This Pooling and Servicing Agreement, effective as of April 1, 2005, among RESIDENTIAL ASSET SECURITIES CORPORATION, as the depositor (together with its permitted successors and assigns, the “Depositor”), RESIDENTIAL FUNDING CORPORATION, as master servicer (together with its permitted successors and assigns, the “Master Servicer”), and U.S. BANK NATIONAL ASSOCIATION, a banking association organized under the laws of the United States, as trustee (together with its permitted successors and assigns, the “Trustee”).

PRELIMINARY STATEMENT:

The Depositor intends to sell mortgage asset-backed pass-through certificates (collectively, the “Certificates”), to be issued hereunder in sixteen Classes, which in the aggregate will evidence the entire beneficial ownership interest in the Mortgage Loans (as defined herein) and certain other related assets.

REMIC I

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

(1) The Class A, Class M and Class B Certificates will represent ownership of REMIC II Regular Interests together with certain rights to payments to be made from amounts received under the related Hedge Agreement which will be deemed made for federal income tax purposes outside of REMIC II by the holder of the Class SB Certificates as the owner of the Hedge Agreements.

(2) The REMIC II Regular Interests ownership of which is represented by the Class A, Class M and Class B Certificates, will accrue interest at a per annum rate equal to the lesser of (i) LIBOR plus the applicable Margin and (ii) the REMIC Net WAC Cap Rate and the provisions for the payment of Basis Risk Shortfalls herein, which payments will not be part of the entitlement of the REMIC II Regular Interests related to such Certificates. (3) The Class A, Class M and Class B Certificates will also entitle their holders to certain payments from the Holder of the Class SB Certificates from amounts to which the related REMIC II Regular Interest is entitled and from amounts received under the Hedge Agreements, which will not be a part of their ownership of the REMIC II Regular Interests.

(4) The Class SB Certificates will accrue interest as described in the definition of Accrued Certificate Interest. The Class SB Certificates will not accrue interest on their Certificate Principal Balance. The Class SB Certificates will represent ownership of two REMIC II Regular Interests, a principal only regular interest designated REMIC II Regular Interest SB-PO and an interest only regular interest designated REMIC II Regular Interest SB-IO, which will be entitled to distributions as set forth herein. The rights of the Holder of the Class SB Certificates to payments from the Hedge Agreements shall be outside and apart from its rights under the REMIC II Regular Interests SB-IO and SB-PO.

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

ARTICLE I

DEFINITIONS

Section 1.01. Definitions.

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

Accrued Certificate Interest: With respect to each Distribution Date and each Class of Class A Certificates, Class M Certificates and Class B Certificates, interest accrued during the related Interest Accrual Period on the Certificate Principal Balance thereof immediately prior to such Distribution Date at the related Pass-Through Rate for that Distribution Date.

The amount of Accrued Certificate Interest on each Class of Certificates shall be reduced by the amount of Prepayment Interest Shortfalls on the related Mortgage Loans during the prior calendar month to the extent not covered by Compensating Interest pursuant to Section 3.16, and by Relief Act Shortfalls on the related Mortgage Loans during the related Due Period. All such reductions with respect to the Mortgage Loans will be allocated among the Certificates in proportion to the amounts of Accrued Certificate Interest payable on such Certificates on such Distribution Date absent such reductions.

Accrued Certificate Interest on each Class of Class A Certificates, Class M Certificates and Class B Certificates for any Distribution Date shall also be reduced by any interest shortfalls resulting from the failure of the Hedge Agreements Provider to make the related required Hedge Payment for such Distribution Date, with all such reductions on the Class A Certificates allocated to the Class A Certificates on a pro rata basis, based on the portion of the Class A Hedge Payment each such Class was entitled to, but did not receive, on such Distribution Date and all such reductions on the Class M Certificates and Class B Certificates allocated to the Class M Certificates and Class B Certificates on a pro rata basis, based on the portion of the Subordinate Hedge Payment each such Class was entitled to, but did not receive, on such Distribution Date.

Accrued Certificate Interest for any Distribution Date shall further be reduced by the interest portion of Realized Losses allocated to any Class of Certificates pursuant to Section 4.05.

Accrued Certificate Interest shall accrue on the basis of a 360-day year and the actual number of days in the related Interest Accrual Period.

With respect to each Distribution Date and the Class SB Certificates, interest accrued during the preceding Interest Accrual Period at the related Pass-Through Rate on the Notional Amount as specified in the definition of Pass-Through Rate, immediately prior to such Distribution Date, reduced by any interest shortfalls with respect to the Mortgage Loans, including Prepayment Interest Shortfalls to the extent not covered by Compensating Interest pursuant to Section 3.16 or by Excess Cash Flow pursuant to Section 4.02(c)(v) and (vi). Accrued Certificate Interest on the Class SB Certificates shall accrue on the basis of a 360-day year and the actual number of days in the related Interest Accrual Period.

Adjusted Mortgage Rate: With respect to any Mortgage Loan and any date of determination, the Mortgage Rate borne by the related Mortgage Note, less the rate at which the related Subservicing Fee accrues.

Adjustment Date: With respect to each adjustable-rate Mortgage Loan, each date set forth in the related Mortgage Note on which an adjustment to the interest rate on such Mortgage Loan becomes effective.

Advance: With respect to any Mortgage Loan, any advance made by the Master Servicer, pursuant to Section 4.04.

Affiliate: With respect to any Person, any other Person controlling, controlled by or under common control with such first Person. For purposes of this definition, “control” means the power to direct the management and policies of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing.

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

Amount Held for Future Distribution: With respect to any Distribution Date, the total of the amounts held in the Custodial Account at the close of business on the preceding Determination Date on account of (i) Liquidation Proceeds, Subsequent Recoveries, Insurance Proceeds, REO Proceeds, Principal Prepayments, Mortgage Loan purchases made pursuant to Section 2.02, 2.03, 2.04 or 4.07 and Mortgage Loan substitutions made pursuant to Section 2.03 or 2.04 received or made in the month of such Distribution Date (other than such Liquidation Proceeds, Subsequent Recoveries, Insurance Proceeds, REO Proceeds and purchases of Mortgage Loans that the Master Servicer has deemed to have been received in the preceding month in accordance with Section 3.07(b)) and (ii) payments which represent early receipt of scheduled payments of principal and interest due on a date or dates subsequent to the Due Date in the related Due Period.

Appraised Value: With respect to any Mortgaged Property, the lesser of (i) the appraised value of such Mortgaged Property based upon the appraisal made at the time of the origination of the related Mortgage Loan, and (ii) the sales price of the Mortgaged Property at such time of origination, except in the case of a Mortgaged Property securing a refinanced or modified Mortgage Loan as to which it is either the appraised value based upon the appraisal made at the time of origination of the loan which was refinanced or modified or the appraised value determined in an appraisal at the time of refinancing or modification, as the case may be.

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

Y₁ = the aggregate principal balance of the REMIC I Regular Interest LT1 after distributions on the prior Distribution Date.

Y₂ = the principal balance of the REMIC I Regular Interest LT2 after distributions on the prior Distribution Date.

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

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

ÄY₁ = the REMIC I Regular Interest LT1 Principal Reduction Amount.

ÄY₂ = the REMIC I Regular Interest LT2 Principal Reduction Amount.

ÄY₃ = the REMIC I Regular Interest LT3 Principal Reduction Amount.

ÄY₄ = the REMIC I Regular Interest LT4 Principal Reduction Amount.

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

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

ÄP = P₀ — P₁ = the aggregate of the REMIC I Regular Interests LT1, LT2, LT3 and LT4 Principal Reduction Amounts.

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

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

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

á = (Y₂ + Y₃)/P₀. The initial value of á on the Closing Date for use on the first Distribution Date shall be 0.0001.

ã₀ = the lesser of (A) the sum for all Classes of Certificates, other than the Class SB Certificates, of the product for each Class of (i) the monthly interest rate (as limited by the REMIC Net WAC Rate, if applicable) for such Class applicable for distributions to be made on such Distribution Date and (ii) the aggregate Certificate Principal Balance for such Class after distributions and the allocation of Realized Losses on the prior Distribution Date and (B) R₀*P₀.

ã₁ = the lesser of (A) the sum for all Classes of Certificates, other than the Class SB Certificates, of the product for each Class of (i) the monthly interest rate (as limited by the REMIC Net WAC Cap Rate, if applicable) for such Class applicable for distributions to be made on the next succeeding Distribution Date and (ii) the aggregate Certificate Principal Balance for such Class after distributions and the allocation of Realized Losses to be made on such Distribution Date and (B) R₁*P₁.

Then, based on the foregoing definitions:

AY1 = AP - AY2 - AY3 - AY4;

ÄY₂ = (á/2){( ã₀R₁ — ã₁R₀)/R₀R₁};

AY3 = aAP - AY2; and

ÄY₄ = ÄY₃.

if both AY2 and AY3, as so determined, are non-negative numbers. Otherwise:

(1) If ÄY₂, as so determined, is negative, then

ÄY₂ = 0;

ÄY₃ = á{ã₁R₀P₀ — ã₀R₁P₁}/{ã₁R₀};

ÄY₄ = ÄY₃; and

ÄY₁ = ÄP — ÄY₂ — ÄY₃ — ÄY₄.

(2) If ÄY₃, as so determined, is negative, then

ÄY₃ = 0;

ÄY₂ = á{ã₁R₀P₀ — ã₀R₁P₁}/{2R₁R₀P₁ — ã₁R₀};

ÄY₄ = ÄY₃; and

ÄY₁ = ÄP — ÄY₂ — ÄY₃ — ÄY₄.

Section 1.02. Determination of LIBOR.

LIBOR applicable to the calculation of the Pass-Through Rate on the LIBOR Certificates for any Interest Accrual Period will be determined as of each LIBOR Rate Adjustment Date. On each LIBOR Rate Adjustment Date, or if such LIBOR Rate Adjustment Date is not a Business Day, then on the next succeeding Business Day, LIBOR shall be established by the Trustee and, as to any Interest Accrual Period, will equal the rate for one month United States dollar deposits that appears on the Telerate Screen Page 3750 as of 11:00 a.m., London time, on such LIBOR Rate Adjustment Date. “Telerate Screen Page 3750” means the display designated as page 3750 on the Bridge Telerate Service (or such other page as may replace page 3750 on that service for the purpose of displaying London interbank offered rates of major banks). If such rate does not appear on such page (or such other page as may replace that page on that service, or if such service is no longer offered, LIBOR shall be so established by use of such other service for displaying LIBOR or comparable rates as may be selected by the Trustee after consultation with the Master Servicer), the rate will be the Reference Bank Rate. The “Reference Bank Rate” will be determined on the basis of the rates at which deposits in U.S. Dollars are offered by the reference banks (which shall be any three major banks that are engaged in transactions in the London interbank market, selected by the Trustee after consultation with the Master Servicer) as of 11:00 a.m., London time, on the LIBOR Rate Adjustment Date to prime banks in the London interbank market for a period of one month in amounts approximately equal to the aggregate Certificate Principal Balance of the LIBOR Certificates then outstanding. The Trustee shall request the principal London office of each of the reference banks to provide a quotation of its rate. If at least two such quotations are provided, the rate will be the arithmetic mean of the quotations rounded up to the next multiple of 1/16%. If on such date fewer than two quotations are provided as requested, the rate will be the arithmetic mean of the rates quoted by one or more major banks in New York City, selected by the Trustee after consultation with the Master Servicer, as of 11:00 a.m., New York City time, on such date for loans in U.S. Dollars to leading European banks for a period of one month in amounts approximately equal to the aggregate Certificate Principal Balance of the LIBOR Certificates then outstanding. If no such quotations can be obtained, the rate will be LIBOR for the prior Distribution Date; provided however, if, under the priorities described above, LIBOR for a Distribution Date would be based on LIBOR for the previous Distribution Date for the third consecutive Distribution Date, the Trustee, shall select an alternative comparable index (over which the Trustee has no control), used for determining one-month Eurodollar lending rates that is calculated and published (or otherwise made available) by an independent party. The establishment of LIBOR by the Trustee on any LIBOR Rate Adjustment Date and the Trustee’s subsequent calculation of the Pass-Through Rates applicable to the LIBOR Certificates for the relevant Interest Accrual Period, in the absence of manifest error, will be final and binding. Promptly following each LIBOR Rate Adjustment Date the Trustee shall supply the Master Servicer with the results of its determination of LIBOR on such date. Furthermore, the Trustee shall supply to any Certificateholder so requesting by calling 1-800-934-6802 the Pass-Through Rate on the LIBOR Certificates for the current and the immediately preceding Interest Accrual Period.

(ii) The original Mortgage, noting the presence of the MIN of the Mortgage Loan and language indicating that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM Loan, with evidence of recording indicated thereon or, if the original Mortgage has not yet been returned from the public recording office, a copy of the original Mortgage with evidence of recording indicated thereon;

(iii) Unless the Mortgage Loan is registered on the MERS® System, the assignment (which may be included in one or more blanket assignments if permitted by applicable law) of the Mortgage to the Trustee with evidence of recording indicated thereon or a copy of such assignment with evidence of recording indicated thereon;

(iv) The original recorded assignment or assignments of the Mortgage showing an unbroken chain of title from the originator to the Person assigning it to the Trustee (or to MERS, if the Mortgage Loan is registered on the MERS® System and noting the presence of a MIN) with evidence of recordation noted thereon or attached thereto, or a copy of such assignment or assignments of the Mortgage with evidence of recording indicated thereon; and

(v) The original of each modification, assumption agreement or preferred loan agreement, if any, relating to such Mortgage Loan, or a copy of each modification, assumption agreement or preferred loan agreement.

The Depositor may, in lieu of delivering the original of the documents set forth in Section 2.01(b)(ii), (iii), (iv) and (v) (or copies thereof as permitted by Section 2.01(b)) to the Trustee or the Custodian or Custodians, deliver such documents to the Master Servicer, and the Master Servicer shall hold such documents in trust for the use and benefit of all present and future Certificateholders until such time as is set forth in the next sentence.

The Depositor shall promptly cause to be recorded in the appropriate public office for real property records the Assignment referred to in clause (iii) of Section 2.01(b), except (a) in states where, in the opinion of counsel acceptable to the Master Servicer, such recording is not required to protect the Trustee’s interests in the Mortgage Loan or (b) if MERS is identified on the Mortgage or on a properly recorded assignment of the Mortgage, as applicable, as the mortgagee of record solely as nominee for Residential Funding and its successors and assigns. If any Assignment is lost or returned unrecorded to the Depositor because of any defect therein, the Depositor shall prepare a substitute Assignment or cure such defect, as the case may be, and cause such Assignment to be recorded in accordance with this paragraph.

In connection with the assignment of any Mortgage Loan registered on the MERS® System, the Depositor further agrees that it will cause, at the Depositor’s own expense, within 30 Business Days after the Closing Date, the MERS® System to indicate that such Mortgage Loans have been assigned by the Depositor 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 Depositor further agrees that it will not, and will not permit 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 this Agreement unless and until such Mortgage Loan is repurchased in accordance with the terms of this Agreement.

(d) It is intended that the conveyances by the Depositor to the Trustee of the Mortgage Loans as provided for in this Section 2.01 and the Uncertificated Regular Interests be construed as a sale by the Depositor to the Trustee of the Mortgage Loans and the Uncertificated Regular Interests for the benefit of the Certificateholders. Further, it is not intended that any such conveyance be deemed to be a pledge of the Mortgage Loans and the Uncertificated Regular Interests by the Depositor to the Trustee to secure a debt or other obligation of the Depositor. Nonetheless, (a) this Agreement is intended to be and hereby is a security agreement within the meaning of Articles 8 and 9 of the New York Uniform Commercial Code and the Uniform Commercial Code of any other applicable jurisdiction; (b) the conveyances provided for in this Section 2.01 shall be deemed to be (1) a grant by the Depositor to the Trustee of a security interest in all of the Depositor’s right (including the power to convey title thereto), title and interest, whether now owned or hereafter acquired, in and to (A) the Mortgage Loans, including the related Mortgage Note, the Mortgage, any insurance policies and all other documents in the related Mortgage File, (B) all amounts payable pursuant to the Mortgage Loans in accordance with the terms thereof, (C) any Uncertificated Regular Interests and any and all general intangibles, payment intangibles, accounts, chattel paper, instruments, documents, money, deposit accounts, certificates of deposit, goods, letters of credit, advices of credit and investment property and other property of whatever kind or description now existing or hereafter acquired consisting of, arising from or relating to any of the foregoing, and (D) all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, including without limitation all amounts from time to time held or invested in the Certificate Account or the Custodial Account, whether in the form of cash, instruments, securities or other property and (2) an assignment by the Depositor to the Trustee of any security interest in any and all of Residential Funding’s right (including the power to convey title thereto), title and interest, whether now owned or hereafter acquired, in and to the property described in the foregoing clauses (1)(A), (B), (C) and (D) granted by Residential Funding to the Depositor pursuant to the Assignment Agreement; (c) the possession by the Trustee, the Custodian or any other agent of the Trustee of Mortgage Notes or such other items of property as constitute instruments, money, payment intangibles, negotiable documents, goods, deposit accounts, letters of credit, advices of credit, investment property, certificated securities or chattel paper shall be deemed to be “possession by the secured party,” or possession by a purchaser or a person designated by such secured party, for purposes of perfecting the security interest pursuant to the Minnesota Uniform Commercial Code and the Uniform Commercial Code of any other applicable jurisdiction as in effect (including, without limitation, Sections 8-106, 9-313 and 9-106 thereof); and (d) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, securities intermediaries, bailees or agents of, or persons holding for, (as applicable) the Trustee for the purpose of perfecting such security interest under applicable law.

The Depositor and, at the Depositor’s direction, Residential Funding and the Trustee shall, to the extent consistent with this Agreement, take such reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the Uncertificated Regular Interests and the other property described above, 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 this Agreement. Without limiting the generality of the foregoing, the Depositor shall prepare and deliver to the Trustee not less than 15 days prior to any filing date and, the Trustee shall forward for filing, or shall cause to be forwarded for filing, at the expense of the Depositor, all filings necessary to maintain the effectiveness of any original filings necessary under the Uniform Commercial Code as in effect in any jurisdiction to perfect the Trustee’s security interest in or lien on the Mortgage Loans and the Uncertificated Regular Interests, as evidenced by an Officers Certificate of the Depositor, including without limitation (x) continuation statements, and (y) such other statements as may be occasioned by (1) any change of name of Residential Funding, the Depositor or the Trustee (such preparation and filing shall be at the expense of the Trustee, if occasioned by a change in the Trustee’s name), (2) any change of location of the place of business or the chief executive office of Residential Funding or the Depositor, (3) any transfer of any interest of Residential Funding or the Depositor in any Mortgage Loan or (4) any transfer of any interest of Residential Funding or the Depositor in any Uncertificated Regular Interests.

The Trustee acknowledges receipt (or, with respect to Mortgage Loans subject to a Custodial Agreement, and based solely upon a receipt or certification executed by the Custodian, receipt by the respective Custodian as the duly appointed agent of the Trustee) of the documents referred to in Section 2.01(b)(i) above (except that for purposes of such acknowledgement only, a Mortgage Note may be endorsed in blank and an Assignment of Mortgage may be in blank) and declares that it, or a Custodian as its agent, holds and will hold such documents and the other documents constituting a part of the Mortgage Files delivered to it, or a Custodian as its agent, in trust for the use and benefit of all present and future Certificateholders.

Upon delivery of the Mortgage Files by the Depositor or the Master Servicer, the Trustee shall acknowledge receipt (or, with respect to Mortgage Loans subject to a Custodial Agreement, and based solely upon a receipt or certification executed by the Custodian, receipt by the respective Custodian as the duly appointed agent of the Trustee) of the documents referred to in Section 2.01(b) above.

If the Custodian, as the Trustee’s agent, finds any document or documents constituting a part of a Mortgage File to be missing or defective, upon receipt of notification from the Custodian as specified in the succeeding sentence, the Trustee shall promptly so notify or cause the Custodian to notify the Master Servicer and the Depositor. Pursuant to Section 2.3 of the Custodial Agreement, the Custodian will notify the Master Servicer, the Depositor and the Trustee of any such omission or defect found by it in respect of any Mortgage File held by it in respect of the items received by it pursuant to the Custodial Agreement. If such omission or defect materially and adversely affects the interests in the related Mortgage Loan of the Certificateholders, the Master Servicer shall promptly notify the related Subservicer or Seller of such omission or defect and request that such Subservicer or Seller correct or cure such omission or defect within 60 days from the date the Master Servicer was notified of such omission or defect and, if such Subservicer or Seller does not correct or cure such omission or defect within such period, that such Subservicer or Seller purchase such Mortgage Loan from the Trust Fund at its Purchase Price, in either case within 90 days from the date the Master Servicer was notified of such omission or defect; provided that if the omission or 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. The Purchase Price for any such Mortgage Loan shall be deposited or caused to be deposited by the Master Servicer in the Custodial Account maintained by it pursuant to Section 3.07 and, upon receipt by the Trustee of written notification of such deposit signed by a Servicing Officer, the Trustee or any Custodian, as the case may be, shall release to the Master Servicer the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment prepared by the Master Servicer, in each case without recourse, as shall be necessary to vest in the Subservicer or Seller or its designee, as the case may be, any Mortgage Loan released pursuant hereto and thereafter such Mortgage Loan shall not be part of the Trust Fund. In furtherance of the foregoing and Section 2.04, if the Subservicer or Seller or Residential Funding that repurchases the Mortgage Loan is not a member of MERS and the Mortgage is registered on the MERS® System, the Master Servicer, at its own expense and without any right of reimbursement, shall cause MERS to execute and deliver an assignment of the Mortgage in recordable form to transfer the Mortgage from MERS to such Subservicer or Seller or Residential Funding and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and regulations. It is understood and agreed that the obligation of the Subservicer or Seller, to so cure or purchase any Mortgage Loan as to which a material and adverse defect in or omission of a constituent document exists shall constitute the sole remedy respecting such defect or omission available to Certificateholders or the Trustee on behalf of Certificateholders.

Section 2.03. Representations, Warranties and Covenants of the Master Servicer and the Depositor.

(a) The Master Servicer hereby represents and warrants to the Trustee for the benefit of the Certificateholders that:

(i) The Master Servicer is a corporation duly organized, validly existing and in good standing under the laws governing its creation and existence and is or will be in compliance with the laws of each state in which any Mortgaged Property is located to the extent necessary to ensure the enforceability of each Mortgage Loan in accordance with the terms of this Agreement;

(ii) The execution and delivery of this Agreement by the Master Servicer and its performance and compliance with the terms of this Agreement will not violate the Master Servicer’s Certificate of Incorporation or Bylaws or constitute a material default (or an event which, with notice or lapse of time, or both, would constitute a material default) under, or result in the material breach of, any material contract, agreement or other instrument to which the Master Servicer is a party or which may be applicable to the Master Servicer or any of its assets;

(iii) This Agreement, assuming due authorization, execution and delivery by the Trustee and the Depositor, constitutes a valid, legal and binding obligation of the Master Servicer, enforceable against it in accordance with the terms hereof subject to applicable bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforcement of creditors’ rights generally and to general principles of equity, regardless of whether such enforcement is considered in a proceeding in equity or at law;

(iv) The Master Servicer is not in default with respect to any order or decree of any court or any order, regulation or demand of any federal, state, municipal or governmental agency, which default might have consequences that would materially and adversely affect the condition (financial or other) or operations of the Master Servicer or its properties or might have consequences that would materially adversely affect its performance hereunder;

(v) No litigation is pending or, to the best of the Master Servicer’s knowledge, threatened against the Master Servicer which would prohibit its entering into this Agreement or performing its obligations under this Agreement;

(vi) The Master Servicer shall comply in all material respects in the performance of this Agreement with all reasonable rules and requirements of each insurer under each Required Insurance Policy;

(vii) No information, certificate of an officer, statement furnished in writing or report delivered to the Depositor, any Affiliate of the Depositor or the Trustee by the Master Servicer will, to the knowledge of the Master Servicer, contain any untrue statement of a material fact or omit a material fact necessary to make the information, certificate, statement or report not misleading;

(viii) The Master Servicer has examined each existing, and will examine each new, Subservicing Agreement and is or will be familiar with the terms thereof. The terms of each existing Subservicing Agreement and each designated Subservicer are acceptable to the Master Servicer and any new Subservicing Agreements will comply with the provisions of Section 3.02;

(ix) The Master Servicer is a member of MERS in good standing, and will comply in all material respects with the rules and procedures of MERS in connection with the servicing of the Mortgage Loans that are registered with MERS; and

(x) The Servicing Guide of the Master Servicer requires that the Subservicer for each Mortgage Loan accurately and fully reports its borrower credit files to each of the Credit Repositories in a timely manner.

It is understood and agreed that the representations and warranties set forth in this Section 2.03(a) shall survive delivery of the respective Mortgage Files to the Trustee or any Custodian. Upon discovery by either the Depositor, the Master Servicer, the Trustee or any Custodian of a breach of any representation or warranty set forth in this Section 2.03(a) which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties (any Custodian being so obligated under a Custodial Agreement). Within 90 days of its discovery or its receipt of notice of such breach, the Master Servicer shall either (i) cure such breach in all material respects or (ii) to the extent that such breach is with respect to a Mortgage Loan or a related document, purchase such Mortgage Loan from the Trust Fund at the Purchase Price and in the manner set forth in Section 2.02; provided 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 repurchase must occur within 90 days from the date such breach was discovered. The obligation of the Master Servicer to cure such breach or to so purchase such Mortgage Loan shall constitute the sole remedy in respect of a breach of a representation and warranty set forth in this Section 2.03(a) available to the Certificateholders or the Trustee on behalf of the Certificateholders.

(b) The Depositor hereby represents and warrants to the Trustee for the benefit of the Certificateholders that as of the Closing Date (or, if otherwise specified below, as of the date so specified): (i) immediately prior to the conveyance of the Mortgage Loans to the Trustee, the Depositor had good title to, and was the sole owner of, each Mortgage Loan free and clear of any pledge, lien, encumbrance or security interest (other than rights to servicing and related compensation) and such conveyance validly transfers ownership of the Mortgage Loans to the Trustee free and clear of any pledge, lien, encumbrance or security interest; and (ii) each Mortgage Loan constitutes a qualified mortgage under Section 860G(a)(3)(A) of the Code and Treasury Regulations Section 1.860G-2(a)(1).

It is understood and agreed that the representations and warranties set forth in this Section 2.03(b) shall survive delivery of the respective Mortgage Files to the Trustee or any Custodian.

Upon discovery by any of the Depositor, the Master Servicer, the Trustee or any Custodian of a breach of any of the representations and warranties set forth in this Section 2.03(b) which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties(any Custodian being so obligated under a Custodial Agreement); provided, however, that in the event of a breach of the representation and warranty set forth in Section 2.03(b)(ii), the party discovering such breach shall give such notice within five days of discovery. Within 90 days of its discovery or its receipt of notice of breach, the Depositor shall either (i) cure such breach in all material respects or (ii) purchase such Mortgage Loan from the Trust Fund at the Purchase Price and in the manner set forth in Section 2.02; provided that the Depositor shall have the option to substitute a Qualified Substitute Mortgage Loan or Loans for such Mortgage Loan if such substitution occurs within two years following the Closing Date; provided that if the omission or 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, substitution or repurchase must occur within 90 days from the date such breach was discovered. Any such substitution shall be effected by the Depositor under the same terms and conditions as provided in Section 2.04 for substitutions by Residential Funding. It is understood and agreed that the obligation of the Depositor to cure such breach or to so purchase or substitute for any Mortgage Loan as to which such a breach has occurred and is continuing shall constitute the sole remedy respecting such breach available to the Certificateholders or the Trustee on behalf of the Certificateholders. Notwithstanding the foregoing, the Depositor shall not be required to cure breaches or purchase or substitute for Mortgage Loans as provided in this Section 2.03(b) if the substance of the breach of a representation set forth above also constitutes fraud in the origination of the Mortgage Loan.

Section 2.04. Representations and Warranties of Sellers.

The Depositor, as assignee of Residential Funding under the Assignment Agreement, hereby assigns to the Trustee for the benefit of the Certificateholders all of its right, title and interest in respect of the Assignment Agreement and each Seller’s Agreement applicable to a Mortgage Loan as and to the extent set forth in the Assignment Agreement. Insofar as the Assignment Agreement or such Seller’s Agreement relates to the representations and warranties made by Residential Funding or the related Seller in respect of such Mortgage Loan and any remedies provided thereunder for any breach of such representations and warranties, such right, title and interest may be enforced by the Master Servicer on behalf of the Trustee and the Certificateholders. Upon the discovery by the Depositor, the Master Servicer, the Trustee or any Custodian of a breach of any of the representations and warranties made in a Seller’s Agreement or the Assignment Agreement in respect of any Mortgage Loan or of any Repurchase Event which materially and adversely affects the interests of the Certificateholders in such Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties(any Custodian being so obligated under a Custodial Agreement). The Master Servicer shall promptly notify the related Seller and Residential Funding of such breach or Repurchase Event and request that such Seller or Residential Funding either (i) cure such breach or Repurchase Event in all material respects within 90 days from the date the Master Servicer was notified of such breach or Repurchase Event or (ii) purchase such Mortgage Loan from the Trust Fund at the Purchase Price and in the manner set forth in Section 2.02.

Upon the discovery by the Depositor, the Master Servicer, the Trustee or any Custodian of a breach of any of such representations and warranties set forth in the Assignment Agreement in respect of any Mortgage Loan which materially and adversely affects the interests of the Certificateholders in such Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties (any Custodian being so obligated under a Custodial Agreement) at the same time as notice is given pursuant to the preceding paragraph of any corresponding breach of representation or warranty made in Seller’s Agreement. The Master Servicer shall promptly notify Residential Funding of such breach of a representation or warranty set forth in the Assignment Agreement and request that Residential Funding either (i) cure such breach in all material respects within 90 days from the date the Master Servicer was notified of such breach or (ii) purchase such Mortgage Loan from the Trust Fund within 90 days of the date of such written notice of such breach at the Purchase Price and in the manner set forth in Section 2.02, but only if the Mortgage Loan has not been purchased by the Seller due to a breach of representation and warranty of the related Seller’s Agreement as set forth in the preceding paragraph; provided that Residential Funding shall have the option to substitute a Qualified Substitute Mortgage Loan or Loans for such Mortgage Loan if such substitution occurs within two years following the Closing Date; provided 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. If the breach of representation and warranty that gave rise to the obligation to repurchase or substitute a Mortgage Loan pursuant to Section 4 of the Assignment Agreement was the representation and warranty set forth in clause (xlvii) of Section 4 thereof, then the Master Servicer shall request that Residential Funding pay to the Trust Fund, concurrently with and in addition to the remedies provided in the preceding sentence, an amount equal to any liability, penalty or expense that was actually incurred and paid out of or on behalf of the Trust Fund, and that directly resulted from such breach, or if incurred and paid by the Trust Fund thereafter, concurrently with such payment. In the event that Residential Funding elects to substitute a Qualified Substitute Mortgage Loan or Loans for a Deleted Mortgage Loan pursuant to this Section 2.04, Residential Funding shall deliver to the Trustee for the benefit of the Certificateholders with respect to such Qualified Substitute Mortgage Loan or Loans, the original Mortgage Note, the Mortgage, an Assignment of the Mortgage in recordable form, and such other documents and agreements as are required by Section 2.01, with the Mortgage Note endorsed as required by Section 2.01. No substitution will be made in any calendar month after the Determination Date for such month. Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the Master Servicer and remitted by the Master Servicer to Residential Funding on the next succeeding Distribution Date. For the month of substitution, distributions to the Certificateholders will include the Monthly Payment due on a Deleted Mortgage Loan for such month and thereafter Residential Funding shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Master Servicer shall amend or cause to be amended the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Qualified Substitute Mortgage Loan or Loans and the Master Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee. Upon such substitution, the Qualified Substitute Mortgage Loan or Loans shall be subject to the terms of this Agreement and the related Subservicing Agreement in all respects, the related Seller shall be deemed to have made the representations and warranties with respect to the Qualified Substitute Mortgage Loan made in the related Seller Agreements as of the date of substitution, Residential Funding shall be deemed to have made the representations and warranties with respect to the Qualified Substitute Mortgage Loan (other than those of a statistical nature) contained in the Assignment Agreement as of the date of substitution, and the covenants, representations and warranties set forth in this Section 2.04, and in Section 2.03(b) hereof.

In connection with the substitution of one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer shall determine the amount (if any) by which the aggregate principal balance of all such Qualified Substitute Mortgage Loans as of the date of substitution is less than the aggregate Stated Principal Balance of all such Deleted Mortgage Loans (in each case after application of the principal portion of the Monthly Payments due in the month of substitution that are to be distributed to the Certificateholders in the month of substitution). Residential Funding shall deposit or cause the related Seller to deposit the amount of such shortfall into the Custodial Account on the day of substitution, without any reimbursement therefor. Residential Funding shall give notice in writing to the Trustee of such event, which notice shall be accompanied by an Officers’ Certificate as to the calculation of such shortfall and (subject to Section 10.01(f)) by an Opinion of Counsel to the effect that such substitution will not cause (a) any federal tax to be imposed on the Trust Fund, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(a)(1) of the Code or on “contributions after the startup date” under Section 860G(d)(1) of the Code or (b) any portion of any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding.

It is understood and agreed that the obligation of the Seller or Residential Funding, as the case may be, to cure such breach or purchase (and in the case of Residential Funding to substitute for) such Mortgage Loan as to which such a breach has occurred and is continuing and to make any additional payments required under the Assignment Agreement in connection with a breach of the representation and warranty in clause (xlvii) of Section 4 thereof shall constitute the sole remedy respecting such breach available to the Certificateholders or the Trustee on behalf of the Certificateholders. If the Master Servicer is Residential Funding, then the Trustee shall also have the right to give the notification and require the purchase or substitution provided for in the second preceding paragraph in the event of such a breach of a representation or warranty made by Residential Funding in the Assignment Agreement. In connection with the purchase of or substitution for any such Mortgage Loan by Residential Funding, the Trustee shall assign to Residential Funding all of the right, title and interest in respect of the Seller’s Agreement and the Assignment Agreement applicable to such Mortgage Loan.

Section 2.05. Execution and Authentication of Certificates; Conveyance of REMIC I Regular Interests.

(a) The Trustee acknowledges the assignment to it of the Mortgage Loans and the delivery of the Mortgage Files to it, or any Custodian on its behalf, subject to any exceptions noted, together with the assignment to it of all other assets included in the Trust Fund, receipt of which is hereby acknowledged. Concurrently with such delivery and in exchange therefor, the Trustee, pursuant to the written request of the Depositor executed by an officer of the Depositor, has executed and caused to be authenticated and delivered to or upon the order of the Depositor the Certificates in authorized denominations which evidence ownership of the entire Trust Fund.

(b) The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, assign, set over and otherwise convey in trust to the Trustee without recourse all the right, title and interest of the Depositor in and to the REMIC I Regular Interests for the benefit of the holders of the Regular Certificates and the Class R-II certificates. The Trustee acknowledges receipt of the REMIC I Regular Interests (each of which are uncertificated) and declares that it holds and will hold the same in trust for the exclusive use and benefit of the holders of the Regular Certificates and the Class R-II Certificates. The interests evidenced by the Class R-II Certificate, together with the Regular Certificates, constitute the entire beneficial ownership interest in REMIC II.

Section 2.06. Purposes and Powers of the Trust.

The purpose of the trust, as created hereunder, is to engage in the following activities:

(a) to sell the Certificates to the Depositor in exchange for the Mortgage Loans;

(b) to enter into and perform its obligations under this Agreement;

(c) to engage in those activities that are necessary, suitable or convenient to accomplish the foregoing or are incidental thereto or connected therewith; and

(d) subject to compliance with this Agreement, to engage in such other activities as may be required in connection with conservation of the Trust Fund and the making of distributions to the Certificateholders.

The trust is hereby authorized to engage in the foregoing activities. Notwithstanding the provisions of Section 11.01, the trust shall not engage in any activity other than in connection with the foregoing or other than as required or authorized by the terms of this Agreement while any Certificate is outstanding, and this Section 2.06 may not be amended, without the consent of the Certificateholders evidencing a majority of the aggregate Voting Rights of the Certificates.

ARTICLE III

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

Section 3.01. Master Servicer to Act as Servicer.

(a) The Master Servicer shall service and administer the Mortgage Loans in accordance with the terms of this Agreement and the respective Mortgage Loans, following such procedures as it would employ in its good faith business judgment and which are normal and usual in its general mortgage servicing activities, and shall have full power and authority, acting alone or through Subservicers as provided in Section 3.02, to do any and all things which it may deem necessary or desirable in connection with such servicing and administration. Without limiting the generality of the foregoing, the Master Servicer in its own name or in the name of a Subservicer is hereby authorized and empowered by the Trustee when the Master Servicer or the Subservicer, as the case may be, believes it appropriate in its best judgment, to execute and deliver, on behalf of the Certificateholders and the Trustee or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, or of consent to assumption or modification in connection with a proposed conveyance, or of assignment of any Mortgage and Mortgage Note in connection with the repurchase of a Mortgage Loan and all other comparable instruments, or with respect to the modification or re-recording of a Mortgage for the purpose of correcting the Mortgage, the subordination of the lien of the Mortgage in favor of a public utility company or government agency or unit with powers of eminent domain, the taking of a deed in lieu of foreclosure, the commencement, prosecution or completion of judicial or non-judicial foreclosure, the conveyance of a Mortgaged Property to the related insurer, the acquisition of any property acquired by foreclosure or deed in lieu of foreclosure, or the management, marketing and conveyance of any property acquired by foreclosure or deed in lieu of foreclosure with respect to the Mortgage Loans and with respect to the Mortgaged Properties. The Master Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of the Subservicer, when the Master Servicer or the Subservicer, as the case may be, believes it is appropriate in its best judgment to register any Mortgage Loan on the MERS® System, or cause the removal from the registration of any Mortgage Loan on the MERS® System, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns. Any expenses incurred in connection with the actions described in the preceding sentence shall be borne by the Master Servicer in accordance with Section 3.16(c), with no right of reimbursement; provided, that if, as a result of MERS discontinuing or becoming unable to continue operations in connection with the MERS® System, it becomes necessary to remove any Mortgage Loan from registration on the MERS® System and to arrange for the assignment of the related Mortgages to the Trustee, then any related expenses shall be reimbursable to the Master Servicer as set forth in Section 3.10(a)(ii). Notwithstanding the foregoing, subject to Section 3.07(a), the Master Servicer shall not permit any modification with respect to any Mortgage Loan that would both constitute a sale or exchange of such Mortgage Loan within the meaning of Section 1001 of the Code and any proposed, temporary or final regulations promulgated thereunder (other than in connection with a proposed conveyance or assumption of such Mortgage Loan that is treated as a Principal Prepayment in Full pursuant to Section 3.13(d) hereof) and cause any REMIC created hereunder to fail to qualify as a REMIC under the Code. The Trustee shall furnish the Master Servicer with any powers of attorney and other documents necessary or appropriate to enable the Master Servicer to service and administer the Mortgage Loans. The Trustee shall not be liable for any action taken by the Master Servicer or any Subservicer pursuant to such powers of attorney or other documents. In servicing and administering any Nonsubserviced Mortgage Loan, the Master Servicer shall, to the extent not inconsistent with this Agreement, comply with the Program Guide as if it were the originator of such Mortgage Loan and had retained the servicing rights and obligations in respect thereof.

If the Mortgage relating to a Mortgage Loan did not have a lien senior to the Mortgage Loan on the related Mortgaged Property as of the Cut-off Date, then the Master Servicer, in such capacity, may not consent to the placing of a lien senior to that of the Mortgage on the related Mortgaged Property. If the Mortgage relating to a Mortgage Loan had a lien senior to the Mortgage Loan on the related Mortgaged Property as of the Cut-off Date, then the Master Servicer, in such capacity, may consent to the refinancing of the prior senior lien, provided that the following requirements are met:

(i) (A) the Mortgagor’s debt-to-income ratio resulting from such refinancing is less than the original debt-to-income ratio as set forth on the Mortgage Loan Schedule; provided, however, that in no instance shall the resulting Combined Loan-to-Value Ratio (“Combined Loan-to-Value Ratio”) of such Mortgage Loan be higher than that permitted by the Program Guide; or

(B) the resulting Combined Loan-to-Value Ratio of such Mortgage Loan is no higher than the Combined Loan-to-Value Ratio prior to such refinancing; provided, however, if such refinanced mortgage loan is a “rate and term” mortgage loan (meaning, the Mortgagor does not receive any cash from the refinancing), the Combined Loan-to-Value Ratio may increase to the extent of either (x) the reasonable closing costs of such refinancing or (y) any decrease in the value of the related Mortgaged Property, if the Mortgagor is in good standing as defined by the Program Guide;

(ii) the interest rate, or, in the case of an adjustable rate existing senior lien, the maximum interest rate, for the loan evidencing the refinanced senior lien is no more than 2.0% higher than the interest rate or the maximum interest rate, as the case may be, on the loan evidencing the existing senior lien immediately prior to the date of such refinancing; provided, however (A) if the loan evidencing the existing senior lien prior to the date of refinancing has an adjustable rate and the loan evidencing the refinanced senior lien has a fixed rate, then the current interest rate on the loan evidencing the refinanced senior lien may be up to 2.0% higher than the then-current loan rate of the loan evidencing the existing senior lien and (B) if the loan evidencing the existing senior lien prior to the date of refinancing has a fixed rate and the loan evidencing the refinanced senior lien has an adjustable rate, then the maximum interest rate on the loan evidencing the refinanced senior lien shall be less than or equal to (x) the interest rate on the loan evidencing the existing senior lien prior to the date of refinancing plus (y) 2.0%; and

(iii) the loan evidencing the refinanced senior lien is not subject to negative amortization.

(b) The Master Servicer shall, to the extent consistent with the servicing standards set forth herein, take whatever actions as may be necessary to file a claim under or enforce or allow the Trustee to file a claim under or enforce any title insurance policy with respect to any Mortgage Loan including, without limitation, joining in or causing any Seller or Subservicer (or any other party in possession of any title insurance policy) to join in any claims process, negotiations, actions or proceedings necessary to make a claim under or enforce any title insurance policy. Notwithstanding anything in this Agreement to the contrary, the Master Servicer shall not (unless the Mortgagor is in default with respect to the Mortgage Loan or such default is, in the judgment of the Master Servicer, reasonably foreseeable) make or permit any modification, waiver, or amendment of any term of any Mortgage Loan that would both (i) effect an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or final, temporary or proposed Treasury regulations promulgated thereunder) (other than in connection with a proposed conveyance or assumption of such Mortgage Loan that is treated as a Principal Prepayment in Full pursuant to Section 3.13(d) hereof) and (ii) cause any REMIC formed hereunder to fail to qualify as a REMIC under the Code or the imposition of any tax on “prohibited transactions” or “contributions” after the startup date under the REMIC Provisions.

(c) In connection with servicing and administering the Mortgage Loans, the Master Servicer and any Affiliate of the Master Servicer (i) may perform services such as appraisals and brokerage services that are customarily provided by Persons other than servicers of mortgage loans, and shall be entitled to reasonable compensation therefor in accordance with Section 3.10 and (ii) may, at its own discretion and on behalf of the Trustee, obtain credit information in the form of a “credit score” from a Credit Repository.

(d) All costs incurred by the Master Servicer or by Subservicers in effecting the timely payment of taxes and assessments on the properties subject to the Mortgage Loans shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the amount owing under the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loan so permit, and such costs shall be recoverable to the extent permitted by Section 3.10(a)(ii).

(e) The Master Servicer may enter into one or more agreements in connection with the offering of pass-through certificates evidencing interests in one or more of the Certificates providing for the payment by the Master Servicer of amounts received by the Master Servicer as servicing compensation hereunder and required to cover certain Prepayment Interest Shortfalls on the Mortgage Loans, which payment obligation will thereafter be an obligation of the Master Servicer hereunder.

(f) The relationship of the Master Servicer (and of any successor to the Master Servicer) to the Depositor under this Agreement is intended by the parties to be that of an independent contractor and not that of a joint venturer, partner or agent.

(g) The Master Servicer shall comply with the terms of Section 9 of the Assignment Agreement.

Section

3.02. Subservicing Agreements Between Master Servicer and Subservicers; Enforcement of Subservicers’ Obligations.

(a) The Master Servicer may continue in effect Subservicing Agreements entered into by Residential Funding and Subservicers prior to the execution and delivery of this Agreement, and may enter into new Subservicing Agreements with Subservicers, for the servicing and administration of all or some of the Mortgage Loans. Each Subservicer shall be either (i) an institution the accounts of which are insured by the FDIC or (ii) another entity that engages in the business of originating or servicing mortgage loans, and in either case shall be authorized to transact business in the state or states in which the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to enable the Subservicer to perform its obligations hereunder and under the Subservicing Agreement, and in either case shall be a Freddie Mac, Fannie Mae or HUD approved mortgage servicer. Each Subservicer of a Mortgage Loan shall be entitled to receive and retain, as provided in the related Subservicing Agreement and in Section 3.07, the related Subservicing Fee from payments of interest received on such Mortgage Loan after payment of all amounts required to be remitted to the Master Servicer in respect of such Mortgage Loan. For any Mortgage Loan that is a Nonsubserviced Mortgage Loan, the Master Servicer shall be entitled to receive and retain an amount equal to the Subservicing Fee from payments of interest. Unless the context otherwise requires, references in this Agreement to actions taken or to be taken by the Master Servicer in servicing the Mortgage Loans include actions taken or to be taken by a Subservicer on behalf of the Master Servicer. Each Subservicing Agreement will be upon such terms and conditions as are generally required by, permitted by or consistent with the Program Guide and are not inconsistent with this Agreement and as the Master Servicer and the Subservicer have agreed. With the approval of the Master Servicer, a Subservicer may delegate its servicing obligations to third-party servicers, but such Subservicer will remain obligated under the related Subservicing Agreement. The Master Servicer and a Subservicer may enter into amendments thereto or a different form of Subservicing Agreement, and the form referred to or included in the Program Guide is merely provided for information and shall not be deemed to limit in any respect the discretion of the Master Servicer to modify or enter into different Subservicing Agreements; provided, however, that any such amendments or different forms shall be consistent with and not violate the provisions of either this Agreement or the Program Guide in a manner which would materially and adversely affect the interests of the Certificateholders. The Program Guide and any other Subservicing Agreement entered into between the Master Servicer and any Subservicer shall require the Subservicer to accurately and fully report its borrower credit files to each of the Credit Repositories in a timely manner.

(b) As part of its servicing activities hereunder, the Master Servicer, for the benefit of the Trustee and the Certificateholders, shall use its best reasonable efforts to enforce the obligations of each Subservicer under the related Subservicing Agreement and of each Seller under the related Seller’s Agreement, to the extent that the non-performance of any such obligation would have a material and adverse effect on a Mortgage Loan, including, without limitation, the obligation to purchase a Mortgage Loan on account of defective documentation, as described in Section 2.02, or on account of a breach of a representation or warranty, as described in Section 2.04. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Subservicing Agreements or Seller’s Agreements, as appropriate, 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 would employ in its good faith business judgment and which are normal and usual in its general mortgage servicing activities. The Master Servicer shall pay the costs of such enforcement at its own expense, and shall be reimbursed therefor only (i) from a general recovery resulting from such enforcement to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loan or (ii) from a specific recovery of costs, expenses or attorneys fees against the party against whom such enforcement is directed. For purposes of clarification only, the parties agree that the foregoing is not intended to, and does not, limit the ability of the Master Servicer to be reimbursed for expenses that are incurred in connection with the enforcement of a Seller’s obligations and are reimbursable pursuant to Section 3.10(a)(vii).

Section 3.03. Successor Subservicers.

The Master Servicer shall be entitled to terminate any Subservicing Agreement that may exist in accordance with the terms and conditions of such Subservicing Agreement and without any limitation by virtue of this Agreement; provided, however, that in the event of termination of any Subservicing Agreement by the Master Servicer or the Subservicer, the Master Servicer shall either act as servicer of the related Mortgage Loan or enter into a Subservicing Agreement with a successor Subservicer which will be bound by the terms of the related Subservicing Agreement. If the Master Servicer or any Affiliate of Residential Funding acts as servicer, it will not assume liability for the representations and warranties of the Subservicer which it replaces. If the Master Servicer enters into a Subservicing Agreement with a successor Subservicer, the Master Servicer shall use reasonable efforts to have the successor Subservicer assume liability for the representations and warranties made by the terminated Subservicer in respect of the related Mortgage Loans and, in the event of any such assumption by the successor Subservicer, the Master Servicer may, in the exercise of its business judgment, release the terminated Subservicer from liability for such representations and warranties.

Section 3.04. Liability of the Master Servicer.

Notwithstanding any Subservicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between the Master Servicer or a Subservicer or reference to actions taken through a Subservicer or otherwise, the Master Servicer shall remain obligated and liable to the Trustee, and Certificateholders for the servicing and administering of the Mortgage Loans in accordance with the provisions of Section 3.01 without diminution of such obligation or liability by virtue of such Subservicing Agreements or arrangements or by virtue of indemnification from the Subservicer or the Depositor and to the same extent and under the same terms and conditions as if the Master Servicer alone were servicing and administering the Mortgage Loans. The Master Servicer shall be entitled to enter into any agreement with a Subservicer or Seller for indemnification of the Master Servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

Section 3.05. No Contractual Relationship Between Subservicer and Trustee or Certificateholders.

Any Subservicing Agreement that may be entered into and any other transactions or services relating to the Mortgage Loans involving a Subservicer in its capacity as such and not as an originator shall be deemed to be between the Subservicer and the Master Servicer alone, and the Trustee and Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Subservicer in its capacity as such except as set forth in Section 3.06. The foregoing provision shall not in any way limit a Subservicer’s obligation to cure an omission or defect or to repurchase a Mortgage Loan as referred to in Section 2.02 hereof.

Section 3.06. Assumption or Termination of Subservicing Agreements by Trustee.

(a) In the event the Master Servicer shall for any reason no longer be the master servicer (including by reason of an Event of Default), the Trustee, as successor Master Servicer, its designee or its successor shall thereupon assume all of the rights and obligations of the Master Servicer under each Subservicing Agreement that may have been entered into. The Trustee, its designee or the successor servicer for the Trustee shall be deemed to have assumed all of the Master Servicer’s interest therein and to have replaced the Master Servicer as a party to the Subservicing Agreement to the same extent as if the Subservicing Agreement had been assigned to the assuming party except that the Master Servicer shall not thereby be relieved of any liability or obligations under the Subservicing Agreement.

(b) The Master Servicer shall, upon request of the Trustee but at the expense of the Master Servicer, deliver to the assuming party all documents and records relating to each Subservicing Agreement and the Mortgage Loans then being serviced and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of each Subservicing Agreement to the assuming party.

Section 3.07. Collection of Certain Mortgage Loan Payments; Deposits to Custodial Account.

(a) The Master Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the Mortgage Loans, and shall, to the extent such procedures shall be consistent with this Agreement and the terms and provisions of any related Primary Insurance Policy, follow such collection procedures as it would employ in its good faith business judgment and which are normal and usual in its general mortgage servicing activities. Consistent with the foregoing, the Master Servicer may in its discretion (subject to the terms and conditions of the Assignment Agreement) (i) waive any late payment charge or any prepayment charge or penalty interest in connection with the prepayment of a Mortgage Loan and (ii) extend the Due Date for payments due on a Mortgage Loan in accordance with the Program Guide, provided, however, that the Master Servicer shall first determine that any such waiver or extension will not impair the coverage of any related Primary Insurance Policy or materially adversely affect the lien of the related Mortgage. Notwithstanding anything in this Section to the contrary, the Master Servicer or any Subservicer shall not enforce any prepayment charge to the extent that such enforcement would violate any applicable law. In the event of any such arrangement, the Master Servicer shall make timely advances on the related Mortgage Loan during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements unless otherwise agreed to by the Holders of the Classes of Certificates affected thereby; provided, however, that no such extension shall be made if any advance would be a Nonrecoverable Advance. Consistent with the terms of this Agreement, the Master Servicer may also waive, modify or vary any term of any Mortgage Loan or consent to the postponement of strict compliance with any such term or in any manner grant indulgence to any Mortgagor if in the Master Servicer’s determination such waiver, modification, postponement or indulgence is not materially adverse to the interests of the Certificateholders(taking into account any estimated Realized Loss that might result absent such action), provided, however, that the Master Servicer may not modify materially or permit any Subservicer to modify any Mortgage Loan, including without limitation any modification that would change the Mortgage Rate, forgive the payment of any principal or interest (unless in connection with the liquidation of the related Mortgage Loan or except in connection with prepayments to the extent that such reamortization is not inconsistent with the terms of the Mortgage Loan), capitalize any amounts owing on the Mortgage Loan by adding such amount to the outstanding principal balance of the Mortgage Loan, or extend the final maturity date of such Mortgage Loan, unless such Mortgage Loan is in default or, in the judgment of the Master Servicer, such default is reasonably foreseeable. No such modification shall reduce the Mortgage Rate on a Mortgage Loan below the greater of (A) one-half of the Mortgage Rate as in effect on the Cut-off Date and (B) one-half of the Mortgage Rate as in effect on the date of such modification, but not less than the sum of the Servicing Fee Rate and the per annum rate at which the Subservicing Fee accrues. The final maturity date for any Mortgage Loan shall not be extended beyond the Maturity Date. Also, the aggregate principal balance of all Reportable Modified Mortgage Loans subject to Servicing Modifications (measured at the time of the Servicing Modification and after giving effect to any Servicing Modification) can be no more than five percent of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date, provided, that such limit may be increased from time to time if each Rating Agency provides written confirmation that an increase in excess of that limit will 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. In addition, any amounts owing on a Mortgage Loan added to the outstanding principal balance of such Mortgage Loan must be fully amortized over the term of such Mortgage Loan, and such amounts may be added to the outstanding principal balance of a Mortgage Loan only once during the life of such Mortgage Loan. Also, the addition of such amounts described in the preceding sentence shall be implemented in accordance with the Program Guide and may be implemented only by Subservicers that have been approved by the Master Servicer for such purposes. In connection with any Curtailment of a Mortgage Loan, the Master Servicer, to the extent not inconsistent with the terms of the Mortgage Note and local law and practice, may permit the Mortgage Loan to be re-amortized such that the Monthly Payment is recalculated as an amount that will fully amortize the remaining principal balance thereof by the original maturity date based on the original Mortgage Rate; provided, that such reamortization shall not be permitted if it would constitute a reissuance of the Mortgage Loan for federal income tax purposes.

(b) The Master Servicer shall establish and maintain a Custodial Account in which the Master Servicer shall deposit or cause to be deposited on a daily basis, except as otherwise specifically provided herein, the following payments and collections remitted by Subservicers or received by it in respect of the Mortgage Loans subsequent to the Cut-off Date (other than in respect of Monthly Payments due before or in the month of the Cut-off Date):

(i) All payments on account of principal, including Principal Prepayments made by Mortgagors on the Mortgage Loans and the principal component of any Subservicer Advance or of any REO Proceeds received in connection with an REO Property for which an REO Disposition has occurred;

(ii) All payments on account of interest at the Adjusted Mortgage Rate on the Mortgage Loans, including the interest component of any Subservicer Advance or of any REO Proceeds received in connection with an REO Property for which an REO Disposition has occurred;

(iii) Insurance Proceeds, Subsequent Recoveries and Liquidation Proceeds (net of any related expenses of the Subservicer);

(iv) All proceeds of any Mortgage Loans purchased pursuant to Section 2.02, 2.03, 2.04 or 4.07 (including amounts received from Residential Funding pursuant to the last paragraph of Section 4 of the Assignment Agreement in respect of any liability, penalty or expense that resulted from a breach of the representation and warranty set forth in clause (xlvii) of Section 4 of the Assignment Agreement) and all amounts required to be deposited in connection with the substitution of a Qualified Substitute Mortgage Loan pursuant to Section 2.03 or 2.04; and

(v) Any amounts required to be deposited pursuant to Section 3.07(c) and any payments or collections received in the nature of prepayment charges.

The foregoing requirements for deposit in the Custodial Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments on the Mortgage Loans which are not part of the Trust Fund (consisting of Monthly Payments due before or in the month of the Cut-off Date) and payments or collections consisting of late payment charges or assumption fees may but need not be deposited by the Master Servicer in the Custodial Account. In the event any amount not required to be deposited in the Custodial Account is so deposited, the Master Servicer may at any time withdraw such amount from the Custodial Account, any provision herein to the contrary notwithstanding. The Custodial Account may contain funds that belong to one or more trust funds created for mortgage pass-through certificates of other series and may contain other funds respecting payments on mortgage loans belonging to the Master Servicer or serviced or master serviced by it on behalf of others. Notwithstanding such commingling of funds, the Master Servicer shall keep records that accurately reflect the funds on deposit in the Custodial Account that have been identified by it as being attributable to the Mortgage Loans. With respect to Insurance Proceeds, Liquidation Proceeds, REO Proceeds, Subsequent Recoveries and the proceeds of the purchase of any Mortgage Loan pursuant to Sections 2.02, 2.03, 2.04 and 4.07 received in any calendar month, the Master Servicer may elect to treat such amounts as included in the Available Distribution Amount for the Distribution Date in the month of receipt, but is not obligated to do so. If the Master Servicer so elects, such amounts will be deemed to have been received (and any related Realized Loss shall be deemed to have occurred) on the last day of the month prior to the receipt thereof.

(c) The Master Servicer shall use its best efforts to cause the institution maintaining the Custodial Account to invest the funds in the Custodial Account attributable to the Mortgage Loans in Permitted Investments which shall mature not later than the Certificate Account Deposit Date next following the date of such investment (with the exception of the Amount Held for Future Distribution) and which shall not be sold or disposed of prior to their maturities. All income and gain realized from any such investment shall be for the benefit of the Master Servicer as additional servicing compensation and shall be subject to its withdrawal or order from time to time. The amount of any losses incurred in respect of any such investments attributable to the investment of amounts in respect of the Mortgage Loans shall be deposited in the Custodial Account by the Master Servicer out of its own funds immediately as realized.

(d) The Master Servicer shall give notice to the Trustee and the Depositor of any change in the location of the Custodial Account and the location of the Certificate Account prior to the use thereof.

Section 3.08. Subservicing Accounts; Servicing Accounts.

(a) In those cases where a Subservicer is servicing a Mortgage Loan pursuant to a Subservicing Agreement, the Master Servicer shall cause the Subservicer, pursuant to the Subservicing Agreement, to establish and maintain one or more Subservicing Accounts which shall be an Eligible Account or, if such account is not an Eligible Account, shall generally satisfy the requirements of the Program Guide and be otherwise acceptable to the Master Servicer and each Rating Agency. The Subservicer will be required thereby to deposit into the Subservicing Account on a daily basis all proceeds of Mortgage Loans received by the Subservicer, less its Subservicing Fees and unreimbursed advances and expenses, to the extent permitted by the Subservicing Agreement. If the Subservicing Account is not an Eligible Account, the Master Servicer shall be deemed to have received such monies upon receipt thereof by the Subservicer. The Subservicer shall not be required to deposit in the Subservicing Account payments or collections in the nature of late charges or assumption fees, or payments or collections received in the nature of prepayment charges to the extent that the Subservicer is entitled to retain such amounts pursuant to the Subservicing Agreement. On or before the date specified in the Program Guide, but in no event later than the Determination Date, the Master Servicer shall cause the Subservicer, pursuant to the Subservicing Agreement, to remit to the Master Servicer for deposit in the Custodial Account all funds held in the Subservicing Account with respect to each Mortgage Loan serviced by such Subservicer that are required to be remitted to the Master Servicer. The Subservicer will also be required, pursuant to the Subservicing Agreement, to advance on such scheduled date of remittance amounts equal to any scheduled monthly installments of principal and interest less its Subservicing Fees on any Mortgage Loans for which payment was not received by the Subservicer. This obligation to advance with respect to each Mortgage Loan will continue up to and including the first of the month following the date on which the related Mortgaged Property is sold at a foreclosure sale or is acquired by the Trust Fund by deed in lieu of foreclosure or otherwise. All such advances received by the Master Servicer shall be deposited promptly by it in the Custodial Account.

(b) The Subservicer may also be required, pursuant to the Subservicing Agreement, to remit to the Master Servicer for deposit in the Custodial Account interest at the Adjusted Mortgage Rate (or Modified Net Mortgage Rate plus the rate per annum at which the Servicing Fee accrues in the case of a Modified Mortgage Loan) on any Curtailment received by such Subservicer in respect of a Mortgage Loan from the related Mortgagor during any month that is to be applied by the Subservicer to reduce the unpaid principal balance of the related Mortgage Loan as of the first day of such month, from the date of application of such Curtailment to the first day of the following month. Any amounts paid by a Subservicer pursuant to the preceding sentence shall be for the benefit of the Master Servicer as additional servicing compensation and shall be subject to its withdrawal or order from time to time pursuant to Sections 3.10(a)(iv) and (v).

(c) In addition to the Custodial Account and the Certificate Account, the Master Servicer shall for any Nonsubserviced Mortgage Loan, and shall cause the Subservicers for Subserviced Mortgage Loans to, establish and maintain one or more Servicing Accounts and deposit and retain therein all collections from the Mortgagors (or advances from Subservicers) for the payment of taxes, assessments, hazard insurance premiums, Primary Insurance Policy premiums, if applicable, or comparable items for the account of the Mortgagors. Each Servicing Account shall satisfy the requirements for a Subservicing Account and, to the extent permitted by the Program Guide or as is otherwise acceptable to the Master Servicer, may also function as a Subservicing Account. Withdrawals of amounts related to the Mortgage Loans from the Servicing Accounts may be made only to effect timely payment of taxes, assessments, hazard insurance premiums, Primary Insurance Policy premiums, if applicable, or comparable items, to reimburse the Master Servicer or Subservicer out of related collections for any payments made pursuant to Sections 3.11 (with respect to the Primary Insurance Policy) and 3.12(a) (with respect to hazard insurance), to refund to any Mortgagors any sums as may be determined to be overages, to pay interest, if required, to Mortgagors on balances in the Servicing Account or to clear and terminate the Servicing Account at the termination of this Agreement in accordance with Section 9.01 or in accordance with the Program Guide. As part of its servicing duties, the Master Servicer shall, and the Subservicers will, pursuant to the Subservicing Agreements, be required to pay to the Mortgagors interest on funds in this account to the extent required by law.

(d) The Master Servicer shall advance the payments referred to in the preceding subsection that are not timely paid by the Mortgagors or advanced by the Subservicers on the date when the tax, premium or other cost for which such payment is intended is due, but the Master Servicer shall be required so to advance only to the extent that such advances, in the good faith judgment of the Master Servicer, will be recoverable by the Master Servicer out of Insurance Proceeds, Liquidation Proceeds or otherwise.

Section 3.09. Access to Certain Documentation and Information Regarding the Mortgage Loans.

In the event that compliance with this Section 3.09 shall make any Class of Certificates legal for investment by federally insured savings and loan associations, the Master Servicer shall provide, or cause the Subservicers to provide, to the Trustee, the Office of Thrift Supervision or the FDIC and the supervisory agents and examiners thereof access to the documentation regarding the Mortgage Loans required by applicable regulations of the Office of Thrift Supervision, such access being afforded without charge but only upon reasonable request and during normal business hours at the offices designated by the Master Servicer. The Master Servicer shall permit such representatives to photocopy any such documentation and shall provide equipment for that purpose at a charge reasonably approximating the cost of such photocopying to the Master Servicer.

Section 3.10. Permitted Withdrawals from the Custodial Account.

(a) The Master Servicer may, from time to time as provided herein, make withdrawals from the Custodial Account of amounts on deposit therein pursuant to Section 3.07 that are attributable to the Mortgage Loans for the following purposes:

(i) to make deposits into the Certificate Account in the amounts and in the manner provided for in Section 4.01;

(ii) to reimburse itself or the related Subservicer for previously unreimbursed Advances, Servicing Advances or other expenses made pursuant to Sections 3.01, 3.07(a), 3.08, 3.11, 3.12(a), 3.14 and 4.04 or otherwise reimbursable pursuant to the terms of this Agreement, such withdrawal right being limited to amounts received on the related Mortgage Loans (including, for this purpose, REO Proceeds, Insurance Proceeds, Liquidation Proceeds and proceeds from the purchase of a Mortgage Loan pursuant to Section 2.02, 2.03, 2.04 or 4.07) which represent (A) Late Collections of Monthly Payments for which any such advance was made in the case of Subservicer Advances or Advances pursuant to Section 4.04 and (B) recoveries of amounts in respect of which such advances were made in the case of Servicing Advances;

(iii) to pay to itself or the related Subservicer (if not previously retained by such Subservicer) out of each payment received by the Master Servicer on account of interest on a Mortgage Loan as contemplated by Sections 3.14 and 3.16, an amount equal to that remaining portion of any such payment as to interest (but not in excess of the Servicing Fee and the Subservicing Fee, if not previously retained) which, when deducted, will result in the remaining amount of such interest being interest at a rate per annum equal to the Net Mortgage Rate (or Modified Net Mortgage Rate in the case of a Modified Mortgage Loan) on the amount specified in the amortization schedule of the related Mortgage Loan as the principal balance thereof at the beginning of the period respecting which such interest was paid after giving effect to any previous Curtailments;

(iv) to pay to itself as additional servicing compensation any interest or investment income earned on funds and other property deposited in or credited to the Custodial Account that it is entitled to withdraw pursuant to Section 3.07(c);

(v) to pay to itself as additional servicing compensation any Foreclosure Profits, and any amounts remitted by Subservicers as interest in respect of Curtailments pursuant to Section 3.08(b);

(vi) to pay to itself, a Subservicer, a Seller, Residential Funding, the Depositor or any other appropriate Person, as the case may be, with respect to each Mortgage Loan or property acquired in respect thereof that has been purchased or otherwise transferred pursuant to Section 2.02, 2.03, 2.04, 4.07 or 9.01, all amounts received thereon and not required to be distributed to Certificateholders as of the date on which the related Stated Principal Balance or Purchase Price is determined;

(vii) to reimburse itself or the related Subservicer for any Nonrecoverable Advance or Advances in the manner and to the extent provided in subsection (c) below, and any Advance or Servicing Advance made in connection with a modified Mortgage Loan that is in default or, in the judgment of the Master Servicer, default is reasonably foreseeable pursuant to Section 3.07(a), to the extent the amount of the Advance or Servicing Advance was added to the Stated Principal Balance of the Mortgage Loan in a prior calendar month;

(viii) to reimburse itself or the Depositor for expenses incurred by and reimbursable to it or the Depositor pursuant to Section 3.01(a), 3.11, 3.13, 3.14(c), 6.03, 10.01 or otherwise, or in connection with enforcing any repurchase, substitution or indemnification obligation of any Seller (other than the Depositor or an Affiliate of the Depositor) pursuant to the related Seller’s Agreement;

(ix) to reimburse itself for amounts expended by it (a) pursuant to Section 3.14 in good faith in connection with the restoration of property damaged by an Uninsured Cause, and (b) in connection with the liquidation of a Mortgage Loan or disposition of an REO Property to the extent not otherwise reimbursed pursuant to clause (ii) or (viii) above; and

(x) to withdraw any amount deposited in the Custodial Account that was not required to be deposited therein pursuant to Section 3.07, including any payoff fees or penalties or any other additional amounts payable to the Master Servicer or Subservicer pursuant to the terms of the Mortgage Note.

(b) Since, in connection with withdrawals pursuant to clauses (ii), (iii), (v) and (vi), the Master Servicer’s entitlement thereto is limited to collections or other recoveries on the related Mortgage Loan, the Master Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the Custodial Account pursuant to such clauses.

(c) The Master Servicer shall be entitled to reimburse itself or the related Subservicer for any advance made in respect of a Mortgage Loan that the Master Servicer determines to be a Nonrecoverable Advance by withdrawal from the Custodial Account of amounts on deposit therein attributable to the Mortgage Loans on any Certificate Account Deposit Date succeeding the date of such determination. Such right of reimbursement in respect of a Nonrecoverable Advance relating to an Advance made pursuant to Section 4.04 on any such Certificate Account Deposit Date shall be limited to an amount not exceeding the portion of such advance previously paid to Certificateholders (and not theretofore reimbursed to the Master Servicer or the related Subservicer).

Section 3.11. Maintenance of Primary Insurance Coverage.

(a) The Master Servicer shall not take, or permit any Subservicer to take, any action which would result in noncoverage under any applicable Primary Insurance Policy of any loss which, but for the actions of the Master Servicer or Subservicer, would have been covered thereunder. To the extent coverage is available, the Master Servicer shall keep or cause to be kept in full force and effect each such Primary Insurance Policy until the principal balance of the related Mortgage Loan secured by a Mortgaged Property is reduced to 80% or less of the Appraised Value at origination in the case of such a Mortgage Loan having a Loan-to-Value Ratio at origination in excess of 80%, provided that such Primary Insurance Policy was in place as of the Cut-off Date and the Master Servicer had knowledge of such Primary Insurance Policy. The Master Servicer shall not cancel or refuse to renew any such Primary Insurance Policy applicable to a Nonsubserviced Mortgage Loan, or consent to any Subservicer canceling or refusing to renew any such Primary Insurance Policy applicable to a Mortgage Loan subserviced by it, that is in effect at the date of the initial issuance of the Certificates and is required to be kept in force hereunder unless the replacement Primary Insurance Policy for such canceled or non-renewed policy is maintained with an insurer whose claims-paying ability is acceptable to each Rating Agency for mortgage pass-through certificates having a rating equal to or better than the lower of the then-current rating or the rating assigned to the Certificates as of the Closing Date by such Rating Agency.

(b) In connection with its activities as administrator and servicer of the Mortgage Loans, the Master Servicer agrees to present or to cause the related Subservicer to present, on behalf of the Master Servicer, the Subservicer, if any, the Trustee and Certificateholders, claims to the insurer under any Primary Insurance Policies, in a timely manner in accordance with such policies, and, in this regard, to take or cause to be taken such reasonable action as shall be necessary to permit recovery under any Primary Insurance Policies respecting defaulted Mortgage Loans. Pursuant to Section 3.07, any Insurance Proceeds collected by or remitted to the Master Servicer under any Primary Insurance Policies shall be deposited in the Custodial Account, subject to withdrawal pursuant to Section 3.10.

Section 3.12. Maintenance of Fire Insurance and Omissions and Fidelity Coverage.

(a) The Master Servicer shall cause to be maintained for each Mortgage Loan fire insurance with extended coverage in an amount which is equal to the lesser of the principal balance owing on such Mortgage Loan (together with the principal balance of any mortgage loan secured by a lien that is senior to the Mortgage Loan) or 100% of the insurable value of the improvements; provided, however, that such coverage may not be less than the minimum amount required to fully compensate for any loss or damage on a replacement cost basis. To the extent it may do so without breaching the related Subservicing Agreement, the Master Servicer shall replace any Subservicer that does not cause such insurance, to the extent it is available, to be maintained. The Master Servicer shall also cause to be maintained on property acquired upon foreclosure, or deed in lieu of foreclosure, of any Mortgage Loan, fire insurance with extended coverage in an amount which is at least equal to the amount necessary to avoid the application of any co-insurance clause contained in the related hazard insurance policy. Pursuant to Section 3.07, any amounts collected by the Master Servicer under any such policies (other than amounts to be applied to the restoration or repair of the related Mortgaged Property or property thus acquired or amounts released to the Mortgagor in accordance with the Master Servicer’s normal servicing procedures) shall be deposited in the Custodial Account, subject to withdrawal pursuant to Section 3.10. Any cost incurred by the Master Servicer in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to Certificateholders, be added to the amount owing under the Mortgage Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs shall be recoverable by the Master Servicer out of related late payments by the Mortgagor or out of Insurance Proceeds and Liquidation Proceeds to the extent permitted by Section 3.10. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor or maintained on property acquired in respect of a Mortgage 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. Whenever the improvements securing a Mortgage Loan are located at the time of origination of such Mortgage Loan in a federally designated special flood hazard area, the Master Servicer shall cause flood insurance (to the extent available) to be maintained in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the amount required to compensate for any loss or damage to the Mortgaged Property on a replacement cost basis and (ii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program (assuming that the area in which such Mortgaged Property is located is participating in such program).

In the event that the Master Servicer shall obtain and maintain a blanket fire insurance policy with extended coverage insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations as set forth in the first sentence of this Section 3.12(a), it being understood and agreed that such policy may contain a deductible clause, in which case the Master Servicer shall, in the event that there shall not have been maintained on the related Mortgaged Property a policy complying with the first sentence of this Section 3.12(a) and there shall have been a loss which would have been covered by such policy, deposit in the Certificate Account the amount not otherwise payable under the blanket policy because of such deductible clause. Any such deposit by the Master Servicer shall be made on the Certificate Account Deposit Date next preceding the Distribution Date which occurs in the month following the month in which payments under any such policy would have been deposited in the Custodial Account. In connection with its activities as administrator and servicer of the Mortgage Loans, the Master Servicer agrees to present, on behalf of itself, the Trustee and Certificateholders, claims under any such blanket policy.

(b) The Master Servicer shall obtain and maintain at its own expense and keep in full force and effect throughout the term of this Agreement a blanket fidelity bond and an errors and omissions insurance policy covering the Master Servicer’s officers and employees and other persons acting on behalf of the Master Servicer in connection with its activities under this Agreement. The amount of coverage shall be at least equal to the coverage that would be required by Fannie Mae or Freddie Mac, whichever is greater, with respect to the Master Servicer if the Master Servicer were servicing and administering the Mortgage Loans for Fannie Mae or Freddie Mac. In the event that any such bond or policy ceases to be in effect, the Master Servicer shall obtain a comparable replacement bond or policy from an issuer or insurer, as the case may be, meeting the requirements, if any, of the Program Guide and acceptable to the Depositor. Coverage of the Master Servicer under a policy or bond obtained by an Affiliate of the Master Servicer and providing the coverage required by this Section 3.12(b) shall satisfy the requirements of this Section 3.12(b).

Section 3.13. Enforcement of Due-on-Sale Clauses; Assumption and Modification Agreements; Certain Assignments.

(a) When any Mortgaged Property is conveyed by the Mortgagor, the Master Servicer or Subservicer, to the extent it has knowledge of such conveyance, shall enforce any due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent permitted under applicable law and governmental regulations, but only to the extent that such enforcement will not adversely affect or jeopardize coverage under any Required Insurance Policy. Notwithstanding the foregoing: (i) the Master Servicer shall not be deemed to be in default under this Section 3.13(a) by reason of any transfer or assumption which the Master Servicer is restricted by law from preventing; and (ii) if the Master Servicer determines that it is reasonably likely that any Mortgagor will bring, or if any Mortgagor does bring, legal action to declare invalid or otherwise avoid enforcement of a due-on-sale clause contained in any Mortgage Note or Mortgage, the Master Servicer shall not be required to enforce the due-on-sale clause or to contest such action.

(b) Subject to the Master Servicer’s duty to enforce any due-on-sale clause to the extent set forth in Section 3.13(a), in any case in which a Mortgaged Property is to be conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption or modification agreement or supplement to the Mortgage Note or Mortgage which requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the Mortgage Loan, the Master Servicer is authorized, subject to the requirements of the sentence next following, to execute and deliver, on behalf of the Trustee, the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person; provided, however, none of such terms and requirements shall both constitute a “significant modification” effecting an exchange or reissuance of such Mortgage Loan under the Code (or final, temporary or proposed Treasury regulations promulgated thereunder) and cause any REMIC created hereunder to fail to qualify as a REMIC under the Code or the imposition of any tax on “prohibited transactions” or “contributions” after the Startup Date under the REMIC Provisions. The Master Servicer shall execute and deliver such documents only if it reasonably determines that (i) its execution and delivery thereof will not conflict with or violate any terms of this Agreement or cause the unpaid balance and interest on the Mortgage Loan to be uncollectible in whole or in part, (ii) any required consents of insurers under any Required Insurance Policies have been obtained and (iii) subsequent to the closing of the transaction involving the assumption or transfer (A) the Mortgage Loan will continue to be secured by a first mortgage lien pursuant to the terms of the Mortgage, (B) such transaction will not adversely affect the coverage under any Required Insurance Policies, (C) the Mortgage Loan will fully amortize over the remaining term thereof, (D) no material term of the Mortgage Loan (including the interest rate on the Mortgage Loan) will be altered nor will the term of the Mortgage Loan be changed and (E) if the seller/transferor of the Mortgaged Property is to be released from liability on the Mortgage Loan, the buyer/transferee of the Mortgaged Property would be qualified to assume the Mortgage Loan based on generally comparable credit quality and such release will not (based on the Master Servicer’s or Subservicer’s good faith determination) adversely affect the collectability of the Mortgage Loan. Upon receipt of appropriate instructions from the Master Servicer in accordance with the foregoing, the Trustee shall execute any necessary instruments for such assumption or substitution of liability as directed by the Master Servicer. Upon the closing of the transactions contemplated by such documents, the Master Servicer shall cause the originals or true and correct copies of the assumption agreement, the release (if any), or the modification or supplement to the Mortgage Note or Mortgage to be delivered to the Trustee or the Custodian and deposited with the Mortgage File for such Mortgage Loan. Any fee collected by the Master Servicer or such related Subservicer for entering into an assumption or substitution of liability agreement will be retained by the Master Servicer or such Subservicer as additional servicing compensation.

(c) The Master Servicer or the related Subservicer, as the case may be, shall be entitled to approve a request from a Mortgagor for a partial release of the related Mortgaged Property, the granting of an easement thereon in favor of another Person, any alteration or demolition of the related Mortgaged Property or other similar matters if it has determined, exercising its good faith business judgment in the same manner as it would if it were the owner of the related Mortgage Loan, that the security for, and the timely and full collectability of, such Mortgage Loan would not be adversely affected thereby and that any REMIC created hereunder would not fail to continue to qualify as a REMIC under the Code as a result thereof and (subject to Section 10.01(f)) that no tax on “prohibited transactions” or “contributions” after the Startup Date would be imposed on any REMIC created hereunder as a result thereof. Any fee collected by the Master Servicer or the related Subservicer for processing such a request will be retained by the Master Servicer or such Subservicer as additional servicing compensation.

(d) Subject to any other applicable terms and conditions of this Agreement, the Trustee and Master Servicer shall be entitled to approve an assignment in lieu of satisfaction with respect to any Mortgage Loan, provided the obligee with respect to such Mortgage Loan following such proposed assignment provides the Trustee and Master Servicer with a “Lender Certification for Assignment of Mortgage Loan” in the form attached hereto as Exhibit M, in form and substance satisfactory to the Trustee and Master Servicer, providing the following: (i) that the Mortgage Loan is secured by Mortgaged Property located in a jurisdiction in which an assignment in lieu of satisfaction is required to preserve lien priority, minimize or avoid mortgage recording taxes or otherwise comply with, or facilitate a refinancing under, the laws of such jurisdiction; (ii) that the substance of the assignment is, and is intended to be, a refinancing of such Mortgage Loan and that the form of the transaction is solely to comply with, or facilitate the transaction under, such local laws; (iii) that the Mortgage Loan following the proposed assignment will have a rate of interest more than the greater of (A) 3% and (B) 5% of the annual yield of the unmodified Mortgage Loan, below or above the rate of interest on such Mortgage Loan prior to such proposed assignment; and (iv) that such assignment is at the request of the borrower under the related Mortgage Loan. Upon approval of an assignment in lieu of satisfaction with respect to any Mortgage Loan, the Master Servicer shall receive cash in an amount equal to the unpaid principal balance of and accrued interest on such Mortgage Loan, and the Master Servicer shall treat such amount as a Principal Prepayment in Full with respect to such Mortgage Loan for all purposes hereof.

Section 3.14. Realization Upon Defaulted Mortgage Loans.

(a) The Master Servicer shall foreclose upon or otherwise comparably convert (which may include an REO Acquisition) the ownership of properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.07. Alternatively, the Master Servicer may take other actions in respect of a defaulted Mortgage Loan, which may include (i) accepting a short sale (a payoff of the Mortgage Loan for an amount less than the total amount contractually owed in order to facilitate a sale of the Mortgaged Property by the Mortgagor) or permitting a short refinancing (a payoff of the Mortgage Loan for an amount less than the total amount contractually owed in order to facilitate refinancing transactions by the Mortgagor not involving a sale of the Mortgaged Property), (ii) arranging for a repayment plan or (iii) agreeing to a modification in accordance with Section 3.07. In connection with such foreclosure or other conversion or action, the Master Servicer shall, consistent with Section 3.11, follow such practices and procedures as it shall deem necessary or advisable, as shall be normal and usual in its general mortgage servicing activities and as shall be required or permitted by the Program Guide; provided that the Master Servicer shall not be liable in any respect hereunder if the Master Servicer is acting in connection with any such foreclosure or other conversion or action in a manner that is consistent with the provisions of this Agreement. The Master Servicer, however, shall not be required to expend its own funds or incur other reimbursable charges in connection with any foreclosure, or attempted foreclosure which is not completed, or towards the correction of any default on a related senior mortgage loan, or towards the restoration of any property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the Mortgage Loan to Holders of Certificates of one or more Classes after reimbursement to itself for such expenses or charges and (ii) that such expenses and charges will be recoverable to it through Liquidation Proceeds, Insurance Proceeds, or REO Proceeds (respecting which it shall have priority for purposes of withdrawals from the Custodial Account pursuant to Section 3.10, whether or not such expenses and charges are actually recoverable from related Liquidation Proceeds, Insurance Proceeds or REO Proceeds). In the event of such a determination by the Master Servicer pursuant to this Section 3.14(a), the Master Servicer shall be entitled to reimbursement of its funds so expended pursuant to Section 3.10. In addition, the Master Servicer may pursue any remedies that may be available in connection with a breach of a representation and warranty with respect to any such Mortgage Loan in accordance with Sections 2.03 and 2.04. However, the Master Servicer is not required to continue to pursue both foreclosure (or similar remedies) with respect to the Mortgage Loans and remedies in connection with a breach of a representation and warranty if the Master Servicer determines in its reasonable discretion that one such remedy is more likely to result in a greater recovery as to the Mortgage Loan. Upon the occurrence of a Cash Liquidation or REO Disposition, following the deposit in the Custodial Account of all Insurance Proceeds, Liquidation Proceeds and other payments and recoveries referred to in the definition of “Cash Liquidation” or “REO Disposition,” as applicable, upon receipt by the Trustee of written notification of such deposit signed by a Servicing Officer, the Trustee or any Custodian, as the case may be, shall release to the Master Servicer the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment prepared by the Master Servicer, in each case without recourse, as shall be necessary to vest in the Master Servicer or its designee, as the case may be, the related Mortgage Loan, and thereafter such Mortgage Loan shall not be part of the Trust Fund. Notwithstanding the foregoing or any other provision of this Agreement, in the Master Servicer’s sole discretion with respect to any defaulted Mortgage Loan or REO Property as to either of the following provisions, (i) a Cash Liquidation or REO Disposition may be deemed to have occurred if substantially all amounts expected by the Master Servicer to be received in connection with the related defaulted Mortgage Loan or REO Property have been received, and (ii) for purposes of determining the amount of any Liquidation Proceeds, Insurance Proceeds, REO Proceeds or other unscheduled collections or the amount of any Realized Loss, the Master Servicer may take into account minimal amounts of additional receipts expected to be received or any estimated additional liquidation expenses expected to be incurred in connection with the related defaulted Mortgage Loan or REO Property.

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

(c) In the event that the Trust Fund acquires any REO Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the Master Servicer on behalf of the Trust Fund shall dispose of such REO Property as soon as practicable, giving due consideration to the interests of the Certificateholders, but in all cases, within three full years after the taxable year of its acquisition by the Trust Fund for purposes of Section 860G(a)(8) of the Code (or such shorter period as may be necessary under applicable state (including any state in which such property is located) law to maintain the status of each REMIC created hereunder as a REMIC under applicable state law and avoid taxes resulting from such property failing to be foreclosure property under applicable state law) or, at the expense of the Trust Fund, request, more than 60 days before the day on which such grace period would otherwise expire, an extension of such grace period unless the Master Servicer (subject to Section 10.01(f)) obtains for the Trustee an Opinion of Counsel, addressed to the Trustee and the Master Servicer, to the effect that the holding by the Trust Fund of such REO Property subsequent to such period will not result in the imposition of taxes on “prohibited transactions” as defined in Section 860F of the Code or cause any REMIC created hereunder to fail to qualify as a REMIC (for federal (or any applicable State or local) income tax purposes) at any time that any Certificates are outstanding, in which case the Trust Fund may continue to hold such REO Property (subject to any conditions contained in such Opinion of Counsel). The Master Servicer shall be entitled to be reimbursed from the Custodial Account for any costs incurred in obtaining such Opinion of Counsel, as provided in Section 3.10. Notwithstanding any other provision of this Agreement, no REO Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or (ii) subject any REMIC created hereunder to the imposition of any federal income taxes on the income earned from such REO Property, including any taxes imposed by reason of Section 860G(c) of the Code, unless the Master Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

(d) The proceeds of any Cash Liquidation, REO Disposition or purchase or repurchase of any Mortgage Loan pursuant to the terms of this Agreement, as well as any recovery (other than Subsequent Recoveries) resulting from a collection of Liquidation Proceeds, Insurance Proceeds or REO Proceeds, will be applied in the following order of priority: first, to reimburse the Master Servicer or the related Subservicer in accordance with Section 3.10(a)(ii); second, to the Certificateholders to the extent of accrued and unpaid interest on the Mortgage Loan, and any related REO Imputed Interest, at the Net Mortgage Rate (or the Modified Net Mortgage Rate in the case of a Modified Mortgage Loan), to the Due Date in the related Due Period prior to the Distribution Date on which such amounts are to be distributed; third, to the Certificateholders as a recovery of principal on the Mortgage Loan (or REO Property); fourth, to all Servicing Fees and Subservicing Fees payable therefrom (and the Master Servicer and the Subservicer shall have no claims for any deficiencies with respect to such fees which result from the foregoing allocation); and fifth, to Foreclosure Profits.

(e) In the event of a default on a Mortgage Loan one or more of whose obligors is not a United States Person, in connection with any foreclosure or acquisition of a deed in lieu of foreclosure (together, “foreclosure”) in respect of such Mortgage Loan, the Master Servicer shall cause compliance with the provisions of Treasury Regulation Section 1.1445-2(d)(3) (or any successor thereto) necessary to assure that no withholding tax obligation arises with respect to the proceeds of such foreclosure except to the extent, if any, that proceeds of such foreclosure are required to be remitted to the obligors on such Mortgage Loan.

Section 3.15. Trustee to Cooperate; Release of Mortgage Files.

(a) Upon becoming aware of the payment in full of any Mortgage Loan, or upon the receipt by the Master Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, the Master Servicer shall immediately notify the Trustee (if it holds the related Mortgage File) or the Custodian by a certification of a Servicing Officer (which certification shall include a statement to the effect that all amounts received or to be received in connection with such payment which are required to be deposited in the Custodial Account pursuant to Section 3.07 have been or will be so deposited), substantially in the form attached hereto as Exhibit G, or, in the case of a Custodian, an electronic request in a form acceptable to the Custodian, requesting delivery to it of the Mortgage File. Upon receipt of such certification and request, the Trustee shall promptly release, or cause the Custodian to release, the related Mortgage File to the Master Servicer. The Master Servicer is authorized to execute and deliver to the Mortgagor the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage, together with the Mortgage Note with, as appropriate, written evidence of cancellation thereon and to cause the removal from the registration on the MERS® System of such Mortgage and to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of satisfaction or cancellation or of partial or full release, including any applicable UCC termination statements. No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Custodial Account or the Certificate Account.

(b) From time to time as is appropriate for the servicing or foreclosure of any Mortgage Loan, the Master Servicer shall deliver to the Custodian, with a copy to the Trustee, a certificate of a Servicing Officer substantially in the form attached as Exhibit G hereto, or, in the case of a Custodian, an electronic request in a form acceptable to the Custodian, requesting that possession of all, or any document constituting part of, the Mortgage File be released to the Master 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 Required Insurance Policy. Upon receipt of the foregoing, the Trustee shall deliver, or cause the Custodian to deliver, the Mortgage File or any document therein to the Master Servicer. The Master Servicer shall cause each Mortgage File or any document therein so released to be returned to the Trustee, or the Custodian as agent for the Trustee when the need therefor by the Master Servicer no longer exists, unless (i) the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Custodial Account or (ii) the Mortgage File or such document has been delivered directly or through a Subservicer 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 Master Servicer has delivered directly or through a Subservicer to the Trustee 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. In the event of the liquidation of a Mortgage Loan, the Trustee shall deliver the Request for Release with respect thereto to the Master Servicer upon the Trustee’s receipt of notification from the Master Servicer of the deposit of the related Liquidation Proceeds in the Custodial Account.

(c) The Trustee or the Master Servicer on the Trustee’s behalf shall execute and deliver to the Master Servicer, if necessary, any court pleadings, requests for trustee’s sale or other documents necessary to the foreclosure or trustee’s sale in respect of a Mortgaged Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage Note or Mortgage or otherwise available at law or in equity. Together with such documents or pleadings (if signed by the Trustee), the Master Servicer shall deliver to the Trustee a certificate of a Servicing Officer requesting that such pleadings or documents be executed by the Trustee and certifying as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee shall not invalidate any insurance coverage under any Required Insurance Policy or invalidate or otherwise affect the lien of the Mortgage, except for the termination of such a lien upon completion of the foreclosure or trustee’s sale.

Section 3.16. Servicing and Other Compensation; Compensating Interest.

(a) The Master Servicer, as compensation for its activities hereunder, shall be entitled to receive on each Distribution Date the amounts provided for by clauses (iii), (iv), (v) and (vi) of Section 3.10(a), subject to clause (e) below. The amount of servicing compensation provided for in such clauses shall be accounted for on a Mortgage Loan-by-Mortgage Loan basis. In the event that Liquidation Proceeds, Insurance Proceeds and REO Proceeds (net of amounts reimbursable therefrom pursuant to Section 3.10(a)(ii)) in respect of a Cash Liquidation or REO Disposition exceed the unpaid principal balance of such Mortgage Loan plus unpaid interest accrued thereon (including REO Imputed Interest) at a per annum rate equal to the related Net Mortgage Rate (or the Modified Net Mortgage Rate in the case of a Modified Mortgage Loan), the Master Servicer shall be entitled to retain therefrom and to pay to itself and/or the related Subservicer, any Foreclosure Profits and any Servicing Fee or Subservicing Fee considered to be accrued but unpaid.

(b) Additional servicing compensation in the form of assumption fees, late payment charges, investment income on amounts in the Custodial Account or the Certificate Account or otherwise shall be retained by the Master Servicer or the Subservicer to the extent provided herein, subject to clause (e) below. Prepayment charges shall be deposited into the Certificate Account and shall be paid on each Distribution Date to the holders of the Class SB Certificates.

(c) The Master Servicer shall be required to pay, or cause to be paid, all expenses incurred by it in connection with its servicing activities hereunder (including payment of premiums for the Primary Insurance Policies, if any, to the extent such premiums are not required to be paid by the related Mortgagors, and the fees and expenses of the Trustee and any Custodian) and shall not be entitled to reimbursement therefor except as specifically provided in Sections 3.10 and 3.14.

(d) The Master Servicer’s right to receive servicing compensation may not be transferred in whole or in part except in connection with the transfer of all of its responsibilities and obligations of the Master Servicer under this Agreement.

(e) Notwithstanding clauses (a) and (b) above, the amount of servicing compensation that the Master Servicer shall be entitled to receive for its activities hereunder for the period ending on each Distribution Date shall be reduced (but not below zero) by the amount of Compensating Interest (if any) for such Distribution Date used to cover Prepayment Interest Shortfalls as provided in Section 3.16(f) below. Such reduction shall be applied during such period as follows: first, to any Servicing Fee or Subservicing Fee to which the Master Servicer is entitled pursuant to Section 3.10(a)(iii); and second, to any income or gain realized from any investment of funds held in the Custodial Account or the Certificate Account to which the Master Servicer is entitled pursuant to Sections 3.07(c) or 4.01(c), respectively. In making such reduction, the Master Servicer shall not withdraw from the Custodial Account any such amount representing all or a portion of the Servicing Fee to which it is entitled pursuant to Section 3.10(a)(iii) and shall not withdraw from the Custodial Account or Certificate Account any such amount to which it is entitled pursuant to Section 3.07(c) or 4.01(c).

(f) With respect to any Distribution Date, Prepayment Interest Shortfalls on the Mortgage Loans will be covered first, by the Master Servicer, but only to the extent such Prepayment Interest Shortfalls do not exceed Eligible Master Servicing Compensation.

Section 3.17. Reports to the Trustee and the Depositor.

Not later than fifteen days after each Distribution Date, the Master Servicer shall forward to the Trustee and the Depositor a statement, certified by a Servicing Officer, setting forth the status of the Custodial Account as of the close of business on such Distribution Date as it relates to the Mortgage Loans and showing, for the period covered by such statement, the aggregate of deposits in or withdrawals from the Custodial Account in respect of the Mortgage Loans for each category of deposit specified in Section 3.07 and each category of withdrawal specified in Section 3.10.

Section 3.18. Annual Statement as to Compliance.

The Master Servicer shall deliver to the Depositor and the Trustee on or before the earlier of (a) March 31 of each year, beginning with the first March 31 that occurs at least six months after the Cut-off Date or (b) with respect to any calendar year during which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission, on or before the date on which the annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission, an Officers’ Certificate stating, as to each signer thereof, that (i) a review of the activities of the Master Servicer during the preceding calendar year related to its servicing of mortgage loans and of its performance under the pooling and servicing agreements, including this Agreement, has been made under such officers’ supervision, (ii) to the best of such officers’ knowledge, based on such review, the Master Servicer has complied in all material respects with the minimum servicing standards set forth in the Uniform Single Attestation Program for Mortgage Bankers and has fulfilled all of its material obligations relating to this Agreement in all material respects throughout such year, or, if there has been material noncompliance with such servicing standards or a default in the fulfillment in all material respects of any such obligation relating to this Agreement, such statement shall include a description of such noncompliance or specify each such default, as the case may be, known to such officer and the nature and status thereof and (iii) to the best of such officers’ knowledge, each Subservicer has complied in all material respects with the minimum servicing standards set forth in the Uniform Single Attestation Program for Mortgage Bankers and has fulfilled all of its material obligations under its Subservicing Agreement in all material respects throughout such year, or, if there has been material noncompliance with such servicing standards or a material default in the fulfillment of such obligations relating to this Agreement, such statement shall include a description of such noncompliance or specify each such default, as the case may be, known to such officer and the nature and status thereof.

Section 3.19. Annual Independent Public Accountants' Servicing Report.

On or before the earlier of (a) March 31 of each year, beginning with the first March 31 that occurs at least six months after the Cut-off Date, or (b) with respect to any calendar year during which the Depositor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission, on or before the date on which the annual report is required to be filed in accordance with the Exchange Act and the rules and regulations of the Commission, the Master Servicer at its expense shall cause a firm of independent public accountants, which shall be members of the American Institute of Certified Public Accountants, to furnish a report to the Depositor and the Trustee stating its opinion that, on the basis of an examination conducted by such firm substantially in accordance with standards established by the American Institute of Certified Public Accountants, the assertions made pursuant to Section 3.18 regarding compliance with the minimum servicing standards set forth in the Uniform Single Attestation Program for Mortgage Bankers during the preceding calendar year are fairly stated in all material respects, subject to such exceptions and other qualifications that, in the opinion of such firm, such accounting standards require it to report. In rendering such statement, such firm may rely, as to matters relating to the direct servicing of mortgage loans by Subservicers, upon comparable statements for examinations conducted by independent public accountants substantially in accordance with standards established by the American Institute of Certified Public Accountants (rendered within one year of such statement) with respect to such Subservicers. In the event such firm requires the Trustee to agree to the procedures performed by such firm, the Master Servicer shall direct the Trustee in writing to so agree; it being understood and agreed that the Trustee shall deliver such letter of agreement in conclusive reliance upon the direction of the Master Servicer, and the Trustee shall not make any independent inquiry or investigation as to, and shall have no obligation or liability in respect of, the sufficiency, validity or correctness of such procedures.

Section 3.20. Right of the Depositor in Respect of the Master Servicer.

The Master Servicer shall afford the Depositor and the Trustee, upon reasonable notice, during normal business hours access to all records maintained by the Master Servicer in respect of its rights and obligations hereunder and access to officers of the Master Servicer responsible for such obligations. Upon request, the Master Servicer shall furnish the Depositor with its most recent financial statements and such other information as the Master Servicer possesses regarding its business, affairs, property and condition, financial or otherwise.

The Depositor may enforce the obligation of the Master Servicer hereunder and may, but it is not obligated to, perform or cause a designee to perform, any defaulted obligation of the Master Servicer hereunder or exercise the rights of the Master Servicer hereunder; provided that the Master Servicer shall not be relieved of any of its obligations hereunder by virtue of such performance by the Depositor or its designee. Neither the Depositor nor the Trustee shall have the responsibility or liability for any action or failure to act by the Master Servicer and the Depositor is not obligated to supervise the performance of the Master Servicer under this Agreement or otherwise.

Section 3.21. [Reserved].

Section 3.22. Advance Facility.

(a) The Master Servicer is hereby authorized to enter into a financing or other facility (any such arrangement, an “Advance Facility”) under which (1) the Master Servicer sells, assigns or pledges to another Person (an “Advancing Person”) the Master Servicer’s rights under this Agreement to be reimbursed for any Advances or Servicing Advances and/or (2) an Advancing Person agrees to fund some or all Advances and/or Servicing Advances required to be made by the Master Servicer pursuant to this Agreement. No consent of the Depositor, the Trustee, the Certificateholders or any other party shall be required before the Master Servicer may enter into an Advance Facility. Notwithstanding the existence of any Advance Facility under which an Advancing Person agrees to fund Advances and/or Servicing Advances on the Master Servicer’s behalf, the Master Servicer shall remain obligated pursuant to this Agreement to make Advances and Servicing Advances pursuant to and as required by this Agreement. If the Master Servicer enters into an Advance Facility, and for so long as an Advancing Person remains entitled to receive reimbursement for any Advances including Nonrecoverable Advances (“Advance Reimbursement Amounts”) and/or Servicing Advances including Nonrecoverable Advances (“Servicing Advance Reimbursement Amounts” and together with Advance Reimbursement Amounts, “Reimbursement Amounts”) (in each case to the extent such type of Reimbursement Amount is included in the Advance Facility), as applicable, pursuant to this Agreement, then the Master Servicer shall identify such Reimbursement Amounts consistent with the reimbursement rights set forth in Section 3.10(a)(ii) and (vii) and remit such Reimbursement Amounts in accordance with this Section 3.22 or otherwise in accordance with the documentation establishing the Advance Facility to such Advancing Person or to a trustee, agent or custodian (an “Advance Facility Trustee”) designated by such Advancing Person in an Advance Facility Notice described below in Section 3.22(b). Notwithstanding the foregoing, if so required pursuant to the terms of the Advance Facility, the Master Servicer may direct, and if so directed in writing, the Trustee is hereby authorized to and shall pay to the Advance Facility Trustee the Reimbursement Amounts identified pursuant to the preceding sentence. An Advancing Person whose obligations hereunder are limited to the funding of Advances and/or Servicing Advances shall not be required to meet the qualifications of a Master Servicer or a Subservicer pursuant to Section 3.02(a) or 6.02(c) hereof and shall not be deemed to be a Subservicer under this Agreement. Notwithstanding anything to the contrary herein, in no event shall Advance Reimbursement Amounts or Servicing Advance Reimbursement Amounts be included in the Available Distribution Amount or distributed to Certificateholders.

(b) If the Master Servicer enters into an Advance Facility and makes the election set forth in Section 3.22(a), the Master Servicer and the related Advancing Person shall deliver to the Trustee a written notice and payment instruction (an “Advance Facility Notice”), providing the Trustee with written payment instructions as to where to remit Advance Reimbursement Amounts and/or Servicing Advance Reimbursement Amounts (each to the extent such type of Reimbursement Amount is included within the Advance Facility) on subsequent Distribution Dates. The payment instruction shall require the applicable Reimbursement Amounts to be distributed to the Advancing Person or to an Advance Facility Trustee designated in the Advance Facility Notice. An Advance Facility Notice may only be terminated by the joint written direction of the Master Servicer and the related Advancing Person (and any related Advance Facility Trustee).

(c) Reimbursement Amounts shall consist solely of amounts in respect of Advances and/or Servicing Advances made with respect to the Mortgage Loans for which the Master Servicer would be permitted to reimburse itself in accordance with Section 3.10(a)(ii) and (vii) hereof, assuming the Master Servicer or the Advancing Person had made the related Advance(s) and/or Servicing Advance(s). Notwithstanding the foregoing, except with respect to reimbursement of Nonrecoverable Advances as set forth in Section 3.10(c) of this Agreement, no Person shall be entitled to reimbursement from funds held in the Collection Account for future distribution to Certificateholders pursuant to this Agreement. Neither the Depositor nor the Trustee shall have any duty or liability with respect to the calculation of any Reimbursement Amount, nor shall the Depositor or the Trustee have any responsibility to track or monitor the administration of the Advance Facility and the Depositor shall not have any responsibility to track, monitor or verify the payment of Reimbursement Amounts to the related Advancing Person or Advance Facility Trustee. The Master Servicer shall maintain and provide to any successor master servicer a detailed accounting on a loan-by-loan basis as to amounts advanced by, sold, pledged or assigned to, and reimbursed to any Advancing Person. The successor master servicer shall be entitled to rely on any such information provided by the Master Servicer, and the successor master servicer shall not be liable for any errors in such information.

(d) Upon the direction of and at the expense of the Master Servicer, the Trustee agrees to execute such acknowledgments, certificates, and other documents reasonably satisfactory to the Trustee provided by the Master Servicer and reasonable satisfactory to the Trustee recognizing the interests of any Advancing Person or Advance Facility Trustee in such Reimbursement Amounts as the Master Servicer may cause to be made subject to Advance Facilities pursuant to this Section 3.22, and such other documents in connection with such Advance Facility as may be reasonably requested from time to time by any Advancing Person or Advance Facility Trustee and reasonably satisfactory to the Trustee.

(e) Reimbursement Amounts collected with respect to each Mortgage Loan shall be allocated to outstanding unreimbursed Advances or Servicing Advances (as the case may be) made with respect to that Mortgage Loan on a “first-in, first out” (“FIFO”) basis, subject to the qualifications set forth below:

(i) Any successor Master Servicer to Residential Funding (a “Successor Master Servicer”) and the Advancing Person or Advance Facility Trustee shall be required to apply all amounts available in accordance with this Section 3.22(e) to the reimbursement of Advances and Servicing Advances in the manner provided for herein; provided, however, that after the succession of a Successor Master Servicer, (A) to the extent that any Advances or Servicing Advances with respect to any particular Mortgage Loan are reimbursed from payments or recoveries, if any, from the related Mortgagor, and Liquidation Proceeds or Insurance Proceeds, if any, with respect to that Mortgage Loan, reimbursement shall be made, first, to the Advancing Person or Advance Facility Trustee in respect of Advances and/or Servicing Advances related to that Mortgage Loan to the extent of the interest of the Advancing Person or Advance Facility Trustee in such Advances and/or Servicing Advances, second to the Master Servicer in respect of Advances and/or Servicing Advances related to that Mortgage Loan in excess of those in which the Advancing Person or Advance Facility Trustee Person has an interest, and third, to the Successor Master Servicer in respect of any other Advances and/or Servicing Advances related to that Mortgage Loan, from such sources as and when collected, and (B) reimbursements of Advances and Servicing Advances that are Nonrecoverable Advances shall be made pro rata to the Advancing Person or Advance Facility Trustee, on the one hand, and any such Successor Master Servicer, on the other hand, on the basis of the respective aggregate outstanding unreimbursed Advances and Servicing Advances that are Nonrecoverable Advances owed to the Advancing Person, Advance Facility Trustee or Master Servicer pursuant to this Agreement, on the one hand, and any such Successor Master Servicer, on the other hand, and without regard to the date on which any such Advances or Servicing Advances shall have been made. In the event that, as a result of the FIFO allocation made pursuant to this Section 3.22(e), some or all of a Reimbursement Amount paid to the Advancing Person or Advance Facility Trustee relates to Advances or Servicing Advances that were made by a Person other than Residential Funding or the Advancing Person or Advance Facility Trustee, then the Advancing Person or Advance Facility Trustee shall be required to remit any portion of such Reimbursement Amount to the Person entitled to such portion of such Reimbursement Amount. Without limiting the generality of the foregoing, Residential Funding shall remain entitled to be reimbursed by the Advancing Person or Advance Facility Trustee for all Advances and Servicing Advances funded by Residential Funding to the extent the related Reimbursement Amount(s) have not been assigned or pledged to an Advancing Person or Advance Facility Trustee. The documentation establishing any Advance Facility shall require Residential Funding to provide to the related Advancing Person or Advance Facility Trustee loan by loan information with respect to each Reimbursement Amount distributed to such Advancing Person or Advance Facility Trustee on each date of remittance thereof to such Advancing Person or Advance Facility Trustee, to enable the Advancing Person or Advance Facility Trustee to make the FIFO allocation of each Reimbursement Amount with respect to each Mortgage Loan.

(ii) By way of illustration, and not by way of limiting the generality of the foregoing, if the Master Servicer resigns or is terminated at a time when the Master Servicer is a party to an Advance Facility, and is replaced by a Successor Master Servicer, and the Successor Master Servicer directly funds Advances or Servicing Advances with respect to a Mortgage Loan and does not assign or pledge the related Reimbursement Amounts to the related Advancing Person or Advance Facility Trustee, then all payments and recoveries received from the related Mortgagor or received in the form of Liquidation Proceeds with respect to such Mortgage Loan (including Insurance Proceeds collected in connection with a liquidation of such Mortgage Loan) will be allocated first to the Advancing Person or Advance Facility Trustee until the related Reimbursement Amounts attributable to such Mortgage Loan that are owed to the Master Servicer and the Advancing Person, which were made prior to any Advances or Servicing Advances made by the Successor Master Servicer, have been reimbursed in full, at which point the Successor Master Servicer shall be entitled to retain all related Reimbursement Amounts subsequently collected with respect to that Mortgage Loan pursuant to Section 3.10 of this Agreement. To the extent that the Advances or Servicing Advances are Nonrecoverable Advances to be reimbursed on an aggregate basis pursuant to Section 3.10 of this Agreement, the reimbursement paid in this manner will be made pro rata to the Advancing Person or Advance Facility Trustee, on the one hand, and the Successor Master Servicer, on the other hand, as described in clause (i)(B) above.

(f) The Master Servicer shall remain entitled to be reimbursed for all Advances and Servicing Advances funded by the Master Servicer to the extent the related rights to be reimbursed therefor have not been sold, assigned or pledged to an Advancing Person.

(g) Any amendment to this Section 3.22 or to any other provision of this Agreement that may be necessary or appropriate to effect the terms of an Advance Facility as described generally in this Section 3.22, including amendments to add provisions relating to a successor master servicer, may be entered into by the Trustee, the Depositor and the Master Servicer without the consent of any Certificateholder, with written confirmation from each Rating Agency that the amendment will not result in the reduction of the ratings on any class of the Certificates below the lesser of the then current or original ratings on such Certificates and delivery of an Opinion of Counsel as required under Section 11.01(c), notwithstanding anything to the contrary in Section 11.01 of or elsewhere in this Agreement.

(h) Any rights of set-off that the Trust Fund, the Trustee, the Depositor, any Successor Master Servicer or any other Person might otherwise have against the Master Servicer under this Agreement shall not attach to any rights to be reimbursed for Advances or Servicing Advances that have been sold, transferred, pledged, conveyed or assigned to any Advancing Person.

(i) At any time when an Advancing Person shall have ceased funding Advances and/or Servicing Advances (as the case may be) and the Advancing Person or related Advance Facility Trustee shall have received Reimbursement Amounts sufficient in the aggregate to reimburse all Advances and/or Servicing Advances (as the case may be) the right to reimbursement for which were assigned to the Advancing Person, then upon the delivery of a written notice signed by the Advancing Person and the Master Servicer or its successor or assign) to the Trustee terminating the Advance Facility Notice (the “Notice of Facility Termination”), the Master Servicer or its Successor Master Servicer shall again be entitled to withdraw and retain the related Reimbursement Amounts from the Custodial Account pursuant to Section 3.10.

(j) After delivery of any Advance Facility Notice, and until any such Advance Facility Notice has been terminated by a Notice of Facility Termination, this Section 3.22 may not be amended or otherwise modified without the prior written consent of the related Advancing Person.

New York time on each Certificate Account Deposit Date, the Master Servicer shall either (i) remit to the Trustee for deposit in the Certificate Account from its own funds, or funds received therefor from the Subservicers, an amount equal to the Advances to be made by the Master Servicer in respect of the related Distribution Date, which shall be in an aggregate amount equal to the sum of (A) the aggregate amount of Monthly Payments other than Balloon Payments (with each interest portion thereof adjusted to a per annum rate equal to the Net Mortgage Rate), less the amount of any related Servicing Modifications, Debt Service Reductions or Relief Act Shortfalls, on the Outstanding Mortgage Loans as of the related Due Date in the related Due Period, which Monthly Payments were due during the related Due Period and not received as of the close of business as of the related Determination Date; provided that no Advance shall be made if it would be a Nonrecoverable Advance and (B) with respect to each Balloon Loan delinquent in respect of its Balloon Payment as of the close of business on the related Determination Date, an amount equal to the assumed Monthly Payment (with each interest portion thereof adjusted to a per annum rate equal to the Net Mortgage Rate) that would have been due on the related Due Date based on the original amortization schedule for such Balloon Loan until such Balloon Loan is finally liquidated, over any payments of interest or principal (with each interest portion thereof adjusted to a per annum rate equal to the Net Mortgage Rate) received from the related Mortgagor as of the close of business on the related Determination Date and allocable to the Due Date during the related Due Period for each month until such Balloon Loan is finally liquidated, (ii) withdraw from amounts on deposit in the Custodial Account and remit to the Trustee for deposit in the Certificate Account all or a portion of the Amount Held for Future Distribution in discharge of any such Advance, or (iii) make advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any portion of the Amount Held for Future Distribution so used shall be replaced by the Master Servicer by deposit in the Certificate Account on or before 11:00 A.M. New York time on any future Certificate Account Deposit Date to the extent that funds attributable to the Mortgage Loans that are available in the Custodial Account for deposit in the Certificate Account on such Certificate Account Deposit Date shall be less than payments to Certificateholders required to be made on the following Distribution Date. The Master Servicer shall be entitled to use any Advance made by a Subservicer as described in Section 3.07(b) that has been deposited in the Custodial Account on or before such Distribution Date as part of the Advance made by the Master Servicer pursuant to this Section 4.04. The determination by the Master Servicer that it has made a Nonrecoverable Advance or that any proposed Advance, if made, would constitute a Nonrecoverable Advance, shall be evidenced by a certificate of a Servicing Officer delivered to the Depositor and the Trustee. In the event that the Master Servicer determines as of the Business Day preceding any Certificate Account Deposit Date that it will be unable to deposit in the Certificate Account an amount equal to the Advance required to be made for the immediately succeeding Distribution Date, it shall give notice to the Trustee of its inability to advance (such notice may be given by telecopy), not later than 3:00 P.M., New York time, on such Business Day, specifying the portion of such amount that it will be unable to deposit. Not later than 3:00 P.M., New York time, on the Certificate Account Deposit Date the Trustee shall, unless by 12:00 Noon, New York time, on such day the Trustee shall have been notified in writing (by telecopy) that the Master Servicer shall have directly or indirectly deposited in the Certificate Account such portion of the amount of the Advance as to which the Master Servicer shall have given notice pursuant to the preceding sentence, pursuant to Section 7.01, (a) terminate all of the rights and obligations of the Master Servicer under this Agreement in accordance with Section 7.01 and (b) assume the rights and obligations of the Master Servicer hereunder, including the obligation to deposit in the Certificate Account an amount equal to the Advance for the immediately succeeding Distribution Date. The Trustee shall deposit all funds it receives pursuant to this Section 4.04(b) into the Certificate Account.

Section 4.05. Allocation of Realized Losses.

(a)

Prior to each Distribution Date, the Master Servicer shall determine the total amount of Realized Losses, if any, that resulted from any Cash Liquidation, Servicing Modifications, Debt Service Reduction, Deficient Valuation or REO Disposition that occurred during the related Prepayment Period or, in the case of a Servicing Modification that constitutes a reduction of the interest rate on a Mortgage Loan, the amount of the reduction in the interest portion of the Monthly Payment due in the month in which such Distribution Date occurs. The amount of each Realized Loss shall be evidenced by an Officers’ Certificate.

(b)

All Realized Losses on the Mortgage Loans shall be allocated as follows:

(i)

first, to Excess Cash Flow in the amounts and priority as provided in Section 4.02;

(ii)

second, in reduction of the Overcollateralization Amount, until such amount has been reduced to zero;

(iii)

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

(iv)

fourth, to the Class B-1 Certificates, until the aggregate Certificate Principal Balance thereof has been reduced to zero;

(v)

fifth, to the Class M-7 Certificates, until the aggregate Certificate Principal Balance thereof has been reduced to zero;

(vi)

sixth, to the Class M-6 Certificates, until the aggregate Certificate Principal Balance thereof has been reduced to zero;

(vii)

seventh, to the Class M-5 Certificates, until the aggregate Certificate Principal Balance thereof has been reduced to zero;

(viii)

eighth, to the Class M-4 Certificates, until the aggregate Certificate Principal Balance thereof has been reduced to zero;

(ix)

ninth, to the Class M-3 Certificates, until the aggregate Certificate Principal Balance thereof has been reduced to zero;

(x)

tenth, to the Class M-2 Certificates, until the aggregate Certificate Principal Balance thereof has been reduced to zero;

(xi)

eleventh, to the Class M-1 Certificates, until the aggregate Certificate Principal Balance thereof has been reduced to zero;

(xii)

twelfth, to the Class A-4A Certificates and Class A-4B Certificates on a pro rata basis, until the aggregate Certificate Principal Balance of each such Class has been reduced to zero; and

(xiii)

thirteenth, to the Class A-1, Class A-2 and Class A-3 Certificates on a pro rata basis, until the aggregate Certificate Principal Balance of each such Class has been reduced to zero.

(c)

An allocation of a Realized Loss on a “pro rata basis” among two or more specified Classes of Certificates means an allocation on a pro rata basis, among the various Classes so specified, to each such Class of Certificates on the basis of their then outstanding Certificate Principal Balances prior to giving effect to distributions to be made on such Distribution Date in the case of the principal portion of a Realized Loss or based on the Accrued Certificate Interest thereon payable on such Distribution Date in the case of an interest portion of a Realized Loss. Any allocation of the principal portion of Realized Losses (other than Debt Service Reductions) to the Class A Certificates, Class M Certificates or Class B Certificates shall be made by reducing the Certificate Principal Balance thereof by the amount so allocated, which allocation shall be deemed to have occurred on such Distribution Date; provided, that no such reduction shall reduce the aggregate Certificate Principal Balance of the Certificates below the aggregate Stated Principal Balance of the Mortgage Loans. Allocations of the interest portions of Realized Losses (other than any interest rate reduction resulting from a Servicing Modification) shall be made by operation of the definition of “Accrued Certificate Interest” for each Class for such Distribution Date. Allocations of the interest portion of a Realized Loss resulting from an interest rate reduction in connection with a Servicing Modification shall be made by operation of the priority of payment provisions of Section 4.02(c). Allocations of the principal portion of Debt Service Reductions shall be made by operation of the priority of payment provisions of Section 4.02(c). All Realized Losses and all other losses allocated to a Class of Certificates hereunder will be allocated among the Certificates of such Class in proportion to the Percentage Interests evidenced thereby.

(d)

All Realized Losses on the Mortgage Loans shall be allocated on each Distribution Date to the REMIC I Regular Interests as provided in the definition of REMIC I Realized Losses.

(e)

Realized Losses allocated to the Excess Cash Flow or the Overcollateralization Amount pursuant to paragraphs (a), (b) or (c) of this Section, the definition of Accrued Certificate Interest and the operation of Section 4.02(c) shall be deemed allocated to the Class SB Certificates. Realized Losses allocated to the Class SB Certificates shall, to the extent such Realized Losses represent Realized Losses on an interest portion, be allocated to the REMIC II Regular Interest SB-IO. Realized Losses allocated to the Excess Cash Flow pursuant to paragraph (b) of this Section shall be deemed to reduce Accrued Certificate Interest on the REMIC I Regular Interest SB-IO. Realized Losses allocated to the Overcollateralization Amount pursuant to paragraph (b) of this Section shall be deemed first to reduce the principal balance of the REMIC II Regular Interest SB-PO until such principal balance shall have been reduced to zero and thereafter to reduce accrued and unpaid interest on the REMIC II Regular Interest SB-IO.

Section 4.06. Reports of Foreclosures and Abandonment of Mortgaged Property.

The Master Servicer or the Subservicers shall file information returns with respect to the receipt of mortgage interest received in a trade or business, the reports of foreclosures and abandonments of any Mortgaged Property and the informational returns relating to cancellation of indebtedness income with respect to any Mortgaged Property required by Sections 6050H, 6050J and 6050P of the Code, respectively, and deliver to the Trustee an Officers’ Certificate on or before March 31 of each year, beginning with the first March 31 that occurs at least six months after the Cut-off Date, stating that such reports have been filed. Such reports shall be in form and substance sufficient to meet the reporting requirements imposed by such Sections 6050H, 6050J and 6050P of the Code.

Section 4.07. Optional Purchase of Defaulted Mortgage Loans.

(a) With respect to any Mortgage Loan which is delinquent in payment by 90 days or more, the Master Servicer may, at its option, purchase such Mortgage Loan from the Trustee at the Purchase Price therefor; provided, that such Mortgage Loan that becomes 90 days or more delinquent during any given Calendar Quarter shall only be eligible for purchase pursuant to this Section during the period beginning on the first Business Day of the following Calendar Quarter, and ending at the close of business on the second-to-last Business Day of such following Calendar Quarter; and provided, further, that such Mortgage Loan is 90 days or more delinquent at the time of repurchase. Such option if not exercised shall not thereafter be reinstated as to any Mortgage Loan, unless the delinquency is cured and the Mortgage Loan thereafter again becomes delinquent in payment by 90 days or more in a subsequent Calendar Quarter.

(b) If at any time the Master Servicer makes a payment to the Certificate Account covering the amount of the Purchase Price for such a Mortgage Loan as provided in clause (a) above, and the Master Servicer provides to the Trustee a certification signed by a Servicing Officer stating that the amount of such payment has been deposited in the Certificate Account, then the Trustee shall execute the assignment of such Mortgage Loan at the request of the Master Servicer without recourse to the Master Servicer which shall succeed to all the Trustee’s right, title and interest in and to such Mortgage Loan, and all security and documents relative thereto. Such assignment shall be an assignment outright and not for security. The Master Servicer will thereupon own such Mortgage, and all such security and documents, free of any further obligation to the Trustee or the Certificateholders with respect thereto.

Section 4.08. [Reserved].

Section 4.09. [Reserved].

Section 4.10. Hedge Agreements.

(a) In the event that the Trustee does not receive by the Business Day preceding a Distribution Date the amount as specified by the Master Servicer pursuant to Section 4.04(a)(iv) hereof as the amount to be paid with respect to such Distribution Date by the Hedge Agreements Provider under a Hedge Agreement, the Trustee shall enforce the obligation of the Hedge Agreements Provider thereunder. The parties hereto acknowledge that the Hedge Agreements Provider shall be making all calculations, and determine the amounts to be paid, under the Hedge Agreements. Absent manifest error, the Trustee may conclusively rely on such calculations and determination and any notice received by it from the Master Servicer pursuant to Section 4.04(a)(iv) hereof.

(b) The Trustee shall deposit or cause to be deposited any amount received under the Hedge Agreements into the Certificate Account on the date such amount is received from the Hedge Agreements Provider under the Hedge Agreements (including termination payments, if any). All payments received under the Hedge Agreements shall be distributed in accordance with the priorities set forth in Section 4.02(c) hereof.

(c) In the event that a Hedge Agreement, or any replacement thereof, terminates prior to the Distribution Date in February 2007, the Master Servicer, but at no expense to the Master Servicer, on behalf of the Trustee, to the extent that the termination value under such Hedge Agreement is sufficient therefor and only to the extent of the termination payment received from the Hedge Agreements Provider, shall (i) cause a new hedge counterparty to assume the obligations of such terminated hedge counterparty or (ii) cause a new hedge counterparty to enter into a new interest rate hedge agreement with the Trust Fund having substantially similar terms as those set forth in the terminated Hedge Agreement.

ARTICLE V

THE CERTIFICATES

Section 5.01. The Certificates.

(a) The Class A Certificates, Class M Certificates, Class B Certificates, Class SB Certificates and Class R Certificates shall be substantially in the forms set forth in Exhibits A, B, C, D and E, respectively, and shall, on original issue, be executed and delivered by the Trustee to the Certificate Registrar for authentication and delivery to or upon the order of the Depositor upon receipt by the Trustee or one or more Custodians of the documents specified in Section 2.01. Each Class of Class A Certificates and the Class M-1 Certificates shall be issuable in minimum dollar denominations of $25,000 and integral multiples of $1 in excess thereof. The Class M-2 Certificates, Class M-3 Certificates, Class M-4 Certificates, Class M-5 Certificates, Class M-6 Certificates, Class M-7 Certificates, Class B-1 Certificates and Class B-2 Certificates shall be issuable in minimum dollar denominations of $250,000 and integral multiples of $1 in excess thereof. The Class SB Certificates shall be issuable in registered, certificated form in minimum percentage interests of 5.00% and integral multiples of 0.01% in excess thereof. Each Class of Class R Certificates shall be issued in registered, certificated form in minimum percentage interests of 20.00% and integral multiples of 0.01% in excess thereof; provided, however, that one Class R Certificate of each Class will be issuable to the REMIC Administrator as “tax matters person” pursuant to Section 10.01(c) in a minimum denomination representing a Percentage Interest of not less than 0.01%. The Certificates shall be executed by manual or facsimile signature on behalf of an authorized officer of the Trustee. Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Trustee shall bind the Trustee, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificate or did not hold such offices at the date of such Certificates. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided for herein executed by the Certificate Registrar by manual signature, and such certificate upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication.

(b) The Class A Certificates, Class B Certificates and Class M Certificates shall initially be issued as one or more Certificates registered in the name of the Depository or its nominee and, except as provided below, registration of such Certificates may not be transferred by the Trustee except to another Depository that agrees to hold such Certificates for the respective Certificate Owners with Ownership Interests therein. The Certificate Owners shall hold their respective Ownership Interests in and to each Class A Certificate, Class B Certificate and Class M Certificate through the book-entry facilities of the Depository and, except as provided below, shall not be entitled to Definitive Certificates in respect of such Ownership Interests. All transfers by Certificate Owners of their respective Ownership Interests in the Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owner. Each Depository Participant shall transfer the Ownership Interests only in the 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.

The Trustee, the Master Servicer and the Depositor may for all purposes (including the making of payments due on the respective Classes of Book-Entry Certificates) deal with the Depository as the authorized representative of the Certificate Owners with respect to the respective Classes of Book-Entry Certificates for purposes of exercising the rights of Certificateholders hereunder. The rights of Certificate Owners with respect to the respective Classes of Book-Entry Certificates shall be limited to those established by law and agreements between such Certificate Owners and the Depository Participants and brokerage firms representing such Certificate Owners. Multiple requests and directions from, and votes of, the Depository as Holder of any Class of Book-Entry Certificates with respect to any particular matter shall not be deemed inconsistent if they are made with respect to different Certificate Owners. The Trustee may establish a reasonable record date in connection with solicitations of consents from or voting by Certificateholders and shall give notice to the Depository of such record date. If (i)(A) the Depositor advises the Trustee in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository and (B) the Depositor is unable to locate a qualified successor or (ii) the Depositor at its option advises the Trustee in writing that it elects to terminate the book-entry system through the Depository, the Trustee shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of Definitive Certificates to Certificate Owners requesting the same. Upon surrender to the Trustee of the Book-Entry Certificates by the Depository, accompanied by registration instructions from the Depository for registration of transfer, the Trustee shall issue the Definitive Certificates.

In addition, if an Event of Default has occurred and is continuing, each Certificate Owner materially adversely affected thereby may at its option request a Definitive Certificate evidencing such Certificate Owner’s Percentage 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 Percentage 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 Certificate Principal Balance being exchanged, the Depository Participant account to be debited with the decrease, the registered holder of and delivery instructions for the Definitive Certificate, and any other information reasonably required by the Certificate Registrar), (i) the Certificate Registrar shall instruct the Depository to reduce the related Depository Participant’s account by the aggregate Certificate Principal Balance of the Definitive Certificate, (ii) the Trustee shall execute and the Certificate Registrar shall authenticate and deliver, in accordance with the registration and delivery instructions provided by the Depository, a Definitive Certificate evidencing such Certificate Owner’s Percentage Interest in such Class of Certificates and (iii) the Trustee shall execute and the Certificate Registrar shall authenticate a new Book-Entry Certificate reflecting the reduction in the aggregate Certificate Principal Balance of such Class of Certificates by the amount of the Definitive Certificates.

Neither the Depositor, the Master Servicer nor the Trustee shall be liable for any actions taken by the Depository or its nominee, including, without limitation, 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. Upon the issuance of Definitive Certificates, the Trustee and the Master Servicer shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder.

(c) Each of the Certificates is intended to be a “security” governed by Article 8 of the Uniform Commercial Code as in effect in the State of New York and any other applicable jurisdiction, to the extent that any of such laws may be applicable.

Section 5.02. Registration of Transfer and Exchange of Certificates.

(a) The Trustee shall cause to be kept at one of the offices or agencies to be appointed by the Trustee in accordance with the provisions of Section 8.12 a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Trustee shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. The Trustee is initially appointed Certificate Registrar for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided. The Certificate Registrar, or the Trustee, shall provide the Master Servicer with a certified list of Certificateholders as of each Record Date prior to the related Determination Date.

(b) Upon surrender for registration of transfer of any Certificate at any office or agency of the Trustee maintained for such purpose pursuant to Section 8.12 and, in the case of any Class SB Certificate or Class R Certificate, upon satisfaction of the conditions set forth below, the Trustee shall execute and the Certificate Registrar shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of a like Class and aggregate Percentage Interest.

(c) At the option of the Certificateholders, Certificates may be exchanged for other Certificates of authorized denominations of a like Class and aggregate Percentage Interest, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange the Trustee shall execute and the Certificate Registrar shall authenticate and deliver the Certificates of such Class which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for transfer or exchange shall (if so required by the Trustee or the Certificate Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Certificate Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing.

(d) No transfer, sale, pledge or other disposition of a Class B Certificate, Class SB Certificate or Class R Certificate shall be made unless such transfer, sale, pledge or other disposition is exempt from the registration requirements of the Securities Act of 1933, as amended (the “1933 Act”), and any applicable state securities laws or is made in accordance with said Act and laws. Except as otherwise provided in this Section 5.02(d), in the event that a transfer of a Class B Certificate, Class SB Certificate or Class R Certificate is to be made, (i) unless the Depositor directs the Trustee otherwise, the Trustee shall require a written Opinion of Counsel acceptable to and in form and substance satisfactory to the Trustee and the Depositor that such transfer may be made pursuant to an exemption, describing the applicable exemption and the basis therefor, from said Act and laws or is being made pursuant to said Act and laws, which Opinion of Counsel shall not be an expense of the Trustee, the Trust Fund, the Depositor or the Master Servicer, and (ii) the Trustee shall require the transferee to execute a representation letter, substantially in the form of Exhibit I hereto, and the Trustee shall require the transferor to execute a representation letter, substantially in the form of Exhibit J hereto, each acceptable to and in form and substance satisfactory to the Depositor and the Trustee certifying to the Depositor and the Trustee the facts surrounding such transfer, which representation letters shall not be an expense of the Trustee, the Trust Fund, the Depositor or the Master Servicer. In lieu of the requirements set forth in the preceding sentence, transfers of Class B Certificates, Class SB Certificates or Class R Certificates may be made in accordance with this Section 5.02(d) if the prospective transferee of such a Certificate provides the Trustee and the Master Servicer with an investment letter substantially in the form of Exhibit N attached hereto, which investment letter shall not be an expense of the Trustee, the Depositor, or the Master Servicer, and which investment letter states that, among other things, such transferee (i) is a “qualified institutional buyer” as defined under Rule 144A, acting for its own account or the accounts of other “qualified institutional buyers” as defined under Rule 144A, and (ii) is aware that the proposed transferor intends to rely on the exemption from registration requirements under the 1933 Act provided by Rule 144A. The Holder of a Class B Certificate, Class SB Certificate or Class R Certificate desiring to effect any transfer, sale, pledge or other disposition shall, and does hereby agree to, indemnify the Trustee, the Depositor, the Master Servicer and the Certificate Registrar against any liability that may result if the transfer, sale, pledge or other disposition is not so exempt or is not made in accordance with such federal and state laws and this Agreement. If any transfer of a Class B Certificate held by a transferor and to be held by a transferee in book-entry form is to made without registration under the 1933 Act, the transferor shall be deemed to have made each of the certifications set forth in Exhibit J hereto as of the transfer date and the transferee shall be deemed to have made each of the certifications set forth in Exhibit N hereto as of the transfer date, in each case as if such Class B Certificate were in physical form.

(e) (i) In the case of any Class SB Certificate or Class R Certificate presented for registration in the name of any Person, either (A) the Trustee shall require an Opinion of Counsel acceptable to and in form and substance satisfactory to the Trustee, the Depositor and the Master Servicer to the effect that the purchase or holding of such Class SB Certificate or Class R Certificate is permissible under applicable law, will not constitute or result in any non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code (or comparable provisions of any subsequent enactments), and will not subject the Trustee, the Depositor or the Master Servicer to any obligation or liability (including obligations or liabilities under ERISA or Section 4975 of the Code) in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of the Trustee, the Depositor or the Master Servicer, or (B) the prospective transferee shall be required to provide the Trustee, the Depositor and the Master Servicer with a certification to the effect set forth in Exhibit P (with respect to a Class SB Certificate) or in paragraph fifteen of Exhibit H-1 (with respect to a Class R Certificate), which the Trustee may rely upon without further inquiry or investigation, or such other certifications as the Trustee may deem desirable or necessary in order to establish that such transferee or the Person in whose name such registration is requested is not an employee benefit plan or other plan or arrangement subject to the prohibited transaction provisions of ERISA or Section 4975 of the Code, or any Person (including an insurance company investing its general accounts, an investment manager, a named fiduciary or a trustee of any such plan) who is using “plan assets” of any such plan to effect such acquisition (each of the foregoing, a “Plan Investor”).

(ii) Any Transferee of a Class B Certificate or Class M Certificate will be deemed to have represented by virtue of its purchase or holding of such Certificate (or interest therein) that either (a) such Transferee is not a Plan Investor, (b) it has acquired and is holding such Certificate in reliance on U.S. Department of Labor Prohibited Transaction Exemption (“PTE”) 94-29, as most recently amended, 67 Fed. Reg. 54487 (Aug. 22, 2002) (the “RFC Exemption”), and that it understands that there are certain conditions to the availability of the RFC Exemption, including that such Certificate must be rated, at the time of purchase, not lower than “BBB-” (or its equivalent) by Fitch, Standard & Poor’s or Moody’s (which, with respect to any Class B Certificate is not applicable as of the Closing Date) or (c) (x) such Transferee is an insurance company, (y) the source of funds used to purchase or hold such Certificate (or interest therein) is an “insurance company general account” (as defined in Prohibited Transaction Class Exemption (“PTCE”) 95-60), and (z) the conditions set forth in Sections I and III of PTCE 95-60 have been satisfied (each entity that satisfies this clause (c), a “Complying Insurance Company”).

(iii) If any Class B Certificate or Class M Certificate (or any interest therein) is acquired or held by any Person that does not satisfy the conditions described in paragraph (ii) above, then the last preceding Transferee that either (x) is not a Plan Investor, (y) acquired such Certificate in compliance with the RFC Exemption or (z) is a Complying Insurance Company shall be restored, to the extent permitted by law, to all rights and obligations as Certificate Owner thereof retroactive to the date of such Transfer of such Class B Certificate or Class M Certificate. The Trustee shall be under no liability to any Person for making any payments due on such Certificate to such preceding Transferee.

(iv) Any purported Certificate Owner whose acquisition or holding of any Class B Certificate or Class M Certificate (or interest therein) was effected in violation of the restrictions in this Section 5.02(e) shall indemnify and hold harmless the Depositor, the Trustee, the Master Service, any Subservicer, any underwriter and the Trust Fund from and against any and all liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition or holding.

(f) (i) Each Person who has or who acquires any Ownership Interest in a Class R Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions and to have irrevocably authorized the Trustee or its designee under clause (iii)(A) below to deliver payments to a Person other than such Person and to negotiate the terms of any mandatory sale under clause (iii)(B) below and to execute all instruments of transfer and to do all other things necessary in connection with any such sale. The rights of each Person acquiring any Ownership Interest in a Class R Certificate are expressly subject to the following provisions:

(A) Each Person holding or acquiring any Ownership Interest in a Class R Certificate shall be a Permitted Transferee and shall promptly notify the Trustee of any change or impending change in its status as a Permitted Transferee.

(B) In connection with any proposed Transfer of any Ownership Interest in a Class R Certificate, the Trustee shall require delivery to it, and shall not register the Transfer of any Class R Certificate until its receipt of:

(I) an affidavit and agreement (a “Transfer Affidavit and Agreement,” in the form attached hereto as Exhibit H-1) from the proposed Transferee, in form and substance satisfactory to the Master Servicer, representing and warranting, among other things, that it is a Permitted Transferee, that it is not acquiring its Ownership Interest in the Class R Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person who is not a Permitted Transferee, that for so long as it retains its Ownership Interest in a Class R Certificate, it will endeavor to remain a Permitted Transferee, and that it has reviewed the provisions of this Section 5.02(f) and agrees to be bound by them, and

(II) a certificate, in the form attached hereto as Exhibit H-2, from the Holder wishing to transfer the Class R Certificate, in form and substance satisfactory to the Master Servicer, representing and warranting, among other things, that no purpose of the proposed Transfer is to impede the assessment or collection of tax.

(C) Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed Transferee under clause (B) above, if a Responsible Officer of the Trustee who is assigned to this Agreement has actual knowledge that the proposed Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest in a Class R Certificate to such proposed Transferee shall be effected.

(D) Each Person holding or acquiring any Ownership Interest in a Class R Certificate shall agree (x) to require a Transfer Affidavit and Agreement from any other Person to whom such Person attempts to transfer its Ownership Interest in a Class R Certificate and (y) not to transfer its Ownership Interest unless it provides a certificate to the Trustee in the form attached hereto as Exhibit H-2.

(E) Each Person holding or acquiring an Ownership Interest in a Class R Certificate, by purchasing an Ownership Interest in such Certificate, agrees to give the Trustee written notice that it is a “pass-through interest holder” within the meaning of Temporary Treasury Regulations Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership Interest in a Class R Certificate, if it is, or is holding an Ownership Interest in a Class R Certificate on behalf of, a “pass-through interest holder.”

(ii) The Trustee shall register the Transfer of any Class R Certificate only if it shall have received the Transfer Affidavit and Agreement, a certificate of the Holder requesting such transfer in the form attached hereto as Exhibit H-2 and all of such other documents as shall have been reasonably required by the Trustee as a condition to such registration. Transfers of the Class R Certificates to Non-United States Persons and Disqualified Organizations (as defined in Section 860E(e)(5) of the Code) are prohibited.

(A) If any Disqualified Organization shall become a holder of a Class R Certificate, then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such Transfer of such Class R Certificate. If a Non-United States Person shall become a holder of a Class R Certificate, then the last preceding United States Person shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such Transfer of such Class R Certificate. If a transfer of a Class R Certificate is disregarded pursuant to the provisions of Treasury Regulations Section 1.860E-1 or Section 1.860G-3, then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such Transfer of such Class R Certificate. The Trustee shall be under no liability to any Person for any registration of Transfer of a Class R Certificate that is in fact not permitted by this Section 5.02(f) or for making any payments due on such Certificate to the holder thereof or for taking any other action with respect to such holder under the provisions of this Agreement.

(B) If any purported Transferee shall become a Holder of a Class R Certificate in violation of the restrictions in this Section 5.02(f) and to the extent that the retroactive restoration of the rights of the Holder of such Class R Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Master Servicer shall have the right, without notice to the holder or any prior holder of such Class R Certificate, to sell such Class R Certificate to a purchaser selected by the Master Servicer on such terms as the Master Servicer may choose. Such purported Transferee shall promptly endorse and deliver each Class R Certificate in accordance with the instructions of the Master Servicer. Such purchaser may be the Master Servicer itself or any Affiliate of the Master Servicer. The proceeds of such sale, net of the commissions (which may include commissions payable to the Master Servicer or its Affiliates), expenses and taxes due, if any, will be remitted by the Master Servicer to such purported Transferee. The terms and conditions of any sale under this clause (iii)(B) shall be determined in the sole discretion of the Master Servicer, and the Master Servicer shall not be liable to any Person having an Ownership Interest in a Class R Certificate as a result of its exercise of such discretion.

(iii) The Master Servicer, on behalf of the Trustee, shall make available, upon written request from the Trustee, all information necessary to compute any tax imposed

(A) as a result of the Transfer of an Ownership Interest in a Class R Certificate to any Person who is a Disqualified Organization, including the information regarding “excess inclusions” of such Class R Certificates required to be provided to the Internal Revenue Service and certain Persons as described in Treasury Regulations Sections 1.860D-1(b)(5) and 1.860E-2(a)(5), and

(B) as a result of any regulated investment company, real estate investment trust, common trust fund, partnership, trust, estate or organization described in Section 1381 of the Code that holds an Ownership Interest in a Class R Certificate having as among its record holders at any time any Person who is a Disqualified Organization. Reasonable compensation for providing such information may be required by the Master Servicer from such Person.

(iv) The provisions of this Section 5.02(f) set forth prior to this clause (v) may be modified, added to or eliminated, provided that there shall have been delivered to the Trustee the following:

(A) Written notification from each Rating Agency to the effect that the modification, addition to or elimination of such provisions will not cause such Rating Agency to downgrade its then-current ratings, if any, of the Class A Certificates or Class M Certificates 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

(B) a certificate of the Master Servicer stating that the Master Servicer has received an Opinion of Counsel, in form and substance satisfactory to the Master Servicer, to the effect that such modification, addition to or absence of such provisions will not cause any REMIC created hereunder to cease to qualify as a REMIC and will not cause (x) any REMIC created hereunder to be subject to an entity-level tax caused by the Transfer of any Class R Certificate to a Person that is a Disqualified Organization or (y) a Certificateholder or another Person to be subject to a REMIC-related tax caused by the Transfer of a Class R Certificate to a Person that is not a Permitted Transferee.

(g) No service charge shall be made for any transfer or exchange of Certificates of any Class, but the Trustee 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.

(h) All Certificates surrendered for transfer and exchange shall be destroyed by the Certificate Registrar.

Section 5.03. Mutilated, Destroyed, Lost or Stolen Certificates.

If (i) any mutilated Certificate is surrendered to the Certificate Registrar, or the Trustee and the Certificate Registrar receive evidence to their satisfaction of the destruction, loss or theft of any Certificate, and (ii) there is delivered to the Trustee and the Certificate Registrar such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee or the Certificate Registrar that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute and the Certificate Registrar shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor, Class and Percentage Interest but bearing a number not contemporaneously outstanding. Upon the issuance of any new Certificate under this Section, the Trustee 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 Trustee and the Certificate Registrar) connected therewith. Any duplicate Certificate issued pursuant to this Section 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 Master Servicer, the Trustee, the Certificate Registrar and any agent of the Depositor, the Master Servicer, the Trustee or the Certificate Registrar 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 4.02 and for all other purposes whatsoever, except as and to the extent provided in the definition of “Certificateholder,” and neither the Depositor, the Master Servicer, the Trustee, the Certificate Registrar nor any agent of the Depositor, the Master Servicer, the Trustee or the Certificate Registrar shall be affected by notice to the contrary except as provided in Section 5.02(f).

Section 5.05. Appointment of Paying Agent.

The Trustee may appoint a Paying Agent for the purpose of making distributions to Certificateholders pursuant to Section 4.02. In the event of any such appointment, on or prior to each Distribution Date the Master Servicer on behalf of the Trustee shall deposit or cause to be deposited with the Paying Agent a sum sufficient to make the payments to Certificateholders in the amounts and in the manner provided for in Section 4.02, such sum to be held in trust for the benefit of Certificateholders. The Trustee shall cause each Paying Agent 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 shall be paid to such Certificateholders. Any sums so held by such Paying Agent shall be held only in Eligible Accounts to the extent such sums are not distributed to the Certificateholders on the date of receipt by such Paying Agent.

ARTICLE VI

THE DEPOSITOR AND THE MASTER SERVICER

Section 6.01. Respective Liabilities of the Depositor and the Master Servicer.

The Depositor and the Master Servicer shall each be liable in accordance herewith only to the extent of the obligations specifically and respectively imposed upon and undertaken by the Depositor and the Master Servicer herein. By way of illustration and not limitation, the Depositor is not liable for the servicing and administration of the Mortgage Loans, nor is it obligated by Section 7.01 or Section 10.01 to assume any obligations of the Master Servicer or to appoint a designee to assume such obligations, nor is it liable for any other obligation hereunder that it may, but is not obligated to, assume unless it elects to assume such obligation in accordance herewith.

Section 6.02. Merger or Consolidation of the Depositor or the Master Servicer; Assignment of Rights and Delegation of Duties by Master Servicer.

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

(b) Any Person into which the Depositor or the Master Servicer may be merged or consolidated, or any corporation resulting from any merger or consolidation to which the Depositor or the Master Servicer shall be a party, or any Person succeeding to the business of the Depositor or the Master Servicer, shall be the successor of the Depositor or the Master Servicer, as the case may be, 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; provided, however, that the successor or surviving Person to the Master Servicer shall be qualified to service mortgage loans on behalf of Fannie Mae or Freddie Mac; and provided further that each Rating Agency’s ratings, if any, of any Class A Certificates, Class M Certificates or Class B Certificates in effect immediately prior to such merger or consolidation will not be qualified, reduced or withdrawn as a result thereof (as evidenced by a letter to such effect from each Rating Agency).

(c) Notwithstanding anything else in this Section 6.02 and Section 6.04 to the contrary, the Master Servicer may assign its rights and delegate its duties and obligations under this Agreement; provided that the Person accepting such assignment or delegation shall be a Person which is qualified to service mortgage loans on behalf of Fannie Mae or Freddie Mac, is reasonably satisfactory to the Trustee and the Depositor, is willing to service the Mortgage Loans and executes and delivers to the Depositor and the Trustee an agreement, in form and substance reasonably satisfactory to the Depositor and the Trustee, which contains an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed or observed by the Master Servicer under this Agreement; provided further that each Rating Agency’s rating of the Classes of Certificates that have been rated in effect immediately prior to such assignment and delegation will not be qualified, reduced or withdrawn as a result of such assignment and delegation (as evidenced by a letter to such effect from each Rating Agency). In the case of any such assignment and delegation, the Master Servicer shall be released from its obligations under this Agreement, except that the Master Servicer shall remain liable for all liabilities and obligations incurred by it as Master Servicer hereunder prior to the satisfaction of the conditions to such assignment and delegation set forth in the next preceding sentence.

Section 6.03. Limitation on Liability of the Depositor, the Master Servicer and Others.

None of the Depositor, the Master Servicer or any of the directors, officers, employees or agents of the Depositor or the Master Servicer shall be under any liability to the Trust Fund or the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Master Servicer or any such Person against any breach of warranties, representations or covenants made herein or any liability which would otherwise be imposed by reason of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder. The Depositor, the Master Servicer and any director, officer, employee or agent of the Depositor or the Master Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Depositor, the Master Servicer and any director, officer, employee or agent of the Depositor or the Master Servicer shall be indemnified by the Trust Fund and held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Agreement or the Certificates, other than any loss, liability or expense related to any specific Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement) and any loss, liability or expense incurred by reason of willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder. Neither the Depositor nor the Master Servicer shall be under any obligation to appear in, prosecute or defend any legal or administrative action, proceeding, hearing or examination that is not incidental to its respective duties under this Agreement and which in its opinion may involve it in any expense or liability; provided, however, that the Depositor or the Master Servicer may in its discretion undertake any such action, proceeding, hearing or examination that it may deem necessary or desirable in respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action, proceeding, hearing or examination and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund, and the Depositor and the Master Servicer shall be entitled to be reimbursed therefor out of amounts attributable to the Mortgage Loans on deposit in the Custodial Account as provided by Section 3.10 and, on the Distribution Date(s) following such reimbursement, the aggregate of such expenses and costs shall be allocated in reduction of the Accrued Certificate Interest on each Class entitled thereto in the same manner as if such expenses and costs constituted a Prepayment Interest Shortfall.

Section 6.04. Depositor and Master Servicer Not to Resign.

Subject to the provisions of Section 6.02, neither the Depositor nor the Master Servicer shall resign from its respective obligations and duties hereby imposed on it except upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination permitting the resignation of the Depositor or the Master Servicer shall be evidenced by an Opinion of Counsel (at the expense of the resigning party) to such effect delivered to the Trustee. No such resignation by the Master Servicer shall become effective until the Trustee or a successor servicer shall have assumed the Master Servicer’s responsibilities and obligations in accordance with Section 7.02.

ARTICLE VII

DEFAULT

Section 7.01. Events of Default.

Event of Default, wherever used herein, means any one of the following events (whatever 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):

(i)

the Master Servicer shall fail to distribute or cause to be distributed to Holders of Certificates of any Class any distribution required to be made under the terms of the Certificates of such Class and this Agreement and, in either case, such failure shall continue unremedied for a period of 5 days after the date upon which written notice of such failure, requiring such failure to be remedied, shall have been given to the Master Servicer by the Trustee or the Depositor or to the Master Servicer, the Depositor and the Trustee by the Holders of Certificates of such Class evidencing Percentage Interests aggregating not less than 25%; or

(ii)

the Master Servicer shall fail to observe or perform in any material respect any other of the covenants or agreements on the part of the Master Servicer contained in the Certificates of any Class or in this Agreement and such failure shall continue unremedied for a period of 30 days (except that such number of days shall be 15 in the case of a failure to pay the premium for any Required Insurance Policy) after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Trustee or the Depositor, or to the Master Servicer, the Depositor and the Trustee by the Holders of Certificates of any Class evidencing, as to such Class, Percentage Interests aggregating not less than 25%; or

(iii)

a decree or order of a court or agency or supervisory authority having jurisdiction in the premises in an involuntary case under any present or future federal or state bankruptcy, insolvency or similar law or appointing a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; or

(iv)

the Master Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities, or similar proceedings of, or relating to, the Master Servicer or of, or relating to, all or substantially all of the property of the Master Servicer; or

(v)

the Master Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of, or commence a voluntary case under, any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

(vi)

the Master Servicer shall notify the Trustee pursuant to Section 4.04(b) that it is unable to deposit in the Certificate Account an amount equal to the Advance.

If an Event of Default described in clauses (i)-(v) of this Section shall occur, then, and in each and every such case, so long as such Event of Default shall not have been remedied, either the Depositor or the Trustee shall at the direction of Holders of Certificates entitled to at least 51% of the Voting Rights by notice in writing to the Master Servicer (and to the Depositor), terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder; provided, however, that a successor to the Master Servicer is appointed pursuant to Section 7.02 and such successor Master Servicer shall have accepted the duties of Master Servicer effective upon the resignation of the Master Servicer. If an Event of Default described in clause (vi) hereof shall occur, the Trustee shall, by notice to the Master Servicer and the Depositor, immediately terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder as provided in Section 4.04(b). On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer under this Agreement, whether with respect to the Certificates (other than as a Holder thereof) or the Mortgage Loans or otherwise, shall subject to Section 7.02 pass to and be vested in the Trustee or the Trustee’s designee appointed pursuant to Section 7.02; 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 responsibilities and rights hereunder, including, without limitation, the transfer to the Trustee or its designee for administration by it of all cash amounts which shall at the time be credited to the Custodial Account or the Certificate Account or thereafter be received with respect to the Mortgage Loans. No such termination shall release the Master Servicer for any liability that it would otherwise have hereunder for any act or omission prior to the effective time of such termination. Notwithstanding any termination of the activities of Residential Funding in its capacity as Master Servicer hereunder, Residential Funding shall be entitled to receive, out of any late collection of a Monthly Payment on a Mortgage Loan which was due prior to the notice terminating Residential Funding’s rights and obligations as Master Servicer hereunder and received after such notice, that portion to which Residential Funding would have been entitled pursuant to Sections 3.10(a)(ii), (vi) and (vii) as well as its Servicing Fee in respect thereof, and any other amounts payable to Residential Funding hereunder the entitlement to which arose prior to the termination of its activities hereunder. Upon the termination of Residential Funding as Master Servicer hereunder the Depositor shall deliver to the Trustee, as successor Master Servicer, a copy of the Program Guide.

Section 7.02. Trustee or Depositor to Act; Appointment of Successor.

(a) On and after the time the Master Servicer receives a notice of termination pursuant to Section 7.01 or resigns in accordance with Section 6.04, the Trustee or, upon notice to the Depositor and with the Depositor’s consent (which shall not be unreasonably withheld) a designee (which meets the standards set forth below) of the Trustee, shall be the successor in all respects to the Master Servicer in its capacity as servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer (except for the responsibilities, duties and liabilities contained in Sections 2.02 and 2.03(a), excluding the duty to notify related Subservicers as set forth in such Sections, and its obligations to deposit amounts in respect of losses incurred prior to such notice or termination on the investment of funds in the Custodial Account or the Certificate Account pursuant to Sections 3.07(c) and 4.01(c) by the terms and provisions hereof); provided, however, that any failure to perform such duties or responsibilities caused by the preceding Master Servicer’s failure to provide information required by Section 4.04 shall not be considered a default by the Trustee hereunder as successor Master Servicer. As compensation therefor, the Trustee as successor Master Servicer shall be entitled to all funds relating to the Mortgage Loans which the Master Servicer would have been entitled to charge to the Custodial Account or the Certificate Account if the Master Servicer had continued to act hereunder and, in addition, shall be entitled to the income from any Permitted Investments made with amounts attributable to the Mortgage Loans held in the Custodial Account or the Certificate Account. If the Trustee has become the successor to the Master Servicer in accordance with Section 6.04 or Section 7.01, then notwithstanding the above, the Trustee may, if it shall be unwilling to so act, or shall, if it is unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established housing and home finance institution, which is also a Fannie Mae or Freddie Mac-approved mortgage servicing institution, 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. Pending appointment of a successor to the Master Servicer hereunder, the Trustee shall become successor to the Master Servicer and 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 Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted the initial Master Servicer hereunder. The Depositor, the Trustee, the Custodian and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. The Servicing Fee for any successor Master Servicer appointed pursuant to this Section 7.02 will be lowered with respect to those Mortgage Loans, if any, where the Subservicing Fee accrues at a rate of less than 0.50% per annum in the event that the successor Master Servicer is not servicing such Mortgage Loans directly and it is necessary to raise the related Subservicing Fee to a rate of 0.50% per annum in order to hire a Subservicer with respect to such Mortgage Loans. The Master Servicer shall pay the reasonable expenses of the Trustee in connection with any servicing transfer hereunder.

(b) In connection with the termination or resignation of the Master Servicer hereunder, either (i) the successor Master Servicer, including the Trustee if the Trustee is acting as successor Master Servicer, shall represent and warrant that it is a member of MERS in good standing and shall agree to comply in all material respects with the rules and procedures of MERS in connection with the servicing of the Mortgage Loans that are registered with MERS, in which case the predecessor Master Servicer shall cooperate with the successor Master Servicer in causing MERS to revise its records to reflect the transfer of servicing to the successor Master Servicer as necessary under MERS’ rules and regulations, or (ii) the predecessor Master Servicer shall cooperate with the successor Master Servicer in causing MERS to execute and deliver an assignment of Mortgage in recordable form to transfer the Mortgage from MERS to the Trustee and to execute and deliver such other notices, documents and other instruments as may be necessary or desirable to effect a transfer of such Mortgage Loan or servicing of such Mortgage Loan on the MERS® System to the successor Master Servicer. The predecessor Master Servicer shall file or cause to be filed any such assignment in the appropriate recording office. The predecessor Master Servicer shall bear any and all fees of MERS, costs of preparing any assignments of Mortgage, and fees and costs of filing any assignments of Mortgage that may be required under this subsection (b). The successor Master Servicer shall cause such assignment to be delivered to the Trustee or the Custodian promptly upon receipt of the original with evidence of recording thereon or a copy certified by the public recording office in which such assignment was recorded.

Section 7.03. Notification to Certificateholders.

(a) Upon any such 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.

(b) Within 60 days after the occurrence of any Event of Default, the Trustee shall transmit by mail to all Holders of Certificates notice of each such Event of Default hereunder known to the Trustee, unless such Event of Default shall have been cured or waived as provided in Section 7.04 hereof.

Section 7.04. Waiver of Events of Default.

The Holders representing at least 66% of the Voting Rights of Certificates affected by a default or Event of Default hereunder may waive any default or Event of Default; provided, however, that (a) a default or Event of Default under clause (i) of Section 7.01 may be waived only by all of the Holders of Certificates affected by such default or Event of Default and (b) no waiver pursuant to this Section 7.04 shall affect the Holders of Certificates in the manner set forth in Section 11.01(b)(i), (ii) or (iii). Upon any such waiver of a default or Event of Default by the Holders representing the requisite percentage of Voting Rights of Certificates affected by such default or Event of Default, such default or Event of Default shall cease to exist and shall be deemed to have been remedied for every purpose hereunder. No such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon except to the extent expressly so waived.

ARTICLE VIII

CONCERNING THE TRUSTEE

Section 8.01. Duties of Trustee.

(a)

The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise as a prudent investor would exercise or use under the circumstances in the conduct of such investor’s own affairs.

(b)

The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they conform to the requirements of this Agreement. The Trustee shall notify the Certificateholders of any such documents which do not materially conform to the requirements of this Agreement in the event that the Trustee, after so requesting, does not receive satisfactorily corrected documents. The Trustee shall forward or cause to be forwarded in a timely fashion the notices, reports and statements required to be forwarded by the Trustee pursuant to Sections 4.03, 7.03, and 10.01. The Trustee shall furnish in a timely fashion to the Master Servicer such information as the Master Servicer may reasonably request from time to time for the Master Servicer to fulfill its duties as set forth in this Agreement. The Trustee covenants and agrees that it shall perform its obligations hereunder in a manner so as to maintain the status of each REMIC created hereunder as a REMIC under the REMIC Provisions and (subject to Section 10.01(f)) to prevent the imposition of any federal, state or local income, prohibited transaction, contribution or other tax on the Trust Fund to the extent that maintaining such status and avoiding such taxes are reasonably within the control of the Trustee and are reasonably within the scope of its duties under this Agreement.

(c)

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

(i)

Prior to the occurrence of an Event of Default, and after the curing or waiver of all such Events of Default which may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and, in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee by the Depositor or the Master Servicer and which on their face, do not contradict the requirements of this Agreement;

(ii)

The Trustee shall not be personally liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(iii)

The Trustee shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Certificateholders holding Certificates which evidence, Percentage Interests aggregating not less than 25% of the affected Classes as to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement;

(iv)

The Trustee shall not be charged with knowledge of any default (other than a default in payment to the Trustee) specified in clauses (i) and (ii) of Section 7.01 or an Event of Default under clauses (iii), (iv) and (v) of Section 7.01 unless a Responsible Officer of the Trustee assigned to and working in the Corporate Trust Office obtains actual knowledge of such failure or event or the Trustee receives written notice of such failure or event at its Corporate Trust Office from the Master Servicer, the Depositor or any Certificateholder; and

(v)

Except to the extent provided in Section 7.02, no provision in this Agreement shall require the Trustee to expend or risk its own funds (including, without limitation, the making of any Advance) or otherwise incur any personal financial liability in the performance of any of its duties as Trustee hereunder, or in the exercise of any of its rights or powers, if the Trustee shall have reasonable grounds for believing that repayment of funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(d)

The Trustee shall timely pay, from its own funds, the amount of any and all federal, state and local taxes imposed on the Trust Fund or its assets or transactions including, without limitation, (A) “prohibited transaction” penalty taxes as defined in Section 860F of the Code, if, when and as the same shall be due and payable, (B) any tax on contributions to a REMIC after the Closing Date imposed by Section 860G(d) of the Code and (C) any tax on “net income from foreclosure property” as defined in Section 860G(c) of the Code, but only if such taxes arise out of a breach by the Trustee of its obligations hereunder, which breach constitutes negligence or willful misconduct of the Trustee.

Section 8.02. Certain Matters Affecting the Trustee.

(a)

Except as otherwise provided in Section 8.01:

(i)

The Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, Officers Certificate, 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;

(ii)

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

(iii)

The Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders pursuant to the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default (which has not been cured), 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 investor would exercise or use under the circumstances in the conduct of such investor’s own affairs;

(iv)

The Trustee shall not be personally liable 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)

Prior to the occurrence of an Event of Default hereunder and after the curing of all Events of Default which may have occurred, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing so to do by the Holders of Certificates of any Class evidencing, as to such Class, Percentage Interests, aggregating not less than 50%; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Agreement, the Trustee may require reasonable indemnity against such expense or liability as a condition to so proceeding. The reasonable expense of every such examination shall be paid by the Master Servicer, if an Event of Default shall have occurred and is continuing, and otherwise by the Certificateholder requesting the investigation;

(vi)

The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys provided that the Trustee shall remain liable for any acts of such agents or attorneys; and

(vii)

To the extent authorized under the Code and the regulations promulgated thereunder, each Holder of a Class R Certificate hereby irrevocably appoints and authorizes the Trustee to be its attorney-in-fact for purposes of signing any Tax Returns required to be filed on behalf of the Trust Fund. The Trustee shall sign on behalf of the Trust Fund and deliver to the Master Servicer in a timely manner any Tax Returns prepared by or on behalf of the Master Servicer that the Trustee is required to sign as determined by the Master Servicer pursuant to applicable federal, state or local tax laws, provided that the Master Servicer shall indemnify the Trustee for signing any such Tax Returns that contain errors or omissions.

(b)

Following the issuance of the Certificates (and except as provided for in Section 2.04), the Trustee shall not accept any contribution of assets to the Trust Fund unless (subject to Section 10.01(f)) it shall have obtained or been furnished with an Opinion of Counsel to the effect that such contribution will not (i) cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding or (ii) cause the Trust Fund to be subject to any federal tax as a result of such contribution (including the imposition of any federal tax on “prohibited transactions” imposed under Section 860F(a) of the Code).

Section 8.03. Trustee Not Liable for Certificates or Mortgage Loans.

The recitals contained herein and in the Certificates (other than the execution of the Certificates and relating to the acceptance and receipt of the Mortgage Loans) shall be taken as the statements of the Depositor or the Master Servicer as the case may be, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Agreement or of the Certificates (except that the Certificates shall be duly and validly executed and authenticated by it as Certificate Registrar) or of any Mortgage Loan or related document, or of MERS or the MERS® System. Except as otherwise provided herein, the Trustee shall not be accountable for the use or application by the Depositor or the Master Servicer 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 or the Master Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Custodial Account or the Certificate Account by the Depositor or the Master Servicer.

Section 8.05. Master Servicer to Pay Trustee's Fees and Expenses; Indemnification.

(a) The Master Servicer covenants and agrees to pay to the Trustee and any co-trustee from time to time, and the Trustee and any co-trustee shall be entitled to, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) for all services rendered by each of them in the execution of the trusts hereby created and in the exercise and performance of any of the powers and duties hereunder of the Trustee and any co-trustee, and the Master Servicer shall pay or reimburse the Trustee and any co-trustee upon request for all reasonable expenses, disbursements and advances incurred or made by the Trustee or any co-trustee 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, and the expenses incurred by the Trustee or any co-trustee in connection with the appointment of an office or agency pursuant to Section 8.12) except any such expense, disbursement or advance as may arise from its negligence or bad faith.

(b) The Master Servicer agrees to indemnify the Trustee for, and to hold the Trustee harmless against, any loss, liability or expense incurred without negligence or willful misconduct on its part, arising out of, or in connection with, the acceptance and administration of the Trust Fund, including its obligation to execute the DTC Letter in its individual capacity, and including the costs and expenses (including reasonable legal fees and expenses) of defending itself against any claim in connection with the exercise or performance of any of its powers or duties under this Agreement, and the Master Servicer further agrees to indemnify the Trustee for, and to hold the Trustee harmless against, any loss, liability or expense arising out of, or in connection with, the provisions set forth in the third paragraph of Section 2.01(b) hereof, including without limitation, all costs, liabilities and expenses (including reasonable legal fees and expenses) of investigating and defending itself against any claim, action or proceeding, pending or threatened, relating to the provisions of such paragraph, provided that:

(i) with respect to any such claim, the Trustee shall have given the Master Servicer written notice thereof promptly after the Trustee shall have actual knowledge thereof;

(ii) while maintaining control over its own defense, the Trustee shall cooperate and consult fully with the Master Servicer in preparing such defense; and

(iii) notwithstanding anything in this Agreement to the contrary, the Master Servicer shall not be liable for settlement of any claim by the Trustee entered into without the prior consent of the Master Servicer which consent shall not be unreasonably withheld. No termination of this Agreement shall affect the obligations created by this Section 8.05(b) of the Master Servicer to indemnify the Trustee under the conditions and to the extent set forth herein. Notwithstanding the foregoing, the indemnification provided by the Master Servicer in this Section 8.05(b) shall not pertain to any loss, liability or expense of the Trustee, including the costs and expenses of defending itself against any claim, incurred in connection with any actions taken by the Trustee at the direction of Certificateholders pursuant to the terms of this Agreement.

Section 8.06. Eligibility Requirements for Trustee.

The Trustee hereunder shall at all times be a national banking association or a New York banking corporation having its principal office in a state and city acceptable to the Depositor and 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 of at least $50,000,000 and subject to supervision or examination by federal or state authority. If such corporation or national banking association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for purposes of this Section the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall resign immediately in the manner and with the effect specified in Section 8.07.

Section 8.07. Resignation and Removal of the Trustee.

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

(b) If at any time the Trustee shall cease to be eligible in accordance with the provisions of Section 8.06 and shall fail to resign after written request therefor by the Depositor, or if at any time the Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Depositor may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee. In addition, in the event that the Depositor determines that the Trustee has failed (i) to distribute or cause to be distributed to Certificateholders any amount required to be distributed hereunder, if such amount is held by the Trustee or its Paying Agent (other than the Master Servicer or the Depositor) for distribution or (ii) to otherwise observe or perform in any material respect any of its covenants, agreements or obligations hereunder, and such failure shall continue unremedied for a period of 5 days (in respect of clause (i) above) or 30 days (in respect of clause (ii) above) after the date on which written notice of such failure, requiring that the same be remedied, shall have been given to the Trustee by the Depositor, then the Depositor may remove the Trustee and appoint a successor trustee by written instrument delivered as provided in the preceding sentence. In connection with the appointment of a successor trustee pursuant to the preceding sentence, the Depositor shall, on or before the date on which any such appointment becomes effective, obtain from each Rating Agency written confirmation that the appointment of any such successor trustee will not result in the reduction of the ratings on any Class of the Certificates below the lesser of the then current or original ratings on such Certificates.

(c) The Holders of Certificates entitled to at least 51% of the Voting Rights may at any time remove the Trustee and appoint a successor trustee by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered to the Depositor, one complete set to the Trustee so removed and one complete set to the successor so appointed.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.08.

Section 8.08. Successor Trustee.

(a) Any successor trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee herein. The predecessor trustee shall deliver to the successor trustee all Mortgage Files and related documents and statements held by it hereunder (other than any Mortgage Files at the time held by a Custodian, which shall become the agent of any successor trustee hereunder), and the Depositor, the Master Servicer and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties and obligations.

(b) No successor trustee shall accept appointment as provided in this Section unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 8.06.

(c) Upon acceptance of appointment by a successor trustee as provided in this Section, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register. If the Depositor fails to mail such notice within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Depositor.

Section 8.09. Merger or Consolidation of Trustee.

Any corporation or national banking association into which the Trustee may be merged or converted or with which it may be consolidated or any corporation or national banking association resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or national banking association succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation or national banking association shall be eligible under the provisions of Section 8.06, 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. The Trustee shall mail notice of any such merger or consolidation to the Certificateholders at their address as shown in the Certificate Register.

Section 8.10. 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 Fund or property securing the same may at the time be located, the Master Servicer 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 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 Fund, and to vest in such Person or Persons, in such capacity, such title to the Trust Fund, or any part thereof, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider necessary or desirable. If the Master Servicer shall not have joined in such appointment within 15 days after the receipt by it of a request so to do, or in case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 hereunder, and no notice to Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08 hereof.

(b) In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the 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 Fund 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.

(c) 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 VIII. 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.

(d) Any separate trustee or co-trustee may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of 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.

Section 8.11. Appointment of Custodians.

The Trustee may, with the consent of the Master Servicer and the Depositor, or shall, at the direction of the Master Servicer and the Depositor, appoint one or more Custodians who are not Affiliates of the Depositor or the Master Servicer to hold all or a portion of the Mortgage Files as agent for the Trustee, by entering into a Custodial Agreement. The Trustee is hereby directed to enter into a Custodial Agreement with Wells Fargo Bank, N.A. Subject to Article VIII, the Trustee agrees to comply with the terms of each Custodial Agreement and to enforce the terms and provisions thereof against the Custodian for the benefit of the Certificateholders. Each Custodian shall be a depository institution subject to supervision by federal or state authority, shall have a combined capital and surplus of at least $15,000,000 and shall be qualified to do business in the jurisdiction in which it holds any Mortgage File.

ARTICLE IX

TERMINATION

Section 9.01. Termination Upon Purchase or Liquidation of All Mortgage Loans.

(a)

Subject to Section 9.02, the respective obligations and responsibilities of the Depositor, the Master Servicer and the Trustee created hereby in respect of the Certificates (other than the obligation of the Trustee to make certain payments after the Final Distribution Date to Certificateholders and the obligation of the Depositor to send certain notices as hereinafter set forth) shall terminate upon the last action required to be taken by the Trustee on the Final Distribution Date pursuant to this Article IX following the earlier of:

(i)

the later of the final payment or other liquidation (or any Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or the disposition of all property acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan, or

(ii)

at the option of the Master Servicer or the Holder of the Class SB Certificates as provided in Section 9.01(f), the purchase of all Mortgage Loans and all property acquired in respect of any Mortgage Loan remaining in the Trust Fund, at a price equal to 100% of the unpaid principal balance of each Mortgage Loan (or, if less than such unpaid principal balance, the fair market value of the related underlying property of such Mortgage Loan with respect to Mortgage Loans as to which title has been acquired if such fair market value is less than such unpaid principal balance) (and if such purchase is made by the Master Servicer only, net of any unreimbursed Advances attributable to principal) on the day of repurchase, plus accrued interest thereon at the Net Mortgage Rate (or Modified Net Mortgage Rate in the case of any Modified Mortgage Loan), to, but not including, the first day of the month in which such repurchase price is distributed;

provided, however, that in no event shall the trust created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United States to the Court of St. James, living on the date hereof; and provided further, that the purchase price set forth above shall be increased as is necessary, as determined by the Master Servicer, to avoid disqualification of any REMIC created hereunder as a REMIC.

The purchase price paid by the Master Servicer or the Holder of the Class SB Certificates, as applicable, pursuant to Section 9.01(a)(ii) shall also include any amounts owed by Residential Funding pursuant to the last paragraph of Section 4 of the Assignment Agreement in respect of any liability, penalty or expense that resulted from a breach of the representation and warranty set forth in clause (xlvii) of Section 4 of the Assignment Agreement that remain unpaid on the date of such purchase.

The right of the Master Servicer or the Holder of the Class SB Certificates, as applicable, to purchase all of the Mortgage Loans pursuant to clause (ii) above is conditioned upon the date of such purchase occurring on or after the Optional Termination Date. If such right is exercised by the Master Servicer, the Master Servicer shall be deemed to have been reimbursed for the full amount of any unreimbursed Advances theretofore made by it with respect to the Mortgage Loans being purchased. In addition, the Master Servicer shall provide to the Trustee the certification required by Section 3.15, and the Trustee and any Custodian shall, promptly following payment of the purchase price, release to the Master Servicer or the Holder of the Class SB Certificates, as applicable, the Mortgage Files pertaining to the Mortgage Loans being purchased.

In addition to the foregoing, on any Distribution Date on or after the Optional Termination Date, the Master Servicer or the Holder of the Class SB Certificates as provided in Section 9.01(f), shall have the right, at its option, to purchase the Class A Certificates, Class M Certificates, Class B Certificates and Class SB Certificates in whole, but not in part, at a price equal to the sum of the outstanding Certificate Principal Balance of such Certificates plus the sum of one month’s Accrued Certificate Interest thereon, any previously unpaid Accrued Certificate Interest, and any unpaid Prepayment Interest Shortfalls previously allocated thereto and, in the case of Prepayment Interest Shortfalls, accrued interest thereon at the applicable Pass-Through Rate, plus, with respect to any optional termination by the Holder of the Class SB Certificates, an amount equal to all accrued and unpaid Servicing Fees and reimbursement for all unreimbursed Advances and Servicing Advances, in each case through the date of such optional termination. If the Master Servicer or the Holder of the Class SB Certificates, as applicable, exercises this right to purchase the outstanding Class A Certificates, Class M Certificates, Class B Certificates and Class SB Certificates, the Master Servicer or the Holder of the Class SB Certificates, as applicable, will promptly terminate the respective obligations and responsibilities created hereby in respect of these Certificates pursuant to this Article IX.

(b) The Master Servicer or the Holder of the Class SB Certificates, as applicable, shall give the Trustee (and the Master Servicer if the Holder of the Class SB Certificates is exercising its option) not less than 60 days’ prior notice of the Distribution Date on which (1) the Master Servicer or the Holder of the Class SB Certificates, as applicable, anticipates that the final distribution will be made to Certificateholders as a result of the exercise by the Master Servicer or the Holder of the Class SB Certificates, as applicable, of its right to purchase the Mortgage Loans or on which (2) the Master Servicer or the Holder of the Class SB Certificates, as applicable, anticipates that the Certificates will be purchased as a result of the exercise by the Master Servicer or the Holder of the Class SB Certificates, as applicable, to purchase the outstanding Certificates. Notice of any termination, specifying the anticipated Final Distribution Date (which shall be a date that would otherwise be a Distribution Date) upon which the Certificateholders may surrender their Certificates to the Trustee (if so required by the terms hereof) for payment of the final distribution and cancellation or notice of any purchase of the outstanding Certificates, specifying the Distribution Date upon which the Holders may surrender their Certificates to the Trustee for payment, shall be given promptly by the Master Servicer (if it is exercising the right to purchase the Mortgage Loans or to purchase the outstanding Certificates), or by the Trustee (in any other case) by letter to the Certificateholders (with a copy to the Certificate Registrar) mailed not earlier than the 15th day and not later than the 25th day of the month next preceding the month of such final distribution specifying:

(i) the anticipated Final Distribution Date upon which final payment of the Certificates is anticipated to be made upon presentation and surrender of Certificates at the office or agency of the Trustee therein designated where required pursuant to this Agreement or, in the case of the purchase by the Master Servicer or the Holder of the Class SB Certificates, as applicable, of the outstanding Certificates, the Distribution Date on which such purchase is made,

(ii) the amount of any such final payment or, in the case of the purchase of the outstanding Certificates, the purchase price, in either case, if known, and

(iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, and that payment will be made only upon presentation and surrender of the Certificates at the office or agency of the Trustee therein specified.

If the Master Servicer or the Trustee is obligated to give notice to Certificateholders as required above, it shall give such notice to the Certificate Registrar at the time such notice is given to Certificateholders. In the event of a purchase of the Mortgage Loans by the Master Servicer or the Holder of the Class SB Certificates, as applicable, the Master Servicer or the Holder of the Class SB Certificates, as applicable, shall deposit in the Certificate Account before the Final Distribution Date in immediately available funds an amount equal to the purchase price computed as provided above. As a result of the exercise by the Master Servicer or the Holder of the Class SB Certificates, as applicable, of its right to purchase the outstanding Certificates, the Master Servicer or the Holder of the Class SB Certificates, as applicable, shall deposit in the Certificate Account before the Distribution Date on which such purchase is to occur, in immediately available funds, an amount equal to the purchase price for the Certificates computed as provided above, and provide notice of such deposit to the Trustee. The Trustee shall withdraw from such account the amount specified in subsection (c) below and distribute such amount to the Certificateholders as specified in subsection (c) below. The Master Servicer or the Holder of the Class SB Certificates, as applicable, shall provide to the Trustee written notification of any change to the anticipated Final Distribution Date as soon as practicable. If the Trust Fund is not terminated on the anticipated Final Distribution Date, for any reason, the Trustee shall promptly mail notice thereof to each affected Certificateholder.

(c) Upon presentation and surrender of the Class A Certificates, Class M Certificates, Class B Certificates and Class SB Certificates by the Certificateholders thereof, the Trustee shall distribute to such Certificateholders (i) the amount otherwise distributable on such Distribution Date, if not in connection with the Master Servicer’s or the Holder’s of the Class SB Certificates, as applicable, election to repurchase the Mortgage Loans or the outstanding Class A Certificates, Class M Certificates, Class B Certificates and Class SB Certificates, or (ii) if the Master Servicer or the Holder of the Class SB Certificates, as applicable, elected to so repurchase the Mortgage Loans or the outstanding Class A Certificates, Class M Certificates, Class B Certificates and Class SB Certificates, an amount equal to the price paid pursuant to Section 9.01(a) as follows: first, with respect to any optional termination by the Holder of the Class SB Certificates, payment of any accrued and unpaid Servicing Fees and reimbursement for all unreimbursed Advances and Servicing Advances, in each case through the date of such optional termination, to the Master Servicer, second, with respect to the Class A Certificates, pari passu, the outstanding Certificate Principal Balance thereof, plus Accrued Certificate Interest thereon for the related Interest Accrual Period and any previously unpaid Accrued Certificate Interest, third, with respect to the Class M-1 Certificates, the outstanding Certificate Principal Balance thereof, plus Accrued Certificate Interest thereon for the related Interest Accrual Period and any previously unpaid Accrued Certificate Interest, fourth, with respect to the Class M-2 Certificates, the outstanding Certificate Principal Balance thereof, plus Accrued Certificate Interest thereon for the related Interest Accrual Period and any previously unpaid Accrued Certificate Interest, fifth, with respect to the Class M-3 Certificates, the outstanding Certificate Principal Balance thereof, plus Accrued Certificate Interest thereon for the related Interest Accrual Period and any previously unpaid Accrued Certificate Interest, sixth, with respect to the Class M-4 Certificates, the outstanding Certificate Principal Balance thereof, plus Accrued Certificate Interest thereon for the related Interest Accrual Period and any previously unpaid Accrued Certificate Interest, seventh, with respect to the Class M-5 Certificates, the outstanding Certificate Principal Balance thereof, plus Accrued Certificate Interest thereon for the related Interest Accrual Period and any previously unpaid Accrued Certificate Interest, eighth, with respect to the Class M-6 Certificates, the outstanding Certificate Principal Balance thereof, plus Accrued Certificate Interest thereon for the related Interest Accrual Period and any previously unpaid Accrued Certificate Interest, ninth, with respect to the Class B Certificates, the outstanding Certificate Principal Balance thereof, plus Accrued Certificate Interest thereon for the related Interest Accrual Period and any previously unpaid Accrued Certificate Interest, tenth, to the Class A Certificates, Class M Certificates and Class B Certificates, the amount of any Prepayment Interest Shortfalls allocated thereto for such Distribution Date or remaining unpaid from prior Distribution Dates and accrued interest thereon at the applicable Pass-Through Rate, on a pro rata basis based on Prepayment Interest Shortfalls allocated thereto for such Distribution Date or remaining unpaid from prior Distribution Dates, and eleventh, to the Class SB Certificates.

(d) In the event that any Certificateholders shall not surrender their Certificates for final payment and cancellation on or before the Final Distribution Date, the Master Servicer (if it exercised its right to purchase the Mortgage Loans) or the Trustee (in any other case), 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 any Certificate shall not have been surrendered for cancellation, the Trustee shall take appropriate steps as directed by the Master Servicer to contact the remaining Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining the Certificate Account and of contacting Certificateholders shall be paid out of the assets which remain in the Certificate Account. If within nine months after the second notice any Certificates shall not have been surrendered for cancellation, the Trustee shall pay to the Master Servicer all amounts distributable to the holders thereof and the Master Servicer shall thereafter hold such amounts until distributed to such Holders. No interest shall accrue or be payable to any Certificateholder on any amount held in the Certificate Account or by the Master Servicer as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 9.01 and the Certificateholders shall look only to the Master Servicer for such payment.

(e) If any Certificateholders do not surrender their Certificates on or before the Distribution Date on which a purchase of the outstanding Certificates is to be made, the Master Servicer shall give a second written notice to such Certificateholders to surrender their Certificates for payment of the purchase price therefor. If within six months after the second notice any Certificate shall not have been surrendered for cancellation, the Trustee shall take appropriate steps as directed by the Master Servicer to contact the Holders of such Certificates concerning surrender of their Certificates. The costs and expenses of maintaining the Certificate Account and of contacting Certificateholders shall be paid out of the assets which remain in the Certificate Account. If within nine months after the second notice any Certificates shall not have been surrendered for cancellation in accordance with this Section 9.01, the Trustee shall pay to the Master Servicer all amounts distributable to the Holders thereof and shall have no further obligation or liability therefor and the Master Servicer shall thereafter hold such amounts until distributed to such Holders. No interest shall accrue or be payable to any Certificateholder on any amount held in the Certificate Account or by the Master Servicer as a result of such Certificateholder’s failure to surrender its Certificate(s) for payment in accordance with this Section 9.01. Any Certificate that is not surrendered on the Distribution Date on which a purchase pursuant to this Section 9.01 occurs as provided above will be deemed to have been purchased and the Holder as of such date will have no rights with respect thereto except to receive the purchase price therefor minus any costs and expenses associated with such Certificate Account and notices allocated thereto. Any Certificates so purchased or deemed to have been purchased on such Distribution Date shall remain outstanding hereunder. The Master Servicer shall be for all purposes the Holder thereof as of such date.

(f) With respect to the first possible Optional Termination Date, the Master Servicer shall have the sole option to exercise the purchase options described in Section 9.01(a) and the Holder of the Class SB Certificates shall have no claim thereto. If, however, the Master Servicer elects not to exercise one of its options to purchase pursuant to Section 9.01(a) with respect to the first possible Optional Termination Date, the Holder of the Class SB Certificates shall have the sole option to exercise the purchase options described in Section 9.01(a) on the second possible Optional Termination Date and the Master Servicer shall have no claim thereto. If the Holder of the Class SB Certificates elects not to exercise one of its options to purchase pursuant to Section 9.01(a) with respect to the second possible Optional Termination Date, it shall lose such right and have no claim to exercise any purchase options pursuant to this Section 9.01 thereafter. Beginning with the third possible Optional Termination Date and thereafter, the Master Servicer shall again have the sole option to exercise the purchase options described in Section 9.01(a).

Section 9.02. Additional Termination Requirements.

(a)

Each of REMIC I and REMIC II , as the case may be, shall be terminated in accordance with the following additional requirements, unless the Trustee and the Master Servicer have received an Opinion of Counsel (which Opinion of Counsel shall not be an expense of the Trustee) to the effect that the failure of any REMIC created hereunder to comply with the requirements of this Section 9.02 will not (i) result in the imposition on the Trust Fund of taxes on “prohibited transactions,” as described in Section 860F of the Code, or (ii) cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding:

(i)

The Master Servicer shall establish a 90-day liquidation period for each of REMIC I and REMIC II, and specify the first day of such period in a statement attached to the Trust Fund’s final Tax Return pursuant to Treasury regulations §1.860F-1. The Master Servicer also shall satisfy all of the requirements of a qualified liquidation for each of REMIC I and REMIC II, under Section 860F of the Code and the regulations thereunder;

(ii)

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

(iii)

If the Master Servicer is exercising its right to purchase the assets of the Trust Fund, the Master Servicer shall, during the 90-day liquidation period and at or prior to the Final Distribution Date, purchase all of the assets of the Trust Fund for cash;

(b)

Each Holder of a Certificate and the Trustee hereby irrevocably approves and appoints the Master Servicer as its attorney-in-fact to adopt a plan of complete liquidation for each of REMIC I and REMIC II at the expense of the Trust Fund in accordance with the terms and conditions of this Agreement.

REMIC PROVISIONS

Section 10.01. REMIC Administration.

If the REMIC Administrator is no longer the Master Servicer hereunder, at its option the REMIC Administrator may continue its duties as REMIC Administrator and shall be paid reasonable compensation not to exceed $3,000 per year by any successor Master Servicer hereunder for so acting as the REMIC Administrator.

(e) The REMIC Administrator shall provide (i) to any Transferor of a Class R Certificate such information as is necessary for the application of any tax relating to the transfer of a Class R Certificate to any Person who is not a Permitted Transferee, (ii) to the Trustee and the Trustee shall forward to the Certificateholders such information or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original issue discount, if any, and market discount or premium (using the Prepayment Assumption) and (iii) to the Internal Revenue Service the name, title, address and telephone number of the person who will serve as the representative of each REMIC created hereunder.

(f) The Master Servicer and the REMIC Administrator shall take such actions and shall cause each REMIC created hereunder to take such actions as are reasonably within the Master Servicer’s or the REMIC Administrator’s control and the scope of its duties more specifically set forth herein as shall be necessary or desirable to maintain the status thereof as a REMIC under the REMIC Provisions (and the Trustee shall assist the Master Servicer and the REMIC Administrator, to the extent reasonably requested by the Master Servicer and the REMIC Administrator to do so). In performing their duties as more specifically set forth herein, the Master Servicer and the REMIC Administrator shall not knowingly or intentionally take any action, cause the Trust Fund to take any action or fail to take (or fail to cause to be taken) any action reasonably within their respective 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, could (i) endanger the status of any REMIC created hereunder as a REMIC or (ii) result in the imposition of a tax upon any REMIC created hereunder (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code (except as provided in Section 2.04) and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) (either such event, in the absence of an Opinion of Counsel or the indemnification referred to in this sentence, an “Adverse REMIC Event”) unless the Master Servicer or the REMIC Administrator, as applicable, has received an Opinion of Counsel (at the expense of the party seeking to take such action or, if such party fails to pay such expense, and the Master Servicer or the REMIC Administrator, as applicable, determines that taking such action is in the best interest of the Trust Fund and the Certificateholders, at the expense of the Trust Fund, but in no event at the expense of the Master Servicer, the REMIC Administrator or the Trustee) to the effect that the contemplated action will not, with respect to the Trust Fund created hereunder, endanger such status or, unless the Master Servicer or the REMIC Administrator or both, as applicable, determine in its or their sole discretion to indemnify the Trust Fund against the imposition of such a tax, result in the imposition of such a tax. Wherever in this Agreement a contemplated action may not be taken because the timing of such action might result in the imposition of a tax on the Trust Fund, or may only be taken pursuant to an Opinion of Counsel that such action would not impose a tax on the Trust Fund, such action may nonetheless be taken provided that the indemnity given in the preceding sentence with respect to any taxes that might be imposed on the Trust Fund has been given and that all other preconditions to the taking of such action have been satisfied. The Trustee shall not take or fail to take any action (whether or not authorized hereunder) as to which the Master Servicer or the REMIC Administrator, as applicable, has advised it in writing that it has received an Opinion of Counsel to the effect that an Adverse REMIC Event could occur with respect to such action or inaction, as the case may be. In addition, prior to taking any action with respect to the Trust Fund or its assets, or causing the Trust Fund to take any action, which is not expressly permitted under the terms of this Agreement, the Trustee shall consult with the Master Servicer or the REMIC Administrator, as applicable, or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to the Trust Fund and the Trustee shall not take any such action or cause the Trust Fund to take any such action as to which the Master Servicer or the REMIC Administrator, as applicable, has advised it in writing that an Adverse REMIC Event could occur. The Master Servicer or the REMIC Administrator, as applicable, may consult with counsel to make such written advice, and the cost of same shall be borne by the party seeking to take the action not expressly permitted by this Agreement, but in no event at the expense of the Master Servicer or the REMIC Administrator. At all times as may be required by the Code, the Master Servicer or the REMIC Administrator, as applicable, will to the extent within its control and the scope of its duties more specifically set forth herein, maintain substantially all of the assets of the REMIC as “qualified mortgages” as defined in Section 860G(a)(3) of the Code and “permitted investments” as defined in Section 860G(a)(5) of the Code.

(g) In the event that any tax is imposed on “prohibited transactions” of any REMIC created hereunder as defined in Section 860F(a)(2) of the Code, on “net income from foreclosure property” of any REMIC as defined in Section 860G(c) of the Code, on any contributions to any REMIC after the Startup Date therefor pursuant to Section 860G(d) of the Code, or any other tax imposed by the Code or any applicable provisions of state or local tax laws, such tax shall be charged (i) to the Master Servicer, if such tax arises out of or results from a breach by the Master Servicer in its role as Master Servicer or REMIC Administrator of any of its obligations under this Agreement or the Master Servicer has in its sole discretion determined to indemnify the Trust Fund against such tax, (ii) to the Trustee, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article X, or (iii) otherwise against amounts on deposit in the Custodial Account as provided by Section 3.10 and on the Distribution Date(s) following such reimbursement the aggregate of such taxes shall be allocated in reduction of the Accrued Certificate Interest on each Class entitled thereto in the same manner as if such taxes constituted a Prepayment Interest Shortfall.

(h) The Trustee and the Master Servicer shall, for federal income tax purposes, maintain books and records with respect to each REMIC on a calendar year and on an accrual basis or as otherwise may be required by the REMIC Provisions.

(i) Following the Startup Date, neither the Master Servicer nor the Trustee shall accept any contributions of assets to any REMIC unless (subject to Section 10.01(f)) the Master Servicer and the Trustee shall have received an Opinion of Counsel (at the expense of the party seeking to make such contribution) to the effect that the inclusion of such assets in any REMIC will not cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding or subject any such REMIC to any tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances.

(j) Neither the Master Servicer nor the Trustee shall (subject to Section 10.01(f)) enter into any arrangement by which any REMIC created hereunder will receive a fee or other compensation for services nor permit any REMIC created hereunder to receive any income from assets other than “qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined in Section 860G(a)(5) of the Code.

(k) Solely for purposes of Section 1.860G-1(a)(4)(iii) of the Treasury Regulations, the “latest possible maturity date” by which the principal balance of each regular interest in each REMIC would be reduced to zero is April 25, 2035, which is the Distribution Date in the month following the last scheduled payment on any Mortgage Loan.

(l) Within 30 days after the Closing Date, the REMIC Administrator shall prepare and file with the Internal Revenue Service Form 8811, “Information Return for Real Estate Mortgage Investment Conduits (REMIC) and Issuers of Collateralized Debt Obligations” for the Trust Fund.

(m) Neither the Trustee nor the Master Servicer shall sell, dispose of or substitute for any of the Mortgage Loans (except in connection with (i) the default, imminent default or foreclosure of a Mortgage Loan, including but not limited to, the acquisition or sale of a Mortgaged Property acquired by deed in lieu of foreclosure, (ii) the bankruptcy of the Trust Fund, (iii) the termination of any REMIC pursuant to Article IX of this Agreement or (iv) a purchase of Mortgage Loans pursuant to Article II or III of this Agreement) or acquire any assets for any REMIC or sell or dispose of any investments in the Custodial Account or the Certificate Account for gain, or accept any contributions to any REMIC after the Closing Date unless it has received an Opinion of Counsel that such sale, disposition, substitution or acquisition will not (a) affect adversely the status of any REMIC created hereunder as a REMIC or (b) unless the Master Servicer has determined in its sole discretion to indemnify the Trust Fund against such tax, cause any REMIC to be subject to a tax on “prohibited transactions” or “contributions” pursuant to the REMIC Provisions.

Section 10.02. Master Servicer, REMIC Administrator and Trustee Indemnification.

(a) The Trustee agrees to indemnify the Trust Fund, the Depositor, the REMIC Administrator and the Master Servicer 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 set forth in Article VIII or this Article X. In the event that Residential Funding is no longer the Master Servicer, the Trustee shall indemnify Residential Funding for any taxes and costs including, without limitation, any reasonable attorneys fees imposed on or incurred by Residential Funding as a result of a breach of the Trustee’s covenants set forth in Article VIII or this Article X.

(b) The REMIC Administrator agrees to indemnify the Trust Fund, the Depositor, the Master Servicer and the Trustee for any taxes and costs (including, without limitation, any reasonable attorneys’ fees) imposed on or incurred by the Trust Fund, the Depositor, the Master Servicer or the Trustee, as a result of a breach of the REMIC Administrator’s covenants set forth in this Article X with respect to compliance with the REMIC Provisions, including without limitation, any penalties arising from the Trustee’s execution of Tax Returns prepared by the REMIC Administrator that contain errors or omissions; provided, however, that such liability will not be imposed to the extent such breach is a result of an error or omission in information provided to the REMIC Administrator by the Master Servicer in which case Section 10.02(c) will apply.

(c) The Master Servicer agrees to indemnify the Trust Fund, the Depositor, the REMIC Administrator and the Trustee for any taxes and costs (including, without limitation, any reasonable attorneys’ fees) imposed on or incurred by the Trust Fund, the Depositor, the REMIC Administrator or the Trustee, as a result of a breach of the Master Servicer’s covenants set forth in this Article X or in Article III with respect to compliance with the REMIC Provisions, including without limitation, any penalties arising from the Trustee’s execution of Tax Returns prepared by the Master Servicer that contain errors or omissions.

ARTICLE XI

MISCELLANEOUS PROVISIONS

Section 11.01. Amendment.

(a)

This Agreement or any Custodial Agreement may be amended from time to time by the Depositor, the Master Servicer and the Trustee, without the consent of any of the Certificateholders:

(i)

to cure any ambiguity,

(ii)

to correct or supplement any provisions herein or therein, which may be inconsistent with any other provisions herein or therein or to correct any error,

(iii)

to modify, eliminate or add to any of its provisions to such extent as shall be necessary or desirable to maintain the qualification of any REMIC created hereunder as a REMIC at all times that any Certificate is outstanding or to avoid or minimize the risk of the imposition of any tax on the Trust Fund pursuant to the Code that would be a claim against the Trust Fund, provided that the Trustee has received an Opinion of Counsel to the effect that (A) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (B) such action will not adversely affect in any material respect the interests of any Certificateholder,

(iv)

to change the timing and/or nature of deposits into the Custodial Account or the Certificate Account or to change the name in which the Custodial Account is maintained, provided that (A) the Certificate Account Deposit Date shall in no event be later than the related Distribution Date, (B) such change shall not, as evidenced by an Opinion of Counsel, adversely affect in any material respect the interests of any Certificateholder and (C) such change shall not result in a reduction of the rating assigned to any Class of Certificates below the lower of the then-current rating or the rating assigned to such Certificates as of the Closing Date, as evidenced by a letter from each Rating Agency to such effect,

(v)

to modify, eliminate or add to the provisions of Section 5.02(f) or any other provision hereof restricting transfer of the Class R Certificates by virtue of their being the “residual interests” in the Trust Fund provided that (A) such change shall not result in reduction of the rating assigned to any such Class of Certificates below the lower of the then-current rating or the rating assigned to such Certificates as of the Closing Date, as evidenced by a letter from each Rating Agency to such effect, and (B) such change shall not (subject to Section 10.01(f)), as evidenced by an Opinion of Counsel (at the expense of the party seeking so to modify, eliminate or add such provisions), cause the Trust Fund or any of the Certificateholders (other than the transferor) to be subject to a federal tax caused by a transfer to a Person that is not a Permitted Transferee, or

(vi)

to make any other provisions with respect to matters or questions arising under this Agreement or such Custodial Agreement which shall not be materially inconsistent with the provisions of this Agreement, provided that such action shall not, as evidenced by an Opinion of Counsel, adversely affect in any material respect the interests of any Certificateholder and is authorized or permitted under Section 11.01.

(b)

This Agreement or any Custodial Agreement may also be amended from time to time by the Depositor, the Master Servicer, the Trustee and the Holders of Certificates evidencing in the aggregate not less than 66% of the Percentage Interests of each Class of Certificates with a Certificate Principal Balance greater than zero affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or such Custodial Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall:

(i)

reduce in any manner the amount of, or delay the timing of, payments which are required to be distributed on any Certificate without the consent of the Holder of such Certificate,

(ii)

adversely affect in any material respect the interest of the Holders of Certificates of any Class in a manner other than as described in clause (i) hereof without the consent of Holders of Certificates of such Class evidencing, as to such Class, Percentage Interests aggregating not less than 66%, or

(iii)

reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment, in any such case without the consent of the Holders of all Certificates of such Class then outstanding.

(c)

Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel (at the expense of the party seeking such amendment) to the effect that such amendment or the exercise of any power granted to the Master Servicer, the Depositor or the Trustee in accordance with such amendment will not result in the imposition of a federal tax on the Trust Fund or cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding; provided, that if the indemnity described in Section 10.01(f) with respect to any taxes that might be imposed on the Trust Fund has been given, the Trustee shall not require the delivery to it of the Opinion of Counsel described in this Section 11.01(c). The Trustee may but shall not be obligated to enter into any amendment pursuant to this Section that affects its rights, duties and immunities and this Agreement or otherwise; provided, however, such consent shall not be unreasonably withheld.

(d)

Promptly after the execution of any such amendment the Trustee shall furnish written notification of the substance of such amendment to each Certificateholder. It shall not be necessary for the consent of Certificateholders under this Section 11.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. 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)

The Depositor shall have the option, in its sole discretion, to obtain and deliver to the Trustee any corporate guaranty, payment obligation, irrevocable letter of credit, surety bond, insurance policy or similar instrument or a reserve fund, or any combination of the foregoing, for the purpose of protecting the Holders of the Class R Certificates against any or all Realized Losses or other shortfalls. Any such instrument or fund shall be held by the Trustee for the benefit of the Class R Certificateholders, but shall not be and shall not be deemed to be under any circumstances included in any REMIC. To the extent that any such instrument or fund constitutes a reserve fund for federal income tax purposes, (i) any reserve fund so established shall be an outside reserve fund and not an asset of such REMIC, (ii) any such reserve fund shall be owned by the Depositor, and (iii) amounts transferred by such REMIC to any such reserve fund shall be treated as amounts distributed by such REMIC to the Depositor or any successor, all within the meaning of Treasury regulations Section 1.860G-2(h) in effect as of the Cut-off Date. In connection with the provision of any such instrument or fund, this Agreement and any provision hereof may be modified, added to, deleted or otherwise amended in any manner that is related or incidental to such instrument or fund or the establishment or administration thereof, such amendment to be made by written instrument executed or consented to by the Depositor and such related insurer but without the consent of any Certificateholder and without the consent of the Master Servicer or the Trustee being required unless any such amendment would impose any additional obligation on, or otherwise adversely affect the interests of the Certificateholders, the Master Servicer or the Trustee, as applicable; provided that the Depositor obtains an Opinion of Counsel (which need not be an opinion of Independent counsel) to the effect that any such amendment will not cause (a) any federal tax to be imposed on the Trust Fund, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(a)(1) of the Code or on “contributions after the startup date” under Section 860G(d)(1) of the Code and (b) any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding. In the event that the Depositor elects to provide such coverage in the form of a limited guaranty provided by General Motors Acceptance Corporation, the Depositor may elect that the text of such amendment to this Agreement shall be substantially in the form attached hereto as Exhibit K (in which case Residential Funding’s Subordinate Certificate Loss Obligation as described in such exhibit shall be established by Residential Funding’s consent to such amendment) and that the limited guaranty shall be executed in the form attached hereto as Exhibit L, with such changes as the Depositor shall deem to be appropriate; it being understood that the Trustee has reviewed and approved the content of such forms and that the Trustee’s consent or approval to the use thereof is not required.

Section 11.02. Recordation of Agreement; Counterparts.

(a) 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 properties subject to the Mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Master Servicer and at its expense on direction by the Trustee (pursuant to the request of the Holders of Certificates entitled to at least 25% of the Voting Rights), but only upon direction accompanied by an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

(b) 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.

Section 11.03. Limitation on Rights of Certificateholders.

(a) The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the Trust Fund, 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 Fund, nor otherwise affect the rights, obligations and liabilities of any of the parties hereto.

(b) No Certificateholder shall have any right to vote (except as expressly provided herein) or in any manner otherwise control the operation and management of the Trust Fund, 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 constitute the Certificateholders from time to time as partners or members of an association; nor shall any Certificateholder 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 or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of Certificates of any Class evidencing in the aggregate not less than 25% of the related Percentage Interests of such Class, 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, expenses and liabilities to be incurred therein or thereby, and 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 it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates of any Class shall have any right in any manner whatever by virtue of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates of such Class or any other Class, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Agreement, except in the manner herein provided and for the common benefit of Certificateholders of such Class or all Classes, as the case may be. For the protection and enforcement of the provisions of this Section 11.03, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

With respect to any Class or Classes of Certificates issued hereunder, or any portion of any such Class, as to which the Depositor or any of its Affiliates (or any designee thereof) is the registered Holder (the “Resecuritized Certificates”), the Depositor may deposit such Resecuritized Certificates into a new REMIC, grantor trust or custodial arrangement (a “Restructuring Vehicle”) to be held by the Trustee pursuant to a Supplemental Article. The instrument adopting such Supplemental Article shall be executed by the Depositor, the Master Servicer and the Trustee; provided, that neither the Master Servicer nor the Trustee shall withhold their consent thereto if their respective interests would not be materially adversely affected thereby.

               consisting primarily of a pool of [fixed]  [adjustable]  interest
               rate,   first  [and  junior]  lien  mortgage  loans  on  one-  to
               four-family  residential  properties  sold by  RESIDENTIAL  ASSET
               SECURITIES CORPORATION

        This  Certificate  is payable  solely from the assets of the Trust Fund,  and does not
represent an  obligation  of or interest in  Residential  Asset  Securities  Corporation,  the
Master Servicer,  the Trustee  referred to below or GMAC Mortgage Group,  Inc. or any of their
affiliates.  Neither this  Certificate  nor the  underlying  Mortgage  Loans are guaranteed or
insured by any  governmental  agency or  instrumentality  or by Residential  Asset  Securities
Corporation,  the Master  Servicer,  the Trustee or GMAC Mortgage Group,  Inc. or any of their
affiliates.  None of the Depositor,  the Master Servicer,  GMAC Mortgage Group, Inc. 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 Percentage  Interest
evidenced  by this  Certificate  in  certain  distributions  with  respect  to the Trust  Fund
consisting  primarily of an interest in a pool of [fixed]  [adjustable]  interest rate,  first
lien  mortgage  loans on one- to four-  family  residential  properties,  sold by  Residential
Asset Securities  Corporation  (hereinafter  called the  "Depositor,"  which term includes any
successor entity under the Agreement  referred to below).  The Trust Fund was created pursuant
to a Pooling and Servicing  Agreement  dated as specified  above (the  "Agreement")  among the
Depositor,  the  Master  Servicer  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,  the  capitalized  terms used  herein  have the  meanings
assigned  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 the acceptance hereof assents and by which such Holder is bound.

        Pursuant to the terms of the Agreement,  a  distribution  will be made on the 25th day
of each  month  or, if such 25th day is not a  Business  Day,  the  Business  Day  immediately
following (the "Distribution Date"),  commencing as described in the Agreement,  to the Person
in whose name this  Certificate  is  registered  at the close of business on the  Business Day
immediately  preceding that Distribution Date (the "Record Date"),  from the related Available
Distribution  Amount in an amount equal to the product of the  Percentage  Interest  evidenced
by this  Certificate  and the  amount  of  interest  and  principal,  if any,  required  to be
distributed to Holders of Class A-[_] Certificates on such Distribution Date.

        Distributions  on this  Certificate  will be made either by the Master Servicer acting
on  behalf of the  Trustee  or by a Paying  Agent  appointed  by the  Trustee  in  immediately
available  funds (by wire  transfer  or  otherwise)  for the  account of the  Person  entitled
thereto if such Person shall have so notified  the Master  Servicer or such Paying  Agent,  or
by check  mailed to the  address  of the Person  entitled  thereto,  as such name and  address
shall appear on the Certificate Register.

        Notwithstanding  the above,  the final  distribution on this  Certificate will be made
after  due  notice  of the  pendency  of such  distribution  and only  upon  presentation  and
surrender  of,  this  Certificate  at the office or agency  appointed  by the Trustee for that
purpose  in  St.  Paul,   Minnesota.   The  Initial  Certificate  Principal  Balance  of  this
Certificate is set forth above. The Certificate  Principal  Balance hereof will be reduced [to
the extent of distributions  allocable to principal and any Realized Losses allocable  hereto]
[from time to time pursuant to the Agreement].

        This Certificate is one of a duly authorized  issue of Certificates  issued in several
Classes  designated as Home Equity  Mortgage  Asset-Backed  Pass-Through  Certificates  of the
Series specified hereon (herein collectively called the "Certificates").

        The  Certificates  are  limited  in  right  of  payment  to  certain  collections  and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth herein and in
the  Agreement.  In the event Master  Servicer funds are advanced with respect to any Mortgage
Loan,  such advance is  reimbursable  to the Master  Servicer,  to the extent  provided in the
Agreement,  from related  recoveries  on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

        As  provided in the  Agreement,  withdrawals  from the  Custodial  Account  and/or the
Certificate  Account  created  for  the  benefit  of  Certificateholders  may be  made  by the
Master   Servicer   from   time  to  time   for   purposes   other   than   distributions   to
Certificateholders,   such  purposes  including  without   limitation   reimbursement  to  the
Depositor and the Master Servicer of advances made, or certain  expenses  incurred,  by either
of them.

        The Agreement permits, with certain exceptions therein provided,  the amendment of the
Agreement and the  modification  of the rights and  obligations of the  Depositor,  the Master
Servicer and the Trustee and the rights of the  Certificateholders  under the  Agreement  from
time to time by the  Depositor,  the Master  Servicer  and the Trustee with the consent of the
Holders  of  Certificates  evidencing  in the  aggregate  not less than 66% of the  Percentage
Interests of each Class of  Certificates  affected thereby.  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 exchange
herefor  or in  lieu  hereof  whether  or not  notation  of such  consent  is  made  upon  the
Certificate.  The  Agreement  also  permits  the  amendment  thereof in certain  circumstances
without  the  consent of the Holders of any of the  Certificates  and,  in certain  additional
circumstances, without the consent of the Holders of certain Classes of Certificates.

        As provided in the  Agreement  and subject to certain  limitations  therein set forth,
the transfer of this  Certificate is registrable  in the  Certificate  Register upon surrender
of this Certificate for  registration of transfer at the offices or agencies  appointed by the
Trustee in St. Paul,  Minnesota,  duly  endorsed by, or  accompanied  by an  assignment in the
form below or other  written  instrument of transfer in form  satisfactory  to the Trustee and
the  Certificate  Registrar duly executed by the Holder hereof or such Holder's  attorney duly
authorized  in  writing,   and  there  upon  one  or  more  new   Certificates  of  authorized
denominations  evidencing the same Class and  aggregate  Percentage Interest will be issued to
the designated transferee or transferees.

        The  Certificates  are issuable only as  registered  Certificates  without  coupons in
Classes and in  denominations  specified in the  Agreement.  As provided in the  Agreement and
subject to certain  limitations  therein  set forth,  Certificates  are  exchangeable  for new
Certificates of authorized  denominations  evidencing the same Class and aggregate  Percentage
Interest, as requested by the Holder surrendering the same.

        No service charge will be made for any such registration of transfer or exchange,  but
the Trustee 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 Trustee,  and the Certificate  Registrar and
any agent of the Depositor,  the Master  Servicer,  the Trustee or the  Certificate  Registrar
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 Trustee or any such agent
shall be affected by notice to the contrary.

        This  Certificate  shall be governed by and construed in  accordance  with the laws of
the State of New York.

        The obligations  created by the Agreement in respect of the Certificates and the Trust
Fund created  thereby shall  terminate upon the payment to  Certificateholders  of all amounts
held  by or on  behalf  of the  Trustee  and  required  to be paid  to  them  pursuant  to the
Agreement  following  the  earlier  of (i) the  maturity  or  other  liquidation  of the  last
Mortgage Loan subject  thereto or the  disposition of all property  acquired upon  foreclosure
or deed in lieu of  foreclosure  of any Mortgage  Loan, and (ii) the purchase by the Holder of
the Class SB  Certificates  or the Master  Servicer,  as described in the Agreement,  from the
Trust  Fund of all  remaining  Mortgage  Loans and all  property  acquired  in respect of such
Mortgage Loans or the  Certificates,  in either case thereby effecting early retirement of the
Certificates.  The  Agreement  permits,  but does not  require,  the  Holder  of the  Class SB
Certificates  or the Master  Servicer,  as described in the Agreement,  (i) to purchase,  at a
price determined as provided in the Agreement,  all remaining  Mortgage Loans and all property
acquired in respect of any Mortgage Loan or (ii) to  purchase in whole,  but not in part,  all
of the  Certificates  from the  Holders  thereof,  provided,  that any such option may only be
exercised if the Stated  Principal  Balance  before giving effect to the  distributions  to be
made on such  Distribution  Date of the Mortgage Loans, as of the Distribution Date upon which
the  proceeds of any such  purchase  are  distributed  is less than ten percent of the Cut-off
Date Balance.

        Unless the certificate of  authentication  hereon has been executed by the Certificate
Registrar,  by manual  signature,  this Certificate shall not be entitled to any benefit under
the Agreement or be valid for any purpose.







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

liabilities,  claims,  costs  or  expenses  incurred  by  such  parties  as a  result  of such
acquisition or holding.

        This Certificate is one of a duly authorized  issue of Certificates  issued in several
Classes  designated as Home Equity  Mortgage  Asset-Backed  Pass-Through  Certificates  of the
Series specified hereon (herein collectively called the "Certificates").

        The  Certificates  are  limited  in  right  of  payment  to  certain  collections  and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth herein and in
the  Agreement.  In the event Master  Servicer funds are advanced with respect to any Mortgage
Loan,  such advance is  reimbursable  to the Master  Servicer,  to the extent  provided in the
Agreement,  from related  recoveries  on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

        As  provided in the  Agreement,  withdrawals  from the  Custodial  Account  and/or the
Certificate  Account created for the benefit of  Certificateholders  may be made by the Master
Servicer from time to time for purposes other than distributions to  Certificateholders,  such
purposes including without  limitation  reimbursement to the Depositor and the Master Servicer
of advances made, or certain expenses incurred, by either of them.

        The Agreement permits, with certain exceptions therein provided,  the amendment of the
Agreement and the  modification  of the rights and  obligations of the  Depositor,  the Master
Servicer and the Trustee and the rights of the  Certificateholders  under the  Agreement  from
time to time by the  Depositor,  the Master  Servicer  and the Trustee with the consent of the
Holders  of  Certificates  evidencing  in the  aggregate  not less than 66% of the  Percentage
Interests of each Class of  Certificates  affected thereby.  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 exchange
herefor  or in  lieu  hereof  whether  or not  notation  of such  consent  is  made  upon  the
Certificate.  The  Agreement  also  permits  the  amendment  thereof in certain  circumstances
without  the  consent of the Holders of any of the  Certificates  and,  in certain  additional
circumstances, without the consent of the Holders of certain Classes of Certificates.

        As provided in the  Agreement  and subject to certain  limitations  therein set forth,
the transfer of this  Certificate is registrable  in the  Certificate  Register upon surrender
of this Certificate for  registration of transfer at the offices or agencies  appointed by the
Trustee in St. Paul,  Minnesota,  duly  endorsed by, or  accompanied  by an  assignment in the
form below or other  written  instrument of transfer in form  satisfactory  to the Trustee and
the  Certificate  Registrar duly executed by the Holder hereof or such Holder's  attorney duly
authorized  in  writing,   and  there  upon  one  or  more  new   Certificates  of  authorized
denominations  evidencing the same Class and  aggregate  Percentage Interest will be issued to
the designated transferee or transferees.

        The  Certificates  are issuable only as  registered  Certificates  without  coupons in
Classes and in  denominations  specified in the  Agreement.  As provided in the  Agreement and
subject to certain  limitations  therein  set forth,  Certificates  are  exchangeable  for new
Certificates of authorized  denominations  evidencing the same Class and aggregate  Percentage
Interest, as requested by the Holder surrendering the same.

        No service charge will be made for any such registration of transfer or exchange,  but
the Trustee 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 Trustee,  and the Certificate  Registrar and
any agent of the Depositor,  the Master  Servicer,  the Trustee or the  Certificate  Registrar
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 Trustee or any such agent
shall be affected by notice to the contrary.

        This  Certificate  shall be governed by and construed in  accordance  with the laws of
the State of New York.

        The obligations  created by the Agreement in respect of the Certificates and the Trust
Fund created  thereby shall  terminate upon the payment to  Certificateholders  of all amounts
held  by or on  behalf  of the  Trustee  and  required  to be paid  to  them  pursuant  to the
Agreement  following  the  earlier  of (i) the  maturity  or  other  liquidation  of the  last
Mortgage Loan subject  thereto or the  disposition of all property  acquired upon  foreclosure
or deed in lieu of  foreclosure  of any Mortgage  Loan, and (ii) the purchase by the Holder of
the Class SB  Certificates  or the Master  Servicer,  as described in the Agreement,  from the
Trust  Fund of all  remaining  Mortgage  Loans and all  property  acquired  in respect of such
Mortgage Loans or the  Certificates,  in either case thereby effecting early retirement of the
Certificates.  The  Agreement  permits,  but does not  require,  the  Holder  of the  Class SB
Certificates  or the Master  Servicer,  as described in the Agreement,  (i) to purchase,  at a
price determined as provided in the Agreement,  all remaining  Mortgage Loans and all property
acquired in respect of any Mortgage Loan or (ii) to  purchase in whole,  but not in part,  all
of the  Certificates  from the  Holders  thereof,  provided,  that any such option may only be
exercised if the Stated  Principal  Balance  before giving effect to the  distributions  to be
made on such  Distribution  Date of the Mortgage Loans, as of the Distribution Date upon which
the  proceeds of any such  purchase  are  distributed  is less than ten percent of the Cut-off
Date Balance.

        Unless the certificate of  authentication  hereon has been executed by the Certificate
Registrar,  by manual  signature,  this Certificate shall not be entitled to any benefit under
the Agreement or be valid for any purpose.







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

               residential  properties  sold  by  RESIDENTIAL  ASSET  SECURITIES
               CORPORATION

        This  Certificate  is payable  solely from the assets of the Trust Fund,  and does not
represent an  obligation  of or interest in  Residential  Asset  Securities  Corporation,  the
Master Servicer,  the Trustee  referred to below or GMAC Mortgage Group,  Inc. or any of their

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  Percentage  Interest
evidenced  by this  Certificate  in  certain  distributions  with  respect  to the Trust  Fund
consisting  primarily of an interest in a pool of fixed  interest  rate,  first lien  mortgage
loans on one- to four- family  residential  properties,  sold by Residential  Asset Securities

under the Agreement  referred to below).  The Trust Fund was created pursuant to a Pooling and
Servicing  Agreement  dated as specified  above (the  "Agreement")  among the  Depositor,  the
Master Servicer 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,  the  capitalized  terms  used  herein  have  the  meanings  assigned  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
the acceptance hereof assents and by which such Holder is bound.

        Pursuant to the terms of the Agreement,  a  distribution  will be made on the 25th day
of each  month  or, if such 25th day is not a  Business  Day,  the  Business  Day  immediately

in whose name this  Certificate  is  registered  at the close of business on the last Business
Day of the month next  preceding  the month in which the  related  Distribution  Date  occurs,
except in the case of the first  Record  Date which  shall be the  Closing  Date (the  "Record

the  Percentage  Interest  evidenced  by this  Certificate  and the  amount  of  interest  and
principal,  if any,  required to be  distributed  to Holders of Class B  Certificates  on such

thereto if such Person shall have so notified  the Master  Servicer or such Paying  Agent,  or
by check  mailed to the  address  of the Person  entitled  thereto,  as such name and  address
shall appear on the Certificate Register.

        Notwithstanding  the above,  the final  distribution on this  Certificate will be made
after  due  notice  of the  pendency  of such  distribution  and only  upon  presentation  and
surrender  of,  this  Certificate  at the office or agency  appointed  by the Trustee for that

the extent of distributions allocable to principal and any Realized Losses allocable hereto.

        Any   Transferee   of  this  Class  B   Certificate   will  be  deemed  to  have  made
representations  relating to the  permissibility of such transfer under ERISA and Section 4975
of the  Code,  as  described  in  Section  5.02(e)(ii)  of the  Agreement.  In  addition,  any
purported  Certificate  Owner whose  acquisition or holding of this  Certificate  (or interest
therein)  was  effected  in  violation  of the  restrictions  in  Section  5.02(e)(ii)  of the
Agreement shall indemnify and hold harmless the Depositor,  the Trustee,  the Master Servicer,
any  Subservicer,   any  underwriter  and  the  Trust  Fund  from  and  against  any  and  all
liabilities,  claims,  costs  or  expenses  incurred  by  such  parties  as a  result  of such
acquisition or holding.

        This Certificate is one of a duly authorized  issue of Certificates  issued in several
Classes  designated as Home Equity  Mortgage  Asset-Backed  Pass-Through  Certificates  of the
Series specified hereon (herein collectively called the "Certificates").

        The  Certificates  are  limited  in  right  of  payment  to  certain  collections  and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth herein and in
the  Agreement.  In the event Master  Servicer funds are advanced with respect to any Mortgage
Loan,  such advance is  reimbursable  to the Master  Servicer,  to the extent  provided in the
Agreement,  from related  recoveries  on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

        As  provided in the  Agreement,  withdrawals  from the  Custodial  Account  and/or the
Certificate  Account created for the benefit of  Certificateholders  may be made by the Master
Servicer from time to time for purposes other than distributions to  Certificateholders,  such
purposes including without  limitation  reimbursement to the Depositor and the Master Servicer
of advances made, or certain expenses incurred, by either of them.

        The Agreement permits, with certain exceptions therein provided,  the amendment of the
Agreement and the  modification  of the rights and  obligations of the  Depositor,  the Master
Servicer and the Trustee and the rights of the  Certificateholders  under the  Agreement  from
time to time by the  Depositor,  the Master  Servicer  and the Trustee with the consent of the
Holders  of  Certificates  evidencing  in the  aggregate  not less than 66% of the  Percentage
Interests of each Class of Certificates  affected  thereby.  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 exchange
herefor  or in  lieu  hereof  whether  or not  notation  of such  consent  is  made  upon  the
Certificate.  The  Agreement  also  permits  the  amendment  thereof in certain  circumstances
without  the  consent of the Holders of any of the  Certificates  and,  in certain  additional
circumstances, without the consent of the Holders of certain Classes of Certificates.

        As provided in the  Agreement  and subject to certain  limitations  therein set forth,
the transfer of this  Certificate is registrable  in the  Certificate  Register upon surrender
of this Certificate for  registration of transfer at the offices or agencies  appointed by the
Trustee in St. Paul,  Minnesota,  duly  endorsed by, or  accompanied  by an  assignment in the

the  Certificate  Registrar duly executed by the Holder hereof or such Holder's  attorney duly
authorized  in  writing,   and  there  upon  one  or  more  new   Certificates  of  authorized
denominations  evidencing the same Class and aggregate  Percentage  Interest will be issued to
the designated transferee or transferees.

        The  Certificates  are issuable only as  registered  Certificates  without  coupons in
Classes and in  denominations  specified in the  Agreement.  As provided in the  Agreement and
subject to certain  limitations  therein  set forth,  Certificates  are  exchangeable  for new
Certificates of authorized  denominations  evidencing the same Class and aggregate  Percentage
Interest, as requested by the Holder surrendering the same.

        No service charge will be made for any such registration of transfer or exchange,  but
the Trustee 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 Trustee,  and the Certificate  Registrar and
any agent of the Depositor,  the Master  Servicer,  the Trustee or the  Certificate  Registrar
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 Trustee or any such agent
shall be affected by notice to the contrary.

        This  Certificate  shall be governed by and construed in  accordance  with the laws of
the State of New York.

        The obligations  created by the Agreement in respect of the Certificates and the Trust
Fund created  thereby shall  terminate upon the payment to  Certificateholders  of all amounts
held  by or on  behalf  of the  Trustee  and  required  to be paid  to  them  pursuant  to the
Agreement  following  the  earlier  of (i) the  maturity  or  other  liquidation  of the  last
Mortgage Loan subject  thereto or the  disposition of all property  acquired upon  foreclosure
or deed in lieu of  foreclosure  of any Mortgage  Loan, and (ii) the purchase by the Holder of
the Class SB  Certificates  or the Master  Servicer,  as described in the Agreement,  from the

               evidencing a percentage  interest in the distributions  allocable
               to the  Class SB-[_]  Certificates  with  respect to a Trust Fund
               consisting  primarily  of a pool  of  adjustable  interest  rate,
               first [and junior]  lien  mortgage  loans on one- to  four-family
               residential  properties  sold  by  RESIDENTIAL  ASSET  SECURITIES
               CORPORATION

        This  Certificate  is payable  solely from the assets of the Trust Fund,  and does not
represent an  obligation  of or interest in  Residential  Asset  Securities  Corporation,  the
Master  Servicer,  the Trustee  referred  to below or any of their  affiliates.  Neither  this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any  governmental
agency  or  instrumentality  or  by  Residential  Asset  Securities  Corporation,  the  Master
Servicer, the Trustee or any of their affiliates.  None of the Depositor,  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  [__________] is the registered  owner of the Percentage  Interest
evidenced  by this  Certificate  in  certain  distributions  with  respect  to the Trust  Fund
consisting  primarily  of an  interest  in a pool of  adjustable  interest  rate,  first  lien
mortgage  loans on one- to  four-family  residential  properties,  sold by  Residential  Asset
Securities   Corporation   (hereinafter  called  the  "Depositor,"  which  term  includes  any
successor entity under the Agreement  referred to below).  The Trust Fund was created pursuant
to a Pooling and Servicing  Agreement  dated as specified  above (the  "Agreement")  among the
Depositor,  the  Master  Servicer  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,  the  capitalized  terms used  herein have the
meanings  assigned 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 the acceptance hereof, assents and by which such Holder is bound.

        Pursuant to the terms of the Agreement,  a  distribution  will be made on the 25th day
of each  month  or, if such 25th day is not a  Business  Day,  the  Business  Day  immediately
following (the "Distribution Date"),  commencing as described in the Agreement,  to the Person
in whose name this  Certificate  is  registered  at the close of business on the last Business
Day of the month  immediately  preceding the month of such  distribution  (the "Record Date"),
from the  Available  Distribution  Amount in an amount equal to the product of the  Percentage
Interest  evidenced  by this  Certificate  and the amount of interest and  principal,  if any,
required to be distributed to Holders of Class SB-[_] Certificates on such Distribution Date.

        Distributions  on this  Certificate  will be made either by the Master Servicer acting
on  behalf of the  Trustee  or by a Paying  Agent  appointed  by the  Trustee  in  immediately
available  funds (by wire  transfer  or  otherwise)  for the  account of the  Person  entitled
thereto if such Person shall have so notified  the Master  Servicer or such Paying  Agent,  or
by check  mailed to the  address  of the Person  entitled  thereto,  as such name and  address
shall appear on the Certificate Register.

        Notwithstanding  the above,  the final  distribution on this  Certificate will be made
after  due  notice  of the  pendency  of such  distribution  and only  upon  presentation  and
surrender  of this  Certificate  at the office or agency  appointed  by the  Trustee  for that
purpose in St. Paul,  Minnesota.  The Notional Amount of this  Class SB-[_]  Certificate as of
any  date  of  determination   will  be  calculated  as  described  in  the  Agreement.   This
Class SB-[_]  Certificate will accrue interest at the Pass-Through Rate on the Notional Amount
as  indicated  in the  definition  of Accrued  Certificate  Interest  in the  Agreement.  This
Class SB-[_] Certificate will not accrue interest on its Certificate Principal Balance.

        No transfer of this  Certificate  will be made unless such transfer is exempt from the
registration  requirements  of the  Securities  Act of 1933,  as amended,  and any  applicable
state  securities  laws or is made in  accordance  with said Act and laws.  In the event  that
such a transfer  is to be made,  (i) the  Trustee or the  Depositor  may require an opinion of
counsel  acceptable  to and  in  form  and  substance  satisfactory  to the  Trustee  and  the
Depositor  that such transfer is exempt  (describing  the  applicable  exemption and the basis
therefor) from or is being made pursuant to the  registration  requirements  of the Securities
Act of 1933, as amended,  and of any  applicable  statute of any state and (ii) the transferee
shall  execute  an  investment  letter in the form  described  by the  Agreement.  The  Holder
hereof  desiring to effect  such  transfer  shall,  and does hereby  agree to,  indemnify  the
Trustee,  the Depositor,  the Master Servicer and the Certificate  Registrar  acting on behalf
of the Trustee  against any  liability  that may result if the transfer is not so exempt or is
not made in accordance with such Federal and state laws.

        No transfer of this  Certificate or any interest therein shall be made to any employee
benefit plan or other plan or  arrangement  subject to the prohibited  transaction  provisions
of  ERISA  or  Section  4975 of the  Code,  or any  person  (including  an  insurance  company
investing its general account,  an investment  manager,  a named fiduciary or a trustee of any
such plan) who is using  "plan  assets" of any such plan to effect such  acquisition  (each of
the foregoing,  a "Plan Investor")  unless the Trustee,  the Depositor and the Master Servicer
are provided with either (i) a certification  pursuant to Section  5.02(e)(i) of the Agreement
or (ii) an Opinion of Counsel  acceptable  to and in form and  substance  satisfactory  to the
Trustee,  the Depositor and the Master  Servicer to the effect that the purchase or holding of
this  Certificate is permissible  under  applicable  law, will not constitute or result in any
non-exempt  prohibited  transaction under Section 406 of ERISA or Section 4975 of the Code (or
comparable  provisions of any subsequent  enactments),  and will not subject the Trustee,  the
Depositor or the Master  Servicer to any  obligation or liability  (including  obligations  or
liabilities  under ERISA or Section 4975 of the Code) in addition to those  undertaken  in the
Agreement,  which Opinion of Counsel shall not be an expense of the Trustee,  the Depositor or
the Master Servicer.

        This Certificate is one of a duly authorized  issue of Certificates  issued in several
Classes  designated as Home Equity  Mortgage  Asset-Backed  Pass-Through  Certificates  of the
Series specified hereon (herein collectively called the "Certificates").

        The  Certificates  are  limited  in  right  of  payment  to  certain  collections  and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth herein and in
the  Agreement.  In the event Master  Servicer funds are advanced with respect to any Mortgage
Loan,  such advance is  reimbursable  to the Master  Servicer,  to the extent  provided in the
Agreement,  from related  recoveries  on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

        As  provided in the  Agreement,  withdrawals  from the  Custodial  Account  and/or the
Certificate  Account  created  for  the  benefit  of  Certificateholders  may be  made  by the
Master   Servicer   from   time  to  time   for   purposes   other   than   distributions   to
Certificateholders,   such  purposes  including  without   limitation   reimbursement  to  the
Depositor and the Master Servicer of advances made, or certain  expenses  incurred,  by either
of them.

        The Agreement permits, with certain exceptions therein provided,  the amendment of the
Agreement and the  modification  of the rights and  obligations of the  Depositor,  the Master
Servicer and the Trustee and the rights of the  Certificateholders  under the  Agreement  from
time to time by the  Depositor,  the Master  Servicer  and the Trustee with the consent of the
Holders  of  Certificates  evidencing  in the  aggregate  not less than 66% of the  Percentage
Interests of each Class of  Certificates  affected thereby.  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 exchange
herefor  or in  lieu  hereof  whether  or not  notation  of such  consent  is  made  upon  the
Certificate.  The  Agreement  also  permits  the  amendment  thereof in certain  circumstances
without  the  consent of the Holders of any of the  Certificates  and,  in certain  additional
circumstances, without the consent of the Holders of certain Classes of Certificates.

        As provided in the  Agreement  and subject to certain  limitations  therein set forth,
the transfer of this  Certificate is registrable  in the  Certificate  Register upon surrender
of this Certificate for  registration of transfer at the offices or agencies  appointed by the
Trustee in St. Paul,  Minnesota,  duly  endorsed by, or  accompanied  by an  assignment in the
form below or other  written  instrument of transfer in form  satisfactory  to the Trustee and
the  Certificate  Registrar duly executed by the Holder hereof or such Holder's  attorney duly
authorized  in  writing,   and  thereupon   one  or  more  new   Certificates   of  authorized
denominations  evidencing the same Class and  aggregate  Percentage Interest will be issued to
the designated transferee or transferees.

        The  Certificates  are issuable only as  registered  Certificates  without  coupons in
Classes and in  denominations  specified in the  Agreement.  As provided in the  Agreement and
subject to certain  limitations  therein  set forth,  Certificates  are  exchangeable  for new
Certificates of authorized  denominations  evidencing the same Class and aggregate  Percentage
Interest, as requested by the Holder surrendering the same.

        No service charge will be made for any such registration of transfer or exchange,  but
the Trustee 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 Trustee,  the Certificate  Registrar and any
agent of the Depositor,  the Master  Servicer,  the Trustee or the  Certificate  Registrar 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  Trustee or any such agent
shall be affected by notice to the contrary.

        This  Certificate  shall be governed by and construed in  accordance  with the laws of
the State of New York.

        The obligations  created by the Agreement in respect of the Certificates and the Trust
Fund created  thereby shall  terminate upon the payment to  Certificateholders  of all amounts
held  by or on  behalf  of the  Trustee  and  required  to be paid  to  them  pursuant  to the
Agreement  following  the  earlier  of (i) the  maturity  or  other  liquidation  of the  last
Mortgage Loan subject  thereto or the  disposition of all property  acquired upon  foreclosure
or deed in lieu of  foreclosure  of any Mortgage  Loan, and (ii) the purchase by the Holder of
the Class SB  Certificates  or the Master  Servicer,  as described in the Agreement,  from the
Trust  Fund of all  remaining  Mortgage  Loans and all  property  acquired  in respect of such
Mortgage Loans or the  Certificates,  in either case thereby effecting early retirement of the
Certificates.  The  Agreement  permits,  but does not  require,  the  Holder  of the  Class SB
Certificates  or the Master  Servicer,  as described in the Agreement,  (i) to purchase,  at a
price determined as provided in the Agreement,  all remaining  Mortgage Loans and all property
acquired in respect of any Mortgage Loan or (ii) to  purchase in whole,  but not in part,  all
of the  Certificates  from the  Holders  thereof,  provided,  that any such option may only be
exercised if the Stated  Principal  Balance  before giving effect to the  distributions  to be
made on such  Distribution  Date of the Mortgage Loans, as of the Distribution Date upon which
the  proceeds of any such  purchase  are  distributed  is less than ten percent of the Cut-off
Date Balance.

        Unless the certificate of  authentication  hereon has been executed by the Certificate
Registrar by manual  signature,  this  Certificate  shall not be entitled to any benefit under
the Agreement or be valid for any purpose.







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

               evidencing a percentage  interest in the distributions  allocable
               to the  Class R-[_]  Certificates  with  respect  to a Trust Fund
               consisting  primarily  of mortgage  loans on one- to  four-family
               residential  properties  sold  by  RESIDENTIAL  ASSET  SECURITIES
               CORPORATION

        This  Certificate  is  payable  solely  from the assets of the Trust Fund and does not
represent an  obligation  of or interest in  Residential  Asset  Securities  Corporation,  the
Master  Servicer,  the Trustee  referred  to below or any of their  affiliates.  Neither  this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any  governmental
agency  or  instrumentality  or  by  Residential  Asset  Securities  Corporation,  the  Master
Servicer, the Trustee or any of their affiliates.  None of the Depositor,  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 [Residential  Funding  Corporation] is the registered owner of the
Percentage  Interest  evidenced by this Certificate in certain  distributions  with respect to
the Trust Fund consisting  primarily of a pool of adjustable  rate,  first lien mortgage loans
on one- to four-family  residential  properties  (the "Mortgage  Loans"),  sold by Residential
Asset Securities  Corporation  (hereinafter  called the  "Depositor,"  which term includes any
successor entity under the Agreement  referred to below).  The Trust Fund was created pursuant
to a Pooling and  Servicing  Agreement  dated as specified  above (the  "Agreement)  among the
Depositor,  the  Master  Servicer  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,  the  capitalized  terms used  herein  have the  meanings
assigned  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 the acceptance hereof assents and by which such Holder is bound.

        Pursuant to the terms of the Agreement,  a  distribution  will be made on the 25th day
of each  month  or, if such 25th day is not a  Business  Day,  the  Business  Day  immediately
following (the "Distribution Date"),  commencing as described in the Agreement,  to the Person
in whose name this  Certificate  is  registered  at the close of business on the last Business
Day of the month  immediately  preceding the month of such  distribution  (the "Record Date"),
from the  related  Available  Distribution  Amount in an amount  equal to the  product  of the
Percentage  Interest  evidenced by this Certificate and, the amount of interest and principal,
if any,  required  to be  distributed  to the  Holders  of  Class R-[_]  Certificates  on such
Distribution Date.

        Each  Holder of this  Certificate  will be  deemed  to have  agreed to be bound by the
restrictions  set  forth in the  Agreement  to the  effect  that (i) each  person  holding  or
acquiring  any  Ownership  Interest in this  Certificate  must be a United States Person and a
Permitted  Transferee,  (ii) the transfer of any Ownership  Interest in this  Certificate will
be  conditioned  upon the delivery to the Trustee of, among other things,  an affidavit to the
effect that it is a United  States  Person and  Permitted  Transferee,  (ii) 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  Master  Servicer  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  Master  Servicer,  which  purchaser  may  be the  Master  Servicer,  or any
affiliate of the Master  Servicer,  on such terms and  conditions  as the Master  Servicer may
choose.

        Notwithstanding  the above,  the final  distribution on this  Certificate will be made
after  due  notice  of the  pendency  of such  distribution  and only  upon  presentation  and
surrender  of this  Certificate  at the office or agency  appointed  by the  Trustee  for that
purpose  in  St.  Paul,  Minnesota.  The  Holder  of  this  Certificate  may  have  additional
obligations with respect to this Certificate, including tax liabilities.

        No  transfer of this  Class R-[_]  Certificate  will be made  unless such  transfer is
exempt from the registration  requirements of the Securities Act of 1933, as amended,  and any
applicable  state  securities  laws or is made in  accordance  with said Act and laws.  In the
event that such a transfer  is to be made,  (i) the  Trustee or the  Depositor  may require an
opinion of counsel  acceptable  to and in form and substance  satisfactory  to the Trustee and
the  Depositor  that such  transfer is exempt  (describing  the  applicable  exemption and the
basis  therefor)  from or is being  made  pursuant  to the  registration  requirements  of the
Securities Act of 1933, as amended,  and of any  applicable  statute of any state and (ii) the
transferee  shall execute an investment  letter in the form  described by the  Agreement.  The
Holder hereof  desiring to effect such  transfer  shall,  and does hereby agree to,  indemnify
the Trustee,  the  Depositor,  the Master  Servicer and the  Certificate  Registrar  acting on
behalf of the Trustee  against any liability  that may result if the transfer is not so exempt
or is not made in accordance with such Federal and state laws.

        No transfer of this  Certificate or any interest therein shall be made to any employee
benefit plan or other plan or  arrangement  subject to the prohibited  transaction  provisions
of  ERISA  or  Section  4975 of the  Code,  or any  person  (including  an  insurance  company
investing its general account,  an investment  manager,  a named fiduciary or a trustee of any
such plan) who is using  "plan  assets" of any such plan to effect such  acquisition  (each of
the foregoing,  a "Plan Investor")  unless the Trustee,  the Depositor and the Master Servicer
are provided with either (i) a certification  pursuant to Section  5.02(e)(i) of the Agreement
or (ii) an Opinion of Counsel  acceptable  to and in form and  substance  satisfactory  to the
Trustee,  the Depositor and the Master  Servicer to the effect that the purchase or holding of
this  Certificate is permissible  under  applicable  law, will not constitute or result in any
non-exempt  prohibited  transaction under Section 406 of ERISA or Section 4975 of the Code (or
comparable  provisions of any subsequent  enactments),  and will not subject the Trustee,  the
Depositor or the Master  Servicer to any  obligation or liability  (including  obligations  or
liabilities  under ERISA or Section 4975 of the Code) in addition to those  undertaken  in the
Agreement,  which Opinion of Counsel shall not be an expense of the Trustee,  the Depositor or
the Master Servicer.

        This Certificate is one of a duly authorized  issue of Certificates  issued in several
Classes  designated as Home Equity  Mortgage  Asset-Backed  Pass-Through  Certificates  of the
Series specified hereon (herein collectively called the "Certificates").

        The  Certificates  are  limited  in  right  of  payment  to  certain  collections  and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth herein and in
the  Agreement.  In the event Master  Servicer funds are advanced with respect to any Mortgage
Loan,  such advance is  reimbursable  to the Master  Servicer,  to the extent  provided in the
Agreement,  from related  recoveries  on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

        As  provided in the  Agreement,  withdrawals  from the  Custodial  Account  and/or the
Certificate  Account  created  for  the  benefit  of  Certificateholders  may be  made  by the
Master   Servicer   from   time  to  time   for   purposes   other   than   distributions   to
Certificateholders,   such  purposes  including  without   limitation   reimbursement  to  the
Depositor and the Master Servicer of advances made, or certain  expenses  incurred,  by either
of them.

        The Agreement permits, with certain exceptions therein provided,  the amendment of the
Agreement and the  modification  of the rights and  obligations of the  Depositor,  the Master
Servicer and the Trustee and the rights of the  Certificateholders  under the  Agreement  from
time to time by the  Depositor,  the Master  Servicer  and the Trustee with the consent of the
Holders  of  Certificates  evidencing  in the  aggregate  not less than 66% of the  Percentage
Interests of each Class of  Certificates  affected thereby.  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 exchange
herefor  or in  lieu  hereof  whether  or not  notation  of such  consent  is  made  upon  the
Certificate.  The  Agreement  also  permits  the  amendment  thereof in certain  circumstances
without  the  consent of the Holders of any of the  Certificates  and,  in certain  additional
circumstances, without the consent of the Holders of certain Classes of Certificates.

        As provided in the  Agreement  and subject to certain  limitations  therein set forth,
the transfer of this  Certificate is registrable  in the  Certificate  Register upon surrender
of this Certificate for  registration of transfer at the offices or agencies  appointed by the
Trustee in St. Paul,  Minnesota,  duly  endorsed by, or  accompanied  by an  assignment in the
form below or other  written  instrument of transfer in form  satisfactory  to the Trustee and
the  Certificate  Registrar duly executed by the Holder hereof or such Holder's  attorney duly
authorized  in  writing,   and  thereupon   one  or  more  new   Certificates   of  authorized
denominations  evidencing the same Class and  aggregate  Percentage Interest will be issued to
the designated transferee or transferees.

        The  Certificates  are issuable only as  registered  Certificates  without  coupons in
Classes and in  denominations  specified in the  Agreement.  As provided in the  Agreement and
subject to certain  limitations  therein  set forth,  Certificates  are  exchangeable  for new
Certificates of authorized  denominations  evidencing the same Class and aggregate  Percentage
Interest, as requested by the  Holder surrendering the same.

        No service charge will be made for any such registration of transfer or exchange,  but
the Trustee 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 Trustee,  the Certificate  Registrar and any
agent of the Depositor,  the Master  Servicer,  the Trustee or the  Certificate  Registrar 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  Trustee or any such agent
shall be affected by notice to the contrary.

        This  Certificate  shall be governed by and construed in  accordance  with the laws of
the State of New York.

        The obligations  created by the Agreement in respect of the Certificates and the Trust
Fund created  thereby shall  terminate upon the payment to  Certificateholders  of all amounts
held  by or on  behalf  of the  Trustee  and  required  to be paid  to  them  pursuant  to the
Agreement.

        Unless the certificate of  authentication  hereon has been executed by the Certificate
Registrar,  by manual  signature,  this Certificate shall not be entitled to any benefit under
the Agreement or be valid for any purpose.







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

                                 W I T N E S S E T H T H A T:

               WHEREAS, the Company, the Master Servicer,  and the Trustee have entered into a
Pooling and  Servicing  Agreement,  dated as of  April 1,  2005,  relating to the  issuance of
Residential  Asset  Securities  Corporation,  Home Equity Mortgage  Asset-Backed  Pass-Through

Pooling  Agreement,"  and as  amended  and  supplemented  from  time  to  time,  the  "Pooling
Agreement"); and

               WHEREAS,  the  Custodian  has  agreed to act as agent for the  Trustee  for the
purposes of receiving and holding  certain  documents and other  instruments  delivered by the
Company  and the  Master  Servicer  under  the  Pooling  Agreement,  all  upon the  terms  and

               NOW,  THEREFORE,  in consideration of the premises and the mutual covenants and
agreements  hereinafter  set forth,  the  Trustee,  the Company,  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  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 Company and the
Master  Servicer hereby direct the Trustee to appoint Wells Fargo Bank,  National  Association
as the Custodian  hereunder.  The Custodian,  as the duly  appointed  agent of the Trustee for
these  purposes,  acknowledges  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 the 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 the related  Mortgage  Loans to the Trustee that have not been  recorded,  each
such  assignment  shall be  delivered  by the  Custodian  to the  Company  for the  purpose of
recording it in the appropriate public office for real property records,  and the Company,  at
no expense to the Custodian,  shall promptly  cause to be recorded in the  appropriate  public
office for real property  records each such  assignment  and,  upon receipt  thereof from such
public office, shall return each such assignment to the Custodian.

Section 2.3....Review of Mortgage Files.

(a)     On or prior to the  Closing  Date,  the  Custodian  shall  deliver  to the  Trustee an
Initial  Certification in the form annexed hereto as Annex I evidencing  receipt of a Mortgage
File for each  Mortgage  Loan  listed on the  Schedule  attached  hereto (the  "Mortgage  Loan
Schedule").  The parties hereto  acknowledge that certain documents  referred to in Subsection
2.01(b)(i)  of the Pooling  Agreement  may be missing on or prior to the Closing Date and such
missing documents shall be listed on Schedule A to Annex I.

(b)     Within 90 days after 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  Agreement  each Mortgage File and to deliver to the Trustee an Interim  Certification
in the form  annexed  hereto  as Annex II to the  effect  that all  documents  required  to be
delivered  pursuant  to Section  2.01 (b) of the  Pooling  Agreement  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.  For  purposes of such  review,  the  Custodian  shall  compare  the  following
information  in each  Mortgage  File to the  corresponding  information  in the Mortgage  Loan
Schedule:  (i) the loan  number,  (ii) the  borrower  name and  (iii) the  original  principal
balance.  In the event that any Mortgage Note or Assignment of Mortgage has been  delivered to
the  Custodian  by the Company in blank,  the  Custodian,  upon the  direction of the Company,
shall cause each such  Mortgage  Note to be  endorsed to the Trustee and each such  Assignment
of  Mortgage  to be  completed  in the name of the  Trustee  prior  to the date on which  such
Interim  Certification  is  delivered  to the  Trustee.  Within  45  days  of  receipt  of the
documents required to be delivered  pursuant to Section 2.01(c) of the Pooling Agreement,  the
Custodian  agrees,  for the benefit of the  Certificateholders,  to review each document,  and
upon the written  request of the  Trustee to deliver to the  Trustee an updated  Schedule A to
the 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,  or that the MIN is  accurate.  If in  performing  the  review  required  by this
Section 2.3 the Custodian  finds any document or documents  constituting  a part of a Mortgage
File to be  missing  or  defective  in  respect of the items  reviewed  as  described  in this
Section 2.3(b),  the Custodian  shall promptly so notify the Company,  the Master Servicer and
the Trustee.

(c)     Upon  receipt of all  documents  required to be in the  Mortgage  Files the  Custodian
shall  deliver to the Trustee a Final  Certification  in the form annexed  hereto as Annex III
evidencing the completeness of the Mortgage Files.

               Upon receipt of written  request  from the  Trustee,  the Company or the Master
Servicer,  the Custodian  shall as soon as  practicable  supply the Trustee with a list of all
of the documents  relating to the Mortgage Loans required to be delivered  pursuant to Section
2.01 (b) of the Pooling Agreement not then contained in the Mortgage Files.

Section 2.4....Notification of Breaches of  Representations  and Warranties.  If the Custodian
discovers,  in the course of performing its custodial functions,  a breach of a representation
or warranty made by the Master  Servicer or the Company as set forth in the Pooling  Agreement
with respect to a Mortgage Loan relating to a Mortgage File,  the Custodian  shall give prompt
written notice to the Company, the Master Servicer and the Trustee.

Section 2.5....Custodian to  Cooperate:  Release of Mortgage  Files.  Upon the  repurchase  or
substitution  of any Mortgage Loan pursuant to Article II of the Pooling  Agreement or payment
in full of any Mortgage  Loan, or the receipt by the Master  Servicer of a  notification  that
payment  in full  will be  escrowed  in a manner  customary  for  such  purposes,  the  Master
Servicer shall  immediately  notify the Custodian by delivering to the Custodian a Request for
Release (in the form of Annex IV attached  hereto or a mutually  acceptable  electronic  form)
and shall request delivery to it of the Mortgage File. The Custodian  agrees,  upon receipt of
such Request for  Release,  promptly to release to the Master  Servicer  the related  Mortgage
File.  Upon receipt of a Request for Release from the Master  Servicer,  signed by a Servicing
Officer,  that (i) the  Master  Servicer  or a  Subservicer,  as the  case may be,  has made a
deposit  into the  Certificate  Account in payment for the  purchase  of the related  Mortgage
Loan in an amount equal to the Purchase  Price for such  Mortgage Loan or (ii) the Company has
chosen to  substitute  a  Qualified  Substitute  Mortgage  Loan for such  Mortgage  Loan,  the
Custodian  shall  release to the Master  Servicer  the related  Mortgage  File.  Upon  written
notification  of a  substitution,  the Master  Servicer 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  Qualified  Substitute  Mortgage  Loan,  upon  receiving  written
notification from the Master Servicer of such substitution.

               From time to time as is appropriate  for the servicing or  foreclosures  of any
Mortgage Loan, including,  for this purpose,  collection under any Primary Insurance Policy or
any Mortgage  Pool  Insurance  Policy,  the Master  Servicer  shall deliver to the Custodian a
Request  for  Release  certifying  as to the  reason  for such  release.  Upon  receipt of the
foregoing,  the  Custodian  shall  deliver the  Mortgage  File or such  document to the Master
Servicer.  The Master  Servicer  shall cause each  Mortgage  File or any  document  therein so
released to be  returned to the  Custodian  when the need  therefor by the Master  Servicer no
longer exists,  unless (i) the Mortgage Loan has been liquidated and the Liquidation  Proceeds
relating  to the  Mortgage  Loan have been  deposited  in the  Custodial  Account  or (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 Master Servicer has delivered to the Custodian an updated Request
for  Release  signed by 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.  Immediately  upon  receipt of any Mortgage  File  returned to the
Custodian by the Master Servicer,  the Custodian shall deliver a signed  acknowledgment to the
Master Servicer, confirming receipt of such Mortgage File.

               Upon the request of the Master Servicer,  the Custodian will send to the Master
Servicer copies of any documents contained in the Mortgage File.

Section 2.6....Assumption   Agreements.   In  the  event  that  any  assumption  agreement  or
substitution  of  liability  agreement  is  entered  into with  respect to any  Mortgage  Loan
subject  to this  Agreement  in  accordance  with the  terms  and  provisions  of the  Pooling
Agreement,   the  Master   Servicer  shall  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  a 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 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.  Except  upon  compliance  with the
applicable  provisions of Article II of this  Agreement,  no Mortgage Note,  Mortgage or other
document  constituting  a part of a Mortgage  File shall be delivered by the  Custodian to the
Company or the Master Servicer or otherwise released from the possession of the Custodian.

               The Master  Servicer shall promptly notify the Custodian in writing if it shall
no longer be a member of MERS,  or if it otherwise  shall no longer be capable of  registering
and recording  Mortgage Loans using MERS. In addition,  the Master Servicer shall (i) promptly
notify the  Custodian in writing when a MERS Mortgage  Loan is no longer  registered  with and
recorded  under MERS and (ii)  concurrently  with any such  deregistration  of a MERS Mortgage
Loan,  prepare,  execute  and  record an  original  assignment  from MERS to the  Trustee  and
deliver such assignment to the Custodian.

Section 3.2....Indemnification.   The  Company   hereby  agrees  to  indemnify  and  hold  the
Custodian  harmless  from and against  all  claims,  liabilities,  losses,  actions,  suits or
proceedings at law or in equity,  or any other  expenses,  fees or charges of any character or
nature,  which the  Custodian  may incur or with  which the  Custodian  may be  threatened  by
reason of its acting as  custodian  under this  Agreement,  including  indemnification  of the
Custodian  against  any  and all  expenses,  including  attorney's  fees  if  counsel  for the
Custodian  has been  approved by the Company,  and the cost of defending  any action,  suit or
proceedings  or  resisting  any  claim.  Notwithstanding  the  foregoing,  it is  specifically
understood  and agreed  that in the event any such claim,  liability,  loss,  action,  suit or
proceeding or other  expense,  fee or charge shall have been caused by reason of any negligent
act,  negligent  failure to act or willful  misconduct on the part of the Custodian,  or which
shall constitute a willful breach of its duties hereunder,  the indemnification  provisions of
this Agreement shall not apply.

Section 3.3....Custodian May Own  Certificates.  The Custodian in its  individual or any other
capacity  may become the owner or pledgee of  Certificates  with the same rights it would have
if it were not Custodian.

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.

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 notice of resignation,
the Trustee  shall  either take custody of the  Mortgage  Files itself and give prompt  notice
thereof  to the  Company,  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
notice  of  resignation,   the  resigning  Custodian  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor Custodian.

               The  Trustee,  at the  direction of the Master  Servicer  and the Company,  may
remove the Custodian at any time.  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 and shall be able to satisfy the other  requirements  contained in Section
3.7 and shall be unaffiliated with the Master Servicer or the Company.

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

                                   Miscellaneous Provisions

Section 4.1....Notices. All notices,  requests,  consents and demands and other communications
required  under this  Agreement  or pursuant  to any other  instrument  or document  delivered
hereunder shall be in writing and, unless otherwise  specifically  provided,  may be delivered
personally,  by telegram or telex,  or by  registered  or  certified  mail,  postage  prepaid,
return  receipt  requested,  at the addresses  specified on the signature  page hereof (unless
changed  by the  particular  party  whose  address  is  stated  herein  by  similar  notice in
writing); in each case the notice will be deemed delivered when received.

Section 4.2....Amendments.  No  modification  or amendment of or supplement to this  Agreement
shall be valid or  effective  unless the same is in writing and signed by all parties  hereto,
and none of the Company,  the Master  Servicer or the Trustee  shall enter into any  amendment
hereof except as permitted by the Pooling  Agreement.  The Trustee shall give prompt notice to
the  Custodian  of any  amendment  or  supplement  to the  Pooling  Agreement  and furnish the
Custodian with written copies thereof.

Section 4.3....GOVERNING  LAW. THIS  AGREEMENT  SHALL BE DEEMED A CONTRACT MADE UNDER THE LAWS
OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCED IN  ACCORDANCE  WITH AND GOVERNED
BY THE LAWS OF THE STATE OF NEW YORK.

Section 4.4....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
properties  subject  to the  Mortgages  are  situated,  and in any  other  appropriate  public
recording  office or elsewhere,  such recordation to be effected by the Master Servicer and at
its expense on  direction by the Trustee  (pursuant to the request of holders of  Certificates
evidencing  undivided  interests in the aggregate of not less than 25% of the Trust Fund), but
only upon  direction  accompanied  by an  Opinion of Counsel  reasonably  satisfactory  to the
Master  Servicer  to the effect  that the  failure  to effect  such  recordation  is likely to
materially and adversely affect the interests of the Certificateholders.

               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.

Section 4.5....Severability  of Provisions.  If any one or more of the covenants,  agreements,
provisions or terms of this Agreement shall be for any reason  whatsoever  held invalid,  then
such covenants,  agreements,  provisions or terms shall be deemed severable from the remaining
covenants,  agreements,  provisions or terms of this  Agreement and shall in no way affect the
validity or  enforceability  of the other  provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

                           FORM OF TRANSFER AFFIDAVIT AND AGREEMENT

STATE OF                )
                        )ss.:
COUNTY OF               )


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

1.      That he is [Title of Officer] of [Name of Owner]  (record or  beneficial  owner of the
Home Equity Mortgage  Asset-Backed  Pass-Through  Certificates,  Series  2005-KS4,  Class R-__
(the "Owner")),  a [savings  institution]  [corporation] duly organized and existing under the
laws of [the  State of  ________________]  [the  United  States],  on behalf of which he makes
this affidavit and agreement.

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

3.      That  the  Owner is  aware  (i) of the tax that  would  be  imposed  on  transfers  of
Class R-__  Certificates to disqualified  organizations or an electing large partnership under
the Code,  that applies to all  transfers  of  Class R-__  Certificates  after March 31, 1988;
(ii) that such tax would be on the  transferor  (or,  with  respect to  transfers  to electing
large  partnerships,  on each such  partnership),  or, if such  transfer  is  through an agent
(which person  includes a broker,  nominee or middleman) for a disqualified  organization,  on
the agent;  (iii) that the person  (other than with  respect to  transfers  to electing  large
partnerships)  otherwise  liable for the tax shall be relieved of liability for the tax if the
transferee  furnishes to such person an affidavit  that the  transferee is not a  disqualified
organization  and, at the time of transfer,  such person does not have actual  knowledge  that
the  affidavit  is  false;  and (iv)  that the  Class R-__  Certificates  may be  "noneconomic
residual  interests" within the meaning of Treasury  regulations  promulgated  pursuant to the
Code and that the  transferor  of a noneconomic  residual  interest will remain liable for any
taxes  due with  respect  to the  income on such  residual  interest,  unless  no  significant
purpose of the transfer was to impede the assessment or collection of tax.

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

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

6.      That the Owner has reviewed the  restrictions set forth on the face of the Class R -__
Certificates  and the  provisions of Section  5.02(f) of the Pooling and  Servicing  Agreement
under which the  Class R-__  Certificates  were issued (in  particular,  clause  (iii)(A)  and
(iii)(B)  of Section  5.02(f)  which  authorize  the  Trustee to deliver  payments to a person
other than the Owner and  negotiate  a  mandatory  sale by the  Trustee in the event the Owner
holds such  Certificates in violation of Section  5.02(f)).  The Owner expressly  agrees to be
bound by and to comply with such restrictions and provisions.

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

8.      The Owner's Taxpayer Identification Number is ____________________.

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

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

11.     That the Owner has no present  knowledge or expectation  that it will be unable to pay
any United States taxes owed by it so long as any of the Certificates remain  outstanding.  In
this  regard,  the Owner hereby  represents  to and for the benefit of the person from whom it
acquired  the  Class R-__  Certificate  that the Owner  intends to pay taxes  associated  with
holding  such  Class R-__  Certificate  as they become due,  fully  understanding  that it may
incur tax liabilities in excess of any cash flows generated by the Class R-__ Certificate.

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

13.     The  Owner  is  either  (i) a  citizen  or  resident  of  the  United  States,  (ii) a
corporation,  partnership or other entity  treated as a corporation or a partnership  for U.S.
federal  income tax  purposes  and created or  organized  in, or under the laws of, the United
States,  any state thereof or the District of Columbia  (other than a partnership  that is not
treated  as a United  States  person  under any  applicable  Treasury  regulations),  (iii) an
estate  that is  described  in  Section  7701(a)(30)(D)  of the Code,  or (iv) a trust that is
described in Section 7701(a)(30)(E) of the Code.

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

15.     The Owner  hereby  certifies,  represents  and  warrants  to, and  covenants  with the
Depositor,  the Trustee and the Master  Servicer that the  following  statements in (a) or (b)
are accurate:

               (a)    The  Certificates are not being acquired by, and will not be transferred
    to, any  employee  benefit  plan or other plan or  arrangement  subject to the  prohibited
    transaction  provisions of the Employee Retirement Income Security Act of 1974, as amended
    ("ERISA"),  or Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code"),
    or  any  person  (including  an  insurance  company  investing  its  general  account,  an
    investment  manager,  a named  fiduciary or a trustee of any such plan) who is using "plan
    assets"  of any such plan to  effect  such  acquisition  (each of the  foregoing,  a "Plan
    Investor").; or

               (b)    The Owner  has  provided  the  Trustee,  the  Depositor  and the  Master
    Servicer with an Opinion of Counsel  acceptable to and in form and substance  satisfactory
    to the Trustee,  the Depositor and the Master  Servicer to the effect that the purchase or
    holding of  Certificates  is  permissible  under  applicable  law, will not  constitute or
    result in any  non-exempt  prohibited  transaction  under  Section 406 of ERISA or Section
    4975 of the Code (or  comparable  provisions of any subsequent  enactments),  and will not
    subject the Trustee, the Depositor,  or the Master Servicer to any obligation or liability
    (including  obligations  or  liabilities  under  ERISA  or  Section 4975  of the  Code) in
    addition to those  undertaken  in the Pooling and  Servicing  Agreement,  which Opinion of
    Counsel shall not be at the expense of the Trustee, the Depositor or the Master Servicer.

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

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







        IN WITNESS  WHEREOF,  the Owner has  caused  this  instrument  to be  executed  on its
behalf,  pursuant to the  authority of its Board of  Directors,  by its [Title of Officer] and

Background

        This document contains final regulations  regarding the proposed  amendments to 26 CFR
part 1 under section 860E of the Internal  Revenue Code (Code).  The  regulations  provide the
circumstances  under which a transferor of a noneconomic  REMIC residual  interest meeting the
investigation  and  representation  requirements  may  avail  itself  of the  safe  harbor  by
satisfying either the formula test or the asset test.

        Final  regulations  governing  REMICs,  issued in 1992,  contain  rules  governing the
transfer of noneconomic  REMIC  residual  interests.  In general,  a transfer of a noneconomic
residual  interest  is  disregarded  for all tax  purposes  if a  significant  purpose  of the
transfer  is to enable  the  transferor  to impede  the  assessment  or  collection  of tax. A
purpose to impede the  assessment  or  collection  of tax (a wrongful  purpose)  exists if the
transferor,  at the  time  of the  transfer,  either  knew  or  should  have  known  that  the
transferee  would be unwilling or unable to pay taxes due on its share of the REMIC's  taxable
income.  Under a safe harbor,  the  transferor  of a REMIC  noneconomic  residual  interest is
presumed  not to  have  a  wrongful  purpose  if  two  requirements  are  satisfied:  (1)  the
transferor  conducts a reasonable  investigation of the transferee's  financial condition (the
investigation  requirement);  and  (2)  the  transferor  secures  a  representation  from  the
transferee to the effect that the transferee  understands the tax obligations  associated with
holding a residual interest and intends to pay those taxes (the representation requirement).

        The IRS and  Treasury  have  been  concerned  that  some  transferors  of  noneconomic
residual  interests claim they satisfy the safe harbor even in situations  where the economics
of the  transfer  clearly  indicate  the  transferee  is  unwilling  or  unable to pay the tax
associated  with  holding  the  interest.  For this  reason,  on  February  7,  2000,  the IRS
published   in  the  Federal   Register   (65  FR  5807)  a  notice  of  proposed   rulemaking
(REG-100276-97;  REG-122450-98)  designed to clarify  the safe  harbor by adding the  "formula
test,"  an  economic  test.  The  proposed   regulation  provides  that  the  safe  harbor  is
unavailable  unless the present  value of the  anticipated  tax  liabilities  associated  with
holding  the  residual  interest  does not  exceed the sum of:  (1) The  present  value of any
consideration  given to the  transferee to acquire the interest;  (2) the present value of the
expected future  distributions  on the interest;  and (3) the present value of the anticipated
tax savings associated with holding the interest as the REMIC generates losses.

        The   notice   of   proposed    rulemaking    also   contained   rules   for   FASITs.
Section 1.860H-6(g)  of the proposed regulations provides  requirements for transfers of FASIT
ownership  interests  and adopts a safe harbor by reference to the safe harbor  provisions  of
the REMIC  regulations.  In January 2001, the IRS published Rev. Proc.  2001-12 (2001-3 I.R.B.
335) to set forth an alternative  safe harbor that  taxpayers  could use while the IRS and the
Treasury considered comments on the proposed  regulations.  Under the alternative safe harbor,
if a transferor meets the  investigation  requirement and the  representation  requirement but
the transfer  fails to meet the formula  test,  the  transferor  may invoke the safe harbor if
the  transferee  meets a two-prong  test (the asset test).  A transferee  generally  meets the
first  prong  of this  test  if,  at the time of the  transfer,  and in each of the two  years
preceding  the year of transfer,  the  transferee's  gross assets  exceed $100 million and its
net assets exceed $10 million.  A transferee  generally meets the second prong of this test if
it is a domestic,  taxable  corporation  and agrees in writing not to transfer the interest to
any  person  other  than  another  domestic,  taxable  corporation  that  also  satisfies  the
requirements  of the asset test. A transferor  cannot rely on the asset test if the transferor
knows, or has reason to know,  that the transferee will not comply with its written  agreement
to limit the restrictions on subsequent transfers of the residual interest.

        Rev. Proc.  2001-12  provides that the asset test fails to be satisfied in the case of
a  transfer  or  assignment  of a  noneconomic  residual  interest  to a foreign  branch of an
otherwise eligible  transferee.  If such a transfer or assignment were permitted,  a corporate
taxpayer  might seek to claim that the  provisions  of an  applicable  income tax treaty would
resource excess  inclusion  income as foreign source income,  and that, as a consequence,  any
U.S. tax  liability  attributable  to the excess  inclusion  income could be offset by foreign
tax credits.  Such a claim would impede the  assessment  or  collection  of U.S. tax on excess
inclusion income,  contrary to the congressional  purpose of assuring that such income will be
taxable in all events. See, e.g., sections 860E(a)(1), (b), (e) and 860G(b) of the Code.

        The Treasury and the IRS have learned that certain taxpayers transferring  noneconomic
residual  interests to foreign  branches have  attempted to rely on the formula test to obtain
safe harbor  treatment  in an effort to impede the  assessment  or  collection  of U.S. tax on
excess inclusion  income.  Accordingly,  the final  regulations  provide that if a noneconomic
residual  interest is  transferred  to a foreign  permanent  establishment  or fixed base of a
U.S.  taxpayer,  the transfer is not eligible for safe harbor treatment under either the asset
test or the formula test.  The final  regulations  also require a transferee to represent that
it will not cause  income  from the  noneconomic  residual  interest to be  attributable  to a
foreign permanent establishment or fixed base.

        Section  1.860E-1(c)(8)  provides  computational  rules  that a  taxpayer  may  use to
qualify for safe harbor  status under the formula  test.  Section  1.860E-1(c)(8)(i)  provides
that  the  transferee  is  presumed  to pay tax at a rate  equal  to the  highest  rate of tax
specified in section  11(b).  Some  commentators  were  concerned  that this  presumed rate of
taxation was too high  because it does not take into  consideration  taxpayers  subject to the
alternative  minimum tax rate.  In light of the comments  received,  this  provision  has been
amended in the final  regulations  to allow  certain  transferees  that compute  their taxable
income  using  the  alternative  minimum  tax  rate to use the  alternative  minimum  tax rate
applicable to corporations.

        Additionally,  Sec.  1.860E-1(c)(8)(iii)  provides  that  the  present  values  in the
formula  test  are to be  computed  using a  discount  rate  equal to the  applicable  Federal
short-term rate prescribed by section 1274(d).  This is a change from the proposed  regulation
and Rev. Proc.  2001-12.  In those publications the provision stated that  "present values are
computed  using a discount  rate equal to the  applicable  Federal rate  prescribed in section
1274(d)  compounded  semiannually"  and  that  "[a]  lower  discount  rate  may be used if the
transferee  can  demonstrate  that  it  regularly  borrows,  in the  course  of its  trade  or
business,  substantial  funds at such lower rate from an unrelated  third  party." The IRS and
the Treasury  Department have learned that,  based on this provision,  certain  taxpayers have
been  attempting  to use  unrealistically  low or zero  interest  rates to satisfy the formula
test,  frustrating the intent of the test.  Furthermore,  the Treasury  Department and the IRS
believe that a rule  allowing  for a rate other than a rate based on an objective  index would
add  unnecessary  complexity  to the  safe  harbor.  As a  result,  the  rule in the  proposed
regulations  that permits a transferee to use a lower  discount  rate, if the  transferee  can
demonstrate that it regularly  borrows  substantial  funds at such lower rate, is not included
in the  final  regulations;  and the  Federal  short-term  rate has been  substituted  for the
applicable  Federal rate. To simplify  taxpayers'  computations,  the final  regulations allow
use of any of the published  short-term  rates,  provided that the present values are computed
with a corresponding  period of compounding.  With the exception of the provisions relating to
transfers to foreign branches,  these changes generally have the proposed  applicability  date
of February 4, 2000,  but  taxpayers  may choose to apply the interest  rate formula set forth
in the proposed  regulation and Rev. Proc.  2001-12 for transfers  occurring  before  November
19, 2002.

        It is  anticipated  that when final  regulations  are adopted  with respect to FASITs,
Sec.  1.860H-6(g) of the proposed  regulations  will be adopted in  substantially  its present
form, with the result that the final  regulations  contained in this document will also govern
transfers of FASIT ownership  interests with  substantially the same  applicability date as is
contained in this document.

Effect on Other Documents

        Rev.  Proc.  2001-12  (2001-3  I.R.B.  335) is obsolete for  transfers of  noneconomic
residual interests in REMICs occurring on or after November 19, 2002.

Special Analyses

        It is hereby  certified that these  regulations  will not have a significant  economic
impact on a substantial  number of small  entities.  This  certification  is based on the fact
that it is unlikely  that a  substantial  number of small  entities  will hold REMIC  residual
interests.  Therefore,  a Regulatory Flexibility Analysis under the Regulatory Flexibility Act
(5 U.S.C.  chapter 6) is not required.  It has been determined that this Treasury  decision is
not a  significant  regulatory  action as defined  in  Executive  Order  12866.  Therefore,  a
regulatory  assessment is not required.  It also has been  determined that sections 553(b) and
553(d)  of the  Administrative  Procedure  Act (5  U.S.C.  chapter  5) do not  apply  to these
regulations.

Drafting Information

        The principal  author of these  regulations  is Courtney  Shepardson.  However,  other
personnel from the IRS and Treasury Department participated in their development.

that:

1.      No purpose of the Seller  relating to the transfer of the Certificate by the Seller to
the Purchaser is or will be to impede the assessment or collection of any tax.

2.      The Seller  understands that the Purchaser has delivered to the Trustee and the Master
Servicer  a  transfer  affidavit  and  agreement  in the  form  attached  to the  Pooling  and
Servicing   Agreement  as  Exhibit  H-1.  The  Seller  does  not  know  or  believe  that  any

Ladies and Gentlemen:

        _________________________    (the    "Purchaser")    intends    to    purchase    from
___________________________   (the  "Seller")  $_____________  Initial  Certificate  Principal
Balance of Home Equity  Mortgage  Asset-Backed  Pass-Through  Certificates,  Series  2005-KS4,
Class [B]  [SB] [R-[__]] (the  "Certificates"),  issued  pursuant to the Pooling and Servicing

shall have the  meanings  set forth in the  Pooling and  Servicing  Agreement.  The  Purchaser
hereby certifies,  represents and warrants to, and covenants with, the Depositor,  the Trustee
and the Master Servicer that:

1.      The  Purchaser  understands  that (a) the  Certificates  have not been and will not be
               registered  or  qualified  under the  Securities  Act of 1933,  as amended (the
               "Act") or any state  securities  law,  (b) the  Depositor is not required to so
               register or qualify the  Certificates,  (c) the Certificates may be resold only
               if registered and qualified  pursuant to the provisions of the Act or any state
               securities law, or if an exemption from such  registration and qualification is
               available,  (d) the  Pooling  and  Servicing  Agreement  contains  restrictions
               regarding the transfer of the Certificates  and (e) the Certificates  will bear
               a legend to the foregoing effect.

2.      The Purchaser is acquiring the  Certificates  for its own account for investment  only
               and not with a view to or for sale in connection with any distribution  thereof
               in any manner that would  violate the Act or any  applicable  state  securities
               laws.

3.      The Purchaser is (a) a substantial,  sophisticated  institutional investor having such
               knowledge  and   experience  in  financial  and  business   matters,   and,  in
               particular,  in such matters related to securities similar to the Certificates,
               such that it is capable of  evaluating  the merits and risks of  investment  in
               the  Certificates,  (b) able to bear the economic  risks of such an  investment
               and (c) an "accredited  investor" within the meaning of Rule 501(a) promulgated
               pursuant to the Act.

4.      The Purchaser has been  furnished  with,  and has had an  opportunity to review (a) [a
               copy of the Private  Placement  Memorandum,  dated  ___________________,  20__,
               relating  to the  Certificates  (b)]  a  copy  of  the  Pooling  and  Servicing
               Agreement and [b] [c] such other information  concerning the Certificates,  the
               Mortgage  Loans and the Depositor as has been  requested by the Purchaser  from
               the  Depositor  or the Seller and is  relevant to the  Purchaser's  decision to
               purchase the  Certificates.  The Purchaser  has had any questions  arising from
               such review answered by the Depositor or the Seller to the  satisfaction of the
               Purchaser.  [If the  Purchaser  did not  purchase  the  Certificates  from  the
               Seller in connection with the initial  distribution of the Certificates and was
               provided with a copy of the Private  Placement  Memorandum  (the  "Memorandum")
               relating to the original sale (the "Original  Sale") of the Certificates by the
               Depositor,  the Purchaser  acknowledges that such Memorandum was provided to it
               by the Seller,  that the  Memorandum  was prepared by the Depositor  solely for
               use in connection  with the Original Sale and the Depositor did not participate
               in or facilitate in any way the purchase of the  Certificates  by the Purchaser
               from the  Seller,  and the  Purchaser  agrees  that it will look  solely to the
               Seller and not to the Depositor  with respect to any damage,  liability,  claim
               or expense  arising out of,  resulting from or in connection  with (a) error or
               omission,  or alleged error or omission,  contained in the  Memorandum,  or (b)
               any   information,   development  or  event  arising  after  the  date  of  the
               Memorandum.]

5.      The  Purchaser  has not and will not nor has it  authorized  or will it authorize  any
               person to (a)  offer,  pledge,  sell,  dispose  of or  otherwise  transfer  any
               Certificate,  any interest in any Certificate or any other similar  security to
               any person in any  manner,  (b) solicit any offer to buy or to accept a pledge,
               disposition  of  other  transfer  of  any  Certificate,  any  interest  in  any
               Certificate  or any other similar  security from any person in any manner,  (c)
               otherwise  approach or negotiate with respect to any Certificate,  any interest
               in any  Certificate  or any  other  similar  security  with any  person  in any
               manner,  (d) make any general  solicitation by means of general  advertising or
               in any  other  manner  or (e) take  any  other  action,  that (as to any of (a)
               through (e) above) would  constitute a distribution  of any  Certificate  under
               the Act, that would render the  disposition  of any  Certificate a violation of
               Section  5 of the  Act or any  state  securities  law,  or that  would  require
               registration or  qualification  pursuant  thereto.  The Purchaser will not sell
               or otherwise  transfer any of the  Certificates,  except in compliance with the
               provisions of the Pooling and Servicing Agreement.

6.      The Purchaser  hereby  certifies,  represents  and warrants to, and covenants with the
               Depositor,  the Trustee and the Master  Servicer that the following  statements
               in (a) or (b) [with respect to Class B - (a), (b), (c) or (d)] are correct:

                             (a)    The  Purchaser  is not an employee  benefit  plan or other
                      plan or arrangement subject to the prohibited  transaction provisions of
                      the  Employee  Retirement  Income  Security  Act  of  1974,  as  amended
                      ("ERISA"),  or Section  4975 of the Internal  Revenue  Code of 1986,  as
                      amended (the  "Code"),  or any person  (including  an insurance  company
                      investing its general account,  an investment manager, a named fiduciary
                      or a trustee  of any such plan) who is using  "plan  assets" of any such
                      plan  to  effect  such  acquisition  (each  of the  foregoing,  a  "Plan

                             (b)    the  Purchaser  has provided the  Trustee,  the  Depositor
                      and the Master Servicer with an Opinion of Counsel  acceptable to and in
                      form and substance  satisfactory  to the Trustee,  the Depositor and the
                      Master   Servicer  to  the  effect  that  the  purchase  or  holding  of
                      Certificates  is permissible  under  applicable law, will not constitute
                      or result in any non-exempt prohibited  transaction under Section 406 of
                      ERISA  or  Section 4975  of the Code (or  comparable  provisions  of any
                      subsequent enactments),  and will not subject the Trustee, the Depositor

                                       LIMITED GUARANTY



                                         ARTICLE XII

                   Subordinate Certificate Loss Coverage; Limited Guaranty

        Section 12.01.  Subordinate  Certificate Loss Coverage;  Limited Guaranty. (a) Subject
to  subsection  (c)  below,  prior  to the  later  of the  third  Business  Day  prior to each
Distribution  Date or the related  Determination  Date, the Master  Servicer  shall  determine
whether it or any Subservicer will be entitled to any  reimbursement  pursuant to Section 3.10
on such  Distribution Date for Advances or Subservicer  Advances  previously made, (which will
not be Advances or  Subservicer  Advances that were made with respect to  delinquencies  which
were subsequently  determined to be Excess Special Hazard Losses,  Excess Fraud Losses, Excess
Bankruptcy  Losses or  Extraordinary  Losses)  and, if so, the Master  Servicer  shall  demand
payment  from  Residential  Funding  of an  amount  equal to the  amount  of any  Advances  or
Subservicer  Advances  reimbursed  pursuant to Section  3.10,  to the extent such  Advances or
Subservicer  Advances  have  not been  included  in the  amount  of the  Realized  Loss in the
related  Mortgage Loan, and shall  distribute the same to the Class SB  Certificateholders  in
the same manner as if such amount were to be distributed pursuant to Section 4.02.

               (b)    Subject  to  subsection  (c)  below,  prior to the  later  of the  third
Business Day prior to each  Distribution  Date or the related  Determination  Date, the Master
Servicer  shall  determine  whether any  Realized  Losses  (other than Excess  Special  Hazard
Losses,  Excess  Bankruptcy  Losses,  Excess  Fraud Losses and  Extraordinary  Losses) will be
allocated to the Class SB  Certificates  on such  Distribution  Date pursuant to Section 4.05,
and, if so, the Master  Servicer shall demand payment from  Residential  Funding of the amount
of such  Realized Loss and shall  distribute  the same to the Class SB  Certificateholders  in
the same manner as if such amount were to be distributed  pursuant to Section 4.02;  provided,
however,  that the  amount of such  demand in  respect  of any  Distribution  Date shall in no
event be greater than the sum of (i) the  additional  amount of Accrued  Certificate  Interest
that would have been paid for the Class SB  Certificateholders  on such  Distribution Date had
such  Realized  Loss or Losses  not  occurred  plus (ii) the  amount of the  reduction  in the
Certificate  Principal Balances of the Class SB  Certificates on such Distribution Date due to
such Realized Loss or Losses.  Notwithstanding  such  payment,  such Realized  Losses shall be
deemed to have been borne by the  Certificateholders  for  purposes  of Section  4.05.  Excess
Special  Hazard  Losses,  Excess Fraud  Losses,  Excess  Bankruptcy  Losses and  Extraordinary
Losses  allocated  to the  Class SB  Certificates  will  not  be  covered  by the  Subordinate
Certificate Loss Obligation.

               (c)    Demands for  payments  pursuant to this  Section  shall be made prior to
the  later  of the  third  Business  Day  prior  to  each  Distribution  Date  or the  related
Determination  Date by the Master  Servicer with written  notice  thereof to the Trustee.  The
maximum amount that  Residential  Funding shall be required to pay pursuant to this Section on
any Distribution  Date (the "Amount  Available")  shall be equal to the lesser of (X) ________
minus the sum of (i) all  previous  payments  made  under  subsections  (a) and (b) hereof and
(ii) all draws under the Limited  Guaranty  made in lieu of such  payments as described  below
in  subsection  (d)  and  (Y) the  then  outstanding  Certificate  Principal  Balances  of the
Class SB  Certificates,  or such lower amount as may be established pursuant to Section 12.02.
Residential  Funding's  obligations as described in this Section are referred to herein as the
"Subordinate Certificate Loss Obligation."

               (d)    The Trustee will promptly notify General Motors  Acceptance  Corporation
of any  failure  of  Residential  Funding  to make any  payments  hereunder  and shall  demand
payment  pursuant  to the  limited  guaranty  (the  "Limited  Guaranty"),  executed by General
Motors Acceptance  Corporation,  of Residential Funding's obligation to make payments pursuant
to this  Section,  in an amount equal to the lesser of (i) the Amount  Available and (ii) such
required  payments,  by delivering to General Motors  Acceptance  Corporation a written demand
for  payment  by  wire  transfer,  not  later  than  the  second  Business  Day  prior  to the
Distribution Date for such month, with a copy to the Master Servicer.

               (e)    All payments  made by  Residential  Funding  pursuant to this Section or
amounts  paid under the  Limited  Guaranty  shall be  deposited  directly  in the  Certificate
Account,   for  distribution  on  the  Distribution  Date  for  such  month  to  the  Class SB
Certificateholders.

               (f)    The  Depositor  shall  have  the  option,  in its  sole  discretion,  to
substitute  for either or both of the Limited  Guaranty or the  Subordinate  Certificate  Loss
Obligation  another instrument in the form of a corporate  guaranty,  an irrevocable letter of
credit,  a surety bond,  insurance  policy or similar  instrument or a reserve fund;  provided
that (i) the  Depositor  obtains  (subject  to the  provisions  of Section  10.01(f) as if the
Depositor was  substituted  for the Master Servicer solely for the purposes of such provision)
an Opinion of Counsel  (which  need not be an opinion of  independent  counsel)  to the effect
that  obtaining such  substitute  corporate  guaranty,  irrevocable  letter of credit,  surety
bond,  insurance  policy or similar  instrument  or reserve fund will not cause either (a) any
federal tax to be imposed on the Trust Fund,  including  without  limitation,  any federal tax
imposed  on  "prohibited   transactions"  under  Section   860(F)(a)(1)  of  the  Code  or  on
"contributions  after the startup  date"  under  Section  860(G)(d)(1)  of the Code or (b) the
Trust  Fund to fail to  qualify as a REMIC at any time that any  Certificate  is  outstanding,
and (ii) no such  substitution  shall be made unless (A) the  substitute  Limited  Guaranty or
Subordinate  Certificate  Loss  Obligation  is for an  initial  amount  not less than the then
current  Amount  Available  and  contains   provisions  that  are  in  all  material  respects
equivalent  to the  original  Limited  Guaranty or  Subordinate  Certificate  Loss  Obligation
(including that no portion of the fees,  reimbursements  or other  obligations  under any such
instrument  will be borne by the  Trust  Fund),  (B) the long  term  debt  obligations  of any
obligor of any substitute  Limited  Guaranty or Subordinate  Certificate  Loss  Obligation (if
not  supported by the Limited  Guaranty)  shall be rated at least the lesser of (a) the rating
of the long term debt obligations of General Motors  Acceptance  Corporation as of the date of
issuance  of the  Limited  Guaranty  and (b) the rating of the long term debt  obligations  of
General Motors  Acceptance  Corporation at the date of such  substitution and (C) if the Class
SB Certificates have been rated, the Depositor  obtains written  confirmation from each Rating
Agency  that  rated the  Class SB  Certificates  at the  request  of the  Depositor  that such
substitution  shall not lower the rating on the Class SB  Certificates below the lesser of (a)
the  then-current  rating assigned to the Class SB  Certificates by such Rating Agency and (b)
the  original  rating  assigned  to the  Class SB  Certificates  by such  Rating  Agency.  Any
replacement of the Limited  Guaranty or Subordinate  Certificate  Loss Obligation  pursuant to
this  Section  shall  be  accompanied  by a  written  Opinion  of  Counsel  to the  substitute
guarantor or obligor,  addressed to the Master Servicer and the Trustee,  that such substitute
instrument  constitutes a legal, valid and binding  obligation of the substitute  guarantor or
obligor,  enforceable in accordance  with its terms,  and concerning such other matters as the
Master Servicer and the Trustee shall reasonably  request.  Neither the Depositor,  the Master
Servicer  nor the  Trustee  shall be  obligated  to  substitute  for or  replace  the  Limited
Guaranty or Subordinate Certificate Loss Obligation under any circumstance.

               Section 12.02.  Amendments  Relating to the Limited  Guaranty.  Notwithstanding
Sections  11.01 or 12.01:  (i) the  provisions of this Article XII may be amended,  superseded
or deleted,  (ii) the Limited  Guaranty or  Subordinate  Certificate  Loss  Obligation  may be
amended,  reduced  or  canceled,  and (iii) any other  provision  of this  Agreement  which is
related or  incidental  to the  matters  described  in this  Article XII may be amended in any
manner;  in each case by written  instrument  executed or  consented to by the  Depositor  and
Residential Funding but without the consent of any  Certificateholder  and without the consent
of the Master  Servicer or the Trustee being required  unless any such amendment  would impose
any  additional  obligation  on, or otherwise  adversely  affect the  interests of, the Master
Servicer or the  Trustee,  as  applicable;  provided  that the  Depositor  shall also obtain a
letter from each  Rating  Agency that rated the  Class SB  Certificates  at the request of the
Depositor to the effect that such  amendment,  reduction,  deletion or  cancellation  will not
lower the  rating  on the  Class SB  Certificates  below  the  lesser of (a) the  then-current
rating  assigned  to the  Class SB  Certificates  by such Rating  Agency and (b) the  original
rating assigned to the Class SB  Certificates by such Rating Agency,  unless (A) the Holder of
100% of the Class SB  Certificates  is  Residential  Funding or an  Affiliate  of  Residential
Funding,  or (B) such  amendment,  reduction,  deletion or  cancellation is made in accordance
with Section  11.01(e)  and,  provided  further  that the  Depositor  obtains  (subject to the
provisions of Section  10.01(f) as if the Depositor was  substituted  for the Master  Servicer
solely  for  the  purposes  of  such  provision),  in the  case  of a  material  amendment  or
supersession  (but not a reduction,  cancellation  or deletion of the Limited  Guaranty or the
Subordinate  Certificate  Loss  Obligation),  an  Opinion  of  Counsel  (which  need not be an
opinion of  independent  counsel) to the effect that any such amendment or  supersession  will
not cause  either  (a) any  federal  tax to be imposed on the Trust  Fund,  including  without
limitation,  any federal tax imposed on "prohibited  transactions" under Section 860F(a)(1) of
the Code or on  "contributions  after the startup date" under  Section  860G(d)(1) of the Code
or (b) the  Trust  Fund to fail to  qualify  as a REMIC at any time  that any  Certificate  is
outstanding.  A copy of any such  instrument  shall be  provided to the Trustee and the Master
Servicer  together with an Opinion of Counsel that such  amendment  complies with this Section
12.02.

thereto,  dated  as of  ________,  with  respect  to the  Home  Equity  Mortgage  Asset-Backed
Pass-Through Certificates, Series 2005-KS4 (the "Certificates"); and

               WHEREAS,  pursuant to Section  12.01 of the  Servicing  Agreement,  Residential
Funding  agrees to make payments to the Holders of the Class SB  Certificates  with respect to
certain losses on the Mortgage Loans as described in the Servicing Agreement; and

               WHEREAS,  GMAC  desires  to  provide  certain  assurances  with  respect to the
ability of  Residential  Funding to secure  sufficient  funds and  faithfully  to perform  its
Subordinate Certificate Loss Obligation;

               NOW THEREFORE,  in  consideration  of the premises herein contained and certain

2.      Provision  of Funds.  (a) GMAC agrees to  contribute  and  deposit in the  Certificate
Account on behalf of Residential  Funding (or otherwise provide to Residential  Funding, or to
cause to be made available to Residential  Funding),  either directly or through a subsidiary,
in any case  prior to the  related  Distribution  Date,  such  moneys  as may be  required  by
Residential  Funding to perform its  Subordinate  Certificate  Loss Obligation when and as the
same  arises  from time to time upon the demand of the  Trustee  in  accordance  with  Section
12.01 of the Servicing Agreement.

               (b)    The agreement  set forth in the preceding  clause (a) shall be absolute,
irrevocable and  unconditional  and shall not be affected by the transfer by GMAC or any other
person  of  all  or any  part  of  its  or  their  interest  in  Residential  Funding,  by any
insolvency,  bankruptcy,  dissolution or other proceeding affecting Residential Funding or any
other person,  by any defense or right of  counterclaim,  set-off or recoupment  that GMAC may
have against  Residential  Funding or any other  person or by any other fact or  circumstance.
Notwithstanding  the foregoing,  GMAC's  obligations under clause (a) shall terminate upon the
earlier of  (x) substitution  for this Limited  Guaranty  pursuant to Section  12.01(f) of the
Servicing  Agreement,  or (y) the  termination  of the Trust Fund  pursuant  to the  Servicing
Agreement.

3.      Waiver.  GMAC hereby waives any failure or delay on the part of  Residential  Funding,
the Trustee or any other person in  asserting or enforcing  any rights or in making any claims
or  demands  hereunder.  Any  defective  or  partial  exercise  of any such  rights  shall not
preclude any other or further  exercise of that or any other such right.  GMAC further  waives
demand,  presentment,  notice of default,  protest, notice of acceptance and any other notices
with respect to this  Limited  Guaranty,  including,  without  limitation,  those of action or
non-action on the part of Residential Funding or the Trustee.

4.      Modification,  Amendment  and  Termination.  This  Limited  Guaranty  may be modified,
amended or terminated  only by the written  agreement of GMAC and the Trustee and only if such
modification,  amendment or  termination  is permitted  under  Section  12.02 of the Servicing
Agreement.  The  obligations of GMAC under this Limited  Guaranty shall continue and remain in
effect so long as the  Servicing  Agreement  is not  modified or amended in any way that might
affect the obligations of GMAC under this Limited  Guaranty  without the prior written consent
of GMAC.

5.      Successor.  Except as otherwise  expressly  provided herein,  the guarantee herein set
forth shall be binding upon GMAC and its respective successors.

6.      Governing  Law.  This Limited  Guaranty  shall be governed by the laws of the State of
New York.

7.      Authorization  and Reliance.  GMAC  understands  that a copy of this Limited  Guaranty

the Servicing  Agreement and GMAC hereby  authorizes  the Depositor and the Trustee to rely on
the covenants and agreements set forth herein.

8.      Definitions.  Capitalized  terms used but not otherwise  defined herein shall have the
meaning given them in the Servicing Agreement.

9.      Counterparts.  This Limited  Guaranty  may be executed in any number of  counterparts,
each of which shall be deemed to be an original and such  counterparts  shall  constitute  but
one and the same instrument.







               IN WITNESS  WHEREOF,  GMAC has caused this Limited  Guaranty to be executed and
delivered by its respective  officers  thereunto duly  authorized as of the day and year first

violation  of Section 5 of the 1933 Act or require  registration  pursuant  thereto,  and that
the Seller has not  offered  the Rule 144A  Securities  to any person  other than the Buyer or
another "qualified institutional buyer" as defined in Rule 144A under the 1933 Act.

        a transfer,  pledge or other disposition of the Rule 144A Securities,  any interest in
        the Rule 144A Securities or any other similar  security from, or otherwise  approached

        Securities or any other similar  security with, any person in any manner,  or made any
        general  solicitation by means of general advertising or in any other manner, or taken
        any other action,  that would  constitute a distribution  of the Rule 144A  Securities

changes in the  information and conclusions  herein.  Until such notice is given,  the Buyer's
