This Pooling and Servicing Agreement is dated as of March 1, 2006 (the “Agreement”), among CREDIT SUISSE FIRST BOSTON MORTGAGE SECURITIES CORP., a Delaware corporation, as depositor (the “Depositor”), XXXXXXXXX MORTGAGE HOME LOANS, INC., a Delaware corporation, as seller (the “Seller”), XXXXX FARGO BANK, N.A., a national banking association, as master servicer (in such capacity, the “Master Servicer”) and as securities administrator (in such capacity, the “Securities Administrator”), WILMINGTON TRUST COMPANY, a Delaware banking corporation, as Delaware trustee (the “Delaware Trustee”) and LASALLE BANK NATIONAL ASSOCIATION, a national banking association, as trustee (in such capacity, the “Trustee”) and custodian (in such capacity, the “Custodian”).

PRELIMINARY STATEMENT:

On March 21, 2006 the Depositor formed Xxxxxxxxx Mortgage Securities Trust 2006-2, as a Delaware statutory trust (the “Trust”) pursuant to (i) the Trust Agreement, dated as of March 21, 2006 (the “Original Trust Agreement”), among the Depositor, the Trustee and the Delaware Trustee and (ii) a Certificate of Trust filed with the Secretary of State of the State of Delaware on March 21, 2006.

The parties to this Agreement desire to amend and restate the Original Trust Agreement in its entirety, and, as evidenced by their signatures hereto, the Original Trust Agreement is hereby amended, restated and replaced in its entirety as of the date first written above by this Agreement.

Through this Agreement, the Depositor intends to cause the issuance and sale of the Trust’s Mortgage Pass-Through Certificates, Series 2006-2 (the “Certificates”) representing in the aggregate the entire beneficial ownership of the Trust, the primary assets of which are the Mortgage Loans (as defined below).

On or prior to the Closing Date, the Depositor acquired the Mortgage Loans from the Seller. On the Closing Date, the Depositor will sell the Mortgage Loans and certain other property to the Trust and receive in consideration therefor Certificates evidencing the entire beneficial ownership of the Trust.

The Depositor intends to sell the Certificates, to be issued hereunder in multiple classes, which in the aggregate will evidence the entire beneficial ownership interest in the Trust. The Certificates will consist of sixteen classes of certificates, designated as (i) the Class A-1-A Certificates, (ii) the Class A-1-B Certificates, (iii) the Class A-1-C Certificates, (iv) the Class A-2-A Certificates, (v) the Class A-2-B Certificates, (vi) the Class A-2-C Certificates, (vii) the Class A-X-1 Certificates, (viii) the Class A-X-2 Certificates, (ix) the Class A-R Certificates, (x) the Class B-1 Certificates, (xi) the Class B-2 Certificates, (xii) the Class B-3 Certificates, (xiii) the Class B-4 Certificates, (xiv) the Class B-5 Certificates, (xv) the Class B-6 and (xvi) the Class I Certificates.

For federal income tax purposes, the Trust Fund (exclusive of the Additional Collateral, the Yield Maintenance Agreements, the Auction Swap Agreement, the Yield Maintenance Account, the Final Maturity Reserve Trust and the Final Maturity Reserve Account, collectively, the “Excluded Trust Assets”) is comprised of three REMICs in a tiered REMIC structure – REMIC 1 , REMIC 2 , and the upper tier REMIC. Each Certificate, other than the Class A-R Certificate, shall represent ownership of a regular interest in the Upper-Tier REMIC, as described herein. In addition, the Class A-1-A, Class A-1-B, Class A-1-C, Class A-2-A, Class A-2-B, Class A-2-C, Class A-X-1 and Class A-X-2 Certificates represent the right to receive payments from the Yield Maintenance Account as provided in Section 5.09. Each Class of Certificates (other than the Class A-X-1 and Class A-X-2 Certificates) also represents the right to receive payments in respect of the Final Maturity Reserve Account. The owners of the Class I Certificates beneficially own the Final Maturity Reserve Account and the Final Maturity Reserve Trust. The Class A-R Certificate represents ownership of the sole class of residual interest in each REMIC.

REMIC 1 will hold as its assets all of the assets constituting the Trust Fund (exclusive of the Excluded Trust Assets) and will issue interests (the “Lower Tier Regular Interests,” which will be uncertificated and will represent the regular interests in REMIC 1) and a residual interest (the “LT1-R Interest”), which will represent the sole class of residual interest in REMIC 1. REMIC 2 will hold as its assets the Lower Tier Regular Interests in REMIC 1 and will issue interests (also, the “Lower Tier Regular Interests, which will be uncertificated and will represent the regular interests in REMIC 2) and a residual interest (the “LT2-R Interest”), which will represent the sole class of residual interest in REMIC 2. The Trustee will hold the Lower Tier Regular Interests in REMIC 2 as assets of the Upper Tier REMIC. The Certificates, other than the Class A-R Certificate, will represent regular interests in the Upper Tier REMIC, and the Class A-R Certificate will represent the sole class of residual interest in the Upper Tier REMIC as well as ownership of the LT1-R and LT2-R Interests.

For purposes of the REMIC Provisions, the startup day is the Closing Date. All REMIC regular and residual interests created hereby will be retired on or before the Latest Possible Maturity Date.

If the Seller does not cure such defect or deliver such missing document within such time period, the Seller shall either repurchase or substitute for such Mortgage Loan in accordance with Section 2.03 hereof.

The Depositor herewith delivers to the Trustee an executed copy of the Mortgage Loan Purchase Agreement.

SECTION 2.02. Acceptance by Trustee.

The Trustee hereby accepts its appointment as Custodian hereunder and acknowledges the receipt, subject to the provisions of Section 2.01 and subject to the review described below and any exceptions noted on the exception report described in the next paragraph below, of the documents referred to in Section 2.01 above and all other assets included in the definition of “Trust Fund” and declares that, in its capacity as Custodian, it holds and will hold such documents and the other documents delivered to it constituting a Mortgage File, and that it holds or will hold all such assets and such other assets included in the definition of “Trust Fund” in trust for the exclusive use and benefit of all present and future Certificateholders.

The Trustee further agrees, for the benefit of the Certificateholders, to review each Mortgage File delivered to it and to certify and deliver to the Depositor, the Seller and each Rating Agency an interim certification in substantially the form attached hereto as Exhibit G-2, within 90 days after the Closing Date (or, with respect to any document delivered after the Startup Day, within 45 days of receipt and with respect to any Qualified Substitute Mortgage, within five Business Days after the assignment thereof) that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan specifically identified in the exception report annexed thereto as not being covered by such certification), (i) all documents required to be delivered to it pursuant Section 2.01 of this Agreement are in its possession, (ii) such documents have been reviewed by it and have not been mutilated, damaged or torn and relate to such Mortgage Loan and (iii) based on its examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule that corresponds to items (i), (ii), (iii), (xiii), (xiv) and (xviii) of the Mortgage Loan Schedule (to the extent such items are required to be delivered to it as part of the Mortgage Files pursuant to Section 2.01) accurately reflects information set forth in the Mortgage File. It is herein acknowledged that, in conducting such review, the Trustee is under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine that they are genuine, enforceable, or appropriate for the represented purpose or that they have actually been recorded or that they are other than what they purport to be on their face.

No later than 180 days after the Closing Date, the Trustee shall deliver to the Depositor and the Seller a final certification in the form annexed hereto as Exhibit G-3 evidencing the completeness of the Mortgage Files, with any applicable exceptions noted thereon.

If, in the process of reviewing the Mortgage Files and making or preparing, as the case may be, the certifications referred to above, the Trustee finds any document or documents constituting a part of a Mortgage File to be missing or not conforming to the requirements set forth herein, at the conclusion of its review the Trustee (or the Custodian as its designated agent) shall promptly notify the Seller, the Depositor and the Master Servicer. In addition, upon the discovery by the Seller or the Depositor (or upon receipt by the Trustee of written notification of such breach) of a breach of any of the representations and warranties made by the Seller in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan that materially adversely affects such Mortgage Loan or the interests of the related Certificateholders in such Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties to this Agreement.

The Depositor and the Trustee intend that the assignment and transfer herein contemplated constitute a sale of the Mortgage Loans, the related Mortgage Notes and the related documents, conveying good title thereto free and clear of any liens and encumbrances, from the Depositor to the Trustee and that such property not be part of the Depositor’s estate or property of the Depositor in the event of any insolvency by the Depositor. In the event that such conveyance is deemed to be, or to be made as security for, a loan, the parties intend that the Depositor shall be deemed to have granted and does hereby grant to the Trustee a first priority perfected security interest in all of the Depositor’s right, title and interest in and to the Mortgage Loans, the related Mortgage Notes and the related documents, and that this Agreement shall constitute a security agreement under applicable law.

SECTION 2.03. Repurchase or Substitution of Mortgage Loans by the Seller.

(a)

Upon discovery or receipt of written notice that a document does not comply with the requirements of Section 2.01 hereof, or that a document is missing from, a Mortgage File or of the breach by the Seller of any representation, warranty or covenant under the Mortgage Loan Purchase Agreement or in Section 2.04 or Section 2.08 hereof in respect of any Mortgage Loan which materially adversely affects the value of that Mortgage Loan or the interest therein of the Certificateholders, the Trustee (or the Custodian as its designated agent) shall promptly notify the Seller of such noncompliance, missing document or breach and request that the Seller deliver such missing document or cure such noncompliance or breach within 90 days from the date that the Seller was notified of such missing document, noncompliance or breach, and if the Seller does not deliver such missing document or cure such noncompliance or breach in all material respects during such period, the Trustee shall enforce the Seller’s obligation under the Mortgage Loan Purchase Agreement and cause the Seller to repurchase that Mortgage Loan from the Trust Fund at the Purchase Price on or prior to the Determination Date following the expiration of such 90 day period (subject to Section 2.03(e) below); provided, however, that, in connection with any such breach that could not reasonably have been cured within such 90 day period, if the Seller shall have commenced to cure such breach within such 90 day period, the Seller shall be permitted to proceed thereafter diligently and expeditiously to cure the same within the additional period provided under the Mortgage Loan Purchase Agreement; and, provided further, that, in the case of the breach of any representation, warranty or covenant made by the Seller in Schedule III to the Mortgage Loan Purchase Agreement, the Seller shall be obligated to cure such breach or purchase the affected Mortgage Loans for the Purchase Price or, if the Mortgage Loan or the related Mortgaged Property acquired with respect thereto has been sold, then the Seller shall pay, in lieu of the Purchase Price, any excess of the Purchase Price over the Net Liquidation Proceeds received upon such sale. The Purchase Price for the repurchased Mortgage Loan or such other amount due shall be deposited in the Distribution Account on or prior to the next Determination Date after the Seller’s obligation to repurchase such Mortgage Loan arises. The Trustee, upon receipt of written certification from the Securities Administrator of the related deposit in the Distribution Account, shall release to the Seller the related Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Seller shall furnish to it and as shall be necessary to vest in the Seller any Mortgage Loan released pursuant hereto and the Trustee shall have no further responsibility with regard to such Mortgage File (it being understood that the Trustee shall have no responsibility for determining the sufficiency of such assignment for its intended purpose). In lieu of repurchasing any such Mortgage Loan as provided above, the Seller may cause such Mortgage Loan to be removed from the Trust Fund (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(d) below. It is understood and agreed that the obligation of the Seller to cure or to repurchase (or to substitute for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy against the Seller respecting such omission, defect or breach available to the Trustee on behalf of the Certificateholders.

The Trustee shall enforce the obligations of the Seller under the Mortgage Loan Purchase Agreement including, without limitation, any obligation of the Seller to purchase a Mortgage Loan on account of missing or defective documentation or on account of a breach of a representation, warranty or covenant as described in this Section 2.03(a).

Any costs and expenses incurred by the Trustee enforcing the obligations of the Seller under this Section 2.03(a) shall be reimbursable to the Trustee from amounts on deposit in the Distribution Account.

(b)

If pursuant to the provisions of Section 2.03(a), the Seller repurchases or otherwise removes from the Trust Fund a Mortgage Loan that is a MERS Mortgage Loan, the Seller will take (or shall cause the applicable Servicer to take), at the expense of the Seller (with the cooperation of the Depositor, the Trustee and the Master Servicer), such actions as are necessary either to (i) cause MERS to execute and deliver an Assignment of Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and regulations or (ii) cause MERS to designate on the MERS® System the Seller or its designee as the beneficial holder of such Mortgage Loan.

(c)

[Reserved].

(d)

Any substitution of Qualified Substitute Mortgage Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a) above must be effected prior to the last Business Day that is within two years after the Closing Date. As to any Deleted Mortgage Loan for which the Seller substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution shall be effected by the Seller delivering to the Trustee, for such Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2.01 hereof (subject to the exceptions provided therein), together with an Officers’ Certificate stating that each such Qualified Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Adjustment (as described below), if any, in connection with such substitution; provided, however, that, in the case of any Qualified Substitute Mortgage Loan that is a MERS Mortgage Loan, the Seller shall provide such documents and take such other action with respect to such Qualified Substitute Mortgage Loans as are required pursuant to Section 2.01 hereof. The Trustee shall acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans and, within five Business Days thereafter, shall review such documents as specified in Section 2.02 hereof and deliver to the related Servicer, with respect to such Qualified Substitute Mortgage Loan or Loans, a certification substantially in the form attached hereto as Exhibit G-2, with any exceptions noted thereon. Within 180 days of the date of substitution, the Trustee shall deliver to the Seller and the Master Servicer a certification substantially in the form of Exhibit G-3 hereto with respect to such Qualified Substitute Mortgage Loan or Loans, with any exceptions noted thereon. Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution are not part of the Trust Fund and will be retained by the Seller. For the month of substitution, distributions to Certificateholders will reflect the collections and recoveries in respect of such Deleted Mortgage Loan in the Due Period preceding the month of substitution and the Depositor or the Seller, as the case may be, shall thereafter be entitled to retain all amounts subsequently received in respect of such Deleted Mortgage Loan. The Seller shall give or cause to be given written notice to the Certificateholders that such substitution has taken place, shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan Schedule to the Trustee. Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall constitute part of the Trust Fund and shall be subject in all respects to the terms of this Agreement and, in the case of a substitution effected by the Seller, the Mortgage Loan Purchase Agreement, including, in the case of a substitution effected by the Seller all representations and warranties thereof included in the Mortgage Loan Purchase Agreement and all representations and warranties thereof set forth in Section 2.04 hereof, in each case as of the date of substitution.

For any month in which the Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Seller shall determine, and provide written certification to the Trustee and the Seller as to, the amount (each, a “Substitution Adjustment”), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate, as to each such Qualified Substitute Mortgage Loan, of the principal balance thereof as of the date of substitution, together with one month’s interest on such principal balance at the applicable Net Loan Rate. On or prior to the next Determination Date after the Seller’s obligation to repurchase the related Deleted Mortgage Loan arises, the Seller will deliver or cause to be delivered to the Securities Administrator for deposit in the Distribution Account an amount equal to the related Substitution Adjustment, if any, and the Trustee, upon receipt of the related Qualified Substitute Mortgage Loan or Loans and an acknowledgment from the Securities Administrator of its receipt of the deposit to the Distribution Account, shall release to the Seller the related Mortgage File or Files and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Seller shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto.

In addition, the Seller shall obtain at its own expense and deliver to the Trustee an Opinion of Counsel to the effect that such substitution (either specifically or as a class of transactions) will not cause (a) any federal tax to be imposed on the Trust Fund, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(a)(l) of the Code or on “contributions after the startup date” under Section 860G(d)(l) of the Code, or (b) any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding. If such Opinion of Counsel cannot be delivered, then such substitution may only be effected at such time as the required Opinion of Counsel can be given.

(e)

Upon discovery by the Seller, the Master Servicer, a Servicer or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall within two Business Days give written notice thereof to the other parties. In connection therewith, the Seller shall repurchase or, subject to the limitations set forth in Section 2.03(d), substitute one or more Qualified Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.03(a) above, if made by the Seller. The Trustee shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty.

SECTION 2.04. Representations and Warranties of the Seller with Respect to the Mortgage Loans.

The Seller hereby represents and warrants to the Trustee for the benefit of the Certificateholders that the representations and warranties made by the Seller pursuant to Schedule III to the Mortgage Loan Purchase Agreement are hereby being made to the Trustee and are true and correct as of the Closing Date.

With respect to the representations and warranties incorporated in this Section 2.04 that are made to the best of the Seller’s knowledge or as to which the Seller has no knowledge, if it is discovered by the Depositor, the Seller, the Master Servicer or the Trustee that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interest therein of the Certificateholders then, notwithstanding the Seller’s lack of knowledge with respect to the substance of such representation and warranty being inaccurate at the time the representation or warranty was made, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

Within 90 days of its discovery or its receipt of notice of any such missing or materially defective documentation or any such breach of a representation or warranty, the Seller shall promptly deliver such missing document or cure such defect or breach in all material respects or, in the event such defect or breach cannot be cured, the Seller shall repurchase the affected Mortgage Loan or cause the removal of such Mortgage Loan from the Trust Fund and substitute for it one or more Qualified Substitute Mortgage Loans, in either case, in accordance with Section 2.03 hereof.

It is understood and agreed that the representations and warranties incorporated in this Section 2.04 shall survive delivery of the Mortgage Files to the Trustee and shall inure to the benefit of the Certificateholders notwithstanding any restrictive or qualified endorsement or assignment. Upon discovery by any of the Depositor, the Seller, the Master Servicer or the Trustee of a breach of any of the foregoing representations and warranties which materially and adversely affects the value of any Mortgage Loan or the interests therein of the Certificateholders, the party discovering such breach shall give prompt written notice to the other parties, and in no event later than two Business Days from the date of such discovery. It is understood and agreed that the obligations of the Seller set forth in Section 2.03(a) hereof to cure, substitute for or repurchase a related Mortgage Loan pursuant to the Mortgage Loan Purchase Agreement constitute the sole remedies available to the Certificateholders or to the Trustee on their behalf respecting a breach of the representations and warranties incorporated in this Section 2.04.

ARTICLE III

ADMINISTRATION AND SERVICING
OF THE MORTGAGE LOANS

SECTION 3.01. Master Servicer to Service and Administer the Mortgage Loans.

The Master Servicer shall supervise, monitor and oversee the obligation of the Servicers to service and administer their respective Mortgage Loans in accordance with the terms of the applicable Servicing Agreement and, where applicable, the Correspondent Sellers Guide and the Master Servicing Guide, and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices and, where applicable, the Master Servicing Guide. Furthermore, the Master Servicer shall oversee and consult with each Servicer as necessary from time-to-time to carry out the Master Servicer’s obligations hereunder, shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by each Servicer and shall cause each Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by such Servicer under the applicable Servicing Agreement. The Master Servicer shall independently and separately monitor each Servicer’s servicing activities with respect to each related Mortgage Loan, reconcile the results of such monitoring with such information provided in the previous sentence on a monthly basis and coordinate corrective adjustments to the Servicers’ and Master Servicer’s records, and based on such reconciled and corrected information, prepare the statements specified in Section 5.04 and any other information and statements required hereunder. The Master Servicer shall reconcile the results of its Mortgage Loan monitoring with the actual remittances of the Servicers to the related Servicing Accounts pursuant to the applicable Servicing Agreements.

The Trustee shall furnish the Servicers and the Master Servicer with any limited powers of attorney and other documents in form acceptable to the Trustee, necessary or appropriate to enable the Servicers and the Master Servicer to service and administer the related Mortgage Loans and REO Property, which limited powers of attorney shall provide that the Trustee will not be liable for the actions or omissions of the Servicers or Master Servicer in exercising such powers.

The Master Servicer shall not without the Trustee’s written consent (i) initiate any action, suit or proceeding solely under the Trustee’s name without indicating the Master Servicer’s representative capacity or (ii) take any action with the intent to cause, and which actually does cause, the Trustee to be registered to do business in any state. The Master Servicer shall indemnify the Trustee for any and all costs, liabilities and expenses incurred by the Trustee in connection with the negligent or willful misuse of such powers of attorney by the Master Servicer.

The Trustee shall provide access to the records and documentation in possession of the Trustee (including in its capacity as Custodian hereunder) regarding the related Mortgage Loans and REO Property and the servicing thereof to the Certificateholders, the FDIC, and the supervisory agents and examiners of the FDIC, such access being afforded only upon reasonable prior written request and during normal business hours at the office of the Trustee; provided, however, that, unless otherwise required by law, the Trustee shall not be required to provide access to such records and documentation if the provision thereof would violate the legal right to privacy of any Mortgagor. The Trustee shall allow representatives of the above entities to photocopy any of the records and documentation and shall provide equipment for that purpose at a charge that covers the Trustee’s actual costs.

The Trustee, upon the written request of the Master Servicer, shall execute and deliver to the related Servicer and the Master Servicer any court pleadings, requests for trustee’s sale or other documents necessary or desirable to (i) the foreclosure or trustee’s sale with respect to a Mortgaged Property; (ii) any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage; (iii) obtain a deficiency judgment against the Mortgagor; or (iv) enforce any other rights or remedies provided by the Mortgage Note or Mortgage or otherwise available at law or equity.

SECTION 3.02. REMIC-Related Covenants.

For as long as each REMIC created hereunder shall exist, the Trustee and the Securities Administrator shall act in accordance herewith to treat each such REMIC as a REMIC, and the Trustee and the Securities Administrator shall comply with any directions of the Depositor, the related Servicer or the Master Servicer to assure such continuing treatment. In particular, the Trustee, the Securities Administrator and the Master Servicer shall not (a) sell or knowingly permit the sale of all or any portion of the Mortgage Loans or of any investment of deposits in an Account unless such sale is as a result of a repurchase of the Mortgage Loans or is otherwise permitted pursuant to this Agreement or the Trustee has received a REMIC Opinion prepared at the expense of the Trust; and (b) other than with respect to a substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.03 or 2.04 of this Agreement or as otherwise provided in this Agreement, as applicable, accept any contribution to any REMIC after the Startup Day without receipt of a REMIC Opinion.

SECTION 3.03. Monitoring of Servicers.

(a)

The Master Servicer shall be responsible for reporting to the Trustee (on behalf of the Trust) and the Depositor the compliance by each Servicer with its duties under the related Servicing Agreement. In the review of each Servicer’s activities, the Master Servicer may rely upon an officer’s certificate of the Servicer with regard to such Servicer’s compliance with the terms of its Servicing Agreement. In the event that the Master Servicer, in its judgment, determines that a Servicer should be terminated in accordance with its Servicing Agreement, or that a notice should be sent pursuant to such Servicing Agreement with respect to the occurrence of an event that, unless cured, would constitute grounds for such termination, the Master Servicer shall notify the Depositor and the Trustee thereof and the Master Servicer shall issue such notice or take such other action as it deems appropriate.

(b)

The Master Servicer, for the benefit of the Trust and the Certificateholders, shall (acting as agent of the Trust when enforcing the Trust’s rights under each Servicing Agreement) (i) enforce the obligations of each Servicer under the related Servicing Agreement, and (ii) in the event that a Servicer fails to perform its obligations in accordance with the related Servicing Agreement, subject to the preceding paragraph, terminate the rights and obligations of such Servicer thereunder and act as servicer of the related Mortgage Loans or enter into a new Servicing Agreement with a successor Servicer selected by the Master Servicer which the Master Servicer shall cause the Trustee to acknowledge; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to such 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, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action.

(c)

To the extent that the costs and expenses of the Master Servicer related to any termination of a Servicer, appointment of a successor Servicer or the transfer and assumption of servicing by the Master Servicer with respect to any Servicing Agreement (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the Servicer as a result of an event of default by such Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor servicer to service the Mortgage Loans in accordance with the related Servicing Agreement) are not fully and timely reimbursed by the terminated Servicer, the Master Servicer shall be entitled to reimbursement of such costs and expenses from the Distribution Account.

(d)

The Master Servicer shall require each Servicer to comply with the remittance requirements and other obligations set forth in the related Servicing Agreement.

(e)

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.

(f)

With respect to Additional Collateral Mortgage Loans, the Master Servicer shall have no duty or obligation to supervise, monitor or oversee the activities of each Servicer under its Servicing Agreement with respect to Additional Collateral, except (a) with respect to any instances where a Servicer, in the course of fulfilling its obligations under the related Servicing Agreement seeks directions, instructions, consents or waivers from the Master Servicer with respect to any item of Additional Collateral, or (b) upon the occurrence of the following events (i) in the case of a final liquidation of any Mortgaged Property secured by Additional Collateral, the Master Servicer shall enforce the obligation of the Servicer under the related Servicing Agreement to liquidate such Additional Collateral as required by such Servicing Agreement, and (ii) if the Master Servicer assumes the obligations of such Servicer as successor Servicer under the related Servicing Agreement pursuant to this Section 3.03, as successor Servicer, it shall be bound to service and administer the Additional Collateral in accordance with the provisions of such Servicing Agreement.

SECTION 3.04. Fidelity Bond.

The Master Servicer, at its expense, shall maintain in effect a blanket 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 generally acceptable for entities serving as master servicers or trustees.

SECTION 3.05. Power to Act; Procedures.

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, to do any and all things that it may deem necessary or desirable in connection with the master 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, the Trust 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, Liquidation Proceeds and Recoveries and (iv) to effectuate, in its own name, on behalf the Trust, or in the name of the Trust, 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 related Servicing Agreement, as applicable; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 3.03, shall not permit any Servicer to) knowingly or intentionally take any action, or fail to take (or fail to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, would result in an Adverse REMIC Event unless the Master Servicer has received an Opinion of Counsel (but not at the expense of the Master Servicer) to the effect that the contemplated action will not result in an Adverse REMIC Event. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any limited powers of attorney empowering the Master Servicer or any Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, 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 Master Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Master Servicer or any Servicer). In instituting foreclosures or similar proceedings, the Master Servicer shall institute such proceedings either in its own name on behalf of the Trust or in the name of the Trust (or cause the related Servicer, pursuant to the related Servicing Agreement, to institute such proceedings either in the name of such Servicer on behalf of the Trust or in the name 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 Trust or the Trustee on its behalf or that the Trust or the Trustee, as applicable, would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, the Master Servicer shall join with the Trustee, on behalf of the Trust, in the appointment of a co-trustee pursuant to Section 8.10 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 on behalf of the Trust.

SECTION 3.06. Due-on-Sale Clauses; Assumption Agreements.

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

SECTION 3.07. Release of Mortgage Files.

(a)

Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by any Servicer of a notification that payment in full has been escrowed in a manner customary for such purposes for payment to Certificateholders on the next Distribution Date, the Servicer will, if required under the applicable Servicing Agreement, promptly furnish to the Custodian, on behalf of the Trustee, two copies of a certification substantially in the form of Exhibit F hereto signed by a Servicing Officer or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer (which certification shall include a statement to the effect that all amounts received in connection with such payment that are required to be deposited in the related Servicing Account maintained by the applicable Servicer pursuant to Section 4.01 or by the applicable Servicer pursuant to its Servicing Agreement have been or will be so deposited) and shall request that the Trustee (or the Custodian, on behalf of the Trustee) deliver to the applicable Servicer the related Mortgage File. Upon receipt of such certification and request, the Trustee (or the Custodian, on behalf of the Trustee), shall promptly release the related Mortgage File to the applicable Servicer and the Trustee (and the Custodian, if applicable) shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, each Servicer is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the related Servicing Account.

(b)

From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan and in accordance with the applicable Servicing Agreement, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by a Servicer or the Master Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Trustee (or the Custodian, on behalf of the Trustee), shall, upon the request of a Servicer or the Master Servicer, and delivery to the Trustee (the Custodian, on behalf of the Trustee), of two copies of a request for release signed by a Servicing Officer substantially in the form of Exhibit F (or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer), release the related Mortgage File held in its possession or control to the Servicer or the Master Servicer, as applicable. Such trust receipt shall obligate the Servicer or the Master Servicer to return the Mortgage File to the Trustee (or the Custodian on behalf of the Trustee) when the need therefor by the Servicer or the Master Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that hereinabove specified, the Mortgage File shall be released by the Trustee (or the Custodian on behalf of the Trustee), to the Servicer or the Master Servicer.

SECTION 3.08. Documents, Records and Funds in Possession of Master Servicer To Be Held for Trust.

(a)

The Master Servicer shall transmit and each Servicer (to the extent required by the related Servicing Agreement) shall transmit to the Trustee (or Custodian) 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 in the case of the Servicers, the applicable Servicing Agreement, to be delivered to the Trustee (or Custodian). Any funds received by the Master Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer or by a Servicer as Liquidation Proceeds, Insurance Proceeds or Recoveries in respect of any Mortgage Loan shall be held for the benefit of the Trust and the Certificateholders subject to the Master Servicer’s right to retain or withdraw from the Distribution Account the Master Servicing Fee, any additional compensation pursuant to Section 3.14 and any other amounts provided in this Agreement, and to the right of each Servicer to retain its Servicing Fee and any other amounts as provided in the applicable Servicing Agreement. The Master Servicer shall, and (to the extent provided in the applicable Servicing Agreement) shall 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, in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, Insurance Proceeds or Recoveries, shall be held by the Master Servicer for and on behalf of the Trust and the Certificateholders and shall be and remain the sole and exclusive property of the Trust; 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.

SECTION 3.09. Standard Hazard Insurance and Flood Insurance Policies.

(a)

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

(b)

Pursuant to Section 4.01 and 4.02, any amounts collected by the Servicers or the Master Servicer, or by any Servicer, under any insurance policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or released to the Mortgagor in accordance with the applicable Servicing Agreement) shall be deposited into the Distribution Account, subject to withdrawal pursuant to Section 4.02 and 4.03. Any cost incurred by the Master Servicer or any Servicer in maintaining any such insurance if the Mortgagor defaults in its obligation to do so shall be added to the amount owing under the Mortgage Loan where the terms of the Mortgage Loan so permit; provided, however, that the addition of any such cost shall not be taken into account for purposes of calculating the distributions to be made to Certificateholders and shall be recoverable by the Master Servicer or such Servicer pursuant to Section 4.02 and 4.03.

SECTION 3.10. Presentment of Claims and Collection of Proceeds.

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

SECTION 3.11. Maintenance of the Primary Insurance Policies.

(a)

The Master Servicer shall not take, or permit any Servicer (to the extent such action is prohibited under the applicable Servicing Agreement) to take, any action that would result in noncoverage under any applicable Primary Insurance Policy of any loss which, but for the actions of such Master Servicer or Servicer, would have been covered thereunder. The Master Servicer shall use its best reasonable efforts to cause each Servicer (to the extent required under the related Servicing Agreement) 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 (including any lender-paid Primary Insurance Policy) in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable. The Master Servicer shall not, and shall not permit any Servicer (to the extent required under the related Servicing Agreement) to, cancel or refuse to renew any such Primary Insurance Policy that is in effect at the date of the initial issuance of the Mortgage Note and is required to be kept in force hereunder except in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable.

(b)

The Master Servicer agrees to cause each Servicer (to the extent required under the related Servicing Agreement) to present, on behalf of the Trustee, the Trust and the Certificateholders, claims to the insurer under any Primary Insurance Policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Primary Insurance Policies respecting defaulted Mortgage Loans. Pursuant to Section 4.01 and 4.02, any amounts collected by the Servicer under any Primary Insurance Policies shall be deposited in the Distribution Account, subject to withdrawal pursuant to Section 4.03.

SECTION 3.12. Trustee to Retain Possession of Certain Insurance Policies and Documents.

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

SECTION 3.13. Realization Upon Defaulted Mortgage Loans.

The Master Servicer shall cause each Servicer (to the extent required under the related Servicing Agreement) to foreclose upon, repossess or otherwise comparably convert the ownership of Mortgaged Properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments, all in accordance with the applicable Servicing Agreement.

SECTION 3.14. Additional Compensation to the Master Servicer.

Pursuant to Section 4.02(c), certain income and gain realized from any investment of funds in the Distribution Account shall be for the benefit of the Master Servicer as additional compensation. Servicing compensation in the form of assumption fees, if any, late payment charges, as collected, if any, or otherwise (but, unless otherwise specifically permitted in a Servicing Agreement, not including any Prepayment Penalty Amounts) shall be retained by the applicable Servicer, or the Master Servicer, and shall not be deposited in the related Servicing Account or Distribution Account. The Master Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor except as provided in this Agreement. The amount of the aggregate compensation payable as set forth in this Section 3.14 plus the Master Servicing Fee due to the Master Servicer in respect of any Distribution Date shall be reduced in accordance with Section 5.06.

SECTION 3.15. REO Property.

(a)

In the event the Trust (or the Trustee on its behalf) acquires ownership of any REO Property in respect of any related Mortgage Loan, the deed or certificate of sale shall be issued to the Trust, or if required under applicable law, to the Trustee, or to its nominee, on behalf of the Trust. The Master Servicer shall, to the extent provided in the applicable Servicing Agreement, cause the applicable Servicer to sell, any REO Property as expeditiously as possible (and in no event later than three years after acquisition) and in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable. Pursuant to its efforts to sell such REO Property, the Master Servicer shall cause the applicable Servicer to protect and conserve, such REO Property in the manner and to the extent required by the applicable Servicing Agreement, in accordance with the REMIC Provisions and in a manner that does not result in a tax on “net income from foreclosure property” or cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code.

(b)

The Master Servicer shall, to the extent required by the related Servicing Agreement, cause the applicable Servicer to deposit all funds collected and received in connection with the operation of any REO Property in the related Servicing Account.

(c)

The Master Servicer and the applicable Servicer, upon the final disposition of any REO Property, shall be entitled to reimbursement for any related unreimbursed Advances and other unreimbursed advances as well as any unpaid Servicing Fees from Liquidation Proceeds received in connection with the final disposition of such REO Property; provided, that any such unreimbursed Advances as well as any unpaid Servicing Fees may be reimbursed or paid, as the case may be, prior to final disposition, out of any net rental income or other net amounts derived from such REO Property.

(d)

To the extent provided in the related Servicing Agreement, the Liquidation Proceeds from the final disposition of the REO Property, net of any payment to the Master Servicer and the applicable Servicer as provided above shall be deposited in the related Servicing Account on or prior to the applicable Determination Date in the month following receipt thereof and be remitted by wire transfer in immediately available funds to the Master Servicer for deposit into the related Distribution Account on the next succeeding Servicer Remittance Date.

When the Master Servicer, the Custodian, and the Securities Administrator submit their assessments to the Securities Administrator, such parties will also at such time include the assessment (and attestation pursuant to subsection (b) of this Section 3.16) of each Servicing Function Participant engaged by it.

(iii)

Promptly after receipt of each such report on assessment of compliance, (i) the Depositor shall review each such report and, if applicable, consult with the Master Servicer, the Securities Administrator, the Custodian, and any Servicing Function Participant engaged by such parties as to the nature of any material instance of noncompliance with the Relevant Servicing Criteria by each such party, and (ii) the Securities Administrator shall confirm that the assessments, taken as a whole, address all of the Servicing Criteria and taken individually address the Relevant Servicing Criteria for each party as set forth on Exhibit Q and on any similar exhibit set forth in each Servicing Agreement in respect of each Servicer and notify the Depositor of any exceptions. None of the parties shall be required to deliver any such assessments until March 30 in any given year so long as it has received written confirmation from the Depositor that a Form 10-K is not required to be filed in respect of the Trust for the preceding calendar year; provided that the Custodian shall only be required to deliver such an assessment of compliance with respect to any fiscal year for which a Form 10-K is required to be filed in respect of the Trust. The Master Servicer shall include all annual reports on assessment of compliance received by it with its own assessment of compliance to be submitted to the Securities Administrator pursuant to this Section.

In the event the Master Servicer, the Securities Administrator or the Custodian or any Servicing Function Participant engaged by any such party is terminated, assigns its rights and obligations under, or resigns pursuant to, the terms of this Agreement, or any other applicable agreement, as the case may be, such party shall provide or shall cause such Servicing Function Participant to provide for the applicable period preceding such assignment and termination a report on assessment of compliance pursuant to this Section 3.16(a) or to such other applicable agreement, notwithstanding any such termination, assignment or resignation.

In the event that an overall opinion cannot be expressed, such registered public accounting firm shall state in such report why it was unable to express such an opinion. Such report must be available for general use and not contain restricted use language.

Promptly after receipt of each such Officer’s Certificate, the Depositor shall review such Officer’s Certificate and, if applicable, consult with each such party, as applicable, as to the nature of any failures by such party, in the fulfillment of any of such party’s obligations hereunder or, in the case of any Servicing Function Participant, under such other applicable agreement.

Such officer of the Certifying Person can be contacted by e-mail at xxx.xxx.xxxxxxxxxxxxx@xxxxxxxxxx.xxx or by facsimile at 000-000-0000. In the event any such party or any Servicing Function Participant engaged by such party is terminated or resigns pursuant to the terms of this Agreement, or any applicable sub-servicing agreement, as the case may be, such party shall provide a Back-Up Certification to the Certifying Person pursuant to this Section 3.18 with respect to the period of time it was subject to this Agreement or any applicable sub-servicing agreement, as the case may be. Notwithstanding the foregoing, (i) the Master Servicer and the Securities Administrator shall not be required to deliver a Back-Up Certification to each other if both are the same Person and the Master Servicer is the Certifying Person and (ii) the Master Servicer shall not be obligated to sign the Xxxxxxxx-Xxxxx Certification in the event that it does not receive any Back-Up Certification required to be furnished to it pursuant to this section or any Servicing Agreement or Custodial Agreement.

(iii)

After preparing the Form 10-D, the Securities Administrator shall forward upon request electronically a copy of the Form 10-D to the Depositor (provided that such Form 10-D includes any Additional Form 10-D Disclosure). Within two Business Days after receipt of such copy, but no later than the 12^th calendar day after the Distribution Date, the Depositor shall notify the Securities Administrator in writing (which may be furnished electronically) of any changes to or approval of such Form 10-D.

A duly authorized representative of the Master Servicer shall sign each Form 10-D. If a Form 10-D cannot be filed on time or if a previously filed Form 10-D needs to be amended, the Securities Administrator will follow the procedures set forth in subsection (d)(ii) of this Section 3.19.

Principal payments received from the Final Maturity Reserve Trust shall not be treated as distributions from any REMIC created hereby.

Each Depository Participant shall only transfer Book-Entry Certificates of Certificate Owners that it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures. The parties hereto are hereby authorized to execute a Letter of Representations with the Depository or take such other action as may be necessary or desirable to register a Book-Entry Certificate to the Depository. In the event of any conflict between the terms of any such Letter of Representation and this Agreement, the terms of this Agreement shall control.

(c)

If (i)(x) the Depository or the Depositor advises the Trustee or the Securities Administrator in writing that the Depository is no longer willing or able to discharge properly its responsibilities as Depository and (y) the Trustee, the Securities Administrator or the Depositor is unable to locate a qualified successor or (ii) after the occurrence and continuation of an Event of Default, Holders of Book-Entry Certificates having not less than 51% of the aggregate Certificate Principal Balance of the Certificates advise the Trustee, the Securities Administrator and the Depository in writing through the Depository Participants that the continuation of a book-entry system with respect to Certificates through the Depository (or its successor) is no longer in the best interests of the Holders, then the Trustee or the Securities Administrator shall request that the Depository notify all Holders of the occurrence of any such event and of the availability of definitive, fully registered Certificates to Holders requesting the same. Upon surrender to the Certificate Registrar of the Book-Entry Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Securities Administrator shall, at the Seller’s expense, execute on behalf of the Trust and authenticate definitive, fully registered certificates (the “Definitive Certificates”). None of the Depositor, the Securities Administrator or the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates, the Trustee, the Securities Administrator, the Certificate Registrar, any Paying Agent and the Depositor shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder.

Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Securities Administrator, the Seller and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws. Notwithstanding the foregoing, any transfer made to Xxxxxxxxx or to another Affiliate of Xxxxxxxxx will not require any investment letter or Opinion of Counsel specified above.

Except for any transfer made to Xxxxxxxxx or to another Affiliate of Xxxxxxxxx, no transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate shall be made unless the Securities Administrator shall have received either (i) a representation from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Securities Administrator (such requirement is satisfied only by the Securities Administrator’s receipt of a representation letter from the transferee substantially in the form of Exhibit I hereto), to the effect that such transferee is not an employee benefit plan subject to Section 406 of ERISA or a plan or arrangement subject to Section 4975 of the Code, nor a person acting on behalf of any such plan or arrangement nor using the assets of any such plan or arrangement to effect such transfer or (ii) if the purchaser is an insurance company, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) an Opinion of Counsel satisfactory to the Securities Administrator, which Opinion of Counsel shall not be an expense of any of the Trustee, the Securities Administrator or the Trust, addressed to the Securities Administrator, to the effect that the purchase and holding of such ERISA-Restricted Certificate that is also a Physical Certificate will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code and will not subject the Trustee, the Master Servicer, any Servicer, the Securities Administrator or the Depositor to any obligation in addition to those expressly undertaken in this Agreement or to any liability. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Certificate that is also a Physical Certificate to an employee benefit plan subject to ERISA or Section 4975 of the Code without the delivery to the Securities Administrator of an Opinion of Counsel satisfactory to the Securities Administrator as described above shall be void and of no effect.

No transfer of an ERISA-Restricted Auction Certificate prior to the Auction Call or an ERISA-Restricted Final Maturity Reserve Certificate in the form of a Definitive Certificate shall be made unless the Securities Administrator shall have received either (i) a representation from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Securities Administrator and the Depositor (such requirement is satisfied only by the Securities Administrator’s receipt of a representation letter from the transferee substantially in the form of Exhibit I hereto), to the effect that such transferee is not acquiring such Certificate for, on behalf of, or with the assets of, an employee benefit plan or other retirement arrangement subject to Section 406 of ERISA or Section 4975 of the Code, or (ii) 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.

In the case of an ERISA-Restricted Auction Certificate or an ERISA-Restricted Final Maturity Reserve Certificate that is a Book-Entry Certificate, for purposes of the first sentence of the preceding paragraph, such representations shall be deemed to have been made to the Securities Administrator by the transferee’s acceptance of such Certificates that are also Book-Entry Certificates (or the acceptance by a Certificate Owner of the beneficial interest in such Certificates).

To the extent permitted under applicable law (including, but not limited to, ERISA), none of the Trustee, the Securities Administrator nor the Certificate Registrar shall have any liability to any Person for any registration of transfer of any ERISA-Restricted Certificate, ERISA-Restricted Auction Certificate or ERISA-Restricted Final Maturity Reserve Certificate that is in fact not permitted by this Section 6.02(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 or the Certificate Registrar in accordance with the foregoing requirements. In addition, none of the Trustee, the Securities Administrator nor the Certificate Registrar shall be required to monitor, determine or inquire as to compliance with the transfer restrictions with respect to any such Certificate in the form of a Book-Entry Certificate, and neither the Securities Administrator nor the Certificate Registrar shall have any liability for transfers of Book-Entry Certificates or any interests therein made in violation of the restrictions on transfer described in the Prospectus Supplement and this Agreement.

Upon notice by the Auction Administrator to the Securities Administrator that the Holder of any Auction Certificate not held in book-entry form has failed to surrender such Certificate for registration of transfer on the Auction Distribution Date, the Securities Administrator shall, upon request by the Auction Administrator, deem such Certificate cancelled and issue, authenticate and deliver, in the name of the transferee designated by the Auction Administrator, a new Certificate in a denomination of like Class Certificate Principal Balance.

(e)

Each Person who has or who acquires any Ownership Interest in the Class A-R Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions and to have irrevocably appointed the Depositor or its designee as its attorney-in-fact to negotiate the terms of any mandatory sale under clause (v) below and to execute all instruments of transfer and to do all other things necessary in connection with any such sale, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i)

Each Person holding or acquiring any Ownership Interest in a Class A-R Certificate shall be a Permitted Transferee who acquires such Ownership Interest in a Class A-R Certificate for its own account and not in the capacity as trustee, nominee or agent for another Person and shall promptly notify the Securities Administrator of any change or impending change in its status as such a Permitted Transferee.

(ii)

No Ownership Interest in the Class A-R Certificate may be registered on the Closing Date and no Ownership Interest in a Residual Certificate may thereafter be transferred, and the Securities Administrator shall not register the Transfer of a Residual Certificate unless, in addition to the certificates required to be delivered under subsection (d) above, the Securities Administrator shall have been furnished with an affidavit (“Transfer Affidavit”) of the initial owner of the Class A-R Certificate or proposed transferee of a Residual Certificate in the form attached hereto as Exhibit L.

(iii)

In connection with any proposed transfer of any Ownership Interest in a Residual Certificate, the Securities Administrator shall as a condition to registration of the transfer, require delivery to it of a Transferor Certificate in the form of Exhibit K hereto from the proposed transferor to the effect that the transferor (a) has no knowledge the proposed Transferee is not a Permitted Transferee acquiring an Ownership Interest in such Class A-R Certificate for its own account and not in a capacity as trustee, nominee, or agent for another Person, and (b) has not undertaken the proposed transfer in whole or in part to impede the assessment or collection of tax.

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section shall be absolutely null and void and shall vest no rights in the purported transferee. If any purported transferee shall, in violation of the provisions of this Section, become a Holder of such Residual Certificate, then the prior Holder of such Residual Certificate that is a Permitted Transferee shall, upon discovery that the registration of Transfer of such Residual Certificate was not in fact permitted by this Section, be restored to all rights as Holder thereof retroactive to the date of registration of transfer of such Residual Certificate. None of the Trustee, the Securities Administrator or the Certificate Registrar shall have any liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by this Section or for making any distributions due on a Residual Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as, with respect to the Securities Administrator, it has received the documents specified in clause (iii). The Securities Administrator shall be entitled to recover from any Holder of such Residual Certificate that was in fact not a Permitted Transferee at the time such distributions were made all distributions made on such Residual Certificate. Any such distributions so recovered by the Securities Administrator shall be distributed and delivered by the Securities Administrator to the last Holder of such Residual Certificate that is a Permitted Transferee.

(v)

If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section, then the Securities Administrator shall have the right but not the obligation, without notice to the Holder of such Residual Certificate or any other Person having an Ownership Interest therein, to notify the Depositor to arrange for the sale of such Residual Certificate. The proceeds of such sale, net of commissions (which may include commissions payable to the Depositor or its affiliates in connection with such sale), expenses and taxes due, if any, will be remitted by the Securities Administrator to the previous Holder of such Residual Certificate that is a Permitted Transferee, except that in the event that the Securities Administrator determines that the Holder of such Residual Certificate may be liable for any amount due under this Section or any other provisions of this Agreement, the Securities Administrator may withhold a corresponding amount from such remittance as security for such claim. The terms and conditions of any sale under this clause (v) shall be determined in the sole discretion of the Securities Administrator and it shall not be liable to any Person having an Ownership Interest in such Residual Certificate as a result of its exercise of such discretion.

(vi)

If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section, then the Securities Administrator upon receipt of reasonable compensation will provide to the Internal Revenue Service, and to the persons specified in Sections 860E(e)(3) and (6) of the Code, information needed to compute the tax imposed under Section 860E(e)(5) of the Code on transfers of residual interests to disqualified organizations.

The foregoing provisions of this Section shall cease to apply to transfers occurring on or after the date on which there shall have been delivered to the Trustee, the Securities Administrator and the Servicer, in form and substance satisfactory to the Trustee and the Securities Administrator, (i) written notification from each Rating Agency that the removal of the restrictions on Transfer set forth in this Section will not cause such Rating Agency to downgrade its ratings of the Certificates and (ii) an Opinion of Counsel to the effect that such removal will not cause either REMIC created hereunder to fail to qualify as a REMIC.

(f)

No service charge shall be made for any registration of transfer or exchange of Certificates of any Class, 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 transfer or exchange of Certificates.

All Certificates surrendered for registration of transfer or exchange shall be cancelled by the Certificate Registrar and disposed of pursuant to its standard procedures.

SECTION 6.03. Mutilated, Destroyed, Lost or Stolen Certificates.

If (i) any mutilated Certificate is surrendered to the Certificate Registrar or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (ii) there is delivered to the Trustee, the Securities Administrator, the Depositor and the Certificate Registrar such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee, the Securities Administrator or the Certificate Registrar that such Certificate has been acquired by a bona fide purchaser, the Trustee or the Securities Administrator shall execute on behalf of the Trust, 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 Percentage Interest. Upon the issuance of any new Certificate under this Section, the Trustee, the Securities Administrator or the Certificate Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee, the Securities Administrator and the Certificate Registrar) in connection therewith. Any duplicate Certificate issued pursuant to this Section, shall constitute complete and indefeasible evidence of ownership in the Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

SECTION 6.04. Persons Deemed Owners.

The Depositor, the Trustee, the Securities Administrator, the Certificate Registrar, any Paying Agent and any agent of the Depositor, the Certificate Registrar, any Paying Agent, the Securities Administrator or the Trustee may treat the Person, including a Depository, in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 5.01 hereof and for all other purposes whatsoever, and none of the Trust, the Trustee, the Securities Administrator, the Certificate Registrar, the Paying Agent or any agent of any of them shall be affected by notice to the contrary.

SECTION 6.05. Appointment of Paying Agent.

(a)

The Paying Agent shall make distributions to Certificateholders from the Distribution Account pursuant to Section 5.01 hereof. The duties of the Paying Agent may include the obligation to distribute statements and provide information to Certificateholders as required hereunder. The Paying Agent hereunder shall at all times be an entity duly incorporated and validly existing under the laws of the United States of America or any state thereof, authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authorities. The Paying Agent shall initially be the Securities Administrator. The Securities Administrator may appoint a successor to act as Paying Agent, which appointment shall be reasonably satisfactory to the Depositor.

(b)

The Trustee shall cause the 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 shall hold all sums, if any, held by it for payment to the Certificateholders in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to such Certificateholders and shall agree that it shall comply with all requirements of the Code regarding the withholding of payments in respect of federal income taxes due from Certificate Owners and otherwise comply with the provisions of this Agreement applicable to it.

SECTION 6.06. 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-1 and Class A-X-2 Certificates, the Class I Certificate or a Residual Certificate) shall be equal to the sum of (i) the Certificate Principal Balance of such Certificate and (ii) any accrued but unpaid interest thereon at the applicable Pass-Through Rate with respect thereto for such Distribution Date. The purchase price for the Class A-X-1 or Class A-X-2 Certificates shall be an amount equal to the sum of (x) any Interest Distributable Amounts due (after taking into account payments made on such date from Interest Distributable Amounts for the related Loan Group) on the Class A-X-1 and the Class A-X-2 Certificates, as applicable, 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-1 or Class A-X-2 Certificates, as applicable (such present value to be based on a discount rate that will approximate the expected yield to maturity of the Class A-X-1 or Class A-X-2 Certificates, as applicable). The purchase price for the Class I Certificate shall be $1.00. The purchase price for the Class A-R 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 Securities Administrator (with copies to the Rating Agencies and the Master Servicer) written notice, in the form of Exhibit O hereto, 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 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 6.06(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 6.06(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 Trustee, the Securities Administrator and the Master Servicer.

(c)

Notice of exercise of the Optional Securities Purchase Right under Section 6.06(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 A-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 6.06(c), be purchased on the applicable Distribution Date by TMI at the price specified in Section 6.06(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 deemed the sole Holder of the Offered Certificates (other than the Residual Certificates) and it shall either be the sole Holder of the Class A-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 (other than those Certificates held by TMI).

ARTICLE VII

DEFAULT

SECTION 7.01. Event of Default.

(a)

If any one of the following events (each, an “Event of Default”) shall occur and be continuing:

(i)

the failure by the Master Servicer to (A) make any Advance on the Business Day immediately preceding the related Distribution Date or (B) to deposit in the Distribution Account any deposit required to be made under the terms of this Agreement, and in either case such failure continues unremedied for a period of three Business Days after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer (or, if applicable, such shorter time period as is provided in the penultimate sentence of Section 7.01(c)); or

(ii)

the failure by the Master Servicer duly to observe or perform, in any material respect, any other covenants, obligations or agreements of the Master Servicer as set forth in this Agreement, which failure continues unremedied for a period of 60 days, in each case after the date (A) on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Trustee or to the Master Servicer and the Trustee by Holders of Certificates evidencing at least 25% of the Voting Rights or (B) on which a Servicing Officer of the Master Servicer has actual knowledge of such failure (or, in the case of a breach of its obligation beyond any applicable cure period to provide an assessment of compliance, an attestation report or a Xxxxxxxx-Xxxxx Certification pursuant to Sections 3.16 and 3.18, respectively); or

(iii)

the entry against the Master Servicer of a decree or order by a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a trustee, conservator, receiver or liquidator in any insolvency, conservatorship, receivership, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 days; or

(iv)

the Master Servicer shall voluntarily go into liquidation, consent to the appointment of a conservator or receiver or liquidator or similar person in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to the Master Servicer or of or relating to all or substantially all of its property; or a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a conservator, receiver, liquidator or similar person in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged, unbonded or unstayed for a period of 60 days; or 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;

(b)

then, and in each and every such case, so long as an Event of Default shall not have been remedied within the applicable grace period, the Trustee shall, at the written direction of the Holders of Certificates evidencing Voting Rights aggregating not less than 51%, or at its option may, with the consent of Xxxxxxxxx (not to be unreasonably withheld), by notice then given in writing to the Master Servicer, terminate all of the rights and obligations of the Master Servicer as servicer under this Agreement. Any such notice to the Master Servicer shall also be given to each Rating Agency, the Depositor and the Seller. On or after the receipt by the Master Servicer (and by the Trustee if such notice is given by the Holders) of such written notice, all authority and power of the Master Servicer under this Agreement, whether with respect to the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee and the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement of each Mortgage Loan and related documents or otherwise. The Master Servicer agrees to cooperate with the Trustee in effecting the termination of the responsibilities and rights of the Master Servicer hereunder, including, without limitation, the delivery to the Trustee of all documents and records requested by it to enable it to assume the Master Servicer's functions under this Agreement within ten Business Days subsequent to such notice and the transfer within one Business Day subsequent to such notice to the Trustee for the administration by it of all cash amounts that shall at the time be held by the Master Servicer and to be deposited by it in the Distribution Account, any REO Account or any Servicing Account or that have been deposited by the Master Servicer in such accounts or thereafter received by the Master Servicer with respect to the Mortgage Loans or any REO Property received by the Master Servicer. All reasonable costs and expenses (including attorneys' fees) incurred in connection with transferring the Master Servicer's duties and the Mortgage Files to the successor Master Servicer and amending this Agreement to reflect such succession as Master Servicer pursuant to this Section shall be paid by the predecessor Master Servicer (or if the predecessor Master Servicer is the Trustee, the initial Master Servicer) upon presentation of reasonable documentation of such costs and expenses. The termination of the rights and obligations of the Master Servicer shall not affect any liability it may have incurred prior to such termination. 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.

(c)

The Securities Administrator shall not later than the close of business on the Business Day immediately preceding the related Distribution Date notify the Trustee in writing of the Master Servicer’s failure to make any Advance required to be made under this Agreement on such 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 or that the Master Servicer has made the Advance, as the case may be. Notwithstanding the terms of the Event of Default described in clause (i)(A) of Section 7.01(a), the Trustee, upon receipt of written notice on the Distribution Date from the Securities Administrator of the continuance of the failure of the Master Servicer to make an Advance, shall, by notice in writing to the Master Servicer, which may be delivered by telecopy, immediately suspend all of the rights and obligations of the Master Servicer thereafter arising under this Agreement, but without prejudice to any rights it may have as a Certificateholder or to reimbursement of outstanding Advances or other amounts for which the Master Servicer was entitled to reimbursement as of the date of suspension, and the Trustee, subject to the cure provided for in this paragraph, if available, shall act as provided in Section 7.02 to carry out the duties of the Master Servicer, including the obligation to make any Advance the nonpayment of which is described in clause (i)(A) of Section 7.01(a). Any such action taken by the Trustee must be prior to the distribution on the relevant Distribution Date, and shall have all of the rights incidental thereto. If the Master Servicer shall within two Business Days following such suspension remit to the Trustee the amount of any Advance the nonpayment of which by the Master Servicer is described in clause (i)(A) of Section 7.01(a), together with all other amounts necessary to reimburse the Trustee for actual, necessary and reasonable costs incurred by the Trustee because of action taken pursuant to this subsection (including interest on any Advance or other amounts paid by the Trustee (from and including the respective dates thereof) at a per annum rate equal to the prime rate for U.S. money center commercial banks as published in the Wall Street Journal), then the Trustee, subject to the last two sentences of this paragraph, shall permit the Master Servicer to resume its rights and obligations as Master Servicer hereunder. If the Master Servicer shall fail to remit such amounts to the Trustee within such two Business Days after the Distribution Date, then an Event of Default shall occur and such notice of suspension shall be deemed to be a notice of termination without any further action on the part of the Trustee. The Master Servicer agrees that if it fails to make a required Advance by 10:00 A.M. (Chicago time) on the related Distribution Date on more than two occasions in any 12 month period, the Trustee shall be under no obligation to permit the Master Servicer to resume its rights and obligations as Master Servicer hereunder, and notwithstanding the cure period provided in Section 7.01(a)(i)(A), an Event of Default shall be deemed to have occurred on the relevant Distribution Date.

SECTION 7.02. Trustee to Act.

(a)

From and after the date the Master Servicer (and the Trustee, if notice is sent by the Holders) receives a notice of termination pursuant to Section 7.01, the Trustee shall be the successor in all respects to the Master Servicer in its capacity as servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof arising on and after its succession. As compensation therefor, the Trustee shall be entitled to such compensation as the Master Servicer would have been entitled to hereunder if no such notice of termination had been given. Notwithstanding the above, (i) if the Trustee is unwilling to act as successor Master Servicer or (ii) if the Trustee is legally unable so to act, subject to the rights of Xxxxxxxxx under Section 3.33 hereof, the Trustee shall appoint or petition a court of competent jurisdiction to appoint, any established housing and home finance institution, bank or other mortgage loan or home equity loan servicer having a net worth of not less than $15,000,000 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 appointment of any such successor Master Servicer shall not result in the qualification, reduction or withdrawal of the ratings assigned to the Certificates by each Rating Agency as evidenced by a letter to such effect from each Rating Agency. Pending appointment of a successor to the Master Servicer hereunder, unless the Trustee is prohibited by law from so acting, the Trustee shall act in such capacity as hereinabove provided. In connection with such appointment and assumption, the successor shall be entitled to receive compensation out of payments on Mortgage Loans in an amount equal to the compensation which the Master Servicer would otherwise have received pursuant to Section 3.18. The appointment of a successor Master Servicer shall not affect any liability of the predecessor Master Servicer which may have arisen under this Agreement prior to its termination as Master Servicer to pay any deductible under an insurance policy pursuant to Section 3.14 or to indemnify the Trustee pursuant to Section 8.05), nor shall any successor Master Servicer be liable for any acts or omissions of the predecessor Master Servicer or for any breach by such Master Servicer of any of its representations or warranties contained herein or in any related document or agreement. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. In the event that the Trustee shall not succeed to the duties of the Master Servicer pursuant to Section 7.02 hereof, Xxxxxxxxx shall have the right, but not the obligation, to be appointed successor master servicer hereunder.

(b)

Any successor, including the Trustee, to the Master Servicer as Master Servicer shall during the term of its service as Master Servicer continue to service and administer the Mortgage Loans for the benefit of Certificateholders, and maintain in force a policy or policies of insurance covering errors and omissions in the performance of its obligations as Master Servicer hereunder and a Fidelity Bond in respect of its officers, employees and agents to the same extent as the Master Servicer is so required pursuant to Section 3.04.

(c)

Notwithstanding anything else herein to the contrary, in no event shall the Trustee be liable for any servicing fee or for any differential in the amount of the servicing fee paid hereunder and the amount necessary to induce any successor Master Servicer to act as successor Master Servicer under this Agreement and the transactions set forth or provided for herein.

SECTION 7.03. Waiver of Event of Default.

The Majority Certificateholders may, on behalf of all Certificateholders, by notice in writing to the Trustee, direct the Trustee to waive any events permitting removal of any Master Servicer under this Agreement, provided, however, that the Majority Certificateholders may not waive an event that results in a failure to make any required distribution on a Certificate without the consent of the Holder of such Certificate. Upon any waiver of an Event of Default, such event shall cease to exist and any Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other event or impair any right consequent thereto except to the extent expressly so waived. Notice of any such waiver shall be given by the Trustee to each Rating Agency.

SECTION 7.04. Notification to Certificateholders.

(a)

Upon any termination or appointment of a successor to any Master Servicer pursuant to this Article VII or Section 3.34, the Certificate Registrar or the Trustee, if the Master Servicer is also the Certificate Registrar and Securities Administrator, shall give prompt written notice thereof to the Certificateholders at their respective addresses appearing in the Certificate Register and to each Rating Agency.

(b)

No later than 60 days after the occurrence of any event which constitutes or which, with notice or a lapse of time or both, would constitute an Event of Default of which a Responsible Officer of the Trustee becomes aware of the occurrence of such an event, the Trustee shall transmit by mail to all Certificateholders notice of such occurrence unless such Event of Default shall have been waived or cured.

ARTICLE VIII

THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

SECTION 8.01. Duties of Trustee and Securities Administrator.

The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default which may have occurred, and the Securities Administrator each undertake to perform such duties and only such duties as are specifically set forth in this Agreement. If an Event of Default has occurred (which has not been cured or waived) of which a Responsible Officer has actual knowledge, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs, unless the Trustee is acting as successor Master Servicer, in which case it shall use the same degree of care and skill as the Master Servicer hereunder with respect to the exercise of the rights and powers of the Master Servicer hereunder.

The Trustee and the Securities Administrator, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee and the Securities Administrator, which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they conform to the requirements of this Agreement; provided, however, that neither the Trustee nor the Securities Administrator will be responsible for the accuracy or content of any such resolutions, certificates, statements, opinions, reports, documents or other instruments. If any such instrument is found not to conform to the requirements of this Agreement in a material manner the Trustee and the Securities Administrator shall take such action as it deems appropriate to have the instrument corrected.

On each Distribution Date, the Securities Administrator shall make monthly distributions, to the Final Maturity Reserve Account (commencing with the Distribution Date in March 2016), the Yield Maintenance Account and to the Certificateholders from funds in the Distribution Account, in each case as provided in Sections 5.01, 5.09, 5.11 and 10.01 hereof based on the report of the Securities Administrator.

No provision of this Agreement shall be construed to relieve the Trustee or the Securities Administrator from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that:

(i)

prior to the occurrence of an Event of Default, and after the curing of all such Events of Default which may have occurred, the duties and obligations of the Trustee and the Securities Administrator shall be determined solely by the express provisions of this Agreement, neither the Trustee nor the Securities Administrator shall be liable except for the performance of such of its duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee or the Securities Administrator and, in the absence of bad faith on the part of the Trustee or the Securities Administrator, respectively, the Trustee or the Securities Administrator may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee or the Securities Administrator, respectively, and conforming to the requirements of this Agreement;

(ii)

neither the Trustee nor the Securities Administrator shall be liable for an error of judgment made in good faith by a Responsible Officer of the Trustee or an officer of the Securities Administrator, respectively, unless it shall be proved that the Trustee or the Securities Administrator, respectively, was negligent in ascertaining or investigating the facts related thereto;

(iii)

neither the Trustee nor the Securities Administrator shall be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the consent or at the direction of Holders of Certificates as provided herein relating to the time, method and place of conducting any remedy pursuant to this Agreement, or exercising or omitting to exercise any trust or power conferred upon the Trustee or the Securities Administrator, respectively, under this Agreement; and

(iv)

the Trustee shall not be charged with knowledge of any Event of Default or any other event or matter that may require it to take action or omit to take action hereunder unless a Responsible Officer of the Trustee at the Corporate Trust Office obtains actual knowledge of such failure or the Trustee receives written notice of such Event of Default.

Neither the Trustee nor the Securities Administrator shall be required to expend or risk its own funds or otherwise incur financial or other liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured to it, and none of the provisions contained in this Agreement shall in any event require the Trustee or the Securities Administrator to perform, or be responsible for the manner of performance of, any of the obligations of the Master Servicer under this Agreement, except during such time, if any, as the Trustee shall be the successor to, and be vested with the rights, duties, powers and privileges of, the Master Servicer in accordance with the terms of this Agreement.

SECTION 8.02. Certain Matters Affecting the Trustee and the Securities Administrator.

SECTION 8.07. Resignation or Removal of Trustee and Securities Administrator.

The Trustee and Securities Administrator may at any time resign and be discharged from the trusts hereby created by giving written notice thereof to the Depositor, the Seller, the Master Servicer and each Rating Agency. Upon receiving such notice of resignation of the Trustee, the Seller shall promptly appoint a successor Trustee that meets the requirements in Section 8.06 or, in the case of notice of resignation of the Securities Administrator, the Trustee shall promptly appoint a successor Securities Administrator that meets the requirements in Section 8.06, in each case, by written instrument, in duplicate, one copy of which instrument shall be delivered to each of the resigning Trustee or Securities Administrator, as applicable, and one copy to the successor Trustee or successor Securities Administrator, as applicable. If no successor Trustee or successor Securities Administrator, as applicable, shall have been so appointed and having accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee or Securities Administrator may petition any court of competent jurisdiction for the appointment of a successor Trustee or Securities Administrator, as applicable.

The Majority Certificateholders may at any time remove the Trustee or the Securities Administrator by written instrument or instruments delivered to the Seller and the Trustee; the Seller shall thereupon use its best efforts to appoint a successor Trustee or successor Securities Administrator, as applicable, in accordance with this Section.

Any resignation or removal of the Trustee or the Securities Administrator and appointment of a successor Trustee or a successor Securities Administrator, pursuant to any of the provisions of this Section 8.07 shall not become effective until acceptance of appointment by the successor Trustee or a successor Securities Administrator, as applicable, as provided in Section 8.08 hereof. If the Trustee or the Securities Administrator is removed pursuant to this Section 8.07, it shall be reimbursed any outstanding and unpaid fees and expenses, and if removed under the authority of the immediately preceding paragraph, the Trustee or the Securities Administrator shall also be reimbursed any outstanding and unpaid costs and expenses.

Notwithstanding anything to the contrary contained herein, in the event that the Master Servicer resigns or is removed as Master Servicer hereunder, the Securities Administrator shall have the right to resign immediately as Securities Administrator by giving written notice to the Seller and the Trustee, with a copy to each Rating Agency.

Any successor Trustee or successor Securities Administrator appointed as provided in Section 8.07 hereof shall execute, acknowledge and deliver to the Depositor, the Seller and the Master Servicer and to its predecessor Trustee or Securities Administrator an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee or Securities Administrator shall become effective, and such successor Trustee or successor Securities Administrator, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder (including, without limitation, with respect to such a successor Securities Administrator, its rights, powers, duties and obligations as Auction Administrator under the Auction Administration Agreement), with like effect as if originally named as Trustee or Securities Administrator. The Depositor, the Seller, the Master Servicer and the predecessor Trustee or Securities Administrator shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in the successor Trustee or Securities Administrator, as applicable, all such rights, powers, duties and obligations.

No successor Trustee or Securities Administrator shall accept appointment as provided in this Section 8.08 unless at the time of such acceptance such successor Trustee or Securities Administrator shall be eligible under the provisions of Section 8.06 hereof and the appointment of such successor Trustee or Securities Administrator shall not result in a downgrading of the Senior Certificates by either Rating Agency, as evidenced by a letter from each Rating Agency.

Upon acceptance of appointment by a successor Trustee or Securities Administrator as provided in this Section 8.08, the successor Trustee or Securities Administrator shall mail notice of the appointment of a successor Trustee or Securities Administrator hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register and to each Rating Agency.

SECTION 8.09. Merger or Consolidation of Trustee or Securities Administrator.

Any entity into which the Trustee or the Securities Administrator may be merged or converted or with which it may be consolidated, or any entity resulting from any merger, conversion or consolidation to which the Trustee or the Securities Administrator shall be a party, or any entity succeeding to the corporate trust business of the Trustee or the Securities Administrator, shall be the successor of the Trustee or the Securities Administrator, as applicable, hereunder, provided such entity shall be eligible under the provisions of Section 8.06 and 8.08 hereof, 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.

SECTION 8.10. Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, and in addition to the appointment of the Delaware Trustee pursuant to Section 1A.03 hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust or any Mortgaged Property may at the time be located, the Depositor and the Trustee acting jointly shall have the power, and the Trustee shall, and shall instruct the Depositor to, execute and deliver all instruments to appoint one or more Persons, approved by the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust, or any part thereof, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider necessary or desirable. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 hereof, and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 8.08 hereof.

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

(i)

all 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 or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer hereunder), 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 or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

(ii)

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

(iii)

the Depositor and the Trustee, acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee.

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 or co-trustee shall refer to this Agreement and the conditions of this Article VIII. 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 and a copy thereof given to the Depositor.

Any separate trustee or co-trustee 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 or co-trustee 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.

SECTION 8.11. Limitation of Liability.

The Certificates are executed by the Securities Administrator, not in its individual capacity but solely as Securities Administrator on behalf of the Trust, in the exercise of the powers and authority conferred and vested in it by this Agreement. Each of the undertakings and agreements made on the part of the Securities Administrator in the Certificates is made and intended not as a personal undertaking or agreement by the Trustee but is made and intended for the purpose of binding only the Trust.

SECTION 8.12. Trustee May Enforce Claims Without Possession of Certificates.

(a)

All rights of action and claims under this Agreement or the Certificates may be prosecuted and enforced by the Trustee without the possession of any of the Certificates or the production thereof in any proceeding relating thereto, and such proceeding instituted by the Trustee shall be brought in its own name or in its capacity as Trustee for the benefit of all Holders of such Certificates, subject to the provisions of this Agreement. Any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursement and advances of the Trustee (for the avoidance of doubt, in its individual capacity and as Trustee on behalf of the Trust), its agents and counsel, be for the ratable benefit or the Certificateholders in respect of which such judgment has been recovered.

(b)

The Trustee shall afford the Seller, the Depositor and each Certificateholder upon reasonable notice during normal business hours at its Corporate Trust Office or other office designated by the Trustee, access to all records maintained by the Trustee in respect of its duties hereunder and access to officers of the Trustee responsible for performing such duties. Upon request, the Trustee shall furnish the Depositor and any requesting Certificateholder with its most recent audited financial statements. The Trustee shall cooperate fully with the Seller, the Depositor and such Certificateholder and shall, subject to the first sentence of this Section 8.12(b), make available to the Seller, the Depositor and such Certificateholder for review and copying such books, documents or records as may be requested with respect to the Trustee’s duties hereunder. The Seller, the Depositor and the Certificateholders shall not have any responsibility or liability for any action or failure to act by the Trustee and are not obligated to supervise the performance of the Trustee under this Agreement or otherwise.

(c)

The Securities Administrator shall afford the Seller, the Depositor, the Trustee and each Certificateholder upon reasonable notice during normal business hours at its offices at 0000 Xxx Xxxxxxxxx Xxxx, Xxxxxxxx, Xxxxxxxx 00000 or other office designated by the Securities Administrator, access to all records maintained by the Securities Administrator in respect of its duties hereunder and access to officers of the Securities Administrator responsible for performing such duties. Upon request, the Securities Administrator shall furnish the Depositor and any requesting Certificateholder with its most recent audited financial statements. The Securities Administrator shall cooperate fully with the Seller, the Depositor, the Trustee and such Certificateholder and shall, subject to the first sentence of this Section 8.12(c), make available to the Seller, the Depositor and such Certificateholder for review and copying such books, documents or records as may be requested with respect to the Securities Administrator’s duties hereunder. The Seller, the Depositor, the Trustee and the Certificateholders shall not have any responsibility or liability for any action or failure to act by the Securities Administrator and are not obligated to supervise the performance of the Securities Administrator under this Agreement or otherwise.

SECTION 8.13. Suits for Enforcement.

In case an Event of Default or a default by the Depositor hereunder shall occur and be continuing, the Trustee may proceed to protect and enforce its rights and the rights of the Certificateholders under this Agreement, as the case may be, by a suit, action or proceeding in equity or at law or otherwise, whether for the specific performance of any covenant or agreement contained in this Agreement or in aid of the execution of any power granted in this Agreement or for the enforcement of any other legal, equitable or other remedy, as the Trustee, being advised by counsel, and subject to the foregoing, shall deem most effectual to protect and enforce any of the rights of the Trustee and the Certificateholders.

SECTION 8.14. Waiver of Bond Requirement.

The Trustee shall be relieved of, and each Certificateholder hereby waives, any requirement of any jurisdiction in which the Trust, or any part thereof, may be located that the Trustee post a bond or other surety with any court, agency or body whatsoever.

SECTION 8.15. Waiver of Inventory, Accounting and Appraisal Requirement.

The Trustee shall be relieved of, and each Certificateholder hereby waives, any requirement of any jurisdiction in which the Trust, or any part thereof, may be located that the Trustee file any inventory, accounting or appraisal of the Trust with any court, agency or body at any time or in any manner whatsoever.

SECTION 8.16. Appointment of Custodians.

The Trustee may appoint one or more custodians to hold all or a portion of the related Mortgage Files as agent for the Trustee, by entering into a custodial agreement.

Subject to this Article VIII, the Trustee agrees to comply with the terms of each custodial agreement and to enforce the terms and provisions thereof against the custodian for the benefit of the Certificateholders having an interest in any Mortgage File held by such custodian. Each custodian shall be a depository institution or trust company subject to supervision by federal or state authority, shall have combined capital and surplus of at least $15,000,000 and shall be qualified to do business in the jurisdiction in which it holds any Mortgage File. The Seller shall pay from its own funds, without any right to reimbursement, the fees, costs and expenses of each custodian (including the costs of custodian’s counsel).

SECTION 8.17. 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 1A.05 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 IX

REMIC ADMINISTRATION

SECTION 9.01. REMIC Administration.

(a)

As set forth in the Preliminary Statement to this Agreement, three REMIC elections shall be made by the Trust. The Trustee shall sign and the Securities Administrator shall file such elections on Form 1066 or other appropriate federal tax or information return for the taxable year ending on the last day of the calendar year in which the Certificates are issued. The regular interests in each REMIC created hereunder and the related residual interest shall be as designated in the Preliminary Statement. Following the Closing Date, the Securities Administrator shall apply to the Internal Revenue Service for an employer identification number for each REMIC created hereunder by means of a Form SS-4 or other acceptable method and shall file a Form 8811 with the Internal Revenue Service.

(b)

The Closing Date is hereby designated as the “Startup Day” of each REMIC created hereunder within the meaning of section 860G(a)(9) of the Code.

(c)

Except as provided in subsection (d) of this Section 9.01, the Securities Administrator shall pay any and all tax related expenses (not including taxes) of each REMIC created hereunder, including but not limited to any professional fees or expenses related to audits or any administrative or judicial proceedings with respect to any 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 the Securities Administrator’s duties as tax return preparer).

(d)

The Securities Administrator shall prepare and file, and the Trustee shall sign all of the federal and state tax and information returns of each REMIC created hereunder (collectively, the “Tax Returns”) as the direct representative. The expenses of preparing and filing such Tax Returns shall be borne by the Securities Administrator. Notwithstanding the foregoing, the Securities Administrator shall have no obligation to prepare, file or otherwise deal with partnership tax information or returns. In the event that partnership tax information or returns are required by the Internal Revenue Service, the Seller, at its own cost and expense, will prepare and file all necessary returns. The Internal Revenue Service has issued OID regulations under Sections 1271 to 1275 of the Code generally addressing the treatment of debt instruments issued with original issue discount. Under those regulations, debt issued to one Person generally is aggregated in determining if there is OID. Because certain Classes of Regular Certificates are expected to be issued to one Person (which intends to continue to hold the Regular Certificates indefinitely and, in any case, for at least 30 days), the Securities Administrator, on behalf of the Trust, intends to determine the existence and amount of any OID as if those Classes of Regular Certificates were one debt instrument.

(e)

The Securities Administrator shall perform on behalf of each REMIC created hereunder all reporting and other tax compliance duties that are the responsibility of each 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 the Class A-R Certificate to any disqualified 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)

Each of the Trustee, the Securities Administrator and the Holders of Certificates (to the extent that the affairs of the REMICs are within such Person’s control and the scope of its specific responsibilities under the Agreement) shall take any action or cause any REMIC created hereunder to take any action necessary to create or maintain the status of the REMIC created hereunder as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. None of the Trustee, the Securities Administrator or the Holder of a Residual Certificate shall take any action, cause any REMIC created hereunder to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could result in an Adverse REMIC Event unless the Trustee and the Securities Administrator have received an Opinion of Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not result in an Adverse REMIC Event. In addition, prior to taking any action with respect to any REMIC created hereunder or the assets therein, or causing any such REMIC to take any action which is not expressly permitted under the terms of this Agreement, any Holder of the Class A-R Certificate will consult with the Securities Administrator or its designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any such REMIC, and no such Person shall take any such action or cause any REMIC created hereunder to take any such action as to which the Securities Administrator has advised it in writing that an Adverse REMIC Event could occur.

(g)

Each Holder of the Class A-R Certificate shall pay when due any and all taxes imposed on any REMIC created hereunder by federal or state governmental authorities. To the extent that such Trust taxes are not paid by the Class A-R Certificateholder, the Securities Administrator shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Class A-R Certificate or, if no such amounts are available, out of other amounts held in the Distribution Account, and shall reduce amounts otherwise payable to holders of regular interests in such REMIC, as the case may be.

(h)

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

(i)

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

(j)

Neither the Trustee nor the Securities Administrator shall enter into any arrangement by which any REMIC created hereunder will receive a fee or other compensation for services.

(k)

The Securities Administrator shall treat 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 I Certificates and not assets of any REMIC. 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.

(l)

The Yield Maintenance Agreements and each of the Yield Maintenance Sub Accounts shall not be treated as an asset of any REMIC created hereunder. Instead, each owner of a Class A-1-A, Class A-1-B. Class A-1-C. and Class A-X-1 shall be treated as owning an interest in the Group 1 Yield Maintenance Agreement.

MISCELLANEOUS PROVISIONS

SECTION 12.01. Amendment.

This Agreement may be amended from time to time by Seller, the Depositor, the Master Servicer, the Securities Administrator, the Delaware Trustee and the Trustee, and without the consent of the Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any provisions herein which may be defective or inconsistent with any other provisions herein, (iii) to make any other provisions with respect to matters or questions arising under this Agreement, which shall not be inconsistent with the provisions of this Agreement, or (iv) to conform the terms hereof to the description thereof provided in the Prospectus; provided, however, that any such action listed in clause (i) through (iii) above shall be deemed not to adversely affect in any material respect the interests of any Certificateholder, if evidenced by (i) written notice to the Depositor, the Seller, the Master Servicer, the Securities Administrator, the Delaware Trustee and the Trustee from each Rating Agency that such action will not result in the reduction or withdrawal of the rating of any outstanding Class of Certificates with respect to which it is a Rating Agency or (ii) an Opinion of Counsel stating that such amendment shall not adversely affect in any material respect the interests of any Certificateholder, is permitted by the Agreement and all the conditions precedent, if any have been complied with, delivered to the Master Servicer, the Securities Administrator and the Trustee.

In addition, this Agreement may be amended from time to time by Seller, the Depositor, the Master Servicer, the Securities Administrator, the Delaware Trustee and the Trustee and with the consent of the Majority Certificateholders 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 of Certificates; provided, however, that no such amendment or waiver shall (x) reduce in any manner the amount of, or delay the timing of, payments on the Certificates that are required to be made on any Certificate without the consent of the Holder of such Certificate, (y) adversely affect in any material respect the interests of the Holders of any Class of Certificates in a manner other than as described in clause (x) above, without the consent of the Holders of Certificates of such Class evidencing at least a 66% Percentage Interest in such Class, or (z) reduce the percentage of Voting Rights required by clause (y) above without the consent of the Holders of all Certificates of such Class then outstanding. Upon approval of an amendment, a copy of such amendment shall be sent to each Rating Agency.

Notwithstanding any provision of this Agreement to the contrary, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel, delivered by and at the expense of the Person seeking such Amendment (unless such Person is the Trustee, in which case the Trustee shall be entitled to be reimbursed for such expenses by the Trust pursuant to Section 8.05 hereof), to the effect that such amendment will not result in the imposition of a tax on any REMIC created hereunder pursuant to the REMIC Provisions or cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding and that the amendment is being made in accordance with the terms hereof, such amendment is permitted by this Agreement and all conditions precedent, if any, have been complied with.

Promptly after the execution of any such amendment the Trustee shall furnish, at the expense of the Person that requested the amendment if such Person is the Seller (but in no event at the expense of the Trustee or the Securities Administrator), otherwise at the expense of the Trust, a copy of such amendment and the Opinion of Counsel referred to in the immediately preceding paragraph to the Master Servicer and each Rating Agency.

It shall not be necessary for the consent of Certificateholders under this Section 12.01 to approve the particular form of any proposed amendment; instead it shall be sufficient if such consent shall approve the substance thereof.

The Trustee and Securities Administrator may, but shall not be obligated to, enter into any amendment pursuant to this 12.01 Section that affects its rights, duties and immunities under this Agreement or otherwise.

SECTION 12.02. Recordation of Agreement; Counterparts.

COUNTY OF	)

The undersigned, being first duly sworn, deposes and says as follows:

The undersigned is an officer of ______________________, the proposed Transferee of a 100% Ownership Interest in the Class A-R Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement, (the “Agreement”), dated as of March 1, 2006, relating to the above-referenced Certificates, among Credit Suisse First Boston Mortgage Securities Corp., as Depositor, Xxxxxxxxx Mortgage Home Loans, Inc., as Seller, Xxxxx Fargo Bank, N.A., as Master Servicer, Wilmington Trust Company, as Delaware Trustee and LaSalle Bank National Association, as Trustee. Capitalized terms used, but not defined herein, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee.

The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest for its own account and not in a capacity as trustee, nominee or agent for another party.

The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are not Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is a Permitted Transferee and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false. The Transferee has provided financial statements or other financial information requested by the Transferor in connection with the transfer of the Certificate to permit the Transferor to assess the financial capability of the Transferee to pay such taxes.

The Transferee has been advised of, and understands that a tax may be imposed on a “pass-through entity” holding the Certificate if, at any time during the taxable year of the pass-through entity, a Disqualified Organization is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is not a Disqualified Organization and the pass-through entity does not have actual knowledge that such affidavit is false. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.)

The Transferee has reviewed the provisions of Section 6.02(e) of the Agreement and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 6.02(e) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a certificate substantially in the form set forth as Exhibit K to the Agreement (a “Transferor Certificate”).

The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Certificate.

The Transferee’s taxpayer identification number is .

The Transferee is aware that the Certificate may be a “noneconomic residual interest” within the meaning of the REMIC provisions and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax.

IN WITNESS WHEREOF, the Transferee has caused this instrument to be executed on its behalf, pursuant to authority of its Board of Directors, by its duly authorized officer and its corporate seal to be hereunto affixed, duly attested, this day of , 20 .
