POOLING AND SERVICING AGREEMENT

This Pooling and Servicing Agreement is dated as of May 1, 2005 (the “Agreement”), among MERRILL LYNCH MORTGAGE INVESTORS, INC., as depositor (the “Depositor”), WELLS FARGO BANK, N.A., as master servicer (in such capacity, the “Master Servicer”) and as securities administrator (in such capacity, the “Securities Administrator”) and WACHOVIA BANK, NATIONAL ASSOCIATION, as trustee (the “Trustee”).

PRELIMINARY STATEMENT

The Depositor intends to sell mortgage pass-through certificates (collectively, the “Certificates”), to be issued hereunder in multiple classes, which in the aggregate will evidence the entire beneficial ownership interest in the Mortgage Loans (as defined herein). As provided herein, the Trustee will make, in accordance with Section 9.12, an election to treat the entire segregated pool of assets described in the definition of REMIC I (as defined herein), and subject to this Agreement, as a real estate mortgage investment conduit (a “REMIC”) for federal income tax purposes and such segregated pool of assets will be designated as “REMIC I.” The REMIC I Regular Interests will be the “regular interests” in REMIC I and the Class R-I Certificates will be the sole class of “residual interests” in REMIC I for purposes of the REMIC Provisions (as defined herein) under the federal income tax law. A segregated pool of assets consisting of the REMIC I Regular Interests will be designated as “REMIC II,” and the Trustee will make, in accordance with Section 9.12, a separate REMIC election with respect thereto. The REMIC II Regular Interests will be “regular interests” in REMIC II and the Class R-II Certificates will be the sole Class of “residual interests” in REMIC II for purposes of the REMIC Provisions. A segregated pool of assets consisting of the REMIC II Regular Interests will be designated as “REMIC III” and the REMIC Administrator will make a separate REMIC election with respect thereto. The Class I-A, Class II-A-1, Class II-A-2, Class II-A-IO, Class III-A, Class IV-A, Class M-1, Class M-2, Class M-3, Class B-1, Class B-2 and Class B-3 Certificates will be “regular interests” in REMIC III, and the Class R-III Certificates will be the sole class of “residual interests” therein for purposes of the REMIC Provisions (as defined herein) under federal income tax law.

The following table irrevocably sets forth the designation, the REMIC I Pass-Through Rate, the initial Uncertificated Principal Balance and, for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” for the REMIC I Regular Interest.

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

Accepted Master Servicing Practices : With respect to any Mortgage Loan, as applicable, either (x) those customary mortgage master servicing practices of prudent mortgage servicing institutions that master service mortgage loans of the same type and quality as such Mortgage Loan in the jurisdiction where the related Mortgaged Property is located, to the extent applicable to the Trustee or the Master Servicer (except in its capacity as successor to a Servicer), or (y) as provided in the applicable Servicing Agreement, to the extent applicable to any Servicer, but in no event below the standard set forth in clause (x).

Account : The Master Servicer Collection Account, Distribution Account and any Protected Account as the context may require.

Accrued Certificate Interest : With respect to each Class of Certificates, an amount equal to the interest accrued during the related Interest Accrual Period on the Class Certificate Balance or Notional Amount thereof at the then-applicable Pass-Through Rate. Accrued Certificate Interest on any Class of Certificates will be reduced by the amount of (i) Prepayment Interest Shortfalls (to the extent not offset by the related Servicer or Master Servicer with a payment of Compensating Interest as provided in Section 6.06), (ii) the interest portion of Excess Losses allocated to such Class of Certificates pursuant to Section 6.02 and (iii) any other interest shortfalls not covered by the subordination provided by the Class M Certificates and Class B Certificates, including shortfalls as a result of the Relief Act or similar legislation or regulations, with all such reductions allocated among all of the Certificates in proportion to their respective amounts of Accrued Certificate Interest payable on such Distribution Date which would have resulted absent such reductions.

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

Agreement : This Pooling and Servicing Agreement, including the exhibits hereto, and all amendments hereof and supplements hereto.

Applicable Credit Rating : For any long-term deposit or security, a credit rating of AAA in the case of Fitch and S&P or Aaa in the case of Moody’s. For any short-term deposit or security, a rating of F-1+ in the case of Fitch or A-l+ in the case of S&P or P-1 in the case of Moody’s.

Applicable Credit Support Percentage : With respect to any Class of Certificates, the sum of the related Class Subordination Percentages of such Class and all Classes of Subordinate Certificates which have a lower relative priority of payment than such Class.

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

Appraised Value : For any Mortgaged Property related to a Mortgage Loan other than any Washington Mutual Loan, the amount set forth as the appraised value of such Mortgaged Property in an appraisal made for the mortgage originator in connection with its origination of the related Mortgage Loan. With respect to any Washington Mutual Loan, for any Mortgaged Property or Cooperative Unit, as applicable, the lesser of (i) the value thereof as determined by an appraisal made for the originator of the Mortgage Loan at the time of origination of the Mortgage Loan by an appraiser who met the minimum requirements of Washington Mutual’s Underwriting Guidelines, and (ii) the purchase price paid for the related Mortgaged Property or Cooperative Unit, as applicable, by the Mortgagor with the proceeds of the Mortgage Loan, provided, however, in the case of a Refinanced Mortgage Loan, such value of the Mortgaged Property or Cooperative Unit, as applicable, is based solely upon the value determined by an appraisal made for the originator of such Refinanced Mortgage Loan at the time of origination of such Refinanced Mortgage Loan by an appraiser who met the minimum requirements under the Washington Mutual’s Underwriting Guidelines.

Assignment : An assignment of the Mortgage, notice of transfer or equivalent instrument, in recordable form, sufficient under the laws of the jurisdiction wherein the related Mortgaged Property is located to reflect of record the sale of the Mortgage Loan to the Trustee for the benefit of Certificateholders, which assignment, notice of transfer or equivalent instrument may be in the form of one or more blanket assignments covering Mortgages secured by Mortgaged Properties located in the same county, if permitted by law and accompanied by an Opinion of Counsel to that effect.

Assignment Agreements : The National City Assignment Agreement, the Countrywide Assignment Agreement, the PHH Assignment Agreement and the Washington Mutual Assignment Agreement, which are attached hereto as Exhibit I.

Assumed Final Distribution Date : For all Classes of Certificates, July 25, 2035, or if such day is not a Business Day, the next succeeding Business Day.

Available Funds : For any Distribution Date, the sum of the Group I Available Funds, Group II Available Funds, Group III Available Funds and the Group IV Available Funds.

Average Loss Severity : With respect to any period and each Loan Group, the fraction obtained by dividing (x) the aggregate amount of Realized Losses for the related Mortgage Loans for such period by (y) the number of related Mortgage Loans which had Realized Losses for such period.

Bankruptcy Code : The United States Bankruptcy Code, as amended as codified in 11 U.S.C. §§ 101-1330.

Bankruptcy Loss Coverage Amount : As of any date of determination prior to the first anniversary of the Cut-off Date, an amount equal to the excess, if any, of (A) $185,209 over (B) the aggregate amount of Bankruptcy Losses allocated solely to one or more specific Classes of Certificates in accordance with Section 6.02. As of any date of determination on or after the first anniversary of the Cut-off Date, an amount equal to the excess, if any, of (1) the lesser of (a) the Bankruptcy Loss Coverage Amount calculated as of the close of business on the Business Day immediately preceding the most recent anniversary of the Cut-off Date coinciding with or preceding such date of determination (or, if such date of determination is an anniversary of the Cut-off Date, the Business Day immediately preceding such date of determination) (for purposes of this definition, the “Relevant Anniversary”) and (b) the greater of

(A) the greater of (i) 0.0006 times the aggregate principal balance of all the Mortgage Loans in the Mortgage Pool as of the Relevant Anniversary having a Loan-to-Value Ratio at origination which exceeds 75% and (ii) $100,000; and (B) the greater of (i) the product of (x) an amount equal to the largest difference in the related Monthly Payment for any Non-Primary Residence Loan remaining in the Mortgage Pool which had an original Loan-to-Value Ratio greater than 80% that would result if the Net Mortgage Rate thereof was equal to the greater of (I) 5% or (II) the weighted average (based on the principal balance of the Mortgage Loans as of the Relevant Anniversary) of the Net Mortgage Rates of all Mortgage Loans as of the Relevant Anniversary less 1.25% per annum, (y) a number equal to the weighted average remaining term to maturity, in months, of all Mortgage Loans with a Loan-to-Value Ratio of greater than 80% remaining in the Mortgage Pool as of the Relevant Anniversary, and (z) one plus the quotient of the number of all Non-Primary Residence Loans with a Loan-to-Value Ratio of greater than 80% remaining in the Mortgage Pool divided by the total number of outstanding Mortgage Loans in the Mortgage Pool as of the Relevant Anniversary, and (ii) $50,000,

over (2) the aggregate amount of Bankruptcy Losses allocated solely to one or more specific Classes of Certificates in accordance with Section 6.02 since the Relevant Anniversary.

The Bankruptcy Loss Coverage Amount may be further reduced by the Depositor (including accelerating the manner in which such coverage is reduced) provided that prior to any such reduction, the Depositor shall (i) obtain written confirmation from each Rating Agency that such reduction shall not reduce the rating assigned to any Class of Certificates by such Rating Agency below the lower of the then-current rating or the rating assigned to such Certificates as of the Closing Date by such Rating Agency and (ii) provide a copy of such written confirmation to the Trustee.

On the Closing Date, the Certificates (other than the Class R Certificates and the Private Certificates) shall be Book-Entry Certificates.

Notwithstanding the foregoing, if the Depositor 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 Fund in accordance with Section 9.05.

If any original Mortgage Note referred to in Section 2.01(b)(I)(i) or 2.01(b)(II)(i) above cannot be located, the obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon delivery to the Trustee of a photocopy of such Mortgage Note, if available, with a lost note affidavit.

Section 2.02

Acceptance of Mortgage Loans by Trustee .

(a) The Trustee acknowledges the sale, transfer and assignment of the Trust 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, or the Custodian on its behalf, holds the documents (or certified copies thereof) delivered to it 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 or before 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 on the Closing Date an Initial Certification. In conducting such review, the Trustee or Custodian will certify as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan specifically identified in the exception report annexed thereto as not being covered by such certification), (i) all documents constituting part of such Mortgage File (other than such documents described in Section 2.01(b)(I)(iii)) required to be delivered to it pursuant to this Agreement are in its possession, provided that with respect to the documents described in Section 2.01(b)(I)(v), (vi), (viii) and (ix) and 2.01(b)(II)(viii) and (ix) to the extent the Trustee or the Custodian on its behalf has actual knowledge that such documents exist, (ii) such documents have been reviewed by it and are not torn, mutilated, defaced or otherwise altered (except if initialed by the obligor) and appear to relate on their face to such Mortgage Loan, (iii) based on its examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule corresponding to the loan number for the Mortgage Loan, the Mortgagor's name, including the street address but excluding the zip code, the Mortgage Interest Rate and the original principal balance of the Mortgage Loan accurately reflects information set forth in the Mortgage File and (iv) with respect to Mortgage Loans with a Mortgage Interest Rate subject to adjustment, the gross margin, the lifetime cap and the periodic cap for such Mortgage Loan. 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. Notwithstanding anything to the contrary in this Agreement, it is herein acknowledged that, in conducting such review, the Trustee or the Custodian on its behalf is under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine whether they are genuine, enforceable, or appropriate for the represented purpose or whether they have actually been recorded or that they are other than what they purport to be on their face, or to determine whether any Person executing any documents is authorized to do so or whether any signature is genuine. If the Trustee or the Custodian, as its agent, finds any document constituting part of the Mortgage File not to have been executed or received, or to be unrelated to the Mortgage Loans identified in Exhibit B or to appear to be defective on its face, 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 pursuant to the Mortgage Loan Purchase Agreement, within 90 days from the Trustee's or the Custodian's notification, to purchase such Mortgage Loan at the 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 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, 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 a Final Certification. In conducting such review, the Trustee or the Custodian, as its agent, will certify as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan specifically identified in the exception report annexed thereto as not being covered by such certification), that (i) all documents constituting part of such Mortgage File (other than such documents described in Section 2.01(b)(I)(v) and (ix)) required to be delivered to it pursuant to this Agreement are in its possession, provided that with respect to the documents described in Section 2.01(b)(I)(v), (vi), (viii) and (ix) and 2.01(b)(II)(viii) and (ix) to the extent the Trustee or the Custodian on its behalf has actual knowledge that such documents exist, (ii) such documents have been reviewed by it and are not torn, mutilated, defaced or

otherwise altered (except if initialed by the obligor) and appear regular on their face and relate to such Mortgage Loan, (iii) based on its examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule corresponding to the loan number for the Mortgage Loan, the Mortgagor's name, including the street address but excluding the zip code, the Mortgage Interest Rate and the original principal balance of the Mortgage Loan accurately reflects information set forth in the Mortgage File. 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. Notwithstanding anything to the contrary in this Agreement, it is herein acknowledged that, in conducting such review, the Trustee or the Custodian on its behalf is under no duty or obligation (i) to inspect, review or examine any such documents, instruments, certificates or other papers to determine whether they are genuine, enforceable, or appropriate for the represented purpose or whether they have actually been recorded or that they are other than what they purport to be on their face, or to determine whether any Person executing any documents is authorized to do so or whether any signature is genuine. If the Trustee or the Custodian, as its agent, finds any document constituting part of the Mortgage File not to have been executed or received, or to be unrelated to the Mortgage Loans identified in Exhibit B or to appear to be defective on its face, 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 90 days from the date of notice from the Trustee of the defect and if the Seller is unable to cure such defect within such period, and if such defect materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan, the Trustee shall enforce the Seller's obligation under the Mortgage Loan Purchase Agreement to purchase such Mortgage Loan at the Purchase Price, 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.

(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 Purchase Price for deposit in the Master Servicer Collection Account and the Seller shall provide to the Trustee written notification detailing the components of the Purchase Price. Upon deposit of the Purchase Price in the Master Servicer Collection Account, the Depositor shall notify the Trustee and the Custodian and the Trustee or the Custodian, as its agent (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, 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 Purchase Price in available funds is received by the Trustee. The Trustee shall amend the Mortgage Loan Schedule, which was previously delivered to it by 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 any Mortgage Loan as to which such a defect in a constituent document exists shall be the sole remedy respecting such defect available to the Certificateholders or to the Trustee on their behalf.

Section 2.03

Assignment of Interest in the Mortgage Loan Purchase Agreement .

(a) The Depositor hereby assigns to the Trustee, on behalf of the Certificateholders, all of its right, title and interest in the Mortgage Loan Purchase Agreement, including but not limited to 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. With respect to the representations and warranties described in the Mortgage Loan Purchase Agreement which are made to the best of the Seller's knowledge, if it is discovered by any of the Depositor, the Seller or the Trustee that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan, then notwithstanding the Seller's lack of knowledge with respect to the substance of such representation and warranty, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

(b) If the Depositor, the Master Servicer, 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 Purchase Price, any excess of the Purchase Price over the Net Liquidation Proceeds received upon such sale. (If the Net Liquidation Proceeds exceed the Purchase 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 Purchase Price to the Master Servicer for deposit in the Master Servicer Collection Account and written notification detailing the components of such Purchase Price. The Depositor shall notify the Trustee and submit to the Trustee or the Custodian, as its agent, a Request for Release, and the Trustee shall release, or the Trustee shall cause the Custodian to release, to the Seller the related Mortgage File and the Trustee shall execute and deliver all instruments of transfer or assignment furnished to it by the Seller, without recourse, 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 Purchase Price in available funds is received by the Trustee. The Trustee or the Master Servicer shall amend the Mortgage Loan Schedule to reflect such repurchase and shall promptly notify the Master Servicer 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 Purchase 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 the Mortgage Loan Purchase Agreement or this Agreement, as applicable; provided, however, that substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, in lieu of purchase shall not be permitted after the termination of the two-year period beginning on the Startup Day; provided, further, that if the breach would cause the Mortgage Loan to be other than a “qualified mortgage” as defined in Section 860G(a)(3) of the Code, any such cure or substitution must occur within 90 days from the date the breach was discovered. The Trustee or the Custodian, as its agent, shall examine the Mortgage File for any Substitute Mortgage Loan in the manner set forth in Section 2.02(a) and the Trustee or the Custodian, as its agent, shall notify the Seller, in writing, within five Business Days after receipt, whether or not the documents relating to the Substitute Mortgage Loan satisfy the requirements of the fourth sentence of Subsection 2.02(a). Within two Business Days after such notification, the Seller shall provide to the Trustee for deposit in the Distribution Account the amount, if any, by which the Outstanding Principal Balance as of the next preceding Due Date of the Mortgage Loan for which substitution is being made, after giving effect to 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 Purchase Price for the purchase of a Mortgage Loan by the Seller. After such notification to the Seller and, if any such excess exists, upon receipt of such deposit, the Trustee shall accept such Substitute Mortgage Loan which shall thereafter be deemed to be a Mortgage Loan hereunder. In the event of such a substitution, accrued interest on the Substitute Mortgage Loan for the month in which the substitution occurs and any Principal Prepayments made thereon during such month shall be the property of the Trust Fund and accrued interest for such month on the Mortgage Loan for which the substitution is made and any Principal Prepayments made thereon during such month shall be the property of the Seller. The Scheduled Principal on a Substitute Mortgage Loan due on the Due Date in the month of substitution shall be the property of the Seller and the Scheduled Principal on the Mortgage Loan for which the substitution is made due on such Due Date shall be the property of the Trust Fund. Upon acceptance of the Substitute Mortgage Loan (and delivery to the Trustee or Custodian of a Request for Release for such Mortgage Loan), 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, in form as provided to it as are necessary to vest in the Seller title to and rights under any Mortgage Loan released pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable. The Seller shall deliver the documents related to the Substitute

Mortgage Loan in accordance with the provisions of the Mortgage Loan Purchase Agreement or 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 .

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 the 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 to the Protected Account pursuant to the applicable Servicing Agreements.

If the Master Servicer and the Securities Administrator are the same entity, then at any time the Master Servicer is terminated as Master Servicer, the Securities Administrator shall likewise be removed as securities administrator.

The Trustee shall furnish the Servicers and the Master Servicer with any limited 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 shall have no liability with respect to the use of any such limited power of attorney.

The Trustee or the Custodian shall provide access to the records and documentation in possession of the Trustee or 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 Trustee or the Custodian; provided, however, that, unless otherwise required by law, the Trustee or the Custodian 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 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 upon request 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 3.03 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 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 in to a new Servicing Agreement with a successor Servicer selected by the Master Servicer; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to such successor Servicer. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Servicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense subject to Section 3.03(c), provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action.

(c) To the extent that the costs and expenses of the Master Servicer related to any termination of a Servicer, appointment of a successor Servicer or the transfer and assumption of servicing by the Master Servicer with respect to any Servicing Agreement (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the Servicer as a result of an event of default by such Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including 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 service 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 pursuant to Section 4.03(b).

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

(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, would cause REMIC I, REMIC II or REMIC III 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 will not would cause REMIC I, REMIC II or REMIC III to fail to qualify as a REMIC or result in the imposition of a tax upon

REMIC I, REMIC II or REMIC III, as the case may be. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any limited 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 or the Master Servicer will, if required under the applicable Servicing Agreement, 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 no later than five Business Days (or, to the extent that the applicable Servicer notifies the Seller that a document is not in the Servicer’s possession as part of the Servicing File which is needed for purposes of the Servicer complying with any applicable law, within such shorter period as may be necessary to enable the Servicer to comply with such law), 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 inc
