The Mortgage Loans will have an Outstanding Principal Balance as of the Cut-off Date of $813,147,730.96.

In consideration of the mutual agreements herein contained, the Depositor, the Servicer, the Seller, the Company and the Trustee agree as follows:

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 and 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) 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 Mortgage Loans, to the extent not covered by Compensating Interest Payments paid by the Servicer, (b) interest shortfalls on the Mortgage Loans resulting from the application of the Relief Act or similar state law, (c) after the 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 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, to the extent not covered by Compensating Interest Payment paid by the Servicer, (b) interest shortfalls on the Mortgage Loans resulting from the application of the Relief Act or similar state law, (c) 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 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 Class X-1 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 X Certificates and (ii) a 360-day year and the actual number of days elapsed in the Interest Accrual Period for the Class A, 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 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 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.

Senior Percentage

In addition, no reduction of the Senior Prepayment Percentage shall occur on any Distribution Date unless, as of the last day of the month preceding such Distribution Date, (A) the aggregate Scheduled 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 50%; and (B) cumulative Realized Losses on the Mortgage Loans do not exceed (a) 30% of the Original Subordinate Principal Balance if such Distribution Date occurs between and including June 2015 and May 2016, (b) 35% of the Original Subordinate Principal Balance if such Distribution Date occurs between and including June 2016 and May 2017, (c) 40% of the Original Subordinate Principal Balance if such Distribution Date occurs between and including June 2017 and May 2018, (d) 45% of the Original Subordinate Principal Balance if such Distribution Date occurs between and including June 2018 and May 2019, and (e) 50% of the Original Subordinate Principal Balance if such Distribution Date occurs during or after June 2019.

In addition, if on any Distribution Date the Subordinate Percentage is equal to or greater than two times the initial Subordinate Percentage, and (a) the aggregate Scheduled Principal Balance of the Mortgage Loans delinquent 60 days or more (including for this purpose any such Mortgage Loans in foreclosure and such 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 aggregate Current Principal Amount of the Subordinate Certificates does not exceed 50% and (b)(i) on or prior to the Distribution Date in May 2008, cumulative Realized Losses on the Mortgage Loans as of the end of the related Prepayment Period do not exceed 20% of the Original Subordinate Principal Balance and (ii) after the Distribution Date in May 2008 cumulative Realized Losses on the Mortgage Loans as of the end of the related Prepayment Period do not exceed 30% of the Original Subordinate Principal Balance, then, the Senior Prepayment Percentage for such Distribution Date will equal the Senior Percentage; provided, however, if on such Distribution Date the Subordinate Percentage is equal to or greater than two times the initial Subordinate Percentage on or prior to the Distribution Date occurring in May 2008 and the above delinquency and loss tests are met, then the Senior Prepayment Percentage for such Distribution Date will equal the Senior Percentage plus 50% of the related Subordinate Percentage.

Notwithstanding the foregoing, if on any Distribution Date the percentage, the numerator of which is the aggregate Current Principal Amount of the Senior Certificates immediately preceding such Distribution Date, and the denominator of which is the Scheduled Principal Balance of the Mortgage Loans as of the beginning of the related Due Period, exceeds such percentage as of the Cut-Off Date, the Senior Prepayment Percentage for the Senior Certificates will equal 100%.

ARTICLE II

Conveyance of Mortgage Loans;

Original Issuance of Certificates

Section 2.01 Conveyance of Mortgage Loans to Trustee . (a) The Depositor concurrently with the execution and delivery of this Agreement, sells, transfers and assigns to the Trust without recourse all its right, title and interest in and to (i) the Mortgage Loans identified in the Mortgage Loan Schedule, including all interest due and principal received with respect to the Mortgage Loans after the Cut-off Date, 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 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, 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. The Depositor shall deliver such original documents (including any original documents as to which certified copies had previously been delivered) to the Trustee or the Custodian, as its agent, promptly after they are received. The Depositor shall cause the Seller, at its expense, to cause each assignment of the Security Instrument to the Trustee to be recorded not later than 180 days after the Closing Date, unless (a) such recordation is not required by the Rating Agencies or an Opinion of Counsel addressed to the Trustee has been provided to the Trustee (with a copy to the Custodian) which states that recordation of such Security Instrument is not required to protect the interests of the Certificateholders in the related Mortgage Loans or (b) MERS is identified on the Mortgage or on a properly recorded assignment of the Mortgage as the mortgagee of record solely as nominee for the Seller and its successor and assigns; provided, however, that each assignment shall be submitted for recording by the Seller in the manner described above, at no expense to the Trust or the Trustee or the Custodian, as its agent, upon the earliest to occur of: (i) reasonable direction by the Holders of Certificates evidencing Fractional Undivided Interests

aggregating not less than 25% of the Trust, (ii) the occurrence of an Event of Default, (iii) the occurrence of a bankruptcy, insolvency or foreclosure relating to the Seller and (iv) the occurrence of a servicing transfer as described in Section 8.02 hereof. Notwithstanding the foregoing, if the Seller fails to pay the cost of recording the assignments, such expense will be paid by the Trustee and the Trustee shall be reimbursed for such expenses by the Trust in accordance with Section 9.05.

Section 2.02 Acceptance of Mortgage Loans by Trustee . (a) The Trustee (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 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 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, 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, 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, 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 1.860(g-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. 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 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, 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, 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 1.860(g-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. 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 . (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. 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 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 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 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 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 or this Agreement, as applicable; provided , however , that substitution pursuant to the 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 1.860(g-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 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 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 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 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:

(i) the Depositor (a) is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and (b) is qualified and in good standing as a foreign corporation to do business in each jurisdiction where such qualification is necessary, except where the failure so to qualify would not reasonably be expected to have a material adverse effect on the Depositor’s business as presently conducted or on the Depositor’s ability to enter into this Agreement and to consummate the transactions contemplated hereby;

(ii) the Depositor has full corporate power to own its property, to carry on its business as presently conducted and to enter into and perform its obligations under this Agreement;

(iii) the execution and delivery by the Depositor of this Agreement have been duly authorized by all necessary corporate action on the part of the Depositor; and neither the execution and delivery of this Agreement, nor the consummation of the transactions herein contemplated, nor compliance with the provisions hereof, will conflict with or result in a breach of, or constitute a default under, any of the provisions of any law, governmental rule, regulation, judgment, decree or order binding on the Depositor or its properties or the articles of incorporation or by-laws of the Depositor, except those conflicts, breaches or defaults which would not reasonably be expected to have a material adverse effect on the Depositor’s ability to enter into this Agreement and to consummate the transactions contemplated hereby;

(iv) the execution, delivery and performance by the Depositor of this Agreement and the consummation of the transactions contemplated hereby do not require the consent or approval of, the giving of notice to, the registration with, or the taking of any other action in respect of, any state, federal or other governmental authority or agency, except those consents, approvals, notices, registrations or other actions as have already been obtained, given or made;

(v) this Agreement has been duly executed and delivered by the Depositor and, assuming due authorization, execution and delivery by the other parties hereto, constitutes a valid and binding obligation of the Depositor enforceable against it in accordance with its terms (subject to applicable bankruptcy and insolvency laws and other similar laws affecting the enforcement of the rights of creditors generally);

(vi) there are no actions, suits or proceedings pending or, to the knowledge of the Depositor, threatened against the Depositor, before or by any court, administrative agency, arbitrator or governmental body (i) with respect to any of the transactions contemplated by this Agreement or (ii) with respect to any other matter which in the judgment of the Depositor will be determined adversely to the Depositor and will if determined adversely to the Depositor materially and adversely affect the Depositor’s ability to enter into this Agreement or perform its obligations under this Agreement; and the Depositor is not in default with respect to any order of any court, administrative agency, arbitrator or governmental body so as to materially and adversely affect the transactions contemplated by this Agreement; and

(vii) immediately prior to the transfer and assignment to the Trust, each Mortgage Note and each Mortgage were not subject to an assignment or pledge, and the Depositor had good and marketable title to and was the sole owner thereof and had full right to transfer and sell such Mortgage Loan to the Trustee free and clear of any encumbrance, equity, lien, pledge, charge, claim or security interest.

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-AR2 REMIC shall exist, the Trustee shall act in accordance herewith to assure continuing treatment of such 2005-AR2 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 or Section 2.04 of this Agreement, as applicable, accept any contribution to any 2005-AR2 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-AR2 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-AR2 REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon any 2005-AR2 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. ˆgpK8%

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 premium or penalty) 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 fiscal 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 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 and file each such document 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 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.

(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;

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 prepayment or late payment charges or assumption, tax service, statement account or payoff, substitution, satisfaction, release and other like fees and charges, need not be credited by the Servicer to the Distribution Account or the Custodial Account, as applicable. 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.

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.

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.

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.

(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;

(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;

(vii) to reimburse the Trustee or the Servicer for any Monthly Advance or advance, after a Realized Loss has been allocated with respect to the related Mortgage Loan if the Monthly Advance or advance 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);

(c) On each Distribution Date, the Trustee shall distribute the Available Funds to the extent on deposit in the Distribution Account to the Holders of the 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 MTA Trust 2005-AR2, Mortgage Pass-Through Certificates, Series 2005-AR2” (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 $1,100,000 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 A Certificates to the extent that Accrued Certificate Interest on the Class A Certificates is reduced by application of the Net Rate Cap on such initial Distribution Date. The Class A Reserve Fund will then be entitled to be replenished on each future Distribution Date from amounts otherwise payable as interest on the Class X-1 Certificates 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.

With respect to each month, such Report shall be received by the Trustee no later than the 10th calendar day of the month of the related Distribution Date (or June 14, 2005, in the case of the initial Report) a report in an Excel (or compatible) electronic format (that can be downloaded into a Sybase database), in such format as may be mutually agreed upon by both the Trustee and the Servicer, and in hard copy, which Report shall contain the following:

(ii) the amount of Servicing Compensation received by the Servicer during the prior Due Period;

(iii)

the aggregate Stated Principal Balance of the Mortgage Loans;

(iv) the number and aggregate outstanding principal balances of Mortgage Loans (a) delinquent (1) 30 to 59 days, (2) 60 to 89 days, (3) 90 days or more; (b) as to which foreclosure has commenced; and (c) as to which REO Property has been acquired; and

(v)	such other data as may reasonably be required by the Trustee in order to make distributions to the Certificateholders on such Distribution Date.

The Servicer shall also provide with each such Report a trial balance, sorted in the Trustee's assigned loan number order, and such other loan level information as described on Exhibits K and L , in electronic tape form.

The Servicer shall prepare and file any and all information statements or other filings required to be delivered to any governmental taxing authority or to the Trustee pursuant to any applicable law with respect to the Mortgage Loans and the transactions contemplated hereby. In addition, the Servicer shall provide the Trustee with such information concerning the Mortgage Loans as is necessary for the Trustee to prepare the Trust's income tax returns as the Trustee may reasonably request from time to time.

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 the REMIC I Residual Interest will have the following designations, initial balances and pass-through rates:
