Schedule A

Mortgage Loan Schedule (by Mortgage Pool)

This TRUST AGREEMENT, dated as of May 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 LASALLE BANK NATIONAL ASSOCIATION, a national banking association, as trustee (the “Trustee”).

PRELIMINARY STATEMENT

The Depositor has acquired the Mortgage Loans from 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 hereunder 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 Seller in the Mortgage Loan Sale Agreement and 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 and the Certificate Insurer. The Depositor, the Trustee 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 (i) the Reserve Fund, (ii) the Cap Agreement and (iii) the rights to receive (and the obligations to pay) Net Funds Cap Shortfalls and Unpaid Net Funds Cap Shortfalls (collectively, the “Excluded Trust Property”) be treated for federal income tax purposes as comprising three real estate mortgage investment conduits (each a “REMIC” or, in the alternative, “REMIC 1,” “REMIC 2,” and “REMIC 3”; REMIC 3 also being referred to as the “Upper Tier REMIC”). Each Certificate, other than the Class X-1 and Class R Certificates, represents ownership of a regular interest in the Upper Tier REMIC for purposes of the REMIC Provisions. The Class 1-X Certificate represents ownership of two regular interests in the Upper Tier REMIC as described in note 20 of the table below for such REMIC. In addition, each Certificate, other than the Class R, Class 1-X, and Class P Certificates, represents the right to receive payments with respect to any Net Funds Cap Shortfalls and Unpaid Net Funds Cap Shortfalls pursuant to Section 5.07. The Class R Certificate represents ownership of the sole Class of residual interest in each of REMIC 1, REMIC 2, and the Upper Tier REMIC for purposes of the REMIC Provisions.

(1)

The interest rate with respect to any Distribution Date (and the related Accrual Period) for each of these REMIC 1 Lower Tier Interests is a per annum rate equal to the weighted average of the Net Mortgage Rates of the Pool 1 Mortgage Loans as of the first day of the related Collection Period (adjusted for any prepayment received after such first day and distributed on a prior Distribution Date).

(ii)

Second, to the Class LT1-MI Interest until its principal balance equals one-half of the Component Principal Amount of the Class 1-M1 Certificate immediately after such Distribution Date;

(iii)

Third, to the Class LT1-M-2 Interest until its principal balance equals one-half of the Class Principal Amount of the Class 1-M2 Certificate immediately after such Distribution Date;

(iv)

Fourth, to the Class LT1-M3(1) Component until its principal balance equals one-half of the Class Principal Amount of the Class M3(1) Component immediately after such Distribution Date;

(v)

(2)

The Class LT2-R Interest is the sole Class of residual interest in REMIC 2. It does not have an interest rate or a principal balance.

On each Distribution Date, the Trustee shall be deemed to first pay or charge as an expense of REMIC 2 all expenses of the Trust in respect of Pool 2 for such Distribution Date.

On each Distribution Date, the Trustee shall be deemed to distribute the Interest Remittance Amount in respect of Pool 2 to the Lower Tier Interests in REMIC 2 at the rates shown above, provided, however, that interest that accrues on the Class LT2-Q Interest shall be deferred to the extent necessary to make the principal distributions under priorities (i) through (iii) as described below for such Distribution Date.

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 by the applicable Custodian (or WFHM, as servicer) on its behalf 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 (or WFHM, as servicer) 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 on behalf of the Trustee, will, 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 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 determine whether such 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 applicable 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 (or WFHM, as servicer) 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, discovering such Material Defect shall promptly identify the Mortgage Loan to which such Material Defect relates in the Interim Certification delivered to the Trustee, the Depositor and the Master Servicer. 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, the Transferor, or, if the Transferor does not do so, the Depositor, 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 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 Depositor to cure a Material Defect if, as determined by the Depositor, upon mutual agreement with the Master Servicer each 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 attached 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, the Certificate Insurer, any Custodian 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 the applicable Custodian shall perform the applicable review of the Mortgage Loans and respective certifications thereof as provided in this Section 2.02 and the Custodial Agreement.

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 provided in the Mortgage Loan Sale Agreement, if 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 the Seller under the Mortgage Loan Sale Agreement, the only right or remedy of the Trustee or any Certificateholder hereunder shall be their rights to enforce the obligations of the applicable Transferor under any applicable representation or warranty made by it. The Trustee acknowledges that, except as provided in the Mortgage Loan Sale Agreement, the Seller shall not have any other obligation or liability with respect to any breach of a representation or warranty made by it with respect to the Mortgage Loans sold by it 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) set forth in Section 2.03, (ii) of the Seller set forth in the Mortgage Loan Sale Agreement and assigned to the Depositor by the Seller under the Mortgage Loan Sale Agreement and to the Trustee by the Depositor hereunder and (iii) of each Transferor and of each Servicer assigned by the Seller 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 Certificate Insurer, the Master Servicer or the Trustee of a breach of any of such representations and warranties that materially and adversely 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 and the Certificate Insurer by the Depositor or given by any Transferor or the Seller and assigned to the Trustee, the Depositor, such Transferor or the Seller, as applicable, 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, with respect to Mortgage Loans as to which there is a breach of a representation or warranty set forth in Section 1.04(b)(v) of the Mortgage Loan Sale Agreement, at the purchase price therefor paid by the Seller under the Mortgage Loan Sale Agreement) 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 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 Certificateholders. As provided in the Mortgage Loan Sale Agreements, if any Transferor substitutes a mortgage loan for a Deleted Mortgage Loan pursuant to the related Transfer Agreement and such substitute mortgage loan is not a Qualifying Substitute Mortgage Loan, then pursuant to the terms of the Mortgage Loan Sale Agreement the Seller will, in exchange for such substitute mortgage loan, (i) pay to the Trust Fund the applicable Purchase Price for the affected Mortgage Loan or (ii) within two years of the Closing Date, substitute 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 the Seller pursuant to the Mortgage Loan Sale Agreement, or by the Transferor pursuant to the applicable Transfer Agreement, the principal portion of the funds received by the Master Servicer in respect of such repurchase of a Mortgage Loan will be considered a Principal Prepayment and the Purchase Price shall be deposited in the Collection Account or a Custodial Account, as applicable. The Trustee, upon receipt of the full amount of the Purchase Price for a Deleted Mortgage Loan, or upon receipt of notification from the Custodian that it had 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 reassign to the Depositor, the Seller or the 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 related Servicer 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 Master Servicer, the Certificate Insurer, 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 Certificate Insurer, the Master Servicer, 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 an Adverse REMIC Event.

(b)

With respect to each Qualifying Substitute Mortgage Loan to be delivered to the Trustee (or the applicable Custodian) pursuant to the terms of this Article II in exchange for a Deleted Mortgage Loan: (i) the Depositor, the Transferor or the Seller, as applicable, must deliver to the Trustee (or the applicable 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 with the cooperation of the applicable Servicer, shall (i) with respect to a Qualifying Substitute Mortgage Loan that is a Non-MERS Mortgage Loan, cause the Assignment of Mortgage to be recorded by the applicable Servicer if required pursuant to Section 2.01(c), or (ii) 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).

(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 result in an Adverse REMIC Event.

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 and the Certificate Insurer 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 shall be maintained as such throughout the term of this Agreement. The Depositor shall, 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 immediate and intermediate 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 immediate and mediate transferees, including the Trustee, in the Mortgage Loans. In connection with the transactions contemplated by this Agreement, the Seller and the Depositor authorizes its immediate or mediate 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).

ARTICLE III

THE CERTIFICATES

Section 3.01

The Certificates.

(a)

The Certificates shall be issuable in registered form only and shall be securities governed by Article 8 of the New York Uniform Commercial Code. The Book-Entry Certificates will be evidenced by one or more certificates, beneficial ownership of which will be held in the dollar denominations in Certificate Principal Amount or in the Percentage Interests, specified herein. Each Class of Class A Certificates will be issued in the minimum denominations in Certificate Principal Amount specified in the Preliminary Statement hereto and in integral multiples of $1 in excess thereof. Each Class of Class M Certificates will be issued in the minimum denominations in Certificate Principal Amount specified in the Preliminary Statement hereto and in integral multiples of $1 in excess thereof. The Class P and Class 1-X Certificates shall each be maintained in definitive, fully registered form in a minimum denomination equal to 10% of the Percentage Interest of each such Class. The Class R Certificate shall be issued as a single Certificate and maintained in definitive, fully registered form in a minimum denomination equal to 100% of the Percentage Interest of such Class. The Certificates may be issued in the form of typewritten certificates.

(b)

The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by an authorized officer. Each Certificate shall, on original issue, be authenticated by the Trustee upon the order of the Depositor upon receipt by the Trustee of the Mortgage Files described in Section 2.01. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided for herein, executed by an authorized officer of the Trustee or the Authenticating Agent, if any, by manual signature, and such certification upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. At any time and from time to time after the execution and delivery of this Agreement, the Depositor may deliver Certificates executed by the Depositor to the Trustee or the Authenticating Agent for authentication and the Trustee or the Authenticating Agent shall authenticate and deliver such Certificates as in this Agreement provided and not otherwise.

Section 3.02

Registration.

The Trustee is hereby appointed, and hereby accepts its appointment as, Certificate Registrar in respect of the Certificates and shall maintain books for the registration and for the transfer of Certificates (the “Certificate Register”). The Trustee may appoint a bank or trust company to act as Certificate Registrar. A registration book shall be maintained for the Certificates collectively. The Certificate Registrar may resign or be discharged or removed and a new successor may be appointed in accordance with the procedures and requirements set forth in Sections 6.06 and 6.07 hereof with respect to the resignation, discharge or removal of the Trustee and the appointment of a successor Trustee. The Certificate Registrar may appoint, by a written instrument delivered to the Holders and the Master Servicer, any bank or trust company to act as co registrar under such conditions as the Certificate Registrar may prescribe; provided, however, that the Certificate Registrar shall not be relieved of any of its duties or responsibilities hereunder by reason of such appointment.

Section 3.03

Transfer and Exchange of Certificates.

(a)

A Certificate (other than Book-Entry Certificates which shall be subject to Section 3.09 hereof) may be transferred by the Holder thereof only upon presentation and surrender of such Certificate at the office of the Certificate Registrar duly endorsed or accompanied by an assignment duly executed by such Holder or his duly authorized attorney in such form as shall be satisfactory to the Certificate Registrar. Upon the transfer of any Certificate in accordance with the preceding sentence, the Trustee shall execute, and the Trustee or any Authenticating Agent shall authenticate and deliver to the transferee, one or more new Certificates of the same Class and evidencing, in the aggregate, the same aggregate Certificate Principal Amount as the Certificate being transferred. No service charge shall be made to a Certificateholder for any registration of transfer of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any registration of transfer of Certificates.

(b)

A Certificate may be exchanged by the Holder thereof for any number of new Certificates of the same Class, in authorized denominations, representing in the aggregate the same Certificate Principal Amount as the Certificate surrendered, upon surrender of the Certificate to be exchanged at the office of the Certificate Registrar duly endorsed or accompanied by a written instrument of transfer duly executed by such Holder or his duly authorized attorney in such form as is satisfactory to the Certificate Registrar. Certificates delivered upon any such exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Certificates surrendered. No service charge shall be made to a Certificateholder for any exchange of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, and the Trustee or the Authenticating Agent shall authenticate, date and deliver the Certificates which the Certificateholder making the exchange is entitled to receive.

(c)

By acceptance of a Restricted Certificate or a Regulation S Global Security, whether upon original issuance or subsequent transfer, each Holder of such a Certificate acknowledges the restrictions on the transfer of such Certificate set forth thereon and agrees that it will transfer such a Certificate only as provided herein. 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 is not a U.S. person within the meaning of Regulation S and 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 of 1933, as amended (the “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 an affiliate (as defined in Rule 405 under the 0000 Xxx) of the Depositor or (y) being made to a “qualified institutional buyer” (a “QIB”) as defined in Rule 144A under the Securities Act of 1933, as amended (the “Act”) 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, or to any Person all of the equity owners in which are such accredited investors, 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 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, the Depositor or any NIM Insurer 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, counsel reasonably satisfactory to the Trustee has rendered an opinion 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, the NIMS Insurer 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 a 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 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, the Master Servicer 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 a 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, or an 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 or Certificate Owner of a Restricted Certificate, ERISA-Restricted Certificate or Residual Certificate, or an interest therein, by such Holder’s or Owner’s acceptance thereof, shall be deemed for all purposes to have consented to the provisions of this section.

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 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.

(a)

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. 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):

(i)

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

(ii)

the Depositor, the Master Servicer, the Paying Agent, the 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;

(iii)

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

(iv)

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 (or Class Notional 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.

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 “Collection Account, 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 2004-11XS” or its nominee. 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 15 days and transfer all funds and investment property 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. The Master Servicer shall take such actions as are necessary to cause the depository institution holding the Collection Account to hold such account in the name of the Master Servicer under this Agreement. On each Master Servicer Remittance Date, the entire amount on deposit in the Collection Account (subject to permitted withdrawals set forth in Section 4.02), other than amounts not included in the Total Distribution Amount for such Distribution Date, 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 (but 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 received with respect to the Mortgage Loans representing Scheduled Payments on the Mortgage Loans due after the Cut-off Date and unscheduled payments received on or after the Cut-off Date and on or before the Closing Date. Thereafter, the Master Servicer shall deposit or cause to be deposited in the Collection Account one Business Day following receipt thereof, 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 Premiums, on the Mortgage Loans;

(ii)

all payments on account of interest on the Mortgage Loans, in all cases, net of the 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 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 (x) any unpaid 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) and (y) any amounts reimbursable to a Servicer with respect to such Mortgage Loan under the applicable Servicing Agreement and retained by such Servicer;

(iv)

all Insurance Proceeds;

(v)

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

(vi)

all amounts paid by any Servicer with respect to Prepayment Interest Shortfalls; and

(vii)

the Purchase Price of any Mortgage Loan repurchased by the Depositor, the Seller, the Master Servicer or any other Person, the purchase price of any Mortgage Loan sold pursuant to an Auction Call in accordance with Section 7.01(c), and any Substitution Amount 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 one Business Day prior to the Master Servicer Remittance Date (except that if such Eligible Investment is an obligation of the Trustee, then such Eligible Investment shall mature not later than such applicable Master Servicer Remittance Date) 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 the Holders of Structured Asset Securities Corporation Mortgage Pass-Through Certificates, Series 2004-11XS. All income and gain realized from any Eligible Investment shall be for the benefit of the Master Servicer and shall be subject to its withdrawal or 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 such 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, assumption fees, prepayment penalties with respect to mortgages for which the Seller does not own the servicing rights, and other incidental fees and charges relating to the Mortgage Loans (other than Prepayment Premiums) 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 such 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 or Servicing Advances made by it or by such Servicer pursuant to Section 5.04 or the applicable Servicing Agreement; such right to reimbursement pursuant to this sub-clause (i) is limited to amounts received on or in respect of a particular Mortgage Loan (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) of payments of principal or interest respecting which any such Advance was made, 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, following a final liquidation of a Mortgage Loan (except as otherwise provided in the related Servicing Agreement) for any previously unreimbursed Advances or Servicing Advances made by it or by such Servicer (A) 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 Advance or Servicing Advance was made or from Liquidation Proceeds or Insurance Proceeds with respect to such Mortgage Loan and/or (B) to the extent that such unreimbursed Advances or Servicing Advances exceed the related Liquidation Proceeds or Insurance Proceeds, it being understood, in the case of each 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(c) 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 Rate 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)

[Reserved];

(v)

to reimburse itself or any Servicer for expenses incurred by and recoverable by or reimbursable to it or any Servicer pursuant to Sections 9.04, 9.05, 9.06 9.07(a), 9.16, 9.30 or 11.15 or pursuant to the related Servicing Agreement;

(vi)

to pay to the Depositor, the Seller or any Transferor, as applicable, with respect to each Mortgage Loan or REO Property acquired in respect thereof that has been purchased pursuant to this Agreement, all amounts received thereon and not distributed on the date on which the related repurchase was effected, and to pay to the applicable Person any Advances and Servicing Advances to the extent specified in the definition of Purchase Price;

(vii)

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

(viii)

to make payments to the Trustee on each Master Servicer Remittance Date for deposit into the Certificate Account in the amount provided in Section 4.04;

(ix)

to make payment to itself and others pursuant to any other 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.

In the event that the Master Servicer fails on any Master Servicer Remittance Date to remit to the Trustee any amounts required to be so remitted to the Trustee pursuant to sub-clause (viii) by 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 Master Servicer Remittance Date to but not including the related Distribution Date. The Master Servicer shall only be required to pay the Trustee interest for the actual number of days such amounts are not timely remitted (e.g., one day’s interest, if such amounts are remitted one day after the Master Servicer Remittance Date).

In connection with withdrawals pursuant to sub-clauses (i), (iii), and (vi) above, the Master Servicer’s, any Servicer’s or such other Person’s entitlement thereto is limited to collections or other recoveries on the related Mortgage Loan. 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 such sub-clause (i), (iii) and (vi).

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 to 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.

Section 5.04

Advances by Master Servicer, Servicers and Trustee.

(a)

Subject to Section 9.07, Advances shall be made in respect of each Determination Date as provided herein. If, on any Determination Date, any Servicer determines that any Scheduled Payments due during the related Collection Period (other than Balloon Payments) have not been received, such Servicer shall advance such amount to the extent provided in the applicable Servicing Agreement. If any Servicer fails to remit Advances required to be made under the applicable Servicing Agreement, the Master Servicer shall itself make, or shall cause the successor Servicer to make, such Advance on the Master Servicer Remittance Date immediately following such Determination Date; provided, however, that required Advances remitted by the Servicer or the Master Servicer may be reduced by 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 Master Servicer Remittance 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 Master Servicer Remittance Date to the extent that funds in the Certificate Account on such Master Servicer Remittance Date shall be less than payments to Certificateholders required to be made on the related Distribution Date. 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. Notwithstanding anything to the contrary herein, in the event the Master Servicer determines in its reasonable judgment that an Advance is non-recoverable, the Master Servicer shall be under no obligation to make such Advance. 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.

(b)

In the event that the Master Servicer or Servicer fails for any reason to make an Advance required to be made pursuant to this Section 5.04 on or before the Master Servicer Remittance Date, the Trustee, 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 or the Servicers that would have been deposited in such Certificate Account over (b) the amount of any Advance made by the Master Servicer or any Servicer 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

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 Interest Remittance Amount.

Section 5.06

The Certificate Insurance Policy.

(a)

If, on the second Business Day before any Distribution Date, the Trustee determines that an Insured Payment is required to be made by the Certificate Insurer on such Distribution Date, the Trustee shall determine the amount of any such Insured Payment and shall give written notice to the Certificate Insurer by completing a Notice of Nonpayment in the form of Exhibit A to the Certificate Insurance Policy and submitting such Notice of Nonpayment by 12:00 noon, New York City time on such second Business Day as a claim for an Insured Payment. The Trustee’s responsibility for delivering a Notice of Nonpayment to the Certificate Insurer, as provided in the preceding sentence, is limited to the availability, timeliness and accuracy of the information provided to it by the Master Servicer.

In the event the Trustee receives a certified copy of an order of the appropriate court that any scheduled payment of principal or interest on a Class 1-A3A, Class 1-A5B or Class 1-A6 Certificate has been voided in whole or in part as a preference payment under applicable bankruptcy law, the Trustee shall promptly notify the Certificate Insurer in writing, as appropriate, and the fiscal agent, if any, and the Trustee shall make a claim on the Certificate Insurance Policy in accordance with the provisions thereof to obtain payment by the Certificate Insurer of such voided scheduled payment. In addition, the Trustee shall mail notice to all Holders of the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable, so affected that, in the event that any such Holder’s scheduled payment is so recovered, such Holder will be entitled to payment pursuant to the terms of the Certificate Insurance Policy, a copy of which shall be made available to such Holders by the Trustee. The Trustee shall furnish to the Certificate Insurer and the appropriate fiscal agent, if any, its records listing the payments on the affected Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, if any, that have been made by the Trustee and subsequently recovered from the affected Holders, and the dates on which such payments were made by the Trustee.

(b)

At the time of the execution hereof, and for the purposes hereof, the Trustee shall establish the Policy Payments Account over which the Trustee shall have exclusive control and sole right of withdrawal. The Policy Payments Account shall be an Eligible Account. The Trustee shall deposit any amount paid under the Certificate Insurance Policy into the Policy Payments Account and distribute such amount only for the purposes of making payments to Holders of the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable, in respect of the Guaranteed Distributions (or other amounts payable pursuant to the second paragraph of subsection (a) above on any such Class of Certificates by the Certificate Insurer pursuant to the Certificate Insurance Policy) for which the related claim was made under the Certificate Insurance Policy. Such amounts shall be allocated by the Trustee to Holders of Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates entitled to such payments in the same manner as principal and interest distributions are to be allocated with respect to such Certificates pursuant to Section 5.02. It shall not be necessary for such payments to be made by checks or wire transfers separate from the checks or wire transfers used to make regular payments hereunder with funds withdrawn from the Certificate Account. However, any payments made on the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates from funds in the Policy Payments Account shall be noted as provided in subsection (e) below. Funds held in the Policy Payments Account shall not be invested by the Trustee.

(c)

Any funds received from the Certificate Insurer for deposit into the Policy Payments Account pursuant to the Certificate Insurance Policy in respect of a Distribution Date or otherwise as a result of any claim under such Certificate Insurance Policy shall be applied by the Trustee directly to the payment in full (i) of the Insured Payments due on such Distribution Date on the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable, or (ii) of other amounts to which payments under the Certificate Insurance Policy are to be applied. Funds received by the Trustee as a result of any claim under the Certificate Insurance Policy shall be used solely for payment to the Holders of the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable, and may not be applied for any other purpose, including, without limitation, satisfaction of any costs, expenses or liabilities of the Trustee or the Trust Fund. Any funds remaining in the Policy Payments Account on the first Business Day after each Distribution Date (other than the final Distribution Date to the extent of funds remaining in the Policy Payments Account required to be paid to Holders of the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable) shall be remitted promptly to the Certificate Insurer pursuant to the written instruction of the Certificate Insurer.

(d)

The Trustee shall keep complete and accurate records in respect of (i) all funds remitted to the Trustee by the Certificate Insurer and deposited into the Policy Payments Account and (ii) the allocation of such funds to (A) payments of interest on and principal in respect of any Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable (B) Applied Loss Amounts allocated to the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable and (C) payments in respect of Preference Amounts. The Certificate Insurer shall have the right to inspect such records at reasonable times during normal business hours upon three Business Days’ prior notice to the Trustee. Any Insured Payments disbursed by the Trustee from proceeds of the Certificate Insurance Policy shall be considered payment by the Certificate Insurer and not by the Trust Fund with respect to the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable, and the Certificate Insurer will be entitled to receive the related Reimbursement Amount pursuant to Section 5.02(b)(iii).

(e)

The Trustee acknowledges, and each Holder of a Class 1-A3A, Class 1-A5B or Class 1-A6 Certificate by their acceptance of such Certificates agree, that, without the need for any further action on the part of the Certificate Insurer or the Trustee, to the extent the Certificate Insurer pays Insured Payments, directly or indirectly, on account of principal of or interest on any such Class of Certificates, the Certificate Insurer will be fully subrogated to the rights of the Holders of such Class to receive the related Reimbursement Amount pursuant to Section 5.02(b)(iii) and the Certificate Insurer shall also have the rights conferred to the Certificate Insurer pursuant to Sections 4.06 and 5.02 of the Insurance Agreement, as if fully set forth herein. The Class 1-A3A, Class 1-A5B or Class 1-A6 Certificateholders, by acceptance of their respective Classes of Certificates assign their rights as Holders of such Class of Certificates to the extent of the Certificate Insurer’s interest with respect to amounts paid under the Certificate Insurance Policy. Each of the Depositor and Trustee agrees to such subrogation and, further agrees to execute such instruments and to take such actions as, in the sole judgment of the Certificate Insurer are necessary to evidence such subrogation and, subject to the priority of payment provisions of this Agreement, to perfect the rights of the Certificate Insurer to receive any moneys paid or payable in respect of the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable, under this Agreement or otherwise. Anything herein to the contrary notwithstanding, solely for purposes of determining the Certificate Insurer’s rights as subrogee for payments distributable pursuant to Section 5.02, any payment with respect to distributions to the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable, that is made with funds received pursuant to the terms of the Certificate Insurance Policy shall not be considered payment of such Class of Certificates from the Trust Fund and shall not result in the distribution or the provision for the distribution in reduction of the Class Principal Amount of such Class of Certificates or Current Interest thereon, within the meaning of Article V.

(f)

The Trustee shall promptly notify the Certificate Insurer of either of the following as to which a Responsible Officer has actual knowledge: (A) the commencement of any proceeding by or against the Depositor commenced under the Bankruptcy Code or any other applicable bankruptcy, insolvency, receivership, rehabilitation or similar law (an “Insolvency Proceeding”) and (B) the making of any claim in connection with any Insolvency Proceeding seeking the avoidance as a preferential transfer (a “Preference Claim”) of any distribution made with respect to the Class 1-A3A, Class 1-A5B or Class 1-A6 Certificates, as applicable. Each Holder of a Class 1-A3A, Class 1-A5B or Class 1-A6 Certificate, by its purchase of its respective Class of Certificate, and the Trustee hereby agree that the Certificate Insurer (so long as no Certificate Insurer Default exists) may at any time during the continuation of any proceeding relating to a Preference Claim direct all matters relating to such Preference Claim, including, without limitation, (i) the direction of any appeal of any order relating to any Preference Claim and (ii) the posting of any surety, supersedeas or performance bond pending any such appeal. In addition and without limitation of the foregoing, the Certificate Insurer shall be subrogated to the rights of the Trustee and each Holder of a Class 1-A3A, Class 1-A5B or Class 1-A6 Certificate in the conduct of any Preference Claim, including, without limitation, all rights of any party to an adversary proceeding action with respect to any court order issued in connection with any such Preference Claim.

(g)

The Trustee shall surrender the Certificate Insurance Policy to the Certificate Insurer for cancellation upon the termination of the Trust Fund pursuant to Article VII hereof.

The Reserve Fund shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other moneys, including, without limitation, other moneys of the Trustee held pursuant to this Agreement.

(b)

On each Distribution Date on which there is a payment received under the Cap Agreement that is based on a notional amount in excess of the aggregate Class Principal Amount of the Class 1-A1A and Class 1-A1B Certificates (such amount, the “Class 1-X Excess Cap Amount”), the Trustee shall not treat such payments as amounts on deposit in the Reserve Fund for purposes of determining the Pool 1 Required Reserve Fund Amount for any Distribution Date. Any such Class 1-X Excess Cap Amount shall not be an asset of the Trust Fund and, instead, shall be paid into and distributed out of a separate trust created by this Agreement for the benefit of the Class 1-X Certificateholders, and the Trustee shall distribute such amount to the Class 1-X Certificateholders pursuant to Section 5.02(f)(iii). On each Distribution Date the Trustee shall distribute in the order of priority and to the extent specified in Section 5.02(f)(iii) of this Agreement the sum of (without duplication) (a) any payments made by the Cap Provider to the Trust Fund for such Distribution Date with respect to the Cap Agreement and (b) any amounts then on deposit in the Reserve Fund, including any earnings thereon, in respect of the Cap Agreement. On any Distribution Date, any amounts that the Trustee is not required to distribute from the Reserve Fund pursuant to Section 5.02(f)(iii) of this Agreement shall remain on deposit in the Reserve Fund.

(c)

Funds in the Reserve Fund shall be invested in Eligible Investments. The Class 1-X Certificates shall evidence ownership of the Reserve Fund for federal income tax purposes and LBH on behalf of the Holders thereof shall direct the Trustee, in writing, as to investment of amounts on deposit therein. LBH shall be liable for any losses incurred on such investments. LBH hereby directs the Trustee to invest funds on deposit in the Reserve Fund in such investment as is hereafter specified to the Trustee by LBH from time to time.

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 or any Servicer to the Trustee pursuant to this Agreement, and 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. Notwithstanding anything in this Agreement to the contrary, the Trustee shall not be liable for special, indirect or consequential losses or damages of any kind whatsoever (including, but not limited to, lost profits). No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that:

(i)

The Trustee shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction or with the consent of Holders of Certificates as provided in Section 6.18 hereof;

(ii)

For all purposes under this Agreement, the Trustee shall not be deemed to have notice of any Event of Default (other than resulting from a failure by the Master Servicer (i) to remit funds (or to make Advances) or (ii) to furnish information to the Trustee when required to do so) unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office, and such notice references the Holders of the Certificates and this Agreement;

(iii)

No provision of this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and none of the provisions contained in this Agreement shall in any event require the Trustee to perform, or be responsible for the manner of performance of, any of the obligations of the Depositor or the Master Servicer under this Agreement or the Certificate Insurer under the Certificate Insurance Policy; and

(d)

The Trustee shall have no duty hereunder with respect to any complaint, claim, demand, notice or other document it may receive or which may be alleged to have been delivered to or served upon it by the parties as a consequence of the assignment of any Mortgage Loan hereunder; provided, however, that the Trustee shall promptly remit to the Master Servicer upon receipt any such complaint, claim, demand, notice or other document (i) which is delivered to the Corporate Trust Office of the Trustee, (ii) of which a Responsible Officer has actual knowledge, and (iii) which contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property.

(e)

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

(f)

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

(g)

The Trustee shall not be held liable by reason of any insufficiency in the Collection Account or the Reserve Fund resulting from any investment loss on any Eligible Investment included therein (except to the extent that the Trustee is the obligor and has defaulted thereon).

Except as otherwise provided herein, the Trustee shall not have any duty (A) to see to any recording, filing, or depositing of this Agreement or any agreement referred to herein or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of any such recording or filing or depositing or to any rerecording, refiling or redepositing of any thereof, (B) to see to any insurance, (C) to see to the payment or discharge of any tax, assessment, or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Trust Fund other than from funds available in the Collection Account or the Certificate Account, or (D) to confirm or verify the contents of any reports or certificates of the Master Servicer, any Servicer or the Depositor delivered to the Trustee pursuant to this Agreement believed by the Trustee to be genuine and to have been signed or presented by the proper party or parties.

(i)

The Trustee shall not be liable in its individual capacity for an error of judgment made in good faith by a Responsible Officer or other officers of the Trustee unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts.

(j)

Notwithstanding anything in this Agreement to the contrary, the Trustee shall not be liable for special, indirect or consequential losses or damages of any kind whatsoever (including, but not limited to, lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

The reasonable expense thereof shall be paid by the party requesting such investigation and if not reimbursed by the requesting party shall be reimbursed to the Trustee by the Trust Fund;

The separate Trustees, co-trustees, or custodians so appointed shall be trustees or custodians for the benefit of all the Certificateholders and shall have such powers, rights and remedies as shall be specified in the instrument of appointment; provided, however, that no such appointment shall, or shall be deemed to, constitute the appointee an agent of the Trustee.

all other rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee, co-trustee, or custodian jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations, including the holding of title to the Trust Fund or any portion thereof in any such jurisdiction, shall be exercised and performed by such separate trustee, co-trustee, or custodian;

(iii)

no trustee or custodian hereunder shall be personally liable by reason of any act or omission of any other trustee or custodian hereunder; and

(iv)

the Trustee or the Certificateholders evidencing more than 50% of the Aggregate Voting Interests of the Certificates may at any time accept the resignation of or remove any separate trustee, co-trustee or custodian, so appointed by it or them, if such resignation or removal does not violate the other terms of this Agreement.

(c)

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

Any Authenticating Agent may at any time resign by giving at least 30 days’ advance written notice of resignation to the Trustee and the Depositor. The Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and the Depositor. Upon receiving a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.10, the Trustee may appoint a successor Authenticating Agent, shall give written notice of such appointment to the Depositor and shall mail notice of such appointment to all Holders of Certificates. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named as Authenticating Agent.

Indemnification of Trustee.

The Trustee and its respective directors, officers, employees and agents shall be entitled to indemnification from the Trust Fund for any loss, liability or expense incurred in connection with any legal proceeding or incurred without negligence or willful misconduct on their part, arising out of, or in connection with, the acceptance or administration of the trusts created hereunder or in connection with the performance of their duties hereunder or under the Certificate Insurance Policy, the Cap Agreement, the Mortgage Loan Sale Agreement, any Transfer Agreement, any Servicing Agreement or any Custodial Agreement, including any applicable fees and expenses payable pursuant to Section 6.12 and the costs and expenses of defending themselves against any claim in connection with the exercise or performance of any of their powers or duties hereunder, provided that:

(i)

with respect to any such claim, the Trustee shall have given the Depositor, the Master Servicer and the Holders written notice thereof promptly after the Trustee shall have knowledge thereof, provided that failure of the Trustee to provide such written notice shall not relieve the Trust Fund of the obligation to indemnify the Trustee under this Section 6.11;

(ii)

while maintaining control over its own defense, the Trustee shall cooperate and consult fully with the Depositor in preparing such defense; and

(iii)

notwithstanding anything to the contrary in this Section 6.11, the Trust Fund shall not be liable for settlement of any such claim by the Trustee entered into without the prior consent of the Depositor, which consent shall not be unreasonably withheld.

A sale or pledge of any of the rights of the Master Servicer hereunder or an assignment of this Agreement by the Master Servicer or a delegation of the rights or duties of the Master Servicer hereunder shall have occurred in any manner not otherwise permitted hereunder and without the prior written consent of the Trustee and Certificateholders holding more than 50% of the Aggregate Voting Interests of the Certificates; or

(ix)

The Master Servicer has notice or actual knowledge that any Servicer at any time is not either an FNMA- or FHLMC- approved Seller/Servicer, and the Master Servicer has not terminated the rights and obligations of such Servicer under the applicable Servicing Agreement and replaced such Servicer with an FNMA- or FHLMC-approved servicer within 60 days of the date the Master Servicer receives such notice or actual knowledge; or

(x)

Any failure of the Master Servicer to remit to the Trustee any payment required to be made to the Trustee for the benefit of Certificateholders under the terms of this Agreement, including any Advance, on any Master Servicer Remittance Date, which failure continues unremedied for a period of one Business Day after the date upon which written notice of such failure shall have been given to the Master Servicer by the Trustee.

If an Event of Default described in clauses (i) through (ix) of this Section 6.14 shall occur, then, in each and every case, subject to applicable law, so long as any such Event of Default shall not have been remedied within any period of time prescribed by this Section, the Trustee, by notice in writing to the Master Servicer may, and shall, if so directed by Certificateholders evidencing more than 50% of the Class Principal Amount of each Class of Certificates, terminate all of the rights and obligations of the Master Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof. If an Event of Default described in clause (x) of this Section 6.14 shall occur, then, in each and every case, subject to applicable law, so long as such Event of Default shall not have been remedied within the time period prescribed by clause (x) of this Section 6.14, the Trustee, by notice in writing to the Master Servicer, shall promptly terminate all the rights and obligations of the Master Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof. On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer, and only in its capacity as Master Servicer under this Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee and pursuant to and under the terms of this Agreement the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the defaulting Master Servicer as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents or otherwise. The defaulting Master Servicer agrees to cooperate with the Trustee in effecting the termination of the defaulting Master Servicer’s responsibilities and rights hereunder as Master Servicer including, without limitation, notifying Servicers of the assignment of the master servicing function and providing the Trustee or its designee all documents and records in electronic or other form reasonably requested by it to enable the Trustee or its designee to assume the defaulting Master Servicer’s functions hereunder and the transfer to the Trustee for administration by it of all amounts which shall at the time be or should have been deposited by the defaulting Master Servicer in the Collection Account maintained by such defaulting Master Servicer and any other account or fund maintained with respect to the Certificates or thereafter received with respect to the Mortgage Loans. The Master Servicer being terminated shall bear all costs of a master servicing transfer, including but not limited to those of the Trustee or Trustee reasonably allocable to specific employees and overhead, legal fees and expenses, accounting and financial consulting fees and expenses, and costs of amending the Agreement, if necessary.

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 servicing from the predecessor Master Servicer, including, without limitation, any costs or expenses associated with the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data as may be required by the Trustee to correct any errors or insufficiencies in the servicing data or otherwise to enable the Trustee to 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 therefore, 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(b); provided that the terminated Master Servicer shall reimburse the Trust Fund for any such expense incurred by the Trust Fund; and provided, further, that the Trustee shall decide whether and to what extent it is in the best interest of the Certificateholders to pursue any remedy against any party obligated to make such reimbursement.

Notwithstanding the termination of its activities as Master Servicer, each terminated Master Servicer shall continue to be entitled to reimbursement to the extent provided in Section 4.02(i), (ii), (iii), (v), (vii) and (ix) to the extent such reimbursement relates to the period prior to such Master Servicer’s termination.

If any Event of Default shall occur of which a Responsible Officer of the Trustee has actual knowledge, the Trustee shall promptly notify the Certificate Insurer and each Rating Agency of the nature and extent of such Event of Default. The Trustee shall immediately give written notice to the Master Servicer upon the Master Servicer’s failure to remit funds on the Master Servicer Remittance Date.

(b)

Within 90 days of the time the Master Servicer receives a notice of termination from the Trustee pursuant to Section 6.14(a) or the Trustee receives the resignation of the Master Servicer evidenced by an Opinion of Counsel pursuant to Section 9.28, the Trustee unless another master servicer shall have been appointed, shall be the successor in all respects to the Master Servicer in its capacity as such under this Agreement and the transactions set forth or provided for herein and shall have all the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto and arising thereafter placed on the Master Servicer hereunder, including the obligation to make Advances; provided, however, that any failure to perform such duties or responsibilities caused by the Master Servicer’s failure to provide information required by this Agreement shall not be considered a default by the Trustee hereunder. In addition, the Trustee shall have no responsibility for any act or omission of the Master Servicer prior to the issuance of any notice of termination and within a period of time not to exceed 90 days after the issuance of notice of termination pursuant to Section 6.14(a) or Section 9.28 or for any breach of representation or warranty by such predecessor Master Servicer. The Trustee shall have no liability relating to the representations and warranties of the Master Servicer set forth in Section 9.14. In the Trustee’s capacity as such successor, the Trustee shall have the same limitations on liability herein granted to the Master Servicer. 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, petition a court of competent jurisdiction to appoint, or appoint on its own behalf 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, 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.

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 and the Certificate Insurer (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.

More than 50% 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 Certificate Insurer and 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 Percentage Interest) of each Class of Certificates affected thereby 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 for which it is not indemnified to its satisfaction 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 the Certificateholders.

(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 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 earliest 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, (ii) the latest to occur of the sale of the property held by the Trust Fund in accordance with (x) Section 7.01(b), (y) Section 7.01(c) or (z) Section 7.01(d) and (iii) the Latest Possible Maturity Date; 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. 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 as evidenced by an Opinion of Counsel provided to the Trustee and the Certificate Insurer at the expense of the Trust Fund.

(b)

On any Distribution Date occurring on or after the Pool 1 Initial Optional Purchase Date, the Master Servicer, with the prior written consent of the Seller (which consent shall not be unreasonably withheld) and, subject to Section 11.16(c), with the consent of the Certificate Insurer, has the option to cause the Trust Fund to sell all of its property in Pool 1 upon written direction to the Trustee (delivered no later than 30 days prior to the anticipated sale date). The Master Servicer has agreed not to exercise such option so long as any NIM Securities remain outstanding. Upon exercise of such option, the property of the Pool 1 shall be sold to the Master Servicer at a price (the “Pool 1 Termination Price”) equal to the sum of (i) 100% of the unpaid principal balance of each Pool 1 Mortgage Loan on the day of such purchase plus interest accrued thereon at the applicable Mortgage Rate to the Due Date in the Due Period immediately preceding the related Distribution Date, (ii) the amount of any unreimbursed Servicing Advances and amounts owed to the Trustee relating to Pool 1 hereunder, (iii) the fair market value of any REO Property and any other property held by REMIC 1, such fair market value to be determined by an appraiser or appraisers mutually agreed upon by the Master Servicer and the Trustee, and (iv) any Reimbursement Amounts due to the Certificate Insurer. The Master Servicer, each Servicer (or the Trustee, if applicable) shall be reimbursed from the Pool 1 Termination Price for any Mortgage Loan in Pool 1 or related REO Property for any Advances made or other amounts advanced with respect to the Mortgage Loans in Pool 1 that are reimbursable to the Master Servicer or the Trustee under this Agreement or the related Servicing Agreement (or to the Trustee hereunder), together with any accrued and unpaid compensation due to the Master Servicer hereunder or the Servicers thereunder, and the Trustee shall be entitled to be reimbursed from the Pool 1 Termination Price for any related amounts owed to the Trustee under Section 6.11 and Section 6.12 hereof.

(c)

On the later of (a) the earlier of (x) the first Distribution Date on which the Principal Balance of Pool 2, after giving effect to distributions on that date, is less than or equal to 20% of the Pool 2 Cut-off Date Balance and (y) the Distribution Date in April 2009 and (b) the June 2006 Distribution Date, the Trustee shall engage a financial advisor to begin to solicit bids in a commercially reasonable manner for the purchase of the Pool 2 Mortgage Loans and all other property of Pool 2 on a non-recourse basis with no representations or warranties of any nature whatsoever by the Trustee (such event, the “Pool 2 Auction Call”). The Distribution Date following the later of (a) or (b) above is the “Pool 2 Initial Auction Call Date.” To effectuate such sale, the Trustee (or an agent thereof) shall make reasonable efforts to sell all of the property of Pool 2 for its fair market value in a commercially reasonable manner and on commercially reasonable terms, which shall include the good faith solicitation of competitive bids to prospective purchasers that are considered at the time by the financial advisor to be competitive participants in the applicable mortgage market. The Trustee may consult any financial advisor of its choice in order to identify potential bidders. The Trustee (or an agent thereof) shall sell all of the property of Pool 2 to the highest bidder; provided, that (i) the sale price shall not be less than the Minimum Bid Price, (ii) the Trustee (or its agent) shall have received bids from no fewer than three prospective purchasers (other than the Class R Certificateholder and any Affiliate of the Class R Certificateholder) and (iii) such funds shall be deposited with the Trustee prior to the Distribution Date following the month in which such bid is received. The Trustee, its agent and any financial advisor shall be entitled to reimbursement for all costs and expenses incurred by it under this Section 7.01(c) from assets of the Trust Fund relating to Pool 2 only.

If after following the procedures set forth in the immediately preceding paragraph the Trustee (or its agent) is unable to identify a prospective purchaser of the property of Pool 2 that is willing to pay the Minimum Bid Price therefor, the above-specified process shall be repeated at three-month intervals until the earlier of (i) all of the property of Pool 2 has been sold or (ii) the Master Servicer purchased all of the property of Pool 2 pursuant to subsection (d) below.

(d)

On any Distribution Date occurring (a) after the Distribution Date in June 2006 and (b) on or after the Pool 2 Initial Optional Purchase Date, the Master Servicer, with the prior written consent of the Seller (which consent shall not be unreasonably withheld) has the option to cause the Trust Fund to sell all of its property in Pool 2 upon written direction to the Trustee (delivered no later than 30 days prior to the anticipated sale date). The Master Servicer has agreed not to exercise such option so long as any NIM Securities remain outstanding. Upon exercise of such option, the property of Pool 2 shall be sold to the Master Servicer at a price (the “Pool 2 Termination Price”) equal to the sum of (i) 100% of the unpaid principal balance of each Mortgage Loan in Pool 2 on the day of such purchase plus interest accrued thereon at the applicable Mortgage Rate to the Due Date in the Due Period immediately preceding the related Distribution Date to the date of such repurchase, (ii) the amount of any unreimbursed Servicing Advances and amounts owed to the Trustee hereunder and relating to Pool 2, (iii) the fair market value of any REO Property and any other property held by REMIC 2, such fair market value to be determined by an appraiser or appraisers mutually agreed upon by the Master Servicer and the Trustee.

(e)

On the latest to occur of (i) a sale of the assets held in Pool 1 pursuant to 7.01(b) above or (ii) a sale of the assets held in Pool 2 pursuant to 7.01(c) or 7.01(d) above, the Trust Fund will adopt a plan of complete liquidation pursuant to Section 7.03(a)(i) hereof to sell all of its property upon written direction to the Trustee (delivered no later than 30 days prior to the anticipated sale date).

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 the Class 1-A, Class 1-M1, Class 1-M2, Class M3, Class P and Class 1-X Certificateholders in the case of a termination pursuant to Section 7.01(b) or 7.01(e) or the Class 2-A1, Class 2-A2, Class 2-M1, Class 2-M2, Class M3, Class P and Class 1-X Certificateholders in the case of a termination pursuant to Section 7.01(c), 7.01(d) or 7.01(e), as applicable, mailed upon (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 related Mortgage Pool pursuant to Section 7.01 (b) or (d), as applicable, (y) no later than five Business Days after the property of Pool 2 has been sold in connection with the Pool 2 Auction Call in accordance with Section 7.01(c), or (z) upon the final payment or other liquidation of the last Mortgage Loan or REO Property in the related Mortgage Pool. 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 related 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 related 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 related Certificates. Upon any termination pursuant to Section 7.01(e), 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)

In the event of any termination of the Trust Fund or portion thereof pursuant to Section 7.01(b), 7.01(c) or 7.01(d), the REMIC holding the related Mortgage Loans shall be liquidated in accordance with the following additional requirements, unless the Trustee seeks (at the request of the party purchasing the Mortgage Loans pursuant to Section 7.01(b) ), 7.01(c) or 7.01(d), and subsequently receives, an Opinion of Counsel (at the expense of such purchasing party), 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 result in an Adverse REMIC Event:

(i)

Within 89 days prior to the time of the making of the final payment on the related Certificates, (and upon notification by the Master Servicer that it intends to exercise its option to cause the termination of the Trust Fund, if such termination is pursuant to Section 7.01(b) or 7.01(d)), the Trustee shall adopt a plan of complete liquidation of REMIC 1 or REMIC 2, as applicable, meeting the requirements of a qualified liquidation under the REMIC Provisions;

On the date specified for final payment of the related Certificates, the Trustee shall make final distributions of principal and interest on the Certificates in accordance with Section 5.02 and, after payment of, or provision for any outstanding expenses, distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand with respect to REMIC 1 or REMIC 2, as applicable, after such final payment (other than cash retained to meet claims), and such REMIC shall terminate at that time;

(iv)

In no event may the final payment on the related Certificates or the final distribution or credit to the Holders of the Residual Certificates be made after the 89th day from the date on which the plan of complete liquidation is adopted; and

(v)

Upon the termination of a REMIC pursuant to this paragraph (a), if REMIC 1 and REMIC 2 are not outstanding following such termination, REMIC 3 shall be terminated in accordance with the following additional requirements, unless the Trustee has received an Opinion of Counsel to the effect that the failure to comply with the requirements of this Section will not result in an Adverse REMIC Event:

(A)

concurrently with the adoption of the plan of complete liquidation of REMIC 1 or REMIC 2, as applicable and as set forth above, the Trustee shall adopt a plan of complete liquidation of the REMIC 3; and

(B)

By its acceptance of a Residual Certificate, each Holder thereof hereby agrees to accept each plan of complete liquidation adopted by the Trustee under this Section and to take such other action in connection therewith as may be reasonably requested by the Trustee, the Master Servicer or any Servicer.

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 Percentage Interest) of Certificates of each Class affected thereby 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.

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 the 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.

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.

The Master Servicer Errors and Omissions Insurance Policy and the Master Servicer 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 and shall by its terms not be cancelable without thirty days’ prior written notice to the Trustee, the Master Servicer shall provide the Trustee upon request, with a copy of such policy and fidelity bond. The Master Servicer shall (i) require each Servicer to maintain an Errors and Omissions Insurance Policy and a Servicer 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 such policies and of the certificates and notices referred to in clause (ii) to the Trustee upon request.

(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. The total losses, regardless of whether claims are filed with the applicable insurer or surety, shall be disclosed in such reports together with the amount of such losses covered by insurance. If a bond or insurance claim report is filed with any of such bonding companies or insurers, the Master Servicer shall promptly furnish a copy of such report to the Trustee. Any amounts relating to the Mortgage Loans collected by the Master Servicer under any such bond or policy shall be promptly remitted by the Master Servicer to the Trustee for deposit into the Certificate Account.

Such financial statements shall include a balance sheet, income statement, statement of retained earnings, statement of additional paid in capital, statement of changes in financial position and all related notes and schedules and shall be in comparative form, certified by a nationally recognized firm of Independent Accountants to the effect that such statements were examined and prepared in accordance with generally accepted accounting principles applied on a basis consistent with that of the preceding year.

Section 9.04

Power to Act; Procedures.

(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 the 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 or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee, 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 (to the extent permitted in the related Servicing Agreement), 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 successor 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 an Adverse REMIC Event. 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 under the applicable Servicing Agreement, is hereby authorized and empowered by the Trustee when the Master Servicer or such 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 to allow such 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 the 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. 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.

(b)

In master servicing and administering the Mortgage Loans, the Master Servicer shall employ procedures, and shall exercise the same care that it customarily employs and exercises 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 (but not any Prepayment Premium) 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 such Servicer (if required by the applicable Servicing Agreement) to make 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, in the reasonable judgment of the Master Servicer or 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 (b) if the prepayment is not the result of a refinancing 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 Service shall have provided or caused to be provided to the Trustee an Opinion of Counsel (if required by the applicable Servicing Agreement) (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.

Section 9.05

Enforcement of Servicer’s and Master Servicer’s Obligations.

(a)

Each Servicing Agreement requires the applicable Servicer, respectively, 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 actions taken or to be taken by a Servicer on behalf of the Master Servicer. Any fees and other amounts payable to a Servicer shall be deducted from amounts remitted to the Master Servicer by such 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 use its reasonable best efforts to enforce the obligations of each Servicer under the related Servicing Agreement, and shall, upon obtaining actual knowledge of the failure of a Servicer to perform its obligations in accordance therewith, to the extent that such non-performance of such obligations would have a material adverse effect on a Mortgage Loan, the Trust Fund or the Certificateholders (determined in the case of the Class 1-A3A, Class 1-A5B and Class 1-A6 Certificates without regard to the Certificate Insurance Policy), terminate the rights and obligations of such Servicer thereunder and either act as servicer of the related Mortgage Loans or cause the other parties hereto to enter into a Servicing Agreement (and such parties hereby agree to execute and deliver any such successor 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 (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, (ii) from a specific recovery of costs, expenses or attorneys’ fees against the party against whom such enforcement is directed, and then, (iii) to the extent that such amounts are insufficient to reimburse the Master Servicer for the costs of such enforcement, 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 to deposit therein any collections of amounts received with respect to amounts due for taxes, assessments, water rates, Standard Hazard Insurance Policy premiums, Payaheads, if applicable, 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 or the applicable Servicer has determined that the funds so advanced are recoverable from escrow payments, reimbursement pursuant to Section 4.02 or otherwise.

(b)

Costs incurred by the Master Servicer or by any Servicer 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 as a Servicing Advance by the Master Servicer pursuant to Section 4.02.

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 provide for the servicing of the Mortgage Loans by a successor Servicer to be appointed as provided in the applicable Servicing Agreement.

The parties acknowledge that notwithstanding the preceding sentence, there may be a transition period, not to exceed 90 days, in order to effect the transfer of servicing to a successor Servicer. The Master Servicer shall be entitled to be reimbursed from each Servicer (or by the Trust Fund, if the Servicer is unable to fulfill its obligations hereunder) for all costs associated with the transfer of servicing from the predecessor servicer, including without limitation, any costs or expenses associated with the complete transfer or all servicing data and the completion, correction or manipulation of such servicing data, as may be required by the Master Servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the Master Servicer to service the Mortgage Loans properly and effectively.

(b)

If the Master Servicer acts as a successor 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 the related Servicing Agreement, 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.

(c)

If the Master Servicer acts as a successor Servicer, it will have no obligation to make an Advance if it determines in its reasonable judgment that such Advance is non-recoverable. To the extent that the Master Servicer is unable to find a successor Servicer that is willing to service the Mortgage Loans for the Servicing Fee because of the obligation of the Servicer to make Advances regardless of whether such Advance is recoverable, the applicable Servicing Agreement may be amended to provide that the successor Servicer shall have no obligation to make an Advance if it determines in its reasonable judgment that such Advance is non-recoverable and provides an Officer’s Certificate to such effect to the Master Servicer and the Trustee.

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. 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 any Servicer 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 Any Servicer and Trustee or Depositor.

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

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 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, 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; Easements.

(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 cause the related Servicer 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 collectability 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 Master Servicer of a notification that payment in full has been or will be escrowed in a manner customary for such purposes, the Master Servicer shall, or shall 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 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 hereof have been or will be so deposited) of a Servicing Officer and shall request (on the form attached hereto as Exhibit C or on the form attached to the related Custodial Agreement) the Trustee or the applicable Custodian, to deliver to the applicable Servicer the related Mortgage File; provided, however, that 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, and to the extent that such a request, on its face, originates from a Servicing Officer, no original signature shall be required. Upon receipt of such certification and request, the Trustee or the applicable Custodian (with the consent, and at the direction of the Trustee), 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. Upon any such payment in full, the Master Servicer is authorized, and each Servicer, to the extent such authority is provided for 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 any Mortgage Loan and in accordance with Accepted Servicing Practices and the applicable Servicing Agreement, the Trustee shall execute such 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 of Exhibit C, release the related Mortgage File held in its possession or control to the Master Servicer (or the applicable Servicer).

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 or any Servicing Agreement (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or released to the Mortgagor in accordance with the applicable Servicing Agreement) shall be deposited into the 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.

Section 9.17

Presentment of Claims and Collection of Proceeds.

The Master Servicer 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.

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 noncoverage under any applicable Primary Mortgage Insurance Policy of any loss which, but for the actions of such Master Servicer or such 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 knowingly 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 in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable.

(b)

The Master Servicer agrees, to the extent provided in each Servicing Agreement, 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 the applicable Custodian) 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 the applicable Custodian) 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 each Servicer to deliver to the Trustee (or the applicable Custodian), 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 or any 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. Servicing compensation in the form of assumption fees, if any, late payment charges, as collected, if any, or otherwise (but not including any Prepayment Premium) 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 to the extent that payments have been received with respect to the applicable Mortgage Loan. 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 compensation. The provisions of this Section 9.21 are subject to the provisions of Section 6.14.

Section 9.22

REO Property.

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 cause the applicable Servicer, to the extent provided in the applicable Servicing Agreement 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 each Servicer, upon the final disposition of any REO Property, shall be entitled to reimbursement for any related unreimbursed Advances and other 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 Net 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 Master Servicer Remittance Date.

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. No such resignation shall become effective until a period of time not to exceed 90 days after the Trustee receives written notice thereof from the Master Servicer and 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.

The Depositor, the Certificate Insurer 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, the Certificate Insurer 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)

REMIC elections as set forth in the Preliminary Statement shall be made 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. The regular interests and residual interest in each REMIC shall be as designated in the Preliminary Statement.

(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 represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto. 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 other reports as required by Section 6.20 and this Section.

(d)

The Trustee shall prepare, the Trustee shall sign, and the Trustee will file, all of each REMIC’s federal and applicable state tax and information returns as such REMIC’s direct representative. As used herein, applicable state tax and information returns shall mean 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 by the delivery to the Trustee of an Opinion of Counsel to such effect, or 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.

(e)

The Trustee or its designee 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 pursuant to Treasury Regulation 1.860E-2(a)(5) and any person designated in Section 860E(e)(3) of the Code and (ii) to the Certificateholders such information or reports as are required by the Code or REMIC Provisions.

The Trustee shall be entitled to receive reasonable compensation from the Trust Fund for the performance of its duties under this subsection (e); provided, however, that such compensation shall not exceed $5,000 per year.

(f)

The Trustee, the Master Servicer and the Holders of Certificates shall take any action, within their respective control and scope of their duties, or cause any REMIC to take any action necessary to create or maintain the status of any REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. Neither the Trustee, the Master Servicer nor the Holder of any Residual Certificate shall knowingly 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 their respective control and scope of their duties, that, under the REMIC Provisions, if taken or not taken, as the case may be, could result in 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 result in an Adverse REMIC Event. 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, 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 that such taxes are 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 any 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 any 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.

(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 an Officer’s Certificate stating, without regard to any actions taken by any party other than the Trustee, the Trustee’s compliance with provisions of this Section 10.01.

(l)

The Trustee shall treat the Reserve Fund as an outside reserve fund within the meaning of Treasury Regulation 1.860G-2(h) that is owned by the Holder of the Class 1-X Certificate and that is not an asset of any REMIC. The Trustee shall treat the rights of the Certificateholders (other than the Holders of the Class 1-X, Class R and Class P Certificates) to receive Net Funds Cap Shortfalls and any applicable Unpaid Net Fund Cap Shortfalls Payments as rights in an interest rate cap contract written by the Class 1-X Certificateholder in favor of such Certificateholders. Thus, each Certificateholder (other than the Holders of the Class 1-X, Class R and Class P Certificates) shall be treated as representing not only ownership of regular interests in the Upper Tier REMIC, but also ownership of an interest in an interest rate cap contract. For tax purposes the interest rate cap contract will be deemed to have a value of $20,000.

(m)

[Reserved]

(n)

Notwithstanding the priority and sources of payments set forth in Article 5 hereof or otherwise, the Trustee shall account for all distributions with respect to a Class of Certificates in amounts that differ from those payable pursuant to the regular interest in the Upper Tier REMIC corresponding to such Class as amounts paid or received (as appropriate) pursuant to the interest rate cap contracts provided for in this Section. In no event shall any such amounts be treated as payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1).

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) result in an Adverse REMIC Event, (b) affect the distribution of interest or principal on the Certificates, or (c) result in the encumbrance of the assets transferred or assigned to the Trust Fund (except pursuant to the provisions of this Agreement).

Section 10.03

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

Upon the occurrence of an Adverse REMIC Event due to the negligent performance by the Trustee of its duties and obligations set forth herein, the Trustee shall indemnify the Holder of the related Residual Certificate or the Trust Fund, as applicable, 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, the Class 1-X or Class R Certificateholder, as applicable, nor 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 or any Servicing Agreement, (2) for any Losses other than arising out of a negligent performance by the Trustee of 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).

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, knowingly permit any Servicer to, rent, lease, or otherwise earn income on behalf of any REMIC with respect to any REO Property which might cause an Adverse REMIC Event 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 result in an Adverse REMIC Event.

(b)

The Master Servicer shall cause the applicable Servicer (to the extent provided in its Servicing Agreement) 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 of its acquisition by the Trust Fund unless the Master Servicer has received a grant of extension from the Internal Revenue Service to the effect that, under the REMIC Provisions, the REMIC may hold REO Property for a longer period without causing an Adverse REMIC Event. If the Master Servicer has received such an extension, then the Master Servicer, acting on the Trustee’s 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 Master Servicer has not received such an extension and the Master Servicer or the applicable Servicer, acting on behalf of the Trustee hereunder, is unable to sell the REO Property within 33 months after its acquisition by the Trust Fund or if the Master Servicer has received such an extension, and the Master Servicer or the applicable Servicer is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Master Servicer shall cause the applicable Servicer, before the end of the three year period or the Extended Period, as applicable, to (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 applicable 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.

ARTICLE XI

Binding Nature of Agreement; Assignment.

This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

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.

Section 11.03

Amendment.

(a)

This Agreement may be amended from time to time by the Depositor, the Master Servicer and the Trustee, and without notice to or the consent of any of the Holders, (i) to cure any ambiguity, (ii) to cause the provisions herein to conform to or be consistent with or in furtherance of the statements made with respect to the Certificates, the Trust Fund or this Agreement in any Offering Document, or to correct or supplement any provision herein which may be inconsistent with any other provisions herein or with the provisions of any Servicing Agreement, (iii) to make any other provisions with respect to matters or questions arising under this Agreement or (iv) to add, delete, or amend any provisions to the extent necessary or desirable to comply with any requirements imposed by the Code and the REMIC Provisions. No such amendment effected pursuant to the preceding sentence shall, as evidenced by an Opinion of Counsel, result in an Adverse REMIC Event, nor shall such amendment effected pursuant to clause (iii) of such sentence adversely affect in any material respect the interests of any Holder (without regard to the Certificate Insurance Policy). Prior to entering into any amendment without the consent of Holders pursuant to this paragraph, the Trustee shall be provided with an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that such amendment is permitted under this Section. 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 the then current rating assigned to the Certificates (in the case of the Class 1-A3A, Class 1-A5B and Class 1-A6 Certificates, determined without regard to the Certificate Insurance Policy).

(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 cause an Adverse REMIC Event; 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 Percentage Interest) 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.

Notwithstanding the foregoing, the Certificate Insurer shall be required to consent (such consent not to be unreasonably withheld) to any amendment that has a material adverse effect in any respect on the rights and interests of the Certificate Insurer hereunder.

Section 11.04

Voting Rights.

In addition, the ability of the Seller to transfer or assign its rights and delegate its duties under the Servicing Agreement or to transfer the servicing thereunder, from time to time with respect to any Mortgage Loan or group of Mortgage Loans, to a successor servicer shall be subject to the following conditions:

(i)

satisfaction of the conditions to such transfer as set forth in the Servicing Agreement including, without limitation, receipt of written consent of the Master Servicer to such transfer;

Such successor servicer must be qualified to service loans for FNMA or FHLMC, and must be a member in good standing of MERS;

(v)

If the successor servicer is not a Servicer of Mortgage Loans at the time of the transfer, there must be delivered to the Trustee and the Master Servicer 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 (determined in the case of the Class 1-A3A, Class 1-A5B and Class 1-A6 Certificates, without regard to the Certificate Insurance Policy); and

(vi)

The Seller shall, at its cost and expense, take such steps, or cause the transferring Servicer to take such steps, as may be necessary or appropriate to effectuate and evidence the transfer of the servicing of the specified Mortgage Loans to such successor or replacement 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 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 or replacement servicer; (B) prior to the effective date of such transfer of servicing, the 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 Seller shall cause the prior Servicer to deliver to the successor or replacement 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 Seller shall cause the prior Servicer to transfer to the successor or replacement servicer, or, if such transfer occurs after a Servicer Remittance Date but before the next succeeding Master Servicer Remittance Date, to the Trustee, all funds held by the prior Servicer in respect of the Mortgage Loans; (E) on or prior to the effective date of such transfer of servicing, the Seller shall cause the prior Servicer to, after the effective date of the transfer of servicing to the successor or replacement servicer, continue to forward to such successor or replacement 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 or replacement servicer of the source and proper application of each such payment or recovery; and (F) the Seller shall cause the prior Servicer to, after the effective date of transfer of servicing to the successor or replacement servicer, continue to cooperate with the successor or replacement servicer to facilitate such transfer in such manner and to such extent as the successor or replacement servicer may reasonably request. Notwithstanding the foregoing, the prior Servicer shall be obligated to perform the items listed above to the extent provided in the Servicing Agreement.

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 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 May 1, 2004 by and among the Depositor, Aurora Loan Services Inc., as Master Servicer, and LaSalle Bank National Association, as Trustee (the “Trustee”), 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.

We further understand that the Privately Offered Certificates purchased by us will bear a legend to the foregoing effect.

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