This TRUST AGREEMENT, dated as of August 1, 2004 (the “Agreement”), is by and among STRUCTURED ASSET SECURITIES CORPORATION, a Delaware corporation, as depositor (the “Depositor”), AURORA LOAN SERVICES INC., as master servicer (the “Master Servicer”), and CITIBANK, N.A., as trustee (the “Trustee”).

PRELIMINARY STATEMENT

The Depositor has acquired the Mortgage Loans from Xxxxxx Brothers Holdings Inc. (the “Seller”) and at the Closing Date is the owner of the Mortgage Loans and the other property being conveyed by it to the Trustee for inclusion in the Trust Fund. On the Closing Date, the Depositor will acquire the Certificates from the Trust Fund, as consideration for its transfer to the Trust Fund of the Mortgage Loans and the other property constituting the Trust Fund. The Depositor has duly authorized the execution and delivery of this Agreement to provide for the conveyance to the Trustee of the Mortgage Loans and the other property constituting the Trust Fund. All covenants and agreements made by the Depositor, the Master Servicer and the Trustee herein with respect to the Mortgage Loans and the other property constituting the Trust Fund are for the benefit of the Holders from time to time of the Certificates. The Depositor and the Master Servicer are entering into this Agreement, and the Trustee is accepting the Trust Fund created hereby, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.

As provided herein, the Trustee shall elect that the Trust Fund (exclusive of amounts payable in respect of the Class E and Class P Certificates) be treated for federal income tax purposes as comprising three real estate mortgage investment conduits (each a “REMIC” or, in the alternative, REMIC I, REMIC II, and REMIC III, respectively). Each Certificate, other than the Class E, Class P or Class R Certificate, represents ownership of one or more regular interests in REMIC III for purposes of the REMIC Provisions. The Class P and Class E Certificates will represent interests in the Trust Fund but are not interests in any REMIC created hereunder. The Class R Certificate represents ownership of the sole class of residual interest in REMIC I, REMIC II, and REMIC III for purposes of the REMIC Provisions.

REMIC I

REMIC I shall hold as assets all property of the Trust Fund other than the Interests in REMIC I and REMIC II, the Class P Distributable Amount, which is beneficially owned by the holder of the Class P Certificate, and the Class E Distributable Amount, which is beneficially owned by the holder of the Class E Certificate. REMIC I shall issue the several classes of uncertificated REMIC I Interests set out below. Each such REMIC I Interest, other than the Class R-1 Interest, is hereby designated as a regular interest in REMIC I. The following table specifies the Class designation, interest rate, and principal amount for each Class of REMIC I Interests:

Section 2.02. Acceptance of Trust Fund by Trustee: Review of Documentation for Trust Fund.

(a) The Trustee, by execution and delivery hereof, acknowledges receipt by it or a Custodian on behalf of the Trustee, of the Mortgage Files pertaining to the Mortgage Loans listed on the Mortgage Loan Schedule, subject to review thereof by the Trustee, or by the applicable Custodian on behalf of the Trustee, under this Section 2.02. The Trustee, or the applicable Custodian on behalf of the Trustee, will execute and deliver to the Trustee, the Depositor and the Master Servicer on the Closing Date an Initial Certification in the form annexed hereto as Exhibit B-1 (or in the form annexed to the applicable Custodial Agreement as Exhibit B-1, as applicable.

(b) Within 45 days after the Closing Date, the Trustee or the applicable Custodian will, on behalf of the Trustee and for the benefit of Holders of the Certificates, review each Mortgage File to ascertain that all required documents set forth in Section 2.01 have been received and appear on their face to contain the requisite signatures by or on behalf of the respective parties thereto, and shall deliver to the Trustee, the Depositor and the Master Servicer an Interim Certification in the form annexed hereto as Exhibit B-2 (or in the form annexed to the applicable Custodial Agreement as Exhibit B-2, as applicable to the effect that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan prepaid in full or any Mortgage Loan specifically identified in such certification as not covered by such certification), (i) all of the applicable documents specified in Section 2.01(b) are in its possession and (ii) such documents have been reviewed by it and appear to relate to such Mortgage Loan. The Trustee, or the applicable Custodian on behalf of the Trustee, shall make sure that the documents are executed and endorsed, but shall be under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine that the same are valid, binding, legally effective, properly endorsed, genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded or are in recordable form or that they are other than what they purport to be on their face. Neither the Trustee nor any Custodian shall have any responsibility for verifying the genuineness or the legal effectiveness of or authority for any signatures of or on behalf of any party or endorser.

(c) If in the course of the review described in paragraph (b) above the Trustee or the applicable Custodian discovers any document or documents constituting a part of a Mortgage File that is missing, does not appear regular on its face (i.e., is mutilated, damaged, defaced, torn or otherwise physically altered) or appears to be unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule (each, a “Material Defect”), the Trustee, or the applicable Custodian on behalf of the Trustee, shall promptly identify the Mortgage Loan to which such Material Defect relates in the Interim Certification delivered to the Depositor, the Master Servicer and the Trustee. Within 90 days of its receipt of such notice, the Transferor, or if the Transferor does not do so, the Depositor shall be required to cure such Material Defect (and, in such event, the Depositor shall provide the Trustee with an Officer’s Certificate confirming that such cure has been effected). If the applicable Transferor or the Depositor, as applicable, does not so cure such Material Defect, it shall, if a loss has been incurred with respect to such Mortgage Loan that would, if such Mortgage Loan were not purchased from the Trust Fund, constitute a Realized Loss, and such loss is attributable to the failure of the applicable Transferor or the Depositor to cure such Material Defect, repurchase the related Mortgage Loan from the Trust Fund at the Purchase Price. A loss shall be deemed to be attributable to the failure of the applicable Transferor or the Depositor to cure a Material Defect if, as determined by the Depositor, upon mutual agreement with the Master Servicer acting in good faith, absent such Material Defect, such loss would not have been incurred. Within the two-year period following the Closing Date, the Depositor may, in lieu of repurchasing a Mortgage Loan pursuant to this Section 2.02, substitute for such Mortgage Loan a Qualifying Substitute Mortgage Loan subject to the provisions of Section 2.05. The failure of the Trustee or the applicable Custodian to give the notice contemplated herein within 45 days after the Closing Date shall not affect or relieve the Depositor of its obligation to repurchase any Mortgage Loan pursuant to this Section 2.02 or any other Section of this Agreement requiring the repurchase of Mortgage Loans from the Trust Fund.

(d) Within 180 days following the Closing Date, the Trustee, or the applicable Custodian, shall deliver to the Trustee, the Depositor and the Master Servicer a Final Certification substantially in the form annexed hereto as Exhibit B-3 (or in the form annexed to the applicable Custodial Agreement as Exhibit B-3, as applicable evidencing the completeness of the Mortgage Files in its possession or control, with any exceptions noted thereto.

(e) Nothing in this Agreement shall be construed to constitute an assumption by the Trust Fund, the Trustee or the Certificateholders of any unsatisfied duty, claim or other liability on any Mortgage Loan or to any Mortgagor.

(f) Each of the parties hereto acknowledges that each Custodian shall perform the applicable review of the Mortgage Loans covered by its Custodial Agreement and deliver the respective certifications thereof as provided in this Section 2.02.

Section 2.03. Representations and Warranties of the Depositor.

(a) The Depositor hereby represents and warrants to the Trustee, for the benefit of Certificateholders, and to the Master Servicer, as of the Closing Date or such other date as is specified, that:

(i) the Depositor is a corporation duly organized, validly existing and in good standing under the laws governing its creation and existence and has full corporate power and authority to own its property, to carry on its business as presently conducted, to enter into and perform its obligations under this Agreement, and to create the trust pursuant hereto;

(ii) the execution and delivery by the Depositor of this Agreement have been duly authorized by all necessary corporate action on the part of the Depositor; neither the execution and delivery of this Agreement, nor the consummation of the transactions herein contemplated, nor compliance with the provisions hereof, will conflict with or result in a breach of, or constitute a default under, any of the provisions of any law, governmental rule, regulation, judgment, decree or order binding on the Depositor or its properties or the certificate of incorporation or bylaws of the Depositor;

(iii) the execution, delivery and performance by the Depositor of this Agreement and the consummation of the transactions contemplated hereby do not require the consent or approval of, the giving of notice to, the registration with, or the taking of any other action in respect of, any state, federal or other governmental authority or agency, except such as has been obtained, given, effected or taken prior to the date hereof;

(iv) this Agreement has been duly executed and delivered by the Depositor and, assuming due authorization, execution and delivery by the Trustee and the Master Servicer, constitutes a valid and binding obligation of the Depositor enforceable against it in accordance with its terms except as such enforceability may be subject to (A) applicable bankruptcy and insolvency laws and other similar laws affecting the enforcement of the rights of creditors generally and (B) general principles of equity regardless of whether such enforcement is considered in a proceeding in equity or at law;

(v) there are no actions, suits or proceedings pending or, to the knowledge of the Depositor, threatened or likely to be asserted against or affecting the Depositor, before or by any court, administrative agency, arbitrator or governmental body (A) with respect to any of the transactions contemplated by this Agreement or (B) with respect to any other matter which in the judgment of the Depositor will be determined adversely to the Depositor and will if determined adversely to the Depositor materially and adversely affect it or its business, assets, operations or condition, financial or otherwise, or adversely affect its ability to perform its obligations under this Agreement; and

(vi) immediately prior to the transfer and assignment of the Mortgage Loans to the Trustee, the Depositor was the sole owner of record and holder of each Mortgage Loan, and the Depositor had good and marketable title thereto, and had full right to transfer and sell each Mortgage Loan to the Trustee free and clear, subject only to (1) liens of current real property taxes and assessments not yet due and payable and, if the related Mortgaged Property is a condominium unit, any lien for common charges permitted by statute, (2) covenants, conditions and restrictions, rights of way, easements and other matters of public record as of the date of recording of such Mortgage acceptable to mortgage lending institutions in the area in which the related Mortgaged Property is located and specifically referred to in the lender’s Title Insurance Policy or attorney’s opinion of title and abstract of title delivered to the originator of such Mortgage Loan, and (3) such other matters to which like properties are commonly subject which do not, individually or in the aggregate, materially interfere with the benefits of the security intended to be provided by the Mortgage, of any encumbrance, equity, participation interest, lien, pledge, charge, claim or security interest, and had full right and authority, subject to no interest or participation of, or agreement with, any other party, to sell and assign each Mortgage Loan pursuant to this Agreement.

(b) The representations and warranties of each Transferor with respect to the related Mortgage Loans in the applicable Transfer Agreement, which have been assigned to the Trustee hereunder, were made as of the date specified in the applicable Transfer Agreement (or underlying agreement, if such Transfer Agreement is in the form of an assignment of a prior agreement). To the extent that any fact, condition or event with respect to a Mortgage Loan constitutes a breach of both (i) a representation or warranty of the applicable Transferor under the applicable Transfer Agreement and (ii) a representation or warranty of Xxxxxx Holdings under the Mortgage Loan Sale Agreement, the only right or remedy of the Trustee or of any Certificateholder shall be the Trustee’s right to enforce the obligations of the applicable Transferor under any applicable representation or warranty made by it. The Trustee acknowledges that Xxxxxx Holdings shall have no obligation or liability with respect to any breach of a representation or warranty made by it with respect to the Mortgage Loans if the fact, condition or event constituting such breach also constitutes a breach of a representation or warranty made by the applicable Transferor in the applicable Transfer Agreement, without regard to whether such Transferor fulfills its contractual obligations in respect of such representation or warranty. The Trustee further acknowledges that the Depositor shall have no obligation or liability with respect to any breach of any representation or warranty with respect to the Mortgage Loans (except as set forth in Section 2.03(a)(vi)) under any circumstances.

Section 2.04. Discovery of Breach.

It is understood and agreed that the representations and warranties (i) of the Depositor set forth in Section 2.03 hereof, (ii) of Xxxxxx Holdings set forth in the Mortgage Loan Sale Agreement and assigned to the Trustee by the Depositor hereunder and (iii) of each Transferor, assigned by Xxxxxx Holdings to the Depositor pursuant to the Mortgage Loan Sale Agreement and assigned to the Trustee by the Depositor hereunder, shall each survive delivery of the Mortgage Files and the Assignment of Mortgage of each Mortgage Loan to the Trustee and shall continue throughout the term of this Agreement. Upon discovery by any of the Depositor, the Master Servicer or the Trustee of a breach of any of such representations and warranties that adversely and materially affects the value of the related Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties. Within 90 days of the discovery of a breach of any representation or warranty given to the Trustee by the Depositor, any Transferor or Xxxxxx Holdings and assigned to the Trustee hereunder, the Depositor, such Transferor or Xxxxxx Holdings shall either (a) cure such breach in all material respects, (b) repurchase such Mortgage Loan or any property acquired in respect thereof from the Trustee at the Purchase Price or (c) within the two year period following the Closing Date, substitute a Qualifying Substitute Mortgage Loan for the affected Mortgage Loan. In the event of the discovery of a breach of any representation and warranty of any Transferor assigned to the Trustee, the Trustee shall enforce its rights under the applicable Transfer Agreement and the Mortgage Loan Sale Agreement for the benefit of the Certificateholders. As provided in the Mortgage Loan Sale Agreement, if any Transferor substitutes for a Mortgage Loan for which there is a breach of any representations and warranties in the related Transfer Agreement which adversely and materially affects the value of such Mortgage Loan and such substitute mortgage loan is not a Qualifying Substitute Mortgage Loan, under the terms of the Mortgage Loan Sale Agreement, Xxxxxx Holdings will, in exchange for such Substitute Mortgage Loan, either (i) provide the applicable Purchase Price for the affected Mortgage Loan or (ii) within two years of the Closing Date, substitute such affected Mortgage Loan with a Qualifying Substitute Mortgage Loan.

Section 2.05. Repurchase, Purchase or Substitution of Mortgage Loans.

(a) With respect to any Mortgage Loan repurchased by the Depositor pursuant to this Agreement, by Xxxxxx Holdings pursuant to the Mortgage Loan Sale Agreement or by any Transferor pursuant to the applicable Transfer Agreement, the principal portion of the funds received by the Trustee in respect of such repurchase of a Mortgage Loan will be considered a Principal Prepayment and shall be deposited in the Collection Account. The Trustee, upon receipt of the full amount of the Purchase Price for a Deleted Mortgage Loan, or upon its receipt of notification from the applicable Custodian that it has received the Mortgage File for a Qualifying Substitute Mortgage Loan substituted for a Deleted Mortgage Loan (and any applicable Substitution Amount), shall release or cause to be released and reassigned to the Depositor, Xxxxxx Holdings or the applicable Transferor, as applicable, the related Mortgage File for the Deleted Mortgage Loan and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty, as shall be necessary to vest in such party or its designee or assignee title to any Deleted Mortgage Loan released pursuant hereto, free and clear of all security interests, liens and other encumbrances created by this Agreement, which instruments shall be prepared by the applicable Servicer or the Trustee (or its custodian), and the Trustee shall have no further responsibility with respect to the Mortgage File relating to such Deleted Mortgage Loan. The Seller indemnifies and holds the Trust Fund, the Trustee, the Depositor and each Certificateholder harmless against any and all taxes, claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, fees and expenses that the Trust Fund, the Trustee, the Depositor and any Certificateholder may sustain in connection with any actions of the Seller relating to a repurchase of a Mortgage Loan other than in compliance with the terms of this Section 2.05 and the Mortgage Loan Sale Agreement, to the extent that any such action causes (i) any federal or state tax to be imposed on the Trust Fund, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(2) of the Code, or (ii) any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding.

(b) With respect to each Qualifying Substitute Mortgage Loan to be delivered to the Trustee (or its custodian) pursuant to the terms of this Article II in exchange for a Deleted Mortgage Loan: (i) the Depositor, the applicable Transferor or Xxxxxx Holdings must deliver to the Trustee (or its custodian) the Mortgage File for the Qualifying Substitute Mortgage Loan containing the documents set forth in Section 2.01(b) along with a written certification certifying as to the delivery of such Mortgage File and containing the granting language set forth in Section 2.01(a); and (ii) the Depositor will be deemed to have made, with respect to such Qualifying Substitute Mortgage Loan, each of the representations and warranties made by it with respect to the related Deleted Mortgage Loan. As soon as practicable after the delivery of any Qualifying Substitute Mortgage Loan hereunder, the Trustee, at the expense of the Depositor and at the direction and with the cooperation of the applicable Servicer, shall, with respect to a Qualifying Substitute Mortgage Loan that is a Non-MERS Mortgage Loan, cause the Assignment of Mortgage to be recorded by such Servicer if required pursuant to Section 2.01(c)(i), or the Servicer shall, with respect to a Qualifying Substitute Mortgage Loan that is a MERS Mortgage Loan, cause to be taken such actions as are necessary to cause the Trustee to be clearly identified as the owner of each such Mortgage Loan on the records of MERS if required pursuant to Section 2.01(c)(ii).

(c) Notwithstanding any other provision of this Agreement, the right to substitute Mortgage Loans pursuant to this Article II shall be subject to the additional limitations that no substitution of a Qualifying Substitute Mortgage Loan for a Deleted Mortgage Loan shall be made unless the Trustee has received an Opinion of Counsel (at the expense of the party seeking to make the substitution) that, under current law, such substitution will not (A) affect adversely the status of any REMIC established hereunder as a REMIC, or of the related “regular interests” as “regular interests” in any such REMIC, or (B) cause any such REMIC to engage in a prohibited transaction or prohibited contribution pursuant to the REMIC Provisions.

Section 2.06. Grant Clause.

(a) It is intended that the conveyance of the Depositor’s right, title and interest in and to property constituting the Trust Fund pursuant to this Agreement shall constitute, and shall be construed as, a sale of such property and not a grant of a security interest to secure a loan. However, if such conveyance is deemed to be in respect of a loan, it is intended that: (1) the rights and obligations of the parties shall be established pursuant to the terms of this Agreement; (2) the Depositor hereby grants to the Trustee for the benefit of the Holders of the Certificates a first priority security interest to secure repayment of an obligation in an amount equal to the aggregate Class Principal Amount of the Certificates in all of the Depositor’s right, title and interest in, to and under, whether now owned or hereafter acquired, the Trust Fund and all proceeds of any and all property constituting the Trust Fund to secure payment of the Certificates; and (3) this Agreement shall constitute a security agreement under applicable law. If such conveyance is deemed to be in respect of a loan and the Trust created by this Agreement terminates prior to the satisfaction of the claims of any Person holding any Certificate, the security interest created hereby shall continue in full force and effect and the Trustee shall be deemed to be the collateral agent for the benefit of such Person, and all proceeds shall be distributed as herein provided.

(b) The Depositor shall, to the extent consistent with this Agreement, take such reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the other property described above, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement. The Depositor will, at its own expense, make all initial filings on or about the Closing Date and shall forward a copy of such filing or filings to the Trustee. Without limiting the generality of the foregoing, the Depositor shall prepare and forward for filing, or shall cause to be forwarded for filing, at the expense of the Depositor, all filings necessary to maintain the effectiveness of any original filings necessary under the relevant UCC to perfect the Trustee’s security interest in or lien on the Mortgage Loans, including without limitation (x) continuation statements, and (y) such other statements as may be occasioned by (1) any change of name of the Seller, the Depositor or the Trustee, (2) any change of location of the jurisdiction of organization of the Seller or the Depositor, (3) any transfer of any interest of the Seller or the Depositor in any Mortgage Loan or (4) any change under the relevant UCC or other applicable laws. Neither the Seller nor the Depositor shall organize under the law of any jurisdiction other than the State under which each is organized as of the Closing Date (whether changing its jurisdiction of organization or organizing under an additional jurisdiction) without giving 30 days prior written notice of such action to its transferee, including the Trustee. Before effecting such change, the Seller or the Depositor proposing to change its jurisdiction of organization shall prepare and file in the appropriate filing office any financing statements or other statements necessary to continue the perfection of the interests of its transferees, including the Trustee, in the Mortgage Loans. In connection with the transactions contemplated by this Agreement, each of the Seller and the Depositor authorizes its transferee to file in any filing office any initial financing statements, any amendments to financing statements, any continuation statements, or any other statements or filings described in this paragraph (b).

In addition, each Holder of a Regulation S Global Security shall be deemed to have represented and warranted to the Trustee, the Certificate Registrar and any of their respective successors that: (i) such Person (A) if the offer or sale was made to it prior to the expiration of the 40-day distribution compliance period within the meaning of Regulation S, is not a U.S. person within the meaning of Regulation S and (B) was, at the time the buy order was originated, outside the United States and (ii) such Person understands that such Certificates have not been registered under the Securities Act, and that (x) until the expiration of the 40-day distribution compliance period (within the meaning of Regulation S), no offer, sale, pledge or other transfer of such Certificates or any interest therein shall be made in the United States or to or for the account or benefit of a U.S. person (each as defined in Regulation S), (y) if in the future it decides to offer, resell, pledge or otherwise transfer such Certificates, such Certificates may be offered, resold, pledged or otherwise transferred only (A) to a person which the seller reasonably believes is a “qualified institutional buyer” (a “QIB”) as defined in Rule 144A under the Act, that is purchasing such Certificates for its own account or for the account of a qualified institutional buyer to which notice is given that the transfer is being made in reliance on Rule 144A or (B) in an offshore transaction (as defined in Regulation S) in compliance with the provisions of Regulation S, in each case in compliance with the requirements of this Agreement; and it will notify such transferee of the transfer restrictions specified in this Section.

The following restrictions shall apply with respect to the transfer and registration of transfer of a Restricted Certificate to a transferee that takes delivery in the form of a Definitive Certificate:

(i) The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is (x) to the Depositor or the Placement Agent or to an affiliate (as defined in Rule 405 under the Act) of the Depositor or the Placement Agent or (y) being made to a QIB by a transferor that has provided the Trustee with a certificate in the form of Exhibit F hereto; and

(ii) The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is being made to an “accredited investor” under Rule 501(a)(1), (2), (3) or (7) under the Act by a transferor who furnishes to the Trustee a letter of the transferee substantially in the form of Exhibit G hereto.

(d) No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate shall be made to any Person or shall be effective unless the Trustee has received (A) a certificate substantially in the form of Exhibit H hereto (or Exhibit D-1, in the case of a Residual Certificate) from such transferee or (B) an Opinion of Counsel reasonably satisfactory to the Trustee to the effect that the purchase and holding of such a Certificate will not constitute or result in prohibited transactions under Title I of ERISA or Section 4975 of the Code and will not subject the Trustee, the Master Servicer or the Depositor to any obligation in addition to those undertaken in the Agreement; provided, however, that the Trustee will not require such certificate or opinion in the event that, as a result of a change of law or otherwise, the Trustee receives an Opinion of Counsel to the effect that the purchase and holding of an ERISA-Restricted Certificate by a Plan or a Person that is purchasing or holding such a Certificate with the assets of a Plan will not constitute or result in a prohibited transaction under Title I of ERISA or Section 4975 of the Code. Each Transferee of an ERISA-Restricted Certificate that is a Book-Entry Certificate shall be deemed to have made the representations set forth in Exhibit H. The preparation and delivery of the certificate and opinions referred to above shall not be an expense of the Trust Fund, the Trustee, the Master Servicer or the Depositor.

Notwithstanding the foregoing, no opinion or certificate shall be required for the initial issuance of the ERISA-Restricted Certificates. The Trustee shall have no obligation to monitor transfers of Book-Entry Certificates that are ERISA-Restricted Certificates and shall have no liability for transfers of such Certificates in violation of the transfer restrictions. The Trustee shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 3.03(d) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trustee in accordance with the foregoing requirements. The Trustee shall be entitled, but not obligated, to recover from any Holder of any ERISA-Restricted Certificate that was in fact a Plan or a Person acting on behalf of a Plan any payments made on such ERISA-Restricted Certificate at and after either such time. Any such payments so recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Holder of such Certificate that is not such a Plan or Person acting on behalf of a Plan.

(e) As a condition of the registration of transfer or exchange of any Certificate, the Certificate Registrar may require the certified taxpayer identification number of the owner of the Certificate and the payment of a sum sufficient to cover any tax or other governmental charge imposed in connection therewith; provided, however, that the Certificate Registrar shall have no obligation to require such payment or to determine whether or not any such tax or charge may be applicable. No service charge shall be made to the Certificateholder for any registration, transfer or exchange of Certificate.

(f) Notwithstanding anything to the contrary contained herein, no Residual Certificate may be owned, pledged or transferred, directly or indirectly, by or to (i) a Disqualified Organization or (ii) an individual, corporation or partnership or other person unless such person is (A) not a Non-U.S. Person or (B) is a Non-U.S. Person that holds a Residual Certificate in connection with the conduct of a trade or business within the United States and has furnished the transferor and the Trustee with an effective Internal Revenue Service Form W-8ECI or successor form at the time and in the manner required by the Code (any such person who is not covered by clause (A) or (B) above is referred to herein as a “Non-permitted Foreign Holder”).

Prior to and as a condition of the registration of any transfer, sale or other disposition of a Residual Certificate, the proposed transferee shall deliver to the Trustee an affidavit in substantially the form attached hereto as Exhibit D-1 representing and warranting, among other things, that such transferee is neither a Disqualified Organization, an agent or nominee acting on behalf of a Disqualified Organization, nor a Non-permitted Foreign Holder (any such transferee, a “Permitted Transferee”) and the proposed transferor shall deliver to the Trustee an affidavit in substantially the form attached hereto as Exhibit D-2. In addition, the Trustee may (but shall have no obligation to) require, prior to and as a condition of any such transfer, the delivery by the proposed transferee of an Opinion of Counsel, addressed to the Depositor and the Trustee satisfactory in form and substance to the Depositor, that such proposed transferee or, if the proposed transferee is an agent or nominee, the proposed beneficial owner, is not a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder. Notwithstanding the registration in the Certificate Register of any transfer, sale, or other disposition of a Residual Certificate to a Disqualified Organization, an agent or nominee thereof, or Non-permitted Foreign Holder, such registration shall be deemed to be of no legal force or effect whatsoever and such Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder shall not be deemed to be a Certificateholder for any purpose hereunder, including, but not limited to, the receipt of distributions on such Residual Certificate. The Trustee shall not be under any liability to any person for any registration or transfer of a Residual Certificate to a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder or for the maturity of any payments due on such Residual Certificate to the Holder thereof or for taking any other action with respect to such Holder under the provisions of the Agreement, so long as the transfer was effected in accordance with this Section 3.03(f), unless the Trustee shall have actual knowledge at the time of such transfer or the time of such payment or other action that the transferee is a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder. The Trustee shall be entitled to recover from any Holder of a Residual Certificate that was a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder at the time it became a Holder or any subsequent time it became a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder, all payments made on such Residual Certificate at and after either such times (and all costs and expenses, including but not limited to attorneys’ fees, incurred in connection therewith). Any payment (not including any such costs and expenses) so recovered by the Trustee shall be paid and delivered to the last preceding Holder of such Residual Certificate.

If any purported transferee shall become a registered Holder of a Residual Certificate in violation of the provisions of this Section 3.03(f), then upon receipt of written notice to the Trustee that the registration of transfer of such Residual Certificate was not in fact permitted by this Section 3.03(f), the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of such registration of transfer of such Residual Certificate. The Trustee 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 3.03(f), for making any payment due on such Certificate to the registered Holder thereof or for taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered upon receipt of the affidavit described in the preceding paragraph of this Section 3.03(f).

(g) Each Holder of a Residual Certificate, by such Holder’s acceptance thereof, shall be deemed for all purposes to have consented to the provisions of this section.

(h) Notwithstanding any provision to the contrary herein, so long as a Global Security representing any of the Class B4, Class B5 or Class B6 Certificates remains outstanding and is held by or on behalf of DTC, transfers of a Global Security representing any such Certificates, in whole or in part, shall only be made in accordance with Section 3.01 and this Section 3.03(h).

(A) Subject to clauses (B) and (C) of this Section 3.03(h), transfers of a Global Security representing any of the Class B4, Class B5 or Class B6 Certificates shall be limited to transfers of such Global Security, in whole or in part, to nominees of DTC or to a successor of DTC or such successor’s nominee.

(B) Restricted Global Security to Regulation S Global Security. If a holder of a beneficial interest in a Restricted Global Security deposited with or on behalf of DTC wishes at any time to exchange its interest in such Restricted Global Security for an interest in a Regulation S Global Security, or to transfer its interest in such Restricted Global Security to a Person who wishes to take delivery thereof in the form of an interest in a Regulation S Global Security, such holder, provided such holder is not a U.S. person, may, subject to the rules and procedures of DTC, exchange or cause the exchange of such interest for an equivalent beneficial interest in the Regulation S Global Security. Upon receipt by the Trustee, as Certificate Registrar, of (I) instructions from DTC directing the Trustee, as Certificate Registrar, to cause to be credited a beneficial interest in a Regulation S Global Security in an amount equal to the beneficial interest in such Restricted Global Security to be exchanged but not less than the minimum denomination applicable to such holder’s Certificates held through a Regulation S Global Security, (II) a written order given in accordance with DTC’s procedures containing information regarding the participant account of DTC and, in the case of a transfer pursuant to and in accordance with Regulation S, the Euroclear or Clearstream account to be credited with such increase and (III) a certificate in the form of Exhibit N-1 hereto given by the holder of such beneficial interest stating that the exchange or transfer of such interest has been made in compliance with the transfer restrictions applicable to the Regulation S Global Securities, including that the holder is not a U.S. person, and pursuant to and in accordance with Regulation S, the Trustee, as Certificate Registrar, shall reduce the principal amount of the Restricted Global Security and increase the principal amount of the Regulation S Global Security by the aggregate principal amount of the beneficial interest in the Restricted Global Security to be exchanged, and shall instruct Euroclear or Clearstream, as applicable, concurrently with such reduction, to credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Regulation S Global Security equal to the reduction in the principal amount of the Restricted Global Security.

(C) Regulation S Global Security to Restricted Global Security. If a holder of a beneficial interest in a Regulation S Global Security deposited with or on behalf of DTC wishes at any time to transfer its interest in such Regulation S Global Security to a Person who wishes to take delivery thereof in the form of an interest in a Restricted Global Security, such holder may, subject to the rules and procedures DTC, exchange or cause the exchange of such interest for an equivalent beneficial interest in a Restricted Global Security. Upon receipt by the Trustee, as Certificate Registrar, of (I) instructions from DTC directing the Trustee, as Certificate Registrar, to cause to be credited a beneficial interest in a Restricted Global Security in an amount equal to the beneficial interest in such Regulation S Global Security to be exchanged but not less than the minimum denomination applicable to such holder’s Certificates held through a Restricted Global Security, to be exchanged, such instructions to contain information regarding the participant account with DTC to be credited with such increase, and (II) a certificate in the form of Exhibit N-2 hereto given by the holder of such beneficial interest and stating, among other things, that the Person transferring such interest in such Regulation S Global Security reasonably believes that the Person acquiring such interest in a Restricted Global Security is a QIB, is obtaining such beneficial interest in a transaction meeting the requirements of Rule 144A and in accordance with any applicable securities laws of any State of the United States or any other jurisdiction, then the Trustee, as Certificate Registrar, will reduce the principal amount of the Regulation S Global Security and increase the principal amount of the Restricted Global Security by the aggregate principal amount of the beneficial interest in the Regulation S Global Security to be transferred and the Trustee, as Certificate Registrar, shall instruct DTC, concurrently with such reduction, to credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Restricted Global Security equal to the reduction in the principal amount of the Regulation S Global Security.

(D) Other Exchanges. In the event that a Global Security is exchanged for Certificates in definitive registered form without interest coupons, pursuant to Section 3.09(c) hereof, such Certificates may be exchanged for one another only in accordance with such procedures as are substantially consistent with the provisions above (including certification requirements intended to insure that such transfers comply with Rule 144A, comply with Rule 501(a)(1), (2), (3) or (7) or are to non U.S. persons in compliance with Regulation S under the Act, as the case may be), and as may be from time to time adopted by the Trustee.

(E) Restrictions on U.S. Transfers. Transfers of interests in a Regulation S Global Security to U.S. persons (as defined in Regulation S) shall be limited to transfers made pursuant to the provisions of Section 3.03(h)(C).

Section 3.04. Cancellation of Certificates.

Any Certificate surrendered for registration of transfer or exchange shall be cancelled and retained in accordance with normal retention policies with respect to cancelled certificates maintained by the Trustee or the Certificate Registrar.

Section 3.05. Replacement of Certificates.

If (i) any Certificate is mutilated and is surrendered to the Trustee or any Authenticating Agent or (ii) the Trustee or any Authenticating Agent receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and there is delivered to the Trustee or the Authenticating Agent such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Depositor and any Authenticating Agent that such destroyed, lost or stolen Certificate has been acquired by a bona fide purchaser, the Trustee shall execute and the Trustee or any Authenticating Agent shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and Certificate Principal Amount (or Notional Amount). Upon the issuance of any new Certificate under this Section 3.05, the Trustee and Authenticating Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee or the Authenticating Agent) connected therewith. Any replacement Certificate issued pursuant to this Section 3.05 shall constitute complete and indefeasible evidence of ownership in the applicable Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 3.06. Persons Deemed Owners.

Subject to the provisions of Section 3.09 with respect to Book-Entry Certificates, the Depositor, the Master Servicer, the Trustee, the Certificate Registrar and any agent of any of them may treat the Person in whose name any Certificate is registered upon the books of the Certificate Registrar as the owner of such Certificate for the purpose of receiving distributions pursuant to Sections 5.01 and 5.02 and for all other purposes whatsoever, and neither the Depositor, the Master Servicer, the Trustee, the Certificate Registrar nor any agent of any of them shall be affected by notice to the contrary.

Section 3.07. Temporary Certificates.

(a) Pending the preparation of definitive Certificates, upon the order of the Depositor, the Trustee shall execute and shall authenticate and deliver temporary Certificates that are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Certificates in lieu of which they are issued and with such variations as the authorized officers executing such Certificates may determine, as evidenced by their execution of such Certificates.

(b) If temporary Certificates are issued, the Depositor will cause definitive Certificates to be prepared without unreasonable delay. After the preparation of definitive Certificates, the temporary Certificates shall be exchangeable for definitive Certificates upon surrender of the temporary Certificates at the office or agency of the Trustee without charge to the Holder. Upon surrender for cancellation of any one or more temporary Certificates, the Trustee shall execute and authenticate and deliver in exchange therefor a like aggregate Certificate Principal Amount of definitive Certificates of the same Class in the authorized denominations. Until so exchanged, the temporary Certificates shall in all respects be entitled to the same benefits under this Agreement as definitive Certificates of the same Class.

Section 3.08. Appointment of Paying Agent.

The Trustee may appoint a Paying Agent (which may be the Trustee) for the purpose of making distributions to Certificateholders hereunder. The Trustee shall cause such Paying Agent (if other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee that such Paying Agent will hold all sums held by it for the payment to Certificateholders in an Eligible Account in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to the Certificateholders. All funds remitted by the Trustee to any such Paying Agent for the purpose of making distributions shall be paid to Certificateholders on each Distribution Date and any amounts not so paid shall be returned on such Distribution Date to the Trustee. If the Paying Agent is not the Trustee, the Trustee shall cause to be remitted to the Paying Agent on or before the Business Day prior to each Distribution Date, by wire transfer in immediately available funds, the funds to be distributed on such Distribution Date. Any Paying Agent shall be either a bank or trust company or otherwise authorized under law to exercise corporate trust powers.

Section 3.09. Book-Entry Certificates.

(i) Each Class of Book-Entry Certificates, upon original issuance, shall be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates, to be delivered to The Depository Trust Company, or its custodian, the initial Clearing Agency, by, or on behalf of, the Depositor. The Book-Entry Certificates shall initially be registered on the Certificate Register in the name of the nominee of the Clearing Agency, and no Certificate Owner will receive a definitive certificate representing such Certificate Owner’s interest in the Book-Entry Certificates, except as provided in Section 3.09(c). Unless Definitive Certificates have been issued to Certificate Owners of Book-Entry Certificates pursuant to Section 3.09(c):

(ii) the provisions of this Section 3.09 shall be in full force and effect;

(iii) the Depositor, the Master Servicer, the Paying Agent, the Certificate Registrar and the Trustee may deal with the Clearing Agency for all purposes (including the making of distributions on the Book-Entry Certificates) as the authorized representatives of the Certificate Owners and the Clearing Agency shall be responsible for crediting the amount of such distributions to the accounts of such Persons entitled thereto, in accordance with the Clearing Agency’s normal procedures;

(iv) to the extent that the provisions of this Section 3.09 conflict with any other provisions of this Agreement, the provisions of this Section 3.09 shall control; and

(v) the rights of Certificate Owners shall be exercised only through the Clearing Agency and the Clearing Agency Participants and shall be limited to those established by law and agreements between such Certificate Owners and the Clearing Agency and/or the Clearing Agency Participants. Unless and until Definitive Certificates are issued pursuant to Section 3.09(c), the initial Clearing Agency will make book-entry transfers among the Clearing Agency Participants and receive and transmit distributions of principal of and interest on the Book-Entry Certificates to such Clearing Agency Participants.

(b) Whenever notice or other communication to the Certificateholders is required under this Agreement, unless and until Definitive Certificates shall have been issued to Certificate Owners pursuant to Section 3.09(c), the Trustee shall give all such notices and communications specified herein to be given to Holders of the Book-Entry Certificates to the Clearing Agency.

(c) If (i) (A) the Depositor advises the Trustee in writing that the Clearing Agency is no longer willing or able to discharge properly its responsibilities with respect to the Book-Entry Certificates, and (B) the Trustee or the Depositor is unable to locate a qualified successor or (ii) after the occurrence of an Event of Default, Certificate Owners representing beneficial interests aggregating not less than 50% of the Class Principal Amount of a Class of Book-Entry Certificates identified as such to the Trustee by an Officer’s Certificate from the Clearing Agency advise the Trustee and the Clearing Agency through the Clearing Agency Participants in writing that the continuation of a book-entry system through the Clearing Agency is no longer in the best interests of the Certificate Owners of a Class of Book-Entry Certificates, the Trustee shall notify or cause the Certificate Registrar to notify the Clearing Agency to effect notification to all Certificate Owners, through the Clearing Agency, 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 Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration, the Trustee shall issue the Definitive Certificates. Neither the Transferor nor the Trustee shall be liable for any delay in 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 Clearing Agency 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.

ARTICLE IV

ADMINISTRATION OF THE TRUST FUND

Section 4.01. Collection Account.

(a) On the Closing Date, the Master Servicer shall open and shall thereafter maintain a segregated account held in trust (the “Collection Account”), entitled “Aurora Loan Services Inc., as Master Servicer, in trust for the benefit of the Holders of Structured Asset Securities Corporation Mortgage Pass-Through Certificates, Series 2004-15.” The Collection Account shall relate solely to the Certificates issued by the Trust Fund hereunder, and funds in such Collection Account shall not be commingled with any other monies.

(b) The Collection Account shall be an Eligible Account. If an existing Collection Account ceases to be an Eligible Account, the Master Servicer shall establish a new Collection Account that is an Eligible Account within 30 days and transfer all funds on deposit in such existing Collection Account into such new Collection Account.

(c) The Master Servicer shall give to the Trustee prior written notice of the name and address of the depository institution at which the Collection Account is maintained and the account number of such Collection Account. On each Deposit Date, the entire amount on deposit in the Collection Account (subject to permitted withdrawals set forth in Section 4.02), excluding any amounts that are not included in the Available Distribution Amount for such Distribution Date (other than amounts due or reimbursable to the Trustee pursuant to this Agreement), shall be remitted to the Trustee for deposit into the Certificate Account by wire transfer in immediately available funds. The Master Servicer, at its option and with prior notice to the Trustee, may choose to make daily remittances from the Collection Account to the Trustee for deposit into the Certificate Account.

(d) The Master Servicer shall deposit or cause to be deposited into the Collection Account, no later than the Business Day following the Closing Date, any amounts representing Scheduled Payments on the Mortgage Loans due after the Cut-off Date and received by the Master Servicer on or before the Closing Date. Thereafter, the Master Servicer shall deposit or cause to be deposited in the Collection Account on the applicable Remittance Date the following amounts received or payments made by it (other than in respect of principal of and interest on the Mortgage Loans due on or before the Cut-Off Date):

(i) all payments on account of principal, including Principal Prepayments, late collections and any Prepayment Penalty Amounts with respect to those Mortgage Loans for which the Seller owns the servicing rights, as indicated in the Mortgage Loan Schedule, on the Mortgage Loans;

(ii) all payments on account of interest on the Mortgage Loans (other than payments due prior to the Cut-off Date), net of the applicable Servicing Fee and Master Servicing Fee with respect to each such Mortgage Loan, but only to the extent of the amount permitted to be withdrawn or withheld from the Collection Account in accordance with Sections 5.04 and 9.21;

(iii) any unscheduled payment or other recovery with respect to a Mortgage Loan not otherwise specified in this paragraph (d), including any Subsequent Recovery, all Net Liquidation Proceeds with respect to the Mortgage Loans and REO Property, and all amounts received in connection with the operation of any REO Property, net of any unpaid Servicing Fees and Master Servicing Fees with respect to such Mortgage Loans, but only to the extent of the amount permitted to be withdrawn or withheld from the Collection Account in accordance with Sections 5.04 and 9.21; provided that if the applicable Servicer is also the Retained Interest Holder with respect to any Mortgage Loan, payments on account of interest on the Mortgage Loans as to which such Servicer is the Retained Interest Holder may also be made net of the related Retained Interest with respect to each such Mortgage Loan.

(iv) all Insurance Proceeds;

(v) all Advances made by the Master Servicer or any Servicer pursuant to Section 5.04 or the applicable Servicing Agreement; and

(vi) all proceeds of any Mortgage Loan purchased by any Person and any Substitution Amounts related to any Qualifying Substitute Mortgage Loan.

(e) Funds in the Collection Account may be invested in Eligible Investments (selected by and at the written direction of the Master Servicer) which shall mature not later than the earlier of (a) the Deposit Date or (b) the day on which the funds in such Collection Account are required to be remitted to the Trustee for deposit into the Certificate Account, and any such Eligible Investment shall not be sold or disposed of prior to its maturity. All such Eligible Investments shall be made in the name of the Master Servicer in trust for the benefit of the Trustee and Holders of the Structured Asset Securities Corporation Mortgage Pass-Through Certificates, Series 2004-15. All income and gain realized from any such investment shall be for the benefit of the Master Servicer as additional compensation and shall be subject to its withdrawal on order from time to time, and shall not be part of the Trust Fund. The amount of any losses incurred in respect of any such investments shall be deposited in the Collection Account by the Master Servicer out of its own funds, without any right of reimbursement therefor, immediately as realized. The foregoing requirements for deposit in the Collection Account are exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments of interest on funds in the Collection Account and payments in the nature of late payment charges or assumption fees and Prepayment Penalty Amounts with respect to those Mortgage Loans for which the Seller does not own the servicing rights (as indicated in the Mortgage Loan Schedule), need not be deposited by the Master Servicer in the Collection Account and may be retained by the Master Servicer or the applicable Servicer as additional servicing compensation. If the Master Servicer deposits in the Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from the Collection Account.

Section 4.02. Application of Funds in the Collection Account.

The Master Servicer may, from time to time, make, or cause to be made, withdrawals from the Collection Account for the following purposes:

(i) to reimburse itself or any Servicer for Advances made by it or by such Servicer pursuant to Section 5.04 or the applicable Servicing Agreement; provided, however, that the Master Servicer’s right to reimburse itself pursuant to this subclause is limited to amounts received on or in respect of particular Mortgage Loans (including, for this purpose, Liquidation Proceeds and amounts representing Insurance Proceeds with respect to the property subject to the related Mortgage) which represent late recoveries (net of the applicable Servicing Fee and the Master Servicing Fee) of payments of principal or interest respecting which any such Advance was made; provided, further, that following the final liquidation of a Mortgage Loan, the Master Servicer may reimburse itself for previously unreimbursed Advances in excess of Liquidation Proceeds or Insurance Proceeds with respect to such Mortgage Loans from any funds in the Collection Account, it being understood, in the case of any such reimbursement, that the Master Servicer’s or Servicer’s right thereto shall be prior to the rights of the Certificateholders;

(ii) to reimburse itself or any Servicer for any Servicing Advances made by it or by such Servicer that it or such Servicer determines in good faith will not be recoverable from amounts representing late recoveries of payments of principal or interest respecting the particular Mortgage Loan as to which such Servicing Advance was made or from Liquidation Proceeds or Insurance Proceeds with respect to such Mortgage Loan, it being understood, in the case of any such reimbursement, that such Master Servicer’s or Servicer’s right thereto shall be prior to the rights of the Certificateholders;

(iii) to reimburse itself or any Servicer from Liquidation Proceeds for Liquidation Expenses and for amounts expended by it pursuant to Sections 9.20 and 9.22(a) or the applicable Servicing Agreement in good faith in connection with the restoration of damaged property and, to the extent that Liquidation Proceeds after such reimbursement exceed the unpaid principal balance of the related Mortgage Loan, together with accrued and unpaid interest thereon at the applicable Mortgage Rate less the applicable Servicing Fee and the Master Servicing Fee for such Mortgage Loan to the Due Date next succeeding the date of its receipt of such Liquidation Proceeds, to pay to itself out of such excess the amount of any unpaid assumption fees, late payment charges or other Mortgagor charges on the related Mortgage Loan and to retain any excess remaining thereafter as additional servicing compensation, it being understood, in the case of any such reimbursement or payment, that such Master Servicer’s or Servicer’s right thereto shall be prior to the rights of the Certificateholders;

(iv) to reimburse itself or any Servicer for expenses incurred by and recoverable by or reimbursable to it or such Servicer pursuant to Section 9.04, 9.05, 9.06, 9.16 or 9.22(a) or pursuant to the applicable Servicing Agreement, and to reimburse itself for any expenses reimbursable to it pursuant to Section 10.01(c);

(v) to pay to the applicable Person, with respect to each Mortgage Loan or REO Property acquired in respect thereof that has been repurchased by such Person pursuant to this Agreement, all amounts received thereon and not distributed on the date on which the related repurchase was effected;

(vi) subject to Section 5.05, to pay to itself income earned on the investment of funds deposited in the Collection Account;

(vii) to make payments to the Trustee for deposit into the Certificate Account in the amounts and in the manner provided for in Section 4.01(c);

(viii) to make distributions of any Retained Interest to the Retained Interest Holder on each Distribution Date (other than any Retained Interest not deposited into the Collection Account in accordance with Section 4.01(d)(iii));

(ix) to make payment to itself, the Trustee and others pursuant to any provision of this Agreement;

(x) to withdraw funds deposited in error in the Collection Account;

(xi) to clear and terminate the Collection Account pursuant to Section 7.02;

(xii) to reimburse a successor Master Servicer (solely in its capacity as successor Master Servicer), for any fee or advance occasioned by a termination of the Master Servicer, and the assumption of such duties by the Trustee or a successor Master Servicer appointed by the Trustee pursuant to Section 6.14, in each case to the extent not reimbursed by the terminated Master Servicer, it being understood, in the case of any such reimbursement or payment, that the right of the Master Servicer or the Trustee thereto shall be prior to the rights of the Certificateholders; and

(xiii) to reimburse any Servicer for such amounts as are due thereto under the applicable Servicing Agreement and have not been retained by or paid to such Servicer to the extent provided in such Servicing Agreement.

If provided in the related Servicing Agreement, each Servicer shall be entitled to retain as additional servicing compensation any Prepayment Interest Excess (to the extent not offset by Prepayment Interest Shortfalls).

In the event that the Master Servicer fails on any Deposit Date to remit to the Trustee any amounts required to be so remitted to the Trustee pursuant to subclause (vii) by 12 noon (New York time) on such date, the Master Servicer shall pay the Trustee, for the account of the Trustee, interest calculated at the “prime rate” (as published in the “Money Rates” section of The Wall Street Journal) on such amounts not timely remitted for the period from and including that Deposit Date to but not including the related Distribution Date.

In connection with withdrawals pursuant to subclauses (i), (iii), (iv) and (vi) above, the Master Servicer’s or Servicer’s entitlement thereto is limited to collections or other recoveries on the related Mortgage Loan, except as provided herein. The Master Servicer shall therefore keep and maintain a separate accounting for each Mortgage Loan it master services for the purpose of justifying any withdrawal from the Collection Account it maintains pursuant to subclauses (i), (iii), (iv) and (vi) above.

Section 4.03. Reports to Certificateholders.

(a) On each Distribution Date, the Trustee shall prepare (based solely on information provided by the Master Servicer) and shall make available to each Certificateholder and each Rating Agency a written report setting forth the following information (on the basis of Mortgage Loan level information obtained from the Servicers and the Master Servicer):

(i) the aggregate amount of the distribution to be made on such Distribution Date to the Holders of each Class of Certificates, other than any Class of Notional Certificates, and in respect of each Component, to the extent applicable, allocable to principal on the Mortgage Loans, including any Subsequent Recovery, Liquidation Proceeds and Insurance Proceeds, stating separately the amount attributable to scheduled principal payments and unscheduled payments in the nature of principal in each Mortgage Pool;

The Trustee shall have the right to change the way such statements are distributed in order to make such distribution more convenient and/or more accessible to the above-parties and the Trustee shall provide timely and adequate notification to all above-parties regarding any such changes.

The foregoing information and reports shall be prepared and determined by the Trustee based solely on Mortgage Loan data provided to the Trustee by the Master Servicer (in a format agreed to by the Trustee and the Master Servicer) no later than 12:00 p.m.(noon) Eastern Time four Business Days prior to the Distribution Date. In preparing or furnishing Mortgage Loan data to the Trustee, the Master Servicer shall be entitled to rely conclusively on the accuracy of the information or data regarding the Mortgage Loans and the related REO Property that has been provided to the Master Servicer by each Servicer, and the Master Servicer shall not be obligated to verify, recompute, reconcile or recalculate any such information or data.

Such information shall include the amount of original issue discount accrued on each Class of Certificates and information regarding the expenses of the Trust Fund. The Trustee shall be deemed to have satisfied this requirement if it forwards such information in any other format permitted by the Code.

Section 4.04. Certificate Account.

(a) The Trustee shall establish and maintain in its name, as trustee, a trust account (the “Certificate Account”), to be held in trust for the benefit of the Certificateholders until disbursed pursuant to the terms of this Agreement. The Certificate Account shall be an Eligible Account. If the existing Certificate Account ceases to be an Eligible Account, the Trustee shall establish a new Certificate Account that is an Eligible Account within 20 Business Days and transfer all funds on deposit in such existing Certificate Account into such new Certificate Account. The Certificate Account shall relate solely to the Certificates issued hereunder and funds in the Certificate Account shall be held separate and apart from and shall not be commingled with any other monies including, without limitation, other monies of the Trustee held under this Agreement.

(b) The Trustee shall cause to be deposited into the Certificate Account on the day on which, or, if such day is not a Business Day, the Business Day immediately following the day on which, any monies are remitted by the Master Servicer to the Trustee, all such amounts. The Trustee shall make withdrawals from the Certificate Account only for the following purposes:

(i) to withdraw amounts deposited in the Certificate Account in error;

(ii) to pay itself any investment income earned with respect to funds in the Certificate Account invested in Eligible Investments as set forth in subsection (c) below, and to make payments to itself prior to making distributions pursuant to Section 5.02 for any expenses or other indemnification owing to the Trustee and others pursuant to any provision of this Agreement or the Custodial Agreements;

(iii) to make payments of the Master Servicing Fee (to the extent not already withheld or withdrawn from the Collection Account by the Master Servicer) to the Master Servicer;

(iv) to make distributions to the Certificateholders pursuant to Article V; and

(v) to clear and terminate the Certificate Account pursuant to Section 7.02.

(c) The Trustee may invest, or cause to be invested, funds held in the Certificate Account, which funds, if invested, shall be invested in Eligible Investments (which may be obligations of the Trustee described in paragraph (viii) of the definition thereof). All such investments must be payable on demand or mature no later than the next Distribution Date, and shall not be sold or disposed of prior to their maturity. All such Eligible Investments will be made in the name of the Trustee (in its capacity as such) or its nominee. All income and gain realized from any such investment shall be compensation for the Trustee and shall be subject to its withdrawal on order from time to time. The amount of any losses incurred in respect of any such investments shall be paid by the Trustee for deposit in the Certificate Account out of its own funds, without any right of reimbursement therefor, immediately as realized. Funds held in the Certificate Account that are not invested shall be held in cash.

Section 5.01. Distributions Generally.

(a) Subject to Section 7.01 respecting the final distribution on the Certificates, on each Distribution Date the Trustee or the Paying Agent shall make distributions in accordance with this Article V.

Distributions on Book-Entry Certificates shall be made by wire transfer. Notwithstanding such final distribution of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of each REMIC and the payment in full of all other amounts due with respect to the Residual Certificate and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office of the Trustee. If any payment required to be made on the Certificates is to be made on a day that is not a Business Day, then such payment will be made on the next succeeding Business Day.

(b) All distributions or allocations made with respect to Certificateholders within each Class on each Distribution Date shall be allocated among the outstanding Certificates in such Class equally in proportion to their respective initial Certificate Principal Amounts (or initial Notional Amounts).

(ii) from the Available Distribution Amount for each Mortgage Pool, to each Class of Senior Certificates or Components relating to such Mortgage Pool (other than the Class AP Certificates), any related Interest Shortfall for such Distribution Date; provided, however, that any shortfall in available amounts for each Mortgage Pool shall be allocated among the Classes of Senior Certificates or Components related to such Mortgage Pool in proportion to the amount of such interest (as so reduced) that would otherwise be distributable thereon;

(b) Net Prepayment Interest Shortfalls for each Mortgage Pool shall be allocated among the Certificates and Components related to such Mortgage Pool (other than the Class AP Certificates) pro rata based on (i) in the case of the related Non-AP Senior Certificates and Components, the Accrued Certificate Interest otherwise distributable thereon, and (ii) in the case of the Subordinate Certificates, interest accrued on the related Apportioned Principal Balances.

(c) After the Credit Support Depletion Date, the Senior Distribution Amount with respect to Pool 3 remaining after distribution of interest to the related Non-AP Senior Certificates on such date shall be distributed among the related Classes of Senior Certificates proportionately, on the basis of their respective Class Principal Amounts immediately prior to such Distribution Date, regardless of the priorities and amounts set forth in Section 5.02(a)(iii).

Any amount not distributed in respect of any Class on any Distribution Date pursuant to the immediately preceding paragraph shall be allocated among the remaining Classes of Subordinate Certificates in proportion to their respective Class Principal Amounts.

(e) On each Distribution Date, the Trustee shall distribute to the Holder of the Class R Certificate any amounts remaining in the REMIC III for such Distribution Date after application of all amounts described in paragraph (a) of this Section 5.02. Any distributions pursuant to this paragraph (d) shall not reduce the Class Principal Amount of the Class R Certificate.

(g) (i) On each Distribution Date prior to the Credit Support Depletion Date but after the date on which the total Certificate Principal Amount of the Non-AP Senior Certificate or Certificates relating to a Mortgage Pool have been reduced to zero, amounts otherwise distributable as principal on each Class of Subordinate Certificates pursuant to Section 5.02(a)(v), in reverse order of priority, in respect of such Class’s Subordinate Class Percentage of the Subordinate Principal Distribution Amount for the Mortgage Pool relating to such retired Certificates, shall be distributed as principal to the Non-AP Senior Certificates remaining outstanding pursuant to Section 5.02(a)(iii) until the Class Principal Amounts thereof have been reduced to zero, provided that on such Distribution Date (a) the Aggregate Subordinate Percentage for such Distribution Date is less than 200% of the Aggregate Subordinate Percentage as of the Cut-off Date or (b) the average outstanding principal balance of the Mortgage Loans in any Mortgage Pool that are delinquent 60 days or more for the last six months (including for this purpose any REO Property or Mortgage Loans in foreclosure or bankruptcy and the Scheduled Payments that would have been due on Mortgage Loans with respect to which the related Mortgaged Property has been acquired by the Trust Fund if the related Mortgage Loan had remained in existence) as a percentage of the related Group Subordinate Amount is greater than or equal to 50%.

(A) On each Distribution Date on which the Class Principal Amounts of the Non-AP Senior Certificates relating to two or more Mortgage Pools have been reduced to zero, any amounts distributable pursuant to this Section 5.02(g)(i) will be allocated, as to each applicable Class of Subordinate Certificates, in proportion to such Class’s Subordinate Class Percentage of the Subordinate Principal Distribution Amount for the Mortgage Pool relating to each such retired Senior Certificate.

(B) On each Distribution Date on which the Non-AP Senior Certificates for two or more Mortgage Pools remain outstanding, any amounts distributable pursuant to this Section 5.02(f)(i) will be distributed in proportion to the aggregate Certificate Principal Amount of such Certificates relating to each such Mortgage Pool.

(ii) (A) On any Distribution Date on which any Non-AP Senior Certificate or Certificates constitute an Undercollateralized Class or Classes, all amounts otherwise distributable as principal on the Subordinate Certificates, in reverse order of priority (other than amounts necessary to pay any AP Deferred Amounts or unpaid Interest Shortfalls) (or, following the Credit Support Depletion Date, such other amounts described in the immediately following sentence), will be distributed as principal to the Undercollateralized Class or Classes pursuant to Section 5.02(a)(iii), until the total Certificate Principal Amount of the Undercollateralized Class or Classes equals (i) the Pool Balance of Pool 1, in the case of Pool 1 or (ii) the Non-AP Pool Balance of the related Mortgage Pool, in the case of Pool 2, Pool 3 and Pool 4 (such distribution, an “Undercollateralization Distribution”). In the event that any Non-AP Senior Certificate or Certificates constitute an Undercollateralized Class or Classes on any Distribution Date following the Credit Support Depletion Date, Undercollateralization Distributions will be made from any Available Distribution Amount for the Mortgage Pools not related to an Undercollateralized Class or Classes remaining after all required amounts have been distributed to the Non-AP Senior Certificates related to such other Mortgage Pools. In addition, the amount of any unpaid Interest Shortfalls with respect to an Undercollateralized Class on any Distribution Date (including any Interest Shortfalls for such Distribution Date) will be distributed to the Undercollateralized Class or Classes prior to the payment of any Undercollateralization Distributions from amounts otherwise distributable as principal on the Subordinate Certificates, in reverse order of priority (or, following the Credit Support Depletion Date, as provided in the preceding sentence).

(B) If on any Distribution Date the Non-AP Senior Certificates relating to more than one Mortgage Pool are Undercollateralized Classes, the distribution described in paragraph (ii)(A) above will be made in proportion to the amount by which the total Certificate Principal Amount of the Non-AP Senior Certificate or Certificates relating to each Mortgage Pool, after giving effect to distributions pursuant to Sections 5.02(a) and 5.02(b) on such Distribution Date, exceeds (i) the Pool Balance Pool 1 for such Distribution Date, in the case of Pool 1 or (ii) the Non-AP Pool Balance for the related Mortgage Pool for such Distribution Date, in the case of Pool 2, Pool 3 and Pool 4.

Section 5.03. Allocation of Realized Losses.

(a) (i) On any Distribution Date, (x) the applicable AP Percentage of the principal portion of each Realized Loss (other than any Excess Loss) in respect of a Discount Mortgage Loan in Pool 2 will be allocated to and reduce the Class Principal Amount of the Class 2-AP Certificates until its Class Principal Amount has been reduced to zero, and the applicable AP Percentage of the principal portion of each Realized Loss (other than any Excess Loss) in respect of a Discount Mortgage Loan in Pool 3 will be allocated to and reduce the Class Principal Amount of the Class 3-AP Certificates until its Class Principal Amount has been reduced to zero; and (y) (i) the principal portion of each Realized Loss (other than any Excess Loss) in respect of a Mortgage Loan in Pool 1 or (ii) the applicable Non-AP Percentage of the principal portion of each Realized Loss (other than any Excess Loss) in respect of a Mortgage Loan in Pool 2, Pool 3 or Pool 4, shall be allocated in the following order of priority:

second, to the Class B5 Certificates, in reduction of their Class Principal Amount, until the Class Principal Amount thereof has been reduced to zero;

third, to the Class B4 Certificates, in reduction of their Class Principal Amount, until the Class Principal Amount thereof has been reduced to zero;

fifth, to the Class B2 Certificates, in reduction of their Class Principal Amount, until the Class Principal Amount thereof has been reduced to zero;

sixth, to the Class B1 Certificates, in reduction of their Class Principal Amount, until the Class Principal Amount thereof has been reduced to zero; and

seventh, to the related Classes of Non-AP Senior Certificates, pro rata, in accordance with their respective Class Principal Amounts; provided, however, that any Realized Loss that would otherwise be allocated to the Class 3-A1 Certificate will be allocated to the Class 3-A8 Certificates until the Class Principal Amount of the Class 3-A8 Certificates has been reduced to zero.

(b) With respect to any Distribution Date, (i) the principal portion of any Excess Loss in respect of a Mortgage Loan in Pool 1 or (ii) the applicable Non-AP Percentage of the principal portion of any Excess Loss in respect of a Mortgage Loan in Pool 2, Pool 3 or Pool 4, shall be allocated, pro rata, to the Subordinate Certificates and related Non-AP Senior Certificate or Certificates on the basis of the Apportioned Principal Balances of the Classes of Subordinate Certificates and Class Principal Amounts of the Non-AP Senior Certificates. The applicable AP Percentage of the principal portion of an Excess Loss (other than a Debt Service Reduction) in respect of a Mortgage Loan in Pool 2 and Pool 3 will be applied to the Class 2-AP Certificates and the Class 3-AP Certificates, respectively, until the Class Principal Amounts thereof have been reduced to zero.

(c) Any Realized Losses allocated to a Class of Certificates pursuant to Section 5.03(a) or (b) shall be allocated among the Certificates of such Class in proportion to their respective Certificate Principal Amounts. Any allocation of Realized Losses pursuant to this paragraph (c) shall be accomplished by reducing the Certificate Principal Amounts of the related Certificates on the related Distribution Date in accordance with Section 5.03(d).

(d) Realized Losses allocated in accordance with this Section 5.03 shall be allocated on the Distribution Date in the month following the month in which such loss was incurred and, in the case of the principal portion thereof, after giving effect to distributions made on such Distribution Date, except that the aggregate amount of Realized Losses to be allocated to the Class AP Certificates on such Distribution Date will be taken into account in determining distributions in respect of any related AP Deferred Amount for such date.

(e) On each Distribution Date, the Subordinate Certificate Writedown Amount for such date shall effect a corresponding reduction in the Class Principal Amount of the lowest ranking Class of outstanding Subordinate Certificates, which reduction shall occur on such Distribution Date after giving effect to distributions made on such Distribution Date.

Section 5.04. Advances by the Master Servicer and the Trustee.

(a) Advances shall be made in respect of each Deposit Date as provided herein. If, on any Determination Date, the Master Servicer determines that any Scheduled Payments due during the related Due Period (other than Balloon Payments) have not been received, the Master Servicer shall, or cause the applicable Servicer to, advance such amount, less an amount, if any, to be set forth in an Officer’s Certificate to be delivered to the Trustee on such Determination Date, which if advanced the Master Servicer or the applicable Servicer has determined would not be recoverable from amounts received with respect to such Mortgage Loan, including late payments, Liquidation Proceeds, Insurance Proceeds or otherwise. If the Master Servicer determines that an Advance is required, it shall on the Deposit Date immediately following such Determination Date either (i) remit to the Trustee from its own funds (or funds advanced by the applicable Servicer) for deposit in the Certificate Account immediately available funds in an amount equal to such Advance, (ii) cause to be made an appropriate entry in the records of the Collection Account that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 5.04, used by the Master Servicer to make such Advance, and remit such immediately available funds to the Trustee for deposit in the Certificate Account or (iii) make Advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any funds being held in the Collection Account for future distribution to Certificateholders and so used shall be replaced by the Master Servicer from its own funds by remittance to the Trustee for deposit in the Certificate Account on or before any future Deposit Date to the extent that funds in the Certificate Account on such Deposit Date shall be less than payments to Certificateholders required to be made on the related Distribution Date. The Trustee shall be entitled to conclusively rely upon any determination by the Master Servicer that an Advance, if made, would constitute a non-recoverable advance. The Master Servicer and each Servicer shall be entitled to be reimbursed from the Collection Account for all Advances made by it as provided in Section 4.02.

(b) In the event that the Master Servicer fails for any reason to make an Advance required to be made pursuant to this Section 5.04, the Trustee, solely in its capacity as successor Master Servicer pursuant to Section 6.14, shall, on or before the related Distribution Date, deposit in the Certificate Account an amount equal to the excess of (a) Advances required to be made by the Master Servicer that would have been deposited in such Certificate Account over (b) the amount of any Advance made by the Master Servicer and Servicers with respect to such Distribution Date; provided, however, that the Trustee shall be required to make such Advance only if it is not prohibited by law from doing so and it has determined that such Advance would be recoverable from amounts to be received with respect to such Mortgage Loan, including late payments, Liquidation Proceeds, Insurance Proceeds, or otherwise. The Trustee shall be entitled to be reimbursed from the Certificate Account for Advances made by it pursuant to this Section 5.04 as if it were the Master Servicer.

Section 5.05. Compensating Interest Payments.

The Master Servicer shall not be responsible for making any Compensating Interest Payments not made by the Servicers. Any Compensating Interest Payments made by the Servicers shall be a component of the Available Distribution Amount.

ARTICLE VI

CONCERNING THE TRUSTEE;

EVENTS OF DEFAULT

Section 6.01. Duties of Trustee.

(a) The Trustee, except during the continuance of an Event of Default (of which a Responsible Officer of the Trustee shall have actual knowledge), undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. Any permissive right of the Trustee provided for in this Agreement shall not be construed as a duty of the Trustee. If an Event of Default (of which a Responsible Officer of the Trustee shall have actual knowledge) has occurred and has not otherwise been cured or waived, the Trustee shall exercise such of the rights and powers vested in it by this Agreement and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs unless the Trustee is acting as Master Servicer, in which case it shall use the same degree of care and skill as the Master Servicer hereunder.

(b) The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they are in the form required by this Agreement; provided, however, that the Trustee shall not be responsible for the accuracy or content of any such resolution, certificate, statement, opinion, report, document, order or other instrument furnished by the Master Servicer to the Trustee pursuant to this Agreement, and the Trustee shall not be required to recalculate or verify any numerical information furnished to the Trustee pursuant to this Agreement.

(c) The Trustee shall not have any liability arising out of or in connection with this Agreement, except for its negligence or willful misconduct. No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that:

As compensation therefor, the Trustee shall be entitled to receive all compensation payable to the Master Servicer under this Agreement, including the Master Servicing Fee.

(c) Notwithstanding the above, the Trustee may, if it shall be unwilling to continue to so act, or shall, if it is unable to so act, appoint a successor Master Servicer or petition a court of competent jurisdiction to appoint, any established housing and home finance institution servicer, master servicer, servicing or mortgage servicing institution having a net worth of not less than $15,000,000 and meeting such other standards for a successor master servicer as are set forth in this Agreement, as the successor to such Master Servicer in the assumption of all of the responsibilities, duties or liabilities of a master servicer, like the Master Servicer. Any entity designated by the Trustee as a successor master servicer may be an Affiliate of the Trustee, provided, however, that, unless such Affiliate meets the net worth requirements and other standards set forth herein for a successor master servicer or the Trustee, in its individual capacity shall agree, at the time of such designation, to be and remain liable to the Trust Fund for such Affiliate’s actions and omissions in performing its duties hereunder. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted to the Master Servicer hereunder. The Trustee and such successor shall take such actions, consistent with this Agreement, as shall be necessary to effectuate any such succession and may make other arrangements with respect to the servicing to be conducted hereunder which are not inconsistent herewith. The Master Servicer shall cooperate with the Trustee, and any successor master servicer in effecting the termination of the Master Servicer’s responsibilities and rights hereunder including, without limitation, notifying Mortgagors of the assignment of the master servicing functions and providing the Trustee and successor master servicer, as applicable, all documents and records in electronic or other form reasonably requested by it to enable it to assume the Master Servicer’s functions hereunder and the transfer to the Trustee or such successor master servicer, as applicable, all amounts which shall at the time be or should have been deposited by the Master Servicer in the Collection Account and any other account or fund maintained with respect to the Certificates or thereafter be received with respect to the Mortgage Loans. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (i) the failure of the Master Servicer to deliver, or any delay in delivering, cash, documents or records to it, (ii) the failure of the Master Servicer to cooperate as required by this Agreement, (iii) the failure of the Master Servicer to deliver the Mortgage Loan data to the Trustee as required by this Agreement or (iv) restrictions imposed by any regulatory authority having jurisdiction over the Master Servicer. The Trustee shall be entitled to be reimbursed from 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 master servicing from the predecessor Master Servicer, including, without limitation, any costs or expenses associated with the complete transfer of all master servicing data and the completion, correction or manipulation of such master servicing data as may be required by the Trustee to correct any errors or insufficiencies in the master servicing data or otherwise to enable the Trustee to master service the Mortgage Loans properly and effectively. If the terminated Master Servicer does not pay such reimbursement within thirty (30) days of its receipt of an invoice therefor, such reimbursement shall be an expense of the Trust Fund and the Trustee shall be entitled to withdraw such reimbursement from amounts on deposit in the Certificate Account pursuant to Section 4.04; provided that the terminated Master Servicer shall reimburse the Trust for any such expense incurred by the Trust Fund.

Section 6.15. Additional Remedies of Trustee Upon Event of Default.

During the continuance of any Event of Default, so long as such Event of Default shall not have been remedied, the Trustee, in addition to the rights specified in Section 6.14, shall have the right, in its own name and as trustee of an express trust, to take all actions now or hereafter existing at law, in equity or by statute to enforce its rights and remedies and to protect the interests, and enforce the rights and remedies, of the Certificateholders (including the institution and prosecution of all judicial, administrative and other proceedings and the filings of proofs of claim and debt in connection therewith). Except as otherwise expressly provided in this Agreement, no remedy provided for by this Agreement shall be exclusive of any other remedy, and each and every remedy shall be cumulative and in addition to any other remedy, and no delay or omission to exercise any right or remedy shall impair any such right or remedy or shall be deemed to be a waiver of any Event of Default.

Section 6.16. Waiver of Defaults.

35% or more of the Aggregate Voting Interests of Certificateholders may waive any default or Event of Default by the Master Servicer in the performance of its obligations hereunder, except that a default in the making of any required deposit to the Certificate Account that would result in a failure of the Trustee to make any required payment of principal of or interest on the Certificates may only be waived with the consent of 100% of the affected Certificateholders. Upon any such waiver of a past default, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived.

Section 6.17. Notification to Holders.

Upon termination of the Master Servicer or appointment of a successor to the Master Servicer, in each case as provided herein, the Trustee shall promptly mail notice thereof by first class mail to the Certificateholders at their respective addresses appearing on the Certificate Register. The Trustee shall also, within 45 days after the occurrence of any Event of Default known to a Responsible Officer of the Trustee, give written notice thereof to the Certificateholders, unless such Event of Default shall have been cured or waived prior to the issuance of such notice and within such 45-day period.

Section 6.18. Directions by Certificateholders and Duties of Trustee During Event of Default.

Subject to the provisions of Section 8.01 hereof, during the continuance of any Event of Default, Holders of Certificates evidencing not less than 25% of the Class Principal Amount (or Class Notional Amount) of each Class of Certificates may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement; provided, however, that the Trustee shall be under no obligation to pursue any such remedy, or to exercise any of the trusts or powers vested in it by this Agreement (including, without limitation, (i) the conducting or defending of any administrative action or litigation hereunder or in relation hereto and (ii) the terminating of the Master Servicer or any successor master servicer from its rights and duties as master servicer hereunder) at the request, order or direction of any of the Certificateholders, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity against the cost, expenses and liabilities which may be incurred therein or thereby; and, provided, further, that, subject to the provisions of Section 8.01, the Trustee shall have the right to decline to follow any such direction if the Trustee, in accordance with an Opinion of Counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith determines that the action or proceeding so directed would involve it in personal liability or be unjustly prejudicial to the non-assenting Certificateholders.

Section 6.19. Action Upon Certain Failures of the Master Servicer and Upon Event of Default.

In the event that a Responsible Officer of the Trustee shall have actual knowledge of any action or inaction of the Master Servicer that would become an Event of Default upon the Master Servicer’s failure to remedy the same after notice, the Trustee shall give notice thereof to the Master Servicer. For all purposes of this Agreement, in the absence of actual knowledge by a Responsible Officer of the Trustee, the Trustee shall not be deemed to have knowledge of any failure of the Master Servicer or any other Event of Default unless notified in writing by the Depositor, the Master Servicer or a Certificateholder.

Section 6.20. Preparation of Tax Returns and Other Reports.

(a) The Trustee shall prepare or cause to be prepared on behalf of the Trust Fund, based upon information calculated in accordance with this Agreement pursuant to instructions given by the Depositor, and the Trustee shall file, federal tax returns and appropriate state income tax returns and such other returns as may be required by applicable law relating to the Trust Fund, and shall file any other documents to the extent required by applicable state tax law (to the extent such documents are in the Trustee’s possession). The Trustee shall forward copies to the Depositor of all such returns and Form 1099 supplemental tax information and such other information within the control of the Trustee as the Depositor may reasonably request in writing, and shall forward to each Certificateholder such forms and furnish such information within the control of the Trustee as are required by the Code and the REMIC Provisions to be furnished to them, and will prepare and distribute to Certificateholders Form 1099 (supplemental tax information) (or otherwise furnish information within the control of the Trustee) to the extent required by applicable law. The Master Servicer will indemnify the Trustee for any liability of or assessment against the Trustee resulting from any error in any of such tax or information returns directly resulting from errors in the information provided by such Master Servicer.

(b) The Trustee shall prepare and file with the Internal Revenue Service (“IRS”), on behalf of each REMIC, an application on IRS Form SS-4. The Trustee upon receipt from the IRS of the Notice of Taxpayer Identification Number Assigned for each REMIC, shall promptly forward copies of such notices to the Master Servicer and the Depositor. The Trustee will file an IRS Form 8811.

(c) The Depositor shall prepare or cause to be prepared the initial current report on Form 8-K. Thereafter, within 10 days (or, if applicable, within such shorter period of time as is required under the rules of the Commission as in effect from time to time (the “Rules”)) following each Distribution Date, the Trustee shall, in accordance with industry standards and the Rules, prepare and file with the Commission via the Electronic Data Gathering and Retrieval System (XXXXX), a Form 8-K (or such other form as is prescribed by the Rules) that includes (i) a copy of the statement to the Certificateholders for such Distribution Date and (ii) such other information as is required by the Rules. Unless the Trustee receives written notice prior to January 15, 2005 not to do so, prior to January 30, 2005, the Trustee shall, in accordance with industry standards, prepare and file a Form 15 Suspension Notification with respect to the Trust Fund, if applicable. If so directed by the Depositor, the Trustee shall, at monthly intervals or such other less frequent intervals as are specified by the Depositor, file with the Commission via XXXXX pursuant to Rule 424 under the Act a prospectus supplement prepared by the Depositor that includes (i) a cover page in the form provided by the Depositor, (ii) a copy of the statement to the Certificateholders for the most recent Distribution Date, and (iii) such other information as is provided by the Depositor. Prior to March 30, 2005 and, unless and until a Form 15 Suspension Notification shall have been filed, on or prior to March 30 of each year thereafter, the Trustee shall file (but will not execute) a Form 10-K, in substance conforming to industry standards and complying with the Rules, with respect to the Trust Fund. Each Form 10-K shall include the certification required pursuant to Rule 13a-14 under the Exchange Act (the “Form 10-K Certification”) signed by an appropriate party or parties (which Form 10-K Certification the Trustee shall not be required to prepare or sign) and such other information as is required by the Rules. The Trustee shall promptly send copies of each periodic report filed on Form 8-K or other applicable form, each annual report on Form 10-K, and each Form 15 Suspension Notification, together in each case with the acceptance confirmation receipt from XXXXX, to XxXxx Xxxxxx LLP and to the Depositor (i) by e-mail to the e-mail addresses provided in writing by each of XxXxx Xxxxxx LLP and the Depositor, respectively and (ii) to XxXxx Xxxxxx LLP at 0000 X Xxxxxx, X.X., Xxxxxxxxxx, X.X. 00000, and to the Depositor at the address specified in Section 11.07, in each case to the attention of a designated contact specified by each of XxXxx Xxxxxx LLP and the Depositor, respectively. The Trustee shall not have any liability for any delay in filing the Form 10-K or Form 10-K Certification due to the failure of any party to timely sign such Form 10-K or Form 10-K Certification. The Depositor hereby grants to the Trustee a limited power of attorney to execute and file each Form 8-K (or other applicable form for filing of periodic reports) and, if applicable, each prospectus supplement to be filed pursuant to Rule 424, on behalf of the Depositor. Such power of attorney shall continue until either the earlier of (i) receipt by the Trustee from the Depositor of written termination of such power of attorney or (ii) the termination of the Trust Fund. The Depositor agrees to promptly furnish to the Trustee, from time to time upon request, such further information, reports, and financial statements within its control related to this Agreement and the Mortgage Loans as the Trustee reasonably deems appropriate to prepare and file all necessary reports with the Commission. The Trustee shall have no responsibility to file any items other than those specified in this section. The Depositor agrees to cooperate with the Trustee and Trustee’s counsel to assist the Trustee in determining the form and content of any filings that may be required pursuant to this Section 6.20(c) and, without limiting the Trustee’s responsibility hereunder, otherwise to assist the Trustee in fulfilling its duties under this Section 6.20(c).

(d) If so requested, the Trustee shall sign a certification (in the form attached hereto as Exhibit Q for the benefit of the Person(s) signing the Form 10-K Certification regarding certain aspects of such Form 10-K Certification (provided, however, that the Trustee shall not be required to undertake an analysis of, and shall have no responsibility for, any financial information, accountant’s report, certification or other matter contained therein, except for computations performed by the Trustee and reflected in distribution reports. Nothing in this Section 6.20(d) shall relieve the Trustee of its responsibility for the matters as to which it is certifying in the form attached hereto as Exhibit Q.

(e) Each person (including their officers or directors) that signs any Form 10-K Certification shall be entitled to indemnification from the Trust Fund for any liability or expense incurred by it in connection with such certification, other than any liability or expense attributable to such Person’s own bad faith, negligence or willful misconduct. The provisions of this subsection shall survive any termination of this Agreement and the resignation or removal of such Person.

Section 6.21 Reporting Requirements of the Commission.

The Trustee and the Master Servicer shall reasonably cooperate with the Depositor and its counsel to enter into such amendments or modifications to this Agreement as may be necessary to comply with the Rules and any interpretations thereof by the staff of the Commission, subject to the provisions of Section 11.03 hereof.

PURCHASE AND TERMINATION

OF THE TRUST FUND

Section 7.01. Termination of Trust Fund Upon Repurchase or Liquidation of All Mortgage Loans.

(a) The respective obligations and responsibilities of the Trustee and the Master Servicer created hereby (other than the obligation of the Trustee to make payments to Certificateholders as set forth in Section 7.02, the obligation of the Master Servicer to make a final remittance to the Trustee for deposit into the Certificate Account pursuant to Section 4.01 and the obligations of the Master Servicer to the Trustee pursuant to Sections 9.10 and 9.14), shall terminate on the earlier of (i) the final payment or other liquidation of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property and (ii) the sale of the property held by the Trust Fund in accordance with Section 7.01(b); provided, however, that in no event shall the Trust Fund created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Xxxxxx X. Xxxxxxx, the late Ambassador of the United States to the Court of St. James’s, living on the date hereof or beyond the Latest Possible Maturity Date. Any termination of the Trust Fund shall be carried out in such a manner so that the termination of each REMIC included therein shall qualify as a “qualified liquidation” under the REMIC Provisions.

(b) On any Distribution Date occurring after the date on which the aggregate Scheduled Principal Balance of the Mortgage Loans is less than 10% of the Cut-off Date Aggregate Principal Balance, the Master Servicer may, upon written direction to the Trustee (delivered no later than 30 days prior to the anticipated sale date), cause (i) the Trustee to sell (or arrange for the sale of) the assets of the Trust Fund and (ii) the Trust Fund to adopt a plan of complete liquidation pursuant to Section 7.03(a)(i) hereof to sell all of its property. The property of the Trust Fund shall be sold at a price (the “Termination Price”) equal to the sum of : (i) 100% of the unpaid principal balance of each Mortgage Loan on the day of such purchase plus interest accrued thereon at the applicable Mortgage Rate with respect to any Mortgage Loan to the Due Date in the Due Period immediately preceding the related Distribution Date to the date of such repurchase, (ii) the fair market value of any REO Property and any other property held by any REMIC, such fair market value to be determined by an appraiser or appraisers appointed by the Master Servicer and reasonably acceptable to the Trustee and (iii) any unreimbursed Servicing Advances with respect to each Mortgage Loan.

Section 7.02. Procedure Upon Termination of Trust Fund.

(a) Notice of any termination pursuant to the provisions of Section 7.01, specifying the Distribution Date upon which the final distribution shall be made, shall be given promptly by the Trustee by first class mail to Certificateholders mailed (x) no later than five Business Days after the Trustee has received notice from the Master Servicer of its intent to exercise its right to cause the termination of the Trust Fund pursuant to Section 7.01(b) or (y) upon the final payment or other liquidation of the last Mortgage Loan or REO Property in the Trust Fund. Such notice shall specify (A) the Distribution Date upon which final distribution on the Certificates of all amounts required to be distributed to Certificateholders pursuant to Section 5.02 will be made upon presentation and surrender of the Certificates at the Corporate Trust Office, and (B) that the Record Date otherwise applicable to such Distribution Date is not applicable, distribution being made only upon presentation and surrender of the Certificates at the office or agency of the Trustee therein specified. The Trustee shall give such notice to the Master Servicer and the Certificate Registrar at the time such notice is given to Holders of the Certificates. Upon any such termination, the duties of the Certificate Registrar with respect to the Certificates shall terminate and the Trustee shall terminate, or request the Master Servicer to terminate, the Collection Account it maintains, the Certificate Account and any other account or fund maintained with respect to the Certificates, subject to the Trustee’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment.

(b) In the event that all of the Holders do not surrender their Certificates for cancellation within three months after the time specified in the above-mentioned written notice, the Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within one year after the second notice any Certificates shall not have been surrendered for cancellation, the Trustee may take appropriate steps to contact the remaining Certificateholders concerning surrender of such Certificates, and the cost thereof shall be paid out of the amounts distributable to such Holders. If within two years after the second notice any Certificates shall not have been surrendered for cancellation, the Trustee shall, subject to applicable state law relating to escheatment, hold all amounts distributable to such Holders for the benefit of such Holders. No interest shall accrue on any amount held by the Trustee and not distributed to a Certificateholder due to such Certificateholder’s failure to surrender its Certificate(s) for payment of the final distribution thereon in accordance with this Section.

(c) Any reasonable expenses incurred by the Trustee in connection with any termination or liquidation of the Trust Fund shall be reimbursed from proceeds received from the liquidation of the Trust Fund.

Section 7.03. Additional Trust Fund Termination Requirements.

(a) Any termination of the Trust Fund shall be effected in accordance with the following additional requirements, unless the Trustee seeks (at the request of the Master Servicer), and subsequently receives, an Opinion of Counsel (at the expense of the Master Servicer), addressed to the Trustee to the effect that the failure of the Trust Fund to comply with the requirements of this Section 7.03 will not (i) result in the imposition of taxes on any REMIC under the REMIC Provisions or (ii) cause any REMIC established hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(i) The Trustee shall sell all of the assets of the Trust Fund for cash and, within 90 days of such sale, shall distribute the proceeds of such sale to the Certificateholders in complete liquidation of the Trust Fund and each REMIC created hereunder; and

(ii) The Trustee shall attach a statement to the final Federal income tax return for each of the REMICs created hereunder stating that pursuant to Treasury Regulation § 1.860F-1, the first day of the 90-day liquidation period for each such REMIC was the date on which the Trustee sold the assets of the Trust Fund.

(b) By its acceptance of a Residual Certificate, each Holder thereof hereby (i) authorizes the Trustee to take the action described in paragraph (a) above and (ii) agrees to take such other action as may be necessary to facilitate liquidation of each REMIC created under this Agreement, which authorization shall be binding upon all successor Residual Certificateholders.

ARTICLE VIII

RIGHTS OF CERTIFICATEHOLDERS

Section 8.01. Limitation on Rights of Holders.

(a) The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or this Trust Fund, nor entitle such Certificateholder’s legal representatives or heirs to claim an accounting or take any action or proceeding in any court for a partition or winding up of this Trust Fund, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them. Except as otherwise expressly provided herein, no Certificateholder, solely by virtue of its status as a Certificateholder, shall have any right to vote or in any manner otherwise control the Master Servicer or the operation and management of the Trust Fund, or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of the Certificates, be construed so as to constitute the Certificateholders from time to time as partners or members of an association, nor shall any Certificateholder be under any liability to any third person by reason of any action taken by the parties to this Agreement pursuant to any provision hereof.

(b) No Certificateholder, solely by virtue of its status as Certificateholder, shall have any right by virtue or by availing of any provision of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of Certificates evidencing not less than 25% of the Class Principal Amount (or Class Notional Amount) of Certificates of each Class shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the cost, expenses and liabilities to be incurred therein or thereby, and the Trustee, for sixty days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request has been given such Trustee during such sixty-day period by such Certificateholders; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Agreement, except in the manner herein provided and for the benefit of all Certificateholders.

(b) If three or more Holders or Certificate Owners (hereinafter referred to as “Applicants”) apply in writing to the Trustee, and such application states that the Applicants desire to communicate with other Holders with respect to their rights under this Agreement or under the Certificates and is accompanied by a copy of the communication which such Applicants propose to transmit, then the Trustee shall, within five Business Days after the receipt of such application, afford such Applicants reasonable access during the normal business hours of the Trustee to the most recent list of Certificateholders held by the Trustee or shall, as an alternative, send, at the Applicants’ expense, the written communication proffered by the Applicants to all Certificateholders at their addresses as they appear in the Certificate Register.

(c) Every Holder or Certificate Owner, if the Holder is a Clearing Agency, by receiving and holding a Certificate, agrees with the Depositor, the Master Servicer, the Certificate Registrar and the Trustee that neither the Depositor, the Master Servicer, the Certificate Registrar nor the Trustee shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 8.03. Acts of Holders of Certificates.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by Holders or Certificate Owner, if the Holder is a Clearing Agency, may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where expressly required herein, to the Master Servicer. Such instrument or instruments (as the action embodies therein and evidenced thereby) are herein sometimes referred to as an “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agents shall be sufficient for any purpose of this Agreement and conclusive in favor of the Trustee and Master Servicer, if made in the manner provided in this Section. Each of the Trustee and the Master Servicer shall promptly notify the others of receipt of any such instrument by it, and shall promptly forward a copy of such instrument to the others.

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

(c) The ownership of Certificates (whether or not such Certificates shall be overdue and notwithstanding any notation of ownership or other writing thereon made by anyone other than the Trustee) shall be proved by the Certificate Register, and neither the Trustee, the Master Servicer, nor the Depositor shall be affected by any notice to the contrary.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Certificate shall bind every future Holder of the same Certificate and the Holder of every Certificate issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, in respect of anything done, omitted or suffered to be done by the Trustee or the Master Servicer in reliance thereon, whether or not notation of such action is made upon such Certificate.

The Errors and Omissions Insurance Policy and the Fidelity Bond shall be in such form and amount that would meet the requirements of FNMA or FHLMC if it were the purchaser of the Mortgage Loans. The Master Servicer shall (i) require each Servicer to maintain an Errors and Omissions Insurance Policy and a Fidelity Bond in accordance with the provisions of the applicable Servicing Agreement, (ii) cause each Servicer to provide to the Master Servicer certificates evidencing that such policy and bond is in effect and to furnish to the Master Servicer any notice of cancellation, non-renewal or modification of the policy or bond received by it, as and to the extent provided in the applicable Servicing Agreement, and (iii) furnish copies of the certificates and notices referred to in clause (ii) to the Trustee upon its request. The Fidelity Bond and Errors and Omissions Insurance Policy may be obtained and maintained in blanket form.

(b) The Master Servicer shall promptly report to the Trustee any material changes that may occur in the Master Servicer Fidelity Bond or the Master Servicer Errors and Omissions Insurance Policy and shall furnish to the Trustee, on request, certificates evidencing that such bond and insurance policy are in full force and effect. The Master Servicer shall promptly report to the Trustee all cases of embezzlement or fraud, if such events involve funds relating to the Mortgage Loans.

(a) The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article X hereof, and each Servicer shall have full power and authority (to the extent provided in the applicable Servicing Agreement) to do any and all things that it may deem necessary or desirable in connection with the servicing and administration of the Mortgage Loans, including but not limited to the power and authority (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, in each case, in accordance with the provisions of this Agreement and applicable Servicing Agreement, as applicable; provided that the Master Servicer shall not take, or knowingly permit any Servicer to take, any action that is inconsistent with or prejudices the interests of the Trust Fund, the Trustee or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee and the Certificateholders under this Agreement. The Master Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of any Servicer, when the Master Servicer or a Servicer, as the case may be, believes it is appropriate in its best judgment to register any Mortgage Loan with MERS, or cause the removal from the registration of any Mortgage Loan on the MERS system, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns. The Master Servicer shall represent and protect the interests of the Trust Fund in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan and shall not make or knowingly permit any Servicer to make any modification, waiver or amendment of any term of any Mortgage Loan that would cause any REMIC formed hereby to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code. Without limiting the generality of the foregoing, the Master Servicer in its own name or in the name of a Servicer, and each Servicer, to the extent such authority is delegated to such Servicer by the Master Servicer under the applicable Servicing Agreement, is hereby authorized and empowered by the Trustee when the Master Servicer or applicable Servicer, as the case may be, believes it appropriate in its best judgment and in accordance with Accepted Servicing Practices and the applicable Servicing Agreement, to execute and deliver, on behalf of itself and the Certificateholders, the Trustee or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to the Mortgage Loans and with respect to the Mortgaged Properties. The Trustee shall execute, upon request, any powers of attorney furnished to it by the Master Servicer empowering the Master Servicer or any Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, necessary or appropriate to enable the Master Servicer to master service the Mortgage Loans and carry out its duties hereunder, and allow each Servicer to service the Mortgage Loans in each case in accordance with Accepted Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Master Servicer or any Servicer). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, then upon request of the Trustee, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 6.09 hereof. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action in the name of the Trustee, be deemed to be the agent of the Trustee.

(b) In master servicing and administering the Mortgage Loans, the Master Servicer shall employ procedures and exercise the same care that it customarily employs and exercises in master servicing and administering loans for its own account, giving due consideration to Accepted Servicing Practices where such practices do not conflict with this Agreement. Consistent with the foregoing, the Master Servicer may, and may permit any Servicer to, in its discretion (i) waive any late payment charge or any prepayment charge or penalty interest in connection with the prepayment of a Mortgage Loan and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 120 days; provided, however, that the maturity of any Mortgage Loan shall not be extended past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any extension described in clause (ii) above, the Master Servicer shall make or cause to be made Advances on the related Mortgage Loan in accordance with the provisions of Section 5.04 on the basis of the amortization schedule of such Mortgage Loan without modification thereof by reason of such extension. Notwithstanding anything to the contrary in this Agreement, the Master Servicer shall not make or knowingly permit any modification, waiver or amendment of any material term of any Mortgage Loan unless: (1) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the applicable Servicer, reasonably foreseeable, (2) in the case of a waiver of a Prepayment Premium if (a) such Mortgage Loan is in default or default by the related Mortgagor is reasonably foreseeable, and such waiver would maximize recovery of total proceeds taking into account the value of such Prepayment Premium and the related Mortgage Loan or (b) if the prepayment is not the result of a refinance by the Servicer or any of its affiliates and (i) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the applicable Servicer, reasonably foreseeable, and such waiver would maximize recovery of total proceeds taking into account the value of such Prepayment Premium and the related Mortgage Loan or (ii) the collection of the Prepayment Premium would be in violation of applicable laws or (iii) the collection of such Prepayment Premium would be considered "predatory" pursuant to written guidance published or issued by any applicable federal, state or local regulatory authority acting in its official capacity and having jurisdiction over such matters, and (3) the Master Servicer shall have provided or caused to be provided to the Trustee an Opinion of Counsel(which opinion shall, if provided by the Master Servicer, be an expense reimbursed from the Collection Account pursuant to Section 4.02(v)) in writing to the effect that such modification, waiver or amendment would not cause an Adverse REMIC Event; provided, in no event shall an Opinion of Counsel be required for the waiver of a Prepayment Premium under clause (2) above. Notwithstanding anything to the contrary, the Master Servicer shall not without the Trustee’s written consent: (i) initiate any action, suit or proceeding solely under the Trustee’s name without indicating the Master Servicer’s representative capacity or (ii) take any action with the intent to cause, and which actually does cause, the Trustee to be registered to do business in any state.

Section 9.05. Servicing Agreements Between the Master Servicer and Servicers; Enforcement of Servicers’ Obligations.

(a) Each Servicing Agreement requires the applicable Servicer to service the Mortgage Loans in accordance with the provisions thereof. References in this Agreement to actions taken or to be taken by the Master Servicer include such actions taken or to be taken by a Servicer pursuant to a Servicing Agreement. Any fees, costs and expenses and other amounts payable to such Servicers shall be deducted from amounts remitted to the Master Servicer by the applicable Servicer (to the extent permitted by the applicable Servicing Agreement) and shall not be an obligation of the Trust Fund, the Trustee or the Master Servicer.

(b) The Master Servicer shall not be required to (i) take any action with respect to the servicing of any Mortgage Loan that the related Servicer is not required to take under the related Servicing Agreement and (ii) cause a Servicer to take any action or refrain from taking any action if the related Servicing Agreement does not require the Servicer to take such action or refrain from taking such action; in both cases notwithstanding any provision of this Agreement that requires the Master Servicer to take such action or cause the Servicer to take such action.

(c) The Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Servicer under the related Servicing Agreement, and shall use its reasonable best efforts to enforce the obligations of each Servicer under the related Servicing Agreement and shall, upon its obtaining actual knowledge of the failure of a Servicer to perform its obligations in accordance with the related Servicing Agreement, to the extent that the non-performance of any such obligations would have a material adverse effect on a Mortgage Loan, the Trust Fund or Certificateholders terminate the rights and obligations of such Servicer thereunder to the extent and in the manner permitted by the related Servicing Agreement and either act as servicer of the related Mortgage Loans or enter into a Servicing Agreement with a successor Servicer. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Servicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, and shall be reimbursed therefor initially only (i) from a general recovery resulting from such enforcement only 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, and then, to the extent that such amounts are insufficient to reimburse the Master Servicer for the costs of such enforcement, (iii) from the Collection Account.

Section 9.06. Collection of Taxes, Assessments and Similar Items.

(a) To the extent provided in the applicable Servicing Agreement, the Master Servicer shall cause each Servicer to establish and maintain one or more custodial accounts at a depository institution (which may be a depository institution with which the Master Servicer or any Servicer establishes accounts in the ordinary course of its servicing activities), the accounts of which are insured to the maximum extent permitted by the FDIC (each, an “Escrow Account”) and shall deposit therein any collections of amounts received with respect to amounts due for taxes, assessments, water rates, Standard Hazard Insurance Policy premiums or any comparable items for the account of the Mortgagors. Withdrawals from any Escrow Account may be made (to the extent amounts have been escrowed for such purpose) only in accordance with the applicable Servicing Agreement. Each Servicer shall be entitled to all investment income not required to be paid to Mortgagors on any Escrow Account maintained by such Servicer. The Master Servicer shall make (or cause to be made) to the extent provided in the applicable Servicing Agreement advances to the extent necessary in order to effect timely payment of taxes, water rates, assessments, Standard Hazard Insurance Policy premiums or comparable items in connection with the related Mortgage Loan (to the extent that the Mortgagor is required, but fails, to pay such items), provided that it has determined that the funds so advanced are recoverable from escrow payments, reimbursement pursuant to Section 4.02(v) or otherwise.

(b) Costs incurred by the Master Servicer or by Servicers in effecting the timely payment of taxes and assessments on the properties subject to the Mortgage Loans may be added to the amount owing under the related Mortgage Note where the terms of the Mortgage Note so permit; provided, however, that the addition of any such cost shall not be taken into account for purposes of calculating the distributions to be made to Certificateholders. Such costs, to the extent that they are unanticipated, extraordinary costs, and not ordinary or routine costs shall be recoverable by the Master Servicer pursuant to Section 4.02(v).

Section 9.07. Termination of Servicing Agreements; Successor Servicers.

(a) The Master Servicer shall be entitled to terminate the rights and obligations of any Servicer under the applicable Servicing Agreement in accordance with the terms and conditions of such Servicing Agreement and without any limitation by virtue of this Agreement; provided, however, that in the event of termination of any Servicing Agreement by the Master Servicer or the related Servicer, the Master Servicer shall either act as Servicer of the related Mortgage Loans, or enter into a Servicing Agreement with a successor Servicer.

(b) If the Master Servicer acts as Servicer, it will not assume liability for the representations and warranties of the Servicer, if any, that it replaces. The Master Servicer shall use reasonable efforts to have the successor Servicer assume liability for the representations and warranties made by the terminated Servicer in respect of the related Mortgage Loans, and in the event of any such assumption by the successor Servicer, the Trustee or the Master Servicer, as applicable, may, in the exercise of its business judgment, release the terminated Servicer from liability for such representations and warranties.

Section 9.08. Master Servicer Liable for Enforcement.

Notwithstanding any Servicing Agreement, the Master Servicer shall remain obligated and liable to the Trustee and the Certificateholders in accordance with the provisions of this Agreement, to the extent of its obligations hereunder, without diminution of such obligation or liability by virtue of such Servicing Agreements or arrangements. The Master Servicer shall use commercially reasonable efforts to ensure that the Mortgage Loans are serviced in accordance with the provisions of this Agreement and shall use commercially reasonable efforts to enforce the provisions of each Servicing Agreement for the benefit of the Certificateholders. The Master Servicer shall be entitled to enter into any agreement with the Servicers for indemnification of the Master Servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification. Except as expressly set forth herein, the Master Servicer shall have no liability for the acts or omissions of any Servicer in the performance by such Servicer of its obligations under the related Servicing Agreement.

Section 9.09. No Contractual Relationship Between Servicers and Trustee or Depositor.

Any Servicing Agreement that may be entered into and any other transactions or services relating to the Mortgage Loans involving a Servicer in its capacity as such and not as an originator shall be deemed to be between such Servicer, the related Seller and the Master Servicer, and except to the extent expressly provided therein the Trustee and the Depositor shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to such Servicer except as set forth in Section 9.10 hereof.

Section 9.10. Assumption of Servicing Agreement by Trustee.

(a) In the event the Master Servicer shall for any reason no longer be the Master Servicer (including by reason of any Event of Default under this Agreement), after a period not to exceed ninety days after the issuance of any notice of termination pursuant to Section 6.14 or Section 9.28, as applicable, the Trustee shall, in accordance with Section 6.14, thereupon assume all of the rights and obligations of such Master Servicer hereunder and enforce the rights under each Servicing Agreement entered into with respect to the Mortgage Loans. The Trustee, its designee or any successor master servicer appointed by the Trustee shall be deemed to have assumed all of the Master Servicer’s interest herein and therein to the same extent as if such Servicing Agreement had been assigned to the assuming party, except that the Master Servicer shall not thereby be relieved of any liability or obligations of the Master Servicer under such Servicing Agreement accruing prior to its replacement as Master Servicer, and shall be liable to the Trustee, and hereby agrees to indemnify and hold harmless the Trustee from and against all costs, damages, expenses and liabilities (including reasonable attorneys’ fees) incurred by the Trustee as a result of such liability or obligations of the Master Servicer and in connection with the Trustee’s assumption (but not its performance, except to the extent that costs or liability of the Trustee are created or increased as a result of negligent or wrongful acts or omissions of the Master Servicer prior to its replacement as Master Servicer) of the Master Servicer’s obligations, duties or responsibilities thereunder; provided that the Master Servicer shall not indemnify or hold harmless the Trustee against negligent or willful misconduct of the Trustee.

(b) The Master Servicer that has been terminated shall, upon request of the Trustee but at the expense of such Master Servicer or, at the expense of the Trust Fund to the extent provided in this Agreement, deliver to the assuming party all documents and records relating to each Servicing Agreement and the related Mortgage Loans and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of each Servicing Agreement to the assuming party.

Section 9.11. “Due–on–Sale” Clauses; Assumption Agreements.

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

(b) The Master Servicer or the related Servicer, as the case may be, shall be entitled to approve a request from a Mortgagor for the granting of an easement thereon in favor of another Person or any alteration or demolition of the related Mortgaged Property if it has determined, exercising its good faith business judgment in the same manner as it would if it were the owner of the related Mortgage Loan, that the security for, and the timely and full collectibility of, such Mortgage Loan would not be materially adversely affected thereby. Any fee collected by the Master Servicer or the related Servicer for processing such a request will be retained by the Master Servicer or such Servicer as additional servicing compensation.

Section 9.12. Release of Mortgage Files.

(a) Upon (i) becoming aware of the payment in full of any Mortgage Loan or, (ii) the receipt by the applicable Servicer of a notification that payment in full has been or will be escrowed in a manner customary for such purposes, the Master Servicer will, or will cause the applicable Servicer to, promptly notify the Trustee (or the applicable Custodian) by a certification (which certification shall include a statement to the effect that all amounts received or to be received in connection with such payment that are required to be deposited in the Collection Account maintained by the Master Servicer pursuant to Section 4.01 have been or will be so deposited) of a Servicing Officer and shall request the Trustee or the applicable Custodian, to deliver to the applicable Servicer the related Mortgage File. In lieu of sending a hard copy certification of a Servicing Officer, the Master Servicer may, or may cause the Servicer to, deliver the request for release in a mutually agreeable electronic format. To the extent that such a request, on its face, originates from a Servicing Officer, no signature shall be required. Upon receipt of such certification and request, the Trustee or the applicable Custodian, shall promptly release the related Mortgage File to the applicable Servicer and neither the Trustee nor the applicable Custodian shall have any further responsibility with regard to such Mortgage File. The Master Servicer is authorized, and each Servicer, to the extent such authority is delegated to such Servicer by the Master Servicer under the applicable Servicing Agreement, is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the Collection Account.

(b) From time to time and as appropriate for the servicing or foreclosure of, or other legal proceedings relating to, any Mortgage Loan and in accordance with Accepted Servicing Practices and the applicable Servicing Agreement, the Trustee shall execute such pleadings, request for trustee’s sale or other documents as shall be prepared and furnished to the Trustee by the Master Servicer, or by a Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Trustee or the applicable Custodian, shall, upon request of the Master Servicer, or of a Servicer, and delivery to the Trustee or the applicable Custodian, of a trust receipt signed by a Servicing Officer substantially in the form annexed hereto as Exhibit C or in the form annexed to the applicable Custodial Agreement as Exhibit C, release the related Mortgage File held in its possession or control to the Master Servicer (or the applicable Servicer). Such trust receipt shall obligate the Master Servicer or applicable Servicer to return the Mortgage File to the Trustee or applicable Custodian, as applicable, when the need therefor by the Master Servicer or applicable Servicer no longer exists unless (i) the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that herein above specified, the trust receipt shall be released by the Trustee or the applicable Custodian, as applicable, to the Master Servicer (or the applicable Servicer) or (ii) the Mortgage File has been delivered directly or through a Servicer to an attorney, or to a public trustee or other public official as required by law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially, and the Master Servicer has delivered directly or through a Servicer 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.

Section 9.13. Documents, Records and Funds in Possession of Master Servicer To Be Held for Trustee.

(a) The Master Servicer shall transmit, or cause the applicable Servicer to transmit, to the Trustee such documents and instruments coming into the possession of the Master Servicer or such Servicer from time to time as are required by the terms hereof to be delivered to the Trustee. Any funds received by the Master Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer or by a Servicer as a Subsequent Recovery, Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit of the Trustee and the Certificateholders subject to the Master Servicer’s right to retain or withdraw from the Collection Account the Master Servicing Fee and other amounts provided in this Agreement, and to the right of each Servicer to retain its Servicing Fee and other amounts as provided in the applicable Servicing Agreement. The Master Servicer shall, and shall (to the extent provided in the applicable Servicing Agreement) cause each Servicer to, provide access to information and documentation regarding the Mortgage Loans to the Trustee, its agents and accountants at any time upon reasonable request and during normal business hours, and to Certificateholders that are savings and loan associations, banks or insurance companies, the Office of Thrift Supervision, the FDIC and the supervisory agents and examiners of such Office and Corporation or examiners of any other federal or state banking or insurance regulatory authority if so required by applicable regulations of the Office of Thrift Supervision or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during normal business hours at the offices of the Master Servicer designated by it. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

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

(c) The Master Servicer hereby acknowledges that concurrently with the execution of this Agreement, the Trustee shall own or, to the extent that a court of competent jurisdiction shall deem the conveyance of the Mortgage Loans from either Seller to the Depositor not to constitute a sale, the Trustee shall have a security interest in either Mortgage Loans and in all Mortgage Files representing such Mortgage Loans and in all funds now or hereafter held by, or under the control of, a Servicer or the Master Servicer that are collected by such Servicer or the Master Servicer in connection with such Mortgage Loans, whether as scheduled installments of principal and interest or as full or partial prepayments of principal or interest or as a Subsequent Recovery, Liquidation Proceeds or Insurance Proceeds or otherwise, and in all proceeds of the foregoing and proceeds of proceeds (but excluding any fee or other amounts to which such Servicer is entitled under the applicable Servicing Agreement, or the Master Servicer or the Depositor is entitled to hereunder); and the Master Servicer agrees that so long as the Mortgage Loans are assigned to and held by the Trustee, all documents or instruments constituting part of the Mortgage Files, and such funds relating to the Mortgage Loans which come into the possession or custody of, or which are subject to the control of, the Master Servicer or any Servicer shall be held by the Master Servicer or such Servicer for and on behalf of the Trustee as the Trustee’s agent and bailee for purposes of perfecting the Trustee’s security interest therein as provided by the applicable Uniform Commercial Code or other laws.

(d) The Master Servicer agrees that it shall not, and shall not authorize any Servicer to, create, incur or subject any Mortgage Loans, or any funds that are deposited in any custodial account, Escrow Account or the Collection Account, or any funds that otherwise are or may become due or payable to the Trustee, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, nor assert by legal action or otherwise any claim or right of setoff against any Mortgage Loan or any funds collected on, or in connection with, a Mortgage Loan.

Section 9.14. Representations and Warranties of the Master Servicer.

(a) The Master Servicer hereby represents and warrants to the Depositor, the Trustee and the Trustee, for the benefit of the Certificateholders, as of the Closing Date that:

(iii) this Agreement constitutes, assuming due authorization, execution and delivery hereof by the other respective parties hereto, a legal, valid and binding obligation of the Master Servicer, enforceable against it in accordance with the terms hereof, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforcement of creditors’ rights in general, and by general equity principles (regardless of whether such enforcement is considered in a proceeding in equity or at law);

The Master Servicer shall indemnify the Depositor and the Trustee and hold them harmless against any loss, damages, penalties, fines, forfeitures, legal fees and related costs, judgments, and other costs and expenses resulting from any claim, demand, defense or assertion based on or grounded upon, or resulting from, a breach of the Master Servicer’s representations and warranties contained in Section 9.14(a). Notwithstanding anything in this Agreement to the contrary, the Master Servicer shall not be liable for special, indirect or consequential losses or damages of any kind whatsoever (including, but not limited to, lost profits). It is understood and agreed that the enforcement of the obligation of the Master Servicer set forth in this Section to indemnify the Depositor and the Trustee as provided in this Section constitutes the sole remedy (other than as set forth in Section 6.14) of the Depositor and the Trustee, respecting a breach of the foregoing representations and warranties.

Any cause of action against the Depositor relating to or arising out of the breach of the representations and warranties made in Sections 2.03(a) through (f) hereof shall accrue upon discovery of such breach by either the Depositor or the Master Servicer or notice thereof by any one of such parties to the other parties.

Section 9.16. Standard Hazard and Flood Insurance Policies.

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

Pursuant to Section 4.01, any amounts collected by the Master Servicer, or by any Servicer, under any insurance policies maintained pursuant to this Section 9.16 (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or released to the Mortgagor in accordance with the Master Servicer’s or the Servicer’s normal servicing procedures and Accepted Servicing Practices) shall be deposited into the Collection Account, subject to withdrawal pursuant to Section 4.02. Any cost incurred by the Master Servicer or any Servicer in maintaining any such insurance if the Mortgagor defaults in its obligation to do so shall be added to the amount owing under the Mortgage Loan where the terms of the Mortgage Loan so permit; provided, however, that the addition of any such cost shall not be taken into account for purposes of calculating the distributions to be made to Certificateholders and shall be recoverable by the Master Servicer or such Servicer pursuant to Section 4.02(v).

Section 9.17. Presentment of Claims and Collection of Proceeds.

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

Section 9.18. Maintenance of the Primary Mortgage Insurance Policies.

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

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

Section 9.19. Trustee To Retain Possession of Certain Insurance Policies and Documents.

The Trustee (or its custodian, if any, as directed by the Trustee), shall retain possession and custody of the originals of the Primary Mortgage Insurance Policies or certificate of insurance if applicable and any certificates of renewal as to the foregoing as may be issued from time to time as contemplated by this Agreement. Until all amounts distributable in respect of the Certificates have been distributed in full and the Master Servicer otherwise has fulfilled its obligations under this Agreement, the Trustee (or its custodian, if any, as directed by the Trustee) shall also retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions of this Agreement. The Master Servicer shall promptly deliver or cause to be delivered to the Trustee (or its custodian, if any, as directed by the Trustee), upon the execution or receipt thereof the originals of the Primary Mortgage Insurance Policies and any certificates of renewal thereof, and such other documents or instruments that constitute portions of the Mortgage File that come into the possession of the Master Servicer from time to time.

Section 9.20. Realization Upon Defaulted Mortgage Loans.

The Master Servicer shall use its reasonable best efforts to, or to cause each Servicer to, foreclose upon, repossess or otherwise comparably convert the ownership of Mortgaged Properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments, all in accordance with the applicable Servicing Agreement. Alternatively, the Master Servicer may take, or authorize any Servicer to take, other actions in respect of a defaulted Mortgage Loan, which may include (i) accepting a short sale (a payoff of the Mortgage Loan for an amount less than the total amount contractually owed in order to facilitate a sale of the Mortgaged Property by the Mortgagor) or permitting a short refinancing (a payoff of the Mortgage Loan for an amount less than the total amount contractually owed in order to facilitate refinancing transactions by the Mortgagor not involving a sale of the Mortgaged Property), (ii) arranging for a repayment plan or (iii) agreeing to a modification in accordance with Section 9.04. In connection with such foreclosure or other conversion or action, the Master Servicer shall, consistent with Section 9.18, follow such practices and procedures as it shall reasonably determine to be in the best interests of the Trust Fund and the Certificateholders and which shall be consistent with its customary practices in performing its general mortgage servicing activities; provided that the Master Servicer shall not be liable in any respect hereunder if the Master Servicer is acting in connection with any such foreclosure or other conversion or action in a manner that is consistent with the provisions of this Agreement. Neither the Master Servicer, nor any Servicer, shall be required to expend its own funds or incur other reimbursable charges in connection with any foreclosure, or attempted foreclosure which is not completed, or toward the correction of any default on a related senior mortgage loan, or towards the restoration of any property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the Mortgage Loan to the Certificateholders after reimbursement to itself for such expenses or charges and (ii) that such expenses and charges will be recoverable to it through Liquidation Proceeds or Insurance Proceeds (as provided in Section 4.02).

Section 9.21. Compensation to the Master Servicer.

The Master Servicer shall be entitled to withdraw from the Collection Account, subject to Section 5.05, the Master Servicing Fee to the extent permitted by Section 4.02(vi). Servicing compensation in the form of assumption fees, if any, late payment charges, as collected, if any, or otherwise (not including any Prepayment Penalty Amounts with respect to those Mortgage Loans for which the Seller own the servicing rights) shall be retained by the Master Servicer (or the applicable Servicer) and shall not be deposited in the Collection Account. If the Master Servicer does not retain or withdraw the Master Servicing Fee from the Collection Account as provided herein, the Master Servicer shall be entitled to direct the Trustee to pay the Master Servicing Fee to such Master Servicer by withdrawal from the Certificate Account. The Master Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor except as provided in this Agreement. Pursuant to Section 4.01(e), all income and gain realized from any investment of funds in the Collection Account shall be for the benefit of the Master Servicer as additional compensation. The provisions of this Section 9.21 are subject to the provisions of Section 6.14(b).

Section 9.22. REO Property.

(a) In the event the Trust Fund acquires ownership of any REO Property in respect of any Mortgage Loan, the deed or certificate of sale shall be issued to the Trustee, or to its nominee, on behalf of the Certificateholders. The Master Servicer shall use its reasonable best efforts to sell, or, to the extent provided in the applicable Servicing Agreement, cause the applicable Servicer to sell, any REO Property as expeditiously as possible and in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable, but in all events within the time period, and subject to the conditions set forth in Article X hereof. Pursuant to its efforts to sell such REO Property, the Master Servicer shall protect and conserve, or cause the applicable Servicer to protect and conserve, such REO Property in the manner and to such extent required by the applicable Servicing Agreement, subject to Article X hereof.

(b) The Master Servicer shall deposit or cause to be deposited all funds collected and received by it, or recovered from any Servicer, in connection with the operation of any REO Property in the Collection Account.

(c) The Master Servicer and the applicable Servicer, upon the final disposition of any REO Property, shall be entitled to reimbursement for any related unreimbursed Advances as well as any unpaid Master Servicing Fees or Servicing Fees from Liquidation Proceeds received in connection with the final disposition of such REO Property; provided, that (without limitation of any other right of reimbursement that the Master Servicer or any Servicer shall have hereunder) any such unreimbursed Advances as well as any unpaid Master Servicing Fees or Servicing Fees may be reimbursed or paid, as the case may be, prior to final disposition, out of any net rental income or other net amounts derived from such REO Property.

(d) The Liquidation Proceeds from the final disposition of the REO Property, net of any payment to the Master Servicer and the applicable Servicer as provided above, shall be deposited in the Collection Account on or prior to the Determination Date in the month following receipt thereof and be remitted by wire transfer in immediately available funds to the Trustee for deposit into the Certificate Account on the next succeeding Deposit Date.

Section 9.23. [Reserved]

Section 9.24. Reports to the Trustee.

(a) Not later than 30 days after each Distribution Date, the Master Servicer shall forward to the Trustee a statement, deemed to have been certified by a Servicing Officer, setting forth the status of the Collection Account maintained by the Master Servicer as of the close of business on the related Distribution Date, indicating that all distributions required by this Agreement to be made by the Master Servicer have been made (or if any required distribution has not been made by the Master Servicer, specifying the nature and status thereof) and showing, for the period covered by such statement, the aggregate of deposits into and withdrawals from the Collection Account maintained by the Master Servicer. Copies of such statement shall be provided by the Master Servicer to the Depositor, Attention: Contract Finance, and, upon request, any Certificateholders (or by the Trustee at the Master Servicer’s expense if the Master Servicer shall fail to provide such copies (unless (i) the Master Servicer shall have failed to provide the Trustee with such statement or (ii) the Trustee shall be unaware of the Master Servicer’s failure to provide such statement)).

(b) Not later than two Business Days following each Distribution Date, the Master Servicer shall deliver to the Person designated by the Depositor, in a format consistent with other electronic loan level reporting supplied by the Master Servicer in connection with similar transactions, “loan level” information with respect to the Mortgage Loans as of the related Determination Date (including information on any Net Prepayment Interest Shortfalls), to the extent that such information has been provided to the Master Servicer by the Servicers or by the Depositor.

(c) All information, reports and statements prepared by the Master Servicer under this Agreement shall be based on information supplied to the Master Servicer by the Servicers without independent verification thereof and the Master Servicer shall be entitled to rely on such information.

Section 9.25. Annual Officer’s Certificate as to Compliance.

(a) The Master Servicer shall deliver to the Trustee and the Rating Agencies no later than five (5) Business Days after March 15th of each year, commencing in March 2005, an Officer’s Certificate, certifying that with respect to the period ending on the immediately preceding December 31; (i) such Servicing Officer has reviewed the activities of such Master Servicer during the preceding calendar year or portion thereof and its performance under this Agreement; (ii) to the best of such Servicing Officer’s knowledge, based on such review, such Master Servicer has performed and fulfilled its duties, responsibilities and obligations under this Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof, (iii) nothing has come to the attention of such Servicing Officer to lead such Servicing Officer to believe that any Servicer has failed to perform any of its duties, responsibilities and obligations under its Servicing Agreement in all material respects throughout such year, or, if there has been a material default in the performance or fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof, (iv) the Master Servicer has received from each Servicer such Servicer’s annual certificate of compliance and a copy of such Servicer’s annual audit report, in each case to the extent required under the applicable Servicing Agreement, or, if any such certificate or report has not been received by the Master Servicer, the Master Servicer is using its best reasonable efforts to obtain such certificate or report and (v) such other additional items as may be required by applicable law or regulation.

(b) Copies of such statements shall be provided to any Certificateholder upon request, by the Master Servicer or by the Trustee at the Master Servicer’s expense if the Master Servicer failed to provide such copies (unless (i) the Master Servicer shall have failed to provide the Trustee with such statement or (ii) the Trustee shall be unaware of the Master Servicer’s failure to provide such statement).

Section 9.26. Annual Independent Accountants’ Servicing Report.

If the Master Servicer has, during the course of any fiscal year, directly serviced any of the Mortgage Loans, then the Master Servicer at its expense shall cause a nationally recognized firm of independent certified public accountants to furnish a statement to the Trustee, the Rating Agencies and the Depositor on or before the last day of February of each year, commencing on February 28, 2005, to the effect that, with respect to the most recently ended fiscal year, such firm has examined certain records and documents relating to the Master Servicer’s performance of its servicing obligations under this Agreement and pooling and servicing and trust agreements in material respects similar to this Agreement and to each other and that, on the basis of such examination conducted substantially in compliance with the audit program for mortgages serviced for FHLMC, the Uniform Single Attestation Program for Mortgage Bankers or such other attestation program as may be required by applicable law or regulation, such firm is of the opinion that the Master Servicer’s activities have been conducted in compliance with this Agreement, or that such examination has disclosed no material items of noncompliance except for (i) such exceptions as such firm believes to be immaterial, (ii) such other exceptions as are set forth in such statement and (iii) such exceptions that the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by FHLMC requires it to report. Copies of such statements shall be provided to any Certificateholder upon request by the Master Servicer, or by the Trustee at the expense of the Master Servicer if the Master Servicer shall fail to provide such copies. If such report discloses exceptions that are material, the Master Servicer shall advise the Trustee whether such exceptions have been or are susceptible of cure, and will take prompt action to do so.

Section 9.27. Merger or Consolidation.

Any Person into which the Master Servicer may be merged or consolidated, or any Person resulting from any merger, conversion, other change in form or consolidation to which the Master Servicer shall be a party, or any Person succeeding to the business of the Master Servicer, shall be the successor to the Master Servicer 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 resulting Person to the Master Servicer shall be a Person that shall be qualified and approved to service mortgage loans for FNMA or FHLMC and shall have a net worth of not less than $15,000,000.

Section 9.28. Resignation of Master Servicer.

Except as otherwise provided in Sections 9.27 and 9.29 hereof, the Master Servicer shall not resign from the obligations and duties hereby imposed on it unless it determines that the Master Servicer’s duties hereunder are no longer permissible under applicable law or are in material conflict by reason of applicable law with any other activities carried on by it and cannot be cured. Any such determination permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel that shall be Independent to such effect delivered to the Trustee. In the event such determination of ineligibility of the Master Servicer to continue in the capacity of master servicer is made by the Master Servicer or the Trustee, no such resignation shall become effective until the Trustee shall have assumed, or a successor master servicer shall have been appointed by the Trustee and until such successor shall have assumed, the Master Servicer’s responsibilities and obligations under this Agreement. Notice of such resignation shall be given promptly by the Master Servicer to the Depositor.

Section 9.29. Assignment or Delegation of Duties by the Master Servicer.

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, or delegate to or subcontract with, or authorize or appoint any other Person to perform any of the duties, covenants or obligations to be performed by the Master Servicer hereunder; provided, however, that the Master Servicer shall have the right without the prior written consent of the Trustee, the Depositor or the Rating Agencies to delegate or assign to or subcontract with or authorize or appoint an Affiliate of the Master Servicer to perform and carry out any duties, covenants or obligations to be performed and carried out by the Master Servicer hereunder. In no case, however, shall any such delegation, subcontracting or assignment to an Affiliate of the Master Servicer relieve the Master Servicer of any liability hereunder. Notice of such permitted assignment shall be given promptly by the Master Servicer to the Depositor and the Trustee. If, pursuant to any provision hereof, the duties of the Master Servicer are transferred to a successor master servicer, the entire amount of the Master Servicing Fees and other compensation payable to the Master Servicer pursuant hereto, including amounts payable to or permitted to be retained or withdrawn by the Master Servicer pursuant to Section 9.21 hereof, shall thereafter be payable to such successor master servicer.

Section 9.30. Limitation on Liability of the Master Servicer and Others.

(a) The Master Servicer undertakes to perform such duties and only such duties as are specifically set forth in this Agreement.

(b) No provision of this Agreement shall be construed to relieve the Master Servicer from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that the duties and obligations of the Master Servicer shall be determined solely by the express provisions of this Agreement, the Master Servicer 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 Master Servicer and, in absence of bad faith on the part of the Master Servicer, the Master Servicer 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 Master Servicer and conforming to the requirements of this Agreement.

(c) None of the Master Servicer, the Seller or the Depositor or any of the directors, officers, employees or agents of any of them shall be under any liability to the Trustee 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 Master Servicer, the Seller or the Depositor or any such person against any liability that would otherwise be imposed by reason of willful misfeasance, bad faith or negligence in its performance of its duties or by reason of reckless disregard for its obligations and duties under this Agreement. The Master Servicer, the Seller and the Depositor and any director, officer, employee or agent of any of them shall be entitled to indemnification by the Trust Fund and will be held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Agreement or the Certificates other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of his or its duties hereunder or by reason of reckless disregard of his or its obligations and duties hereunder. The Master Servicer, the Seller and the Depositor and any director, officer, employee or agent of any of them may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Master Servicer shall be under no obligation to appear in, prosecute or defend any legal action that is not incidental to its duties to master service the Mortgage Loans in accordance with this Agreement and that in its opinion may involve it in any expenses or liability; provided, however, that the Master Servicer may in its sole discretion undertake any such action that it may deem necessary or desirable in respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund and the Master Servicer shall be entitled to be reimbursed therefor out of the Collection Account it maintains as provided by Section 4.02.

Section 9.31. Indemnification; Third-Party Claims.

The Master Servicer agrees to indemnify the Depositor the Trustee, and hold them harmless against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liability, fees and expenses that the Depositor and the Trustee may sustain as a result of the failure of the Master Servicer to perform its duties and master service the Mortgage Loans in compliance with the terms of this Agreement. The Depositor and the Trustee shall immediately notify the Master Servicer if a claim is made by a third party with respect to this Agreement or the Mortgage Loans entitling the Depositor or the Trustee to indemnification hereunder, whereupon the Master Servicer shall assume the defense of any such claim and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against it or them in respect of such claim.

ARTICLE X

REMIC ADMINISTRATION

Section 10.01. REMIC Administration.

(a) As set forth in the Preliminary Statement hereto, the Trustee shall elect REMIC status in accordance with the REMIC Provisions with respect to each of the REMICs. The Trustee shall make such elections on Forms 1066 or other appropriate federal tax or information return for the taxable year ending on the last day of the calendar year in which the Certificates are issued. For the purposes of such elections, each of the Interests in REMIC I, other than the Class R-1 Interest, is hereby designated as a regular interest in REMIC I; each of the interests in REMIC II, other than the Class R-2 Interest, is hereby designated as a regular interest in REMIC II; and each Certificate, other than the Class R, Class E and Class P Certificates, is hereby designated as a regular interest in REMIC III. In addition, the Class R-1 Interest is hereby designated as the sole residual interest in REMIC I, the Class R-2 Interest is hereby designated as the sole residual interest in REMIC II, and the Class R Certificate evidences ownership of the Class R-1 Interest and the Class R-2 Interest, and is also hereby designated as the sole residual interest in REMIC III.

(b) The Closing Date is hereby designated as the “Startup Day” of each REMIC within the meaning of section 86OG(a)(9) of the Code. The latest possible maturity date for purposes of Treasury Regulation 1.86OG-1(a)(4) will be the Latest Possible Maturity Date.

(c) The Trustee shall pay any and all tax related expenses (not including taxes) of each REMIC, including but not limited to any professional fees or expenses related to audits or any administrative or judicial proceedings with respect to such REMIC that involve the Internal Revenue Service or state tax authorities, but only to the extent that (i) such expenses are ordinary or routine expenses, including expenses of a routine audit but not expenses of litigation (except as described in (ii)); or (ii) such expenses or liabilities (including taxes and penalties) are attributable to the negligence or willful misconduct of the Trustee in fulfilling its duties hereunder (including its duties as tax return preparer). The Trustee shall be entitled to reimbursement of expenses to the extent provided in clause (i) above from the Certificate Account, provided, however, the Trustee shall not be entitled to reimbursement for expenses incurred in connection with the preparation of tax returns and Form SS-4 as required by Section 6.20 and this Section 10.01.

(d) The Trustee shall prepare, sign and file all of each REMIC’s federal and applicable state tax and information returns as such REMIC’s direct representative. As used in the previous sentence, “applicable state tax and information returns” shall mean such returns as may be required by the laws of any state, the applicability of which to the Trust Fund shall have been confirmed to the Trustee in writing either (i) by the delivery to the Trustee of an Opinion of Counsel to such effect, or (ii) by delivery to the Trustee of a written notification to such effect by the taxing authority of such state. The expenses of preparing and filing such returns shall be borne by the Trustee. If any Disqualified Organization acquires any Ownership Interest in a Residual Certificate, then the Trustee will upon request provide to the Internal Revenue Service, and to the persons specified in Sections 860E(e)(3) and (6) of the Code, such information as required in Section 860D(a)(6)(B) of the Code needed to compute the tax imposed under Section 860E(e) of the Code on transfers of residual interests to disqualified organizations. The Trustee shall be entitled to additional compensation from such person for the cost of providing such information.

(e) The Trustee shall perform on behalf of each 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, if required by the Code, the REMIC Provisions, or other such guidance, the Trustee shall provide (i) to the Treasury or other governmental authority such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any disqualified person or organization and (ii) to the Trustee such information as is necessary for the Trustee to provide to the Certificateholders such information or reports as are required by the Code or the REMIC Provisions.

(f) The Trustee, the Master Servicer and the Holders of Certificates shall take any action within their respective control and scope of its duties or cause each REMIC to take any action necessary to create or maintain the status of such REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. None of the Trustee, the Master Servicer or the Holder of any Residual Certificate shall take any action within their respective control, cause any REMIC to take any action or fail to take (or fail to cause to be taken) any action within its control and in the scope of its duties that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of any REMIC as a REMIC or (ii) result in the imposition of a tax upon any REMIC (including but not limited to the tax on prohibited transactions as defined in Code Section 860F(a)(2) and the tax on prohibited contributions set forth on Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee and the Master Servicer have received an Opinion of Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not endanger such status or result in the imposition of such a tax. In addition, prior to taking any action with respect to any REMIC or the assets therein, or causing any REMIC to take any action, which is not expressly permitted under the terms of this Agreement any Holder of a Residual Certificate will consult with the Trustee and the Master Servicer, or their respective designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall take any such action or cause any REMIC to take any such action as to which the Trustee or the Master Servicer has advised it in writing that an Adverse REMIC Event could occur.

(g) Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on the related REMIC by federal or state governmental authorities. To the extent it has actual knowledge that such taxes were not paid by a Residual Certificateholder, the Trustee shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Residual Certificate in such REMIC or, if no such amounts are available, out of other amounts held in the Collection Account, and shall reduce amounts otherwise payable to holders of regular interests in such REMIC, as the case may be.

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

(i) No additional contributions of assets shall be made to any REMIC, except as expressly provided in this Agreement with respect to eligible substitute mortgage loans.

(j) Neither the Trustee nor the Master Servicer shall enter into any arrangement by which any REMIC will receive a fee or other compensation for services.

(k) Upon the request of any Rating Agency, the Trustee shall deliver to such Rating Agency an Officer’s Certificate stating the Trustee’s compliance with the provisions of this Section 10.01 applicable to it.

Section 10.02. Prohibited Transactions and Activities.

None of the Depositor, the Master Servicer or the Trustee shall sell, dispose of, or substitute for any of the Mortgage Loans, except in a disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund, (iii) the termination of each REMIC pursuant to Article VII of this Agreement, (iv) a substitution pursuant to Article II of this Agreement or (v) a repurchase of Mortgage Loans pursuant to Article II of this Agreement, nor acquire any assets for any REMIC, nor sell or dispose of any investments in the Certificate Account for gain, nor accept any contributions to any REMIC after the Closing Date, unless it has received an Opinion of Counsel (at the expense of the party causing such sale, disposition, or substitution) that such disposition, acquisition, substitution, or acceptance will not (a) affect adversely the status of such REMIC as a REMIC or of the Certificates other than the Residual Certificate and the Class E Certificate and Class P Certificates as the regular interests therein, (b) affect the distribution of interest or principal on the Certificates, (c) result in the encumbrance of the assets transferred or assigned to the Trust Fund (except pursuant to the provisions of this Agreement) or (d) cause such REMIC to be subject to a tax on prohibited transactions or prohibited contributions pursuant to the REMIC Provisions.

Section 10.03. Indemnification with Respect to Certain Taxes and Loss of REMIC Status.

In the event that a REMIC fails to qualify as a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a result of a prohibited transaction or prohibited contribution under the REMIC Provisions due to the negligent performance by the Trustee of its duties and obligations set forth herein, the Trustee shall indemnify the Holder of the Residual Certificate against any and all losses, claims, damages, liabilities or expenses (“Losses”) resulting from such negligence; provided, however, that the Trustee shall not be liable for any such Losses attributable to the action or inaction of the Master Servicer, the Depositor, or the Holder of such Residual Certificate, as applicable, or for any such Losses resulting from misinformation provided by the Holder of such Residual Certificate on which the Trustee has relied. The foregoing shall not be deemed to limit or restrict the rights and remedies of the Holder of such Residual Certificate now or hereafter existing at law or in equity. Notwithstanding the foregoing, however, in no event shall the Trustee have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement, (2) for any Losses other than arising out of a negligent performance by the Trustee its duties and obligations set forth herein, and (3) for any special or consequential damages to Certificateholders (in addition to payment of principal and interest on the Certificates). In addition, the Trustee shall not have any liability for the actions or failure to act of the other.

Section 10.04. REO Property.

(a) Notwithstanding any other provision of this Agreement, the Master Servicer, acting on behalf of the Trustee hereunder, shall not (except to the extent provided in the applicable Servicing Agreement) permit any Servicer to, rent, lease, or otherwise earn income on behalf of any REMIC with respect to any REO Property which might 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 REMIC of any “income from non-permitted assets” within the meaning of section 860F(a)(2) of the Code or any “net income from foreclosure property” which is subject to tax under the REMIC Provisions unless the Master Servicer has advised, or has caused the applicable Servicer to advise, the Trustee in writing to the effect that, under the REMIC Provisions, such action would not adversely affect the status of any REMIC as a REMIC and any income generated for any REMIC by the REO Property would not result in the imposition of a tax upon such REMIC.

(b) The Master Servicer shall make, or shall cause the applicable Servicer to make, reasonable efforts to sell any REO Property for its fair market value. In any event, however, the Master Servicer shall, or shall cause the applicable Servicer to, dispose of any REO Property within three years from the end of the calendar year of its acquisition by the Trust Fund unless the Trustee has received a grant of extension from the Internal Revenue Service to the effect that, under the REMIC Provisions and any relevant proposed legislation and under applicable state law, the REMIC may hold REO Property for a longer period without adversely affecting the REMIC status of such REMIC or causing the imposition of a Federal or state tax upon such REMIC. If the Trustee has received such an extension, then (a) the Trustee shall provide a copy of such extension to the Master Servicer and (b) the Trustee, or the Master Servicer, acting on its behalf hereunder, shall, or shall cause the applicable Servicer to, continue to attempt to sell the REO Property for its fair market value for such period longer than three years as such extension permits (the “Extended Period”). If the Trustee has not received such an extension and the Trustee, or the Master Servicer acting on behalf of the Trustee hereunder, or the applicable Servicer is unable to sell the REO Property within 33 months after its acquisition by the Trust Fund or if the Trustee has received such an extension, and the Trustee, or the Master Servicer acting on behalf of the Trustee hereunder, is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Master Servicer shall, or shall cause the applicable Servicer to, before the end of the three year period or the Extended Period, as applicable, (i) purchase such REO Property at a price equal to the REO Property’s fair market value or (ii) auction the REO Property to the highest bidder (which may be the Master Servicer) in an auction reasonably designed to produce a fair price prior to the expiration of the three-year period or the Extended Period, as the case may be.

Section 11.02. Entire Agreement.

This Agreement contains the entire agreement and understanding among the parties hereto with respect to the subject matter hereof, and supersedes all prior and contemporaneous agreements, understandings, inducements and conditions, express or implied, oral or written, of any nature whatsoever with respect to the subject matter hereof. The express terms hereof control and supersede any course of performance and/or usage of the trade inconsistent with any of the terms hereof.

Prior to entering into any amendment without the consent of Holders pursuant to this paragraph, the Trustee may require an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that such amendment is permitted under this paragraph. Any such amendment shall be deemed not to adversely affect in any material respect any Holder if the Trustee receives written confirmation from each Rating Agency that such amendment will not cause such Rating Agency to reduce, qualify or withdraw the then current rating assigned to the Certificates (and any Opinion of Counsel requested by the Trustee in connection with any such amendment may rely expressly on such confirmation as the basis therefor).

(b) This Agreement may also be amended from time to time by the Depositor, the Master Servicer and the Trustee with the consent of the Holders of not less than 66 2/3% of the Class Principal Amount (or Percentage Interest) of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders; provided, however, that no such amendment shall be made unless the Trustee receives an Opinion of Counsel, at the expense of the party requesting the change, that such change will not adversely affect the status of any REMIC as a REMIC or cause a tax to be imposed on any REMIC; and provided, further, that no such amendment may (i) reduce in any manner the amount of, or delay the timing of, payments received on Mortgage Loans which are required to be distributed on any Certificate, without the consent of the Holder of such Certificate or (ii) reduce the aforesaid percentages of Class Principal Amount (or Percentage Interest) of Certificates of each Class, the Holders of which are required to consent to any such amendment without the consent of the Holders of 100% of the Class Principal Amount (or Class Notional Amount) of each Class of Certificates affected thereby. For purposes of this paragraph, references to “Holder” or “Holders” shall be deemed to include, in the case of any Class of Book-Entry Certificates, the related Certificate Owners.

(c) Promptly after the execution of any such amendment, the Trustee shall furnish written notification of the substance of such amendment to each Holder, the Depositor and to the Rating Agencies.

(d) It shall not be necessary for the consent of Holders under this Section 11.03 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Holders shall be subject to such reasonable regulations as the Trustee may prescribe.

(e) Notwithstanding anything to the contrary in any Servicing Agreement, the Trustee shall not consent to any amendment of any Servicing Agreement except pursuant to the standards provided in this Section with respect to amendment of this Agreement.

(iv) If the successor servicer is not a Servicer of Mortgage Loans at the time of transfer, there must be delivered to the Trustee a letter from each Rating Agency to the effect that such transfer of servicing will not result in a qualification, withdrawal or downgrade of the then-current rating of any of the Certificates;

(v) The related Seller shall, at its cost and expense, take such steps, or cause the terminated Servicer to take such steps, as may be necessary or appropriate to effectuate and evidence the transfer of the servicing of the Mortgage Loans to such successor servicer, including, but not limited to, the following: (A) to the extent required by the terms of the Mortgage Loans and by applicable federal and state laws and regulations, the related Seller shall cause the prior Servicer to timely mail to each obligor under a Mortgage Loan any required notices or disclosures describing the transfer of servicing of the Mortgage Loans to the successor servicer; (B) prior to the effective date of such transfer of servicing, the related Seller shall cause the prior Servicer to transmit to any related insurer notification of such transfer of servicing; (C) on or prior to the effective date of such transfer of servicing, the related Seller shall cause the prior Servicer to deliver to the successor servicer all Mortgage Loan Documents and any related records or materials; (D) on or prior to the effective date of such transfer of servicing, the related Seller shall cause the prior Servicer to transfer to the successor servicer, or, if such transfer occurs after a Remittance Date but before the next succeeding Deposit Date, to the Master Servicer, all funds held by the applicable Servicer in respect of the Mortgage Loans; (E) on or prior to the effective date of such transfer of servicing, the related Seller shall cause the prior Servicer to, after the effective date of the transfer of servicing to the successor servicer, continue to forward to such successor servicer, within one Business Day of receipt, the amount of any payments or other recoveries received by the prior Servicer, and to notify the successor servicer of the source and proper application of each such payment or recovery; and (F) the related Seller shall cause the prior Servicer to, after the effective date of transfer of servicing to the successor servicer, continue to cooperate with the successor servicer to facilitate such transfer in such manner and to such extent as the successor servicer may reasonably request.

It is the intent of the parties hereto that the segregated pool of assets consisting of any collections in respect of the Class P Distributable Amount payable to Class P Certificates and the segregated pool of assets consisting of any collection in respect of the Class E Distributable Amount payable to the Class E Certificates each constitute, for federal income tax purposes, a grantor trust as described in Subpart E of Part I of Subchapter J of the Code and Treasury Regulation §301.7701-4(c)(2). The Trustee shall prepare, sign and file all of the tax returns in respect of each such grantor trust. The expenses of preparing and filing such returns shall be borne by the Trustee without any right of reimbursement therefor. The Trustee shall comply with each such requirement by filing Form 1041 or other applicable form.

We agree, on our own behalf and on behalf of any accounts for which we are acting as hereinafter stated, that if we should sell any Privately Offered Certificates within two years of the later of the date of original issuance of the Privately Offered Certificates or the last day on which such Privately Offered Certificates are owned by the Depositor or any affiliate of the Depositor (which includes the Placement Agent) we will do so only (A) to the Depositor, (B) to “qualified institutional buyers” (within the meaning of Rule 144A under the Securities Act) in accordance with Rule 144A under the Securities Act (“QIBs”), (C) pursuant to the exemption from registration provided by Rule 144 under the Securities Act, or (D) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act that is not a QIB (an “Institutional Accredited Investor”) which, prior to such transfer, delivers to the Trustee under the Trust Agreement dated as of August 1, 2004 among the Depositor, Citibank, N.A., as Trustee (the “Trustee”), and Aurora Loan Services Inc., as Master Servicer, a signed letter in the form of this letter; and we further agree, in the capacities stated above, to provide to any person purchasing any of the Privately Offered Certificates from us a notice advising such purchaser that resales of the Privately Offered Certificates are restricted as stated herein.

(2) We understand that, in connection with any proposed resale of any Privately Offered Certificates to an Institutional Accredited Investor, we will be required to furnish to the Trustee and the Depositor a certification from such transferee in the form hereof to confirm that the proposed sale is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. We further understand that the Privately Offered Certificates purchased by us will bear a legend to the foregoing effect.

(3) We are acquiring the Privately Offered Certificates for investment purposes and not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Privately Offered Certificates, and we and any account for which we are acting are each able to bear the economic risk of such investment.

(4) We are an Institutional Accredited Investor and we are acquiring the Privately Offered Certificates purchased by us for our own account or for one or more accounts (each of which is an Institutional Accredited Investor) as to each of which we exercise sole investment discretion.

(5) We have received such information as we deem necessary in order to make our investment decision.

(6) If we are acquiring ERISA-Restricted Certificates, we understand that in accordance with ERISA, the Code and the Exemption, no Plan and no person acting on behalf of such a Plan may acquire such Certificate except in accordance with Section 3.03(d) of the Trust Agreement.

Terms used in this letter which are not otherwise defined herein have the respective meanings assigned thereto in the Trust Agreement.
