PRELIMINARY STATEMENT:

The Depositor intends to sell pass-through certificates (collectively, the “Certificates”), to be issued hereunder in multiple classes, which in the aggregate shall evidence the entire beneficial ownership interest in each REMIC (as defined herein) created hereunder. The Trust Fund shall consist of a segregated pool of assets consisting of the Mortgage Loans and certain other related assets subject to this Agreement.

REMIC I

As provided herein, the Trustee shall elect to treat the segregated pool of assets consisting of the Mortgage Loans and certain other related assets (other than any Master Servicer Prepayment Charge Payment Amounts, the Net WAC Rate Carryover Reserve Account, the Swap Account and the Interest Rate Swap Agreement) subject to this Agreement as a REMIC for federal income tax purposes, and such segregated pool of assets shall be designated as “REMIC I.” The Class R-I Interest shall be the sole class of “residual interests” in REMIC I for purposes of the REMIC Provisions (as defined herein). The following table irrevocably sets forth the designation, the REMIC I Remittance Rate, the initial Uncertificated Balance and, for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” for each of the REMIC I Regular Interests (as defined herein). None of the REMIC I Regular Interests shall be certificated.

(b)        In addition to the specific rights of the NIMS Insurer and the Guarantor identified in this Agreement but subject to the provisions of Section 8.01(iii) and Section 8.02(a)(v), the NIMS Insurer or the Guarantor (as provided in Section 1.03(c)) shall have the right to direct the Trustee relating to the exercise of any remedy available to the Trustee or the exercise of any power conferred on the Trustee pursuant to this Agreement. Notwithstanding anything to the contrary anywhere in this Agreement, all rights of the Guarantor hereunder, except any rights to indemnification, shall permanently terminate upon the later to occur of (A) such time as the Guaranteed Certificates shall no longer be outstanding and (B) the payment in full to the Guarantor of any amounts owed to the Guarantor in respect of its guarantee of payment on the Guaranteed Certificates; provided that the Guarantor shall not have any rights hereunder, except indemnification rights, so long as any default has occurred and is continuing under the Guaranty.

(c)        The rights of the NIMS Insurer or the Guarantor referenced in Sections 1.03(b), 3.02, 6.04, 6.06(a), 6.07, 7.01, 7.02(a), 7.04, 8.07 and 8.10 of this Agreement shall be applied as follows:

SECTION 2.01. Conveyance of Mortgage Loans.

The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, assign, set over and otherwise convey to the Trustee without recourse for the benefit of the Certificateholders all the right, title and interest of the Depositor, including any security interest therein for the benefit of the Depositor, in and to the Mortgage Loans identified on the Mortgage Loan Schedule, the rights of the Depositor under the Mortgage Loan Purchase Agreement, all other assets included or to be included in REMIC I, payments made to the Trustee by the Swap Administrator under the Swap Administration Agreement and the Swap Account. Such assignment includes all interest and principal received by the Depositor or the Master Servicer on or with respect to the Mortgage Loans (other than payments of principal and interest due on such Mortgage Loans on or before the Cut-off Date). The Depositor herewith delivers to the Trustee an executed copy of the Mortgage Loan Purchase Agreement and the Pool Policy and the Trustee, on behalf of the Certificateholders, acknowledges receipt of the same.

In connection with such transfer and assignment, the Depositor does hereby deliver to, and deposit with the Trustee the following documents or instruments with respect to each Mortgage Loan so transferred and assigned, and the Depositor shall deliver or cause to be delivered to the Custodian, the following documents or instruments (a “Mortgage File”):

(i)         the original Mortgage Note, endorsed in blank, without recourse, or in the following form: “Pay to the order of Deutsche Bank National Trust Company, as Trustee under the applicable agreement, without recourse,” with all prior and intervening endorsements showing a complete chain of endorsement from the originator to the Person so endorsing to the Trustee, or with respect to any lost Mortgage Note, an original Lost Note Affidavit; provided however, that such substitutions of Lost Note Affidavits for original Mortgage Notes may occur only with respect to Mortgage Loans, the aggregate Cut-off Date Principal Balance of which is less than or equal to 2.00% of the Pool Balance as of the Cut-off Date;

(ii)         the original Mortgage, with evidence of recording thereon, and a copy, certified by the appropriate recording office, of the recorded power of attorney, if the Mortgage was executed pursuant to a power of attorney, with evidence of recording thereon;

(iii) an original Assignment assigned in blank, without recourse;

(iv)        the original recorded intervening Assignment or Assignments showing a complete chain of assignment from the originator to the Person assigning the Mortgage to the Trustee as contemplated by the immediately preceding clause (iii) or the original unrecorded intervening Assignments;

(v)        the original or copies of each assumption, modification, written assurance or substitution agreement, if any; and

(vi)        the original lender’s title insurance policy or an attorney’s opinion of title or similar guarantee of title acceptable to mortgage lenders generally in the jurisdiction where the Mortgaged Property is located, together with all endorsements or riders which were issued with or subsequent to the issuance of such policy, or in the event such original title policy is unavailable, a written commitment or uniform binder or preliminary report of title issued by the title insurance or escrow company.

If any of the documents referred to in Sections 2.01(ii), (iii) or (iv) above has as of the Closing Date been submitted for recording but either (x) has not been returned from the applicable public recording office or (y) has been lost or such public recording office has retained the original of such document, the obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon (1) delivery to the Trustee, or to the appropriate Custodian on behalf of the Trustee, of a copy of each such document certified by the Originator in the case of (x) above or the applicable public recording office in the case of (y) above to be a true and complete copy of the original that was submitted for recording and (2) if such copy is certified by the Originator, delivery to the Trustee, or to the appropriate Custodian on behalf of the Trustee, promptly upon receipt thereof of either the original or a copy of such document certified by the applicable public recording office to be a true and complete copy of the original. If the original lender’s title insurance policy was not delivered pursuant to Section 2.01(vi) above, the Depositor shall deliver or cause to be delivered to the Trustee, or to the appropriate Custodian on behalf of the Trustee, promptly after receipt thereof, the original lender’s title insurance policy. The Depositor shall deliver or cause to be delivered to the Trustee, or to the appropriate Custodian on behalf of the Trustee, promptly upon receipt thereof any other original documents constituting a part of a Mortgage File received with respect to any Mortgage Loan, including, but not limited to, any original documents evidencing an assumption or modification of any Mortgage Loan.

The Master Servicer (in its capacity as Seller) shall promptly (and in no event later than thirty (30) Business Days, subject to extension upon a mutual agreement between the Seller and the Trustee, following the later of (i) the Closing Date, (ii) the date on which the Seller receives the Assignment from the Custodian and (iii) the date of receipt by the Master Servicer of the recording information for a Mortgage) submit or cause to be submitted for recording, at no expense to the Trust Fund or the Trustee, in the appropriate public office for real property records, each Assignment referred to in Sections 2.01(iii) and (iv) above and shall execute each original Assignment referred to in Section 2.01(iii) above in the following form: “Deutsche Bank National Trust Company, as Trustee under the applicable agreement.” In the event that any such Assignment is lost or returned unrecorded because of a defect therein, the Master Servicer (in its capacity as Seller) shall promptly prepare or cause to be prepared a substitute Assignment or cure or cause to be cured such defect, as the case may be, and thereafter cause each such Assignment to be duly recorded.

Notwithstanding the foregoing, however, for administrative convenience and facilitation of servicing and to reduce closing costs, so long as recordation of an Assignment is not necessary to protect the Trustee’s and the Certificateholders’ interests in the related

Mortgage Loan under the laws of the jurisdiction in which the related Mortgaged Property is located, as evidenced by an Opinion of Counsel reasonable satisfactory to the Guarantor, the Assignments shall not be required to be submitted for recording (except with respect to any Mortgage Loan located in Maryland) unless such failure to record would result in a withdrawal or a downgrading by any Rating Agency of the rating on any Class of Certificates; provided further, however, each Assignment shall be submitted for recording by the Seller in the manner described above, at no expense to the Trust Fund or the Trustee, upon the earliest to occur of: (i) reasonable direction by Holders of Certificates entitled to at least 25% of the Voting Rights, the Guarantor or the NIMS Insurer, (ii) failure of the Master Servicer Termination Test, (iii) the occurrence of a bankruptcy or insolvency relating to the Seller, (iv) the occurrence of a servicing transfer as described in Section 7.02 hereof and (v) if the Seller is not the Master Servicer and with respect to any one Assignment or Mortgage, the occurrence of a bankruptcy, insolvency or foreclosure relating to the Mortgagor under the related Mortgage. Notwithstanding the foregoing, if the Master Servicer is unable to pay the cost of recording the Assignments, such expense shall be paid by the Trustee and shall be reimbursable to the Trustee as an Extraordinary Trust Fund Expense.

All original documents relating to the Mortgage Loans that are not delivered to the Trustee, or to the appropriate Custodian on behalf of the Trustee, are and shall be held by or on behalf of the Seller, the Depositor or the Master Servicer, as the case may be, in trust for the benefit of the Trustee on behalf of the Certificateholders. In the event that any such original document is required pursuant to the terms of this Section to be a part of a Mortgage File, such document shall be delivered promptly to the Trustee, or to the appropriate Custodian on behalf of the Trustee. Any such original document delivered to or held by the Depositor that is not required pursuant to the terms of this Section to be a part of a Mortgage File, shall be delivered promptly to the Master Servicer.

The parties hereto understand and agree that it is not intended that any mortgage loan be included in the Trust that is a “High-Cost Home Loan” as defined by HOEPA or any other applicable predatory or abusive lending laws.

SECTION 2.02. Acceptance of REMIC I by the Trustee.

Subject to the provisions of Section 2.01 and subject to any exceptions noted on the exception report described in the next paragraph below, the Trustee acknowledges receipt (or, with respect to Mortgage Loans subject to a Custodial Agreement, receipt by the respective Custodian as the duly appointed agent of the Trustee) of the documents referred to in Section 2.01 (other than such documents described in Section 2.01(v)) above and all interests and all other assets included in the definition of “REMIC I” under clauses (i), (iii), (iv) and (v) (to the extent of amounts deposited into the Distribution Account) and declares that it, or such Custodian as its agent, holds and shall hold such documents and the other documents delivered to it constituting a Mortgage File, and that it holds or shall hold all such assets and such other assets included in the definition of “REMIC I” in trust for the exclusive use and benefit of all present and future Certificateholders.

On or prior to the Closing Date, the Trustee agrees, for the benefit of the Certificateholders, to execute and deliver (or cause the Custodian to execute and deliver) to the

Depositor, the Guarantor and the NIMS Insurer an acknowledgment of receipt of the Mortgage Note (with any exceptions noted), substantially in the form attached as Exhibit C-3 hereto.

The Trustee agrees, for the benefit of the Certificateholders, to review (or cause a Custodian on its behalf to review) each Mortgage Note within 45 days of the Closing Date and to certify in substantially the form attached hereto as Exhibit C-1 (or cause the Custodian to certify in the form of the Initial Certification attached to the Custodial Agreement) to the Depositor, the Master Servicer, the Guarantor and the NIMS Insurer, if any, that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan specifically identified in the exception report annexed thereto as not being covered by such certification), (i) all documents constituting part of such Mortgage File (other than such documents described in Section 2.01(v)) required to be delivered to it pursuant to this Agreement are in its possession, (ii) such documents have been reviewed by it or such Custodian and are not mutilated, torn or defaced unless initialed by the related borrower and relate to such Mortgage Loan, (iii) based on its or the Custodian’s examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule that corresponds to items (1) through (3), (6), (9), (10), (13), (15) and (19) of the definition of “Mortgage Loan Schedule” accurately reflects information set forth in the Mortgage File. It is herein acknowledged that, in conducting such review, the Trustee or such Custodian was under no duty or obligation (i) to inspect, review or examine any such documents, instruments, certificates or other papers to determine whether they are genuine, enforceable, or appropriate for the represented purpose or whether they have actually been recorded or that they are other than what they purport to be on their face or (ii) to determine whether any Mortgage File should include any of the documents specified in clause (v) of Section 2.01.

Prior to the first anniversary date of this Agreement the Trustee shall deliver (or cause the Custodian to deliver) to the Depositor, the Master Servicer, the Guarantor and the NIMS Insurer a final certification in the form annexed hereto as Exhibit C-2 (or shall cause the Custodian to deliver to the Trustee, the Depositor, the Master Servicer, the Guarantor and the NIMS Insurer a final certification in the form attached to the Custodial Agreement) evidencing the completeness of the Mortgage Files, with any applicable exceptions noted thereon, with respect to all of the Mortgage Loans. Upon the request of the Master Servicer or the Guarantor, any exception report related to the final certification shall be provided in an electronic computer readable format as mutually agreed upon by the Master Servicer and the Trustee (or the Custodian on behalf of the Trustee).

If in the process of reviewing the Mortgage Files and making or preparing, as the case may be, the certifications referred to above, the Trustee or any Custodian finds any document or documents constituting a part of a Mortgage File to be missing, mutilated, torn or defaced or does not conform to the requirements identified above, at the conclusion of its review the Trustee (or the Custodian on behalf of the Trustee) shall so notify the Depositor, the Guarantor, the NIMS Insurer and the Master Servicer. In addition, upon the discovery by the Depositor, the Guarantor, the NIMS Insurer, the Master Servicer or the Trustee of a breach of any of the representations and warranties made by the Seller in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which materially adversely affects such Mortgage Loan or the interests of the related Certificateholders in such Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties.

The Trustee (or the Custodian on behalf of the Trustee) shall, at the written request and expense of any Certificateholder, Certificate Owner or the Guarantor, provide a written report to such Certificateholder, Certificate Owner or the Guarantor, of all Mortgage Files released to the Master Servicer for servicing purposes.

SECTION 2.03. Repurchase or Substitution of Mortgage Loans by the Seller or the Depositor; Payment of Prepayment Charge Payment Amounts.

(a)        Upon discovery or receipt of notice (including notice under Section 2.02) of any materially defective document in, or that a document is missing from, the Mortgage File or of the breach by the Seller of any representation, warranty or covenant under the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which materially adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, the Trustee shall promptly notify the Seller, the NIMS Insurer, the Guarantor and the Master Servicer of such defect, missing document or breach and request that the Seller deliver such missing document or cure such defect or breach within 90 days from the date the Seller had knowledge or was notified of such missing document, defect or breach, and if the Seller does not deliver such missing document or cure such defect or breach in all material respects during such period, the Master Servicer (or, in accordance with Section 6.06(b), the Trustee) shall enforce the obligations of the Seller under the Mortgage Loan Purchase Agreement to repurchase such Mortgage Loan from REMIC I at the Purchase Price within 90 days after the date on which the Seller was notified (subject to Section 2.03(d)) of such missing document, defect or breach, if and to the extent that the Seller is obligated to do so under the Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased Mortgage Loan shall be deposited in the Collection Account, and the Trustee, upon receipt of written certification from the Master Servicer of such deposit, shall (or cause the Custodian to) release to the Seller the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Seller shall furnish to it and as shall be necessary to vest in the Seller any Mortgage Loan released pursuant hereto, and the Trustee shall not have any further responsibility with regard to such Mortgage File. In lieu of repurchasing any such Mortgage Loan as provided above, if so provided in the Mortgage Loan Purchase Agreement, the Seller may cause such Mortgage Loan to be removed from REMIC I (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(c). It is understood and agreed that the obligation of the Seller to cure or to repurchase (or to substitute for) any Mortgage Loan as to which a document is missing, a material defect in a document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy respecting such omission, defect or breach available to the Trustee on behalf of the Certificateholders. Notwithstanding the foregoing, if either the Seller or the Depositor is liable for a breach under this Section 2.03, it shall promptly reimburse the Guarantor for all expenses incurred by the Guarantor in respect of enforcing the remedies for such breach.

(b)        (i) Promptly upon the earlier of discovery by the Master Servicer or receipt of notice by the Master Servicer of the breach of any representation, warranty or covenant of the Master Servicer set forth in Section 2.05, which materially and adversely affects the

interests of the Certificateholders in any Mortgage Loan, the Master Servicer shall cure such breach in all material respects.

(ii) Notwithstanding the provisions of Section 2.03(b)(i) above,

(A)       on the later of (x) the Master Servicer Remittance Date next following the earlier of discovery by the Master Servicer or receipt of notice by the Master Servicer of the breach of the representation made by the Master Servicer in Section 2.05(vii), which breach materially and adversely affects the interests of the Holders of the Class P Certificates to any Prepayment Charge and (y) the Master Servicer Remittance Date next following the Prepayment Period relating to such a breach, the Master Servicer shall deposit into the Collection Account the amount of the scheduled Prepayment Charge, less any amount collected and deposited by the Master Servicer into the Collection Account in respect of such Prepayment Charge; and

(B)        on the later of (x) the Master Servicer Remittance Date next following the earlier of discovery by the Master Servicer or receipt of notice by the Master Servicer of the breach of the covenant made by the Master Servicer in Section 2.05(viii), which breach materially and adversely affects the interests of the Holders of the Class P Certificates to any Prepayment Charge and (y) the Master Servicer Remittance Date next following the Prepayment Period relating to such a breach, the Master Servicer shall deposit into the Collection Account, as a Master Servicer Prepayment Charge Payment Amount, the amount of the waived Prepayment Charge, but only to the extent required under Section 2.03(b)(iii) below.

(iii) If with respect to any Prepayment Period,

(A)       the dollar amount of Prepayment Charges that are the subject of breaches by the Master Servicer of the covenant made by the Master Servicer in Section 2.05(viii), which breaches materially and adversely affect the interests of the Holders of the Class P Certificates to such Prepayment Charges, exceeds

(B)        5% of the total dollar amount of Prepayment Charges payable by Mortgagors in connection with Principal Prepayments on the related Mortgage Loans that occurred during such Prepayment Period,

then the amount required to be paid by the Master Servicer pursuant to Section 2.03(b)(ii)(B) above shall be limited to an amount, that when added to the amount of Prepayment Charges actually collected by the Master Servicer in respect of Prepayment Charges relating to Principal Prepayments on the related Mortgage Loans that occurred during such Prepayment Period, shall yield a sum equal to 95% of the total dollar amount of Prepayment Charges (exclusive of (A) Prepayment Charges not enforced or collected upon because (i) the enforceability thereof shall have been limited by bankruptcy, insolvency, moratorium, receivership and other similar laws relating to creditors’ rights generally or (ii) the collectability thereof shall have been limited due to acceleration in connection with a foreclosure or other involuntary payment and (B) Prepayment Charges waived by the Master Servicer when such waiver does not breach the covenant set forth in Section 2.05(viii)) payable by Mortgagors in connection with Principal Prepayments on the related Mortgage Loans that occurred during such Prepayment Period.

(c)        Any substitution of Qualified Substitute Mortgage Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a), in the case of the Seller, or Section 2.03(b), in the case of the Depositor, must be effected prior to the date which is two years after the Startup Day for REMIC I.

As to any Deleted Mortgage Loan for which the Seller or the Depositor substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution shall be effected by the Seller or the Depositor, as the case may be, delivering to the Trustee (or the Custodian on behalf of the Trustee), for such Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2.01, together with an Officers’ Certificate providing that each such Qualified Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Shortfall Amount (as described below), if any, in connection with such substitution. The Trustee (or the Custodian on behalf of the Trustee) shall acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans and, within ten Business Days thereafter, review such documents as specified in Section 2.02 and deliver to the Depositor, the Guarantor, the NIMS Insurer, the Trustee and the Master Servicer, with respect to such Qualified Substitute Mortgage Loan or Loans, a certification substantially in the form attached hereto as Exhibit C-1, with any applicable exceptions noted thereon. Within one year of the date of substitution, the Trustee (or the Custodian on behalf of the Trustee) shall deliver to the Depositor, the Guarantor, the NIMS Insurer and the Master Servicer a certification substantially in the form of Exhibit C-2 hereto with respect to such Qualified Substitute Mortgage Loan or Loans, with any applicable exceptions noted thereon. Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution are not part of REMIC I and shall be retained by the Depositor or the Seller, as the case may be. For the month of substitution, distributions to Certificateholders shall reflect the Monthly Payment due on such Deleted Mortgage Loan on or before the Due Date in the month of substitution, and the Depositor or the Seller, as the case may be, shall thereafter be entitled to retain all amounts subsequently received in respect of such Deleted Mortgage Loan. The Depositor shall give or cause to be given written notice to the Certificateholders, the Guarantor, the NIMS Insurer that such substitution has taken place, shall amend the Mortgage Loan Schedule and, if applicable, the Prepayment Charge Schedule, to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan Schedule to the Trustee, the Guarantor and the NIMS Insurer. Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall constitute part of the Mortgage Pool and shall be subject in all respects to the terms of this Agreement and, in the case of a substitution effected by the Seller, the Mortgage Loan Purchase Agreement, including all applicable representations and warranties thereof.

For any month in which the Depositor or the Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer shall determine the amount (the “Substitution Shortfall Amount”), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan, the Scheduled Principal Balance thereof as of the date of substitution, together with one month’s interest on such Scheduled Principal Balance at the applicable Net Mortgage Rate. On the date of such substitution, the Depositor or the Seller, as the case may be, shall deliver or cause to be delivered to the Master Servicer for deposit in the

Collection Account an amount equal to the Substitution Shortfall Amount, if any, and the Trustee, upon receipt of the related Qualified Substitute Mortgage Loan or Loans and certification by the Master Servicer of such deposit, shall (or cause the Custodian to) release to the Depositor or the Seller, as the case may be, the related Mortgage File or Files and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Depositor or the Seller, as the case may be, shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto.

In addition, the Depositor or the Seller, as the case may be, shall obtain at its own expense and deliver to the Trustee, the NIMS Insurer and the Guarantor an Opinion of Counsel to the effect that such substitution shall not cause (a) any federal tax to be imposed on any Trust REMIC, 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 Trust REMIC to fail to qualify as a REMIC at any time that any Certificate is outstanding.

(d)        Upon discovery by the Depositor, the Guarantor, the NIMS Insurer, the Seller, the Master Servicer or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall within two Business Days give written notice thereof to the other parties. In connection therewith, the Seller or the Depositor shall repurchase or, subject to the limitations set forth in Section 2.03(c), substitute one or more Qualified Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Such repurchase or substitution shall be made by the Seller. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.03(a). The Trustee shall reconvey to the Depositor or the Seller, as the case may be, the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty.

SECTION 2.04. [Reserved].

ARTICLE III

ADMINISTRATION AND SERVICING

OF THE MORTGAGE LOANS

SECTION 3.01. Master Servicer to Act as Master Servicer.

The Master Servicer shall service and administer the Mortgage Loans on behalf of the Trustee and in the best interests of and for the benefit of the Certificateholders (as determined by the Master Servicer in its reasonable judgment) in accordance with (i) the terms of the respective Mortgage Loans and any insurance policies related thereto, (ii) all Applicable Regulations, (iii) the terms of this Agreement, (iv) the Loss Mitigation Action Plan, if applicable and (v) to the extent consistent with the preceding requirements, in the same manner in which it services and administers similar mortgage loans for its own portfolio, giving due consideration to customary and usual standards of practice of prudent mortgage lenders and loan servicers administering similar mortgage loans but without regard to:

(i)         any relationship that the Master Servicer, any Sub-Servicer or any Affiliate of the Master Servicer or any Sub-Servicer may have with the related Mortgagor;

(ii)         the ownership of any Certificate by the Master Servicer or any Affiliate of the Master Servicer;

(iii)        the Master Servicer’s obligation to make Advances or Servicing Advances; or

(iv)        the Master Servicer’s or any Sub-Servicer’s right to receive compensation for its services hereunder or with respect to any particular transaction (the “Servicing Standard”).

Subject only to the above-described servicing standards and the terms of this Agreement and of the respective Mortgage Loans, the Master Servicer shall have full power and authority, acting alone or through Sub-Servicers as provided in Section 6.06, to do or cause to be done any and all things in connection with such servicing and administration which it may deem necessary or desirable. Without limiting the generality of the foregoing, the Master Servicer in its own name or in the name of a Sub-Servicer is hereby authorized and empowered by the Trustee, in accordance with the servicing standards set forth above, (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, or of forbearance, or of modification and all other comparable instruments, with respect to the Mortgage Loans and the Mortgaged Properties, (ii) to institute foreclosure proceedings or obtain a deed-in-lieu of foreclosure to convert the ownership of such properties, and to hold or cause to be held title to such properties, in the name of the Trust Fund, on behalf of the Trustee and the Certificateholders, (iii) to market, sell and transfer title of REO Properties held in the name of the Trust Fund to third party purchasers upon terms and conditions the Master Servicer deems reasonable under the Servicing Standard, (iv) to bring or respond to civil actions or complaints (in its own name or that of the Trust Fund or the

Trustee on behalf of the Trust Fund) related to any Mortgage Loan, Mortgaged Property or REO Property held by the Trust Fund and (v) to execute any other document necessary or appropriate to enable the Master Servicer to carry out its servicing and administrative duties hereunder consistent with the Servicing Standard.

At the written request of the Master Servicer, the Trustee shall execute and furnish to the Master Servicer such documents as are necessary or appropriate to enable the Master Servicer to carry out its servicing and administrative duties hereunder. By execution of this Agreement, the Trustee, on behalf of the Trust Fund, hereby grants to the Master Servicer a power of attorney to execute any and all documents necessary to carry out any and all servicing duties described in this Agreement (including the taking of and transferring title of REO Properties to third parties held in the name of the Trustee for the benefit of the Trust) and expressly confirms that this paragraph along with the face page and a copy of the signature page (duly executed) to this Agreement shall constitute the power of attorney for evidentiary and/or recording purposes. The Trustee shall not be liable for the actions of the Master Servicer or any Sub-Servicers under such powers of attorney.

Subject to Section 3.04(d) hereof, in accordance with the Servicing Standard, the Master Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the timely payment of taxes and assessments on the Mortgaged Properties, which advances shall be Servicing Advances reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.04(d), and further as provided in Section 3.05(a). Any cost incurred by the Master Servicer or by Sub-Servicers in effecting the timely payment of taxes and assessments on a Mortgaged Property shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid Stated Principal Balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit.

Consistent with the terms of this Agreement, the Master Servicer may 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 such waiver, modification, postponement or indulgence is in conformity with the Servicing Standard; provided, however, that:

(A)       the Master Servicer shall not make future advances (except as provided in Section 4.03);

(B)        the Master Servicer shall not permit any modification with respect to any Mortgage Loan that would change the Mortgage Rate, defer or forgive the payment of any principal or interest payments, reduce the outstanding Stated Principal Balance (except for reductions resulting from actual payments of principal) or extend the final maturity date on such Mortgage Loan (unless as provided in Section 3.02, (i) the Mortgagor is in default with respect to the Mortgage Loan or (ii) such default is, in the judgment of the Master Servicer, reasonably foreseeable); and

(C)       the Master Servicer shall not consent to (i) partial releases of Mortgages, (ii) alterations, (iii) removal, demolition or division of properties subject to Mortgages, (iv) modification or (v) second mortgage subordination agreements with respect to any Mortgage Loan that would: (i) affect adversely the status of any Trust REMIC as a

REMIC, (ii) cause any Trust REMIC to be subject to a tax on “prohibited transactions” or “contributions” pursuant to the REMIC Provisions, or (iii) both (x) effect an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or Treasury regulations promulgated thereunder) and (y) cause any Trust REMIC constituting part of the Trust Fund to fail to qualify as a REMIC under the Code or the imposition of any tax on “prohibited transactions” or “contributions” after the Startup Day under the REMIC Provisions.

To the extent consistent with the terms of this Agreement, including Section 2.03 and Section 2.05, the Master Servicer may waive (or permit a Sub-Servicer to waive) a Prepayment Charge only under the following circumstances: (i) such waiver is standard and customary in servicing similar Mortgage Loans and (ii) such waiver relates to a default or a reasonably foreseeable default and would, in the reasonable judgment of the Master Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related Mortgage Loan; provided, that, any such determination shall be evidenced by an Officer’s Certificate of the Master Servicer.

The Master Servicer may delegate its responsibilities under this Agreement; provided, however, that no such delegation shall release the Master Servicer from the responsibilities or liabilities arising under this Agreement. All references to Master Servicer in this Agreement shall be deemed to include any Sub-Servicer duly appointed by the Master Servicer pursuant to this Agreement.

SECTION 3.02. Collection of Certain Mortgage Loan Payments.

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 applicable insurance policies, follow such collection procedures as it would follow with respect to mortgage loans comparable to the Mortgage Loans and held for its own account. Consistent with the foregoing, the Master Servicer may in its discretion (i) waive any late payment charge or, if applicable, penalty interest, (ii) waive any provision of any Mortgage Loan requiring the related Mortgagor to submit to mandatory arbitration with respect to disputes arising thereunder or (iii) extend the due dates for the Monthly Payments due on a Mortgage Note for a period of not greater than 180 days; provided that any extension pursuant to clause (iii) above shall not affect the amortization schedule of any Mortgage Loan for purposes of any computation hereunder. The Guarantor’s or the NIMS Insurer’s prior written consent (as provided in Section 1.03) shall be required for any modification, waiver or amendment if the aggregate number of outstanding Mortgage Loans which have been modified, waived or amended exceeds 5% of the number of Mortgage Loans as of the Cut-off Date. In the event of any such arrangement pursuant to clause (iii) above, the Master Servicer shall make timely advances on such Mortgage Loan during such extension pursuant to Section 4.03 and in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements.

Notwithstanding the foregoing, in the event that any Mortgage Loan is in default or, in the judgment of the Master Servicer, such default is reasonably foreseeable, the Master Servicer, consistent with the Servicing Standard, may also waive, modify or vary any term of

such Mortgage Loan (including modifications that would change the Mortgage Rate, forgive the payment of principal or interest or extend the final maturity date of such Mortgage Loan), accept payment from the related Mortgagor of an amount less than the Stated Principal Balance in final satisfaction of such Mortgage Loan, or consent to the postponement of strict compliance with any such term or otherwise grant indulgence to any Mortgagor (any and all such waivers, modifications, variances, forgiveness of principal or interest, postponements, or indulgences collectively referred to herein as “forbearance”) , provided, however, that in determining which course of action permitted by this sentence it shall pursue, the Master Servicer shall adhere to the Loss Mitigation Action Plan. The Master Servicer’s analysis supporting any forbearance and the conclusion that any forbearance meets the standards of Section 3.01 and the Loss Mitigation Action Plan shall be reflected in writing in the Mortgage File.

If the Class CE Certificates are no longer outstanding, the Master Servicer shall not take any action pursuant to the preceding two paragraphs with respect to a Group I Mortgage Loan without obtaining the prior written consent of the Guarantor to such modification. The Master Servicer shall submit to the Guarantor with its request for consent, such information related to the proposed modification as can be expected to be needed by the Guarantor to evaluate the Master Servicer’s request, including the terms of the proposed modification and the reasons for the Master Servicer’s decision that such Group I Mortgage Loan should be modified. The Guarantor shall be deemed to have consented to the Master Servicer’s request in the event that the Guarantor does not provide the Master Servicer with either its written consent to such requested modification or written notice of its objection to such modification within five Business Days of its receipt of the Master Servicer’s request.

In the event the Master Servicer shall deliver to the Trustee for deposit in the Distribution Account any amount not required to be deposited therein, it may at any time request that the Trustee withdraw such amount from the Distribution Account and remit to it any such amount, any provision herein to the contrary notwithstanding.

(h)        Investment of Account Funds. Funds on deposit in the Collection Account, the Distribution Account, any REO Account and any Escrow Account may be invested in Permitted Investments in accordance with the provisions set forth in Section 3.06. Any investment earnings or interest paid on funds deposited in the Collection Account, any REO Account and any Escrow Account (subject to Section 3.05(b)) shall accrue to the benefit of the Master Servicer and the Master Servicer shall be entitled to retain and withdraw such interest from each such account on a daily basis.

(j)         In order to comply with its duties under the U.S.A. Patriot Act of 2001, the Trustee shall obtain and verify certain information and documentation from the other parties to this Agreement including, but not limited to, each such party’s name, address, and other identifying information.

SECTION 3.05. Permitted Withdrawals From the Collection Account, Escrow Account and Distribution Account.

(a)        Collection Account. The Master Servicer may, from time to time, withdraw from the Collection Account for the following purposes or as described in Section 4.03:

(i)         to remit to the Trustee for deposit in the Distribution Account the amounts required to be so remitted pursuant to Section 3.04(g) or permitted to be so remitted pursuant to the last paragraph of Section 3.04(g);

(ii)         subject to Section 3.12(c), to reimburse itself for (a) any unpaid Servicing Fees, (b) any unreimbursed Servicing Advances and (c) any unreimbursed Advances, the Master Servicer’s right to reimburse itself pursuant to this subclause (ii) being limited to any Late Collections, Liquidation Proceeds, Subsequent Recoveries and Insurance Proceeds received on the related Mortgage Loan and any amounts received in respect of the rental of the related REO Property prior to an REO Disposition that represent payments of principal and/or interest respecting which any such advance was made;

(iii)        to reimburse itself for (a) any unpaid Servicing Fees to the extent not recoverable under Section 3.05(a)(ii) and (b) any unpaid Advances or Servicing Advances that have been deemed Nonrecoverable Advances or Nonrecoverable Servicing Advances;

(viii)      to reimburse the Master Servicer or the Depositor for expenses incurred by or reimbursable to the Master Servicer or the Depositor, as the case may be, pursuant to Section 6.03;

(ix)        to remit to the Trustee any amounts that the Trustee is permitted to be paid or reimbursed from the assets of the Trust Fund pursuant to the terms of this Agreement, including the terms of Section 7.02(a) and Section 8.05 of this Agreement;

(x)        to reimburse the NIMS Insurer, the Master Servicer (if the Master Servicer is not an Affiliate of the Seller) or the Trustee, as the case may be, for enforcement expenses reasonably incurred in respect of the breach or defect giving rise to the purchase obligation under Section 2.03 of this Agreement that were included in the Purchase Price of the Mortgage Loan, including any expenses arising out of the enforcement of the purchase obligation;

(xi)        to pay to the Master Servicer, the Depositor, the Seller or the Guarantor (with respect to the Group I Mortgage Loans), as the case may be, with respect to each Mortgage Loan that has previously been purchased or replaced pursuant to Section 2.03 or Section 3.16(a) all amounts received thereon subsequent to the date of purchase or substitution, as the case may be;

(xii)       to transfer funds in the Collection Account maintained at a particular depository to the Collection Account maintained at a different depository, pursuant to Section 3.04(i); and

(xiii)      to clear and terminate the Collection Account upon the termination of this Agreement.

On each Business Day as of the commencement of which the balance on deposit in the Collection Account exceeds $75,000 following any withdrawals pursuant to the next succeeding sentence, the amount of such excess shall be remitted to the Trustee, but only if the Collection Account constitutes an Eligible Account solely pursuant to clause (ii) of the definition of “Eligible Account.” If the balance on deposit in the Collection Account exceeds $75,000 as of the commencement of business on any Business Day and the Collection Account constitutes an Eligible Account solely pursuant to clause (ii) of the definition of “Eligible Account,” the Master Servicer shall, on or before 3:00 p.m. New York time on such Business Day, withdraw from the Collection Account any and all amounts payable or reimbursable to the Depositor, the Master Servicer, the Trustee or any Sub-Servicer pursuant to Section 3.05 and shall pay such amounts to the Persons entitled thereto.

The foregoing requirements for withdrawal from the Collection Account shall be exclusive. In the event the Master Servicer shall deposit in the Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from the Collection Account, any provision herein to the contrary notwithstanding.

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 Collection Account, to the extent held by or on behalf of it, pursuant to subclauses (ii), (iii), (iv), (v), (vi), (vii), (viii) and (xi) above. The Master Servicer shall provide written notification to the Trustee and the NIMS Insurer and the Guarantor on or prior to the next succeeding Master Servicer Reporting Date, upon making any withdrawals from the Collection Account pursuant to subclause (viii) above.

(b)        Escrow Account. The Master Servicer may, from time to time, withdraw from the Escrow Account for the following purposes:

(i)         to effect payments of ground rents, taxes, assessments, water rates, hazard insurance premiums and comparable items;

(ii)         to reimburse the Master Servicer for any Servicing Advance made by the Master Servicer with respect to a related Mortgage Loan but only from amounts received on the related Mortgage Loan which represent late payments or Late Collections of Escrow Payments thereunder;

(iii)        to refund to the Mortgagor any funds as may be determined to be overages;

(iv)        for transfer to the Collection Account in accordance with the terms of this Agreement;

(v) for application to restoration or repair of the Mortgaged Property;

(vi)        to pay to the Master Servicer, or to the Mortgagor to the extent required by the related Mortgage Loan or Applicable Regulations, any interest paid on the funds deposited in the Escrow Account;

(vii)       to clear and terminate the Escrow Account on the termination of this Agreement; and

(viii) to transfer to the Collection Account any Insurance Proceeds.

In the event the Master Servicer shall deposit in an Escrow Account any amount not required to be deposited therein, it may at any time withdraw such amount from such Escrow Account, any provision herein to the contrary notwithstanding. As part of its servicing duties, the Master Servicer shall pay to the Mortgagor interest on funds in the Escrow Account, to the extent required by the related Mortgage Loan or Applicable Regulations, and to the extent that interest earned on funds in the Escrow Account is insufficient, shall pay such interest from its own funds, without any reimbursement therefor. The Master Servicer may pay to itself any excess interest on funds in the Escrow Account, to the extent such action is in conformity with the Servicing Standard, is permitted by law and such amounts are not required to be paid to Mortgagors or used for any of the other purposes set forth above.

(c)        Distribution Account. The Trustee shall, from time to time, make withdrawals from the Distribution Account, for any of the following purposes:

(i)         to make distributions to the Swap Account in accordance with Section 4.10;

(ii)         to make distributions to Certificateholders and the Guarantor in accordance with Section 4.01;

(iii) to pay to itself amounts to which it is entitled pursuant to Section 8.05;

(iv)        to pay itself any interest income earned on funds deposited in the Distribution Account pursuant to Section 3.06;

(v) to reimburse itself pursuant to Section 7.01 and Section 7.02(b);

(vi)        to pay any amounts in respect of taxes pursuant to Section 10.01(g)(iii); and

(vii)       to reimburse the NIMS Insurer for Net Swap Payments paid by the NIMS Insurer to the Swap Provider pursuant to Section 4.10 (only to the extent the Trustee’s failure to make distributions in accordance with Section 3.05(c)(i) is not due to insufficient funds in the Distribution Account); and

(viii) to clear and terminate the Distribution Account pursuant to Section 9.01.

SECTION 3.06. Investment of Funds in the Collection Account, the Escrow Account, the REO Account and the Distribution Account.

(a)        The Master Servicer may direct any depository institution maintaining the Collection Account, the Escrow Account (subject to Section 3.05(b)), and the REO Account and the Trustee may direct any depository institution maintaining the Distribution Account (for purposes of this Section 3.06, each an “Investment Account”), to invest the funds in such Investment Account in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Trustee is the obligor thereon, and (ii) no later than the date on which such funds are required to be withdrawn from such Investment Account pursuant to this Agreement, if the Trustee is the obligor thereon. All such Permitted Investments shall be held to maturity, unless payable on demand. Any investment of funds in an Investment Account shall be made in the name of the Trustee (in its capacity as such) or in the name of a nominee of the Trustee. The Trustee shall be entitled to sole possession (except with respect to investment direction of funds held in the Collection Account, the Escrow Account, and the REO Account) over each such investment and (except with respect to the income on funds held in the Collection Account, the Escrow Account and the REO Account) the income thereon, and any certificate or other instrument evidencing any such investment shall be delivered directly to the Trustee or its agent, together with any document of transfer necessary to transfer title to such investment to the Trustee or its nominee. In the event amounts on deposit in an Investment Account are at any time invested in a Permitted Investment payable on demand, the Trustee shall:

(i)         consistent with any notice required to be given thereunder, demand that payment thereon be made on the last day such Permitted Investment may otherwise mature hereunder in an amount equal to the lesser of (1) all amounts then payable thereunder and (2) the amount required to be withdrawn on such date; and

(ii)         demand payment of all amounts due thereunder promptly upon determination by a Responsible Officer of the Trustee that such Permitted Investment would not constitute a Permitted Investment in respect of funds thereafter on deposit in the Investment Account.

(b)        All income in the nature of interest from the investment of funds in the Collection Account, the Escrow Account (subject to Section 3.05(b)) and the REO Account shall be for the benefit of the Master Servicer as compensation for the Master Servicer’s services pursuant to this Agreement. The Master Servicer shall deposit in the Collection Account, the Escrow Account, and the REO Account, as applicable, from its own funds the amount of any loss incurred in respect of any such Permitted Investment made with funds in such account immediately upon realization of such loss.

(c)        All income in the nature of interest or earnings from the investment of funds in the Distribution Account shall be for the benefit of the Trustee as compensation for the Trustee’s services pursuant to this Agreement. The Trustee shall deposit in the Distribution

Account from its own funds the amount of any loss incurred on Permitted Investments in the Distribution Account.

(d)        Funds on deposit in the Net WAC Rate Carryover Reserve Account may be invested in Permitted Investments in accordance with this Section 3.06 subject to any limitations set forth in Section 4.10 (with respect to the Net WAC Rate Carryover Reserve Account) and any investment earnings or interest paid shall accrue to the benefit of the party designated in such section and the party so designated shall deposit in the related account from its own funds the amount of any loss incurred on Permitted Investments in such account.

(e)        Except as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment, or if a default occurs in any other performance required under any Permitted Investment, the Trustee may and, subject to Section 8.01 and Section 8.02(a)(v), upon the request of the NIMS Insurer, the Guarantor or the Holders of Certificates representing more than 50% of the Voting Rights allocated to any Class of Certificates, shall take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings.

(f)         The Trustee or its Affiliates are permitted to receive compensation that could be deemed to be in the Trustee’s economic self-interest for (i) serving as investment adviser, administrator, shareholder, servicing agent, custodian or sub-custodian with respect to certain of the Permitted Investments, (ii) using Affiliates to effect transactions in certain Permitted Investments and (iii) effecting transactions in certain Permitted Investments. Such compensation shall not be considered an amount that is reimbursable or payable pursuant to Section 3.05.

SECTION 3.07. Payment of Taxes, Insurance and Other Charges.

With respect to each Mortgage Loan, the Master Servicer shall maintain accurate records reflecting the status of ground rents, taxes, assessments, water rates and other charges which are or may become a lien upon the Mortgaged Property and the status of fire and hazard insurance coverage and, as to those Mortgage Loans subject to a voluntary escrow agreement, shall obtain, from time to time, all bills for the payment of such charges (including renewal premiums) and shall effect payment thereof prior to the applicable penalty or termination date and at a time appropriate for securing maximum discounts allowable, employing for such purpose deposits of the Mortgagor in the Escrow Account which shall have been estimated and accumulated by the Master Servicer in amounts sufficient for such purposes, as allowed under the terms of the Mortgage or Applicable Regulations. The Master Servicer assumes full responsibility for the timely payment of all such bills and shall effect timely payments of all such bills irrespective of the Mortgagor’s faithful performance in the payment of same or the making of the Escrow Payments and shall make Servicing Advances from its own funds to effect such payments. To the extent that the Mortgage does not provide for Escrow Payments, the Master Servicer shall use reasonable efforts consistent with the Servicing Standard to determine that any such payments are made by the Mortgagor at the time they first become due and shall ensure that the Mortgaged Property is not lost to a tax lien as a result of nonpayment and that such Mortgaged Property is not left uninsured.

SECTION 3.08. Maintenance of Hazard Insurance.

The Master Servicer shall cause to be maintained for each Mortgage Loan fire insurance with extended coverage on the related Mortgaged Property in an amount which is at least equal to the least of (i) the current Stated Principal Balance of such Mortgage Loan, (ii) the amount necessary to fully compensate for any damage or loss to the improvements that are a part of such property on a replacement cost basis and (iii) the maximum insurable value of the improvements which are a part of such Mortgaged Property, in each case in an amount not less than such amount as is necessary to avoid the application of any coinsurance clause contained in the related hazard insurance policy. The Master Servicer shall also cause to be maintained fire insurance with extended coverage on each REO Property in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements which are a part of such property and (ii) the outstanding Stated Principal Balance of the related Mortgage Loan, plus accrued interest at the Mortgage Rate and related Servicing Advances (each measured at the time it became an REO Property). The Master Servicer shall comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any such hazard policies. Any amounts to be collected by the Master Servicer under any such policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or amounts to be released to the Mortgagor in accordance with the procedures that the Master Servicer would follow in servicing loans held for its own account, subject to the terms and conditions of the related Mortgage and Mortgage Note) shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.05, if received in respect of a Mortgage Loan, or in the REO Account, subject to withdrawal pursuant to Section 3.13, if received in respect of an REO Property. Any cost incurred by the Master Servicer in maintaining any such insurance shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid Stated Principal Balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If the Mortgaged Property or REO Property is at any time in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards, the Master Servicer shall cause to be maintained a flood insurance policy in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the unpaid Stated Principal Balance of the related Mortgage Loan; (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); and (iii) the maximum insurable value of the improvements which are part of the related Mortgaged Property.

SECTION 3.09. Maintenance of Mortgage Blanket Insurance.

In the event that the Master Servicer shall obtain and maintain a blanket policy with an insurer having a General Policy Rating of “A:V” or better in Best’s Key Rating Guide (or such other rating that is comparable to such rating) 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 two sentences of Section 3.08, 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 or REO Property a policy complying with the first two sentences of Section 3.08, and there shall have been one or more losses which would have been covered by such policy, deposit to the Collection Account from its own funds the amount not otherwise payable under the blanket policy because of such deductible clause. In connection with its activities as administrator and servicer of the Mortgage Loans, the Master Servicer agrees to prepare and present, on behalf of itself, the Trustee and the Certificateholders, claims under any such blanket policy in a timely fashion in accordance with the terms of such policy.

SECTION 3.10. Fidelity Bond; Errors and Omissions Insurance.

The Master Servicer shall keep in force during the term of this Agreement a policy or policies of insurance covering errors and omissions for failure in the performance of the Master Servicer’s obligations under this Agreement, which policy or policies shall be in such form and amount that would meet the requirements of Fannie Mae or Freddie Mac if it were the purchaser of the Mortgage Loans, unless the Master Servicer has obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall also maintain a fidelity bond in the form and amount that would meet the requirements of Fannie Mae or Freddie Mac, unless the Master Servicer has obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall provide the Trustee, the Guarantor (upon reasonable request) and the NIMS Insurer (upon reasonable request) with copies of any such insurance policies and fidelity bond. The Master Servicer shall be deemed to have complied with this provision if an Affiliate of the Master Servicer has such errors and omissions and fidelity bond coverage and, by the terms of such insurance policy or fidelity bond, the coverage afforded thereunder extends to the Master Servicer. Any such errors and omissions policy and fidelity bond shall by its terms not be cancelable without thirty days’ prior written notice to the Trustee. The Master Servicer shall also cause each Sub-Servicer to maintain a policy of insurance covering errors and omissions and a fidelity bond which would meet such requirements.

SECTION 3.11. Enforcement of Due-On-Sale Clauses; Assumption Agreements.

The Master Servicer shall, to the extent it has knowledge of any conveyance or prospective conveyance of any Mortgaged Property by any Mortgagor (whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains or is to remain liable under the Mortgage Note and/or the Mortgage), exercise its rights to accelerate the maturity of such Mortgage Loan under the “due-on-sale” clause, if any, applicable thereto; provided, however, that the Master Servicer shall not exercise any such rights if prohibited by law from doing so. If the Master Servicer reasonably believes it is unable under applicable law to enforce such “due-on-sale” clause, or if any of the other conditions set forth in the proviso to the preceding sentence apply, the Master Servicer is authorized to enter into an assumption and modification agreement from or with the person to whom such property has been conveyed or is proposed to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, to the extent permitted by applicable state law, the Mortgagor remains liable thereon. The Master Servicer is also authorized to enter into a substitution of liability agreement with such person, pursuant to which the original Mortgagor is released from liability and such person is substituted as the Mortgagor and becomes liable under the Mortgage Note, provided that no

such substitution shall be effective unless such person satisfies the underwriting criteria of the Master Servicer. In connection with any assumption or substitution, the Master Servicer shall apply such underwriting standards and follow such practices and procedures as shall be normal and usual in its general mortgage servicing activities and as it applies to other mortgage loans owned solely by it. The Master Servicer shall not take or enter into any assumption and modification agreement, however, unless (to the extent practicable in the circumstances) it shall have received confirmation, in writing, of the continued effectiveness of any applicable hazard insurance policy, or a new policy meeting the requirements of this Section is obtained. Any fee collected by the Master Servicer in respect of an assumption or substitution of liability agreement shall be retained by the Master Servicer as additional servicing compensation. In connection with any such assumption, no material term of the Mortgage Note (including but not limited to the related Mortgage Rate and the amount of the Monthly Payment) may be amended or modified, except as otherwise required pursuant to the terms thereof or otherwise permitted under Section 3.01. The Master Servicer shall notify the Trustee, the Guarantor and any respective Custodian that any such substitution, assumption and modification agreement has been completed by forwarding to the Trustee (with a copy to the Guarantor) or to such Custodian, as the case may be, the executed original of such substitution or assumption agreement, which document shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. If the Class CE Certificates are no longer outstanding, the Master Servicer shall not take or enter into any substitution, assumption or modification agreement with respect to a Group I Mortgage Loan without obtaining the prior written consent of the Guarantor to such substitution, assumption or modification agreement. The Master Servicer shall submit to the Guarantor with its request for consent, such information related to the proposed substitution, assumption or modification agreement as can be expected to be needed by the Guarantor to evaluate the Master Servicer’s request, including the terms of the proposed substitution, assumption or modification and the reasons for the Master Servicer’s decision that such substitution, assumption or modification agreement should be taken or entered into with respect to such Group I Mortgage Loan. The Guarantor shall be deemed to have consented to the Master Servicer’s request in the event that the Guarantor does not provide the Master Servicer with either its written consent to such requested substitution, assumption or modification agreement or written notice of its objection to such substitution, assumption or modification agreement within five Business Days of its receipt of the Master Servicer’s request. Such requests shall be sent to the Guarantor at: Fannie Mae, Special Products Group, Mail Stop 5H-5W-03, 13150 Worldgate Drive, Herndon, Virginia 20170, Attention: Director. With respect to each substitution, assumption or modification agreement which is entered into with the consent of the Guarantor, the Master Servicer shall give written notice to the NIMS Insurer to the addresses set forth in Section 11.05, to the Guarantor to the following address: Fannie Mae, Special Products Group, Mail Stop 5H-5W-03, 13150 Worldgate Drive, Herndon, Virginia 20170, Attention: Director. Such notice shall be delivered within thirty Business Days following the date of such substitution, assumption or modification agreement.

Notwithstanding the foregoing paragraph or any other provision of this Agreement, the Master Servicer shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any assumption of a Mortgage Loan by operation of law or by the terms of the Mortgage Note or any assumption which the Master Servicer may be restricted by law from preventing, for any reason whatever. For purposes of this

Section 3.11, the term “assumption” is deemed to also include a sale (of the Mortgaged Property) subject to the Mortgage that is not accompanied by an assumption or substitution of liability agreement.

SECTION 3.12. Realization Upon Defaulted Mortgage Loans.

(a)        The Master Servicer shall, consistent with the Servicing Standard and the Loss Mitigation Action Plan, foreclose upon or otherwise comparably convert 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 3.02. The Master Servicer shall be responsible for all costs and expenses incurred by it in any such proceedings; provided, however, that such costs and expenses shall be recoverable as Servicing Advances by the Master Servicer as contemplated in Section 3.05 and Section 3.13. The foregoing is subject to the provision that, in any case in which Mortgaged Property shall have suffered damage from an Uninsured Cause, the Master Servicer shall not be required to expend its own funds toward the restoration of such property unless it shall determine in its discretion that such restoration shall increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself for such expenses.

(b)        Notwithstanding the foregoing provisions of this Section 3.12 or any other provision of this Agreement, with respect to any Mortgage Loan as to which the Master Servicer has received actual notice of, or has actual knowledge of, the presence of any toxic or hazardous substance on the related Mortgaged Property, the Master Servicer shall not, on behalf of the Trustee, either (i) obtain title to such Mortgaged Property as a result of or in lieu of foreclosure or otherwise or (ii) otherwise acquire possession of, or take any other action with respect to, such Mortgaged Property, if, as a result of any such action, the Trustee, the Trust Fund or the Certificateholders would be considered to hold title to, to be a “mortgagee-in-possession” of, or to be an “owner” or “operator” of such Mortgaged Property within the meaning of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended from time to time, or any comparable law, unless the Master Servicer has also previously determined, based on its reasonable judgment and a report prepared by a Person who regularly conducts environmental audits using customary industry standards, that:

(i)         such Mortgaged Property is in compliance with applicable environmental laws or, if not, that it would be in the best economic interest of the Trust Fund to take such actions as are necessary to bring the Mortgaged Property into compliance therewith; and

(ii)         there are no circumstances present at such Mortgaged Property relating to the use, management or disposal of any hazardous substances, hazardous materials, hazardous wastes, or petroleum-based materials for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any federal, state or local law or regulation, or that if any such materials are present for which such action could be required, that it would be in the best economic interest of the Trust Fund to take such actions with respect to the affected Mortgaged Property.

Notwithstanding the foregoing, if such environmental audit reveals, or if the Master Servicer has actual knowledge or notice, that such Mortgaged Property contains such

toxic or hazardous wastes or substances, the Master Servicer shall not foreclose or accept a deed in lieu of foreclosure without the prior written consent of the Guarantor with respect to the Group I Mortgage Loans (which consent shall not be unreasonably withheld) and the NIMS Insurer.

The cost of the environmental audit report contemplated by this Section 3.12 shall be advanced by the Master Servicer, subject to the Master Servicer’s right to be reimbursed therefor from the Collection Account as provided in Section 3.05(a)(v), such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans.

If the Master Servicer determines, as described above, that it is in the best economic interest of the Trust Fund to take such actions as are necessary to bring any such Mortgaged Property into compliance with applicable environmental laws, or to take such action with respect to the containment, clean-up or remediation of hazardous substances, hazardous materials, hazardous wastes or petroleum-based materials affecting any such Mortgaged Property, then the Master Servicer shall take such action as it deems to be in the best economic interest of the Trust Fund; provided, however, that the Master Servicer shall not proceed with foreclosure or acceptance of a deed in lieu of foreclosure if the estimated costs of the environmental clean up, as estimated in the environmental audit report, together with the Advances made by the Master Servicer and the estimated costs of foreclosure or acceptance of a deed in lieu of foreclosure exceeds the estimated value of the Mortgaged Property. The cost of any such compliance, containment, cleanup or remediation shall be advanced by the Master Servicer, subject to the Master Servicer’s right to be reimbursed therefor from the Collection Account as provided in Section 3.05(a)(v), such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans.

(c)        Proceeds received in connection with any Final Recovery Determination, as well as any recovery resulting from a partial collection of Insurance Proceeds, Subsequent Recoveries or Liquidation Proceeds, in respect of any Mortgage Loan, shall be applied in the following order of priority: first, to reimburse the Master Servicer or any Sub-Servicer for any related unreimbursed Servicing Advances and Advances, pursuant to Section 3.05(a)(ii); second, to accrued and unpaid interest on the Mortgage Loan, to the date of the Final Recovery Determination, or to the Due Date prior to the Distribution Date on which such amounts are to be distributed if not in connection with a Final Recovery Determination; and third, as a recovery of principal of the Mortgage Loan. If the amount of the recovery so allocated to interest is less than the full amount of accrued and unpaid interest due on such Mortgage Loan, the amount of such recovery shall be allocated by the Master Servicer as follows: first, to unpaid Servicing Fees; and second, to the balance of the interest then due and owing. The portion of the recovery so allocated to unpaid Servicing Fees shall be reimbursed to the Master Servicer or any Sub-Servicer pursuant to Section 3.05(a)(ii).

SECTION 3.13. Title, Management and Disposition of REO Property.

(a)        The deed or certificate of sale of any REO Property shall be taken in the name of the Trustee, or its nominee, in trust for the benefit of the Certificateholders. Pursuant to the power of attorney granted in Section 3.01, the Master Servicer is hereby authorized to

transfer the title of any REO Property taken in the name of the Trustee to a third party purchaser pursuant to this Section 3.13 without further documentation of its authority as attorney-in-fact for the Trustee on behalf of the Trust. The Master Servicer, on behalf of the Trust Fund (and on behalf of the Trustee for the benefit of the Certificateholders), shall either sell any REO Property before the close of the third taxable year after the year the Trust Fund acquires ownership of such REO Property for purposes of Section 860G(a)(8) of the Code or request from the Internal Revenue Service, no later than 60 days before the day on which the three-year grace period would otherwise expire, an extension of the three-year grace period, unless the Master Servicer shall have delivered to the Trustee, the NIMS Insurer, the Guarantor and the Depositor an Opinion of Counsel, addressed to the Trustee, the NIMS Insurer, the Guarantor and the Depositor, to the effect that the holding by the Trust Fund of such REO Property subsequent to three years after its acquisition shall not result in the imposition on any Trust REMIC of taxes on “prohibited transactions” thereof, as defined in Section 860F of the Code, or cause any Trust REMIC to fail to qualify as a REMIC under Federal law at any time that any Certificates are outstanding. The Master Servicer shall manage, conserve, protect and operate each REO Property for the benefit of the Certificateholders and solely for the purpose of its prompt disposition and sale in a manner which does not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or result in the receipt by any Trust REMIC of any “income from non-permitted assets” within the meaning of Section 860F(a)(2)(B) of the Code, or any “net income from foreclosure property” which is subject to taxation under the REMIC Provisions.

(b)        The Master Servicer shall segregate and hold all funds collected and received in connection with the operation of any REO Property separate and apart from its own funds and general assets and shall establish and maintain with respect to REO Properties an account held in trust for the Trustee for the benefit of the Certificateholders (the “REO Account”), which shall be an Eligible Account. The Master Servicer shall be permitted to allow the Collection Account to serve as the REO Account, subject to separate ledgers for each REO Property. The Master Servicer shall be entitled to retain or withdraw any interest income paid on funds deposited in the REO Account.

(c)        The Master Servicer shall have full power and authority, subject only to the specific requirements and prohibitions of this Agreement, to do any and all things in connection with any REO Property as are consistent with the manner in which the Master Servicer manages and operates similar property owned by the Master Servicer or any of its Affiliates, all on such terms and for such period as the Master Servicer deems to be in the best interests of Certificateholders and appropriate to effect the prompt disposition and sale of the REO Property. In connection therewith, the Master Servicer shall deposit, or cause to be deposited in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Master Servicer’s receipt thereof, and shall thereafter deposit in the REO Account, in no event more than two Business Days after the deposit of such funds into the clearing account, all revenues received by it with respect to an REO Property and shall withdraw therefrom funds necessary for the proper operation, management and maintenance of such REO Property including, without limitation:

(i) all insurance premiums due and payable in respect of such REO Property;

(ii)         all real estate taxes and assessments in respect of such REO Property that may result in the imposition of a lien thereon; and

(iii) all costs and expenses necessary to maintain such REO Property.

To the extent that amounts on deposit in the REO Account with respect to an REO Property are insufficient for the purposes set forth in clauses (i) through (iii) above with respect to such REO Property, the Master Servicer shall advance from its own funds such amount as is necessary for such purposes if, but only if, the Master Servicer would make such advances if the Master Servicer owned the REO Property and if in the Master Servicer’s judgment, the payment of such amounts shall be recoverable from the rental or sale of the REO Property.

Notwithstanding the Master Servicer’s obligation to the Certificateholders to manage and operate (including the collection of rents from existing tenants and management of any leases acquired with the REO property to the extent applicable) the REO Property from the date of acquisition until the date of sale, neither the Master Servicer nor the Trustee shall knowingly:

(i)         authorize the Trust Fund to enter into, renew or extend any New Lease with respect to any REO Property, if the New Lease by its terms shall give rise to any income that does not constitute Rents from Real Property;

(ii)         authorize any amount to be received or accrued under any New Lease other than amounts that shall constitute Rents from Real Property;

(iii)        authorize any construction on any REO Property, other than the completion of a building or other improvement thereon, and then only if more than ten percent of the construction of such building or other improvement was completed before default on the related Mortgage Loan became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or

(iv)        authorize any Person to Directly Operate any REO Property on any date more than 90 days after its date of acquisition by the Trust Fund;

unless, in any such case, the Master Servicer has obtained an Opinion of Counsel, provided to the Trustee and the NIMS Insurer and the Guarantor, to the effect that such action shall not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code at any time that it is held by the Trust Fund, and (B) the Master Servicer has received written notice from the Trustee that it has received written consent from the Guarantor and the NIMS Insurer (which consent shall not be unreasonably withheld) that the specific action may be taken.

The Master Servicer may contract with any Independent Contractor for the operation and management of any REO Property, provided that:

(i)         the terms and conditions of any such contract shall not be inconsistent herewith;

(ii)         any such contract shall require, or shall be administered to require, that the Independent Contractor pay all costs and expenses incurred in connection with the operation and management of such REO Property, including those listed above and remit all related revenues (net of such costs and expenses) to the Master Servicer as soon as practicable, but in no event later than thirty days following the receipt thereof by such Independent Contractor;

(iii)        none of the provisions of this Section 3.13(c) relating to any such contract or to actions taken through any such Independent Contractor shall be deemed to relieve the Master Servicer of any of its duties and obligations to the Trustee on behalf of the Certificateholders with respect to the operation and management of any such REO Property; and

(iv)        the Master Servicer shall be obligated with respect thereto to the same extent as if it alone were performing all duties and obligations in connection with the operation and management of such REO Property.

The Master Servicer shall be entitled to enter into any agreement with any Independent Contractor performing services for it related to its duties and obligations hereunder for indemnification of the Master Servicer by such Independent Contractor, and nothing in this Agreement shall be deemed to limit or modify such indemnification. The Master Servicer shall be solely liable for all fees owed by it to any such Independent Contractor, irrespective of whether the Master Servicer’s compensation pursuant to Section 3.18 is sufficient to pay such fees. The Master Servicer shall not engage an Independent Contractor to engage in any activities that the Master Servicer would not be permitted to engage in itself in accordance with the other provisions of this Agreement (including the Loss Mitigation Action Plan).

(d)        In addition to the withdrawals permitted under Section 3.13(c), the Master Servicer may from time to time make withdrawals from the REO Account for any REO Property: (i) to pay itself or any Sub-Servicer unpaid Servicing Fees in respect of the related Mortgage Loan; and (ii) to reimburse itself or any Sub-Servicer for unreimbursed Servicing Advances and Advances made in respect of such REO Property or the related Mortgage Loan. On the Master Servicer Remittance Date, the Master Servicer shall withdraw from each REO Account maintained by it and deposit into the Distribution Account in accordance with Section 3.04(g)(ii), for distribution on the related Distribution Date in accordance with Section 4.01, the income from the related REO Property received during the prior calendar month, net of any withdrawals made pursuant to Section 3.13(c) or this Section 3.13(d).

(e)        Subject to the time constraints set forth in Section 3.13(a) (including the constraint that the Master Servicer hold and manage each REO Property “solely for the purpose of its prompt disposition”) each REO disposition shall be carried out by the Master Servicer at such price and upon such terms and conditions as shall be in conformity with the requirements of the Loss Mitigation Action Plan and as shall be normal and usual in its general servicing activities for similar properties.

(f)         The proceeds from the REO Disposition, net of any amount required by law to be remitted to the Mortgagor under the related Mortgage Loan and net of any payment or reimbursement to the Master Servicer or any Sub-Servicer as provided above, shall be deposited in the Distribution Account in accordance with Section 3.04(g)(ii) on the Master Servicer Remittance Date in the month following the receipt thereof for distribution on the related Distribution Date in accordance with Section 4.01. Any REO Disposition shall be for cash only (unless changes in the REMIC Provisions made subsequent to the Startup Day allow a sale for other consideration).

SECTION 3.14 Agreement to Appoint a Special Servicer.

(a)        The Guarantor may require the Master Servicer, with prior notice to the Trustee, to enter into a special subservicing agreement with a servicer with expertise in servicing delinquent mortgage loans as designated by the Guarantor (the “Special Servicer”) on or after the earliest Distribution Date with respect to which the Certificate Principal Balance of the Class CE Certificates has been reduced to zero. Such special subservicing agreement shall relate to the servicing of only Group I Mortgage Loans that (x) have been delinquent in payment with respect to three or more Monthly Payments (provided, however, that the third such Monthly Payment shall not be deemed to be delinquent for purposes of this clause (x) until the close of business on the last day of the month in which such Monthly Payment first became due) and (y) have been transferred to the Special Servicer in accordance with this Section 3.14 and the related special subservicing agreement (a “Specially Serviced Mortgage Loan”).

(b)        The special subservicing agreement shall be consistent with the provisions of this Agreement, including but not limited to this Section 3.14, Section 6.06(a), Section 6.06(b) and Section 6.11, except as provided otherwise in this Section 3.14. In addition, the special subservicing agreement shall be on terms which shall be reasonably acceptable to the Guarantor and the Master Servicer and shall provide, at a minimum that:

(1)        the Special Servicer shall at all times meet the eligibility criteria described in Section 6.06(a);

(2)        the Special Servicer shall service only the Specially Serviced Mortgage Loans in a manner consistent with the provisions with this Agreement except as provided otherwise in the special subservicing agreement;

(3)        the Special Servicer shall use the Fannie Mae foreclosure network (and pay the customary fees therefor) for foreclosures and bankruptcies relating to Specially Serviced Mortgage Loans;

(4)        the Special Servicer shall use the Fannie Mae disposition service (and pay the customary fees therefor) for the disposition of REO Property related to Specially Serviced Mortgage Loans;

(5)        the Special Servicer shall make Advances and Servicing Advances on the Specially Serviced Mortgage Loans to the same extent and in the same manner as the Master Servicer with respect to the Group I Mortgage Loans pursuant to this Agreement;

(6)        the Special Servicer shall be entitled to receive the Servicing Fee with respect to all Specially Serviced Mortgage Loans;

(7)        prior to the transfer of servicing to the Special Servicer, the Master Servicer and the Special Servicer shall have provided all notices relating to such transfer of servicing as required to be delivered to the borrowers by applicable state and federal law;

(8)        the Special Servicer shall indemnify the Master Servicer and the Trustee for any liabilities to them arising from failures of the Special Servicer to perform its obligations according to the terms of the subservicing agreement;

(9)        the Master Servicer shall promptly give notice thereof to the Trustee, the NIMS Insurer and the Guarantor of the transfer of servicing to the Special Servicer, including the loan number together with the borrower’s name and the unpaid Stated Principal Balance of the transferred Mortgage Loan at the time of transfer;

(10)      each of the respective obligations, duties, and liabilities of the Master Servicer and the Special Servicer (or either of them) with respect to the servicing of the Specially Serviced Mortgage Loans that have arisen prior to the date on which the servicing of such Specially Serviced Mortgage Loan was transferred to the Special Servicer (the “Effective Date”), or that arise on and after the Effective Date, under this Agreement and the subservicing agreement and that remain unperformed or unsatisfied shall survive any transfer of servicing;

(11)      once a Group I Mortgage Loan becomes a Specially Serviced Mortgage Loan, such Mortgage Loan shall remain a Specially Serviced Mortgage Loan, and shall continue to be serviced by the Special Servicer, until the earlier of the liquidation or other disposition of such Mortgage Loan or the termination of the subservicing agreement, regardless of delinquency status or otherwise;

(12)      the Guarantor may remove the Special Servicer if the Special Servicer at any time fails to meet any of the above criteria or otherwise, in the judgment of the Guarantor, fails to perform according to the terms of the subservicing agreement and the provisions of this Section 3.14; provided that prior to any such removal the Guarantor shall designate a successor Special Servicer meeting the requirements of this Section 3.14, and no removal of a Special Servicer shall be effective until a successor Special Servicer has entered into a special subservicing agreement meeting the requirements of this Section 3.14 and agreed to assume the duties of the Special Servicer or the Master Servicer has undertaken such duties; and

(13)      in connection with any transfer of a Group I Mortgage Loan to the Special Servicer as a Specially Serviced Mortgage Loan, the Master Servicer shall execute any appropriate assignments or other documents reasonable and necessary to further the prosecution of the Special Servicer obligations under the special subservicing agreement.

SECTION 3.15. Reports of Foreclosure and Abandonment of Mortgaged Properties.

The Master Servicer shall file information returns with respect to the receipt of mortgage interest received in a trade or business, reports of foreclosures and abandonments of any Mortgaged Property and cancellation of indebtedness income with respect to any Mortgaged Property as required by Sections 6050H, 6050J and 6050P of the Code, respectively. 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 3.16. Optional Purchase of Defaulted Mortgage Loans.

(a)         (i) The NIMS Insurer or the Guarantor (only with respect to the Group I Mortgage Loans) may, at its option, purchase a Mortgage Loan which has become 90 or more days delinquent or for which the Master Servicer has accepted a deed in lieu of foreclosure. Prior to purchase pursuant to this Section 3.16(a)(i), the Master Servicer shall be required to continue to make Advances pursuant to Section 4.03. The NIMS Insurer or the Guarantor, as applicable, shall not use any procedure in selecting Mortgage Loans to be repurchased which is materially adverse to the interests of the Certificateholders. The NIMS Insurer or the Guarantor, as applicable, shall purchase such delinquent Mortgage Loan at a price equal to the Purchase Price of such Mortgage Loan. Any such purchase of a Mortgage Loan pursuant to this Section 3.16(a)(i) shall be accomplished by remittance to the Master Servicer for deposit in the Collection Account of the amount of the Purchase Price. The Trustee shall effectuate the conveyance of such delinquent Mortgage Loan to the NIMS Insurer or the Guarantor, as applicable, to the extent necessary, as requested, and the Trustee shall promptly deliver all documentation to the NIMS Insurer or the Guarantor, as applicable.

(i)         During the first full calendar month (but excluding the last Business Day thereof) following a Mortgage Loan or related REO Property becoming 90 days or more delinquent, the Master Servicer shall have the option, but not the obligation to purchase from the Trust Fund any such Mortgage Loan or related REO Property that is then still 90 days or more delinquent, which the Master Servicer determines in good faith shall otherwise become subject to foreclosure proceedings (evidence of such determination to be delivered in writing to the Trustee prior to purchase), at a price equal to the Purchase Price. The Purchase Price for any Mortgage Loan or related REO Property purchased hereunder shall be deposited in the Collection Account, and the Trustee, upon written certification of such deposit, shall release or cause to be released to the Master Servicer the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Master Servicer shall furnish and as shall be necessary to vest in the Master Servicer title to any Mortgage Loan or related REO Property released pursuant hereto.

(b)        If with respect to any delinquent Mortgage Loan or related REO Property, the option of the Master Servicer set forth in the preceding paragraph shall have arisen but the Master Servicer shall have failed to exercise such option on or before the Business Day preceding the last Business Day of the calendar month following the calendar month during

which such Mortgage Loan or related REO Property first became 90 days or more delinquent, then such option shall automatically expire; provided, however, that if any such Mortgage Loan or related REO Property shall cease to be 90 days or more delinquent but then subsequently shall again become 90 days or more delinquent, then the Master Servicer shall be entitled to another repurchase option with respect to such Mortgage Loan or REO Property as provided in the preceding paragraph.

SECTION 3.17. Trustee to Cooperate; Release of Mortgage Files.

(a)        Upon the payment in full of any Mortgage Loan, or the receipt by the Master Servicer of a notification that payment in full shall be escrowed in a manner customary for such purposes, the Master Servicer shall promptly notify the Trustee and any related Custodian by a certification in the form of Exhibit E or such other form supplied by the Master Servicer provided that it does not differ from the substantive content of Exhibit E (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 Collection Account pursuant to Section 3.04(b) have been or shall be so deposited) of a Servicing Officer and shall request delivery to it of the Mortgage File. Upon receipt of such certification and request, the Trustee or such Custodian, as the case may be, shall promptly release (and in no event more than three (3) Business Days thereafter) the related Mortgage File to the Master Servicer. No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Collection Account or the Distribution Account.

(b)        From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, including, for this purpose, collection under any insurance policy relating to the Mortgage Loans, the Trustee and any related Custodian shall, upon request of the Master Servicer and delivery to the Trustee or such Custodian, as the case may be, of a Request for Release in the form of Exhibit E or such other form supplied by the Master Servicer provided that it does not differ from the substantive content of Exhibit E, release the related Mortgage File to the Master Servicer, and the Trustee shall, at the direction of the Master Servicer, execute such documents as shall be necessary to the prosecution of any such proceedings and the Master Servicer shall retain such Mortgage File in trust for the benefit of the Certificateholders. Such Request for Release shall obligate the Master Servicer to return each and every document previously requested from the Mortgage File to the Trustee or to such Custodian when the need therefor by the Master Servicer no longer exists, unless the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Collection Account or 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 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. Upon receipt of a certificate of a Servicing Officer stating that such Mortgage Loan was liquidated and that all amounts received or to be received in connection with such liquidation that are required to be deposited into the Collection Account have been so deposited, or that such Mortgage Loan has become an REO Property, upon request, a copy of the Request for Release shall be released by the Trustee or such Custodian to the Master Servicer.

(c)        Upon written certification of a Servicing Officer, the Trustee shall execute and deliver to the Master Servicer any court pleadings, requests for trustee’s sale or other documents reasonably 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. Each such certification shall include a request that such pleadings or documents be executed by the Trustee and a statement as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee shall not 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.

(d)        The Trustee (or to the extent applicable, the Custodian on behalf of the Trustee) and the Master Servicer may mutually agree on policies and procedures (commercially reasonable in nature) to allow the submission of any and all requests for the release of a Mortgage File electronically with a digital signature or other identifier to designate the Servicing Officer of the Master Servicer requesting such collateral.

SECTION 3.18. Servicing Compensation.

As compensation for the activities of the Master Servicer hereunder, the Master Servicer shall be entitled to the Servicing Fee with respect to each Mortgage Loan payable solely from payments of interest in respect of such Mortgage Loan, subject to Section 4.03(e). In addition, the Master Servicer shall be entitled to recover unpaid Servicing Fees out of Insurance Proceeds, Subsequent Recoveries or Liquidation Proceeds to the extent permitted by Section 3.05(a)(ii), out of general funds in the Collection Account to the extent permitted by Section 3.05(a) and out of amounts derived from the operation and sale of an REO Property to the extent permitted by Section 3.13. The right to receive the Servicing Fee may not be transferred in whole or in part except in connection with the transfer of all of the Master Servicer’s responsibilities and obligations under this Agreement.

Additional servicing compensation in the form of assumption fees, late payment charges, insufficient funds fees, reconveyance fees and other similar fees and charges (other than Prepayment Charges) shall be retained by the Master Servicer only to the extent such amounts, fees or charges are received by the Master Servicer. The Master Servicer shall also be entitled pursuant to Section 3.05(a)(vi) to withdraw from the Collection Account, pursuant to Section 3.04(h) to withdraw from any Escrow Account and pursuant to Section 3.13(b) to withdraw from any REO Account, as additional servicing compensation, interest or other income earned on deposits therein, subject to Section 3.06. The Master Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including premiums for the insurance required by Section 3.08, Section 3.09 and Section 3.10, to the extent such premiums are not paid by the related Mortgagors or by a Sub-Servicer, servicing compensation of each Sub-Servicer, and to the extent provided in Section 8.05, the fees and expenses of the Trustee) and shall not be entitled to reimbursement therefor except as specifically provided herein.

SECTION 3.19. Statement as to Compliance.

The Master Servicer shall deliver to the Trustee, the NIMS Insurer, the Guarantor, the Depositor and each Rating Agency on or before March 15^th of each calendar year commencing in 2006, an Officers’ Certificate in a form similar to Exhibit M attached hereto agreeable to the parties hereto, stating, as to each signatory thereof, that (i) a review of the activities of the Master Servicer during the preceding calendar year and of performance under this Agreement has been made under such officers’ supervision and (ii) to the best of such officers’ knowledge, based on such review, the Master Servicer has fulfilled all of its obligations under this Agreement throughout such year, or, if there has been a default in the fulfillment of any such obligation, specifying each such default known to such officer and the nature and status thereof. Copies of any such statement shall be provided by the Trustee to any Certificateholder and to any Person identified to the Trustee as a prospective transferee of a Certificate, upon the request and at the expense of the requesting party, provided that such statement is delivered by the Master Servicer to the Trustee.

SECTION 3.20. Independent Public Accountants’ Servicing Report.

Not later than March 15^th of each calendar year commencing in 2006, the Master Servicer, at its expense, shall cause a nationally recognized firm of independent certified public accountants to furnish to the Master Servicer a report stating that (i) it has obtained a letter of representation regarding certain matters from the management of the Master Servicer which includes an assertion that the Master Servicer has complied with certain minimum residential mortgage loan servicing standards, identified in the Uniform Single Attestation Program for Mortgage Bankers established by the Mortgage Bankers Association of America, with respect to the servicing of residential mortgage loans during the most recently completed calendar year and (ii) on the basis of an examination conducted by such firm in accordance with standards established by the American Institute of Certified Public Accountants, such representation is fairly stated in all material respects, subject to such exceptions and other qualifications that may be appropriate. In rendering its report such firm may rely, as to matters relating to the direct servicing of residential mortgage loans by Sub-Servicers, upon comparable reports of firms of independent certified public accountants rendered on the basis of examinations conducted in accordance with the same standards (rendered within one year of such report) with respect to those Sub-Servicers. Immediately upon receipt of such report, the Master Servicer shall furnish a copy of such report to the Trustee, the NIMS Insurer, the Guarantor and each Rating Agency. Copies of such statement shall be provided by the Trustee to any Certificateholder upon request at the Master Servicer’s expense, provided that such statement is delivered by the Master Servicer to the Trustee. In the event such firm of independent certified public accountants 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 has not made 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 3.21. Access to Certain Documentation.

(a)        The Master Servicer shall provide to the Office of Thrift Supervision, the FDIC, and any other federal or state banking or insurance regulatory authority that may exercise authority over any Certificateholder or Certificate Owner, access to the documentation regarding the Mortgage Loans required by applicable laws and regulations. Such access shall be afforded without charge, but only upon reasonable request and during normal business hours at the offices of the Master Servicer designated by it. In addition, access to the documentation regarding the Mortgage Loans shall be provided to any Certificateholder or Certificate Owner, the Trustee, the NIMS Insurer, the Guarantor and to any Person identified to the Master Servicer as a prospective transferee of a Certificate, upon reasonable request during normal business hours at the offices of the Master Servicer designated by it at the expense of the Person requesting such access. In each case, access to any documentation regarding the Mortgage Loans may be conditioned upon the requesting party’s acknowledgment in writing of a confidentiality agreement reasonably satisfactory to the Master Servicer and the requesting party regarding any information that is required to remain confidential under the Gramm-Leach-Bliley Act of 1999. Nothing in this Section 3.21 shall limit the obligation of the Master Servicer to observe any applicable law prohibiting disclosure of information regarding the borrowers and the failure of the Master Servicer to provide access as provided in this Section 3.21 as a result of such obligation shall not constitute a breach of this Section 3.21.

(b)        For a period of two years from the Closing Date, the Guarantor may contact the Depositor or the Seller to confirm that the Seller continues to actively engage in a program to originate mortgage loans to low-income families and to obtain other non-proprietary information about the Seller’s activities that may assist the Guarantor in completing its own regulatory requirements during normal business hours and subject to reimbursement for expenses. The Depositor shall use reasonable efforts to provide such information to the Guarantor.

SECTION 3.22.	[Reserved].
SECTION 3.23.	Advance Facility.

(a)        The Master Servicer and/or the Trustee on behalf of the Trust Fund, in either case, with the consent of the Guarantor, the NIMS Insurer and the Master Servicer in the case of the Trustee, is hereby authorized to enter into a facility (an “Advance Facility”) with any Person (an “Advancing Person”) (1) under which the Master Servicer sells, assigns or pledges to the Advancing person the Master Servicer’s rights under this Agreement to be reimbursed for any Advances and/or Servicing Advances or (2) which provides that the Advancing Person may fund Advances and/or Servicing Advances to the Trust Fund under this Agreement, although no such facility shall reduce or otherwise affect the Master Servicer’s obligation to fund such Advances and/or Servicing Advances. If the Master Servicer enters into such an Advance Facility pursuant to this Section 3.23, upon reasonable request of the Advancing Person, the Trustee shall execute a letter of acknowledgment, confirming its receipt of notice of the existence of such Advance Facility. To the extent that an Advancing Person funds any Advance or any Servicing Advance or is assigned the right to be reimbursed for any Advance or Servicing Advance and provides the Trustee with notice acknowledged by the Master Servicer that such

Advancing Person is entitled to reimbursement directly from the Trustee pursuant to the terms of the Advance Facility, such Advancing Person shall be entitled to receive reimbursement pursuant to this Agreement for such amount to the extent provided in Section 3.23(b). Such notice from the Advancing Person must specify the amount of the reimbursement, the Section of this Agreement that permits the applicable Advance or Servicing Advance to be reimbursed and the section(s) of the Advance Facility that entitle the Advancing Person to request reimbursement from the Trustee, rather than the Master Servicer, and include the Master Servicer’s acknowledgment thereto or proof of an Event of Default under the Advance Facility. The Trustee shall have no duty or liability with respect to any calculation of any reimbursement to be paid to an Advancing Person and shall be entitled to rely without independent investigation on the Advancing Person’s notice provided pursuant to this Section 3.23. 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 Sub-Servicer pursuant to Section 6.06 hereof and shall not be deemed to be a Sub-Servicer under this Agreement. If the terms of a facility proposed to be entered into with an Advancing Person by the Trust Fund would not materially and adversely affect the interests of any Certificateholder, then the NIMS Insurer shall not withhold its consent to the Trust Fund’s entering such facility.

(b)        If, pursuant to the terms of the Advance Facility, an Advancing Person is entitled to reimbursement directly from the Trustee, then the Master Servicer shall not reimburse itself therefor under Section 3.05(a)(ii), Section 3.05(a)(iii) or Section 3.05(a)(v) prior to the remittance to the Trust Fund, but instead the Master Servicer shall include such amounts in the applicable remittance to the Trustee made pursuant to Section 3.04(g) to the extent of amounts on deposit in the Collection Account on the related Master Servicer Remittance Date. The Trustee is hereby authorized to pay to the Advancing Person reimbursements for Advances and Servicing Advances from the Distribution Account, to the extent permitted under the terms of the Advance Facility, to the same extent the Master Servicer would have been permitted to reimburse itself for such Advances and/or Servicing Advances in accordance with Section 3.05(a)(ii), Section 3.05(a)(iii) or Section 3.05(a)(v), as the case may be, had the Master Servicer itself funded such Advance or Servicing Advance. The Trustee is hereby authorized to pay directly to the Advancing Person such portion of the Servicing Fee as the parties to any Advance Facility agree to in writing delivered to the Trustee. An Advance Facility may provide that the Master Servicer will otherwise cause the remittance of Advance and/or Servicing Advance reimbursement amounts to the Advancing Person, in which case the foregoing sentences in this Section 3.23(b) shall not apply.

(c)        All Advances and Servicing Advances made pursuant to the terms of this Agreement shall be deemed made and shall be reimbursed on a “first in first out” (FIFO) basis.

(d)        In the event the Master Servicer is terminated pursuant to Section 7.01, the Advancing Person shall succeed to the terminated Master Servicer’s right of reimbursement set forth in Section 7.02(c) to the extent of such Advancing Person’s financing of or receipt of assignment or pledge of the right to be reimbursed for Advances or Servicing Advances hereunder then remaining unreimbursed.

(e)        None of the Trust Fund, any party to this Agreement or any other Person shall have any right or claim (including without limitation any right of offset or recoupment) to

any amounts allocable under this Agreement to the reimbursement of Advances or Servicing Advances that have been assigned, conveyed or pledged to an Advancing Person, or that relate to Advances or Servicing Advances that were funded by an Advancing Person.

(f)         Any amendment to this Section 3.23 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 3.23, including amendments to add provisions relating to a successor master servicer, may be entered into by the Trustee and the Master Servicer without the consent of any Certificateholder but with the consent of the Guarantor and the NIMS Insurer and written confirmation from each Rating Agency that the amendment shall not result in the reduction or withdrawal of the then-current ratings of any outstanding Class of Certificates or any other notes secured by collateral which includes all or a portion of the Class CE Certificates, the Class P Certificates and/or the Residual Certificates, notwithstanding anything to the contrary in this Agreement.

SECTION 3.24 Pool Policy; Claims Under the Pool Policy

(c)        The Master Servicer shall, on behalf of the Trustee, prepare and file on a timely basis with the Pool Insurer, with a copy to the Trustee, all claims which may be made under the Pool Policy with respect to the Covered Mortgage Loans. Consistent with all rights and obligations hereunder, the Master Servicer shall take all actions required under the Pool Policy as a condition to the payment of any such claim. Within ten (10) days after the Master Servicer receives notice or otherwise becomes aware that:

(i) A Borrower is Three (3) Months in Default, or;

(ii)         proceedings to acquire title to a Borrower’s property have been commenced,

whichever event occurs first, notice thereof shall be given to the Pool Insurer by the Master Servicer upon the form furnished by the Pool Insurer, provided, however, that failure of the Pool Insurer to furnish forms shall not relieve the Master Servicer of the obligation to give notice in any reasonable form within the required time. Thereafter, the Master Servicer shall report monthly to the Pool Insurer in summary form the status of the Borrower’s account, until a claim is submitted to the Pool Insurer or until such Borrower is less than Three (3) Months in Default. Any amount received from the Pool Insurer with respect to any such Covered Mortgage Loan shall be deposited by the Master Servicer into the Collection Account in accordance with Section 3.04(b).

(ii)         no interest shall accrue on such Certificates from and after the end of the related Interest Accrual Period.

Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held in trust by the Trustee and credited to the account of the appropriate non-tendering Holder or Holders. If any Certificates as to which

notice has been given pursuant to this Section 4.01(f) shall not have been surrendered for cancellation within six months after the time specified in such notice, the Trustee shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Trustee shall, directly or through an agent, mail a final notice to remaining non-tendering Certificateholders concerning surrender of their Certificates but shall continue to hold any remaining funds for the benefit of non-tendering Certificateholders. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in such trust fund. If within one year after the final notice any such Certificates shall not have been surrendered for cancellation, the Trustee shall pay to the Underwriters all remaining amounts, and all rights of non-tendering Certificateholders in or to such amounts shall thereupon cease. No interest shall accrue or be payable to any Certificateholder on any amount held in trust by the Trustee as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 4.01(f).

(g)        Notwithstanding anything to the contrary herein, (i) in no event shall the Certificate Principal Balance of a Class A Certificate or a Mezzanine Certificate be reduced more than once in respect of any particular amount both (a) allocated to such Certificate in respect of Realized Losses pursuant to Section 4.04 and (b) distributed to the Holder of such Certificate in reduction of the Certificate Principal Balance thereof pursuant to this Section 4.01 from Net Monthly Excess Cashflow and (ii) in no event shall the Uncertificated Balance of a REMIC Regular Interest be reduced more than once in respect of any particular amount both (a) allocated to such REMIC Regular Interest in respect of Realized Losses pursuant to Section 4.04 and (b) distributed on such REMIC Regular Interest in reduction of the Uncertificated Balance thereof pursuant to this Section 4.01.

(h)        It is the intention of all of the parties hereto that the Class CE Certificates receive all principal and interest received by the Trust on the Mortgage Loans that is not otherwise distributable to any other Class of Regular Certificates or REMIC Regular Interests. If the Trustee determines that the Residual Certificates are entitled to any distributions, the Trustee, prior to any such distribution to any Residual Certificate, shall notify the Depositor of such impending distribution. Upon such notification, the Depositor will request an amendment to the Pooling and Servicing Agreement to revise such mistake in the distribution provisions. The Residual Certificate Holders, by their acceptance of their Certificates, and the Master Servicer hereby agree and no further consent shall be necessary (other than the consent of the NIMS Insurer), notwithstanding anything to the contrary in Section 11.01 of the Pooling and Servicing Agreement.

Such statement may be in the form of the then current Fannie Mae Monthly Accounting Report for its Guaranteed Mortgage Pass-Through Program with appropriate additions and changes, and shall also include information as to the aggregate of the outstanding Stated Principal Balances of all of the Mortgage Loans as of the last day of the calendar month immediately preceding such Distribution Date.

(b)        The amount of Advances to be made by the Master Servicer for any Distribution Date shall equal, subject to Section 4.03(d), the sum of (i) the aggregate amount of Monthly Payments (with each interest portion thereof net of the related Servicing Fee), due on the related Due Date in respect of the Mortgage Loans, which Monthly Payments were delinquent as of the close of business on the related Determination Date and (ii) with respect to each REO Property, which REO Property was acquired during or prior to the related Prepayment

Period and as to which such REO Property an REO Disposition did not occur during the related Prepayment Period, an amount equal to the excess, if any, of the Monthly Payments (with each interest portion thereof net of the related Servicing Fee) that would have been due on the related Due Date in respect of the related Mortgage Loans, over the net income from such REO Property transferred to the Distribution Account pursuant to Section 3.13 for distribution on such Distribution Date.

On or before 1:00 p.m. New York time on the Master Servicer Remittance Date, the Master Servicer shall remit in immediately available funds to the Trustee for deposit in the Distribution Account an amount equal to the aggregate amount of Advances, if any, to be made in respect of the Mortgage Loans and REO Properties for the related Distribution Date either (i) from its own funds or (ii) from the Collection Account, to the extent of funds held therein for future distribution (in which case, it shall cause to be made an appropriate entry in the records of the Collection Account that amounts held for future distribution have been, as permitted by this Section 4.03, used by the Master Servicer in discharge of any such Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the total amount of Advances to be made by the Master Servicer with respect to the Mortgage Loans and REO Properties. Any amounts held for future distribution used by the Master Servicer to make an Advance as permitted in the preceding sentence or withdrawn by the Master Servicer as permitted in Section 3.05(a)(vii) in reimbursement of Advances previously made shall be appropriately reflected in the Master Servicer’s records and replaced by the Master Servicer by deposit in the Collection Account on or before any future Master Servicer Remittance Date to the extent that the Available Funds for the related Distribution Date (determined without regard to Advances to be made on the Master Servicer Remittance Date) shall be less than the total amount that would be distributed to the Classes of Certificateholders pursuant to Section 4.01 on such Distribution Date if such amounts held for future distributions had not been so used to make Advances. The Trustee shall provide notice to the Master Servicer, the Guarantor and the NIMS Insurer by telecopy by the close of business on any Master Servicer Remittance Date in the event that the amount remitted by the Master Servicer to the Trustee on such date is less than the Advances required to be made by the Master Servicer for the related Distribution Date.

(c)        The obligation of the Master Servicer to make such Advances is mandatory, notwithstanding any other provision of this Agreement but subject to (d) below, and, with respect to any Mortgage Loan or REO Property, shall continue until a Final Recovery Determination in connection therewith or the removal thereof from REMIC I pursuant to any applicable provision of this Agreement, except as otherwise provided in this Section.

(d)        Notwithstanding anything herein to the contrary, no Advance or Servicing Advance shall be required to be made hereunder by the Master Servicer if such Advance or Servicing Advance would, if made, constitute a Nonrecoverable Advance or Nonrecoverable Servicing Advance. The determination by the Master Servicer that it has made a Nonrecoverable Advance or a Nonrecoverable Servicing Advance or that any proposed Advance or Servicing Advance, if made, would constitute a Nonrecoverable Advance or Nonrecoverable Servicing Advance, respectively, shall be evidenced by an Officers’ Certificate of the Master Servicer delivered to the Trustee, the Guarantor and the NIMS Insurer.

(e)        The Master Servicer shall deliver to the Trustee for deposit into the Distribution Account on or before 1:00 p.m. New York time on the Master Servicer Remittance Date from its own funds an amount (“Compensating Interest”) equal to the lesser of (i) the aggregate of the Prepayment Interest Shortfalls for the related Distribution Date resulting solely from Principal Prepayments during the related Prepayment Period and (ii) the amount of its aggregate Servicing Fee for the most recently ended calendar month. The Master Servicer shall not have the right to reimbursement for any amounts remitted to the Trustee in respect of Prepayment Interest Shortfalls. Such amounts so remitted shall be included in the Available Funds and distributed therewith on the next Distribution Date. The Master Servicer shall not be obligated to pay any amounts with respect to Relief Act Interest Shortfalls.

SECTION 4.04. Allocation of Realized Losses.

(a)        On or before each Determination Date, the Master Servicer shall determine as to each Mortgage Loan and REO Property: (i) the total amount of Realized Losses, if any, incurred in connection with any Final Recovery Determinations made during the related Prepayment Period; (ii) whether and the extent to which such Realized Losses constituted Bankruptcy Losses; and (iii) the respective portions of such Realized Losses allocable to interest and allocable to principal. On or before each Determination Date, the Master Servicer shall also determine as to each Mortgage Loan: (A) the total amount of Realized Losses, if any, incurred in connection with any Deficient Valuations made during the related Prepayment Period; and (B) the total amount of Realized Losses, if any, incurred in connection with Debt Service Reductions in respect of Monthly Payments due during the related Due Period. The information described in the two preceding sentences that is to be supplied by the Master Servicer shall be evidenced by an Officers’ Certificate delivered to the Trustee and the Guarantor by the Master Servicer on the Master Servicer Reporting Date immediately following the end of (x) in the case of Bankruptcy Losses allocable to interest, the Due Period during which any such Realized Loss was incurred, and (y) in the case of all other Realized Losses, the Prepayment Period during which any such Realized Loss was incurred.

(b)        All Realized Losses on the Mortgage Loans shall be allocated by the Trustee on each Distribution Date as follows: first, in reduction of interest accrued on and otherwise distributable to the Class CE Certificates to the extent of Net Monthly Excess Cashflow used to pay principal on the Class A Certificates and the Mezzanine Certificates under clause (i) of Section 4.01 hereof; second, in reduction of interest accrued on and otherwise distributable to the Class CE Certificates to the extent of Net Monthly Excess Cashflow available for distribution pursuant to clauses (ii) through (vi) of Section 4.01(a)(4) hereof; and third, in reduction of the Certificate Principal Balance of the Class CE Certificates (determined after taking into account all distributions made on the Certificates on such Distribution Date), until the Certificate Principal Balance thereof has been reduced to zero. If on any Distribution Date, after all distributions are made by the Trustee pursuant to Section 4.01 hereof, the aggregate Certificate Principal Balance of the Class A Certificates, the Mezzanine Certificates and the Class P Certificates exceeds the sum of the Stated Principal Balance of the Mortgage Loans as of the last day of the related Due Period (after taking into account prepayments during the related Prepayment Period), the amount of such excess shall be allocated: first, to the Class M-12 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; second, to the Class M-11 Certificates, until the Certificate Principal Balance thereof has been reduced to

zero; third, to the Class M-10 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fourth, to the Class M-9 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fifth, to the Class M-8 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; sixth, to the Class M-7 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; seventh, to the Class M-6 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; eighth, to the Class M-5 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; ninth, to the Class M-4 Certificates, until the Certificate Principal Balance thereof has been reduced to zero, tenth, to the Class M-3 Certificates, until the Certificate Principal Balance thereof has been reduced to zero, eleventh, to the Class M-2 Certificates, until the Certificate Principal Balance thereof has been reduced to zero and twelfth, to the Class M-1 Certificates, until the Certificate Principal Balance thereof has been reduced to zero. All Realized Losses to be allocated to the Certificate Principal Balances of all Classes on any Distribution Date shall be so allocated after the actual distributions to be made on such date as provided above.

Any such allocation to a Class of Mezzanine Certificates on any Distribution Date shall be made by reducing the Certificate Principal Balance thereof (after the actual distributions to be made on such Distribution Date pursuant to Section 4.01 hereof) by the amount so allocated; any allocation of Realized Losses to a Class CE Certificate shall be made by reducing the amount otherwise payable in respect thereof pursuant to Section 4.01(a)(4)(v). No allocations of any Realized Losses shall be made to the Certificate Principal Balances of the Class A Certificates or the Class P Certificates.

As used herein, 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. All Realized Losses and all other losses allocated to a Class of Certificates hereunder shall be allocated among the Certificates of such Class in proportion to the Percentage Interests evidenced thereby.

(c)        All Realized Losses on the Group I Loans shall be allocated on each Distribution Date first, to REMIC I Regular Interest I until the Uncertificated Balance of such REMIC I Regular Interest has been reduced to zero and second, to REMIC I Regular Interest I-1-A through REMIC I Regular Interest I-55-B, starting with the lowest numerical denomination until such REMIC I Regular Interest has been reduced to zero, provided that, for REMIC I Regular Interests with the same numerical denomination, such Realized Losses shall be allocated pro rata between such REMIC I Regular Interests. All Realized Losses on the Group II Loans shall be allocated on each Distribution Date first, to REMIC I Regular Interest II until the Uncertificated Balance of such REMIC I Regular Interest has been reduced to zero and second, to REMIC I Regular Interest II-1-A through REMIC I Regular Interest II-55-B, starting with the lowest numerical denomination until such REMIC I Regular Interest has been reduced to zero, provided that, for REMIC I Regular Interests with the same numerical denomination, such Realized Losses shall be allocated pro rata between such REMIC I Regular Interests.

(c) (i)    The REMIC II Marker Allocation Percentage of all Realized Losses on the Mortgage Loans shall be allocated by the Trustee on each Distribution Date to the following

REMIC II Regular Interests in the specified percentages, as follows: first, to Uncertificated Interest payable to the REMIC II Regular Interest II-LTAA and REMIC II Regular Interest II-LTZZ up to an aggregate amount equal to the REMIC II Interest Loss Allocation Amount, 98% and 2%, respectively; second, to the Uncertificated Balances of the REMIC II Regular Interest II-LTAA and REMIC II Regular Interest II-LTZZ up to an aggregate amount equal to the REMIC II Principal Loss Allocation Amount, 98% and 2%, respectively; third, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM12 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM12 has been reduced to zero, fourth, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM11 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM11 has been reduced to zero, fifth to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM10 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM10 has been reduced to zero; sixth, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM9 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM9 has been reduced to zero; seventh, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM8 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM8 has been reduced to zero; eighth, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM7 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM7 has been reduced to zero; ninth, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM6 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM6 has been reduced to zero; tenth, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM5 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM5 has been reduced to zero; eleventh, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM4 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM4 has been reduced to zero; twelfth, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM3 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM3 has been reduced to zero; thirteenth, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM2 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM2 has been reduced to zero; and fourteenth, to the Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM1 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC II Regular Interest II-LTM1 has been reduced to zero.

The REMIC II Sub WAC Allocation Percentage of all Realized Losses shall be applied after all distributions have been made on each Distribution Date first, so as to keep the Uncertificated Balance of each REMIC II Regular Interest ending with the designation “GRP”

equal to 0.01% of the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group; second, to each REMIC II Regular Interest ending with the designation “SUB,” so that the Uncertificated Balance of each such REMIC II Regular Interest is equal to 0.01% of the excess of (x) the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group over (y) the current Certificate Principal Balance of the Class A Certificate in the related Loan Group (except that if any such excess is a larger number than in the preceding distribution period, the least amount of Realized Losses shall be applied to such REMIC II Regular Interests such that the REMIC II Subordinated Balance Ratio is maintained); and third, any remaining Realized Losses shall be allocated to REMIC II Regular Interest II-LTXX.

SECTION 4.05. Compliance with Withholding Requirements.

Notwithstanding any other provision of this Agreement, the Trustee shall comply with all federal withholding requirements respecting payments to Certificateholders of interest or original issue discount that the Trustee reasonably believes are applicable under the Code. The consent of Certificateholders shall not be required for such withholding. In the event the Trustee does withhold any amount from interest or original issue discount payments or advances thereof to any Certificateholder pursuant to federal withholding requirements, the Trustee shall indicate the amount withheld to such Certificateholders.

SECTION 4.06. Commission Reporting.

(a)        The Trustee shall reasonably cooperate with the Depositor in connection with the Trust’s satisfying the reporting requirements under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Trustee shall prepare on behalf of the Trust any Forms 8-K and 10-K customary for similar securities as required by the Exchange Act and the Rules and Regulations of the Commission thereunder, and the Depositor shall sign (or shall cause another entity acceptable to the Commission to sign) and the Trustee shall file (via the Commission’s Electronic Data Gathering and Retrieval System) such forms on behalf of the Depositor (or such other entity). The Depositor hereby grants to the Trustee a limited power of attorney to execute any Form 8-K and file each such document on behalf of the Depositor. Such power of attorney shall continue until the earlier of (i) receipt by the Trustee from the Depositor of written termination of such power of attorney and (ii) the termination of the Trust. Notwithstanding anything herein to the contrary, the Depositor, and not the Trustee, shall be responsible for executing each Form 10-K filed on behalf of the Trust.

(b)        Each Form 8-K shall be filed by the Trustee within 15 days after each Distribution Date, with a copy of the statement to the Certificateholders for such Distribution Date as an exhibit thereto. Prior to March 30^th of each year (or such earlier date as may be required by the Exchange Act and the Rules and Regulations of the Commission), the Trustee shall file a Form 10-K, in substance as required by applicable law or applicable Commission staff’s interpretations. Such Form 10-K shall include as exhibits the Master Servicer’s annual statement of compliance described under Section 3.19 and the accountant’s report described under Section 3.20, in each case to the extent they have been timely delivered to the Trustee. If they are not so timely delivered, the Trustee shall file an amended Form 10-K including such documents as exhibits reasonably promptly after they are delivered to the Trustee. The Trustee shall have no liability with respect to any failure to properly prepare or file such periodic reports

resulting from or relating to the Trustee’s inability or failure to obtain any information not resulting from its own negligence or willful misconduct. The Form 10-K shall also include a certification in the form attached hereto as Exhibit J-1 (the “Certification”), which shall be signed by the senior officer of the Depositor in charge of securitization.

(c)        In addition, the Trustee shall sign a certification (in the form attached hereto as Exhibit J-2) for the benefit of the Depositor and its officers, directors and Affiliates regarding certain aspects of items 1 through 3 of the Certification (provided, however, that the Trustee shall not undertake an analysis of the accountant’s report attached as an exhibit to the Form 10-K). The Trustee’s certification shall be delivered to the Depositor by no later than March 18^th of each year (or if such day is not a Business Day, the immediately preceding Business Day) and the Depositor shall deliver the Certification to the Trustee for filing no later than March 20^th of each year (or if such day is not a Business Day, the immediately preceding Business Day).

In addition, the Trustee shall indemnify and hold harmless the Depositor and its officers, directors and Affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon a breach of the Trustee’s obligations under this Section 4.06 or the Trustee’s negligence, bad faith or willful misconduct in connection therewith. The Depositor shall indemnify and hold harmless the Trustee and its officers, directors and Affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon a breach of the Depositor’s obligations under this Section 4.06 or the Depositor’s negligence, bad faith or willful misconduct in connection therewith. If the indemnification provided for herein is unavailable or insufficient to hold harmless the Depositor or the Trustee, as applicable, then the other party, in connection with a breach of its respective obligations under this Section 4.06 or its respective negligence, bad faith or willful misconduct in connection therewith, agrees that it shall contribute to the amount paid or payable by the other party as a result of the losses, claims, damages or liabilities of the other party in such proportion as is appropriate to reflect the relative fault of the Depositor on the one hand and the Trustee on the other.

(d)        Upon any filing with the Commission, the Trustee shall promptly deliver to the Depositor a copy of any executed report, statement or information.

(e)        Prior to January 30^th of the first year in which the Trustee is able to do so under applicable law, the Trustee shall file a Form 15 Suspension Notification with respect to the Trust.

(f)         To the extent that, following the Closing Date, the Depositor certifies that reports and certifications differing from those required under this Section 4.06 comply with the reporting requirements under the Exchange Act, the Trustee hereby agrees that it shall reasonably cooperate to amend the provisions of this Section 4.06 (in accordance with Section 11.01) in order to comply with such amended reporting requirements and such amendment of this Section 4.06. Any such amendment may result in the reduction of the reports filed by the Depositor under the Exchange Act. Notwithstanding the foregoing, the Trustee shall not be

obligated to enter into any amendment pursuant to this Section that adversely affects its obligations and immunities under this Agreement.

SECTION 4.07.	[Reserved].
SECTION 4.08.	[Reserved].
SECTION 4.09.		The Guaranty.

On each Distribution Date following receipt (i) of a statement (in the form set forth in Section 4.02) that indicates a Guarantor Deficiency Amount for such Distribution Date and (ii) the Notice of Claim, the Guarantor shall distribute a Guarantor Payment, in an aggregate amount equal to the Guarantor Deficiency Amount for such Distribution Date directly to the Holders of the Guaranteed Certificates, without first depositing such amount in the Distribution Account, as follows: (i) the Guaranteed Interest Distribution Amount shall be distributed as interest with respect to the Guaranteed Certificates as provided in Section 4.01; and (ii) the Guaranteed Principal Distribution Amount shall be distributed as principal with respect to the Guaranteed Certificates as provided in Section 4.01.

SECTION 4.10. Swap Account

(a)        No later than the Closing Date, the Trustee shall establish and maintain with itself, as agent for the Trustee, a separate, segregated trust account titled, “Swap Account, Deutsche Bank National Trust Company, as Trustee, in trust for the Swap Provider and the registered holders of Ameriquest Mortgage Securities Inc., Asset-Backed Pass-Through Certificates, Series 2005-R7.” Such account shall be an Eligible Account and amounts therein shall be held uninvested.

(b)        On each Distribution Date, prior to any distribution to any Certificate, the Trustee shall deposit into the Swap Account pursuant to 3.05(c)(i): (i) the amount of any Net Swap Payment or Swap Termination Payment owed to the Swap Provider (after taking into account any upfront payment received from the counterparty to a replacement swap agreement) from funds collected and received with respect to the Mortgage Loans prior to the determination of Available Funds and (ii) amounts received by the Trustee from the Swap Administrator, for distribution in accordance with subsection (d) below, pursuant to the Swap Administration Agreement, dated as of the Closing Date (the “Swap Administration Agreement”), among Deutsche Bank National Trust Company in its capacity as Trustee, Deutsche Bank National Trust Company in its capacity as Swap Administrator and Ameriquest Mortgage Company. For federal income tax purposes, any amounts paid to the Swap Provider on each Distribution Date shall first be deemed paid to the Swap Provider in respect of the Class SWAP-IO Interest to the extent of the amount distributable on such Class SWAP-IO Interest on such Distribution Date, and any remaining amount shall be deemed paid to the Swap Provider in respect of a Class IO Distribution Amount (as defined below).

If the Trustee fails to pay any Net Swap Payment owed to the Swap Provider and such failure to pay is not related to insufficient funds in the Distribution Account and such failure to pay would, pursuant to the terms of the Interest Rate Swap Agreement, cause a Swap Termination Payment to be owed to the Swap Provider, the NIMS Insurer may, on behalf of the

Trustee and after consultation with the Trustee, pay such Net Swap Payment owed to the Swap Provider. The NIMS Insurer shall be reimbursed by the Trustee pursuant to Section 3.05(c).

(c)        For federal income tax purposes, the Swap Account shall be owned by the majority Holder of the Class CE Certificates.

(d)        The Trustee shall treat the Holders of Certificates (other than the Class P, Class CE and Class R Certificates) as having entered into a notional principal contract with respect to the Holders of the Class CE Certificates. Pursuant to each such notional principal contract, all Holders of Certificates (other than the Class P, Class CE and Class R Certificates) shall be treated as having agreed to pay, on each Distribution Date, to the Holder of the Class CE Certificates an aggregate amount equal to the excess, if any, of (i) the amount payable on such Distribution Date on the REMIC III Regular Interest corresponding to such Class of Certificates over (ii) the amount payable on such Class of Certificates on such Distribution Date (such excess, a “Class IO Distribution Amount”). A Class IO Distribution Amount payable from interest collections shall be allocated pro rata among such Certificates based on the excess of (a) the amount of interest otherwise payable to such Certificates over (ii) the amount of interest payable to such Certificates at a per annum rate equal to the Net WAC Pass-Through Rate, and a Class IO Distribution Amount payable from principal collections shall be allocated to the most subordinate Class of Certificates with an outstanding principal balance to the extent of such balance. In addition, pursuant to such notional principal contract, the Holder of the Class CE Certificates shall be treated as having agreed to pay Net WAC Rate Carryover Amounts to the Holders of the Certificates (other than the Class CE, Class P and Class R Certificates) in accordance with the terms of this Agreement. Any payments to the Certificates from amounts deemed received in respect of this notional principal contract shall not be payments with respect to a Regular Interest in a REMIC within the meaning of Code Section 860G(a)(1). However, any payment from the Certificates (other than the Class CE, Class P and Class R Certificates) of a Class IO Distribution Amount shall be treated for tax purposes as having been received by the Holders of such Certificates in respect of their interests in REMIC IV and as having been paid by such Holders to the Swap Administrator pursuant to the notional principal contract. Thus, each Certificate (other than the Class P and Class R Certificates) shall be treated as representing not only ownership of Regular Interests in REMIC IV, but also ownership of an interest in, and obligations with respect to, a notional principal contract.

SECTION 4.11. Net WAC Rate Carryover Reserve Account.

(a)        No later than the Closing Date, the Trustee shall establish and maintain with itself, as agent for the Trustee, a separate, segregated trust account titled, “Net WAC Rate Carryover Reserve Account, Deutsche Bank National Trust Company, as Trustee, in trust for the registered Holders of Ameriquest Mortgage Securities Inc., Asset-Backed Pass-Through Certificates, Series 2005-R7.” The Trustee shall deposit into the Net WAC Rate Carryover Reserve Account any payments received by it pursuant to Section 4.01(a)(4)(iv).

(b)        On each Distribution Date as to which there is a Net WAC Rate Carryover Amount payable to the Adjustable-Rate Certificates, the Trustee has been directed by the Class CE Certificateholders to, and therefore shall, deposit into the Net WAC Rate Carryover Reserve Account the amount of such Net WAC Rate Carryover Amount rather than distributing such

amounts to the Class CE Certificateholders. On each such Distribution Date, the Trustee shall hold all such amounts for the benefit of the Holders of the Adjustable-Rate Certificates, and shall distribute such amounts to the Holders of the Adjustable-Rate Certificates in the amounts and priorities set forth in Section 4.01(a).

(c)        For federal and state income tax purposes, the Class CE Certificateholders shall be deemed to be the owners of the Net WAC Rate Carryover Reserve Account and all amounts deposited into the Net WAC Rate Carryover Reserve Account shall be treated as amounts distributed by REMIC IV to the Holders of the Class CE Certificates. Upon the termination of the Trust Fund, or the payment in full of the Adjustable-Rate Certificates, all amounts remaining on deposit in the Net WAC Rate Carryover Reserve Account shall be released by the Trust and distributed to the Class CE Certificateholders or their designees. The Net WAC Rate Carryover Reserve Account shall be part of the Trust but not part of any REMIC and any payments to the Holders of the Adjustable-Rate Certificates of Net WAC Rate Carryover Amounts shall not be payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860(G)(a)(1).

(d)        By accepting a Class CE Certificate, each Class CE Certificateholder hereby agrees to direct the Trustee, and the Trustee hereby is directed, to deposit into the Net WAC Rate Carryover Reserve Account the amounts described above on each Distribution Date as to which there is any Net WAC Rate Carryover Amount rather than distributing such amounts to the Class CE Certificateholders. By accepting a Class CE Certificate, each Class CE Certificateholder further agrees that such direction is given for good and valuable consideration, the receipt and sufficiency of which is acknowledged by such acceptance.

(e)        At the written direction of the Holders of a majority in Percentage Interest in the Class CE Certificates, the Trustee shall direct any depository institution maintaining the Net WAC Rate Carryover Reserve Account to invest the funds in such account in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Trustee or an Affiliate manages or advises such investment, and (ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Trustee or an Affiliate manages or advises such investment. If no investment direction of the Holders of a majority in Percentage Interest in the Class CE Certificates with respect to the Net WAC Rate Carryover Reserve Account is received by the Trustee, the Trustee shall invest the funds in the Deutsche Bank Institutional Cash Management Fund 541 so long as it is a Permitted Investment. Interest earned on such investment shall be deposited into the Net WAC Rate Carryover Reserve Account.

(f)         For federal income tax return and information reporting, the value assigned to the right of the Holders of the Class A and Mezzanine Certificates to receive payments from the Net WAC Rate Carryover Reserve Account in respect of any Net WAC Rate Carryover Amount shall be de minimis.

SECTION 4.12. Tax Treatment of Swap Payments and Swap Termination Payments.

For federal income tax purposes, each holder of a Class A or Mezzanine Certificate is deemed to own an undivided beneficial ownership interest in a REMIC regular interest and the right to receive payments from either the Net WAC Rate Carryover Reserve Account or the Swap Account in respect of the Net WAC Rate Carryover Amount or the obligation to make payments to the Swap Account. For federal income tax purposes, the Trustee will account for payments to each Class A and Mezzanine Certificates as follows: each Class A and Class M Certificate will be treated as receiving their entire payment from REMIC III (regardless of any Swap Termination Payment or obligation under the Interest Rate Swap Agreement) and subsequently paying their portion of any Swap Termination Payment in respect of each such Class’ obligation under the Interest Rate Swap Agreement. In the event that any such Class is resecuritized in a REMIC, the obligation under the Interest Rate Swap Agreement to pay any such Swap Termination Payment (or any shortfall in Swap Provider Fee), will be made by one or more of the REMIC Regular Interests issued by the resecuritization REMIC subsequent to such REMIC Regular Interest receiving its full payment from any such Class A or Mezzanine Certificate. Resecuritization of any Class A or Mezzanine Certificate in a REMIC will be permissible only if the Trustee hereunder is the trustee in such resecuritization.

The REMIC regular interest corresponding to a Class A or Mezzanine Certificate will be entitled to receive interest and principal payments at the times and in the amounts equal to those made on the certificate to which it corresponds, except that (i) the maximum interest rate of that REMIC regular interest will equal the Net WAC Pass-Through Rate computed for this purpose by limiting the Base Calculation Amount of the Interest Rate Swap Agreement to the aggregate principal balance of the Mortgage Loans and (ii) any Swap Termination Payment will be treated as being payable solely from Net Monthly Excess Cashflow. As a result of the foregoing, the amount of distributions and taxable income on the REMIC regular interest corresponding to a Class A or Mezzanine Certificate may exceed the actual amount of distributions on the Class A or Mezzanine Certificate.

ARTICLE V

THE CERTIFICATES

SECTION 5.01. The Certificates.

(a)        The Certificates in the aggregate shall represent the entire beneficial ownership interest in the Mortgage Loans and all other assets included in REMIC I. At the Closing Date, the aggregate Certificate Principal Balance of the Certificates shall equal the aggregate Stated Principal Balance of the Mortgage Loans.

The Certificates shall be substantially in the forms annexed hereto as Exhibits A-1A through A-R. The Certificates of each Class shall be issuable in registered form only, in denominations of authorized Percentage Interests as described in the definition thereof. Each Certificate shall share ratably in all rights of the related Class.

Upon original issue, the Certificates shall be executed and delivered by the Trustee and the Trustee shall cause the Certificates to be authenticated by the Certificate Registrar to or upon the order of the Depositor. The Certificates shall be executed and attested by manual or facsimile signature on behalf of the Trustee by an authorized signatory. 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 Certificates 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 herein executed by the Certificate Registrar by manual signature, and such certificate of authentication 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 and the Mezzanine Certificates shall initially be issued as one or more Certificates held by the Book-Entry Custodian or, if appointed to hold such Certificates as provided below, the Depository, and 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 such Certificates through the book-entry facilities of the Depository and, except as provided below, shall not be entitled to definitive, fully registered Certificates (“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 only transfer the Ownership Interests 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 is hereby initially appointed as the Book-Entry Custodian and hereby agrees to act as such in accordance herewith and in accordance with the agreement that it has with the Depository authorizing it to act as such. The Book-Entry Custodian may, and if it is

no longer qualified to act as such, the Book-Entry Custodian shall, appoint, by a written instrument delivered to the Depositor, the Master Servicer, the Trustee (if the Trustee is not the Book-Entry Custodian) and any other transfer agent (including the Depository or any successor Depository), to act as Book-Entry Custodian under such conditions as the predecessor Book-Entry Custodian and the Depository or any successor Depository may prescribe, provided that the predecessor Book-Entry Custodian shall not be relieved of any of its duties or responsibilities by reason of any such appointment of other than the Depository. If the Trustee resigns or is removed in accordance with the terms hereof, if it so elects, the Depository shall immediately succeed to its predecessor’s duties as Book-Entry Custodian. The Depositor shall have the right to inspect, and to obtain copies of, any Certificates held as Book-Entry Certificates by the Book-Entry Custodian.

The Trustee, the Master Servicer, the Guarantor and the Depositor may for all purposes (including the making of payments due on the Book-Entry Certificates) deal with the Depository as the authorized representative of the Certificate Owners with respect to the Book-Entry Certificates for the purposes of exercising the rights of Certificateholders hereunder. The rights of Certificate Owners with respect to the 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 the 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) after the occurrence of a Master Servicer Event of Default, Certificate Owners representing in the aggregate not less than 51% of the Ownership Interests of the Book-Entry Certificates advise the Trustee through the Depository, in writing, that the continuation of a book-entry system through the Depository is no longer in the best interests of the Certificate Owners, 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 Book-Entry Custodian or the Depository, as applicable, accompanied by registration instructions from the Depository for registration of transfer, the Trustee shall issue the Definitive Certificates. Such Definitive Certificates shall be issued in minimum denominations of $25,000 ($1,000 in the case of the Group I Certificates and $50,000 in the case of the Private Mezzanine Certificates), except that any beneficial ownership that was represented by a Book-Entry Certificate in an amount less than $25,000 immediately prior to the issuance of a Definitive Certificate shall be issued in a minimum denomination equal to the amount represented by such Book-Entry Certificate. None of the Depositor, the Master Servicer or the Trustee shall be liable for any delay in the delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Trustee, to the extent

applicable with respect to such Definitive Certificates, and the Trustee shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder.

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 for the Certificates 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 shall initially serve as Certificate Registrar for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided. The Certificate Registrar may appoint, by a written instrument delivered to the Master Servicer and the Depositor, any other bank or trust company to act as Certificate Registrar under such conditions as the predecessor Certificate Registrar may prescribe, provided that the predecessor Certificate Registrar shall not be relieved of any of its duties or responsibilities hereunder by reason of such appointment. If the Trustee shall at any time not be the Certificate Registrar, the Trustee shall have and maintain the right to inspect the Certificate Register or to obtain a copy thereof at all reasonable times, and to rely conclusively upon a certificate of the Certificate Registrar as to the information set forth in the Certificate Register.

(b)        No transfer of any Private Mezzanine Certificate, Class CE Certificate, Class P Certificate or Residual Certificate (the “Private Certificates”) shall be made unless that transfer is made pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “1933 Act”), and an effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification. In the event that such a transfer of a Private Certificate is to be made without registration or qualification (other than in connection with (i) the initial transfer of any such Certificate by the Depositor, (ii) the transfer of any such Class CE, Class P or Residual Certificate to the issuer under the Indenture or the indenture trustee under the Indenture or (iii) a transfer of any such Class CE, Class P or Residual Certificate from the issuer under the Indenture or the indenture trustee under the Indenture to the Depositor or an Affiliate of the Depositor), the Trustee and the Certificate Registrar shall each require receipt of: (i) if such transfer is purportedly being made in reliance upon Rule 144A under the 1933 Act, written certifications from the Certificateholder desiring to effect the transfer and from such Certificateholder’s prospective transferee, substantially in the forms attached hereto as Exhibit F-1; and (ii) in all other cases, an Opinion of Counsel satisfactory to it that such transfer may be made without such registration (which Opinion of Counsel shall not be an expense of the Depositor, the Trustee, the Master Servicer, or the Trust Fund), together with copies of the written certification(s) of the Certificateholder desiring to effect the transfer and/or such Certificateholder’s prospective transferee upon which such Opinion of Counsel is based, if any. None of the Depositor, the Certificate Registrar or the Trustee is obligated to register or qualify the Private Certificates under the 1933 Act or any other securities laws or to take any action not otherwise required under this Agreement to permit the transfer of such Certificates without registration or qualification. If a transfer of an Ownership Interest in the Private Mezzanine Certificates is to be made without registration under the 1933 Act (other than in connection with the initial transfer of any such Certificate by the Depositor to an affiliate of the Depositor), then the Certificate Registrar shall refuse to register such transfer unless it receives (and upon receipt, may conclusively rely upon) a certificate from the

Certificateholder desiring to effect such transfer and a certificate from such Certificateholder’s prospective transferee (which in the case of the Book Entry Certificates, the Certificateholder and the Certificateholder’s prospective transferee shall be deemed to have represented such certification), to the effect that, among other things, the transfer is being made to a qualified institutional buyer as defined in Rule 144A under the Securities Act in accordance with Rule 144A. Any Certificateholder desiring to effect the transfer of a Private Mezzanine Certificate, Class CE Certificate, Class P Certificate or Residual Certificate shall, and does hereby agree to, indemnify the Trustee, the Depositor, the Certificate Registrar and the Master Servicer 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.

Notwithstanding the foregoing, no certification or Opinion of Counsel described in this Section 5.02(b) shall be required in connection with the transfer, on the Closing Date, of any Residual Certificate by the Depositor to an “accredited investor” within the meaning of Rule 501(d) of the 1933 Act.

(c)        No transfer of a Certificate or any interest therein shall be made to any Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person acquiring such Certificates with “Plan Assets” of a Plan within the meaning of the Department of Labor regulation promulgated at 29 C.F.R. § 2510.3-101 (“Plan Assets”), as certified by such transferee in the form of Exhibit G, (or, in the case of a Book Entry Certificate, such transferee shall be deemed to represent that it is not a Plan or acquiring with Plan Assets), unless the Trustee is provided with an Opinion of Counsel for the benefit of the Trust Fund, the Depositor, the Trustee and the Master Servicer and on which they may rely, which shall be to the effect that the purchase and holding of such Certificates is permissible under applicable law, shall not constitute or result in any non-exempt prohibited transaction under ERISA or Section 4975 of the Code and shall not subject the Depositor, the Master Servicer, the Trustee or the Trust Fund 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 Depositor, the Master Servicer, the NIMS Insurer, the Guarantor, the Trustee or the Trust Fund. Neither an Opinion of Counsel nor any certification shall be required in connection with (i) the initial transfer of any such Certificate by the Depositor to an affiliate of the Depositor, (ii) the transfer of any such Class CE, Class P or Residual Certificate to the issuer under the Indenture or the indenture trustee under the Indenture or (iii) a transfer of any such Class CE, Class P or Residual Certificate from the issuer under the Indenture or the indenture trustee under the Indenture to the Depositor or an Affiliate of the Depositor (in which case, the Depositor or any Affiliate thereof shall have deemed to have represented that it is not purchasing with Plan Assets) and the Trustee shall be entitled to conclusively rely upon a representation (which, upon the request of the Trustee, shall be a written representation) from the Depositor of the status of such transferee as an affiliate of the Depositor.

If any Certificate or any interest therein is acquired or held in violation of the provisions of the preceding paragraphs, the next preceding permitted beneficial owner shall be treated as the beneficial owner of that Certificate retroactive to the date of transfer to the purported beneficial owner. Any purported beneficial owner whose acquisition or holding of any such Certificate or interest therein was effected in violation of the provisions of the preceding

paragraph shall indemnify and hold harmless the Depositor, the Master Servicer, the Trustee, the NIMS Insurer, the Guarantor and the Trust Fund from and against any and all liabilities, claims, costs or expenses incurred by those parties as a result of that acquisition or holding.

(d)        (i) Each Person who has or who acquires any Ownership Interest in a Residual 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 Certificate Registrar 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 Residual Certificate are expressly subject to the following provisions:

(A) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Certificate Registrar 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 Residual Certificate, the Certificate Registrar shall require delivery to it and shall not register the Transfer of any Residual Certificate until its receipt of an affidavit and agreement (a “Transfer Affidavit and Agreement”), in the form attached hereto as Exhibit F-2 from the proposed Transferee, in form and substance satisfactory to the Certificate Registrar, representing and warranting, among other things, that such Transferee is a Permitted Transferee, that it is not acquiring its Ownership Interest in the Residual Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person that is not a Permitted Transferee, that for so long as it retains its Ownership Interest in a Residual Certificate, it shall endeavor to remain a Permitted Transferee, and that it has reviewed the provisions of this Section 5.02(d) and agrees to be bound by them.

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

(D) Each Person holding or acquiring any Ownership Interest in a Residual 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 Residual Certificate and (y) not to transfer its Ownership Interest unless it provides a Transferor Affidavit (in the form attached hereto as Exhibit F-2), to the Certificate Registrar stating that, among other things, it has no actual knowledge that such other Person is not a Permitted Transferee.

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

The Certificate Registrar shall register the Transfer of any Residual Certificate only if it shall have received the Transfer Affidavit and Agreement and all of such other documents as shall have been reasonably required by the Certificate Registrar as a condition to such registration. In addition, no Transfer of a Residual Certificate shall be made unless the Certificate Registrar shall have received a representation letter from the Transferee of such Certificate to the effect that such Transferee is a Permitted Transferee.

(iii)(A) If any purported Transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.02(d), then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights as Holder thereof retroactive to the date of registration of such Transfer of such Residual Certificate. The Certificate Registrar shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by this Section 5.02(d) 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 Residual Certificate in violation of the restrictions in this Section 5.02(d) and to the extent that the retroactive restoration of the rights of the Holder of such Residual Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Certificate Registrar shall have the right, without notice to the Holder or any prior Holder of such Residual Certificate, to sell such Residual Certificate to a purchaser selected by the Certificate Registrar on such terms as the Certificate Registrar may choose. Such purported Transferee shall promptly endorse and deliver each Residual Certificate in accordance with the instructions of the Certificate Registrar. Such purchaser may be the Certificate Registrar itself or any Affiliate of the Certificate Registrar. The proceeds of such sale, net of the commissions (which may include commissions payable to the Certificate Registrar or its Affiliates), expenses and taxes due, if any, shall be remitted by the Certificate Registrar 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 Certificate Registrar, and the Certificate Registrar shall not be liable to any Person having an Ownership Interest in a Residual Certificate as a result of its exercise of such discretion.

(iv)        The Trustee shall make available to the Internal Revenue Service and those Persons specified by the REMIC Provisions all information necessary to compute any tax imposed (A) as a result of the Transfer of an Ownership Interest in a Residual

Certificate to any Person who is a Disqualified Organization, including the information described in Treasury regulations sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the “excess inclusions” of such Residual Certificate 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 Residual Certificate having as among its record Holders at any time any Person which is a Disqualified Organization. Reasonable compensation for providing such information may be accepted by the Trustee.

(v)        The provisions of this Section 5.02(d) set forth prior to this subsection (v) may be modified, added to or eliminated, provided that there shall have been delivered to the Trustee at the expense of the party seeking to modify, add to or eliminate any such provision the following:

(A) written notification from each Rating Agency to the effect that the modification, addition to or elimination of such provisions shall not cause such Rating Agency to downgrade its then-current ratings of any Class of Certificates; and

(B) an Opinion of Counsel, in form and substance satisfactory to the Trustee, to the effect that such modification of, addition to or elimination of such provisions shall not cause any Trust REMIC to cease to qualify as a REMIC and shall not cause any Trust REMIC, as the case may be, to be subject to an entity-level tax caused by the Transfer of any Residual Certificate to a Person that is not a Permitted Transferee or (y) a Person other than the prospective transferee to be subject to a REMIC-tax caused by the Transfer of a Residual Certificate to a Person that is not a Permitted Transferee.

The Trustee shall forward to the NIMS Insurer and the Guarantor a copy of the items delivered to it pursuant to (A) and (B) above.

(e)        Subject to the preceding subsections, 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, 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 the same Class of a like aggregate Percentage Interest.

(f)         At the option of the Holder thereof, any Certificate may be exchanged for other Certificates of the same Class with authorized denominations and a like aggregate Percentage Interest, upon surrender of such Certificate to be exchanged at any office or agency of the Trustee maintained for such purpose pursuant to Section 8.12. Whenever any Certificates are so surrendered for exchange the Trustee shall execute and cause the Certificate Registrar to authenticate and deliver the Certificates 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) be duly endorsed by, or be accompanied by a written instrument of transfer in the form satisfactory to the Trustee and the Certificate Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing. In addition, with respect to each Residual Certificate, the Holder thereof may exchange, in the manner described above, the Class

R Certificate for three separate Certificates, each representing such Holder’s respective Percentage Interest in the Class R-I Interest, the Class R-II Interest and the Class R-III Interest, respectively, in each case that was evidenced by the Class R Certificate being exchanged and (ii) with respect to each Class R-X Certificate, the Holder thereof may exchange, in the manner described above, such Class R-X Certificate for three separate Certificates, each representing such Holder’s respective Percentage Interest in the Class R-IV Interest, the Class R-V Interest and the Class R-VI Interest, respectively, in each case that was evidenced by the Class R-X Certificate being exchanged.

(g)        No service charge to the Certificateholders shall be made for any transfer or exchange of Certificates, 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 canceled and destroyed by the Certificate Registrar in accordance with its customary procedures.

(i)         The Trustee shall cause the Certificate Registrar (unless the Trustee is acting as Certificate Registrar) to provide notice to the Trustee of each transfer of a Certificate and to provide the Trustee with an updated copy of the Certificate Register on the first Business Day in March and August of each year, commencing in March 2006.

(j)         Any attempted or purported transfer of any Certificate in violation of the provisions of Section 5.02(c) hereof shall be void ab initio and such Certificate shall be considered to have been held continuously by the prior permitted Holder.

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

If (i) any mutilated Certificate is surrendered to the Trustee or 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, the NIMS Insurer, the Guarantor 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 actual knowledge by the Trustee or the Certificate Registrar that such Certificate has been acquired by a bona fide purchaser or the Trustee shall execute and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of the same Class and of like denomination and Percentage Interest. 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 Certificate Registrar) connected therewith. Any replacement Certificate issued pursuant to this Section shall constitute complete and indefeasible evidence of ownership in the applicable REMIC created hereunder, 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.

The Depositor, the Master Servicer, the Trustee, the NIMS Insurer, the Guarantor, the Certificate Registrar and any agent of any of them 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 4.01 and for all other purposes whatsoever, and none of the Depositor, the Master Servicer, the Trustee, the Certificate Registrar, the NIMS Insurer, the Guarantor or any agent of any of them shall be affected by notice to the contrary.

SECTION 5.05. Certain Available Information.

On or prior to the date of the first sale of any Private Certificate to an Independent third party, the Depositor shall provide to the Trustee ten copies of any private placement memorandum or other disclosure document used by the Depositor in connection with the offer and sale of the Private Certificates. In addition, if any such private placement memorandum or disclosure document is revised, amended or supplemented at any time following the delivery thereof to the Trustee, the Depositor promptly shall inform the Trustee of such event and shall deliver to the Trustee ten copies of the private placement memorandum or disclosure document, as revised, amended or supplemented. The Trustee shall maintain at its Corporate Trust Office and shall make available free of charge during normal business hours for review by any Holder of a Certificate and/or Certificate Owner or any Person identified to the Trustee as a prospective transferee of a Certificate, originals or copies of the following items: (i) in the case of a Holder, Certificate Owner or prospective transferee of a Private Certificate, the private placement memorandum or other disclosure document relating to such Certificate, if any, in the form most recently provided to the Trustee; and (ii) in all cases, (A) this Agreement and any amendments hereof entered into pursuant to Section 11.01, (B) all monthly statements required to be delivered to Certificateholders of the relevant Class pursuant to Section 4.02 since the Closing Date, and all other notices, reports, statements and written communications delivered to the Certificateholders of the relevant Class pursuant to this Agreement since the Closing Date, (C) all certifications delivered by a Responsible Officer of the Trustee since the Closing Date pursuant to Section 10.01(h), (D) any and all Officers’ Certificates delivered to the Trustee by the Master Servicer since the Closing Date to evidence the Master Servicer’s determination that any Advance or Servicing Advance was, or if made, would be a Nonrecoverable Advance or Nonrecoverable Servicing Advance, respectively, and (E) any and all Officers’ Certificates delivered to the Trustee by the Master Servicer since the Closing Date pursuant to Section 4.04(a). Copies and mailing of any and all of the foregoing items shall be available from the Trustee upon request at the expense of the person requesting the same.

ARTICLE VI

THE DEPOSITOR AND THE MASTER SERVICER

SECTION 6.01. Liability of the Depositor and the Master Servicer.

The Depositor and the Master Servicer each shall be liable in accordance herewith only to the extent of the obligations specifically imposed by this Agreement and undertaken hereunder by the Depositor and the Master Servicer herein.

SECTION 6.02. Merger or Consolidation of the Depositor or the Master Servicer.

Subject to the following paragraph, the Depositor shall keep in full effect its existence, rights and franchises as a corporation under the laws of the jurisdiction of its incorporation. Subject to the following paragraph, the Master Servicer shall keep in full effect its existence, rights and franchises as a corporation under the laws of the jurisdiction of its incorporation and its qualification as an approved conventional seller/servicer for Fannie Mae or Freddie Mac in good standing. The Depositor and the Master Servicer each shall 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.

The Depositor or the Master Servicer may be merged or consolidated with or into any Person, or transfer all or substantially all of its assets to any Person, in which case any Person 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 the Rating Agencies’ ratings of the Class A Certificates and the Mezzanine Certificates in effect immediately prior to such merger or consolidation shall not be qualified, reduced or withdrawn as a result thereof (as evidenced by a letter to such effect from the Rating Agencies).

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

None of the Depositor, the Guarantor, the NIMS Insurer, the Master Servicer or any of the directors, officers, employees or agents of the Depositor, the Guarantor 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 Guarantor, the NIMS Insurer, the Master Servicer or any such person against any breach of warranties, representations or covenants made herein, or against any specific liability imposed on

the Master Servicer pursuant hereto, or against any liability which would otherwise be imposed by reason of willful misfeasance, bad faith or negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder. The Depositor, the Guarantor, the NIMS Insurer, the Master Servicer or the Trustee and any director, officer, employee or agent of the Depositor, the Guarantor, the NIMS Insurer, the Master Servicer or the Trustee may rely in good faith on any document of any kind which, prima facie, is properly executed and submitted by any Person respecting any matters arising hereunder.

The Depositor, the Guarantor, the NIMS Insurer, the Master Servicer and any director, officer, employee or agent of the Depositor, the Guarantor, the NIMS Insurer, or the Master Servicer shall be indemnified and held harmless by the Trust Fund 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 relating to any specific Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement) or, in the case of the Depositor and the Master Servicer, any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder. None of the Depositor, the Guarantor, the NIMS Insurer or the Master Servicer shall be under any obligation to appear in, prosecute or defend any legal action unless such action is related to its respective duties under this Agreement and, in its opinion, does not involve it in any expense or liability; provided, however, that each of the Depositor, the Guarantor, the NIMS Insurer and the Master Servicer may in its discretion undertake any such action which it may deem necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, unless the Depositor or the Master Servicer acts without the consent of the Holders of Certificates entitled to at least 51% of the Voting Rights (which consent shall not be necessary in the case of litigation or other legal action by either to enforce their respective rights or defend themselves hereunder), the legal expenses and costs of such action and any liability resulting therefrom (except any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder) shall be expenses, costs and liabilities of the Trust Fund, and the Depositor, the Guarantor, the NIMS Insurer and the Master Servicer shall be entitled to be reimbursed therefor from the Collection Account as and to the extent provided in Section 3.05, any such right of reimbursement being prior to the rights of the Certificateholders to receive any amount in the Collection Account.

The Master Servicer (except the Trustee to the extent it has succeeded the Master Servicer as required hereunder) shall indemnify and hold the Guarantor harmless against any and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, fees and expenses that the Guarantor may sustain in any way related to the failure of the Master Servicer to perform its duties and service the Mortgage Loans in compliance with the terms of this Agreement. The Master Servicer shall immediately notify the Guarantor if a claim is made that may result in such claims, losses, penalties, fines, forfeitures, legal fees or related costs, judgments, or any other costs, fees and expenses, and the Master Servicer shall assume the defense of any such claim and pay all expenses in connection therewith, including reasonable counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against the Guarantor in respect of such claim. The

provisions of this paragraph shall survive the termination of this Agreement and the payment of the outstanding Certificates.

SECTION 6.04. Limitation on Resignation of the Master Servicer.

The Master Servicer shall not resign from the obligations and duties hereby imposed on it except (i) upon determination that its duties hereunder are no longer permissible under applicable law or (ii) with the written consent of the Trustee, the NIMS Insurer or the Guarantor (as provided in Section 1.03) and written confirmation from each Rating Agency (which confirmation shall be furnished to the Depositor, the NIMS Insurer, the Guarantor and the Trustee) that such resignation shall not cause such Rating Agency to reduce the then current rating of the Class A Certificates or the Mezzanine Certificates. Any such determination pursuant to clause (i) of the preceding sentence, permitting the resignation of the Master Servicer, shall be evidenced by an Opinion of Counsel to such effect obtained at the expense of the Master Servicer and delivered to the Trustee, the Guarantor and the NIMS Insurer. No resignation of the Master Servicer shall become effective until the Trustee or a successor servicer acceptable to the NIMS Insurer or the Guarantor (as provided in Section 1.03) shall have assumed the Master Servicer’s responsibilities, duties, liabilities (other than those liabilities arising prior to the appointment of such successor) and obligations under this Agreement.

Except as expressly provided herein, the Master Servicer shall not assign or transfer any of its rights, benefits or privileges hereunder to any other Person, nor delegate to or subcontract with, nor authorize or appoint any other Person to perform any of the duties, covenants or obligations to be performed by the Master Servicer hereunder. If, pursuant to any provision hereof, the duties of the Master Servicer are transferred to a successor master servicer, the entire amount of the Servicing Fee and other compensation payable to the Master Servicer pursuant hereto shall thereafter be payable to such successor master servicer.

SECTION 6.05. Rights of the Depositor in Respect of the Master Servicer.

The Master Servicer shall afford (and any Sub-Servicing Agreement shall provide that each Sub-Servicer shall afford) the Depositor, the NIMS Insurer, the Guarantor and the Trustee, upon reasonable advance notice in writing, during normal business hours at the office designated by the Master Servicer, access to all records maintained by the Master Servicer (and any such Sub-Servicer) in respect of the Master Servicer’s rights and obligations with respect to the Mortgage Loans hereunder and access to officers of the Master Servicer (and those of any such Sub-Servicer) responsible for such obligations. Upon reasonable advance notice in writing, the Master Servicer shall furnish to the Depositor, the NIMS Insurer, the Guarantor and the Trustee its (and any such Sub-Servicer’s) most recent financial statements and such other information relating to the Master Servicer’s capacity to perform its obligations under this Agreement that it possesses. To the extent such information is not otherwise available to the public, the Depositor, the NIMS Insurer, the Guarantor and the Trustee shall not disseminate any information obtained pursuant to the preceding two sentences without the Master Servicer’s (or any such Sub-Servicer’s) written consent, except as required pursuant to this Agreement or to the extent that it is appropriate to do so (i) in working with legal counsel, auditors, taxing authorities or other governmental agencies, rating agencies or reinsurers or (ii) pursuant to any law, rule, regulation, order, judgment, writ, injunction or decree of any court or governmental authority

having jurisdiction over the Depositor, the Guarantor, the Trustee or the Trust Fund, and in either case, the Depositor, the NIMS Insurer, the Guarantor or the Trustee, as the case may be, shall use its best efforts to assure the confidentiality of any such disseminated non-public information. The Depositor may, but is not obligated to, enforce the obligations of the Master Servicer under this Agreement and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of the Master Servicer under this Agreement or exercise the rights of the Master Servicer under this Agreement; provided that the Master Servicer shall not be relieved of any of its obligations under this Agreement by virtue of such performance by the Depositor or its designee. The Depositor shall not have any responsibility or liability for any action or failure to act by the Master Servicer and is not obligated to supervise the performance of the Master Servicer under this Agreement or otherwise.

SECTION 6.06. Sub-Servicing Agreements Between the Master Servicer and Sub-Servicers.

(a)        The Master Servicer may enter into Sub-Servicing Agreements (provided that (i) such agreements would not result in a withdrawal or a downgrade by any Rating Agency of the ratings on any Class of Certificates, as evidenced by a letter to that effect delivered to the Depositor, the Trustee, the NIMS Insurer and the Guarantor and (ii) the NIMS Insurer or the Guarantor (as provided in Section 1.03) shall have consented to such Sub-Servicing Agreement with Sub-Servicers, for the servicing and administration of the Mortgage Loans.

Each Sub-Servicer shall be (i) 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 Sub-Servicer to perform its obligations hereunder and under the Sub-Servicing Agreement, (ii) an institution approved as a mortgage loan originator by the Federal Housing Administration or an institution the deposit accounts in which are insured by the FDIC and (iii) a Freddie Mac or Fannie Mae approved mortgage servicer. Each Sub-Servicing Agreement must impose on the Sub-Servicer requirements conforming to the provisions set forth in Section 6.11 and provide for servicing of the Mortgage Loans consistent with the terms of this Agreement. The Master Servicer shall examine each Sub-Servicing Agreement and shall be familiar with the terms thereof. The terms of any Sub-Servicing Agreement shall not be inconsistent with any of the provisions of this Agreement. The Master Servicer and the Sub-Servicers may enter into and make amendments to the Sub-Servicing Agreements or enter into different forms of Sub-Servicing Agreements; provided, however, that any such amendments or different forms shall be consistent with and not violate the provisions of this Agreement, and that no such amendment or different form shall be made or entered into which could be reasonably expected to be materially adverse to the interests of the Certificateholders, without the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights. Any variation without the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights from the provisions set forth in Section 6.11, provisions relating to insurance in Section 3.10 or priority requirements of Sub-Servicing Accounts, or credits and charges to the Sub-Servicing Accounts or the timing and amount of remittances by the Sub-Servicers to the Master Servicer, are conclusively deemed to be inconsistent with this Agreement and therefore prohibited. The Master Servicer shall deliver to the Trustee, the Guarantor and the NIMS Insurer copies of all Sub-Servicing Agreements, and any amendments or modifications thereof, promptly upon the Master Servicer’s execution and delivery of such instruments.

(b)       As part of its servicing activities hereunder, the Master Servicer (except as otherwise provided in the last sentence of this paragraph), for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Sub-Servicer under the related Sub-Servicing Agreement and of the Seller under the Mortgage Loan Purchase Agreement, including, without limitation, any obligation to make advances in respect of delinquent payments as required by a Sub-Servicing Agreement, or to purchase a Mortgage Loan on account of missing or defective documentation or on account of a breach of a representation, warranty or covenant, as described in Section 2.03(a). Such enforcement, including, without limitation, the legal prosecution of claims, termination of Sub-Servicing Agreements, and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, 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 Loans or (ii) from a specific recovery of costs, expenses or attorneys’ fees against the party against whom such enforcement is directed.

SECTION 6.07. Successor Sub-Servicers.

The Master Servicer (with the consent of the NIMS Insurer or the Guarantor as provided in Section 1.03) and the Guarantor, with respect to the Group I Mortgage Loans only, shall be entitled to terminate any Sub-Servicing Agreement and the rights and obligations of any Sub-Servicer pursuant to any Sub-Servicing Agreement in accordance with the terms and conditions of such Sub-Servicing Agreement. In the event of termination of any Sub-Servicer, all servicing obligations of such Sub-Servicer shall be assumed simultaneously by the Master Servicer without any act or deed on the part of such Sub-Servicer or the Master Servicer, and the Master Servicer either shall service directly the related Mortgage Loans or shall enter into a Sub-Servicing Agreement with a successor Sub-Servicer which qualifies under Section 6.06.

Any Sub-Servicing Agreement shall include the provision that such agreement may be immediately terminated by the Trustee without fee, in accordance with the terms of this Agreement, in the event that the Master Servicer shall, for any reason, no longer be the Master Servicer (including termination due to a Master Servicer Event of Default).

SECTION 6.08. Liability of the Master Servicer.

Notwithstanding any Sub-Servicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between the Master Servicer and a Sub-Servicer or reference to actions taken through a Sub-Servicer or otherwise, the Master Servicer shall remain obligated and primarily liable to the Trustee and the 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 Sub-Servicing Agreements or arrangements or by virtue of indemnification from the Sub-Servicer 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 Sub-Servicer for indemnification of the Master Servicer by such Sub-

Servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

SECTION 6.09. No Contractual Relationship Between Sub-Servicers and the NIMS Insurer, the Guarantor, the Trustee or Certificateholders.

Any Sub-Servicing Agreement that may be entered into and any transactions or services relating to the Mortgage Loans involving a Sub-Servicer in its capacity as such shall be deemed to be between the Sub-Servicer and the Master Servicer alone, and the NIMS Insurer, the Guarantor, the Trustee and Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Sub-Servicer except as set forth in Section 6.10. The Master Servicer shall be solely liable for all fees owed by it to any Sub-Servicer, irrespective of whether the Master Servicer’s compensation pursuant to this Agreement is sufficient to pay such fees.

SECTION 6.10. Assumption or Termination of Sub-Servicing Agreements by Trustee.

In the event the Master Servicer shall for any reason no longer be the master servicer (including termination due to a Master Servicer Event of Default), the Trustee or its designee shall thereupon assume (or cause its designee or the successor master servicer for the Trustee appointed pursuant to Section 7.02 to assume) all of the rights and obligations of the Master Servicer under each Sub-Servicing Agreement that the Master Servicer may have entered into, unless the Trustee elects to terminate any Sub-Servicing Agreement in accordance with its terms as provided in Section 6.07. Upon such assumption, the Trustee, its designee or the successor servicer for the Trustee appointed pursuant to Section 7.02 shall be deemed, subject to Section 6.07, to have assumed all of the Master Servicer’s interest therein and to have replaced the Master Servicer as a party to each Sub-Servicing Agreement to the same extent as if each Sub-Servicing Agreement had been assigned to the assuming party, except that (i) the Master Servicer shall not thereby be relieved of any liability or obligations under any Sub-Servicing Agreement and (ii) none of the Trustee, its designee or any successor Master Servicer shall be deemed to have assumed any liability or obligation of the Master Servicer that arose before it ceased to be the Master Servicer.

The Master Servicer at its expense shall, upon request of the Trustee, deliver to the assuming party all documents and records relating to each Sub-Servicing Agreement and the Mortgage Loans then being serviced and an accounting of amounts collected and held by or on behalf of it, and otherwise use its best efforts to effect the orderly and efficient transfer of the Sub-Servicing Agreements to the assuming party.

SECTION 6.11. Sub-Servicing Accounts.

In those cases where a Sub-Servicer is servicing a Mortgage Loan pursuant to a Sub-Servicing Agreement, the Sub-Servicer shall be required to establish and maintain one or more accounts (collectively, the “Sub-Servicing Account”). The Sub-Servicing Account shall be an Eligible Account. The Sub-Servicer shall deposit in the clearing account (which account must be an Eligible Account) in which it customarily deposits payments and collections on mortgage

loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Sub-Servicer’s receipt thereof, all proceeds of Mortgage Loans received by the Sub-Servicer less its servicing compensation to the extent permitted by the Sub-Servicing Agreement, and shall thereafter deposit such amounts in the Sub-Servicing Account, in no event more than two Business Days after the deposit of such funds into the clearing account. The Sub-Servicer shall thereafter deposit such proceeds in the Collection Account or remit such proceeds to the Master Servicer for deposit in the Collection Account not later than two Business Days after the deposit of such amounts in the Sub-Servicing Account. For purposes of this Agreement, the Master Servicer shall be deemed to have received payments on the Mortgage Loans when the Sub-Servicer receives such payments.

SECTION 7.01. Master Servicer Events of Default.

“Master Servicer Event of Default,” wherever used herein, means any one of the following events:

(i)         any failure by the Master Servicer to remit to the Trustee for distribution to the Certificateholders any payment (other than an Advance required to be made from its own funds on any Master Servicer Remittance Date pursuant to Section 4.03) required to be made under the terms of the Certificates and this Agreement which continues unremedied for a period of one Business Day after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Depositor or the Trustee (in which case notice shall be provided by telecopy), or to the Master Servicer, the Depositor and the Trustee by the NIMS Insurer, the Guarantor or the Holders of Certificates entitled to at least 25% of the Voting Rights; or

(ii)         any failure on the part of the Master Servicer duly to observe or perform in any material respect any of the covenants or agreements on the part of the Master Servicer contained in the Certificates or in this Agreement (or, if the Master Servicer is the Seller, the failure of the Seller to repurchase a Mortgage Loan as to which a breach has been established that requires a repurchase pursuant to the terms of Section 7 of the Mortgage Loan Purchase Agreement) which continues unremedied for a period of 45 days after the earlier of (i) 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 Depositor or the Trustee, or to the Master Servicer, the Depositor and the Trustee by the NIMS Insurer, the Guarantor or the Holders of Certificates entitled to at least 25% of the Voting Rights and (ii) actual knowledge of such failure by a Servicing Officer of the Master Servicer; 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 the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceeding, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and if such proceeding is being contested by the Master Servicer in good faith, such decree or order shall have remained in force undischarged or unstayed for a period of 60 days or results in the entry of an order for relief or any such adjudication or appointment; or

(iv)        the Master Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the Master Servicer or of or relating to all or substantially all of its property; 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 any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations;

(vi) the Master Servicer ceases to be an approved servicer of Fannie Mae;

(vii)       any failure by the Master Servicer of the Master Servicer Termination Test;

(viii)      any failure of the Master Servicer to make any Advance on any Master Servicer Remittance Date required to be made from its own funds pursuant to Section 4.03 which continues unremedied until 3:00 p.m. New York time on the Business Day immediately following the Master Servicer Remittance Date.

If a Master Servicer Event of Default described in clauses (i) through (vi) of this Section shall occur, then, and in each and every such case, so long as such Master Servicer Event of Default shall not have been remedied, the Depositor, the NIMS Insurer or the Trustee may, at the written direction of the Holders of Certificates entitled to at least 51% of Voting Rights, or at the direction of the NIMS Insurer or the Guarantor (as provided in Section 1.03), the Trustee shall, by notice in writing to the Master Servicer, the Guarantor and the Depositor, terminate all of the rights and obligations of the Master Servicer in its capacity as Master Servicer under this Agreement, to the extent permitted by law, and in and to the Mortgage Loans and the proceeds thereof. If a Master Servicer Event of Default described in clause (vii) hereof shall occur, the Trustee shall, by notice in writing to the Master Servicer, the Guarantor and the Depositor, terminate all of the rights and obligations of the Master Servicer in its capacity as Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof and the Trustee as successor Master Servicer or a successor Master Servicer appointed in accordance with Section 7.02, shall immediately make such Advance(subject to its own determination as to recoverability, which Advance shall be part of Available Funds for such Distribution Date) and assume, pursuant to Section 7.02, the duties of a successor Master Servicer. 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 of any Certificate) or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee pursuant to and under this Section and, without limitation, the Trustee is hereby authorized and empowered, as attorney-in-fact or otherwise, to execute and deliver on behalf of and at the expense of the Master Servicer, 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, at its sole cost and expense, promptly (and in any event no later than ten Business Days subsequent to such notice) to provide the Trustee with all documents and records requested by it to enable it to assume the Master Servicer’s functions under this Agreement, and to cooperate with the Trustee in effecting the termination of the Master Servicer’s responsibilities and rights under this Agreement, including, without limitation, the transfer within one Business Day to the Trustee for administration by it of all cash amounts which at the time shall be or should have been credited by the Master Servicer to the Collection Account held by or on behalf of the Master Servicer, the

Distribution Account or any REO Account or Escrow Account held by or on behalf of the Master Servicer or thereafter be received with respect to the Mortgage Loans or any REO Property serviced by the Master Servicer (provided, however, that the Master Servicer shall continue to be entitled to receive all amounts accrued or owing to it under this Agreement on or prior to the date of such termination, whether in respect of Advances or otherwise, and shall continue to be entitled to the benefits of Section 6.03, notwithstanding any such termination, with respect to events occurring prior to such termination). For purposes of this Section 7.01, the Trustee shall not be deemed to have knowledge of a Master Servicer Event of Default unless a Responsible Officer of the Trustee assigned to and working in the Trustee’s Corporate Trust Office has actual knowledge thereof or unless written notice is received by the Trustee of any such event and such notice references the Certificates, REMIC I or this Agreement.

The Trustee shall be entitled to be reimbursed by the Master Servicer (or by the Trust Fund if the Master Servicer is unable to fulfill its obligations hereunder) for all costs associated with the transfer of servicing from the predecessor servicer, including without limitation, any costs or expenses associated with the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data as may be required by the Trustee to correct any errors or insufficiencies in the servicing data or otherwise to enable the Trustee to service the Mortgage Loans properly and effectively.

SECTION 7.02. Trustee to Act; Appointment of Successor.

(a)        On and after the time the Master Servicer receives a notice of termination, the Trustee shall be the successor in all respects to the Master Servicer in its capacity as Master 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 and arising thereafter placed on the Master Servicer (except for any representations or warranties of the Master Servicer under this Agreement, the responsibilities, duties and liabilities contained in Section 2.03(c) and its obligation to deposit amounts in respect of losses pursuant to Section 3.06) by the terms and provisions hereof including, without limitation, the Master Servicer’s obligations to make Advances pursuant to Section 4.03; provided, however, that if the Trustee is prohibited by law or regulation from obligating itself to make advances regarding delinquent mortgage loans, then the Trustee shall not be obligated to make Advances pursuant to Section 4.03; and provided further, that any failure to perform such duties or responsibilities caused by the Master Servicer’s failure to provide information required by Section 7.01 shall not be considered a default by the Trustee as successor to the Master Servicer hereunder; provided, however, it is understood and acknowledged by the parties that there shall be a period of transition (not to exceed 90 days) before the servicing transfer is fully effected. As compensation therefor, effective from and after the time the Master Servicer receives a notice of termination or immediately upon assumption of the obligations to make Advances, the Trustee shall be entitled to the Servicing Fee and all funds relating to the Mortgage Loans to which the Master Servicer would have been entitled if it had continued to act hereunder (other than amounts which were due or would become due to the Master Servicer prior to its termination or resignation). Notwithstanding the above and subject to the next paragraph, the Trustee may, if it shall be unwilling to so act, or shall, if it is unable to so act or if it is prohibited by law from making advances regarding delinquent mortgage loans, or if the Holders of Certificates entitled to at least 51% of the Voting Rights or the NIMS Insurer or the Guarantor (as provided in Section 1.03) so request in writing to the Trustee promptly appoint

or petition a court of competent jurisdiction to appoint, an established mortgage loan servicing institution acceptable to each Rating Agency and the NIMS Insurer or the Guarantor (as provided in Section 1.03) and having a net worth of not less than $15,000,000 as the successor to the Master Servicer under this Agreement in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer under this Agreement. No appointment of a successor to the Master Servicer under this Agreement shall be effective until the assumption by the successor of all of the Master Servicer’s responsibilities, duties and liabilities hereunder. In connection with such appointment and assumption described herein, 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 Master Servicer as such hereunder. The Depositor, the Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Pending appointment of a successor to the Master Servicer under this Agreement, the Trustee shall act in such capacity as hereinabove provided.

Upon removal or resignation of the Master Servicer, the Trustee, with the cooperation of the Depositor, (x) shall solicit bids for a successor Master Servicer as described below and (y) pending the appointment of a successor Master Servicer as a result of soliciting such bids, shall serve as Master Servicer of the Mortgage Loans serviced by such predecessor Master Servicer. The Trustee shall solicit, by public announcement, bids from housing and home finance institutions, banks and mortgage servicing institutions meeting the qualifications set forth above (including the Trustee or any affiliate thereof) (including that such mortgage loan servicing institution shall be acceptable to each Rating Agency and the NIMS Insurer or the Guarantor (as provided in Section 1.03)). Such public announcement shall specify that the successor Master Servicer shall be entitled to the servicing compensation agreed upon between the Trustee, the successor Master Servicer and the Depositor; provided, however, that no such fee shall exceed the Servicing Fee. Within thirty days after any such public announcement, the Trustee, with the cooperation of the Depositor, shall negotiate in good faith and effect the sale, transfer and assignment of the servicing rights and responsibilities hereunder to the qualified party submitting the highest satisfactory bid as to the price they shall pay to obtain such servicing. The Trustee upon receipt of the purchase price shall pay such purchase price to the Master Servicer being so removed, after deducting from any sum received by the Trustee from the successor to the Master Servicer in respect of such sale, transfer and assignment all costs and expenses of any public announcement and of any sale, transfer and assignment of the servicing rights and responsibilities reasonably incurred hereunder. After such deductions, the remainder of such sum shall be paid by the Trustee to the Master Servicer at the time of such sale.

(b)        If the Master Servicer fails to remit to the Trustee for distribution to the Certificateholders any payment required to be made under the terms of the Certificates and this Agreement (for purposes of this Section 7.02(b), a “Remittance”) because the Master Servicer is the subject of a proceeding under the federal Bankruptcy Code and the making of such Remittance is prohibited by Section 362 of the federal Bankruptcy Code, the Trustee shall upon notice of such prohibition, regardless of whether it has received a notice of termination under Section 7.01, advance the amount of such Remittance by depositing such amount in the Distribution Account on the related Distribution Date. The Trustee shall be obligated to make such advance only if (i) such advance, in the good faith judgment of the Trustee can reasonably be expected to be ultimately recoverable from Stayed Funds and (ii) the Trustee is not prohibited

by law from making such advance or obligating itself to do so. Upon remittance of the Stayed Funds to the Trustee or the deposit thereof in the Distribution Account by the Master Servicer, a trustee in bankruptcy or a federal bankruptcy court, the Trustee may recover the amount so advanced, without interest, by withdrawing such amount from the Distribution Account; however, nothing in this Agreement shall be deemed to affect the Trustee’s rights to recover from the Master Servicer’s own funds interest on the amount of any such advance. If the Trustee at any time makes an advance under this Subsection which it later determines in its good faith judgment shall not be ultimately recoverable from the Stayed Funds with respect to which such advance was made, the Trustee shall be entitled to reimburse itself for such advance, without interest, by withdrawing from the Distribution Account, out of amounts on deposit therein, an amount equal to the portion of such advance attributable to the Stayed Funds.

(c)       If the Master Servicer is terminated pursuant to Section 7.01, then the successor Master Servicer shall not be permitted to reimburse itself directly for Advances or Servicing Advances under Section 3.05(a)(ii), Section 3.05(a)(iii), Section 3.05(a)(v) or Section 3.05(a)(vii) if the Master Servicer has not been fully reimbursed for its Advances and Servicing Advances, but instead the successor Master Servicer shall include such amounts in the applicable remittance to the Trustee made pursuant to Section 3.04(g) to the extent of amounts on deposit in the Collection Account on the related Master Servicer Remittance Date. The Trustee is hereby authorized to pay to the terminated Master Servicer (or the related Advancing Person in accordance with Section 3.23) and the successor Master Servicer, as applicable, reimbursements for Advances and Servicing Advances from the Distribution Account to the same extent each such Master Servicer would have been permitted to reimburse itself for such Advances and/or Servicing Advances in accordance with Section 3.05(a)(ii), Section 3.05(a)(iii), Section 3.05(a)(v) or Section 3.05(a)(vii), as the case may be. All Advances and Servicing Advances made pursuant to the terms of this Agreement shall be deemed made and shall be reimbursed on a “first in-first out” (FIFO) basis. At such time as the Master Servicer (or related Advancing Person) has been reimbursed for all Advances and Servicing Advances made by it, the successor Master Servicer shall no longer be required to remit in accordance with the first sentence of this Section 7.02(c) and shall then be permitted to reimburse itself directly for Advances and Servicing Advances in accordance with Section 3.05(a)(ii), Section 3.05(a)(iii), Section 3.05(a)(v) or Section 3.05(a)(vii).

SECTION 7.03. Notification to Certificateholders.

(a)        Upon any termination of the Master Servicer pursuant to Section 7.01 above or any appointment of a successor to the Master Servicer pursuant to Section 7.02 above, the Trustee shall give prompt written notice thereof to Certificateholders, the Guarantor and the NIMS Insurer at their respective addresses appearing in the Certificate Register.

(b)        Not later than the later of 60 days after the occurrence of any event, which constitutes or which, with notice or lapse of time or both, would constitute a Master Servicer Event of Default or five days after a Responsible Officer of the Trustee becomes aware of the occurrence of such an event, the Trustee shall transmit by mail to the NIMS Insurer, the Guarantor and to all Holders of Certificates notice of each such occurrence, unless such default or Master Servicer Event of Default shall have been cured or waived.

SECTION 7.04. Waiver of Master Servicer Events of Default.

The Holders representing at least 66% of the Voting Rights (with the consent of the NIMS Insurer or the Guarantor (as provided in Section 1.03)) evidenced by all Classes of Certificates affected by any default or Master Servicer Event of Default hereunder may waive such default or Master Servicer Event of Default; provided, however, that a default or Master Servicer Event of Default under clause (i) or (vii) of Section 7.01 may be waived only by all of the Holders of the Regular Certificates (with the consent of the NIMS Insurer or the Guarantor (as provided in Section 1.03)). Upon any such waiver of a default or Master Servicer Event of Default, such default or Master Servicer 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 Master Servicer 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.

The Trustee, prior to the occurrence of a Master Servicer Event of Default and after the curing of all Master Servicer Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. During a Master Servicer Event of Default, 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 person would exercise or use under the circumstances in the conduct of such person’s own affairs. Any permissive right of the Trustee enumerated in this Agreement shall not be construed as a duty.

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 on their face to the requirements of this Agreement. If any such instrument is found not to conform on its face to the requirements of this Agreement in a material manner, the Trustee shall take such action as it deems appropriate to have the instrument corrected, and if the instrument is not corrected to its respective satisfaction, such dissatisfied party shall provide notice thereof to the Certificateholders, the Guarantor and the NIMS Insurer.

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 misconduct; provided, however, that:

(i)         Prior to the occurrence of a Master Servicer Event of Default, and after the curing of all such Master Servicer 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 that conform to 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; and

(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 NIMS Insurer, the Guarantor or the Holders of Certificates entitled to at least 25% of the Voting Rights relating 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 it, under this Agreement.

The Trustee shall not be required to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it, and none of the provisions contained in this Agreement shall in any event require it to perform, or be responsible for the manner of performance of, any of the obligations of the Master Servicer under this Agreement, except during such time, if any, as the Trustee shall be the successor to, and be vested with the rights, duties, powers and privileges of, the Master Servicer in accordance with the terms of this Agreement.

SECTION 8.02.		Certain Matters Affecting the Trustee.
(a)	Except as otherwise provided in Section 8.01:

(i)         The Trustee may request and rely upon 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 reasonably 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 not be under any 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, the Guarantor or the NIMS Insurer, pursuant to the provisions of this Agreement, unless such Certificateholders, the Guarantor or the NIMS Insurer, as applicable, shall have offered to the Trustee security or indemnity reasonably satisfactory to it 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 a Master Servicer Event of Default (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Agreement, and to use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’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 a Master Servicer Event of Default hereunder and after the curing of all Master Servicer 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 to do so by the NIMS Insurer, the Guarantor or the Holders of Certificates entitled to at least 25% of the Voting Rights; 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 Guarantor or such Certificateholders, the Trustee may require reasonable indemnity against such expense, or liability from such Certificateholders, the Guarantor or the NIMS Insurer as a condition to taking any such action;

(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; and

(vii)       The Trustee shall not be personally liable for any loss resulting from the investment of funds held in the Collection Account, the Escrow Account or the REO Account made at the direction of the Master Servicer pursuant to Section 3.06.

(b)        All rights of action under this Agreement or under any of the Certificates, enforceable by the Trustee, may be enforced by it without the possession of any of the Certificates, or the production thereof at the trial or other proceeding relating thereto, and any such suit, action or proceeding instituted by the Trustee shall be brought in the name of the Trustee for the benefit of all the Holders of such Certificates, subject to the provisions of this Agreement.

(c)        The Depositor hereby directs the Trustee to execute, deliver and perform its obligations under the Interest Rate Swap Agreement and to assign any rights to receive payments from the Swap Provider to the Swap Administrator pursuant to the Swap Administration Agreement and the Depositor further directs the Trustee to execute, deliver and perform its obligation under the Swap Administration Agreement. The Seller, the Depositor, the Master Servicer and the Holders of the Class A Certificates and the Mezzanine Certificates by their acceptance of such Certificates acknowledge and agree that the Trustee shall execute, deliver and perform its obligations under the Interest Rate Swap Agreement and the Swap Administration Agreement and shall do so solely in its capacity as Trustee of the Trust Fund or as Swap Administrator, as the case may be, and not in its individual capacity. Every provision of this Agreement relating to the conduct or affecting the liability of or affording protection to the Trustee shall apply to the Trustee’s execution of the Interest Rate Swap Agreement and the Swap Administration Agreement, and the performance of its duties and satisfaction of its obligations thereunder.

(d)        The Depositor hereby directs the Trustee to execute and deliver the Pool Policy on behalf of the Trust Fund in the form presented to it by the Depositor. Every provision of this Agreement relating to the conduct or affecting the liability of or affording protection to the Trustee shall apply to the Trustee’s execution of the Pool Policy, and the performance of its duties and satisfaction of its obligations thereunder.

SECTION 8.03. The Trustee Not Liable for Certificates or Mortgage Loans.

The recitals contained herein and in the Certificates (other than the signature of the Trustee, the authentication of the Certificate Registrar on the Certificates, the acknowledgments of the Trustee contained in Article II and the representations and warranties of the Trustee in Section 8.13) shall be taken as the statements of the Depositor and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations or warranties as to the validity or sufficiency of this Agreement (other than as specifically set forth with respect to such party in Section 8.13) or of the Certificates (other than the signature of the Trustee and authentication of the Certificate Registrar on the Certificates) or of any Mortgage Loan or related document. The Trustee shall not be accountable for the use or application by the Depositor of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Depositor or the Master Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Collection Account by the Master Servicer, other than, subject to Section 8.01, any funds held by or on behalf of the Trustee in accordance with Section 3.04.

SECTION 8.04. Trustee May Own Certificates.

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

SECTION 8.05. Trustee’s Fees and Expenses.

(a)        The Trustee shall withdraw from the Distribution Account on each Distribution Date and pay to itself the Trustee Fee and, to the extent that the funds therein are at any time insufficient for such purpose, the Depositor shall pay such fees. The Trustee, or any director, officer, employee or agent of the Trustee shall be indemnified by REMIC I and held harmless against any loss, liability or expense (not including expenses, disbursements and advances incurred or made by the Trustee (including the compensation and the expenses and disbursements of its agents and counsel) in the ordinary course of the Trustee’s performance in accordance with the provisions of this Agreement) incurred by the Trustee arising out of or in connection with the acceptance or administration of its obligations and duties under this Agreement, other than any loss, liability or expense (i) resulting from a breach of the Master Servicer’s obligations and duties under this Agreement and the Mortgage Loans (for which the Master Servicer shall indemnify pursuant to Section 8.05(b)), (ii) that constitutes a specific liability of the Trustee pursuant to Section 10.01(c) or (iii) any loss, liability or expense incurred by reason of its willful misfeasance, bad faith or negligence in the performance of its duties hereunder or by reason of reckless disregard of its obligations and duties hereunder or as a result of a breach of its obligations under Article X hereof.

If such corporation or association publishes reports of conditions at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of conditions 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.

The Trustee may at any time resign and be discharged from the trust hereby created by giving written notice thereof to the Depositor, the NIMS Insurer, the Guarantor, the Master Servicer and the Certificateholders. Upon receiving such notice of resignation of the Trustee, the Depositor shall promptly appoint a successor trustee acceptable to the NIMS Insurer or the Guarantor (as provided in Section 1.03) by written instrument, in duplicate, which instrument shall be delivered to the resigning Trustee and to the successor trustee. A copy of such instrument shall be delivered to the Certificateholders, the Guarantor, the Trustee and the Master Servicer by the Depositor. If no successor Trustee shall have been so appointed and shall have accepted appointment within 30 days after the giving of such notice of resignation, then the Guarantor may appoint a successor Trustee acceptable to the NIMS Insurer. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee.

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, the NIMS Insurer or the Guarantor (as provided in Section 1.03), 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 respective property shall be appointed, or any public officer shall take charge or control of the Trustee or of its respective property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Depositor, the NIMS Insurer or the Guarantor (as provided in Section 1.03) may remove the Trustee and appoint a successor trustee acceptable to the NIMS Insurer or the Guarantor (as provided in Section 1.03) by written instrument, in duplicate, which instrument shall be delivered to the Trustee so removed and to the successor trustee. A copy of

such instrument shall be delivered to the Certificateholders, the Guarantor and the Master Servicer by the Depositor.

Either (i) the Holders of Certificates entitled to at least 51% of the Voting Rights, with the consent of the NIMS Insurer or the Guarantor (as provided in Section 1.03) or (ii) the NIMS Insurer or the Guarantor (as provided in Section 1.03), upon failure of the Trustee to perform its obligations hereunder, may at any time remove the Trustee and appoint a successor trustee acceptable to the NIMS Insurer or the Guarantor (as provided in Section 1.03) 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. A copy of such instrument shall be delivered to the Certificateholders, the Guarantor and the Master Servicer by the Depositor.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor trustee as provided in Section 8.08.

SECTION 8.08. Successor Trustee.

Any successor trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Depositor, the NIMS Insurer, the Guarantor 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 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, as well as all moneys, held by it hereunder (other than any Mortgage Files at the time held by the Custodian, which Custodian shall become the agent of any successor trustee hereunder), and the Depositor and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties and obligations.

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 and the appointment of such successor trustee shall not result in a downgrading of any Class of Certificates by each Rating Agency, as evidenced by a letter from each Rating Agency.

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 association into which the Trustee may be merged or converted or with which it may be consolidated or any corporation or association resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or association succeeding to the business of the Trustee shall be the successor of the Trustee hereunder, provided such corporation or 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.

SECTION 8.10. Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of REMIC I 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 and the NIMS Insurer or the Guarantor (as provided in Section 1.03) to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of REMIC I, and to vest in such Person or Persons, in such capacity, such title to REMIC I, 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. Any such co-trustee or separate trustee shall be subject to the written approval of the Master Servicer and the NIMS Insurer or the Guarantor (as provided in Section 1.03). If the Master Servicer and the NIMS Insurer or the Guarantor (as provided in Section 1.03) shall not have joined in such appointment within 15 days after the receipt by it of a request so to do, or in case a Master Servicer 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 the Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08 hereof.

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 by the Trustee (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 REMIC I 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.

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 trust 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 and a copy thereof given to the Depositor, the Master Servicer, the Guarantor and the NIMS Insurer.

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 Depositor, the Guarantor and the Master Servicer appoint one or more Custodians to hold all or a portion of the Mortgage Files as agent for the Trustee, by entering into a custodial agreement. The appointment of any Custodian may at any time be terminated and a substitute Custodian appointed therefor upon the reasonable request of the Master Servicer to the Trustee, the consent to which shall not be unreasonably withheld. The Trustee, on behalf of the Trust Fund, shall pay any and all fees and expenses of the Custodian in accordance with Section 8.05. The Trustee initially appoints the Custodian as Custodian, and the Depositor and the Master Servicer consent to such appointment. Subject to Article VIII hereof, 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 having an interest in any Mortgage File held by such Custodian. Each Custodian shall be a depository institution or trust company subject to supervision by federal or state authority, shall have combined capital and surplus of at least $10,000,000 and shall be qualified to do business in the jurisdiction in which it holds any Mortgage File. Each custodial agreement may be amended only as provided in Section 11.01. In no event shall the appointment of any Custodian pursuant to a custodial agreement diminish the obligations of the Trustee hereunder.

SECTION 8.12. Appointment of Office or Agency.

The Trustee shall designate an office or agency in the City of New York where the Certificates may be surrendered for registration of transfer or exchange, and presented for final distribution, and where notices and demands to or upon the Trustee in respect of the Certificates and this Agreement may be delivered.

(iii)        It has the full power and authority to enter into and consummate all transactions contemplated by this Agreement, has duly authorized the execution, delivery and performance of this Agreement, and has duly executed and delivered this Agreement.

(v)        It is not in violation of, and its execution and delivery of this Agreement and its performance and compliance with the terms of this Agreement shall not constitute a violation of, any law, any order or decree of any court or arbiter, or any order, regulation or demand of any federal, state or local governmental or regulatory authority, which violation, in its good faith and reasonable judgment, is likely to affect materially and adversely either the ability of it to perform its obligations under this Agreement or its financial condition.

(vi)        No litigation is pending or, to the best knowledge, threatened against it which would prohibit it from entering into this Agreement or, in its good faith reasonable judgment, is likely to materially and adversely affect either its ability to perform its obligations under this Agreement or its financial condition.

ARTICLE IX

TERMINATION

SECTION 9.01. Termination Upon Repurchase or Liquidation of All Mortgage Loans.

(a)        Subject to Section 9.02, the respective obligations and responsibilities under this Agreement of the Depositor, the Guarantor, the Master Servicer and the Trustee (other than the obligations of the Master Servicer to the Trustee pursuant to Section 8.05 and of the Master Servicer to provide for and the Trustee to make payments in respect of the REMIC Regular Interests or the Classes of Certificates as hereinafter set forth) shall terminate upon payment to the Certificateholders and the deposit of all amounts held by or on behalf of the Trustee and required hereunder to be so paid or deposited on the Distribution Date coinciding with or following the earlier to occur of (i) the purchase by the Terminator (as defined below) of all Mortgage Loans and each REO Property remaining in REMIC I and (ii) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan or REO Property remaining in REMIC I; provided, however, that in no event shall the trust created hereby continue beyond the earlier of (a) the “latest possible maturity date” and (b) 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. The purchase by the Terminator of all Mortgage Loans and each REO Property remaining in REMIC I shall be at a price (the “Termination Price”) equal to greater of (A) the aggregate fair market value of all of the assets of REMIC I and (B) the sum of the Stated Principal Balance of the Mortgage Loans (after giving effect to scheduled payments of principal due during the related Due Period, to the extent received or advanced, and unscheduled collections of principal received during the related Prepayment Period) and the appraised fair market value of the REO Properties plus accrued interest through the end of the calendar month preceding the month of the final Distribution Date, any unreimbursed Advances and Servicing Advances and any Swap Termination Payment payable to the Swap Provider then remaining unpaid or which is due to the exercise of such option (in the case of fair market values required to be determined under (A) or (B) above, as determined by the Terminator, the Trustee and, if the Terminator is not the NIMS Insurer, the NIMS Insurer, as of the close of business on the third Business Day next preceding the date upon which notice of any such termination is furnished to Certificateholders pursuant to the third paragraph of this Section 9.01); provided, however, such option may only be exercised if the Termination Price is sufficient to pay (i) any outstanding Guarantor Reimbursement Amounts and Guaranty Fees owed to the Guarantor and (ii) all interest accrued on, as well as amounts necessary to retire the note balance of, each class of notes issued pursuant to the Indenture and any amounts owed to the NIMS Insurer at the time the option is exercised. If a termination pursuant to this Section 9.01(a) or Section 9.01(b) will result in a draw on the Guaranty, the consent of the Guarantor shall be required prior to the Terminator exercising such option.

(b)        The Master Servicer (or if the Master Servicer fails to exercise such right, the NIMS Insurer) shall have the right (the party exercising such right, the “Terminator”), to purchase all of the Mortgage Loans and each REO Property remaining in REMIC I pursuant to

clause (i) of the preceding paragraph no later than the Determination Date in the month immediately preceding the Distribution Date on which the Certificates shall be retired; provided, however, that the Terminator may elect to purchase all of the Mortgage Loans and each REO Property remaining in REMIC I pursuant to clause (i) above only (A) if the aggregate Stated Principal Balance of the Mortgage Loans and each REO Property remaining in the Trust Fund at the time of such election is less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date and (B) if the Terminator is the Master Servicer and is an affiliate of the Seller, the Master Servicer shall have delivered to the Trustee, the Guarantor and the NIMS Insurer a written certification that the burdens of servicing the Mortgage Loans and REO Properties remaining in REMIC I exceed the benefits of the Servicing Fees that would be realized by the Master Servicer if it continued to service such assets on behalf of the Trust Fund. By acceptance of the Residual Certificates, the Holders of the Residual Certificates agree, in connection with any termination hereunder, to pledge any amounts in excess of par, and to the extent received in respect of such termination, to pay any such amounts to the Holders of the Class CE Certificates.

(c)        Notice of the liquidation of the REMIC Regular Interests shall be given promptly by the Trustee by letter to Certificateholders mailed (a) in the event such notice is given in connection with the purchase of the Mortgage Loans and each REO Property by the Terminator, not earlier than the 15^th day and not later than the 25^th day of the month next preceding the month of the final distribution on the Certificates or (b) otherwise during the month of such final distribution on or before the Determination Date in such month, in each case specifying (i) the Distribution Date upon which the Trust Fund shall terminate and final payment in respect of the REMIC Regular Interests and the Certificates shall be made upon presentation and surrender of the related Certificates at the office of the Trustee therein designated, (ii) the amount of any such final payment, (iii) that no interest shall accrue in respect of the REMIC Regular Interests or the Certificates from and after the Interest Accrual Period relating to the final Distribution Date therefor and (iv) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office of the Trustee. The Trustee shall give such notice to the Certificate Registrar at the time such notice is given to Certificateholders. In the event such notice is given in connection with the purchase of all of the Mortgage Loans and each REO Property remaining in REMIC I by the Terminator, the Terminator shall deliver to the Trustee for deposit in the Distribution Account not later than the last Business Day preceding the final Distribution Date on the Certificates an amount in immediately available funds equal to the above-described purchase price. Upon certification to the Trustee by a Servicing Officer of the making of such final deposit, the Trustee shall promptly release or cause to be released to the Terminator the Mortgage Files for the remaining Mortgage Loans, and the Trustee shall execute all assignments, endorsements and other instruments necessary to effectuate such transfer.

(d)        Upon presentation of the Certificates by the Certificateholders on the final Distribution Date, the Trustee shall distribute to each Certificateholder so presenting and surrendering its Certificates the amount otherwise distributable on such Distribution Date in accordance with Section 4.01 in respect of the Certificates so presented and surrendered. Any funds not distributed to any Holder or Holders of Certificates being retired on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held in trust by the Trustee and credited to the account of the appropriate

non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section 9.01 shall not have been surrendered for cancellation within six months after the time specified in such notice, the Trustee shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Trustee shall, directly or through an agent, mail a final notice to remaining related non-tendering Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in the trust funds. If within one year after the final notice any such Certificates shall not have been surrendered for cancellation, the Trustee shall pay to the Underwriters all remaining amounts, and all rights of non-tendering Certificateholders in or to such amounts shall thereupon cease. No interest shall accrue or be payable to any Certificateholder on any amount held in trust by the Trustee as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 9.01.

Immediately following the deposit of funds in trust hereunder in respect of the Certificates, the Trust Fund shall terminate.

SECTION 9.02. Additional Termination Requirements.

(a)        In the event that the Terminator purchases all the Mortgage Loans and each REO Property or the final payment on or other liquidation of the last Mortgage Loan or REO Property remaining in REMIC I pursuant to Section 9.01, the Trust Fund shall be terminated in accordance with the following additional requirements:

(i)         The Trustee shall specify the first day in the 90-day liquidation period in a statement attached to each Trust REMIC’s final Tax Return pursuant to Treasury regulation Section 1.860F-1 and shall satisfy all requirements of a qualified liquidation under Section 860F of the Code and any regulations thereunder, as evidenced by an Opinion of Counsel delivered to the Trustee, the NIMS Insurer and the Guarantor obtained at the expense of the Terminator;

(ii)         During 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 all of the assets of REMIC I to the Terminator for cash; and

(iii)        At the time of the making of the final payment on the Certificates, the Trustee shall distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand in the Trust Fund (other than cash retained to meet claims), and the Trust Fund shall terminate at that time.

(b)        At the expense of the applicable Terminator (or in the event of termination under Section 9.01(a)(ii), at the expense of the Trustee), the Trustee shall prepare or cause to be prepared the documentation required in connection with the adoption of a plan of liquidation of each Trust REMIC pursuant to this Section 9.02.

(c)        By their acceptance of Certificates, the Holders thereof hereby agree to authorize the Trustee to specify the 90-day liquidation period for each Trust REMIC which authorization shall be binding upon all successor Certificateholders.

The Trustee, as agent for each Trust REMIC’s tax matters person, shall (i) act on behalf of the Trust Fund in relation to any tax matter or controversy involving any Trust REMIC and (ii) represent after consultation with the Guarantor, the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto. The Holder of the largest Percentage Interest of each Class of Residual Certificates shall be designated, in the manner provided under Treasury regulations section 1.860F-4(d) and Treasury regulations section 301.6231(a)(7)-1, as the tax matters person of the related REMIC created hereunder.

The Trustee shall provide to the Guarantor, upon request, copies of all of the Tax Returns and other tax related information in respect of any REMIC created hereunder.

(e)        The Trustee shall perform on behalf of each Trust REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions or other compliance guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, as required by the Code, the REMIC Provisions or other such compliance guidance, the Trustee shall provide (i) to any Transferor of a Residual Certificate such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any Person who is not a Permitted Transferee, (ii) 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 and market discount or premium (using the Prepayment Assumption as required) and (iii) to the Internal Revenue Service the name, title, address and telephone number of the person who shall serve as the representative of each Trust REMIC.

(f)         The Trustee shall take such action and shall cause each REMIC created hereunder to take such action as shall be necessary to create or maintain the status thereof as a REMIC under the REMIC Provisions (and the Master Servicer shall assist it, to the extent reasonably requested by it). The Trustee shall not take any action, cause the Trust Fund to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of any Trust REMIC as a REMIC or (ii) result in the imposition of a tax upon the Trust Fund (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee, the Guarantor and the NIMS Insurer have received an Opinion of Counsel, addressed to the Trustee, the NIMS Insurer and the Guarantor (at the expense of the party seeking to take such action but in no event at the expense of the Trustee) to the effect that the contemplated action shall not, with respect to any Trust REMIC, endanger such status or result in the imposition of such a tax, nor shall the Master Servicer take or fail to take any action (whether or not authorized hereunder) as to which the Trustee, the

Guarantor and the NIMS Insurer 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. In addition, prior to taking any action with respect to any Trust REMIC or the respective assets of each, or causing any Trust REMIC to take any action, which is not contemplated under the terms of this Agreement, the Master Servicer shall consult with the Trustee, the NIMS Insurer, the Guarantor or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any Trust REMIC, and the Master Servicer shall not take any such action or cause any Trust REMIC to take any such action as to which the Trustee, the Guarantor or the NIMS Insurer has advised it in writing that an Adverse REMIC Event could occur. The Trustee, the Guarantor or the NIMS Insurer 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 permitted by this Agreement, but in no event shall such cost be an expense of the Trustee.

(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 the “net income from foreclosure property” of such REMIC as defined in Section 860G(c) of the Code, on any contributions to any such REMIC after the Startup Day therefor pursuant to Section 860G(d) of the Code, or any other tax is imposed by the Code or any applicable provisions of state or local tax laws, such tax shall be charged (i) to the Trustee pursuant to Section 10.03 hereof, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article X, (ii) to the Master Servicer pursuant to Section 10.03 hereof, if such tax arises out of or results from a breach by the Master Servicer of any of its obligations under Article III or this Article X, or otherwise (iii) against amounts on deposit in the Distribution Account and shall be paid by withdrawal therefrom.

(h)        On or before April 15^th of each calendar year, commencing April 15, 2006, the Trustee shall deliver to the Master Servicer, the NIMS Insurer, the Guarantor and each Rating Agency a Certificate from a Responsible Officer of the Trustee stating, without regard to any action taken by any party other than the Trustee, the Trustee’s compliance with this Article X.

(i)         The Trustee shall, for federal income tax purposes, maintain books and records with respect to each Trust REMIC on a calendar year and on an accrual basis.

(j)         Following the Startup Day, the Trustee shall not accept any contributions of assets to any Trust REMIC other than in connection with any Qualified Substitute Mortgage Loan delivered in accordance with Section 2.03 unless it shall have received an Opinion of Counsel to the effect that the inclusion of such assets in the Trust Fund shall not cause the related REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding or subject such REMIC to any tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances.

(k)        Neither the Trustee nor the Master Servicer shall enter into any arrangement by which any Trust REMIC shall receive a fee or other compensation for services nor permit any such REMIC to receive any income from assets other than the Mortgage Pool which are deemed to constitute “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.

SECTION 10.03. Master Servicer and Trustee Indemnification.

(a)        The Trustee agrees to indemnify the Trust Fund, the NIMS Insurer, the Depositor, the Guarantor 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, caused solely by the Trustee’s failure to act in accordance with its standard of care set forth in this Article X or any state, local or franchise taxes imposed upon the Trust as a result of the location of the Trustee.

(b)        The Master Servicer agrees to indemnify the Trust Fund, the Guarantor, the NIMS Insurer, the Depositor 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 or the Trustee, as a result of a breach of the Master Servicer’s covenants set forth in Article III or this Article X or any state, local or franchise taxes imposed upon the Trust as a result of the location of the Master Servicer or any subservicer.

SECTION 11.08. Article and Section References.

All article and section references used in this Agreement, unless otherwise provided, are to articles and sections in this Agreement.

SECTION 11.09. Grant of Security Interest.

It is the express intent of the parties hereto that the conveyance of the Mortgage Loans by the Depositor to the Trustee be, and be construed as, a sale of the Mortgage Loans by the Depositor and not a pledge of the Mortgage Loans by the Depositor to secure a debt or other obligation of the Depositor or the Seller. However, in the event that, notwithstanding the

aforementioned intent of the parties, the Mortgage Loans are held to be property of the Depositor or the Seller, then, (a) it is the express intent of the parties that such conveyance be deemed a pledge of the Mortgage Loans by the Depositor to the Trustee to secure a debt or other obligation of the Depositor or the Seller and (b)(1) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the Uniform Commercial Code as in effect from time to time in the State of New York; (2) the conveyance provided for in Section 2.01 hereof shall be deemed to be a grant by the Seller and the Depositor to the Trustee of a security interest in all of the Seller’s and the Depositor’s right, title and interest in and to the Mortgage Loans and all amounts payable to the Holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, including without limitation all amounts, other than investment earnings, from time to time held or invested in the Collection Account and the Distribution Account, whether in the form of cash, instruments, securities or other property; (3) the obligations secured by such security agreement shall be deemed to be all of the Depositor’s obligations under this Agreement, including the obligation to provide to the Certificateholders the benefits of this Agreement relating to the Mortgage Loans and the Trust Fund; and (4) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Trustee for the purpose of perfecting such security interest under applicable law. Accordingly, the Depositor hereby grants to the Trustee a security interest in the Mortgage Loans and all other property described in clause (2) of the preceding sentence, for the purpose of securing to the Trustee on behalf of the Certificateholders the performance by the Depositor of the obligations described in clause (3) of the preceding sentence. Notwithstanding the foregoing, the parties hereto intend the conveyance pursuant to Section 2.01 and the transfer pursuant to the Mortgage Loan Purchase Agreement to be a true, absolute and unconditional sale of the Mortgage Loans and assets constituting the Trust Fund by the Depositor to the Trustee.

SECTION 11.10. Third Party Rights.

The NIMS Insurer and the Swap Provider shall be third-party beneficiaries of this Agreement to the same extent as if they were parties hereto, and shall have the right to enforce the provisions of this Agreement. Without limiting the generality of the foregoing, provisions herein that refer to the “benefit” of Certificateholders or the “interests” of the Certificateholders or actions “for the benefit of” Certificateholders also include an implicit reference to the benefits or interests of the NIMS Insurer, if any.

IN WITNESS WHEREOF, the Depositor, the Master Servicer and the Trustee have caused their names to be signed hereto by their respective officers thereunto duly authorized, in each case as of the day and year first above written.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Trustee and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in REMIC I, and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement from REMIC I of all the Mortgage Loans and all property acquired in respect of such Mortgage Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase from REMIC I all the Mortgage Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Stated Principal Balance of the Mortgage Loans at the time of purchase being less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.

The recitals contained herein shall be taken as statements of the Depositor and the Trustee assumes no responsibility for their correctness.

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.

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 as provided in the Agreement, 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 the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same 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 of Certificates, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

The Depositor, the Master Servicer, the Trustee, the NIMS Insurer (if any) and the Certificate Registrar and any agent of the Depositor, the Master Servicer, the NIMS Insurer (if any) 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, the NIMS Insurer (if any), the Certificate Registrar or any such agent shall be affected by notice to the contrary.

The Agreement permits, but does not require, the party designated in the Agreement to purchase from REMIC I all the Mortgage Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Stated Principal Balance of the Mortgage Loans at the time of purchase being less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.

The recitals contained herein shall be taken as statements of the Depositor and the Trustee assumes no responsibility for their correctness.

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. As provided in the Agreement, withdrawals from the Collection Account and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Mortgage Loans.

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 this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Trustee as provided in the Agreement, 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

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same 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 of Certificates, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

The Depositor, the Master Servicer, the Trustee, the NIMS Insurer (if any) and the Certificate Registrar and any agent of the Depositor, the Master Servicer, the NIMS Insurer (if any) 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, the NIMS Insurer (if any), the Certificate Registrar or any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Trustee and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in REMIC I, and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement from REMIC I of all the Mortgage Loans and all property acquired in respect of such Mortgage Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase from REMIC I all the Mortgage Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Stated Principal Balance of the Mortgage Loans at the time of purchase being less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.

The recitals contained herein shall be taken as statements of the Depositor and the Trustee assumes no responsibility for their correctness.

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

This Certificate is one of a duly authorized issue of Certificates designated as Asset-Backed Pass-Through Certificates of the Series specified on the face hereof (herein called the “Certificates”) and representing a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.

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. As provided in the Agreement, withdrawals from the Collection Account and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Mortgage Loans.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the NIMS Insurer (if any), the Trustee and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the NIMS Insurer (if any) and the Trustee with the consent of the NIMS Insurer (if any) and the Holders of Certificates entitled to at least 66% of the Voting Rights.

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

No transfer of this Certificate shall be made unless the transfer is made pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “1933 Act”), and an effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification (other than in connection with (i) the initial transfer of any such Certificate by the Depositor to an affiliate of the Depositor, (ii) the transfer of any such Certificate to the issuer under the Indenture or the indenture trustee under the Indenture or (iii) a transfer of any such Certificate from the issuer under the Indenture or the indenture trustee under the Indenture to the Depositor or an Affiliate of the Depositor). In the event that such a transfer of this Certificate is to be made without registration or qualification, the Trustee and the Certificate Registrar shall require receipt of (i) if such transfer is purportedly being made in reliance upon Rule 144A under the 1933 Act, written certifications from the Holder of the Certificate desiring to effect the transfer, and from such Holder’s prospective transferee, substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in all other cases, an Opinion of Counsel satisfactory to it that such transfer may be made without such registration or qualification (which Opinion of Counsel shall not be an expense of the Trust Fund or of the Depositor, the Trustee or the Master Servicer in their respective capacities as such), together with copies of the written certification(s) of the Holder of the Certificate desiring to effect the transfer and/or such Holder’s prospective transferee upon which such Opinion of Counsel is based. None of the Depositor, the Certificate Registrar or the Trustee is obligated to register or qualify the Class of Certificates specified on the face hereof under the 1933 Act or any other securities law or to take any action not otherwise required under the Agreement to permit the transfer of such Certificates without registration or qualification. Any Holder desiring to effect a transfer of this Certificate shall be required to indemnify the Trustee, the Depositor, the Certificate Registrar and the Master Servicer 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 to a Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person using “Plan Assets” to acquire this Certificate shall be made except in accordance with Section 5.02(d) of the Agreement.

No service charge will be made for any such registration of transfer or exchange of Certificates, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

The Depositor, the Master Servicer, the Trustee, the NIMS Insurer (if any) and the Certificate Registrar and any agent of the Depositor, the Master Servicer, the NIMS Insurer (if any) 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,

the NIMS Insurer (if any), the Certificate Registrar or any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Trustee and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in REMIC I, and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement from REMIC I of all the Mortgage Loans and all property acquired in respect of such Mortgage Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase from REMIC I all the Mortgage Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Stated Principal Balance of the Mortgage Loans at the time of purchase being less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.

The recitals contained herein shall be taken as statements of the Depositor and the Trustee assumes no responsibility for their correctness.

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.

Any Holder desiring to effect a transfer of this Certificate shall be required to indemnify the Trustee, the Depositor, the Certificate Registrar and the Master Servicer 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 to a Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person using “Plan Assets” to acquire this Certificate shall be made except in accordance with Section 5.02(d) of the Agreement.

Prior to registration of any transfer, sale or other disposition of this Certificate, the proposed transferee shall provide to the Trustee (i) an affidavit to the effect that such transferee is any Person other than a Disqualified Organization or the agent (including a broker, nominee or middleman) of a Disqualified Organization, and (ii) a certificate that acknowledges that (A) the Class R Certificates have been designated as residual interests in three REMICs, (B) it will include in its income a pro rata share of the net income of the Trust Fund and that such income may be an “excess inclusion,” as defined in the Code, that, with certain exceptions, cannot be offset by other losses or benefits from any tax exemption, and (C) it expects to have the financial means to satisfy all of its tax obligations including those relating to holding the Class R Certificates. Notwithstanding the registration in the Certificate Register of any transfer, sale or other disposition of this Certificate to a Disqualified Organization or an agent (including a broker, nominee or middleman) of a Disqualified Organization, such registration shall be deemed to be of no legal force or effect whatsoever and such Person shall not be deemed to be a Certificateholder for any purpose, including, but not limited to, the receipt of distributions in respect of this Certificate.

The Holder of this Certificate, by its acceptance hereof, shall be deemed to have consented to the provisions of Section 5.02 of the Agreement and to any amendment of the Agreement deemed necessary by counsel of the Depositor to ensure that the transfer of this Certificate to any Person other than a Permitted Transferee or any other Person will not cause the Trust Fund to cease to qualify as a REMIC or cause the imposition of a tax upon the REMIC.

No service charge will be made for any such registration of transfer or exchange of Certificates, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

The Depositor, the Master Servicer, the Trustee, the NIMS Insurer (if any) and the Certificate Registrar and any agent of the Depositor, the Master Servicer, the NIMS Insurer (if any) 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, the NIMS Insurer (if any), the Certificate Registrar or any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Trustee and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in REMIC I, and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement from REMIC I of all the Mortgage Loans and all property acquired in respect of such Mortgage Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase from REMIC I all the Mortgage Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Stated Principal Balance of the Mortgage Loans at the time of purchase being less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date.

The recitals contained herein shall be taken as statements of the Depositor and the Trustee assumes no responsibility for their correctness.

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.

(d) [Reserved].

(e)          Transfer of Interest in Agreements. The Purchaser has the right to assign its interest under this Agreement, in whole or in part, to the Trustee, as may be required to effect the purposes of the Pooling and Servicing Agreement, without the consent of the Seller, and the assignee shall succeed to the rights and obligations hereunder of the Purchaser. Any expense

reasonably incurred by or on behalf of the Purchaser or the Trustee in connection with enforcing any obligations of the Seller under this Agreement shall be promptly reimbursed by the Seller.

(f)           Examination of Mortgage Files.

(48)        With respect to any Mortgage Loan originated on or after August 1, 2004, neither the related Mortgage nor the related Mortgage Note requires the borrower to submit to arbitration to resolve any dispute arising out of or relating in any way to the mortgage loan transaction.

(b)          The Seller hereby represents, warrants and covenants to the Purchaser, with respect to the Group I Mortgage Loans as of the Closing Date or as of such date specifically provided herein:

(1)                 Each Group I Mortgage Loan is in compliance with the anti-predatory lending eligibility for purchase requirements of Fannie Mae's Selling Guide;

(2)                 The methodology used in underwriting the extension of credit for each Group I Mortgage Loan employs objective mathematical principles which relate the Mortgagor's income, assets and liabilities to the proposed payment and such underwriting methodology does not rely on the extent of the Mortgagor's equity in the collateral as the principal determining factor in approving such credit extension. Such underwriting methodology confirmed that at the time of origination (application/approval) the Mortgagor had a reasonable ability to make timely payments on the Group I Mortgage Loan;

(3)                 With respect to any Group I Mortgage Loan that contains a provision permitting imposition of a charge upon a prepayment prior to maturity: (i) prior to the Group I Mortgage Loan's origination, the Mortgagor agreed to such charge in exchange for a monetary benefit, including but not limited to a rate or fee reduction, (ii) prior to the Group I Mortgage Loan's origination, the Mortgagor was offered the option of obtaining a mortgage loan that did not require payment of such a charge, (iii) the prepayment charge is disclosed to the Mortgagor in the loan documents pursuant to applicable state and federal law, (iv) for loans originated on or after September 1, 2004, the duration of the prepayment period shall not exceed three (3) years from the date of the Mortgage Note unless the loan was modified to reduce the prepayment period to no more than three years from the date of the Mortgage Note and the borrower was notified in writing of such reduction in the prepayment period, and (v) notwithstanding any state or federal law to the contrary, the Master Servicer shall not impose such prepayment charge in any instance when the mortgage debt is accelerated as the result of the Mortgagor's default in making the loan payments;

(4)                 All points and fees related to each Group I Mortgage Loan were disclosed in writing to the Mortgagor in accordance with applicable state and federal law and regulation. Except in the case of a Group I Mortgage Loan in an original principal amount of less than $60,000 which would have resulted in an unprofitable origination, no Mortgagor was charged “points and fees” (whether or not financed) in an amount greater than 5% of the principal amount of such loan and such 5% limitation is calculated in accordance with Fannie Mae's anti-predatory lending requirements as set forth in the Fannie Mae Selling Guide;

(5)                 All fees and charges (including finance charges) and whether or not financed, assessed, collected or to be collected in connection with the origination and servicing of each Group I Mortgage Loan have been disclosed in writing to the Mortgagor in accordance with applicable state and federal law and regulation;

(6)                 No Group I Mortgage Loan Mortgagor was encouraged or required to select a mortgage loan product offered by the Originator which is a higher cost product designed for a less creditworthy Mortgagor, unless at the time of the Group I Mortgage Loan's origination, such Mortgagor did not qualify taking into account credit history and debt-to-income ratios for a lower-cost credit product then offered by the Originator;

(7)                 Each Group I Mortgage Loan meets the representations, warranties and covenants set forth in Exhibit A to the letter from Fannie Mae dated August 10, 2005, which sets forth the conditions to Fannie Mae’s participation as guarantor in the Series 2005-R7 transaction;

(8)                 No Group I Mortgage Loan is a “High Cost Home Loan” as defined in New York Banking Law 6-1;

(9)                 No Group I Mortgage Loan is a “High-Cost Home Loan” as defined in the Arkansas Home Loan Protection Act, effective as of July 16, 2003;

(10)               No Group I Mortgage Loan is a “High-Cost Home Loan” as defined in Kentucky State Statute KRS 360.100, effective as of June 24, 2003;

(11)               No Group I Mortgage Loan is a “High-Cost Home Loan” as defined in the New Jersey Home Ownership Act, effective as of November 27, 2003;

(12)               No Group I Mortgage Loan is a “High-Cost Home Loan” as defined in the New Mexico Home Loan Protection Act, effective as of January 1, 2004;

(13)               No Group I Mortgage Loan is a “High-Risk Home Loan” as defined in the Illinois High-Risk Home Loan Act, effective as of January 1, 2004;

(14)               No Group I Mortgage Loan is a “High-Cost Home Mortgage Loan” as defined in the Massachusetts Predatory Home Loan Practices Act, effective November 7, 2004 (Mass. Ann. Laws Ch. 183C);

(15)               No Group I Mortgage Loan is a “High Cost Home Loan” as defined in the Indiana Home Loan Practices Act, effective January 1, 2005 (Ind. Code Ann. Sections 24-9-1 through 24-9-9);

(16)               No Group I Mortgage Loan is a balloon mortgage loan that has an original stated maturity of less than seven (7) years; and

(17)               No Mortgagor was required to purchase any single premium credit insurance policy (e.g., life, mortgage, disability, accident, unemployment, or health insurance product) or debt cancellation agreement as a condition of obtaining the extension of credit. No Mortgagor obtained a prepaid single-premium credit insurance policy (e.g., life, mortgage, disability, accident, unemployment, or health insurance product) in connection with the origination of such Group I Mortgage Loan. No proceeds from any Group I Mortgage Loan were used to purchase single premium credit insurance policies or debt cancellation agreements as part of the origination of, or as a condition to closing, such Group I Mortgage Loan.

SECTION 7. Repurchase Obligation for Defective Documentation and for Breach of Representation and Warranty.

(a)          The representations and warranties contained in Section 6 shall not be impaired by any review and examination of loan files or other documents evidencing or relating

to the Mortgage Loans or any failure on the part of the Purchaser to review or examine such documents and shall inure to the benefit of any assignee, transferee or designee of the Purchaser, including the Trustee for the benefit of the Certificateholders.

Upon discovery by the Seller, the Purchaser or any assignee, transferee or designee of the Purchaser of any materially defective document in, or that any material document was not transferred by the Seller (as listed on the Trustee’s Preliminary Exception Report) as part of, any Mortgage File or of a breach of any of the representations and warranties contained in Section 5 or Section 6 that materially and adversely affects the value of any Mortgage Loan or the interest therein of the Purchaser or the Purchaser’s assignee, transferee or designee (it being understood that with respect to the representations and warranties set forth in (39), (40), (41), (42), (43), (44), (46), (47) and (48) of Section 6(a) herein, a breach of any such representation or warranty shall in and of itself be deemed to materially adversely affect the interest therein of the Purchaser and the Purchaser’s assignee, transferee or designee), the party discovering the breach shall give prompt written notice to the other. Within ninety (90) days of its discovery or its receipt of notice of any such missing documentation which was not transferred to the Purchaser as described above or materially defective documentation or any such breach of a representation and warranty (it being understood that with respect to the representations and warranties set forth in (39), (40), (41), (42), (43), (44), (46), (47) and (48) of Section 6(a) herein, a breach of any such representation or warranty shall in and of itself be deemed to materially adversely affect the interest therein of the Purchaser and the Purchaser’s assignee, transferee or designee), the Seller promptly shall deliver such missing document or cure such defect or breach in all material respects, or in the event the Seller cannot deliver such missing document or such defect or breach cannot be cured, the Seller shall, within ninety (90) days of its discovery or receipt of notice, either (i) repurchase the affected Mortgage Loan at a price equal to the Purchase Price or (ii) pursuant to the provisions of the Pooling and Servicing Agreement, cause the removal of such Mortgage Loan from the Trust Fund and substitute one or more Qualified Substitute Mortgage Loans. In the event that any Mortgage Loan is subject to a breach of the representation and warranty in Section 6(a)(37) or (45) resulting in the Master Servicer’s inability to collect all or part of the Prepayment Charge from the Mortgagor, in lieu of repurchase, the Seller shall be obligated to remit to the Master Servicer (for deposit in the Collection Account) any shortfall in the Prepayment Charge collected upon the Mortgagor’s voluntary Principal Prepayment.

Notwithstanding the foregoing, within ninety (90) days of the earlier of discovery by the Seller or receipt of notice by the Seller of the breach of the representation of the Seller set forth in Section 6(a)(37) or (45) above, which materially and adversely affects the interests of the Holders of the Class P Certificates in any Prepayment Charge, the Seller shall pay the amount of the scheduled Prepayment Charge, for the benefit of the Holders of the Class P Certificates, by depositing such amount into the Collection Account, net of any amount previously collected by the Master Servicer and paid by the Master Servicer, for the benefit of the Holders of the Class P Certificates, in respect of such Prepayment Charge.

The Seller shall amend the Closing Schedule to reflect the withdrawal of such Mortgage Loan from the terms of this Agreement and the Pooling and Servicing Agreement and the addition, if any, of a Qualified Substitute Mortgage Loan. The Seller shall deliver to the Purchaser such amended Closing Schedule and shall deliver such other documents as are required by this Agreement or the Pooling and Servicing Agreement within five (5) days of any

such amendment. Any repurchase pursuant to this Section 7(a) shall be accomplished by deposit in the Collection Account of the amount of the Purchase Price in accordance with Section 2.03 of the Pooling and Servicing Agreement. Any repurchase or substitution required by this Section shall be made in a manner consistent with Section 2.03 of the Pooling and Servicing Agreement.

In addition, upon discovery by the Seller, the Purchaser, or any assignee, transferee or designee of the Purchaser that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering the breach shall give prompt written notice within five (5) Business Days to the others. Within ninety (90) days of its discovery or its receipt of notice, the Seller promptly shall either (i) repurchase the affected Mortgage Loan at the Purchase Price (as such term is defined in the Pooling and Servicing Agreement) or (ii) pursuant to the provisions of the Pooling and Servicing Agreement, cause the removal of such Mortgage Loan from the Trust Fund and substitute one or more Qualified Substitute Mortgage Loans.

(b)          It is understood and agreed that the obligations of the Seller set forth in this Section 7 to cure, remit a Prepayment Charge shortfall, repurchase or substitute for a defective Mortgage Loan constitute the sole remedies of the Purchaser against the Seller respecting a missing or defective material document or a breach of the representations and warranties contained in Section 5 or Section 6.

SECTION 8.            Closing; Payment for the Mortgage Loans. The closing of the purchase and sale of the Mortgage Loans shall be held at the New York City office of Thacher Proffitt & Wood LLP at 10:00 AM New York City time on the Closing Date.

The closing shall be subject to each of the following conditions:

(a) All of the representations and warranties of the Seller under this Agreement shall be true and correct in all material respects as of the date as of which they are made and no event shall have occurred which, with notice or the passage of time, would constitute a default under this Agreement;

(b) The Purchaser shall have received, or the attorneys of the Purchaser shall have received in escrow (to be released from escrow at the time of closing), all Closing Documents as specified in Section 9 of this Agreement, in such forms as are agreed upon and acceptable to the Purchaser, duly executed by all signatories other than the Purchaser as required pursuant to the respective terms thereof;

(c) The Seller shall have delivered or caused to be delivered and released to the Purchaser or to its designee, all documents (including without limitation, the Mortgage Loans) required to be so delivered by the

Purchaser pursuant to Section 2.01 of the Pooling and Servicing Agreement; and

(d) All other terms and conditions of this Agreement shall have been complied with.

Subject to the foregoing conditions, the Purchaser shall deliver or cause to be delivered to the Seller on the Closing Date, against delivery and release by the Seller to the Trustee of all documents required pursuant to the Pooling and Servicing Agreement, the consideration for the Mortgage Loans as specified in Section 3 of this Agreement, by delivery to the Seller of the purchase price.

SECTION 9.            Closing Documents. Without limiting the generality of Section 8 hereof, the closing shall be subject to delivery of each of the following documents:

(d) Such opinions of counsel from the Purchaser’s or Seller’s counsel as the Rating Agencies or the Guarantor may request in connection with the sale

of the Mortgage Loans by the Seller to the Purchaser or the Seller’s execution and delivery of, or performance under, this Agreement and upon which the Underwriters may rely;

(e) [Reserved];

(f) A letter from Ernst & Young, certified public accountants, dated the date hereof and to the effect that they have performed certain specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature set forth in the Prospectus Supplement, under the captions “Summary of Prospectus Supplement”, “Risk Factors”, “The Mortgage Pool”, “Yield on the Certificates”, “Description of the Certificates”, “Pooling and Servicing Agreement—The Seller and the Master Servicer”, Annex II and Annex III agrees with the records of the Seller and the Master Servicer;

(g) [Reserved];

(h) The Seller and the Master Servicer shall deliver for inclusion in the Prospectus Supplement and Information Circular, under the captions “The Mortgage Pool—Underwriting Standards of the Originator” and “Pooling and Servicing Agreement—The Seller and Master Servicer,” or for inclusion in other offering material, such publicly available information regarding its financial condition and its mortgage loan delinquency, foreclosure and loss experience, underwriting standards, lending activities and loan sales, production, and servicing and collection practices, and any similar nonpublic, unaudited financial information;

(i) [Reserved];

(j) Such further information, certificates, opinions and documents as the Purchaser or the Underwriters may reasonably request.

SECTION 10.          Costs. The Seller shall pay (or shall reimburse the Purchaser or any other Person to the extent that the Purchaser or such other Person shall pay) all costs and expenses incurred in connection with the transfer and delivery of the Mortgage Loans, including without limitation, assignment of mortgage recording costs and/or fees for title policy endorsements and continuations, the fees and expenses of the Seller’s in-house accountants and in-house attorneys, the costs and expenses incurred in connection with producing the Seller’s loan loss, foreclosure and delinquency experience, and the costs and expenses incurred in connection with obtaining the documents referred to in Sections 9(d) and 9(f) to the extent such

SECTION 11.	[Reserved].
SECTION 12.	[Reserved].

SECTION 13.         Mandatory Delivery; Grant of Security Interest. The sale and delivery on the Closing Date of the Mortgage Loans described on the Mortgage Loan Schedule in accordance with the terms and conditions of this Agreement is mandatory. It is specifically understood and agreed that each Mortgage Loan is unique and identifiable on the date hereof and that an award of money damages would be insufficient to compensate the Purchaser for the losses and damages incurred by the Purchaser in the event of the Seller’s failure to deliver the Mortgage Loans on or before the Closing Date. The Seller hereby grants to the Purchaser a lien on and a continuing security interest in the Seller’s interest in each Mortgage Loan and each document and instrument evidencing each such Mortgage Loan to secure the performance by the Seller of its obligation hereunder, and the Seller agrees that it holds such Mortgage Loans in custody for the Purchaser, subject to the Purchaser’s (i) right, prior to the Closing Date, to reject any Mortgage Loan to the extent permitted by this Agreement and (ii) obligation to deliver or cause to be delivered the consideration for the Mortgage Loans pursuant to Section 8 hereof. Any Mortgage Loans rejected by the Purchaser shall concurrently therewith be released from the security interest created hereby. The Seller agrees that, upon acceptance of the Mortgage Loans by the Purchaser or its designee and delivery of payment to the Seller, that its security interest in the Mortgage Loans shall be released. All rights and remedies of the Purchaser under this Agreement are distinct from, and cumulative with, any other rights or remedies under this Agreement or afforded by law or equity and all such rights and remedies may be exercised concurrently, independently or successively.

Notwithstanding the foregoing, if on the Closing Date, each of the conditions set forth in Section 8 hereof shall have been satisfied and the Purchaser shall not have paid or caused to be paid the purchase price, or any such condition shall not have been waived or satisfied and the Purchaser determines not to pay or cause to be paid the purchase price, the Purchaser shall

immediately effect the redelivery of the Mortgage Loans, if delivery to the Purchaser has occurred and the security interest created by this Section 13 shall be deemed to have been released.

SECTION 14.          Notices. All demands, notices and communications hereunder shall be in writing and shall be deemed to have been duly given if personally delivered to or mailed by registered mail, postage prepaid, or transmitted by telex or telegraph and confirmed by a similar mailed writing, if to the Purchaser, addressed to the Purchaser at 1100 Town & Country Road, Suite 1100, Orange, California 92868, Facsimile: (714) 564-9639, Attention: General Counsel, or such other address as may hereafter be furnished to the Seller in writing by the Purchaser; if to the Seller, addressed to the Seller at 1100 Town & Country Road, Suite 1100, Orange, California 92868, Facsimile: (714) 564-9639, Attention: General Counsel, or to such other address as the Seller may designate in writing to the Purchaser.

SECTION 15.          Severability of Provisions. Any part, provision, representation or warranty of this Agreement which is prohibited or which is held to be void or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof. Any part, provision, representation or warranty of this Agreement which is prohibited or unenforceable or is held to be void or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction as to any Mortgage Loan shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereto waive any provision of law which prohibits or renders void or unenforceable any provision hereof.

SECTION 16.         Agreement of Parties. The Seller and the Purchaser agree to execute and deliver such instruments and take such actions as either may, from time to time, reasonably request in order to effectuate the purpose and to carry out the terms of this Agreement and the Pooling and Servicing Agreement.

SECTION 17.          Survival. The Seller agrees that the representations, warranties and agreements made by it herein and in any certificate or other instrument delivered pursuant hereto shall be deemed to be relied upon by the Purchaser, notwithstanding any investigation heretofore or hereafter made by the Purchaser or on its behalf, and that the representations, warranties and agreements made by the Seller herein or in any such certificate or other instrument shall survive the delivery of and payment for the Mortgage Loans and shall continue in full force and effect, notwithstanding any restrictive or qualified endorsement on the Mortgage Notes and notwithstanding subsequent termination of this Agreement, the Pooling and Servicing Agreement or the Trust Fund.

SECTION 18.        GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS, DUTIES, OBLIGATIONS AND RESPONSIBILITIES OF THE PARTIES

HERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS AND DECISIONS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCPLES OF CONFLICTS OF LAW OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW WHICH SHALL GOVERN.

SECTION 19.         Miscellaneous. This Agreement may be executed in two or more counterparts, each of which when so executed and delivered shall be an original, but all of which together shall constitute one and the same instrument. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns. This Agreement supersedes all prior agreements and understandings relating to the subject matter hereof. Neither this Agreement nor any term hereof may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought. The headings in this Agreement are for purposes of reference only and shall not limit or otherwise affect the meaning hereof. Each of the NIMS Insurer, if any, and the Guarantor shall be a third-party beneficiary hereof and may enforce the terms hereof as if a party hereto.

It is the express intent of the parties hereto that the conveyance of the Mortgage Loans by the Seller to the Purchaser as provided in Section 4 hereof be, and be construed as, a sale of the Mortgage Loans by the Seller to the Purchaser and not as a pledge of the Mortgage Loans by the Seller to the Purchaser to secure a debt or other obligation of the Seller. However, in the event that, notwithstanding the aforementioned intent of the parties, the Mortgage Loans are held to be property of the Seller, then, (a) it is the express intent of the parties that such conveyance be deemed a pledge of the Mortgage Loans by the Seller to the Purchaser to secure a debt or other obligation of the Seller and (b) (1) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the New York Uniform Commercial Code; (2) the conveyance provided for in Section 4 hereof shall be deemed to be a grant by the Seller to the Purchaser of a security interest in all of the Seller’s right, title and interest in and to the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, including without limitation all amounts, other than investment earnings, from time to time held or invested in the Collection Account whether in the form of cash, instruments, securities or other property; (3) the possession by the Purchaser or its agent of Mortgage Notes, the related Mortgages and such other items of property that constitute instruments, money, negotiable documents or chattel paper shall be deemed to be “possession” for purposes of perfecting the security interest pursuant to the New York Uniform Commercial Code; and (4) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Purchaser for the purpose of perfecting such security interest under applicable law. The Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement and the Pooling and Servicing Agreement.

SECTION 20.        Obligations of ACC Capital Holdings Corporation. ACC Capital Holdings Corporation (“ACCH”) agrees with the Purchaser and any assignee of the Purchaser as follows: as an inducement to the Purchaser’s agreement to purchase the Mortgage Loans from the Seller, to indemnify and hold harmless the Purchaser and any assignee of the Purchaser against any failure by the Seller to repurchase or substitute for any Mortgage Loan pursuant to Section 7 hereof; provided, however, ACCH may at any time terminate its obligations pursuant to this Section 20 so long as it receives written confirmation from the Rating Agencies that such termination would not result in a withdrawal or a downgrade by any Rating Agency of the rating on any Class of Certificates.

IN WITNESS WHEREOF, the Seller and the Purchaser have caused their names to be signed by their respective officers thereunto duly authorized as of the date first above written.

FORM OF TRANSFER AFFIDAVIT AND AGREEMENT

STATE OF NEW YORK	)
	)	ss.:
COUNTY OF NEW YORK	)

The undersigned, being first duly sworn, deposes and says as follows:

1.The undersigned is an officer of ________________________, the proposed Transferee of an Ownership Interest in a Residual Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement, dated as of August 1, 2005 (the “Agreement”), among Ameriquest Mortgage Securities Inc., as depositor (the “Depositor”), Ameriquest Mortgage Company, as master servicer (the “Servicer”), Federal National Mortgage Association, as guarantor of the Group I Certificates, and Deutsche Bank National Trust Company, as trustee (the “Trustee”). Capitalized terms used, but not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee for the benefit of the Depositor and the Trustee.

2.The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest in the Certificate for its own account. The Transferee has no knowledge that any such affidavit is false.

3.The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are not Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is a Permitted Transferee and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false.

4.The Transferee has been advised of, and understands that a tax will be imposed on a “pass-through entity” holding the Certificate if at any time during the taxable year of the pass-through entity a Person that is not a Permitted Transferee is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is a Permitted Transferee and the pass-through entity does not have actual knowledge that such affidavit is false. (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 and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.)

5.The Transferee has reviewed the provisions of Section 5.02(d) of the Agreement and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 5.02(d) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

6.The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and in connection with any Transfer by a Person for whom the Transferee is acting as nominee, trustee or agent, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a certificate substantially in the form set forth as Exhibit L to the Agreement (a “Transferor Certificate”) to the effect that such Transferee has no actual knowledge that the Person to which the Transfer is to be made is not a Permitted Transferee.

7.The Transferee has historically paid its debts as they have come due, intends to pay its debts as they come due in the future, and understands that the taxes payable with respect to the Certificate may exceed the cash flow with respect thereto in some or all periods and intends to pay such taxes as they become due. The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Certificate.

8.	The Transferee’s taxpayer identification number is ___________.
9.	The Transferee is a U.S. Person as defined in Code Section 7701(a)(30).

10.The Transferee is aware that the Certificate may be a “noneconomic residual interest” within the meaning of proposed 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.

11.The Transferee will not cause income from the Certificate to be attributable to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of the Transferee or any other U.S. person.

12. Check one of the following:

[ ]  The present value of the anticipated tax liabilities associated with holding the Certificate, as applicable, does not exceed the sum of:

(i) the present value of any consideration given to the Transferee to acquire such Certificate;

(ii) the present value of the expected future distributions on such Certificate; and

(iii) the present value of the anticipated tax savings associated with holding such Certificate as the related REMIC generates losses.

For purposes of this calculation, (i) the Transferee is assumed to pay tax at the highest rate currently specified in Section 11(b) of the Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in Section 11(b) of the Code if the Transferee has been subject to the alternative minimum tax under Section 55 of the Code in the preceding two years and will compute its taxable income in the current taxable year using the alternative minimum tax rate) and (ii) present values are computed using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d) of the Code for the month of the transfer and the compounding period used by the Transferee.

[ ]  The transfer of the Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

(i) the Transferee is an “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to which income from the Certificate will only be taxed in the United States;

(ii) at the time of the transfer, and at the close of the Transferee’s two fiscal years preceding the year of the transfer, the Transferee had gross assets for financial reporting purposes (excluding any obligation of a person related to the Transferee within the meaning of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;

(iii) the Transferee will transfer the Certificate only to another “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of Sections 1.860E-1(c)(4)(i), (ii) and (iii) and Section 1.860E-1(c)(5) of the U.S. Treasury Regulations; and

(iv) the Transferee determined the consideration paid to it to acquire the Certificate based on reasonable market assumptions (including, but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax rates and other factors specific to the Transferee) that it has determined in good faith.

[ ]  None of the above.

13.The Transferee is not an employee benefit plan that is subject to Title I of ERISA or a plan that is subject to Section 4975 of the Code or a plan subject to any Federal, state or local law that is substantially similar to Title I of ERISA or Section 4975 of the Code, and the Transferee is not acting on behalf of or investing plan assets of such a plan.

IN WITNESS WHEREOF, the Transferee has caused this instrument to be executed on its behalf, pursuant to authority of its Board of Directors, by its duly authorized officer and its corporate seal to be hereunto affixed, duly attested, this day of , 20.

(i)The Swap Administrator shall have the full power and authority to do all things not inconsistent with the provisions of this Agreement that it may deem advisable in order to enforce the provisions hereof. The Swap Administrator shall not be answerable or accountable except for its own bad faith, willful misconduct or negligence. The Swap Administrator shall not be required to take any action to exercise or enforce any of its rights or powers hereunder which, in the opinion of the Swap Administrator, shall be likely to involve expense or liability to the Swap Administrator, unless the Swap Administrator shall have received an agreement satisfactory to it in its sole discretion to indemnify it against such liability and expense.

(ii)The Swap Administrator shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of any party hereto or the NIMS Insurer or otherwise as provided herein, relating to the time, method and place of conducting any proceeding for any remedy available to the Swap Administrator or exercising any right or power conferred upon the Swap Administrator under this Agreement.

(iii)The Swap Administrator may perform any duties hereunder either directly or by or through agents or attorneys of the Swap Administrator. The Swap Administrator shall not be liable for the acts or omissions of its agents or attorneys so long as the Swap Administrator chose such Persons with due care.

3.Swap Administration Account. The Swap Administrator shall segregate and hold all funds received pursuant to the Swap Agreement (including any Swap Termination Payment) separate and apart from any of its own funds and general assets and shall establish and maintain in the name of the Swap Administrator one or more segregated accounts (such account or accounts, the “Swap Administration Account”), held in trust for the benefit of the Trustee, the

Indenture Trustee and the parties to this Agreement. All amounts on deposit in the Swap Administration Account shall remain uninvested unless the Swap Administrator receives instructions to the contrary from any party hereto, with the consent of the NIMS Insurer. The Swap Administrator hereby agrees that it holds and shall hold the Swap Administration Account and all amounts deposited therein in trust for the exclusive use and benefit of the Trustee and the Indenture Trustee as their interests may appear.

4. Replacement Swap Agreements.

The Trustee shall, at the direction of the NIMS Insurer or, with the consent of the NIMS Insurer, at the direction of Ameriquest, enforce all of its rights and exercise any remedies under the Swap Agreement and, in the event the Swap Agreement is terminated as a result of the designation by either party thereto of an Early Termination Date (as defined therein), find a replacement counterparty to enter into a replacement swap agreement.

Any Swap Termination Payment received by the Swap Administrator shall be deposited in the Swap Administration Account and shall be used to make any upfront payment required under a replacement swap agreement and any upfront payment received from the counterparty to a replacement swap agreement shall be used to pay any Swap Termination Payment owed to the Swap Provider.

Notwithstanding anything contained herein, in the event that a replacement swap agreement cannot be obtained within 30 days after receipt by the Swap Administrator of the Swap Termination Payment paid by the terminated Swap Provider, the Swap Administrator shall deposit such Swap Termination Payment into a separate, non-interest bearing account established by the Swap Administrator and the Swap Administrator shall, on each Distribution Date following receipt of such Swap Termination Payment, withdraw from such account, an amount equal to the Net Swap Payment, if any, that would have been paid to the Trust by the original Swap Provider (computed in accordance with Section 2 of the original Swap Agreement attached hereto as Exhibit A) and distribute such amount in accordance with Section 2(a) of this Agreement. On the Distribution Date immediately after the termination date of the original Swap Agreement, the Swap Administrator shall withdraw any funds remaining in such account and distribute such amount in accordance with Section 2(a)(ii) of this Agreement.

5.Representations and Warranties of Deutsche Bank National Trust Company. Deutsche Bank National Trust Company represents and warrants as follows:

(a)Deutsche Bank National Trust Company is duly organized and validly existing as a national banking association under the laws of the United States and has all requisite power and authority to execute and deliver this Agreement, to perform its obligations as Swap Administrator hereunder.

(b)The execution, delivery and performance of this Agreement by Deutsche Bank National Trust Company as Swap Administrator and Trustee have been duly authorized in the Pooling and Servicing Agreement and the Indenture.

(c)This Agreement has been duly executed and delivered by Deutsche Bank National Trust Company as Swap Administrator and Trustee and is enforceable against Deutsche Bank

National Trust Company in such capacities in accordance with its terms, except as enforceability may be affected by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law).

6. Replacement of Swap Administrator.

Any corporation, bank, trust company or association into which the Swap Administrator may be merged or converted or with which it may be consolidated, or any corporation, bank, trust company or association resulting from any merger, conversion or consolidation to which the Swap Administrator shall be a party, or any corporation, bank, trust company or association succeeding to all or substantially all the corporate trust business of the Swap Administrator, shall be the successor of the Swap Administrator hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, except to the extent that assumption of its duties and obligations, as such, is not effected by operation of law.

No resignation or removal of the Swap Administrator and no appointment of a successor Swap Administrator shall become effective until the appointment by Ameriquest of a successor swap administrator acceptable to the NIMS Insurer. Any successor swap administrator shall execute such documents or instruments necessary or appropriate to vest in and confirm to such successor swap administrator all such rights and powers conferred by this Agreement.

The Swap Administrator may resign at any time by giving written notice thereof to the other parties hereto with a copy to the NIMS Insurer. If a successor swap administrator shall not have accepted the appointment hereunder within 30 days after the giving by the resigning Swap Administrator of such notice of resignation, the resigning Swap Administrator may petition any court of competent jurisdiction for the appointment of a successor swap administrator acceptable to the NIMS Insurer.

In the event of a resignation or removal of the Swap Administrator, Ameriquest shall promptly appoint a successor Swap Administrator acceptable to the NIMS Insurer. If no such appointment has been made within 10 days of the resignation or removal, the NIMS Insurer may appoint a successor Swap Administrator.

7. Trustee Obligations.

Whenever the Trustee, as a party to the Swap Agreement, has the option or is requested in such capacity, whether such request is by the counterparty to such agreement, to take any action or to give any consent, approval or waiver that it is entitled to take or give in such capacity, including, without limitation, in connection with an amendment of such agreement or the occurrence of a default or termination event thereunder, the Trustee shall promptly notify the parties hereto and the NIMS Insurer of such request in such detail as is available to it and, shall, on behalf of the parties hereto and the NIMS Insurer, take such action in connection with the exercise and/or enforcement of any rights and/or remedies available to it in such capacity with respect to such request as the NIMS Insurer shall direct in writing; provided that if no such direction is received prior to the date that is established for taking such action or

giving such consent, approval or waiver (notice of which date shall be given by the Trustee to the parties hereto and the NIMS Insurer), the Trustee may abstain from taking such action or giving such consent, approval or waiver.

The Trustee shall forward to the parties hereto and the NIMS Insurer on the Payment Date following its receipt thereof copies of any and all notices, statements, reports and/or other material communications and information (collectively, the “Swap Reports”) that it receives in connection with the Swap Agreement or from the counterparty thereto.

8. Miscellaneous.

(a)This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

(b)Any action or proceeding against any of the parties hereto relating in any way to this Agreement may be brought and enforced in the courts of the State of New York sitting in the borough of Manhattan or of the United States District Court for the Southern District of New York, and the Swap Administrator irrevocably submits to the jurisdiction of each such court in respect of any such action or proceeding.

(e)This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by facsimile transmission), and all such counterparts taken together shall be deemed to constitute one and the same instrument.

(f)Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

(g)The representations and warranties made by the parties to this Agreement shall survive the execution and delivery of this Agreement. No act or omission on the part of any party hereto shall constitute a waiver of any such representation or warranty.

(h)The article and section headings herein are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

9.Third-Party Beneficiary. Each of the Note Insurer, the Backup Note Insurer and the Indenture Trustee shall be deemed a third-party beneficiary of this Agreement to the same extent as if it were a party hereto and shall have the right to enforce the provisions of this Agreement.

10.Swap Administrator Rights. The Swap Administrator shall be entitled to the same rights, protections and indemnities afforded to the Trustee under the Pooling and Servicing Agreement and the Indenture Trustee under the Indenture, in each case, as if specifically set forth herein with respect to the Swap Administrator.

11.Limited Recourse. Notwithstanding any other provisions of this Agreement, the obligations of the Trustee under this Agreement are limited recourse obligations of the Trustee. Such obligations are non-recourse to the Trustee, its assets and its property other than the assets of the Trust Fund, and following realization of such assets, any claims of any party hereto shall be extinguished and shall not thereafter be reinstated. No recourse shall be had against any principal, director, officer, employee, beneficiary, shareholder, partner, member, trustee, agent or affiliate of the Trustee or any person owning, directly or indirectly, any legal or beneficial interest in the Trustee, or any successors or assigns of any of the foregoing (the “Exculpated Parties”) for the payment of any amount payable under this Agreement.

The agreements in this paragraph shall survive termination of this Agreement and the performance of all obligations hereunder.

IN WITNESS WHEREOF, the parties have caused this Agreement to be duly executed and delivered as of the day and year first above written.
