trustee (or its Custodian, if any, as directed by the Trustee) shall also retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions of this Agreement. The Master Servicer shall promptly deliver or cause to be delivered to the Trustee (or the Custodian, as directed by the Trustee), upon the execution or receipt thereof the originals of any Primary Mortgage Insurance Policies, any certificates of renewal, and such other documents or instruments that constitute portions of the Mortgage File that come into the possession of the Master Servicer from time to time.

Section 3.13. Realization Upon Defaulted Mortgage Loans. The Master Servicer shall cause each Servicer (to the extent required under the related Servicing Agreement) to foreclose upon, repossess or otherwise comparably convert the ownership of Mortgaged 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, all in accordance with the applicable Servicing Agreement.

Section 3.14. Compensation for the Master Servicer.

The Master Servicer will be entitled to the income and gain realized from any investment of funds in the Distribution Account as set forth in Section 4.04 for the performance of its activities hereunder. Servicing compensation in the form of assumption fees, if any, late payment charges, as collected, if any, or otherwise (but not including any Prepayment Charge)

shall be retained by the applicable Servicer and shall not be deposited in the Protected Account. The Master Servicer will be entitled to retain, as additional compensation, any interest remitted by a Servicer in connection with a Principal Prepayment in full or otherwise in excess of amounts required to be remitted to the Distribution Account (such amounts together with the amounts specified in the first sentence of this Section 3.14, the “Master Servicing Compensation”). The Master Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor except as provided in this Agreement.

Section 3.15. REO Property.

The Master Servicer shall, to the extent provided in the applicable Servicing Agreement, cause the applicable Servicer to sell, any REO Property as expeditiously as possible and in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable. Pursuant to its efforts to sell such REO Property, the Master Servicer shall cause the applicable Servicer to protect and conserve, such REO Property in the manner and to the extent required by the applicable Servicing Agreement, in accordance with the REMIC Provisions and in a manner that does not result in a tax on “net income from foreclosure property” (unless such result would maximize the Trust Fund’s after-tax return on such property) or cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code.

(b) The Master Servicer shall, to the extent required by the related Servicing Agreement, cause the applicable Servicer to deposit all funds collected and received in connection with the operation of any REO Property in the Protected Account.

based on such review, the Master Servicer has fulfilled all of its obligations under this Agreement in all material respects throughout such year, 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 of cure provisions thereof.

Failure of the Master Servicer to comply with this Section 3.16 (including with respect to the time frames required in this Section) which failure results in a failure to timely file the Form 10-K, shall, be deemed an Event of Default, and the Trustee, at the direction of the Depositor shall, in addition to whatever rights the Trustee may have under this Agreement and at law or equity or to damages, including injunctive relief and specific performance, upon notice immediately terminate all the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Master Servicer for the same. This paragraph shall supercede any other provision in this Agreement or any other agreement to the contrary.

Section 3.17. Assessments of Compliance and Attestation Records. Pursuant to Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122 of Regulation AB, the Master Servicer and the Custodian (each, an “Attesting Party”) shall deliver to the Depositor, the Securities Administrator and the Trustee on or before March 1 (with a 10 calendar day cure period) of each calendar year beginning in 2007, a report regarding such Attesting Party's assessment of compliance (an “Assessment of Compliance”) with the Servicing Criteria during the preceding calendar year.

(c) An assessment by such officer of the related Attesting Party’s compliance with the applicable Servicing Criteria for the period consisting of the preceding calendar year, including disclosure of any material instance of noncompliance with respect thereto during such period, which assessment shall be based on the activities such Attesting Party performs with

respect to asset-backed securities transactions taken as a whole involving the related Attesting Party, that are backed by the same asset type as the Mortgage Loans;

(d) A statement that a registered public accounting firm has issued an attestation report on the related Attesting Party’s Assessment of Compliance for the period consisting of the preceding calendar year; and

(e) A statement as to which of the Servicing Criteria, if any, are not applicable to such related Attesting Party, which statement shall be based on the activities such related Attesting Party performs with respect to asset-backed securities transactions taken as a whole involving such related Attesting Party, that are backed by the same asset type as the Mortgage Loans.

Such report at a minimum shall address each of the Servicing Criteria specified on Exhibit K hereto that are indicated as applicable to the related Attesting Party.

On or before March 1st of each calendar year beginning in 2007, each Attesting Party shall furnish to the Master Servicer, the Depositor, the Securities Administrator and the Trustee a report (an “Attestation Report”) by a registered public accounting firm that attests to, and reports on, the Assessment of Compliance made by the related Attesting Party, as required by Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122(b) of Regulation AB, which Attestation Report must be made in accordance with standards for attestation reports issued or adopted by the Public Company Accounting Oversight Board.

The Master Servicer shall cause each Person Participating in the Servicing Function to deliver to the Master Servicer, the Depositor, the Securities Administrator and the Trustee an Assessment of Compliance and Attestation Report as and when provided above along with an indication of what Servicing Criteria are addressed in such assessment.

Such Assessment of Compliance, as to any subservicer, shall at a minimum address each of the Servicing Criteria specified on Exhibit K hereto that are indicated as applicable to any “primary servicer.” The Securities Administrator shall confirm that each of the Assessments of Compliance delivered to it, taken as a whole, address all of the Servicing Criteria and taken individually address the Servicing Criteria for each party as set forth on Exhibit M and notify the Depositor of any exceptions. Notwithstanding the foregoing, as to any subcontractor (as defined in the related Servicing Agreement), an Assessment of Compliance is not required to be delivered unless it is required as part of a Form 10-K with respect to the Trust Fund.

Failure of the Master Servicer to timely comply with this Section 3.17 (including with respect to the time frames required in this Section) shall be deemed an Event of Default, and the Trustee, at the direction of the Depositor, shall, in addition to whatever rights the Trustee may have under this Agreement and at law or equity or to damages, including injunctive relief and specific performance, upon notice immediately terminate all the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Master Servicer for the same. This paragraph shall supercede any other provision in this Agreement or any other agreement to the contrary.

The Custodian shall deliver to the Trustee, the Master Servicer, the Securities Administrator and the Depositor an Assessment of Compliance and Attestation Report, as and when provided above, which shall at a minimum address each of the Servicing Criteria specified on Exhibit M hereto which are indicated as applicable to a “custodian.” Notwithstanding the foregoing, as to any Custodian, an Assessment of Compliance is not required to be delivered unless it is required as part of a Form 10-K with respect to the Trust Fund.

Accounts

Section 4.01. Protected Accounts. (a) The Master Servicer shall enforce the obligation of each Servicer to establish and maintain a Protected Account in accordance with the applicable Servicing Agreement, with records to be kept with respect thereto on a Mortgage Loan by Mortgage Loan basis, into which accounts shall be deposited within 48 hours (or as of such other time specified in the related Servicing Agreement) of receipt, all collections of principal and interest on any Mortgage Loan and with respect to any REO Property received by a Servicer, including Principal Prepayments, Insurance Proceeds, Liquidation Proceeds and advances made from the Servicer’s own funds (less servicing compensation as permitted by the applicable Servicing Agreement in the case of any Servicer) and all other amounts to be deposited in the Protected Account. The Servicer is hereby authorized to make withdrawals from and deposits to the related Protected Account for purposes required or permitted by this Agreement. To the extent provided in the related Servicing Agreement, the Protected Account shall be held by a Designated Depository Institution and segregated on the books of such institution in the name of the Trustee for the benefit of Certificateholders.

(b) To the extent provided in the related Servicing Agreement, amounts on deposit in a Protected Account may be invested in Permitted Investments in the name of the Trustee for the benefit of Certificateholders and, except as provided in the preceding paragraph, not commingled with any other funds. Such Permitted Investments shall mature, or shall be subject to redemption or withdrawal, no later than the date on which such funds are required to be withdrawn for deposit in the Distribution Account, and shall be held until required for such deposit. The income earned from Permitted Investments made pursuant to this Section 4.01 shall be paid to the related Servicer under the applicable Servicing Agreement, and the risk of loss of moneys required to be distributed to the Certificateholders resulting from such investments shall be borne by and be the risk of the related Servicer. The related Servicer (to the extent provided in the Servicing Agreement) shall deposit the amount of any such loss in the Protected Account within two Business Days of receipt of notification of such loss but not later than the second Business Day prior to the Distribution Date on which the moneys so invested are required to be distributed to the Certificateholders.

(c) To the extent provided in the related Servicing Agreement and subject to this Article IV, on or before each Servicer Remittance Date, the related Servicer shall withdraw or shall cause to be withdrawn from its Protected Accounts and shall immediately deposit or cause to be deposited in the Distribution Account amounts representing the following collections and payments (other than with respect to principal of or interest on the Initial Mortgage Loans due on or before the Cut-off Date or principal of or interest on Subsequent Mortgage Loans due on or before the related Subsequent Cut-off Date) with respect to each Loan Group or Sub-Loan Group, as applicable:

(i) Scheduled Payments on the Mortgage Loans received or any related portion thereof advanced by such Servicer pursuant to its Servicing Agreement which were due during or before the related Due Period, net of the amount thereof comprising its Servicing Fee or any fees with respect to any lender-paid primary mortgage insurance policy;

(ii) Full Principal Prepayments and any Liquidation Proceeds received by such Servicer with respect to the Mortgage Loans in the related Prepayment Period (or, in the case of Subsequent Recoveries, during the related Due Period), with interest to the date of prepayment or liquidation, net of the amount thereof comprising its Servicing Fee;

(iii) Partial Principal Prepayments received by such Servicer for the Mortgage Loans in the related Prepayment Period; and

(iv) Any amount to be used as a Monthly Advance.

(d) Withdrawals may be made from an Account only to make remittances as provided in Section 4.01(c), 4.04 and 4.05; to reimburse the Master Servicer or a Servicer for Monthly Advances which have been recovered by subsequent collections from the related Mortgagor; to remove amounts deposited in error; to remove fees, charges or other such amounts deposited on a temporary basis; or to clear and terminate the account at the termination of this Agreement in accordance with Section 10.01. As provided in Sections 4.01(c) and 4.04(b) certain amounts otherwise due to the Servicers may be retained by them and need not be deposited in the Distribution Account.

(e) The Master Servicer shall not itself waive (or authorize a Servicer to waive, unless such Servicer is allowed to waive in accordance with the terms of the related Servicing Agreement) any Prepayment Charge that the Trust would otherwise be entitled to unless: (i) the enforceability thereof shall have been limited by bankruptcy, insolvency, moratorium, receivership and other similar laws relating to creditors’ rights generally, (ii) the enforcement thereof is illegal, or any local, state or federal agency has threatened legal action if the prepayment penalty is enforced, (iii) the mortgage debt has been accelerated in connection with a foreclosure or other involuntary payment or (iv) such waiver is standard and customary in servicing similar Mortgage Loans and relates to a default or a reasonably foreseeable default and would, in the reasonable judgment of the Master Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related Mortgage Loan. In no event will the Master Servicer itself waive a Prepayment Charge in connection with a refinancing of a Mortgage Loan that is not related to a default or a reasonably foreseeable default. If a Prepayment Charge is waived by the Master Servicer, but does not meet the standards described above, then the Master Servicer is required to pay the amount of such waived Prepayment Charge by depositing such amount into the Distribution Account by the immediately succeeding Distribution Account Deposit Date.

Section 4.02. [Reserved].

Section 4.03. [Reserved].

Section 4.04. Distribution Account. (a) The Securities Administrator shall establish and maintain in the name of the Trustee, for the benefit of the Certificateholders, the Distribution Account as a segregated trust account or accounts.

(c) All amounts deposited to the Distribution Account shall be held by the Securities Administrator in the name of the Trustee in trust for the benefit of the Certificateholders in accordance with the terms and provisions of this Agreement.

therein shall not be subject to, and shall be protected from, all claims, liens, and encumbrances of any creditors or depositors of the Securities Administrator or the Master Servicer (whether made directly, or indirectly through a liquidator or receiver of the Securities Administrator or the Master Servicer). The Distribution Account shall be an Eligible Account. The amount at any time credited to the Distribution Account shall be invested in the name of the Trustee, in such Permitted Investments selected by the Master Servicer. The Master Servicer shall select the Permitted Investments for the funds on deposit in the Distribution Account. All Permitted Investments shall mature or be subject to redemption or withdrawal on or before, and shall be held until, the next succeeding Distribution Date if the obligor for such Permitted Investment is the Securities Administrator or, if such obligor is any other Person, the Business Day preceding such Distribution Date, in the case of Permitted Investments for the benefit of the Master Servicer. With respect to the Distribution Account and the funds deposited therein, the Securities Administrator shall take such action as may be necessary to ensure that the Certificateholders shall be entitled to the priorities afforded to such a trust account (in addition to a claim against the estate of the Trustee) as provided by 12 U.S.C. § 92a(e), and applicable regulations pursuant thereto, if applicable, or any applicable comparable state statute applicable to state chartered banking corporations.

(f) Any and all investment earnings and losses on amounts on deposit in the Distribution Account shall be for the account of the Master Servicer. The Master Servicer from time to time shall be permitted to withdraw or receive distribution of any and all investment earnings from the Distribution Account on behalf of itself. The risk of loss of moneys required to be distributed to the Certificateholders resulting from such investments shall be borne by and be the risk of the Master Servicer based on the Permitted Investments on which such loss is incurred. The Master Servicer shall deposit the amount of any such loss in the Distribution Account within two Business Days of receipt of notification of such loss but not later than the Distribution Date on which the moneys so invested are required to be distributed to the Certificateholders.

Section 4.05. Permitted Withdrawals and Transfers from the Distribution Account.

(a) to reimburse the Master Servicer or any Servicer for any Monthly Advance of its own funds, the right of the Master Servicer or a Servicer to reimbursement pursuant to this subclause (i) being limited to amounts received on a particular Mortgage Loan (including, for this purpose, the Repurchase Price therefor, Insurance Proceeds and Liquidation Proceeds) which represent late payments or recoveries of the principal of or interest on such Mortgage Loan with respect to which such Monthly Advance was made;

(b) to reimburse the Master Servicer or any Servicer from Insurance Proceeds or Liquidation Proceeds relating to a particular Mortgage Loan for amounts expended by the Master Servicer or such Servicer in good faith in connection with the restoration of the related

(c) to reimburse the Master Servicer or any Servicer from Insurance Proceeds relating to a particular Mortgage Loan for insured expenses incurred with respect to such Mortgage Loan and to reimburse the Master Servicer or such Servicer from Liquidation Proceeds from a particular Mortgage Loan for Liquidation Expenses incurred with respect to such Mortgage Loan; provided that the Master Servicer shall not be entitled to reimbursement for Liquidation Expenses with respect to a Mortgage Loan to the extent that (i) any amounts with respect to such Mortgage Loan were paid as Excess Liquidation Proceeds pursuant to clause (xi) of this Section 4.05(a) to the Master Servicer; and (ii) such Liquidation Expenses were not included in the computation of such Excess Liquidation Proceeds;

(d) to pay the Master Servicer or any Servicer, as appropriate, from Liquidation Proceeds or Insurance Proceeds received in connection with the liquidation of any Mortgage Loan, the amount which the Master Servicer or such Servicer would have been entitled to receive under clause (ix) of this Section 4.05(a) as servicing compensation on account of each defaulted scheduled payment on such Mortgage Loan if paid in a timely manner by the related Mortgagor;

(e) to pay the Master Servicer or any Servicer from the Repurchase Price for any Mortgage Loan, the amount which the Master Servicer or such Servicer would have been entitled to receive under clause (ix) of this Section 4.05(a) as servicing compensation;

(f) to reimburse the Master Servicer or any Servicer for advances of funds (other than Monthly Advances) made with respect to the Mortgage Loans, and the right to reimbursement pursuant to this clause being limited to amounts received on the related Mortgage Loan (including, for this purpose, the Repurchase Price therefor, Insurance Proceeds and Liquidation Proceeds) which represent late recoveries of the payments for which such advances were made;

(g) to reimburse the Master Servicer or any Servicer for any Nonrecoverable Advance that has not been reimbursed pursuant to clauses (i) and (vi);

(h) to pay the Master Servicer as set forth in Section 3.14;

Reimbursements made pursuant to clauses (vii), (ix), (xi) and (xii) will be allocated between the Loan Groups or Sub-Loan Groups, as applicable, pro rata based on the aggregate Stated Principal Balances of the Mortgage Loans in each Loan Group or Sub-Loan Group, as applicable.

For federal income tax purposes, the Class B-IO Certificateholder shall be the beneficial owner of the Reserve Fund, subject to the power of the Securities Administrator to distribute amounts under Section 6.01(b) and the eighth and ninth clauses of Section 6.01(a) and shall report items of income, deduction, gain or loss arising therefrom. For federal income tax purposes, amounts distributed to Certificateholders pursuant to the eighth and ninth clauses of Section 6.01(a) will be treated as first distributed to the Class B-IO Certificates and then paid from the Class B-IO Certificateholders to the applicable holders of the Group I Certificates.

Any losses on such Permitted Investments shall not in any case be a liability of the Securities Administrator but an amount equal to such losses shall be given by the Class B-IO Certificateholder to the Securities Administrator out of the Class B-IO Certificateholders’ own funds immediately as realized, for deposit by the Securities Administrator into the Reserve Fund.

In addition, on the earlier of (x) the Business Day prior to the Distribution Date on which all the assets of the Trust Fund are repurchased as described in Section 10.01(a) and (y) the Business Day prior to the Distribution Date occurring in January 2012, the Securities Administrator shall withdraw the amount on deposit in the Class XP Reserve Account, deposit such amount into the Distribution Account and remit such amount to the Securities Administrator and provide written instruction to the Securities Administrator to pay such amount to the related Class XP Certificates in accordance with Section 6.01(c) and Section 6.02(e), as applicable, and following such withdrawal the Class XP Reserve Account shall be closed.

The Securities Administrator on behalf of the Trust shall be the nominal owner of the Cap Reserve Account. The Class B-IO Certificateholder shall be the beneficial owner of the Cap Reserve Account, subject to the power of the Securities Administrator to distribute amounts under Section 6.01.

Any losses on such investments shall be deposited in the Cap Reserve Account by the Class B-IO Certificateholder out of its own funds immediately as realized.

ARTICLE V

Certificates

Section 5.01. Certificates. (a) The Depository, the Depositor and the Securities Administrator have entered into a Depository Agreement dated as of the Closing Date (the “Depository Agreement”). Except for the Residual Certificates, the Private Certificates and the Individual Certificates and as provided in Section 5.01(b), the Certificates shall at all times remain registered in the name of the Depository or its nominee and at all times: (i) registration of such Certificates may not be transferred by the Securities Administrator except to a successor to the Depository; (ii) ownership and transfers of registration of such Certificates on the books of the Depository shall be governed by applicable rules established by the Depository; (iii) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants; (iv) the Securities Administrator shall deal with the Depository as representative of such Certificate Owners of the respective Class of Certificates for purposes of exercising the rights of Certificateholders under this Agreement, and requests and directions for and votes of such representative shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; and (v) the Trustee and the Securities Administrator may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants.

The Residual Certificates and the Private Certificates are initially Physical Certificates. If at any time the Holders of all of the Certificates of one or more such Classes request that the Securities Administrator cause such Class to become Global Certificates, the Securities Administrator and the Depositor will take such action as may be reasonably required to cause the Depository to accept such Class or Classes for trading if it may legally be so traded.

All transfers by Certificate Owners of such respective Classes of Book-Entry Certificates and any Global Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owners. 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.

(b) If (i)(A) the Depositor advises the Securities Administrator in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository and (B) the Depositor is unable to locate a qualified successor within 30 days or (ii) the Depositor at its option advises the Securities Administrator in writing that it elects to terminate the book-entry system through the Depository, the Securities Administrator shall request that the Depository notify all Certificate Owners of the occurrence of any such event and of the availability of definitive, fully registered Certificates to Certificate Owners requesting the same. Upon surrender to the Securities Administrator of the Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Securities Administrator shall issue the definitive Certificates.

In addition, if an Event of Default has occurred and is continuing, each Certificate Owner materially adversely affected thereby may at its option request a definitive Certificate evidencing such Certificate Owner’s interest in the related Class of Certificates. In order to make such

101

request, such Certificate Owner shall, subject to the rules and procedures of the Depository, provide the Depository or the related Depository Participant with directions for the Securities Administrator to exchange or cause the exchange of the Certificate Owner’s interest in such Class of Certificates for an equivalent interest in fully registered definitive form. Upon receipt by the Securities Administrator of instructions from the Depository directing the Securities Administrator to effect such exchange (such instructions to contain information regarding the Class of Certificates and the Certificate Principal Balance being exchanged, the Depository Participant account to be debited with the decrease, the registered holder of and delivery instructions for the definitive Certificate, and any other information reasonably required by the Securities Administrator), (i) the Securities Administrator shall instruct the Depository to reduce the related Depository Participant’s account by the aggregate Certificate Principal Balance of the definitive Certificate, (ii) the Securities Administrator shall execute and deliver, in accordance with the registration and delivery instructions provided by the Depository, a Definitive Certificate evidencing such Certificate Owner’s interest in such Class of Certificates and (iii) the Securities Administrator shall execute a new Book-Entry Certificate reflecting the reduction in the aggregate Certificate Principal Balance of such Class of Certificates by the amount of the definitive Certificates.

Neither the Depositor nor the Securities Administrator shall be liable for any delay in the delivery of any instructions required pursuant to this Section 5.01(b) and may conclusively rely on, and shall be protected in relying on, such instructions.

(c) (i) As provided herein, the REMIC Administrator will make an election to treat the segregated pool of assets consisting of the Group II Mortgage Loans and certain other related assets subject to this Agreement as a REMIC for federal income tax purposes, and such segregated pool of assets will be designated as “REMIC I.” Component I of the Class R Certificates will represent the sole Class of “residual interests” in REMIC I for purposes of the REMIC Provisions (as defined herein) under federal income tax law. The following table irrevocably sets forth the designation, Uncertificated Pass-Through Rate and initial Uncertificated Principal Balance for each of the “regular interests” in REMIC I and the designation and Certificate Principal Balance of the Class R Certificates allocable to Component I of the Class R Certificates. None of the REMIC I Regular Interests will be certificated.

The Class R Certificates shall each be issued in certificated fully-registered form in the denomination of $100. The Class R-X Certificates shall each be issued in certificated fully-registered form with no denomination. Each Class of Global Certificates, if any, shall be issued in fully registered form in minimum dollar denominations of $100,000 and integral multiples of $1.00 in excess thereof, except that one Certificate of each Class may be in a different denomination so that the sum of the denominations of all outstanding Certificates of such Class shall equal the Certificate Principal Balance of such Class on the Closing Date. On the Closing Date, the Securities Administrator shall execute and countersign (i) in the case of each Class of Offered Certificates, the Certificate in the entire Certificate Principal Balance of the respective Class and (ii) in the case of each Class of Private Certificates, Individual Certificates all in an aggregate principal amount that shall equal the Certificate Principal Balance of each such respective Class on the Closing Date.

The Securities Administrator shall sign the Certificates by facsimile or manual signature and countersign them by manual signature on behalf of the Securities Administrator by one or more authorized signatories, each of whom shall be Responsible Officers of the Securities Administrator or its agent. A Certificate bearing the manual and facsimile signatures of individuals who were the authorized signatories of the Securities Administrator or its agent at the time of issuance shall bind the Securities Administrator, notwithstanding that such individuals or any of them have ceased to hold such positions prior to the delivery of such Certificate.

(h) No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate the manually executed countersignature of the Securities Administrator or its agent, 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 issued on the Closing Date shall be dated the Closing Date. All Certificates issued thereafter shall be dated the date of their countersignature.

(i) The Closing Date is hereby designated as the “startup” day of each 2006-1 REMIC within the meaning of Section 860G(a)(9) of the Code.

(j) For federal income tax purposes, each 2006-1 REMIC shall have a tax year that is a calendar year and shall report income on an accrual basis.

108

(k) The Trustee on behalf of the Trust shall cause each 2006-1 REMIC to timely elect to be treated as a REMIC under Section 860D of the Code.

Section 5.02. Registration of Transfer and Exchange of Certificates. (a) The Securities Administrator shall maintain at its Corporate Trust Office a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Securities Administrator shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided.

(c) By acceptance of a Private Certificate or a Residual Certificate, whether upon original issuance or subsequent transfer, each holder of such Certificate acknowledges the restrictions on the transfer of such Certificate set forth in the Securities Legend and agrees that it will transfer such a Certificate only as provided herein. In addition to the provisions of Section 5.02(h), the following restrictions shall apply with respect to the transfer and registration of transfer of an Private Certificate or a Residual Certificate to a transferee that takes delivery in the form of an Individual Certificate:

(i) The Securities Administrator shall register the transfer of an Individual Certificate if the requested transfer is being made to a transferee who has provided the Securities Administrator with a Rule 144A Certificate or comparable evidence as to its QIB status.

(ii) The Securities Administrator shall register the transfer of any Individual Certificate if (x) the transferor has advised the Securities Administrator in writing that the Certificate is being transferred to an Institutional Accredited Investor along with facts surrounding the transfer as set forth in Exhibit F-3 hereto; and (y) prior to the transfer the transferee furnishes to the Securities Administrator an Investment Letter (and the Securities Administrator shall be fully protected in so doing), provided that, if based upon an Opinion of Counsel addressed to the Securities Administrator to the effect that the delivery of (x) and (y) above are not sufficient to confirm that the proposed transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable laws, the Securities Administrator shall as a condition of the registration of any such transfer require the transferor to furnish such other certifications, legal opinions or other information prior to registering the transfer of an Individual Certificate as shall be set forth in such Opinion of Counsel.

(d) So long as a Global Certificate of such Class is outstanding and is held by or on behalf of the Depository, transfers of beneficial interests in such Global Certificate, or transfers by holders of Individual Certificates of such Class to transferees that take delivery in the form of beneficial interests in the Global Certificate, may be made only in accordance with Section 5.02(h), the rules of the Depository and the following:

110

(i) In the case of a beneficial interest in the Global Certificate being transferred to an Institutional Accredited Investor, such transferee shall be required to take delivery in the form of an Individual Certificate or Certificates and the Securities Administrator shall register such transfer only upon compliance with the provisions of Section 5.02(c)(ii).

(ii) In the case of a beneficial interest in a Class of Global Certificates being transferred to a transferee that takes delivery in the form of an Individual Certificate or Certificates of such Class, except as set forth in clause (i) above, the Securities Administrator shall register such transfer only upon compliance with the provisions of Section 5.02(c)(i).

(iii) In the case of an Individual Certificate of a Class being transferred to a transferee that takes delivery in the form of a beneficial interest in a Global Certificate of such Class, the Securities Administrator shall register such transfer if the transferee has provided the Securities Administrator with a Rule 144A Certificate or comparable evidence as to its QIB status.

(iv) No restrictions shall apply with respect to the transfer or registration of transfer of a beneficial interest in the Global Certificate of a Class to a transferee that takes delivery in the form of a beneficial interest in the Global Certificate of such Class; provided that each such transferee shall be deemed to have made such representations and warranties contained in the Rule 144A Certificate as are sufficient to establish that it is a QIB.

(e) Subject to Section 5.02(h), an exchange of a beneficial interest in a Global Certificate of a Class for an Individual Certificate or Certificates of such Class, an exchange of an Individual Certificate or Certificates of a Class for a beneficial interest in the Global Certificate of such Class and an exchange of an Individual Certificate or Certificates of a Class for another Individual Certificate or Certificates of such Class (in each case, whether or not such exchange is made in anticipation of subsequent transfer, and, in the case of the Global Certificate of such Class, so long as such Certificate is outstanding and is held by or on behalf of the Depository) may be made only in accordance with Section 5.02(h), the rules of the Depository and the following:

(i) A holder of a beneficial interest in a Global Certificate of a Class may at any time exchange such beneficial interest for an Individual Certificate or Certificates of such Class.

(ii) A holder of an Individual Certificate or Certificates of a Class may exchange such Certificate or Certificates for a beneficial interest in the Global Certificate of such Class if such holder furnishes to the Securities Administrator a Rule 144A Certificate or comparable evidence as to its QIB status.

(iii) A holder of an Individual Certificate of a Class may exchange such Certificate for an equal aggregate principal amount of Individual Certificates of such Class in different authorized denominations without any certification.

(f) (i) Upon acceptance for exchange or transfer of an Individual Certificate of a Class for a beneficial interest in a Global Certificate of such Class as provided herein, the Securities Administrator shall cancel such Individual Certificate and shall (or shall request the

111

Depository to) endorse on the schedule affixed to the applicable Global Certificate (or on a continuation of such schedule affixed to the Global Certificate and made a part thereof) or otherwise make in its books and records an appropriate notation evidencing the date of such exchange or transfer and an increase in the certificate balance of the Global Certificate equal to the certificate balance of such Individual Certificate exchanged or transferred therefor.

(ii) Upon acceptance for exchange or transfer of a beneficial interest in a Global Certificate of a Class for an Individual Certificate of such Class as provided herein, the Securities Administrator shall (or shall request the Depository to) endorse on the schedule affixed to such Global Certificate (or on a continuation of such schedule affixed to such Global Certificate and made a part thereof) or otherwise make in its books and records an appropriate notation evidencing the date of such exchange or transfer and a decrease in the certificate balance of such Global Certificate equal to the certificate balance of such Individual Certificate issued in exchange therefor or upon transfer thereof.

(g) The Securities Legend shall be placed on any Individual Certificate issued in exchange for or upon transfer of another Individual Certificate or of a beneficial interest in a Global Certificate.

(h) Subject to the restrictions on transfer and exchange set forth in this Section 5.02, the holder of any Individual Certificate may transfer or exchange the same in whole or in part (in an initial certificate balance equal to the minimum authorized denomination set forth in Section 5.01(g) or any integral multiple of $1.00 in excess thereof) by surrendering such Certificate at the Corporate Trust Office of the Securities Administrator, or at the office of any transfer agent, together with an executed instrument of assignment and transfer satisfactory in form and substance to the Securities Administrator in the case of transfer and a written request for exchange in the case of exchange. The holder of a beneficial interest in a Global Certificate may, subject to the rules and procedures of the Depository, cause the Depository (or its nominee) to notify the Securities Administrator in writing of a request for transfer or exchange of such beneficial interest for an Individual Certificate or Certificates. Following a proper request for transfer or exchange, the Securities Administrator shall, within five Business Days of such request made at the Corporate Trust Office of the Securities Administrator, sign, countersign and deliver at the Corporate Trust Office of the Securities Administrator, to the transferee (in the case of transfer) or holder (in the case of exchange) or send by first class mail at the risk of the transferee (in the case of transfer) or holder (in the case of exchange) to such address as the transferee or holder, as applicable, may request, an Individual Certificate or Certificates, as the case may require, for a like aggregate Fractional Undivided Interest and in such authorized denomination or denominations as may be requested. The presentation for transfer or exchange of any Individual Certificate shall not be valid unless made at the Corporate Trust Office of the Securities Administrator by the registered holder in person, or by a duly authorized attorney-in-fact.

(i) At the option of the Certificateholders, Certificates may be exchanged for other Certificates of authorized denominations of a like Class and aggregate Fractional Undivided Interest, upon surrender of the Certificates to be exchanged at the Corporate Trust Office of the Securities Administrator; provided, however, that no Certificate may be exchanged for new Certificates unless the original Fractional Undivided Interest represented by each such new

112

Certificate (i) is at least equal to the minimum authorized denomination or (ii) is acceptable to the Depositor as indicated to the Securities Administrator in writing. Whenever any Certificates are so surrendered for exchange, the Securities Administrator shall sign and countersign and the Securities Administrator shall deliver the Certificates which the Certificateholder making the exchange is entitled to receive.

(j) If the Securities Administrator so requires, every Certificate presented or surrendered for transfer or exchange shall be duly endorsed by, or be accompanied by a written instrument of transfer, with a signature guarantee, in form satisfactory to the Securities Administrator, duly executed by the holder thereof or his or her attorney duly authorized in writing.

(k) No service charge shall be made for any transfer or exchange of Certificates, but the Securities Administrator may require 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.

(l) The Securities Administrator shall cancel all Certificates surrendered for transfer or exchange but shall retain such Certificates in accordance with its standard retention policy or for such further time as is required by the record retention requirements of the Exchange Act, and thereafter may destroy such Certificates.

Section 5.03. Mutilated, Destroyed, Lost or Stolen Certificates. (a) If (i) any mutilated Certificate is surrendered to the Securities Administrator, or the Securities Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and (ii) there is delivered to the Securities Administrator such security or indemnity as it may require to save it harmless, and (iii) the Securities Administrator has not received notice that such Certificate has been acquired by a third Person, the Securities Administrator shall sign, countersign and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and Fractional Undivided Interest but in each case bearing a different number. The mutilated, destroyed, lost or stolen Certificate shall thereupon be canceled of record by the Securities Administrator and shall be of no further effect and evidence no rights.

(b) Upon the issuance of any new Certificate under this Section 5.03, the Securities Administrator 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 Securities Administrator) connected therewith. Any duplicate Certificate issued pursuant to this Section 5.03 shall constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

113

Section 5.04. Persons Deemed Owners. Prior to due presentation of a Certificate for registration of transfer, the Depositor, the Securities Administrator and any agent of the Depositor or the Securities Administrator may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 6.01 and for all other purposes whatsoever. Neither the Depositor, the Securities Administrator nor any agent of the Depositor or the Securities Administrator shall be affected by notice to the contrary. No Certificate shall be deemed duly presented for a transfer effective on any Record Date unless the Certificate to be transferred is presented no later than the close of business on the third Business Day preceding such Record Date.

Section 5.05. Transfer Restrictions on Residual Certificates. (a) Residual Certificates, or interests therein, may not be transferred without the prior express written consent of the Tax Matters Person and the Seller, which cannot be unreasonably withheld. As a prerequisite to such consent, the proposed transferee must provide the Tax Matters Person, the Seller and the Securities Administrator with an affidavit that the proposed transferee is a Permitted Transferee (and an affidavit that it is a U.S. Person, unless, in the case of a Class R Certificate only, the Tax Matters Person and the Seller consent to the transfer to a person who is not a U.S. Person) as provided in Section 5.05(b).

(b) No transfer, sale or other disposition of a Residual Certificate (including a beneficial interest therein) may be made unless, prior to the transfer, sale or other disposition of a Residual Certificate, the proposed transferee (including the initial purchasers thereof) delivers to the Tax Matters Person, the Securities Administrator and the Depositor an affidavit in the form attached hereto as Exhibit E stating, among other things, that as of the date of such transfer (i) such transferee is a Permitted Transferee and that (ii) such transferee is not acquiring such Residual Certificate for the account of any person who is not a Permitted Transferee. The Tax Matters Person shall not consent to a transfer of a Residual Certificate if it has actual knowledge that any statement made in the affidavit issued pursuant to the preceding sentence is not true. Notwithstanding any transfer, sale or other disposition of a Residual Certificate to any Person who is not a Permitted Transferee, such transfer, sale or other disposition shall be deemed to be of no legal force or effect whatsoever and such Person shall not be deemed to be a Holder of a Residual Certificate for any purpose hereunder, including, but not limited to, the receipt of distributions thereon. If any purported transfer shall be in violation of the provisions of this Section 5.05(b), then the prior Holder thereof shall, upon discovery that the transfer of such Residual Certificate was not in fact permitted by this Section 5.05(b), be restored to all rights as a Holder thereof retroactive to the date of the purported transfer. None of the Securities Administrator, the Tax Matters Person or the Depositor shall be under any liability to any Person for any registration or transfer of a Residual Certificate that is not permitted by this Section 5.05(b) or for making payments due on such Residual Certificate to the purported Holder thereof or taking any other action with respect to such purported Holder under the provisions of this Agreement so long as the written affidavit referred to above was received with respect to such transfer, and the Tax Matters Person, the Securities Administrator and the Depositor, as applicable, had no knowledge that it was untrue. The prior Holder shall be entitled to recover from any purported Holder of a Residual Certificate that was in fact not a permitted transferee under this Section 5.05(b) at the time it became a Holder all payments made on such Residual Certificate. Each Holder of a Residual Certificate, by acceptance thereof, shall be deemed for all purposes to have consented to the provisions of this Section 5.05(b) and to any amendment of this Agreement deemed necessary (whether as a result of new legislation or otherwise) by counsel of the Tax Matters Person or the Depositor to ensure that the Residual Certificates are not transferred to any Person who is not a Permitted Transferee and that any transfer of such Residual Certificates will not cause the imposition of a tax upon the Trust or cause any REMIC to fail to qualify as a REMIC.

114

(c) The Class R-X Certificates (including a beneficial interest therein) and, unless the Tax Matters Person shall have consented in writing (which consent may be withheld in the Tax Matters Person’s sole discretion), the Class R Certificates (including a beneficial interest therein), may not be purchased by or transferred to any person who is not a United States Person.

(d) By accepting a Residual Certificate, the purchaser thereof agrees to be a Tax Matters Person if it is the Holder of the largest percentage interest of such Certificate, and appoints the Securities Administrator to act as its agent with respect to all matters concerning the tax obligations of the Trust.

Section 5.06. Restrictions on Transferability of Certificates. (a) No offer, sale, transfer or other disposition (including pledge) of any Certificate shall be made by any Holder thereof unless registered under the Securities Act, or an exemption from the registration requirements of the Securities Act and any applicable state securities or “Blue Sky” laws is available and the prospective transferee (other than the Depositor) of such Certificate signs and delivers to the Securities Administrator an Investment Letter, if the transferee is an Institutional Accredited Investor, in the form set forth as Exhibit F-l hereto, or a Rule 144A Certificate, if the transferee is a QIB, in the form set forth as Exhibit F-2 hereto. Notwithstanding the provisions of the immediately preceding sentence, no restrictions shall apply with respect to the transfer or registration of transfer of a beneficial interest in any Certificate that is a Global Certificate of a Class to a transferee that takes delivery in the form of a beneficial interest in the Global Certificate of such Class provided that each such transferee shall be deemed to have made such representations and warranties contained in the Rule 144A Certificate as are sufficient to establish that it is a QIB. In the case of a proposed transfer of any Certificate to a transferee other than a QIB, the Securities Administrator may require an Opinion of Counsel addressed to the Securities Administrator that such transaction is exempt from the registration requirements of the Securities Act. The cost of such opinion shall not be an expense of the Securities Administrator or the Trust Fund.

(b) The Private Certificates shall each bear a Securities Legend.

Section 5.07. ERISA Restrictions. (a) Subject to the provisions of subsection (b), no Residual Certificates or Private Certificates may be acquired directly or indirectly by, or on behalf of, an employee benefit plan or other retirement arrangement that is subject to Title I of ERISA or Section 4975 of the Code (a “Plan”), or by a person using “plan assets” of a Plan, unless the proposed transferee provides the Securities Administrator, with an Opinion of Counsel addressed to the Master Servicer and the Securities Administrator (upon which they may rely) that is satisfactory to the Securities Administrator, which opinion will not be at the expense of the Master Servicer or the Securities Administrator, that the purchase of such Certificates by or on behalf of such Plan is permissible under applicable law, will not constitute or result in a nonexempt prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Depositor, the Master Servicer or the Securities Administrator to any obligation in addition to those undertaken in the Agreement.

(b) Unless such Person has provided an Opinion of Counsel in accordance with Section 5.07(a), any Person acquiring an interest in a Global Certificate which is a Private Certificate, by acquisition of such Certificate, shall be deemed to have represented to the

115

Securities Administrator, and any Person acquiring an interest in a Private Certificate in definitive form shall represent in writing to the Securities Administrator, that it is not acquiring an interest in such Certificate directly or indirectly by, or on behalf of, or with “plan assets” of, an employee benefit plan or other retirement arrangement which is subject to Title I of ERISA and/or Section 4975 of the Code.

(c) Each beneficial owner of a Class I-M-1, Class I-M-2, Class I-B-1, Class I-B-2, Class II-B-1, Class II-B-2 or Class II-B-3 Certificate or any interest therein shall be deemed to have represented, by virtue of its acquisition or holding of that certificate or interest therein, that either (i) such Certificate is rated at least “BBB-” or its equivalent by Fitch, S&P or Moody’s, (ii) such beneficial owner is not a Plan or investing with “plan assets” of any Plan, or (iii) (1) it is an insurance company, (2) the source of funds used to acquire or hold the certificate or interest therein is an “insurance company general account,” as such term is defined in Prohibited Transaction Class Exemption (“PTCE”) 95-60, and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

(d) Neither the Master Servicer nor the Securities Administrator will be required to monitor, determine or inquire as to compliance with the transfer restrictions with respect to the Global Certificates. Any attempted or purported transfer of any Certificate in violation of the provisions of Sections (a), (b) or (c) above shall be void ab initio and such Certificate shall be considered to have been held continuously by the prior permitted Certificateholder. Any transferor of any Certificate in violation of such provisions, shall indemnify and hold harmless the Securities Administrator and the Master Servicer from and against any and all liabilities, claims, costs or expenses incurred by the Securities Administrator or the Master Servicer as a result of such attempted or purported transfer. The Securities Administrator shall have no liability for transfer of any such Global Certificates in or through book-entry facilities of any Depository or between or among Depository Participants or Certificate Owners made in violation of the transfer restrictions set forth herein.

Section 5.08. Rule 144A Information. For so long as any Private Certificates are outstanding, (1) the Seller will provide or cause to be provided to any holder of such Private Certificates and any prospective purchaser thereof designated by such a holder, upon the request of such holder or prospective purchaser, the information required to be provided to such holder or prospective purchaser by Rule 144A(d)(4) under the Securities Act; and (2) the Seller shall update such information from time to time in order to prevent such information from becoming false and misleading and will take such other actions as are necessary to ensure that the safe harbor exemption from the registration requirements of the Securities Act under Rule 144A is and will be available for resales of such Private Certificates conducted in accordance with Rule 144A.

(F) For any Undercollateralized Certificate Group on any Distribution Date prior to the Cross-Over Date, (i) 100% of amounts otherwise allocable to the Group II Subordinate Certificates in respect of principal will be distributed to the Group II Senior Certificates of such Undercollateralized Certificate Group on a pro rata basis in accordance with their respective Certificate Principal Balances in reduction of the Certificate Principal Balances thereof, until the aggregate Certificate Principal Balance of such Group II Senior Certificates is an amount equal to the aggregate Stated Principal Balance of the Group II Mortgage Loans in the related Sub-Loan Group and (ii) the Accrued Certificate Interest otherwise allocable to the Group II Subordinate Certificates on such Distribution Date will be reduced and distributed to such Group II Senior Certificates, to the extent of any amount due and unpaid on such Group II Senior Certificates, in an amount equal to one month’s interest at a rate equal to the related Pass-Through Rate for such Distribution Date on the related Undercollateralized Amount. Any such reduction in the Accrued Certificate Interest on the Group II Subordinate Certificates will be allocated in reverse order of their respective numerical designations,

124

commencing with the Class II-B-6 Certificates. If there exists more than one Undercollateralized Certificate Group on a Distribution Date, amounts distributable to such Undercollateralized Certificate Groups pursuant to this clause will be allocated between such Undercollateralized Certificate Groups, pro rata, based upon their respective Undercollateralized Amounts.

(G) If, after distributions have been made pursuant to priorities first and second of clauses (A) through (C) above on any Distribution Date, the remaining Available Funds for any Sub-Loan Group in Loan Group II is less than the Senior Optimal Principal Amount for that Sub-Loan Group, the Senior Optimal Principal Amount for such Sub-Loan Group shall be reduced by that amount, and the remaining Available Funds for such Sub-Loan Group will be distributed as principal among the related Classes of Group II Senior Certificates on a pro rata basis in accordance with their respective Certificate Principal Balances.

(H) On each Distribution Date, any Available Funds remaining after payment of interest and principal to the Classes of Certificates entitled thereto, will be distributed to the Class R Certificates; provided that if on any Distribution Date there are any Available Funds for any Sub-Loan Group in Loan Group II remaining after payment of interest and principal to a Class or Classes of Certificates entitled thereto, such amounts will be distributed to the other Classes of Group II Senior Certificates, pro rata, based upon their Certificate Principal Balances, until all amounts due to all Classes of Group II Senior Certificates have been paid in full, before any Available Funds are distributed in accordance with this clause to the Class R Certificates.

(I) On each Distribution Date, Carry Forward Shortfall Amounts, to the extent not covered by the related Cap Contract, (i) with respect to the Class II-B-1 Certificates, will be paid from amounts that would otherwise be allocable to pay Accrued Certificate Interest on the Class II-X-B1 Certificates, (ii) with respect to the Class II-B-2 Certificates, will be paid from amounts that would otherwise be allocable to pay Accrued Certificate Interest on the Class II-X-B2 Certificates, and (iii) with respect to the Class II-B-3 Certificates, will be paid from amounts that would otherwise be allocable to pay Accrued Certificate Interest on the Class II-X-B3 Certificates.

(b) No Accrued Certificate Interest will be payable with respect to any Class of Certificates after the Distribution Date on which the Certificate Principal Balance of such Certificate has been reduced to zero.

(c) If on any Distribution Date the Available Funds for the Group II Senior Certificates in any Certificate Group is less than the Accrued Certificate Interest on the related Senior Certificates for such Distribution Date prior to reduction for Net Interest Shortfalls and the interest portion of Realized Losses, the shortfall will be allocated to the holders of the Class of Senior Certificates in such Certificate Group on a pro rata basis in accordance with the amount of Accrued Certificate Interest for that Distribution Date absent such shortfalls. In addition, the amount of any interest shortfalls will constitute unpaid Accrued Certificate Interest and will be distributable to holders of the Certificates of the related Classes entitled to such amounts on subsequent Distribution Dates, to the extent of the applicable Available Funds after

125

current interest distributions as required herein. Any such amounts so carried forward will not bear interest. Shortfalls in interest payments will not be offset by a reduction in the servicing compensation of the Master Servicer or otherwise, except to the extent of applicable Compensating Interest Payments.

(e) On each Distribution Date, all amounts transferred from the Class XP Reserve Account representing Prepayment Charges in respect of the Prepayment Charge Loans with respect to the Group II Mortgage Loans received during the related Prepayment Period will be withdrawn from the Distribution Account and distributed by the Securities Administrator to the Holders of the Class II-XP Certificates and shall not be available for distribution to the Holders of any other Class of Certificates.

Section 6.03. Allocation of Losses and Subsequent Recoveries on the Group I Certificates. (a) On or prior to each Determination Date, the Master Servicer shall determine the amount of any Realized Loss in respect of each Group I Mortgage Loan that occurred during the immediately preceding calendar month, based on information provided by the related Servicer. Any Realized Losses with respect to the Group I Mortgage Loans shall be applied on each Distribution Date after the distributions provided for in Section 6.01, in reduction of the Certificate Principal Balance of the Class or Classes of Group I Certificates to the extent provided in the definition of Applied Realized Loss Amount.

(b) In addition, in the event that the Master Servicer or the Securities Administrator receives any Subsequent Recoveries from a Servicer, the Master Servicer shall deposit such funds into the Distribution Account pursuant to Section 4.01(c)(ii). If, after taking into account such Subsequent Recoveries, the amount of a Realized Loss is reduced, the amount of such Subsequent Recoveries will be applied to increase the Certificate Principal Balance of the Class of Group I Subordinate Certificates with the highest payment priority to which Applied Realized Loss Amounts have been allocated, but not by more than the amount of Applied Realized Loss Amounts previously allocated to that Class of Group I Subordinate Certificates. The amount of any remaining Subsequent Recoveries will be applied to sequentially increase the Certificate Principal Balance of the Group I Certificates, beginning with the Class of Group I Certificates with the next highest payment priority, up to the amount of such Applied Realized Loss Amounts previously allocated to such Class or Classes of Group I Certificates. Notwithstanding the forgoing, any Subsequent Recoveries will be allocated to the Group I Senior Certificates to the extent of any Applied Realized Loss Amounts before being applied to the Group I Subordinate Certificates. Holders of such Group I Certificates will not be entitled to any payments in respect of Current Interest 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 to the Certificate Principal Balance of each Group I Certificate of such Class in accordance with its respective Fractional Undivided Interest.

Section 6.04. Allocation of Losses and Subsequent Recoveries on the Group II Certificates. (a) On or prior to each Determination Date, the Master Servicer shall determine the amount of any Realized Loss in respect of each Group II Mortgage Loan that occurred during the immediately preceding calendar month, based on information provided by the related Servicer.

(b) With respect to any Group II Certificates on any Distribution Date, the principal portion of each Realized Loss on a Group II Mortgage Loan in a Sub-Loan Group shall be allocated as follows:

127

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

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

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

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

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

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

seventh, to the Senior Certificates in the related Certificate Group until the Certificate Principal Balances thereof has been reduced to zero in accordance with clause (d) below;

(c) Notwithstanding the foregoing clause (b), no such allocation of any Realized Loss shall be made on a Distribution Date to any Class of (i) Group II Subordinated Certificates to the extent that such allocation would result in the reduction of the aggregate Certificate Principal Balances of all Group II Certificates in as of such Distribution Date, after giving effect to all distributions and prior allocations of Realized Losses on the Group II Mortgage Loans on such date, to an amount less than the aggregate Stated Principal Balance of all of the Group II Mortgage Loans as of the first day of the month of such Distribution Date and (ii) Group II Senior Certificates in a Certificate Group to the extent that such allocation would result in the reduction of the aggregate Certificate Principal Balances of all the Group II Senior Certificates in such Certificate Group as of such Distribution Date, after giving effect to all distributions and prior allocations of Realized Losses on the Group II Mortgage Loans in the related Sub-Loan Group in Loan Group II on such date, to an amount less than the aggregate Stated Principal Balance of all of the Group II Mortgage Loans in such Sub-Loan Group as of the first day of the month of such Distribution Date (each such limitation in clause (i) and (ii), the “Loss Allocation Limitation”).

(d) The principal portion of any Realized Losses allocated to a Class of Certificates shall be allocated among the Certificates of such Class in proportion to their respective Certificate Principal Balances. The principal portion of any allocation of Realized Losses shall be accomplished by reducing the Certificate Principal Balance of the related Group II Certificates on the related Distribution Date. The principal portion of any Realized Losses allocated to the Sub-Loan Group II-1 Certificates will be allocated first to the Class II-1A-3 Certificates until the Certificate Principal Balance thereof has been reduced to zero and then to the Class II-1A-2 Certificates and Class II-1A-1 Certificates, pro rata, until their respective Certificate Principal Balances thereof have been reduced to zero. The principal portion of any Realized Losses allocated to the Sub-Loan Group II-2 Certificates will be allocated first to the

128

Class II-2A-2 Certificates until the Certificate Principal Balance thereof has been reduced to zero and then to the Class II-2A-1 Certificates until the Certificate Principal Balance thereof has been reduced to zero. The principal portion of any Realized Losses allocated to the Sub-Loan Group II-3 Certificates will be allocated first to the Class II-3A-2 Certificates until the Certificate Principal Balance thereof has been reduced to zero and then to the Class II-3A-1 Certificates until the Certificate Principal Balance thereof has been reduced to zero. Once the aggregate Certificate Principal Balance of the Certificates in a Certificate Group been reduced to zero, the principal portion of Realized Losses on the Mortgage Loans in the related Sub-Loan Group (if any) that are not allocated to the Subordinate Certificates pursuant to Section 6.02.2(b) will be allocated pro rata based upon their respective Certificate Principal Balances to the remaining Group II Senior Certificates of the other Certificate Groups, pro rata based upon their respective Certificate Principal Balances.

(e) Realized Losses shall be allocated on the Distribution Date in the month following the month in which such loss was incurred and, in the case of the principal portion thereof, after giving effect to distributions made on such Distribution Date.

(f) On each Distribution Date, the Securities Administrator shall determine the Subordinate Certificate Writedown Amount. Any Subordinate Certificate Writedown Amount shall effect a corresponding reduction in the Certificate Principal Balance of the Class II-B Certificates in the reverse order of their numerical Class designations.

(g) The applicable Senior Percentage of Net Interest Shortfalls will be allocated among the Group II Senior Certificates in the related Group II Certificate Group in proportion to the amount of Accrued Certificate Interest that would have been allocated thereto in the absence of such shortfalls. The applicable Subordinate Percentage of Net Interest Shortfall will be allocated among the Group II Subordinate Certificates in proportion to the amount of Accrued Certificate Interest that would have been allocated thereto in the absence of such shortfalls. The interest portion of any Realized Losses with respect to the Group II Mortgage Loans occurring on or prior to the Cross-Over Date will be allocated to the Class II-B Certificates in inverse order of their numerical Class designations. Following the Cross-Over Date, the interest portion of Realized Losses on the Group II Mortgage Loans will be allocated to the Group II Senior Certificates in the related Group II Certificate Group on a pro rata basis in proportion to the amount of Accrued Certificate Interest that would have been allocated thereto in the absence of such Realized Losses.

(h) In addition, in the event that the Master Servicer receives any Subsequent Recoveries from a Servicer, the Master Servicer shall deposit such funds into the Distribution Account pursuant to Section 4.01(c)(ii). If, after taking into account such Subsequent Recoveries, the amount of a Realized Loss is reduced, the amount of such Subsequent Recoveries will be applied to increase the Certificate Principal Balance of the Class of Group II Subordinate Certificates with the highest payment priority to which Realized Losses have been allocated, but not by more than the amount of Realized Losses previously allocated to that Class of Group II Subordinate Certificates pursuant to this Section 6.02.2. The amount of any remaining Subsequent Recoveries will be applied to sequentially increase the Certificate Principal Balance of the Group II Subordinate Certificates, beginning with the Class of Group II Subordinate Certificates with the next highest payment priority, up to the amount of such

129

Realized Losses previously allocated to such Class or Classes of Group II Certificates pursuant to this Section 6.02.2. Holders of such Certificates will not be entitled to any payments in respect of current interest 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 to the Certificate Principal Balance of each Group II Subordinate Certificate of such Class in accordance with its respective Fractional Undivided Interest.

Section 6.05. Cross-Collateralization. Notwithstanding the foregoing, on any Distribution Date on which the Certificate Principal Balance of the Group I Subordinate Certificates or the Group II Subordinate Certificates have been reduced to zero and a Realized Loss that is a Special Hazard Loss is to be allocated to the related Senior Certificates, such loss will be allocated among such Senior Certificates and the most subordinate outstanding class of non-related Subordinate Certificates on a pro rata basis, based on the Certificate Principal Balance thereof.

Section 6.06. Payments. (a) On each Distribution Date, other than the final Distribution Date, the Securities Administrator shall distribute to each Certificateholder of record as of the immediately preceding Record Date the Certificateholder’s pro rata share of its Class (based on the aggregate Fractional Undivided Interest represented by such Holder’s Certificates) of all amounts required to be distributed on such Distribution Date to such Class. The Securities Administrator shall calculate the amount to be distributed to each Class and, based on such amounts, the Securities Administrator shall determine the amount to be distributed to each Certificateholder. The Securities Administrator’s calculations of payments shall be based solely on information provided to the Securities Administrator by the Master Servicer. The Securities Administrator shall not be required to confirm, verify or recompute any such information but shall be entitled to rely conclusively on such information.

(b) Payment of the above amounts to each Certificateholder shall be made (i) by check mailed to each Certificateholder entitled thereto at the address appearing in the Certificate Register or (ii) upon receipt by the Securities Administrator on or before the fifth Business Day preceding the Record Date of written instructions from a Certificateholder by wire transfer to a United States dollar account maintained by the payee at any United States depository institution with appropriate facilities for receiving such a wire transfer; provided, however, that the final payment in respect of each Class of Certificates will be made only upon presentation and surrender of such respective Certificates at the office or agency of the Securities Administrator specified in the notice to Certificateholders of such final payment.

Within a reasonable period of time after the end of the preceding calendar year beginning in 2006, the Securities Administrator will furnish a report to each Holder of the Certificates of record at any time during the prior calendar year as to the aggregate of amounts reported pursuant to subclauses (a)(i) and (a)(ii) above with respect to the Certificates, plus information with respect to the amount of servicing compensation and such other customary information as the Securities Administrator may determine to be necessary and/or to be required by the Internal Revenue Service or by a federal or state law or rules or regulations to enable such Holders to prepare their tax returns for such calendar year. Such obligations shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Securities Administrator or the Trustee pursuant to the requirements of the Code.

Section 6.08. Monthly Advances. If the Scheduled Payment on a Mortgage Loan that was due on a related Due Date is delinquent, other than as a result of application of the Relief Act, and for which the related Servicer was required to make an advance pursuant to the related Servicing Agreement exceeds the amount deposited in the Distribution Account which will be used for an advance with respect to such Mortgage Loan, the Master Servicer will deposit in the Distribution Account not later than the Distribution Account Deposit Date immediately preceding the related Distribution Date an amount equal to such deficiency, net of the Servicing Fee for such Mortgage Loan except to the extent the Master Servicer determines any such advance to be a Nonrecoverable Advance. Subject to the foregoing, the Master Servicer, as successor servicer, shall continue to make such advances through the date that the related Servicer is required to do so under its Servicing Agreement; provided, however, that if the Master Servicer deems an advance to be a Nonrecoverable Advance, on the Distribution Account Deposit Date, the Master Servicer shall not be obligated to make such advance and shall present an Officer’s Certificate to the Trustee (i) stating that the Master Servicer elects not to make a Monthly Advance in a stated amount and (ii) detailing the reason it deems the advance to be a Nonrecoverable Advance.

Section 6.09. Compensating Interest Payments. The Master Servicer shall deposit in the Distribution Account not later than each Distribution Account Deposit Date an amount equal to the lesser of (i) the sum of the aggregate amounts required to be paid by the Servicers under the Servicing Agreements with respect to subclauses (a) and (b) of the definition of Interest Shortfall with respect to the Mortgage Loans for the related Distribution Date, and not so paid by the related Servicers and (ii) the Master Servicer Compensation for such Distribution Date (such amount, the “Compensating Interest Payment”). The Master Servicer shall not be entitled to any reimbursement of any Compensating Interest Payment.

Section 6.10. Distributions on REMIC Regular Interests. (a) On each Distribution Date, the Securities Administrator shall be deemed to distribute to the Trustee on behalf of REMIC III as the holder of the REMIC I Regular Interests and REMIC II Regular Interests, those portions of the REMIC I Distribution Amount not designated to Component I of the Class R Certificate, in the amounts and in accordance with the priorities set forth in the definition of REMIC I Distribution Amount and those portions of the REMIC II Distribution Amount not designated to Component II of the Class R Certificate, in the amounts and in accordance with the priorities set forth in the definition of REMIC II Distribution Amount.

134

(b) On each Distribution Date, the Securities Administrator shall be deemed to distribute to the Trustee on behalf of REMIC IV as the holder of the REMIC III Regular Interests, those portions of the REMIC III Distribution Amount not designated to Component III of the Class R Certificate, in the amounts and in accordance with the priorities set forth in the definition of REMIC III Distribution Amount.

(c) On each Distribution Date, the Securities Administrator shall be deemed to distribute the REMIC IV Distribution Amount to: (i) the holders of the Certificates (other than the Class B-IO Certificates), as the holders of the REMIC IV Interests (other than REMIC IV Regular Interests B-IO-I and B-IO-P) and (ii) itself on behalf of REMIC V, as the holder of REMIC IV Regular Interests B-IO-I and B-IO-P, in the amounts and in accordance with the priorities set forth in the definition of REMIC IV Distribution Amount.

(d) On each Distribution Date, the Securities Administrator shall be deemed to distribute to the holder of the Class B-IO Certificates, as the holder of REMIC V Regular Interest, the amounts set forth in the definition of REMIC V Distribution Amount.

(e) Notwithstanding the deemed distributions on the REMIC Regular Interests described in this Section 6.07, distributions of funds from the Distribution Account shall be made only in accordance with Sections 6.01 and 6.02.

The Master Servicer

Section 7.01. Liabilities of the Master Servicer. The Master Servicer shall be liable in accordance herewith only to the extent of the obligations specifically imposed upon and undertaken by it herein.

Section 7.02. Merger or Consolidation of the Master Servicer. (a) The Master Servicer will keep in full force and effect its existence, rights and franchises as a corporation under the laws of the state of its incorporation, and will obtain and preserve its qualification to do business as a foreign corporation in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement, the Certificates or any of the Mortgage Loans and to perform its duties under this Agreement.

(b) Any Person into which the Master Servicer may be merged or consolidated, or any corporation resulting from any merger or consolidation to which the Master Servicer shall be a party, or any Person succeeding to the business of the Master Servicer, shall be the successor of the Master Servicer hereunder, 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.

Section 7.03. Indemnification of the Trustee, the Master Servicer and the Securities Administrator. (a) The Master Servicer agrees to indemnify the Indemnified Persons for, and to hold them harmless against, any loss, liability or expense (including reasonable legal fees and disbursements of counsel) incurred on their part that may be sustained in connection with, arising out of, or relating to, any claim or legal action (including any pending or threatened claim or legal action) relating to this Agreement, the Servicing Agreements, the Assignment Agreements or the Certificates or the powers of attorney delivered by the Trustee hereunder (i) related to the Master Servicer’s failure to perform its duties in compliance with this Agreement (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement) or (ii) incurred by reason of the Master Servicer’s willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder, provided, in each case, that with respect to any such claim or legal action (or pending or threatened claim or legal action), the Trustee shall have given the Master Servicer and the Depositor written notice thereof promptly after the Trustee shall have with respect to such claim or legal action knowledge thereof. The Trustee’s failure to give any such notice shall not affect the Trustee’s right to indemnification hereunder, except to the extent the Master Servicer is materially prejudiced by such failure to give notice. This indemnity shall survive the resignation or removal of the Trustee, Master Servicer or the Securities Administrator and the termination of this Agreement.

(b) The Depositor will indemnify any Indemnified Person for any loss, liability or expense of any Indemnified Person not otherwise covered by the Master Servicer’s indemnification pursuant to Section 7.03(a).

Section 7.04. Limitations on Liability of the Master Servicer and Others. Subject to the obligation of the Master Servicer to indemnify the Indemnified Persons pursuant to Section 7.03:

136

(a) Neither the Master Servicer nor any of the directors, officers, employees or agents of the Master Servicer shall be under any liability to the Indemnified Persons, the Depositor, the Trust Fund or the Certificateholders for taking any action or for refraining from taking any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Master Servicer or any such Person against any breach of warranties or representations made herein or any liability which would otherwise be imposed by reason of such Person’s willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder.

(b) The Master Servicer and any director, officer, employee or agent of the Master Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder.

(c) The Master Servicer, the Custodian and any director, officer, employee or agent of the Master Servicer or the Custodian shall be indemnified by the Trust and held harmless thereby against any loss, liability or expense (including reasonable legal fees and disbursements of counsel) incurred on their part that may be sustained in connection with, arising out of, or related to, any claim or legal action (including any pending or threatened claim or legal action) relating to this Agreement, the Certificates or any Servicing Agreement (except to the extent that the Master Servicer is indemnified by the Servicer thereunder), other than (i) any such loss, liability or expense related to the Master Servicer’s failure to perform its duties in compliance with this Agreement (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement), or to the Custodian’s failure to perform its duties under the Custodial Agreement, respectively, or (ii) any such loss, liability or expense incurred by reason of the Master Servicer’s or the Custodian’s willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or under the Custodial Agreement, as applicable, or by reason of reckless disregard of obligations and duties hereunder or under the Custodial Agreement, as applicable.

(d) The Master Servicer shall not be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its duties under this Agreement and that in its opinion may involve it in any expense or liability; provided, however, the Master Servicer may in its discretion, with the consent of the Trustee (which consent shall not be unreasonably withheld), undertake any such action which it may deem necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund, and the Master Servicer shall be entitled to be reimbursed therefor out of the Distribution Account as provided by Section 4.05. Nothing in this Section 7.04(d) shall affect the Master Servicer’s obligation to supervise, or to take such actions as are necessary to ensure, the servicing and administration of the Mortgage Loans pursuant to Section 3.01(a).

(e) In taking or recommending any course of action pursuant to this Agreement, unless specifically required to do so pursuant to this Agreement, the Master Servicer shall not be required to investigate or make recommendations concerning potential liabilities which the Trust might incur as a result of such course of action by reason of the condition of the Mortgaged Properties but shall give notice to the Trustee if it has notice of such potential liabilities.

137

(f) The Master Servicer shall not be liable for any acts or omissions of any Servicer, except as otherwise expressly provided herein.

Section 7.05. Master Servicer Not to Resign. Except as provided in Section 7.07, the Master Servicer shall not resign from the obligations and duties hereby imposed on it except upon a determination that any such duties hereunder are no longer permissible under applicable law and such impermissibility cannot be cured. Any such determination permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Independent Counsel addressed to the Trustee to such effect delivered to the Trustee. No such resignation by the Master Servicer shall become effective until the Company or the Trustee or a successor to the Master Servicer reasonably satisfactory to the Trustee shall have assumed the responsibilities and obligations of the Master Servicer in accordance with Section 8.02 hereof. The Trustee shall notify the Rating Agencies upon its receipt of written notice of the resignation of the Master Servicer.

Section 7.06. Successor Master Servicer. In connection with the appointment of any successor master servicer or the assumption of the duties of the Master Servicer, the Company or the Trustee may make such arrangements for the compensation of such successor master servicer out of payments on the Mortgage Loans as the Company or the Trustee and such successor master servicer shall agree. If the successor master servicer does not agree that such market value is a fair price, such successor master servicer shall obtain two quotations of market value from third parties actively engaged in the servicing of single-family mortgage loans. Notwithstanding the foregoing, the compensation payable to a successor master servicer may not exceed the compensation which the Master Servicer would have been entitled to retain if the Master Servicer had continued to act as Master Servicer hereunder.

Section 7.07. Sale and Assignment of Master Servicing. The Master Servicer may sell and assign its rights and delegate its duties and obligations in its entirety as Master Servicer under this Agreement and the Company may terminate the Master Servicer without cause and select a new Master Servicer; provided, however, that: (i) the purchaser or transferee accepting such assignment and delegation (a) shall be a Person which shall be qualified to service mortgage loans for Fannie Mae or Freddie Mac; (b) shall have a net worth of not less than $10,000,000 (unless otherwise approved by each Rating Agency pursuant to clause (ii) below); (c) shall be reasonably satisfactory to the Trustee (as evidenced in a writing signed by the Trustee); and (d) shall execute and deliver to the Trustee an agreement, in form and substance reasonably satisfactory to the Trustee, which contains an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed or observed by it as master servicer under this Agreement, any custodial agreement from and after the effective date of such agreement; (ii) each Rating Agency shall be given prior written notice of the identity of the proposed successor to the Master Servicer and each Rating Agency’s rating of the Certificates in effect immediately prior to such assignment, sale and delegation will not be downgraded, qualified or withdrawn as a result of such assignment, sale and delegation, as evidenced by a letter to such effect delivered to the Master Servicer and the Trustee (at the expense of the Master Servicer); (iii) the Master Servicer assigning and selling the master servicing shall deliver to the Trustee an Officer’s Certificate and an Opinion of Independent Counsel addressed to the Trustee, each stating that all conditions precedent to such action under this Agreement have been completed and such action is permitted by and complies with the

138

terms of this Agreement; and (iv) in the event the Master Servicer is terminated without cause by the Company, the Company shall pay the terminated Master Servicer a termination fee equal to 0.25% of the aggregate Stated Principal Balance of the Mortgage Loans at the time the master servicing of the Mortgage Loans is transferred to the successor master servicer. No such assignment or delegation shall affect any rights or liability of the Master Servicer arising prior to the effective date thereof.

139

ARTICLE VIII

Default

Section 8.01. Events of Default. “Event of Default,” wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body) and only with respect to the defaulting Master Servicer:

(a) The Master Servicer fails to cause to be deposited in the Distribution Account any amount so required to be deposited pursuant to this Agreement (other than a Monthly Advance), and such failure continues unremedied for a period of three Business Days after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer; or

(b) The Master Servicer fails to observe or perform in any material respect any other material covenants and agreements set forth in this Agreement to be performed by it, which covenants and agreements materially affect the rights of Certificateholders, and such failure continues unremedied for a period of 60 days after the date on which written notice of such failure, properly requiring the same to be remedied, shall have been given to the Master Servicer by the Trustee or to the Master Servicer and the Trustee by the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust Fund; or

(c) There is entered against the Master Servicer a decree or order by a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a conservator, receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding up or liquidation of its affairs, and the continuance of any such decree or order is unstayed and in effect for a period of 60 consecutive days, or an involuntary case is commenced against the Master Servicer under any applicable insolvency or reorganization statute and the petition is not dismissed within 60 days after the commencement of the case; or

(d) The Master Servicer consents to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the Master Servicer or substantially all of its property; or the Master Servicer admits in writing its inability to pay its debts generally as they become due, files a petition to take advantage of any applicable insolvency or reorganization statute, makes an assignment for the benefit of its creditors, or voluntarily suspends payment of its obligations;

(e) The Master Servicer assigns or delegates its duties or rights under this Agreement in contravention of the provisions permitting such assignment or delegation under Sections 7.05 or 7.07;

(f) The Master Servicer fails to comply with Section 3.16, Section 3.17 and Section 3.18; or

140

(g) The Master Servicer fails to cause to be deposited, in the Distribution Account any Monthly Advance (other than a Nonrecoverable Advance) by 5:00 p.m. New York City time on the Distribution Account Deposit Date.

In each and every such case, so long as such Event of Default with respect to the Master Servicer shall not have been remedied, either the Trustee or the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the principal of the Trust Fund, by notice in writing to the Master Servicer (and to the Trustee if given by such Certificateholders), with a copy to the Rating Agencies, and with the consent of the Company, may terminate all of the rights and obligations (but not the liabilities) of the Master Servicer under this Agreement and in and to the Mortgage Loans and/or the REO Property serviced by the Master Servicer and the proceeds thereof. Upon the receipt by the Master Servicer of the written notice, all authority and power of the Master Servicer under this Agreement, whether with respect to the Certificates, the Mortgage Loans, REO Property or under any other related agreements (but only to the extent that such other agreements relate to the Mortgage Loans or related REO Property) shall, subject to Section 8.02, automatically and without further action pass to and be vested in the Trustee pursuant to this Section 8.01; and, without limitation, 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. The Master Servicer agrees to cooperate with the Trustee in effecting the termination of the Master Servicer’s rights and obligations hereunder, including, without limitation, the transfer to the Trustee of (i) the property and amounts which are then or should be part of the Trust or which thereafter become part of the Trust; and (ii) originals or copies of all documents of the Master Servicer reasonably requested by the Trustee to enable it to assume the Master Servicer’s duties thereunder. In addition to any other amounts which are then, or, notwithstanding the termination of its activities under this Agreement, may become payable to the Master Servicer under this Agreement, the Master Servicer shall be entitled to receive, out of any amount received on account of a Mortgage Loan or related REO Property, that portion of such payments which it would have received as reimbursement under this Agreement if notice of termination had not been given. The termination of the rights and obligations of the Master Servicer shall not affect any obligations incurred by the Master Servicer prior to such termination.

Notwithstanding the foregoing, if an Event of Default described in clause (vi) of this Section 8.01 shall occur, the Trustee shall, by notice in writing to the Master Servicer, which may be delivered by telecopy, immediately terminate all of the rights and obligations of the Master Servicer thereafter arising under this Agreement, but without prejudice to any rights it may have as a Certificateholder or to reimbursement of Monthly Advances and other advances of its own funds, and the Trustee shall act as provided in Section 8.02 to carry out the duties of the Master Servicer, including the obligation to make any Monthly Advance the nonpayment of which was an Event of Default described in clause (vi) of this Section 8.01. Any such action taken by the Trustee must be prior to the distribution on the relevant Distribution Date.

Section 8.02. Trustee to Act; Appointment of Successor. (a) Upon the receipt by the Master Servicer of a notice of termination pursuant to Section 8.01 or an Opinion of Independent

141

Counsel pursuant to Section 7.05 to the effect that the Master Servicer is legally unable to act or to delegate its duties to a Person which is legally able to act, the Trustee shall automatically become the successor in all respects to the Master Servicer in its capacity under this Agreement and the transactions set forth or provided for herein and shall thereafter be subject to all the responsibilities, duties, liabilities and limitations on liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof; provided, however, that the Company shall have the right to either (a) immediately assume the duties of the Master Servicer or (b) select a successor master servicer; provided further, however, that the Trustee shall have no obligation whatsoever with respect to any liability (other than advances deemed recoverable and not previously made) incurred by the Master Servicer at or prior to the time of termination. As compensation therefor, but subject to Section 7.06, the Trustee shall be entitled to compensation which the Master Servicer would have been entitled to retain if the Master Servicer had continued to act hereunder, except for those amounts due the Master Servicer as reimbursement permitted under this Agreement for advances previously made or expenses previously incurred. Notwithstanding the above, the Trustee may, if it shall be unwilling so to act, or shall, if it is legally unable so to act, appoint or petition a court of competent jurisdiction to appoint, any established housing and home finance institution which is a Fannie Mae- or Freddie Mac-approved servicer, and with respect to a successor to the Master Servicer only, having a net worth of not less than $10,000,000, 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; provided, that the Trustee shall obtain a letter from each Rating Agency that the ratings, if any, on each of the Certificates will not be lowered as a result of the selection of the successor to the Master Servicer. Pending appointment of a successor to the Master Servicer hereunder, the Trustee shall 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 the Mortgage Loans as it and such successor shall agree; provided, however, that the provisions of Section 7.06 shall apply, the compensation shall not be in excess of that which the Master Servicer would have been entitled to if the Master Servicer had continued to act hereunder, and that such successor shall undertake and assume the obligations of the Trustee to pay compensation to any third Person acting as an agent or independent contractor in the performance of master servicing responsibilities hereunder. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

(b) If the Trustee shall succeed to any duties of the Master Servicer respecting the Mortgage Loans as provided herein, it shall do so in a separate capacity and not in its capacity as Trustee and, accordingly, the provisions of Article IX shall be inapplicable to the Trustee in its duties as the successor to the Master Servicer in the servicing of the Mortgage Loans (although such provisions shall continue to apply to the Trustee in its capacity as Trustee); the provisions of Article VII, however, shall apply to it in its capacity as successor master servicer.

The costs and expenses of the Trustee in connection with the termination of the Master Servicer, the appointment of a successor master servicer and, if applicable, any transfer of servicing, including, without limitation, all costs and expenses associated with the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data as may be required by the Trustee to correct any errors or insufficiencies in the servicing data or otherwise to enable the Trustee or the successor master servicer to service the Mortgage

142

Loans properly and effectively, to the extent not paid by the terminated Master Servicer, shall be payable to the Trustee pursuant to Section 9.05. Any successor to the Master Servicer acting as successor servicer under any Servicing Agreement shall give notice to the applicable Mortgagors of such change of servicer and shall, during the term of its service as successor master servicer maintain in force the policy or policies that the Master Servicer is required to maintain pursuant to Section 3.04.

Section 8.03. Notification to Certificateholders. Upon any termination or appointment of a successor to the Master Servicer, the Trustee shall give prompt written notice thereof to the Rating Agencies and the Securities Administrator, and the Securities Administrator shall give prompt written notice thereof to the Certificateholders at their respective addresses appearing in the Certificate Register.

Section 8.04. Waiver of Defaults. The Trustee shall transmit by mail to the Securities Administrator, who shall give prompt written notice thereof to all Certificateholders, within 60 days after the occurrence of any Event of Default actually known to a Responsible Officer of the Trustee, unless such Event of Default shall have been cured, notice of each such Event of Default. The Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund may, on behalf of all Certificateholders, waive any default by the Master Servicer in the performance of its obligations hereunder and the consequences thereof, except a default in the making of or the causing to be made any required distribution on the Certificates, which default may only be waived by Holders of Certificates evidencing Fractional Undivided Interests aggregating 100% of the Trust Fund. Upon any such waiver of a past default, such default shall be deemed to cease to exist, and any Event of Default arising therefrom shall be deemed to have been timely remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived. The Securities Administrator shall give notice of any such waiver to the Trustee, who shall then give such notice to the Rating Agencies.

Section 8.05. List of Certificateholders. Upon written request of three or more Certificateholders of record, for purposes of communicating with other Certificateholders with respect to their rights under this Agreement, the Securities Administrator will afford such Certificateholders access during business hours to the most recent list of Certificateholders held by the Securities Administrator.

143

If an Event of Default has occurred and has not been cured or waived, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and subject to Section 8.02(b) use the same degree of care and skill in their exercise, as a prudent person would exercise under the circumstances in the conduct of his own affairs.

(b) Upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments which are specifically required to be furnished to the Trustee and the Securities Administrator pursuant to any provision of this Agreement, the Trustee and the Securities Administrator, respectively, shall examine them to determine whether they are in the form required by this Agreement; provided, however, that neither the Trustee nor the Securities Administrator shall be responsible for the accuracy or content of any resolution, certificate, statement, opinion, report, document, order or other instrument furnished hereunder; provided, further, that neither the Trustee nor the Securities Administrator shall be responsible for the accuracy or verification of any calculation provided to it pursuant to this Agreement.

(i) Prior to the occurrence of an Event of Default, and after the curing or waiver of all such Events of Default which may have occurred, the duties and obligations of the Trustee and the Securities Administrator shall be determined solely by the express provisions of this Agreement, neither the Trustee nor the Securities Administrator shall be liable except for the performance of their respective duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee or the Securities Administrator and, in the absence of bad faith on the part of the Trustee or the Securities Administrator, respectively, the Trustee or the Securities Administrator, respectively, may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee or the Securities Administrator, respectively, and conforming to the requirements of this Agreement;

(ii) Neither the Trustee nor the Securities Administrator shall be liable in its individual capacity for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee or an officer of the Securities Administrator, respectively,

(iii) Neither the Trustee nor the Securities Administrator shall be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the directions of the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust Fund, if such action or non-action relates to the time, method and place of conducting any proceeding for any remedy available to the Trustee or the Securities Administrator, respectively, or exercising any trust or other power conferred upon the Trustee or the Securities Administrator, respectively, under this Agreement;

(iv) The Trustee shall not be required to take notice or be deemed to have notice or knowledge of any default or Event of Default unless a Responsible Officer of the Trustee’s Corporate Trust Office shall have actual knowledge thereof. In the absence of such notice, the Trustee may conclusively assume there is no such default or Event of Default;

(v) The Trustee shall not in any way be liable by reason of any insufficiency in any Account held by or in the name of Trustee unless it is determined by a court of competent jurisdiction that the Trustee’s gross negligence or willful misconduct was the primary cause of such insufficiency (except to the extent that the Trustee is obligor and has defaulted thereon);

(vi) The Securities Administrator shall not in any way be liable by reason of any insufficiency in any Account held by the Securities Administrator hereunder or any Account held by the Securities Administrator in the name of the Trustee unless it is determined by a court of competent jurisdiction that the Securities Administrator’s gross negligence or willful misconduct was the primary cause of such insufficiency (except to the extent that the Securities Administrator is obligor and has defaulted thereon);

(vii) Anything in this Agreement to the contrary notwithstanding, in no event shall the Trustee or the Securities Administrator be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee or the Securities Administrator, respectively, has been advised of the likelihood of such loss or damage and regardless of the form of action;

(viii) None of the Securities Administrator, the Master Servicer, the Depositor, the Company, the Custodian, the Counterparty or the Trustee shall be responsible for the acts or omissions of the other, it being understood that this Agreement shall not be construed to render them partners, joint venturers or agents of one another and

(ix) Neither the Trustee nor the Securities Administrator shall be required to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it, and none of the provisions contained in this Agreement shall in any event require the Trustee or the Securities Administrator to perform, or be responsible for the manner of performance of, any of the obligations of the Master Servicer under this Agreement, except during such time, if any, as the Trustee shall be the successor to,

145

and be vested with the rights, duties, powers and privileges of, the Master Servicer in accordance with the terms of this Agreement.

(e) All funds received by the Master Servicer and the Securities Administrator and required to be deposited in the Pre-Funding Account, the Pre-Funding Reserve Account, the Interest Coverage Account or the Distribution Account pursuant to this Agreement will be promptly so deposited by the Master Servicer or the Securities Administrator, as applicable.

Nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default of which a Responsible Officer of the Trustee has actual knowledge (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Agreement, and to use the same degree of care and skill in their exercise, as a prudent person would exercise under the circumstances in the conduct of his own affairs;

146

(e) Neither the Trustee nor the Securities Administrator shall be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing to do so by Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust Fund and provided that the payment within a reasonable time to the Trustee or the Securities Administrator, as applicable, of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the Opinion of the Trustee or the Securities Administrator, as applicable, reasonably assured to the Trustee or the Securities Administrator, as applicable, by the security afforded to it by the terms of this Agreement. The Trustee or the Securities Administrator may require reasonable indemnity against such expense or liability as a condition to taking any such action. The reasonable expense of every such examination shall be paid by the Certificateholders requesting the investigation;

(f) The Trustee and the Securities Administrator may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or through Affiliates, agents or attorneys; provided, however, that the Trustee may not appoint any agent (other than the Custodian) to perform its custodial functions with respect to the Mortgage Files or paying agent functions under this Agreement without the express written consent of the Master Servicer, which consent will not be unreasonably withheld. Neither the Trustee nor the Securities Administrator shall be liable or responsible for the misconduct or negligence of any of the Trustee’s or the Securities Administrator’s agents or attorneys or a custodian or paying agent appointed hereunder by the Trustee or the Securities Administrator with due care and, when required, with the consent of the Master Servicer;

(g) Should the Trustee or the Securities Administrator deem the nature of any action required on its part, other than a payment or transfer by the Securities Administrator under Section 4.01(b) or Section 4.04, to be unclear, the Trustee or the Securities Administrator, respectively, may require prior to such action that it be provided by the Depositor with reasonable further instructions;

(h) The right of the Trustee or the Securities Administrator to perform any discretionary act enumerated in this Agreement shall not be construed as a duty, and neither the Trustee nor the Securities Administrator shall be accountable for other than its negligence or willful misconduct in the performance of any such act;

147

Section 9.03. Trustee and Securities Administrator Not Liable for Certificates or Mortgage Loans. The recitals contained herein and in the Certificates (other than the signature and countersignature of the Securities Administrator on the Certificates) shall be taken as the statements of the Depositor, and neither the Trustee nor the Securities Administrator shall have any responsibility for their correctness. Neither the Trustee nor the Securities Administrator makes any representation as to the validity or sufficiency of the Certificates (other than the signature and countersignature of the Securities Administrator on the Certificates) or of any Mortgage Loan except as expressly provided in Sections 2.02 and 2.05 hereof; provided, however, that the foregoing shall not relieve the Trustee of the obligation to review the Mortgage Files pursuant to Sections 2.02 and 2.04. The Securities Administrator’s signature and countersignature (or countersignature of its agent) on the Certificates shall be solely in its capacity as Securities Administrator and shall not constitute the Certificates an obligation of the Securities Administrator in any other capacity. Neither the Trustee nor the Securities Administrator shall be accountable for the use or application by the Depositor of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Depositor with respect to the Mortgage Loans. Subject to the provisions of Section 2.05, neither the Trustee nor the Securities Administrator shall be responsible for the legality or validity of this Agreement or any document or instrument relating to this Agreement, the validity of the execution of this Agreement or of any supplement hereto or instrument of further assurance, or the validity, priority, perfection or sufficiency of the security for the Certificates issued hereunder or intended to be issued hereunder. Neither the Trustee nor the Securities Administrator shall at any time have any responsibility or liability for or with respect to the legality, validity and enforceability of any Mortgage or any Mortgage Loan, or the perfection and priority of any Mortgage or the maintenance of any such perfection and priority, or for or with respect to the sufficiency of the Trust Fund or its ability to generate the payments to be distributed to Certificateholders, under this Agreement. Neither the Trustee nor the Securities Administrator shall have any responsibility for filing any financing or continuation statement in any public office at any time or to otherwise perfect or maintain the perfection of any security interest or lien granted to it hereunder or to record this Agreement other than any continuation statements filed by the Trustee pursuant to Section 3.20.

Section 9.04. Trustee and Securities Administrator May Own Certificates. The Trustee and the Securities Administrator in their individual capacities or in any capacity other than as Trustee or Securities Administrator, hereunder may become the owner or pledgee of any Certificates with the same rights it would have if it were not the Trustee or the Securities Administrator, as applicable, and may otherwise deal with the parties hereto.

Section 9.05. Trustee’s and Securities Administrator’s Fees and Expenses. The fees and expenses of the Trustee and the Securities Administrator shall be paid in accordance with a side letter agreement between the Trustee and the Master Servicer. In addition, the Trustee and the Securities Administrator will be entitled to recover from the Distribution Account pursuant to Section 4.05(l) all reasonable out-of-pocket expenses, disbursements and advances and the expenses of the Trustee and the Securities Administrator, respectively, in connection with such Person's compliance with Section 3.23, any Event of Default, any breach of this Agreement, the termination of the Master Servicer, the appointment of a successor master servicer and, if applicable, any transfer of servicing as set forth in Section 8.02(b), or as otherwise set forth herein, or any claim or legal action (including any pending or threatened claim or legal action)

148

incurred or made by or against the Trustee or the Securities Administrator, respectively, in the administration of the trusts hereunder (including the reasonable compensation, expenses and disbursements of its counsel) except any such expense, disbursement or advance as may arise from its negligence or intentional misconduct or which is the responsibility of the Certificateholders. If funds in the Distribution Account are insufficient therefor, the Trustee and the Securities Administrator shall recover such expenses from the Depositor. Such compensation and reimbursement obligation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust.

Section 9.06. Eligibility Requirements for Trustee and Securities Administrator. The Trustee and any successor Trustee and the Securities Administrator and any successor Securities Administrator shall during the entire duration of this Agreement be a state bank or trust company or a national banking association organized and doing business under the laws of such state or the United States of America, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus and undivided profits of at least $40,000,000 or, in the case of a successor Trustee, $50,000,000, subject to supervision or examination by federal or state authority and, in the case of the Trustee, rated “BBB” or higher by S&P with respect to their long-term rating and rated “BBB” or higher by S&P and “Baa2” or higher by Moody’s with respect to any outstanding long-term unsecured unsubordinated debt, and, in the case of a successor Trustee or successor Securities Administrator other than pursuant to Section 9.10, rated in one of the two highest long-term debt categories of, or otherwise acceptable to, each of the Rating Agencies.

In the event that the Trustee or Securities Administrator is removed by the Holders of Certificates in accordance with this Section 9.08(c), the Holders of such Certificates shall be responsible for paying any compensation payable hereunder to a successor Trustee or successor Securities Administrator, in excess of the amount paid hereunder to the predecessor Trustee or predecessor Securities Administrator, as applicable.

(d) No resignation or removal of the Trustee or the Securities Administrator and appointment of a successor Trustee or Securities Administrator pursuant to any of the provisions of this Section 9.08 shall become effective except upon appointment of and acceptance of such appointment by the successor Trustee or Securities Administrator as provided in Section 9.09.

Section 9.09. Successor Trustee and Successor Securities Administrator. (a) Any successor Trustee or Securities Administrator appointed as provided in Section 9.08 shall execute, acknowledge and deliver to the Depositor and to its predecessor Trustee or Securities Administrator an instrument accepting such appointment hereunder. The resignation or removal of the predecessor Trustee or Securities Administrator shall then become effective and such successor Trustee or Securities Administrator, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee or Securities Administrator herein. The predecessor Trustee or Securities Administrator shall, after its receipt of payment in full of its outstanding fees and expenses promptly deliver to the successor Trustee or Securities

150

Administrator, as applicable, all assets and records of the Trust held by it hereunder, and the Depositor and the predecessor Trustee or Securities Administrator, as applicable, 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 or Securities Administrator, as applicable, all such rights, powers, duties and obligations.

Such succession shall be valid without the execution, delivery of notice or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 9.11. Appointment of Co-Trustee or Separate Trustee. (a) Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust or property constituting the same may at the time be located, the Depositor and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee and the Depositor to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust, and to vest in such Person or Persons, in such capacity, such title to the Trust, or any part thereof, and, subject to the other provisions of this Section 9.11, such powers, duties, obligations, rights and trusts as the Depositor and the Trustee may consider necessary or desirable.

(b) If the Depositor shall not have joined in such appointment within 15 days after the receipt by it of a written request so to do, the Trustee shall have the power to make such appointment without the Depositor.

(c) No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor Trustee under Section 9.06 hereunder and no notice to

Certificateholders of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 9.08 hereof.

(d) In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 9.11, all rights, powers, duties and obligations conferred or imposed upon the Trustee and required to be conferred on such co-trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly, 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 Trust or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee.

(e) Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, 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 IX. 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.

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

(a) For federal income tax purposes, the taxable year of each 2006-1 REMIC shall be a calendar year and the Securities Administrator shall maintain or cause the maintenance of the books of each such 2006-1 REMIC on the accrual method of accounting.

(b) The Securities Administrator shall prepare and file or cause to be filed with the Internal Revenue Service, and the Trustee shall upon the written instruction of the Securities Administrator sign, Federal tax information returns or elections required to be made hereunder with respect to each 2006-1 REMIC, the Trust Fund, if applicable, and the Certificates containing such information and at the times and in the manner as may be required by the Code or applicable Treasury regulations, and the Securities Administrator shall furnish to each Holder of Certificates at any time during the calendar year for which such returns or reports are made

152

such statements or information at the times and in the manner as may be required thereby, including, without limitation, reports relating to mortgaged property that is abandoned or foreclosed, receipt of mortgage interests in kind in a trade or business, a cancellation of indebtedness, interest, original issue discount and market discount or premium (using a constant prepayment assumption of 30% CPR for the Group I Mortgage Loans and 25% CPR for the Group II Mortgage Loans). The Securities Administrator will apply for an Employee Identification Number from the IRS under Form SS-4 or any other acceptable method for all tax entities. In connection with the foregoing, the Securities Administrator shall timely prepare and file, and the Trustee shall upon the written instruction of the Securities Administrator sign, IRS Form 8811, which shall provide the name and address of the person who can be contacted to obtain information required to be reported to the holders of regular interests in each 2006-1 REMIC (the “REMIC Reporting Agent”). The Trustee shall make elections to treat each 2006-1 REMIC as a REMIC (which elections shall apply to the taxable period ending December 31, 2006 and each calendar year thereafter) in such manner as the Code or applicable Treasury regulations may prescribe, and as described by the Securities Administrator. The Trustee shall upon the written instruction of the Securities Administrator sign all tax information returns filed pursuant to this Section and any other returns as may be required by the Code. The Holder of the largest percentage interest in the Residual Certificates is hereby designated as the “Tax Matters Person” (within the meaning of Treas. Reg. §§1.860F-4(d)) for each 2006-1 REMIC. The Securities Administrator is hereby designated and appointed as the agent of each such Tax Matters Person. Any Holder of a Residual Certificate will by acceptance thereof appoint the Securities Administrator as agent and attorney-in-fact for the purpose of acting as Tax Matters Person for each 2006-1 REMIC during such time as the Securities Administrator does not own any such Residual Certificate. In the event that the Code or applicable Treasury regulations prohibit the Trustee from signing tax or information returns or other statements, or the Securities Administrator from acting as agent for the Tax Matters Person, the Trustee and the Securities Administrator shall take whatever action that in their sole good faith judgment is necessary for the proper filing of such information returns or for the provision of a tax matters person, including designation of the Holder of the largest percentage interest in a Residual Certificate to sign such returns or act as tax matters person. Each Holder of a Residual Certificate shall be bound by this Section.

(c) The Securities Administrator shall provide upon request and receipt of reasonable compensation, such information as required in Section 860D(a)(6)(B) of the Code to the Internal Revenue Service, to any Person purporting to transfer a Residual Certificate to a Person other than a transferee permitted by Section 5.05(b), and to any regulated investment company, real estate investment trust, common trust fund, partnership, trust, estate, organization described in Section 1381 of the Code, or nominee holding an interest in a pass-through entity described in Section 860E(e)(6) of the Code, any record holder of which is not a transferee permitted by Section 5.05(b) (or which is deemed by statute to be an entity with a disqualified member).

(d) The Securities Administrator shall prepare and file or cause to be filed, and the Trustee shall upon the written instruction of the Securities Administrator sign, any state income tax returns required under Applicable State Law with respect to each REMIC or the Trust Fund.

(e) Notwithstanding any other provision of this Agreement, the Securities Administrator shall comply with all federal withholding requirements respecting payments to

153

Certificateholders of interest or original issue discount on the Mortgage Loans, that the Securities Administrator reasonably believes are applicable under the Code. The consent of Certificateholders shall not be required for such withholding. In the event the Securities Administrator withholds any amount from interest or original issue discount payments or advances thereof to any Certificateholder pursuant to federal withholding requirements, the Securities Administrator shall, together with its monthly report to such Certificateholders, indicate such amount withheld.

(f) The Trustee and the Securities Administrator agree to indemnify the Trust Fund and the Depositor for any taxes and costs including, without limitation, any reasonable attorneys fees imposed on or incurred by the Trust Fund, the Depositor or the Master Servicer, as a result of a breach of the Trustee’s covenants and the Securities Administrator’s covenants, respectively, set forth in this Section 9.12; provided, however, such liability and obligation to indemnify in this paragraph shall be several and not joint and neither the Trustee nor the Securities Administrator shall be liable or be obligated to indemnify the Trust Fund for the failure by the other to perform any duty under this Agreement or the breach by the other of any covenant in this Agreement.

Section 10.01. Termination Upon Repurchase by EMC or its Designee or Liquidation of the Mortgage Loans. (a) Subject to Section 10.02, the respective obligations and responsibilities of the Depositor, the Trustee, the Master Servicer and the Securities Administrator created hereby, other than the obligation of the Securities Administrator to make payments to Certificateholders as set forth in this Section 10.01 shall terminate:

(i) in accordance with Section 10.01(c), the repurchase by or at the direction of EMC or its designee of all of the Mortgage Loans in each of Loan Group I and Loan Group II (which repurchase of the Group I Mortgage Loans and the Group II Mortgage Loans may occur on separate dates) and all related REO Property remaining in the Trust at a price (the “Termination Purchase Price”) equal to the sum of (without duplication) (a) 100% of the Outstanding Principal Balance of each Mortgage Loan in such Loan Group (other than a Mortgage Loan related to REO Property) as of the date of repurchase, net of the principal portion of any unreimbursed Monthly Advances on the Mortgage Loans relating to the Mortgage Loans made by the purchaser, plus accrued but unpaid interest thereon at the applicable Mortgage Interest Rate to, but not including, the first day of the month of repurchase, (b) the appraised value of any related REO Property, less the good faith estimate of the Depositor of liquidation expenses to be incurred in connection with its disposal thereof (but not more than the Outstanding Principal Balance of the related Mortgage Loan, together with interest at the applicable Mortgage Interest Rate accrued on that balance but unpaid to, but not including, the first day of the month of repurchase), such appraisal to be calculated by an appraiser mutually agreed upon by the Depositor and the Trustee at the expense of the Depositor, (c) unreimbursed out-of pocket costs of the Master Servicer, including unreimbursed servicing advances and the principal portion of any unreimbursed Monthly Advances, made on the Mortgage Loans in such Loan Group prior to the exercise of such repurchase right, (d) any costs and damages incurred by the Trust in connection with any violation of any predatory or abusive lending laws with respect to a Mortgage Loan, and (e) any unreimbursed costs and expenses of the Trustee and the Securities Administrator payable pursuant to Section 9.05;

(ii) the later of the making of the final payment 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 acquired with respect to any Mortgage Loan; provided, however, that in the event that an advance has been made, but not yet recovered, at the time of such termination, the Person having made such advance shall be entitled to receive, notwithstanding such termination, any payments received subsequent thereto with respect to which such advance was made; or

(iii) the payment to the Certificateholders of all amounts required to be paid to them pursuant to this Agreement.

(b) In no event, however, shall the Trust created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James’s, living on the date of this Agreement.

155

(c) (i) The right of EMC or its designee to repurchase Group I Mortgage Loans and related assets described in Section 10.01(a)(i) above shall be exercisable only if the aggregate Stated Principal Balance of the Mortgage Loans at the time of any such repurchase is less than 20% of the sum of the Cut-off Date Balance.

(i) The right of EMC or its designee to repurchase Group II Mortgage Loans and related assets described in Section 10.01(a)(i) above shall be exercisable only if the aggregate Stated Principal Balance of the Mortgage Loans at the time of any such repurchase is less than 10% of the sum of the Cut-off Date Balance.

(iii) The right of EMC or its designee to repurchase all the assets of the Trust Fund described in Section 10.01(a)(i) above shall also be exercisable if the Depositor, based upon an Opinion of Counsel addressed to the Depositor, the Trustee and the Securities Administrator has determined that the REMIC status of any 2006-1 REMIC has been lost or that a substantial risk exists that such REMIC status will be lost for the then-current taxable year.

(iv) At any time thereafter, in the case of (i) and (ii) or (iii) above, EMC may elect to terminate any 2006-1 REMIC at any time, and upon such election, the Depositor or its designee, shall purchase in accordance with Section 10.01(a)(i) above all the assets of the Trust Fund.

(d) The Securities Administrator shall give notice of any termination to the Certificateholders, with a copy to the Master Servicer and the Trustee (who shall then give such copy of notice to the Rating Agencies) upon which the Certificateholders shall surrender their Certificates to the Securities Administrator for payment of the final distribution and cancellation. Such notice shall be given by letter, mailed not earlier than the l5th day and not later than the 25th day of the month next preceding the month of such final distribution, and shall specify (i) the Distribution Date upon which final payment of the Certificates will be made upon presentation and surrender of the Certificates at the Corporate Trust Office of the Securities Administrator therein designated, (ii) the amount of any such final payment and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the Corporate Trust Office of the Securities Administrator therein specified.

(e) If the option of EMC to repurchase or cause the repurchase of all Group I Mortgage Loans or the Group II Mortgage Loans and the related assets described in Section 10.01(c) above is exercised, EMC and/or its designee shall deliver to the Securities Administrator for deposit in the Distribution Account, by the Business Day prior to the applicable Distribution Date, an amount equal to the Termination Purchase Price of the Mortgage Loans being repurchased on such Distribution Date. Upon presentation and surrender of the related Certificates by the related Certificateholders, the Securities Administrator shall distribute to such Certificateholders from amounts then on deposit in the Distribution Account an amount determined as follows: with respect to each such Certificate (other than the Class II-X Certificates, the Residual Certificates and the Class XP Certificates), the outstanding Certificate Principal Balance, plus with respect to each such Certificate (other than the Residual Certificates and the Class XP Certificates), one month’s interest thereon at the applicable Pass-Through Rate; and with respect to the Class R Certificates and the Class XP Certificates, the percentage interest

156

evidenced thereby multiplied by the difference, if any, between the above described repurchase price and the aggregate amount to be distributed to the Holders of the related Certificates (other than the Residual Certificates and the Class XP Certificates). If the amounts then on deposit in the Distribution Account are not sufficient to pay all of the related Certificates in full (other than the Residual Certificates and the Class XP Certificates), any such deficiency will be allocated in the case of a repurchase of the Group I Mortgage Loans, first, to the Class I-B Certificates, in inverse order of their numerical designation, second, to the Class I-M Certificates, in inverse order of their numerical designation, and then to the related Senior Certificates, on a pro rata basis and in the case of a repurchase of the Group II Mortgage Loans, first, to the Class II-B Certificates, in inverse order of their numerical designation, and then to the related Senior Certificates, on a pro rata basis. Upon deposit of the required repurchase price and following such final Distribution Date for the related Certificates, the Trustee shall release promptly (or cause the Custodian to release) to EMC and/or its designee the Mortgage Files for the remaining applicable Mortgage Loans, and the Accounts with respect thereto shall terminate, subject to the Securities Administrator’s obligation to hold any amounts payable to the related Certificateholders in trust without interest pending final distributions pursuant to Section 10.01(g). After final distributions pursuant to Section 10.01(g) to all Certificateholders, any other amounts remaining in the Accounts will belong to the Depositor.

(f) In the event that this Agreement is terminated by reason of the payment or liquidation of all Mortgage Loans or the disposition of all property acquired with respect to all Mortgage Loans under Section 10.01(a)(ii) above, upon the presentation and surrender of the Certificates, the Securities Administrator shall distribute to the remaining Certificateholders, in accordance with their respective interests, all distributable amounts remaining in the Distribution Account. Following such final Distribution Date, the Trustee shall release (or shall instruct the Custodian, as its agent, to release) promptly to the Depositor or its designee the Mortgage Files for the remaining Mortgage Loans, and the Distribution Account shall terminate, subject to the Securities Administrator’s obligation to hold any amounts payable to the Certificateholders in trust without interest pending final distributions pursuant to this Section 10.01(f).

(g) If not all of the Certificateholders shall surrender their Certificates for cancellation within six months after the time specified in the above-mentioned written notice, the Securities Administrator 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, not all the Certificates shall have been surrendered for cancellation, the Securities Administrator may take appropriate steps, or appoint any 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 subject to this Agreement.

(h) EMC, if it is not the Master Servicer, or its designee, as applicable, shall be deemed to represent that one of the following will be true and correct: (i) the exercise of the optional termination right set forth in Section 10.01 shall not result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code or (ii) EMC or such designee, as applicable, is (A) not a party in interest with respect to any Plan and (B) is not a "benefit plan investor" (other than a plan sponsored or maintained by EMC or the designee, as the case may be, provided that no assets of such plan are invested or deemed to be invested in the Certificates).

157

If the holder of the optional termination right is unable to exercise such option by reason of the preceding sentence, then the Master Servicer may exercise such option.

Section 10.02. Additional Termination Requirements. (a) If the option of the Depositor to repurchase all the Mortgage Loans under Section 10.01(a)(i) above is exercised, the Trust Fund and each 2006-1 REMIC shall be terminated in accordance with the following additional requirements, unless the Trustee has been furnished with an Opinion of Counsel addressed to the Trustee to the effect that the failure of the Trust to comply with the requirements of this Section 10.02 will not (i) result in the imposition of taxes on “prohibited transactions” as defined in Section 860F of the Code on each 2006-1 REMIC or (ii) cause any 2006-1 REMIC to fail to qualify as a 2006-1 REMIC at any time that any Regular Certificates are outstanding:

(i) within 90 days prior to the final Distribution Date, at the written direction of Depositor, the Securities Administrator, as agent for the respective Tax Matters Persons, shall adopt a plan of complete liquidation of each 2006-1 REMIC in the case of a termination under Section 10.01(a)(i). Such plan, which shall be provided to the Securities Administrator by the Depositor, shall meet the requirements of a “qualified liquidation” under Section 860F of the Code and any regulations thereunder.

(ii) the Depositor shall notify the Trustee and the Securities Administrator at the commencement of such 90-day liquidation period and, at or prior to the time of making of the final payment on the Certificates, the Securities Administrator shall sell or otherwise dispose of all of the remaining assets of the Trust Fund in accordance with the terms hereof; and

(iii) at or after the time of adoption of such a plan of complete liquidation of any 2006-1 REMIC and at or prior to the final Distribution Date, the Securities Administrator shall sell for cash all of the assets of the Trust to or at the direction of the Depositor, and each 2006-1 REMIC, shall terminate at such time.

(b) By their acceptance of the Residual Certificates, the Holders thereof hereby (i) agree to adopt such a plan of complete liquidation of the related 2006-1 REMIC upon the written request of the Depositor, and to take such action in connection therewith as may be reasonably requested by the Depositor and (ii) appoint the Depositor as their attorney-in-fact, with full power of substitution, for purposes of adopting such a plan of complete liquidation. The Trustee shall adopt such plan of liquidation by filing the appropriate statement on the final tax return of each 2006-1 REMIC. Upon complete liquidation or final distribution of all of the assets of the Trust Fund, the Trust Fund and each 2006-1 REMIC shall terminate.

ARTICLE XI

Miscellaneous Provisions

Section 11.01. Intent of Parties. The parties intend that each 2006-1 REMIC shall be treated as a REMIC for federal income tax purposes and that the provisions of this Agreement should be construed in furtherance of this intent. Notwithstanding any other express or implied agreement to the contrary, the Seller, the Master Servicer, the Securities Administrator, the Depositor, the Trustee, each recipient of the related Prospectus Supplement and, by its acceptance thereof, each holder of a Certificate, agrees and acknowledges that each party hereto has agreed that each of them and their employees, representatives and other agents may disclose, immediately upon commencement of discussions, to any and all persons the tax treatment and tax structure of the Certificates and the 2006-1 REMICs, the transactions described herein and all materials of any kind (including opinions and other tax analyses) that are provided to any of them relating to such tax treatment and tax structure except where confidentiality is reasonably necessary to comply with the securities laws of any applicable jurisdiction. For purposes of this paragraph, the terms “tax treatment” and “tax structure” have the meanings set forth in Treasury Regulation Sections 1.6011-4(c), 301.6111-2(c) and 301.6112-1(d).

Section 11.02. Amendment. (a) This Agreement may be amended from time to time by the Company, the Depositor, the Master Servicer, the Securities Administrator and the Trustee, without notice to or the consent of any of the Certificateholders, to (i) cure any ambiguity, (ii) correct or supplement any provisions herein that may be defective or inconsistent with any other provisions herein, (iii) conform any provisions herein to the provisions in the Prospectus, (iv) comply with any changes in the Code or (v) make any other provisions with respect to matters or questions arising under this Agreement which shall not be inconsistent with the provisions of this Agreement; provided, however, that with respect to clauses (iv) and (v) of this Section 11.02(a), such action shall not, as evidenced by an Opinion of Independent Counsel, addressed to the Trustee, adversely affect in any material respect the interests of any Certificateholder. Notwithstanding anything contained in Section 3.23, this Agreement shall not be amended without the agreement of all the parties hereto.

(b) This Agreement may also be amended from time to time by the Company, the Master Servicer, the Depositor, the Securities Administrator and the Trustee, with the consent of the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund or of the applicable Class or Classes, if such amendment affects only such Class or Classes, 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 Certificateholders; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments received on Mortgage Loans which are required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) reduce the aforesaid percentage of Certificates the Holders of which are required to consent to any such amendment, without the consent of the Holders of all Certificates then outstanding, or (iii) cause any 2006-1 REMIC to fail to qualify as a REMIC for federal income tax purposes, as evidenced by an Opinion of Independent Counsel addressed to the Trustee which shall be provided to the Trustee other than at the Trustee’s expense. Notwithstanding any other provision of this Agreement, for purposes of the giving or withholding of consents pursuant to this Section 11.02(b), Certificates registered in the name of or held for the benefit of

159

the Depositor, the Securities Administrator, the Master Servicer, or the Trustee or any Affiliate thereof shall be entitled to vote their Fractional Undivided Interests with respect to matters affecting such Certificates.

(c) Promptly after the execution of any such amendment, the Securities Administrator shall furnish a copy of such amendment or written notification of the substance of such amendment to each Certificateholder and the Trustee, and the Trustee shall then provide a copy of such amendment or notice to the Rating Agencies.

(d) In the case of an amendment under Section 11.02(b) above, it shall not be necessary for the Certificateholders to approve the particular form of such an amendment. Rather, it shall be sufficient if the Certificateholders approve the substance of the amendment. 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 Securities Administrator may prescribe.

(e) Prior to the execution of any amendment to this Agreement, the Trustee and the Securities Administrator shall be entitled to receive and rely upon an Opinion of Counsel addressed to the Trustee and the Securities Administrator stating that the execution of such amendment is authorized or permitted by this Agreement. The Trustee and the Securities Administrator may, but shall not be obligated to, enter into any such amendment which affects the Trustee’s or the Securities Administrator’s own respective rights, duties or immunities under this Agreement.

Section 11.03. Recordation of Agreement. To the extent permitted by applicable law, this Agreement is subject to recordation in all appropriate public offices for real property records in all the counties or other comparable jurisdictions in which any or all of the Mortgaged Properties are situated, and in any other appropriate public recording office or elsewhere. The Depositor shall effect such recordation, at the expense of the Trust upon the request in writing of a Certificateholder, but only if such direction is accompanied by an Opinion of Counsel (provided at the expense of the Certificateholder requesting recordation) to the effect that such recordation would materially and beneficially affect the interests of the Certificateholders or is required by law.

Section 11.04. Limitation on Rights of Certificateholders. (a) The death or incapacity of any Certificateholder shall not terminate this Agreement or the Trust, nor entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of the Trust, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

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

160

(c) No Certificateholder shall have any right by virtue of any provision of this Agreement to institute any suit, action or proceeding in equity or at law upon, under or with respect to this Agreement against the Depositor, the Securities Administrator, the Master Servicer or any successor to any such parties unless (i) such Certificateholder previously shall have given to the Securities Administrator a written notice of a continuing default, as herein provided, (ii) the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs and expenses and liabilities to be incurred therein or thereby, and (iii) the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding.

(d) No one or more Certificateholders shall have any right by virtue of any provision of this Agreement to affect the rights of any other Certificateholders or to obtain or seek to obtain priority or preference over any other such Certificateholder, or to enforce any right under this Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 11.04, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 11.05. Acts of Certificateholders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by Certificateholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Certificateholders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Securities Administrator and, where it is expressly required, to the Depositor. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement and conclusive in favor of the Securities Administrator and the Depositor, if made in the manner provided in this Section 11.05.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his or her individual capacity, such certificate or affidavit shall also constitute sufficient proof of his or her authority. The fact and date of the execution of any such instrument or writing, or the authority of the individual executing the same, may also be proved in any other manner which the Securities Administrator deems sufficient.

(c) The ownership of Certificates (notwithstanding any notation of ownership or other writing on such Certificates, except an endorsement in accordance with Section 5.02 made on a Certificate presented in accordance with Section 5.04) shall be proved by the Certificate Register, and neither the Trustee, the Securities Administrator, the Depositor, the Master Servicer nor any successor to any such parties shall be affected by any notice to the contrary.

161

(e) Any request, demand, authorization, direction, notice, consent, waiver or other action of the holder of any Certificate shall bind every future holder of the same Certificate and the holder of every Certificate issued upon the registration of transfer or exchange thereof, if applicable, or in lieu thereof with respect to anything done, omitted or suffered to be done by the Trustee, the Securities Administrator, the Depositor, the Master Servicer or any successor to any such party in reliance thereon, whether or not notation of such action is made upon such Certificates.

(e) In determining whether the Holders of the requisite percentage of Certificates evidencing Fractional Undivided Interests have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Certificates owned by the Trustee, the Securities Administrator, the Depositor, the Master Servicer or any Affiliate thereof shall be disregarded, except as otherwise provided in Section 11.02(b) and except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Certificates which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Certificates which have been pledged in good faith to the Trustee, the Securities Administrator, the Depositor, the Master Servicer or any Affiliate thereof may be regarded as outstanding if the pledgor establishes to the satisfaction of the Trustee the pledgor’s right to act with respect to such Certificates and that the pledgor is not an Affiliate of the Trustee, the Securities Administrator, the Depositor, or the Master Servicer, as the case may be.

Section 11.06. Governing Law. THIS AGREEMENT AND THE CERTIFICATES SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO ITS CONFLICT OF LAWS RULES (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW, WHICH THE PARTIES HERETO EXPRESSLY RELY UPON IN THE CHOICE OF SUCH LAW AS THE GOVERNING LAW HEREUNDER) AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.
