Schedule A

Mortgage Loan Schedule (by Mortgage Pool)

This TRUST AGREEMENT, dated as of June 1, 2006 (the “Agreement”), is by and among STRUCTURED ASSET SECURITIES CORPORATION, a Delaware corporation, as depositor (the “Depositor”), U.S. BANK NATIONAL ASSOCIATION, as trustee (the “Trustee”), WELLS FARGO BANK, N.A., a national banking association, as master servicer (in such capacity, the “Master Servicer”) and as securities administrator (in such capacity, the “Securities Administrator”).

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. The Depositor, the Trustee, the Master Servicer and the Securities Administrator 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 be treated for federal income tax purposes as comprising three real estate mortgage investment conduits (each a “REMIC” or, in the alternative, REMIC I, REMIC II and REMIC III (the “Upper Tier REMIC”). Each Certificate, other than the Class LT-R or Class R Certificate, represents ownership of one or more regular interests in REMIC III for purposes of the REMIC Provisions. The Class LT-R Certificate represents ownership of the sole class of residual interest in REMIC I for purposes of the REMIC Provisions. The Class R Certificate represents ownership of the sole class of residual interest in REMIC II 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 II, other than the Class R-2 Interest, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC II for purposes of the REMIC Provisions. REMIC II shall hold as its assets the several Classes of uncertificated Lower Tier Interests in REMIC I, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC I. REMIC I shall hold as its assets the property of the Trust Fund other than the Lower Tier Interests in REMIC I and REMIC II.

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.

REMIC I:

REMIC I shall issue one uncertificated interest in respect of each Mortgage Loan held by the Trust on the Closing Date, each of which is hereby designated as a regular interest in REMIC I (the “REMIC I Regular Interests”). REMIC I shall also issue the Class LT-R Certificate, which shall represent the sole class of residual interest in REMIC I. Each REMIC I Regular Interest shall have an initial principal balance equal to the Scheduled Principal Balance of the Mortgage Loan to which it relates and shall bear interest at a per annum rate equal to the Net Mortgage Rate of such Mortgage Loan. In the event a Qualified Substitute Mortgage Loan is substituted for such Mortgage Loan (the “Original Mortgage Loan”), no amount of interest payable on such Qualified Substitute Mortgage Loan shall be distributed on such REMIC I Regular Interest at a rate in excess of the Net Mortgage Rate of the Original Mortgage Loan.

On each Distribution Date, the Securities Administrator shall first pay or charge as an expense of REMIC I all expenses of the Trust for such Distribution Date. On each Distribution Date the Trustee shall distribute the interest portion of the Available Distribution Amount (net of expenses described in the preceding paragraph) with respect to each of the Lower Tier Interests in REMIC I based on the above-described interest rates.

On each Distribution Date, the Trustee shall distribute the principal portion of the Available Distribution Amount among the Lower Tier Interests in REMIC I in accordance with the amount of the principal attributable to the Mortgage Loan corresponding to each such Lower Tier Interests in REMIC I. All losses on the Mortgage Loans shall be allocated among the Lower Tier Interests in REMIC I in the same manner that principal distributions are allocated.

On each Distribution Date, the Trustee shall first pay or charge as an expense of REMIC I all expenses of the Trust Fund for such Distribution Date.

REMIC II:

REMIC II shall hold as assets the REMIC I Regular Interests. REMIC II shall issue the several classes of uncertificated REMIC II Interests set out below. Each such REMIC II Interest, other than the Class R-2 Interest, is hereby designated as a regular interest in REMIC II. The following table specifies the Class designation, interest rate, and principal amount for each Class of REMIC II Interests:

(8)

(6)

Finally, from the remaining Available Distribution Amount from each of the Collateral Groups to each REMIC II Interest for which there is a Corresponding Class of Certificates (other than the Class LTII-AP and Class LTII-AX Interests) until the principal balance of such REMIC II Interest equals the Class Principal Amount of the Corresponding Class of Certificates immediately after such Distribution Date.

For each Distribution Date, Realized Losses, other than Excess Losses, shall be allocated among the REMIC II Interests in the same manner that principal is allocated among the REMIC II Interests.

Concurrently with the execution and delivery of this Agreement, the Depositor does hereby assign to the Trustee all of its rights and interest under the Mortgage Loan Sale Agreement, including any rights of the Seller under the Servicing Agreement and the Transfer Agreement, but only to the extent assigned under the Mortgage Loan Sale Agreement. The Trustee hereby accepts such assignment, and shall be entitled to exercise all the rights of the Depositor under the Mortgage Loan Sale Agreement as if, for such purpose, it were the Depositor.

It is agreed and understood by the Depositor and the Trustee (and the Seller has so represented and recognized in the Mortgage Loan Sale Agreement) that it is not intended that any Mortgage Loan to be included in the Trust Fund be (i) a “High-Cost Home Loan” as defined in the New Jersey Home Ownership Act effective November 27, 2003, (ii) a “High-Cost Home Loan” as defined in the New Mexico Home Loan Protection Act effective January 1, 2004, (iii) a “High-Cost Home Mortgage Loan” as defined in the Massachusetts Predatory Home Loan Practices Act effective November 7, 2004 or (iv) a “High Cost Home Loan” as defined in the Indiana Home Loan Practices Act effective January 1, 2005.

The foregoing sale, transfer, assignment, set-over, deposit and conveyance does not and is not intended to result in the creation or assumption by the Trustee of any obligation of the Depositor, the Seller or any other Person in connection with the Mortgage Loans.

The Depositor shall have the right to receive any and all loan-level information regarding the characteristics and performance of the Mortgage Loans upon request, and to publish, disseminate or otherwise utilize such information in its discretion, subject to applicable laws and regulations.

(c)

(i) Assignments of Mortgage with respect to each Non-MERS Mortgage Loan other than a Cooperative Loan shall be recorded; provided, however, that such Assignments need not be recorded if, on or prior to the Closing Date, the Depositor delivers, at its own expense, an Opinion of Counsel addressed to the Trustee (which must be Independent counsel) acceptable to the Trustee and the Rating Agencies, to the effect that recording in such states is not required to protect the Trustee’s interest in the related Non-MERS Mortgage Loans; provided, further, that notwithstanding the delivery of any Opinion of Counsel, the Master Servicer shall direct the Servicer to submit each Assignment of Mortgage for recording upon the occurrence of a bankruptcy, insolvency or foreclosure relating to the Mortgagor under the related Mortgage. Subject to the preceding sentence, as soon as practicable after the Closing Date (but in no event more than three months thereafter except to the extent delays are caused by the applicable recording office), the Master Servicer, at the expense of the Depositor and with the cooperation of the Servicer, shall direct to be properly recorded by the Servicer in each public recording office where the related Mortgages are recorded each Assignment of Mortgage referred to in subsection (b)(v) above with respect to each Non-MERS Mortgage Loan.

With respect to each Cooperative Loan, the Master Servicer, at the expense of the Depositor and with the cooperation of the Servicer, shall direct such Servicer to take such actions as are necessary under applicable law in order to perfect the interest of the Trustee in the related Mortgaged Property.

(d)

For Mortgage Loans (if any) that have been prepaid in full after the Cut-off Date and prior to the Closing Date, the Depositor, in lieu of delivering the above documents, herewith delivers to the Trustee, or to the Custodian on behalf of the Trustee, an Officer’s Certificate which shall include a statement to the effect that all amounts received in connection with such prepayment that are required to be deposited in the Certificate Account pursuant to Section 4.01 have been so deposited. All original documents that are not delivered to the Trustee or the Custodian on behalf of the Trustee shall be held by the Master Servicer or the Servicer in trust for the benefit of the Trustee and the Certificateholders.

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 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 Custodian on behalf of the Trustee, under this Section 2.02. The Trustee, or the Custodian on behalf of the Trustee, will execute and deliver to the Depositor, the Master Servicer and the Trustee on the Closing Date an Initial Certification in the form annexed hereto as Exhibit B-1 (or in the form annexed to the Custodial Agreement as Exhibit B-1, as applicable).

(b)

Within 45 days after the Closing Date, the Trustee or the Custodian on behalf of the Trustee, will, for the benefit of Holders of the Certificates, review each Mortgage File to ascertain that all required documents set forth in Section 2.01 have been received and appear on their face to contain the requisite signatures by or on behalf of the respective parties thereto, and shall deliver to the Trustee, the Depositor and the Master Servicer an Interim Certification in the form annexed hereto as Exhibit B-2 (or in the form annexed to the 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 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 the 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 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 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. Within 90 days of its receipt of such notice, the Transferor, or, if the Transferor does not do so, the Depositor shall be required to cure such Material Defect (and, in such event, the Depositor shall provide the Trustee with an Officer’s Certificate confirming that such cure has been effected). If the 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 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 Custodian, shall deliver to the Trustee, the Depositor and the Master Servicer a Final Certification substantially in the form attached as Exhibit B-3 (or in the form annexed to the Custodial Agreement as Exhibit B-3, as applicable) evidencing the completeness of the Mortgage Files in its possession or control, with any exceptions noted thereto.

(e)

Nothing in this Agreement shall be construed to constitute an assumption by the Trust Fund, the Trustee, the 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 functions of the Trustee with respect to the custody, acceptance, inspection, receipt and release of the Mortgage Files pursuant to Sections 2.01, 2.02, 2.05 and 9.19 and preparation and delivery of the acknowledgements of receipt and certifications required under such sections shall be performed by the Custodian pursuant to the terms of the Custodial Agreement. The Trustee is hereby authorized and directed by the Depositor to appoint the Custodian and to execute and deliver 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, and the Servicing Agreement. The Depositor hereby directs the Trustee, solely in its capacity as Trustee hereunder, to execute and deliver, concurrently with the execution and delivery of this Agreement, and the Servicing Agreement to which the Trustee is a party.

Representations and Warranties of the Depositor.

(a)

The Depositor hereby represents and warrants to the Trustee, for the benefit of Certificateholders, the Master Servicer and the Securities Administrator 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 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 the Transferor with respect to the related Mortgage Loans in the Transfer Agreement, which have been assigned to the Trustee hereunder, were made as of the date specified in the 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 Transferor under the Transfer Agreement and (ii) a representation or warranty of the Seller under the Mortgage Loan Sale Agreement, the only right or remedy of the Trustee or any Certificateholder hereunder shall be their rights to enforce the obligations of the 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 Transferor in the 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 the Transferor and of the 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 the Transferor or the Seller and assigned to the Trustee, the Depositor, the 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 (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 the Transferor assigned to the Trustee, the Trustee shall enforce its rights under the Transfer Agreement and the Mortgage Loan Sale Agreement for the benefit of Certificateholders. As provided in the Mortgage Loan Sale Agreement, if the Transferor substitutes a mortgage loan for a Deleted Mortgage Loan pursuant to the Transfer Agreement and such substitute mortgage loan is not a Qualifying Substitute Mortgage Loan, then pursuant to the terms of the Mortgage Loan Sale Agreement the Seller will, in exchange for such substitute mortgage loan, (i) pay to the Trust Fund the applicable Purchase Price for the affected Mortgage Loan or (ii) within two years of the Closing Date, substitute a Qualifying Substitute Mortgage Loan.

Section 2.05

Repurchase, Purchase or Substitution of Mortgage Loans.

(a)

With respect to any Mortgage Loan repurchased by the Depositor pursuant to this Agreement, by the Seller pursuant to the Mortgage Loan Sale Agreement or by the Transferor pursuant to the Transfer Agreement, the principal portion of the funds received by the Securities Administrator in respect of such repurchase of a Mortgage Loan will be considered a Principal Prepayment and shall be deposited in the Certificate Account or a Custodial Account, as applicable. The Trustee (i) upon receipt by the Securities Administrator of the full amount of the Purchase Price for a Deleted Mortgage Loan, (ii) upon receipt of a written certification from the Master Servicer that it has received the full amount of the Purchase Price for a Deleted Mortgage Loan and has deposited such amount in the Certificate Account or (iii) upon receipt of notification from the Custodian that it had received the Mortgage File for a Qualifying Substitute Mortgage Loan substituted for a Deleted Mortgage Loan (and any applicable Substitution Amount), shall release or cause to be released and reassign to the Depositor, the Seller or the Transferor, as applicable, the related Mortgage File for the Deleted Mortgage Loan and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty, as shall be necessary to vest in such party or its designee or assignee title to any Deleted Mortgage Loan released pursuant hereto, free and clear of all security interests, liens and other encumbrances created by this Agreement, which instruments shall be prepared by the 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 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 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 the Custodian) pursuant to the terms of this Article II in exchange for a Deleted Mortgage Loan: (i) the Depositor, the Transferor or the Seller, as applicable, must deliver to the Trustee (or the 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 Master Servicer, at the expense of the Depositor and at the direction and with the cooperation of the 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 Servicer if required pursuant to Section 2.01(c), or (ii) with respect to a Qualifying Substitute Mortgage Loan that is a MERS Mortgage Loan, cause to be taken such actions as are necessary to cause the Trustee to be clearly identified as the owner of each such Mortgage Loan on the records of MERS if required pursuant to Section 2.01(c).

(c)

Notwithstanding any other provision of this Agreement, the right to substitute Mortgage Loans pursuant to this Article II shall be subject to the additional limitations that no substitution of a Qualifying Substitute Mortgage Loan for a Deleted Mortgage Loan shall be made unless the Trustee has received an Opinion of Counsel 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 (or the aggregate principal balance of the Lower Tier REMIC I Uncertificated Regular Interests, if applicable) in all of the Depositor’s right, title and interest in, to and under, whether now owned or hereafter acquired, the Trust Fund; (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 or Lower Tier REMIC I Uncertificated Regular Interests, as applicable, 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 and the Securities Administrator. 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 intermediate 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 intermediate transferee to file in any filing office any initial financing statements, any amendments to financing statements, any continuation statements, or any other statements or filings described in this paragraph (b).

ARTICLE III

THE CERTIFICATES

Section 3.01

The Certificates.

(a)

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

(b)

The Certificates shall be executed by manual or facsimile signature on behalf of the Securities Administrator by an authorized officer. Each Certificate shall, on original issue, be authenticated by the Securities Administrator upon the order of the Depositor upon receipt by the Trustee (or its Custodian) 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 Securities Administrator 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 Securities Administrator or the Authenticating Agent for authentication and the Securities Administrator or the Authenticating Agent shall authenticate and deliver such Certificates as in this Agreement provided and not otherwise.

(c)

The Privately Offered Certificates offered and sold in reliance on the exemption from registration under Rule 144A under the Securities Act shall be issued initially in the form of one or more permanent global Certificates in definitive, fully registered form without interest coupons with the applicable legends set forth in Exhibit A added to the forms of such Certificates (each, a “Restricted Global Security”), which shall be deposited on behalf of the subscribers for such Certificates represented thereby with the Securities Administrator, as custodian for The Depository Trust Company (“DTC”) and registered in the name of a nominee of DTC, duly executed and authenticated by the Securities Administrator as hereinafter provided. The aggregate principal amounts of the Restricted Global Securities may from time to time be increased or decreased by adjustments made on the records of the Securities Administrator or DTC or its nominee, as the case may be, as hereinafter provided.

(d)

The Privately Offered Certificates sold in offshore transactions in reliance on Regulation S shall be issued initially in the form of one or more permanent global Certificates in definitive, fully registered form without interest coupons with the applicable legends set forth in Exhibit A hereto added to the forms of such Certificates (each, a “Regulation S Global Security”), which shall be deposited on behalf of the subscribers for such Certificates represented thereby with the Securities Administrator, as custodian for DTC and registered in the name of a nominee of DTC, duly executed and authenticated by the Securities Administrator as hereinafter provided. The aggregate principal amounts of the Regulation S Global Securities may from time to time be increased or decreased by adjustments made on the records of the Securities Administrator or DTC or its nominee, as the case may be, as hereinafter provided.

(e)

The Privately Offered Certificates sold to an “accredited investor” under Rule 501(a)(1), (2), (3) or (7) under the Securities Act shall be issued initially in the form of one or more Definitive Certificates.

Section 3.02

Registration.

The Securities Administrator is hereby appointed, and hereby accepts its appointment as, Certificate Registrar in respect of the Certificates (and, after a Section 7.01(c) Purchase Event, the Lower Tier REMIC I Uncertificated Regular Interests) and shall maintain books for the registration and for the transfer of Certificates (and, after a Section 7.01(c) Purchase Event, the Lower Tier REMIC I Uncertificated Regular Interests) (the “Certificate Register”). The Securities Administrator may appoint a bank or trust company to act as Certificate Registrar. A registration book shall be maintained for the Certificates (and Lower Tier REMIC I Uncertificated Regular Interests, as the case may be) 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 Securities Administrator and the appointment of a successor Securities Administrator. The Certificate Registrar may appoint, by a written instrument delivered to the Holders and the Master Servicer, any bank or trust company to act as co-registrar under such conditions as the Certificate Registrar may prescribe; provided, however, that the Certificate Registrar shall not be relieved of any of its duties or responsibilities hereunder by reason of such appointment.

Upon the occurrence of a Section 7.01(c) Purchase Event, the Master Servicer shall provide the Securities Administrator with written notice of the identity of any transferee of the Master Servicer’s interest in the Lower Tier REMIC I Uncertificated Regular Interests, which notice shall contain a certification that such transferee is a permitted LTURI-holder hereunder. The Lower Tier REMIC I Uncertificated Regular Interests may only be transferred in whole and not in part to no more than one LTURI-holder at a time who is either (1) an affiliate of the Master Servicer or (2) a trustee of a privately placed securitization. The Securities Administrator and the Depositor shall treat the Person in whose name the Lower Tier REMIC I Uncertificated Regular Interests are registered on the books of the Certificate Registrar as the LTURI-holder for all purposes hereunder.

Section 3.03

Transfer and Exchange of Certificates.

(a)

A Certificate (other than a Book-Entry Certificate 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 Securities Administrator shall execute, and the Securities Administrator 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 or Percentage Interest 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 Securities Administrator shall execute, and the Securities Administrator or the Authenticating Agent shall authenticate, date and deliver the Certificates which the Certificateholder making the exchange is entitled to receive.

(c)

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

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

(i)

The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is (x) to the Depositor or the Placement Agent, an affiliate (as defined in Rule 405 under the Securities Act) 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 by a transferor that has provided the Securities Administrator 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 Securities Act, or to any Person all of the equity owners in which are such accredited investors, by a transferor who furnishes to the Securities Administrator a letter of the transferee substantially in the form of Exhibit G hereto.

(d)

(i) No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate shall be made to any Person unless the Securities Administrator 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 Securities Administrator, 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 Servicer, the Securities Administrator or the Depositor to any obligation in addition to those undertaken in the Agreement; provided, however, that the Securities Administrator 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 Securities Administrator, 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 or the Depositor.

Notwithstanding the foregoing, no opinion or certificate shall be required for the initial issuance of the ERISA-Restricted Certificates. The Securities Administrator 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 Securities Administrator 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 Securities Administrator in accordance with the foregoing requirements. The Securities Administrator 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 Securities Administrator shall be paid and delivered by the Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Securities Administrator an affidavit in substantially the form attached hereto as Exhibit D-2. In addition, the Securities Administrator 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 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 Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Securities Administrator 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)

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

(A)

Subject to clauses (B) and (C) of this Section 3.03(h), transfers of a Global Security representing any Privately Offered Certificate shall be limited to transfers of such Global Security, in whole or in part, to nominees of DTC or to a successor of DTC or such successor’s nominee.

(B)

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

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

(D)

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

Upon the issuance of any new Certificate under this Section 3.05, the Securities Administrator 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 Securities Administrator 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 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 nor any agent of any of them shall be affected by notice to the contrary.

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 Securities Administrator without charge to the Holder. Upon surrender for cancellation of any one or more temporary Certificates, the Securities Administrator 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.

(a)

The Securities Administrator may appoint a Paying Agent (which may be the Securities Administrator) for the purpose of making distributions to Certificateholders hereunder. The Securities Administrator shall cause such Paying Agent (if other than the Securities Administrator) to execute and deliver to the Securities Administrator an instrument in which such Paying Agent shall agree with the Securities Administrator 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 Securities Administrator 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 Securities Administrator. If the Paying Agent is not the Securities Administrator, the Securities Administrator 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.

(b)

Any Paying Agent (other than the Securities Administrator) shall comply with its reporting obligations under Regulation AB with respect to the Trust Fund in form and substance similar to those of the Securities Administrator pursuant to Section 6.20, and the related assessment of compliance shall cover, at a minimum, the elements of the servicing criteria applicable to the Paying Agent indicated in Exhibit S attached hereto. The Paying Agent shall give prior written notice to the Sponsor, the Master Servicer and the Depositor of the appointment of any Subcontractor by it and a written description (in form and substance satisfactory to the Sponsor and the Depositor) of the role and function of each Subcontractor utilized by the Paying Agent, as applicable, specifying (A) the identity of each such Subcontractor and (B) which elements of the servicing criteria set forth under Item 1122(d) of Regulation AB will be addressed in assessments of compliance provided by each such Subcontractor. In addition, the Paying Agent shall notify the Sponsor, the Master Servicer and the Depositor within five (5) calendar days of knowledge thereof (i) of any legal proceedings pending against the Paying Agent of the type described in Item 1117 (§ 229.1117) of Regulation AB, (ii) any merger, consolidation or sale of substantially all of the assets of the Paying Agent and (iii) if the Paying Agent shall become (but only to the extent not previously disclosed) at any time an affiliate of any of the parties listed on Exhibit V hereto or any of their affiliates.

(c)

Any Paying Agent agrees to indemnify the Depositor, the Trustee, the Securities Administrator and the Master Servicer, and each of their respective directors, officers, employees and agents and the Trust Fund and hold each of them harmless from and against any losses, damages, penalties, fines, forfeitures, legal fees and expenses and related costs, judgments, and any other costs, fees and expenses that any of them may sustain arising out of or based upon the failure by such Paying Agent to deliver any information, report or certification when and as required under Section 6.20 and Section 9.25(a). This indemnification shall survive the termination of this Agreement or the termination of such Paying Agent hereunder.

Section 3.09

Book-Entry Certificates.

(a)

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

(i)

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

(ii)

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

(iii)

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

(iv)

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

(b)

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

(c)

If (i) (A) the Depositor advises the Securities Administrator in writing that the Clearing Agency is no longer willing or able to discharge properly its responsibilities with respect to the Book-Entry Certificates, and (B) the Depositor is unable to locate a qualified successor or (ii) after the occurrence of an Event of Default, Certificate Owners representing beneficial interests aggregating not less than 50% of the Class Principal Amount of a Class of Book-Entry Certificates identified as such to the Securities Administrator by an Officer’s Certificate from the Clearing Agency advise the Securities Administrator and the Clearing Agency through the Clearing Agency Participants in writing that the continuation of a book-entry system through the Clearing Agency is no longer in the best interests of the Certificate Owners of a Class of Book-Entry Certificates, the Securities Administrator shall notify or cause the Certificate Registrar to notify the Clearing Agency to effect notification to all Certificate Owners, through the Clearing Agency, of the occurrence of any such event and of the availability of Definitive Certificates to Certificate Owners requesting the same. Upon surrender to the Securities Administrator of the Book-Entry Certificates by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration, the Securities Administrator shall issue the Definitive Certificates. Neither the Depositor nor the Securities Administrator shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Clearing Agency shall be deemed to be imposed upon and performed by the Securities Administrator, to the extent applicable, with respect to such Definitive Certificates and the Securities Administrator shall recognize the holders of the Definitive Certificates as Certificateholders hereunder. Notwithstanding the foregoing, the Securities Administrator, upon the instruction of the Depositor, shall have the right to issue Definitive Certificates on the Closing Date in connection with credit enhancement programs.

On the Closing Date, the Securities Administrator shall open and shall thereafter maintain a segregated account held in trust (the “Certificate Account”), entitled “Certificate Account, Wells Fargo Bank, N.A., as Securities Administrator, in trust for the benefit of the Holders of TBW Mortgage-Backed Trust Mortgage Pass-Through Certificates, Series 2006-3.” The Certificate Account shall relate solely to the Certificates and to the Lower Tier REMIC I Uncertificated Regular Interests issued by the Trust Fund hereunder, and funds in such Certificate Account shall not be commingled with any other monies.

(b)

The Certificate Account shall be an Eligible Account. If an existing Certificate Account ceases to be an Eligible Account, the Securities Administrator shall establish a new Certificate Account that is an Eligible Account within 10 days and transfer all funds and investment property on deposit in such existing Certificate Account into such new Certificate Account.

(c)

The Securities Administrator shall give to the Trustee prior written notice of the name and address of the depository institution at which the Certificate Account is maintained and the account number of such Certificate Account. The Securities Administrator shall take such actions as are necessary to cause the depository institution holding the Certificate Account to hold such account in the name of the Securities Administrator under this Agreement.

(d)

The Master Servicer shall deposit or cause to be deposited into the Certificate Account, no later than the second Business Day following the Closing Date, any amounts received with respect to the Mortgage Loans representing Scheduled Payments on the Mortgage Loans due after the Cut-off Date and unscheduled payments received on or after the Cut-off Date and on or before the Closing Date. Thereafter, the Master Servicer shall deposit or cause to be deposited in the Certificate Account on the earlier of the Servicer Remittance Date and two Business Days 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, any Subsequent Recovery and any Scheduled Payment attributable to principal received after its related Due Date, 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 Certificate Account in accordance with Section 5.04;

(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 Certificate Account in accordance with Section 5.04) and (y) any amounts reimbursable to the Servicer with respect to such Mortgage Loan under the Servicing Agreement and retained by the Servicer;

(iv)

(e)

Funds in the Certificate Account for the period from the Servicer Remittance Date to and including one Business Day immediately preceding the related Distribution Date (the “Investment Period”) shall be invested in Eligible Investments selected by and at the written direction of the Securities Administrator, which shall mature not later than one Business Day prior to the Distribution Date and any such Eligible Investment shall not be sold or disposed of prior to its maturity. In the absence of written instructions regarding the investment of any such funds on deposit in the Certificate Account, such funds shall be invested in the Wells Fargo Advantage Prime Money Market Fund. All such Eligible Investments shall be made in the name of the Securities Administrator in trust for the benefit of the Trustee and Holders of the TBW Mortgage-Backed Trust Mortgage Pass-Through Certificates, Series 2006-3. An amount representing the investment income over five Business Days on such Eligible Investments shall be payable to the Securities Administrator as its compensation hereunder (out of which the Securities Administrator shall pay the Master Servicing Fee and Trustee Fee to the Master Servicer and Trustee, respectively). Any remaining funds for each Investment Period shall be payable to the Servicer as additional servicing compensation. The amount of any losses incurred in respect of any such investments during the Investment Period shall be deposited in such Certificate Account by the Securities Administrator out of its own funds, without any right of reimbursement therefor, immediately as realized. The foregoing requirements for deposit in the Certificate Account are exclusive, it being understood and agreed that, without limiting the generality of the foregoing, (i) payments of interest on funds in the Certificate Account need not be deposited by the Master Servicer in the Certificate Account and may be retained by the Master Servicer for payment to the Securities Administrator or remitted directly to the Servicer, as applicable, and (ii) payments in the nature of late payment charges, assumption fees and other incidental fees and charges relating to the Mortgage Loans need not be deposited by the Master Servicer in the Certificate Account and may be retained by the Master Servicer for payment to the Servicer as additional servicing compensation. If the Master Servicer deposits in the Certificate Account any amount not required to be deposited therein, it may at any time withdraw such amount from such Certificate Account.

Section 4.02

Application of Funds in the Certificate Account.

The Master Servicer (or if applicable, the Securities Administrator), may, from time to time, make, or cause to be made, withdrawals from the Certificate Account for the following purposes:

(i)

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

(ii)

to reimburse itself or the Servicer, following a final liquidation of a Mortgage Loan (except as otherwise provided in the Servicing Agreement) for any previously unreimbursed Advances or Servicing Advances made by it or by such Servicer (A) that it determines in good faith will not be recoverable from amounts representing late recoveries of payments of principal or interest respecting the particular Mortgage Loan as to which such Advance or Servicing Advance was made or from Liquidation Proceeds or Insurance Proceeds with respect to such Mortgage Loan and/or (B) to the extent that such unreimbursed Advances or Servicing Advances exceed the related Liquidation Proceeds or Insurance Proceeds, it being understood, in the case of each such reimbursement, that such Master Servicer's or Servicer's right thereto shall be prior to the rights of the Certificateholders;

(iii)

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

(iv)

to reimburse itself or the Servicer for expenses incurred by and recoverable by or reimbursable to it or the Servicer pursuant to this Agreement, including, without limitation, Sections 9.04, 9.06(b), 9.07(a), 9.30 or 11.15;

(v)

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

(vi)

to make payment to the Trustee pursuant to any provision of this Agreement or to reimburse the Trustee for any fees or expenses reimbursable to it pursuant to Section 6.12;

(vii)

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

(viii)

to make distributions to Certificateholders pursuant to Article V;

(ix)

to make payment to itself, the Securities Administrator, the Trustee and others pursuant to any provision of this Agreement;

(x)

to withdraw funds deposited in error in the Certificate Account;

(xi)

to clear and terminate the Certificate Account pursuant to Section 7.02;

(xii)

to pay to the Seller any income and gain realized on the Certificate Account from any Eligible Investment other than during the Master Servicer Investment Period in accordance with Section 4.01(e) hereto; and

(xiii)

to pay to the Seller any amounts received in respect of Prepayment Premiums; and

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

(d)

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

(e)

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

If the Servicer fails to remit Advances required to be made under the Servicing Agreement, the Master Servicer shall itself make, or shall cause the successor servicer to make, such Advance not later than the Business Day immediately preceding the related Distribution Date. If the Master Servicer determines that an Advance is required, it shall not later than the Business Day immediately preceding the related Distribution Date deposit in the Certificate Account from its own funds (or funds advanced by the Servicer) immediately available funds in an amount equal to such Advance. The Master Servicer and the Servicer shall be entitled to be reimbursed from the Certificate Account for all Advances made by it as provided in Section 4.02.

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

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

(c)

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them.

In addition, the Trustee shall have no responsibility for any act or omission of the Master Servicer prior to the issuance of any notice of termination. The Trustee shall have no liability relating to the representations and warranties of the Master Servicer set forth in Section 9.14. The Trustee shall not be obligated to perform any obligation of the Master Servicer under Sections 6.20, 9.25 or 9.26 with respect to any period of time during which the Trustee was not acting as the Master Servicer. In the Trustee’s capacity as such successor, the Trustee shall have the same limitations on liability herein granted to the Master Servicer. As compensation therefor, the Trustee shall be entitled to receive all compensation payable to the Master Servicer under this Agreement, including the Master Servicing Fee.

(c)

Notwithstanding the above, the Trustee may, if it shall be unwilling to continue to so act, or shall, if it is unable to so act, petition a court of competent jurisdiction to appoint, or appoint on its own behalf any established housing and home finance institution servicer, master servicer, servicing or mortgage servicing institution having a net worth of not less than $15,000,000 and meeting such other standards for a successor master servicer as are set forth in this Agreement, as the successor to such Master Servicer in the assumption of all of the responsibilities, duties or liabilities of the Master Servicer hereunder. Any entity designated by the Trustee as a successor master servicer may be an Affiliate of the Trustee; provided, however, that, unless such Affiliate meets the net worth requirements and other standards set forth herein for a successor master servicer, the Trustee, in its individual capacity shall agree, at the time of such designation, to be and remain liable to the Trust Fund for such Affiliate’s actions and omissions in performing its duties hereunder. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted to the Master Servicer hereunder. The Trustee and such successor shall take such actions, consistent with this Agreement, as shall be necessary to effectuate any such succession and may make other arrangements with respect to the servicing to be conducted hereunder which are not inconsistent herewith. The Master Servicer shall cooperate with the Trustee and any successor master servicer in effecting the termination of the Master Servicer’s responsibilities and rights hereunder including, without limitation, notifying Mortgagors of the assignment of the master servicing functions and providing the Trustee and successor master servicer, as applicable, all documents and records in electronic or other form reasonably requested by it to enable it to assume the Master Servicer’s functions hereunder and the transfer to the Trustee or such successor master servicer, as applicable, all amounts which shall at the time be or should have been deposited by the Master Servicer in the Certificate Account and any other account or fund maintained with respect to the Certificates or the Lower Tier REMIC I Uncertificated Regular Interests or thereafter be received with respect to the Mortgage Loans. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (i) the failure of the Master Servicer to deliver, or any delay in delivering, cash, documents or records to it, (ii) the failure of the Master Servicer to cooperate as required by this Agreement, (iii) the failure of the Master Servicer to deliver the Mortgage Loan data to the Securities Administrator as required by this Agreement or (iv) restrictions imposed by any regulatory authority having jurisdiction over the Master Servicer. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by the failure of the Securities Administrator to deliver, or any delay in delivering cash, documents or records to it.

Section 6.15

Additional Remedies of Trustee Upon Event of Default.

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

Section 6.16

Waiver of Defaults.

More than 50% of the Aggregate Voting Interests of Certificateholders may waive any default or Event of Default by the Master Servicer in the performance of its obligations hereunder, except that a default in the making of any required deposit to the Certificate Account that would result in a failure of the Securities Administrator to make any required payment of principal of or interest on the Certificates may only be waived with the consent of 100% of the affected Certificateholders. Upon any such waiver of a past default, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived.

Section 6.17

Notification to Holders.

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

Section 6.19

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

In the event that a Responsible Officer of the Trustee 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, the Trustee and the Securities Administrator.

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; Purchase of Lower Tier REMIC I Uncertificated Regular Interests.

(a)

The respective obligations and responsibilities of the Trustee and the Master Servicer created hereby (other than the obligation of the Securities Administrator to make payments to Certificateholders, the obligation of the Master Servicer to make a final remittance to the Securities Administrator pursuant to Section 4.01, and the obligations of the Master Servicer to the Securities Administrator pursuant to Section 9.10 and to the Securities Administrator and the Trustee pursuant to Sections 9.14 and 9.31) 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 (each, a “Trust Fund Termination Event”); 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 Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James’s, living on the date hereof. Upon the occurrence of a Trust Fund Termination Event, each REMIC shall be terminated in a manner that shall qualify as a “qualified liquidation” under the REMIC Provisions.

(b)

On any Distribution Date occurring on or after the Initial Optional Termination Date, the Master Servicer or LTURI-holder, as applicable, with the prior written consent of 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. 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 fair market value of any REO Property and any other property held by any REMIC, such fair market value to be determined by an independent appraiser or appraisers mutually agreed upon by the Master Servicer and the Securities Administrator (reduced, in the case of REO Property, by (1) reasonably anticipated disposition costs and (2) any amount by which the fair market value as so reduced exceeds the outstanding principal balance of the related Mortgage Loan plus interest accrued thereon at the applicable Net Mortgage Rate to the date of such purchase) and (iii) any unreimbursed Servicing Advances. The Master Servicer, the Servicer, the Trustee, the Securities Administrator and the Custodian 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 any such entity under this Agreement, the Servicing Agreement or the Custodial Agreement, together with any accrued and unpaid compensation and any other amounts due to the Master Servicer, the Securities Administrator or the Trustee hereunder or the Servicer or the Custodian.

(c)

On any Distribution Date occurring on or after the Initial Optional Termination Date, the Master Servicer, with the prior written consent of the Seller, which consent shall not be unreasonably withheld, has the option to purchase all of the Lower Tier REMIC I Uncertificated Regular Interests. Upon exercise of such option, the Lower Tier REMIC I Uncertificated Regular Interests shall be sold to the Master Servicer at a price (the “Lower Tier REMIC I Uncertificated Regular Interests Purchase 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 and (ii) the fair market value of any REO Property and any other property held by any REMIC, such fair market value to be determined by an independent appraiser or appraisers mutually agreed upon by the Master Servicer and the Securities Administrator (reduced, in the case of REO Property, by (1) reasonably anticipated disposition costs and (2) any amount by which the fair market value as so reduced exceeds the outstanding principal balance of the related Mortgage Loan plus interest accrued thereon at the applicable Net Mortgage Rate to the date of such purchase). If the Master Servicer elects to exercise such option, each REMIC created pursuant to this Agreement (other than REMIC I) shall be terminated in such a manner so that the termination of each such REMIC shall qualify as a “qualified liquidation” under the REMIC Provisions and the Lower Tier REMIC I Uncertificated Regular Interests and the Class LT-R Certificates will evidence the entire beneficial interest in the property of the Trust Fund. Following a purchase of the Lower Tier REMIC I Uncertificated Regular Interests pursuant to this subsection, the Trust Fund (and REMIC I) will remain outstanding and final payment on the Certificates (other than the Class LT-R Certificates) will be made in accordance with Sections 7.03(a)(iii) and 5.02. The Trust Fund will terminate upon the occurrence of a Trust Fund Termination Event, in accordance with Section 7.01(a).

Section 7.02

Procedure Upon Termination of Trust Fund or Purchase of Lower Tier REMIC I Uncertificated Regular Interests.

(a)

Notice of any Trust Fund Termination Event and notice of the purchase of the Lower Tier REMIC I Uncertificated Regular Interests, specifying the Distribution Date upon which the final distribution to the Certificates (other than the Class LT-R Certificates, in the case of a purchase of the Lower Tier REMIC I Uncertificated Regular Interests) shall be made, shall be given by the Securities Administrator by first class mail to Certificateholders mailed promptly (and in no event later than five Business Days) (x) after the Securities Administrator has received notice from the Master Servicer or the LTURI-holder, as applicable, of its election to cause (1) the sale of all of the property of the Trust Fund pursuant to Section 7.01(b) or (2) the purchase of the Lower Tier REMIC I Uncertificated Regular Interests pursuant to Section 7.01(c), or (y) upon the final payment or other liquidation of the last Mortgage Loan or REO Property in the Trust Fund. In the case of a Trust Fund Termination Event, the Securities Administrator shall also give notice to the Master Servicer, and the Certificate Registrar at the time notice is given to Holders.

In the case of a Trust Fund Termination Event, such notice shall specify (A) the Distribution Date upon which final distribution on the Certificates or Lower Tier REMIC I Uncertificated Regular Interests 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 Securities Administrator therein specified. Upon any such Trust Fund Termination Event, the duties of the Certificate Registrar with respect to the Certificates or Lower Tier REMIC I Uncertificated Regular Interests shall terminate and the Securities Administrator shall terminate the Certificate Account and any other account or fund maintained with respect to the Certificates or Lower Tier REMIC I Uncertificated Regular Interests, subject to the Securities Administrator’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment.

In the case of a purchase of the Lower Tier REMIC I Uncertificated Regular Interests, such notice shall specify (A) the Distribution Date upon which final distribution on the Certificates (other than the Class LT-R Certificates) of all amounts required to be distributed to Certificateholders pursuant to Section 5.02 (other than any distributions to the Class LT-R Certificates in respect of REMIC I) will be made upon presentation and surrender of the Certificates (other than the Class LT-R 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 (other than the Class LT-R Certificates) at the office or agency of the Securities Administrator therein specified. Upon any such purchase of the Lower Tier REMIC I Uncertificated Regular Interests, the duties of the Certificate Registrar with respect to the Certificates other than the Class LT-R Certificate shall terminate but the Securities Administrator shall not terminate the Certificate Account and any other account or fund maintained with respect to the Certificates, subject to the Securities Administrator’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment. For all Distribution Dates following the Distribution Date on which the Master Servicer purchases the Lower Tier REMIC I Uncertificated Regular Interests, all amounts that would be distributed on the Certificates (other than the Class LT-R Certificate and exclusive of amounts payable from any fund held outside of REMIC I) absent such purchase shall be payable to the LTURI-holder.

(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 Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Securities Administrator 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 Securities Administrator in connection with any Trust Fund Termination Event or any purchase of the Lower Tier REMIC I Uncertificated Regular Interests shall be reimbursed from proceeds received from such termination or purchase.

Section 7.03

Additional Trust Fund Termination Event or Purchase of the Lower Tier REMIC I Uncertificated Regular Interests.

(a)

Any termination of the Trust Fund pursuant to Section 7.01(a) or any termination of a REMIC pursuant to Section 7.01(c) shall be effected in accordance with the following additional requirements, unless the Securities Administrator seeks (at the request of the party exercising the option to purchase all of the Mortgage Loans or Lower Tier REMIC I Uncertificated Regular Interests pursuant to Section 7.01(b) or Section 7.01(c), respectively), and subsequently receives, an Opinion of Counsel (at the expense of such requesting party), addressed to the Securities Administrator to the effect that the failure 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 (other than the Class LT-R Certificates, in the case of a purchase of the Lower Tier REMIC I Uncertificated Regular Interests, upon notification by the Master Servicer, the Securities Administrator or an Affiliate of the Seller that it intends to exercise its option to cause the termination of the Trust Fund or purchase the Lower Tier REMIC I Uncertificated Regular Interests, the Securities Administrator shall adopt a plan of complete liquidation on behalf of each REMIC (other than REMIC I, in the case of a purchase of the Lower Tier REMIC I Uncertificated Regular Interests), meeting the requirements of a qualified liquidation under the REMIC Provisions;

(ii)

Any sale of the assets of the Trust Fund or the Lower Tier REMIC I Uncertificated Regular Interests 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 (other than the Class LT-R Certificates, in the case of a purchase of the Lower Tier REMIC I Uncertificated Regular Interests);

(iii)

On the date specified for final payment of the Certificates (other than the Class LT-R Certificates, in the case of a purchase of the Lower Tier REMIC I Uncertificated Regular Interests), the Securities Administrator shall make final distributions of principal and interest on such Certificates. In the case of a Trust Fund Termination Event, and, after payment of, or provision for any outstanding expenses, the Securities Administrator shall distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand after such final payment (other than cash retained to meet claims), and the Trust Fund (and each REMIC) shall terminate at that time; and

(iv)

In no event may the final payment on the Certificates or the final distribution or credit to the Holders of the Residual Certificates in respect of the residual interest in any liquidated REMIC be made after the 89th day from the date on which the plan of complete liquidation for such REMIC is adopted.

(b)

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

(c)

In connection with the termination of the Trust Fund, or a Section 7.01(c) Purchase Event, the Securities Administrator may request an Opinion of Counsel addressed to the Securities Administrator (at the expense of the Depositor) to the effect that all the requirements of a qualified liquidation under the REMIC Provisions have been met.

ARTICLE VIII

RIGHTS OF CERTIFICATEHOLDERS

Section 8.01

Limitation on Rights of Holders.

(a)

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

(b)

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

Section 8.02

Access to List of Holders.

(a)

If the Trustee is not acting as Certificate Registrar, the Certificate Registrar will furnish or cause to be furnished to the Trustee, within fifteen days after receipt by the Certificate Registrar of a request by the Trustee in writing, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Certificateholders of each Class as of the most recent Record Date.

(b)

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

(c)

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

Section 8.03

Acts of Holders of Certificates.

(a)

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

(b)

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

(c)

The ownership of Certificates or Lower Tier REMIC I Uncertificated Regular Interests (whether or not such Certificates or Lower Tier REMIC I Uncertificated Regular Interests shall be overdue and notwithstanding any notation of ownership or other writing thereon made by anyone other than the Trustee) shall be proved by the Certificate Register, and none of the Trustee, the Master Servicer, the Securities Administrator or the Depositor shall be affected by any notice to the contrary.

(d)

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

ARTICLE IX

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

Section 9.01

Duties of the Master Servicer.

The Certificateholders, by their purchase and acceptance of the Certificates or Lower Tier REMIC I Uncertificated Regular Interests, appoint Wells Fargo Bank, N.A., as Master Servicer. For and on behalf of the Depositor, the Trustee and the Certificateholders, the Master Servicer shall master service the Mortgage Loans in accordance with the provisions of this Agreement and the provisions of each Servicing Agreement.

Section 9.02

Master Servicer Fidelity Bond and Master Servicer Errors and Omissions Insurance Policy.

(a)

The Master Servicer, at its expense, shall maintain in effect a Master Servicer Fidelity Bond and a Master Servicer Errors and Omissions Insurance Policy, affording coverage with respect to all directors, officers, employees and other Persons acting on such Master Servicer’s behalf, and covering errors and omissions in the performance of the Master Servicer’s obligations hereunder. The Master Servicer Errors and Omissions Insurance Policy and the Master Servicer Fidelity Bond shall be in such form and amount that would be consistent with coverage customarily maintained by master servicers of mortgage loans similar to the Mortgage Loans and the Master Servicer shall provide the Trustee upon request, with a copy of such policy and fidelity bond. The Master Servicer shall (i) require the Servicer to maintain an Errors and Omissions Insurance Policy and the Servicer Fidelity Bond in accordance with the provisions of the Servicing Agreement, (ii) cause the Servicer to provide to the Master Servicer certificates evidencing that such policy and bond is in effect and to furnish to the Master Servicer any notice of cancellation, non-renewal or modification of the policy or bond received by it, as and to the extent provided in the Servicing Agreement, and (iii) furnish copies of such policies and of the certificates and notices referred to in clause (ii) to the Trustee upon request.

(b)

The Master Servicer shall promptly report to the Trustee any material changes that may occur in the Master Servicer Fidelity Bond or the Master Servicer Errors and Omissions Insurance Policy and shall furnish to the Trustee, on request, certificates evidencing that such bond and insurance policy are in full force and effect. The Master Servicer shall promptly report to the Trustee all cases of embezzlement or fraud, if such events involve funds relating to the Mortgage Loans. The total losses, regardless of whether claims are filed with the applicable insurer or surety, shall be disclosed in such reports together with the amount of such losses covered by insurance. If a bond or insurance claim report is filed with any of such bonding companies or insurers, the Master Servicer shall promptly furnish a copy of such report to the Trustee. Any amounts relating to the Mortgage Loans collected by the Master Servicer under any such bond or policy shall be promptly deposited into the Certificate Account. Any amounts relating to the Mortgage Loans collected by the Servicer under any such bond or policy shall be remitted to the Master Servicer to the extent provided in the Servicing Agreement.

Section 9.03

Master Servicer’s Financial Statements and Related Information.

For each year this Agreement is in effect, the Master Servicer shall submit to the Trustee, each Rating Agency and the Depositor a copy of its annual unaudited financial statements on or prior to March 15 of each year, beginning March 15, 2007. Such financial statements shall include a balance sheet, income statement, statement of retained earnings, statement of additional paid-in capital, statement of changes in financial position and all related notes and schedules and shall be in comparative form, certified by a nationally recognized firm of Independent Accountants to the effect that such statements were examined and prepared in accordance with generally accepted accounting principles applied on a basis consistent with that of the preceding year.

Section 9.04

Power to Act; Procedures.

(a)

The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article X hereof, and the Servicer shall have full power and authority (to the extent provided in the 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 Servicing Agreement, as applicable; provided that the Master Servicer shall not take, or knowingly permit the 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 the 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 the Servicer, and the Servicer, to the extent such authority is delegated to such Servicer under the 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 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 the 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 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 the Servicer to service the Mortgage Loans, in each case in accordance with Accepted Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Master Servicer or the Servicer). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, then upon request of the Trustee the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 6.09 hereof. In 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 in its applicable, representative capacity, so long as the jurisdictional and procedural rules will allow for this insertion to occur, (ii) initiate any action, suit or proceeding not directly relating to the servicing of a Mortgage Loan (including but not limited to actions, suits or proceedings against Certificateholders, or against the Depositor or the Transferor for breaches of representations and warranties) solely under the Trustee’s name, (iii) engage counsel to represent the Trustee in any action, suit or proceeding not directly relating to the servicing of a Mortgage Loan (including but not limited to actions, suits or proceedings against Certificateholders, or against the Depositor or the Transferor for breaches of representations and warranties), or (iv) prepare, execute or deliver any government filings, forms, permits, registrations or other documents or take any action with the intent to cause, and that actually causes, 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 the Servicer to, in its discretion (i) waive any late payment charge (but not any Prepayment Premium, except as set forth below) 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 Servicing Agreement) to make Advances on the related Mortgage Loan in accordance with the provisions of Section 5.04 on the basis of the amortization schedule of such Mortgage Loan without modification thereof by reason of such extension. Notwithstanding anything to the contrary in this Agreement, the Master Servicer shall not make or knowingly permit any modification, waiver or amendment of any material term of any Mortgage Loan, unless: (1) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the Servicer, reasonably foreseeable, (2) in the case of a waiver of a Prepayment Premium, (a) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the Servicer, reasonably foreseeable and such waiver would maximize recovery of total proceeds taking into account the value of such Prepayment Premium and the related Mortgage Loan or (b) if the prepayment is not the result of a refinance by the Servicer or any of its affiliates and (i) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the Servicer, reasonably foreseeable and such waiver would maximize recovery of total proceeds taking into account the value of such Prepayment Premium and the related Mortgage Loan or (ii) the collection of the Prepayment Premium would be in violation of applicable law or (iii) the collection of such Prepayment Premium would be considered “predatory” pursuant to written guidance published or issued by any applicable federal, state or local regulatory authority acting in its official capacity and having jurisdiction over such matters and (3) the Master Servicer shall have provided or caused to be provided to the Trustee an Opinion of Counsel addressed to the Trustee (which opinion shall, if provided by the Master Servicer, be an expense reimbursed from the Certificate Account pursuant to Section 4.02(iv)) to the effect that such modification, waiver or amendment would not result in an Adverse REMIC Event; provided, in no event shall an Opinion of Counsel be required for the waiver of a Prepayment Premium under clause (2) above.

Section 9.05

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

(a)

Each Servicing Agreement requires the 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 the Servicer on behalf of the Master Servicer. Any fees and other amounts payable to the Servicer shall be deducted from amounts remitted to the Master Servicer by such Servicer (to the extent permitted by the Servicing Agreement) and shall not be an obligation of the Trust Fund, the Trustee or the Master Servicer.

(b)

The Master Servicer shall not be required to (i) take any action with respect to the servicing of any Mortgage Loan that the Servicer is not required to take under the Servicing Agreement and (ii) cause the Servicer to take any action or refrain from taking any action if the Servicing Agreement does not require such 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 such Servicer to take such action.

(c)

The Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of the Servicer under the Servicing Agreement, and shall, in the event that the 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 Agreement 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 Certificate Account.

(d)

The Master Servicer shall be entitled to conclusively rely on any certifications, reports or other information provided by the Servicer under the terms of the Servicing Agreement, in its preparation of any certifications, filings or reports, in accordance with the terms hereof or as may be required by applicable law or regulation.

Section 9.06

Collection of Taxes, Assessments and Similar Items.

(a)

To the extent provided in the Servicing Agreement, the Master Servicer shall cause the 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 the 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 Servicing Agreement. The 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 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 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 the 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 or the 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 the Servicer under the Servicing Agreement in accordance with the terms and conditions of the 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 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 the 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 of 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 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 the same obligations to make Advances as the Servicer under the Servicing Agreement and to reimburse the successor Servicer for unreimbursed Advances if required by the Servicing Agreement but 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 Servicing Agreement may be amended to provide that the successor Servicer shall have no obligation to make an Advance if it determines in its reasonable judgment that such Advance is non-recoverable and provides an Officer’s Certificate to such effect to the Master Servicer and the Trustee.

Section 9.08

Master Servicer Liable for Enforcement.

Notwithstanding any Servicing Agreement, the Master Servicer shall remain obligated and liable to the Trustee and the Certificateholders in accordance with the provisions of this Agreement, to the extent of its obligations hereunder, without diminution of such obligation or liability by virtue of such Servicing Agreements. The Master Servicer shall use commercially reasonable efforts to ensure that the Mortgage Loans are serviced in accordance with the provisions of this Agreement and shall use commercially reasonable efforts to enforce the provisions of each Servicing Agreement for the benefit of the Certificateholders. The Master Servicer shall be entitled to enter into any agreement with the 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 the Servicer in the performance by such Servicer of its obligations under the Servicing Agreement.

Section 9.09

No Contractual Relationship Between The 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 the Servicer in its capacity as such and not as an originator shall be deemed to be between such Servicer, the Seller and the Master Servicer, and the Trustee and the Depositor shall not be deemed parties thereto and shall have no obligations, duties or liabilities with respect to such Servicer except as set forth in Section 9.10 hereof, but shall have rights thereunder as third party beneficiaries. It is furthermore understood and agreed by the parties hereto that the obligations of the Servicer are set forth in their entirety in such Servicer’s Servicing Agreement and the 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), the Trustee shall, pursuant to Section 6.14 or Section 9.28, as applicable, thereupon assume all of the rights and obligations of such Master Servicer hereunder and under each Servicing Agreement entered into with respect to the Mortgage Loans. The Trustee, its designee or any successor master servicer appointed by the Trustee shall be deemed to have assumed all of the Master Servicer’s interest herein and therein to the same extent as if such Servicing Agreement had been assigned to the assuming party, except that the Master Servicer shall not thereby be relieved of any liability or obligations of the Master Servicer under such Servicing Agreement accruing prior to its replacement as Master Servicer, and shall be liable to the Trustee, and hereby agrees to indemnify and hold harmless the Trustee from and against all costs, damages, expenses and liabilities (including reasonable attorneys’ fees) incurred by the Trustee as a result of such liability or obligations of the Master Servicer and in connection with the Trustee’s assumption (but not its performance, except to the extent that costs or liability of the Trustee are created or increased as a result of negligent or wrongful acts or omissions of the Master Servicer prior to its replacement as Master Servicer) of the Master Servicer’s obligations, duties or responsibilities thereunder.

(b)

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

Section 9.11

Due-on-Sale Clauses; Assumption Agreements.

To the extent provided in the Servicing Agreement, to the extent Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer shall cause the Servicer to enforce such clauses in accordance with the 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 Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the original Mortgagor may be released from liability in accordance with the 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 Servicer to, promptly notify the Trustee (or the 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 Certificate Account 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 Custodian, to deliver to the Servicer the related Mortgage File. Upon receipt of such certification and request, the Trustee or the Custodian (with the consent, and at the direction of the Trustee), shall promptly release the related Mortgage File to the 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 the Servicer, to the extent such authority is provided for under the 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 Certificate 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 Servicing Agreement, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by the Master Servicer, or by the Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Trustee or the Custodian, shall, upon request of the Master Servicer, or of the Servicer, and delivery to the Trustee or the Custodian, of a request for release of documents and a 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 Servicer). Such receipt shall obligate the Master Servicer or Servicer to return the Mortgage File to the Trustee or the 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 receipt shall be released by the Trustee or the Custodian, as applicable, to the Master Servicer (or the 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 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 Servicing Agreement to be delivered to the Trustee or the Custodian. Any funds received by the Master Servicer or by the Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer or the 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 Certificate Account the Master Servicing Fee and other amounts provided in this Agreement and to the right of the Servicer to retain its Servicing Fee and other amounts as provided in the Servicing Agreement. The Master Servicer shall, and shall (to the extent provided in the Servicing Agreement) cause the Servicer to, provide access to information and documentation regarding the Mortgage Loans to the Trustee, 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. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

(b)

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

(c)

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

(d)

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

The Master Servicer agrees, to the extent provided in each Servicing Agreement, to cause the Servicer to present, on behalf of the Trustee and the Certificateholders, claims to the insurer under any Primary Mortgage Insurance Policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Primary Mortgage Insurance Policies respecting defaulted Mortgage Loans.

In the event that title to a Mortgaged Property is acquired in foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale shall be taken (pursuant to a limited power of attorney to be provided by the Trustee to the Master Servicer or the Servicer) in the name of the Trustee or a nominee thereof, on behalf of the Certificateholders, or in the event the Trustee or a nominee thereof is not authorized or permitted to hold title to real property in the state where the REO Property is located, or would be adversely affected under the “doing business” or tax laws of such state by so holding title, the deed or certificate of sale shall be taken in the name of such Person or Persons as shall be consistent with an Opinion of Counsel obtained by the Master Servicer or the Servicer from an attorney duly licensed to practice law in the state where the REO Property is located. Any Person or Persons holding such title other than the Trustee shall acknowledge in writing that such title is being held as nominee for the benefit of the Trustee. The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. The Master Servicer shall use its reasonable best efforts to sell, or cause the Servicer, to the extent provided in the Servicing Agreement any REO Property as expeditiously as possible and in accordance with the provisions of this Agreement and the Servicing Agreement, as applicable, but in all events within the time period, and subject to the conditions set forth in Article X hereof. Pursuant to its efforts to sell such REO Property, the Master Servicer shall protect and conserve, or cause the Servicer to protect and conserve, such REO Property in the manner and to such extent required by the Servicing Agreement, subject to Article X hereof.

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

(d)

The Liquidation Proceeds from the final disposition of the REO Property, net of any payment to the Master Servicer and the Servicer as provided above, shall be deposited in the Certificate Account on or prior to the Determination Date in the month following receipt thereof.

On or before March 1^st of each year, the Depositor shall distribute the information in Exhibit V to the Master Servicer.

The Master Servicer shall have no liability for any loss, expense, damage or claim arising out of or with respect to any failure to properly prepare and/or timely deliver all such information where such failure results from the Master Servicer’s inability or failure to obtain or receive, on a timely basis, any information from the Servicer needed to prepare or deliver such information, which failure does not result from the Master Servicer’s own negligence, bad faith or willful misconduct.

Section 9.24

(iii)

Promptly after receipt of each report on assessment of compliance, the Securities Administrator shall confirm that the assessments, taken as a whole, address all Servicing Criteria and taken individually address the Relevant Servicing Criteria (and disclose the inapplicability of the Servicing Criteria not determined to be Relevant Criteria) for each party as set forth on Exhibit S and on any similar exhibit set forth in each Servicing Agreement in respect of the Servicer, and the Custodial Agreement in respect of the Custodian, and shall notify the Depositor of any exceptions.

By March 15 of each year, commencing in March 2007, the Master Servicer, the Paying Agent and the Securities Administrator, each at its own expense, shall cause, and each such party shall cause any Servicing Function Participant engaged by it to cause, each at its own expense, a registered public accounting firm (which may also render other services to the Master Servicer, the Paying Agent and the Securities Administrator, as the case may be) that is a member of the American Institute of Certified Public Accountants to furnish a report to the Sponsor, the Depositor, the Master Servicer and the Securities Administrator, to the effect that (A) it has obtained a representation regarding certain matters from the management of such party, which includes an assertion that such party has complied with the Relevant Servicing Criteria, and (B) on the basis of an examination conducted by such firm in accordance with standards for attestation engagements issued or adopted by the PCAOB, it is expressing an opinion as to whether such party’s compliance with the Relevant Servicing Criteria was fairly stated in all material respects, or it cannot express an overall opinion regarding such party’s assessment of compliance with the Relevant Servicing Criteria. In the event that an overall opinion cannot be expressed, such registered public accounting firm shall state in such report why it was unable to express such an opinion. Such report must be available for general use and not contain restricted use language.

Promptly after receipt of such report from the Master Servicer, the Paying Agent, the Securities Administrator or any Servicing Function Participant engaged by such parties, the Securities Administrator shall confirm that each assessment submitted pursuant subsection (a) of this Section 9.25 is coupled with an attestation meeting the requirements of this Section and notify the Depositor of any exceptions.

(c)

The Paying Agent’s obligation to provide assessments of compliance and attestations under this Section 9.25 shall terminate upon the filing of a Form 15 suspension notice on behalf of the Trust Fund.

Except as otherwise provided in Sections 9.27 and 9.29 hereof, the Master Servicer shall not resign from the obligations and duties hereby imposed on it unless it determines that the Master Servicer’s duties hereunder are no longer permissible under applicable law or are in material conflict by reason of applicable law with any other activities carried on by it and cannot be cured. Any such determination permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel that shall be Independent to such effect delivered to the Trustee.

Section 9.30

Limitation on Liability of the Master Servicer and Others.

(a)

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

(b)

No provision of this Agreement shall be construed to relieve the Master Servicer from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that the duties and obligations of the Master Servicer shall be determined solely by the express provisions of this Agreement, the Master Servicer shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement; no implied covenants or obligations shall be read into this Agreement against the Master Servicer and, in absence of bad faith on the part of the Master Servicer, the Master Servicer may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Master Servicer and conforming to the requirements of this Agreement.

(c)

None of the Master Servicer, the Seller or the Depositor or any of the directors, officers, employees or agents of any of them shall be under any liability to the Trustee or the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Master Servicer, the Seller or the Depositor or any such person against any liability that would otherwise be imposed by reason of willful misfeasance, bad faith or negligence in its performance of its duties or by reason of reckless disregard for its obligations and duties under this Agreement. The Master Servicer and any director, officer, employee or agent of any of them shall be entitled to indemnification by the Trust Fund and will be held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Agreement or the Certificates other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of its duties hereunder or by reason of reckless disregard of his or its obligations and duties hereunder.

The Master Servicer, the Seller and the Depositor shall be under no obligation to appear in, prosecute or defend any legal action that is not incidental to its duties to master service the Mortgage Loans in accordance with this Agreement and that in its opinion may involve it in any expenses or liability; provided, however, that the Master Servicer may in its sole discretion undertake any such action that it may deem necessary or desirable in respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund and the Master Servicer shall be entitled to be reimbursed therefor out of the Certificate Account as provided by Section 4.02.

The Master Servicer shall not be liable for any acts or omissions of the Servicer.

Section 9.31

The regular interests and residual interest in each REMIC shall be as designated in the Preliminary Statement. For purposes of such designations, the interest rate of any regular interest that is computed by taking into account the weighted average of the Net Mortgage Rates of the Mortgage Loans shall be reduced by the amount of any expense paid by the Trust to the extent that (i) such expense was not taken into account in computing the Net Mortgage Rate of any Mortgage Loan, (ii) such expense does not constitute an “unanticipated expense” of a REMIC within the meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii) and (iii) the amount of such expense was not taken into account in computing the interest rate of a more junior Class of regular interests.

(b)

The Closing Date is hereby designated as the “Startup Day” of each REMIC within the meaning of section 860G(a)(9) of the Code. The latest possible maturity date for purposes of Treasury Regulation 1.860G-1(a)(4) will be the Latest Possible Maturity Date.

(c)

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 Certificate 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 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 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 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 or the Master Servicer has advised it in writing that an Adverse REMIC Event could occur.

(g)

Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on the related REMIC by federal or state governmental authorities. To the extent that such taxes are not paid by a Residual Certificateholder, the Securities Administrator 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 Certificate 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.

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 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 solely 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 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); provided, however, that this sentence shall not apply in connection with any failure by the Securities Administrator to comply with the provisions of Subsections 6.01(l) hereof and Subsections 9.25(a) or (b) hereof. 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.

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 Servicing Agreement, knowingly permit the 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 Servicer to advise, the Trustee in writing to the effect that, under the REMIC Provisions, such action would not result in an Adverse REMIC Event.

(b)

The Master Servicer shall cause the 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 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 Master Servicer shall, or shall cause the 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 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 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 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 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.

Dear Sirs:

In connection with our proposed purchase of $______________ principal amount of TBW Mortgage-Backed Trust Mortgage Pass-Through Certificates, Series 2006-3, [Class B1] [Class B2] Certificates (the “Privately Offered Certificates”) of the Structured Asset Securities Corporation (the “Depositor”), we confirm that:

(1)

We understand that the Privately Offered Certificates have not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), and may not be sold except as permitted in the following sentence. 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 Securities Administrator under the Trust Agreement dated as of June 1, 2006 by and among the Depositor, U.S. Bank National Association, as Trustee (the “Trustee”) and Wells Fargo Bank, N.A., as Master Servicer and Securities Administrator, a signed letter in the form of this letter; and we further agree, in the capacities stated above, to provide to any person purchasing any of the Privately Offered Certificates from us a notice advising such purchaser that resales of the Privately Offered Certificates are restricted as stated herein.

(2)

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

(3)

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

(4)

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

(5)

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

(6)

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

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

You and the Depositor are entitled to rely upon this letter and are irrevocably authorized to produce this letter or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.
