ARTICLE I

Definitions

Whenever used in this Agreement, the following words and phrases, unless otherwise expressly provided or unless the context otherwise requires, shall have the meanings specified in this Article.

Accepted Servicing Practices: With respect to any Mortgage Loan, as applicable, those customary mortgage servicing practices, including prudent collection and loan administration procedures, of prudent mortgage servicing institutions that service mortgage loans of the same type and quality as such Mortgage Loan in the jurisdiction where the related Mortgaged Property is located, to the extent applicable to the Servicer.

Account: The Custodial Account, the Distribution Account, the Pre-Funding Account, the Pre-Funding Reserve Account, the Interest Coverage Account, the Class XP Reserve Account or the Class A Reserve Fund as the context may require.

Accrued Certificate Interest: With respect to the Certificates of any Class (other than the Class R Certificates and the Class XP Certificates) on any Distribution Date, is equal to the amount of interest accrued during the related Interest Accrual Period at the applicable Pass-Through Rate on the Current Principal Amount or Notional Amount, as applicable, of such Certificate immediately prior to such Distribution Date, less (1) in the case of a Senior Certificate, such Certificate’s share of (a) Prepayment Interest Shortfalls on the related Mortgage Loans, to the extent not covered by Compensating Interest Payments paid by the Servicer, (b) interest shortfalls on the related Mortgage Loans resulting from the application of the Relief Act or similar state law, (c) after the applicable Cross-Over Date, the interest portion of any Realized Losses on the related Mortgage Loans, in each case, allocated thereto in accordance with Section 6.02(g) and (d) any shortfalls resulting from Net Deferred Interest on Mortgage Loans in the related Loan Group allocated thereto in accordance with Section 6.01(e), (2) in the case of a Subordinate Certificate, such Certificate’s share of (a) Prepayment Interest Shortfalls on the Mortgage Loans in each Loan Group, to the extent not covered by Compensating Interest Payment paid by the Servicer, (b) interest shortfalls on the Mortgage Loans in each Loan Group resulting from the application of the Relief Act or similar state law, (c) the interest portion of any Realized Losses on the Mortgage Loans in each Loan Group allocated thereto in accordance with Section 6.02(g) and (d) any shortfalls resulting from Net Deferred Interest on the Mortgage Loans in each Loan Group allocated thereto in accordance with Section 6.01(e), and (3) in the case of the Class X Certificates, the Accrued Certificate Interest for each Class on any Distribution Date will be reduced by the amount of any Carryover Shortfall Amount for the Class A Certificates (in the case of the Senior Class X Certificates) and any Carryover Shortfall Amount for the Class M Certificates and the Class B Certificates (in the case of the Class M-X Certificates). Accrued Certificate Interest is calculated on the basis of (i) a 360-day year consisting of twelve 30-day months for the Class III-A Certificates and the Class X Certificates and (ii) a 360-day year and the actual number of days elapsed in the Interest Accrual Period for the Class A (other than the Class III-A Certificates), Class M and Class B Certificates. No Accrued Certificate Interest will be payable with respect to any Class of Certificates if the outstanding Current Principal Amount of such Certificate (other than the Class X Certificates) has been reduced to zero.

Affiliate: As to any Person, any other Person controlling, controlled by or under common control with such Person. “Control” means the power to direct the management and policies of a Person, directly or indirectly, whether through ownership of voting securities, by contract or otherwise. “Controlled” and “Controlling” have meanings correlative to the foregoing. The Trustee may conclusively presume that a Person is not an Affiliate of another Person unless a Responsible Officer of the Trustee has actual knowledge to the contrary.

Agreement: This Pooling and Servicing Agreement and all amendments hereof and supplements hereto.

Allocable Share: With respect to any Class of Subordinate Certificates and any Distribution Date, an amount equal to the product of (i) the Subordinate Optimal Principal Amount after giving effect to the reduction of the Current Principal Amount of the Class M-X Certificates on such Distribution Date and (ii) the fraction, the numerator of which is the Current Principal Amount of such Class and the denominator of which is the aggregate Current Principal Amount of all Classes of the Subordinate Certificates; provided, however, that no Class of Subordinate Certificates (other than the outstanding Class M Certificates or if no Class M Certificates are outstanding, the Class of Class B Certificates with the lowest numerical designation) shall be entitled on any Distribution Date to receive distributions pursuant to clauses (ii), (iii) and (v) of the definition of Subordinate Optimal Principal Amount unless the related Class Prepayment Distribution Trigger for such Distribution Date has been satisfied (any amount distributable pursuant to clauses (ii), (iii) and (v) of the definition of Subordinate Optimal Principal Amount shall be distributed among the Classes entitled thereto, pro rata based on their respective Current Principal Amounts); provided, further, that if on a Distribution Date, the Current Principal Amount of any Class of Subordinate Certificates for which the related Class Prepayment Distribution Trigger has been satisfied is reduced to zero, such Class’s remaining Allocable Share shall be distributed to the remaining Classes of Subordinate Certificates which satisfy the related Class Prepayment Distribution Trigger in reduction of their respective Current Principal Amounts, sequentially, first to the Class M Certificates and then to the Class B Certificates, in each case, in the order of their numerical Class designations.

Applicable Credit Rating: For any long-term deposit or security, a credit rating of AAA in the case of S&P or Aaa in the case of Moody’s (or with respect to investments in money market funds, a credit rating of “AAAm” or “AAAm-G” in the case of S&P and the highest rating given by Moody’s for money market funds in the case of Moody’s). For any short-term deposit or security, or a rating of A-l+ in the case of S&P or Prime-1 in the case of Moody’s.

Applicable State Law: For purposes of Section 9.12(d), the Applicable State Law shall be (a) the law of the State of New York and (b) such other state law whose applicability shall have been brought to the attention of the Trustee by either (i) an Opinion of Counsel reasonably acceptable to the Trustee delivered to it by the Servicer or the Depositor, or (ii) written notice from the appropriate taxing authority as to the applicability of such state law.

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 or the Subsequent Transfer Instruments, as applicable, 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 due and principal received with respect to the Initial Mortgage Loans after the Cut-off Date and the Subsequent Mortgage Loans after the related Subsequent Cut-Off Date, as the case may be, but excluding any payments of 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 Custodial Account, (iii) such assets relating to the Mortgage Loans as from time to time may be held by the Trustee in the Distribution Account, (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 any Subsequent Mortgage Loan Purchase Agreements to the extent provided in Section 2.03(a), (vii) the Class R Deposit, (viii) such assets as shall from time to time be credited or are required by the terms of this Agreement to be credited to any of the Accounts 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 “Wells Fargo 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 Custodial 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 or the Subsequent Transfer Date, as applicable, 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 (on behalf of the Trust) acknowledges the sale, transfer and assignment of the Trust Fund to it 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 will continue to hold those documents and any amendments, replacements or supplements thereto and all other assets of the Trust Fund delivered to it 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 a Subsequent Transfer Date, with respect to any Subsequent Mortgage Loans, the Custodian, 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 a Subsequent Transfer Date, with respect to any 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, as the case may be, 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 a 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 the 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 a Subsequent Transfer Date, with respect to any 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 a Subsequent Mortgage Loan Purchase Agreement, as the case may be, 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 a Subsequent Mortgage Loan Purchase Agreement, as the case may be, 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 the 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 Servicer the Repurchase Price for deposit in the Custodial Account and the Seller shall provide to the Trustee written notification detailing the components of the Repurchase Price. Upon deposit of the Repurchase Price in the Custodial 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 Trustee. The 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 Servicer, to reflect such repurchase and shall promptly notify the Trustee of such amendment and the Trustee shall promptly notify the Rating Agencies and the Servicer 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 Trust for the benefit of the Certificateholders, all of its right, title and interest in the Mortgage Loan Purchase Agreement and any Subsequent Mortgage Loan Purchase Agreement. 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 Trust 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 Servicer or the Trustee discovers a breach of any of the representations and warranties set forth in the Mortgage Loan Purchase Agreement or any Subsequent Mortgage Loan Purchase Agreement, as the case may be, 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, the applicable 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 Trust; provided, however, that if there is a breach of any representation set forth in the Mortgage Loan Purchase Agreement, a Subsequent 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 Servicer for deposit in the Custodial 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 Trustee. The Trustee shall amend the Mortgage Loan Schedule to reflect such repurchase and shall promptly notify 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, a 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 (on behalf of the Trust) 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, any Subsequent Mortgage Loan Purchase

Agreement or this Agreement, as applicable; provided, however, that substitution pursuant to the Mortgage Loan Purchase Agreement, any 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 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 Trustee 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, any 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, any 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, any 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 any 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 (on behalf of the Trust). The 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, who shall then deliver such amended Mortgage Loan Schedule to the Rating Agencies.

Section 2.05

Issuance of Certificates.

(a) The Trustee acknowledges the assignment to it (on behalf of the Trust) 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 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 the REMIC I Regular Interests, and the other assets of REMIC II for the benefit of the holders of the REMIC II Certificates. The Trustee acknowledges receipt of the REMIC I Regular Interests (which are uncertificated) and the other assets of REMIC II and declares that it holds and will hold the same in trust for the exclusive use and benefit of the holders of the REMIC II Certificates.

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

ARTICLE III

Administration and Servicing of Mortgage Loans

Section 3.01 Servicer to Act as Servicer. The Servicer shall service and administer the Mortgage Loans in accordance with this Agreement and with Accepted Servicing Practices and shall have full power and authority, acting alone, to do or cause to be done any and all things in connection with such servicing and administration which the Servicer may deem necessary or desirable and consistent with the terms of this Agreement and with Accepted Servicing Practices and shall exercise the same care that it customarily employs for its own account. Except as set forth in this Agreement, the Servicer shall service the Mortgage Loans in accordance with Accepted Servicing Practices in compliance with the servicing provisions of the Fannie Mae Guide, which include, but are not limited to, provisions regarding the liquidation of Mortgage Loans, the collection of Mortgage Loan payments, the payment of taxes, insurance and other charges, the maintenance of hazard insurance with a Qualified Insurer, the maintenance of fidelity bond and errors and omissions insurance, inspections, the restoration of Mortgaged Property, the maintenance of Primary Mortgage Insurance Policies, insurance claims, and title insurance, management of REO Property, permitted withdrawals with respect to REO Property, liquidation reports, and reports of foreclosures and abandonments of Mortgaged Property, the transfer of Mortgaged Property, the release of Mortgage Loan Documents, annual statements, and examination of records and facilities. In the event of any conflict, inconsistency or discrepancy between any of the servicing provisions of this Agreement and any of the servicing provisions of the Fannie Mae Guide, the provisions of this Agreement shall control and be binding upon the Depositor and the Servicer.

Consistent with the terms of this Agreement, the Servicer may waive, modify or vary any term of any Mortgage Loan or consent to the postponement of any such term or in any manner grant indulgence to any Mortgagor if in the Servicer's reasonable and prudent determination such waiver, modification, postponement or indulgence is not materially adverse to the Certificateholders, provided, however, the Servicer shall not permit any modification with respect to any Mortgage Loan that would change the Mortgage Interest Rate, forgive the payment of principal or interest (unless in connection with the liquidation of the related Mortgage Loan or except in connection with prepayments to the extent that such reamortization is not inconsistent with the terms of the Mortgage Loan), or extend the final maturity date of such Mortgage Loan, unless such Mortgage Loan is in default or, in the judgment of the Servicer, such default is reasonably foreseeable or waive a prepayment penalty or charge, without the written consent of the Depositor and, provided, further, that no such modification shall reduce the interest rate on a Mortgage Loan below the Servicing Fee Rate. Without limiting the generality of the foregoing, the Servicer shall continue, and is hereby authorized and empowered, to prepare, execute and deliver, all instruments of satisfaction or cancellation, or of partial or full release, discharge and all other comparable instruments, with respect to the Mortgage Loans and with respect to the Mortgaged Properties.

The Servicer shall provide to each Mortgagor of a Mortgage Loan all payment options listed in the related Mortgage Note that are available to such Mortgagor with respect to such payment, notwithstanding any provision in the related Mortgage Note that explicitly states or

implies that providing such options is optional for the servicer of such Mortgage Loan or the owner or holder of the related Mortgage Note.

Notwithstanding the foregoing, the Servicer shall not permit any modification with respect to any Mortgage Loan that would both constitute a sale or exchange of such Mortgage Loan within the meaning of Section 1001 of the Code and any proposed, temporary or final regulations promulgated thereunder (other than in connection with a proposed conveyance or assumption of such Mortgage Loan that is treated as a Principal Prepayment in Full) and cause any REMIC formed under this Agreement to fail to qualify as a REMIC under the Code. Upon request, the Trustee shall furnish the Servicer with any powers of attorney, in substantially the form attached hereto as Exhibit I, and other documents in form as provided to it necessary or appropriate to enable the 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 any court pleadings, requests for trustee’s sale or other documents prepared by the Servicer as 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 2005-AR4 REMIC shall exist, the Trustee shall act in accordance herewith to assure continuing treatment of such 2005-AR4 REMIC as a REMIC, and the Trustee shall comply with any directions of the Depositor or the 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, any Subsequent Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, accept any contribution to any 2005-AR4 REMIC after the Startup Day without receipt of a REMIC Opinion addressed to the Trustee.

Section 3.03 Monitoring of Subservicers. (a) The Servicer shall perform all of its servicing responsibilities hereunder or may cause a subservicer to perform any such servicing responsibilities on its behalf, but the use by the Servicer of a subservicer shall not release the Servicer from any of its obligations hereunder and the Servicer shall remain responsible

hereunder for all acts and omissions of each subservicer as fully as if such acts and omissions were those of the Servicer. Any such subservicer must be a Fannie Mae approved seller/servicer or a Freddie Mac seller/servicer in good standing and no event shall have occurred, including but not limited to, a change in insurance coverage, which would make it unable to comply with the eligibility requirements for lenders imposed by Fannie Mae or for seller/servicers by Freddie Mac, or which would require notification to Fannie Mae or Freddie Mac. The Servicer shall pay all fees and expenses of each subservicer from its own funds, and a subservicer's fee shall not exceed the Servicing Fee.

(b) At the cost and expense of the Servicer, without any right of reimbursement from the Custodial Account, the Servicer shall be entitled to terminate the rights and responsibilities of a subservicer and arrange for any servicing responsibilities to be performed by a successor subservicer meeting the requirements in the preceding paragraph, provided, however, that nothing contained herein shall be deemed to prevent or prohibit the Servicer, at the Servicer's option, from electing to service the related Mortgage Loans itself. In the event that the Servicer's responsibilities and duties under this Agreement are terminated pursuant to Section 7.07, 8.01 or 10.01, and if requested to do so by the Depositor, the Servicer shall at its own cost and expense terminate the rights and responsibilities of each subservicer effective as of the date of termination of the Servicer. The Servicer shall pay all fees, expenses or penalties necessary in order to terminate the rights and responsibilities of each subservicer from the Servicer's own funds without reimbursement from the Depositor.

(c)Notwithstanding any of the provisions of this Agreement relating to agreements or arrangements between the Servicer and a subservicer or any reference herein to actions taken through a subservicer or otherwise, the Servicer shall not be relieved of its obligations to the Depositor and shall be obligated to the same extent and under the same terms and conditions as if it alone were servicing and administering the Mortgage Loans. The Servicer shall be entitled to enter into an agreement with a subservicer for indemnification of the Servicer by the subservicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

(d)Any subservicing agreement and any other transactions or services relating to the Mortgage Loans involving a subservicer shall be deemed to be between such subservicer and Servicer alone, and the Depositor shall have no obligations, duties or liabilities with respect to such Subservicer including no obligation, duty or liability of Depositor to pay such subservicer's fees and expenses. For purposes of distributions and advances by the Servicer pursuant to this Agreement, the Servicer shall be deemed to have received a payment on a Mortgage Loan when a subservicer has received such payment.

Section 3.04 Fidelity Bond. The 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 the Servicer’s behalf, and covering errors and omissions in the performance of the 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 servicers.

Section 3.05 Power to Act; Procedures. The Servicer shall 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 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, as applicable; provided, however, that the Servicer shall not (and consistent with its responsibilities under 3.03, shall not permit any subservicer 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 2005-AR4 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 Servicer has received an Opinion of Counsel (but not at the expense of the Servicer) to the effect that the contemplated action would not cause any 2005-AR4 REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon any 2005-AR4 REMIC. The Trustee shall furnish the Servicer, upon written request from a Servicing Officer, with any powers of attorney empowering the 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 this Agreement, and the Trustee shall execute and deliver such other documents, as the Servicer may request, to enable the Servicer to service and administer the Mortgage Loans and carry out its duties hereunder, in each case in accordance with Accepted Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Servicer). If the 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 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 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.

(a) When any Mortgaged Property is conveyed by a Mortgagor, the Servicer or subservicer, to the extent it has knowledge of such conveyance, shall enforce any due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent permitted under applicable law and governmental regulations, but only to the extent that such enforcement will not adversely affect or jeopardize coverage under any Primary Mortgage Insurance Policy. Notwithstanding the foregoing, the Servicer is not required to exercise such rights with respect to a Mortgage Loan if the Person to whom the related Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the terms and conditions contained in the Mortgage Note and

Mortgage related thereto and the consent of the Mortgagee under such Mortgage Note or Mortgage is not otherwise so required under such Mortgage Note or Mortgage as a condition to such transfer. In the event that the Servicer is prohibited by law from enforcing any such due-on-sale clause, or if coverage under any Primary Mortgage Insurance Policy would be adversely affected, or if nonenforcement is otherwise permitted hereunder, the Servicer is authorized, subject to Section 3.06(b), to take or enter into an assumption and modification agreement from or with the person to whom such property has been or is about to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, unless prohibited by applicable state law, the Mortgagor remains liable thereon, provided that the Mortgage Loan shall continue to be covered (if so covered before the Servicer enters such agreement) by the applicable Primary Mortgage Insurance Policy. The Servicer, subject to Section 3.06(b), is also authorized with the prior approval of the insurers under any Primary Mortgage Insurance Policy to enter into a substitution of liability agreement with such Person, pursuant to which the original Mortgagor is released from liability and such Person is substituted as Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the foregoing, the Servicer shall not be deemed to be in default under this Section by reason of any transfer or assumption which the Servicer reasonably believes it is restricted by law from preventing, for any reason whatsoever.

(b) Subject to the Servicer’s duty to enforce any due-on-sale clause to the extent set forth in Section 3.06(a), in any case in which a Mortgaged Property is to be conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption or modification agreement or supplement to the Mortgage Note or Mortgage which requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the Mortgage Loan, the Servicer is authorized, subject to the requirements of the sentence next following, to execute and deliver, on behalf of the Trustee, the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person; provided, however, that in connection with any such assumption, no material term of the Mortgage Note may be changed. Upon receipt of appropriate instructions from the Servicer in accordance with the foregoing, the Trustee shall execute any necessary instruments for such assumption or substitution of liability delivered to it by the Servicer and as directed in writing by the Servicer. Upon the closing of the transactions contemplated by such documents, the Servicer shall cause the originals or true and correct copies of the assumption agreement, the release (if any), or the modification or supplement to the Mortgage Note or Mortgage to be delivered to the Trustee or the Custodian and deposited with the Mortgage File for such Mortgage Loan. Any fee collected by the Servicer or such related subservicer for entering into an assumption or substitution of liability agreement will be retained by the Servicer or such subservicer as additional servicing compensation.

Section 3.07 Release of Mortgage Files. (a) Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by the 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, (or if the Servicer does not, the Trustee 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 Custodial Account maintained by the Servicer pursuant to Section 4.01 have been or will be so deposited) and shall request that the Custodian, on behalf of the Trustee, deliver to the 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 Servicer and the Trustee and Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, the 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 Custodial Account.

In the event the Servicer satisfies or releases a Mortgage without having obtained payment in full of the indebtedness secured by the Mortgage or should it otherwise prejudice any right the Certificateholders or the Depositor may have under the Mortgage Loan Documents, the Servicer, upon written demand by the Depositor or the Trustee, shall remit within one Business Day the then outstanding principal balance of the related Mortgage Loan by deposit thereof in the Custodial Account.

(b) From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by the Servicer (in a 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 the 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. Such trust receipt shall obligate the Servicer to return the Mortgage File to the Custodian on behalf of the Trustee, when the need therefor by the 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 or to the Servicer.

Section 3.08 Documents, Records and Funds in Possession of Servicer To Be Held for Trustee.

(a) The Servicer shall transmit to the Trustee or Custodian such documents and instruments coming into the possession of the Servicer from time to time as are required by the terms hereof, to be delivered to the Trustee or Custodian. Any funds received by the Servicer in respect of any Mortgage Loan or which otherwise are collected by the 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 Servicer’s right to retain or withdraw from the Custodial Account the Servicing Fee and other amounts as provided in this Agreement. The

Servicer shall 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 Servicer designated by it. In fulfilling such a request the 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 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 Servicer for and on behalf of the Trustee and the Certificateholders and shall be and remain the sole and exclusive property of the Trust; provided, however, that the Servicer shall be entitled to setoff against, and deduct from, any such funds any amounts that are properly due and payable to the Servicer under this Agreement.

Section 3.09

Standard Hazard Insurance and Flood Insurance Policies.

(a) The Servicer shall cause to be maintained for each Mortgage Loan fire and hazard insurance with extended coverage as is customary in the area where the Mortgaged Property is located in an amount which is equal to the lesser of (i) the maximum insurable value of the improvements securing such Mortgage Loan or (ii) the greater of (a) the outstanding principal balance of the Mortgage Loan, and (b) the percentage such that the proceeds thereof shall be sufficient to prevent the Mortgagor and/or the Mortgagee from becoming a co-insurer. If the Mortgaged Property is in an area identified in the Federal Register by the Federal Emergency Management Agency as being a special flood hazard area that has federally-mandated flood insurance requirements, the Servicer will cause to be maintained a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration with a generally acceptable insurance carrier, in an amount representing coverage not less than the least of (i) the outstanding principal balance of the Mortgage Loan, (ii) the maximum insurable value of the improvements securing such Mortgage Loan or (iii) the maximum amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended. The Servicer shall also maintain on the REO Property, fire and hazard insurance with extended coverage in an amount which is at least equal to the maximum insurable value of the improvements which are a part of such property, liability insurance and, to the extent required and available under the Flood Disaster Protection Act of 1973, as amended, flood insurance in an amount as provided above. It is understood and agreed that no other additional insurance need be required by the Servicer or the Mortgagor or maintained on property acquired in respect of the Mortgage Loans, other than pursuant to the Fannie Mae Guide or such applicable state or federal laws and regulations as shall at any time be in force and as shall require such additional insurance. All such policies shall be endorsed with standard mortgagee clauses with loss payable to the Servicer and its successors and/or assigns and shall provide for at least thirty days prior written notice of any cancellation, reduction in the amount or material change in coverage to the Servicer. The Servicer shall not interfere with the Mortgagor's freedom of choice in selecting a

insurance carrier or agent, provided, however, that the Servicer shall not accept any such insurance policies from insurance companies unless such companies currently reflect a General Policy Rating in Best's Key Rating Guide currently acceptable to Fannie Mae and are licensed to do business in the state wherein the property subject to the policy is located.

(b) If the Servicer shall obtain and maintain a blanket hazard insurance policy with extended coverage insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations as set forth in the first sentence of Section 3.09(a), it being understood and agreed that such policy may contain a deductible clause, in which case the Servicer shall, in the event that there shall not have been maintained on the related Mortgaged Property a policy complying with the first sentence of Section 3.09(a) and there shall have been a loss which would have been covered by such policy, deposit in the Custodial Account the amount not otherwise payable under the blanket policy because of such deductible clause.

(c) Pursuant to Section 4.01, any amounts collected by the Servicer, under any insurance policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage) shall be deposited into the Custodial Account, subject to withdrawal pursuant to Section 4.02. Any cost incurred by the 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 Servicer pursuant to Section 4.02.

Section 3.10 Presentment of Claims and Collection of Proceeds. The Servicer shall 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 Servicer in respect of such policies, bonds or contracts shall be promptly deposited in the Custodial 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 Servicer shall not take, or permit any subservicer 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 Servicer or such subservicer, would have been covered thereunder. The Servicer shall cause to be kept 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. The Servicer shall not, and shall not permit any subservicer 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. Any such primary mortgage insurance policies shall be issued by a Qualified Insurer.

(b) The Servicer agrees to present, or to cause each subservicer 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, any amounts collected by the Servicer under any Primary Mortgage Insurance Policies shall be deposited in the Custodial Account, subject to withdrawal pursuant to Section 4.02.

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 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 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 Servicer from time to time.

Section 3.13 Realization Upon Defaulted Mortgage Loans. The Servicer shall use its reasonable efforts, consistent with the procedures that the Servicer would use in servicing loans for its own account and the requirements of the Fannie Mae Guide, to foreclose upon 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 pursuant to Section 4.01. The Servicer shall use its reasonable efforts to realize upon defaulted Mortgage Loans in such manner as will maximize the receipt of principal and interest by the Depositor, taking into account, among other things, the timing of foreclosure proceedings. The foregoing is subject to the provisions that, in any case in which Mortgaged Property shall have suffered damage, the Servicer shall not be required to expend its own funds toward the restoration of such property unless it shall determine in its discretion (i) that such restoration will increase the proceeds of liquidation of the related Mortgage Loan to the Depositor after reimbursement to itself for such expenses, and (ii) that such expenses will be recoverable by the Servicer through Insurance Proceeds or Liquidation Proceeds from the related Mortgaged Property, as contemplated in Section 4.02. The Servicer shall be responsible for all costs and expenses incurred by it in any such proceedings or functions as advances; provided, however, that it shall be entitled to reimbursement therefor as provided in Section 4.02. Notwithstanding anything to the contrary contained herein, in connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in the event the Servicer has reasonable cause to believe that a Mortgaged Property is

contaminated by hazardous or toxic substances or wastes, or if the Trustee otherwise requests an environmental inspection or review of such Mortgaged Property, such an inspection or review is to be conducted by a qualified inspector. Upon completion of the inspection, the Servicer shall promptly provide the Depositor and the Trustee with a written report of the environmental inspection.

Section 3.14 Compensation for the Servicer. The Servicer will be entitled to the Servicing Fee and all income and gain realized from any investment of funds in the Custodial Account, pursuant to Article IV, 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 Charges) shall be retained by the Servicer and shall not be deposited in the Custodial Account. The Servicer will be entitled to retain, as additional compensation, any interest incurred 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 “Servicing Compensation”) and any Excess Liquidation Proceeds. The 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.

(a) In the event the Trust Fund acquires ownership of any REO Property in respect of any related Mortgage Loan, the deed or certificate of sale shall be issued to the Trustee, or to its nominee, on behalf of the related Certificateholders. The Servicer shall ensure that the title to such REO Property references this Agreement and the Trustee’s capacity hereunder (and not in its individual capacity). The Servicer, however, shall not be required to expend its own funds or incur other reimbursable charges in connection with any foreclosure, or attempted foreclosure which is not completed, or towards the restoration of any property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the Mortgage Loan to Holders of Certificates of one or more Classes after reimbursement to itself for such expenses or charges and (ii) that such expenses or charges will be recoverable to it through Liquidation Proceeds, Insurance Proceeds, or REO Proceeds (respecting which it shall have priority for purposes of withdrawals from the Custodial Account pursuant to Section 4.02, whether or not such expenses and charges are actually recoverable from related Liquidation Proceeds, Insurance Proceeds or REO Proceeds). In the event of such a determination by the Servicer pursuant to this Section 3.15(a), the Servicer shall be entitled to reimbursement of such amounts pursuant to Section 4.02. If the Servicer has knowledge that a Mortgaged Property which the Servicer is contemplating acquiring in foreclosure or by deed in lieu of foreclosure is located within a one (1) mile radius of any site listed in the Expenditure Plan for the Hazardous Substance Clean Up Bond Act of 1984 or other site with environmental or hazardous waste risks known to the Servicer, the Servicer will, prior to acquiring the Mortgaged Property, consider such risks and only take action in accordance with its established environmental review procedures.

The Servicer shall, either itself or through an agent selected by the Servicer, manage, conserve, protect and operate each REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account, and in the same manner that

similar property in the same locality as the REO Property is managed, including 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. Each disposition of REO Property shall be carried out by the Servicer at such price and upon such terms and conditions as the Servicer deems to be in the best interest of the Certificateholders. The Servicer shall deposit all funds collected and received in connection with the operation of any REO Property in the Custodial Account pursuant to Section 4.01.

Upon the occurrence of a Cash Liquidation or REO Disposition, following the deposit in the Custodial Account of all Insurance Proceeds, Liquidation Proceeds and other payments and recoveries referred to in the definition of “Cash Liquidation” or “REO Disposition,” as applicable, upon receipt by the Trustee of written notification of such deposit signed by a Servicing Officer, the Trustee or any Custodian, as the case may be, shall release to the Servicer the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment prepared by the Servicer, in each case without recourse, as shall be necessary to vest in the Servicer or its designee, as the case may be, the related Mortgage Loan, and thereafter such Mortgage Loan shall not be part of the Trust Fund.

(b) If title to any Mortgaged Property is acquired by the Trust Fund as an REO Property by foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale shall be issued to the Trustee or to its nominee on behalf of Certificateholders. Notwithstanding any such acquisition of title and cancellation of the related Mortgage Loan, such REO Property shall (except as otherwise expressly provided herein) be considered to be an Outstanding Mortgage Loan held in the Trust Fund until such time as the REO Property shall be sold. Consistent with the foregoing for purposes of all calculations hereunder so long as such REO Property shall be considered to be an Outstanding Mortgage Loan it shall be assumed that, notwithstanding that the indebtedness evidenced by the related Mortgage Note shall have been discharged, such Mortgage Note and the related amortization schedule in effect at the time of any such acquisition of title (after giving effect to any previous Curtailments and before any adjustment thereto by reason of any bankruptcy or similar proceeding or any moratorium or similar waiver or grace period) remain in effect. To the extent the net income received during any calendar month is in excess of the amount attributable to amortizing principal and accrued interest at the related Mortgage Rate on the related Mortgage Loan for such calendar month, such excess shall be considered to be a Curtailment of the related Mortgage Loan.

(c) If the Trust Fund acquires any REO Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the Servicer on behalf of the Trust Fund shall dispose of such REO Property within three full years after the taxable year of its acquisition by the Trust Fund for purposes of Section 860G(a)(8) of the Code (or such shorter period as may be necessary under applicable state (including any state in which such property is located) law to maintain the status of any portion of the applicable REMIC as a REMIC under applicable state law and avoid taxes resulting from such property failing to be foreclosure property under applicable state law) or, at the expense of the Trust Fund, request, more than 60 days before the day on which such grace period would otherwise expire, an extension of such grace period unless the Servicer obtains for the Trustee an Opinion of Counsel, addressed to the

Trustee and the Servicer, to the effect that the holding by the Trust Fund of such REO Property subsequent to such period will not result in the imposition of taxes on “prohibited transactions” as defined in Section 860F of the Code or cause the applicable REMIC to fail to qualify as a REMIC (for federal (or any applicable State or local) income tax purposes) at any time that any Certificates are outstanding, in which case the Trust Fund may continue to hold such REO Property (subject to any conditions contained in such Opinion of Counsel). The Servicer shall be entitled to be reimbursed from the Custodial Account for any costs incurred in obtaining such Opinion of Counsel, as provided in Section 4.02. Notwithstanding any other provision of this Agreement, no REO Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or (ii) subject the Trust Fund to the imposition of any federal income taxes on the income earned from such REO Property, including any taxes imposed by reason of Section 860G(c) of the Code, unless the Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

Section 3.16

Annual Officer’s Certificate as to Compliance.

(a) The Servicer shall deliver to the Trustee and the Rating Agencies on or before March 1 of each year, commencing on March 1, 2006, an Officer’s Certificate, certifying that with respect to the period ending December 31 of the prior year: (i) such Servicing Officer has reviewed the activities of the Servicer during the preceding calendar year or portion thereof and its performance under this Agreement, (ii) to the best of such Servicing Officer’s knowledge, based on such review, such Servicer has performed and fulfilled its duties, responsibilities and obligations under this Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof, (iii) nothing has come to the attention of such Servicing Officer to lead such Servicing Officer to believe that the Servicer has failed to perform any of its duties, responsibilities and obligations under this Agreement in all material respects throughout such year, or, if there has been a material default in the performance or fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof.

(b) Copies of such statements shall be provided to any Certificateholder upon request, by the Servicer or by the Trustee at the Servicer’s expense if the Servicer failed to provide such copies (unless (i) the Servicer shall have failed to provide the Trustee with such statement or (ii) the Trustee shall be unaware of the Servicer’s failure to provide such statement).

Section 3.17 Annual Independent Accountant’s Servicing Report. The Servicer at its expense shall cause a nationally recognized firm of independent certified public accountants to furnish a statement to the Trustee, the Rating Agencies and the Depositor on or before March 1 of each year, commencing on March 1, 2006 to the effect that, with respect to the most recently ended calendar year, such firm has examined certain records and documents relating to the Servicer’s performance of its servicing obligations under this Agreement and pooling and servicing and trust agreements in material respects similar to this Agreement and to each other and that, on the basis of such examination conducted substantially in compliance with the audit

program for mortgages serviced for Freddie Mac or the Uniform Single Attestation Program for Mortgage Bankers, such firm is of the opinion that the Servicer’s activities have been conducted in compliance with this Agreement, or that such examination has disclosed no material items of noncompliance except for (i) such exceptions as such firm believes to be immaterial, (ii) such other exceptions as are set forth in such statement and (iii) such exceptions that the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it to report. Copies of such statements shall be provided to any Certificateholder upon request by the Servicer, or by the Trustee at the expense of the Servicer if the Servicer shall fail to provide such copies. If such report discloses exceptions that are material, the Servicer shall advise the Trustee whether such exceptions have been or are susceptible of cure, and will take prompt action to do so.

Section 3.18 Reports Filed with Securities and Exchange Commission. Within 15 days after each Distribution Date, the Trustee shall, in accordance with industry standards, file with the Commission via the Electronic Data Gathering and Retrieval System (“EDGAR”), a Form 8-K (or other comparable form containing the same or comparable information or other information mutually agreed upon) with a copy of the statement to the Certificateholders for such Distribution Date as an exhibit thereto. Prior to January 30 of each year, the Trustee shall, in accordance with industry standards and only if instructed by the Depositor, file a Form 15 Suspension Notice with respect to the Trust Fund, if applicable. Prior to (i) March 15, 2006 and (ii) unless and until a Form 15 Suspension Notice shall have been filed, prior to March 15 of each year thereafter, the Servicer shall provide the Trustee with a Servicer Certification, together with a copy of the annual independent accountant’s servicing report and annual statement of compliance required to be delivered by the Servicer pursuant to Sections 3.16 and 3.17. Prior to (i) March 31, 2006, or such earlier filing date as may be required by the Commission, and (ii) unless and until a Form 15 Suspension Notice shall have been filed, March 31 of each year thereafter, or such earlier filing date as may be required by the Commission, the Trustee shall prepare and file a Form 10-K, in substance conforming to industry standards, with respect to the Trust. Such Form 10-K shall be executed on behalf of the Depositor by the Servicer and shall include the Servicer Certification and other documentation provided by the Servicer pursuant to the second preceding sentence. The Depositor hereby grants to the Trustee a limited power of attorney to execute each Form 8-K (or comparable form) and to file each Form 8-K and Form 10-K on behalf of the Depositor. Such power of attorney shall continue until either the earlier of (i) receipt by the Trustee from the Depositor of written termination of such power of attorney and (ii) the termination of the Trust Fund. The Depositor agrees to promptly furnish to the Trustee, from time to time upon request, such further information, reports and financial statements within its control related to this Agreement and the Mortgage Loans as the Trustee reasonably deems appropriate to prepare and file all necessary reports with the Commission. The Trustee shall have no responsibility to file any items other than those specified in this Section 3.18; provided, however, the Trustee will cooperate with the Depositor in connection with any additional filings with respect to the Trust Fund as the Depositor deems necessary under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Fees and expenses incurred by the Trustee in connection with this Section 3.18 shall not be reimbursable from the Trust Fund.

Section 3.19 UCC. The Depositor shall inform the Trustee in writing of any Uniform Commercial Code financing statements that were filed on the Closing Date and each Subsequent Transfer Date in connection with the Trust with stamped recorded copies of such financing

statements to be delivered to the Trustee promptly upon receipt by the Depositor. The Trustee agrees to monitor and notify the Depositor if any continuation statements for such Uniform Commercial Code financing statements need to be filed. If directed by the Depositor in writing, the Trustee will file any such continuation statements solely at the expense of the Depositor. The Depositor shall file any financing statements or amendments thereto required by any change in the Uniform Commercial Code.

Section 3.20

Optional Purchase of Defaulted Mortgage Loans.

(a) With respect to any Mortgage Loan which as of the first day of a Fiscal Quarter is delinquent in payment by 90 days or more or is an REO Property, the Company shall have the right to purchase such Mortgage Loan from the Trust at a price equal to the Repurchase Price; provided however (i) that such Mortgage Loan is still 90 days or more delinquent or is an REO Property as of the date of such purchase and (ii) this purchase option, if not theretofore exercised, shall terminate on the date prior to the last day of the related Fiscal Quarter. This purchase option, if not exercised, shall not be thereafter reinstated unless the delinquency is cured and the Mortgage Loan thereafter again becomes 90 days or more delinquent or becomes an REO Property, in which case the option shall again become exercisable as of the first day of the related Fiscal Quarter.

(b) If at any time the Company deposits, or remits to the Servicer (to the extent it is not the Servicer) for deposit, in the Custodial Account the amount of the Repurchase Price for a Mortgage Loan and the Company provides to the Trustee a certification signed by a Servicing Officer stating that the amount of such payment has been deposited in the Custodial Account, then the Trustee shall execute the assignment of such Mortgage Loan to the Company at the request of the Company without recourse, representation or warranty and the Company shall succeed to all of the Trustee’s right, title and interest in and to such Mortgage Loan, and all security and documents relative thereto. Such assignment shall be an assignment outright and not for security. The Company will thereupon own such Mortgage, and all such security and documents, free of any further obligation to the Trustee or the Certificateholders with respect thereto.

ARTICLE IV

Accounts

Section 4.01 Custodial Account. (a) The Servicer shall segregate and hold all funds collected and received pursuant to each Mortgage Loan separate and apart from any of its own funds and general assets and shall establish and maintain one or more Custodial Accounts held in trust for the Certificateholders. Each Custodial Account shall be an Eligible Account. The Custodial Account shall be maintained as a segregated account, separate and apart from trust funds created for mortgage pass-through certificates of other series, and the other accounts of the Servicer.

Within two Business Days of receipt, except as otherwise specifically provided herein, the Servicer shall deposit or cause to be deposited the following payments and collections remitted by subservicers or received by it in respect of the Mortgage Loans subsequent to the Cut-off Date (other than in respect of principal and interest due on such Mortgage Loans on or before the Cut-off Date) and the following amounts required to be deposited hereunder:

(i) Scheduled Payments on the Mortgage Loans received or any related portion thereof advanced by the Servicer which were due during or before the related Due Period, net of the amount thereof comprising the Servicing Fee;

(ii) Full Principal Prepayments and any Liquidation Proceeds received by the 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 the Servicing Fee;

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

(iv)	Any Monthly Advance and any Compensating Interest Payments;

(v) Any Insurance Proceeds or Net Liquidation Proceeds received by or on behalf of the Servicer;

(vii) Any amounts required to be deposited with respect to losses on investments of deposits in an Account;

(viii) Any amounts received by the Servicer in connection with any Prepayment Charge on the Prepayment Charge Loans; and

(b) All amounts deposited to the Custodial Account shall be held by the Servicer in the name of the Trustee in trust for the benefit of the Certificateholders in accordance with the terms and provisions of this Agreement. The requirements for crediting the Custodial Account or the Distribution Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of (i) late payment charges or assumption, tax service, statement account or payoff, substitution, satisfaction, release and other like fees and charges and (ii) the items enumerated in Sections 4.04(a)(i) through (iv) and (vi) through (xi) with respect to the Trustee and the Servicer, need not be credited by the Servicer to the Distribution Account or the Custodial Account, as applicable. Amounts received by the Servicer in connection with Prepayment Charges on the Prepayment Charge Loans shall be remitted by the Servicer to the Trustee and deposited by the Trustee into the Class XP Reserve Account upon receipt thereof. In the event that the Servicer shall deposit or cause to be deposited to the Distribution Account any amount not required to be credited thereto, the Trustee, upon receipt of a written request therefor signed by a Servicing Officer of the Servicer, shall promptly transfer such amount to the Servicer, any provision herein to the contrary notwithstanding.

(c) The amount at any time credited to the Custodial Account may be invested, in the name of the Trustee, or its nominee, for the benefit of the Certificateholders, in Permitted Investments as directed by the Servicer. All Permitted Investments shall mature or be subject to redemption or withdrawal on or before, and shall be held until, the next succeeding Distribution Account Deposit Date. Any and all investment earnings on amounts on deposit in the Custodial Account from time to time shall be for the account of the Servicer. The Servicer from time to time shall be permitted to withdraw or receive distribution of any and all investment earnings from the Custodial Account. 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 Servicer. The Servicer shall deposit the amount of any such loss in the Custodial 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.

Section 4.02 Permitted Withdrawals and Transfers from the Custodial Account. (a) The Servicer will, from time to time on demand of the Trustee, make or cause to be made such withdrawals or transfers from the Custodial Account as the Servicer has designated for such transfer or withdrawal pursuant to this Agreement. The Servicer may clear and terminate the Custodial Account pursuant to Section 10.01 and remove amounts from time to time deposited in error.

(b) On an ongoing basis, the Servicer shall withdraw from the Custodial Account (i) any expenses recoverable by the Trustee, the Servicer or the Custodian pursuant to Sections 3.03, 7.04 and 9.05 and (ii) any amounts payable to the Servicer as set forth in Section 3.14.

(c) In addition, on or before each Distribution Account Deposit Date, the Servicer shall deposit in the Distribution Account (or remit to the Trustee for deposit therein) any Monthly Advances required to be made by the Servicer with respect to the Mortgage Loans.

(d) No later than 3:00 p.m. New York time on each Distribution Account Deposit Date, the Servicer will transfer all Available Funds on deposit in the Custodial Account with respect to the related Distribution Date to the Trustee for deposit in the Distribution Account.

(e) With respect to any remittance received by the Trustee after the Distribution Account Deposit Date on which such payment was due, the Servicer shall pay to the Trustee interest on any such late payment at an annual rate equal to the Prime Rate, adjusted as of the date of each change of the Prime Rate, plus two percentage points, but in no event greater than the maximum amount permitted by applicable law. Such interest shall be remitted to the Trustee by the Servicer on the date such late payment is made and shall cover the period commencing with such Distribution Account Deposit Date and ending with the Business Day on which such payment is made, both inclusive. The payment by the Servicer of any such interest shall not be deemed an extension of time for payment or a waiver of any Event of Default by the Servicer.

Section 4.03 Distribution Account. (a) The Trustee 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. The Trustee shall deposit into the Distribution Account all amounts in respect to Available Funds received by it from the Servicer.

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

(c) The Distribution Account shall constitute a trust account of the Trust Fund segregated on the books of the Trustee and held by the Trustee in trust in its Corporate Trust Office, and the Distribution Account and the funds deposited therein shall not be subject to, and shall be protected from, all claims, liens, and encumbrances of any creditors or depositors of the Trustee (whether made directly, or indirectly through a liquidator or receiver of the Trustee). The Distribution Account shall be an Eligible Account. The amount at any time credited to the Distribution Account may be invested in the name of the Trustee in Permitted Investments selected by the Trustee. 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 Trustee or, if such obligor is any other Person, the Business Day preceding such Distribution Date. All investment earnings on amounts on deposit in the Distribution Account or benefit from funds uninvested therein from time to time shall be for the account of the Trustee. The Trustee shall be permitted to withdraw or receive distribution of any and all investment earnings from the Distribution Account on each Distribution Date. If there is any loss on a Permitted Investment, the Trustee shall deposit the amount of such loss for deposit in the Distribution Account. With respect to the Distribution Account and the funds deposited therein, the Trustee 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.

Section 4.04 Permitted Withdrawals and Transfers from the Distribution Account. (a) The Trustee will, from time to time on demand of the Servicer, make or cause to be made such withdrawals or transfers from the Distribution Account as the Servicer has designated for such transfer or withdrawal pursuant to this Agreement or as the Trustee deems necessary for the following purposes (limited in the case of amounts due the Servicer to those not withdrawn from the Custodial Account in accordance with the terms of this Agreement):

(i) to reimburse itself or the Servicer for any Monthly Advance of its own funds, the right of the Trustee or the 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;

(ii) to reimburse the Servicer from Insurance Proceeds or Liquidation Proceeds relating to a particular Mortgage Loan for amounts expended by the Servicer in good faith in connection with the restoration of the related Mortgaged Property which was damaged by an Uninsured Cause or in connection with the liquidation of such Mortgage Loan;

(iii) to reimburse the Servicer from Insurance Proceeds relating to a particular Mortgage Loan for insured expenses incurred with respect to such Mortgage Loan and to reimburse the Servicer from Liquidation Proceeds from a particular Mortgage Loan for Liquidation Expenses incurred with respect to such Mortgage Loan; provided that the 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 (x) of this Section 4.04(a) to the Servicer; and (ii) such Liquidation Expenses were not included in the computation of such Excess Liquidation Proceeds;

(iv) to pay the Servicer, from Liquidation Proceeds or Insurance Proceeds received in connection with the liquidation of any Mortgage Loan, the amount which the Servicer would have been entitled to receive under clause (ix) of this Section 4.04(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;

(v) to pay the Servicer from the Repurchase Price for any Mortgage Loan, the amount which the Servicer would have been entitled to receive under clause (ix) of this Section 4.04(a) as servicing compensation;

(vi) to reimburse the 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;

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

(viii)

to pay the Servicer as set forth in Section 3.14;

(ix) to reimburse the Servicer for expenses, costs and liabilities incurred by and reimbursable to it pursuant to Sections 3.03, 7.04(c) and (d);

(x) to pay to the Servicer, as additional servicing compensation, any Excess Liquidation Proceeds;

(xi) to reimburse the Trustee or the Custodian for expenses, costs and liabilities incurred by or reimbursable to it pursuant to this Agreement;

(xii)	to remove amounts deposited in error; and
(xiii)	to clear and terminate the Distribution Account pursuant to Section 10.01.

(b) The Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis and shall provide a copy to the Trustee, for the purpose of accounting for any reimbursement from the Distribution Account pursuant to clauses (i) through (vi) and (vii) or with respect to any such amounts which would have been covered by such clauses had the amounts not been retained by the Servicer without being deposited in the Distribution Account under Section 4.01(b). Reimbursements made pursuant to clauses (vii), (ix) and (xi) will be allocated between the Loan Groups pro rata based on the aggregate Scheduled Principal Balances of the Mortgage Loans in each Loan Group.

(c) On each Distribution Date, the Trustee shall distribute the Available Funds to the extent on deposit in the Distribution Account for each Loan Group to the Holders of the related Certificates in accordance with Section 6.01.

Section 4.05

Class A Reserve Fund.

(a) No later than the Closing Date, the Paying Agent shall establish and maintain a segregated trust account or sub-account of a trust account, which shall be titled “Class A Reserve Fund, Wells Fargo Bank, National Association, as trustee for the benefit of holders of Structured Asset Mortgage Investments II Inc., GreenPoint Mortgage Funding Trust 2005-AR4, Mortgage Pass-Through Certificates, Series 2005-AR4” (the “Class A Reserve Fund”). The Class A Reserve Fund shall be an Eligible Account or a sub-account of an Eligible Account. On the Closing Date, the Depositor shall pay to the Paying Agent an amount equal to approximately $2,478,331 which shall be deposited by the Paying Agent into the Class A Reserve Fund. Pursuant to Section 6.01, on the initial Distribution Date, amounts on deposit in the Class A Reserve Fund will be withdrawn from the Class A Reserve Fund and deposited into the Distribution Account for payment to the Class I-A, Class II-A and Class IV-A Certificates to the extent that Accrued Certificate Interest on such Classes of Certificates is reduced by application of the related Net Rate Cap on such initial Distribution Date. In addition, on each Distribution Date through and including the Distribution Date occurring in November 2005, amounts on deposit in the Class A Reserve Fund will be withdrawn from the Class A Reserve Fund and

deposited into the Distribution Account for payment to the Class IV-A-2b Certificates to the extent that Accrued Certificate Interest on such Class of Certificates is reduced by application of the related Net Rate Cap on such Distribution Dates. The Class A Reserve Fund will then be entitled to be replenished on each future Distribution Date from amounts otherwise payable as interest on (i) the Class X-1 Certificates, in the case of withdrawals from the Class A Reserve Fund used to pay interest on the Class I-A Certificates on the initial Distribution Date, (ii) the Class X-2 Certificates, in the case of withdrawals from the Class A Reserve Fund used to pay interest on the Class II-A Certificates on the initial Distribution Date, or (iii) the Class X-4 Certificates, in the case of withdrawals from the Class A Reserve Fund used to pay interest on the Class IV-A Certificates on the initial Distribution Date, until the Class A Reserve Fund has been replenished to the amount deposited in such account as of the Closing Date. Once the Class A Reserve Fund has been replenished in full, all amounts in the Class A Reserve Fund will be distributed to the Depositor or its designee on the immediately following Distribution Date; and following such withdrawal the Class A Reserve Fund will be closed.

(b) The Paying Agent will invest funds deposited in the Class A Reserve Fund as directed by the Depositor or its designee in writing in Permitted Investments with a maturity date (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Paying Agent or an Affiliate of the Paying Agent is the obligor for the Permitted Investment, or (ii) no later than the date on which such funds are required to be withdrawn from such account or sub account of a trust account pursuant to this Agreement, if the Paying Agent or an affiliate of the Paying Agent is the obligor for the Permitted Investment (or, if no written direction is received by the Paying Agent from the Depositor, then funds in such account shall remain uninvested). For federal income tax purposes, the Depositor shall be the owner of the Class A Reserve Fund and shall report all items of income, deduction, gain or loss arising therefrom. At no time will the Class A Reserve Fund be an asset of any REMIC created hereunder. All income and gain realized from investment of funds deposited in the Class A Reserve Fund, which investment shall be made solely upon the written direction of the Depositor, shall be for the sole and exclusive benefit of the Depositor and shall be remitted by the Paying Agent to the Depositor within one Business Day from the closing of the Class A Reserve Fund. The Depositor shall deposit in the Class A Reserve Fund the amount of any net loss incurred in respect of any such Permitted Investment immediately upon realization of such loss.

The Pre-Funding Account shall be an Eligible Account or a sub-account of an Eligible Account. The Paying Agent shall, promptly upon receipt, deposit in the Pre-Funding Account and retain therein the Pre-Funded Amount remitted on the Closing Date to the Paying Agent by the Depositor. Funds deposited in the Pre-Funding Account shall be held in trust by the Paying Agent for the Holders of the related Certificates for the uses and purposes set forth herein.

(b) The Paying Agent will invest funds deposited in the Pre-Funding Account as directed by the Depositor or its designee in writing in Permitted Investments with a maturity date (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Paying Agent or an Affiliate of the Paying Agent is the obligor for the Permitted Investment, or (ii) no later than the date on which such funds are required to be withdrawn from such account or sub account of a trust account pursuant to this Agreement, if the Paying Agent or an affiliate

of the Paying Agent is the obligor for the Permitted Investment (or, if no written direction is received by the Paying Agent from the Depositor, then funds in such account shall remain uninvested). For federal income tax purposes, the Depositor or its designee shall be the owner of the Pre-Funding Account and shall report all items of income, deduction. gain or loss arising therefrom. All income and gain realized from investment of funds deposited in the Pre-Funding Account shall be transferred to the Interest Coverage Account at the following times: (i) on the Business Day immediately preceding each Distribution Date, if a Person other than the Paying Agent or an Affiliate of the Paying Agent is the obligor for the Permitted Investment, or on each Distribution Date, if the Paying Agent or an Affiliate of the Paying Agent is the obligor for the Permitted Investment, (ii) on the Business Day immediately preceding each Subsequent Transfer Date, if a Person other than the Paying Agent or an Affiliate of the Paying Agent is the obligor for the Permitted Investment, or on each Subsequent Transfer Date, if the Paying Agent or an Affiliate of the Paying Agent is the obligor for the Permitted Investment or (iii) within one Business Day of the Paying Agent's receipt thereof. Such transferred funds shall not constitute income and gain for purposes of Section 4.08(b) hereof. The Depositor or its designee shall deposit in the Pre-Funding Account the amount of any net loss incurred in respect of any such Permitted Investment immediately upon realization of such loss without any right of reimbursement therefor. At no time will the Pre-Funding Account be an asset of any REMIC created hereunder.

(i) On any Subsequent Transfer Date, the Paying Agent shall withdraw from the Pre-Funding Account an amount equal to 100% of the Scheduled Principal Balances of the Subsequent Mortgage Loans transferred to the Trust Fund and assigned to the Trustee for deposit in Loan Group IV on such Subsequent Transfer Date and deposit such amount into the Pre-Funding Reserve Account;

(ii) If the amount on deposit in the Pre-Funding Account (exclusive of investment income) has not been reduced to zero by the close of business on the date of termination of the Pre-Funding Period, then at the close of business on such date, the Paying Agent shall deposit into the Pre-Funding Reserve Account any amounts remaining in the Pre-Funding Account (exclusive of investment income) for distribution in accordance with Section 4.07(e)(iii);

(iii) To withdraw any amount not required to be deposited in the Pre-Funding Account or deposited therein in error; and

(iv) Upon the earliest of (i) the reduction of the Principal Balances of the Certificates to zero or (ii) the termination of this Agreement in accordance with Section 10.01, to withdraw (and deposit in the Pre-Funding Reserve Account) any amount remaining on deposit in the Pre-Funding Account for payment to the related Certificateholders then entitled to distributions in respect of principal until the Principal Balance of the Certificates has been reduced to zero, and any remaining amount to the Depositor; and following such withdrawal close the Account.

Withdrawals pursuant to clauses (i), (ii) and (iv) shall be treated as contributions of cash to REMIC II on the date of withdrawal.

(d) No later than the Closing Date, the Paying Agent shall establish and maintain a segregated trust account or a sub-account of a trust account, which shall be titled “Pre-Funding Reserve Account, Wells Fargo Bank, National Association, as Trustee for the benefit of holders of Structured Asset Mortgage Investments II Inc., GreenPoint Mortgage Funding Trust 2005-AR4, Mortgage Pass-Through Certificates, Series 2005-AR4” (the “Pre-Funding Reserve Account”). The Pre-Funding Reserve Account shall be an Eligible Account or a sub-account of an Eligible Account. The Paying Agent shall, at the close of business on the day of the termination of the Pre-Funding Period, deposit in the Pre-Funding Reserve Account and retain therein any funds remaining in the Pre-Funding Account at the close of business on such day. Funds deposited in the Pre-Funding Reserve Account shall be held in trust by the Paying Agent for the related Certificateholders for the uses and purposes set forth herein.

(ii) On each Distribution Date during the Pre-Funding Period and the Distribution Date immediately following termination of the Pre-Funding Period, the Paying Agent shall withdraw from the Pre-Funding Reserve Account the amount deposited therein on such date pursuant to Section 4.08(c) and deposit such funds in the Distribution Account for distribution as Available Funds for the related Loan Group pursuant to Section 6.01(a); and

(iii) On the Distribution Date immediately following termination of the Pre-Funding Period, the Paying Agent shall withdraw from the Pre-Funding Reserve Account the Remaining Pre-Funded Amount deposited therein pursuant to Section 4.07(c)(ii) and deposit such funds in the Distribution Account for distribution as Available Funds for the related Loan Group pursuant to Section 6.01(a), and shall close such Pre-Funding Reserve Account.

Section 4.08

(a) No later than the Closing Date, the Paying Agent shall establish and maintain a segregated trust account or a sub-account of a trust account, which shall be titled “Interest Coverage Account, Wells Fargo Bank, National Association, as trustee for the benefit of holders of Structured Asset Mortgage Investments II Inc., GreenPoint Mortgage Funding Trust 2005-

AR4, Mortgage Pass-Through Certificates, Series 2005-AR4” (the “Interest Coverage Account”). The Interest Coverage Account shall be an Eligible Account or a sub-account of an Eligible Account. The Paying Agent shall, promptly upon receipt, deposit in the Interest Coverage Account and retain therein the Interest Coverage Amount for each Loan Group remitted on the Closing Date to the Paying Agent by the Depositor and all income and gain realized from investment of funds deposited in the Pre-Funding Account pursuant to Section 4.07(b).

(b) The Paying Agent will invest funds deposited in the Interest Coverage Account as directed by the Depositor or its designee in writing in Permitted Investments with a maturity date (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Paying Agent or an Affiliate of the Paying Agent is the obligor for the Permitted Investment, or (ii) no later than the date on which such funds are required to be withdrawn from such account or sub account of a trust account pursuant to this Agreement, if the Paying Agent or an affiliate of the Paying Agent is the obligor for the Permitted Investment (or, if no written direction is received by the Paying Agent from the Depositor, then funds in such account shall remain uninvested). For federal income tax purposes, the Depositor shall be the owner of the Interest Coverage Account and shall report all items of income, deduction, gain or loss arising therefrom. At no time will the Interest Coverage Account be an asset of any REMIC created hereunder. All income and gain realized from investment of funds deposited in the Interest Coverage Account, which investment shall be made solely upon the written direction of the Depositor, shall be for the sole and exclusive benefit of the Depositor and shall be remitted by the Paying Agent to the Depositor within one Business Day from the closing of the Interest Coverage Account. If no written direction with respect to such investment shall be received by the Paying Agent from the Depositor, then funds in such Account shall remain uninvested. The Depositor shall deposit in the Interest Coverage Account the amount of any net loss incurred in respect of any such Permitted Investment immediately upon realization of such loss.

(c) On each Distribution Date during the Pre-Funding Period and on the day of termination of the Pre-Funding Period, the Paying Agent shall withdraw from the Interest Coverage Account and deposit in the Pre-Funding Reserve Account an amount of interest that accrues during the related Interest Accrual Period at the weighted average of the Pass-Through Rates on the Group IV Certificates, weighted on the basis of the Outstanding Current Principal Amount of the Group IV Certificates on the excess, if any, of the Pre-Funded Amount over the aggregate Scheduled Principal Balance of Subsequent Mortgage Loans that both (i) had a Due Date during the Due Period relating to such Distribution Date or the Distribution Date following the end of the Pre-Funding Period, as applicable, and (ii) had a Subsequent Cut-off Date prior to the first day of the month in which such Distribution Date occurs. Such withdrawal and deposit shall be treated as a contribution of cash by the Seller to REMIC II on the date thereof. Immediately following any such withdrawal and deposit, and immediately following the conveyance of any Subsequent Mortgage Loan to the Trust on any Subsequent Transfer Date, the Paying Agent shall, at the request of the Seller, withdraw from the Interest Coverage Account and remit to the Seller or its designee an amount equal to the excess, if any, of the amount remaining in such Interest Coverage Account over the amount that would be required to be withdrawn therefrom (assuming sufficient funds therein) pursuant to the second preceding

sentence on each subsequent Distribution Date, if any, that will occur during the Pre-Funding Period or on the day of termination of the Pre-Funding Period, if no Subsequent Mortgage Loans were acquired by the Trust Fund after the end of the Prepayment Period relating to the current Distribution Date or the Distribution Date following the end of the Pre-Funding Period, as applicable. On the day of termination of the Pre-Funding Period, the Paying Agent shall withdraw from the Interest Coverage Account and remit to the Seller or its designee the amount remaining in such Interest Coverage Account after payment of the amount required to be withdrawn therefrom pursuant to the second preceding sentence on the day of termination of the Pre-Funding Period.

(d) Upon the earliest of (i) the Distribution Date immediately following the end of the Pre-Funding Period, (ii) the reduction of the principal balances of the Certificates to zero or (iii) the termination of this Agreement in accordance with Section 10.01, any amount remaining on deposit in the Interest Coverage Account after distributions pursuant to paragraph (c) above shall be withdrawn by the Paying Agent and paid to the Seller or its designee; and following such withdrawal the Account will be closed.

Section 4.09 Class XP Reserve Account. (a) The Paying Agent shall establish and maintain with itself a separate, segregated trust account, which shall be an Eligible Account, titled “Reserve Account, Wells Fargo Bank, National Association, as Trustee for the benefit of holders of Structured Asset Mortgage Investments II Inc., GreenPoint Mortgage Funding Trust 2005-AR4, Mortgage Pass-Through Certificates, Series 2005-AR4, Class XP”. Funds on deposit in the Class XP Reserve Account shall be held in trust by the Trustee for the holder of the Class XP Certificates. The Class XP Reserve Account will not represent an interest in any REMIC.

(b) Any amount on deposit in the Class XP Reserve Account shall be held uninvested. On the Business Day prior to each Distribution Date, the Trustee shall withdraw the amount then on deposit in the Class XP Reserve Account and deposit such amount into the Distribution Account to be distributed to the Holders of the Class XP Certificates in accordance with Section 6.01(f). 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 August 2011, the Trustee shall withdraw the amount on deposit in the Class XP Reserve Account and deposit such amount into the Distribution Account and pay such amount to the Class XP Certificates in accordance with Section 6.01(f), and following such withdrawal the Class XP Reserve Account shall be closed.

ARTICLE V

Certificates

Section 5.01 Certificates. (a) The Depository, the Depositor and the Trustee 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 Trustee 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 Trustee 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 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 Trustee cause such Class to become Global Certificates, the Trustee 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 Trustee 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 Trustee in writing that it elects to terminate the book-entry system through the Depository, the Trustee 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 Trustee of the Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Trustee 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

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 Trustee 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 Trustee of instructions from the Depository directing the Trustee to effect such exchange (such instructions to contain information regarding the Class of Certificates and the Current 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 Trustee), (i) the Trustee shall instruct the Depository to reduce the related Depository Participant’s account by the aggregate Current Principal Balance of the definitive Certificate, (ii) the Trustee 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 Trustee shall execute a new Book-Entry Certificate reflecting the reduction in the aggregate Current Principal Balance of such Class of Certificates by the amount of the definitive Certificates.

Neither the Depositor nor the Trustee 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 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, pass-through rate (the “Uncertificated Pass-Through Rate”) and initial Uncertificated Principal Balance for each of the “regular interests” in REMIC I (the “REMIC I Regular Interests”). The “latest possible maturity date” (determined solely for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii)) for each REMIC I Regular Interest shall be the Maturity Date. None of the REMIC I Regular Interests will be certificated. The REMIC I Regular Interests and Component I of the Class R Certificates will have the following designations, initial balances and pass-through rates:

(ii) As provided herein, the REMIC Administrator will make an election to treat the segregated pool of assets consisting of the REMIC I Regular Interests as a real estate mortgage investment conduit (a “REMIC”) for federal income tax purposes, and such segregated pool of assets will be designated as “REMIC II.” Component II of the Class R Certificates will represent the sole Class of “residual interests” in REMIC II for purposes of the REMIC Provisions (as defined herein) under federal income tax law. The following table irrevocably sets forth the designation, remittance rate (the “Uncertificated REMIC II Pass-Through Rate”) and initial Uncertificated Principal Balance for each of the “regular interests” in REMIC II (the “REMIC II Regular Interests”) and the Class Principal Balance of Component II of the Class R Certificates. The “latest possible maturity date” (determined solely for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii)) for each REMIC II Regular Interest shall be the Maturity Date. None of the REMIC II Regular Interests will be certificated.

For federal income tax purposes, payment of any Carryover Shortfall Amount to any Class of Certificates and all payments to the Class XP Certificate (which shall not be treated as an interest in any REMIC, but as a pass-through interest in the Trust entitled to any prepayment penalties payable with respect to the Mortgage Loant) shall be treated as paid outside of any REMIC formed under this Agreement and shall not be part of the entitlement of the REMIC III Regular Interest related to the Class of Certificates receiving such payment.

Current Principal Amount of such Class on the Closing Date. On the Closing Date, the Trustee shall execute and countersign (i) in the case of each Class of Offered Certificates, the Certificate in the entire Current Principal Amount 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 Current Principal Amount of each such respective Class on the Closing Date. The Certificates referred to in clause (i) and if at any time there are to be Global Certificates, the Global Certificates shall be delivered by the Depositor to the Depository or pursuant to the Depository’s instructions, shall be delivered by the Depositor on behalf of the Depository to and deposited with the DTC Custodian.

(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 Trustee with an affidavit that the proposed transferee is a Permitted Transferee (and, unless the Tax Matters Person and the Seller consent to the transfer to a person who is not a U.S. Person, an affidavit that it is 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 Trustee 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 Trustee, 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 Trustee 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.

(c) Unless the Tax Matters Person shall have consented in writing (which consent may be withheld in the Tax Matters Person’s sole discretion), the Residual 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 Trustee 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 Trustee 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 Trustee may require an Opinion of Counsel addressed to the Trustee 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 Trustee 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 (a “Plan”) that is subject to

100

Title I of ERISA or Section 4975 of the Code, or by a person using “plan assets” of a Plan, unless the proposed transferee provides the Trustee, with an Opinion of Counsel addressed to the Servicer and the Trustee (upon which they may rely) that is satisfactory to the Trustee, which opinion will not be at the expense of the Servicer or the Trustee, 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 Servicer or the Trustee to any obligation in addition to those undertaken in this 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 Trustee, and any Person acquiring an interest in a Private Certificate in definitive form shall represent in writing to the Trustee, 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 B-1, Class B-2 or Class B-3 Certificate or any interest therein shall be deemed to have represented, by virtue of its acquisition or holding of that 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 Servicer nor the Trustee 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 Section s (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 Trustee and the Servicer from and against any and all liabilities, claims, costs or expenses incurred by the Trustee or the Servicer as a result of such attempted or purported transfer. The Trustee 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

101

and will be available for resales of such Private Certificates conducted in accordance with Rule 144A.

106

(E) 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 Loan Group 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 Senior Certificates, pro rata, based upon their Certificate Principal Balances, until all amounts due to all Classes of Senior Certificates have been paid in full, before any Available Funds are distributed in accordance with this clause to the Class R Certificates.

(F) On each Distribution Date prior to the Cross-Over Date, but after the reduction of the aggregate Current Principal Amount of all of the classes of any of the Group I Certificates, Group II Certificates, Group III Certificates or Group IV Certificates to zero, the remaining Certificate Groups will be entitled to receive in reduction of their Current Principal Amount, pro rata based upon aggregate Current Principal Amount of the Senior Certificates in each Certificate Group immediately prior to such Distribution Date, in addition to any Principal Prepayments related to such remaining Senior Certificates’ respective Loan Group allocated to such Senior Certificates, 100% of the Principal Prepayments on any Mortgage Loan in the Loan Group relating to any fully paid Certificate Group. Such amounts allocated to Senior Certificates shall be treated as part of the Available Funds for the related Loan Group and distributed as part of the related Senior Optimal Distribution Amount in accordance with priority fourth in clauses (A)(I) through (A)(IV) above, as applicable, in reduction of the Current Principal Amounts thereof. Notwithstanding the foregoing, if (i) the weighted average of the Subordinate Percentages on such Distribution Date equals or exceeds two times the initial weighted average of the Subordinate Percentages and (ii) the aggregate principal balance of the Mortgage Loans delinquent 60 days or more (including for this purpose any such Mortgage Loans in foreclosure and Mortgage Loans with respect to which the related mortgaged property has been acquired by the Trust), averaged over the last six months, as a percentage of the sum of the aggregate Current Principal Amount of the Subordinate Certificates does not exceed 100%, then the additional allocation of Principal Prepayments to the Senior Certificates in accordance with this paragraph (F) will not be made and 100% of the Principal Prepayments on any Mortgage Loan in the Loan Group relating to the fully paid Certificate Group will be allocated to the Subordinate Certificates on a pro rata basis.

(G) For any Undercollateralized Certificate Group on any Distribution Date prior to the Cross-Over Date, (i) 100% of amounts otherwise allocable to the Subordinate Certificates in respect of principal will be distributed to the Senior Certificates of such Undercollateralized Certificate Group on a pro rata basis in accordance with their respective Current Principal Amounts in reduction of the Current Principal Amounts

107

thereof, until the aggregate Current Principal Amounts of such Senior Certificates is an amount equal to the aggregate Scheduled Principal Balance of the Mortgage Loans in the related Loan Group and (ii) the Accrued Certificate Interest otherwise allocable to the Subordinate Certificates on such Distribution Date will be reduced and distributed to such Senior Certificates, to the extent of any amount due and unpaid on such 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 Subordinate Certificates will be allocated in reverse order of their respective numerical designations, 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 paragraph will be allocated between such Undercollateralized Certificate Groups, pro rata, based upon the amount by which their respective aggregate Current Principal Amounts exceed the aggregate Scheduled Principal Balance of the Mortgage Loans in their respective Loan Groups.

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

(c) If on any Distribution Date the Available Funds for the 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 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 Servicer or otherwise, except to the extent of applicable Compensating Interest Payments.

(d) The expenses and fees of the Trust shall be paid by each of the 2005-AR4 REMICs, to the extent that such expenses relate to the assets of each of such respective 2005-AR4 REMICs, and all other expenses and fees of the Trust shall be paid pro rata by each of the 2005-AR4 REMICs.

(e) On any Distribution Date, the Senior Percentage of the Net Deferred Interest for each Loan Group will be allocated to the related Certificate Group, on a pro rata basis, in accordance with the amount of interest accrued on such Class at its Pass-Through Rate for the Interest Accrual Period for such Distribution Date. The remainder of the Net Deferred Interest on each Loan Group will be allocated to the Class M Certificates and the Class B Certificates, on

108

a pro rata basis, in accordance with the amount of interest that accrued on such Class at its Pass-Through Rate for the Interest Accrual Period related to that Distribution Date.

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

fourteenth, to the Class of Senior Certificates in the related Certificate Group as described in Section 6.02(d) hereof.

(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) Subordinate Certificates to the extent that such allocation would result in the reduction of the aggregate Current Principal Amounts of all Certificates in as of such Distribution Date, after giving effect to all distributions and prior allocations of Realized Losses on the Mortgage Loans on such date, to an amount less than the aggregate Scheduled Principal Balance of all of the Mortgage Loans as of the first day of the month of such Distribution Date and (ii) Senior Certificates in a Certificate Group to the extent that such allocation would result in the reduction of the aggregate Current Principal Amounts of all the Certificates in such Certificate Group as of such Distribution Date, after giving effect to all distributions and prior allocations of Realized Losses on the Mortgage Loans in the related Loan Group on such date, to an amount less than the aggregate Scheduled Principal Balance of all of the Mortgage Loans in such Loan Group as of the first day of the month of such Distribution Date (such limitation described in clauses (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 Current Principal Amounts. The principal portion of any allocation of Realized Losses on the Group I Mortgage Loans allocated to the Senior Certificates of the Group I Certificates will be allocated on any Distribution Date concurrently and pro rata, to (i) the Class X-1 Certificates until the Current Principal Amount of such Class has been reduced to zero and (ii) first, the Class I-A-3 Certificates until the Current Principal Amount of such Class has been reduced to zero, second, the Class I-A-2b Certificates and the Class I-A-2a Certificates, pro rata, until the Current Principal Amounts of each such Class has been reduced to zero and, third, the Class I-A-1 Certificates until the Current Principal Amount of such Class has been reduced to zero. The principal portion of any allocation of Realized Losses on the Group II Mortgage Loans allocated to the Senior Certificates of the Group II Certificates will be allocated on any Distribution Date concurrently and pro rata, to (i) the Class X-2 Certificates until the Current Principal Amount of such Class has been reduced to zero and (ii) the Class II-A-2 Certificates and the Class II-A-1 Certificates, sequentially in that order, until the Current Principal Amount of each such Class thereof has been reduced to zero. The principal portion of Realized Losses on the Group III Mortgage Loans allocated to the Senior Certificates of the Group III Certificates will be allocated on any Distribution Date concurrently and pro rata, to (i) the Class X-3 Certificates until the Current Principal amount of such Class has been reduced to zero and (ii) the Class III-A-2 Certificates and the Class III-A-1 Certificates, sequentially in that order, until the Current Principal Amount of each such Class thereof has been reduced to zero. The principal portion of Realized Losses on the Group IV Mortgage Loans allocated to the Senior Certificates of the Group IV Certificates will be allocated on any Distribution Date concurrently and pro rata, to (i)

110

the Class X-4 Certificates until the Current Principal Amount of such Class has been reduced to zero and (ii) first, the Class IV-A-3 Certificates until the Current Principal Amount of such Class has been reduced to zero, second, the Class IV-A-2 Certificates until the Current Principal Amount of such Class has been reduced to zero and, third, the Class IV-A-1b Certificates and the Class IV-A-1a Certificates, pro rata, until the Current Principal Amounts of each such Class thereof have been reduced to zero.

(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 Trustee shall determine the Subordinate Certificate Writedown Amount. Any Subordinate Certificate Writedown Amount shall effect a corresponding reduction in the Current Principal Amount of the Subordinate Certificates in the reverse order of their numerical Class designations.

(g) The applicable Senior Percentage of Net Interest Shortfalls will be allocated among the Senior Certificates in the related 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 sequentially to the Class B Certificates and the Class M Certificates, beginning with the Class B Certificates with the highest numerical designation and then to the Class M Certificates with the highest numerical designation, in proportion to the amount of Accrued Certificate Interest that would have been allocated thereto in the absence of such shortfalls. If no Class B Certificates and Class M Certificates remain outstanding, the applicable Subordinate Percentage of Net Interest Shortfall will be allocated to the Class M-X Certificates. The interest portion of any Realized Losses with respect to the Mortgage Loans occurring on or prior to the Cross-Over Date will be allocated to the Subordinate Certificates in inverse order of their numerical Class designations. Following the Cross-Over Date, the interest portion of Realized Losses on the Mortgage Loans will be allocated to the Senior Certificates in the related 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 Servicer receives any Subsequent Recoveries on the Mortgage Loans, the Servicer shall deposit such funds into the Custodial Account pursuant to Section 4.01(a)(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 Current Principal Amount of the Class of 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 Subordinate Certificates pursuant to this Section 6.02. The amount of any remaining Subsequent Recoveries will be applied to sequentially increase the Current Principal Amount of the Subordinate Certificates, beginning with the Class of Subordinate Certificates with the next highest payment priority, up to the amount of such Realized Losses previously allocated to such Class or Classes of Certificates pursuant to this Section 6.02. 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

111

applied to the Current Principal Amount of each Subordinate Certificate of such Class in accordance with its respective Fractional Undivided Interest.

Section 6.03 Payments. (a) On each Distribution Date, other than the final Distribution Date, the Trustee 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 Trustee shall calculate the amount to be distributed to each Class and, based on such amounts, the Trustee shall determine the amount to be distributed to each Certificateholder. The Trustee’s calculations of payments shall be based solely on information provided to the Trustee by the Servicer. The Trustee 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 Trustee 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 Trustee specified in the notice to Certificateholders of such final payment.

Section 6.04 Statements to Certificateholders.

Section 6.05 Monthly Advances. If the interest portion of 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 exceeds the amount deposited in the Custodial Account which will be used for an advance with respect to such Mortgage Loan, the Servicer will deposit in the Custodial 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 Servicer determines any such advance to be a Nonrecoverable Advance. If the Servicer deems an advance to be a Nonrecoverable Advance, on the Distribution Account Deposit Date, the Servicer shall present an Officer’s Certificate to the Trustee (i) stating that the 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.

Notwithstanding the foregoing, the amount of such deposit may be reduced by the Amount Held for Future Distribution (as defined below) then on deposit in the Custodial Account. Any portion of the Amount Held for Future Distribution used to pay Monthly Advances shall be replaced by the Servicer by deposit into the Custodial Account on any future Distribution Account Deposit Date to the extent that the funds that are available in the Custodial Account on such Distribution Account Deposit Date are less than the amount of payments required to be made by the Servicer on such Distribution Account Deposit Date.

The “Amount Held for Future Distribution” as to any Distribution Account Deposit Date shall be the total of the amounts held in the Custodial Account at the close of business on the preceding Determination Date which were received after the Cut-off Date on account of (i) Liquidation Proceeds, Insurance Proceeds, and Principal Prepayments received or made in the month of such Distribution Account Deposit Date, and (ii) payments which represent early receipt of scheduled payments of interest due on a date or dates subsequent to the related Due Date.

Section 6.06 Compensating Interest Payments. The Servicer shall deposit in the Custodial 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 Servicer under this Agreement 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 (ii) the Servicing Fee for such Distribution Date (such amount, the “Compensating Interest Payment”). The Servicer shall not be entitled to any reimbursement of any Compensating Interest Payment. Compensating Interest Payments will be allocated to each Loan Group, on a pro rata basis, based on the respective amounts dtermined by clause (i) of this Section 6.06.

Section 6.07 Distributions on REMIC I Regular Interests, REMIC II Regular Interests and REMIC III Regular Interests

(a) On each Distribution Date, the Trustee shall be deemed to distribute to itself on behalf of REMIC II as the holder of the REMIC I Regular Interests, the following to the extent of the Available Funds reduced by distributions made to the Class R Certificateholders pursuant to Section 6.01(a): 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.

115

(b) On each Distribution Date, the Trustee shall be deemed to distribute to itself on behalf of REMIC III as the holder of the REMIC II Regular Interests, the following to the extent of the REMIC II Available Distributions Amount reduced by distributions made to the Class R Certificateholders in respect of Component I thereof pursuant to Section 6.01(a): 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 II Distribution Amount.

(c) On each Distribution Date the Trustee shall be deemed to distribute from REMIC II, in the priority set forth in Sections 6.01(a), to the Holders of each Class of Certificates (other than the Class R Certificates and the Class XP Certificates) the amounts distributable thereon with respect to their interests in REMIC III.

(d) Notwithstanding the deemed distributions on the REMIC I Regular Interests and REMIC II Regular Interests described in this Section 6.07, distributions of funds from the Certificate Account shall be made only in accordance with Section 6.01.

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

(a) The 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 or the Certificates or the powers of attorney delivered by the Trustee hereunder (i) related to the 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 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 Indemnified Person shall have given the Servicer and the Depositor written notice thereof promptly after the Indemnified Person 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 Indemnified Person’s right to indemnification hereunder, except to the extent the Servicer is materially prejudiced by such failure to give notice. This indemnity shall survive the resignation or removal of the Servicer or the Trustee 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 Servicer’s indemnification pursuant to Section 7.03(a).

117

(a) Neither the Servicer nor any of the directors, officers, employees or agents of the 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 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 Servicer and any director, officer, employee or agent of the 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 Servicer, the Custodian and any director, officer, employee or agent of the 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 or the Certificates, other than (i) any such loss, liability or expense related to the 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 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 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 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 Servicer shall be entitled to be reimbursed therefor out of the Custodial Account as provided by Section 4.02. Nothing in this Section 7.04(d) shall affect the Servicer’s obligation to service and administer the Mortgage Loans in accordance with this Agreement.

(e) In taking or recommending any course of action pursuant to this Agreement, unless specifically required to do so pursuant to this Agreement, the 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.

118

Section 7.05 Servicer Not to Resign. Except as provided in Section 7.07, the 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 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 Servicer shall become effective until the Trustee or a successor to the Servicer reasonably satisfactory to the Trustee shall have assumed the responsibilities and obligations of the Servicer in accordance with Section 8.02 hereof. The Trustee shall notify the Rating Agencies upon notice of the resignation of the Servicer.

Section 7.06 Successor Servicer. In connection with the appointment of any successor servicer or the assumption of the duties of the Servicer, the Depositor or the Trustee may make such arrangements for the compensation of such successor servicer out of payments on the Mortgage Loans as the Depositor or the Trustee and such successor servicer shall agree. If the successor servicer does not agree that such market value is a fair price, such successor 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 servicer may not exceed the compensation which the Servicer would have been entitled to retain if the Servicer had continued to act as Servicer hereunder.

Section 7.07 Sale and Assignment of Servicing. The Servicer may sell and assign its rights and delegate its duties and obligations in its entirety as Servicer under this Agreement and the Depositor may terminate the Servicer without cause and select a new 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 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 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 Servicer and the Trustee; (iii) the Servicer assigning and selling the 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 terms of this Agreement; and (iv) in the event the Servicer is terminated without cause by the Depositor, the Depositor shall pay the terminated Servicer a termination fee equal to 0.25% of the aggregate Scheduled Principal Balance of the Mortgage Loans at the time the servicing of the Mortgage Loans is transferred to the successor Servicer. No such assignment or delegation shall affect any rights or liability of the Servicer arising prior to the effective date thereof.

119

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 Servicer:

(i) The 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 Servicer; or

(ii) The 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 (or 15 days with respect to Sections 3.16, 3.17 or 3.18) after the date on which written notice of such failure, properly requiring the same to be remedied, shall have been given to the Servicer by the Trustee or to the Servicer and the Trustee by the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust Fund; or

(iii) There is entered against the 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 Servicer under any applicable insolvency or reorganization statute and the petition is not dismissed within 60 days after the commencement of the case; or

(iv) The 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 Servicer or substantially all of its property; or the 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;

(v) The 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; or

120

(vi) The 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 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 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 Servicer under this Agreement and in and to the Mortgage Loans and/or the REO Property serviced by the Servicer and the proceeds thereof. Upon the receipt by the Servicer of the written notice, all authority and power of the 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 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 Servicer agrees to cooperate with the Trustee in effecting the termination of the 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 Servicer reasonably requested by the Trustee to enable it to assume the 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 Servicer under this Agreement, the 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 Servicer shall not affect any obligations incurred by the 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 Servicer, which may be delivered by telecopy, immediately terminate all of the rights and obligations of the 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 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 Servicer of a notice of termination pursuant to Section 8.01 or an Opinion of Independent Counsel pursuant to Section 7.05 to the effect that the Servicer is legally unable to act or to

121

delegate its duties to a Person which is legally able to act, the Trustee shall automatically become the successor in all respects to the 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 Servicer by the terms and provisions hereof; 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 the Trustee or any other successor Servicer; and provided, further, that the Trustee shall have the right to select a successor 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 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 Servicer would have been entitled to retain if the Servicer had continued to act hereunder, except for those amounts due the 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 Servicer only, having a net worth of not less than $10,000,000, as the successor to the Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the 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 Servicer. Pending appointment of a successor to the 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 Servicer would have been entitled to if the 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 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 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 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 servicer.

(c) To the extent that the costs and expenses of the Trustee related to any termination of the Servicer, appointment of a successor Servicer or the transfer and assumption of servicing by the Trustee with respect to this 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 the Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including, but not

122

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 this Agreement) are not fully and timely reimbursed by the terminated Servicer, the Trustee shall be entitled to reimbursement of such costs and expenses from the Distribution Account.

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

Section 8.04 Waiver of Defaults. The Trustee 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 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 Trustee shall give notice of any such waiver 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 Trustee will afford such Certificateholders access during business hours to the most recent list of Certificateholders held by the Trustee.

123

Section 9.01

Duties of Trustee.

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Agreement as duties of the Trustee. 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.

(c) On each Distribution Date, the Trustee shall make monthly distributions and the final distribution to the Certificateholders from funds in the Distribution Account as provided in Sections 6.01 and 10.01 herein.

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

(i) 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 shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of its duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and, in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement;

(ii) The Trustee shall not 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, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(iii) The Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the directions of the Holders of

Section 9.02 Certain Matters Affecting the Trustee. Except as otherwise provided in Section 9.01:

(a) The Trustee may rely and shall be protected in acting or refraining from acting in reliance on any resolution, certificate of the Depositor or the Servicer, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) The Trustee may consult with counsel and any advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection with respect to any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

(c) The Trustee shall not be under any obligation to exercise any of the trusts or powers vested in it by this Agreement, other than its obligation to give notices pursuant to this Agreement, or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders pursuant to the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby. 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;

(d) Prior to the occurrence of an Event of Default hereunder and after the curing or waiver of all Events of Default which may have occurred, the Trustee shall not be liable in its individual capacity for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement;

(e) The Trustee shall not 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 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, reasonably assured to the Trustee, by the security afforded to it by the terms of this Agreement. The Trustee 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 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 Servicer, which consent will not be unreasonably

126

withheld. The Trustee shall not be liable or responsible for (i) the misconduct or negligence of any of the Trustee’s agents or attorneys or a custodian or paying agent appointed hereunder by the Trustee with due care and, when required, with the consent of the Servicer or (ii) any acts or omissions of the Servicer (unless the Trustee has assumed the obligations of the Servicer pursuant to the provision of this Agreement);

(g) Should the Trustee deem the nature of any action required on its part, other than a payment or transfer by the Trustee under Section 4.02, to be unclear, the Trustee may require prior to such action that it be provided by the Depositor with reasonable further instructions;

(h) The right of the Trustee to perform any discretionary act enumerated in this Agreement shall not be construed as a duty, and the Trustee shall not be accountable for other than its negligence or willful misconduct in the performance of any such act;

(i) The Trustee shall not be required to give any bond or surety with respect to the execution of the trust created hereby or the powers granted hereunder, except as provided in Section 9.07; and

(j) Neither the Trustee nor the Servicer shall have any duty to conduct any affirmative investigation as to the occurrence of any condition requiring the repurchase of any Mortgage Loan by the Seller pursuant to this Agreement, the Mortgage Loan Purchase Agreement or a Subsequent Mortgage Loan Purchase Agreement, as applicable, or the eligibility of any Mortgage Loan for purposes of this Agreement.

Section 9.03 Trustee Not Liable for Certificates or Mortgage Loans. The recitals contained herein and in the Certificates (other than the signature and countersignature of the Trustee on the Certificates) shall be taken as the statements of the Depositor, and the Trustee shall not have any responsibility for their correctness. The Trustee makes no representation as to the validity or sufficiency of the Certificates (other than the signature and countersignature of the Trustee 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 Trustee’s signature and countersignature (or countersignature of its agent) on the Certificates shall be solely in its capacity as Trustee and shall not constitute the Certificates an obligation of the Trustee in any other capacity. The Trustee shall not 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, the Trustee shall not 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. The Trustee shall not 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. The Trustee shall not have any responsibility for filing any financing or

127

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 3.19.

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

Section 9.05 Trustee’s Fees and Expenses. The Trustee will be entitled to all income and gain realized from any investment of funds in the Distribution Account, pursuant to Article IV, for the performance of its activities hereunder. In addition, the Trustee will be entitled to recover from the Distribution Account pursuant to Section 4.04 all reasonable out-of-pocket expenses, disbursements and advances and the expenses of the Trustee in connection with any Event of Default, any breach of this Agreement or any claim or legal action (including any pending or threatened claim or legal action) incurred or made by or against the Trustee or in connection with the administration of the trusts hereunder by the Trustee (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 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. The Trustee and any successor Trustee 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 Trustee 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. If the Trustee publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 9.06 the combined capital and surplus of such corporation shall be deemed to be its total equity capital (combined capital and surplus) as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 9.06, the Trustee shall resign immediately in the manner and with the effect specified in Section 9.08.

Section 9.07 Insurance. The Trustee, at its own expense, shall at all times maintain and keep in full force and effect: (i) fidelity insurance, (ii) theft of documents insurance and (iii) forgery insurance (which may be collectively satisfied by a “Financial Institution Bond” and/or a “Bankers’ Blanket Bond”). All such insurance shall be in amounts, with standard

128

coverage and subject to deductibles, as are customary for insurance typically maintained by banks or their affiliates which act as custodians for investor-owned mortgage pools. A certificate of an officer of the Trustee as to the Trustee’s compliance with this Section 9.07 shall be furnished to any Certificateholder upon reasonable written request.

Section 9.08

Resignation and Removal of the Trustee.

(a) The Trustee may at any time resign and be discharged from the Trust hereby created by giving written notice thereof to the Depositor and the Servicer, with a copy to the Rating Agencies. Upon receiving such notice of resignation, the Depositor shall promptly appoint a successor Trustee, by written instrument, in triplicate, one copy of which instrument shall be delivered to the resigning Trustee. If no successor Trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(b) If at any time the Trustee shall cease to be eligible in accordance with the provisions of Section 9.06 and shall fail to resign after written request therefor by the Depositor or if at any time the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Depositor shall promptly remove the Trustee and appoint a successor Trustee by written instrument, in triplicate, one copy of which instrument shall be delivered to the Trustee so removed, and the successor Trustee.

(c) The Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund may at any time remove the Trustee and appoint a successor Trustee by written instrument or instruments, in quintuplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered to the Depositor, the Servicer and the Trustee so removed and the successor so appointed. In the event that the Trustee 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, in excess of the amount paid hereunder to the predecessor Trustee.

(d) No resignation or removal of the Trustee and appointment of a successor Trustee 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 as provided in Section 9.09.

Section 9.09

Successor Trustee.

(a) Any successor Trustee appointed as provided in Section 9.08 shall execute, acknowledge and deliver to the Depositor and to its predecessor Trustee an instrument accepting such appointment hereunder. The resignation or removal of the predecessor Trustee shall then become effective and such successor Trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor

129

hereunder, with like effect as if originally named as Trustee herein. The predecessor Trustee shall, after its receipt of payment in full of its outstanding fees and expenses promptly deliver to the successor Trustee all assets and records of the Trust held by it hereunder, and the Depositor and the predecessor Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor Trustee all such rights, powers, duties and obligations.

(b) No successor Trustee shall accept appointment as provided in this Section 9.09 unless at the time of such acceptance such successor Trustee shall be eligible under the provisions of Section 9.06.

(c) Upon acceptance of appointment by a successor Trustee as provided in this Section 9.09, the successor Trustee shall mail notice of the succession of such Trustee hereunder to all Certificateholders at their addresses as shown in the Certificate Register and to the Rating Agencies. The Company shall pay the cost of any mailing by the successor Trustee.

Section 9.10 Merger or Consolidation of Trustee. Any state bank or trust company or national banking association into which the Trustee may be merged or converted or with which it may be consolidated or any state bank or trust company or national banking association resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any state bank or trust company or national banking association succeeding to all or substantially all of the corporate trust business of the Trustee shall be the successor of the Trustee hereunder, provided such state bank or trust company or national banking association shall be eligible under the provisions of Section 9.06. 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.

130

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

(g) No trustee under this Agreement shall be personally liable by reason of any act or omission of another trustee under this Agreement. The Depositor and the Trustee acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee.

Section 9.12 Federal Information Returns and Reports to Certificateholders; REMIC Administration; Grantor Trust Administration.

(a) For federal income tax purposes, the taxable year of each 2005-AR4 REMIC shall be a calendar year and the Trustee shall maintain or cause the maintenance of the books of each such 2005-AR4 REMIC on the accrual method of accounting.

(b) The Trustee shall prepare and file or cause to be filed with the Internal Revenue Service, and the Trustee shall upon the written instruction of the Trustee sign, Federal tax information returns or elections required to be made hereunder with respect to each 2005-AR4 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 Trustee shall furnish to each Holder of Certificates at any time during the calendar year for which such returns or reports are made such statements or information at the times and in the manner as may be required thereby, including, without limitation, reports relating to mortgaged

131

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 25% CPR). The Trustee 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 Trustee shall timely prepare and file, and the Trustee shall upon the written instruction of the Trustee 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 2005-AR4 REMIC (the “REMIC Reporting Agent”). The Trustee shall make elections to treat each 2005-AR4 REMIC as a REMIC (which elections shall apply to the taxable period ending December 31, 2005 and each calendar year thereafter) in such manner as the Code or applicable Treasury regulations may prescribe, and as described by the Trustee. The Trustee shall 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 Class R Certificates is hereby designated as the “Tax Matters Person” (within the meaning of Treas. Reg. §§1.860F-4(d)) for each 2005-AR4 REMIC. The Trustee 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 Trustee as agent and attorney-in-fact for the purpose of acting as Tax Matters Person for each 2005-AR4 REMIC during such time as the Trustee 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 Trustee from acting as agent for the Tax Matters Person, the Trustee shall take whatever action that in its 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 Trustee 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 Trustee shall prepare and file or cause to be filed, and the Trustee shall 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 Trustee shall comply with all federal withholding requirements respecting payments to Certificateholders of interest or original issue discount on the Mortgage Loans, that the Trustee reasonably believes are applicable under the Code. The consent of Certificateholders shall not be required for such withholding. In the event the Trustee withholds any amount from interest or original issue discount payments or advances thereof to any Certificateholder pursuant to federal withholding

132

requirements, the Trustee shall, together with its monthly report to such Certificateholders, indicate such amount withheld.

(f) The Trustee agrees 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 Servicer, as a result of a breach of the Trustee’s covenants set forth in this Section 9.12.

(g) The Trustee shall perform its obligations set forth under Section 7.12 of the Grantor Trust Agreement regarding the preparation and filing of tax returns for the Grantor Trust. The Trustee shall indemnify the Grantor Trust and the Seller for any taxes and costs including, without limitation, any attorneys fees imposed on or incurred by the Grantor Trust or the Depositor as a result of a breach of the Trustee’s obligations set forth under Section 7.12 of the Grantor Trust Agreement.

ARTICLE X

Termination

Section 10.01 Termination Upon Repurchase by the Depositor 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 and the Servicer created hereby, other than the obligation of the Trustee to make payments to Certificateholders as hereinafter set forth shall terminate upon:

(i) the repurchase by or at the direction of the Depositor or its designee of all of the Mortgage Loans and all related REO Property remaining in the Trust at a price (the “Termination Purchase Price”) equal to the sum of (a) 100% of the Outstanding Principal Balance of each Mortgage Loan (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 unpaid 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 Servicer, including unreimbursed servicing advances and the interest portion of any unreimbursed Monthly Advances, made on the Mortgage Loans 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 Servicer, the Custodian and the Trustee payable pursuant to Section 9.05 or Section 7.04(c);

(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.

134

(c) (i) The right of the Depositor or its designee to repurchase all the assets of the Trust Fund described in Section 10.01(a)(i) above shall be exercisable only if (i) the Scheduled Principal Balance of the Mortgage Loans at the time of any such repurchase is less than 10% of the sum of (x) the Cut-off Date Balance and (y) the Pre-Funded Amount or (ii) the Depositor, based upon an Opinion of Counsel addressed to the Depositor and the Trustee has determined that the REMIC status of any 2005-AR4 REMIC has been lost or that a substantial risk exists that such REMIC status will be lost for the then-current taxable year. At any time thereafter, in the case of (i) or (ii) above, the Depositor may elect to terminate any 2005-AR4 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 Trustee shall give notice of any termination to the Certificateholders, with a copy to the Servicer and the Rating Agencies, upon which the Certificateholders shall surrender their Certificates to the Trustee for payment of the final distribution and cancellation. Such notice shall be given by letter, mailed not earlier than the 15th 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 Trustee 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 Trustee therein specified.

(e) If the option of the Depositor to repurchase or cause the repurchase of all assets of the Trust Fund described in Section 10.01(a)(i) above is exercised, the Depositor and/or its designee shall deliver to the Trustee for deposit in the Distribution Account, by the Business Day prior to the applicable Distribution Date, an amount equal to the Termination Purchase Price. Upon presentation and surrender of the Certificates by the Certificateholders, the Trustee shall distribute to the Certificateholders from amounts then on deposit in the Distribution Account an amount determined as follows: with respect to each Certificate (other than the Class R Certificates and the Class XP Certificates), the outstanding Current Principal Amount, plus with respect to each Certificate (other than the Class R 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 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 Certificates (other than the Class R Certificates and the Class XP Certificates). If the proceeds with respect to the Mortgage Loans are not sufficient to pay all of the Certificates in full (other than the Class R Certificates and the Class XP Certificates), any such deficiency will be allocated first, to the Class B Certificates, and then to the Class M Certificates, in inverse order of their numerical designation, and then to the Senior Certificates, on a pro rata basis. Upon deposit of the required repurchase price and following such final Distribution Date, the Trustee shall release promptly (or cause the Custodian to release) to Depositor and/or its designee the Mortgage Files for the remaining applicable Mortgage Loans, and the Accounts with respect thereto shall terminate, subject to the Trustee’s obligation to hold any amounts payable to the Certificateholders in trust without interest pending final distributions pursuant to Section 10.01(g). Any other amounts remaining in the Accounts will belong to the Depositor.

135

(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, the Servicer shall deliver to the Trustee for deposit in the Distribution Account all distributable amounts remaining in the Custodial Account. Upon the presentation and surrender of the Certificates, the Trustee shall distribute to the remaining Certificateholders, in accordance with their respective interests, all distributable amounts remaining in the Distribution Account. Upon deposit by the Servicer of such distributable amounts, and following such final Distribution Date, the Trustee shall release promptly to the Depositor or its designee the Mortgage Files for the remaining Mortgage Loans, and the Custodial Account and the Distribution Account shall terminate, subject to the Trustee’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 Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice, not all the Certificates shall have been surrendered for cancellation, the Trustee 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.

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 2005-AR4 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 (which opinion shall not be at the expense of 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 2005-AR4 REMIC or (ii) cause any 2005-AR4 REMIC to fail to qualify as a 2005-AR4 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 Trustee, as agent for the respective Tax Matters Persons, shall adopt a plan of complete liquidation of each 2005-AR4 REMIC in the case of a termination under Section 10.01(a)(i). Such plan, which shall be provided to the Trustee by 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 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 Trustee 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 2005-AR4 REMIC and at or prior to the final Distribution Date, the Trustee shall sell

136

for cash all of the assets of the Trust to or at the direction of the Depositor, and each 2005-AR4 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 2005-AR4 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 2005-AR4 REMIC. Upon complete liquidation or final distribution of all of the assets of the Trust Fund, the Trust Fund and each 2005-AR4 REMIC shall terminate.

ARTICLE XI

Miscellaneous Provisions

Section 11.01 Intent of Parties. The parties intend that each 2005-AR4 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 Servicer, the Trustee, the Depositor, 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 2005-AR4 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 Servicer 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; provided, further, that with respect to clauses (iv) and (v) of this Section 11.02(a), the Trustee may request an Opinion of Independent Counsel, addressed to the Trustee (but not at the expense of the Trustee), to the effect that such amendment will not cause any REMIC created under this Agreement to fail to qualify as a REMIC at any time that any Certificate is outstanding.

(b) This Agreement may also be amended from time to time by the Company, the Servicer, the Depositor 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 2005-

138

AR4 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 the Depositor, the Servicer or the Trustee or any Affiliate thereof shall be entitled to vote their Fractional Undivided Interests with respect to matters affecting such Certificates.

(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 Trustee may prescribe.

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

139

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.

(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 Trustee, the Servicer or any successor to any such parties unless (i) such Certificateholder previously shall have given to the Trustee 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 Trustee 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 Trustee 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 Trustee deems sufficient.

140

(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 none of the Trustee, the Depositor, the Servicer nor any successor to any such parties shall be affected by any notice to the contrary.

(d) 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 Depositor, the 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 Depositor, the 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 Depositor, the 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 Depositor, or the Servicer, as the case may be.

                             CALCULATION OF REMIC I Y PRINCIPAL REDUCTION AMOUNTS


 REMIC I Y Principal Reduction Amounts:  For any Distribution Date the amounts by which the Uncertificated
Principal Balances of the REMIC I Regular Interests Y-1, Y-2, Y-3 and Y-4, respectively, will be reduced on
such Distribution Date by the allocation of Realized Losses and the distribution of principal, determined as
follows:

First, for each of Loan Group I, Loan Group II, Loan Group III and Loan Group IV, determine the weighted
average of the Net Mortgage Rates on Mortgage Loans in the applicable Loan Group (for such Loan Group, its
"Weighted Average Adjusted Net Mortgage Rate") for distributions of interest that will be made on the next
succeeding Distribution Date (the "Group Interest Rate").  The Principal Reduction Amount for each of the
REMIC I Y Certificates will be determined pursuant to the "Generic solution for the REMIC I Y Principal
Reduction Amounts" set forth below (the "Generic Solution") by making identifications among the actual Groups
and their related REMIC I Y and Z Regular Interests and the Weighted Average Adjusted Net Mortgage Rates and
the Groups named in the Generic Solution and their related REMIC I Y and Z Regular Interests as follows:

A.  Determine which Group has the lowest Group Interest Rate.  That Group will be identified with Group AA
and the REMIC I Y and Z Regular Interests related to that Group will be respectively identified with the
REMIC I YAA and ZAA Regular Interests.  The Group Interest Rate for that Group will be identified with J%.
If two or more Groups have the lowest Group Interest Rate pick one for this purpose, subject to the
restriction that each Group may be picked only once in the course of any such selections pursuant to
paragraphs A through D of this definition.

B. Determine which Group has the second lowest Group Interest Rate.  That Group will be identified with
Group BB and the REMIC I Y and Z Regular Interests related to that Group will be respectively identified with
the REMIC I YBB and ZBB Regular Interests.  The Group Interest Rate for that Group will be identified with
K%.  If two or more Groups have the second lowest Group Interest Rate pick one for this purpose, subject to
the restriction that each Group may be picked only once in the course of any such selections pursuant to
paragraphs A through D of this definition.

C.  Determine which Group has the third lowest Group Interest Rate.  That Group will be identified with
Group CC and the REMIC I Y and Z Regular Interests related to that Group will be respectively identified with
the REMIC I YCC and ZCC Regular Interests.  The Group Interest Rate for that Group will be identified with
L%.  If two or more Groups have the third lowest Group Interest Rate pick one for this purpose, subject to
the restriction that each Group may be picked only once in the course of any such selections pursuant to
paragraphs A through D of this definition.

D.  Determine which Group has the fourth lowest Group Interest Rate.  That Group will be identified with
Group DD and the REMIC I Y and REMIC I Z Regular Interests related to that Group will be respectively
identified with the REMIC I YDD and REMIC I ZDD Regular Interests.  The Group Interest Rate for that Group
will be identified with M%.  If two or more Groups have the fourth lowest Group Interest Rate pick one for
this purpose, subject to the restriction that each Group may be picked only once in the course of any such
selections pursuant to paragraphs A through D of this definition.

Second, apply the Generic Solution set forth below to determine the REMIC I Y Principal Reduction Amounts for
the Distribution Date using the identifications made above.

 Generic Solution for the REMIC I Y Principal Reduction Amounts:  For any Distribution Date, the amounts by
which the Uncertificated Principal Balances of the REMIC I YAA, YBB, YCC and YDD Regular Interests
respectively will be reduced on such Distribution Date by the allocation of Realized Losses and the
distribution of principal, determined as follows:

For purposes of the succeeding formulas the following symbols shall have the meanings set forth below:

        Realized Losses and distributions of principal to be made on such Distribution Date
    =  J%

             = {K% (Pk - ΔPk) + L% (Pl - ΔPl) + M% (Pm - ΔPm) + N% (Pn - ΔPn) }/
                      ( Pk - ΔPk + Pl - ΔPl + Pm - ΔPm + Pn - ΔPn )

r11 =   the weighted average of the REMIC I YAA, YBB, YCC and YDD Pass-Through Rates
     =  (J% Yj + K% Yk + L% Yl + M% Ym )/(Yj + Yk + Yl + Ym )

r12 =   the REMIC I YEE Pass-Through Rate
     =  N%

The purpose of the foregoing definitional provisions together with the related provisions allocating Realized
Losses and defining the REMIC I Y and REMIC I Z Principal Distribution Amounts is to accomplish the following
goals in the following order of priority:

1. Making the ratio of (Yn - ΔYn ) to (Y11 - ΔY11 ) equal to γ1 after taking account of the allocation
    Realized Losses and the distributions that will be made through the end of the Distribution Date to which
    such provisions relate and assuring that the Principal Reduction Amount for each of the REMIC I YAA, YBB,
    YCC, YDD, ZAA, ZBB, ZCC and ZDD Regular Interests is greater than or equal to zero for such Distribution
    Date;
2. Making the REMIC I YAA Uncertificated Principal Balance less than or equal to 0.0005 of the sum of the
    REMIC I YAA and REMIC I ZAA Uncertificated Principal Balances, the REMIC I YBB Uncertificated Principal
    Balance less than or equal to 0.0005 of the sum of the REMIC I YBB and REMIC I ZBB Uncertificated
    Principal Balances, the REMIC I YCC Uncertificated Principal Balance less than or equal to 0.0005 of the
    sum of the REMIC I YCC and REMIC I ZCC Uncertificated Principal Balances, the REMIC I YDD Uncertificated
    Principal Balance less than or equal to 0.0005 of the sum of the REMIC I YDD and REMIC I ZDD
    Uncertificated Principal Balances in each case after giving effect to allocations of Realized Losses and
    distributions to be made through the end of the Distribution Date to which such provisions relate; and
3. Making the larger of (a) the fraction whose numerator is (Yn - ΔYn ) and whose denominator is the sum of
    (Yn - ΔYn) and (Zn - ΔZn) and (b) the fraction whose numerator is (Y11 - ΔY11) and whose denominator is
    the sum of (Y11 - ΔY11) and (Z11 - ΔZ11) as large as possible while remaining less than or equal to
    0.0005.

In the event of a failure of the foregoing portion of the definition of REMIC I Y Principal Reduction Amount
to accomplish both of goals 1 and 2 above, the amounts thereof should be adjusted to so as to accomplish such
goals within the requirement that each REMIC I Y Principal Reduction Amount must be less than or equal to the
sum of (a) the Principal Realized Losses to be allocated on the related Distribution Date for the related
Pool remaining after the allocation of such Realized Losses to the related class of ratio-strip principal
only certificates, if any, and (b) the remainder of the Available Distribution Amount for the related Pool or
after reduction thereof by the distributions to be made on such Distribution Date (i) to the related class of
ratio-strip principal only certificates, if any, (ii) to the related class of ratio-strip interest only
certificates, if any, and (iii) in respect of interest on the related REMIC I Y and REMIC I Z Certificates,
or, if both of such goals cannot be accomplished within such requirement, such adjustment as is necessary
shall be made to accomplish goal 1 within such requirement.  In the event of any conflict among the
provisions of the definition of the REMIC I Y Principal Reduction Amounts, such conflict shall be resolved on
the basis of the goals and their priorities set forth above within the requirement set forth in the preceding
sentence.  If the formula allocation of ΔY11 among ΔYj, ΔYk, ΔYl and ΔYm cannot be achieved because one or
more of ΔYj, ΔYk, ΔYl and ΔYm, as so defined is greater than the related one of ΔPj, ΔPk, ΔPl and ΔPm, such
an allocation shall be made as close as possible to the formula allocation within the requirement that
ΔYj < ΔPj, ΔYk < ΔPk, ΔYl < ΔPl, ΔYm < ΔPm and ΔYm < ΔPm.

The purpose of the foregoing definitional provisions together with the related provisions allocating Realized
Losses and defining the REMIC I Y and REMIC I Z Principal Distribution Amounts is to accomplish the following
goals in the following order of priority:

1. Making the ratio of (Y22 - ΔY22 ) to (Y21 - ΔY21 ) equal to γ2 after taking account of
    the allocation Realized Losses and the distributions that will be made through the end of the
    Distribution Date to which such provisions relate and assuring that the Principal Reduction Amount for
    each of the REMIC I YAA, YBB, YCC, YDD, ZAA, ZBB, ZCC and ZDD Regular Interests is greater than or equal
    to zero for such Distribution Date;
2. Making the REMIC I YAA Uncertificated Principal Balance less than or equal to 0.0005 of the sum of the
    REMIC I YAA and REMIC I ZAA Uncertificated Principal Balances, the REMIC I YBB Uncertificated Principal
    Balance less than or equal to 0.0005 of the sum of the REMIC I YBB and REMIC I ZBB Uncertificated
    Principal Balances, the REMIC I YCC Uncertificated Principal Balance less than or equal to 0.0005 of the
    sum of the REMIC I YCC and REMIC I ZCC Uncertificated Principal Balances and the REMIC I YDD
    Uncertificated Principal Balance less than or equal to 0.0005 of the sum of the REMIC I YDD and REMIC I
    ZDD Uncertificated Principal Balances, in each case after giving effect to allocations of Realized Losses
    and distributions to be made through the end of the Distribution Date to which such provisions relate;
    and
3. Making the larger of (a) the fraction whose numerator is (Y22 - ΔY22 ) and whose denominator is the
    sum of (Y22 - ΔY22) and (Z22 - ΔZ22) and (b) the fraction whose numerator is (Y21 -
    ΔY21) and whose denominator is the sum of (Y21 - ΔY21) and (Z21 - ΔZ21) as large as
    possible while remaining less than or equal to 0.0005.

In the event of a failure of the foregoing portion of the definition of REMIC I Principal Reduction Amount to
        accomplish both of goals 1 and 2 above, the amounts thereof should be adjusted to so as to accomplish
        such goals within the requirement that each REMIC I Y Principal Reduction Amount must be less than or
        equal to the sum of (a) the Principal Realized Losses to be allocated on the related Distribution Date
        for the related Pool remaining after the allocation of such Realized Losses to the related class of
        ratio-strip principal only certificates, if any, and (b) the remainder of the Available Distribution
        Amount for the related Pool or after reduction thereof by the distributions to be made on such
        Distribution Date (i) to the related class of ratio-strip principal only certificates, if any, (ii) to
        the related class of ratio-strip interest only certificates, if any, and (iii) in respect of interest
        on the related REMIC I Y and REMIC I Z Regular Interests, or, if both of such goals cannot be
        accomplished within such requirement, such adjustment as is necessary shall be made to accomplish goal
        1 within such requirement.  In the event of any conflict among the provisions of the definition of the
        REMIC I Y Principal Reduction Amounts, such conflict shall be resolved on the basis of the goals and
        their priorities set forth above within the requirement set forth in the preceding sentence.  If the

        ΔYm and ΔYn, as so defined, is greater than the related one of ΔPj, ΔPk,
        ΔPl, ΔPm and ΔPn, such an allocation shall be made as close as possible to the

    allocation Realized Losses and the distributions that will be made through the end of the Distribution
    Date to which such provisions relate and assuring that the Principal Reduction Amount for each of the
    REMIC I YAA, YBB, YCC, YDD, ZAA, ZBB, ZCC and ZDD Regular Interests is greater than or equal to zero for
    such Distribution Date;
2. Making the REMIC I YAA Uncertificated Principal Balance less than or equal to 0.0005 of the sum of the
    REMIC I YAA and REMIC I ZAA Uncertificated Principal Balances, the REMIC I YBB Uncertificated Principal
    Balance less than or equal to 0.0005 of the sum of the REMIC I YBB and REMIC I ZBB Uncertificated
    Principal Balances, the REMIC I YCC Uncertificated Principal Balance less than or equal to 0.0005 of the
    sum of the REMIC I YCC and REMIC I ZCC Uncertificated Principal Balances and the REMIC I YDD
    Uncertificated Principal Balance less than or equal to 0.0005 of the sum of the REMIC I YDD and REMIC I
    ZDD Uncertificated Principal Balances, in each case, after giving effect to allocations of Realized
    Losses and distributions to be made through the end of the Distribution Date to which such provisions
    relate; and
3. Making the larger of (a) the fraction whose numerator is (Y42 - ΔY42 ) and whose denominator is the
    sum of (Y42 - ΔY42) and (Z42 - ΔZ42) and (b) the fraction whose numerator is (Yj - ΔYj)
    and whose denominator is the sum of (Yj - ΔYj) and (Zj - ΔZj) as large as possible while
    remaining less than or equal to 0.0005.

In the event of a failure of the foregoing portion of the definition of REMIC I Y Principal Reduction Amount
to accomplish both of goals 1 and 2 above, the amounts thereof should be adjusted to so as to accomplish such
goals within the requirement that each REMIC I Y Principal Reduction Amount must be less than or equal to the
sum of (a) the Principal Realized Losses to be allocated on the related Distribution Date for the related
Pool remaining after the allocation of such Realized Losses to the related class of ratio-strip principal
only certificates, if any, and (b) the remainder of the Available Distribution Amount for the related Pool or
after reduction thereof by the distributions to be made on such Distribution Date (i) to the related class of
ratio-strip principal only certificates, if any, (ii) to the related class of ratio-strip interest only
certificates, if any, and (iii) in respect of interest on the related REMIC I Y and REMIC I Z Regular
Interests, or, if both of such goals cannot be accomplished within such requirement, such adjustment as is
necessary shall be made to accomplish goal 1 within such requirement.  In the event of any conflict among the
provisions of the definition of the REMIC I Y Principal Reduction Amounts, such conflict shall be resolved on
the basis of the goals and their priorities set forth above within the requirement set forth in the preceding
sentence.  If the formula allocation of ΔY42 among ΔYk, ΔYl, ΔYm and ΔYn cannot
be achieved because one or more of ΔYk, ΔYl, ΔYm and ΔYn, as so defined, is greater
than the related one of ΔPk, ΔPl, ΔPm and ΔPn, such an allocation shall be made as
close as possible to the formula allocation within the requirement that ΔYk < ΔPk, ΔYl <
ΔPl, ΔYm < ΔPm and ΔYn < ΔPn.

NOTES:

1. REMIC I YAA and ZAA Regular Interests are related to Loan Group AA.  The sum of the Uncertificated
Principal Balances for the REMIC I YAA and ZAA Regular Interests is equal to the aggregate stated principal
balance of the Mortgage Loans in Loan Group AA.  REMIC I YBB and ZBB Regular Interests are related to Loan
Group BB.  The sum of the Uncertificated Principal Balances for the REMIC I YBB and REMIC I ZBB Regular
Interests is equal to the aggregate stated principal balance of the Mortgage Loans in Loan Group BB.  REMIC I
YCC and ZCC  Regular Interests are related to Loan Group CC.  The sum of the Uncertificated Principal
Balances for the REMIC I YCC and ZCC Regular Interests is equal to the aggregate stated principal balance of
the Mortgage Loans in Loan Group CC.  REMIC I YDD and ZDD Regular Interests are related to Loan Group DD.
The sum of the Uncertificated Principal Balances for the REMIC I YDD and ZDD Regular Interests is equal to
the aggregate stated principal balance of the Mortgage Loans in Loan Group DD.  The REMIC I Y and Z Regular
Interests will be principal and interest classes bearing interest at the pass-through rate for the related
Loan Group.

2. The Class CB pass-through rate is the weighted average of the pass-through rates on the REMIC I YAA, YBB,
YCC, and YDD Regular Interests.

MORTGAGE PASS-THROUGH CERTIFICATE

SERIES 2005-AR4

evidencing a fractional undivided interest in the distributions allocable to the Class [I][II][III][IV]-A-[1][2][3] Certificates with respect to a Trust Fund consisting primarily of a pool of adjustable interest rate mortgage loans secured by first liens on one-to-four family residential properties (the “Mortgage Loans”) and sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

This Certificate is payable solely from the assets of the Trust Fund, and does not represent an obligation of or interest in Structured Asset Mortgage Investments II Inc. ("SAMI II"), the Servicer or the Trustee referred to below or any of their affiliates or any other person. Neither this Certificate nor the underlying Mortgage Loans are guaranteed or insured by any governmental entity or by SAMI II, the Servicer or the Trustee or any of their affiliates or any other person. None of SAMI II, the Servicer or any of their affiliates will have any obligation with respect to any certificate or other obligation secured by or payable from payments on the Certificates.

This certifies that Cede & Co. is the registered owner of the Fractional Undivided Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in a trust (the “Trust Fund”) primarily consisting of the Mortgage Loans sold by SAMI II. The Mortgage Loans were sold by EMC Mortgage Corporation (“EMC”) to SAMI II. EMC will act as servicer of the Mortgage Loans (the “Servicer,” which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”), among SAMI II, as depositor (the “Seller”), EMC and Wells Fargo Bank, National Association, as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Interest on this Certificate will accrue during the period from and including the preceding Distribution Date (as hereinafter defined) (or in the case of the first Distribution Date, from the Closing Date) to and including the day prior to the current Distribution Date on the Current Principal Amount hereof at a per annum rate equal to the Pass-Through Rate set forth in the Agreement. The Trustee will distribute on the 25th day of each month, or, if such 25th day is not a Business Day, the immediately following Business Day (each, a “Distribution Date”), commencing on the first Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the Business Day immediately preceding the related Distribution Date so long as such Certificate remains in book-entry form (and otherwise, the close of business on the last Business Day of the month immediately preceding the month of such Distribution Date), an amount equal to the product of the Fractional Undivided Interest evidenced by this Certificate and the amount (of interest, if any) required to be distributed to the Holders of Certificates of the same Class as this Certificate. The Assumed Final Distribution Date is the Distribution Date in the month following the latest scheduled maturity date of any Mortgage Loan and is not likely to be the date on which the Current Principal Amount of this Class of Certificates will be reduced to zero.

Distributions on this Certificate will be made by the Trustee by check mailed to the address of the Person entitled thereto as such name and address shall appear on the Certificate Register or, if such Person so requests by notifying the Trustee in writing as specified in the Agreement, by wire transfer. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Trustee for that purpose and designated in such notice. The initial Current Principal Amount of this Certificate is set forth above. The Current Principal Amount hereof will be reduced to the extent of distributions allocable to principal hereon and Realized Losses allocated hereto and will be increased to the extent of Net Deferred Interest allocated thereto, in each case, as set forth in the Agreement.

This Certificate is one of a duly authorized issue of Certificates designated as set forth on the face hereof (the “Certificates”). The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

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

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

The Agreement permits, with certain exceptions therein provided: (i) the amendment thereof and the modification of the rights and obligations of the Seller, the Servicer and the Trustee and the rights of the Certificateholders under the Agreement from time to time by the Seller, the Servicer and the Trustee, and (ii) the amendment thereof by the Servicer 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 in certain cases, Holders of Certificates of affected Classes evidencing such percentage of the Fractional Undivided Interests thereof). Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate will be registered with the Trustee upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Trustee for such purposes, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Trustee duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates in authorized denominations representing a like aggregate Fractional Undivided Interest will be issued to the designated transferee.

The Certificates are issuable only as registered Certificates without coupons in the Classes and denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for one or more new Certificates evidencing the same Class and in the same aggregate Fractional Undivided Interest, as requested by the Holder surrendering the same.

No service charge will be made to the Certificateholders for any such registration of transfer, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Seller, the Servicer, the Trustee and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Seller, the Servicer, the Trustee or any such agent shall be affected by notice to the contrary.

Fund and disposition of all property acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the remittance of all funds due under the Agreement, or (ii) the optional repurchase by the party named in the Agreement of all the Mortgage Loans and other assets of the Trust Fund in accordance with the terms of the Agreement. Such optional repurchase may be made only if (i) the Scheduled Principal Balance of the Mortgage Loans at the time of any such repurchase is less than 10% of the sum of (x) the Cut-off Date Balance and (y) the Pre-Funded Amount or (ii) the Depositor, based upon an Opinion of Counsel addressed to the Depositor and the Trustee has determined that the REMIC status of any REMIC under the Agreement has been lost or that a substantial risk exists that such REMIC status will be lost for the then-current taxable year. The exercise of such right will effect the early retirement of the Certificates. In no event, however, will the Trust Fund created by the Agreement continue beyond the expiration of 21 years after the death of certain persons identified in the Agreement.

Unless this Certificate has been countersigned by an authorized signatory of the Trustee by manual signature, this Certificate shall not be entitled to any benefit under the Agreement, or be valid for any purpose.

IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly executed.

evidencing a fractional undivided interest in the distributions allocable to the Class B-[1][2][3] Certificates with respect to a Trust Fund consisting primarily of a pool of adjustable interest rate mortgage loans secured by first liens on one-to-four family residential properties (the “Mortgage Loans”) and sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

This Certificate is payable solely from the assets of the Trust Fund, and does not represent an obligation of or interest in Structured Asset Mortgage Investments II Inc. (“SAMI II”), the Servicer or the Trustee referred to below or any of their affiliates or any other person. Neither this Certificate nor the underlying Mortgage Loans are guaranteed or insured by any governmental entity or by SAMI II, the Servicer or the Trustee or any of their affiliates or any other person. None of SAMI II, the Servicer or any of their affiliates will have any obligation with respect to any certificate or other obligation secured by or payable from payments on the Certificates.

Interest on this Certificate will accrue during the period from and including the preceding Distribution Date (as hereinafter defined) (or in the case of the first Distribution Date, from the Closing Date) to and including the day prior to the current Distribution Date on the Current Principal Amount hereof at a per annum rate equal to the Pass-Through Rate set forth in the Agreement. The Trustee will distribute on the 25th day of each month, or, if such 25th day is not a Business Day, the immediately following Business Day (each, a “Distribution Date”), commencing on the first Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the Business Day immediately preceding the related Distribution Date so long as such Certificate remains in book-entry form (and otherwise, the close of business on the last Business Day of the month immediately preceding the month of such Distribution Date), an amount equal to the product of the Fractional Undivided Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Certificates of the same Class as this Certificate. The Assumed Final Distribution Date is the Distribution Date in the month following the latest scheduled maturity date of any Mortgage Loan and is not likely to be the date on which the Current Principal Amount of this Class of Certificates will be reduced to zero.

Each beneficial owner of a Class B-[1][2][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 and Moody's, (ii) it is not a Plan or investing with “plan assets” of any Plan, (iii)(1) it is an

evidencing a fractional undivided interest in the distributions allocable to the Class R Certificates with respect to a Trust Fund consisting primarily of a pool of adjustable interest rate mortgage loans secured by first liens on one-to-four family residential properties (the “Mortgage Loans”) and sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

This certifies that Bear, Stearns Securities Corp. is the registered owner of the Fractional Undivided Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in a trust (the “Trust Fund”) primarily consisting of the Mortgage Loans sold by SAMI II. The Mortgage Loans were sold by EMC Mortgage Corporation (“EMC”) to SAMI II. EMC will act as servicer of the Mortgage Loans (the “Servicer,” which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”), among SAMI II, as depositor (the “Seller”), EMC and Wells Fargo Bank, National Association, as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Each Holder of this Certificate will be deemed to have agreed to be bound by the restrictions set forth in the Agreement to the effect that (i) each person holding or acquiring any ownership interest in this Certificate must be a United States Person and a Permitted Transferee, (ii) the transfer of any ownership interest in this Certificate will be conditioned upon the delivery to the Trustee of, among other things, an affidavit to the effect that it is a United States Person and Permitted Transferee, (iii) any attempted or purported transfer of any ownership interest in this Certificate in violation of such restrictions will be absolutely null and void and will vest no rights in the purported transferee, and (iv) if any person other than a United States Person and a Permitted Transferee acquires any ownership interest in this Certificate in violation of such restrictions, then the Seller will have the right, in its sole discretion and without notice to the Holder of this Certificate, to sell this Certificate to a purchaser selected by the Seller, which purchaser may be the Seller, or any affiliate of the Seller, on such terms and conditions as the Seller may choose.

The Trustee will distribute on the 25th day of each month, or, if such 25th day is not a Business Day, the immediately following Business Day (each, a “Distribution Date”), commencing on the first Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month of the related Distribution Date, an amount equal to the product of the Fractional Undivided Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Certificates of the same Class as this Certificate. The Assumed Final Distribution Date is the Distribution Date in the month following the latest scheduled maturity date of any Mortgage Loan and is not likely to be the date on which the Current Principal Amount of this Class of Certificates will be reduced to zero.

No transfer of this Certificate shall be made unless the transfer is made pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “1933 Act”), and an effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification. In the event that such a transfer of this Certificate is to be made without registration or qualification, the Trustee shall require receipt of (i) if such transfer is purportedly being made (a) in reliance upon Rule 144A under the 1933 Act or (b) to a transferee that is an “Institutional Accredited Investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the 1933 Act, written certifications from the Holder of the Certificate desiring to effect the transfer, and from such Holder’s prospective transferee, substantially in the forms attached to the Agreement as Exhibit F-1 or F-2, as applicable, and (ii) if requested by the Trustee, an Opinion of Counsel satisfactory to it that such transfer may be made without such registration or qualification (which Opinion of Counsel shall not be an expense of the Trust Fund or of the Seller or the Trustee in their respective capacities as such), together with copies of the written certification(s) of the Holder of the Certificate desiring to effect the transfer and/or such Holder’s prospective transferee upon which such Opinion of Counsel is based. Neither the Seller nor the Trustee is obligated to register or qualify the Class of Certificates specified on the face hereof under the 1933 Act or any other securities law or to take any action not otherwise required under the Agreement to permit the transfer of such Certificates without registration or qualification. Any Holder desiring to effect a transfer of this Certificate shall be required to indemnify the Trustee and the Seller against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of this Class R Certificate will be made unless the Trustee has received either (i) opinion of counsel for the benefit of the Trustee and the Servicer and which they may rely which is satisfactory to the Trustee that the purchase of this certificate is permissible under local law, will not constitute or result in a non-exempt prohibited transaction under Section 406 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and Section 4975 of the Internal Revenue Code, as amended (the “Code”) and will not subject the Servicer or the Trustee to any obligation or liability in addition to those undertaken in the Agreement or (ii) a representation letter stating that the transferee is not acquiring directly or indirectly by, or on behalf of, an employee benefit plan or other retirement arrangement (a "Plan") that is subject to Title I of ERISA, and/or Section 4975 of the Code, or by a person using "plan assets" of a Plan.

No service charge will be made to the Certificateholders for any such registration of transfer, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Seller, the Servicer, the Trustee and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Seller, the Trustee or any such agent shall be affected by notice to the contrary.

the then-current taxable year. The exercise of such right will effect the early retirement of the Certificates. In no event, however, will the Trust Fund created by the Agreement continue beyond the expiration of 21 years after the death of certain persons identified in the Agreement.

IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly executed.

Affidavit pursuant to Section 860E(e)(4) of the Internal Revenue Code of 1986, as amended, and for other purposes

STATE OF	)
	) ss:
COUNTY OF	)

[NAME OF OFFICER], being first duly sworn, deposes and says:

1. That he is [Title of Officer] of [Name of Investor] (record or beneficial owner of the GreenPoint Mortgage Funding Trust 2005-AR4, Mortgage Pass-Through Certificates, Series 2005-AR4, Class R Certificates) (the “Class R Certificates”) (the A Owner@), a [savings institution] [corporation] duly organized and existing under the laws of [the State of _____] [the United States], on behalf of which he makes this affidavit.

2. That the Owner (i) is not and will not be as of [Closing Date][date of purchase] a “disqualified organization” within the meaning of Section 860E(e)(5) of the Internal Revenue Code of 1986, as amended (the “Code”) or an “electing large partnership” within the meaning of Section 775 of the Code, (ii) will endeavor to remain other than a disqualified organization and an electing large partnership for so long as it retains its ownership in the Class R Certificates and (iii) is acquiring the Class R Certificates for its own account or for the account of another Owner from which it has received an affidavit and agreement in substantially the same form as this affidavit and agreement. (For this purpose, a “disqualified organization” means an electing large partnership under Section 775 of the Code, the United States, any state or political subdivision thereof, any agency or instrumentality of any of the foregoing (other than an instrumentality all of the activities of which are subject to tax and, except for the Federal Home Loan Mortgage Corporation, a majority of whose board of directors is not selected by any such governmental entity) or any foreign government, international organization or any agency or instrumentality of such foreign government or organization, any rural electric or telephone cooperative, or any organization (other than certain farmers’ cooperatives) that is generally exempt from federal income tax unless such organization is subject to the tax on unrelated business taxable income).

3. That the Owner is aware (i) of the tax that would be imposed on transfers of Class R Certificates to disqualified organizations or electing large partnerships under the Code, that applies to all transfers of Class R Certificates after March 31, 1988; (ii) that such tax would be on the transferor (or, with respect to transfers to electing large partnerships, on each such partnership), or, if such transfer is through an agent (which person includes a broker, nominee or middleman) for a disqualified organization, on the agent; (iii) that the person (other than with respect to transfers to electing large partnerships) otherwise liable for the tax shall be relieved of liability for the tax if the transferee furnishes to such person an affidavit that the transferee is not a disqualified organization and, at the time of transfer, such person does not have actual

knowledge that the affidavit is false; and (iv) that the Class R Certificates may be “noneconomic residual interests” within the meaning of Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax.

4. That the Owner is aware of the tax imposed on a “pass-through entity” holding Class R Certificates if either the pass-through entity is an electing large partnership under Section 775 of the Code or if at any time during the taxable year of the pass-through entity a disqualified organization is the record holder of an interest in such entity. (For this purpose, a “pass through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives.)

5. That the Owner is aware that the Trustee will not register the transfer of any Class R Certificates unless the transferee, or the transferee’s agent, delivers to it an affidavit and agreement, among other things, in substantially the same form as this affidavit and agreement. The Owner expressly agrees that it will not consummate any such transfer if it knows or believes that any of the representations contained in such affidavit and agreement are false.

6. That the Owner has reviewed the restrictions set forth on the face of the Class R Certificates and the provisions of Section 5.05 of the Pooling and Servicing Agreement under which the Class R Certificates were issued. The Owner expressly agrees to be bound by and to comply with such restrictions and provisions.

7. That the Owner consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute a reasonable arrangement to ensure that the Class R Certificates will only be owned, directly or indirectly, by an Owner that is not a disqualified organization.

8.	The Owner’s Taxpayer Identification Number is # _______________.

9. This affidavit and agreement relates only to the Class R Certificates held by the Owner and not to any other holder of the Class R Certificates. The Owner understands that the liabilities described herein relate only to the Class R Certificates.

10. That no purpose of the Owner relating to the transfer of any of the Class R Certificates by the Owner is or will be to impede the assessment or collection of any tax; in making this representation, the Owner warrants that the Owner is familiar with (i) Treasury Regulation Section 1.860E-1 (c) and recent amendments thereto, effective as of August 19, 2002, and (ii) the preamble describing the adoption of the amendments to such regulation, which is attached hereto as Exhibit 1.

11. That the Owner has no present knowledge or expectation that it will be unable to pay any United States taxes owed by it so long as any of the Certificates remain outstanding. In this regard, the Owner hereby represents to and for the benefit of the person from whom it acquired the Class R Certificates that the Owner intends to pay taxes associated

with holding such Class R Certificates as they become due, fully understanding that it may incur tax liabilities in excess of any cash flows generated by the Class R Certificates.

12. That the Owner has no present knowledge or expectation that it will become insolvent or subject to a bankruptcy proceeding for so long as any of the Class R Certificates remain outstanding.

13. The Owner is a citizen or resident of the United States, a corporation, partnership or other entity created or organized in, or under the laws of, the United States or any political subdivision thereof, or an estate or trust whose income from sources without the United States is includable in gross income for United States federal income tax purposes regardless of its connection with the conduct of a trade or business within the United States.

14. The Owner hereby agrees that it will not cause income from the Class R Certificates to be attributable to a foreign permanent establishment or fixed base (within the meaning of an applicable income tax treaty) of the Owner or another United States taxpayer.

15. (a) The Purchaser hereby certifies, represents and warrants to, and covenants with the Company and the Trustee that the following statements in (1) or (2) are accurate:

(1) The Certificates (i) are not being acquired by, and will not be transferred to, any employee benefit plan within the meaning of section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or other retirement arrangement, including individual retirement accounts and annuities, Keogh plans and bank collective investment funds and insurance company general or separate accounts in which such plans, accounts or arrangements are invested, that is subject to Section 406 of ERISA or Section 4975 of the Internal Revenue Code of 1986 (the “Code”) (any of the foregoing, a “Plan”), (ii) are not being acquired with “plan assets” of a Plan within the meaning of the Department of Labor (“DOL”) regulation, 29 C.F.R. ? 2510.3-101 or otherwise under ERISA, and (iii) will not be transferred to any entity that is deemed to be investing plan assets within the meaning of the DOL regulation, 29 C.F.R. ? 2510.3-101 or otherwise under ERISA;

(2) The purchase of Certificates is permissible under applicable law, will not constitute or result in any prohibited transaction under ERISA or Section 4975 of the Code, will not subject the Company or the Trustee to any obligation in addition to those undertaken in the Pooling and Servicing Agreement and, with respect to each source of funds (“Source”) being used by the Purchaser to acquire the Certificates, each of the following statements is accurate: (a) the Purchaser is an insurance company; (b) the Source is assets of the Purchaser’s “general account;” (c) the conditions set forth in Prohibited Transaction Class Exemption (“PTCE”) 95-60 issued by the DOL have been satisfied and the purchase, holding and transfer of Certificates by or on behalf of the Purchaser are exempt under PTCE 95-60; and (d) the amount of reserves and liabilities for such general account contracts held by or on behalf of any Plan does not exceed 10% of the total reserves and liabilities of such general account plus surplus as of the date hereof (for purposes of this clause, all Plans maintained by the same employer (or affiliate thereof) or employee organization are deemed to be a single Plan) in connection with its purchase and holding of such Certificates; or

(b) The Owner will provide the Trustee and the Company with an opinion of counsel acceptable to and in form and substance satisfactory to the Trustee and the Company to the effect that the purchase of Certificates is permissible under applicable law, will not constitute or result in any non-exempt prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Trustee or the Company to any obligation or liability (including obligations or liabilities under ERISA or Section 4975 of the Code) in addition to those undertaken in the Pooling and Servicing Agreement.

In addition, the Owner hereby certifies, represents and warrants to, and covenants with, the Company and the Trustee that the Owner will not transfer such Certificates to any Plan or person unless either such Plan or person meets the requirements set forth in either (a) or (b) above.

Capitalized terms used but not defined herein shall have the meanings assigned in the Pooling and Servicing Agreement.

Further, in determining such aggregate amount, the Buyer may have included securities owned by subsidiaries of the Buyer, but only if such subsidiaries are consolidated with the Buyer in its financial statements prepared in accordance with generally accepted accounting principles and if the investments of such subsidiaries are managed under the Buyer’s direction. However, such securities were not included if the Buyer is a majority-owned, consolidated subsidiary of another enterprise and the Buyer is not itself a reporting company under the Securities Exchange Act of 1934.

The Buyer acknowledges that it is familiar with Rule 144A and understands that the seller to it and other parties related to the

If the answer to the foregoing question is “no”, the Buyer agrees that, in connection with any purchase of securities sold to the Buyer for the account of a third party (including any separate account) in reliance on Rule 144A, the Buyer will only purchase for the account of a third party that at the time is a “qualified institutional buyer” within the meaning of Rule 144A. In addition, the Buyer agrees that the Buyer will not purchase securities for a third party unless the Buyer has obtained a current representation letter from such third party or taken other appropriate steps contemplated by Rule 144A to conclude that such third party independently meets the definition of “qualified institutional buyer” set forth in Rule 144A.

The Buyer will notify each of the parties to which this certification is made of any changes in the information and conclusions herein. Until such notice is given, the Buyer’s purchase of Rule 144A Securities will constitute a reaffirmation of this certification as of the date of such purchase.

Section 2.2. Recordation of Assignments. If any Mortgage File includes one or more assignments of Mortgage to the Trustee in a state which is specifically excluded from the Opinion of Counsel delivered by the Seller to the Trustee (with a copy to the Custodian) pursuant to the provisions of Section 2.01 of the Pooling and Servicing Agreement, each such assignment shall be delivered by the Custodian to the Company for the purpose of recording it in the appropriate public office for real property records, and the Company, at no expense to the Custodian, shall promptly cause to be recorded in the appropriate public office for real property records each such assignment of Mortgage and, upon receipt thereof from such public office, shall return each such assignment of Mortgage to the Custodian.

Section 2.3	Review of Mortgage Files.

(1) On or prior to the Closing Date, in accordance with Section 2.02 of the Pooling and Servicing Agreement, the Custodian shall deliver to the Trustee an Initial Certification in the form annexed hereto as Exhibit One evidencing receipt (subject to any exceptions noted therein) of a Mortgage File for each of the Mortgage Loans listed on the Schedule attached hereto (the A Mortgage Loan Schedule@).

Upon discovery by the Custodian of a breach of any representation or warranty made by the Company as set forth in the Pooling and Servicing Agreement with respect to a Mortgage Loan relating to a Mortgage File, the Custodian shall give prompt written notice to the Company, the Servicer and the Trustee.

Section 2.5. Custodian to Cooperate: Release of Mortgage Files. Upon receipt of written notice from the Trustee that the Mortgage Loan Seller has repurchased a Mortgage Loan pursuant to Article II of the Pooling and Servicing Agreement, and that the purchase price therefore has been deposited in the Custodial Account or the Distribution Account, then the Custodian agrees to promptly release to the Mortgage Loan Seller the related Mortgage File.

Upon the Custodian=s receipt of a request for release (a A Request for Release@) substantially in the form of Exhibit D to the Pooling and Servicing Agreement signed by a Servicing Officer of the Servicer stating that it has received payment in full of a Mortgage Loan or that payment in full will be escrowed in a manner customary for such purposes, the Custodian agrees promptly to release to the Servicer the related Mortgage File. The Company shall deliver to the Custodian and the Custodian agrees to accept the Mortgage Note and other documents constituting the Mortgage File with respect to any Substitute Mortgage Loan.

Upon receipt of the foregoing, the Custodian shall deliver the Mortgage File to the related Servicer. The Servicer shall cause each Mortgage File or any document therein so released to be returned to the Custodian when the need therefore by the related Servicer no longer exists, unless (i) the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Custodial Account or the Distribution Account or (ii) the Mortgage File or such document has been delivered to an attorney, or to a public trustee or other public official as required by law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially, and the Servicer has delivered to the Custodian a certificate of a Servicing Officer certifying as to the name and address of the Person to which such Mortgage File or such document was delivered and the purpose or purposes of such delivery.

At any time that the Servicer is required to deliver to the Custodian a Request for Release, the Servicer shall deliver two copies of the Request for Release if delivered in hard copy or the Servicer may furnish such Request for Release electronically to the Custodian, in which event the Servicing Officer transmitting the same shall be deemed to have signed the Request for Release. In connection with any Request for Release of a Mortgage File because of a

-3-

repurchase of a Mortgage Loan, such Request for Release shall be accompanied by an assignment of mortgage, without recourse, representation or warranty from the Trustee to the Mortgage Loan Seller and the related Mortgage Note shall be endorsed without recourse, representation or warranty by the Trustee (unless such Mortgage Note was a MERS Loan and not endorsed to the Trustee) and be returned to the Mortgage Loan Seller. In connection with any Request for Release of a Mortgage File because of the payment in full of a Mortgage Loan, such Request for Release shall be accompanied by a certificate of satisfaction or other similar instrument to be executed by or on behalf of the Trustee and returned to the related Servicer.

Section 2.6. Assumption Agreements.

-4-

that such cost or expense is indemnified by the Company or the Trust pursuant to the Pooling and Servicing Agreement.

Section 3.5. Custodian May Resign Trustee May Remove Custodian. The Custodian may resign from the obligations and duties hereby imposed upon it as such obligations and duties relate to its acting as Custodian of the Mortgage Loans.

If the Trustee shall not have taken custody of the Mortgage Files and no successor Custodian shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Custodian may petition any court of competent jurisdiction for the appointment of a successor Custodian.

The Trustee may remove the Custodian at any time with the consent of the Servicer.

Any successor Custodian shall be a depository institution subject to supervision or examination by federal or state authority, shall be able to satisfy the other requirements contained in Section 3.7 and shall be unaffiliated with the Servicer or the Company.

Any resignation or removal of the Custodian and appointment of a successor Custodian pursuant to any of the provisions of this Section 3.5 shall become effective upon acceptance of appointment by the successor Custodian. The Trustee shall give prompt notice to the Company and the Servicer of the appointment of any successor Custodian. No successor Custodian shall be appointed by the Trustee without the prior approval of the Company and the Servicer.

(i) The Purchaser will be entitled to all scheduled payments of principal and interest on the Mortgage Loans due after the Cut-off Date (regardless of when actually collected) and all payments thereon, other than scheduled principal and interest, received after the Cut-off Date. The Mortgage Loan Seller will be entitled to all scheduled payments of principal and interest on the Mortgage Loans due on or before the Cut-off Date (including payments collected after the Cut-off Date) and all payments thereon, other than scheduled principal and interest, received on or before the Cut-off Date. Such principal amounts and any interest thereon belonging to the Mortgage Loan Seller as described above will not be included in the aggregate outstanding principal balance of the Mortgage Loans as of the Cut-off Date as set forth on the Final Mortgage Loan Schedule.

(ii) Pursuant to various conveyance documents to be executed on the Closing Date and pursuant to the Pooling and Servicing Agreement, the Purchaser will assign on the Closing Date all of its right, title and interest in and to the Mortgage Loans to the Trustee for the benefit of the Certificateholders. In connection with the transfer and assignment of the Mortgage Loans, the Mortgage Loan Seller has delivered or will deliver or cause to be delivered to the Trustee by the Closing Date or such later date as is agreed to by the Purchaser and the Mortgage Loan Seller (each of the Closing Date and such later date is referred to as a "Mortgage File Delivery Date"), the items of each Mortgage File, provided, however, that in lieu of the foregoing, the Mortgage Loan Seller may deliver the following documents, under the circumstances set forth below: (x) 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 Mortgage Loan Seller in time to permit their delivery as specified above, the Mortgage Loan Seller may deliver a true copy thereof with a certification by the Mortgage Loan Seller, 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" (y) in lieu of the Security Instrument, assignments to the Trustee or intervening assignments thereof, if the applicable jurisdiction retains the originals of such documents (as evidenced by a certification from the Mortgage Loan

Seller to such effect) the Mortgage Loan Seller 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 (z) in lieu of the Mortgage Notes relating to the Mortgage Loans, each identified in the list delivered by the Purchaser to the Trustee on the Closing Date and attached hereto as Exhibit 5, the Mortgage Loan Seller may deliver lost note affidavits and indemnities of the Mortgage Loan Seller; 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, the Mortgage Loan Seller, in lieu of delivering the above documents, may deliver to the Trustee a certification by the Mortgage Loan Seller or the Servicer to such effect. The Mortgage Loan Seller shall deliver such original documents (including any original documents as to which certified copies had previously been delivered) or such certified copies to the Trustee promptly after they are received. The Mortgage Loan Seller shall cause the Mortgage and intervening assignments, if any, and the assignment of the Security Instrument to be recorded not later than 180 days after the Closing Date, unless such assignment is not required to be recorded under the terms set forth in Section 6(i) hereof.

(iii) The Mortgage Loan Seller and the Purchaser acknowledge hereunder that all of the Mortgage Loans and the related servicing will ultimately be assigned to Wells Fargo Bank, National Association, as Trustee for the benefit of the Certificateholders, on the date hereof.

SECTION 5. Examination of Mortgage Files.

(i) On or before the Mortgage File Delivery Date, the Mortgage Loan Seller will have made the Mortgage Files available to the Purchaser or its agent for examination which may be at the offices of the Trustee or the Mortgage Loan Seller and/or the Mortgage Loan Seller's custodian. The fact that the Purchaser or its agent has conducted or has failed to conduct any partial or complete examination of the Mortgage Files shall not affect the Purchaser's rights to demand cure, repurchase, substitution or other relief as provided in this Agreement. In furtherance of the foregoing, the Mortgage Loan Seller shall make the Mortgage Files available to the Purchaser or its agent from time to time so as to permit the Purchaser to confirm the Mortgage Loan Seller's compliance with the delivery and recordation requirements of this Agreement and the Pooling and Servicing Agreement. In addition, upon request of the Purchaser, the Mortgage Loan Seller agrees to provide to the Purchaser, Bear Stearns and to any investors or prospective investors in the Certificates information regarding the Mortgage Loans and their servicing, to make the Mortgage Files available to the Purchaser, Bear Stearns and to such investors or prospective investors (which may be at the offices of the Mortgage Loan Seller and/or the Mortgage Loan Seller's custodian) and to make available personnel knowledgeable about the Mortgage Loans for discussions with the Purchaser, Bear Stearns and such investors or prospective investors, upon reasonable request during regular business hours, sufficient to permit the Purchaser, Bear Stearns and such investors or potential investors to conduct such due diligence as any such party reasonably believes is appropriate.

(ii) Pursuant to the Pooling and Servicing Agreement, on the Closing Date the Trustee, for the benefit of the Certificateholders, will review or cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will execute and deliver or cause the Custodian to execute and deliver to the Mortgage Loan Seller an initial certification in the form attached as Exhibit One to the Custodial Agreement.

(iii) Pursuant to the Pooling and Servicing Agreement, within 90 days of the Closing Date, the Trustee will review or shall cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will execute and deliver, or cause to be executed and delivered, to the Mortgage Loan Seller and the Servicer an interim certification substantially in the form of Exhibit Two to the Custodial Agreement.

(iv) Pursuant to the Pooling and Servicing Agreement, within 180 days of the Closing Date (or, with respect to any Substitute Mortgage Loan, within five Business Days after the receipt by the Trustee or Custodian thereof) the Trustee will review or cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will deliver to the Mortgage Loan Seller and the Servicer a final certification substantially in the form of Exhibit Three to the Custodial Agreement. If the Trustee is unable to deliver a final certification with respect to the items listed in Exhibit 1 due to any document that is missing, has not been executed, is unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in the Final Mortgage Loan Schedule (a "Material Defect"), the Trustee or the Custodian, as its agent, shall promptly notify the Mortgage Loan Seller of such Material Defect. The Mortgage Loan Seller shall correct or cure any such Material 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 Mortgage Loan Seller does not correct or cure such Material Defect within such period and such defect materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan, the Mortgage Loan Seller will, in accordance with the terms of the Pooling and Servicing Agreement, within 90 days of the date of notice, provide the Trustee with a Substitute Mortgage Loan (if within two years of the Closing Date) or purchase the related Mortgage Loan at the applicable Purchase 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) of the Code, any such cure, repurchase or substitution 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 Mortgage Loan 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 Mortgage Loan Seller shall not be required to purchase such Mortgage Loan if the Mortgage Loan Seller delivers such original documents or certified copy promptly upon receipt, but in no event later than 360 days after the Closing Date. The foregoing repurchase obligation shall not apply in the event that the Mortgage Loan 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 Mortgage Loan Seller shall instead deliver a recording receipt of such recording office or, if such receipt is not available, a certificate of the Mortgage Loan Seller or the Servicing Officer 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 Mortgage Loan Seller within thirty days of its receipt of the original recorded document.

(v) At the time of any substitution, the Mortgage Loan Seller shall deliver or cause to be delivered the Substitute Mortgage Loan, the related Mortgage File and any other documents and payments required to be delivered in connection with a substitution pursuant to the Pooling and Servicing Agreement. At the time of any purchase or substitution, the Trustee shall (i) assign to the Mortgage Loan Seller and release or cause the Custodian to release the documents (including, but not limited to, the Mortgage, Mortgage Note and other contents of the

Mortgage File) in its possession or in the possession of the Custodian relating to the Deleted Mortgage Loan and (ii) execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the Mortgage Loan Seller title to such Deleted Mortgage Loan.

SECTION 6. Recordation of Assignments of Mortgage.

(i) The Mortgage Loan Seller shall, promptly after the Closing Date, cause each Mortgage and each assignment of Mortgage from the Mortgage Loan Seller to the Trustee, and all unrecorded intervening assignments, if any, delivered on or prior to the Closing Date, to be recorded in all recording offices in the jurisdictions where the related Mortgaged Properties are located; provided, however, the Mortgage Loan Seller need not cause to be recorded any assignment which relates to a Mortgage Loan if (a) such recordation is not required by the Rating Agencies or an Opinion of Counsel has been provided to the Trustee which states that the recordation of such assignment is not necessary to protect the Trustee's interest in the related Mortgage Loan or (b) MERS is identified on the Mortgage or a properly recorded assignment of the Mortgage, as the mortgagee of record solely as nominee for the Mortgage Loan Seller and its successors and assigns; provided, however, notwithstanding the delivery of any Opinion of Counsel, each assignment of Mortgage shall be submitted for recording by the Mortgage Loan Seller in the manner described above, at no expense to the Trust Fund or Trustee, 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 Mortgage Loan Seller and (iv) the occurrence of a servicing transfer as described in Section 8.02 of the Pooling and Servicing Agreement.

While each such Mortgage or assignment is being recorded, if necessary, the Mortgage Loan Seller shall leave or cause to be left with the Trustee a certified copy of such Mortgage or assignment. In the event that, within 180 days of the Closing Date, the Trustee has not been provided an Opinion of Counsel as described above or received evidence of recording with respect to each Mortgage Loan delivered to the Purchaser pursuant to the terms hereof or as set forth above, the failure to provide evidence of recording or such Opinion of Counsel (in the alternative, if required) shall be considered a Material Defect, and the provisions of Section 5(iii) and (iv) shall apply. All customary recording fees and reasonable expenses relating to the recordation of the assignments of Mortgage to the Trustee or the Opinion of Counsel, as the case may be, shall be borne by the Mortgage Loan Seller.

(ii) It is the express intent of the parties hereto that the conveyance of the Mortgage Loans by the Mortgage Loan Seller to the Purchaser, as contemplated by this Agreement be, and be treated as, a sale. It is, further, not the intention of the parties that such conveyance be deemed a pledge of the Mortgage Loans by the Mortgage Loan Seller to the Purchaser to secure a debt or other obligation of the Mortgage Loan Seller. However, in the event that, notwithstanding the intent of the parties, the Mortgage Loans are held by a court of competent jurisdiction to continue to be property of the Mortgage Loan Seller, then (a) this Agreement shall also be deemed to be a security agreement within the meaning of Article 9 of the applicable Uniform Commercial Code; (b) the transfer of the Mortgage Loans provided for herein shall be deemed to be a grant by the Mortgage Loan Seller to the Purchaser of a security

interest in all of the Mortgage Loan Seller's right, title and interest in and to the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, to the extent the Purchaser would otherwise be entitled to own such Mortgage Loans and proceeds pursuant to Section 4 hereof, including all amounts, other than investment earnings, from time to time held or invested in any accounts created pursuant to the Pooling and Servicing Agreement, whether in the form of cash, instruments, securities or other property; (c) the possession by the Purchaser or the Trustee of Mortgage Notes and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be deemed to be "possession by the secured party" for purposes of perfecting the security interest pursuant to Section 9-313 (or comparable provision) of the applicable Uniform Commercial Code; and (d) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Purchaser for the purpose of perfecting such security interest under applicable law. Any assignment of the interest of the Purchaser pursuant to any provision hereof or pursuant to the Pooling and Servicing Agreement shall also be deemed to be an assignment of any security interest created hereby. The Mortgage Loan Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be reasonably necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Pooling and Servicing Agreement.

SECTION 7. Representations and Warranties of Mortgage Loan Seller Concerning the Mortgage Loans. The Mortgage Loan Seller hereby represents and warrants to the Purchaser as of the Closing Date or such other date as may be specified below with respect to each Mortgage Loan being sold by it:

(ii) immediately prior to the transfer to the Purchaser, the Mortgage Loan Seller was the sole owner of beneficial title and holder of each Mortgage and Mortgage Note relating to the Mortgage Loans and is conveying the same to the Purchaser free and clear of any and all liens, claims, encumbrances, participation interests, equities, pledges, charges or security interests of any nature and the Mortgage Loan Seller has full right and authority to sell or assign the same pursuant to this Agreement;

(iii) each Mortgage Loan at the time it was made complied in all material respects with all applicable laws and regulations, including, without limitation, usury, equal credit opportunity, disclosure and recording laws and all predatory lending laws; and each Mortgage Loan has been serviced in all material respects in accordance with all applicable laws and regulations, including, without limitation, usury, equal credit opportunity, disclosure and recording laws and all predatory lending laws and the terms of the related Mortgage Note, the Mortgage and other loan documents;

(iv) there is no monetary default existing under any Mortgage or the related Mortgage Note and there is no material event which, with the passage of time or with notice and the expiration of any grace or cure period, would constitute a default, breach or event of acceleration; and neither the Mortgage Loan Seller, any of its affiliates nor any servicer of any related Mortgage Loan has taken any action to waive any default, breach or event of acceleration; no foreclosure action is threatened or has been commenced with respect to the Mortgage Loan;

(v) the terms of the Mortgage Note and the Mortgage have not been impaired, waived, altered or modified in any respect, except by written instruments, (i) if required by law in the jurisdiction where the Mortgaged Property is located, or (ii) to protect the interests of the Trustee on behalf of the Certificateholders;

(vi) no selection procedure reasonably believed by the Mortgage Loan Seller to be adverse to the interests of the Certificateholders was utilized in selecting the Mortgage Loans;

(vii) each Mortgage is a valid and enforceable first lien on the property securing the related Mortgage Note and each Mortgaged Property is owned by the Mortgagor in fee simple (except with respect to common areas in the case of condominiums, PUDs and de minimis PUDs) or by leasehold for a term longer than the term of the related Mortgage, subject only to (i) the lien of current real property taxes and assessments, (ii) covenants, conditions and restrictions, rights of way, easements and other matters of public record as of the date of recording of such Mortgage, such exceptions being acceptable to mortgage lending institutions generally or specifically reflected in the appraisal obtained in connection with the origination of the related Mortgage Loan or referred to in the lender's title insurance policy delivered to the originator of the related Mortgage Loan and (iii) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by such Mortgage;

as such loss, claim, damage, liability or action arises out of, or is based upon (i) any untrue statement of a material fact contained in the Mortgage Loan Seller's Information as identified in Exhibit 3, the omission to state in the Prospectus Supplement or Prospectus (or any amendment thereof or supplement thereto approved by the Mortgage Loan Seller and in which additional Mortgage Loan Seller's Information is identified), in reliance upon and in conformity with Mortgage Loan Seller's Information a material fact required to be stated therein or necessary to make the statements therein in light of the circumstances in which they were made, not misleading, (ii) any representation or warranty assigned or made by the Mortgage Loan Seller in Section 7 or Section 8 hereof being, or alleged to be, untrue or incorrect, or (iii) any failure by the Mortgage Loan Seller to perform its obligations under this Agreement; and the Mortgage Loan Seller shall reimburse the Purchaser and each other indemnified party for any legal and other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action.

In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent it may elect by written notice delivered to the indemnified party promptly (but, in any event, within 30 days) after receiving the aforesaid notice from such indemnified party, to

assume the defense thereof with counsel reasonably satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (a) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (b) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (c) such indemnified party or parties shall have reasonably concluded that there is a conflict of interest between itself or themselves and the indemnifying party in the conduct of the defense of any claim or that the interests of the indemnified party or parties are not substantially co-extensive with those of the indemnifying party (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties (provided, however, that the indemnifying party shall be liable only for the fees and expenses of one counsel in addition to one local counsel in the jurisdiction involved. Anything in this subsection to the contrary notwithstanding, an indemnifying party shall not be liable for any settlement or any claim or action effected without its written consent; provided, however, that such consent was not unreasonably withheld.

(iv) If the indemnification provided for in paragraphs (i) and (ii) of this Section 13 shall for any reason be unavailable to an indemnified party in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to in Section 13, then the indemnifying party shall in lieu of indemnifying the indemnified party contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative benefits received by the Mortgage Loan Seller on the one hand and the Purchaser on the other from the purchase and sale of the Mortgage Loans, the offering of the Certificates and the other transactions contemplated hereunder. No person found liable for a fraudulent misrepresentation shall be entitled to contribution from any person who is not also found liable for such fraudulent misrepresentation.

The Seller agrees to provide to the Purchaser as of the date hereof a preliminary listing of the Subsequent Mortgage Loans (the "Preliminary Subsequent Mortgage Loan Schedule") setting forth the information listed on Exhibit 2 to this Agreement with respect to each of the Subsequent Mortgage Loans being sold by the Seller.

The Final Subsequent Mortgage Loan Schedule shall be delivered to the Purchaser on the Subsequent Transfer Date, shall be attached to an amendment to this Agreement to be executed on the Subsequent Transfer Date by the parties hereto and shall be in form and substance mutually agreed to by the Seller and the Purchaser (the "Amendment"). If there are no changes to the Preliminary Subsequent Mortgage Loan Schedule, the Preliminary Subsequent Mortgage Loan Schedule shall be the Final Subsequent Mortgage Loan Schedule for all purposes hereof.

SECTION 4. Subsequent Mortgage Loan Transfer.

(a) The Purchaser will be entitled to all scheduled payments of principal and interest on the Subsequent Mortgage Loans due after the Subsequent Cut-off Date (regardless of when actually collected) and all payments thereon other than scheduled principal and interest on the Subsequent Mortgage Loans due on or before the Subsequent Cut-off Date and received after the Subsequent Cut-off Date. The Seller will be entitled to all scheduled payments of principal and interest on the Subsequent Mortgage Loans due on or before the Subsequent Cut-off Date (including payments collected after the Subsequent Cut-off Date) and all payments thereon other than scheduled principal and interest on the Subsequent Mortgage Loans due after the Subsequent Cut-off Date and received on or before the Subsequent Cut-off Date. Such principal amounts and any interest thereon belonging to the Seller as described above will not be included in the aggregate outstanding principal balance of the Subsequent Mortgage Loans as of the Subsequent Cut-off Date as set forth on the Final Subsequent Mortgage Loan Schedule.

(b) Pursuant to various conveyance documents to be executed on the Subsequent Transfer Date and pursuant to the Pooling and Servicing Agreement, the Purchaser will assign on the Subsequent Transfer Date all of its right, title and interest in and to the Subsequent Mortgage Loans to the Trustee for the benefit of the Certificateholders. In connection with the transfer and assignment of the Subsequent Mortgage Loans, the Seller has delivered or will deliver or cause to be delivered to the Trustee no later than three Business Days prior to the Subsequent Transfer Date or such later date as is agreed to by the Purchaser and the Seller (each of the Subsequent Transfer Date and such later date is referred to as a "Mortgage File Delivery Date"), the items of each Mortgage File, provided, however, that in lieu of the foregoing, the Seller may deliver the following documents, under the circumstances set forth below: (x) 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 Seller in time to permit their delivery as specified above, the Seller may deliver a true copy thereof with a certification by the Seller, 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;" (y) in lieu of the Security Instrument, assignments to the Trustee or intervening assignments thereof, if the applicable jurisdiction retains the originals of such documents or if the originals are lost (in each case, as evidenced by a certification from the Seller to such effect), the Seller 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 (z) in lieu of the Mortgage Notes relating to the Subsequent Mortgage Loans, each identified in the list delivered by the Purchaser to the Trustee on the Subsequent Transfer Date and attached hereto as Exhibit 3, the Seller may deliver lost note affidavits and indemnities of the Seller; and provided further, however, that in the case of Subsequent Mortgage Loans which have been prepaid in full after the Subsequent Cut-off Date and prior to the Subsequent Transfer Date, the Seller, in lieu of delivering the above documents, may deliver to the Trustee a certification by the Seller or the Servicer to such effect. The Seller shall deliver such original documents (including any original documents as to which certified copies had previously been delivered) or such certified copies to the Trustee promptly after they are received. The Seller shall cause the Security Instrument and intervening assignments, if any, and the assignment of the Mortgage to be recorded not later than 180 days after the Subsequent Transfer Date, unless such assignment is not required to be recorded under the terms set forth in Section 6(a) hereof.

(c) The Seller and the Purchaser acknowledge hereunder that all of the Subsequent Mortgage Loans and the related servicing will ultimately be assigned to Wells Fargo Bank, National Association, as Trustee for the benefit of the Certificateholders, on the date hereof.

SECTION 5. Examination of Mortgage Files.

(a) On or before the Mortgage File Delivery Date, the Seller will have made the Mortgage Files available to the Purchaser or its agent for examination, which may be at the offices of the Trustee or the Seller and/or the Seller's custodian. The fact that the Purchaser or its agent has conducted or has failed to conduct any partial or complete examination of the Mortgage Files shall not affect the Purchaser's rights to demand cure, repurchase, substitution or other relief as provided in this Agreement. In furtherance of the foregoing, the Seller shall make the Mortgage Files available to the Purchaser or its agent from time to time so as to permit the Purchaser to confirm the Seller's compliance with the delivery and recordation requirements of this Agreement and the Pooling and Servicing Agreement. In addition, upon request of the Purchaser, the Seller agrees to provide to the Purchaser, Bear Stearns and to any investors or prospective investors in the Certificates information regarding the Subsequent Mortgage Loans and their servicing, to make the Mortgage Files available to the Purchaser, Bear Stearns and to such investors or prospective investors (which may be at the offices of the Seller and/or the Seller's custodian) and to make available personnel knowledgeable about the Subsequent Mortgage Loans for discussions with the Purchaser, Bear Stearns and such investors or prospective investors, upon reasonable request during regular business hours, sufficient to permit the Purchaser, Bear Stearns and such investors or potential investors to conduct such due diligence as any such party reasonably believes is appropriate.

(b) Pursuant to the Pooling and Servicing Agreement, on or prior to the Subsequent Transfer Date, the Custodian shall acknowledge with respect to each Subsequent

Mortgage Loan, by an Initial Certification substantially in the form of Exhibit One to the Custodial Agreement, receipt of the related 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.

(c) Pursuant to the Pooling and Servicing Agreement, no later than 90 days after the Subsequent Transfer Date, the Trustee, for the benefit of the Certificateholders, will review or cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will execute and deliver, or cause to be executed and delivered, to the Seller a certification in the form attached as Exhibit Two to the Custodial Agreement.

(d) Pursuant to the Pooling and Servicing Agreement, the Trustee will review or cause the Custodian to review the Mortgage Files within 180 days of the Subsequent Transfer Date and will execute and deliver, or cause to be executed and delivered, to the Seller and the Servicer a final certification substantially in the form of Exhibit Three to the Custodial Agreement. If the Trustee, or the Custodian, as its agent, is unable to deliver a final certification with respect to the items listed in Exhibit 2 due to any document that is missing, has not been executed, is unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Subsequent Mortgage Loans identified in the Final Subsequent Mortgage Loan Schedule or appears to be defective on its face (a "Material Defect"), the Trustee, or the Custodian, as its agent, shall promptly notify the Seller of such Material Defect. The Seller shall correct or cure any such Material 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 does not correct or cure such Material Defect within such period and such defect materially and adversely affects the interests of the Certificateholders in the related Subsequent Mortgage Loan, the Seller will, in accordance with the terms of the Pooling and Servicing Agreement, within 90 days of the date of notice, provide the Trustee with a Substitute Mortgage Loan (if within two years of the Closing Date) or purchase the related Subsequent Mortgage Loan at the applicable Purchase Price; provided that, if such defect would cause the Subsequent Mortgage Loan to be other than a "qualified mortgage" as defined in Section 860G(a)(3) of the Code, any such cure, repurchase or substitution 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 thereto, 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 Subsequent 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 Subsequent Transfer Date. 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 of the Seller or Servicing Officer 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.

(e) At the time of any substitution, the Seller shall deliver or cause to be delivered the Substitute Mortgage Loan, the related Mortgage File and any other documents and

payments required to be delivered in connection with a substitution pursuant to the Pooling and Servicing Agreement. At the time of any purchase or substitution, the Trustee shall (i) assign to the Seller and release or cause the Custodian to release the documents (including, but not limited to, the Mortgage, Mortgage Note and other contents of the Mortgage File) in its possession or in the possession of the Custodian relating to the Deleted Subsequent Mortgage Loan and (ii) execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the Seller title to such Deleted Subsequent Mortgage Loan.

SECTION 6. Recordation of Assignments of Mortgage.

(a) The Seller will, promptly after the Subsequent Transfer Date, cause each Mortgage and each assignment of Mortgage from the Seller to the Trustee, and all unrecorded intervening assignments, if any, delivered on or prior to the Subsequent Transfer Date, to be recorded in all recording offices in the jurisdictions where the related Mortgaged Properties are located; provided, however, the Seller need not cause to be recorded any assignment which relates to a Subsequent Mortgage Loan if (a) such recordation is not required by the Rating Agencies or an Opinion of Counsel has been provided to the Trustee which states that the recordation of such assignment is not necessary to protect the Trustee's interest in the related Subsequent Mortgage Loan or (b) MERS is identified on the Mortgage or a properly recorded assignment of the Mortgage as mortgagee of record solely as nominee for Seller and its successors and assigns; provided, however, notwithstanding the delivery of any Opinion of Counsel, each assignment of Mortgage shall be submitted for recording by the Seller in the manner described above, at no expense to the Trust Fund or Trustee, 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 of the Pooling and Servicing Agreement.

While each such Mortgage or assignment is being recorded, if necessary, the Seller shall leave or cause to be left with the Trustee a certified copy of such Mortgage or assignment. In the event that, within 180 days of the Subsequent Transfer Date, the Trustee has not been provided an Opinion of Counsel as described above or received evidence of recording with respect to each Subsequent Mortgage Loan delivered to the Purchaser pursuant to the terms hereof or as set forth above, the failure to provide evidence of recording or such Opinion of Counsel shall be considered a Material Defect, and the provisions of Section 5(c) and (d) shall apply. All customary recording fees and reasonable expenses relating to the recordation of the assignments of Mortgages to the Trustee or the Opinion of Counsel, as the case may be, shall be borne by the Seller.

(b) It is the express intent of the parties hereto that the conveyance of the Subsequent Mortgage Loans by the Seller to the Purchaser, as contemplated by this Agreement be, and be treated as, a sale. It is, further, not the intention of the parties that such conveyance be deemed a pledge of the Subsequent Mortgage Loans by the Seller to the Purchaser to secure a debt or other obligation of the Seller. However, in the event that, notwithstanding the intent of the parties, the Subsequent Mortgage Loans are held by a court of competent jurisdiction to continue to be property of the Seller, then (i) this Agreement shall also be deemed to be a

security agreement within the meaning of Article 9 of the applicable Uniform Commercial Code; (ii) the transfer of the Subsequent Mortgage Loans provided for herein shall be deemed to be a grant by the Seller to the Purchaser of a security interest in all of the Seller's right, title and interest in and to the Subsequent Mortgage Loans and all amounts payable to the holders of the Subsequent Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, to the extent the Purchaser would otherwise be entitled to own such Subsequent Mortgage Loans and proceeds pursuant to Section 4 hereof, including all amounts, other than investment earnings, from time to time held or invested in any accounts created pursuant to the Pooling and Servicing Agreement, whether in the form of cash, instruments, securities or other property; (iii) the possession by the Purchaser or the Trustee of Mortgage Notes and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be deemed to be "possession by the secured party" for purposes of perfecting the security interest pursuant to Section 9-313 (or comparable provision) of the applicable Uniform Commercial Code; and (iv) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Purchaser for the purpose of perfecting such security interest under applicable law. Any assignment of the interest of the Purchaser pursuant to any provision hereof or pursuant to the Pooling and Servicing Agreement shall also be deemed to be an assignment of any security interest created hereby. The Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be reasonably necessary to ensure that, if this Agreement were deemed to create a security interest in the Subsequent Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Pooling and Servicing Agreement.

SECTION 7. Representations and Warranties of Seller Concerning the Subsequent Mortgage Loans. The Seller hereby represents and warrants to the Purchaser as of the Subsequent Transfer Date, or such other date as may be specified below with respect to each Subsequent Mortgage Loan being sold by it, that:

(iv) there is no monetary default existing under any Mortgage or the related Mortgage Note and there is no material event which, with the passage of time or with notice and the expiration of any grace or cure period, would constitute a default, breach or event of acceleration; and neither the Seller, any of its affiliates nor any servicer of any related Subsequent Mortgage Loan has taken any action to waive any default, breach or event of acceleration; and no foreclosure action is threatened or has been commenced with respect to the Subsequent Mortgage Loan;

(v) the terms of the Mortgage Note and the Mortgage have not been impaired, waived, altered or modified in any respect, except by written instruments, (x) if required by law in the jurisdiction where the Mortgaged Property is located, or (y) to protect the interests of the Trustee on behalf of the Certificateholders;

(vi) no selection procedure reasonably believed by the Seller to be adverse to the interests of the Certificateholders was utilized in selecting the Subsequent Mortgage Loans;

(vii) each Mortgage is a valid and enforceable first lien on the property securing the related Mortgage Note and each Mortgaged Property is owned by the Mortgagor in fee simple (except with respect to common areas in the case of condominiums, PUDs and de minimis PUDs) or by leasehold for a term longer than the term of the related Mortgage, subject only to (x) the lien of current real property taxes and assessments, (y) covenants, conditions and restrictions, rights of way, easements and other matters of public record as of the date of recording of such Mortgage, such exceptions being acceptable to mortgage lending institutions generally or specifically reflected in the appraisal obtained in connection with the origination of the related Subsequent Mortgage Loan or referred to in the lender's title insurance policy delivered to the originator of the related Subsequent Mortgage Loan and (z) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by such Mortgage;

The Seller is the sole insured under such lender's title insurance policy, and such policy, binder or assurance is valid and remains in full force and effect, and each such policy, binder or assurance shall contain all applicable endorsements including a negative amortization endorsement, if applicable;

The foregoing indemnity agreement is in addition to any liability which the Seller otherwise may have to the Purchaser or any other such indemnified party.

(b) The Purchaser shall indemnify and hold harmless the Seller and its respective directors, officers and controlling persons (as defined in Section 15 of the Securities Act) from and against any loss, claim, damage or liability or action in respect thereof, to which they or any of them may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon (i) any representation or warranty made by the Purchaser in Section 9 hereof being, or alleged to be, untrue or incorrect, or (ii) any failure by the Purchaser to perform its obligations under this Agreement; and the Purchaser shall reimburse the Seller, and each other indemnified party for any legal and other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend any such loss, claim, damage, liability or action.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each

party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve such indemnified party from any liability which it may have under this Section 13 except to the extent that it has been prejudiced in any material respect by such failure or from any liability which it may have otherwise). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent it may elect by written notice delivered to the indemnified party promptly (but, in any event, within 30 days) after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have reasonably concluded that there is a conflict of interest between itself or themselves and the indemnifying party in the conduct of the defense of any claim or that the interests of the indemnified party or parties are not substantially co-extensive with those of the indemnifying party (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties (provided, however, that the indemnifying party shall be liable only for the fees and expenses of one counsel in addition to one local counsel in the jurisdiction involved. Anything in this subsection to the contrary notwithstanding, an indemnifying party shall not be liable for any settlement or any claim or action effected without its written consent; provided, however, that such consent was not unreasonably withheld.

(d) If the indemnification provided for in paragraphs (a) and (b) of this Section 13 shall for any reason be unavailable to an indemnified party in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to in this Section 13, then the indemnifying party shall, in lieu of indemnifying the indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative benefits received by the Seller on the one hand and the Purchaser on the other from the purchase and sale of the Subsequent Mortgage Loans, the offering of the Certificates and the other transactions contemplated hereunder. No person found liable for a fraudulent misrepresentation shall be entitled to contribution from any person who is not also found liable for such fraudulent misrepresentation.

(e) The parties hereto agree that reliance by an indemnified party on any publicly available information or any information or directions furnished by an indemnifying party shall not constitute negligence, bad faith or willful misconduct by such indemnified party.

and notices to the Purchaser shall be directed to Structured Asset Mortgage Investments II Inc., 383 Madison Avenue, New York, New York 10179 (Telecopy: (212-272-7206)), Attention: Baron Silverstein; or to any other address as may hereafter be furnished by one party to the other party by like notice. Any such demand, notice or communication hereunder shall be deemed to have been received on the date received at the premises of the addressee (as evidenced, in the case of registered or certified mail, by the date noted on the return receipt) provided that it is received on a Business Day during normal business hours and, if received after normal business hours, then it shall be deemed to be received on the next Business Day.

SECTION 15. Transfer of Subsequent Mortgage Loans. The Purchaser retains the right to assign the Subsequent Mortgage Loans and any or all of its interest under this Agreement to the Trustee without the consent of the Seller, and, upon such assignment, the Trustee shall succeed to the applicable rights and obligations of the Purchaser hereunder; provided, however, the Purchaser shall remain entitled to the benefits set forth in Sections 11, 13 and 17 hereto and as provided in Section 2(a). Notwithstanding the foregoing, the sole and exclusive right and remedy of the Trustee with respect to a breach of representation or warranty of the Seller shall be the cure, purchase or substitution obligations of the Seller contained in Sections 5 and 7 hereof.

This Agreement may be terminated (a) by the mutual consent of the parties hereto prior to the Subsequent Transfer Date, (b) by the Purchaser, if the conditions to the Purchaser's obligation to close set forth under Section 10(a) hereof are not fulfilled as and when required to be fulfilled or (c) by the Seller, if the conditions to the Seller's obligation to close set forth under Section 10(b) hereof are not fulfilled as and when required to be fulfilled.

Any person into which the Seller may be merged or consolidated (or any person resulting from any merger or consolidation involving the Seller), any person resulting from a change in form of the Seller or any person succeeding to the business of the Seller, shall be considered the "successor" of the Seller hereunder and shall be considered a party hereto without the execution or filing of any paper or any further act or consent on the part of any party hereto. Except as provided in the two preceding sentences and in Section 15 hereto, this Agreement cannot be assigned, pledged or hypothecated by either party hereto without the written consent of the other parties to this Agreement and any such assignment or purported assignment shall be deemed null and void.

SECTION 24. The Seller and the Purchaser. The Seller and the Purchaser will keep in full effect all rights as are necessary to perform their respective obligations under this Agreement.
