If the weighted average of the Net Mortgage Rates on the Mortgage Loans for any Distribution Date is less than 7.000% per annum (or, after the Optional Termination Date, 7.500% per annum), the amount of the shortfall which would occur with respect to the assumed certificate for such Distribution Date will be allocated between the Class A-1 Certificates and Class A-2 Certificates in proportion to their current entitlements to interest for such Distribution Date calculated without regard to this cap, and the Net Rate Cap for each such Class for such Distribution Date will be equal to the Pass-Through Rate for such Class for such Distribution Date (determined without regard to the related Net Rate Cap) reduced by the shortfall for such Distribution Date allocable to such Class as determined pursuant to this sentence. For the avoidance of doubt, the Net Rate Cap will not be applicable to the Class A-1 Certificates or Class A-2 Certificates for any Distribution Date on which the weighted average of the Net Mortgage Rates on the Mortgage Loans is equal to or greater than 7.000% per annum (or, after the Optional Termination Date, 7.500% per annum).

If such rate does not appear on such page (or such other page as may replace that page on that service, or if such service is no longer offered, such other service for displaying One-Month LIBOR or comparable rates as may be reasonably selected by the Securities Administrator), One-Month LIBOR for the applicable Interest Accrual Period will be the Reference Bank Rate. If no such quotations can be obtained by the Securities Administrator and no Reference Bank Rate is available, One-Month LIBOR shall be One-Month LIBOR applicable to the preceding Interest Accrual Period. The establishment of One-Month LIBOR on each Interest Determination Date by the Securities Administrator and the Securities Administrator’s calculation of the rate of interest applicable to the LIBOR Certificates for the related Interest Accrual Period shall, in the absence of manifest error, be final and binding. One-Month LIBOR for the Class M Certificates and Class B Certificates and any Accrual Period shall be calculated as described above.

(c)    In the event that a Mortgage Loan is purchased by the Seller or Servicer, as applicable, in accordance with subsections 2.02(a) or (b) above, Section 2.03, the Servicing Agreement or the Mortgage Loan Purchase Agreement, the Seller or Servicer, as applicable, shall remit the applicable Repurchase Price to the Securities Administrator, for deposit in the Distribution Account and shall provide written notice to the Trustee detailing the components of the Repurchase Price, signed by a Servicing Officer or an officer of the Seller, as applicable. Upon deposit of the Repurchase Price in the Distribution Account and upon receipt of a Request for Release with respect to such Mortgage Loan, the Trustee or the Custodian will release to the Seller, the Servicer or the Master Servicer, as applicable, the related Mortgage File and the Trustee shall execute and deliver all instruments of transfer or assignment, without recourse, representation or warranty furnished to it by the Seller, the Servicer or the Master Servicer, as applicable, as are necessary to vest in the Seller, the Servicer or the Master Servicer, as applicable, title to and rights under the Mortgage Loan. Such purchase shall be deemed to have occurred on the date on which the deposit into the Distribution Account was made. The Trustee shall promptly notify the Rating Agencies of such repurchase. The obligation of the Servicer to cure or repurchase for any Mortgage Loan as to which a defect in a constituent document exists shall be the sole remedies respecting such defect available to the Certificateholders or to the Trustee on their behalf. The obligation of the Seller to cure, repurchase or substitute for any Mortgage Loan as to which a defect in a constituent document exists shall be the sole remedies respecting such defect available to the Certificateholders or to the Trustee on their behalf.

Section 2.03    Representations, Warranties and Covenants of the Master Servicer. 

(a)    Wells Fargo Bank, National Association, in its capacity as Master Servicer and Securities Administrator hereby represents and warrants to the Depositor and the Trustee as follows, as of the Closing Date:

(i)    It is a national banking association duly formed, validly existing and in good standing under the laws of the United States of America and is duly authorized and qualified to transact any and all business contemplated by this Agreement to be conducted by the Master Servicer and the Securities Administrator in any state in which a Mortgaged Property is located or is otherwise not required under applicable law to effect such qualification and, in any event, is in compliance with the doing business laws of any such state, to the extent necessary to ensure its ability to enforce each Mortgage Loan, to master service the Mortgage Loans in accordance with the terms of this Agreement and to perform any of its other obligations under this Agreement in accordance with the terms hereof or thereof.

(ii)    It has the full corporate power and authority to execute, deliver and perform, and to enter into and consummate the transactions contemplated by this Agreement and has duly authorized by all necessary corporate action on its part the execution, delivery and performance of this Agreement; and this, assuming the due authorization, execution and delivery hereof by the other parties hereto, constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, except that (a) the enforceability hereof may be limited by bankruptcy, insolvency, moratorium, receivership and other similar laws relating to creditors’ rights generally and (b) the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought.

(iii)    The execution and delivery of this Agreement by it, the consummation of any other of the transactions contemplated by this Agreement, and the fulfillment of or compliance with the terms hereof are in its ordinary course of business and will not (A) result in a material breach of any term or provision of its charter or by-laws or (B) materially conflict with, result in a material breach, violation or acceleration of, or result in a material default under, the terms of any other material agreement or instrument to which it is a party or by which it may be bound, or (C) constitute a material violation of any statute, order or regulation applicable to it of any court, regulatory body, administrative agency or governmental body having jurisdiction over it; and it is not in breach or violation of any material indenture or other material agreement or instrument, or in violation of any statute, order or regulation of any court, regulatory body, administrative agency or governmental body having jurisdiction over it which breach or violation may materially impair its ability to perform or meet any of its obligations under this Agreement.

(iv)    No litigation is pending or, to the best of its knowledge, threatened, against it that would materially and adversely affect the execution, delivery or enforceability of this Agreement or its ability to perform any of its other obligations under this Agreement in accordance with the terms hereof.

(v)    No consent, approval, authorization or order of any court or governmental agency or body is required for its execution, delivery and performance of, or compliance with, this Agreement or the consummation of the transactions contemplated hereby or thereby, or if any such consent, approval, authorization or order is required, it has obtained the same.

(b)    Upon discovery by any of the parties hereto of a breach of a representation or warranty set forth in the Mortgage Loan Purchase Agreement or the Servicing Agreement that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt written notice thereof to the other parties of this Agreement. In accordance with the Servicing Agreement, within 60 days of the discovery of a breach of any representation or warranty set forth in the Servicing Agreement that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the Servicer shall cure such breach in all material respects and, if such breach is not so cured, repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Repurchase Price in the manner set forth below. In accordance with the Mortgage Loan Purchase Agreement, within 60 days of the discovery of a breach of any representation or warranty set forth in the Mortgage Loan Purchase Agreement that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the Seller shall cure such breach in all material respects and, if such breach is not so cured, (i) if such 60-day period expires prior to the second anniversary of the Closing Date, remove such Deleted Mortgage Loan from the Trust Fund and substitute in its place a Replacement Mortgage Loan, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Repurchase Price in the manner set forth below. Notwithstanding the foregoing, if the Servicer fails to cure a breach or repurchase such Mortgage Loan as required by this Section 2.03(b), the Trustee shall then request that the Seller, within 10 days of receipt of a written request from the Trustee, cure such breach or repurchase such Mortgage Loan (or substitute in its place a Replacement Mortgage Loan). Notwithstanding anything to the contrary herein, any such substitution or repurchase of Mortgage Loans pursuant to the foregoing shall not be effected prior to the delivery to the Trustee, the Securities Administrator of an Opinion of Counsel if required by Section 2.05 hereof and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery to the Custodian of a Request for Release.

The Seller or the Servicer, as applicable, shall furnish to the Securities Administrator and the Trustee the Officer’s Certificate required under Section 2.03(b) relating to such cure. If the Trustee has received (or has given, as the case may be) written notice of such a breach of a representation or warranty, the Trustee shall give prompt written notice to the Master Servicer, the Securities Administrator, the Servicer and the Seller, if within 90 days of its receipt (or giving, as the case may be) of such notice of breach, the Trustee does not receive an Officer’s Certificate as described in the preceding sentence certifying as to the cure of such breached representation or warranty. The Seller or Servicer, as applicable, shall promptly reimburse the Trustee for any expenses reasonably incurred by the Trustee in respect of enforcing the remedies for such breach. To enable the Master Servicer to amend the Mortgage Loan Schedule, the Seller or the Servicer, as applicable, shall, unless it cures such breach in a timely fashion pursuant to this Section 2.03, promptly notify the Trustee whether it intends either to repurchase, or in the case of the Seller, to substitute for the Mortgage Loan affected by such breach.

With respect to any Replacement Mortgage Loan or Loans, the Seller shall deliver to the Trustee for the benefit of the Certificateholders such documents and agreements as are required by Section 2.01. No substitution shall be made in any calendar month after the Determination Date for such month. Scheduled Payments due with respect to Replacement Mortgage Loans in the Due Period related to the Distribution Date on which such proceeds are to be distributed shall not be part of the Trust Fund and shall be retained by the Seller. For the month of substitution, distributions to Certificateholders will include the Scheduled Payment due on any Deleted Mortgage Loan for the related Due Period and thereafter the Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Master Servicer shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Replacement Mortgage Loan or Loans and Master Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee, the Seller, the Servicer, the Securities Administrator and the Custodian. Upon such substitution, the Replacement Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the Seller shall be deemed to have made with respect to such Replacement Mortgage Loan or Loans, as of the date of substitution, the representations and warranties set forth in the Mortgage Loan Purchase Agreement or the Servicing Agreement, as applicable, with respect to such Mortgage Loan. Upon any such substitution and the deposit into the Distribution Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph and receipt by the Securities Administrator and the Trustee of a Request for Release for such Mortgage Loan, the Trustee or the Custodian shall release to the Seller the Mortgage File relating to such Deleted Mortgage Loan and held for the benefit of the Certificateholders and the Trustee shall execute and deliver at the Seller’s direction such instruments of transfer or assignment as have been prepared by the Seller without recourse, representation or warranty as shall be necessary to vest in the Seller or its respective designee, title to the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

For any month in which the Seller substitutes one or more Replacement Mortgage Loans for a Deleted Mortgage Loan, the Master Servicer will determine the amount (if any) by which the aggregate principal balance of all the Replacement Mortgage Loans as of the date of substitution is less than the Stated Principal Balance (after application of the principal portion of the Scheduled Payment due in the month of substitution) of such Deleted Mortgage Loan. An amount equal to the aggregate of such deficiencies, described in the preceding sentence for any Distribution Date (such amount, the “Substitution Adjustment Amount”) shall be deposited into the Distribution Account by the Securities Administrator upon receipt from the Seller delivering such Replacement Mortgage Loan on the Determination Date for the Distribution Date relating to the Prepayment Period during which the related Mortgage Loan became required to be purchased or replaced hereunder.

In the event that the Seller or Servicer, as applicable, shall have repurchased a Mortgage Loan, the Repurchase Price therefor shall be deposited into the Distribution Account maintained by the Securities Administrator, on the Determination Date for the Distribution Date in the month following the month during which the Seller or Servicer, as applicable, became obligated to repurchase or, with respect to the Seller, replace such Mortgage Loan and upon such deposit of the Repurchase Price, the delivery of an Opinion of Counsel if required by Section 2.05 and the receipt of a Request for Release, the Trustee or the Custodian shall release the related Mortgage File held for the benefit of the Certificateholders to the Seller or Servicer, as applicable, and the Trustee shall execute and deliver at such Person’s direction the related instruments of transfer or assignment prepared by the Seller or Servicer, as applicable, in each case without recourse, representation or warranty as shall be necessary to transfer title from the Trustee for the benefit of the Certificateholders and transfer the Trustee’s interest to the Seller or Servicer, as applicable to any Mortgage Loan purchased pursuant to this Section 2.03.

In connection with any repurchase or substitution of a Mortgage Loan or the cure of a breach of a representation or warranty set forth in the Mortgage Loan Purchase Agreement or the Servicing Agreement, pursuant to the Mortgage Loan Purchase Agreement, the Seller shall, or shall cause the Servicer to, promptly furnish to the Securities Administrator and the Trustee an Officer’s Certificate, signed by a duly authorized officer of the Seller or the Servicer, as the case may be, to the effect that such repurchase, substitution or cure has been made in accordance with the terms and conditions of this Agreement (or the Servicing Agreement, as applicable) and that all conditions precedent to such repurchase, substitution or cure have been satisfied, including the delivery to the Securities Administrator of the Repurchase Price or Substitution Adjustment Amount, as applicable, for deposit into the Distribution Account, together with copies of any Opinion of Counsel required to be delivered pursuant to this Agreement and the related Request for Release, on which the Securities Administrator and the Trustee may rely. Solely for purposes of the Securities Administrator providing an Assessment of Compliance, upon receipt of such documentation, the Securities Administrator shall approve such repurchase, substitution or cure, as applicable, and which approval shall consist solely of the Securities Administrator’s receipt of such documentation and deposits. It is understood and agreed that the obligation under the Mortgage Loan Purchase Agreement or the Servicing Agreement of the Seller or Servicer, as applicable, to cure the breach of a representation or warranty set forth in the Mortgage Loan Purchase Agreement or the Servicing Agreement, as applicable, or to repurchase or, with respect to the Seller, replace any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedies against the Seller or Servicer, as applicable, respecting such breach available to Certificateholders, the Depositor or the Trustee.

(c)    The representations and warranties set forth in Section 2.03 hereof shall survive delivery of the respective Mortgage Loans and Mortgage Files to the Trustee or the Custodian for the benefit of the Certificateholders.

Section 2.04    Representations and Warranties of the Depositor. 

The Depositor hereby represents and warrants to the Master Servicer, the Securities Administrator and the Trustee as follows, as of the date hereof and as of the Closing Date:

(iii)    The execution and delivery of this Agreement by the Depositor, the consummation of the transactions contemplated by this Agreement, and the fulfillment of or compliance with the terms hereof are in the ordinary course of business of the Depositor and will not (A) result in a breach of any term or provision of the organizational documents of the Depositor or (B) conflict with, result in a breach, violation or acceleration of, or result in a default under, the terms of any other material agreement or instrument to which the Depositor is a party or by which it may be bound or (C) constitute a violation of any statute, order or regulation applicable to the Depositor of any court, regulatory body, administrative agency or governmental body having jurisdiction over the Depositor; and the Depositor is not in breach or violation of any material indenture or other material agreement or instrument, or in violation of any statute, order or regulation of any court, regulatory body, administrative agency or governmental body having jurisdiction over it which breach or violation may materially impair the Depositor’s ability to perform or meet any of its obligations under this Agreement.

(iv)    No litigation is pending, or, to the best of the Depositor’s knowledge, threatened, against the Depositor that would materially and adversely affect the execution, delivery or enforceability of this Agreement or the ability of the Depositor to perform its obligations under this Agreement in accordance with the terms hereof.

The Depositor hereby represents and warrants to the Trustee as of the Closing Date, following the transfer of the Mortgage Loans to it by the Seller pursuant to the Mortgage Loan Purchase Agreement, the Depositor had good title to the Mortgage Loans and the related Mortgage Notes were subject to no offsets, claims, defenses or counterclaims.

It is understood and agreed that the representations and warranties set forth in the immediately preceding paragraph shall survive delivery of the Mortgage Files to the Trustee or the Custodian for the benefit of the Certificateholders. Upon discovery by the Depositor or the Trustee of a breach of such representations and warranties, the party discovering such breach shall give prompt written notice to the others and to each Rating Agency.

Section 2.05    Delivery of Opinion of Counsel in Connection with Substitutions and Repurchases. 

(a)    Notwithstanding any contrary provision of this Agreement, with respect to any Mortgage Loan that is not in default or as to which default is not reasonably foreseeable, no repurchase or substitution pursuant to Sections 2.02 or 2.03 shall be made unless the Seller or the Servicer, as applicable, delivers to the Trustee and the Securities Administrator an Opinion of Counsel, addressed to the Trustee and the Securities Administrator, to the effect that such repurchase or substitution would not (i) result in the imposition of the tax on “prohibited transactions” of REMIC I, REMIC II, REMIC III, or REMIC IV or contributions after the Closing Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively, or (ii) cause any of REMIC I, REMIC II, REMIC III or REMIC IV to fail to qualify as a REMIC at any time that any Certificates are outstanding.

(b)    Upon discovery by the Depositor, the Custodian or the Master Servicer 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 promptly (and in any event within five Business Days of discovery) give written notice thereof to the other parties, the Trustee and the Securities Administrator. In connection therewith, the Trustee, or the Custodian on its behalf, shall require the Seller, at the Seller’s option, to either (i) substitute, if the conditions in Section 2.03(b) with respect to substitutions are satisfied, a Replacement Mortgage Loan for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 60 days of such discovery in the same manner as it would a Mortgage Loan for a breach of representation or warranty contained in Section 2.03. In connection therewith, the Trustee, or the Custodian on its behalf, shall require the Servicer to repurchase the affected Mortgage Loan within 60 days of such discovery in the same manner as it would a Mortgage Loan for a breach of representation or warranty contained in Section 2.03. The Trustee, or the Custodian on its behalf, shall reconvey to the Seller or Servicer, as applicable, the Mortgage Loan to be released pursuant hereto (and the Custodian shall deliver the related Mortgage File) 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 contained in Section 2.03.

Furthermore, the Master Servicer shall oversee and consult with the 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 the Servicer and shall cause the Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by such Person under this Agreement and the Servicing Agreement. The Master Servicer shall independently and separately monitor the 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 Servicer’s and Master Servicer’s records, and based on such reconciled and corrected information, the Master Servicer shall provide such information to the Securities Administrator as shall be necessary in order for it to prepare the statements specified in Section 5.06 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 Securities Administrator and the Servicer pursuant to this Agreement and the Servicing Agreement.

In addition to the foregoing, in connection with a modification of any Mortgage Loan by the Servicer, if the Master Servicer is unable to enforce the obligations of the Servicer with respect to such modification, the Master Servicer shall notify the Depositor of such Servicer’s failure to comply with the terms of the Servicing Agreement or this Agreement. If the Servicing Agreement requires the approval of the Master Servicer for a modification to a Mortgage Loan, the Master Servicer shall approve such modification if, based upon its receipt of written notification from the Servicer outlining the terms of such modification and appropriate supporting documentation, the Master Servicer determines that the modification is permitted under the terms of the Servicing Agreement and that any conditions to such modification set forth in the Servicing Agreement have been satisfied. Furthermore, if the Servicing Agreement requires the oversight and monitoring of loss mitigation measures with respect to the related Mortgage Loans, the Master Servicer will monitor any loss mitigation procedure or recovery action related to a defaulted Mortgage Loan (to the extent it receives notice of such from the Servicer) and confirm that such loss mitigation procedure or recovery action is initiated, conducted and concluded in accordance with any timeframes and any other requirements set forth in the Servicing Agreement, and the Master Servicer shall notify the Depositor in any case in which the Master Servicer believes that the Servicer is not complying with such timeframes and/or other requirements.

The Trustee shall furnish the Servicer and the Master Servicer, upon written request from a servicing officer, with any powers of attorney and other documents in form as provided to it necessary or appropriate to enable the Servicer and the Master Servicer to service and administer the related Mortgage Loans and REO Property.

The Trustee or the Custodian on its behalf, or the Servicer shall provide access to the records and documentation in possession of the Trustee or the Custodian on its behalf, or the Servicer 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, the Custodian or the Servicer; provided, however, that, unless otherwise required by law, neither the Trustee, the Custodian nor the Servicer shall be required to provide access to such records and documentation if the provision thereof would violate the legal right to privacy of any Mortgagor.

In particular, the Trustee shall not (except as otherwise expressly permitted by this Agreement) (a) sell or permit the sale of all or any portion of the Mortgage Loans or of any investment of deposits in an Account without receipt of a REMIC Opinion unless such sale is as a result of a repurchase of the Mortgage Loans pursuant to this Agreement; (b) other than with respect to a substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.02 or Section 2.03 of this Agreement, as applicable, accept any contribution to any REMIC after the Startup Day without receipt of a REMIC Opinion or (c) acquire any assets for any REMIC other than any REO Property after the Startup Day without receipt of a REMIC Opinion.

Section 3.03    Monitoring of Servicer. 

(a)    The Master Servicer shall be responsible for reporting to the Trustee and the Seller the non-compliance by the Servicer with its duties under the Servicing Agreement. In the review of the Servicer’s activities, the Master Servicer may rely upon an Officer’s Certificate of the Servicer with regard to such Person’s compliance with the terms of the Servicing Agreement. In the event that the Master Servicer, in its judgment, determines that the Servicer should be terminated in accordance with the Servicing Agreement, or that a notice should be sent pursuant to the 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 Seller and the Trustee 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 Trustee and the Certificateholders, shall enforce the obligations of the Servicer under the Servicing Agreement, and shall, in the event that the Servicer fails to perform its obligations in accordance with the Servicing Agreement, subject to the preceding paragraph, terminate the rights and obligations of such Person thereunder and act as servicer of the related Mortgage Loans or to cause the Trustee to enter into a new Servicing Agreement with a successor servicer selected by the Master Servicer; provided, however, it is understood and acknowledged by the parties hereto that there shall be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to such successor servicer. In either event, such enforcement, including, without limitation, the legal prosecution of claims, termination of the Servicing Agreement and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, subject to its right of reimbursement pursuant to the provisions of the Servicing Agreement, 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 or related to any termination of a Servicer, or the enforcement or prosecution of related claims, rights or remedies or the appointment of a successor servicer or the transfer and assumption of servicing by the Master Servicer with respect to the 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 Person 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 service to service the Mortgage Loans in accordance with the 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, pursuant to Section 4.04.

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

(e)    If the Master Servicer acts as a servicer, it will not assume liability for the representations and warranties of the Servicer, if any, that it replaces.

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 and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, in each case, in accordance with the provisions of this Agreement and the Servicing Agreement, as applicable; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 3.03, shall not authorize the 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 cause REMIC I, REMIC II, REMIC III or REMIC IV to fail to qualify as a REMIC or result in the imposition of a tax upon the Trust Fund (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) 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 cause REMIC I, REMIC II, REMIC III or REMIC IV to fail to qualify as a REMIC or result in the imposition of a tax upon REMIC I, REMIC II, REMIC III or REMIC IV as the case may be. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney empowering the Master Servicer or the Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, 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 the Servicer). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 9.11 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 Trust, be deemed to be the agent of the Trust.

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

To the extent provided in the Servicing Agreement, to the extent Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer shall cause the Servicer to enforce such clauses in accordance with the Servicing Agreement. If applicable law prohibits the enforcement of a due-on-sale clause or such clause is otherwise not enforced in accordance with the Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the original Mortgagor may be released from liability in accordance with this Agreement or the 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 the 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 Servicing Agreement (or if the Servicer does not, the Master Servicer may), promptly furnish to the Custodian, on behalf of the Trustee, two copies of a certification substantially in the form of Exhibit G (or as otherwise provided in the Custodial Agreement) 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 Protected Account maintained by the Servicer pursuant to Article IV or pursuant to the Servicing Agreement have been or will be so deposited) and shall request that the Custodian, on behalf of the Trustee, deliver to the Servicer the related Mortgage File. Upon receipt of such certification and request, the Custodian, on behalf of the Trustee, shall promptly release the related Mortgage File to the Servicer and the Trustee and Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, the 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, representation or warranty) 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 Protected Account.

(b)    From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan and in accordance with this Agreement or the Servicing Agreement, upon written instruction from such Servicer or the Master Servicer, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by the Servicer or the Master Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Custodian, on behalf of the Trustee, shall, upon the request of the the Servicer or the Master Servicer, and delivery to 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 G (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 Custodian on behalf of the Trustee, when the need therefor by such Person 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 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 and Servicer To Be Held for Trustee. 

(a)    The Master Servicer shall transmit and the Servicer (to the extent required by this Agreement or the Servicing Agreement) shall transmit to the Trustee or Custodian such documents and instruments coming into the possession of such Person from time to time as are required by the terms hereof, or in the case of the Servicer, the Servicing Agreement, to be delivered to the Trustee or Custodian. Any funds received by the Master Servicer or by the Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer or by the Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit of the Trustee and the Certificateholders subject to the Securities Administrator’s right to retain or withdraw from the Distribution Account, the Master Servicing Compensation and other amounts provided in this Agreement, and to the right of the Servicer to retain its Servicing Fee and other amounts as provided in the Servicing Agreement. The Master Servicer and the Servicer shall provide access to information and documentation regarding the Mortgage Loans to the Trustee and, regarding the Mortgage Loans and their respective agents and accountants at any time upon reasonable request and during normal business hours, and to Certificateholders that are savings and loan associations, banks or insurance companies, the Office of Thrift Supervision, the FDIC and the supervisory agents and examiners of such Office and Corporation or examiners of any other federal or state banking or insurance regulatory authority if so required by applicable regulations of the Office of Thrift Supervision or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during normal business hours at the offices of the Master Servicer designated by it. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

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

Section 3.09    Standard Hazard Insurance and Flood Insurance Policies. 

(a)    For each Mortgage Loan, the Master Servicer shall enforce any obligation of the Servicer under the Servicing Agreement to maintain or cause to be maintained standard fire and casualty insurance and, where applicable, flood insurance, all in accordance with the provisions of this Agreement or the Servicing Agreement. It is understood and agreed that such insurance shall be with insurers meeting the eligibility requirements set forth in the 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, any amounts collected by the Servicer 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 Servicing Agreement) shall be deposited by the Servicer or the Master Servicer into the Distribution Account, subject to withdrawal pursuant to Section 4.02. Any cost incurred by the Master Servicer or the 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 the Servicer pursuant to Section 4.02.

Section 3.10    Presentment of Claims and Collection of Proceeds. 

The Master Servicer shall (to the extent provided in this Agreement and the Servicing Agreement) cause the Servicer to, prepare and present on behalf of the Trustee 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 the 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 Mortgage Insurance Policies. 

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

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

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) of any Primary Mortgage Insurance Policies, or certificate of insurance if applicable, and any certificates of renewal as to the foregoing as may be issued from time to time as contemplated by this Agreement. Until all amounts distributable in respect of the Certificates have been distributed in full and the Master Servicer otherwise has fulfilled its obligations under this Agreement, the Trustee (or 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 Mortgage 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 the Servicer (to the extent required under the 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 Servicing Agreement.

Section 3.14    Compensation for the Master Servicer. 

The Master Servicer will be entitled to receive the Master Servicing Fee as compensation for its activities under this Agreement; provided, that the aggregate Master Servicing Fee with respect to any Distribution Date shall be reduced by an amount equal to the Compensating Interest payable by the Master Servicer for such Distribution Date pursuant to Section 5.02 hereof. The Master Servicer will also be entitled to all income and gain realized from any investment of funds in the Distribution Account for the performance of its activities hereunder. 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.

Section 3.15    REO Property. 

(a)    In the event the Trust Fund acquires ownership of any REO Property in respect of any related Mortgage Loan, the deed or certificate of sale shall be issued to the Trustee, or to its nominee, on behalf of the related Certificateholders. The Master Servicer shall, to the extent provided in the Servicing Agreement, cause the Servicer to sell any REO Property as expeditiously as possible and in accordance with the provisions of the Servicing Agreement, as applicable. Pursuant to such efforts to sell such REO Property, the Master Servicer shall cause the Servicer to protect and conserve, such REO Property in the manner and to the extent required by the 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 Servicing Agreement, cause the Servicer to deposit all funds collected and received in connection with the operation of any REO Property in the Protected Account.

(c)    The Master Servicer and the Servicer, upon the final disposition of any REO Property, shall be entitled to reimbursement for any related unreimbursed Advances and other unreimbursed advances as well as any unpaid Servicing Fees from Liquidation Proceeds received in connection with the final disposition of such REO Property; provided, that any such unreimbursed Monthly 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 Servicing Agreement, the Liquidation Proceeds from the final disposition of the REO Property, net of any payment to the Master Servicer and the Servicer as provided above shall be deposited in the Protected Account on the next succeeding Business Day following receipt thereof and be remitted by wire transfer in immediately available funds to the Securities Administrator for deposit into the related Distribution Account on the next succeeding Remittance Date.

Section 3.16    Annual Statement as to Compliance. 

The Master Servicer and the Securities Administrator shall deliver (or otherwise make available) to the Depositor and the Securities Administrator not later than March 15 ^th of each calendar year beginning in 2007, an Officer’s Certificate (an “Annual Statement of Compliance”) stating, as to each signatory thereof, that (i) a review of the activities of each such party during the preceding calendar year and of its performance under this Agreement or other applicable servicing agreement has been made under such officer’s supervision and (ii) to the best of such officer’s knowledge, based on such review, such party has fulfilled all of its obligations under this Agreement or other applicable servicing agreement in all material respects throughout such year, or, if there has been a failure to fulfill any such obligation in any material respect, specifying each such failure known to such officer and the nature and status of the cure provisions thereof. Such Annual Statement of Compliance shall contain no restrictions or limitations on its use. The Master Servicer shall enforce the obligations of the Servicer, to the extent set forth in the Servicing Agreement, to deliver a similar Annual Statement of Compliance by the Servicer to the Depositor and the Securities Administrator as described above as and when required with respect to the Master Servicer. In the event that certain servicing responsibilities with respect to any Mortgage Loan have been delegated by the Master Servicer, the Securities Administrator or the Servicer to a subservicer or subcontractor, each such entity shall cause such subservicer or subcontractor (and with respect to the Servicer, the Master Servicer shall enforce the obligation of the Servicer to the extent required under the Servicing Agreement) to deliver a similar Annual Statement of Compliance by such subservicer or subcontractor to the Depositor and the Securities Administrator as described above as and when required with respect to the Master Servicer or the Servicer (as the case may be).

Failure of the Master Servicer to comply with this Section 3.16 (including with respect to the timeframes required herein) shall be deemed an Event of Default, and at the written direction of the Depositor the Trustee shall, in addition to whatever rights the Trustee may have under this Agreement and at law or equity or to damages, including injunctive relief and specific performance, upon notice immediately terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Master Servicer for the same. Failure of the Securities Administrator to comply with this Section 3.16 (including with respect to the timeframes required in this Section) which failure results in a failure to timely file the related Form 10-K, shall be deemed a default and the Trustee at the written direction of the Depositor shall, in addition to whatever rights the Trustee may have under this Agreement and at law or equity or to damages, including injunctive relief and specific performance, upon notice immediately terminate all of the rights and obligations of the Securities Administrator under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Securities Administrator for the same. This paragraph shall supersede any other provision in this Agreement or any other agreement to the contrary.

In the event the Master Servicer, the Securities Administrator or any subservicer or subcontractor engaged by either such party is terminated or resigns pursuant to the terms of this Agreement, or any other applicable agreement in the case of a subservicer or subcontractor, as the case may be, such party shall provide an Annual Statement of Compliance pursuant to this Section 3.16 or to the related section of such other applicable agreement, as the case may be, as to the performance of its obligations with respect to the period of time it was subject to this Agreement or any other applicable agreement, as the case may be notwithstanding any such termination or resignation.

Section 3.17    Assessments of Compliance and Attestation Reports. 

Pursuant to Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122 of Regulation AB, each of the Master Servicer, the Securities Administrator and the Custodian (to the extent set forth in this Section) (each, an “Attesting Party”) shall deliver (or otherwise make available) to the Master Servicer, the Securities Administrator and the Depositor on or before March 15 ^th of each calendar year beginning in 2007, a report regarding such Attesting Party’s assessment of compliance (an “Assessment of Compliance”) with the Servicing Criteria during the preceding calendar year. The Assessment of Compliance, as set forth in Regulation AB, must contain the following:

(a)    A statement by an authorized officer of such Attesting Party of its authority and responsibility for assessing compliance with the Servicing Criteria applicable to the related Attesting Party;

(b)    A statement by an authorized officer that such Attesting Party used the Servicing Criteria attached as Exhibit N hereto, and which will also be attached to the Assessment of Compliance, to assess compliance with the Servicing Criteria applicable to the related Attesting Party;

(c)    An assessment by such officer of the related Attesting Party’s compliance with the applicable Servicing Criteria for the period consisting of the preceding calendar year, including disclosure of any material instance of noncompliance with respect thereto during such period, which assessment shall be based on the activities such Attesting Party performs with respect to asset-backed securities transactions taken as a whole involving the related Attesting Party, that are backed by the same asset type as the Mortgage Loans;

(d)    A statement that a registered public accounting firm has issued an attestation report on the related Attesting Party’s Assessment of Compliance for the period consisting of the preceding calendar year; and

(e)    A statement as to which of the Servicing Criteria, if any, are not applicable to the related Attesting Party, which statement shall be based on the activities such Attesting Party performs with respect to asset-backed securities transactions taken as a whole involving such Attesting Party, that are backed by the same asset type as the Mortgage Loans.

Such report at a minimum shall address each of the Servicing Criteria specified on Exhibit N hereto which are indicated as applicable to the related Attesting Party.

On or before March 15 ^th of each calendar year beginning in 2007, each Attesting Party shall furnish to the Master Servicer, the Depositor and the Securities Administrator a report (an “Attestation Report”) by a registered public accounting firm that attests to, and reports on, the Assessment of Compliance made by the related Attesting Party, as required by Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122(b) of Regulation AB, which Attestation Report must be made in accordance with standards for attestation reports issued or adopted by the Public Company Accounting Oversight Board.

The Master Servicer shall enforce the obligation of the Servicer to deliver to the Securities Administrator, the Master Servicer and the Depositor an Assessment of Compliance and Attestation Report as and when provided in the Servicing Agreement. Each of the Master Servicer and the Securities Administrator shall cause, and the Master Servicer shall enforce the obligation (as and when provided in the Servicing Agreement) of the Servicer to cause, any subservicer and each subcontractor (to the extent such subcontractor is determined by the Master Servicer or the Securities Administrator, as applicable, to be “participating in the servicing function” within the meaning of Item 1122 of Regulation AB) that is engaged by the Servicer, the Master Servicer or the Securities Administrator, as applicable, to deliver to the Securities Administrator, the Master Servicer and the Depositor an Assessment of Compliance and Attestation Report as and when provided above. Such Assessment of Compliance, as to any subservicer or subcontractor, shall at a minimum address the applicable Servicing Criteria specified on Exhibit N hereto which are indicated as applicable to any “primary servicer” to the extent such subservicer or subcontractor is performing any servicing function for the party who engages it and to the extent such party is not itself addressing the Servicing Criteria related to such servicing function in its own Assessment of Compliance. The Securities Administrator shall confirm that each of the Assessments of Compliance delivered to it, taken as a whole, address all of the Servicing Criteria and taken individually address the Servicing Criteria for each party as set forth in Exhibit N and notify the Depositor of any exceptions. Notwithstanding the foregoing, as to any subcontractor, an Assessment of Compliance is not required to be delivered unless it is required as part of a Form 10-K with respect to the Trust Fund.

The Custodian shall deliver to the Master Servicer, the Securities Administrator and the Depositor an Assessment of Compliance and Attestation Report, as and when provided above, which shall at a minimum address each of the Servicing Criteria specified on Exhibit N hereto which are indicated as applicable to a “custodian”. Notwithstanding the foregoing, an Assessment of Compliance or Attestation Report is not required to be delivered by any Custodian unless it is required as part of a Form 10-K with respect to the Trust Fund.

Failure of the Master Servicer to comply with this Section 3.17 (including with respect to the timeframes required herein) shall constitute an Event of Default, and at the written direction of the Depositor the Trustee shall, in addition to whatever rights the Trustee may have under this Agreement and at law or equity or to damages, including injunctive relief and specific performance, upon notice immediately terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Master Servicer for the same (but subject to the Master Servicer’s rights to payment of any Master Servicing Compensation and reimbursement of all amounts for which it is entitled to be reimbursed prior to the date of termination). Failure of the Securities Administrator to comply with this Section 3.17 (including with respect to the timeframes required in this Section) which failure results in a failure to timely file the related Form 10-K, shall constitute a default and at the written direction of the Depositor the Trustee shall, in addition to whatever rights the Trustee may have under this Agreement and at law or equity or to damages, including injunctive relief and specific performance, upon notice immediately terminate all of the rights and obligations of the Securities Administrator under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Securities Administrator for the same (but subject to the Securities Administrator’s right to reimbursement of all amounts for which it is entitled to be reimbursed prior to the date of termination). This paragraph shall supersede any other provision in this Agreement or any other agreement to the contrary.

In the event the Master Servicer, the Custodian, the Securities Administrator, the Servicer, or any subservicer or subcontractor engaged by any such party is terminated, assigns its rights and obligations under, or resigns pursuant to, the terms of this Agreement, the Custodial Agreement, or any other applicable agreement in the case of a subservicer or subcontractor, as the case may be, such party shall provide an Assessment of Compliance with respect to the period of time it was subject to this Agreement or any other applicable agreement and cause to be provided an Attestation Report pursuant to this Section 3.17 or to the related section of such other applicable agreement, as the case may be, notwithstanding any such termination, assignment or resignation.

Section 3.18    Reports Filed with Securities and Exchange Commission. 

(a)    (i) (A) Within 15 days after each Distribution Date, the Securities Administrator shall, in accordance with industry standards, prepare and file with the Commission via the Electronic Data Gathering and Retrieval System (“EDGAR”), a Distribution Report on Form 10-D, signed by the Master Servicer, with a copy of the Monthly Statement to be furnished by the Securities Administrator to the Certificateholders for such Distribution Date; provided that, the Securities Administrator shall have received no later than five (5) calendar days after the related Distribution Date, all information required to be provided to the Securities Administrator as described in clause (a)(iv) below. Any disclosure that is in addition to the Monthly Statement and that is required to be included on Form 10-D (“Additional Form 10-D Disclosure”) shall be, pursuant to the paragraph immediately below, reported by the parties set forth on Exhibit O to the Securities Administrator and the Depositor and approved for inclusion by the Depositor, and the Securities Administrator will have no duty or liability for any failure hereunder to determine or prepare any Additional Form 10-D Disclosure absent such reporting (other than in the case where the Securities Administrator is the reporting party as set forth in Exhibit O) and approval.

(B)    Within five (5) calendar days after the related Distribution Date, (i) the parties set forth in Exhibit O shall be required to provide, and the Master Servicer shall enforce the obligation of the Servicer (to the extent provided in the Servicing Agreement) to provide, pursuant to Section 3.18(a)(iv) below, to the Securities Administrator and the Depositor, to the extent known by a responsible officer thereof, in EDGAR-compatible format, or in such other form as otherwise agreed upon by the Securities Administrator and the Depositor and such party, the form and substance of any Additional Form 10-D Disclosure, if applicable, and (ii) the Depositor will approve, as to form and substance, or disapprove, as the case may be, the inclusion of the Additional Form 10-D Disclosure on Form 10-D. The Depositor shall be responsible for any reasonable fees and expenses assessed or incurred by the Securities Administrator in connection with including any Additional Form 10-D Disclosure on Form 10-D pursuant to this Section.

(C)    After preparing the Form 10-D, the Securities Administrator shall forward electronically a copy of the Form 10-D to the Depositor (in the case of any Additional 10-D Disclosure and otherwise if requested by the Depositor) and the Master Servicer for review. Within two Business Days after receipt of such copy, but no later than the 12th calendar day after the Distribution Date (provided that, the Securities Administrator forwards a copy of the Form 10-D no later than the 10 ^th calendar 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. In the absence of receipt of any written changes or approval, the Securities Administrator shall be entitled to assume that such Form 10-D is in final form and the Securities Administrator may proceed with the execution and filing of the Form 10-D. No later than the 13th calendar day after the related Distribution Date, a duly authorized officer of the Master Servicer shall sign the Form 10-D and, in the case where the Master Servicer and the Securities Administrator are not affiliated, return an electronic or fax copy of such signed Form 10-D (with an original executed hard copy to follow by overnight mail) to the Securities Administrator. 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 shall follow the procedures set forth in Section 3.18(a)(v)(B). Promptly (but no later than one (1) Business Day) after filing with the Commission, the Securities Administrator shall make available on its internet website identified in Section 5.06 a final executed copy of each Form 10-D filed by the Securities Administrator. The signing party at the Master Servicer can be contacted as set forth in Section 11.05. Form 10-D requires the registrant to indicate (by checking “yes” or “no”) that it (1) has filed all reports required to be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter period that the registrant was required to file such reports), and (2) has been subject to such filing requirements for the past 90 days. The Depositor shall notify the Securities Administrator in writing, no later than the fifth calendar day after the related Distribution Date with respect to the filing of a report on Form 10-D if the answer to the questions should be “no”. The Securities Administrator shall be entitled to rely on the representations in Section 2.04(vi) and in any such notice in preparing, executing and/or filing any such report. The parties to this Agreement acknowledge that the performance by the Master Servicer and the Securities Administrator of their respective duties under Sections 3.18(a)(i) and (v) related to the timely preparation, execution and filing of Form 10-D is contingent upon such parties strictly observing all applicable deadlines in the performance of their duties under such Sections. Neither the Master Servicer nor the Securities Administrator shall have any liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare, execute and/or timely file such Form 10-D, where such failure results from a party’s failure to deliver, on a timely basis, any information from such party needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.
