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, the Securities Administrator 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, to the extent provided herein, any NIMS Insurer. The Depositor, the Trustee, the Master Servicer, the Securities Administrator and the Credit Risk Manager 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 Basis Risk Reserve Fund, (ii) the Basis Risk Cap and (iii) the Class X Cap) be treated for federal income tax purposes as comprising four real estate mortgage investment conduits (each a “REMIC” or, in the alternative, REMIC 1, REMIC 2, REMIC 3 and REMIC 4; REMIC 4 also being referred to as the “Upper Tier REMIC”). Each Certificate, other than the Class X Certificate, the Class P Certificate, and Class R Certificate represents ownership of a regular interest in the Upper Tier REMIC for purposes of the REMIC Provisions. The Class P Certificate represents ownership of a regular interest in REMIC 2. The Class X Certificate represents ownership of two regular interests in the Upper Tier REMIC as described in note 13 of the table below for such REMIC. In addition, each Certificate, other than the Class R, Class A-IO, Class X and Class P Certificates, represents the right to receive payments with respect to any Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls from the Basis Risk Reserve Fund pursuant to Section 5.06. The Class R Certificate represents ownership of the sole class of residual interest in each of REMIC 1, REMIC 2, REMIC 3 and the Upper Tier REMIC for purposes of the REMIC Provisions.

The Upper Tier REMIC shall hold as its assets the several Classes of uncertificated Lower Tier Interests in REMIC 3, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 3. REMIC 3 shall hold as its assets the several Classes of uncertificated Lower Tier Interests in REMIC 2, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 2. REMIC 2 shall hold as its assets the several Classes of uncertificated Lower Tier Interests in REMIC 1, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 1. REMIC 1 shall hold as its assets the property of the Trust Fund other than the Lower Tier Interests in REMIC 1, REMIC 2 and REMIC 3, the Basis Risk Reserve Fund, the Basis Risk Cap, and the Class X Cap.

The startup day for each REMIC created hereby for purposes of the REMIC Provisions is the Closing Date. In addition, for purposes of the REMIC Provisions, the latest possible maturity date for each regular interest in each REMIC created hereby is the Latest Possible Maturity 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 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 on behalf of the Trustee, will execute and deliver to the Depositor, the Master Servicer, the Trustee and any NIMS Insurer 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, the Master Servicer and any NIMS Insurer an Interim Certification in the form annexed hereto as Exhibit B-2 (or in the form annexed to the applicable Custodial Agreement as Exhibit B 2, as applicable) to the effect that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan prepaid in full or any Mortgage Loan specifically identified in such certification as not covered by such certification), (i) all of the applicable documents specified in Section 2.01(b) are in its possession and (ii) such documents have been reviewed by it and appear to relate to such Mortgage Loan. The Trustee, or the applicable Custodian on behalf of the Trustee, shall 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 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 Depositor and the Master Servicer.

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 Trustee 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, the Master Servicer and any NIMS Insurer 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, 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.

(g)

Upon execution of this Agreement, the Depositor hereby delivers to the Trustee and the Trustee acknowledges a receipt of the Mortgage Loan Sale Agreement, each Servicing Agreement and each Bulk PMI Policy.

Section 2.03

Representations and Warranties of the Depositor.

(a)

The Depositor hereby represents and warrants to the Trustee, for the benefit of Certificateholders and to the Master Servicer, the Securities Administrator and any NIMS Insurer as of the Closing Date or such other date as is specified, that:

(i)

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

(ii)

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

(iii)

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

(iv)

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

(v)

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

(vi)

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

(b)

The representations and warranties of each Transferor with respect to the related Mortgage Loans in the applicable Transfer Agreement, which have been assigned to the Trustee hereunder, were made as of the date specified in the applicable Transfer Agreement (or underlying agreement, if such Transfer Agreement is in the form of an assignment of a prior agreement). To the extent that any fact, condition or event with respect to a Mortgage Loan constitutes a breach of both (i) a representation or warranty of the applicable Transferor under the applicable Transfer Agreement and (ii) a representation or warranty of the Seller under the Mortgage Loan Sale Agreement, the only right or remedy of the Trustee, any Certificateholder or any NIMS Insurer 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 otherwise provided in the Mortgage Loan Sale Agreement, the Seller shall not have any 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) of the Depositor 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 Master Servicer, the Securities Administrator or the Trustee of a breach of any of such representations and warranties that adversely and materially affects the value of the related Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties. Within 90 days of the discovery of a breach of any representation or warranty given to the Trustee by the Depositor 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 and any NIMS Insurer. As provided in the Mortgage Loan Sale Agreement, 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 each 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 Trustee 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 related 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 Securities Administrator, the Trustee, the Depositor, and NIMS Insurer 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 Master Servicer, the Securities Administrator, the Depositor, any NIMS Insurer and any Certificateholder may sustain in connection with any actions of such 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 its 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 a 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 granting language substantially comparable to that set forth in the first paragraph of Section 2.01(a); and (ii) the Depositor will be deemed to have made, with respect to such Qualifying Substitute Mortgage Loan, each of the representations and warranties made by it with respect to the related Deleted Mortgage Loan. As soon as practicable after the delivery of any Qualifying Substitute Mortgage Loan hereunder, the Trustee, at the expense of the Depositor and at the direction and with the cooperation of the applicable Servicer, shall (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 and any NIMS Insurer has received an Opinion of Counsel addressed to the Trustee (at the expense of the party seeking to make the substitution) that, under current law, such substitution will not cause 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 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, each of 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 Notional Principal Amount, as applicable, or in the Percentage Interests, specified herein. Each Class of Book-Entry Certificates will be issued in the minimum denominations in Certificate Principal Amount (or Notional Amount) specified in the Preliminary Statement hereto and in integral multiples of $1 in excess thereof. The Class P, Class X Certificate and the Class R Certificate shall each 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.

(c)

[Reserved].

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, any NIMS Insurer 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 or Percentage Interest 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, 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.

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

(i)

The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is (x) to the Depositor or the Placement Agent, an affiliate (as defined in Rule 405 under the 0000 Xxx) of the Depositor or the Placement Agent 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 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 satisfactory to the Trustee, to the effect that the purchase and holding of such a Certificate will not constitute or result in prohibited transactions under Title I of ERISA or Section 4975 of the Code and will not subject the Trustee, the Master Servicer, the Securities Administrator, the NIMS Insurer or the Depositor to any obligation in addition to those undertaken in the Agreement; provided, however, that the Trustee will not require such certificate or opinion in the event that, as a result of a change of law or otherwise, counsel 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 Securities Administrator, any 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 any such 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, the Securities Administrator, any NIMS Insurer 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 a Responsible Officer of 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, but not obligated, 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.

(h)

[Reserved].

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 and the Authenticating Agent and any NIMS Insurer 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. 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 Securities Administrator, the Trustee, the Certificate Registrar, any NIMS Insurer 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 Securities Administrator, the Trustee, the Certificate Registrar, any NIMS Insurer 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, subject to the consent of the NIMS Insurer, 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 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.

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 (or in the case of Simple Interest Mortgage Loans, representing scheduled interest payments, but actual principal 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 on the earlier of the applicable Master Servicer Remittance Date and 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 and Late Collections, on the Mortgage Loans;

(ii)

all payments on account of interest on the Mortgage Loans, including Prepayment Premiums, in all cases, net of the Servicing Fee and the PMI Insurance Premiums, if any, 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)

any Seller Remittance Amounts remitted by a Servicer;

(v)

all Insurance Proceeds;

(vi)

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

The Master Servicer shall also deposit from its own funds into the Collection Account (to the extent not already received from the related Servicer), without right of reimbursement, except from Net Simple Interest Excess, an amount equal to any Net Simple Interest Shortfall (to the extent not offset by Net Simple Interest Excess) for the related Collection Period.

(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 Securities Administrator, 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 Holders of the Structured Asset Investment Loan Trust Mortgage Pass-Through Certificates, Series 2003-BC9. 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, subject to Section 5.05 hereof, 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.

(viii)

to the extent not paid by a Servicer pursuant to the related Servicing Agreement, any premium due under any Bulk PMI Policy;

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 Securities Administrator 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 Securities Administrator thereto shall be prior to the rights of the Certificateholders; and

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 Deposit Date, the Securities Administrator, 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 Securities Administrator 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 Securities Administrator shall be entitled to be reimbursed from the Certificate Account for Advances made by it pursuant to this Section 5.04 as if it were the Master Servicer.

Section 5.05

Compensating Interest Payments.

The amount of the aggregate Master Servicing Fees payable to the Master Servicer in respect of any Distribution Date shall be reduced (but not below zero) by the amount of any Compensating Interest Payment for such Distribution Date, but only to the extent that Prepayment Interest Shortfalls relating to such Distribution Date are required to be paid but not actually paid by the Servicers on the applicable Servicer Remittance Date. Such amount shall not be treated as an Advance and shall not be reimbursable to the Master Servicer.

Section 5.06

Basis Risk Reserve Fund.

(a)

On the Closing Date, the Trustee shall establish and maintain in its name, in trust for the benefit of the holders of the Certificates, a Basis Risk Reserve Fund, into which LBH shall deposit $1,000. In addition, the Trustee shall hold the Basis Risk Cap as an asset in the Basis Risk Reserve Fund. The Basis Risk 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)

The Trustee shall account for the Cap Agreement as though it comprised two component cap agreements – the Basis Risk Cap and the Class X Cap. The Class X Cap shall not be an asset of the Trust Fund or the Basis Risk Reserve Fund. On each Distribution Date the Trustee shall distribute to the Class X Certificateholder pursuant to Section 5.02(f)(iii)(H) of this Agreement any payments made by the Cap Provider to the Trust Fund for such Distribution Date with respect to the Class X Cap, and the Trustee shall not treat such payments as amounts on deposit in the Basis Risk Reserve Fund for purposes of determining the Required Reserve Fund Amount for any Distribution Date. 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 Basis Risk Cap, (b) any amounts then on deposit in the Basis Risk Reserve Fund, including any earnings thereon, in respect of the Basis Risk Cap and (c) the Basis Risk Payment, if any, for such Distribution Date. On any Distribution Date, any amounts that the Trustee is not required to distribute from the Basis Risk Reserve Fund pursuant to Section 5.02(f)(iii) of this Agreement shall remain on deposit in the Basis Risk Reserve Fund.

(c)

Funds in the Basis Risk Reserve Fund shall be invested in Eligible Investments. The Class X Certificate shall evidence ownership of the Basis Risk Reserve Fund for federal income tax purposes and LBH on behalf of the Holder 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. In the absence of written instructions from LBH as to investment of funds on deposit in the Basis Risk Reserve Fund, such funds shall be invested in the Xxxxx Fargo Prime Money Market Fund Investment Account.

(b)

Each of the Trustee and the Securities Administrator, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee or the Securities Administrator which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they are on their face in the form required by this Agreement; provided, however, that neither the Trustee nor the Securities Administrator shall 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, any Servicer or the Credit Risk Manager to the Trustee or the Securities Administrator pursuant to this Agreement, and shall not be required to recalculate or verify any numerical information furnished to the Trustee or the Securities Administrator pursuant to this Agreement.

If the Trustee shall not have timely received amounts to be remitted with respect to the Mortgage Loans from the Master Servicer, the Trustee shall request the Master Servicer to make such distribution as promptly as practicable or legally permitted. If the Trustee shall subsequently receive any such amount, it may withdraw such request.

Section 6.14

(a)

The occurrence of any one or more of the following events shall constitute an “Event of Default”:

(i)

A decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding up or liquidation of its affairs, shall have been entered against the Master Servicer, and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days or any Rating Agency reduces or withdraws or threatens to reduce or withdraw the rating of the Certificates because of the financial condition or loan servicing capability of such Master Servicer; or

(iv)

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

(v)

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

(vi)

The Master Servicer shall be dissolved, or shall dispose of all or substantially all of its assets, or consolidate with or merge into another entity or shall permit another entity to consolidate or merge into it, such that the resulting entity does not meet the criteria for a successor servicer as specified in Section 9.27 hereof; or

(vii)

If a representation or warranty set forth in Section 9.14 hereof shall prove to be incorrect as of the time made in any respect that materially and adversely affects the interests of the Certificateholders, and the circumstance or condition in respect of which such representation or warranty was incorrect shall not have been eliminated or cured within 30 days after the date on which written notice of such incorrect representation or warranty shall have been given to the Master Servicer by the Trustee or the Securities Administrator, or to the Master Servicer, the Securities Administrator and the Trustee by the Holders of more than 50% of the Aggregate Voting Interests of the Certificates or by any NIMS Insurer; or

(viii)

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, any NIMS Insurer 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 acquires such actual knowledge; or

(x)

After receipt of notice from the Trustee or any NIMS Insurer, any failure of the Master Servicer to remit to the Securities Administrator any payment required to be made to the Securities Administrator for the benefit of Certificateholders under the terms of this Agreement, including any Advance, on any Master Servicer Remittance Date which such failure continues unremedied for a period of one Business Day after the date upon which 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 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 (with a copy to the Securities Administrator) may, and shall, if so directed by Certificateholders evidencing more than 50% of the Class Principal Amount (or Class Notional 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 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 of 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 Securities Administrator and upon receipt of written notice by the Securities Administrator from the Trustee pursuant to and under the terms of this Agreement; provided, however, 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 the Master Servicing obligations to the Securities Administrator. The Securities Administrator 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 and the Securities Administrator 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 Securities Administrator or its designee all documents and records in electronic or other form reasonably requested by it to enable the Securities Administrator or its designee to assume the defaulting Master Servicer’s functions hereunder and the transfer to the Securities Administrator 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 Securities Administrator 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 Securities Administrator and 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 Securities Administrator to correct any errors or insufficiencies in the servicing data or otherwise to enable the Securities Administrator 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 and the Securities Administrator and the Trustee, as applicable, 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 for any such expense incurred by the Trust; and provided, further, that the Securities Administrator 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 to the extent such reimbursement relates to the period prior to such Master Servicer’s termination.

If any Event of Default shall occur, the Trustee, upon a Responsible Officer of the Trustee becoming aware of the occurrence thereof, shall promptly notify the Securities Administrator, any NIMS 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)

On and after 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 and within a period of time not to exceed 90 days after the Securities Administrator receives written notice from the Trustee pursuant to Section 6.14(a) or Section 9.28, the Securities Administrator, 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 or the Trustee’s failure to provide information required by this Agreement shall not be considered a default by the Securities Administrator or the Trustee hereunder. In addition, the Securities Administrator 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 Securities Administrator receives written notice from the Trustee pursuant to Section 6.14(a) or Section 9.28, as applicable. The Securities Administrator shall have no liability relating to the representations and warranties of the Master Servicer set forth in Section 9.14. In the Securities Administrator’s capacity as such successor, the Securities Administrator shall have the same limitations on liability herein granted to the Master Servicer. As compensation therefor, the Securities Administrator 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 Securities Administrator may, if it shall be unwilling to continue to so act, or shall, if it is unable to so act, request the Trustee to appoint, 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 the Master Servicer hereunder. Any entity designated by the Trustee or the Securities Administrator as a successor master servicer may be an Affiliate of the Trustee or the Securities Administrator; provided, however, that, unless such Affiliate meets the net worth requirements and other standards set forth herein for a successor master servicer, the Trustee or the Securities Administrator, 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 or the Securities Administrator 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, the Securities Administrator 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, the Securities Administrator 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, the Securities Administrator 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, the Securities Administrator 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, the Securities Administrator 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 Securities Administrator as required by this Agreement or (iv) restrictions imposed by any regulatory authority having jurisdiction over the Master Servicer. Neither the Securities Administrator 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 Trustee to deliver, or any delay in delivering cash, documents or records to it, or (ii) the failure of Trustee to cooperate as required by this Agreement.

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 any NIMS Insurer and the Certificateholders (including the institution and prosecution of all judicial, administrative and other proceedings and the filings of proofs of claim and debt in connection therewith). Except as otherwise expressly provided in this Agreement, no remedy provided for by this Agreement shall be exclusive of any other remedy, and each and every remedy shall be cumulative and in addition to any other remedy, and no delay or omission to exercise any right or remedy shall impair any such right or remedy or shall be deemed to be a waiver of any Event of Default.

Section 6.16

Waiver of Defaults.

More than 50% of the Aggregate Voting Interests of Certificateholders, with the consent of any NIMS Insurer 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, with the consent of any NIMS Insurer. 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 Securities Administrator, the Certificateholders at their respective addresses appearing on the Certificate Register and any NIMS Insurer. 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 Securities Administrator, any NIMS Insurer and 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, with the consent of any NIMS Insurer, 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 or any NIMS Insurer, unless such Certificateholders or any NIMS Insurer 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 acceptable to any NIMS Insurer, 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 the Trustee or the Securities Administrator 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 or the Securities Administrator, as applicable, shall give notice thereof to the Master Servicer and any NIMS Insurer and the Trustee or Securities Administrator, as applicable.

Section 6.20

Preparation of Tax Returns and Other Reports.

(a)

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

(b)

The Securities Administrator shall prepare and file with the Internal Revenue Service (“IRS”), on behalf of the Trust Fund and each of REMIC 1, REMIC 2, REMIC 3 and REMIC 4, an application for an employer identification number on IRS Form SS 4 or by any other acceptable method. The Securities Administrator shall also file a Form 8811 as required. The Securities Administrator, upon receipt from the IRS of the Notice of Taxpayer Identification Number Assigned, shall upon request promptly forward a copy of such notice to the Trustee and the Depositor. The Trustee shall have no obligation to verify the information in any Form 8811 or Form SS-4 filing.

(c)

The Depositor shall prepare or cause to be prepared the initial current report on Form 8-K. Thereafter, within 15 days after each Distribution Date, the Securities Administrator shall, in accordance with industry standards, file with the Securities and Exchange Commission (the “Commission”) via the Electronic Data Gathering and Retrieval System (XXXXX), a Form 8-K with a copy of the statement to the Certificateholders for such Distribution Date as an exhibit thereto. Prior to January 30, 2004, the Securities Administrator shall, in accordance with industry standards, file a Form 15 Suspension Notification with respect to the Trust Fund, if applicable. Prior to March 30, 2004, the Securities Administrator shall file (but will not execute) a Form 10-K, in substance conforming to industry standards, with respect to the Trust Fund. The Form 10-K shall include the certification required pursuant to Rule 13a-14 under the Securities and Exchange Act of 1934, as amended (the “Form 10-K Certification”) signed by an appropriate party or parties (which Form 10-K Certification the Securities Administrator shall not be required to sign). The Depositor hereby grants to the Securities Administrator a limited power of attorney to execute and file each Form 8-K on behalf of the Depositor. Such power of attorney shall continue until either the earlier of (i) receipt by the Securities Administrator from the Depositor of written termination of such power of attorney and (ii) the termination of the Trust Fund. The Depositor agrees to promptly furnish to the Securities Administrator, from time to time upon request, such further information, reports, and financial statements within its control related to this Agreement and the Mortgage Loans as the Securities Administrator reasonably deems appropriate to prepare and file all necessary reports, and financial statements within its control related to this Agreement and the Mortgage Loans as the Securities Administrator reasonably deems appropriate to prepare and file all necessary reports with the Commission. The Securities Administrator shall have no responsibility to file any items other than those specified in this section.

(d)

If so requested, the Securities Administrator shall sign a certification (in the form attached hereto as Exhibit Q) for the benefit of the Person(s) signing the Form 10-K Certification regarding certain aspects of such Form 10-K Certification (provided, however, that the Securities Administrator shall not be required to undertake an analysis of the accountant’s report attached as an exhibit to the Form 10-K).

(e)

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

ARTICLE VII

PURCHASE OF MORTGAGE LOANS AND

TERMINATION OF THE TRUST FUND

Section 7.01

Purchase of Mortgage Loans; Termination of Trust Fund Upon Purchase or Liquidation of All Mortgage Loans.

(a)

The respective obligations and responsibilities of the Trustee and the Master Servicer created hereby (other than the obligation of the Trustee to make payments to Certificateholders as set forth in Section 7.02, the obligation of the Master Servicer to make a final remittance to the Securities Administrator pursuant to Section 4.01, the obligation of the Securities Administrator to make a final remittance to the Trustee pursuant to Section 4.05 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 sale of the property held by the Trust Fund in accordance with Section 7.01(b) 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.

(b)

On any Distribution Date occurring on or after the Initial Optional Purchase Date, the Master Servicer, with the prior written consent of any NIMS Insurer and the Seller which consent shall not be unreasonably withheld, has the option to cause the Trust Fund to adopt a plan of complete liquidation pursuant to Section 7.03(a)(i) hereof to sell all of its property. The 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 Trust Fund shall be sold to the Master Servicer at a price (the “Termination Price”) equal to the sum of (i) 100% of the unpaid principal balance of each Mortgage Loan on the day of such purchase plus interest accrued thereon at the applicable Mortgage Rate with respect to any Mortgage Loan to the Due Date in the Collection Period immediately preceding the related Distribution Date to the date of such repurchase, (ii) the amount of any costs and damages incurred by the Trust Fund associated with any violation of any applicable federal, state, or local predatory or abusive lending law arising from or in connection with the origination of any Mortgage Loan purchased by the Master Servicer pursuant to this Section 7.01(b) and (iii) the fair market value of any REO Property and any other property held by any REMIC, such fair market value to be determined by an appraiser or appraisers mutually agreed upon by the Master Servicer, any NIMS Insurer and the Trustee. The Master Servicer, each Servicer (or the Trustee, if applicable) shall be reimbursed from the Termination Price for any Mortgage Loan or related REO Property for any Advances made or other amounts advanced with respect to the Mortgage Loans that are reimbursable to the Master Servicer or the Securities Administrator 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.

Section 7.02

Procedure Upon Termination of Trust Fund.

(a)

Notice of any termination pursuant to the provisions of Section 7.01, specifying the Distribution Date upon which the final distribution shall be made, shall be given promptly by the Trustee by first class mail to Certificateholders mailed upon (x) the sale of all of the property of the Trust Fund by the Trustee pursuant to Section 7.01(b) or (y) upon the final payment or other liquidation of the last Mortgage Loan or REO Property in the Trust Fund. Such notice shall specify (A) the Distribution Date upon which final distribution on the Certificates of all amounts required to be distributed to Certificateholders pursuant to Section 5.02 will be made upon presentation and surrender of the Certificates at the Corporate Trust Office, and (B) that the Record Date otherwise applicable to such Distribution Date is not applicable, distribution being made only upon presentation and surrender of the Certificates at the office or agency of the Trustee therein specified. The Trustee shall give such notice to the Master Servicer and the Certificate Registrar at the time such notice is given to Holders of the Certificates. Upon any such termination, the duties of the Certificate Registrar with respect to the Certificates shall terminate and the Trustee shall terminate or request the Master Servicer to terminate, the Collection Account it maintains, the Certificate Account and any other account or fund maintained with respect to the Certificates, subject to the Trustee’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment.

(b)

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

(c)

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

Section 7.03

Additional Trust Fund Termination Requirements.

(a)

Any termination of the Trust Fund shall be effected in accordance with the following additional requirements, unless the Trustee seeks (at the request of the party exercising the option to purchase all of the Mortgage Loans pursuant to Section 7.01(b)), and subsequently receives, an Opinion of Counsel (at the expense of such requesting party), addressed to the Trustee and any NIMS Insurer 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 Certificates, upon notification by the Master Servicer, any NIMS Insurer or an affiliate of the Seller that it intends to exercise its option to cause the termination of the Trust Fund, the Trustee shall adopt a plan of complete liquidation of the Trust Fund on behalf of each REMIC, meeting the requirements of a qualified liquidation under the REMIC Provisions;

(ii)

Any sale of the assets of the Trust Fund pursuant to Section 7.02 shall be a sale for cash and shall occur at or after the time of adoption of such a plan of complete liquidation and prior to the time of making of the final payment on the Certificates;

(iii)

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 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 furnish to the Master Servicer, upon request, with any powers of attorney empowering the Master Servicer or any Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, necessary or appropriate to enable the Master Servicer to master service the Mortgage Loans and carry out its duties hereunder and to allow each Servicer to service the Mortgage Loans, in each case in accordance with Accepted Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Master Servicer or any Servicer). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, then upon request of the Trustee the Master Servicer shall join with the Trustee in the appointment of a co trustee pursuant to Section 6.09 hereof. In no event shall the Master Servicer, 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. The Master Servicer shall indemnify the Trustee for any and all costs, liabilities and expenses incurred by the Trustee in connection with the negligent or willful misuse of such powers of attorney by the Master Servicer. 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 on behalf of the Trust Fund, be deemed to be the agent of the Trustee.

(b)

In master servicing and administering the Mortgage Loans, the Master Servicer shall employ procedures and exercise the same care that it customarily employs and exercises in master servicing and administering loans for its own account, giving due consideration to Accepted Servicing Practices where such practices do not conflict with this Agreement. Consistent with the foregoing, the Master Servicer may, and may permit any Servicer to, in its discretion (i) waive any late payment charge (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 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 and in the case of a waiver if a Prepayment Premium such waiver would maximize recovery of total proceeds, from the Mortgage Loan, taking into account the amount of the Prepayment Premium and the related Mortgage Loan and, (2) the Master Servicer shall have provided or (if required by the applicable Servicing Agreement) caused to be provided to the Trustee an Opinion of Counsel addressed to the Trustee (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 result in an Adverse REMIC Event.

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 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, any NIMS Insurer and the Certificateholders, shall enforce the obligations of each Servicer under the related Servicing Agreement, and shall, in the event that a Servicer fails to perform its obligations in accordance therewith, 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, the Master Servicer shall 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, the Trustee and the NIMS Insurer.

Section 9.08

Master Servicer Liable for Enforcement.

Notwithstanding any Servicing Agreement, the Master Servicer shall remain obligated and liable to the Trustee, any NIMS Insurer 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 and any NIMS Insurer. 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, any NIMS Insurer 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. It is furthermore understood and agreed by the parties hereto that the obligations of any Servicer are set forth in their entirety in such Servicer’s related Servicing Agreement and such Servicer has no obligations under and is not otherwise bound by the terms of this Agreement.

Section 9.10

Assumption of Servicing Agreement by Securities Administrator.

(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 Securities Administrator receives written notice from the Trustee pursuant to Section 6.14 or Section 9.28, as applicable, the Securities Administrator shall 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 Securities Administrator, its designee or any successor master servicer appointed by the Securities Administrator 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 Securities Administrator and any NIMS Insurer, and hereby agrees to indemnify and hold harmless the Securities Administrator and any NIMS Insurer from and against all costs, damages, expenses and liabilities (including reasonable attorneys’ fees) incurred by the Securities Administrator or any NIMS Insurer as a result of such liability or obligations of the Master Servicer and in connection with the Securities Administrator’s assumption (but not its performance, except to the extent that costs or liability of the Securities Administrator 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.

(b)

The Master Servicer that has been terminated shall, upon request of the Securities Administrator 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.

To the extent provided in the applicable Servicing Agreement, to the extent Mortgage Loans contain enforceable due on sale clauses, the Master Servicer shall cause the 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.

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 will, or will cause the related Servicer to, promptly notify the Trustee (or the applicable Custodian) and the Securities Administrator 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 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. 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 the Trustee shall have no 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). Such trust receipt shall obligate the Master Servicer or Servicer to return the Mortgage File to the Trustee or the applicable Custodian, as applicable, when the need therefor by the Master Servicer or Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that hereinabove specified, the trust receipt shall be released by the Trustee or the applicable Custodian, as applicable, to the Master Servicer (or the applicable Servicer).

Section 9.13

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

(a)

The Master Servicer shall transmit, or cause the applicable Servicer to transmit, to the Trustee such documents and instruments coming into the possession of the Master Servicer or such Servicer from time to time as are required by the terms hereof or of the applicable Servicing Agreement to be delivered to the Trustee or the applicable Custodian. Any funds received by the Master Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer or a Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit of the Trustee and the Certificateholders subject to the Master Servicer’s right to retain or withdraw from the Collection Account the Master Servicing Fee and other amounts provided in this Agreement and to the right of each Servicer to retain its Servicing Fee and other amounts as provided in the related Servicing Agreement. The Master Servicer shall, and shall (to the extent provided in the applicable Servicing Agreement) cause each Servicer to, provide access to information and documentation regarding the Mortgage Loans to the Trustee, any NIMS Insurer, their respective agents and accountants at any time upon reasonable request and during normal business hours, and to Certificateholders that are savings and loan associations, banks or insurance companies, the Office of Thrift Supervision, the FDIC and the supervisory agents and examiners of such Office and Corporation or examiners of any other federal or state banking or insurance regulatory authority if so required by applicable regulations of the Office of Thrift Supervision or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during normal business hours at the offices of the Master Servicer designated by it.

The Securities Administrator 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 Securities Administrator 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 Securities Administrator in fulfilling its duties hereunder (including its duties as tax return preparer). The Securities Administrator shall be entitled to reimbursement of expenses to the extent provided in clause (i) above from the Securities Administration Account, provided, however, the Securities Administrator 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 Securities Administrator shall prepare, and the Trustee shall sign and file, as instructed by the Securities Administrator, all of each REMIC’s federal and appropriate state tax and information returns as such REMIC’s direct representative. The expenses of preparing and filing such returns shall be borne by the Securities Administrator.

(e)

The Securities Administrator 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 Securities Administrator 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 Trustee such information as is necessary for the Trustee to provide to the Certificateholders such information or reports as are required by the Code or REMIC Provisions.

The Securities Administrator shall be entitled to receive reasonable compensation from the Trust 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 Securities Administrator, the Master Servicer and the Holders of Certificates shall take any action 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 Securities Administrator, the Master Servicer nor the Holder of any Residual Certificate shall knowingly take any action, cause any REMIC to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could result in an Adverse REMIC Event unless the Trustee, the Securities Administrator, any NIMS Insurer and the Master Servicer have received an Opinion of Counsel addressed to the Trustee (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 Securities Administrator, the Master Servicer, any NIMS Insurer 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, the Securities Administrator, the Master Servicer or any NIMS Insurer 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 Securities Administrator 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 Securities Administrator nor the Master Servicer shall enter into any arrangement by which any REMIC will receive a fee or other compensation for services.

(k)

On or before September 15 of each calendar year beginning in 2003, the Securities Administrator shall deliver to the Trustee and any NIMS Insurer an Officer’s Certificate stating, without regard to any actions taken by any party other than the Securities Administrator, the Securities Administrator’s compliance with provisions of this Section 10.01.

(l)

The Basis Risk Reserve Fund shall be treated as an outside reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h) that is owned by the Holder of the Class X Certificate and that is not an asset of any REMIC, and all amounts deposited into the Basis Risk Reserve Fund shall be treated as amounts distributed to the Class X Certificateholder. The rights of the holders of LIBOR Certificates to receive payments from the Basis Risk Reserve Fund shall be treated as rights in an interest rate cap contract written by the holder of the Class X Certificate in favor of the holders of the LIBOR Certificates. For this purpose, such rights include not only the rights with respect to Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls but also the rights of a holder of a Class 1-A1, Class 1-A2, Class 2-A, Class 3-A1, Class 3-A2, Class 3-A3, Class M1, Class M2, Class M3, Class M4, Class M5 or Class B Certificate to receive amounts in excess of the amounts payable on the regular interest in REMIC 4 corresponding to such Certificate. In this regard, on any REMIC Capped Distribution Date, the regular interests in REMIC 4 corresponding to the Class 1-A1, Class 1-A2, Class 2-A, Class 3-A1, Class 3-A2, Class 3-A3, Class M1, Class M2, Class M3, Class M4, Class M5 and Class B Certificates shall each be treated for purposes of compliance with the REMIC Provisions as bearing interest at a rate of 0.00%, and any interest actually distributed on a Class 1-A1, Class 1-A2, Class 2-A, Class 3-A1, Class 3-A2, Class 3-A3, Class M1, Class M2, Class M3, Class M4, Class M5 or Class B Certificate on such Distribution Date shall be treated as having been distributed on such Certificate pursuant to the interest rate cap contract written by the Class X Certificateholder. Thus, each Certificate (other than the Class A-IO, Class P, Class X and Class R Certificates) shall be treated as representing not only ownership of regular interests in REMIC 4, but also ownership of an interest in an interest rate cap contract. For tax purposes, the interest rate cap contract shall be deemed to have a value of $54,525.83.

(m)

In addition, the holders of the Class X Certificates shall be treated as having entered into a notional principal contract with respect to each holder of a Class A-IO Certificate. Pursuant to such notional principal contract, each holder of a Class X Certificate will be treated as having agreed to pay, on each Distribution Date, to the holders of Class A-IO Certificates an aggregate amount equal to the excess of (i) the amount payable on Class A-IO Certificates on such Distribution Date over (ii) the aggregate amount payable on such Distribution Date on the XX0-0-XXX-0, XX0-0-XXX-0, XX0-0-XXX-0, XX0-0-XXX-0, XX0-0-XXX-0, XX0-0-XXX-0, XX0-0-XXX-0, LT3-2-AIO-3 and LT3-3-AIO-3 Interests. For tax purposes, the interest rate cap contract shall be deemed to have a value of zero.

(n)

Notwithstanding the priority and sources of payments set forth in Article 5 hereof or otherwise, the Securities Administrator 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 REMIC 4. In no event shall any payments provided for in Section 10.01(l) or (m) 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.

Neither the Depositor, the Master Servicer nor 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 the Trustee and any NIMS Insurer has received an Opinion of Counsel addressed to the Trustee (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 or the Securities Administrator, as applicable, of its duties and obligations set forth herein, the Trustee or the Securities Administrator, as applicable, shall indemnify any NIMS Insurer, 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 neither the Trustee nor the Securities Administrator shall be liable for any such Losses attributable to the action or inaction of the Master Servicer, the Depositor, the Class X Certificateholder, the Holder of such Residual Certificate or the Securities Administrator (with regard to the Trustee), as applicable, nor for any such Losses resulting from misinformation provided by the Holder of such Residual Certificate on which the Securities Administrator 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 or the Securities Administrator, as applicable, 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 or the Securities Administrator, as applicable, 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). In addition, neither the Trustee nor the Securities Administrator shall have any liability for the actions or failure to act of the other.

Section 10.04

REO Property.

(a)

Notwithstanding any other provision of this Agreement, the Master Servicer, acting on behalf of the Trustee hereunder, shall not, except to the extent provided in the applicable Servicing Agreement, 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 and any NIMS Insurer 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 the extent provided in its Servicing Agreement) 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 Trustee, or the Master Servicer, acting on its behalf hereunder, shall, or shall cause the applicable Servicer to, continue to attempt to sell the REO Property for its fair market value for such period longer than three years as such extension permits (the “Extended Period”). If the Trustee has not received such an extension and the 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.

Section 11.02

Entire Agreement.

The express terms hereof control and supersede any course of performance and/or usage of the trade inconsistent with any of the terms hereof.

(a)

This Agreement may be amended from time to time by the Depositor, the Master Servicer, the Securities Administrator, and the Trustee, with the consent of any NIMS Insurer, but without the consent of the Credit Risk Manager except to the extent that the rights or obligations of the Credit Risk Manager hereunder are directly affected thereby, 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. Prior to entering into any amendment without the consent of Holders pursuant to this paragraph, the Trustee and any NIMS Insurer shall be provided with an Opinion of Counsel addressed to the Trustee and any NIMS Insurer (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.

This Agreement may also be amended from time to time by the Depositor, the Master Servicer, the Securities Administrator and the Trustee, with the consent of any NIMS Insurer, but without the consent of the Credit Risk Manager except to the extent that the rights or obligations of the Credit Risk Manager hereunder are directly affected thereby and 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 and any NIMS Insurer receives an Opinion of Counsel addressed to the Trustee and the NIMS Insurer, 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 Class Notional Amount (or Percentage Interest) of Certificates of each Class, the Holders of which are required to consent to any such amendment without the consent of the Holders of 100% of the Class Principal Amount or Class Notional Amount (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, any NIMS Insurer 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.

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 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 any NIMS Insurer and the Master Servicer to such transfer;

(ii)

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

Such successor servicer must satisfy the seller/servicer eligibility standards in the Servicing Agreement, exclusive of any experience in mortgage loan origination;

Such successor servicer must execute and deliver to the Trustee an agreement, in form and substance reasonably satisfactory to the Trustee, that contains an assumption by such successor servicer of the due and punctual performance and observance of each covenant and condition to be performed and observed by the applicable Servicer under the applicable Servicing Agreement or, in the case of a transfer of servicing to a party that is already a Servicer pursuant to this Agreement, an agreement to add the related Mortgage Loans to the Servicing Agreement already in effect with such Servicer;

(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 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; and

(vi)

The Seller shall, at its cost and expense, take such steps, or cause the terminated Servicer to take such steps, as may be necessary or appropriate to effectuate and evidence the transfer of the servicing of the Mortgage Loans to such successor servicer, including, but not limited to, the following: (A) to the extent required by the terms of the Mortgage Loans and by applicable federal and state laws and regulations, the Seller shall cause the prior Servicer to timely mail to each obligor under a Mortgage Loan any required notices or disclosures describing the transfer of servicing of the Mortgage Loans to the successor servicer; (B) prior to the effective date of such transfer of servicing, the 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 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 servicer, or, if such transfer occurs after a Servicer Remittance Date but before the next succeeding Deposit 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 servicer, continue to forward to such successor servicer, within one Business Day of receipt, the amount of any payments or other recoveries received by the prior Servicer, and to notify the successor servicer of the source and proper application of each such payment or recovery; and (F) the Seller shall cause the prior Servicer to, after the effective date of transfer of servicing to the successor servicer, continue to cooperate with the successor servicer to facilitate such transfer in such manner and to such extent as the successor servicer may reasonably request. 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 (which includes the Placement Agent) we will do so only (A) to the Depositor, (B) to “qualified institutional buyers” (within the meaning of Rule 144A under the Securities Act) in accordance with Rule 144A under the Securities Act (“QIBs”), (C) pursuant to the exemption from registration provided by Rule 144 under the Securities Act, or (D) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act that is not a QIB (an “Institutional Accredited Investor”) which, prior to such transfer, delivers to the Trustee under the Trust Agreement dated as of August 1, 2003 by and among the Depositor, Aurora Loan Services Inc., as Master Servicer, LaSalle Bank National Association, as Trustee (the “Trustee”), Xxxxx Fargo Bank Minnesota, National Association, as Securities Administrator, and The Murrayhill Company, as Credit Risk Manager, 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 understand that, in connection with any proposed resale of any Privately Offered Certificates to an Institutional Accredited Investor, we will be required to furnish to the Trustee and the Depositor a certification from such transferee in the form hereof to confirm that the proposed sale is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. We further understand that the Privately Offered Certificates purchased by us will bear a legend to the foregoing effect.

(3)

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

(4)

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