(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 their respective Mortgage Loan Schedules, including all interest and principal due with respect to the Mortgage Loans after the Cut-off Date but excluding any payments of principal and interest due on or prior to the Cut-off Date; (ii) such assets as shall from time to time be credited or are required by the terms of this Agreement to be credited to the Master Servicer Collection Account, (iii) such assets relating to the Mortgage Loans as from time to time may be held by the Servicers in Protected Accounts, the Master Servicer in the Master Servicer Collection Account and the Paying Agent 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 Subsection 2.03(a), (vii) the rights with respect to the Servicing Agreements as assigned to the Trustee on behalf of the Certificateholders by the Assignment Agreements, (viii) such assets as shall from time to time be credited or are required by the terms of this Agreement to be credited to the Distribution Account and (ix) any proceeds of the foregoing. Although it is the intent of the parties to this Agreement that the conveyance of the Depositor’s right, title and interest in and to the Mortgage Loans and other assets in the Trust Fund pursuant to this Agreement shall constitute a purchase and sale and not a loan, in the event that such conveyance is deemed to be a loan, it is the intent of the parties to this Agreement that the Depositor shall be deemed to have granted to the Trustee a first priority perfected security interest in all of the Depositor’s right, title and interest in, to and under the Mortgage Loans and other assets in the Trust Fund, and that this Agreement shall constitute a security agreement under applicable law.

(b) In connection with the above transfer and assignment, the Depositor hereby delivers to the Custodian, as agent for the Trustee, 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 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 “U.S. 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 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 to the Custodian, as agent of the Trustee, 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; (y) in lieu of the Mortgage Notes relating to the Mortgage Loans identified on Exhibit 5 to the Mortgage Loan Purchase Agreement, the Depositor may deliver lost note affidavits from the Seller; and (z) the Depositor shall not be required to deliver intervening assignments or Mortgage Note endorsements between the related Underlying Seller and the Seller, 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 Master Servicer Collection 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,

notwithstanding the foregoing, each assignment shall be submitted for recording by the Seller in the manner described above, at no expense to the Trust or the Trustee or the Custodian, as its agent, upon the earliest to occur of: (i) reasonable direction by the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust, (ii) the occurrence of an Event of Default, (iii) the occurrence of a bankruptcy, insolvency or foreclosure relating to the Seller and (iv) the occurrence of a servicing transfer as described in Section 8.02 hereof. Notwithstanding the foregoing, if the Seller fails to pay the cost of recording the assignments, such expense will be paid by the Trustee and the Trustee shall be reimbursed for such expenses by the Trust in accordance with Section 9.05.

Section 2.02

Acceptance of Mortgage Loans by Trustee.

(a) The Trustee acknowledges the sale, transfer and assignment of the Trust Fund to it 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 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 related 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 related Mortgage Loan Schedule. In performing any such review, the Trustee or the Custodian, as its agent, may conclusively rely on the purported due execution and genuineness of any such document and on the purported genuineness of any signature thereon. If the Trustee or the Custodian, as its agent, finds any document constituting part of the Mortgage File has not been executed or received, or to be unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in Exhibit B, 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 shall enforce the Seller’s obligation under the Mortgage Loan Purchase Agreement, within 90 days from the Trustee’s or the Custodian’s notification, provide a Substitute Mortgage Loan (if within two years of the Closing

Date) or 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) of the Code, 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 subsections (b)(iv), (v) and (vii) of Section 2.01, the Trustee’s and Custodian’s obligations shall extend only to the documents actually delivered to the Custodian pursuant to such subsections). 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, within 90 days from the Trustee’s or Custodian’s notification, provide a Substitute Mortgage Loan (if within two years of the Closing Date) or 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) of the Code, any such cure, repurchase or substitution must occur within 90 days from the date such breach was discovered, provided, however, that if such defect relates solely to the inability of the Seller to deliver the original Security Instrument or intervening assignments thereof, or a certified copy, 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 Subsections 2.02(a) or (b) above, the Seller shall remit to the Master Servicer the Repurchase Price for deposit in the Master Servicer Collection Account and the Seller shall provide to the Master Servicer, Securities Administrator, the Paying Agent and the Trustee written notification detailing the components of the Repurchase Price to the Trustee, the Paying Agent and the Master Servicer. Upon deposit of the Repurchase Price in the Master Servicer Collection 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 Paying Agent. The Trustee or the Custodian, as agent of the Trustee, 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 Trustee, to reflect such repurchase and shall promptly notify the Rating Agencies and the Master Servicer of such amendment. The obligation of the Seller to repurchase or substitute for any Mortgage Loan a Substitute 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 the Certificateholders, all of its right, title and interest in the Mortgage Loan Purchase Agreement, including but not limited to the Depositor’s rights and obligations pursuant to the Servicing Agreements (noting that the Seller has retained the right in the event of breach of the representations, warranties and covenants, if any, with respect to the related Mortgage Loans of the related Servicer under the related Servicing Agreement to enforce the provisions thereof and to seek all or any available remedies). The obligations of the Seller to substitute or repurchase, as applicable, a Mortgage Loan shall be the Trustee’s and the Certificateholders’ sole remedy for any breach thereof. At the request of the Trustee, the Depositor shall take such actions as may be necessary to enforce the above right, title and interest on behalf of the Trustee and the Certificateholders or shall execute such further documents as the Trustee may reasonably require in order to enable the Trustee to carry out such enforcement.

(b) If the Depositor, the Securities Administrator 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 Trustee; provided, however, that if there is a breach of any representation set forth in the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, and the Mortgage Loan or the related property acquired with respect thereto has been sold, then the Seller shall pay, in lieu of the Repurchase Price, any excess of the Repurchase Price over the Net Liquidation Proceeds received upon such sale. If the Net Liquidation Proceeds exceed the Repurchase Price, any excess shall be paid to the Seller to the extent not required by law to be paid to the borrower. Any such purchase by the Seller shall be made by providing an amount equal to the Repurchase Price to the Master Servicer for deposit in the Master Servicer Collection Account and written notification detailing the components of such Repurchase Price to the Trustee, the Paying Agent and the Master Servicer. The Depositor shall notify the Trustee and submit to the Custodian, as agent for the Trustee, a Request for Release, and the Custodian 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 Master Servicer shall amend the Mortgage Loan Schedule to reflect such repurchase and shall promptly notify the Trustee and the Rating Agencies of such amendment. Enforcement of the obligation of the Seller to purchase (or substitute a Substitute Mortgage Loan for) any Mortgage Loan or any property acquired with respect thereto (or pay the Repurchase Price as set forth in the above proviso) as to which a breach has occurred and is continuing shall constitute the sole remedy respecting such breach available to the Certificateholders or the Trustee on their behalf.

Section 2.04

Substitution of Mortgage Loans.

Notwithstanding anything to the contrary in this Agreement, in lieu of purchasing a Mortgage Loan pursuant to the Mortgage Loan Purchase Agreement or Sections 2.02 or 2.03 of this Agreement, the Seller may, no later than the date by which such purchase by the Seller would otherwise be required, tender to the Trustee a Substitute Mortgage Loan accompanied by a certificate of an authorized officer of the Seller that such Substitute Mortgage Loan conforms to the requirements set forth in the definition of “Substitute Mortgage Loan” in this Agreement; 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) of the Code, any such cure or substitution must occur within 90 days from the date the breach was discovered. The Custodian, as agent for the Trustee, 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 fifth sentence of Subsection 2.02(a). Within two Business Days after

such notification, the Seller shall provide to the Paying Agent 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 Custodian of a Request for Release for such Mortgage Loan), 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 to the Custodian the documents related to the Substitute Mortgage Loan in accordance with the provisions of the Mortgage Loan Purchase Agreement or Subsections 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 Subsections. 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. The Master Servicer shall amend the Mortgage Loan Schedule to reflect such substitution and shall provide a copy of such amended Mortgage Loan Schedule to the Trustee and the Rating Agencies.

Section 2.05

Issuance of Certificates.

(a) The Trustee acknowledges the assignment to it of the Mortgage Loans and the other assets comprising the Trust Fund and, concurrently therewith, the Securities Administrator 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 Group I Mortgage Loans and the other assets of REMIC I for the benefit of the holders of the REMIC I Interests. The Trustee acknowledges receipt of such assets and declares that it holds and will hold the same in trust for the exclusive use and benefit of the holders of the REMIC I Interests.

(c) 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 Group II Mortgage Loans and the other assets of REMIC II for the benefit of the holders of the REMIC II Interests. The Trustee acknowledges receipt of such assets 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 Interests.

(d) 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, the REMIC II Regular Interests and the other assets of REMIC III for the benefit of the Holders of the Certificates (other than the Class R-I Certificates and the Class R-II Certificates). The Trustee acknowledges receipt of the REMIC I Regular Interests (which are uncertificated), the REMIC II Regular Interests (which are uncertificated) and the other assets of REMIC III and declares that it holds and will hold the same in trust for the exclusive use and benefit of the Holders of the Certificates (other than the Class R-I Certificates and the Class R-II Certificates).

ARTICLE III

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

Section 3.01

Master Servicer.

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

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

The Trustee or the Custodian, as its agent, shall provide access to the records and documentation in the possession of the Custodian 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 Custodian; provided, however, that, unless otherwise required by law, the Trustee or the Custodian, as its agent, 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 or the Custodian, as its agent, 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 or the Custodian’s actual costs.

The Trustee shall execute and deliver to the related Servicer and the Master Servicer any court pleadings, requests for trustee’s sale or other documents necessary or desirable to (i) the foreclosure or trustee’s sale with respect to a Mortgaged Property; (ii) any legal action brought to

obtain judgment against any Mortgagor on the Mortgage Note or Security Instrument; (iii) obtain a deficiency judgment against the Mortgagor; or (iv) enforce any other rights or remedies provided by the Mortgage Note or Security Instrument or otherwise available at law or equity.

Section 3.02

REMIC-Related Covenants.

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

Section 3.03

Monitoring of Servicers.

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

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

indemnity for its costs and expenses in pursuing such action. Nothing herein shall impose any obligation on the part of the Trustee to assume or succeed to the duties or obligations of the Master Servicer.

(c) To the extent that the costs and expenses of the Master Servicer related to any termination of a Servicer, appointment of a successor Servicer or the transfer and assumption of servicing by the Master Servicer with respect to any Servicing Agreement (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the Servicer as a result of an event of default by such Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor servicer to service the Mortgage Loans in accordance with the related Servicing Agreement) are not fully and timely reimbursed by the terminated Servicer, the Master Servicer shall be entitled to reimbursement of such costs and expenses from the Master Servicer Collection Account.

(d) The Master Servicer shall require each Servicer to comply with the remittance requirements and other obligations set forth in the related Servicing Agreements.

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

Section 3.04

Fidelity Bond.

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

Section 3.05

Power to Act; Procedures.

The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article X hereof, to do any and all things that it may deem necessary or desirable in connection with the master servicing and administration of the Mortgage Loans, including but not limited to the power and authority (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, in each case, in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 3.03, shall not permit any Servicer to) knowingly or intentionally take any action, or fail to take (or fail to cause to be taken) any action reasonably within its

control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, may cause any REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon the Trust Fund (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) unless the Master Servicer has received an Opinion of Counsel (but not at the expense of the Master Servicer) to the effect that the contemplated action would not cause any REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon any REMIC. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney empowering the Master Servicer or any Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, to enable the Master Servicer to master service and administer the Mortgage Loans and carry out its duties hereunder, in each case in accordance with Accepted Master Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Master Servicer or any Servicer). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 9.11 hereof. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action in the name of the Trustee, be deemed to be the agent of the Trustee.

Section 3.06

Due-on-Sale Clauses; Assumption Agreements.

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

Section 3.07

Release of Mortgage Files.

(a) Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by any Servicer of a notification that payment in full has been escrowed in a manner customary for such purposes for payment to Certificateholders on the next Distribution Date, the Servicer will, if required under the applicable Servicing Agreement (or if the Servicer does not, the Master Servicer may), promptly furnish to the Custodian, on behalf of the Trustee, two copies of a certification substantially in the form of Exhibit D hereto signed by a Servicing Officer or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer (which certification shall include a statement to the effect that all amounts received in connection with such payment that are required to be deposited in the Protected

Account maintained by the applicable Servicer pursuant to Section 4.01 or by the applicable Servicer pursuant to its Servicing Agreement have been or will be so deposited) and shall request that the Custodian, on behalf of the Trustee, deliver to the applicable Servicer the related Mortgage File. Upon receipt of such certification and request, the Custodian, on behalf of the Trustee, shall promptly release the related Mortgage File to the applicable Servicer and the Trustee and Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, each Servicer is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the Protected Account.

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

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

(a) The Master Servicer and each Servicer (to the extent required by the related Servicing Agreement) shall transmit to the Trustee or Custodian such documents and instruments coming into the possession of the Master Servicer or such Servicer from time to time as are required by the terms hereof, or in the case of the Servicers, the applicable Servicing Agreement, to be delivered to the Trustee or Custodian. Any funds received by the Master Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer or by a Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit of the Trustee and the Certificateholders subject to the Master Servicer’s right to retain or withdraw from the Master Servicer Collection Account the Master Servicing Compensation and other amounts provided in this Agreement, and to the right of each Servicer to retain its Servicing Fee and other amounts as provided in the applicable Servicing Agreement. The Master Servicer shall, and (to the extent provided in the applicable Servicing Agreement) shall cause each Servicer to, provide access to information and

documentation regarding the Mortgage Loans to the Trustee, its agents and accountants at any time upon reasonable request and during normal business hours, and to Certificateholders that are savings and loan associations, banks or insurance companies, the Office of Thrift Supervision, the FDIC and the supervisory agents and examiners of such Office and Corporation or examiners of any other federal or state banking or insurance regulatory authority if so required by applicable regulations of the Office of Thrift Supervision or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during normal business hours at the offices of the Master Servicer designated by it. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

(b) All Mortgage Files and funds collected or held by, or under the control of, the Master Servicer, in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds or Insurance Proceeds, shall be held by the Master Servicer for and on behalf of the Trustee and the Certificateholders and shall be and remain the sole and exclusive property of the Trustee; provided, however, that the Master Servicer and each Servicer shall be entitled to setoff against, and deduct from, any such funds any amounts that are properly due and payable to the Master Servicer or such Servicer under this Agreement or the applicable Servicing Agreement.

Section 3.09

Standard Hazard Insurance and Flood Insurance Policies.

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

(b) Pursuant to Section 4.01 and 4.02, any amounts collected by the Servicers or the Master Servicer, or by any Servicer, under any insurance policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or released to the Mortgagor in accordance with the applicable Servicing Agreement) shall be deposited into the Master Servicer Collection Account, subject to withdrawal pursuant to Section 4.02 and 4.03. Any cost incurred by the Master Servicer or any Servicer in maintaining any such insurance if the Mortgagor defaults in its obligation to do so shall be added to the amount owing under the Mortgage Loan where the terms of the Mortgage Loan so permit; provided, however, that the addition of any such cost shall not be taken into account for purposes of calculating the distributions to be made to Certificateholders and shall be recoverable by the Master Servicer or such Servicer pursuant to Section 4.02 and 4.03.

Section 3.10

Presentment of Claims and Collection of Proceeds.

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

Section 3.11

Maintenance of the Primary Mortgage Insurance Policies.

(a) The Master Servicer shall not take, or permit any Servicer (to the extent such action is prohibited under the applicable Servicing Agreement) to take, any action that would result in noncoverage under any applicable Primary Mortgage Insurance Policy of any loss which, but for the actions of the Master Servicer or such Servicer, would have been covered thereunder. The Master Servicer shall use its best reasonable efforts to cause each Servicer (to the extent required under the related Servicing Agreement) to keep in force and effect (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance), primary mortgage insurance applicable to each Mortgage Loan in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable. The Master Servicer shall not, and shall not permit any Servicer (to the extent required under the related Servicing Agreement) to, cancel or refuse to renew any such Primary Mortgage Insurance Policy that is in effect at the date of the initial issuance of the Mortgage Note and is required to be kept in force hereunder except in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable.

(b) The Master Servicer agrees to present, or to cause each Servicer (to the extent required under the related Servicing Agreement) to present, on behalf of the Trustee and the Certificateholders, claims to the insurer under any Primary Mortgage Insurance Policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Primary Mortgage Insurance Policies respecting defaulted Mortgage Loans. Pursuant to Section 4.01 and 4.02, any amounts collected by the Master Servicer or any Servicer under any Primary Mortgage Insurance Policies shall be deposited in the Master Servicer Collection Account, subject to withdrawal pursuant to Sections 4.02 and 4.03.

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

The Trustee (or the Custodian, as directed by the Trustee), shall retain possession and custody of the originals (to the extent available) of any Primary Mortgage Insurance Policies, or certificate of insurance if applicable, and any certificates of renewal as to the foregoing as may be issued from time to time as contemplated by this Agreement. Until all amounts distributable in respect of the Certificates have been distributed in full and the Master Servicer otherwise has fulfilled its obligations under this Agreement, the Trustee (or its Custodian, if any, as directed by

the Trustee) shall also retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions of this Agreement. The Master Servicer shall promptly deliver or cause to be delivered to the Trustee (or the Custodian, as directed by the Trustee), upon the execution or receipt thereof the originals of any Primary Mortgage Insurance Policies, any certificates of renewal, and such other documents or instruments that constitute portions of the Mortgage File that come into the possession of the Master Servicer from time to time.

Section 3.13

Realization Upon Defaulted Mortgage Loans.

The Master Servicer shall cause each Servicer (to the extent required under the related Servicing Agreement) to foreclose upon, repossess or otherwise comparably convert the ownership of Mortgaged Properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments, all in accordance with the applicable Servicing Agreement.

Section 3.14

Compensation for the Master Servicer.

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 remits to the Master Servicer a payment for deposit in the Master Servicer Collection Account covering the amount of the Repurchase Price for such 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 Master Servicer Collection 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.

CERTIFICATES

Section 5.01

Certificates.

(a) The Depository, the Depositor and the Securities Administrator have entered into a Depository Agreement dated as of the Closing Date (the “Depository Agreement”). Except for the Residual Certificates, the Private Certificates and the Individual Certificates and as provided in Subsection 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 Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar 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 Certificate Registrar cause such Class to become Global Certificates, the Certificate Registrar 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 Certificate Registrar in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository and (B) the Certificate Registrar or the Depositor is unable to locate a qualified successor within 30 days or (ii) the Depositor at its option advises the Certificate Registrar in writing that it elects to terminate the book-entry system through the Depository, the Certificate Registrar, as agent of the Depositor, 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 Certificate Registrar, as agent of the Depositor, of the Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Certificate Registrar shall issue the definitive Certificates. Neither the Depositor nor the Certificate Registrar shall be liable for any delay in delivery of any instructions required under this section and may conclusively rely on, and shall be protected in relying on, such instructions.

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 Fractional Undivided 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 Certificate Registrar to exchange or cause the exchange of the Certificate Owner’s interest in such Class of Certificates for an equivalent Fractional Undivided Interest in fully registered definitive form. Upon receipt by the Certificate Registrar of instructions from the Depository directing the Certificate Registrar to effect such exchange (such instructions to contain information regarding the Class of Certificates and the Current Principal Amount 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 Certificate Registrar), (i) the Certificate Registrar shall instruct the Depository to reduce the related Depository Participant’s account by the aggregate Current Principal Amount of the definitive Certificate, (ii) the Certificate Registrar shall execute, authenticate and deliver, in accordance with the registration and delivery instructions provided by the Depository, a definitive Certificate evidencing such Certificate Owner’s Fractional Undivided Interest in such Class of Certificates and (iii) the Certificate Registrar shall execute and authenticate a new Book-Entry Certificate reflecting the reduction in the Current Principal Amount of such Class of Certificates by the amount of the definitive Certificates.

All Certificates issued on the Closing Date shall be dated the Closing Date. All Certificates issued thereafter shall be dated the date of their countersignature.

The holder of a beneficial interest in a Global Certificate may, subject to the rules and procedures of the Depository, cause the Depository (or its nominee) to notify the Certificate Registrar in writing of a request for transfer or exchange of such beneficial interest for an Individual Certificate or Certificates. Following a proper request for transfer or exchange, the Certificate Registrar shall, within five Business Days of such request made at the Corporate Trust Office, sign, countersign and deliver at the Corporate Trust Office, to the transferee (in the case of transfer) or holder (in the case of exchange) or send by first class mail at the risk of the transferee (in the case of transfer) or holder (in the case of exchange) to such address as the transferee or holder, as applicable, may request, an Individual Certificate or Certificates, as the case may require, for a like aggregate Fractional Undivided Interest and in such authorized denomination or denominations as may be requested. The presentation for transfer or exchange of any Individual Certificate shall not be valid unless made at the Corporate Trust Office by the registered holder in person, or by a duly authorized attorney-in-fact.

(i) At the option of the Certificateholders, Certificates may be exchanged for other Certificates of authorized denominations of a like Class and aggregate Fractional Undivided Interest, upon surrender of the Certificates to be exchanged at the Corporate Trust Office; provided, however, that no Certificate may be exchanged for new Certificates unless the original Fractional Undivided Interest represented by each such new Certificate (i) is at least equal to the minimum authorized denomination or (ii) is acceptable to the Depositor as indicated to the Trustee in writing. Whenever any Certificates are so surrendered for exchange, the Certificate Registrar shall sign and countersign and the Certificate Registrar shall deliver the Certificates which the Certificateholder making the exchange is entitled to receive.

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

(k) No service charge shall be made for any transfer or exchange of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

The mutilated, destroyed, lost or stolen Certificate shall thereupon be canceled of record by the Certificate Registrar and shall be of no further effect and evidence no rights.

(b) Upon the issuance of any new Certificate under this Section 5.03, the Certificate Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Certificate Registrar) connected therewith. Any duplicate Certificate issued pursuant to this Section 5.03 shall constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 5.04

Persons Deemed Owners.

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

Section 5.05

Transfer Restrictions on Residual Certificates.

(a) Residual Certificates, or interests therein, may not be transferred without the prior express written consent of the Tax Matters Person and the Depositor. As a prerequisite to such consent, (1) the proposed transferee must provide the Tax Matters Person, the Depositor, the Certificate Registrar and the Trustee with an affidavit that the proposed transferee is a Permitted Transferee (and an affidavit that it is a United States Person), and (2) the proposed transferor must provide the Tax Matters Person, the Depositor, the Certificate Registrar and the Trustee with a certificate to the effect that it has no knowledge that the statements made by the proposed transferee in any such affidavit are false, each as provided in subsection (b) below.

(b) No transfer, sale or other disposition of a Residual Certificate (including a beneficial interest therein) may be made unless, prior to the transfer, sale or other disposition of a Residual Certificate, (1) the proposed transferee (including the initial purchasers thereof) delivers to the Tax Matters Person, the Trustee, the Certificate Registrar and the Depositor an affidavit in the form attached hereto as Exhibit E stating, among other things, that as of the date of such transfer (i) such transferee is a Permitted Transferee and that (ii) such transferee is not acquiring such Residual Certificate for the account of any Person who is not a Permitted Transferee, and (2) the proposed transferor delivers to the Tax Matters Person, the Trustee, the Certificate Registrar and the Depositor a certificate to the effect that it has no knowledge that the statements made by the proposed transferee in any such affidavit are false. The Tax Matters Person shall not consent to a transfer of a Residual Certificate if it has actual knowledge that any statement made in the affidavit issued pursuant to the preceding sentence is not true. Notwithstanding any transfer, sale or other disposition of a Residual Certificate to any Person who is not a Permitted Transferee, such transfer, sale or other disposition shall be deemed to be of no legal force or effect whatsoever and such Person shall not be deemed to be a Holder of a Residual Certificate for any purpose hereunder, including, but not limited to, the receipt of distributions thereon. If any purported transfer shall be in violation of the provisions of this Section 5.05(b), then the prior Holder thereof shall, upon discovery that the transfer of such Residual Certificate was not in fact permitted by this Section 5.05(b), be restored to all rights as a Holder thereof retroactive to the date of the purported transfer. None of the Trustee, the Certificate Registrar, the Tax Matters Person or the Depositor shall be under any liability to any Person for any registration or transfer of a Residual Certificate that is not permitted by this Section 5.05(b) or for making payments due on such Residual Certificate to the purported Holder thereof or taking any other action with respect to such purported Holder under the provisions of this Agreement so long as

the written affidavit referred to above was received with respect to such transfer, and the Tax Matters Person, the Trustee, the Certificate Registrar and the Depositor, as applicable, had no knowledge that it was untrue. The prior Holder shall be entitled to recover from any purported Holder of a Residual Certificate that was in fact not a permitted transferee under this Section 5.05(b) at the time it became a Holder all payments made on such Residual Certificate. Each Holder of a Residual Certificate, by acceptance thereof, shall be deemed for all purposes to have consented to the provisions of this Section 5.05(b) and to any amendment of this Agreement deemed necessary (whether as a result of new legislation or otherwise) by counsel of the Tax Matters Person or the Depositor to ensure that the Residual Certificates are not transferred to any Person who is not a Permitted Transferee and that any transfer of such Residual Certificates will not cause the imposition of a tax upon the Trust or cause any REMIC to fail to qualify as a REMIC.

(c) The Residual Certificates (including a beneficial interest therein) may not be purchased by or transferred to any Person who is not a United States Person.

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

Section 5.06

Restrictions on Transferability of Certificates.

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

(b)	The Private Certificates shall each bear a Securities Legend.
Section 5.07		ERISA Restrictions.

(a) Subject to the provisions of subsection (b), no Residual Certificates or Private Certificates may be acquired directly or indirectly by, or on behalf of, an employee benefit plan or other retirement arrangement which is subject to Title I of ERISA or Section 4975 of the Code, unless the proposed transferee provides either (i) the Trustee or the Securities

Administrator, with an Opinion of Counsel addressed to the Depositor, the Trustee, the Certificate Registrar, the Master Servicer and the Securities Administrator (upon which they may rely) which is satisfactory to the Trustee or the Securities Administrator, which opinion will not be at the expense of the Depositor, the Trustee, the Certificate Registrar, the Master Servicer or the Securities Administrator, that the purchase of such Certificates by or on behalf of such Plan is permissible under applicable law, will not constitute or result in a nonexempt prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Depositor, the Master Servicer, the Certificate Registrar, the Securities Administrator or the Trustee to any obligation in addition to those undertaken in the Agreement or (ii) in the case of the Private Certificates, a representation or certification to the Certificate Registrar (upon which the Trustee and the Certificate Registrar are authorized to rely) to the effect that the proposed transfer and holding of such a Certificate and the servicing, management and operation of the Trust: (I) will not result in a prohibited transaction under Section 406 of ERISA or Section 4975 of the Code which is not covered under an individual or class prohibited transaction exemption including but not limited to Department of Labor Prohibited Transaction Exemption (“PTE”) 84-14 (Class Exemption for Plan Asset Transactions Determined by Independent Qualified Professional Asset Managers); PTE 91-38 (Class Exemption for Certain Transactions Involving Bank Collective Investment Funds); PTE 90-1 (Class Exemption for Certain Transactions Involving Insurance Company Pooled Separate Accounts), PTE 95-60 (Class Exemption for Certain Transactions Involving Insurance Company General Accounts), and PTCE 96-23 (Class Exemption for Plan Asset Transactions Determined by In-House Asset Managers and (II) will not subject the Depositor, the Securities Administrator, the Master Servicer or the Trustee to any obligation in addition to those undertaken in the Agreement.

(b) Any Person acquiring an interest in a Global Certificate which is a Private Certificate, by acquisition of such Certificate, shall be deemed to have represented to the Trustee that either: (i) it is not acquiring an interest in such Certificate directly or indirectly by, or on behalf of, an employee benefit plan or other retirement arrangement which is subject to Title I of ERISA or Section 4975 of the Code, or (ii) the transfer and holding of an interest in such Certificate to that Person and the subsequent servicing, management and operation of the Trust and its assets: (I) will not result in any prohibited transaction which is not covered under an individual or class prohibited transaction exemption, including, but not limited to, PTE 84-14, PTE 91-38, PTE 90-1, PTE 95-60 or PTE 96-23 and (II) will not subject the Depositor, the Securities Administrator, the Master Servicer or the Trustee to any obligation in addition to those undertaken in the Agreement.

(c) Each beneficial owner of a Class I-B-1, Class I-B-2, Class I-B-3, Class II-B-1, Class II-B-2 or Class II-B-3 Certificate or any interest therein shall be deemed to have represented, by virtue of its acquisition or holding of that certificate or interest therein, that either (i) it is not a Plan or investing with “Plan Assets”, (ii) it has acquired and is holding such certificate in reliance on Prohibited Transaction Exemption 90-30, as amended from time to time (the “Exemption”), and that it understands that there are certain conditions to the availability of the Exemption, including that the certificate must be rated, at the time of purchase, not lower than “BBB-” (or its equivalent) by S&P or Moody’s Investors Service, Inc., and the certificate is so rated or (iii) (1) it is an insurance company, (2) the source of funds used to acquire or hold the certificate or interest therein is an “insurance

company general account,” as such term is defined in Prohibited Transaction Class Exemption (“PTCE”) 95-60, and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

(d) Neither the Trustee, the Certificate Registrar, the Master Servicer nor the Securities Administrator will be required to monitor, determine or inquire as to compliance with the transfer restrictions with respect to the Global Certificates. Any attempted or purported transfer of any Certificate in violation of the provisions of Subsections (a) or (b) above shall be void ab initio and such Certificate shall be considered to have been held continuously by the prior permitted Certificateholder. Any transferor of any Certificate in violation of such provisions, shall indemnify and hold harmless the Trustee, the Certificate Registrar, the Securities Administrator and the Master Servicer from and against any and all liabilities, claims, costs or expenses incurred by the Trustee, the Certificate Registrar, the Securities Administrator or the Master Servicer as a result of such attempted or purported transfer. Neither the Trustee, nor the Certificate Registrar shall be liable for transfer of any such Global Certificates in or through book-entry facilities of any Depository or between or among Depository Participants or Certificate Owners made in violation of the transfer restrictions set forth herein.

Section 5.08

Rule 144A Information.

For so long as any Certificates are outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) of the Securities Act, (1) the Depositor will provide or cause to be provided to any holder of such Certificates and any prospective purchaser thereof designated by such a holder, upon the request of such holder or prospective purchaser, the information required to be provided to such holder or prospective purchaser by Rule 144A(d)(4) under the Securities Act; and (2) the Depositor shall update such information from time to time in order to prevent such information from becoming false and misleading and will take such other actions as are necessary to ensure that the safe harbor exemption from the registration requirements of the Securities Act under Rule 144A is and will be available for resales of such Certificates conducted in accordance with Rule 144A.

Section 5.09

Appointment of Paying Agent and Certificate Registrar.

Wells Fargo Bank, National Association, as Securities Administrator, shall act as the initial Paying Agent and Certificate Registrar for so long as it is also the Master Servicer. Each of the Paying Agent and the Certificate Registrar may resign upon thirty (30) days’ prior written notice to the Trustee; provided hereto that no such resignation shall be effective until the appointment of a successor paying agent or certificate registrar. In the event the Paying Agent and/or the Certificate Registrar resigns or is removed by the Trustee for cause, the Trustee may appoint a successor paying agent or certificate registrar, as applicable. The Trustee shall cause such successor paying agent, if other than the Trustee or the Master Servicer or the Securities Administrator, to execute and deliver to the Trustee an instrument in which such paying agent shall agree with the Trustee that such paying agent will hold all sums held by it for the payment to Certificateholders in trust for the benefit of the Certificateholders entitled thereto until such sums have been paid to the Certificateholders.

(G) On each Distribution Date prior to the Group II Cross-Over Date but after the reduction of the Current Principal Amount of all of the Senior Certificates of a Group II Certificate Group or Groups to zero, the remaining Class or Classes of Senior Certificates in the remaining Group II Certificate Groups will be entitled to receive in reduction of their Current Principal Amounts, pro rata based upon their Current Principal Amounts immediately prior to such Distribution Date, in addition to any Principal Prepayments related to such remaining Senior Certificates’ respective Loan Group allocated to such Senior Certificates, 100% of the Principal Prepayments on any Group II Mortgage Loan in the Loan Group relating to the Class or Classes of Senior Certificates of the fully repaid Group II Certificate Group; provided, however, that if (A) the weighted average of the Subordinate Percentages of the Group II Subordinate Certificates on such Distribution Date equals or exceeds two times the initial weighted average of the Subordinate Percentages of the Group II Subordinate Certificates and (B) the aggregate Scheduled Principal Balance of the Group II Mortgage Loans delinquent 60 days or more (including for this purpose any such Group II Mortgage Loans in foreclosure and bankruptcy and Group II 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 Group II Subordinate Certificates does not exceed 50%, then the additional allocation of Principal Prepayments to the Group II-1, Group II-2, Group II-3, Group II-4 and Group II-5 Senior Certificates in accordance with this clause (a)(ii)(G) will not be made and 100% of the Principal Prepayments on any Mortgage Loan in the Loan Group relating to the fully repaid Class or Classes of Senior Certificates will be allocated to the Group II Subordinate Certificates.

(H) If on any Distribution Date on which the aggregate Current Principal Amount of the Group II-1, Group II-2, Group II-3, Group II-4 or Group II-5 Senior Certificates would be greater than the aggregate Scheduled Principal Balance of the Mortgage Loans in the related Loan Group and any Group II Subordinate Certificates are still outstanding, in each case after giving effect to distributions to be made on such Distribution Date, (A) 100% of amounts otherwise allocable to the Group II Subordinate Certificates in respect of principal will be distributed to the Group II-1, Group II-2, Group II-3, Group II-4 or Group II-5 Senior Certificates in reduction of the Current Principal Amounts thereof, until the aggregate Current Principal Amount of such Class or Classes of Group II-1, Group II-2, Group II-3, Group II-4 or

Group II-5 Senior Certificates is an amount equal to the aggregate Scheduled Principal Balance of the Mortgage Loans in the related Loan Group, and (B) the Accrued Certificate Interest otherwise allocable to the Subordinate Certificates on such Distribution Date will be reduced, if necessary, and distributed to such Class or Classes of Senior Certificates in an amount equal to the Accrued Certificate Interest for such Distribution Date on the excess of (x) the aggregate Current Principal Amount of such Class or Classes of Senior Certificates over (y) the aggregate Scheduled Principal Balance of the Mortgage Loans in the Loan Group II. Any such reduction in the Accrued Certificate Interest on the Group II Subordinate Certificates will be allocated in reverse order of the Subordinate Certificates numerical designations, commencing with the Class II-B-6 Certificates.

(I) If, after distributions have been made pursuant to priorities first and second of clauses (a)(ii)(A), (B), (C), (D) and (E) above on any Distribution Date, the remaining Group II-1, Group II-2, Group II-3, Group II-4 or Group II-5 Available Funds are less than the Group II-1, Group II-2, Group II-3, Group II-4 or Group II-5 Senior Optimal Principal Amounts for the Group II-1, Group II-2, Group II-3, Group II-4 or Group II-5 Senior Certificates, respectively, the Senior Optimal Principal Amount for such Loan Group shall be reduced, and such remaining Available Funds will be distributed on the related Senior Certificates, on a pro rata basis, on the basis of such reduced amount.

(J) On each Distribution Date, any Group II Available Funds remaining after payment of interest and principal to the Classes of Certificates entitled thereto, as described above, will be distributed to the Class R-II Certificates; provided that if on any Distribution Date there are any Group II-1, Group II-2, Group II-3, Group II-4 or Group II-5 Available Funds remaining after payment of interest and principal to a Class or Classes of Certificates entitled thereto, such amounts will be distributed to the other Classes of Group II Senior Certificates, pro rata, based upon their Current Principal Amounts, until all amounts due to all Classes of Group II Senior Certificates have been paid in full, before any amounts are distributed to the Class R-II Certificates.

(K) For any Distribution Date, “pro rata” distributions among Classes of Certificates in respect of Accrued Certificate Interest or unpaid Accrued Certificate Interest will be made in proportion to the amount of Accrued Certificate Interest or unpaid Accrued Certificate Interest, respectively, due on such Classes for such Distribution Date. For any Distribution Date, “pro rata” distributions among Classes of Certificates in respect of principal will be made in proportion to the Current Principal Amount of such Classes immediately prior to such Distribution Date.

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

(M) If on any Distribution Date the Available Funds for the Senior Certificates in any Certificate Group is less than the Accrued Certificate Interest on the related Senior Certificates for such Distribution Date prior to reduction for Net Interest Shortfalls and the interest portion of Realized Losses, the shortfall will be allocated among the holders of each Class of Senior Certificates in such Certificate Group in proportion to the respective amounts of

Accrued Certificate Interest that would have been allocated thereto in the absence of such Net Interest Shortfalls and/or Realized Losses for such Distribution Date. In addition, the amount of any interest shortfalls will constitute unpaid Accrued Certificate Interest and will be distributable to holders of the Certificates of the related Classes entitled to such amounts on subsequent Distribution Dates, to the extent of the applicable Available Funds after current interest distributions as required herein. Any such amounts so carried forward will not bear interest. Shortfalls in interest payments will not be offset by a reduction in the servicing compensation of the Master Servicer or otherwise, except to the extent of applicable Compensating Interest Payments.

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

Section 6.02

Allocation of Losses.

(a) On or prior to each Determination Date, the Master Servicer shall determine the amount of any Realized Loss in respect of each Mortgage Loan that occurred during the immediately preceding calendar month, based on information provided by the related Servicer.

(b) With respect to any Group I Certificates (other than the Interest Only Certificates) on any Distribution Date, the principal portion of each Realized Loss on a Group I Mortgage Loan shall be allocated as follows:

first, to the Class I-B-6 Certificates, until the Current Principal Amount thereof has been reduced to zero;

second, to the Class I-B-5 Certificates, until the Current Principal Amount thereof has been reduced to zero;

third, to the Class I-B-4 Certificates, until the Current Principal Amount thereof has been reduced to zero;

fourth, to the Class I-B-3 Certificates, until the Current Principal Amount thereof has been reduced to zero;

fifth, to the Class I-B-2 Certificates, until the Current Principal Amount thereof has been reduced to zero; and

sixth, to the Class I-B-1 Certificates, until the Current Principal Amount thereof has been reduced to zero.

Thereafter, the principal portion of Realized Losses on the Group I-1, Group I-2 and Group I-3 Mortgage Loans will be allocated on any Distribution Date to the Class or Classes of Senior Certificates of the related Certificate Group, pro rata, based upon their respective Current Principal Amounts; provided, that the principal portion of Realized Losses allocable to the Class I-1-A-1 Certificates on a Distribution Date will first be allocated to the Class I-1-A-2 Certificates until the Current Principal Amount of such

Class has been reduced to zero, and then to the Class, I-1-A-1 Certificates, until the Current Principal Amount there has been reduced to zero; provided further, that the principal portion of Realized Losses allocable to the Class I-2-A-1 Certificates on a Distribution Date will first be allocated to the Class I-2-A-2 Certificates until the Current Principal Amount of such Class has been reduced to zero, and then to the Class, I-2-A-1 Certificates, until the Current Principal Amount there has been reduced to zero; provided further, that the principal portion of Realized Losses allocable to the Class I-3-A-1 Certificates on a Distribution Date will first be allocated to the Class I-3-A-2 Certificates until the Current Principal Amount of such Class has been reduced to zero, and then to the Class, I-3-A-1 Certificates, until the Current Principal Amount there has been reduced to zero. Once the Group I-1, Group I-2 or Group I-3 Senior Certificates have been reduced to zero, the principal portion of Realized Losses on the Mortgage Loans in the related Loan Group (if any) will be allocated on a pro rata basis to the remaining Group I Senior Certificates of the other Certificate Groups.

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

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

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

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

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

fifth, to the Class II-B-2 Certificates, until the Current Principal Amount thereof has been reduced to zero; and

sixth, to the Class II-B-1 Certificates, until the Current Principal Amount thereof has been reduced to zero.

Thereafter, the principal portion of Realized Losses on the Group II-1, Group II-2, Group II-3, Group II-4 and Group II-5 Mortgage Loans will be allocated on any Distribution Date to the Class or Classes of Senior Certificates of the related Certificate Group, pro rata, based upon their respective Current Principal Amounts; provided, that the principal portion of Realized Losses allocable to the Class II-2-A-1 Certificates on a Distribution Date will first be allocated to the Class II-2-A-2 Certificates until the Current Principal Amount of such Class has been reduced to zero, and then to the Class, II-2-A-1 Certificates, until the Current Principal Amount there has been reduced to zero; provided further, that the principal portion of Realized Losses allocable to the Class II-3-A-1 Certificates on a Distribution Date will first be allocated to the Class II-3-A-2 Certificates until the Current Principal Amount of such Class has been reduced to zero, and then to

the Class, II-3-A-1 Certificates, until the Current Principal Amount there has been reduced to zero. Once the Group II-1, Group II-2, Group II-3, Group II-4 or Group II-5 Senior Certificates have been reduced to zero, the principal portion of Realized Losses on the Mortgage Loans in the related Loan Group (if any) will be allocated on a pro rata basis to the remaining Group II Senior Certificates of the other Certificate Groups.

(d) Notwithstanding the foregoing clause (c), no such allocation of any Realized Loss shall be made on a Distribution Date to any Class of Group I Certificates to the extent that such allocation would result in the reduction of the aggregate Current Principal Amounts of all the Group I Certificates (other than the Class R-I Certificates) as of such Distribution Date, after giving effect to all distributions and prior allocations of Realized Losses on the Group I Mortgage Loans on such date, to an amount less than the aggregate Scheduled Principal Balance of all of the Group I Mortgage Loans as of the first day of the month of such Distribution Date (such limitation, the “Group I Loss Allocation Limitation”), and (y) the foregoing clause (c), no such allocation of any Realized Loss shall be made on a Distribution Date to any Class of Group II Certificates to the extent that such allocation would result in the reduction of the aggregate Current Principal Amounts of all the Group II Certificates (other than the Class R-II Certificates and Class R-III Certificates) as of such Distribution Date, after giving effect to all distributions and prior allocations of Realized Losses on the Group II Mortgage Loans on such date, to an amount less than the aggregate Scheduled Principal Balance of all of the Group II Mortgage Loans as of the first day of the month of such Distribution Date (such limitation, the “Group II Loss Allocation Limitation”).

(e) Any Realized Losses allocated to a Class of Certificates shall be allocated among the Certificates of such Class in proportion to their respective Current Principal Amounts. Any allocation of Realized Losses shall be accomplished by reducing the Current Principal Amount of the related Certificates on the related Distribution Date.

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

(g) On each Distribution Date, the Securities Administrator shall determine and notify the Paying Agent of the Group I Subordinate Certificate Writedown Amount and the Group II Subordinate Certificate Writedown Amount. Any Group I Subordinate Certificate Writedown Amount shall effect a corresponding reduction in the Current Principal Amount of (i) if prior to the Group I Cross-Over Date, the Current Principal Amounts of the Group I Subordinate Certificates, in the reverse order of their numerical Class designations and (ii) from and after the Group I Cross-Over Date, the Group I Senior Certificates in accordance with priorities set forth in clause (b) above, which reduction shall occur on such Distribution Date after giving effect to distributions made on such Distribution Date. Any Group II Subordinate Certificate Writedown Amount shall effect a corresponding reduction in the Current Principal Amount of (i) if prior to the Group II Cross-Over Date, the Current Principal Amounts of the Group II Subordinate Certificates, in the reverse order of their numerical Class designations and (ii) from and after the Group II Cross-Over Date, the Group II Senior Certificates in accordance with priorities set forth in clause (c) above, which reduction shall occur on such Distribution Date after giving effect to distributions made on such Distribution Date.

(h) Any Net Interest Shortfall will be allocated among the Classes of Certificates (other than the Residual Certificates) in proportion to the respective amounts of Accrued Certificate Interest that would have been allocated thereto in the absence of such Net Interest Shortfall for such Distribution Date. The interest portion of any Realized Losses with respect to the Group I Mortgage Loans or Group II Mortgage Loans occurring on or prior to the Group I Cross-Over Date or Group II Cross-Over Date, respectively, will not be allocated among any Certificates, but will reduce the amount of Group I Available Funds or Group II Available Funds, respectively, on the related Distribution Date. As a result of the subordination of the Group I Subordinate Certificates and Group II Subordinate Certificates in right of distribution, such Realized Losses on the Group I Mortgage Loans and Group II Mortgage Loans will be borne by the Group I Subordinate Certificates and Group II Subordinate Certificates, respectively, in inverse order of their numerical Class designations. Following the Group I Cross-Over Date, the interest portion of Realized Losses on the Group I Mortgage Loans will be allocated to the Group I Senior Certificates in the manner described in the first sentence of this clause (i). Following the Group II Cross-Over Date, the interest portion of Realized Losses on the Group II Mortgage Loans will be allocated to the Group II Senior Certificates in the manner described in the first sentence of this clause (i).

Section 6.03

Payments.

(a) On each Distribution Date, other than the final Distribution Date, the Paying Agent shall distribute to each Certificateholder of record as of the immediately preceding Record Date the Certificateholder’s pro rata share of its Class (based on the aggregate Fractional Undivided Interest represented by such Holder’s Certificates) of all amounts required to be distributed on such Distribution Date to such Class, based on information provided to the Paying Agent by the Securities Administrator. The Securities Administrator shall calculate the amount to be distributed to each Class and, based on such amounts, the Securities Administrator shall determine the amount to be distributed to each Certificateholder. All of the Securities Administrator’s calculations of payments shall be based solely on information provided to the Securities Administrator by the Master Servicer. Neither the Securities Administrator nor the Paying Agent shall be required to confirm, verify or recompute any such information but shall be entitled to rely conclusively on such information.

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

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

In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund, and the Master Servicer shall be entitled to be reimbursed therefor out of the Master Servicer Collection

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

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

Master Servicer Not to Resign.

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

Section 7.06

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

No such assignment or delegation shall affect any liability of the Master Servicer arising prior to the effective date thereof.

ARTICLE VIII

DEFAULT

Section 8.01

Events of Default.

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

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

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

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

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

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

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

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

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

Section 8.02

Trustee to Act; Appointment of Successor.

(a) Upon the receipt by the Master Servicer of a notice of termination pursuant to Section 8.01 or an Opinion of Independent Counsel pursuant to Section 7.05 to the effect that the Master Servicer is legally unable to act or to delegate its duties to a Person which is legally able to act, the Trustee shall automatically become the successor in all respects to the Master Servicer in its capacity under this Agreement and the transactions set forth or provided for herein and shall thereafter be subject to all the responsibilities, duties, liabilities and limitations on liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof; provided, however, that the Company shall have the right to either (a) immediately assume the duties of the Master Servicer or (b) select a successor Master Servicer; provided further, however, that the Trustee shall have no obligation whatsoever with respect to any liability (other than advances deemed recoverable and not previously made) incurred by the Master Servicer at or prior to the time of termination. As compensation therefor, but subject to Section 7.06, the Trustee shall be entitled to compensation which the Master Servicer would have been entitled to retain if the Master Servicer had continued to act hereunder, except for those amounts due the Master Servicer as reimbursement permitted under this Agreement for advances previously made or expenses previously incurred. Notwithstanding the above, the Trustee may, if it shall be unwilling so to act, or shall, if it is legally unable so to act, appoint or petition a court of competent jurisdiction to appoint, any established housing and home finance institution which is a Fannie Mae- or Freddie Mac-approved servicer, and with respect to a successor to the Master Servicer only, having a net worth of not less than $10,000,000, as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder; provided, that the Trustee shall obtain a letter from each Rating Agency that the ratings, if any, on each of the Certificates will not be lowered as a result of the selection of the successor to the Master Servicer. Pending appointment of a successor to the Master Servicer hereunder, the Trustee shall act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on the Mortgage Loans as it and such successor shall agree; provided, however, that the provisions of Section 7.06 shall apply, the compensation shall not be in excess of that which the Master Servicer would have been entitled to if the Master Servicer had continued to act hereunder, and that such successor shall undertake and assume the obligations of the Trustee to pay compensation to any third Person acting as an agent or independent contractor in the performance of master servicing responsibilities hereunder. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

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

Section 8.03

Notification to Certificateholders.

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

Section 8.04

Waiver of Defaults.

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

Section 8.05

List of Certificateholders.

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

ARTICLE IX

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

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

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

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

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

Responsible Officers of the Trustee or an officer of the Securities Administrator, respectively, unless it shall be proved that the Trustee or the Securities Administrator, respectively, was negligent in ascertaining the pertinent facts;

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

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

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

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

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

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

(e) All funds received by the Master Servicer and the Trustee and required to be deposited in the Master Servicer Collection Account or Distribution Account pursuant to this Agreement will be promptly so deposited by the Master Servicer and the Trustee.

(f) Except for those actions that the Trustee or the Securities Administrator is required to take hereunder, neither the Trustee nor the Securities Administrator shall have any obligation or liability to take any action or to refrain from taking any action hereunder in the absence of written direction as provided hereunder.

Section 9.02

Certain Matters Affecting the Trustee and the Securities Administrator.

Except as otherwise provided in Section 9.01:

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

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

(iv) Prior to the occurrence of an Event of Default hereunder and after the curing or waiver of all Events of Default which may have occurred, neither the Trustee nor the Securities Administrator shall be liable in its individual capacity for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement;

(v) Neither the Trustee nor the Securities Administrator shall be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing to do so by Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust Fund and provided that the payment within a reasonable time to the Trustee or the Securities Administrator, as applicable, of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is,

in the opinion of the Trustee or the Securities Administrator, as applicable, reasonably assured to the Trustee or the Securities Administrator, as applicable, by the security afforded to it by the terms of this Agreement. The Trustee or the Securities Administrator may require reasonable indemnity against such expense or liability as a condition to taking any such action. The reasonable expense of every such examination shall be paid by the Certificateholders requesting the investigation;

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

(vii) Should the Trustee or the Securities Administrator deem the nature of any action required on its part, other than a payment or transfer under Subsection 4.01(b) or Section 4.02, to be unclear, the Trustee or the Securities Administrator, respectively, may require prior to such action that it be provided by the Depositor with reasonable further instructions;

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

Section 9.03 Trustee and Securities Administrator Not Liable for Certificates or Mortgage Loans.

The recitals contained herein and in the Certificates (other than the signature and countersignature of the Certificate Registrar on the Certificates) shall be taken as the statements of the Depositor, and neither the Trustee, or the Custodian on its behalf, nor the Securities Administrator shall have any responsibility for their correctness. Neither the Trustee nor the Securities Administrator makes any representation as to the validity or sufficiency of the Certificates (other than the signature and countersignature of the Certificate Registrar on the

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

Section 9.04

Trustee and Securities Administrator May Own Certificates.

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

Section 9.05

Trustee’s and Securities Administrator’s Fees and Expenses.

The fees and expenses of the Trustee and the Securities Administrator shall be paid in accordance with a side letter agreement between the Trustee and the Master Servicer. In addition, the Trustee and the Securities Administrator will be entitled to recover from the Master Servicer Collection Account pursuant to Section 4.03(b) all reasonable out-of-pocket expenses, disbursements and advances and the expenses of the Trustee and the Securities Administrator, respectively, in connection with any Event of Default, any breach of this Agreement or any claim or legal action (including any pending or threatened claim or legal action) or incurred or made by the Trustee or the Securities Administrator, respectively, in the administration of the trusts hereunder (including the reasonable compensation, expenses and disbursements of its counsel) except any such expense, disbursement or advance as may arise from its negligence or intentional misconduct or which is the responsibility of the Certificateholders. If funds in the Master Servicer Collection Account are insufficient therefor, the Trustee and the Securities Administrator shall recover such expenses from the Depositor and the Depositor hereby agrees to pay such expenses, disbursements or advances upon demand. Such compensation and

reimbursement obligation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust.

Section 9.06 Eligibility Requirements for Trustee, Paying Agent and Securities Administrator.

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

In case at any time the Trustee, the Paying Agent or the Securities Administrator shall cease to be eligible in accordance with the provisions of this Section 9.06, the Trustee or the Securities Administrator shall resign immediately in the manner and with the effect specified in Section 9.08.

(a) Any successor Trustee, Paying Agent or Securities Administrator appointed as provided in Section 9.08 shall execute, acknowledge and deliver to the Depositor and to its

predecessor Trustee, Paying Agent or Securities Administrator an instrument accepting such appointment hereunder. The resignation or removal of the predecessor Trustee, Paying Agent or Securities Administrator shall then become effective and such successor Trustee, Paying Agent or Securities Administrator, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee, Paying Agent or Securities Administrator herein. The predecessor Trustee, Paying Agent or Securities Administrator shall after payment of its outstanding fees and expenses promptly deliver to the successor Trustee, Paying Agent or Securities Administrator, as applicable, all assets and records of the Trust held by it hereunder, and the Depositor and the predecessor Trustee, Paying Agent or Securities Administrator, as applicable, shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor Trustee, Paying Agent or Securities Administrator, as applicable, all such rights, powers, duties and obligations.

Any state bank or trust company or national banking association into which the Trustee, Paying Agent or the Securities Administrator may be merged or converted or with which it may be consolidated or any state bank or trust company or national banking association resulting from any merger, conversion or consolidation to which the Trustee or the Securities Administrator, respectively, shall be a party, or any state bank or trust company or national banking association succeeding to all or substantially all of the corporate trust business of the Trustee, Paying Agent or the Securities Administrator, respectively, shall be the successor of the Trustee, Paying Agent or the Securities Administrator, respectively, hereunder, provided such state bank or trust company or national banking association shall be eligible under the provisions of Section 9.06. Such succession shall be valid without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 9.11

Appointment of Co-Trustee or Separate Trustee.

(a) Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust or property constituting the same may at the time be located, the Depositor and the Trustee acting jointly

shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee and the Depositor to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust, and to vest in such Person or Persons, in such capacity, such title to the Trust, or any part thereof, and, subject to the other provisions of this Section 9.11, such powers, duties, obligations, rights and trusts as the Depositor and the Trustee may consider necessary or desirable.

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

(c) No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor Trustee under Section 9.06 hereunder and no notice to Certificateholders of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 9.08 hereof.

(d) In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 9.11, all rights, powers, duties and obligations conferred or imposed upon the Trustee and required to be conferred on such co-trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee.

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

(f) To the extent not prohibited by law, any separate trustee or co-trustee may, at any time, request the Trustee, its agent or attorney-in-fact, with full power and authority, to do any lawful act under or with respect to this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor Trustee.

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

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

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

(b) The Securities Administrator shall prepare and file or cause to be filed with the Internal Revenue Service, and the Trustee shall sign, federal tax information returns or elections required to be made hereunder with respect to each REMIC, the Trust Fund, if applicable, and the Certificates containing such information and at the times and in the manner as may be required by the Code or applicable Treasury regulations, and shall furnish to each Holder of Certificates at any time during the calendar year for which such returns or reports are made such statements or information at the times and in the manner as may be required thereby, including, without limitation, reports relating to interest, original issue discount and market discount or premium (using a constant prepayment assumption of 25% CPR). The Securities Administrator will apply for an Employee Identification Number from the Internal Revenue Service under Form SS-4 or any other acceptable method for all tax entities. In connection with the foregoing, the Securities Administrator shall timely prepare and file, and the Trustee shall sign, Internal Revenue Service Form 8811, which shall provide the name and address of the person who can be contacted to obtain information required to be reported to the holders of regular interests in each REMIC (the “REMIC Reporting Agent”). The Trustee shall make elections to treat each REMIC as a REMIC (which elections shall apply to the taxable period ending December 31, 2005 and each calendar year thereafter) in such manner as the Code or applicable Treasury regulations may prescribe, and as described by the Securities Administrator. The Trustee shall sign all tax information returns filed pursuant to this Section and any other returns as may be required by the Code. The Holder of the Class R-I Certificates is hereby designated as the “Tax Matters Person” (within the meaning of Treasury Regulation Section 1.860F-4(d)) for REMIC I, the Holder of the Class R-II Certificates is hereby designated as the “Tax Matters Person” for REMIC II, and the Holder of the Class R-III Certificates is hereby designated as the “Tax Matters Person” for REMIC III. The Securities Administrator is hereby designated and appointed as the agent of each such Tax Matters Person. Any Holder of a Residual Certificate will by acceptance thereof appoint the Securities Administrator as agent and attorney-in-fact for the purpose of acting as Tax Matters Person for each REMIC during such time as the Securities Administrator does not own any such Residual Certificate. In the event that the Code or applicable Treasury regulations prohibit the Trustee from signing tax or information returns or other statements, or the Securities Administrator from acting as agent for the Tax Matters Person, the Trustee and the Securities Administrator shall take whatever action that in its sole good faith judgment is necessary for the proper filing of such information returns or for the provision of a Tax Matters Person, including designation of the Holder of a Residual Certificate to sign such returns or act as Tax Matters Person. Each Holder of a Residual Certificate shall be bound by this Section.

(c) The Securities Administrator shall provide upon request and receipt of reasonable compensation, such information as required in Section 860D(a)(6)(B) of the Code to the Internal Revenue Service, to any Person purporting to transfer a Residual Certificate to a Person other than a transferee permitted by Section 5.05(b), and to any regulated investment company, real

estate investment trust, common trust fund, partnership, trust, estate, organization described in Section 1381 of the Code, or nominee holding an interest in a pass-through entity described in Section 860E(e)(6) of the Code, any record holder of which is not a transferee permitted by Section 5.05(b) (or which is deemed by statute to be an entity with a disqualified member).

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

(e) Notwithstanding any other provision of this Agreement, the Trustee and the Securities Administrator shall comply with all federal withholding requirements respecting payments to Certificateholders of, or in respect of, interest or original issue discount on the Mortgage Loans that the Trustee or the Securities Administrator reasonably believes are applicable under the Code. The consent of Certificateholders shall not be required for such withholding. In the event the Trustee or the Securities Administrator withholds any amount from payments of, or in respect of, interest or original issue discount or advances thereof to any Certificateholder pursuant to federal withholding requirements, the Trustee or the Securities Administrator shall, together with its monthly report to such Certificateholders, indicate such amount withheld.

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

TERMINATION

Section 10.01 Termination Upon Repurchase by the Depositor or its Designee or Liquidation of the Mortgage Loans.

(a) Subject to Section 10.02, the respective obligations and responsibilities of the Depositor, the Trustee, the Paying Agent, the Master Servicer and the Securities Administrator created hereby, other than the obligation of the Paying Agent to make payments to Certificateholders as hereinafter set forth shall terminate with respect to Loan Group I and Loan Group II, as applicable, upon:

(i) the repurchase by or at the direction of the Depositor or its designee of all of the related Mortgage Loans and all related REO Property remaining in the Trust at a price (in each case, the “Termination Purchase Price”) equal to the sum of (a) 100% of the Outstanding Principal Balance of each such Mortgage Loan (other than any such Mortgage Loan related to REO Property) as of the date of repurchase, net of the principal portion of any unreimbursed Monthly Advances made by the purchaser, together with interest at the applicable Mortgage Interest Rate accrued but unpaid to, but not including, the first day of the month of repurchase, (b) the appraised value of any related REO Property, less the good faith estimate of the Depositor of liquidation expenses to be incurred in connection with its disposal thereof (but not more than the Outstanding Principal Balance of the related Mortgage Loan, together with interest at the applicable Mortgage Interest Rate accrued on that balance but unpaid to, but not including, the first day of the month of repurchase), such appraisal to be calculated by an appraiser mutually agreed upon by the Depositor and the Trustee at the expense of the Depositor, (c) unreimbursed out-of pocket costs of the Master Servicer, including unreimbursed servicing advances and the principal portion of any unreimbursed Monthly Advances, made on the related Mortgage Loans prior to the exercise of such repurchase right and (d) any unreimbursed costs and expenses of the Trustee related to related loans and the Securities Administrator payable pursuant to Section 9.05; or

(ii) the later of the making of the final payment or other liquidation, or any advance with respect thereto, of the last Mortgage Loan remaining in the portion of the Trust Fund related to the respective Certificate Group or the disposition of all property acquired with respect to any related Mortgage Loan; provided, however, that in the event that an advance has been made, but not yet recovered, at the time of such termination, the Person having made such advance shall be entitled to receive, notwithstanding such termination, any payments received subsequent thereto with respect to which such advance was made; or

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

(b) In no event, however, shall the Trust created hereby continue beyond the earlier of (i) the latest possible maturity date specified in Section 5.01(d) and (ii) the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James’s, living on the date of this Agreement.

(c) The right of the Depositor or its designee to repurchase all the assets of the Trust Fund as described in Subsection 10.01(a)(i) above is conditioned upon (i) such purchase occurring after the Distribution Date on which the aggregate Scheduled Principal Balance of the related Mortgage Loans is less than 10% of the sum of the aggregate Scheduled Principal Balance of the related Mortgage Loans as of the Cut-off Date, or (ii) the Depositor making a determination, based upon an Opinion of Counsel addressed to the Depositor, the Trustee and the Securities Administrator, that the REMIC status of REMIC I, REMIC II or REMIC III has been lost or that a substantial risk exists that such REMIC status will be lost for the then-current taxable year. At any time thereafter, in the case of (i) or (ii) above, the Depositor may elect to terminate REMIC I, REMIC II and REMIC III at any time, and upon such election, the Depositor or its designee, shall repurchase all the assets of the Trust Fund described in Subsection 10.01(a)(i) above.

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

(e) If the option of the Depositor to repurchase or cause the repurchase of all the assets in the Trust Fund as described in Subsection 10.01(a)(i) above, is exercised, the Depositor and/or its designee shall deliver to the Paying Agent for deposit in the Distribution Account, by the Business Day prior to the applicable Distribution Date, an amount equal to the Termination Purchase Price. Upon presentation and surrender of the related Certificates by the related Certificateholders, the Paying Agent shall distribute to such Certificateholders as directed by the Securities Administrator in writing an amount determined as follows: with respect to each Certificate (other than the Class R Certificates), the outstanding Current Principal Amount, plus with respect to each Certificate (other than the Class R Certificates), one month’s interest thereon at the applicable Pass-Through Rate; and with respect to the Class R Certificates, the percentage interest evidenced thereby multiplied by the difference, if any, between the above described repurchase price and the aggregate amount to be distributed to the Holders of the Certificates in such Certificate Group (other than the Class R Certificates). If the proceeds with respect to the Mortgage Loans of a Loan Group are not sufficient to pay all of the related Senior Certificates of the related Certificate Group in full, any such deficiency shall be allocated first, to the related Subordinate Certificates, in inverse order of their numerical designation and then to the related Senior Certificates of the related Certificate Group on a pro rata basis. Upon deposit of the Termination Purchase Price and following such final Distribution Date, the Trustee or the Custodian, as its agent, shall release promptly to the Depositor and/or its designee the Mortgage Files for the remaining Mortgage Loans, and the Accounts with respect thereto shall terminate, subject to the Paying Agent’s obligation to hold any amounts payable to the Certificateholders in

trust without interest pending final distributions pursuant to Subsection 10.01(g). Any other amounts remaining in the Accounts will belong to the Depositor.

(f) In the event that this Agreement is terminated with respect to some or all loans by reason of the payment or liquidation of all Mortgage Loans or the disposition of all property acquired with respect to all Mortgage Loans under Subsection 10.01(a)(ii) above, the Master Servicer shall deliver to the Paying Agent for deposit in the Distribution Account all distributable amounts remaining in the Master Servicer Collection Account. Upon the presentation and surrender of the Certificates, the Paying Agent shall distribute to the remaining Certificateholders, pursuant to the written direction of the Securities Administrator and in accordance with their respective interests, all distributable amounts remaining in the Distribution Account. Upon deposit by the Master Servicer of such distributable amounts, and following such final Distribution Date, the Paying Agent shall release promptly to the Depositor or its designee the Mortgage Files for the remaining Mortgage Loans, and the Master Servicer Collection Account and the Distribution Account shall terminate, subject to the Paying Agent’s obligation to hold any amounts payable to the Certificateholders in trust without interest pending final distributions pursuant to this Subsection 10.01(f).

(g) If not all of the Certificateholders shall surrender their Certificates for cancellation within six months after the time specified in the above-mentioned written notice, the Paying Agent shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice, not all the Certificates shall have been surrendered for cancellation, the Paying Agent may take appropriate steps, or appoint any agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets which remain subject to this Agreement.

Section 10.02

Additional Termination Requirements.

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

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

(ii) the Depositor shall notify the Trustee at the commencement of such 90-day liquidation period and, at or prior to the time of making of the final payment on the

Certificates, the Trustee shall sell or otherwise dispose of all of the remaining related assets of the Trust Fund in accordance with the terms hereof.

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

The parties intend that each of REMIC I, REMIC II and REMIC III shall be treated as a REMIC for federal income tax purposes and that the provisions of this Agreement should be construed in furtherance of this intent.

Section 11.02

Amendment.

(a) This Agreement may be amended from time to time by the Company, the Depositor, the Master Servicer, the Securities Administrator and the Trustee, without notice to or the consent of any of the Certificateholders, to cure any ambiguity, to correct or supplement any provisions herein or therein that may be defective or inconsistent with any other provisions herein or therein, to comply with any changes in the Code or to make any other provisions with respect to matters or questions arising under this Agreement which shall not be inconsistent with the provisions of this Agreement; provided, however, that such action shall not, as evidenced by an Opinion of Independent Counsel, addressed to the Trustee, adversely affect in any material respect the interests of any Certificateholder.

(b) This Agreement may also be amended from time to time by the Company, the Master Servicer, the Depositor, the Securities Administrator and the Trustee, with the consent of the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund or of the applicable Class or Classes, if such amendment affects only such Class or Classes, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Certificateholders; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments received on Mortgage Loans which are required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) reduce the aforesaid percentage of Certificates the Holders of which are required to consent to any such amendment, without the consent of the Holders of all Certificates then outstanding, or (iii) cause any REMIC to fail to qualify as a REMIC for federal income tax purposes, as evidenced by an Opinion of Independent Counsel addressed to the Trustee which shall be provided to the Trustee other than at the Trustee’s expense. Notwithstanding any other provision of this Agreement, for purposes of the giving or withholding of consents pursuant to this Section 12.02(b), Certificates registered in the name of or held for the benefit of the Depositor, the Securities Administrator, the Master Servicer, or the Trustee or any Affiliate thereof shall be entitled to vote their Fractional Undivided Interests with respect to matters affecting such Certificates.

(d) In the case of an amendment under Subsection 12.02(b) above, it shall not be necessary for the Certificateholders to approve the particular form of such an amendment.

Rather, it shall be sufficient if the Certificateholders approve the substance of the amendment. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe.

(e) Prior to the execution of any amendment to this Agreement, the Trustee shall be entitled to receive and rely upon an Opinion of Counsel addressed to the Trustee stating that the execution of such amendment is authorized or permitted by this Agreement.

Recordation of Agreement.

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

Section 11.04

Limitation on Rights of Certificateholders.

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

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

(c) No Certificateholder shall have any right by virtue of any provision of this Agreement to institute any suit, action or proceeding in equity or at law upon, under or with respect to this Agreement against the Depositor, the Securities Administrator, the Master Servicer or any successor to any such parties unless (i) such Certificateholder previously shall have given to the Trustee a written notice of a continuing default, as herein provided, (ii) the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such

reasonable indemnity as it may require against the costs and expenses and liabilities to be incurred therein or thereby, and (iii) the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding.

(d) No one or more Certificateholders shall have any right by virtue of any provision of this Agreement to affect the rights of any other Certificateholders or to obtain or seek to obtain priority or preference over any other such Certificateholder, or to enforce any right under this Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 12.04, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 11.05

Acts of Certificateholders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by Certificateholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Certificateholders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is expressly required, to the Depositor. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement and conclusive in favor of the Trustee and the Depositor, if made in the manner provided in this Section 12.05.

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

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

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action of the holder of any Certificate shall bind every future holder of the same Certificate and the holder of every Certificate issued upon the registration of transfer or exchange thereof, if applicable, or in lieu thereof with respect to anything done, omitted or suffered to be done by the Trustee, the Securities Administrator, the Depositor, the Master Servicer or any successor to any

such party in reliance thereon, whether or not notation of such action is made upon such Certificates.

(e) In determining whether the Holders of the requisite percentage of Certificates evidencing Fractional Undivided Interests have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Certificates owned by the Trustee, the Securities Administrator, the Depositor, the Master Servicer or any Affiliate thereof shall be disregarded, except as otherwise provided in Section 12.02(b) and except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Certificates which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Certificates which have been pledged in good faith to the Trustee, the Securities Administrator, the Depositor, the Master Servicer or any Affiliate thereof may be regarded as outstanding if the pledgor establishes to the satisfaction of the Trustee the pledgor’s right to act with respect to such Certificates and that the pledgor is not an Affiliate of the Trustee, the Securities Administrator, the Depositor, or the Master Servicer, as the case may be.

MORTGAGE PASS-THROUGH CERTIFICATE

SERIES 2005-12

evidencing a fractional undivided interest in the distributions allocable to the Class [_]-[_-[A]-_] Certificates with respect to a Trust Fund consisting primarily of a pool of adjustable rate mortgage loans secured by first liens on one-to-four family residential properties sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

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

This certifies that Cede & Co. is the registered owner of the Fractional Undivided Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in a trust (the “Trust Fund”) primarily consisting of adjustable rate mortgage loans secured by first liens on one- to four- family residential properties (collectively, the “Mortgage Loans”) sold by Structured Asset Mortgage Investments II Inc. (“SAMI II”). The Mortgage Loans were sold by EMC Mortgage Corporation (“EMC”) to SAMI II. Wells Fargo

Bank, N.A. (“Wells Fargo”) will act as master servicer and as securities administrator of the Mortgage Loans (the “Master Servicer” and the “Securities Administrator”, which terms include any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”), among SAMI II, as depositor (the “Depositor”), Wells Fargo, as Master Servicer and securities administrator (in such capacity, the “Securities Administrator”), EMC as seller and company and U.S. Bank National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

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

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

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

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

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

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Securities Administrator and the Trustee and the rights of the Certificateholders under the Agreement from time to time by the parties thereto with the consent of the Holders of Certificates, evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust Fund (or in certain cases, Holders of Certificates of affected Classes evidencing such percentage of the Fractional Undivided Interests thereof). Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

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

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

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

other assets of the Trust Fund in accordance with the terms of the Agreement. Such optional repurchase may be made only on or after the Distribution Date on which the aggregate unpaid principal balance of the Mortgage Loans is less than the percentage of the aggregate Outstanding Principal Balance specified in the Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right will effect the early retirement of the Certificates. In no event, however, will the Trust Fund created by the Agreement continue beyond the expiration of 21 years after the death of certain persons identified in the Agreement.

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

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

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

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

Mortgage Loans (the “Master Servicer” and the “Securities Administrator”, which terms include any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”), among SAMI II as depositor (the “Depositor”), Wells Fargo as Master Servicer and securities administrator (in such capacity, the “Securities Administrator”), EMC as seller and company and U.S. Bank National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

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

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

This certificate may not be acquired directly or indirectly by, or on behalf of, an employee benefit plan or other retirement arrangement which is subject to Title I of the Employee Retirement Income Security Act of 1974, as amended, or section 4975 of the Internal Revenue Code of 1986, as amended, unless the proposed transferee provides the Trustee with an opinion of counsel for the benefit of the Depositor, Master Servicer and the Securities Administrator and on which they may rely (which shall not be at the expense of the Trustee) which is acceptable to the Trustee, that the purchase of this Certificate will not result in or constitute a nonexempt prohibited transaction, is permissible under applicable law and will not give rise to any additional obligations on the part of the Seller, the Master Servicer, any Servicer, the Securities Administrator or the Trustee.

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

including the Class I-B-4, Class I-B-5, Class I-B-6, Class II-B-4, Class II-B-5 and Class II-B-6 Certificates (the “Privately Offered Certificates”)

Dear Ladies and Gentlemen:

In connection with our purchase of Privately Offered Certificates, we confirm that:

(i)

we understand that the Privately Offered Certificates are not being registered under the Securities Act of 1933, as amended (the “Act”) or any applicable state securities or “Blue Sky” laws, and are being sold to us in a transaction that is exempt from the registration requirements of such laws;

(ii)

any information we desired concerning the Certificates, including the Privately Offered Certificates, the trust in which the Certificates represent the entire beneficial ownership interest (the “Trust”) or any other matter we deemed relevant to our decision to purchase Privately Offered Certificates has been made available to us;

(iii)

we are able to bear the economic risk of investment in Privately Offered Certificates; we are an institutional “accredited investor” as defined in Section 501(a) of Regulation D promulgated under the Act and a sophisticated institutional investor;

(iv)

we are acquiring Privately Offered Certificates for our own account, not as nominee for any other person, and not with a present view to any distribution or other disposition of the Privately Offered Certificates;

(v)

we agree the Privately Offered Certificates must be held indefinitely by us (and may not be sold, pledged, hypothecated or in any way disposed of) unless subsequently registered under the Act and any applicable state

securities or “Blue Sky” laws or an exemption from the registration requirements of the Act and any applicable state securities or “Blue Sky” laws is available;

(vi)

we agree that in the event that at some future time we wish to dispose of or exchange any of the Privately Offered Certificates (such disposition or exchange not being currently foreseen or contemplated), we will not transfer or exchange any of the Privately Offered Certificates unless:

(A) (1) the sale is to an Eligible Purchaser (as defined below), (2) if required by the Pooling and Servicing Agreement (as defined below) a letter to substantially the same effect as either this letter or, if the Eligible Purchaser is a Qualified Institutional Buyer as defined under Rule 144A of the Act, the Rule 144A and Related Matters Certificate in the form attached to the Pooling and Servicing Agreement (as defined below) (or such other documentation as may be acceptable to the Trustee) is executed promptly by the purchaser and delivered to the addressees hereof and (3) all offers or solicitations in connection with the sale, whether directly or through any agent acting on our behalf, are limited only to Eligible Purchasers and are not made by means of any form of general solicitation or general advertising whatsoever; and

(B) if the Privately Offered Certificate is not registered under the Act (as to which we acknowledge you have no obligation), the Privately Offered Certificate is sold in a transaction that does not require registration under the Act and any applicable state securities or “blue sky” laws and, if U.S. Bank National Association (the “Trustee”) so requests, a satisfactory Opinion of Counsel is furnished to such effect, which Opinion of Counsel shall be an expense of the transferor or the transferee;

(vii)

we agree to be bound by all of the terms (including those relating to restrictions on transfer) of the Pooling and Servicing, pursuant to which the Trust was formed; we have reviewed carefully and understand the terms of the Pooling and Servicing Agreement;

(viii)

we either: (i) are not acquiring the Privately Offered Certificate directly or indirectly by, or on behalf of, an employee benefit plan or other retirement arrangement which is subject to Title I of the Employee Retirement Income Security Act of 1974, as amended, or section 4975 of the Internal Revenue Code of 1986, as amended, or (ii) are providing a representation to the effect that the proposed transfer and holding of a Privately Offered Certificate and the servicing, management and operation of the Trust and its assets: (I) will not result in any prohibited transaction which is not covered under an individual or class prohibited transaction exemption, including, but not limited to, Prohibited Transaction Exemption (“PTE”) 84-14, PTE 91-38, PTE 90-1, PTE 95-60, or PTE 96-23 and (II) will not

give rise to any additional obligations on the part of the Depositor, the Master Servicer, the Securities Administrator or the Trustee or (iii) have attached hereto the opinion specified in Section 5.07 of the Agreement.

(ix)

We understand that each of the Privately Offered Certificates bears, and will continue to bear, a legend to substantiate the following effect: “THIS CERTIFICATE HAS NOT BEEN AND WILL NOT BE REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER ANY STATE SECURITIES LAWS. THE HOLDER HEREOF, BY PURCHASING THIS CERTIFICATE, AGREES THAT THIS CERTIFICATE MAY BE REOFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY IN COMPLIANCE WITH THE SECURITIES ACT AND OTHER APPLICABLE LAWS AND ONLY (1) PURSUANT TO RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”) TO A PERSON THAT THE HOLDER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A (A “QIB”), PURCHASING FOR ITS OWN ACCOUNT OR A QIB PURCHASING FOR THE ACCOUNT OF A QIB, WHOM THE HOLDER HAS INFORMED, IN EACH CASE, THAT THE REOFFER, RESALE, PLEDGE OR OTHER TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (2) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (3) IN CERTIFICATED FORM TO AN “INSTITUTIONAL ACCREDITED INVESTOR” WITHIN THE MEANING THEREOF IN RULE 501(a)(1), (2), (3) or (7) OF REGULATION D UNDER THE ACT OR ANY ENTITY IN WHICH ALL OF THE EQUITY OWNERS COME WITHIN SUCH PARAGRAPHS PURCHASING NOT FOR DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, SUBJECT TO (A) THE RECEIPT BY THE TRUSTEE OF A LETTER SUBSTANTIALLY IN THE FORM PROVIDED IN THE AGREEMENT AND (B) THE RECEIPT BY THE TRUSTEE OF SUCH OTHER EVIDENCE ACCEPTABLE TO THE TRUSTEE THAT SUCH REOFFER, RESALE, PLEDGE OR TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT AND OTHER APPLICABLE LAWS OR IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS OF THE UNITED STATES AND ANY OTHER APPLICABLE JURISDICTION. THIS CERTIFICATE MAY NOT BE ACQUIRED DIRECTLY OR INDIRECTLY BY, OR ON BEHALF OF, AN EMPLOYEE BENEFIT PLAN OR OTHER RETIREMENT ARRANGEMENT WHICH IS SUBJECT TO TITLE I OF THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED, OR SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED, UNLESS THE PROPOSED TRANSFER AND HOLDING OF A CERTIFICATE AND THE

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements hereinafter set forth, the Trustee, the Depositor, the Master Servicer and the Custodian hereby agree as follows:

ARTICLE I.

DEFINITIONS

Capitalized terms used in this Agreement and not defined herein shall have the meanings assigned in the Original Pooling and Servicing Agreement, unless otherwise required by the context herein.

ARTICLE II.

CUSTODY OF MORTGAGE DOCUMENTS

Section 2.1. Custodian to Act as Agent: Acceptance of Mortgage Files. The Custodian, as the duly appointed custodial agent of the Trustee for these purposes, acknowledges (subject to any exceptions noted in the Initial Certification referred to in Section 2.3(a)), receipt of the Mortgage Files relating to the Mortgage Loans identified on the schedule attached hereto

(the “Mortgage Files”) and declares that it holds and will hold such Mortgage Files as agent for the Trustee, in trust, for the use and benefit of all present and future Certificateholders.

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

Section 2.3.

Review of Mortgage Files.

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

(b) Within 90 days of the Closing Date, the Custodian agrees, for the benefit of Certificateholders, to review, in accordance with the provisions of Section 2.02 of the Pooling and Servicing Agreement, each such document, and shall deliver to the Depositor and the Trustee an Interim Certification in the form annexed hereto as Exhibit Two to the effect that all such documents have been executed and received and that such documents relate to the Mortgage Loans identified on the Mortgage Loan Schedule, except for any exceptions listed on Schedule A attached to such Interim Certification. The Custodian shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable, or appropriate for the represented purpose or that they have actually been recorded or that they are other than what they purport to be on their face.

(c) Not later than 180 days after the Closing Date, the Custodian shall review the Mortgage Files as provided in Section 2.02 of the Pooling and Servicing Agreement and deliver to the Depositor and the Trustee a Final Certification in the form annexed hereto as Exhibit Three evidencing the completeness of the Mortgage Files.

(d) In reviewing the Mortgage Files as provided herein and in the Pooling and Servicing Agreement, the Custodian shall make no representation as to and shall not be responsible to verify (i) the validity, legality, enforceability, due authorization, recordability, sufficiency or genuineness of any of the documents included in any Mortgage File or (ii) the collectibility, insurability, effectiveness or suitability of any of the documents in any Mortgage File.

Upon receipt of written request from the Trustee, the Custodian shall as soon as practicable supply the Trustee with a list of all of the documents relating to the Mortgage Loans missing from the Mortgage Files.

Section 2.4. Notification of Breaches of Representations and Warranties. Upon discovery by the Custodian of a breach of any representation or warranty made by the Depositor as set forth in the Pooling and Servicing Agreement with respect to a Mortgage Loan relating to a Mortgage File, the Custodian shall give prompt written notice to the Depositor, the related Servicer and the Trustee.

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

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

From time to time as is appropriate for the servicing or foreclosure of any Mortgage Loan, including, for this purpose, collection under any Primary Insurance Policy, the related Servicer (or if the Servicer does not, the Master Servicer) shall deliver to the Custodian a Request for Release signed by a Servicing Officer requesting that possession of all of the Mortgage File be released to the related Servicer and certifying as to the reason for such release and that such release will not invalidate any insurance coverage provided in respect of the Mortgage Loan under any of the Insurance Policies. Upon receipt of the foregoing, the Custodian shall deliver the Mortgage File to the related Servicer. The related Servicer shall cause each Mortgage File or any document therein so released to be returned to the Custodian when the need therefore by the related Servicer no longer exists, unless (i) the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Master Servicer Collection Account or the Distribution Account or (ii) the Mortgage File or such document has been delivered to an attorney, or to a public trustee or other public official as required by law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially, and the related Servicer has delivered to the Custodian a certificate of a Servicing Officer certifying as to the name and address of the Person to which such Mortgage File or such document was delivered and the purpose or purposes of such delivery.

At any time that a Servicer is required to deliver to the Custodian a Request for Release, the Servicer shall deliver two copies of the Request for Release if delivered in hard copy or the Servicer may furnish such Request for Release electronically to the Custodian, in

which event the Servicing Officer transmitting the same shall be deemed to have signed the Request for Release. In connection with any Request for Release of a Mortgage File because of a repurchase of a Mortgage Loan, such Request for Release shall be followed by an assignment of mortgage, without recourse, representation or warranty from the Trustee to the Seller and the related Mortgage Note shall be endorsed without recourse by the Trustee and be returned to the Seller. In connection with any Request for Release of a Mortgage File because of the payment in full of a Mortgage Loan, such Request for Release shall be accompanied by a certificate of satisfaction or other similar instrument to be executed by or on behalf of the Trustee and returned to the related Servicer.

Section 2.6. Assumption Agreements. In the event that any assumption agreement, substitution of liability agreement or sale of servicing agreement is entered into with respect to any Mortgage Loan subject to this Agreement in accordance with the terms and provisions of the Pooling and Servicing Agreement, the Master Servicer, to the extent provided in the related Servicing Agreement, shall cause the related Servicer to notify the Custodian that such assumption or substitution agreement has been completed by forwarding to the Custodian the original of such assumption or substitution agreement, which shall be added to the related Mortgage File and, for all purposes, shall be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting parts thereof.

ARTICLE III.

CONCERNING THE CUSTODIAN

Section 3.1. Custodian as Bailee and Agent of the Trustee. With respect to each Mortgage Note, Mortgage and other documents constituting each Mortgage File which are delivered to the Custodian, the Custodian is exclusively the bailee and custodial agent of the Trustee and has no instructions to hold any Mortgage Note or Mortgage for the benefit of any person other than the Trustee and the Certificateholders and undertakes to perform such duties and only such duties as are specifically set forth in this Agreement and in the Pooling and Servicing Agreement. Except upon compliance with the provisions of Section 2.5 of this Agreement, no Mortgage Note, Mortgage or Mortgage File shall be delivered by the Custodian to the Depositor, the Servicers or the Master Servicer or otherwise released from the possession of the Custodian.

Section 3.2.

Section 3.4. Master Servicer to Pay Custodian’s Fees and Expenses. The Master Servicer covenants and agrees to pay to the Custodian from time to time, and the Custodian shall be entitled to, reasonable compensation for all services rendered by it in the exercise and performance of any of the powers and duties hereunder of the Custodian, and the Master Servicer will pay or reimburse the Custodian upon its request for all reasonable expenses, disbursements and advances incurred or made by the Custodian in accordance with any of the provisions of this Agreement (including the reasonable compensation and the expenses and

disbursements of its counsel and of all persons not regularly in its employ), except any such expense, disbursement or advance as may arise from its negligence or bad faith or to the extent that such cost or expense is indemnified by the Depositor pursuant to the Pooling and Servicing Agreement.

Section 3.5. Custodian May Resign Trustee May Remove Custodian. The Custodian may resign from the obligations and duties hereby imposed upon it as such obligations and duties relate to its acting as Custodian of the Mortgage Loans. Upon receiving such written notice of resignation, the Trustee shall either take custody of the Mortgage Files itself and give prompt written notice thereof to the Depositor, the Master Servicer and the Custodian, or promptly appoint a successor Custodian by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Custodian and one copy to the successor Custodian. If the Trustee shall not have taken custody of the Mortgage Files and no successor Custodian shall have been so appointed and have accepted appointment within 30 days after the giving of such written notice of resignation, the resigning Custodian may petition any court of competent jurisdiction for the appointment of a successor Custodian.

The Trustee may remove the Custodian at any time with the consent of the Master Servicer. In such event, the Trustee shall appoint, or petition a court of competent jurisdiction to appoint, a successor Custodian hereunder. Any successor Custodian shall be a depository institution subject to supervision or examination by federal or state authority, shall be able to satisfy the other requirements contained in Section 3.7 and shall be unaffiliated with the Servicer or the Depositor.

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

Section 3.6. Merger or Consolidation of Custodian. Any Person into which the Custodian may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Custodian shall be a party, or any Person succeeding to the business of the Custodian, shall be the successor of the Custodian hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 3.7. Representations of the Custodian. The Custodian hereby represents that it is a depository institution subject to supervision or examination by a federal or state authority, has a combined capital and surplus of at least $15,000,000 and is qualified to do business in the jurisdictions in which it will hold any Mortgage File.

ARTICLE IV.

For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument.

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

(b) Pursuant to various conveyancing documents to be executed on the Closing Date and pursuant to the Pooling and Servicing Agreement, the Purchaser will assign on the Closing Date all of its right, title and interest in and to the Mortgage Loans to the Trustee for the benefit of the Certificateholders. In connection with the transfer and assignment of the Mortgage Loans, the Mortgage Loan Seller has delivered or will deliver or cause to be delivered to the Trustee by the Closing Date or such later date as is agreed to by the Purchaser and the

Mortgage Loan Seller (each of the Closing Date and such later date is referred to as a “Mortgage File Delivery Date”), the items of each Mortgage File, provided, however, that in lieu of the foregoing, the Mortgage Loan Seller may deliver the following documents, under the circumstances set forth below: (i) in lieu of the original Security Instrument, assignments to the Trustee or intervening assignments thereof which have been delivered, are being delivered or will, upon receipt of recording information relating to the Security Instrument required to be included thereon, be delivered to recording offices for recording and have not been returned to the Mortgage Loan Seller in time to permit their delivery as specified above, the Mortgage Loan Seller may deliver a true copy thereof with a certification by the Mortgage Loan Seller, on the face of such copy, substantially as follows: “Certified to be a true and correct copy of the original, which has been transmitted for recording” (ii) in lieu of the Security Instrument, assignments to the Trustee or intervening assignments thereof, if the applicable jurisdiction retains the originals of such documents (as evidenced by a certification from the Mortgage Loan Seller to such effect) the Mortgage Loan Seller may deliver photocopies of such documents containing an original certification by the judicial or other governmental authority of the jurisdiction where such documents were recorded; (iii) in lieu of the Mortgage Notes relating to the Mortgage Loans, each identified in the list delivered by the Purchaser to the Trustee on the Closing Date and attached hereto as Exhibit 5, the Mortgage Loan Seller may deliver lost note affidavits and indemnities of the Mortgage Loan Seller; and (iv) the Mortgage Loan Seller shall not be required to deliver intervening assignments or Mortgage Note endorsements between the related Underlying Seller and the Mortgage Loan Seller, between the Mortgage Loan 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 Mortgage Loan Seller, in lieu of delivering the above documents, may deliver to the Trustee a certification by the Mortgage Loan Seller or the Master Servicer to such effect and shall deposit all amounts paid in respect of such Mortgage Loans in the Master Servicer Collection Account on the Closing Date. The Mortgage Loan Seller shall deliver such original documents (including any original documents as to which certified copies had previously been delivered) or such certified copies to the Trustee promptly after they are received. The Mortgage Loan Seller shall cause the Mortgage and intervening assignments, if any, and the assignment of the Security Instrument to be recorded not later than 180 days after the Closing Date, unless such assignment is not required to be recorded under the terms set forth in Section 6(a) hereof.

(c) In connection with the assignment of any Mortgage Loan registered on the MERS® System, the Mortgage Loan Seller further agrees that it will cause, at the Mortgage Loan Seller’s own expense, within 30 days after the Closing Date, the MERS® System to indicate that such Mortgage Loans have been assigned by the Mortgage Loan Seller to the Purchaser and by the Purchaser to the Trustee in accordance with this Agreement for the benefit of the Certificateholders by including (or deleting, in the case of Mortgage Loans which are repurchased in accordance with this Agreement) in such computer files (a) the code in the field which identifies the specific Trustee and (b) the code in the field “Pool Field” which identifies the series of the Certificates issued in connection with such Mortgage Loans. The Mortgage Loan Seller further agrees that it will not, and will not permit any Servicer or the Master Servicer to, and the Master Servicer agrees that it will not, alter the codes referenced in this paragraph with respect to any Mortgage Loan during the term of the Pooling and Servicing Agreement

unless and until such Mortgage Loan is repurchased in accordance with the terms of the Pooling and Servicing Agreement.

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

SECTION 5. Examination of Mortgage Files.

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

(b) Pursuant to the Pooling and Servicing Agreement, on the Closing Date the Custodian, on behalf of the Trustee, for the benefit of the Certificateholders, will acknowledge receipt of each Mortgage Loan, by delivery to the Mortgage Loan Seller, the Purchaser and the Trustee of an initial certification in the form attached as Exhibit One to the Custodial Agreement.

(c) Pursuant to the Pooling and Servicing Agreement, within 90 days of the Closing Date (or, with respect to any Substitute Mortgage Loan, within five business days after the receipt by the Trustee or Custodian thereof), the Trustee will review or shall cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will deliver to the Mortgage Loan Seller, the Purchaser and the Trustee an interim certification substantially in the form of Exhibit Two to the Custodial Agreement. If the Trustee or Custodian, as its agent, finds any document listed on Exhibit 1 not to have been executed or received, or to be unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in the Final Mortgage Loan Schedule or to appear defective on its face (a “Material Defect”), the Trustee or the Custodian, as its agent, shall promptly notify the Mortgage Loan Seller of such Material Defect. The Mortgage Loan Seller shall correct or cure any such Material Defect within 90 days from the date of notice from the Trustee or the Custodian, as its agent, of the Material Defect and if the Mortgage Loan Seller fails to correct or

cure such Material Defect within such period and such defect materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan, the Mortgage Loan Seller will, in accordance with the terms of the Pooling and Servicing Agreement, within 90 days of the date of notice, provide the Trustee with a Substitute Mortgage Loan (if within two years of the Closing Date) or purchase the related Mortgage Loan at the applicable Purchase Price; provided that, if such defect would cause the Mortgage Loan to be other than a “qualified mortgage” as defined in Section 860G(a)(3) of the Code, any such cure, repurchase or substitution must occur within 90 days from the date such breach was discovered; provided, however, that if such defect relates solely to the inability of the Mortgage Loan Seller to deliver the original Security Instrument or intervening assignments thereof, or a certified copy because the originals of such documents, or a certified copy, have not been returned by the applicable jurisdiction, the Mortgage Loan Seller shall not be required to purchase such Mortgage Loan if the Mortgage Loan Seller delivers such original documents or certified copy promptly upon receipt, but in no event later than 360 days after the Closing Date. The foregoing repurchase obligation shall not apply in the event that the Mortgage Loan Seller cannot deliver such original or copy of any document submitted for recording to the appropriate recording office in the applicable jurisdiction because such document has not been returned by such office; provided that the Mortgage Loan Seller shall instead deliver a recording receipt of such recording office or, if such receipt is not available, a certificate confirming that such documents have been accepted for recording, and delivery to the Trustee or the Custodian, as its agent, shall be effected by the Mortgage Loan Seller within thirty days of its receipt of the original recorded document.

(d) Pursuant to the Pooling and Servicing Agreement, within 180 days of the Closing Date (or, with respect to any Substitute Mortgage Loan, within five business days after the receipt by the Trustee or Custodian thereof) the Trustee will review or cause the Custodian to review items of the Mortgage Files as set forth on Exhibit 1 and will deliver to the Mortgage Loan Seller, the Purchaser and the Trustee a final certification substantially in the form of Exhibit Three to the Custodial Agreement. If the Trustee or Custodian, as its agent, finds a Material Defect, the Trustee or the Custodian, as its agent, shall promptly notify the Mortgage Loan Seller of such Material Defect. The Mortgage Loan Seller shall correct or cure any such Material Defect within 90 days from the date of notice from the Trustee or the Custodian, as its agent, of the Material Defect and if the Mortgage Loan Seller fails to correct or cure such Material Defect within such period and such defect materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan, the Mortgage Loan Seller will, in accordance with the terms of the Pooling and Servicing Agreement, within 90 days of the date of notice, provide the Trustee with a Substitute Mortgage Loan (if within two years of the Closing Date) or purchase the related Mortgage Loan at the applicable Purchase Price; provided that, if such defect would cause the Mortgage Loan to be other than a “qualified mortgage” as defined in Section 860G(a)(3) of the Code, any such cure, repurchase or substitution must occur within 90 days from the date such breach was discovered; provided, however, that if such defect relates solely to the inability of the Mortgage Loan Seller to deliver the original Security Instrument or intervening assignments thereof, or a certified copy because the originals of such documents, or a certified copy, have not been returned by the applicable jurisdiction, the Mortgage Loan Seller shall not be required to purchase such Mortgage Loan if the Mortgage Loan Seller delivers such original documents or certified copy promptly upon receipt, but in no event later than 360 days after the Closing Date. The foregoing repurchase obligation shall not apply in the event that the Mortgage Loan Seller cannot deliver such original or copy of any document submitted for

recording to the appropriate recording office in the applicable jurisdiction because such document has not been returned by such office; provided that the Mortgage Loan Seller shall instead deliver a recording receipt of such recording office or, if such receipt is not available, a certificate confirming that such documents have been accepted for recording, and delivery to the Trustee or the Custodian, as its agent, shall be effected by the Mortgage Loan Seller within thirty days of its receipt of the original recorded document.

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

SECTION 6. Recordation of Assignments of Mortgage.

(a) The Mortgage Loan Seller shall cause each assignment of the Security Instrument from the Mortgage Loan Seller 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 has been provided to the Trustee (with a copy to the Custodian) which states that the recordation of such assignment is not necessary 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 Mortgage Loan Seller and its successors and assigns; provided, however, notwithstanding the delivery of any such Opinion of Counsel, each assignment of Mortgage shall be submitted for recording by the Mortgage Loan Seller in the manner described above, at no expense to the Trust Fund or Trustee, upon the earliest to occur of (i) reasonable direction by the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Trust, (ii) the occurrence of an Event of Default, (iii) the occurrence of a bankruptcy, insolvency or foreclosure relating to the Mortgage Loan Seller and, (iv) the occurrence of a servicing transfer as described in Section 8.02 of the Pooling and Servicing Agreement.

While each such Mortgage or assignment is being recorded, if necessary, the Mortgage Loan Seller shall leave or cause to be left with the Trustee a certified copy of such Mortgage or assignment. All customary recording fees and reasonable expenses relating to the recordation of the assignments of mortgage to the Trustee or the Opinion of Counsel, as the case may be, shall be borne by the Mortgage Loan Seller.

(b) It is the express intent of the parties hereto that the conveyance of the Mortgage Loans by the Mortgage Loan Seller to the Purchaser, as contemplated by this Agreement be, and be treated as, a sale. It is, further, not the intention of the parties that such conveyance be deemed a pledge of the Mortgage Loans by the Mortgage Loan Seller to the Purchaser to secure a debt or other obligation of the Mortgage Loan Seller. However, in the

event that, notwithstanding the intent of the parties, the Mortgage Loans are held by a court of competent jurisdiction to continue to be property of the Mortgage Loan Seller, then (i) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the applicable Uniform Commercial Code; (ii) the transfer of the Mortgage Loans provided for herein shall be deemed to be a grant by the Mortgage Loan Seller to the Purchaser of a security interest in all of the Mortgage Loan Seller’s right, title and interest in and to the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, to the extent the Purchaser would otherwise be entitled to own such Mortgage Loans and proceeds pursuant to Section 4 hereof, including all amounts, other than investment earnings, from time to time held or invested in any accounts created pursuant to the Pooling and Servicing Agreement, whether in the form of cash, instruments, securities or other property; (iii) the possession by the Purchaser or the Trustee of Mortgage Notes and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be deemed to be “possession by the secured party” for purposes of perfecting the security interest pursuant to Section 9-313 (or comparable provision) of the applicable Uniform Commercial Code; and (iv) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Purchaser for the purpose of perfecting such security interest under applicable law. Any assignment of the interest of the Purchaser pursuant to any provision hereof or pursuant to the Pooling and Servicing Agreement shall also be deemed to be an assignment of any security interest created hereby. The Mortgage Loan Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be reasonably necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Pooling and Servicing Agreement.
