Business Day: Any day other than (i) a Saturday or Sunday or (ii) a day on which banking and savings and loan institutions in the States of New York, Maryland, Minnesota and, with respect to any Trust, the jurisdiction in which the related Trustee conducts its trust business, are authorized or obligated by law or executive order to be closed.

Delinquent: For reporting purposes, a Securitized Loan is “delinquent” when any payment contractually due thereon has not been made by the close of business on the Due Date therefor. Such Securitized Loan is “30 days Delinquent” if such payment has not been received by the close of business on the corresponding day of the month immediately succeeding the month in which such payment was first due, or, if there is not such corresponding day (e.g., as when a 30-day month follows a 31-day month in which a payment was due on the 31st day of such month), then on the last day of such immediately succeeding month.

Due Date: The day of the calendar month on which the Monthly Payment is due on a Securitized Loan, exclusive of any days of grace. With respect to the Securitized Loans for which payment from the Mortgagor is due on a day other than the first day of the calendar month, such Securitized Loans will be treated as if the Monthly Payment is due on the first day of the immediately succeeding month.

(a)

The Seller and the Servicer agree that from time to time the Seller shall effect the sale or transfer of some or all of the Mortgage Loans to a Trust to be formed as part of a Pass-Through Transfer. The Servicer shall cooperate with the Seller in connection with any Pass-Through Transfer contemplated by the Seller pursuant to this Section 2.01, including without limitation providing requested information and reports to, and otherwise cooperating with, any Credit Risk Manager. In connection therewith, the Servicer shall provide to the Seller and any Trustee, Trust, Depositor, underwriter, initial purchaser, Certificate Insurer or Credit Risk Manager in connection with a Pass-Through Transfer, as the case may be: (i) any and all information and appropriate verification of information which may be reasonably available to the Servicer, including the Servicer's foreclosure, delinquency experience and the Servicer's underwriting standards, whether through letters of its auditors and counsel or otherwise, as such parties shall reasonably request; and (ii) such additional representations, warranties, covenants, opinions of counsel, letters from auditors, and certificates of public officials or officers of the Servicer as are reasonably believed necessary by the Seller and any Trustee, Trust, Depositor, underwriter, initial purchaser, Certificate Insurer or Credit Risk Manager, as the case may be, in connection with such Pass-Through Transfer. The Servicer shall indemnify the Depositor for any material misstatements or omissions or alleged material misstatements or omissions contained in the information provided pursuant to this Section 2.01(a). The Seller shall provide the Servicer with a Transfer Notice with respect to any such Pass-Through Transfer, including a schedule of Mortgage Loans which have been transferred, the Effective Date of the Pass-Through Transfer and the name and address of the related Trustee. Upon the Effective Date of such a Pass-Through Transfer, (A) the Servicer and the Seller agree that the provisions of this Agreement shall go into effect with respect to the Securitized Loans to which the Transfer Notice relates, and (B) the Servicer agrees to recognize the Trustee and Trust with respect to the transferred Mortgage Loans in the Pass-Through Transfer, or the Master Servicer acting on their behalf, as having the same rights under this Agreement as the Seller with respect to such transferred Mortgage Loans, including without limitation the right to terminate the Servicer under this Agreement.

Section 2.02

Contract for Servicing; Possession of Servicing Files.

The Seller, by execution and delivery of this Agreement, does hereby contract with the Servicer, subject to the terms of this Agreement, for the servicing of the Securitized Loans. On or before each Closing Date, the Seller shall cause to be delivered to the Servicer the Servicing Files with respect to the Securitized Loans listed in the schedule attached to the applicable Transfer Notice. Each Servicing File delivered to the Servicer shall be held in trust by the Servicer for the benefit of the Trust; provided, however, that the Servicer shall have no liability for any Servicing Files (or portions thereof) not delivered by the Seller. The Servicer’s possession of any portion of the Securitized Loan documents shall be on behalf of the Trust for the sole purpose of facilitating servicing of the related Securitized Loan pursuant to this Agreement, and such retention and possession by the Servicer shall be in a custodial capacity only. The ownership of each Mortgage Note, Mortgage, and the contents of the Servicing File shall be vested in the Trust and the ownership of all records and documents with respect to the related Securitized Loan prepared by or which come into the possession of the Servicer shall immediately vest in the Trust and shall be retained and maintained, in trust, by the Servicer on behalf of the Trust in such custodial capacity only. The portion of each Servicing File retained by the Servicer pursuant to this Agreement shall be segregated from the other books and records of the Servicer and shall be appropriately marked to clearly reflect the ownership of the related Securitized Loan by the Trust. The Servicer shall release from its custody the contents of any Servicing File retained by it only in accordance with this Agreement.

Section 2.03

(a)

As soon as practicable after the Closing Date or the date on which a Qualifying Substitute Mortgage Loan is delivered pursuant to a Trust Agreement, as applicable (but in no event more than 90 days thereafter except to the extent delays are caused by the applicable recording office), the Seller shall cause the Mortgage or Assignment of Mortgage, as applicable, with respect to each related MERS Eligible Securitized Loan, to be properly recorded in the name of MERS in the public recording office in the applicable jurisdiction, or shall ascertain that such have previously been so recorded.

(b)

An Assignment of Mortgage in favor of the Trustee on behalf of the Trust shall be recorded as to each Non-MERS Securitized Loan, unless instructions to the contrary are delivered to the Seller, in writing, by the Trustee, or the Seller obtains an Opinion of Counsel that recordation of such Assignment of Mortgage is not required. Subject to the preceding sentence, as soon as practicable after the Closing Date (but in no event more than 90 days thereafter except to the extent delays are caused by the applicable recording office), the Seller shall cause such related Assignment of Mortgage to be properly recorded in each public recording office where such Non-MERS Eligible Securitized Loans are recorded, unless the Seller obtains an Opinion of Counsel that recordation of such an Assignment of Mortgage is not required.

(c)

All rights arising out of the Securitized Loans shall be vested in the related Trust, subject to the Servicer’s right to service and administer the Securitized Loans hereunder in accordance with the terms of this Agreement. All funds received on or in connection with a Securitized Loan, other than the Servicing Fee and other compensation to which the Servicer is entitled as set forth herein, including but not limited to that compensation as set forth in Section 5.01 below, shall be received and held by the Servicer in trust for the benefit of the related Trust pursuant to the terms of this Agreement.

ARTICLE III.

SERVICING OF THE SECURITIZED LOANS

Section 3.01

Servicer to Service.

The Servicer, as an independent contractor, shall service and administer the Securitized Loans from and after the Closing Date and shall have full power and authority, acting alone, to do any and all things in connection with such servicing and administration which the Servicer may deem necessary or desirable, consistent with the terms of this Agreement and with Accepted Servicing Practices. The Servicer may designate a Subservicer to perform the obligations and exercise the discretion of the Servicer pursuant to this Agreement, provided that such designation shall not relieve the Servicer of such obligations.

The Seller and the Servicer additionally agree as follows:

(a)

[reserved]

(b)

If applicable, the Servicer shall, in accordance with the relevant provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇▇▇▇ National Affordable Housing Act of 1990, as the same may be amended from time to time, and the regulations provided in accordance with the Real Estate Settlement Procedures Act, provide notice to the Mortgagor of each Securitized Loan of the transfer of the servicing thereto to the Servicer.

(c)

The Servicer shall be responsible for the preparation of and costs associated with notifications to Mortgagors of the assumption of servicing by the Servicer.

Consistent with the terms of this Agreement and except as provided in Section 3.15 hereof, the Servicer may waive any late payment charge, assumption fee or other fee (other than a Prepayment Charge) that may be collected in the ordinary course of servicing the Securitized Loans. The Servicer shall not make any future advances to any Mortgagor under any Securitized Loan, and (unless the Mortgagor is in default with respect to the Securitized Loan or such default is, in the judgment of the Servicer, reasonably foreseeable) the Servicer shall not permit any modification of any material term of any Securitized Loan, including any modification that would change the Mortgage Interest Rate, defer or forgive the payment of principal or interest, reduce or increase the outstanding principal balance (except for actual payments of principal) or change the final maturity date on such Securitized Loan. The Certificate Insurer’s prior written consent shall be required for any modification, waiver or amendment if the aggregate number of outstanding Securitized Loans which have been modified, waived or amended exceeds 5% of the number of Securitized Loans in the related Trust as of the Effective Date. In the event of any such modification which permits the deferral of interest or principal payments on any Securitized Loan, the Servicer shall, on the Business Day immediately preceding the Remittance Date in any month in which any such principal or interest payment has been deferred, make a Monthly Advance in accordance with Section 4.03, in an amount equal to the difference between (a) such month’s principal and one month’s interest at the Securitized Loan Remittance Rate on the unpaid principal balance of such Securitized Loan and (b) the amount paid by the Mortgagor. The Servicer shall be entitled to reimbursement for such advances to the same extent as for all other advances made pursuant to Section 4.03. The Servicer may permit modifications to a Securitized Loan, with the consent of the Certificate Insurer, which are authorized by the express terms of either an allonge to the related Mortgage Note or an addendum to the related Mortgage in existence as of the Effective Date. Without limiting the generality of the foregoing, the Servicer shall continue, and is hereby authorized and empowered, to execute and deliver on behalf of itself and the related Trust, all instruments of satisfaction or cancellation, or of partial or full release, discharge and all other comparable instruments, with respect to the Securitized Loans and with respect to the Mortgaged Properties. Upon the written request of the Servicer, the Trustee shall execute and deliver to the Servicer, within the later of fifteen days from the Closing Date or within fifteen days of such Servicer request, any powers of attorney (one for each county in which any of the Mortgaged Properties are located) and other documents, furnished to it by the Servicer and reasonably satisfactory to the Trustee, necessary or appropriate to enable the Servicer to carry out its servicing and administrative duties under this Agreement.

Notwithstanding anything in this Agreement to the contrary, the Servicer (a) shall not permit any modification with respect to any Securitized Loan that would change the Mortgage Interest Rate and (b) shall not (unless the Mortgagor is in default with respect to the Securitized Loan or such default is, in the judgment of the Servicer, reasonably foreseeable) make or permit any modification, waiver or amendment of any term of any Securitized Loan that would both (i) effect an exchange or reissuance of such Securitized Loan under Section 1001 of the Code (or Treasury regulations promulgated thereunder) and (ii) cause the Trust Fund to fail to qualify as a REMIC under the Code or the imposition of any tax on "prohibited transactions" or "contributions" after the startup date under the REMIC Provisions.

Prior to taking any action with respect to the Securitized Loans which is not contemplated under the terms of this Agreement, the Servicer will obtain an Opinion of Counsel acceptable to the Certificate Insurer and the Trustee or the Master Servicer on its behalf with respect to whether such action could result in the imposition of a tax upon the REMIC (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) (either such event, an "Adverse REMIC Event"), and the Servicer shall not take any such action or cause the Trust Fund to take any such action as to which it has been advised that an Adverse REMIC Event could occur.

The Servicer shall not permit the creation of any "interests" (within the meaning of Section 860G of the Code) in the REMIC. The Servicer shall not enter into any arrangement by which the REMIC will receive a fee or other compensation for services nor permit the REMIC to receive any income from assets other than "qualified mortgages" as defined in Section 860G(a)(3) of the Code or "permitted investments" as defined in Section 860G(a)(5) of the Code.

Section 3.02

Collection of Securitized Loan Payments.

Continuously from the Closing Date until the date each Securitized Loan ceases to be subject to this Agreement, the Servicer shall proceed diligently to collect all payments due under each of the Securitized Loans when the same shall become due and payable and shall take special care in ascertaining and estimating Escrow Payments and all other charges that will become due and payable with respect to the Securitized Loans and each related Mortgaged Property, to the end that the installments payable by the Mortgagors will be sufficient to pay such charges as and when they become due and payable.

Section 3.03

Establishment of and Deposits to Custodial Account.

(a)

The Servicer shall segregate and hold all funds collected and received pursuant to the Securitized Loans separate and apart from any of its own funds and general assets and shall establish and maintain for each related Trust a Custodial Account, in the form of a time deposit or demand account, titled “[Cenlar FSB], as Servicer for ▇▇▇▇▇ Fargo Bank, National Association, as Master Servicer, and in trust for [Name of Trust].” The Custodial Account shall be established with a Qualified Depository. Any funds deposited in the Custodial Account may be invested in Eligible Investments subject to the provisions of Section 3.11 hereof. Funds deposited in the Custodial Account may be drawn on by the Servicer in accordance with Section 3.04 hereof. The creation of the Custodial Account shall be evidenced by a letter agreement in the form of Exhibit B. A copy of such letter agreement shall be furnished to each Trustee, each Certificate Insurer and the Master Servicer. The Certificate Insurer, the Trustee and the Master Servicer shall also be notified of any change in the location of the Custodial Account.

(b)

The Servicer shall deposit in the Custodial Account on a daily basis, and retain therein, the following collections received by the Servicer and payments made by the Servicer after the Closing Date:

(xiii)

any amounts received by it under any PMI Policy; and

(xiv)

any other amount required hereunder to be deposited by the Servicer in the Custodial Account.

Notwithstanding the foregoing clause (viii), no Monthly Advances or Servicing Advances shall be required to be made by the Servicer if such Monthly Advance or Servicing Advance would, if made, be, in the Servicer’s reasonable judgment in accordance with Accepted Servicing Practices, nonrecoverable. The determination by the Servicer that it has made a nonrecoverable Monthly Advance or Servicing Advance, or that any proposed Monthly Advance or Servicing Advance would be a nonrecoverable advance, shall be evidenced by an Officer’s Certificate of the Servicer delivered to the Master Servicer and the Certificate Insurer.

The foregoing requirements for deposit into the Custodial Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of (i) late payment charges, penalty interest and insufficient fund charges, (ii) assumption and modification fees, (iii) other Ancillary Income and (iv) the Servicing Fee need not be deposited by the Servicer into the Custodial Account.

Any interest paid on funds deposited in the Custodial Account by the depository institution shall accrue to the benefit of the Servicer as additional servicing compensation and the Servicer shall be entitled to retain and withdraw such interest from the Custodial Account pursuant to Section 3.04 of this Agreement. Additionally, any other benefit derived from the Custodial Account associated with the receipt, disbursement and accumulation of principal, interest, taxes, hazard insurance, mortgage insurance, etc. shall accrue for the benefit of the Servicer.

The Servicer may recover at any time from amounts on deposit in the Custodial Account with respect to Securitized Loans in the same Trust the amount of any Monthly Advances that the Servicer deems nonrecoverable or that remain unreimbursed to the Servicer from related Liquidation Proceeds after the final liquidation of the related Securitized Loan. In addition, the Servicer may, at any time, withdraw from the Custodial Account funds that are held for future distribution (i.e., were not included in the principal and interest for the preceding Remittance Date) to reimburse itself for Monthly Advances previously made by the Servicer;

(vii)

to reimburse itself for unreimbursed Servicing Advances, and for any unpaid Servicing Fees, the Servicer’s right to reimburse itself pursuant to this subclause (vii) with respect to any Securitized Loan being limited to related Liquidation Proceeds, Condemnation Proceeds, Insurance Proceeds, REO Disposition Proceeds and other amounts received in respect of the related REO Property, and such other amounts as may be collected by the Servicer from the Mortgagor or otherwise relating to the Securitized Loan, it being understood that, in the case of any such reimbursement, the Servicer’s right thereto shall be prior to the rights of the related Trust;

The Servicer shall segregate and hold all funds collected and received pursuant to a Securitized Loan constituting Escrow Payments separate and apart from any of its own funds and general assets and shall establish and maintain an Escrow Account, in the form of a time deposit or demand account, titled “[Cenlar FSB], as Servicer for ▇▇▇▇▇ Fargo Bank, National Association, as Master Servicer, and in trust for one or more UBS Mortgage Securities Trusts.” The Escrow Account shall be established with a Qualified Depository in a manner that shall provide maximum available insurance thereunder. Funds deposited in the Escrow Account may be drawn on by the Servicer in accordance with Section 3.06. The creation of the Escrow Account shall be evidenced by a letter agreement in the form of Exhibit C. A copy of such certification or letter agreement shall be furnished to each Trustee and the Master Servicer.

(vii)

to withdraw any funds deposited into the Escrow Account in error; and

(viii)

to clear and terminate the Escrow Account on the termination of this Agreement.

The Servicer will be responsible for the administration of the Escrow Accounts and will be obligated to make Servicing Advances to the Escrow Account in respect of its obligations under this Section 3.06, reimbursable from the Escrow Accounts or Custodial Account to the extent not collected from a Mortgagor, anything to the contrary notwithstanding, when and as necessary to avoid the lapse of insurance coverage on the related Mortgaged Property, or which the Servicer knows, or in the exercise of the required standard of care of the Servicer hereunder should know, is necessary to avoid the loss of such Mortgaged Property due to a tax sale or the foreclosure as a result of a tax lien. If any such payment has not been made and the Servicer receives notice of a tax lien with respect to such Mortgaged Property being imposed, the Servicer will, within ten (10) Business Days of such notice, advance or cause to be advanced funds necessary to discharge such lien on such Mortgaged Property.

Section 3.07

Fidelity Bond and Errors and Omissions Insurance.

The Servicer shall keep in force during the term of this Agreement a Fidelity Bond and Errors and Omissions Insurance the minimum coverage of which shall be at least equal to the coverage required by the Master Servicer in the Master Servicing Guide (unless a waiver of such requirement has been obtained by the Servicer from the Master Servicer and Certificate Insurer). Such Fidelity Bond and Errors and Omissions Insurance shall be maintained with recognized insurers, shall be in such form and amount as would permit Servicer to be qualified with the Master Servicer as a servicer, and shall by its terms not be cancelable without thirty days’ prior written notice to the Trustee, the Certificate Insurer and the Master Servicer. The Servicer shall be deemed to have complied with this provision if an affiliate of the Servicer has such errors and omissions and fidelity bond coverage and, by the terms of such insurance policy or fidelity bond, the coverage afforded thereunder extends to the Servicer. The Servicer shall furnish to the Trustee, each Certificate Insurer (upon reasonable request) and the Master Servicer a copy of each such bond and insurance policy upon their request.

Section 3.09

Notification of Adjustments.

With respect to each Adjustable Rate Securitized Loan, the Servicer shall adjust the Mortgage Interest Rate on the related interest rate adjustment date and shall adjust the Monthly Payment on the related mortgage payment adjustment date, if applicable, in compliance with the requirements of applicable law and the related Mortgage and Mortgage Note. The Servicer shall execute and deliver any and all necessary notices required under applicable law and the terms of the related Mortgage Note and Mortgage regarding the Mortgage Interest Rate and Monthly Payment adjustments. The Servicer shall promptly, upon written request therefor, deliver to the Master Servicer such notifications and any additional applicable data regarding such adjustments and the methods used to calculate and implement such adjustments. Upon the discovery by the Servicer or the receipt of notice from the Master Servicer that the Servicer has failed to adjust a Mortgage Interest Rate or Monthly Payment in accordance with the terms of the related Mortgage Note, the Servicer shall immediately deposit in the Custodial Account from its own funds the amount of any interest loss or deferral caused thereby and shall indemnify the Trust in respect of any liability as a result of such shortfall.

Section 3.10

Payment of Taxes, Insurance and Other Charges.

With respect to each Securitized Loan, the Servicer shall maintain accurate records reflecting the status of ground rents, taxes, assessments, water rates and other charges which are or may become a lien upon the Mortgaged Property and the status of fire and hazard insurance coverage and shall obtain, from time to time, all bills for the payment of such charges (including renewal premiums) and shall effect payment thereof prior to the applicable penalty or termination date and at a time appropriate for securing maximum discounts allowable, employing for such purpose deposits of the Mortgagor in the Escrow Account which shall have been estimated and accumulated by the Servicer in amounts sufficient for such purposes, as allowed under the terms of the Mortgage or applicable regulations. The Servicer assumes full responsibility for the payment of all such bills and shall effect payments of all such bills irrespective of the Mortgagor’s faithful performance in the payment of same or the making of the Escrow Payments and shall make advances from its own funds to effect such payments; provided, however, with respect to Securitized Loans for which Escrow Payments are not required to be paid by the related Mortgagor, the Servicer shall not be responsible to effect the related payments until receipt of notice that such payments are past due. The Servicer shall employ Accepted Servicing Practices to ensure that the related Mortgaged Property is not subjected to a tax lien as a result of nonpayment and that such Mortgaged Property is not left uninsured.

Section 3.11

Protection of Accounts.

The Servicer may transfer the Custodial Account or the Escrow Account to a different Qualified Depository from time to time. The Servicer shall give written notice to the Trustee and the Certificate Insurer and the Master Servicer of the location of the Custodial Account and the Escrow Account maintained by it with respect to the Securitized Loans when established and prior to any change thereof.

The Servicer shall bear any expenses, losses or damages sustained by the Trustee or the Master Servicer if the Custodial Account and/or the Escrow Account are not demand deposit accounts.

Amounts on deposit in the Custodial Account and the Escrow Account may at the option of the Servicer be invested in Eligible Investments; provided that in the event that amounts on deposit in the Custodial Account or the Escrow Account exceed the amount fully insured by the FDIC (the “Insured Amount”), the Servicer shall be obligated to invest the excess amount over the Insured Amount in Eligible Investments on the same Business Day as such excess amount becomes present in the Custodial Account or the Escrow Account. Any such Eligible Investment shall mature no later than the Business Day immediately preceding the related Remittance Date or other date on which funds are needed to be disbursed. Any such Eligible Investment shall be made in the name of the Servicer in trust for the benefit of one or more UBS Mortgage Securities Trusts, as their interests may appear. All income on or gain realized from any such Eligible Investment shall be for the benefit of the Servicer and may be withdrawn at any time by the Servicer. Any losses incurred in respect of any such investment shall be deposited in the Custodial Account or the Escrow Account by the Servicer out of its own funds immediately as realized.

Section 3.12

Title, Management and Disposition of REO Property.

In the event that title to any Mortgaged Property is acquired in foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale shall be taken in the name of the related Trust, or in the event the related Trust is not authorized or permitted to hold title to real property in the state where the REO Property is located, or would be adversely affected under the “doing business” or tax laws of such state by so holding title, the deed or certificate of sale shall be taken in the name of such Person or Persons as shall be consistent with an Opinion of Counsel obtained by the Servicer from any attorney duly licensed to practice law in the state where the REO Property is located. The Person or Persons holding such title other than the related Trust shall acknowledge in writing that such title is being held as nominee for the related Trust.

The Servicer shall manage, conserve, protect and operate each REO Property for the related Trust solely for the purpose of its prompt disposition and sale. The Servicer, either itself or through an agent selected by the Servicer, shall manage, conserve, protect and operate such REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account, and in the same manner that similar property in the same locality as the REO Property is managed. The Servicer shall attempt to sell the same (and may temporarily rent the same for a period not greater than one year, except as otherwise provided below) on such terms and conditions as the Servicer deems to be in the best interest of the related Trust.

Notwithstanding anything to the contrary contained in this Section 3.12, in connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in the event the Servicer has reasonable cause to believe that a Mortgaged Property is contaminated by hazardous or toxic substances or wastes, or if the Master Servicer otherwise requests, an environmental inspection or review of such Mortgaged Property to be conducted by a qualified inspector shall be arranged by the Servicer. Upon completion of the inspection, the Servicer shall provide the Master Servicer and the Certificate Insurer with a written report of such environmental inspection. In the event that the environmental inspection report indicates that the Mortgaged Property is contaminated by hazardous or toxic substances or wastes, the Servicer shall not proceed with foreclosure or acceptance of a deed in lieu of foreclosure. In the event that the environmental inspection report is inconclusive as to the whether or not the Mortgaged Property is contaminated by hazardous or toxic substances or wastes, the Servicer shall not, without the prior written approval of the Master Servicer and the Certificate Insurer, proceed with foreclosure or acceptance of a deed in lieu of foreclosure. The Servicer shall be reimbursed for all Servicing Advances made pursuant to this paragraph with respect to the related Mortgaged Property from the amounts on deposit in the Custodial Account with respect to Securitized Loans in the same Trust.

In the event that a Trust which has made one or more REMIC elections acquires any REO Property in connection with a default or imminent default on a Securitized Loan, the Servicer shall dispose of such REO Property not later than the end of the third taxable year after the year of its acquisition by the related Trust unless the Servicer has applied for and received a grant of extension from the Internal Revenue Service (and provides a copy of the same to the Master Servicer) to the effect that, under the REMIC Provisions and any relevant proposed legislation and under applicable state law, a REMIC elected by such Trust may hold REO Property for a longer period without adversely affecting the REMIC status of such REMIC or causing the imposition of a federal or state tax upon such REMIC. If the Servicer has received such an extension (and provided a copy of the same to the Master Servicer), then the Servicer shall continue to attempt to sell the REO Property for its fair market value for such period longer than three years as such extension permits (the “Extended Period”). If the Servicer has not received such an extension, and the Servicer is unable to sell the REO Property within the period ending 3 months before the end of such third taxable year after its acquisition by the related Trust or if the Servicer has received such an extension, and the Servicer is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Servicer shall, before the end of the three-year period or the Extended Period, as applicable, (i) purchase such REO Property at a price equal to the REO Property’s fair market value or (ii) auction the REO Property to the highest bidder (which may be the Servicer) in an auction reasonably designed to produce a fair price prior to the expiration of the three-year period or the Extended Period, as the case may be. The related Trustee shall sign any document or take any other action reasonably requested by the Servicer which would enable the Servicer, on behalf of the related Trust, to request such grant of extension.

Notwithstanding any other provisions of this Agreement, no REO Property acquired by a Trust shall be rented (or allowed to continue to be rented) or otherwise used by or on behalf of such Trust in such a manner or pursuant to any terms that would: (i) cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code; or (ii) subject any REMIC elected by such Trust to the imposition of any federal income taxes on the income earned from such REO Property, including any taxes imposed by reason of Sections 860F or 860G(c) of the Code, unless the Servicer has agreed to indemnify and hold harmless such Trust with respect to the imposition of any such taxes.

The Servicer shall also maintain on each REO Property hazard insurance with extended coverage in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements which are a part of such property and (ii) the outstanding Principal Balance of the Securitized Loan at the time it becomes REO Property, to the extent required and available under the Flood Disaster Protection Act of 1973, as amended, flood insurance in the amount required above.

The disposition of REO Property shall be carried out by the Servicer at such price, and upon such terms and conditions, as the Servicer deems to be in the best interests of the related Trust. The proceeds of sale of the REO Property shall be promptly deposited in the Custodial Account. After the expenses of such disposition shall have been paid, the Servicer shall reimburse itself pursuant to Section 3.04 hereof for any Servicing Advances it incurred with respect to such REO Property.

The Servicer shall withdraw from the amounts on deposit in the Custodial Account with respect to Securitized Loans in the same Trust funds necessary for the proper operation, management and maintenance of the REO Property, including the cost of maintaining any hazard insurance pursuant to the Master Servicing Guide. The Servicer shall make monthly distributions on each Remittance Date to the Master Servicer of the net cash flow from the REO Property (which shall equal the revenues from such REO Property net of the expenses described in this Section 3.12 and of any reserves reasonably required from time to time to be maintained to satisfy anticipated liabilities for such expenses).

Section 3.13

Real Estate Owned Reports.

Together with the statement furnished pursuant to Section 4.02, the Servicer shall furnish by electronic transmission to the Master Servicer and the Certificate Insurer on or before the Remittance Date each month a statement with respect to any REO Property covering the operation of such REO Property for the previous month and the Servicer’s efforts in connection with the sale of such REO Property and any rental of such REO Property incidental to the sale thereof for the previous month. That statement shall be accompanied by such other information as the Master Servicer shall reasonably request.

Section 3.14

MERS.

(a)

The Seller shall take such actions as are necessary to cause the related Trust to be clearly identified as the owner of each MERS Securitized Loan on the records of MERS for purposes of the system of recording transfers of beneficial ownership of mortgages maintained by MERS.

(b)

The Servicer shall maintain in good standing its membership in MERS. In addition, the Servicer shall comply with all rules, policies and procedures of MERS, including the Rules of Membership, as amended, and the MERS Procedures Manual, as amended.

(c)

With respect to all MERS Securitized Loans serviced hereunder, the Servicer shall promptly notify MERS as to any transfer of beneficial ownership or release of any security interest in such Securitized Loans.

(d)

With respect to all MERS Securitized Loans serviced hereunder, the Servicer shall notify MERS as to any transfer of servicing pursuant to Section 9.01 within 10 Business Days of such transfer of servicing. The Servicer shall cooperate with each Trustee and any successor servicer to the extent necessary to ensure that such transfer of servicing is appropriately reflected on the MERS system.

Section 3.15

Waiver of Prepayment Penalties.

Except as provided below, the Servicer or any designee of the Servicer shall not waive any Prepayment Charge with respect to any Securitized Loan. If the Servicer or its designee fails to collect a Prepayment Charge at the time of the related prepayment of any Securitized Loan subject to such Prepayment Charge, the Servicer shall pay to the Trust at such time (by deposit to the Custodial Account) an amount equal to the amount of the Prepayment Charge not collected. The Seller warrants that the schedule of Prepayment Charges listed in each Transfer Notice shall be complete, true and accurate and may be relied on by the Servicer in its calculation of Prepayment Charges. Notwithstanding the above, the Servicer or its designee may waive a Prepayment Charge only if (i) the related prepayment is not the result of a refinancing by the Servicer or its designee, (ii) such waiver relates to a defaulted Securitized Loan or a reasonably foreseeable default, (iii) such waiver is standard and customary in servicing similar mortgage loans to the Securitized Loans, and (iv) such waiver, in the reasonable judgment of the Servicer, would maximize recovery of total proceeds from the Securitized Loan, taking into account the amount of such Prepayment Charge and the related Securitized Loan.

Section 3.16

Servicing and Administration of PMI Policies.

(a)

The Servicer shall take all such actions on behalf of the Trustee as are necessary to service, maintain and administer PMI Policies and to perform and enforce the rights under such Policies for the benefit of the related Trust. Except as expressly set forth herein, the Servicer shall have full authority on behalf of the related Trust to do anything it reasonably deems appropriate or desirable in connection with the servicing, maintenance and administration of the PMI Policies. The Servicer shall not modify or assume a Securitized Loan covered by a PMI Policy or take any other action with respect to such Securitized Loan which would result in non-coverage under any PMI Policy of any loss which, but for the actions of the Servicer, would have been covered thereunder. If a PMI Insurer fails to pay a claim under a PMI Policy as a result of breach by the Servicer of its obligations hereunder or under a PMI Policy, the Servicer shall be required to deposit in the Custodial Account on or prior to the next succeeding Remittance Date an amount equal to such unpaid claim from its own funds without any right to reimbursement from the related Trust. To the extent coverage is available, the Servicer shall keep or cause to be kept in full force and effect the Insurance Policies for as long as any Certificates issued by the related Trust are outstanding. The Servicer shall cooperate with each PMI Insurer and shall use its best efforts to furnish all reasonable aid, evidence and information in the possession of the Servicer to which the Servicer has access with respect to any Securitized Loan; provided, however, notwithstanding anything to the contrary contained in a PMI Policy, the Servicer shall not be required to submit any reports to a PMI Insurer until a reporting date that is at least 15 days after the Servicer has received sufficient loan level information from the Seller to appropriately code its servicing system in accordance with such PMI Insurer’s requirements.

(b)

The Servicer shall deposit into the Custodial Account pursuant to Section 3.03(xiii) hereof all Insurance Proceeds received from the PMI Insurer under the terms of a PMI Policy.

(c)

Notwithstanding the provisions of (a) and (b) above, the Servicer shall not take any action in regard to any PMI Policy inconsistent with the interests of the related Trust or the related Certificateholders or with the rights and interests of the related Trust or the related Certificateholders under this Agreement.

(d)

The related Trustee shall furnish the Servicer with any powers of attorney and other documents (within fifteen (15) days upon request from the Servicer) in form as provided to it necessary or appropriate to enable the Servicer to service and administer any PMI Policy; provided, however, that the related Trustee shall not be liable for the actions of the Servicer under such powers of attorney.

Section 3.17

Maintenance of Hazard Insurance.

The Servicer shall cause to be maintained for each Securitized Loan hazard insurance such that all buildings upon the related Mortgaged Property are insured by a generally acceptable insurer against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where such Mortgaged Property is located in an amount which is at least equal to the lesser of (i) the current principal balance of such Securitized Loan and (ii) the amount necessary to fully compensate for any damage or loss to the improvements that are a part of such property on a replacement cost basis, in each case in an amount not less than the amount as is necessary to avoid the application of any co-insurance clause contained in the related hazard insurance policy.

Any payments by the Servicer for hazard insurance, other than as set forth in the last paragraph of this Section 3.17, shall be deemed Servicing Advances, reimbursable in accordance with Section 3.04(vii) or (x), to the extent not collected from the related Mortgagor. The Servicer will comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any such hazard policies. Any amounts to be collected by the Servicer under any such policies (other than amounts to be applied to the restoration or repair of the property or amounts to be released to the Mortgagor subject to the terms and conditions of the related Mortgage and Mortgage Note) shall be deposited in the Custodial Account, subject to withdrawal pursuant to Section 3.04, if received in respect of a Securitized Loan. Any cost incurred by the Servicer in maintaining any such insurance shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid principal balance of the related Securitized Loan, notwithstanding that the terms of such Securitized Loan so permit. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If a Mortgaged Property or REO Property is at any time in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards and flood insurance has been made available, the Servicer will cause to be maintained a flood insurance policy in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the unpaid principal balance of the related Securitized Loan and (ii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program (assuming that the area in which such Mortgaged Property is located is participating in such program).

In the event that the Servicer shall obtain and maintain a blanket policy with an insurer having a General Policy Rating of B:III or better in Best’s Key Rating Guide (or such other rating that is comparable to such rating) insuring against hazard losses on all of the Securitized Loans in a Trust, it shall conclusively be deemed to have satisfied its obligations as set forth in the first two sentences of this Section 3.17 with respect to the Securitized Loans in such Trust, it being understood and agreed that such policy may contain a deductible clause, in which case the Servicer shall, in the event that there shall not have been maintained on the related Mortgaged Property or REO Property a policy complying with the first two sentences of this Section 3.17, and there shall have been one or more losses which would have been covered by such policy, deposit to the Custodial Account from its own funds without right of reimbursement the amount not otherwise payable under the blanket policy because of such deductible clause for the benefit of the related Trust. In connection with its activities as administrator and servicer of the Securitized Loans, the Servicer agrees to prepare and present, on behalf of itself, the Trust and the Certificateholders, claims under any such blanket policy in a timely fashion in accordance with the terms of such policy. Copies of such claims shall be provided to the Certificate Insurer.

Section 3.18

Realization Upon Defaulted Securitized Loans.

(a)

The Servicer shall use its best efforts and, consistent with Accepted Servicing Practices, foreclose upon or otherwise comparably convert the ownership of properties securing such of the Securitized Loans (including selling any such Securitized Loans other than converting the ownership of the related properties) as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. The Servicer shall be responsible for all costs and expenses incurred by it in any such proceedings; provided, however, that such costs and expenses will be recoverable as Servicing Advances by the Servicer as contemplated in Section 3.04. The foregoing is subject to the provision that, in any case in which a Mortgaged Property shall have suffered damage from an uninsured cause, the Servicer shall not be required to expend its own funds toward the restoration of such Mortgaged Property unless it has determined that such restoration will increase the proceeds of liquidation of the related Securitized Loan after reimbursement to itself for such expenses. In instituting foreclosures or other similar proceedings, the Servicer shall institute such proceedings in its own name on behalf of the related Trust, unless otherwise required by applicable law or otherwise appropriate.

(b)

If the Servicer determines that it is in the best economic interest of a Trust and the Certificateholders to sell a Distressed Securitized Loan rather than foreclosing, the Servicer may effect such a sale. The net proceeds of such sale shall be Liquidation Proceeds.

(c)

Proceeds received in connection with any Final Recovery Determination, as well as any recovery resulting from a partial collection of Insurance Proceeds, Liquidation Proceeds or Condemnation Proceeds, in respect of any Securitized Loan, will be applied in the following order of priority: first, to unpaid Servicing Fees; second, to reimburse the Servicer for any related unreimbursed Servicing Advances and Monthly Advances pursuant to Section 3.04; third, to accrued and unpaid interest on the Securitized Loan, to the date of the Final Recovery Determination, or to the Due Date prior to the Remittance Date on which such amounts are to be remitted to the Master Servicer if not in connection with a Final Recovery Determination; and fourth, as a recovery of principal of the Securitized Loan. The portion of the recovery so allocated to any unpaid Servicing Fee shall be reimbursed to the Servicer pursuant to Section 3.04.

Section 3.19

Enforcement of Due-On-Sale Clauses; Assumption Agreement.

The Servicer will, to the extent it has knowledge of any conveyance or prospective conveyance of any Mortgaged Property by any Mortgagor (whether by absolute conveyance or contract of sale, and whether or not the Mortgagor remains or is to remain liable under the Mortgage Note and/or the Mortgage), exercise its rights to accelerate the maturity of such Securitized Loan under the "due-on-sale" clause, if any, applicable thereto; provided, however, that the Servicer shall not be required to take such action if in its sole business judgment the Servicer believes it is not in the best interests of the related Trust and shall not exercise any such rights if prohibited by law from doing so. If the Servicer reasonably believes it is unable under applicable law to enforce such "due-on-sale" clause, or if any of the other conditions set forth in the proviso to the preceding sentence apply, the Servicer will enter into an assumption and modification agreement from or with the person to whom such property has been conveyed or is proposed to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, to the extent permitted by applicable state law, the Mortgagor remains liable thereon. The Servicer is also authorized to enter into a substitution of liability agreement with such person, pursuant to which the original Mortgagor is released from liability and such person is substituted as the Mortgagor and becomes liable under the Mortgage Note, provided that no such substitution shall be effective unless such person satisfies the underwriting criteria of the Servicer and has a credit risk rating at least equal to that of the original Mortgagor. In connection with any assumption or substitution, the Servicer shall apply such underwriting standards and follow such practices and procedures as shall be normal and usual in its general mortgage servicing activities and as it applies to other mortgage loans owned solely by it. The Servicer shall not take or enter into any assumption and modification agreement, however, unless (to the extent practicable in the circumstances) it shall have received confirmation, in writing, of the continued effectiveness of any applicable hazard insurance policy. Any fee collected by the Servicer in respect of an assumption, modification or substitution of liability agreement shall be retained by the Servicer as additional servicing compensation. In connection with any such assumption, no material term of the Mortgage Note (including but not limited to the related Mortgage Interest Rate and the amount of the Monthly Payment) may be amended or modified, except as otherwise required pursuant to the terms thereof. The Servicer shall notify the related Trustee that any such substitution, modification or assumption agreement has been completed by the Servicer, and the Servicer shall deliver to the Custodian the executed original of such substitution, modification or assumption agreement, which document shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof, and the Servicer shall also deliver to the Trustee a copy of the executed substitution, modification or assumption agreement.

Notwithstanding the foregoing paragraph or any other provision of this Agreement, the Servicer shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any assumption of a Securitized Loan by operation of law or by the terms of the Mortgage Note or any assumption which the Servicer may be restricted by law from preventing, for any reason whatever. For purposes of this Section 3.19, the term "assumption" is deemed to also include a sale (of the Mortgaged Property) subject to the Mortgage that is not accompanied by an assumption or substitution of liability agreement.

Section 3.20

Credit Risk Manager.

The Servicer acknowledges and agrees that, under any Trust Agreement, a Credit Risk Manager may be required to provide certain credit risk management services as provided therein. If so, the Servicer hereby agrees to cooperate with the Credit Risk Manager in connection with all reasonable requests made by the Credit Risk Manager, including, without limitation, promptly providing copies of any servicing reports and remittance advices required under this Agreement to the Credit Risk Manager.

Section 3.21

Compliance with Applicable Laws.

All requirements of any federal, state or local law (including usury, truth in lending, real estate settlement procedures, consumer credit protection, equal credit opportunity, disclosure or recording, predatory and abusive lending laws) applicable to the servicing of the Securitized Loans will be complied with by the Servicer in all material respects.

ARTICLE IV.

PAYMENTS TO MASTER SERVICER

Section 4.01

Remittances.

On each Remittance Date, no later than 3:00 p.m. New York City time, the Servicer shall remit on a scheduled/scheduled basis by wire transfer of immediately available funds to the Master Servicer (a) all amounts deposited in the Custodial Account as of the close of business on the Determination Date (net of charges against or withdrawals from the Custodial Account pursuant to Section 3.04), plus (b) all Monthly Advances, if any, which the Servicer or other Advancing Person is obligated to make pursuant to Section 4.03, minus (c) any amounts attributable to Principal Prepayments, Liquidation Proceeds, Insurance Proceeds, Condemnation Proceeds or REO Disposition Proceeds received after the applicable Due Period, which amounts shall be remitted on the following Remittance Date, together with any additional interest required to be deposited in the Custodial Account in connection with such Principal Prepayment in accordance with Section 3.03 (iii) and (vii), and minus (d) any amounts attributable to Monthly Payments collected but due on a Due Date or Due Dates subsequent to the first day of the month in which such Remittance Date occurs, which amounts shall be remitted on the Remittance Date next succeeding the Due Date related to such Monthly Payment.

With respect to any remittance received by the Master Servicer after the Business Day on which such payment was due, the Servicer shall pay to the Master Servicer interest on any such late payment at an annual rate equal to LIBOR, adjusted as of the date of each change, plus four (4) percentage points, but in no event greater than the maximum amount permitted by applicable law. Such interest shall be deposited in the Custodial Account by the Servicer on the date such late payment is made and shall cover the period commencing with the day following the Remittance Date and ending with the Business Day on which such payment is made, both inclusive. Such interest shall be remitted along with the distribution payable on the next succeeding Remittance Date. The payment by the Servicer of any such interest shall not be deemed an extension of time for payment or a waiver of any breach or Event of Default by the Master Servicer or any applicable Trustee.

All remittances required to be made to the Master Servicer shall be made on a scheduled/scheduled basis in accordance with the wire transfer instructions as may be specified by the Master Servicer to the Servicer from time to time.

Section 4.02

Statements to Master Servicer.

Not later than the 10th calendar day of each month (or if such calendar day is not a Business Day, the immediately succeeding Business Day), the Servicer shall furnish to the Master Servicer and the Certificate Insurer with respect to each related Trust, or as the Servicer and the Master Servicer may otherwise agree (a) a monthly remittance advice in the format set forth at Exhibit D hereto with regard to monthly loan remittance data, Exhibit E with regard to default mortgage loans, and Exhibit F with regard to realized losses or gains for the period ending on the first day of such calendar month (i.e., the Due Period) and (b) all such information required pursuant to clause (a) above in an electronic file or other similar media reasonably acceptable to the Master Servicer. The Servicer shall also furnish to the Master Servicer and the Certificate Insurer (in such format mutually agreed to by the Servicer and the Master Servicer) a monthly report detailing loan level Prepayment Charges collected and/or waived by the Servicer in accordance with Section 3.15.

Such monthly remittance advice shall also be accompanied with a supplemental report provided to the Master Servicer which includes on an aggregate basis for the previous Due Period (i) the amount of claims filed, (ii) the amount of any claim payments made, (iii) the amount of claims denied or curtailed and (iv) policies cancelled with respect to those Securitized Loans covered by any PMI Policy or any other provider of primary mortgage insurance purchased by the Trust. Notwithstanding anything to the contrary contained in a PMI Policy, the Servicer shall not be required to submit any supplemental reports including the foregoing data with respect to a PMI Policy until a reporting date that is at least 15 days after the Servicer has received sufficient loan level information from the Seller to appropriately code its servicing system in accordance with requirements.

In addition, not more than 60 days after the end of each calendar year, commencing December 31, 2006, the Servicer shall provide (as such information becomes reasonably available to the Servicer) to the Master Servicer such information concerning the Securitized Loans and annual remittances to the Master Servicer with respect to the Securitized Loans in each Trust as is necessary for each Certificateholder and the Certificate Insurer to prepare its federal income tax return. Such obligation of the Servicer shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Servicer to the Master Servicer and pursuant to any requirements of the Code as from time to time are in force.

Beginning with calendar year 2006, the Servicer shall provide the Master Servicer and each Trustee with such information concerning the related Securitized Loans as is necessary for such Trustee to prepare the related Trust’s federal income tax return and for any investor in the related Certificates to prepare any required tax return.

Section 4.03

Monthly Advances by Servicer.

On the Business Day immediately preceding each Remittance Date, the Servicer shall deposit in the Custodial Account from its own funds or from amounts held for future distribution, or both, an amount equal to the aggregate of all Monthly Advances relating to Monthly Payments which were due on the Securitized Loans during the applicable Due Period and which were delinquent at the close of business on the immediately preceding Determination Date. Any amounts held for future distribution and so used shall be replaced by the Servicer by deposit in the Custodial Account on or before any future Remittance Date if funds in the Custodial Account on such Remittance Date shall be less than remittances to the Master Servicer required to be made on such Remittance Date. The Servicer shall keep appropriate records of such amounts and will provide such records to the Master Servicer upon request. No provision in this Agreement shall be construed as limiting the Servicer’s right to (i) pass through late collections on the related Securitized Loans in lieu of making Monthly Advances (ii) reimburse itself for such Monthly Advances from late collections on the related Securitized Loans or (iii) utilize an Advancing Person (as defined below).

The Servicer's obligation to make such Monthly Advances as to any Securitized Loan will continue through the last Monthly Payment due prior to the payment in full of the Securitized Loan, or through the last Remittance Date prior to the Remittance Date for the distribution of all Liquidation Proceeds and other payments or recoveries (including REO Disposition Proceeds, Insurance Proceeds and Condemnation Proceeds) with respect to the Securitized Loan; provided, however, that such obligation shall cease if the Servicer determines, in its sole reasonable opinion in accordance with Accepted Servicing Practices, that advances with respect to such Securitized Loan are non-recoverable by the Servicer from Liquidation Proceeds, Insurance Proceeds, Condemnation Proceeds, or otherwise with respect to a particular Securitized Loan.

Section 4.04

Compensating Interest.

The Servicer shall be required to deposit in the Custodial Account, and retain therein with respect to each Principal Prepayment, the Prepayment Interest Shortfall Amount, if any, for the related Due Period. Such deposit shall be made from the Servicer’s own funds, without reimbursement therefor, up to an amount equal to the lesser of with respect to the Securitized Loans in each Trust (i) the Prepayment Interest Shortfall Amount or (ii) the Servicing Fee, in each case, with respect to the Securitized Loans in such Trust.

Section 5.01

Servicing Compensation.

As consideration for servicing the Securitized Loans subject to this Agreement, the Servicer shall retain (a) the Servicing Fee for each Securitized Loan remaining subject to this Agreement during any month and (b) Ancillary Income. The Servicing Fee shall be payable monthly. Notwithstanding the foregoing, it is acknowledged that so long as the Seller owns the servicing rights with respect to a Securitized Loan, a portion of the servicing fee (in an amount agreed to between the Seller and the Servicer) shall be remitted by the Servicer to the Seller upon collection thereof in accordance with a certain agreement between the Seller and the Servicer.

The Servicer shall be entitled to recover any unpaid Servicing Fee out of Insurance Proceeds, Condemnation Proceeds or Liquidation Proceeds to the extent permitted in Section 3.04 and out of amounts derived from the operation and sale of an REO Property to the extent permitted by Section 3.12.

Additional servicing compensation in the form of Ancillary Income shall be retained by the Servicer only to the extent such fees or charges are received by the Servicer. The Servicer shall also be entitled pursuant to Section 3.04 and Section 3.06 to withdraw from the Custodial Account and Escrow Account, respectively, as additional servicing compensation, interest or other income earned on deposits therein, subject to Section 3.11.

The Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder, including any fees due to sub-servicers, and shall not be entitled to reimbursement thereof except as specifically provided for herein or pursuant to a separate agreement between Seller and Servicer.

(i)

Based on my knowledge, the information in the annual statement of compliance furnished pursuant to Section 5.03, the annual independent public accountant’s servicing report furnished pursuant to Section 5.02 and all servicing reports, officer’s certificates and other information relating to the servicing of the Securitized Loans submitted to the Master Servicer taken as a whole, does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading as of the date of this certification;

(ii)

The servicing information required to be provided to the Master Servicer by the Servicer under this Agreement has been provided to the Master Servicer;

(iii)

I am responsible for reviewing the activities performed by the Servicer under the Agreement and based upon the review required by the Agreement, and except as disclosed in the annual statement of compliance, the annual independent public accountant’s servicing report and all servicing reports, officer’s certificates and other information relating to the servicing of the Securitized Loans submitted to the Master Servicer, the Servicer has, as of the date of this certification fulfilled its obligations under the Agreement; and

If the indemnification provided for herein is unavailable or insufficient to hold harmless the Master Servicer, then the Servicer agrees that it shall contribute to the amount paid or payable by the Master Servicer as a result of losses, claims, damages or liabilities of the Master Servicer in such proportion as is appropriate to reflect the relative fault of the Master Servicer on the one hand and the Servicer on the other in connection with a breach of the Servicer’s obligations under Sections 5.02, 5.03 or 5.04 or the Servicer’s negligence, bad faith or willful misconduct in connection therewith.

Remedies for Breach of Representations and Warranties of the Servicer.

It is understood and agreed that the representations and warranties set forth in Section 6.01 shall survive the engagement of the Servicer to perform the servicing responsibilities as of any Closing Date hereunder and the delivery of the Servicing Files to the Servicer and shall inure to the benefit of the Seller, any Depositor, the Master Servicer and each Trust, Certificate Insurer and Trustee. Upon discovery by any of the Servicer, the Master Servicer, the Trustee, Certificate Insurer, any Depositor or the Seller of a breach of any of the foregoing representations and warranties which materially and adversely affects the ability of the Servicer to perform its duties and obligations under this Agreement or otherwise materially and adversely affects the value of the Securitized Loans, the Mortgaged Property, the priority of the security interest on such Mortgaged Property or the interest of the Seller, any Depositor, the Master Servicer, Certificate Insurer, the related Trust or the related Trustee, the party discovering such breach shall give prompt written notice to the others.

Within 60 days of the earlier of either discovery by or notice to the Servicer of a breach of a representation or warranty set forth in Section 6.01 which materially and adversely affects the ability of the Servicer to perform its duties and obligations under this Agreement or otherwise materially and adversely affects the value of the Securitized Loans, the Mortgaged Property or the priority of the security interest on such Mortgaged Property, the Servicer shall use its best efforts promptly to cure such breach in all material respects and, if such breach cannot be cured, the Servicer shall, at the option of the Master Servicer, assign the Servicer’s rights and obligations under this Agreement (or respecting the affected Securitized Loans) with respect to a Trust to a successor servicer selected by the Master Servicer with the prior consent and approval of the Trustee. Such assignment shall be made in accordance with Section 9.01 and 9.02.

In addition, the Servicer shall indemnify the Seller, the Master Servicer, Certificate Insurer, any Depositor and each Trustee and hold each of them harmless against any Costs resulting from any claim, demand, defense or assertion based on or grounded upon, or resulting from, a breach of the Servicer's representations and warranties contained in this Agreement. It is understood and agreed that the remedies set forth in this Section 6.02 constitute the sole remedies of the Seller, the Master Servicer, any Depositor, and each Trust and Trustee hereunder respecting a breach of the foregoing representations and warranties.

Any cause of action against the Servicer relating to or arising out of the breach of any representations and warranties made in Section 6.01 shall accrue upon (i) discovery of such breach by the Servicer or notice thereof by the Seller, the Master Servicer, Certificate Insurer, any Depositor or a Trustee to the Servicer, (ii) failure by the Servicer to cure such breach within the applicable cure period, and (iii) demand upon the Servicer by the Seller, any Depositor, Certificate Insurer, the Master Servicer or a Trustee for compliance with this Agreement.

The Servicer shall indemnify the Seller, any Depositor, Certificate Insurer, each Trustee, the Master Servicer and each Trust and hold them harmless against any and all Costs that any such indemnified party may sustain in any way related to (i) the failure of the Servicer to perform its duties and service the related Securitized Loans in material compliance with the terms of this Agreement or (ii) the failure of the Servicer to cause any event to occur which would have occurred if the Servicer were applying Accepted Servicing Practices under this Agreement. The Servicer shall immediately notify the Seller, any related Depositor, Certificate Insurer, the Master Servicer, the related Trustee or any other relevant party if a claim is made by a third party with respect to this Agreement or the related Securitized Loans, assume (with the prior written consent of the indemnified party) the defense of any such claim and pay all expenses in connection therewith, including counsel fees, promptly pay, discharge and satisfy any judgment or decree which may be entered against it or any indemnified party in respect of such claim and follow any written instructions received from such indemnified party in connection with such claim. The Servicer shall be promptly reimbursed by the related Trust or Trusts for all amounts advanced by it pursuant to the preceding sentence except when the claim is in any way related to the Servicer’s indemnification pursuant to Section 6.02, or the failure of the Servicer to service and administer the Securitized Loans in material compliance with the terms of this Agreement. In the event a dispute arises between an indemnified party and the Servicer with respect to any of the rights and obligations of the parties pursuant to this Agreement, and such dispute is adjudicated in a court of law, by an arbitration panel or any other judicial process, then the losing party shall indemnify and reimburse the winning party for all attorneys’ fees and other costs and expenses related to the adjudication of said dispute.

Section 6.04

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

In the event that any REMIC elected by a Trust fails to qualify as a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a result of a prohibited transaction or prohibited contribution under the REMIC Provisions due to the negligent performance by the Servicer of its duties and obligations set forth herein, the Servicer shall indemnify the Holder of the related Residual Certificate, the Master Servicer, the related Trustee and the related Trust against any and all losses, claims, damages, liabilities or expenses (“Losses”) resulting from such negligence; provided, however, that the Servicer shall not be liable for any such Losses attributable to the action or inaction of the related Trustee, any related Depositor, the Master Servicer or the Holder of such Residual Certificate, as applicable, nor for any such Losses resulting from misinformation provided by the Holder of such Residual Certificate or any such other party on which the Servicer has relied. The foregoing shall not be deemed to limit or restrict the rights and remedies of the Holder of such Residual Certificate or the related Trust now or hereafter existing at law or in equity or otherwise. Notwithstanding the foregoing, however, in no event shall the Servicer have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement, (2) for any Losses other than arising out of a negligent performance by the Servicer of its duties and obligations set forth herein, and (3) for any special or consequential damages to the related Certificateholders.

THE SERVICER

Section 7.01

The Servicer shall keep in full effect its existence, rights and franchises as a corporation, and shall obtain and preserve its qualification to do business as a foreign entity in each jurisdiction in which such qualification is or shall be necessary to perform its obligations as contemplated by this Agreement.

Any Person into which the Servicer may be merged or consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Servicer shall be a party, or any Person succeeding to the business of the Servicer, shall, with the prior written consent of the Master Servicer, be the successor of the Servicer hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or surviving Person shall be an institution (i) having a net worth of not less than $25,000,000, and (ii) which is a ▇▇▇▇▇▇▇ Mac-approved or ▇▇▇▇▇▇ Mae-approved servicer in good standing.

Section 7.02

Limitation on Liability of the Servicer and Others.

The Servicer nor any of the directors, officers, employees or agents of the Servicer shall be under any liability to the Seller, the Master Servicer, any Depositor, any Trust or any Trustee hereunder for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Servicer or any such Person against any breach of warranties or representations made herein, or failure to perform its obligations in strict compliance with any standard of care set forth in this Agreement, or any liability which would otherwise be imposed by reason of any breach of the terms and conditions of this Agreement. The Servicer and any director, officer, employee or agent of the Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Servicer shall not be under any obligation to appear in, prosecute or defend any legal action which is not incidental to its duties to service the Securitized Loans in accordance with this Agreement and which in its opinion may involve it in any expense or liability; provided, however, that the Servicer may, with the consent of the related Trustee, Certificate Insurer and the Master Servicer, undertake any such action which it deems necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto. In such event, the Servicer shall be entitled to reimbursement from the related Trust for the reasonable legal expenses and costs of such action.

Section 7.03

Limitation on Resignation and Assignment by the Servicer.

(a) The Servicer may not assign its rights under this Agreement or the servicing hereunder without the prior written consent of the Seller and the Master Servicer. Unless expressly permitted under this Agreement, the Servicer may not delegate its duties hereunder or any portion thereof, or sell or otherwise dispose of all or substantially all of its property or assets without the consent of the Seller and the Master Servicer.

(b)

Other than as provided in subparts (a) and (d) of this Section 7.03, the Servicer shall not resign from the obligations and duties hereby imposed on it with respect to the Securitized Loans in a Trust except by mutual consent of the Seller, the Master Servicer and the related Trustee, with the consent of the Certificate Insurer, or upon the determination that its duties hereunder are no longer permissible under applicable law and such incapacity cannot be cured by the Servicer. Any such determination permitting the resignation of the Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Seller, the Master Servicer and the related Trustee and Certificate Insurer which Opinion of Counsel shall be in form and substance acceptable to the Seller, the Master Servicer and the related Trustee and Certificate Insurer. No resignation of the Servicer shall become effective until a successor acceptable to the Master Servicer shall have assumed the Servicer’s responsibilities and obligations hereunder in the manner provided in Section 9.01.

(c)

Without in any way limiting the generality of this Section 7.03, in the event that the Servicer either shall assign this Agreement or the servicing responsibilities hereunder or delegate its duties hereunder or any portion thereof or sell or otherwise dispose of all or substantially all of its property or assets, without the prior written consent of the Seller, the Master Servicer and the Trustee and Certificate Insurer (except as provided by the first paragraph of this Section 7.03 and Section 7.04), then such parties shall have the right to terminate this Agreement upon notice given as set forth in Section 8.01, without any payment of any penalty or damages and without any liability whatsoever to the Servicer or any third party.

(d)

Notwithstanding the foregoing, at the Seller’s request, so long as it is the owner of the servicing rights with respect to any Securitized Loans, the Servicer shall resign as servicer of any Securitized Loans upon the Seller’s selection and appointment of a successor servicer with respect to such Securitized Loans; provided that the Seller delivers to the Master Servicer, the Trustee and any related Certificate Insurer a letter from the applicable Rating Agency or Rating Agencies to the effect that the related transfer of servicing will not result in a qualification, withdrawal or downgrade of the then-current rating of any of the Certificates.

Section 7.04

Sub-Servicing Agreements; Sub-Servicing Acknowledgment Agreement; Successor Sub-Servicer.

(a)

The Servicer, with the consent of the Certificate Insurer, may arrange for the subservicing of any Securitized Loan by a Subservicer pursuant to a Subservicing Agreement; provided that such Subservicing arrangement and the terms of the related Subservicing Agreement must provide for the servicing of such Securitized Loans in a manner consistent with the servicing arrangements contemplated hereunder. Each Subservicer (i) shall be an approved ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac Seller/Servicer as indicated in writing, and (ii) shall represent and warrant that it is in compliance with the laws of each state as necessary to enable it to perform its obligations under such Subservicing agreement. For this purpose, sub-servicing shall not be deemed to include the use of a tax service, or services for reconveyance, insurance or brokering REO Property. The Servicer shall give prior written notice to the Master Servicer, the Trustee and Certificate Insurer of the appointment of any sub-servicer and shall furnish to the Master Servicer, the Trustee and Certificate Insurer a copy of such sub-servicing agreement. For purposes of this Agreement, the Servicer shall be deemed to have received payments on Securitized Loans immediately upon receipt by any sub-servicer of such payments. Any such sub-servicing agreement shall be acceptable to the Master Servicer and the related Trustee and Certificate Insurer and shall be consistent with and not violate the provisions of this Agreement. Every Subservicing Agreement entered into by the Servicer shall contain a provision giving the successor servicer the option to terminate, without fee, such agreement in the event a successor servicer is appointed. All actions of each Subservicer performed pursuant to the related Subservicing Agreement shall be performed as an agent of the Servicer with the same force and effect as if performed directly by the Servicer.

For purposes of this Agreement, the Servicer shall be deemed to have received any collections, recoveries or payments with respect to the Securitized Loans that are received by a Subservicer regardless of whether such payments are remitted by the Subservicer to the Servicer.

(b)

The Servicer, with the consent of the Certificate Insurer and Master Servicer, may terminate any sub-servicing agreement to which it is a party in accordance with the terms and conditions of such sub-servicing agreement and either itself directly service the related Securitized Loans or enter into a sub-servicing agreement with a successor sub-servicer that qualifies under Section 7.04(a).

(c)

Notwithstanding any sub-servicing agreement or the provisions of this Agreement relating to agreements or arrangements between the Servicer and a sub-servicer or reference to actions taken through a sub-servicer or otherwise, the Servicer shall remain obligated and primarily liable to the Trustee, the Master Servicer, the Trust and the Certificateholders for the servicing and administering of the Securitized Loans in accordance with the provisions hereof without diminution of such obligation or liability by virtue of such sub-servicing agreements or arrangements or by virtue of indemnification from the sub-servicer and to the same extent and under the same terms and conditions as if the Servicer alone were servicing and administering the Securitized Loans. The Servicer shall be entitled to enter into any agreement with a sub-servicer for indemnification of the Servicer by such sub-servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

(d)

Any Subservicing Agreement and any other transactions or services relating to the Securitized Loans involving a Subservicer shall be deemed to be between the Subservicer and the Servicer alone and none of the Seller, the Master Servicer nor the Trust or Trustee shall be deemed a party thereto and shall have no claims, rights, obligations, duties or liabilities with respect to any Subservicer except as set forth in subpart (e) below.

(e)

In connection with the assumption of the responsibilities, duties and liabilities and of the authority, power and rights of the Servicer hereunder by a successor servicer pursuant to Section 9.01 of the Agreement, it is understood and agreed that the Servicer’s rights and obligations under any Subservicing Agreement then in force between the Servicer and a Subservicer shall be assumed simultaneously by such successor servicer without act or deed on the part of such successor servicer; provided, however, that any successor servicer may terminate the Subservicer. The Servicer shall, upon the reasonable request of the Seller or the Master Servicer, but at its own expense, deliver to the assuming party documents and records relating to each Subservicing Agreement and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the Subservicing Agreements to the assuming party. The Servicing Fee payable to any such successor servicer shall be payable from payments received on the Securitized Loans in the amount and in the manner set forth in this Agreement.

Section 7.05

Inspection.

The Servicer shall offer each Trustee, Certificate Insurer and the Master Servicer, upon reasonable advance notice, during normal business hours, access to all records maintained by the Servicer in respect of its rights and obligations hereunder and access to officers of the Servicer responsible for such obligations. Upon request, the Servicer shall furnish to each Trustee, Certificate Insurer and the Master Servicer its most recent publicly available financial statements and such other information relating to its, together with its designated sub-servicer, capacity to perform its obligations under this Agreement.

ARTICLE VIII.

TERMINATION

Section 8.01

Termination for Cause.

This Agreement shall be terminable at the option of the Master Servicer or the related Trustee if any of the following events of default exist on the part of the Servicer after the expiration of any applicable cure period:

(i)

any failure by the Servicer to remit to the Master Servicer any payment required to be made under the terms of this Agreement which continues unremedied for a period of one Business Day after the date upon which written notice of such failure, requiring the same to be remedied, shall have been received by the Servicer from the Master Servicer, the Certificate Insurer or a related Trustee; or

(ii)

failure by the Servicer duly to observe or perform in any material respect any other of the covenants or agreements on the part of the Servicer set forth in this Agreement (except with respect to its obligations under Section 5.02, 5.03 or 5.04) which continues unremedied for a period of 15 days following the Servicer’s receipt of written notice of such failure from the Master Servicer, the Certificate Insurer or a related Trustee; or

(iii)

failure by the Servicer to maintain its license to do business or service residential Securitized Loans in any jurisdiction, if required by such jurisdiction, where a related Mortgaged Property is located;

a decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, including bankruptcy, marshaling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; or

(v)

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

(vi)

the 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, bankruptcy or reorganization statute, make an assignment for the benefit of its creditors, voluntarily suspend payment of its obligations or cease its normal business operations for three Business Days; or

(vii)

the Servicer ceases to meet the qualifications of a ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac seller/servicer; or

In each and every such case, so long as an event of default shall not have been remedied within the applicable cure period, in addition to whatever rights the Master Servicer or a related Trustee may have at law or equity to damages, including injunctive relief and specific performance, the Trustee or the Master Servicer, by notice in writing to the Servicer, and with the consent of the other party, may (and, at the request of the Certificate Insurer, shall) terminate all the rights and obligations of the Servicer under this Agreement and in and to the servicing contract established hereby and the proceeds thereof.

Upon receipt by the Servicer of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Securitized Loans or otherwise, shall pass to and be vested in a successor servicer appointed by the Trustee or the Master Servicer, as the case may be, with the consent of the other party and the Certificate Insurer. Upon written request from the Master Servicer, the Servicer shall prepare, execute and deliver to the successor servicer or the Trustee any and all documents and other instruments, place in such successor’s possession all Servicing Files, and do or cause to be done all other acts or things necessary or appropriate to effect the purposes of such notice of termination, including but not limited to the transfer and endorsement or assignment of the Securitized Loans and related documents, at the Servicer’s sole expense. The Servicer shall cooperate with the Master Servicer and such successor in effecting the termination of the Servicer’s responsibilities and rights hereunder, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by the Servicer to the Custodial Account or Escrow Account or thereafter received with respect to the Securitized Loans.

By a written notice, the Trustee or the Master Servicer, with the consent of the other parties and the Certificate Insurer, may waive any default by the Servicer in the performance of its obligations hereunder and its consequences. Upon any waiver of a past default, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived.

In connection with any termination pursuant to clause (ii) of the first sentence of this Section 8.02(a), all unreimbursed Servicing Fees, Servicing Advances and Monthly Advances still owing the Servicer shall be paid at the time of such termination by the Trust.

Upon a termination of the Servicer for cause pursuant to Section 8.01, all unreimbursed Servicing Fees, Servicing Advances and Monthly Advances still owing the Servicer shall be paid by the Trust as such amounts are received from the related Securitized Loans. In connection with any termination pursuant to the second sentence of this Section 8.02(a), the Seller or its designee or the successor servicer will be responsible for reimbursing the Servicer for all unreimbursed out-of-pocket Servicing Advances, Monthly Advances and Servicing Fees and other reasonable and necessary out-of-pocket costs associated with any transfer of servicing at the time of such transfer of servicing. Any invoices received by the Servicer after termination will be forwarded to the Seller or its designee, and the Seller or its designee or the successor servicer shall pay such invoices within five (5) Business Days upon receipt from the Servicer.

(b)

In the event that the Servicer decides to terminate its obligations under this Agreement as set forth in clause (ii) of Section 8.02(a), the Servicer agrees that it will continue to service the Securitized Loans beyond the prescribed termination date until such time as the Master Servicer, using reasonable commercial efforts, is able to appoint, with the consent of the Certificate Insurer, a successor servicer acceptable to the Certificate Insurer and the Trustee and otherwise meeting the characteristics of Sections 7.01 and 9.01.

ARTICLE IX.

MISCELLANEOUS PROVISIONS

Section 9.01

Successor to the Servicer.

Simultaneously with the termination or resignation of the Servicer’s responsibilities and duties under this Agreement (a) pursuant to Sections 6.02, 7.03, 8.01 or 8.02(a)(ii), the Master Servicer shall (i) within 90 days of the Servicer’s receipt of notice of such termination, succeed to and assume all of the Servicer’s responsibilities, rights, duties and obligations under this Agreement (except that the Master Servicer shall immediately assume all of the obligations of the Servicer to make Monthly Advances), or (ii) appoint a successor acceptable to the Certificate Insurer having the characteristics set forth in clauses (i) and (ii) of Section 7.01 and which shall succeed to all rights and assume all of the responsibilities, duties and liabilities of the Servicer under this Agreement simultaneously with the termination of the Servicer’s responsibilities, duties and liabilities under this Agreement; or (b) as a result of termination of the Servicer without cause by the Seller pursuant to Section 8.02 hereof, the Seller shall appoint a successor acceptable to the Certificate Insurer and the Master Servicer having the characteristics set forth in clauses (i) and (ii) of Section 7.01 and which shall succeed to all rights and assume all of the responsibilities, duties and liabilities of the Servicer under this Agreement simultaneously with the termination of the Servicer’s responsibilities, duties and liabilities under this Agreement. If the Certificate Insurer requests, the Master Servicer shall appoint a successor servicer as provided in the preceding sentence. Any successor to the Servicer shall be subject to the approval of the Master Servicer and the Trustee and, to the extent required by the Trust Agreement, shall be a member in good standing of the MERS system (if any of the Securitized Loans are MERS Eligible Securitized Loans, unless such Securitized Loans are withdrawn from MERS and Assignments of Mortgage are recorded in favor of the Trust at the expense of the successor servicer). The final approval of a successor servicer shall be conditioned upon the receipt by the Trustee, the Master Servicer, Certificate Insurer and the Seller of a letter from the applicable Rating Agency or Rating Agencies to the effect that such transfer of servicing will not result in a qualification, withdrawal or downgrade of the then-current rating of any of the Certificates. In connection with such appointment and assumption, the Master Servicer or the Seller, as applicable, may make such arrangements for the compensation of such successor out of payments on Securitized Loans as it and such successor shall agree, provided, however, that no such compensation shall be in excess of the Servicing Fee permitted under this Agreement. In the event that the Servicer’s duties, responsibilities and liabilities under this Agreement should be terminated pursuant to the aforementioned sections, the Servicer shall discharge such duties and responsibilities during the period from the date it acquires knowledge of such termination until the effective date thereof with the same degree of diligence and prudence which it is obligated to exercise under this Agreement, and shall take no action whatsoever that might impair or prejudice the rights or financial condition of its successor. The resignation or removal of the Servicer pursuant to the aforementioned sections shall not become effective until a successor servicer shall be appointed pursuant to this Section 9.01, or until the Master Servicer succeeds to and assumes all of the Servicer’s responsibilities, rights, duties and obligations pursuant to this Section 9.01, and shall in no event relieve the Servicer of the representations and warranties made pursuant to Section 6.01 and the remedies available to the Trustee, the Trust, the Master Servicer, Certificate Insurer and the Seller under Section 6.02 and 6.03, it being understood and agreed that the provisions of such Sections 6.01, 6.02 and 6.03 shall be applicable not only to such successor servicer but also to the Servicer notwithstanding any such resignation or termination of the Servicer, or the termination of this Agreement. Notwithstanding the foregoing, the Master Servicer, in its capacity as successor servicer, shall not be responsible for the lack of information and/or documents that it cannot obtain through reasonable efforts.

Within a reasonable period of time, but in no event longer than 30 days after the appointment of a successor entity, the Servicer shall prepare, execute and deliver to the successor entity any and all documents and other instruments, place in such successor’s possession all Servicing Files, and do or cause to be done all other acts or things necessary or appropriate to effect the purposes of such notice of termination, including but not limited to the transfer and endorsement of the Mortgage Notes and related documents, and the preparation and recordation of Assignments of Mortgage. The Servicer shall cooperate with the Master Servicer or the Seller, as applicable, and such successor in effecting the termination of the Servicer’s responsibilities and rights hereunder and the transfer of servicing responsibilities to the successor servicer, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by the Servicer to the Custodial Account or Escrow Account or thereafter received with respect to the Securitized Loans.

Any successor servicer appointed as provided herein shall execute, acknowledge and deliver to the Trustee, the Servicer, the Master Servicer, Certificate Insurer and the Seller an instrument (i) accepting such appointment, wherein the successor shall make the representations and warranties set forth in Section 6.01 (including a representation that the successor servicer is a member of MERS, unless none of the Securitized Loans are MERS Securitized Loans or MERS Eligible Securitized Loans or any such Securitized Loans have been withdrawn from MERS and Assignments of Mortgage are recorded in favor of the Trust) and provide for the same remedies set forth in Section 6.02 and Section 6.03 herein (ii) an assumption of the due and punctual performance and observance of each covenant and condition to be performed and observed by the Servicer under this Agreement, whereupon such successor servicer shall become fully vested with all the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer, with like effect as if originally named as a party to this Agreement. Any termination or resignation of the Servicer or termination of this Agreement pursuant to Sections 6.02, 7.03, 8.01 or 8.02 shall not affect any claims that the Seller, the Depositor, the Master Servicer, Certificate Insurer or the Trustee may have against the Servicer arising out of the Servicer’s actions or failure to act prior to any such termination or resignation. In addition, in the event any successor servicer is appointed pursuant to Section 8.03 of this Agreement, such successor servicer must satisfy the conditions relating to the transfer of servicing set forth in the Trust Agreement.

The Servicer shall deliver promptly to the successor servicer the funds in the Custodial Account and Escrow Account and all Securitized Loan documents and related documents and statements held by it hereunder and the Servicer shall account for all funds and shall execute and deliver such instruments and do such other things as may reasonably be required to more fully and definitively vest in the successor all such rights, powers, duties, responsibilities, obligations and liabilities of the Servicer.

Upon a successor’s acceptance of appointment as such, the Servicer shall notify the Trustee, the Master Servicer, Certificate Insurer, the Seller and the Depositor of such appointment in accordance with the procedures set forth in Section 9.03.

Section 9.02

Costs.

The Seller shall pay any legal fees and expenses of its attorneys. Costs and expenses incurred in connection with the transfer of the servicing responsibilities pursuant to Section 9.01 or pursuant to any other provision of this Agreement, including fees and expenses for delivering Servicing Files, shall be paid by the Seller. Subject to Sections 2.03 and 3.01(a), the Seller shall pay the costs associated with the preparation, delivery and recording of Assignments of Mortgages.

Any part, provision, representation or warranty of this Agreement which is prohibited or unenforceable or is held to be void or unenforceable in any jurisdiction shall be ineffective, as to such jurisdiction, to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction as to any Securitized Loan shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereto waive any provision of law which prohibits or renders void or unenforceable any provision hereof. If the invalidity of any part, provision, representation or warranty of this Agreement shall deprive any party of the economic benefit intended to be conferred by this Agreement, the parties shall negotiate, in good-faith, to develop a structure the economic effect of which is as close as possible to the economic effect of this Agreement without regard to such invalidity.

Section 9.05

No Personal Solicitation.

Section 10.01

Intent of the Parties; Reasonableness.

The Servicer and the Master Servicer acknowledge and agree that the purpose of Article X of this Agreement is to facilitate compliance by the Seller, the Master Servicer and any Depositor with the provisions of Regulation AB and related rules and regulations of the Commission. Although Regulation AB is applicable by its terms only to offerings of asset-backed securities that are registered under the Securities Act, the Servicer acknowledges that investors in privately offered securities may require that the Servicer or any Depositor provide comparable disclosure in unregistered offerings. References in this Agreement to compliance with Regulation AB include provision of comparable disclosure in private offerings.

Neither the Seller, the Master Servicer nor any Depositor shall exercise its right to request delivery of information or other performance under these provisions other than in good faith, or for purposes other than compliance with the Securities Act, the Exchange Act and, in each case, the rules and regulations of the Commission thereunder (or the provision in a private offering of disclosure comparable to that required under the Securities Act) and the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. The Servicer acknowledges that interpretations of the requirements of Regulation AB may change over time, whether due to interpretive guidance provided by the Commission or its staff, consensus among participants in the asset-backed securities markets, advice of counsel, or otherwise, and agrees to comply with requests made by the Seller, the Master Servicer or any Depositor in good faith for delivery of information under these provisions on the basis of established and evolving interpretations of Regulation AB. In connection with any Pass-Through Transfer, the Servicer shall cooperate fully with the Seller and the Master Servicer to deliver to the Seller (including any of its assignees or designees), the Master Servicer and any Depositor, any and all statements, reports, certifications, records and any other information necessary in the good faith determination of the Seller, the Master Servicer or any Depositor to permit the Seller, the Master Servicer or such Depositor to comply with the provisions of Regulation AB, together with such disclosures relating to the Servicer, any Subservicer, or the servicing of the Securitized Loans, reasonably believed by the Seller, the Master Servicer or any Depositor to be necessary in order to effect such compliance.

The Seller (including any of its assignees or designees) and the Master Servicer shall cooperate with the Servicer by providing timely notice of requests for information under these provisions and by reasonably limiting such requests to information required, in the Servicer’s or Master Servicer’s reasonable judgment, to comply with Regulation AB.

(i)(A)

any untrue statement of a material fact contained or alleged to be contained in any information, report, certification, data, accountants’ letter or other material provided in written or electronic form under this Article X by or on behalf of the Servicer, or provided under this Article X by or on behalf of any Subservicer or Subcontractor (collectively, the “Servicer Information”), or (B) the omission or alleged omission to state in the Servicer Information a material fact required to be stated in the Servicer Information or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, by way of clarification, that clause (B) of this paragraph shall be construed solely by reference to the Servicer Information and not to any other information communicated in connection with a sale or purchase of securities, without regard to whether the Servicer Information or any portion thereof is presented together with or separately from such other information;

(ii)

any breach by the Servicer of its obligations under this Article X, including particularly any failure by the Servicer, any Subservicer or any Subcontractor to deliver any information, report, certification, accountants’ letter or other material when and as required under this Article X, including any failure by the Servicer to identify pursuant to Section 10.06(b) any Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB;

(iv)

the negligence, bad faith or willful misconduct of the Servicer in connection with its performance under this Article X.

If the indemnification provided for herein is unavailable or insufficient to hold harmless an Indemnified Party, then the Servicer agrees that it shall contribute to the amount paid or payable by such Indemnified Party as a result of any claims, losses, damages or liabilities incurred by such Indemnified Party in such proportion as is appropriate to reflect the relative fault of such Indemnified Party on the one hand and the Servicer on the other.

In the case of any failure of performance described in clause (a)(ii) of this Section, the Servicer shall promptly reimburse the Seller, the Master Servicer, any Depositor, as applicable, and each Person responsible for the preparation, execution or filing of any report required to be filed with the Commission with respect to such Pass-Through Transfer, or for execution of a certification pursuant to Rule 13a-14(d) or Rule 15d-14(d) under the Exchange Act with respect to such Pass-Through Transfer, for all costs reasonably incurred by each such party in order to obtain the information, report, certification, accountants’ letter or other material not delivered as required by the Servicer, any Subservicer or any Subcontractor.

This indemnification shall survive the termination of this Agreement or the termination of any party to this Agreement.

(b)

(i)

Any failure by the Servicer, any Subservicer or any Subcontractor to deliver any information, report, certification, accountants’ letter or other material when and as required under this Article X, or any breach by the Servicer of a representation or warranty set forth in Section 10.02(a) or in a writing furnished pursuant to Section 10.02(b) and made as of a date prior to the closing date of the related Pass-Through Transfer, to the extent that such breach is not cured by such closing date, or any breach by the Servicer of a representation or warranty in a writing furnished pursuant to Section 10.02(b) to the extent made as of a date subsequent to such closing date, shall, except as provided in clause (ii) of this paragraph, immediately and automatically, without notice or grace period, constitute an Event of Default with respect to the Servicer under this Agreement, and shall entitle the Seller, the Master Servicer or Depositor, as applicable, in its sole discretion to terminate the rights and obligations of the Servicer as servicer under this Agreement without payment (notwithstanding anything in this Agreement to the contrary) of any compensation to the Servicer and if the Servicer is servicing any of the Mortgage Loans in a Pass-Through Transfer, appoint a successor servicer reasonably acceptable to any Master Servicer for such Pass-Through Transfer; provided that to the extent that any provision of this Agreement expressly provides for the survival of certain rights or obligations following termination of the Servicer as servicer, such provision shall be given effect.

(ii)

Any failure by the Servicer, any Subservicer or any Subcontractor to deliver any information, report, certification or accountants’ letter when and as required under Section 10.04 or 10.05, including (except as provided below) any failure by the Servicer to identify pursuant to Section 10.06(b) any Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB, which continues unremedied for ten calendar days after the date on which such information, report, certification or accountants’ letter was required to be delivered shall constitute an Event of Default with respect to the Servicer under this Agreement and any applicable Reconstitution Agreement, and shall entitle the Seller, the Master Servicer or Depositor, as applicable, in its sole discretion to terminate the rights and obligations of the Servicer as servicer under this Agreement without payment (notwithstanding anything in this Agreement to the contrary) of any compensation to the Servicer; provided that to the extent that any provision of this Agreement expressly provides for the survival of certain rights or obligations following termination of the Servicer as servicer, such provision shall be given effect.

None of the Seller, the Master Servicer nor any Depositor shall be entitled to terminate the rights and obligations of the Servicer pursuant to this subparagraph (b)(ii) if a failure of the Servicer to identify a Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB was attributable solely to the role or functions of such Subcontractor with respect to mortgage loans other than the Securitized Loans.

(iii)

The Servicer shall promptly reimburse the Seller (or any designee of the Seller), the Master Servicer and any Depositor, as applicable, for all reasonable expenses incurred by the Servicer (or such designee), the Master Servicer or such Depositor, as such are incurred, in connection with the termination of the Servicer as servicer and the transfer of servicing of the Securitized Loans to a successor servicer. The provisions of this paragraph shall not limit whatever rights the Seller, the Master Servicer or any Depositor may have under other provisions of this Agreement or otherwise, whether in equity or at law, such as an action for damages, specific performance or injunctive relief.

IN WITNESS WHEREOF, the parties hereto have caused their names to be signed hereto by their respective officers thereunto duly authorized as of the date first above written.
