Each Certificate, other than the Class R Certificate represents ownership of a regular interest in the Upper Tier REMIC for purposes of the REMIC Provisions. In addition, each of the Class A Certificates, represents the right to receive payments with respect to Available Funds Cap Shortfalls pursuant to Sections 5.06 and 5.07 hereof. The Class R Certificate represents ownership of the sole class of residual interest in each of REMIC 1, REMIC 2 and the Upper Tier REMIC for purposes of the REMIC Provisions.

The Upper Tier REMIC shall hold as its assets the several classes of uncertificated Lower Tier Regular Interests in REMIC 2, and each such Lower Tier Regular Interest is hereby designated as a regular interest in REMIC 2 for purposes of the REMIC Provisions. REMIC 2 shall hold as its assets the several classes of uncertificated Lower Tier Regular Interests in REMIC 1, and each such Lower Tier Regular Interest is hereby designated as a regular interest in REMIC 1. REMIC 1 shall hold as its assets the property of the Trust other than the Lower Tier Regular Interests in REMIC 1, REMIC 2 and the Excluded Assets.

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.

In instances where a Title Insurance Policy is required to be delivered to the Trustee, or to the Custodian on behalf of the Trustee, under clause (c)(viii) above and is not so delivered, the Seller will provide a copy of such Title Insurance Policy to the Trustee, or to the Custodian on behalf of the Trustee, as promptly as practicable after the execution and delivery hereof, but in any case within 180 days of the Closing Date.

(f)

For Mortgage Loans (if any) that have been prepaid in full after the Cut-off Date and prior to the Closing Date (or, in the case of Subsequent Mortgage Loans, after the applicable Subsequent Cut-off Date and prior to the applicable Transfer Date), the Seller, 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 Collection 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 applicable Servicer in trust for the benefit of the Trustee and the Certificateholders.

(g)

With respect to each Mortgage Loan as to which a Lost Note Affidavit has been delivered in lieu of an original Mortgage Note, the Seller indemnifies the Trustee and the Trust and holds them harmless against any losses resulting from an inability to enforce the Mortgagor's obligations under such Mortgage Loan or to foreclose on the related Mortgaged Property, or any reduction in Liquidation Proceeds on foreclosure, or any other loss, in each case resulting from lack of possession of the original Mortgage Note.

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 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 Trustee and the Depositor on the Closing Date a Receipt of Notes in the form annexed hereto as Exhibit B-1.

(b)

Within 90 days after the Closing Date (or, in the case of Subsequent Mortgage Loans, within 45 days after the applicable Transfer Date), the Custodian will, on behalf of the Trustee and for the benefit of Holders of the Certificates, review each Mortgage File to ascertain that all required documents set forth in Section 2.01 have been received and appear on their face to contain the requisite signatures by or on behalf of the respective parties thereto, and shall deliver to the Trustee and the Depositor an Interim Certification in the form annexed hereto as Exhibit B-2. 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)

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

(d)

If in the course of the review described in paragraphs (b) and (c) above, the Trustee or the Custodian (or WFB, as Servicer) discovers any document or documents constituting a part of a Mortgage File that is missing, does not appear regular on its face (i.e., is mutilated, damaged, defaced, torn or otherwise physically altered) or appears to be unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule (each, a “Material Defect”), the Trustee, or the Custodian on behalf of the Trustee, shall promptly identify the Mortgage Loan to which such Material Defect relates in the Interim Certification or the Final Certification, as applicable, delivered to the Depositor and the Trustee. Within 90 days of its receipt of such notice, 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 Depositor does not so cure such Material Defect, it shall, if a loss has been incurred with respect to such Mortgage Loan that would, if such Mortgage Loan were not purchased from the Trust Fund, constitute a Realized Loss, and such loss is attributable to the failure of the 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 Seller 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 90 days after the Closing Date (or, in the case of Subsequent Mortgage Loans, within 45 days after the applicable Transfer 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.

(e)

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

(f)

Each of the parties hereto acknowledges that the Trustee or the Custodian shall perform the applicable review of the Mortgage Loans and deliver the respective certifications thereof as provided in this Section 2.02.

Section 2.03. Representations and Warranties of the Depositor.

(a)

The Depositor hereby represents and warrants to the Trust, for the benefit of Certificateholders, and to the Master Servicer and the Securities Administrator, as of the Closing Date and the applicable Transfer Date (except in the case of clause (vi) and a Transfer Date, only relating to the applicable Subsequent Mortgage Loans), 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 Trust, 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 Trust 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)

Except as set forth in Section 2.03(a)(vi), the Depositor shall have no obligation or liability with respect to any breach of any representation or warranty with respect to the Mortgage Loans under any circumstances.

(c)

It is understood and agreed that the representations and warranties of the Depositor set forth in Sections 2.03(a)(i) through (vi) shall survive the execution and delivery of this Agreement. The Depositor shall indemnify the Trust, the Master Servicer, the Securities Administrator and the Trustee and hold each of the Trust, the Master Servicer, the Securities Administrator and the Trustee harmless against any loss, damages, penalties, fines, forfeitures, legal fees and related costs, judgments, and other costs and expenses resulting from any claim, demand, defense or assertion based on or grounded upon, or resulting from, a breach of the Depositor’s representations and warranties contained in Sections 2.03(a)(i) through (vi) hereof. It is understood and agreed that the enforcement of the obligation of the Depositor set forth in this Section to indemnify the Trust, the Master Servicer, the Securities Administrator and the Trustee as provided in this Section constitutes the sole remedy of the Master Servicer, the Securities Administrator and the Trustee respecting a breach by the Depositor of the representations and warranties in Sections 2.03(a)(i) through (vi) hereof.

Any cause of action against the Depositor relating to or arising out of the breach of the representations and warranties made in Sections 2.03(a)(i) through (vi) hereof shall accrue upon discovery of such breach by the Depositor, the Securities Administrator or the Master Servicer or receipt of actual knowledge by a Responsible Officer of the Trustee or notice thereof by any one of such parties to the other parties.

Section 2.04. Discovery of Breach.

It is understood and agreed that the representations and warranties (i) set forth in Section 2.03 and (ii) of the Seller set forth in the Mortgage Loan Purchase Agreement and assigned to the Trust or the Trustee on behalf of the Trust by the Depositor hereunder shall each survive delivery of the Mortgage Files and the Assignment of Mortgage of each Mortgage Loan to the Trustee on behalf of the Trust and shall continue throughout the term of this Agreement. Upon discovery by any of the Depositor, the Master Servicer or the Securities Administrator of, or the receipt of actual knowledge by a Responsible Officer of 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 Trust or the Trustee on behalf of the Trust by the Depositor or the Seller and assigned to the Trust or the Trustee on behalf of the Trust, the Depositor 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 Trust 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.

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 or by the Seller pursuant to the Mortgage Loan Purchase 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 Collection Account. The Trustee, upon receipt of certification from the Master Servicer that the full amount of the Purchase Price for a Deleted Mortgage Loan has been deposited to the Collection Account, or upon receipt of the Mortgage File for a Qualifying Substitute Mortgage Loan substituted for a Deleted Mortgage Loan (and any applicable Substitution Amount), shall release or cause to be released and reassigned to the Depositor or the Seller, 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, 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, the Trustee, the Depositor, the Securities Administrator 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, the Trustee, the Securities Administrator, the Depositor and any Certificateholder may sustain in connection with any actions of the Seller relating to a repurchase of a Mortgage Loan other than in compliance with the terms of this Section 2.05 and the Mortgage Loan Purchase Agreement, to the extent that any such action causes (i) any federal or state tax to be imposed on the Trust Fund, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(2) of the Code or (ii) any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding.

(b)

With respect to each Qualifying Substitute Mortgage Loan to be delivered to the Trustee (or the Custodian, on its behalf) pursuant to the terms of this Article II in exchange for a Deleted Mortgage Loan: (i) the Depositor or the Seller must deliver to the Trustee (or the Custodian, on its behalf) the Mortgage File for the Qualifying Substitute Mortgage Loan containing the documents set forth in Section 2.01(b) along with a written certification certifying as to the delivery of such Mortgage File and containing the granting language set forth in Section 2.01(a); and (ii) the Depositor and the Seller will each 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 applicable Servicer, at the expense of the Seller, 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 such Servicer if required pursuant to Section 2.01(c)(i) 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 Trust to be clearly identified as the owner of each such Mortgage Loan on the records of MERS if required pursuant to Section 2.01(c)(ii).

(c)

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

Section 2.06. Securitization Act; Grant Clause.

(a)

For purposes of complying with the requirements of the Asset-Backed Securities Facilitation Act of the State of Delaware, 6 Del. C. § 2701A, et seq. (the “Securitization Act”), each of the Seller, the Depositor and the Trustee hereby agree that:

(i)

any property, assets or rights purported to be transferred, in whole or in part, by the Depositor pursuant to this Agreement shall be deemed to no longer be the property, assets or rights of the Depositor;

(ii)

none of the Depositor, its creditors or, in any insolvency proceeding with respect to the Depositor or the Depositor’s property, a bankruptcy trustee, receiver, debtor, debtor in possession or similar person, to the extent the issue is governed by Delaware law, shall have any rights, legal or equitable, whatsoever to reacquire (except pursuant to a provision of this Agreement), reclaim, recover, repudiate, disaffirm, redeem or recharacterize as property of the Depositor any property, assets or rights purported to be transferred, in whole or in part, by the Depositor pursuant to this Agreement;

(iii)

in the event of a bankruptcy, receivership or other insolvency proceeding with respect to the Depositor or the Depositor's property, to the extent the issue is governed by Delaware law, such property, assets and rights shall not be deemed to be part of the Depositor's property, assets, rights or estate; and

(iv)

the transaction contemplated by this Agreement shall constitute a “securitization transaction” as such term is used in the Securitization Act.

(b)

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: (i) the rights and obligations of the parties shall be established pursuant to the terms of this Agreement; (ii) the Depositor hereby grants to the Trustee on behalf of the Trust and for the benefit of the Holders of the Certificates a first priority security interest to secure repayment of an obligation in an amount equal to the aggregate Class Principal Amount of the Certificates in all of the Depositor’s right, title and interest in, to and under, whether now owned or hereafter acquired, the Trust Fund and the Final Maturity Reserve Account and all proceeds of any and all property constituting the Trust Fund and the Final Maturity Reserve Account to secure payment of the Certificates; and (iii) this Agreement shall constitute a security agreement under applicable law. If such conveyance is deemed to be in respect of a loan and the Trust created by this Agreement terminates prior to the satisfaction of the claims of any Person holding any Certificate, the security interest created hereby shall continue in full force and effect and the Trustee shall be deemed to be the collateral agent for the benefit of such Person, and all proceeds shall be distributed as herein provided.

(c)

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

Section 2.07. Amendments to Master Servicing Guide and Correspondent Sellers Guide.

The Seller and the Master Servicer hereby agree not to amend the Master Servicing Guide or the Correspondent Sellers Guide with respect to the Mortgage Loans which amendment would (i) change the Remittance Date or date for remittance of any servicer reports or monthly remittance advices, (ii) change the manner in which any Servicer makes Advances, Servicing Advances or amounts to compensate for Prepayment Interest Shortfalls or (iii) otherwise have a material adverse effect on Certificateholders unless the same consents as required by Section 11.03 hereof are procured.

Section 2.08

Representations and Warranties of the Seller.

The Seller hereby represents and warrants to the Trust and the Trustee on behalf of the Certificateholders that, as of the Closing Date and the applicable Transfer Date (except in the case of clauses (vi), (vii) and (x) and a Transfer Date, only relating to the applicable Subsequent Mortgage Loans), or as of such date specifically provided herein:

(iii)

the execution and delivery of this Agreement by the Seller and the performance of and compliance with the terms of this Agreement will not violate the Seller’s articles of incorporation or by-laws or constitute a default under or result in a material breach or acceleration of, any material contract, agreement or other instrument to which the Seller is a party or which may be applicable to the Seller or its assets;

(iv)

the Seller is not in violation of, and the execution and delivery of this Agreement by the Seller and its performance and compliance with the terms of this Agreement will not constitute a violation with respect to, any order or decree of any court or any order or regulation of any federal, state, municipal or governmental agency having jurisdiction over the Seller or its assets, which violation might have consequences that would materially and adversely affect the condition (financial or otherwise) or the operation of the Seller or its assets or might have consequences that would materially and adversely affect the performance of its obligations and duties hereunder;

(v)

the Seller does not believe, nor does it have any reason or cause to believe, that it cannot perform each and every covenant contained in this Agreement;

(vi)

the Seller has good, marketable and indefeasible title to the Mortgage Loans, free and clear of any and all liens, pledges, charges or security interests of any nature encumbering the Mortgage Loans and upon the payment of the purchase price under the Mortgage Loan Purchase Agreement by the Depositor, the Depositor will have good and marketable title to the Mortgage Notes and Mortgage Loans, free and clear of all liens or encumbrances;

(vii)

the Mortgage Loans are not being transferred by the Seller with any intent to hinder, delay or defraud any creditors of the Seller;

(viii)

there are no actions or proceedings against, or investigations known to it of, the Seller before any court, administrative or other tribunal (A) that might prohibit its entering into this Agreement, (B) seeking to prevent the sale of the Mortgage Loans or the consummation of the transactions contemplated by this Agreement or (C) that might prohibit or materially and adversely affect the performance by the Seller of its obligations under, or validity or enforceability of, this Agreement;

(ix)

no consent, approval, authorization or order of any court or governmental agency or body is required for the execution, delivery and performance by the Seller of, or compliance by the Seller with, this Agreement or the consummation of the transactions contemplated by this Agreement, except for such consents, approvals, authorizations or orders, if any, that have been obtained; and

(x)

the consummation of the transactions contemplated by this Agreement are in the ordinary course of business of the Seller, and the transfer, assignment and conveyance of the Mortgage Notes and the Mortgages by the Seller pursuant to the Mortgage Loan Purchase Agreement are not subject to the bulk transfer or any similar statutory provisions.

Section 2.09

Covenants of the Seller.

The Seller hereby covenants that, except for the transfer hereunder, the Seller will not sell, pledge, assign or transfer to any other Person, or grant, create, incur, assume or suffer to exist any lien on any Mortgage Loan, or any interest therein; the Seller will notify the Trustee, as assignee of the Depositor, and the Master Servicer of the existence of any lien on any Mortgage Loan immediately upon discovery thereof, and the Seller will defend the right, title and interest of the Trust, as assignee of the Depositor, in, to and under the Mortgage Loans, against all claims of third parties claiming through or under the Seller; provided, however, that nothing in this Section 2.09 shall prevent or be deemed to prohibit the Seller from suffering to exist upon any of the Mortgage Loans any liens for municipal or other local taxes and other governmental charges if such taxes or governmental charges shall not at the time be due and payable or if the Seller shall currently be contesting the validity thereof in good faith by appropriate proceedings and shall have set aside on its books adequate reserves with respect thereto.

ARTICLE III

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 shall be issued in the minimum denominations in Certificate Principal Amount or Percentage Interest specified in the Preliminary Statement hereto and in integral multiples of $1 or 5% (in the case of Certificates issued in Percentage Interests) in excess thereof. Each Class of Non-Book Entry Certificates other than the Residual Certificate shall be issued in definitive, fully registered form in the minimum denominations in Certificate Principal Amount specified in the Preliminary Statement hereto and in integral multiples of $1 in excess thereof. The Residual Certificate and the Class I Certificate shall each be issued as a single Certificate and maintained in definitive, fully registered form in a minimum denomination equal to 100% of the Percentage Interest of such Class. The Certificates may be issued in the form of typewritten certificates. One Certificate of each Class of Certificates other than any Class of Residual Certificates or Class I Certificates may be issued in any denomination in excess of the minimum denomination.

(b)

The Certificates shall be executed by manual or facsimile signature by an authorized officer of the Securities Administrator on behalf of the Trust. Each Certificate shall, on original issue, be authenticated by the Securities Administrator upon the written order of the Depositor upon receipt by the Trustee of the Mortgage Files described in Section 2.01. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided for herein, executed by an authorized officer of the 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 Class B4, Class B5 or Class B6 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 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.

The Class B4, Class B5 or Class B6 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.

(d)

The Class B4, Class B5, or Class B6 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 shall maintain books for the registration and for the transfer of Certificates (the “Certificate Register”). The Trustee may appoint a bank or trust company to act as successor Certificate Registrar. A registration book shall be maintained for the Certificates collectively. The Certificate Registrar may resign or be discharged or removed and a new successor may be appointed in accordance with the procedures and requirements set forth in Sections 6.06 and 6.07 hereof with respect to the resignation, discharge or removal of the 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.

Section 3.03. Transfer and Exchange of Certificates.

(a)

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

(b)

A Certificate may be exchanged by the Holder thereof for any number of new Certificates of the same Class, in authorized denominations, representing in the aggregate the same Certificate Principal Amount as the Certificate surrendered, upon surrender of the Certificate to be exchanged at the office of the Certificate Registrar duly endorsed or accompanied by a written instrument of transfer duly executed by such Holder or his duly authorized attorney in such form as is satisfactory to the Certificate Registrar. Certificates delivered upon any such exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Certificates surrendered. No service charge shall be made to a Certificateholder for any exchange of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates. Whenever any Certificates are so surrendered for exchange, the 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 (A) if the offer or sale was made to it prior to the expiration of the 40-day distribution compliance period within the meaning of Regulation S, is not a U.S. person within the meaning of Regulation S and (B) was, at the time the offer was made to it and the buy order was originated, outside the United States and (ii) such Person understands that such Certificates have not been registered under the Securities Act of 1933, as amended (the “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, (B) in an offshore transaction (as defined in Regulation S) in compliance with the provisions of Regulation S, or (C) to a person which the seller reasonably believes is an “accredited investor” under Rule 501(a)(1), (2), (3) or (7) under the Act, which accredited investor is purchasing such Certificate in the form of a Definitive Certificate, 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, the Seller or the Placement Agent, an affiliate (as defined in Rule 405 under the Securities Act) of the Depositor, the Seller or the Placement Agent or (y) being made to a QIB 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 by a transferor who furnishes to the Securities Administrator a letter of the transferee substantially in the form of Exhibit G hereto.

(d)

No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate shall be made to any Person unless the Securities Administrator has received (A) an affidavit substantially in the form of Exhibit H (or Exhibit D-1 in the case of the Class R Certificate) hereto from such transferee or (B) an Opinion of Counsel satisfactory to the Securities Administrator (on which the Securities Administrator, the Master Servicer, the Trustee, any Servicer and the Depositor may explicitly rely) to the effect that the purchase and holding of such a Certificate will not constitute or result in any non-exempt prohibited transactions under Title I of ERISA or Section 4975 of the Code and will not subject the Securities Administrator, the Depositor, the Master Servicer, any Servicer or the Trustee to any obligation in addition to those undertaken in the Agreement. 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 or any of the above parties. 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.

No transfer of an ERISA-Restricted Final Maturity Reserve Certificate in the form of a Definitive Certificate shall be made to any Person unless the Securities Administrator has received (A) a representation substantially in the form of Exhibit F or Exhibit G hereto from such transferee, or (B) the acquisition and holding of such Certificate are eligible for exemptive relief available under Prohibited Transaction Class Exemptions (“PTCE”) 84-14, 90-1, 91-38, 95-60 or 96-23 or some other applicable exemption. Each transferee of an ERISA-Restricted Final Maturity Reserve Certificate that is a Book Entry Certificate shall be deemed to have made the representations set forth above. The preparation and delivery of the certificates referred to above shall not be an expense of the Trust or any of the above parties. The Securities Administrator shall have no obligation to monitor transfers of Book-Entry Certificates that are ERISA-Restricted Final Maturity Reserve Certificate 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 or ERISA-Restricted Final Maturity Reserve 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 or ERISA-Restricted Final Maturity Reserve Certificate that was in fact an employee benefit plan subject to Section 406 of ERISA or a plan subject to Section 4975 of the Code or a Person acting on behalf of any such plan at the time it became a Holder or, at such subsequent time as it became such a plan or Person acting on behalf of such a plan, all payments made on such ERISA-Restricted Certificate or ERISA-Restricted Final Maturity Reserve 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 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 Form W-8ECI or successor form at the time and in the manner required by the Code (any such person who is not covered by clause (A) or (B) above is referred to herein as a “Non-permitted Foreign Holder”).

Prior to and as a condition of the registration of any transfer, sale or other disposition of a Residual Certificate, the proposed transferee shall deliver to the 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 and the Securities Administrator satisfactory in form and substance to the Depositor, that such proposed transferee or, if the proposed transferee is an agent or nominee, the proposed beneficial owner, is not a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder. Notwithstanding the registration in the Certificate Register of any transfer, sale, or other disposition of a Residual Certificate to a Disqualified Organization, an agent or nominee thereof, or Non-permitted Foreign Holder, such registration shall be deemed to be of no legal force or effect whatsoever and such Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder shall not be deemed to be a Certificateholder for any purpose hereunder, including, but not limited to, the receipt of distributions on such Residual Certificate. The 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 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, agent or nominee thereof, or Non-permitted Foreign Holder. The Securities Administrator shall be entitled to recover from any Holder of a Residual Certificate that was a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder at the time it became a Holder or any subsequent time it became a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder, all payments made on such Residual Certificate at and after either such times (and all costs and expenses, including but not limited to attorneys’ fees, incurred in connection therewith). Any payment (not including any such costs and expenses) so recovered by the 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 of a Residual Certificate, by such Holder’s acceptance thereof, shall be deemed for all purposes to have consented to the provisions of this section.

(h)

Notwithstanding any provision to the contrary herein, so long as a Global Security representing any of the Class B4, Class B5 or Class B6 Certificates remains outstanding and is held by or on behalf of DTC, transfers of interests in a Global Security representing any such Certificates, in whole or in part, shall only be made in accordance with Section 3.01, Section 3.03 and Section 3.09.

(i)

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

(ii)

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 cause to be credited a beneficial interest in a Regulation S Global Security in an amount equal to the beneficial interest in such Restricted Global Security to be exchanged but not less than the minimum denomination applicable to such holder’s Certificates held through a Regulation S Global Security, (II) a written order given in accordance with DTC’s procedures containing information regarding the participant account of DTC and, in the case of a transfer pursuant to and in accordance with Regulation S, the Euroclear or Clearstream account to be credited with such increase and (III) a certificate in the form of Exhibit N-1 hereto given by the holder of such beneficial interest stating that the exchange or transfer of such interest has been made in compliance with the transfer restrictions applicable to the Regulation S Global Securities, including that the holder is not a U.S. person, and pursuant to and in accordance with Regulation S, the 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.

(iii)

Regulation S Global Security to Restricted Global Security. If a holder of a beneficial interest in a Regulation S Global Security deposited with or on behalf of DTC wishes at any time to transfer its interest in such Regulation S Global Security to a Person who wishes to take delivery thereof in the form of an interest in a Restricted Global Security, such holder may, subject to the rules and procedures DTC, exchange or cause the exchange of such interest for an equivalent beneficial interest in a Restricted Global Security. Upon receipt by the 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 N-2 hereto given by the holder of such beneficial interest and stating, among other things, that the Person transferring such interest in such Regulation S Global Security reasonably believes that the Person acquiring such interest in a Restricted Global Security is a QIB, is obtaining such beneficial interest in a transaction meeting the requirements of Rule 144A and in accordance with any applicable securities laws of any State of the United States or any other jurisdiction, then the 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.

(iv)

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.

(v)

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

Section 3.04. Cancellation of Certificates.

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

Section 3.05. Replacement of Certificates.

If (i) any Certificate is mutilated and is surrendered to the Securities Administrator or any Authenticating Agent or (ii) the Securities Administrator or any Authenticating Agent receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and there is delivered to the Securities Administrator or the Authenticating Agent such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Depositor and any Authenticating Agent that such destroyed, lost or stolen Certificate has been acquired by a bona fide purchaser, the Securities Administrator shall execute and the Securities Administrator or any Authenticating Agent shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and Certificate Principal Amount. Upon the issuance of any new Certificate under this Section 3.05, the 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 none of 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.

Section 3.07. Temporary Certificates.

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

(b)

If temporary Certificates are issued, the Depositor will cause definitive Certificates to be prepared without unreasonable delay. After the preparation of definitive Certificates, the temporary Certificates shall be exchangeable for definitive Certificates upon surrender of the temporary Certificates at the office or agency of the 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.

The Trustee may appoint a successor Paying Agent (which may be the Trustee) for the purpose of making distributions to Certificateholders hereunder. The Trustee shall cause such Paying Agent (if other than the Trustee or the Securities Administrator) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee that such Paying Agent will hold all sums held by it for the payment to Certificateholders in an Eligible Account in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to the Certificateholders. All funds remitted by the 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.

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

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

(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 Securities Administrator or the Depositor is unable to locate a qualified successor, (ii) the Depositor, at its option, advises the Securities Administrator in writing that it elects to terminate the book-entry system through the Clearing Agency or (iii) 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 transferor 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.

All such investments must mature no later than the next Distribution Date, and shall not be sold or disposed of prior to their maturity. All such Eligible Investments will be made in the name of the Trustee (in its capacity as such) or its nominee. All investment earnings, income, or gain on amounts on deposit in the Certificate Account from time to time shall be for the account of ▇▇▇▇▇▇▇▇▇ (in its capacity as a Servicer).

(b)

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

All of the Securities Administrator’s calculations of payments shall be based solely on information provided to the Securities Administrator by the Master Servicer.

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

(d) On each Distribution Date, the Securities Administrator shall distribute to the Holder of the Class R Certificate any amounts remaining in REMIC 1 or REMIC 2 for such Distribution Date after application of all amounts described in paragraph (a) of this Section 5.02.

(i) to the Class A1, Class A2 and Class A4 Certificates, concurrently, in proportion to their respective Class Principal Amounts, after giving effect to principal distributions on such Distribution Date pursuant to Section 5.02(a)(iv) above, in reduction of their respective Class Principal Amounts, until the Class Principal Amount of each such Class has been reduced to zero;

(ii) to the Class B1, Class B2, Class B3, Class B4, Class B5 and Class B6 Certificates, in that order, after giving effect to principal distributions on such Distribution Date pursuant to Section 5.02(a)(v) above, in reduction of their respective Class Principal Amounts, until the Class Principal Amount of each such class has been reduced to zero;

Section 5.03. Allocation of Realized Losses.

(a)

On any Distribution Date, the principal portion of each Realized Loss in respect of a Mortgage Loan in each Mortgage Pool shall be allocated in the following order of priority:

first, to the Class B6 Certificates, until the Class Principal Amount thereof has been reduced to zero;

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

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

(b)

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

(c)

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.

(d)

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

Section 5.04. Advances by Master Servicer.

(a)

Advances shall be made in respect of each Deposit Date as provided herein. If, on any Determination Date, any Servicer determines that any Scheduled Payments due during the related Due Period (other than Balloon Payments) have not been received, such Servicer shall advance such amount to the extent provided in the applicable Servicing Agreement. If any Servicer fails to remit Advances required to be made under the applicable Servicing Agreement, the Master Servicer shall itself (in its capacity as successor Servicer) make, or shall cause the successor Servicer to make such advance on the Deposit Date immediately following such Determination Date. The Master Servicer shall: (i) remit Advances to the Securities Administrator from funds advanced by the applicable Servicer (or from its own funds to the extent it is successor Servicer) for deposit in the Certificate Account in immediately available funds in an amount equal to such Advance, (ii) cause to be made an appropriate entry in the records of the Collection Account that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 5.04, used by the Master Servicer to make such Advance, and remit such immediately available funds to the Securities Administrator for deposit in the Certificate Account or (iii) make Advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any funds being held in the Collection Account for future distribution to Certificateholders and so used shall be replaced by the Master Servicer from its own funds by remittance to the Securities Administrator for deposit in the Certificate Account on or before any future Deposit Date to the extent that funds in the Certificate Account on such Deposit Date shall be less than payments to Certificateholders required to be made on the related Distribution Date. The Master Servicer and each Servicer shall be entitled to be reimbursed from the Collection Account for all Advances made by it as provided in Section 4.02. Notwithstanding anything to the contrary herein, in the event the Master Servicer determines in its reasonable judgment that an Advance is non-recoverable, the Master Servicer shall be under no obligation to make such Advance.

(b)

In the event that the Master Servicer or Servicer fails for any reason to make an Advance required to be made pursuant to Section 5.04(a) on or before the Deposit Date, the Trustee, solely in its capacity as successor Master Servicer pursuant to Section 6.14, shall, on or before the related Distribution Date, deposit in the Certificate Account an amount equal to the excess of (a) Advances required to be made by the Master Servicer or any Servicer that would have been deposited in such Certificate Account over (b) the amount of any Advance made by the Master Servicer or such Servicer with respect to such Distribution Date; provided, however, that the Trustee shall be required to make such Advance only if it is not prohibited by law from doing so and it has determined that such Advance would be recoverable from amounts to be received with respect to such Mortgage Loan, including late payments, Liquidation Proceeds, Insurance Proceeds, or otherwise. The Trustee shall be entitled to be reimbursed from the Certificate Account for Advances made by it pursuant to this Section 5.04 as if it were the Master Servicer. The Securities Administrator shall not later than 5:00 P.M. (Chicago time) on the Deposit Date notify the Trustee in writing of the Master Servicer’s failure to make any Advance required to be made under this Agreement on the Deposit Date and the amount of such Advance. By no later than 10:00 A.M. (Chicago time) on the relevant Distribution Date, the Securities Administrator shall notify the Trustee of the continuance of such failure and the occurrence of an Event of Default under Section 6.14 or that the Master Servicer has made the Advance, as the case may be.

Section 5.05. Compensating Interest Payments.

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

Section 5.06. Available Funds Cap Reserve Fund.

(a) On the Closing Date, the Securities Administrator shall establish and maintain in its name, in trust for the benefit of the holders of the Class A1, Class A2, Class A3, Class A4 and Class A-X Certificates, an Available Funds Cap Reserve Fund, into which the Seller shall deposit $1,000. The Available Funds Cap Reserve Fund shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other moneys, including, without limitation, other moneys of the Securities Administrator held pursuant to this Agreement. The Available Funds Cap Reserve Fund shall not be an asset of any REMIC established hereby.

(b) On each Distribution Date, Accrued Certificate Interest that would otherwise be distributable with respect to the Class A-X Certificates shall instead be deposited in the Available Funds Cap Reserve Fund to the extent of the Required Reserve Fund Deposit.

(c) On any Distribution Date for which Available Funds Cap Shortfall Amounts exist with respect to the Class A1, Class A2, Class A3 or Class A4 Certificates after giving effect to payments made from funds on deposit in the Yield Maintenance Accounts, the Securities Administrator shall withdraw from the Available Funds Cap Reserve Fund, the amount on deposit therein required to be distributed on such Distribution Date pursuant to Section 5.02(f).

(d) Funds in the Available Funds Cap Reserve Fund shall be invested in Eligible Investments. Any earnings on amounts in the Available Funds Cap Reserve Fund shall be for the benefit of the Class A-X Certificateholders. The Class A-X Certificates shall evidence ownership of the Available Funds Cap Reserve Fund for federal income tax purposes and the Class A-X Certificateholders shall direct the Securities Administrator, in writing, as to investment of amounts on deposit therein. The Class A-X Certificateholders shall be liable for any losses incurred on such investments. In the absence of written instructions from a majority of the Class A-X Certificateholders as to investment of funds on deposit in the Available Funds Cap Reserve Fund, such funds shall be invested in money market funds as described in clause (viii) of the definition of Eligible Investments in Article I. For all Federal income tax purposes, amounts transferred by the Upper Tier REMIC to the Available Funds Cap Reserve Fund shall be treated as amounts distributed by the Upper Tier REMIC to the Class A-X Certificateholders.

(g) Upon termination of the Trust Fund, any amounts remaining in the Available Funds Cap Reserve Fund shall be distributed to the Class A-X Certificateholders.

Section 5.07. Yield Maintenance Account.

Any Yield Maintenance Amounts received by the Securities Administrator pursuant to the Yield Maintenance Agreements in connection with each such Distribution Date shall be deposited into the Yield Maintenance Account. On each Distribution Date, the Securities Administrator on behalf of the Trust shall distribute amounts on deposit in the Yield Maintenance Account in the following order of priority:

(e) It is the intention of the parties hereto that, for federal and state income and state and local franchise tax purposes, the Final Maturity Reserve Trust be disregarded as an entity separate from the holder of the Class I Certificates unless and until the date when either (a) there is more than one Class I Certificateholder or (b) any Class of Certificates in addition to the Class I Certificates is recharacterized as an equity interest in the Final Maturity Reserve Trust for federal income tax purposes. Neither the Securities Administrator nor the Trustee shall be responsible for any entity level tax reporting for the Final Maturity Reserve Trust.

(f) For federal income tax purposes, any Certificateholder that receives a principal payment from the Final Maturity Reserve Trust shall be treated as selling a portion of its Certificate to the Class I Certificateholder and as having received the amount of the principal payment from the Class I Certificateholder as the proceeds of the sale. The portion of the Certificate that is treated as having been sold shall equal the amount of the corresponding reduction in the Certificate Principal Amount of such Certificate. Principal payments received from the Final Maturity Reserve Trust shall not be treated as distributions from any REMIC created hereby.

The reasonable expense thereof shall be paid by the Holders requesting such investigation;

(v)

Each of the Trustee and the Securities Administrator may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, accountants or attorneys, which agents, custodians, accountants or attorneys shall have any and all of the rights, powers, duties and obligations of such party conferred on them by such appointment provided that such party shall continue to be responsible for its duties and obligations hereunder to the extent provided herein, and provided further that such party shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by such party;

Neither the Trustee nor the Securities Administrator makes any representations as to the validity or sufficiency of this Agreement or of the Certificates (other than in the case of the Securities Administrator, the certificate of authentication on the Certificates), the Auction Administration Agreement, the Auction Swap Agreement, the Yield Maintenance Agreements or of any Mortgage Loan, or related document save that each of the Trustee and the Securities Administrator represents as to itself that, assuming due execution and delivery by the other parties hereto, this Agreement has been duly authorized, executed and delivered by it and constitutes its valid and binding obligation, enforceable against it in accordance with its terms except that 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. Neither the Trustee nor the Securities Administrator shall be accountable for the use or application by the Depositor of funds paid to the Depositor in consideration of the assignment of the Mortgage Loans to the Trust Fund by the Depositor or for the use or application of any funds deposited into the Collection Account, the Certificate Account, any Escrow Account or any other fund or account maintained with respect to the Certificates.

Each of the Trustee, the Custodian, the Delaware Trustee, the Master Servicer and the Securities Administrator and any Affiliate thereof, in its individual or any other capacity may become the owner or pledged of Certificates and may transact banking and trust business with the other parties hereto with the same rights it would have if it were not Trustee, the Custodian, the Delaware Trustee, the Master Servicer and the Securities Administrator or such agent, as applicable.

Section 6.05. Eligibility Requirements for Trustee, Delaware Trustee and Securities Administrator; Insurance.

The Trustee and any successor Trustee and the Securities Administrator and any successor Securities Administrator shall during the entire duration of this Agreement be a state bank or trust company or a national banking association organized and doing business under the laws of such state or the United States of America, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus and undivided profits of at least $40,000,000 or, in the case of a successor Trustee, $50,000,000, subject to supervision or examination by federal or state authority and, in the case of the Trustee, rated “Baa2,” “BBB” or its equivalent or higher by the Rating Agencies with respect to any outstanding long-term unsecured unsubordinated debt, and, in the case of a successor Trustee or successor Securities Administrator other than pursuant to Section 6.08, rated in one of the two highest long-term debt categories of, or otherwise acceptable to, the Rating Agencies. If the Trustee publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its total equity capital (combined capital and surplus) as set forth in its most recent report of condition so published. With respect to the Securities Administrator, it (i) may not be an originator, master servicer, or Servicer, unless it is in an institutional trust department of its parent; (ii) must be authorized to exercise trust powers under the laws of its jurisdiction of organization and (iii) must be rated at least "A/F1" by Fitch, if Fitch provides a rating with respect to the Securities Administrator at the time of determination of such rating, or the equivalent rating by S&P or Moody's. The Trustee shall notify the Rating Agencies of any change of Securities Administrator. In case at any time the Trustee or the Securities Administrator shall cease to be eligible in accordance with the provisions of this Section, the Trustee or the Securities Administrator shall resign immediately in the manner and with the effect specified in Section 6.06.

The Delaware Trustee shall at all times be a trustee eligible to serve in such capacity pursuant to the provisions of the DSTS. There shall at all times be a Delaware trustee of the Trust, and in the event, that the Delaware Trustee no longer serves as the Delaware trustee, the Trustee shall be responsible for the appointment of a successor Delaware trustee.

The Trustee, at its own expense, shall at all times maintain and keep in full force and effect: (i) fidelity insurance, (ii) theft of documents insurance and (iii) forgery insurance (which may be collectively satisfied by a “Financial Institution Bond” and/or a “Bankers’ Blanket Bond”). All such insurance shall be in amounts, with standard coverage and subject to deductibles, as are customary for insurance typically maintained by banks or their affiliates which act as custodians for investor-owned mortgage pools. A certificate of an officer of the Trustee as to the Trustee’s compliance with this Section shall be furnished to any Certificateholder upon reasonable written request.

Section 6.06. Resignation and Removal of Trustee and Securities Administrator.

(a)

Each of the Trustee and the Securities Administrator may at any time resign and be discharged from the trust hereby created by giving written notice thereof to the other party and to the Depositor and the Master Servicer, with a copy to the Rating Agencies. Upon receiving such notice of resignation, the Seller shall promptly appoint a successor trustee or successor securities administrator, as applicable, that meets the requirements in Section 6.05, in each case, by written instrument, one copy of which instrument shall be delivered to the resigning Trustee or Securities Administrator, as applicable, one copy to the successor trustee or successor securities administrator, as applicable, and one copy to the Master Servicer. If no successor trustee shall have been so appointed and shall have accepted appointment within 60 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor. If no successor securities administrator shall have been so appointed and shall have accepted appointment within 60 days after the giving of such notice of resignation, the Trustee shall become the successor securities administrator or, notwithstanding the above, the Trustee may, if it shall be unwilling so to act, or shall, if it is legally unable so to act, appoint a successor securities administrator meeting the requirements of Section 6.05 to assume all or any part of the responsibilities, duties or liabilities of the Securities Administrator hereunder; provided, that the Trustee shall obtain a letter from each Rating Agency that the rating provided by such Rating Agency, if any, on each of the Certificates will not be lowered as a result of the selection of the successor to the Securities Administrator and such successor securities administrator shall be reasonably acceptable to ▇▇▇▇▇▇▇▇▇. Pending appointment by the Trustee of a successor to the Securities Administrator hereunder, the Trustee shall act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on the Mortgage Loans as it and such successor shall agree; provided, however, no such compensation shall be in excess of that permitted the Securities Administrator, except that Section 9.28 shall apply to the same extent it applies to a successor Master Servicer. Such successor shall undertake and assume the obligations of the Trustee to pay compensation to any third Person acting as an agent or independent contractor in the performance of the securities administrator responsibilities hereunder. If the Trustee shall succeed to any duties of the Securities Administrator respecting the Mortgage Loans as provided herein, it shall do so in a separate capacity and not in its capacity as Trustee. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

(b)

If at any time (i) either the Trustee or the Securities Administrator shall cease to be eligible in accordance with the provisions of Section 6.05 and shall fail to resign after written request therefor by the Seller, (ii) the Trustee or the Securities Administrator shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or the Securities Administrator or of its property shall be appointed, or any public officer shall take charge or control of such party or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, (iii) a tax is imposed or threatened with respect to the Trust Fund by any state in which the Trustee, the Securities Administrator or the Trust Fund is located, or (iv) the continued use of the Trustee or the Securities Administrator would result in a downgrading of the rating by the Rating Agencies of any Class of Certificates with a rating, then the Seller shall remove the Trustee or the Securities Administrator, as applicable, and appoint a successor trustee or securities administrator by written instrument, one copy of which instrument shall be delivered to the Trustee or Securities Administrator so removed, one copy to the successor and one copy to the Master Servicer. To the extent a successor of either the Trustee or the Securities Administrator is not so appointed within 60 days, the procedure set forth in Section 6.06(a) shall be followed with respect to each successor.

(c)

The Holders of more than 50% of the Aggregate Voting Interests of each Class of Certificates may at any time upon 30 days’ written notice to the Trustee, the Securities Administrator and the Depositor remove the Trustee or the Securities Administrator by such written instrument, signed by such Holders or their attorney-in-fact duly authorized, one copy of which instrument shall be delivered to the Depositor, one copy to the Trustee or Securities Administrator so removed and one copy to the Master Servicer; the Depositor shall thereupon use its best efforts to appoint a mutually acceptable successor in accordance with this Section.

(d)

Any resignation or removal of the Trustee or the Securities Administrator and appointment of a successor pursuant to any of the provisions of this Section shall become effective upon acceptance of appointment by the successor as provided in Section 6.07. If ▇▇▇▇▇ Fargo Bank, N.A. resigns or is removed as Securities Administrator, it shall resign (or in the case of removal, be deemed removed) as Master Servicer.

Section 6.07. Successor Trustee or Successor Securities Administrator.

(a)

Any successor trustee or securities administrator appointed as provided in Section 6.06 shall execute, acknowledge and deliver to the Depositor, the Seller, the Master Servicer and to its predecessor an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor shall become effective and such successor, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee or securities administrator, as applicable, herein. The predecessor trustee shall deliver to the successor trustee all Mortgage Files and documents and statements related to all Mortgage Files held by it hereunder, and shall duly assign, transfer, deliver and pay over to the successor trustee the entire Trust Fund, together with all necessary instruments of transfer and assignment or other documents properly executed necessary to effect such transfer and such of the record or copies thereof maintained by the predecessor trustee in the administration hereof as may be requested by the successor trustee and shall thereupon be discharged from all duties and responsibilities under this Agreement. In addition, the Master Servicer and the predecessor trustee or securities administrator, as applicable, shall execute and deliver such other instruments and do such other things as may reasonably be required to more fully and certainly vest and confirm in the successor all such rights, powers, duties and obligations.

(b)

No successor trustee or securities administrator shall accept appointment as provided in this Section unless at the time of such appointment such successor shall be eligible under the provisions of Section 6.05.

(c)

Upon acceptance of appointment by a successor trustee or securities administrator, as applicable, as provided in this Section, the Master Servicer shall mail notice of the succession of such trustee hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register and to the Rating Agencies. The expenses of such mailing shall be borne by the Master Servicer.

Section 6.08. Merger or Consolidation of Trustee or Securities Administrator.

Any Person into which the Trustee or the Securities Administrator may be merged or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee or the Securities Administrator shall be a party, or any Persons succeeding to the corporate trust business of the Trustee or the Securities Administrator, shall be the successor to such party hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding, provided that such Person shall be eligible under the provisions of Section 6.05.

Section 6.09. Appointment of Co-Trustee, Separate Trustee or Custodian.

(a)

Notwithstanding any other provisions hereof and in addition to the appointment of the Delaware Trustee pursuant to Section 1.03(c) hereof, at any time, the Trustee, the Depositor or the Certificateholders evidencing more than 50% of the Aggregate Voting Interests shall each have the power from time to time to appoint one or more Persons approved by the Trustee (such approval not to be unreasonably withheld) to act either as co-trustees jointly with the Trustee, or as separate trustees, or as custodians, for the purpose of holding title to, foreclosing or otherwise taking action with respect to any Mortgage Loan outside the state where the Trustee has its principal place of business where such separate trustee or co-trustee is necessary or advisable (or the Trustee has been advised by the Master Servicer that such separate trustee or co-trustee is necessary or advisable) under the laws of any state in which a property securing a Mortgage Loan is located or for the purpose of otherwise conforming to any legal requirement, restriction or condition in any state in which a property securing a Mortgage Loan is located or in any state in which any portion of the Trust Fund is located. The separate Trustees, co-trustees, or custodians so appointed shall be trustees or custodians for the benefit of all the Certificateholders and shall have such powers, rights and remedies as shall be specified in the instrument of appointment; provided, however, that no such appointment shall, or shall be deemed to, constitute the appointee an agent of the Trustee. The obligation of the Trustee to make Advances pursuant to Section 5.04 and Section 6.14 hereof shall not be affected or assigned by the appointment of a co-trustee.

(b)

Every separate trustee, co-trustee, and custodian shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i)

all powers, duties, obligations and rights conferred upon the Trustee in respect of the receipt, custody and payment of moneys shall be exercised solely by the Trustee;

(ii)

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

(iii)

no trustee or custodian hereunder shall be liable by reason of any act or omission of any other trustee or custodian hereunder and such appointment shall not, and shall not be deemed to, constitute any such separate trustee or co-trustee as agent of the Trustee; and

(iv)

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

(c)

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

(d)

Any separate trustee, co-trustee or custodian may, at any time, constitute the Trustee its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name.

If any separate trustee, co-trustee or custodian shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

(e)

(g)

The Trustee shall pay the reasonable compensation of the co-trustees to the extent, and in accordance with the standards, specified in Section 6.12 hereof (which compensation shall not reduce any compensation payable to the Trustee under such Section).

Section 6.10. Authenticating Agents.

(a)

The Securities Administrator may appoint one or more Authenticating Agents which shall be authorized to act on behalf of the Securities Administrator in authenticating Certificates. Wherever reference is made in this Agreement to the authentication of Certificates by the Securities Administrator or the Securities Administrator’s certificate of authentication, such reference shall be deemed to include authentication on behalf of the Securities Administrator by an Authenticating Agent and a certificate of authentication executed on behalf of the Securities Administrator by an Authenticating Agent. Each Authenticating Agent must be a corporation organized and doing business under the laws of the United States of America or of any state, having a combined capital and surplus of at least $15,000,000, authorized under such laws to do a trust business and subject to supervision or examination by federal or state authorities.

(b)

Any Person into which any Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which any Authenticating Agent shall be a party, or any Person succeeding to the corporate agency business of any Authenticating Agent, shall continue to be the Authenticating Agent without the execution or filing of any paper or any further act on the part of the Securities Administrator or the Authenticating Agent.

The Securities Administrator may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and the Depositor. Upon receiving a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.10, the Securities Administrator may appoint a successor Authenticating Agent, shall give written notice of such appointment to the Depositor and shall mail notice of such appointment to all Holders of Certificates. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named as Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 6.10. No Authenticating Agent shall have responsibility or liability for any action taken by it as such at the direction of the Securities Administrator. Any Authenticating Agent compensation shall be paid by the Securities Administrator.

Section 6.11. Indemnification of Trustee, the Custodian, the Delaware Trustee and Securities Administrator.

The Trustee, the Custodian, the Delaware Trustee and the Securities Administrator and its directors, officers, employees and agents shall be entitled to indemnification from the Trust Fund for any loss, liability or expense incurred (including, without limitation, the fees and expenses of its counsel and agents) without negligence or willful misconduct on their part, arising out of, or in connection with, the acceptance or administration of the trusts created hereunder or in connection with the performance of the its duties hereunder or under the Auction Administration Agreement, Auction Swap Agreement, Yield Maintenance Agreements, Mortgage Loan Purchase Agreement or any Servicing Agreement, including any applicable fees and expenses payable pursuant to Section 6.12 and the costs and expenses of defending themselves against any claim in connection with the exercise or performance of any of their powers or duties hereunder, provided that:

(i)

with respect to any such claim, the Trustee, the Custodian, the Delaware Trustee or the Securities Administrator shall have given the Depositor, the Master Servicer and the Holders written notice thereof promptly after such party shall have knowledge thereof; provided, however, that failure to notify shall not relieve the Trust of its obligations to indemnify the Trustee, the Delaware Trustee or the Securities Administrator under this Section 6.11;

(ii)

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

(iii)

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

provided, however that clauses (ii) and (iii) shall not apply if the Trustee’s, the Custodian’s, the Delaware Trustee’s or the Securities Administrator’s position is materially adverse to that of the Depositor. The provisions of this Section 6.11 shall survive any termination of this Agreement and the resignation or removal of the Trustee, the Delaware Trustee and the Securities Administrator and shall be construed to include, but not be limited to any loss, liability or expense under any environmental law.

Section 6.12. Fees and Expenses of Trustee, Securities Administrator and Delaware Trustee.

The Trustee, as compensation for all services rendered by the Trustee in the exercise and performance of any of the powers and duties hereunder, shall be entitled to receive from the Certificate Account on each Distribution Date an amount equal to the Trustee Fee for such Distribution Date. The Delaware Trustee shall be compensated by the Seller for its services hereunder. The Securities Administrator shall be compensated by the Master Servicer for its services hereunder from a portion of the Master Servicing Fee Rate. In addition, the Trustee, the Delaware Trustee and the Securities Administrator will be entitled to recover from the Certificate Account pursuant to Section 4.02 all reasonable out-of-pocket expenses, disbursements and advances and the expenses of the Trustee (including for such purpose, any fees and expenses relating to its capacity as Custodian hereunder to the extent not paid by ▇▇▇▇▇▇▇▇▇), the Delaware Trustee, and the Securities Administrator, respectively, including without limitation, in connection with any Event of Default, any breach of this Agreement or any claim or legal action (including any pending or threatened claim or legal action) incurred or made by the Delaware Trustee, the Trustee or the Securities Administrator, respectively, in the performance of its duties or the administration of the trusts hereunder (including the reasonable compensation, expenses and disbursements of its counsel) except any such expense, disbursement or advance as may arise from its negligence (or in the case of the Delaware Trustee, gross negligence) or intentional misconduct or which is specifically designated herein as the responsibility of the Depositor, the Seller, the Master Servicer, the Certificateholders, the Delaware Trustee, the Securities Administrator or the Trust hereunder. If funds in the Distribution Account are insufficient therefor, the Trustee, the Delaware Trustee, the Custodian and the Securities Administrator shall recover such expenses from future collections on the Mortgage Loans or as otherwise agreed by the Certificateholders. Such compensation and reimbursement obligation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust.

Section 6.13. Collection of Monies.

Except as otherwise expressly provided in this Agreement, the Securities Administrator may demand payment or delivery of, and shall receive and collect, all money and other property payable to or receivable by the Securities Administrator pursuant to this Agreement. The Securities Administrator shall hold all such money and property received by it as part of the Trust Fund or the Final Maturity Reserve Trust and shall distribute it as provided in this Agreement. If the Securities Administrator shall not have timely received amounts to be remitted with respect to the Mortgage Loans from the Master Servicer, the Securities Administrator shall request the Master Servicer to make such distribution as promptly as practicable or legally permitted. If the Securities Administrator shall subsequently receive any such amount, it may withdraw such request.

(iii)

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

(iv)

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

(v)

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

(vi)

If a representation or warranty set forth in Section 9.14 hereof shall prove to be incorrect as of the time made in any respect that materially and adversely affects the interests of the Certificateholders, and the circumstance or condition in respect of which such representation or warranty was incorrect shall not have been eliminated or cured within 60 days after the date on which written notice of such incorrect representation or warranty shall have been given to the Master Servicer by the Trustee, or to the Master Servicer and the Trustee by the Holders of not less than 25% of the Aggregate Voting Interests; or

(vii)

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

If an Event of Default described in clauses (i) through (ix) of this Section 6.14 shall occur, then, in each and every case, subject to applicable law, so long as any such Event of Default shall not have been remedied within any period of time prescribed by this Section 6.14, the Trustee, by notice in writing to the Master Servicer may, and shall, if so directed by Certificateholders evidencing more than 50% of the Aggregate Voting Interests, terminate all of the rights and obligations of the Master Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof.

The Master Servicer being terminated shall bear its costs of a master servicing transfer and the reasonable out-of-pocket fees and expenses of the Trustee associated with such master servicing transfer. To the extent that such costs and expenses of the Trustee are not fully and timely reimbursed by the predecessor Master Servicer, the Trustee shall be entitled to reimbursement of such costs and expenses from the Distribution Account within sixty (60) days.

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

Upon the receipt by the Master Servicer of a notice of termination pursuant to Section 6.14(a) or an Opinion of Counsel pursuant to Section 9.28 to the effect that the Master Servicer is legally unable to act or to delegate its duties to a Person which is legally able to act, the Trustee shall automatically become the successor in all respects to the Master Servicer in its capacity under this Agreement and the transactions set forth or provided for herein and shall thereafter be subject to all the responsibilities, duties, liabilities and limitations on liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof; provided, however, that the Trustee shall have no obligation whatsoever with respect to any liability (other than Advances deemed recoverable and not previously made by the Master Servicer, which shall be made by the Trustee in its place and stead) incurred by the Master Servicer at or prior to the time of termination. As compensation therefor, but subject to Section 9.28, the Trustee shall be entitled to all funds relating to the Mortgage Loans which the Master Servicer would have been entitled to retain if the Master Servicer had continued to act hereunder, except for those amounts due the Master Servicer as reimbursement permitted under this Agreement for advances previously made or expenses previously incurred.

(c)

Notwithstanding the above, the Trustee may, if it shall be unwilling so to act, or shall, if it is legally unable so to act, appoint or petition a court of competent jurisdiction to appoint, any established housing and home finance institution which is a ▇▇▇▇▇▇ ▇▇▇- or ▇▇▇▇▇▇▇ Mac-approved servicer, and with respect to a successor to the Master Servicer only, having a net worth of not less than $10,000,000, as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder; provided, that the Trustee shall obtain a letter from each Rating Agency that the rating provided by such Rating Agency, if any, on each of the Certificates will not be lowered as a result of the selection of the successor to the Master Servicer and such successor Master Servicer shall be reasonably acceptable to ▇▇▇▇▇▇▇▇▇ in the event that ▇▇▇▇▇▇▇▇▇ does not choose to become the Master Servicer pursuant to Section 8.02(d). Pending appointment of a successor to the Master Servicer hereunder, the Trustee shall act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on the Mortgage Loans as it and such successor shall agree; provided, however, except as provided in Section 9.28, no such compensation shall be in excess of that permitted the Trustee under this Subsection, and that such successor shall undertake and assume the obligations of the Trustee to pay compensation to any third Person acting as an agent or independent contractor in the performance of master servicing responsibilities hereunder. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

(d)

If the Trustee shall succeed to any duties of the Master Servicer respecting the Mortgage Loans as provided herein, it shall do so in a separate capacity and not in its capacity as Trustee and, accordingly, the provisions of Article IX shall be inapplicable to the Trustee in its duties as the successor to the Master Servicer in the servicing of the Mortgage Loans (although such provisions shall continue to apply to the Trustee in its capacity as Trustee); the provisions of Article IX, however, shall apply to it in its capacity as successor master servicer. In the event that the Trustee shall not succeed to the duties of the Master Servicer pursuant to Section 6.14(b) hereof, ▇▇▇▇▇▇▇▇▇ shall have the right, but not the obligation, to be appointed successor master servicer hereunder.

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

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

Section 6.16. Waiver of Defaults.

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

Section 6.17. Notification to Holders.

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

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

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

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

In the event that a Responsible Officer of the Trustee shall have actual knowledge of any action or inaction of the Master Servicer that would become an Event of Default upon the Master Servicer’s failure to remedy the same after notice, the Trustee shall give notice thereof to the Master Servicer.

Section 6.20. Auction Administration Agreement; Auction Swap Agreement.

(a)

Concurrently with the execution and delivery hereof, at the direction of the Depositor, the Securities Administrator, acting solely as an agent (the “Auction Administrator”) for the Holders of the Auction Certificates and not on behalf of the Trust, shall execute and deliver the Auction Administration Agreement and the Auction Swap Agreement in the forms presented by the Auction Swap Counterparty provided that the provisions of Section 1.07 remain applicable to each Certificateholder. The Securities Administrator shall have no duty to review or otherwise determine the adequacy of the Auction Administration Agreement or the Auction Swap Agreement.

(b)

Each Holder of an Auction Certificate is deemed, by acceptance of such Certificate, (i) to authorize the Securities Administrator to execute and deliver the Auction Administration Agreement and the Auction Swap Agreement as their agent and (ii) to acknowledge and accept and agree to be bound by the provisions of the Auction Administration Agreement and the Auction Swap Agreement. The Securities Administrator, as Auction Administrator, agrees not to consent to any amendments to the Auction Administration Agreement or Auction Swap Agreement without the consent of 100% of the Auction Certificates.

ARTICLE VII

PURCHASE AND TERMINATION
OF THE TRUST FUND

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

(a)

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

(b)

On any Distribution Date following the month in which the aggregate Scheduled Principal Balance of the Mortgage Loans is equal to or less than 10% of the Cut-off Date Aggregate Scheduled Principal Balance, the Seller in its capacity as a Servicer may, upon written direction to the Trustee (with a copy to the Securities Administrator) no later than twenty (20) Business Days prior to such Distribution Date, cause (i) the Trustee to sell to it (or arrange for the sale of) the assets of the Trust Fund and (ii) the Trust Fund to adopt a plan of complete liquidation pursuant to Section 7.03 hereof to sell all of its property. The property of the Trust Fund shall be sold at a price (the “Termination Price”) equal to: (i) 100% of the unpaid principal balance of each Mortgage Loan on the Distribution Date such purchase occurs plus interest accrued thereon at the applicable Mortgage Rate with respect to any Mortgage Loan to the Due Date in the Due Period immediately preceding the final Distribution Date, (ii) the fair market value of any REO Property and any other property held by the Trust Fund, such fair market value to be determined by an appraiser or appraisers appointed by the Master Servicer with the consent of the Trustee, (iii) any unreimbursed Servicing Advances with respect to each Mortgage Loan and (iv) any Advances to the extent not covered in (i), advances and other amounts then due and owing to the Master Servicer, any Servicer, the Securities Administrator, the Trustee and the Delaware Trustee under this Agreement.

Section 7.02. Procedure Upon Termination of Trust Fund.

(a)

Notice of any termination pursuant to the provisions of Section 7.01, specifying the Distribution Date upon which the final distribution shall be made, shall be given promptly by the Securities Administrator by first class mail to Certificateholders mailed no later than ten (10) Business Days prior to the final Distribution Date. Such notice shall specify (A) the Distribution Date upon which final distribution on the Certificates of all amounts required to be distributed to Certificateholders pursuant to Section 5.02 will be made upon presentation and surrender of the Certificates at the office or agency of the Securities Administrator, 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. The Securities Administrator shall give such notice to the Depositor, the Trustee, the Master Servicer and the Certificate Registrar at the time such notice is given to Holders of the Certificates. Upon any such termination, the duties of the Certificate Registrar with respect to the Certificates shall terminate and the Securities Administrator shall terminate, or request the Master Servicer to terminate, the Collection Account it maintains, the Certificate Account and any other account or fund maintained with respect to the Certificates, subject to the Securities Administrator’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment.

(b)

In the event that all of the Holders do not surrender their Certificates for cancellation within three months after the time specified in the above-mentioned written notice, the 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 Certificate holder’s failure to surrender its Certificate(s) for payment of the final distribution thereon in accordance with this Section.

(c)

The Seller, in its capacity as a Servicer, shall reimburse the Securities Administrator for any reasonable expenses incurred by the Securities Administrator in connection with any termination or liquidation of the Trust Fund.

Section 7.03. Additional Requirements under the REMIC Provisions.

(a)

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

(i)

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

(ii)

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

(b)

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

(c)

Upon the termination or liquidation of the REMICs, the Delaware Trustee shall file a certificate of cancellation with the Delaware Secretary of State in accordance with Section 3810(d) of the DSTS, and the Trust’s existence shall be terminated.

Section 7.04. Optional and Required Purchases of Certain Mortgage Loans.

(a)

▇▇▇▇▇▇▇▇▇, in its capacity as a Servicer of a substantial portion of the Mortgage Loans, shall have the right to purchase from the Trust any Mortgage Loan which as of the first day of a calendar quarter is delinquent in payment by 90 days or more or is an REO Property, at a price equal to the Purchase Price; provided however (i) that such Mortgage Loan is still 90 days or more delinquent or is an REO Property as of the date of such purchase and (ii) this purchase option, if not theretofore exercised, shall terminate on the date prior to the last day of the related calendar quarter. This purchase option, if not exercised, shall not be thereafter reinstated unless the delinquency is cured and the Mortgage Loan thereafter again becomes 90 days or more delinquent or becomes an REO Property, in which case the option shall again become exercisable as of the first day of the related calendar quarter.

(b)

In addition, ▇▇▇▇▇▇▇▇▇, in its capacity as the Seller, may, but is not required to, repurchase any Mortgage Loan as to which the Mortgagor has requested a Significant Modification and such Mortgagor has a satisfactory payment history under such Mortgage Loan and meets the credit standards of the Seller for the loan program selected (a “Significant Modification Loan”). A “Significant Modification” shall mean any modification to the interest rate of the greater of (i) 0.25% added or subtracted from the existing rate and (ii) a change equal to the product of (a) 5% and (b) the annual existing interest rate thereon, which is not provided for in the related Mortgage Note. If ▇▇▇▇▇▇▇▇▇ grants any request for a Significant Modification, it shall be required to repurchase any such Mortgage Loan prior to making such Significant Modification. The purchase price for any repurchase pursuant to this Section 7.04(b) shall be the applicable Purchase Price. In order to exercise its repurchase rights hereunder, the Seller shall deliver to the Master Servicer and the Trustee an Officer’s Certificate identifying the Mortgage Loan to be repurchased and certifying that (i) such Mortgage Loan is a Significant Modification Loan, and (ii) that the Significant Modification Loan will be entered into on the date of such repurchase.

(c)

No later than the fourth Business Day prior to each Distribution Date, ▇▇▇▇▇▇▇▇▇ will provide to the Master Servicer a list identifying all Mortgage Loans that became Converted Mortgage Loans or Modified Mortgage Loans during the related Due Period. On the third Business Day prior to each Distribution Date, provided that it has received such list from ▇▇▇▇▇▇▇▇▇, the Master Servicer shall prepare and provide to TMI a Converted Mortgage Loan Schedule and a Modified Mortgage Loan Schedule with respect to such Due Period. No later than 1:00 PM Eastern Time on the second Business Day prior to each Distribution Date, TMI shall purchase each Converted Mortgage Loan and Modified Mortgage Loan, to the extent specified in a Converted Mortgage Loan Schedule or Modified Mortgage Loan Schedule delivered to it by the Master Servicer for such Distribution Date, at the applicable Purchase Price for each such Converted Mortgage Loan or Modified Mortgage Loan, as applicable, and shall remit such Purchase Price to the Master Servicer for deposit in the Collection Account.

(d)

If at any time ▇▇▇▇▇▇▇▇▇ or TMI, as applicable, remits to the Master Servicer a payment for deposit in the Collection Account covering the amount of the Purchase Price for a Mortgage Loan of the type set forth in clauses (a), (b) or (c) above, as applicable, and ▇▇▇▇▇▇▇▇▇, or TMI, as applicable, provides to the Trustee a certification signed by a Servicing Officer stating that the amount of such payment has been deposited in the Collection Account, then the Trustee, on behalf of the Trust, shall execute the assignment of such Mortgage Loan at the request of ▇▇▇▇▇▇▇▇▇ or TMI without recourse to, or representation or warranty by, the Trustee or the Trust and delivered to ▇▇▇▇▇▇▇▇▇ or TMI, as applicable, which shall succeed to all the Trust’s and/or the Trustee’s right, title and interest in and to such Mortgage Loan, and all security and documents relative thereto. Such assignment shall be an assignment outright and not for security. ▇▇▇▇▇▇▇▇▇ or TMI, as applicable, will thereupon own such Mortgage Loan, and all such security and documents, free of any further obligation to the Trust, the Trustee or the Certificateholders with respect thereto.

Section 7.05. Optional Purchase of Certificates.

(a)

All but not less than all of the Certificates are subject to purchase by TMI, at its option, on any Distribution Date on or after the Optional Securities Purchase Date from the then Certificateholders thereof; provided, however, that TMI may appoint a designee to purchase the Residual Certificate. The purchase price for each Certificate (other than a Class A-X or Class R Certificate) shall be equal to the sum of (i) the Certificate Principal Amount of such Certificate and (ii) any accrued but unpaid interest thereon at the applicable Certificate Interest Rate with respect thereto for such Distribution Date. The purchase price for the Class A-X Certificates shall be an amount equal to the sum of (x) any Accrued Certificate Interest and Interest Shortfall due (after taking into account payments made on such date for Accrued Certificate Interest and Interest Shortfall for each Mortgage Pool and any amount required to be deposited in the Available Funds Cap Reserve Fund in respect of the Class A-X Certificates) on the Class A-X Certificates and (y) the present value, as of the date of such termination, of the remaining payments scheduled to be made on the Class A-X Certificates (such present value to be based on a discount rate that will approximate the expected yield to maturity of the Class A-X Certificates). The purchase price for the Class R Certificate shall be $1.00. The purchase price for the Class I Certificate shall be $1.00. In order to exercise the Optional Securities Purchase Right, TMI must, no later than the eighth Business Day prior to the applicable Distribution Date, deliver to the Trustee and the Securities Administrator (with copies to the Rating Agencies and the Master Servicer) written notice of its intent to purchase the Certificates and of the Distribution Date on which it intends to do so and the Securities Administrator will verify in writing to TMI and the Trustee the cash amount required of TMI to effect such purchase no later than the third Business Day prior to the Distribution Date on which such purchase is scheduled to occur. The Securities Administrator shall furnish notice of the exercise of the Optional Securities Purchase Right to the applicable Certificateholders in compliance with Section 7.05(c). On the Distribution Date on which the Optional Securities Purchase Right will be exercised, TMI shall deposit the appropriate amount in cash with the Securities Administrator. Such amount shall be deposited by the Securities Administrator into a separate sub-account of the Distribution Account (the “Purchase Account”). Such amounts shall be paid by the Securities Administrator to Holders of the applicable Certificates as provided in Section 7.05(d).

(b)

In the case of an exercise of the Optional Securities Purchase Right, TMI shall be solely responsible for the costs and expenses of the Securities Administrator, the Trustee and the Master Servicer.

(c)

Notice of exercise of the Optional Securities Purchase Right under Section 7.05(a) shall be given by the Securities Administrator by facsimile or by first-class mail, postage prepaid, transmitted or mailed not less than five Business Days prior to the applicable Distribution Date, to the Holder of the Class R Certificate as of the close of business on the Record Date preceding such Distribution Date and to each Holder of a Certificate (other than a Residual Certificate) as of a date not more than one Business Day preceding the mailing of such notice, at such Holder's address appearing in the Certificate Register.

All such notices shall state:

(i)

the Distribution Date upon which the Certificateholders will receive payment in full on the applicable Certificates;

(ii)

the amount the applicable Certificateholders will be paid, separately stating amounts in respect of principal and interest;

(iii)

that the Record Date otherwise applicable to such Distribution Date is not applicable and that payments shall be made only upon presentation and surrender of the respective Certificates and the place where such Certificates are to be surrendered for payment; and

(iv)

that interest on the respective Certificates shall cease to accrue for the benefit of the then Certificateholders on such Distribution Date and no interest shall accrue on the price paid for such Certificates.

The foregoing notice shall be given by the Securities Administrator in the name and at the expense of TMI. Failure to give notice of such purchase, or any defect therein, to any Holder of any Certificate shall not impair or affect the validity of the purchase of any other Certificate.

(d)

The Certificates shall, following notice as required by Section 7.05(c), be purchased on the applicable Distribution Date by TMI at the price specified in Section 7.05(a) from funds in the Purchase Account, and (unless TMI shall default in the payment of such amount) no interest shall accrue on such amount for any period after the date to which accrued interest is calculated for purposes of calculating such amount.

(e)

Subsequent to the purchase of the Certificates following exercise of the Optional Securities Purchase Right, TMI shall be the sole Holder of the Certificates (other than the Residual Certificates) and it shall either be the sole Holder of the Class R Certificate or may designate a Person which meets the requirements of this Agreement to become the Holder thereof. TMI may subsequently transfer some or all of the Certificates acquired by it in accordance with the provisions hereof. All Certificates issued to the Certificateholders prior to exercise of the Optional Securities Purchase Right shall be deemed cancelled.

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 Aggregate Voting Interests shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the cost, expenses and liabilities to be incurred therein or thereby, and the Trustee, for sixty days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request has been given such Trustee during such sixty-day period by such Certificateholders; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Agreement, except in the manner herein provided and for the benefit of all Certificateholders. 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 Trustee, and such application states that the Applicants desire to communicate with other Holders with respect to their rights under this Agreement or under the Certificates and is accompanied by a copy of the communication which such Applicants propose to transmit, then the 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 the most recent list of Certificateholders held by the Certificate Registrar or shall, as an alternative, send, at the Applicants’ expense, the written communication proffered by the Applicants to all Certificateholders at their addresses as they appear in the Certificate Register.

(c)

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

Section 8.03. Acts of Holders of Certificates.

(a)

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

(b)

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

(c)

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

(d)

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

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS
BY THE MASTER SERVICER

Section 9.01. Duties of the Master Servicer.

The Certificateholders, by their purchase and acceptance of the Certificates, appoint ▇▇▇▇▇ 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 the applicable Servicing Agreements. Notwithstanding anything in this Agreement or any Servicing Agreement to the contrary, the Master Servicer shall have no duty or obligation to enforce, supervise, monitor or oversee the activities of any Servicer (i) with respect to its servicing of any Additional Collateral or (ii) with respect to any action taken or not taken by a Servicer at the direction of the Seller.

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 fidelity bond and an 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 errors and omissions insurance policy and the 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 shall by its terms not be cancelable without thirty days’ prior written notice to the Trustee; the Master Servicer shall provide the Trustee, upon request therefor, a copy of such policy and fidelity bond. The Master Servicer shall, in accordance with each applicable Servicing Agreement, (i) require each Servicer to maintain an Errors and Omissions Insurance Policy and a Fidelity Bond, (ii) cause each Servicer to provide to the Master Servicer certificates evidencing that such policy and bond is in effect and to furnish to the Master Servicer any notice of cancellation, non-renewal or modification of the policy or bond received by it, and (iii) furnish copies of such policies and of the certificates and notices referred to in clause (ii) to the Trustee upon its request.

(b)

The Master Servicer shall promptly report to the Trustee any material changes that may occur in the fidelity bond or the errors and omissions insurance policy required to be maintained by it and shall furnish to the Trustee, on request, certificates evidencing that such bond and insurance policy are in full force and effect. The Master Servicer shall promptly report to the Trustee all cases of embezzlement or fraud, if such events involve funds relating to the Mortgage Loans. The total losses, regardless of whether claims are filed with the applicable insurer or surety, shall be disclosed in such reports together with the amount of such losses covered by insurance. If a bond or insurance claim report is filed with any of such bonding companies or insurers, the Master Servicer shall promptly furnish a copy of such report to the Trustee. Any amounts relating to the Mortgage Loans collected by the Master Servicer under any such bond or policy shall be promptly remitted by the Master Servicer to the Securities Administrator for deposit into the Certificate Account. Any amounts relating to the Mortgage Loans collected by any Servicer under any such bond or policy shall be remitted to the Master Servicer to the extent provided in the applicable 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 make available or, upon request, submit to the Trustee, the Securities Administrator, the Rating Agency and the Depositor a copy of its parent company’s annual unaudited financial statements on or prior to May 31 of each year, beginning May 31, 2006. Such financial statements shall include a balance sheet, income statement, statement of retained earnings, statement of additional paid-in capital, statement of changes in financial position and all related notes and schedules and shall be in comparative form, certified by a nationally recognized firm of Independent Accountants to the effect that such statements were examined and prepared in accordance with generally accepted accounting principles applied on a basis consistent with that of the preceding year.

Section 9.04. Power to Act; Procedures.

(a)

The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article X hereof, and each Servicer shall have full power and authority (to the extent provided in the applicable Servicing Agreement) to do any and all things that it may deem necessary or desirable in connection with the servicing and administration of the Mortgage Loans, including but not limited to the power and authority (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, in each case, in accordance with the provisions of this Agreement and the applicable Servicing Agreement, as applicable; provided that the Master Servicer shall not take, or knowingly permit any Servicer to take, any action that is inconsistent with or prejudices the interests of the Trust or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee and the Certificateholders under this Agreement. The Master Servicer shall represent and protect the interests of the Trust in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan and shall not make or knowingly permit any Servicer to make any modification, waiver or amendment of any term of any Mortgage Loan that would cause any REMIC formed hereby to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code. Without limiting the generality of the foregoing, the Master Servicer in its own name or in the name of a Servicer, and each Servicer, to the extent such authority is delegated to such Servicer by the Master Servicer under the applicable Servicing Agreement, is hereby authorized and empowered by the Trust when the Master Servicer or a Servicer, as the case may be, believes it appropriate in its best judgment and in accordance with Accepted Servicing Practices and the applicable Servicing Agreement, to execute and deliver, on behalf of itself and the Certificateholders, the Trustee or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to the Mortgage Loans and with respect to the Mortgaged Properties. The Trustee shall execute, upon request, any limited powers of attorney furnished by the Master Servicer and reasonably acceptable to the Trustee empowering the Master Servicer or any Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request as necessary or appropriate to enable the Master Servicer to master service and administer the Mortgage Loans and carry out its duties hereunder, 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 applicable Servicer). In instituting foreclosures or other similar proceedings, the Master Servicer shall institute such proceedings in its own name (or cause any Servicer instituting such proceedings to do so in its own name) on behalf of the Trust, unless otherwise required by law or otherwise appropriate. If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, then upon request of the Trustee, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 6.09 hereof. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action in the name of the Trustee, be deemed to be the agent of the Trustee.

(b)

In master servicing and administering the Mortgage Loans, the Master Servicer shall employ procedures, and shall cause each Servicer to employ procedures (including, but not limited to, collection procedures), consistent with the applicable Servicing Agreement. Consistent with the foregoing, the Master Servicer may, and may permit any Servicer to, in its discretion (i) waive any late payment charge (but not any prepayment charge or penalty interest in connection with the prepayment of a Mortgage Loan) and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 120 days; provided, however, that the maturity of any Mortgage Loan shall not be extended past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any extension described in clause (ii) above, the Master Servicer shall make or cause such Servicer (if required by the applicable Servicer Agreement) to make Advances on the related Mortgage Loan in accordance with the provisions of Section 5.04 on the basis of the amortization schedule of such Mortgage Loan without modification thereof by reason of such extension. Notwithstanding anything to the contrary in this Agreement, the Master Servicer shall not knowingly permit any modification, waiver or amendment of any material term of any Mortgage Loan (including but not limited to the interest rate, the principal balance, the amortization schedule or any other term affecting the amount or timing of payments on the Mortgage Loan or the collateral therefor), unless: (1) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the applicable Servicer, imminent, (2) such Mortgage Loan provides for any such modification in its Mortgage Note or any addendum thereto, or (3) the Master Servicer shall have provided or (if required by the applicable Servicing Agreement) caused to be provided to the Trustee an Opinion of Counsel (which opinion shall, if provided by the Master Servicer, be an expense reimbursed from the Collection Account pursuant to Section 4.02(v) in writing to the effect that such modification, waiver or amendment would not adversely affect the status of any REMIC formed hereby or the status of any Mortgage Loan as a qualified mortgage under the REMIC Provisions; provided, however that no Opinion of Counsel shall be required in connection with a change in the Mortgage Rate pursuant to the terms of a Convertible Mortgage Loan.

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

(a)

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

(b)

The Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Servicer under the related Servicing Agreement, and shall, in the event that a Servicer fails to perform its obligations in accordance therewith, terminate the rights and obligations of such Servicer thereunder and either act as servicer of the related Mortgage Loans or cause the other parties hereto to enter into a Servicing Agreement (and such parties hereby agree to execute and deliver any such successor Servicing Agreement), with a successor Servicer. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Servicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, and shall be reimbursed therefor initially (i) from a general recovery resulting from such enforcement only to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loans, (ii) from a specific recovery of costs, expenses or attorneys’ fees against the party against whom such enforcement is directed, and then or (iii) to the extent that such amounts are insufficient to reimburse the Master Servicer for the costs of such enforcement from the Collection Account.

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

(a)

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

(b)

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

Section 9.07. Termination of Servicing Agreements; Successor Servicers.

(a)

The Master Servicer shall be entitled to terminate the rights and obligations of any Servicer under the applicable Servicing Agreement in accordance with the terms and conditions of such Servicing Agreement and without any limitation by virtue of this Agreement; provided, however, that in the event of termination of any Servicing Agreement by the Master Servicer, the Master Servicer shall provide for the servicing of the related Mortgage Loans by a successor Servicer to be appointed as provided in the applicable Servicing Agreement.

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

(b)

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

(c)

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

Section 9.08. Master Servicer Liable for Enforcement.

Notwithstanding any Servicing Agreement, the Master Servicer shall remain obligated and liable to the Trustee and the Certificateholders in accordance with the provisions of this Agreement, to the extent of its obligations hereunder, without diminution of such obligation or liability by virtue of such Servicing Agreements. The Master Servicer shall use commercially reasonable efforts to ensure that the Mortgage Loans are serviced in accordance with the provisions of this Agreement and shall enforce the provisions of each Servicing Agreement for the benefit of the Certificateholders. The Master Servicer shall be entitled to enter into any agreement with any Servicer for indemnification of the Master Servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

Section 9.09. No Contractual Relationship Between Servicers, Trustee, the Securities Administrator or Depositor.

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

Section 9.10. Assumption of Servicing Agreement by Trustee.

(a)

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

(b)

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

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

To the extent provided in the applicable Servicing Agreement, to the extent Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer shall cause the related Servicer to enforce such clauses in accordance with the applicable Servicing Agreement. If applicable law prohibits the enforcement of a due-on-sale clause or such clause is otherwise not enforced in accordance with the applicable Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the original Mortgagor may be released from liability in accordance with the applicable Servicing Agreement.

Section 9.12. Release of Mortgage Files.

(a)

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

(b)

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

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

(a)

The Master Servicer shall transmit, or cause the applicable Servicer to transmit, to the Trustee such documents and instruments coming into the possession of the Master Servicer or such Servicer from time to time as are required by the terms hereof or of the applicable Servicing Agreement to be delivered to the Trustee or the Custodian. The Master Servicer shall, and shall (to the extent provided in the applicable Servicing Agreement) cause each Servicer to, provide access to information and documentation regarding the Mortgage Loans to the Trustee, its agents and accountants at any time upon reasonable request and during normal business hours, and to Certificateholders that are savings and loan associations, banks or insurance companies, the Office of Thrift Supervision, the FDIC and the supervisory agents and examiners of such Office and Corporation or examiners of any other federal or state banking or insurance regulatory authority if so required by applicable regulations of the Office of Thrift Supervision or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during normal business hours at the offices of the Master Servicer designated by it. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

(b)

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

(c)

The Master Servicer hereby acknowledges that concurrently with the execution of this Agreement, the Trust 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 Trust shall have a security interest in the Mortgage Loans and in all Mortgage Files representing such Mortgage Loans and in all funds now or hereafter held by, or under the control of, a Servicer or the Master Servicer that are collected by such Servicer or the Master Servicer in connection with the Mortgage Loans, whether as scheduled installments of principal and interest or as full or partial prepayments of principal or interest or as Subsequent Recoveries, Liquidation Proceeds or Insurance Proceeds or otherwise, and in all proceeds of the foregoing and proceeds of proceeds (but excluding any fee or other amounts to which such Servicer is entitled under the applicable Servicing Agreement, or the Master Servicer or the Depositor is entitled to hereunder); and the Master Servicer agrees that so long as the Mortgage Loans are assigned to the Trust and held by the Trustee, all documents or instruments constituting part of the Mortgage Files, and such funds relating to the Mortgage Loans which come into the possession or custody of, or which are subject to the control of, the Master Servicer or any Servicer shall be held by the Master Servicer or such Servicer for and on behalf of the Trustee as the Trustee’s agent and bailee for purposes of perfecting the Trust’s security interest therein as provided by the applicable Uniform Commercial Code or other laws.

(d)

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

The Master Servicer shall use its best reasonable efforts to keep in force and effect, or to cause each Servicer to keep in force and effect (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance), primary mortgage insurance applicable to each Mortgage Loan in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable. The Master Servicer shall not, and shall not knowingly permit any Servicer to, cancel or refuse to renew any such Primary Mortgage Insurance Policy that is in effect at the date of the initial issuance of the Certificates and is required to be kept in force hereunder except as required by a applicable law or in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable.

(b)

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

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

The Master Servicer shall promptly deliver or cause each Servicer to deliver to the Trustee (or its custodian, if any, as directed by the Trustee), upon the execution or receipt thereof the originals of the Primary Mortgage Insurance Policies and any certificates of renewal thereof, and such other documents or instruments that constitute portions of the Mortgage File that come into the possession of the Master Servicer or any Servicer from time to time.

(b)

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

Section 9.26. Annual Independent Accountants’ Servicing Report.

If the Master Servicer (or any of its Affiliates) has, during the course of any fiscal year, directly serviced, as a successor Servicer, any of the Mortgage Loans, then the Master Servicer at its expense shall cause a nationally recognized firm of independent certified public accountants to furnish a statement to the Securities Administrator, the Trustee and the Depositor on or before March 1 of each year, commencing on March 1, 2006, to the effect that, with respect to the most recently ended fiscal year, such firm has examined certain records and documents relating to the Master Servicer’s performance of its servicing obligations under this Agreement and pooling and servicing and trust agreements in material respects similar to this Agreement and to each other and that, on the basis of such examination conducted substantially in compliance with the audit program for mortgages serviced for FHLMC or the Uniform Single Attestation Program for Mortgage Bankers, such firm is of the opinion that the Master Servicer’s activities have been conducted in compliance with this Agreement, or that such examination has disclosed no material items of noncompliance except for (i) such exceptions as such firm believes to be immaterial, (ii) such other exceptions as are set forth in such statement and (iii) such exceptions that the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by FHLMC requires it to report. Copies of such statements shall be provided to any Certificateholder upon request by the Master Servicer, or by the Securities Administrator at the expense of the Master Servicer if the Master Servicer shall fail to provide such copies. If such report discloses exceptions that are material, the Master Servicer shall advise the Trustee and the Securities Administrator whether such exceptions have been or are susceptible of cure, and will take prompt action to do so.

Section 9.27. Merger or Consolidation.

Any Person into which the Master Servicer may be merged or consolidated, or any Person resulting from any merger, conversion, other change in form or consolidation to which the Master Servicer shall be a party, or any Person succeeding to the business of the Master Servicer, shall be the successor to the Master Servicer hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or resulting Person to the Master Servicer shall be a Person that shall be qualified and approved to service mortgage loans for FNMA or FHLMC and shall have a net worth of not less than $15,000,000.

Section 9.28. Resignation of Master Servicer; Compensation of Successor Master Servicer.

Except as otherwise provided in Sections 9.27 and 9.29 hereof, the Master Servicer shall not resign from the obligations and duties hereby imposed on it unless it or the Trustee 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. No such resignation shall become effective until the Trustee shall have assumed, or a successor master servicer shall have been appointed by the Trustee and until such successor shall have assumed, the Master Servicer’s responsibilities and obligations under this Agreement. Notice of such resignation shall be given promptly by the Master Servicer to the Depositor. If ▇▇▇▇▇ Fargo Bank, N.A. resigns or is removed as Master Servicer, it shall resign (or in the case of removal, be deemed removed) as Securities Administrator.

In connection with the appointment of any successor master servicer or the assumption of the duties of the Master Servicer, the Trustee may make such arrangements for the compensation of such successor master servicer out of payments on the Mortgage Loans as the Trustee and such successor master servicer shall agree. If the successor master servicer does not agree that the proposed compensation is fair, such successor master servicer shall obtain two quotations of market compensation from third parties actively engaged in the servicing of single-family mortgage loans; provided, however, that ▇▇▇▇▇▇▇▇▇, as a Servicer of a substantial portion of the Mortgage Loans, shall have the right, but not the obligation, to be appointed successor master servicer in the event that the Trustee, in its sole discretion, decides not to assume the duties of the Master Servicer itself; and provided, further, that the Rating Agency shall confirm in writing that any appointment of a successor Master Servicer (other than the Trustee) will not result in a downgrade in the then current rating of any Class of Certificates.

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

Except as expressly provided herein, the Master Servicer shall not assign or transfer any of its rights, benefits or privileges hereunder to any other Person, or delegate to or subcontract with, or authorize or appoint any other Person to perform any of the duties, covenants or obligations to be performed by the Master Servicer hereunder; provided, however, that the Master Servicer shall have the right without the prior written consent of the Trustee, the Depositor or the Rating Agency to delegate or assign to or subcontract with or authorize or appoint an Affiliate of the Master Servicer to perform and carry out any duties, covenants or obligations to be performed and carried out by the Master Servicer hereunder. In no case, however, shall any such delegation, subcontracting or assignment to an Affiliate of the Master Servicer relieve the Master Servicer of any liability hereunder. Written notice of such permitted assignment shall be given promptly by the Master Servicer to the Depositor and the Trustee. If, pursuant to any provision hereof, the duties of the Master Servicer are transferred to a successor master servicer, the entire amount of the Master Servicing Fees and other compensation payable to the Master Servicer pursuant hereto, including amounts payable to or permitted to be retained or withdrawn by the Master Servicer pursuant to Section 9.21 hereof, shall thereafter be payable to such successor master servicer.

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

Neither the Master Servicer nor any of the directors, officers, employees or agents of the Master Servicer shall be under any liability to the Trust, 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 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 the Master Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Master Servicer shall be under no obligation to appear in, prosecute or defend any legal action that is not incidental to its duties to master service the Mortgage Loans in accordance with this Agreement and that in its opinion may involve it in any expenses or liability; provided, however, that the Master Servicer may in its sole discretion undertake any such action that it may deem necessary or desirable in respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust and the Master Servicer shall be entitled to be reimbursed therefor out of the Collection Account it maintains as provided by Section 4.02.

The Master Servicer shall not be liable for any acts or omissions of any Servicer. In particular, the Master Servicer shall not be liable for any course of action taken by the Servicers with respect to loss mitigation of defaulted Mortgage Loans at the direction of the Seller.

Section 9.31. Indemnification; Third-Party Claims.

(a)

Subject to Section 9.30, the Master Servicer agrees to indemnify the Indemnified Persons for, and to hold them harmless against, any loss, liability or expense (except as otherwise provided herein with respect to expenses) (including reasonable legal fees and disbursements of counsel) incurred on their part that may be sustained in connection with, arising out of, or relating to this Agreement or the Certificates (i) related to the Master Servicer’s failure to perform its duties in compliance with this Agreement (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement or, with respect to any Indemnified Person, results from a failure to perform by such Indemnified Person) or (ii) incurred by reason of the Master Servicer’s willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder, provided, in each case, that with respect to any such claim or legal action (or pending or threatened claim or legal action), the Trustee shall have given the Master Servicer and the Seller written notice thereof promptly after the Trustee shall have with respect to such claim or legal action knowledge thereof. The Trustee’s failure to give such notice shall not affect the Indemnified Person’s right to indemnification hereunder. This indemnity shall survive the resignation or removal of the Trustee, Master Servicer or the Securities Administrator and the termination of this Agreement.

(b)

The Trust will indemnify any Indemnified Person for any loss, liability or expense of any Indemnified Person not otherwise indemnified by the Master Servicer that is referred to in Subsection (a) above.

(c)

The Securities Administrator agrees to indemnify the Indemnified Persons (other than the Securities Administrator) for, and to hold them harmless against, any loss, liability or expense (except as otherwise provided herein with respect to expenses) (including reasonable legal fees and disbursements of counsel) incurred on their part (i) in connection with, arising out of, or relating to the Securities Administrator’s failure to file a Form 10-K in accordance with Section 9.23 (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement or, with respect to any Indemnified Person, results from a failure to perform by such Indemnified Person), (ii) by reason of the Securities Administrator’s willful misfeasance, bad faith or gross negligence in the performance of such obligations hereunder including pursuant to Section 9.23 or (iii) by reason of the Securities Administrator’s reckless disregard of its obligations pursuant to Section 9.23, provided, in each case, that with respect to any such claim or legal action (or pending or threatened claim or legal action), the Trustee shall have given the Securities Administrator written notice thereof promptly after the Trustee shall have with respect to such claim or legal action knowledge thereof. The Trustee’s failure to give such notice shall not affect the Indemnified Person’s right to indemnification hereunder. This indemnity shall survive the resignation or removal of the Trustee, Master Servicer or the Securities Administrator and the termination of this Agreement.

Section 9.32. Realization upon Troubled Mortgage Loans.

The Master Servicer shall have the right to cause a Servicer to sell or work out any Mortgage Loan as to which the Master Servicer reasonably believes that default in payment is likely, provided, however, that, with respect to any such sale of a Mortgage Loan by a Servicer, the related sale price shall be no less than the Scheduled Principal Balance of such Mortgage Loan as of the last day of the Due Period immediately preceding the date of such sale plus accrued interest thereon through such sale date. Any and all proceeds from such a sale shall be deemed to be Liquidation Proceeds hereunder and any such Mortgage Loan which has been sold shall be deemed a Liquidated Mortgage Loan hereunder.

ARTICLE X

REMIC ADMINISTRATION

Section 10.01. REMIC Administration.

(a)

As set forth in the Preliminary Statement hereto, the Trust shall elect REMIC status in accordance with the REMIC Provisions with respect to each of the three REMICs described in the Preliminary Statement. The Trust shall make such elections on Forms 1066 or other appropriate federal tax or information return (prepared and filed by the Securities Administrator) for the taxable year ending on the last day of the calendar year in which the Certificates are issued. The regular interests in each REMIC created hereunder and the related residual interests shall be as designated in the Preliminary Statement.

(b)

The Closing Date is hereby designated as the “Startup Day” of each REMIC within the meaning of section 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. The Trustee, on behalf of the Trust, shall sign and the Securities Administrator shall prepare and file with the Internal Revenue Service (“IRS”), on behalf of each REMIC, an application on IRS Form SS-4. The Securities Administrator, upon receipt from the IRS of the Notice of Taxpayer Identification Number Assigned for each REMIC, shall promptly forward copies of such notice to the Trustee, the Master Servicer and the Depositor. The Securities Administrator will file an IRS Form 8811.

(c)

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.

(d)

The Trustee shall sign and the Securities Administrator (at its expense) shall prepare and file (or cause to be prepared and filed) on behalf of the Trust Fund, based upon information calculated in accordance with this Agreement pursuant to instructions given by the Depositor, federal tax returns and appropriate state income tax returns and such other returns as may be required by applicable law relating to the Trust Fund, and the Securities Administrator shall file any other documents to the extent required by applicable state tax law (to the extent such documents are in the possession of the Securities Administrator or the Trustee). The Securities Administrator shall forward copies to the Depositor of all such returns and such other information within the control of the Securities Administrator as the Depositor may reasonably request in writing. The Securities Administrator shall prepare and disseminate to Certificateholders Form 1099 (supplemental tax information) to the extent required by applicable law. The Master Servicer will indemnify the Securities Administrator and the Trustee for any liability of or assessment against the Securities Administrator or the Trustee resulting from any error in any of such tax or information returns directly resulting from errors in the information provided by such Master Servicer (other than information that is derived solely from information provided by any Servicer).

If any Disqualified Organization acquires any ownership interest in a Residual Certificate, then the Securities Administrator will upon request provide to the Internal Revenue Service, and to the persons specified in Sections 860E(e)(3) and (6) of the Code, such information as required in Section 860D(a)(6)(B) of the Code needed to compute the tax imposed under Section 860E(e) of the Code on transfers of residual interests to disqualified organizations. The Securities Administrator and the Trustee shall be entitled to additional compensation from such person for the cost of providing such information.

(e)

The Securities Administrator or its designee shall perform on behalf of each REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions, or other compliance guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, if required by the Code, the REMIC Provisions, or other such guidance, the Securities Administrator shall provide (i) to the Treasury or other governmental authority such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any disqualified person or organization and (ii) to the Certificateholders such information or reports as are required by the Code or REMIC Provisions. The Securities Administrator, however, shall have no information or other tax reporting obligations with respect to the Final Maturity Reserve Trust.

(f)

The Depositor, the Securities Administrator, the Trustee, the Master Servicer and the Holders of Certificates shall take any action or cause each REMIC to take any action reasonably necessary to maintain the status of such REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to or maintain such status. None of 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 (i) endanger the status of such REMIC as a REMIC or (ii) result in the imposition of a tax upon any REMIC (including but not limited to the tax on prohibited transactions as defined in Code Section 860F(a)(2) and the tax on prohibited contributions set forth on Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee, the Securities Administrator and the Master Servicer have received an Opinion of Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not endanger such status or result in the imposition of such a tax. In addition, prior to taking any action with respect to any REMIC or the assets therein, or causing such 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 and the Master Servicer, or their respective designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall take any such action or cause such 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 Trust 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 such REMIC or, if no such amounts are available, out of other amounts held in the Collection Account, and shall reduce amounts otherwise payable to holders of regular interests in such REMIC, as the case may be.

(h)

The Securities Administrator, on behalf of the Trust, shall, for federal income tax purposes, maintain books and records with respect to each REMIC on a calendar year and on an accrual basis.

(i)

No additional contributions of assets shall be made to any REMIC, except as expressly provided in this Agreement with respect to Qualified Substitute Mortgage Loans.

(j)

None of the Trustee, the Securities Administrator or the Master Servicer shall enter into any arrangement by which any REMIC will receive a fee or other compensation for services.

(k)

Upon the written request of a Rating Agency, the Securities Administrator shall deliver to such Rating Agency an Officer’s Certificate stating such party’s compliance with the provisions of this Section 10.01.

(l)

The Securities Administrator shall treat each of the Available Funds Cap Reserve Fund and the Final Maturity Reserve Trust as an outside reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h) owned by the holders of the Class A-X Certificates and the Class I Certificates, respectively, and not assets of any REMIC. The Securities Administrator shall treat the rights of the Class A Certificateholders to receive distributions from the Available Funds Cap Reserve Fund to cover Available Funds Cap Shortfalls as payments under a cap contract written by the Class A-X Certificateholders in favor of the Class A Certificateholders. Thus, the Class A Certificates shall be treated as representing not only ownership of regular interests in a REMIC, but also ownership of an interest in an interest rate cap contract. The Class I Certificateholder shall be treated as the owner of the Final Maturity Reserve Trust and any payments made from the Final Maturity Reserve Trust to beneficial owners of Certificates (other than the Class I Certificates) shall be treated for federal income tax purposes as payments made by the Class I Certificateholder in exchange for an interest in the Certificates then owned by such beneficial owners.

Section 10.02. Prohibited Transactions and Activities.

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

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

In the event that a REMIC fails to qualify as a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a result of a prohibited transaction or prohibited contribution under the REMIC Provisions due to the negligent performance by the Securities Administrator or the Trustee of its duties and obligations set forth herein, the Securities Administrator and the Trustee, as applicable, shall indemnify the Holder of the Residual Certificate against any and all losses, claims, damages, liabilities or expenses (“Losses”) resulting from its own such negligence; provided, that neither the Trustee nor the Securities Administrator shall be liable for any such Losses attributable to the action or inaction of the other party or of the Master Servicer, the Depositor, or the Holder of such Residual Certificate, as applicable, or for any such Losses resulting from misinformation provided by the Holder of such Residual Certificate on which the Trustee or the Securities Administrator, as applicable, 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 either the Trustee or the Securities Administrator have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement, (2) for any Losses other than arising out of a negligent performance by the Trustee 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).

Section 10.04. REO Property.

(a)

Notwithstanding any other provision of this Agreement, the Master Servicer, acting on behalf of the Trust and the Trustee, shall not (except to the extent provided in the applicable Servicing Agreement), permit any Servicer to, rent, lease, or otherwise earn income on behalf of any REMIC with respect to any REO Property which might cause such REO Property to fail to qualify as “foreclosure” property within the meaning of section 860G(a)(8) of the Code or result in the receipt by any REMIC of any “income from non-permitted assets” within the meaning of section 860F(a)(2) of the Code or any “net income from foreclosure property” which is subject to tax under the REMIC Provisions unless the Master Servicer has advised, or has caused the applicable Servicer to advise, the Trustee in writing to the effect that, under the REMIC Provisions, such action would not adversely affect the status of any REMIC as a REMIC and any income generated for any REMIC by the REO Property would not result in the imposition of a tax upon such REMIC.

(b)

The Master Servicer shall make, or shall cause the applicable Servicer (to the extent provided in its Servicing Agreement) to make, reasonable efforts to sell any REO Property for its fair market value. In any event, however, the Master Servicer shall, or shall cause the applicable Servicer (to the extent provided in its Servicing Agreement) to, dispose of any REO Property within three years from the end of the calendar year of its acquisition by the Trust unless the Securities Administrator or the Trustee has received a grant of extension from the Internal Revenue Service. If the Securities Administrator or the Trustee has received such an extension, then (a) such party shall provide a copy of such extension to the other party and to the Master Servicer and (b) the Master Servicer, acting on behalf of the Trust hereunder, shall, or shall cause the applicable Servicer to, continue to attempt to sell the REO Property for its fair market value for such period longer than three years as such extension permits (the “Extended Period”). If the Trust has not received such an extension and the Master Servicer acting on behalf of the Trust hereunder, or the applicable Servicer is unable to sell the REO Property within 33 months after its acquisition by the Trust Fund or if the Trust has received such an extension, and the Master Servicer acting on behalf of the Trust hereunder, is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Master Servicer shall, or shall cause the applicable Servicer to, before the end of the three year period or the Extended Period, as applicable, (i) purchase such REO Property at a price equal to the REO Property’s fair market value or (ii) auction the REO Property to the highest bidder (which may be the Master Servicer) in an auction reasonably designed to produce a fair price prior to the expiration of the three-year period or the Extended Period, as the case may be.

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

Section 11.03. Amendment.

(a)

This Agreement may be amended from time to time by the Depositor, the Seller, the Master Servicer, the Securities Administrator, the Trustee and the Delaware Trustee, without notice to or the consent of any of the Holders, (i) to cure any ambiguity, (ii) to cause the provisions herein to conform to or be consistent with or in furtherance of the statements made with respect to the Certificates, the Trust, the Trust Fund or this Agreement in any Offering Document; or to correct or supplement any provision herein which may be inconsistent with any other provisions herein, (iii) to make any other provisions with respect to matters or questions arising under this Agreement or (iv) to add, delete, or amend any provisions to the extent necessary or desirable to comply with any requirements imposed by the Code and the REMIC Provisions. No such amendment effected pursuant to the preceding sentence shall, as evidenced by an Opinion of Counsel, adversely affect the status of any REMIC created pursuant to this Agreement, nor shall such amendment effected pursuant to clause (iii) of such sentence adversely affect in any material respect the interests of any Holder. Prior to entering into any amendment without the consent of Holders pursuant to this paragraph, the Trustee shall receive an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that such amendment is permitted under this paragraph. Any such amendment shall be deemed not to adversely affect in any material respect any Holder, if the Trustee receives written confirmation from the Rating Agency that such amendment will not cause the Rating Agency to reduce, qualify or withdraw the then current rating assigned to the Certificates (and any Opinion of Counsel received by the Trustee in connection with any such amendment may rely expressly on such confirmation as the basis therefor).

(b)

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

(c)

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

(d)

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

(e)

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

In addition, the Transferor has conducted a reasonable investigation at the time of the transfer and found that the Transferee had historically paid its debts as they came due and found no significant evidence to indicate that the Transferee will not continue to pay its debts as they become due.
