This TRUST AGREEMENT (“Trust Agreement”) dated as of May 1, 2006 (the “Agreement”), is by and among STRUCTURED ASSET SECURITIES CORPORATION, a Delaware corporation, as depositor (the “Depositor”), AURORA LOAN SERVICES LLC, as master servicer (the “Master Servicer”), CITIBANK, N.A., a national banking association, as trustee (the “Trustee”), and ▇▇▇▇▇▇▇ FIXED INCOME SERVICES INC., a Colorado corporation, as credit risk manager (the “Credit Risk Manager”).

PRELIMINARY STATEMENT

The Depositor has acquired the Mortgage Loans from the Seller, and at the Closing Date is the owner of the Mortgage Loans and the other property being conveyed by it to the Trustee hereunder for inclusion in the Trust Fund. On the Closing Date, the Depositor will acquire the Certificates from the Trust Fund as consideration for its transfer to the Trust Fund of the Mortgage Loans and the other property constituting the Trust Fund. The Depositor has duly authorized the execution and delivery of this Agreement to provide for the conveyance to the Trustee of the Mortgage Loans and the other property constituting the Trust Fund. All covenants and agreements made by the Seller in the Mortgage Loan Sale Agreement and by the Depositor, the Master Servicer and the Trustee herein with respect to the Mortgage Loans and the other property constituting the Trust Fund are for the benefit of the Holders from time to time of the Certificates and, to the extent provided herein, the Swap Counterparty. The Depositor, the Trustee, the Master Servicer and the Credit Risk Manager are entering into this Agreement, and the Trustee is accepting the Trust Fund created hereby, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.

As provided herein, an election shall be made that the Trust Fund (exclusive of (i) the Swap Agreement, (ii) the Supplemental Interest Trust Account, (iii) the right to receive and the obligation to pay Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls, (iv) the Basis Risk Reserve Fund, (v), the Supplemental Interest Trust and (vi) the obligation to pay Class I Shortfalls (collectively, the “Excluded Trust Assets”)) be treated for federal income tax purposes as comprising five real estate mortgage investment conduits under Section 860D of the Code (each a “REMIC” or, in the alternative “REMIC 1,” “REMIC 2,” “REMIC 3,” “REMIC 4” and “REMIC 5.” Any inconsistencies or ambiguities in this Agreement or in the administration of this Agreement shall be resolved in a manner that preserves the validity of such REMIC elections.

Each Certificate, other than the Class R, Class LT-R, and Class X Certificates, represents ownership of a regular interest in REMIC 5 for purposes of the REMIC Provisions. In addition, each Certificate, other than the Class R, Class LT-R, Class X and Class P Certificates, represents (i) the right to receive payments with respect to any Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls and (ii) the obligation to pay Class I Shortfalls. The Class LT-R Certificate represents ownership of the sole Class of residual interest in REMIC 1. The Class R Certificate represents ownership of the sole Class of residual interest in each of REMIC 2, REMIC 3, REMIC 4 and REMIC 5.

REMIC 5 shall hold as assets the uncertificated Lower Tier Interests in REMIC 4, other than the Class LT4-R interest, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 4. REMIC 4 shall hold as its assets the uncertificated Lower Tier Interests in REMIC 3, other than the Class LT3-R interest, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 3. REMIC 3 shall hold as its assets the uncertificated Lower Tier Interests in REMIC 2, other than the Class LT2-R interest, and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 2. REMIC 2 shall hold as its assets the uncertificated Lower Tier Interests in REMIC 1 and each such Lower Tier Interest is hereby designated as a regular interest in REMIC 1. REMIC 1 shall hold as its assets the property of the Trust Fund other than the Lower Tier Interests in REMIC 1, REMIC 2, REMIC 3, REMIC 4 and REMIC 5 and the Excluded Trust Assets.

The startup day for each REMIC created hereby for purposes of the REMIC Provisions is the Closing Date. In addition, for purposes of the REMIC Provisions, the latest possible maturity date for each regular interest in each REMIC created hereby is the Latest Possible Maturity Date.

REMIC 1:

REMIC 1 shall issue one uncertificated interest in respect of each Mortgage Loan held by the Trust Fund on the Closing Date, each of which is hereby designated as a regular interest in REMIC 1 (the “REMIC 1 Regular Interests”). REMIC 1 shall also issue the Class LT-R Certificate, which shall represent the sole class of residual interest in REMIC 1. Each REMIC 1 Regular Interest shall have an initial principal balance equal to the Scheduled Principal Balance of the Mortgage Loan to which it relates and shall bear interest at a per annum rate equal to the Net Mortgage Rate of such Mortgage Loan. In the event a Qualified Substitute Mortgage Loan is substituted for such Mortgage Loan (the “Original Mortgage Loan”), no amount of interest payable on such Qualified Substitute Mortgage Loan shall be distributed on such REMIC 1 Regular Interest at a rate in excess of the Net Mortgage Rate of the Original Mortgage Loan.

On each Distribution Date, the Trustee shall first pay or charge as an expense of REMIC 1 all expenses of the Trust Fund for such Distribution Date, other than any expenses in respect of the Swap Agreement.

On each Distribution Date the Trustee shall distribute the aggregate Interest Remittance Amount (net of expenses described in the preceding paragraph) with respect to each of the Lower Tier Interests in REMIC 1 based on the above-described interest rates.

On each Distribution Date, the Trustee shall distribute the aggregate Principal Remittance Amount among the Lower Tier Interests in REMIC 1 in accordance with the amount of the Principal Remittance Amount attributable to the Mortgage Loan corresponding to each such Lower Tier Interest in REMIC 1. All losses on the Mortgage Loans shall be allocated among the Lower Tier Interests in REMIC 1 in the same manner that principal distributions are allocated.

On each Distribution Date, the Trustee shall distribute the Prepayment Premiums collected during the preceding Prepayment Period, in the case of Principal Prepayments in full, or during the related Collection Period, in the case of Principal Prepayments in part, to the Lower Tier Interest in REMIC 1 corresponding to the Mortgage Loan with respect to which such amounts were received.

(1)

For any Distribution Date (and the related Accrual Period) the interest rate for the LT3-A Interest is a per annum rate equal to the weighted average of the interest rates on the Lower Tier Interests in REMIC 2 for such Distribution Date, provided, however, that for any Distribution Date on which the Class LT3-SIO Interest is entitled to a portion of the interest accruals on a Lower Tier Interest in REMIC 2 having an “F” in its class designation, as described in footnote four below, such weighted average shall be computed by first subjecting the rate on such Lower Tier Interest in REMIC 2 to a cap equal to Swap LIBOR for such Distribution Date.

(2) For any Distribution Date (and the related Accrual Period) the interest rate for each of these REMIC 3 Regular Interests shall be a per annum rate equal to the lesser of (i) 9.00% and (ii) the product of (a) 2 multiplied by (b) the weighted average of the interest rates on the REMIC 2 Regular Interests for such Distribution Date, provided, however, that for any Distribution Date on which the Class LT3-SIO Interest is entitled to a portion of the interest accruals on a REMIC 2 Regular Interest having an “F” in its class designation, as described in footnote four below, such weighted average shall be computed by first subjecting the rate on such REMIC 2 Regular Interest to a cap equal to Swap LIBOR for such Distribution Date.

(3) For any Distribution Date (and the related Accrual Period) the interest rate for each of these REMIC 2 Regular Interests shall be a per annum rate equal to the excess, if any, of (i) the product of (a) 2 multiplied by (b) the weighted average of the interest rates on the REMIC 2 Regular Interests for such Distribution Date, provided, however, that for any Distribution Date on which the Class LT3-SIO Interest is entitled to a portion of the interest accruals on a REMIC 2 Regular Interest having an “F” in its class designation, as described in footnote four below, such weighted average shall be computed by first subjecting the rate on such REMIC 2 Regular Interest to a cap equal to Swap LIBOR for such Distribution Date, over (ii) 9.00%.

(4)

The Class LT3-SIO is an interest only class that does not have a principal balance. For only those Distribution Dates listed in the first column in the table below, the Class LT3-IO shall be entitled to interest accrued on the Lower Tier Interest in REMIC 2 listed in the second column in the table below at a per annum rate equal to the excess, if any, of (i) the interest rate for such Lower Tier Interest in REMIC 2 for such Distribution Date over (ii) Swap LIBOR for such Distribution Date.

(5) The Class LT3-R interest is the sole class of residual interests in REMIC 3. It does not have an interest rate or a principal balance.

On each Distribution Date, interest distributable in respect of the Lower Tier Interests in REMIC 2 for such Distribution Date shall be distributed to the Lower Tier Interests in REMIC 3 at the rates shown above.

On each Distribution Date, all Realized Losses and all payments of principal in respect of the REMIC 2 Regular Interests shall be allocated first to the LT3-A Interest until the Class Principal Amount of such Interest is reduced to zero, and then sequentially to the other REMIC 3 Regular Interest in ascending order of their numerical class designation, and, with respect to each pair of classes having the same numerical designation, in equal amounts to each such class, until the Class Principal Amount of each such class is reduced to zero.

On each Distribution Date, the Trustee shall distribute the Prepayment Premiums collected during the preceding Prepayment Period to the LT3-F5 Interest.

(1) This interest rate with respect to any Distribution Date (and the related Accrual Period) for each of these REMIC 3 Regular Interests is a per annum rate equal to the greater of (i) 0.00% and (ii) the weighted average of the interest rates on each REMIC 2 Interest having an “A-IO” in its designation and the LT2-Pool Interest, computed after reducing the rate payable on each such REMIC 2 Interest having an “A-IO” in its Class designation by 1.50% for any Distribution Date on which interest is payable on its Corresponding REMIC 3 A-IO Interest (as described in footnote (3) below).

(2)

This interest shall have an initial principal balance equal to the excess of (a) the aggregate Principal Balance of the Mortgage Loans as of the Cut-off Date over (b) the sum of the initial principal balances of the interests in REMIC 3 (other than any interest-only classes).

(3)

The Class LT4-AIO is an interest only class that does not have a principal balance. For only those Distribution Dates listed in the first column in the table below, the Class LT4-AIO shall be entitled to 100% of the interest accrued on the Lower Tier Interest in REMIC 3 listed in the second column in the table below.

Distribution Dates	Corresponding REMIC 3 Regular Interest
1-3	LT3-F1
1-6	LT3-F2
1-9	LT3-F3
1-12	LT3-F4
1-15	LT3-F5

The LT4-SIO Interest shall not have a principal balance, but shall be entitled to receive, on each Distribution Date, 100% of the interest distributable on the Class LT3-SIO Interest in REMIC 3.

(5)

The LT4-R interest shall not have a principal amount and shall not bear interest. The LT4-R interest is hereby designated as the sole class of residual interest in REMIC 4.

On each Distribution Date, interest distributable in respect of the REMIC 3 Regular Interests shall be distributed with respect to each of the REMIC 4 Regular Interests based on the above-described interest rates, provided, however, that interest that accrues on the LT4-Q Interest shall be deferred to the extent necessary to make the principal distributions described in priority (i) below for such Distribution Date. Any interest so deferred shall itself bear interest at the interest rate for the LT4-Q Interest.

On each Distribution Date, the principal distributed on the REMIC 3 Regular Interests (together with an amount equal to the interest deferred on the Class LT4-Q Interest for such Distribution Date) shall be distributed, and Realized Losses shall be allocated, among the REMIC 3 Regular Interests in the following order of priority:

(i)

first, to each REMIC 4 Regular Interest having a Corresponding Class in REMIC 5 (other than the LT4-AIO and LT4-SIO Interests) until the Class Principal Amount of each such REMIC 4 Regular Interest equals one-half of the Class Principal Amount of the Corresponding Class of Certificates immediately after such Distribution Date;

(ii)

second, to the Class LT4-Q Interest, any remaining amounts.

On each Distribution Date, the Trustee shall distribute the Prepayment Premiums collected during the preceding Prepayment Period to the LT4-Q Interest.

(1)

The Certificate Interest Rate with respect to any Distribution Date (and the related Accrual Period) for the Class A1 Certificates is the per annum rate equal to the lesser of (i) LIBOR plus 0.070% and (ii) the Net Funds Cap for such Distribution Date; provided that if the Mortgage Loans and related property are not purchased pursuant to Section 7.01(b) on the Initial Optional Termination Date, then with respect to each subsequent Distribution Date the per annum rate calculated pursuant to clause (i) above with respect to the Class A1 Certificates will be LIBOR plus 0.140%. For purposes of the REMIC Provisions, the reference to “Net Funds Cap” in clause (ii) of the preceding sentence shall be deemed to be a reference to the REMIC 4 Net Funds Cap. For any Distribution Date on which the Certificate Interest Rate for this Certificate is based on the Net Funds Cap, the amount of interest that would have payable on such Certificates if the REMIC 4 Net Funds Cap were substituted for the Net Funds Cap over the amount actually payable thereon shall be treated as having been paid to the owners of the Class A1 Certificates and then deposited by such owners into the Supplemental Interest Trust pursuant to Section 10.01(n) hereof.

(2)

The Certificate Interest Rate with respect to any Distribution Date (and the related Accrual Period) for the Class A2 Certificates is the per annum rate equal to the lesser of (i) 5.500% and (ii) the Net Funds Cap for such Distribution Date; provided that if the Mortgage Loans and related property are not purchased pursuant to Section 7.01(b) on the Initial Optional Termination Date, then with respect to each subsequent Distribution Date the per annum rate calculated pursuant to clause (i) above with respect to the Class A2 Certificates will be 6.000%. For purposes of the REMIC Provisions, the reference to “Net Funds Cap” in clause (ii) of the preceding sentence shall be deemed to be a reference to the REMIC 4 Net Funds Cap. For any Distribution Date on which the Certificate Interest Rate for this Certificate is based on the Net Funds Cap, the amount of interest that would have payable on such Certificates if the REMIC 4 Net Funds Cap were substituted for the Net Funds Cap over the amount actually payable thereon shall be treated as having been paid to the owners of the Class A2 Certificates and then deposited by such owners into the Supplemental Interest Trust pursuant to Section 10.01(n) hereof.

(3)

The Certificate Interest Rate with respect to any Distribution Date (and the related Accrual Period) for the Class A-IO Certificates is a per annum rate equal to the lesser of (i) 9.000% and (ii) the Class A-IO Net Funds Cap. For purposes of the REMIC Provisions, the reference to the Class A-IO Net Funds Cap in clause (ii) of the preceding sentence shall be deemed a reference to the REMIC 4 A-IO Net Funds Cap; therefore, on any Distribution Date on which the Certificate Interest Rate on the Class A-IO Certificates is based on the Class A-IO Net Funds Cap, the amount of interest that would have accrued on the Class A-IO Certificates if the REMIC 4 A-IO Net Funds Cap were substituted for the Class A-IO Net Funds Cap shall be treated as having been paid to the owners of the Class A-IO Certificates and then deposited by such owners in the Supplemental Interest Trust, pursuant to Section 10.01(n) hereof. The Class A-IO Certificates will not bear interest after the Distribution Date in August 2007.

The Class A-IO Certificates do not have a Class Principal Amount but shall accrue interest on their Class Notional Amount.

(5)

The Certificate Interest Rate with respect to any Distribution Date (and the related Accrual Period) for the Class M1 Certificates is the per annum rate equal to the lesser of (i) LIBOR plus 0.280% and (ii) the Net Funds Cap for such Distribution Date; provided that if the Mortgage Loans and related property are not purchased pursuant to Section 7.01(b) on the Initial Optional Termination Date, then with respect to each subsequent Distribution Date the per annum rate calculated pursuant to clause (i) above with respect to the Class M1 Certificates will be LIBOR plus 0.420%. For purposes of the REMIC Provisions, the reference to “Net Funds Cap” in clause (ii) of the preceding sentence shall be deemed to be a reference to the REMIC 4 Net Funds Cap. For any Distribution Date on which the Certificate Interest Rate for this Certificate is based on the Net Funds Cap, the amount of interest that would have payable on such Certificates if the REMIC 4 Net Funds Cap were substituted for the Net Funds Cap over the amount actually payable thereon shall be treated as having been paid to the owners of the Class M1 Certificates and then deposited by such owners into the Supplemental Interest Trust pursuant to Section 10.01(n) hereof.

(6)

The Certificate Interest Rate with respect to any Distribution Date (and the related Accrual Period) for the Class M2 Certificates is the per annum rate equal to the lesser of (i) 6.000% and (ii) the Net Funds Cap for such Distribution Date; provided that if the Mortgage Loans and related property are not purchased pursuant to Section 7.01(b) on the Initial Optional Termination Date, then with respect to each subsequent Distribution Date the per annum rate calculated pursuant to clause (i) above with respect to the Class M2 Certificates will be 6.500%. In addition, on each Distribution Date, the Class M2 Certificates shall be entitled to distributions of any M2 Excess Amount for such Distribution Date. For purposes of the REMIC Provisions, the Class M2 Certificates comprise four components. One component represents the rights to all distributions in reduction of the Class Principal Amount of the Class M2 Certificates and all distributions of interest thereon at the Certificate Interest Rate for the Class M2 Certificates. The Class M2 Certificates also have a principal only component and two interest only components. The principal only component has an initial principal balance of $9,843,317.26 (initial Overcollateralization Amount of $9,843,417.26 less $100.00 allocated to create the Class P Principal Amount). One interest only component has a notional principal balance that will at all times equal the aggregate of the Class Principal Amounts of the REMIC 4 Regular Interests (other than the LT4-AIO and LT4-SIO Interests) and this notional component shall accrue interest for each Accrual Period at a per annum rate equal to the excess, if any, of (i) the difference between (a) weighted average of the interest rates on the REMIC 4 Regular Interests (other than the LT4-AIO and LT4-SIO Interests) weighted on the basis of their Class Principal Amounts as of the first day of the Accrual Period minus (b) the Credit Manager’s Fee Rate, over (ii) the Adjusted REMIC 4 WAC. The second notional component represents the right to receive 100% of the distributions in respect of the Class LT4-SIO Interest.

(7)

The Certificate Interest Rate with respect to any Distribution Date (and the related Accrual Period) for the Class M3 Certificates is the per annum rate equal to the lesser of (i) LIBOR plus 0.330% and (ii) the Net Funds Cap for such Distribution Date; provided that if the Mortgage Loans and related property are not purchased pursuant to Section 7.01(b) on the Initial Optional Termination Date, then with respect to each subsequent Distribution Date the per annum rate calculated pursuant to clause (i) above with respect to the Class M3 Certificates will be LIBOR plus 0.495%. For purposes of the REMIC Provisions, the reference to “Net Funds Cap” in clause (ii) of the preceding sentence shall be deemed to be a reference to the REMIC 4 Net Funds Cap. For any Distribution Date on which the Certificate Interest Rate for this Certificate is based on the Net Funds Cap, the amount of interest that would have payable on such Certificates if the REMIC 4 Net Funds Cap were substituted for the Net Funds Cap over the amount actually payable thereon shall be treated as having been paid to the owners of the Class M3 Certificates and then deposited by such owners into the Supplemental Interest Trust pursuant to Section 10.01(n) hereof.

(8)

The Certificate Interest Rate with respect to any Distribution Date (and the related Accrual Period) for the Class M4 Certificates is the per annum rate equal to the lesser of (i) LIBOR plus 0.350% and (ii) the Net Funds Cap for such Distribution Date; provided that if the Mortgage Loans and related property are not purchased pursuant to Section 7.01(b) on the Initial Optional Termination Date, then with respect to each subsequent Distribution Date the per annum rate calculated pursuant to clause (i) above with respect to the Class M4 Certificates will be LIBOR plus 0.525%. For purposes of the REMIC Provisions, the reference to “Net Funds Cap” in clause (ii) of the preceding sentence shall be deemed to be a reference to the REMIC 4 Net Funds Cap. For any Distribution Date on which the Certificate Interest Rate for this Certificate is based on the Net Funds Cap, the amount of interest that would have payable on such Certificates if the REMIC 4 Net Funds Cap were substituted for the Net Funds Cap over the amount actually payable thereon shall be treated as having been paid to the owners of the Class M4 Certificates and then deposited by such owners into the Supplemental Interest Trust pursuant to Section 10.01(n) hereof.

The Seller, the Master Servicer, the Depositor, the Servicer and the Certificateholders (by their acceptance of such Certificates) acknowledge and agree that the Trustee is executing and delivering the Swap Agreement solely in its capacity as Trustee of the Supplemental Interest Trust and not in its individual capacity. The Depositor hereby authorizes and directs the Trustee to enter into the Swap Agreement and authorizes it to represent in the Swap Agreement that it is not required by any applicable law of any relevant jurisdiction to make any deduction or withholding for or on account of any tax from any Net Swap Payment. The Trustee shall have no duty or responsibility to enter into any other interest rate swap agreement upon the expiration or termination of the Swap Agreement.

Concurrently with the execution and delivery of this Agreement, the Depositor does hereby assign to the Trustee all of its rights and interest under the Mortgage Loan Sale Agreement, including all rights of the Seller under each Servicing Agreement and each Transfer Agreement (including the right to enforce the Transferor’s obligation pursuant to the PPTLS) but only to the extent assigned under the Mortgage Loan Sale Agreement. The Trustee hereby accepts such assignment, and shall be entitled to exercise all the rights of the Depositor under the Mortgage Loan Sale Agreement as if, for such purpose, it were the Depositor.

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

(a)

The Trustee, by execution and delivery hereof, acknowledges receipt by it or by the applicable Custodian on its behalf of the Mortgage Files pertaining to the Mortgage Loans listed on the Mortgage Loan Schedule, subject to review thereof by the Trustee, or by the applicable Custodian on behalf of the Trustee, under this Section 2.02. The Trustee, or the applicable Custodian on behalf of the Trustee, will execute and deliver to the Depositor, the Master Servicer and the Trustee on the Closing Date an Initial Certification in the form annexed hereto as Exhibit B-1 (or in the form annexed to the applicable Custodial Agreement as Exhibit B-1, as applicable).

(b)

Within 45 days after the Closing Date, the Trustee or the applicable Custodian on behalf of the Trustee, will, for the benefit of Holders of the Certificates, review each Mortgage File to ascertain that all required documents set forth in Section 2.01 have been received and appear on their face to contain the requisite signatures by or on behalf of the respective parties thereto, and shall deliver to the Trustee, the Depositor and the Master Servicer an Interim Certification in the form annexed hereto as Exhibit B-2 (or in the form annexed to the applicable Custodial Agreement as Exhibit B-2, as applicable) to the effect that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan prepaid in full or any Mortgage Loan specifically identified in such certification as not covered by such certification), (i) all of the applicable documents specified in Section 2.01(b) are in its possession and (ii) such documents have been reviewed by it and appear to relate to such Mortgage Loan. The Trustee, or the applicable Custodian on behalf of the Trustee, shall determine whether such documents are executed and endorsed, but shall be under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine that the same are valid, binding, legally effective, properly endorsed, genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded or are in recordable form or that they are other than what they purport to be on their face. Neither the Trustee nor any applicable Custodian shall have any responsibility for verifying the genuineness or the legal effectiveness of or authority for any signatures of or on behalf of any party or endorser.

(c)

If in the course of the review described in paragraph (b) above the Trustee or the applicable Custodian discovers any document or documents constituting a part of a Mortgage File that is missing, does not appear regular on its face (i.e., is mutilated, damaged, defaced, torn or otherwise physically altered) or appears to be unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule (each, a “Material Defect”), the Trustee, or the applicable Custodian on behalf of the Trustee, discovering such Material Defect shall promptly identify the Mortgage Loan to which such Material Defect relates in the Interim Certification delivered to the Trustee, the Depositor and the Master Servicer.

If the applicable Transferor or the Depositor, as applicable, does not so cure such Material Defect, the Transferor, or, if the Transferor does not do so, the Depositor, shall, if a loss has been incurred with respect to such Mortgage Loan that would, if such Mortgage Loan were not purchased from the Trust Fund, constitute a Realized Loss, and such loss is attributable to the failure of the Depositor to cure such Material Defect, repurchase the related Mortgage Loan from the Trust Fund at the Purchase Price. A loss shall be deemed to be attributable to the failure of the Depositor to cure a Material Defect if, as determined by the Depositor, upon mutual agreement with the Trustee each acting in good faith, absent such Material Defect, such loss would not have been incurred. Within the two-year period following the Closing Date, the Depositor may, in lieu of repurchasing a Mortgage Loan pursuant to this Section 2.02, substitute for such Mortgage Loan a Qualifying Substitute Mortgage Loan subject to the provisions of Section 2.05. The failure of the Trustee or the applicable Custodian to give the notice contemplated herein within 45 days after the Closing Date shall not affect or relieve the Depositor of its obligation to repurchase any Mortgage Loan pursuant to this Section 2.02 or any other Section of this Agreement requiring the repurchase of Mortgage Loans from the Trust Fund.

immediately prior to the transfer and assignment of the Mortgage Loans to the Trustee, the Depositor was the sole owner of record and holder of each Mortgage Loan, and the Depositor had good and marketable title thereto, and had full right to transfer and sell each Mortgage Loan to the Trustee free and clear, subject only to (1) any senior lien mortgage on the related Mortgaged Property, (2) liens of current real property taxes and assessments not yet due and payable and, if the related Mortgaged Property is a condominium unit, any lien for common charges permitted by statute, (3) covenants, conditions and restrictions, rights of way, easements and other matters of public record as of the date of recording of such Mortgage acceptable to mortgage lending institutions in the area in which the related Mortgaged Property is located and specifically referred to in the lender’s Title Insurance Policy or attorney’s opinion of title and abstract of title delivered to the originator of such Mortgage Loan, and (4) such other matters to which like properties are commonly subject which do not, individually or in the aggregate, materially interfere with the benefits of the security intended to be provided by the Mortgage, of any encumbrance, equity, participation interest, lien, pledge, charge, claim or security interest, and had full right and authority, subject to no interest or participation of, or agreement with, any other party, to sell and assign each Mortgage Loan pursuant to this Agreement.

(b)

The representations and warranties of each Transferor with respect to the related Mortgage Loans in the applicable Transfer Agreement, which have been assigned to the Trustee hereunder, were made as of the date specified in the applicable Transfer Agreement (or underlying agreement, if such Transfer Agreement is in the form of an assignment of a prior agreement). To the extent that any fact, condition or event with respect to a Mortgage Loan constitutes a breach of both (i) a representation or warranty of the applicable Transferor under the applicable Transfer Agreement and (ii) a representation or warranty of the Seller under the Mortgage Loan Sale Agreement, the only right or remedy of the Trustee or any Certificateholder hereunder shall be their rights to enforce the obligations of the applicable Transferor under any applicable representation or warranty made by it. Except as otherwise provided in the Mortgage Loan Sale Agreement, the Seller shall not have any other obligation or liability with respect to any breach of a representation or warranty made by it with respect to the Mortgage Loans sold by it if the fact, condition or event constituting such breach also constitutes a breach of a representation or warranty made by the applicable Transferor in the applicable Transfer Agreement, without regard to whether such Transferor fulfills its contractual obligations in respect of such representation or warranty. The Depositor shall have no obligation or liability with respect to any breach of any representation or warranty with respect to the Mortgage Loans (except as set forth in Section 2.03(a)(vi)) under any circumstances.

Section 2.04

Discovery of Breach.

It is understood and agreed that the representations and warranties (i) of the Depositor set forth in Section 2.03, (ii) of the Seller set forth in the Mortgage Loan Sale Agreement and assigned to the Depositor by the Seller under the Mortgage Loan Sale Agreement and to the Trustee by the Depositor hereunder and (iii) of each Transferor and of the Servicer assigned by the Seller to the Depositor pursuant to the Mortgage Loan Sale Agreement and assigned to the Trustee by the Depositor hereunder, shall each survive delivery of the Mortgage Files and the Assignment of Mortgage of each Mortgage Loan to the Trustee and shall continue throughout the term of this Agreement. Upon discovery by any of the Depositor, the Master Servicer or the Trustee of a breach of any of such representations and warranties that adversely and materially affects the value of the related Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties. Within 90 days of the discovery of a breach of any representation or warranty given to the Trustee by the Depositor or given by any Transferor or the Seller and assigned to the Trustee, the Depositor, such Transferor or the Seller, as applicable, shall (a) cure such breach in all material respects, (b) repurchase such Mortgage Loan or any property acquired in respect thereof from the Trustee at the Purchase Price, or (c) within the two-year period following the Closing Date, substitute a Qualifying Substitute Mortgage Loan for the affected Mortgage Loan. In the event of discovery of a breach of any representation and warranty of any Transferor assigned to the Trustee, the Trustee shall enforce its rights under the applicable Transfer Agreement and the Mortgage Loan Sale Agreement for the benefit of Certificateholders. As provided in the Mortgage Loan Sale Agreement, if the Transferor substitutes a mortgage loan for a Deleted Mortgage Loan pursuant to the related Transfer Agreement and such substitute mortgage loan is not a Qualifying Substitute Mortgage Loan, then pursuant to the terms of the Mortgage Loan Sale Agreement the Seller will, in exchange for such substitute mortgage loan, (i) pay to the Trust Fund the applicable Purchase Price for the affected Mortgage Loan or (ii) within two years of the Closing Date, substitute a Qualifying Substitute Mortgage Loan.

Section 2.05

Repurchase, Purchase or Substitution of Mortgage Loans.

(a)

With respect to any Mortgage Loan repurchased by the Depositor pursuant to this Agreement, by the Seller pursuant to the Mortgage Loan Sale Agreement or by the Transferor pursuant to the applicable Transfer Agreement, the principal portion of the funds (including the related PPTL Purchase Price in the case of a First Payment Default Mortgage Loan) received by the Trustee in respect of such repurchase of a Mortgage Loan will be considered a Principal Prepayment and the Purchase Price or PPTL Purchase Price shall be deposited in the Collection Account or a Custodial Account, as applicable. The Master Servicer, the Servicer, the Custodian (or the Trustee in its capacity as successor master servicer, if applicable) shall be reimbursed from the Purchase Price for any Mortgage Loan or related REO Property for any Advances made or other amounts advanced with respect to such Mortgage Loan that are reimbursable to the Master Servicer or the Servicer under this Agreement or the Servicing Agreement (or to the Trustee in its capacity as successor master servicer, if applicable), together with any accrued and unpaid compensation due to the Master Servicer, the Servicer, the Custodian or the Trustee hereunder or thereunder. The Trustee (i) upon receipt of the full amount of the Purchase Price for a Deleted Mortgage Loan, (ii) upon receipt of a written certification from the Master Servicer that it has received the full amount of the Purchase Price for a Deleted Mortgage Loan and has deposited such amount in the Collection Account or (iii) upon receipt of notification from the related Custodian that it had received the Mortgage File for a Qualifying Substitute Mortgage Loan substituted for a Deleted Mortgage Loan (and any applicable Substitution Amount), shall release or cause to be released and reassign to the Depositor, the Seller or the Transferor, as applicable, the related Mortgage File for the Deleted Mortgage Loan and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty, as shall be necessary to vest in such party or its designee or assignee title to any Deleted Mortgage Loan released pursuant hereto, free and clear of all security interests, liens and other encumbrances created by this Agreement, which instruments shall be prepared by the related Servicer and the Trustee shall have no further responsibility with respect to the Mortgage File relating to such Deleted Mortgage Loan. The Seller indemnifies and holds the Trust Fund, the Master Servicer, the Trustee and the Depositor and each Certificateholder harmless against any and all taxes, claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, fees and expenses that the Trust Fund, the Trustee, the Master Servicer, the Depositor and any Certificateholder may sustain in connection with any actions of such Seller relating to a repurchase of a Mortgage Loan other than in compliance with the terms of this Section 2.05 and the Mortgage Loan Sale Agreement, to the extent that any such action causes an Adverse REMIC Event.

(b)

With respect to each Qualifying Substitute Mortgage Loan to be delivered to the Trustee (or the applicable Custodian) pursuant to the terms of this Article II in exchange for a Deleted Mortgage Loan: (i) the Depositor, the Transferor or the Seller, as applicable, must deliver to the Trustee (or the applicable Custodian) the Mortgage File for the Qualifying Substitute Mortgage Loan containing the documents set forth in Section 2.01(b) along with a written certification certifying as to the delivery of such Mortgage File and containing granting language substantially comparable to that set forth in the first paragraph of Section 2.01(a); and (ii) the Depositor will be deemed to have made, with respect to such Qualifying Substitute Mortgage Loan, each of the representations and warranties made by it with respect to the related Deleted Mortgage Loan. As soon as practicable after the delivery of any Qualifying Substitute Mortgage Loan hereunder, the Master Servicer, at the expense of the Depositor and at the direction and with the cooperation of the applicable Servicer, shall (i) with respect to a Qualifying Substitute Mortgage Loan that is a Non-MERS Mortgage Loan, cause the Assignment of Mortgage to be recorded by the applicable Servicer if required pursuant to Section 2.01(c), or (ii) with respect to a Qualifying Substitute Mortgage Loan that is a MERS Mortgage Loan, cause to be taken such actions as are necessary to cause the Trustee to be clearly identified as the owner of each such Mortgage Loan on the records of MERS if required pursuant to Section 2.01(c).

(c)

Notwithstanding any other provision of this Agreement, the right to substitute Mortgage Loans pursuant to this Article II shall be subject to the additional limitations that no substitution of a Qualifying Substitute Mortgage Loan for a Deleted Mortgage Loan shall be made unless the Trustee has received an Opinion of Counsel addressed to the Trustee (at the expense of the party seeking to make the substitution) that, under current law, such substitution will not cause an Adverse REMIC Event.

Section 2.06

Grant Clause.

(a)

It is intended that the conveyance of the Depositor’s right, title and interest in and to property constituting the Trust Fund pursuant to this Agreement shall constitute, and shall be construed as, a sale of such property and not a grant of a security interest to secure a loan. However, if such conveyance is deemed to be in respect of a loan, it is intended that: (1) the rights and obligations of the parties shall be established pursuant to the terms of this Agreement; (2) the Depositor hereby grants to the Trustee for the benefit of the Holders of the Certificates a first priority security interest to secure repayment of an obligation in an amount equal to the aggregate Class Principal Amount of the Certificates (or the aggregate principal balance of the Lower Tier REMIC 1 Uncertificated Regular Interests, if applicable) in all of the Depositor’s right, title and interest in, to and under, whether now owned or hereafter acquired, the Trust Fund and the Supplemental Interest Trust and all proceeds of any and all property constituting the Trust Fund and the Supplemental Interest Trust to secure payment of the Certificates or Lower Tier REMIC 1 Uncertificated Regular Interests, as applicable, (such security interest being, to the extent of the assets that constitute the Supplemental Interest Trust, pari passu with the security interest as provided in clause (4) below); (3) this Agreement shall constitute a security agreement under applicable law; and (4) the Swap Counterparty shall be deemed, during the term of such agreement and while such agreement is the property of the Trustee, to have a security interest in all of the assets that constitute the Supplemental Interest Trust, but only to the extent of such Swap Counterparty’s right to payment under the Swap Agreement (such security interest being pari passu with the security interest as provided in clause (2) above). If such conveyance is deemed to be in respect of a loan and the trust created by this Agreement terminates prior to the satisfaction of the claims of any Person holding any Certificate or Lower Tier REMIC 1 Uncertificated Regular Interests, as applicable, the security interest created hereby shall continue in full force and effect and the Trustee shall be deemed to be the collateral agent for the benefit of such Person, and all proceeds shall be distributed as herein provided.

(b)

The Depositor shall, to the extent consistent with this Agreement, take such reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the other property described above, such security interest would be deemed to be a perfected security interest of first priority under applicable law and shall be maintained as such throughout the term of this Agreement. The Depositor shall, at its own expense, make all initial filings on or about the Closing Date and shall forward a copy of such filing or filings to the Trustee. Without limiting the generality of the foregoing, the Depositor shall prepare and forward for filing, or shall cause to be forwarded for filing, at the expense of the Depositor, all filings necessary to maintain the effectiveness of any original filings necessary under the relevant UCC to perfect the Trustee’s security interest in or lien on the Mortgage Loans, including without limitation (x) continuation statements, and (y) such other statements as may be occasioned by (1) any change of name of the Seller, the Depositor or the Trustee, (2) any change of location of the jurisdiction of organization of the Seller or the Depositor, (3) any transfer of any interest of the Seller or the Depositor in any Mortgage Loan or (4) any change under the relevant UCC or other applicable laws. Neither the Seller nor the Depositor shall organize under the law of any jurisdiction other than the State under which each is organized as of the Closing Date (whether changing its jurisdiction of organization or organizing under an additional jurisdiction) without giving 30 days prior written notice of such action to its immediate and intermediate transferee, including the Trustee. Before effecting such change, the Seller or the Depositor proposing to change its jurisdiction of organization shall prepare and file in the appropriate filing office any financing statements or other statements necessary to continue the perfection of the interests of its immediate and intermediate transferees, including the Trustee, in the Mortgage Loans. In connection with the transactions contemplated by this Agreement, each of the Seller and the Depositor authorizes its immediate or intermediate transferee to file in any filing office any initial financing statements, any amendments to financing statements, any continuation statements, or any other statements or filings described in this paragraph (b).

ARTICLE III

THE CERTIFICATES

Section 3.01

The Certificates.

(a)

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

(b)

The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by an authorized officer. Each Certificate shall, on original issue, be authenticated by the Trustee upon the order of the Depositor upon receipt by the Trustee (or its applicable Custodian) of the Mortgage Files described in Section 2.01. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided for herein, executed by an authorized officer of the Trustee or the Authenticating Agent, if any, by manual signature, and such certification upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. At any time and from time to time after the execution and delivery of this Agreement, the Depositor may deliver Certificates executed by the Depositor to the Trustee or the Authenticating Agent for authentication and the Trustee or the Authenticating Agent shall authenticate and deliver such Certificates as in this Agreement provided and not otherwise.

(c)

Any Class M2 Certificate or Class B Certificate offered and sold in reliance on the exemption from registration under Rule 144A under the Securities Act shall be issued initially in the form of one or more permanent global Certificates in definitive, fully registered form without interest coupons with the applicable legends set forth in Exhibit A added to the forms of such Certificates (each, a “Restricted Global Security”), which shall be deposited on behalf of the subscribers for such Certificates represented thereby with the Trustee, as custodian for The Depository Trust Company (“DTC”) and registered in the name of a nominee of DTC, duly executed and authenticated by the Trustee as hereinafter provided. The aggregate principal amounts of the Restricted Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee or DTC or its nominee, as the case may be, as hereinafter provided.

(d)

Any Class M2 Certificate or Class B Certificate sold in offshore transactions in reliance on Regulation S shall be issued initially in the form of one or more permanent global Certificates in definitive, fully registered form without interest coupons with the applicable legends set forth in Exhibit A hereto added to the forms of such Certificates (each, a “Regulation S Global Security”), which shall be deposited on behalf of the subscribers for such Certificates represented thereby with the Trustee, as custodian for DTC and registered in the name of a nominee of DTC, duly executed and authenticated by the Trustee as hereinafter provided. The aggregate principal amounts of the Regulation S Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee or DTC or its nominee, as the case may be, as hereinafter provided.

(e)

Any Class M2 Certificate or Class B Certificate sold to an “accredited investor” under Rule 501(a)(1), (2), (3) or (7) under the Securities Act shall be issued initially in the form of one or more Definitive Certificates.

Section 3.02

Registration.

The Trustee is hereby appointed, and hereby accepts its appointment as, Certificate Registrar in respect of the Certificates (and, after a Section 7.01(c) Purchase Event, the Lower Tier REMIC 1 Uncertificated Regular Interests) and shall maintain books for the registration and for the transfer of Certificates (and, after a Section 7.01(c) Purchase Event, the Lower Tier REMIC 1 Uncertificated Regular Interests) (the “Certificate Register”). The Trustee may appoint a bank or trust company to act as Certificate Registrar. A registration book shall be maintained for the Certificates (and Lower Tier REMIC 1 Uncertificated Regular Interests, as the case may be) collectively. The Certificate Registrar may resign or be discharged or removed and a new successor may be appointed in accordance with the procedures and requirements set forth in Sections 6.06 and 6.07 hereof with respect to the resignation, discharge or removal of the Trustee and the appointment of a successor Trustee. The Certificate Registrar may appoint, by a written instrument delivered to the Holders and the Master Servicer, any bank or trust company to act as co-registrar under such conditions as the Certificate Registrar may prescribe; provided, however, that the Certificate Registrar shall not be relieved of any of its duties or responsibilities hereunder by reason of such appointment.

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

Section 3.03

Transfer and Exchange of Certificates.

(a)

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

(b)

A Certificate may be exchanged by the Holder thereof for any number of new Certificates of the same Class, in authorized denominations, representing in the aggregate the same Certificate Principal Amount or Percentage Interest as the Certificate surrendered, upon surrender of the Certificate to be exchanged at the office of the Certificate Registrar duly endorsed or accompanied by a written instrument of transfer duly executed by such Holder or his duly authorized attorney in such form as is satisfactory to the Certificate Registrar. Certificates delivered upon any such exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Certificates surrendered. No service charge shall be made to a Certificateholder for any exchange of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, and the Trustee or the Authenticating Agent shall authenticate, date and deliver the Certificates which the Certificateholder making the exchange is entitled to receive.

(c)

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

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

(i)

The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is (x) to the Depositor or an affiliate (as defined in Rule 405 under the Securities Act) of the Depositor or (y) being made to a “qualified institutional buyer” (a “QIB”) as defined in Rule 144A under the Securities Act by a transferor that has provided the Trustee with a certificate in the form of Exhibit F hereto; and

(ii)

The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is being made to an “accredited investor” under Rule 501(a)(1), (2), (3) or (7) under the Securities Act, or to any Person all of the equity owners in which are such accredited investors, by a transferor who furnishes to the Trustee a letter of the transferee substantially in the form of Exhibit G hereto.

(d)

(i) No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate shall be made to any Person unless the Trustee has received (A) a certificate substantially in the form of Exhibit H hereto (or Exhibit D-1, in the case of a Residual Certificate) from such transferee or (B) an Opinion of Counsel, to the effect that the purchase and holding of such a Certificate will not constitute or result in prohibited transactions under Title I of ERISA or Section 4975 of the Code and will not subject the Trustee, the Master Servicer, any Servicer or the Depositor to any obligation in addition to those undertaken in the Agreement; provided, however, that the Trustee will not require such certificate or opinion in the event that, as a result of a change of law or otherwise, the Trustee receives an Opinion of Counsel to the effect that the purchase and holding of an ERISA-Restricted Certificate by a Plan or a Person that is purchasing or holding such a Certificate with the assets of a Plan will not constitute or result in a prohibited transaction under Title I of ERISA or Section 4975 of the Code. Each Transferee of an ERISA-Restricted Certificate that is a Book-Entry Certificate shall be deemed to have made the representations set forth in Exhibit H. The preparation and delivery of the certificate and opinions referred to above shall not be an expense of the Trust Fund, the Trustee, the Master Servicer, any Servicer or the Depositor.

Notwithstanding the foregoing, no opinion or certificate shall be required for the initial issuance of the ERISA-Restricted Certificates. The Trustee shall have no obligation to monitor transfers of Book-Entry Certificates that are ERISA-Restricted Certificates and shall have no liability for transfers of such Certificates in violation of the transfer restrictions. The Trustee shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 3.03(d) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trustee in accordance with the foregoing requirements. The Trustee shall be entitled, but not obligated, to recover from any Holder of any ERISA-Restricted Certificate that was in fact a Plan or a Person acting on behalf of any such Plan any payments made on such ERISA-Restricted Certificate at and after either such time. Any such payments so recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Holder of such Certificate that is not such a Plan or Person acting on behalf of a Plan.

(ii)

No transfer of an ERISA-Restricted Swap Certificate prior to the termination of the Swap Agreement shall be made unless the Trustee shall have received a representation letter from the transferee of such Certificate, substantially in the form set forth in Exhibit H, to the effect that either (i) such transferee is neither a Plan nor a Person acting on behalf of any such Plan or using the assets of any such Plan to effect such transfer or (ii) the acquisition and holding of the ERISA-Restricted Swap Certificate are eligible for exemptive relief under Prohibited Transaction Class Exemption (“PTCE”) 84-14, ▇▇▇▇ ▇▇-▇, ▇▇▇▇ ▇▇-▇▇, ▇▇▇▇ 95-60 or PTCE 96-23. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Swap Certificate prior to the termination of the Swap Agreement to or on behalf of a Plan without the delivery to the Trustee of a representation letter as described above shall be void and of no effect. If the ERISA-Restricted Swap Certificate is a Book-Entry Certificate, prior to the termination of the Swap Agreement, the transferee will be deemed to have made a representation as provided in clause (i) or (ii) of this paragraph, as applicable.

If any ERISA-Restricted Swap Certificate, or any interest therein, is acquired or held in violation of the provisions of the preceding paragraph, the next preceding permitted beneficial owner will be treated as the beneficial owner of that Certificate, retroactive to the date of transfer to the purported beneficial owner. Any purported beneficial owner whose acquisition or holding of an ERISA-Restricted Swap Certificate, or interest therein, was effected in violation of the provisions of the preceding paragraph shall indemnify to the extent permitted by law and hold harmless the Depositor, the Trustee and the Master Servicer from and against any and all liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition or holding.

To the extent permitted under applicable law (including, but not limited to, ERISA), the Trustee shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Swap Certificate that is in fact not permitted by this Section 3.03(d)(ii) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Trustee in accordance with the foregoing requirements.

(e)

As a condition of the registration of transfer or exchange of any Certificate, the Certificate Registrar may require the certified taxpayer identification number of the owner of the Certificate and the payment of a sum sufficient to cover any tax or other governmental charge imposed in connection therewith; provided, however, that the Certificate Registrar shall have no obligation to require such payment or to determine whether or not any such tax or charge may be applicable. No service charge shall be made to the Certificateholder for any registration, transfer or exchange of a Certificate.

Notwithstanding anything to the contrary contained herein, no Residual Certificate may be owned, pledged or transferred, directly or indirectly, by or to (i) a Disqualified Organization or (ii) an individual, corporation or partnership or other person unless such person is (A) not a Non-U.S. Person or (B) is a Non-U.S. Person that holds a Residual Certificate in connection with the conduct of a trade or business within the United States and has furnished the transferor and the Trustee with an effective Internal Revenue Service W-8ECI or successor form at the time and in the manner required by the Code (any such person who is not covered by clause (A) or (B) above is referred to herein as a “Non-permitted Foreign Holder”).

Prior to and as a condition of the registration of any transfer, sale or other disposition of a Residual Certificate, the proposed transferee shall deliver to the Trustee an affidavit in substantially the form attached hereto as Exhibit D-1 representing and warranting, among other things, that such transferee is not a Disqualified Organization, an agent or nominee acting on behalf of a Disqualified Organization or a Non-Permitted Foreign Holder (any such transferee, a “Permitted Transferee”), and the proposed transferor shall deliver to the Trustee an affidavit in substantially the form attached hereto as Exhibit D-2. In addition, the Trustee may (but shall have no obligation to) require, prior to and as a condition of any such transfer, the delivery by the proposed transferee of an Opinion of Counsel, addressed to the Depositor, the Master Servicer and the Trustee satisfactory in form and substance to the Depositor, that such proposed transferee or, if the proposed transferee is an agent or nominee, the proposed beneficial owner, is not a Disqualified Organization, agent or nominee thereof, or a Non-Permitted Foreign Holder. Notwithstanding the registration in the Certificate Register of any transfer, sale, or other disposition of a Residual Certificate to a Disqualified Organization, an agent or nominee thereof, or Non-Permitted Foreign Holder, such registration shall be deemed to be of no legal force or effect whatsoever and such Disqualified Organization, agent or nominee thereof, or Non-Permitted Foreign Holder shall not be deemed to be a Certificateholder for any purpose hereunder, including, but not limited to, the receipt of distributions on such Residual Certificate. The Trustee shall not be under any liability to any person for any registration or transfer of a Residual Certificate to a Disqualified Organization, agent or nominee thereof or Non-permitted Foreign Holder or for the maturity of any payments due on such Residual Certificate to the Holder thereof or for taking any other action with respect to such Holder under the provisions of the Agreement, so long as the transfer was effected in accordance with this Section 3.03(e), unless a Responsible Officer of the Trustee shall have actual knowledge at the time of such transfer or the time of such payment or other action that the transferee is a Disqualified Organization, or an agent or nominee thereof, or Non-permitted Foreign Holder. The Trustee shall be entitled, but not obligated, to recover from any Holder of a Residual Certificate that was a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder at the time it became a Holder or any subsequent time it became a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder, all payments made on such Residual Certificate at and after either such times (and all costs and expenses, including but not limited to attorneys’ fees, incurred in connection therewith). Any payment (not including any such costs and expenses) so recovered by the Trustee shall be paid and delivered to the last preceding Holder of such Residual Certificate.

If any purported transferee shall become a registered Holder of a Residual Certificate in violation of the provisions of this Section 3.03(e), then upon receipt of written notice to the Trustee that the registration of transfer of such Residual Certificate was not in fact permitted by this Section 3.03(e), the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of such registration of transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of transfer of a Residual Certificate that is in fact not permitted by this Section 3.03(e), for making any payment due on such Certificate to the registered Holder thereof or for taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered upon receipt of the affidavit described in the preceding paragraph of this Section 3.03(e).

(f)

Each Holder or Certificate Owner of a Restricted Certificate, ERISA-Restricted Certificate or Residual Certificate, or an interest therein, by such Holder’s or Owner’s acceptance thereof, shall be deemed for all purposes to have consented to the provisions of this section.

(g)

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

(A)

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

(B)

(iii)

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

All such Eligible Investments shall be made in the name of the Master Servicer in trust for the benefit of the Trustee and Holders of the Structured Asset Securities Corporation Mortgage Pass-Through Certificates, Series 2006-S2. All income and gain realized from any Eligible Investment shall be for the benefit of the Master Servicer and shall be subject to its withdrawal or order from time to time, subject to Section 5.05 hereof, and shall not be part of the Trust Fund. The amount of any losses incurred in respect of any such investments shall be deposited in such Collection Account by the Master Servicer out of its own funds, without any right of reimbursement therefor, immediately as realized. The foregoing requirements for deposit in the Collection Account are exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments of interest on funds in the Collection Account and payments in the nature of late payment charges, assumption fees and other incidental fees and charges relating to the Mortgage Loans (other than Prepayment Premiums) need not be deposited by the Master Servicer in the Collection Account and may be retained by the Master Servicer or the applicable Servicer as additional servicing compensation. If the Master Servicer deposits in the Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from such Collection Account.

Section 4.02

Application of Funds in the Collection Account.

The Master Servicer may, from time to time, make, or cause to be made, withdrawals from the Collection Account for the following purposes:

(i)

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

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

(iii)

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

(iv)

to reimburse itself or any Servicer for expenses incurred by and recoverable by or reimbursable to it or any Servicer pursuant to this Agreement, including, without limitation, Sections 9.04, 9.05(b), 9.07(a), 9.30 or 11.15;

(v)

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

(vi)

subject to Section 5.05, to pay to itself income earned on the investment of funds deposited in the Collection Account;

(vii)

to make payments to the Trustee on each Master Servicer Remittance Date for deposit into the Certificate Account in the amount provided in Section 4.04;

(viii)

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

(ix)

to withdraw funds deposited in error in the Collection Account;

(x)

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

(xi)

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

(xii)

to reimburse any Servicer for such amounts as are due thereto under the applicable Servicing Agreement and have not been retained by or paid to such Servicer, to the extent provided in such Servicing Agreement.

In the event that the Master Servicer fails on any Master Servicer Remittance Date to remit to the Trustee any amounts required to be so remitted to the Trustee pursuant to sub-clause (vii) by such date, the Master Servicer shall pay the Trustee, for the account of the Trustee, interest calculated at the “prime rate” (as published in the “Money Rates” section of The Wall Street Journal) on such amounts not timely remitted for the period from and including that Master Servicer Remittance Date to but not including the related Distribution Date. The Master Servicer shall only be required to pay the Trustee interest for the actual number of days such amounts are not timely remitted (e.g., one day's interest, if such amounts are remitted one day after the Master Servicer Remittance Date).

In connection with withdrawals made pursuant to subclauses (i), (iii), and (v) above, the Master Servicer’s, any Servicer’s or such other Person’s entitlement thereto is limited to collections or other recoveries on the related Mortgage Loan.

Section 4.04

Certificate Account.

(a)

The Trustee shall establish and maintain in its name, as trustee, a trust account (the “Certificate Account”) entitled “Certificate Account, Citibank, N.A., as Trustee, in trust for the benefit of the Holders of Structured Asset Securities Corporation Mortgage Pass-Through Certificates, Series 2006-S2” until disbursed pursuant to the terms of this Agreement. The Certificate Account shall be an Eligible Account and shall be for the benefit of the Certificateholders, subject to the rights of the Trustee set forth herein. If the existing Certificate Account ceases to be an Eligible Account, the Trustee shall establish a new Certificate Account that is an Eligible Account within 10 Business Days and transfer all funds and investment property on deposit in such existing Certificate Account into such new Certificate Account. The Certificate Account shall relate solely to the Certificates and the Lower Tier REMIC 1 Uncertificated Regular Interests issued hereunder and funds in the Certificate Account shall be held separate and apart from and shall not be commingled with any other monies including, without limitation, other monies of the Trustee held under this Agreement.

(b)

The Trustee shall deposit or cause to be deposited into the Certificate Account, on the day on which, or, if such day is not a Business Day, the Business Day immediately following the day on which, any monies are remitted by the Master Servicer to the Trustee, all such amounts. The Trustee shall make withdrawals from the Certificate Account only for the following purposes:

(i)

to make payment to itself pursuant to any provision of this Agreement or to reimburse itself or its agents for any amounts reimbursable to it pursuant to Sections 6.11, 6.12 or 7.01; provided, however, that any amounts in excess of the annual cap described in clause (b) of the definition of “Interest Remittance Amount” and clause (b) of the definition of “Principal Remittance Amount” in any Anniversary Year, other than costs and expenses incurred by the Trustee pursuant to Section 6.14, in connection with any transfer of servicing, shall not be withdrawn from the Certificate Account and paid to the Trustee and the Trustee’s reimbursement for such excess amounts shall be made pursuant to Section 5.02(b)(v) hereof;

(ii)

to withdraw amounts deposited in the Certificate Account in error;

(iii)

to pay itself any investment income earned with respect to funds in the Certificate Account invested in Eligible Investments as set forth below and to make payments to itself and others pursuant to any provision of this Agreement;

(iv)

to make distributions to Certificateholders pursuant to Article V; and

(v)

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

Funds in the Certificate Account may be invested by the Trustee in Eligible Investments (which may be obligations of the Trustee or its affiliates). If invested, all such investments must be payable on demand or mature no later than one Business Day prior to the next Distribution Date, and shall not be sold or disposed of prior to their maturity. All such Eligible Investments will be made in the name of the Trustee (in its capacity as such) or its nominee. All income and gain realized from any such investment for each Distribution Date shall be compensation to the Trustee and be subject to withdrawal by the Trustee from time to time. The amount of any losses incurred in respect of any such investments shall be paid by the Trustee for deposit in the Certificate Account out of its own funds, without any right of reimbursement therefor, immediately as realized. Funds held in the Certificate Account may also be held uninvested.

Distributions Generally.

(a)

Subject to Section 7.01 respecting the final distribution on the Certificates or Lower Tier REMIC 1 Uncertificated Regular Interests, on each Distribution Date the Trustee or the Paying Agent shall make distributions in accordance with this Article V. Such distributions shall be made by wire transfer if the Certificateholder has provided the Trustee with wire instructions or by check mailed to the address of such Certificateholder as it appears in the books of the Trustee if the Certificateholder has not provided the Trustee with wire instructions in immediately available funds to an account specified in the request and at the expense of such Certificateholder.

(b)

The final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office; provided, however, that the foregoing provisions shall not apply to any Class of Certificates as long as such Certificate remains a Book-Entry Certificate in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of each REMIC and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office. If any payment required to be made on the Certificates or Lower Tier REMIC 1 Uncertificated Regular Interests is to be made on a day that is not a Business Day, then such payment will be made on the next succeeding Business Day.

(c)

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

Advances by Master Servicer, Servicer and Trustee.

(a)

Subject to Section 9.07, Advances shall be made in respect of each Master Servicer Remittance Date as provided herein. If, on any Determination Date, any Servicer determines that any Scheduled Payments due during the related Collection Period (other than Balloon Payments) have not been received, such Servicer shall advance such amount to the extent provided in the applicable Servicing Agreement. If any Servicer fails to remit Advances required to be made under the applicable Servicing Agreement, the Master Servicer shall itself make, or shall cause the successor Servicer to make, such Advance on the Master Servicer Remittance Date immediately following such Determination Date. If the Master Servicer determines that an Advance is required, it shall on the Master Servicer Remittance Date immediately following such Determination Date either (i) remit to the Trustee from its own funds (or funds advanced by the applicable Servicer) for deposit in the Certificate Account immediately available funds in an amount equal to such Advance, (ii) cause to be made an appropriate entry in the records of the Collection Account that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 5.04, used by the Master Servicer to make such Advance, and remit such immediately available funds to the Trustee for deposit in the Certificate Account or (iii) make Advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any funds being held in the Collection Account for future distribution to Certificateholders and so used shall be replaced by the Master Servicer from its own funds by remittance to the Trustee for deposit in the Certificate Account on or before any future Master Servicer Remittance Date to the extent that funds in the Certificate Account on such Master Servicer Remittance Date shall be less than payments to Certificateholders required to be made on the related Distribution Date. The Master Servicer and the Servicer shall be entitled to be reimbursed from the Collection Account for all Advances made by it as provided in Section 4.02. Notwithstanding anything to the contrary herein, in the event the Master Servicer determines in its reasonable judgment that an Advance is non-recoverable, the Master Servicer shall be under no obligation to make such Advance. The Trustee shall be entitled to conclusively rely upon any determination by the Master Servicer that an Advance, if made, would constitute a non-recoverable Advance.

(b)

In the event that the Master Servicer or any Servicer fails for any reason to make an Advance required to be made pursuant to this Section 5.04 on or before the Master Servicer Remittance Date, the Trustee, solely in its capacity as successor Master Servicer pursuant to Section 6.14, shall, on or before the related Distribution Date, deposit in the Certificate Account an amount equal to the excess of (a) Advances required to be made by the Master Servicer or the Servicer that would have been deposited in such Certificate Account over (b) the amount of any Advance made by the Master Servicer or any Servicer with respect to such Distribution Date; provided, however, that the Trustee shall be required to make such Advance only if it is not prohibited by law from doing so and it has determined that such Advance would be recoverable from amounts to be received with respect to such Mortgage Loan, including late payments, Liquidation Proceeds, Insurance Proceeds, or otherwise. The Trustee shall be entitled to be reimbursed from the Certificate Account for Advances made by it pursuant to this Section 5.04 as if it were the Master Servicer.

(a)

On the Closing Date, the Trustee shall establish and maintain in its name, in trust for the benefit of the Certificateholders, a Basis Risk Reserve Fund, into which ▇▇▇▇▇▇ Brothers Holdings Inc.

The Basis Risk Reserve Fund shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other monies, including, without limitation, other monies of the Trustee held pursuant to this Agreement.

(b)

On each Distribution Date, the Trustee shall distribute in the order of priority and to the extent specified in Section 5.02(d)(iv) of this Agreement the Basis Risk Payment, if any, for such Distribution Date.

(c)

Funds in the Basis Risk Reserve Fund shall be invested in Eligible Investments. The Class M2 Certificates shall evidence ownership of the Basis Risk Reserve Fund for federal income tax purposes and LBH on behalf of the Holder thereof shall direct the Trustee, in writing, as to investment of amounts on deposit therein. LBH shall be liable for any losses incurred on such investments. In the absence of written instructions from LBH as to investment of funds on deposit in the Basis Risk Reserve Fund, such funds shall remain uninvested. The Basis Risk Reserve Fund will be terminated after a Trust Fund Termination Event.

Section 5.07

Supplemental Interest Trust.

(a)

A separate trust is hereby established (the “Supplemental Interest Trust”), the corpus of which shall be held by the Trustee in trust for the benefit of the Certificateholders and the Swap Counterparty. The Trustee, as trustee of the Supplemental Interest Trust, shall establish an account (the “Supplemental Interest Trust Account”), into which LBH shall initially deposit $1,000. The Supplemental Interest Trust Account shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other monies, including, without limitation, other monies of the Trustee held pursuant to this Agreement.

(b)

The Trustee shall deposit into the Supplemental Interest Trust Account any Net Swap Payment required pursuant to Sections 5.02(b), (c) and (e), any Swap Termination Payment required pursuant to Sections 5.02(b), (c) and (e), any amounts received from the Swap Counterparty under the Swap Agreement and any amounts distributed from the Basis Risk Reserve Fund required pursuant to Sections 5.02(d)(iv)(C) and (d)(vii), and shall distribute from the Supplemental Interest Trust Account any Net Swap Payment required pursuant to Section 5.02(e)(i) or Section 5.02(i), applicable, or Swap Termination Payment required pursuant to Sections 5.02(e)(ii) and 5.02(e)(x) or Section 5.02(i), as applicable.

(c)

Funds in the Supplemental Interest Trust Account shall be invested in Eligible Investments. Any earnings on such amounts shall be distributed on each Distribution Date pursuant to Section 5.02(e) or Section 5.02 (i), as applicable. The Class M2 Certificates shall evidence ownership of the Supplemental Interest Trust Account for federal income tax purposes and the Holder thereof shall direct the Trustee, in writing, as to investment of amounts on deposit therein. LBH shall be liable for any losses incurred on such investments. In the absence of written instructions from the Class M2 Certificateholders as to investment of funds on deposit in the Supplemental Interest Trust Account, such funds shall remain uninvested. Any amounts on deposit in the Supplemental Interest Trust Account in excess of the Swap Amount on any Distribution Date shall be held for distribution pursuant to Section 5.02(e) or Section 5.02(i), as applicable, on the following Distribution Date.

(d)

Upon termination of the Trust Fund, any amounts remaining in the Supplemental Interest Trust Account shall be distributed pursuant to the priorities set forth in Section 5.02(e) or Section 5.02(i), as applicable.

(e)

It is the intention of the parties hereto that, for federal and state income and state and local franchise tax purposes, the Supplemental Interest Trust be disregarded as an entity separate from the holder of the Class M2 Certificates unless and until the date when either (a) there is more than one Class M2 Certificateholder or (b) any Class of Certificates in addition to the Class M2 Certificates is recharacterized as an equity interest in the Supplemental Interest Trust for federal income tax purposes. The Trustee shall not be responsible for any entity level tax reporting for the Supplemental Interest Trust.

(f)

To the extent that the Supplemental Interest Trust is determined to be a separate legal entity from the Trustee, any obligation of the Trustee under the Swap Agreement shall be deemed to be an obligation of the Supplemental Interest Trust.

Section 5.08

Rights of Swap Counterparty.

The Swap Counterparty shall be deemed a third-party beneficiary of this Agreement to the same extent as if it were a party hereto and shall have the right, upon designation of an “Early Termination Date” (as defined in the Swap Agreement), to enforce its rights under this Agreement, which rights include but are not limited to the obligation of the Trustee (A) to deposit any Net Swap Payment required pursuant to Sections 5.02(b), (c) and (e) and any Swap Termination Payment required pursuant to Sections 5.02(b), (c) and (e) into the Supplemental Interest Trust Account, (B) to deposit any amounts from the Basis Risk Reserve Fund required pursuant to Sections 5.02(d)(iv)(C) into the Supplemental Interest Trust Account, (C) to pay any Net Swap Payment required pursuant to Section 5.02(e)(i) and Section 5.02(i), as applicable, or Swap Termination Payment required pursuant to Section 5.02(e)(ii) and Section 5.02(e)(x) or Section 5.02(i), as applicable, to the Swap Counterparty and (D) to establish and maintain the Supplemental Interest Trust Account, to make such deposits thereto, investments therein and distributions therefrom as are required pursuant to Section 5.07.

Section 5.09

Swap Termination Receipts.

(a)

In the event of an “Early Termination Event” as defined under the Swap Agreement, (i) any Swap Termination Payment made by the Swap Counterparty to the Supplemental Interest Trust paid pursuant to Section 5.02(e)(ix), Section 5.02(h) or Section 5.02(i), as applicable, (“Swap Termination Receipts”) will be deposited in a segregated non-interest bearing account which shall be an Eligible Account established by the Trustee (the “Swap Termination Receipts Account”) and (ii) any amounts received from a replacement Swap Counterparty (“Swap Replacement Receipts”) will be deposited in a segregated non-interest bearing account which shall be an Eligible Account established by the Trustee (the “Swap Replacement Receipts Account”). Solely upon written direction of the Depositor, the Trustee shall invest, or cause to be invested, funds held in the Swap Termination Receipts Account and the Swap Replacement Receipts Account in time deposits of the Trustee as permitted by clause (ii) of the definition of Eligible Investments or as otherwise directed in writing by a majority of the Certificateholders. All such investments must be payable on demand or mature on a Swap Payment Date, a Distribution Date or such other date as directed by the Certificateholders. If no such direction is given by the Depositor, such funds shall remain uninvested. All such Eligible Investments will be made in the name of the Trustee of the Supplemental Interest Trust (in its capacity as such) or its nominee. All income and gain realized from any such investment shall be deposited in the Swap Termination Receipts Account or the Swap Replacement Receipts Account, as applicable, and all losses, if any, shall be borne by the related account.

Unless otherwise permitted by the Rating Agencies as evidenced in a written confirmation, the Depositor shall arrange for replacement Swap Agreement(s) and the Trustee shall promptly, at the written direction of the Depositor, use amounts on deposit in the Swap Termination Receipts Account, if necessary, to enter into replacement Swap Agreement(s) which shall be executed and delivered by the Trustee on behalf of the Supplemental Interest Trust upon receipt of written confirmation from each Rating Agency that such replacement Swap Agreement(s) will not result in the reduction or withdrawal of the rating of any outstanding Class of Certificates with respect to which it is a Rating Agency.

Amounts on deposit in the Swap Replacement Receipts Account shall be held for the benefit of the related Swap Counterparty and paid to such Swap Counterparty if the Supplemental Interest Trust is required to make a payment to such Swap Counterparty following an event of default or termination event with respect to the Supplemental Interest Trust under the related Swap Agreement. Any amounts not so applied shall, following the termination or expiration of such Swap Agreement, be paid to the Class M2 Certificates.

If an Event of Default (of which a Responsible Officer of the Trustee shall have actual knowledge) has occurred and has not otherwise been cured or waived, the Trustee shall exercise such of the rights and powers vested in it by this Agreement and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

No provision of this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and none of the provisions contained in this Agreement shall in any event require the Trustee to perform, or be responsible for the manner of performance of, any of the obligations of the Depositor or the Master Servicer under this Agreement; and

Unless and until a Form 15 suspension notice shall have been filed, as a condition to the succession to the Trustee under this Agreement by any Person (i) into which the Trustee may be merged or consolidated, or (ii) which may be appointed as a successor to the Trustee, the Trustee shall notify the Sponsor, the Master Servicer and the Depositor, at least 15 calendar days prior to the effective date of such succession or appointment, of such succession or appointment and shall furnish to the Sponsor, the Master Servicer and the Depositor in writing and in form and substance reasonably satisfactory to the Sponsor, the Master Servicer and the Depositor, all information reasonably necessary for the Trustee to accurately and timely report, pursuant to Section 6.20, the event under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports under the Exchange Act are required to be filed under the Exchange Act).

Section 6.09

Appointment of Co-Trustee, Separate Trustee or Custodian.

(a)

Notwithstanding any other provisions hereof, at any time, the Trustee, the Depositor or the Certificateholders evidencing more than 50% of the Class Principal Amount (or Percentage Interest) of every Class of Certificates shall have the power from time to time to appoint one or more Persons, approved by the Trustee, to act either as co-trustees jointly with the Trustee, or as separate trustees, or as custodians, for the purpose of holding title to, foreclosing or otherwise taking action with respect to any Mortgage Loan outside the state where the Trustee has its principal place of business where such separate trustee or co-trustee is necessary or advisable (or the Trustee has been advised by the Master Servicer that such separate trustee or co-trustee is necessary or advisable) under the laws of any state in which a property securing a Mortgage Loan is located or for the purpose of otherwise conforming to any legal requirement, restriction or condition in any state in which a property securing a Mortgage Loan is located or in any state in which any portion of the Trust Fund is located. The separate Trustees, co-trustees or custodians so appointed shall be trustees or custodians for the benefit of all the Certificateholders and shall have such powers, rights and remedies as shall be specified in the instrument of appointment; provided, however, that no such appointment shall, or shall be deemed to, constitute the appointee an agent of the Trustee. The Trustee shall not be responsible for any action or omission of any separate trustee, co-trustee or custodian. Notwithstanding the foregoing, at any time during the period that a Form 10-K is being filed with respect to the Trust Fund in accordance with the Exchange Act and the rules and regulations of the Commission, no such co-custodian or co-trustee shall be vested with any powers, rights and remedies under this Agreement unless such party has agreed to comply with all Regulation AB requirements set forth under this Agreement or the related Custodial Agreement, as applicable.

(b)

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

(i)

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

(ii)

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

(iii)

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

(iv)

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

(c)

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

(d)

Any separate trustee, co-trustee or custodian may, at any time, constitute the Trustee its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee, co-trustee or custodian shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

(e)

No separate trustee, co-trustee or custodian hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 6.05 hereunder and no notice to Certificateholders of the appointment shall be required under Section 6.07 hereof.

(f)

The Trustee agrees to instruct the co-trustees, if any, to the extent necessary to fulfill the Trustee’s obligations hereunder.

(g)

The Trustee shall pay the reasonable compensation of the co-trustees requested by the Trustee to be so appointed (which compensation shall not reduce any compensation payable to the Trustee ) and, if paid by the Trustee, shall be a reimbursable expense pursuant to Section 6.12.

Section 6.10

Authenticating Agents.

(a)

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

(b)

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

(c)

Any Authenticating Agent may at any time resign by giving at least 30 days’ advance written notice of resignation to the Trustee and the Depositor. The Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and the Depositor. Upon receiving a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.10, the Trustee may appoint a successor Authenticating Agent, shall give written notice of such appointment to the Depositor and shall mail notice of such appointment to all Holders of Certificates. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named as Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 6.10. No Authenticating Agent shall have responsibility or liability for any action taken by it as such at the direction of the Trustee. Any Authenticating Agent shall be entitled to reasonable compensation for its services and, if paid by the Trustee, it shall be a reimbursable expense pursuant to Section 6.12.

Section 6.11

Indemnification of Trustee.

The Trustee and its directors, officers, employees and agents shall be entitled to indemnification from the Trust Fund for any loss, liability or expense incurred in connection with any legal proceeding or incurred without negligence or willful misconduct on their part arising out of, or in connection with, the acceptance or administration of the trusts created hereunder or in connection with the performance of their duties hereunder or under the Swap Agreement, the Mortgage Loan Sale Agreement, each Transfer Agreement, each Servicing Agreement or each Custodial Agreement, including any applicable fees and expenses payable pursuant to Section 6.12 and the costs and expenses of defending themselves against any claim in connection with the exercise or performance of any of their powers or duties hereunder, provided that:

(i)

with respect to any such claim, the Trustee shall have given the Depositor, the Master Servicer and the Holders written notice thereof promptly after a Responsible Officer of the Trustee shall have knowledge thereof, provided that the failure to provide such prompt written notice shall not affect the Trustee’s right to indemnification hereunder;

(ii)

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

(iii)

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

The Trustee shall be further indemnified by the Seller for and held harmless against, any loss, liability or expense arising out of, or in connection with, the provisions set forth in the fourth paragraph of Section 2.01(a) hereof, including, without limitation, all costs, liabilities and expenses (including reasonable legal fees and expenses) of investigating and defending itself against any claim, action or proceeding, pending or threatened, relating to the provisions of such paragraph.

The provisions of this Section 6.11 shall survive any termination of this Agreement and the resignation or removal of the Trustee and shall be construed to include, but not be limited to any loss, liability or expense under any environmental law.

Section 6.12

Fees and Expenses of Trustee and Custodians.

The Trustee shall be entitled to receive, and is authorized to pay itself, any investment income and earnings on the Certificate Account. The Trustee shall be entitled to reimbursement of all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with this Agreement (including fees and expenses of its counsel and all persons not regularly in its employment and any amounts described in Section 10.01 to which the Trustee is entitled as provided therein), except for expenses, disbursements and advances that either (i) do not constitute “unanticipated expenses” within the meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii) or (ii) arise from its negligence, bad faith or willful misconduct. Each Custodian shall receive compensation and reimbursement or payment of its expenses under the related Custodial Agreement as provided therein; provided that to the extent required under Section 6 or Section 20 of the Custodial Agreement, the Trustee is hereby authorized to pay such compensation or reimbursement from amounts on deposit in the Certificate Account prior to any distributions to Certificateholders pursuant to Section 5.02 hereof.

Section 6.13

Collection of Monies.

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

(v)

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, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer, and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days or any Rating Agency reduces or withdraws or threatens to reduce or withdraw the rating of the Certificates because of the financial condition or loan servicing capability of such Master Servicer; or

(vi)

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

(vii)

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

(x)

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

(xi)

(xii)

After receipt of notice from the Trustee, any failure of the Master Servicer to remit to the Trustee any payment required to be made to the Trustee for the benefit of Certificateholders under the terms of this Agreement, including any Advance, on any Master Servicer Remittance Date which failure continues unremedied for a period of one Business Day (but in no event later than 12:00 p.m. New York City time on the related Distribution Date) after the date upon which notice of such failure shall have been given to the Master Servicer by the Trustee.

If an Event of Default described in clauses (i) through (xii) of this Section shall occur, then, in each and every case, subject to applicable law, so long as any such Event of Default shall not have been remedied within any period of time prescribed by this Section, the Trustee, by notice in writing to the Master Servicer may, and shall, if so directed by Certificateholders evidencing more than 50% of the Class Principal Amount (or Class Notional Amount) of each Class of Certificates, terminate all of the rights and obligations of the Master Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof. If an Event of Default described in clause (xii) of this Section shall occur, then, in each and every case, subject to applicable law, so long as such Event of Default shall not have been remedied within the time period prescribed by clause (xii) of this Section 6.14, the Trustee, by notice in writing to the Master Servicer, shall promptly terminate all of the rights and obligations of the Master Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof. On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer, and only in its capacity as Master Servicer under this Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee and pursuant to and under the terms of this Agreement; provided, however, the parties acknowledge that notwithstanding the preceding sentence there may be a transition period, not to exceed 90 days, in order to effect the transfer of the Master Servicing obligations to the Trustee. The Trustee is hereby authorized and empowered to execute and deliver, on behalf of the defaulting Master Servicer as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents or otherwise. The defaulting Master Servicer agrees to cooperate with the Trustee in effecting the termination of the defaulting Master Servicer’s responsibilities and rights hereunder as Master Servicer including, without limitation, notifying the Servicer of the assignment of the master servicing function and providing the Trustee or its designee all documents and records in electronic or other form reasonably requested by it to enable the Trustee or its designee to assume the defaulting Master Servicer’s functions hereunder and the transfer to the Trustee or its designee for administration by it of all amounts which shall at the time be or should have been deposited by the defaulting Master Servicer in the Collection Account maintained by such defaulting Master Servicer and any other account or fund maintained with respect to the Certificates or thereafter received with respect to the Mortgage Loans. The Master Servicer being terminated (or the Trust Fund, if the Master Servicer is unable to fulfill its obligations hereunder) as a result of an Event of Default shall bear all costs of a master servicing transfer, including but not limited to those of the Trustee reasonably allocable to specific employees and overhead, legal fees and expenses, accounting and financial consulting fees and expenses, and costs of amending the Agreement, if necessary.

The Trustee shall be entitled to be reimbursed from the Master Servicer (or by the Trust Fund, if the Master Servicer is unable to fulfill its obligations hereunder) for all costs associated with the transfer of master servicing from the predecessor Master Servicer, including, without limitation, any costs or expenses associated with the complete transfer of all master servicing data and the completion, correction or manipulation of such servicing data as may be required by the Trustee to correct any errors or insufficiencies in the master servicing data or otherwise to enable the Trustee to master service the Mortgage Loans properly and effectively. If the terminated Master Servicer does not pay such reimbursement within thirty (30) days of its receipt of an invoice therefor, such reimbursement shall be an expense of the Trust Fund and the Trustee shall be entitled to withdraw such reimbursement from amounts on deposit in the Certificate Account pursuant to Section 4.04(b); provided that the terminated Master Servicer shall reimburse the Trust Fund for any such expense incurred by the Trust Fund; and provided, further, that the Trustee shall decide whether and to what extent it is in the best interest of the Certificateholders to pursue any remedy against any party obligated to make such reimbursement.

Notwithstanding the termination of its activities as Master Servicer, each terminated Master Servicer shall continue to be entitled to reimbursement to the extent provided in Section 4.02 to the extent such reimbursement relates to the period prior to such Master Servicer’s termination.

If any Event of Default shall occur of which a Responsible Officer of the Trustee ahs actual knowledge, the Trustee shall promptly notify the Swap Counterparty and each Rating Agency of the nature and extent of such Event of Default. The Trustee shall immediately give written notice to the Master Servicer upon the Master Servicer’s failure to remit funds on the Master Servicer Remittance Date.

(b)

Within 90 days of the time the Master Servicer receives a notice of termination from the Trustee pursuant to Section 6.14(a) or the Trustee receives the resignation of the Master Servicer evidenced by an Opinion of Counsel pursuant to Section 9.28, the Trustee, unless another master servicer shall have been appointed, shall be the successor in all respects to the Master Servicer in its capacity as such under this Agreement and the transactions set forth or provided for herein and shall have all the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto and arising thereafter placed on the Master Servicer hereunder, including the obligation to make Advances; provided, however, that any failure to perform such duties or responsibilities caused by the Master Servicer’s failure to provide information required by this Agreement shall not be considered a default by the Trustee hereunder. In addition, the Trustee shall have no responsibility for any act or omission of the Master Servicer prior to the issuance of any notice of termination and within a period of time not to exceed 90 days after the issuance of written notice of termination pursuant to Section 6.14(a) or Section 9.28 or for any breach of representation or warranty by such predecessor Master Servicer. The Trustee shall have no liability relating to the representations and warranties of the Master Servicer set forth in Section 9.14. In the Trustee’s capacity as such successor, the Trustee shall have the same limitations on liability herein granted to the Master Servicer. As compensation therefor, the Trustee shall be entitled to receive all compensation payable to the Master Servicer under this Agreement, including the Master Servicing Fee.

(c)

Notwithstanding the above, the Trustee may, if it shall be unwilling to continue to so act, or shall, if it is unable to so act, petition a court of competent jurisdiction to appoint, or appoint on its own behalf any established housing and home finance institution servicer, master servicer, servicing or mortgage servicing institution having a net worth of not less than $15,000,000 and meeting such other standards for a successor master servicer as are set forth in this Agreement, as the successor to such Master Servicer in the assumption of all of the responsibilities, duties or liabilities of the Master Servicer hereunder. Any entity designated by the Trustee as a successor master servicer may be an Affiliate of the Trustee; provided, however, that, unless such Affiliate meets the net worth requirements and other standards set forth herein for a successor master servicer, or the Trustee, in its individual capacity shall agree, at the time of such designation, to be and remain liable to the Trust Fund for such Affiliate’s actions and omissions in performing its duties hereunder. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted to the Master Servicer hereunder. The Trustee and such successor shall take such actions, consistent with this Agreement, as shall be necessary to effectuate any such succession and may make other arrangements with respect to the servicing to be conducted hereunder which are not inconsistent herewith. The Master Servicer shall cooperate with the Trustee and any successor master servicer in effecting the termination of the Master Servicer’s responsibilities and rights hereunder including, without limitation, notifying Mortgagors of the assignment of the master servicing functions and providing the Trustee and successor master servicer, as applicable, all documents and records in electronic or other form reasonably requested by it to enable it to assume the Master Servicer’s functions hereunder and the transfer to the Trustee or such successor master servicer, as applicable, all amounts which shall at the time be or should have been deposited by the Master Servicer in the Collection Account and any other account or fund maintained with respect to the Certificates or the Lower Tier REMIC 1 Uncertificated Regular Interests or thereafter be received with respect to the Mortgage Loans. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (i) the failure of the Master Servicer to deliver, or any delay in delivering, cash, documents or records to it, (ii) the failure of the Master Servicer to cooperate as required by this Agreement, (iii) the failure of the Master Servicer to deliver the Mortgage Loan data to the Trustee as required by this Agreement or (iv) restrictions imposed by any regulatory authority having jurisdiction over the Master Servicer.

Section 6.15

Additional Remedies of Trustee Upon Event of Default.

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

Section 6.16

Waiver of Defaults.

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

Section 6.17

Notification to Holders.

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

Section 6.18

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

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

Section 6.19

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

In the event that a Responsible Officer of the Trustee shall have actual knowledge of any action or inaction of the Master Servicer that would become an Event of Default upon the Master Servicer’s failure to remedy the same after notice, the Trustee shall give notice thereof to the Master Servicer and the Swap Counterparty. For all purposes of this Agreement, in the absence of actual knowledge by a Responsible Officer of the Trustee, the Trustee shall not be deemed to have knowledge of any failure of the Master Servicer or any other Event of Default unless notified in writing by the Depositor, the Master Servicer, the Swap Counterparty or the Certificateholders.

(a)

The respective obligations and responsibilities of the Trustee and the Master Servicer created hereby (other than the obligation of the Trustee to make payments to Certificateholders and the Swap Counterparty as set forth in Section 7.02, the obligation of the Master Servicer to make a final remittance to the Trustee pursuant to Section 4.01, and the obligations of the Master Servicer to the Trustee pursuant to Sections 9.10, 9.14 and 9.31) shall terminate on the earliest of (i) the final payment or other liquidation of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property, (ii) the sale of the property held by the Trust Fund in accordance with Section 7.01(b) and (iii) the Latest Possible Maturity Date; (each, a “Trust Fund Termination Event”); provided, however, that in no event shall the Trust Fund created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, the late Ambassador of the United States to the Court of St. James’s, living on the date hereof. Upon the occurrence of a Trust Fund Termination Event, each REMIC shall be terminated in a manner that shall qualify as a “qualified liquidation” under the REMIC Provisions as evidenced by an Opinion of Counsel provided to the Trustee at the expense of the Trust Fund.

(b)

On any Distribution Date occurring on or after the Initial Optional Termination Date, the Master Servicer or LTURI-holder, as applicable, with the prior written consent of the Seller, which consent shall not be unreasonably withheld, has the option to cause the Trust Fund to adopt a plan of complete liquidation pursuant to Section 7.03(a)(i) hereof to sell all of its property. Upon exercise of such option, the property of the Trust Fund shall be sold to the Master Servicer at a price (the “Termination Price”) equal to the sum of (i) 100% of the unpaid principal balance of each Mortgage Loan on the day of such purchase plus interest accrued thereon at the applicable Mortgage Rate with respect to any Mortgage Loan to the Due Date in the Collection Period immediately preceding the related Distribution Date to the date of such repurchase, (ii) the fair market value of any REO Property and any other property held by any REMIC, such fair market value to be determined by an independent appraiser or appraisers mutually agreed upon by the Master Servicer (reduced, in the case of REO Property, by (1) reasonably anticipated disposition costs and (2) any amount by which the fair market value as so reduced exceeds the outstanding principal balance of the related Mortgage Loan plus interest accrued thereon at the applicable Net Mortgage Rate to the date of such purchase), (iii) any unreimbursed Servicing Advances and (iv) any Swap Termination Payment payable to the Swap Counterparty as a result of a termination pursuant to this Section 7.01. The Master Servicer, the Servicer, the Trustee and the Custodian shall be reimbursed from the Termination Price for any Mortgage Loan or related REO Property for any Advances made or other amounts advanced with respect to the Mortgage Loans that are reimbursable to any such entity under this Agreement, the related Servicing Agreement or the related Custodial Agreement, together with any accrued and unpaid compensation and any other amounts due to the Master Servicer or the Trustee hereunder or the Servicer or the Custodians.

(c)

On any Distribution Date occurring on or after the Initial Optional Termination Date, the Master Servicer, with the prior written consent of the Seller, which consent shall not be unreasonably withheld, has the option to purchase all of the Lower Tier REMIC 1 Uncertificated Regular Interests. Upon exercise of such option, the Lower Tier REMIC 1 Uncertificated Regular Interests shall be sold to the Master Servicer at a price (the “Lower Tier REMIC 1 Uncertificated Regular Interests Purchase Price”) equal to the sum of (i) 100% of the unpaid principal balance of each Mortgage Loan on the day of such purchase plus interest accrued thereon at the applicable Mortgage Rate with respect to any Mortgage Loan to the Due Date in the Collection Period immediately preceding the related Distribution Date to the date of such repurchase and (ii) the fair market value of any REO Property and any other property held by any REMIC, such fair market value to be determined by an independent appraiser or appraisers mutually agreed upon by the Master Servicer and the Trustee (reduced, in the case of REO Property, by (1) reasonably anticipated disposition costs and (2) any amount by which the fair market value as so reduced exceeds the outstanding principal balance of the related Mortgage Loan plus interest accrued thereon at the applicable Net Mortgage Rate to the date of such purchase). If the Master Servicer elects to exercise such option, each REMIC created pursuant to this Agreement (other than REMIC 1) shall be terminated in such a manner so that the termination of each such REMIC shall qualify as a “qualified liquidation” under the REMIC Provisions and the Lower Tier REMIC 1 Uncertificated Regular Interests and the Class LT-R Certificates will evidence the entire beneficial interest in the property of the Trust Fund. Following a purchase of the Lower Tier REMIC 1 Uncertificated Regular Interests pursuant to this subsection, the Trust Fund (and REMIC 1) will remain outstanding and final payment on the Certificates (other than the Class LT-R Certificates) will be made in accordance with Sections 7.03(a)(iii) and 5.02. The Trust Fund will terminate upon the occurrence of a Trust Fund Termination Event, in accordance with Section 7.01(a).

Section 7.02

Procedure Upon Termination of Trust Fund or Purchase of Lower Tier REMIC 1 Uncertificated Regular Interests.

(a)

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

In the case of a Trust Fund Termination Event, such notice shall specify (A) the Distribution Date upon which final distribution on the Certificates or Lower Tier REMIC 1 Uncertificated Regular Interests of all amounts required to be distributed to Certificateholders pursuant to Section 5.02 will be made upon presentation and surrender of the Certificates at the Corporate Trust Office, and (B) that the Record Date otherwise applicable to such Distribution Date is not applicable, distribution being made only upon presentation and surrender of the Certificates at the office or agency of the Trustee therein specified. Upon any such Trust Fund Termination Event, the duties of the Certificate Registrar with respect to the Certificates or Lower Tier REMIC 1 Uncertificated Regular Interests shall terminate and the Trustee shall terminate or request the Master Servicer to terminate, the Collection Account it maintains, the Certificate Account and any other account or fund maintained with respect to the Certificates or Lower Tier REMIC 1 Uncertificated Regular Interests, subject to the Trustee’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment.

In the case of a purchase of the Lower Tier REMIC 1 Uncertificated Regular Interests, such notice shall specify (A) the Distribution Date upon which final distribution on the Certificates (other than the Class LT-R Certificates) of all amounts required to be distributed to Certificateholders pursuant to Section 5.02 (other than any distributions to the Class LT-R Certificates in respect of REMIC 1) will be made upon presentation and surrender of the Certificates (other than the Class LT-R Certificates) at the Corporate Trust Office, and (B) that the Record Date otherwise applicable to such Distribution Date is not applicable, distribution being made only upon presentation and surrender of the Certificates (other than the Class LT-R Certificates) at the office or agency of the Trustee therein specified. Upon any such purchase of the Lower Tier REMIC 1 Uncertificated Regular Interests, the duties of the Certificate Registrar with respect to the Certificates other than the Class LT-R Certificate shall terminate but the Trustee shall not terminate or request the Master Servicer to terminate, the Collection Account it maintains, the Certificate Account and any other account or fund maintained with respect to the Certificates, subject to the Trustee’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment. For all Distribution Dates following the Distribution Date on which the Master Servicer purchases the Lower Tier REMIC 1 Uncertificated Regular Interests, all amounts that would be distributed on the Certificates (other than the Class LT-R Certificate and exclusive of amounts payable from any fund held outside of REMIC 1) absent such purchase shall be payable to the LTURI-holder.

(b)

In the event that all of the Holders do not surrender their Certificates for cancellation within three months after the time specified in the above-mentioned written notice, the Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within one year after the second notice any Certificates shall not have been surrendered for cancellation, the Trustee may take appropriate steps to contact the remaining Certificateholders concerning surrender of such Certificates, and the cost thereof shall be paid out of the amounts distributable to such Holders. If within two years after the second notice any Certificates shall not have been surrendered for cancellation, the Trustee shall, subject to applicable state law relating to escheatment, hold all amounts distributable to such Holders for the benefit of such Holders. No interest shall accrue on any amount held by the Trustee and not distributed to a Certificateholder due to such Certificateholder’s failure to surrender its Certificate(s) for payment of the final distribution thereon in accordance with this Section.

(c)

Any reasonable expenses incurred by the Trustee in connection with any Trust Fund Termination Event or any purchase of the Lower Tier REMIC 1 Uncertificated Regular Interests shall be reimbursed from proceeds received from such termination or purchase.

(ii)

On the date specified for final payment of the Certificates (other than the Class LT-R Certificates, in the case of a purchase of the Lower Tier REMIC 1 Uncertificated Regular Interests), the Trustee shall make final distributions of principal and interest on such Certificates and shall pay, in the case of a Trust Fund Termination Event, any Swap Termination Payment owed to the Swap Counterparty on the related Swap Payment Date (to the extent not paid on previous Swap Payment Dates) in accordance with Section 5.02.

Charged-off Loans and Released Mortgage Loans.

Notwithstanding anything to the contrary contained in this Agreement, each Charged-off Loan that becomes a Released Mortgage Loan shall be released from the Trust Fund as soon as practicable after becoming a Released Mortgage Loan and shall no longer be an asset of any REMIC.

Thereafter (i) the Released Mortgage Transferee shall be entitled to any amounts subsequently received in respect of any such Released Mortgage Loans, (ii) the Released Mortgage Transferee may designate any servicer to service any such Released Mortgage Loan and (iii) the Released Mortgage Transferee may sell any such Released Mortgage Loan to a third party. For purposes of compliance with the REMIC Provisions, any such Released Mortgage Loan transferred to the Released Mortgage Transferee pursuant to this Section 7.04 and having any value as of the date of such transfer shall be treated as having been transferred by the related REMIC as additional compensation for services provided to such REMIC.

Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by Holders or Certificate Owner, if the Holder is a Clearing Agency, may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee, the Certificate Registrar and the Paying Agent and, where expressly required herein, to the Master Servicer. Such instrument or instruments (as the action embodies therein and evidenced thereby) are herein sometimes referred to as an “act” of the Holders signing such instrument or instruments.

Whenever such execution is by an officer of a corporation or a member of a partnership on behalf of such corporation or partnership, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the individual executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(a)

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

Such financial statements shall include a balance sheet, income statement, statement of retained earnings, statement of additional paid-in capital, statement of changes in financial position and all related notes and schedules and shall be in comparative form, certified by a nationally recognized firm of Independent Accountants to the effect that such statements were examined and prepared in accordance with generally accepted accounting principles applied on a basis consistent with that of the preceding year.

Section 9.04

Power to Act; Procedures.

(a)

The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article X hereof, and the Servicer shall have full power and authority (to the extent provided in the applicable Servicing Agreement) to do any and all things that it may deem necessary or desirable in connection with the servicing and administration of the Mortgage Loans, including but not limited to the power and authority (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan, in each case, in accordance with the provisions of this Agreement and the applicable Servicing Agreement, as applicable; provided that the Master Servicer shall not take, or knowingly permit any Servicer to take, any action that is inconsistent with or prejudices the interests of the Trust Fund or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee, the Certificateholders under this Agreement. The Master Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name or in the name of any Servicer (to the extent permitted in the related Servicing Agreement), when the Master Servicer or a Servicer, as the case may be, believes it is appropriate in its best judgment to register any Mortgage Loan with MERS, or cause the removal from the registration of any Mortgage Loan on the MERS system, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successor and assigns. The Master Servicer shall represent and protect the interests of the Trust Fund in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan and shall not make or knowingly permit any Servicer to make any modification, waiver or amendment of any term of any Mortgage Loan that would cause an Adverse REMIC Event. Without limiting the generality of the foregoing, the Master Servicer in its own name or in the name of a Servicer, and the Servicer, to the extent such authority is delegated to such Servicer under the applicable Servicing Agreement, is hereby authorized and empowered by the Trustee when the Master Servicer or such Servicer, as the case may be, believes it appropriate in its best judgment and in accordance with Accepted Servicing Practices and the applicable Servicing Agreement, to execute and deliver, on behalf of itself and the Certificateholders, the Trustee or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to the Mortgage Loans and with respect to the Mortgaged Properties. The Trustee shall furnish to the Master Servicer, upon request, any powers of attorney empowering the Master Servicer or the Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, necessary or appropriate to enable the Master Servicer to master service the Mortgage Loans and carry out its duties hereunder and to allow such Servicer to service the Mortgage Loans, in each case in accordance with Accepted Servicing Practices (and the Trustee shall have no liability for misuse of any such powers of attorney by the Master Servicer or any Servicer). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, then upon request of the Trustee the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 6.09 hereof. In no event shall the Master Servicer, without the Trustee’s written consent: (i) initiate any action, suit or proceeding solely under the Trustee’s name without indicating the Master Servicer in its applicable, representative capacity, (ii) initiate any action, suit or proceeding not directly relating to the servicing of a Mortgage Loan (including but not limited to actions, suits or proceedings against Certificateholders, or against the Depositor, the Seller or the Transferor for breaches of representations and warranties) under the Trustee’s name, (iii) engage counsel to represent the Trustee in any action, suit or proceeding not directly relating to the servicing of a Mortgage Loan (including but not limited to actions, suits or proceedings against Certificateholders, or against the Depositor, the Seller or the Transferor for breaches of representations and warranties), or (iv) prepare, execute or deliver any government filings, forms, permits, registrations or other documents or take any action with the intent to cause, and that actually causes, the Trustee to be registered to do business in any state. The Master Servicer shall indemnify the Trustee for any and all costs, liabilities and expenses incurred by the Trustee in connection with the negligent or willful misuse of such powers of attorney by the Master Servicer. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action in the name of the Trustee on behalf of the Trust Fund, be deemed to be the agent of the Trustee.

(b)

In master servicing and administering the Mortgage Loans, the Master Servicer shall employ procedures and exercise the same care that it customarily employs and exercises in master servicing and administering loans for its own account, giving due consideration to Accepted Servicing Practices where such practices do not conflict with this Agreement. Consistent with the foregoing, the Master Servicer may, and may permit any Servicer to, in its discretion (i) waive any late payment charge (but not any Prepayment Premium, except as set forth below) and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 120 days; provided, however, that the maturity of any Mortgage Loan shall not be extended past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any extension described in clause (ii) above, the Master Servicer shall make or cause such Servicer (if required by the applicable Servicing Agreement) to make Advances on the related Mortgage Loan in accordance with the provisions of Section 5.04 on the basis of the amortization schedule of such Mortgage Loan without modification thereof by reason of such extension. Notwithstanding anything to the contrary in this Agreement, the Master Servicer shall not make or knowingly permit any modification, waiver or amendment of any material term of any Mortgage Loan, unless: (1) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the applicable Servicer, reasonably foreseeable, (2) in the case of a waiver of a Prepayment Premium, (a) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the applicable Servicer, reasonably foreseeable and such waiver would maximize recovery of total proceeds taking into account the value of such Prepayment Premium and the related Mortgage Loan or (b) if the prepayment is not the result of a refinance by the Servicer or any of its affiliates and (i) such Mortgage Loan is in default or default by the related Mortgagor is, in the reasonable judgment of the Master Servicer or the applicable Servicer, reasonably foreseeable and such waiver would maximize recovery of total proceeds taking into account the value of such Prepayment Premium and the related Mortgage Loan or (ii) the collection of the Prepayment Premium would be in violation of applicable law or (iii) the collection of such Prepayment Premium would be considered “predatory” pursuant to written guidance published or issued by any applicable federal, state or local regulatory authority acting in its official capacity and having jurisdiction over such matters and (3) the Master Servicer shall have provided or caused to be provided to the Trustee an Opinion of Counsel addressed to the Trustee (which opinion shall, if provided by the Master Servicer, be an expense reimbursed from the Collection Account pursuant to Section 4.02(v)) to the effect that such modification, waiver or amendment would not result in an Adverse REMIC Event; provided, in no event shall an Opinion of Counsel be required for the waiver of a Prepayment Premium under clause (2) above.

Section 9.05

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

(a)

Each Servicing Agreement requires the applicable Servicer, respectively, to service the Mortgage Loans in accordance with the provisions thereof. References in this Agreement to actions taken or to be taken by the Master Servicer include actions taken or to be taken by a Servicer on behalf of the Master Servicer. Any fees and other amounts payable to a Servicer shall be deducted from amounts remitted to the Master Servicer by such Servicer (to the extent permitted by the applicable Servicing Agreement) and shall not be an obligation of the Trust Fund, the Trustee or the Master Servicer.

(b)

The Master Servicer shall not be required to (i) take any action with respect to the servicing of any Mortgage Loan that the related Servicer is not required to take under the related Servicing Agreement and (ii) cause a Servicer to take any action or refrain from taking any action if the related Servicing Agreement does not require the Servicer to take such action or refrain from taking such action; in both cases notwithstanding any provision of this Agreement that requires the Master Servicer to take such action or cause the Servicer to take such action.

(c)

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

(d)

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

Section 9.06

Collection of Taxes, Assessments and Similar Items.

(a)

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

(b)

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

Section 9.07

Termination of Servicing Agreements; Successor Servicers.

(a)

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

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

(b)

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

(c)

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

Section 9.08

Master Servicer Liable for Enforcement.

Notwithstanding any Servicing Agreement, the Master Servicer shall remain obligated and liable to the Trustee and the Certificateholders in accordance with the provisions of this Agreement, to the extent of its obligations hereunder, without diminution of such obligation or liability by virtue of the Servicing Agreements. The Master Servicer shall use commercially reasonable efforts to ensure that the Mortgage Loans are serviced in accordance with the provisions of this Agreement and shall use commercially reasonable efforts to enforce the provisions of each Servicing Agreement for the benefit of the Certificateholders. The Master Servicer shall be entitled to enter into any agreement with the Servicer for indemnification of the Master Servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification. Except as expressly set forth herein, the Master Servicer shall have no liability for the acts or omissions of any Servicer in the performance by such Servicer of its obligations under the related Servicing Agreement.

Section 9.09

No Contractual Relationship Between Any Servicer and Trustee or Depositor.

Any Servicing Agreement that may be entered into and any other transactions or services relating to the Mortgage Loans involving any Servicer in its capacity as such and not as an originator shall be deemed to be between such Servicer, the Seller and the Master Servicer, and the Trustee and the Depositor shall not be deemed parties thereto and shall have no obligations, duties or liabilities with respect to such Servicer except as set forth in Section 9.10 hereof, but shall have rights thereunder as third party beneficiaries. It is furthermore understood and agreed by the parties hereto that the obligations of any Servicer are set forth in their entirety in such Servicer’s related Servicing Agreement and such Servicer has no obligations under and is not otherwise bound by the terms of this Agreement.

Section 9.10

Assumption of Servicing Agreement by Trustee.

(a)

In the event the Master Servicer shall for any reason no longer be the Master Servicer (including by reason of any Event of Default under this Agreement), after a period not to exceed ninety days after the issuance of any notice of termination pursuant to Section 6.14 or Section 9.28, as applicable, the Trustee shall, in accordance with Section 6.14, thereupon assume all of the rights and obligations of such Master Servicer hereunder and under each Servicing Agreement entered into with respect to the Mortgage Loans. The Trustee, its designee or any successor master servicer appointed by the Trustee shall be deemed to have assumed all of the Master Servicer’s interest herein and therein to the same extent as if such Servicing Agreement had been assigned to the assuming party, except that the Master Servicer shall not thereby be relieved of any liability or obligations of the Master Servicer under such Servicing Agreement accruing prior to its replacement as Master Servicer, and shall be liable to the Trustee, and hereby agrees to indemnify and hold harmless the Trustee from and against all costs, damages, expenses and liabilities (including reasonable attorneys’ fees) incurred by the Trustee as a result of such liability or obligations of the Master Servicer and in connection with the Trustee’s assumption (but not its performance, except to the extent that costs or liability of the Trustee are created or increased as a result of negligent or wrongful acts or omissions of the Master Servicer prior to its replacement as Master Servicer) of the Master Servicer’s obligations, duties or responsibilities thereunder.

(b)

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

Section 9.11

Due-on-Sale Clauses; Assumption Agreements.

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

Section 9.12

Release of Mortgage Files.

(a)

Upon (i) becoming aware of the payment in full of any Mortgage Loan or (ii) the receipt by the Master Servicer of a notification that payment in full has been or will be escrowed in a manner customary for such purposes, the Master Servicer shall, or shall cause the applicable Servicer to, promptly notify the Trustee (or the applicable Custodian) by a certification (which certification shall include a statement to the effect that all amounts received in connection with such payment that are required to be deposited in the Collection Account maintained by the Master Servicer pursuant to Section 4.01 have been or will be so deposited) of a Servicing Officer and shall request (on the form attached hereto as Exhibit C or on the form attached to the related Custodial Agreement) the Trustee or the applicable Custodian, to deliver to the applicable Servicer the related Mortgage File. Upon receipt of such certification and request, the Trustee or the applicable Custodian (with the consent, and at the direction of the Trustee), shall promptly release the related Mortgage File to the applicable Servicer and neither the Trustee nor the applicable Custodian shall have any further responsibility with regard to such Mortgage File. Upon any such payment in full, the Master Servicer is authorized, and the Servicer, to the extent such authority is provided for under the applicable Servicing Agreement, is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the Collection Account.

(b)

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

Section 9.13

Documents, Records and Funds in Possession of Master Servicer to be Held for Trustee.

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

(b)

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

(c)

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

(d)

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

In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund and the Master Servicer shall be entitled to be reimbursed therefor out of the Collection Account it maintains as provided by Section 4.02.

ARTICLE X

REMIC ADMINISTRATION

Section 10.01

REMIC Administration.

(a)

REMIC elections as set forth in the Preliminary Statement shall be made on Forms 1066 or other appropriate federal tax or information return for the taxable year ending on the last day of the calendar year in which the Certificates are issued. The regular interests and residual interest in each REMIC shall be as designated in the Preliminary Statement. For purposes of such designations, the interest rate of any regular interest that is computed by taking into account the weighted average of the Net Mortgage Rates of the Mortgage Loans in any Pool shall be reduced by the amount of any expense paid by the Trust and allocable to such Pool to the extent that (i) such expense was not taken into account in computing the Net Mortgage Rate of any Mortgage Loan, (ii) such expense does not constitute an “unanticipated expense” of a REMIC within the meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii) and (iii) the amount of such expense was not taken into account in computing the interest rate of a more junior class of regular interests.

(b)

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

(c)

The Trustee shall represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto. The Trustee shall pay any and all tax related expenses (not including taxes) of each REMIC, including but not limited to any professional fees or expenses related to audits or any administrative or judicial proceedings with respect to such REMIC that involve the Internal Revenue Service or state tax authorities, but only to the extent that (i) such expenses are ordinary or routine expenses, including expenses of a routine audit but not expenses of litigation (except as described in (ii)); or (ii) such expenses or liabilities (including taxes and penalties) are attributable to the negligence or willful misconduct of the Trustee in fulfilling its duties hereunder (including its duties as tax return preparer). The Trustee shall be entitled to reimbursement of expenses to the extent provided in clause (i) above from the Certificate Account, provided, however, the Trustee shall not be entitled to reimbursement for expenses incurred in connection with the preparation of tax returns and other reports as required by Section 6.20 and this Section.

(d)

The Trustee shall prepare, the Trustee shall sign, and the Trustee will file, all of each REMIC’s federal and applicable state tax and information returns as such REMIC’s direct representative. As used herein, applicable state tax and information returns shall mean returns as may be required by the laws of any state the applicability of which to the Trust Fund shall have been confirmed to the Trustee in writing either by the delivery to the Trustee of an Opinion of Counsel to such effect, or by delivery to the Trustee of a written notification to such effect by the taxing authority of such state. The expenses of preparing and filing such returns shall be borne by the Trustee.

(e)

The Trustee or its designee shall perform on behalf of each REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions, or other compliance guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, if required by the Code, the REMIC Provisions, or other such guidance, the Trustee shall provide (i) to the Treasury or other governmental authority such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any disqualified person or organization pursuant to Treasury Regulation 1.860E-2(a)(5) and any person designated in Section 860E(e)(3) of the Code and (ii) to the Certificateholders such information or reports as are required by the Code or REMIC Provisions.

The Trustee shall be entitled to receive reasonable compensation from the Trust Fund for the performance of its duties under this subsection (e); provided, however, that such compensation shall not exceed $5,000 per year; provided, further, that after a Section 7.01(c) Purchase Event, any expenses incurred by the Trustee in connection with such Section 7.01(c) Purchase Event shall be reimbursed to the Trustee, regardless of the limitation set forth above, in accordance with Section 4.04(b).

(f)

The Trustee, the Master Servicer and the Holders of Certificates shall take any action, within their respective control and scope of duties, or cause any REMIC to take any action necessary to create or maintain the status of any REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. None of the Trustee, the Master Servicer or the Holder of any Residual Certificate shall knowingly take any action, within its respective control, cause any REMIC to take any action or fail to take (or fail to cause to be taken) any action within its respective control and scope of duties, that, under the REMIC Provisions, if taken or not taken, as the case may be, could result in an Adverse REMIC Event unless the Trustee and the Master Servicer have received an Opinion of Counsel addressed to the Trustee (at the expense of the party seeking to take such action) to the effect that the contemplated action will not result in an Adverse REMIC Event. In addition, prior to taking any action with respect to any REMIC or the assets therein, or causing any REMIC to take any action, which is not expressly permitted under the terms of this Agreement, any Holder of a Residual Certificate will consult with the Trustee, the Master Servicer or their respective designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall take any such action or cause any REMIC to take any such action as to which the Trustee or the Master Servicer has advised it in writing that an Adverse REMIC Event could occur.

(g)

Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on the related REMIC by federal or state governmental authorities. To the extent that such taxes are not paid by a Residual Certificateholder, the Trustee shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Residual Certificate in any such REMIC or, if no such amounts are available, out of other amounts held in the Collection Account, and shall reduce amounts otherwise payable to holders of regular interests in any such REMIC, as the case may be.

(h)

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

(i)

No additional contributions of assets shall be made to any REMIC, except as expressly provided in this Agreement.

(j)

Neither the Trustee nor the Master Servicer shall enter into any arrangement by which any REMIC will receive a fee or other compensation for services.

(k)

[Reserved]

(l)

The Trustee shall treat each of the Basis Risk Reserve Fund and the Supplemental Interest Trust Account as an outside reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h) that is owned by the Holders of the Class M2 Certificates and that is not an asset of any REMIC and all amounts deposited into the Basis Risk Reserve Fund or the Supplemental Interest Trust Account shall be treated as amounts distributed to the Class M2 Certificateholders.

(m)

[Reserved]

(n)

The Trustee shall treat the beneficial owners of Certificates (other than the Class M2, Class P, Class X, Class LT-R and Class R Certificates) as having entered into a notional principal contract with respect to the beneficial owners of the Class M2 Certificates. Pursuant to each such notional principal contract, all beneficial owners of the Publicly Offered Certificates and the Class B1, Class B2, Class B3 and Class B4 Certificates shall be treated as having agreed to pay, on each Distribution Date, to the beneficial owners of the Class M2 Certificates an aggregate amount equal to the excess, if any, of (i) the amount payable on such Distribution Date on the interest in REMIC 5 corresponding to such Class of Certificates over (ii) the amount payable on such Class of Certificates on such Distribution Date (such excess, a “Class I Shortfall”). A Class I Shortfall payable from interest collections shall be allocated to each Class of Certificates to the extent that interest accrued on such Class for the related Accrual Period at the Certificate Interest Rate for a Class, computed by substituting “REMIC 4 Net Funds Cap” for “Net Funds Cap” in the definition thereof, exceeds the amount of interest accrued for the related Accrual Period based on the Net Funds Cap, and a Class I Shortfall payable from principal collections shall be allocated to the most subordinate Class of Certificates with an outstanding principal balance to the extent of such balance. In addition, pursuant to such notional principal contract, the beneficial owner of the Class M2 Certificates shall be treated as having agreed to pay Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls to the Owners of the Publicly Offered Certificates and the Class B1, Class B2, Class B3 and Class B4 Certificates in accordance with the terms of this Agreement. Any payments to the Certificates in light of the foregoing shall not be payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1). However, any payment from the Certificates of a Class I Shortfall shall be treated for tax purposes as having been received by the beneficial owners of such Certificates in respect of their interests in REMIC 5 and as having been paid by such beneficial owners to the Supplemental Interest Trust pursuant to the notional principal contract. Thus, each Certificate (other than a Class P, Class R and Class LT-R Certificate) shall be treated as representing not only ownership of regular interests in REMIC 5, but also ownership of an interest in (and obligations with respect to) a notional principal contract. For tax purposes, the notional principal contract shall be deemed to have a value in favor of the Certificates entitled to receive Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls of $32,810.77 as of the Closing Date.

(o)

Notwithstanding the priority and sources of payments set forth in Article V hereof or otherwise, the Trustee shall account for all distributions on the Certificates as set forth in this Section 10.01. In no event shall any payments of Basis Risk Shortfalls or Unpaid Basis Risk Shortfalls provided for in this Section 10.01 be treated as payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1).

Section 10.02

Prohibited Transactions and Activities.

Neither the Depositor, the Master Servicer nor the Trustee shall sell, dispose of, or substitute for any of the Mortgage Loans, except in a disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund, (iii) the termination of each REMIC pursuant to Article VII of this Agreement, (iv) a substitution pursuant to Article II of this Agreement or (v) a repurchase of Mortgage Loans pursuant to Article II of this Agreement, nor acquire any assets for any REMIC, nor sell or dispose of any investments in the Certificate Account for gain, nor accept any contributions to any REMIC after the Closing Date, unless the Trustee has received an Opinion of Counsel addressed to the Trustee (at the expense of the party causing such sale, disposition, or substitution) that such disposition, acquisition, substitution, or acceptance will not (a) result in an Adverse REMIC Event, (b) affect the distribution of interest or principal on the Certificates or (c) result in the encumbrance of the assets transferred or assigned to the Trust Fund (except pursuant to the provisions of this Agreement).

Section 10.03

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

Upon the occurrence of an Adverse REMIC Event due to the negligent performance by the Trustee of its duties and obligations set forth herein, the Trustee shall indemnify the Holder of the related Residual Certificate or the Trust Fund, as applicable, against any and all losses, claims, damages, liabilities or expenses (“Losses”) resulting from such negligence; provided, however, that the Trustee shall not be liable for any such Losses attributable to the action or inaction of the Master Servicer, the Depositor, the Class X Certificateholders, 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 on which the Trustee has relied. The foregoing shall not be deemed to limit or restrict the rights and remedies of the Holder of such Residual Certificate now or hereafter existing at law or in equity. Notwithstanding the foregoing, however, in no event shall the Trustee have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement or the Servicing Agreement, (2) for any Losses other than arising out of a negligent performance by the Trustee of its duties and obligations set forth herein, and (3) for any special or consequential damages to Certificateholders (in addition to payment of principal and interest on the Certificates) even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. In addition, the Trustee shall not have any liability for the actions or failure to act of any other party hereto.

Section 10.04

REO Property.

(a)

Notwithstanding any other provision of this Agreement, the Master Servicer, acting on behalf of the Trustee hereunder, shall not, except to the extent provided in the applicable Servicing Agreement, knowingly permit any Servicer to, rent, lease, or otherwise earn income on behalf of any REMIC with respect to any REO Property which might cause an Adverse REMIC Event unless the Master Servicer has advised, or has caused the applicable Servicer to advise and the Trustee in writing to the effect that, under the REMIC Provisions, such action would not result in an Adverse REMIC Event.

(b)

The Master Servicer shall cause the applicable Servicer (to the extent provided in its Servicing Agreement) to make reasonable efforts to sell any REO Property for its fair market value. In any event, however, the Master Servicer shall, or shall cause the applicable Servicer (to the extent provided in its Servicing Agreement) to, dispose of any REO Property within three years of its acquisition by the Trust Fund unless the Master Servicer has received a grant of extension from the Internal Revenue Service to the effect that, under the REMIC Provisions, the REMIC may hold REO Property for a longer period without causing an Adverse REMIC Event. If the Master Servicer has received such an extension, then the Master Servicer, acting on the Trustee’s behalf hereunder, shall, or shall cause the applicable Servicer to, continue to attempt to sell the REO Property for its fair market value for such period longer than three years as such extension permits (the “Extended Period”). If the Master Servicer has not received such an extension and the Master Servicer or the applicable Servicer, acting on behalf of the Trustee hereunder, is unable to sell the REO Property within 33 months after its acquisition by the Trust Fund or if the Master Servicer has received such an extension, and the Master Servicer or the applicable Servicer is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Master Servicer shall cause the applicable Servicer, before the end of the three year period or the Extended Period, as applicable, to (i) purchase such REO Property at a price equal to the REO Property’s fair market value or (ii) auction the REO Property to the highest bidder (which may be the applicable 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.

SELLER’S ENGAGEMENT OF SERVICER TO PERFORM SERVICING RESPONSIBILITIES

Section 2.1

Contract for Servicing; Possession of Servicing Files.

The Seller, by execution and delivery of this Agreement, does hereby contract with the Servicer as an independent contractor, subject to the terms of this Agreement, for the servicing of the Mortgage Loans. On or before the Servicing Transfer Date, the Seller shall cause to be delivered the Servicing Files with respect to the Mortgage Loans listed on the Mortgage Loan Schedule to the Servicer if the Servicer does not already hold such Servicing Files. The Servicer shall maintain a Servicing File with respect to each Mortgage Loan in order to service such Mortgage Loans pursuant to this Agreement and Accepted Servicing Practices and each Servicing File delivered to the Servicer shall be held in trust by the Servicer for the benefit of the Trustee; 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 Mortgage Loan documents shall be at the will of the Trustee for the sole purpose of facilitating servicing of the related Mortgage 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 Trustee and the ownership of all records and documents with respect to the related Mortgage Loan prepared by or which come into the possession of the Servicer shall immediately vest in the Trustee and shall be retained and maintained, in trust, by the Servicer at the will of the Trustee in such custodial capacity only. Upon Servicer’s reasonable request, Seller shall assist the Servicer in all reasonable respects in Servicer’s efforts to obtain any additional documentation or information to be included in the Servicing File to enable Servicer to service the Mortgage Loans properly. The Seller shall be responsible for all fees and expenses of the Custodians, including reasonable fees and expenses due to Servicer’s requests of the Custodians in the normal course of Servicer’s collection and foreclosure activities (including but not limited to follow-up document deliveries of the Servicer, photocopies of documents made at the request of the Servicer and follow-up document insertion fees).

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 Mortgage Loan by the Trustee. The Servicer shall release from its custody the contents of any Servicing File retained by it only in accordance with this Agreement.

Section 2.2

Books and Records.

(a)

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

(b)

The Servicer shall forward to the related Custodian original documents evidencing an assumption, modification, consolidation or extension of any Mortgage Loan entered into in accordance with Section 3.01 within ten (10) days of their execution; provided, however, that the Servicer shall provide such Custodian with a Servicer certified true copy of any such document submitted for recordation within ten (10) days of its execution, and shall provide the original of any document submitted for recordation or a copy of such document certified by the appropriate public recording office to be a true and complete copy of the original within 120 days of its submission for recordation, or as soon thereafter as such recording office will make such certified copy available.

ARTICLE III

SERVICING OF THE MORTGAGE LOANS

Section 3.1

Servicer to Service.

The Servicer, as an independent contractor, shall service and administer the Mortgage Loans from and after the Servicing Transfer 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 shall not have any liability or obligation with respect to the Mortgage Loans or this Agreement arising prior to the Servicing Transfer Date.

Consistent with the terms of this Agreement, the Servicer may waive, modify or vary any term of any Mortgage Loan or consent to the postponement of strict compliance with any such term or in any manner grant indulgence to any Mortgagor if in the Servicer’s reasonable and prudent determination and in accordance with Accepted Servicing Practices such waiver, modification, postponement or indulgence is not materially adverse to the Trust Fund; provided, however, that unless the Servicer has obtained the prior written consent of the Master Servicer and the NIMS Insurer, the Servicer shall not permit any modification with respect to any Mortgage Loan that would change the Mortgage Interest Rate (except for modifications relating to a Relief Act Reduction), forgive the payment of principal or interest or reduce or increase the outstanding principal balance (except for actual payments of principal) or change the final maturity date on such Mortgage Loan. In the event of any such modification which permits the deferral of interest or principal payments on any Mortgage 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 Mortgage Loan Remittance Rate on the unpaid principal balance of such Mortgage 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 3.04. 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 Trustee, all instruments of satisfaction or cancellation, or of partial or full release, discharge and all other comparable instruments, with respect to the Mortgage Loans and with respect to the Mortgaged Properties; provided, further, that upon the full release or discharge, the Servicer shall notify the related Custodian of the related Mortgage Loan of such full release or discharge. Upon the reasonable request of the Servicer, the Trustee shall execute and deliver to the Servicer with any powers of attorney 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; provided that the Trustee shall not be liable for the actions of the Servicer under such powers of attorney. Promptly after the execution of any assumption, modification, consolidation or extension of any Mortgage Loan, the Servicer shall forward to the Master Servicer copies of any documents evidencing such assumption, modification, consolidation or extension. Notwithstanding anything to the contrary contained in this Agreement, the Servicer shall not make or permit any modification, waiver or amendment of any term of any Mortgage Loan that would cause any REMIC created under the Trust Agreement to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code. Notwithstanding anything to the contrary contained in this Agreement, the Servicer shall not take any action that may cause the Master Servicer to violate Section 9.04 of the Trust Agreement.

The Servicer is authorized, without the prior approval of the Master Servicer or the Seller, to consent to the refinancing of any Superior Lien on Mortgaged Property, provided that (i) the resulting Combined Loan-to-Value Ratio of such Mortgage Loan is no higher than the Combined Loan-to-Value Ratio prior to such refinancing; (ii) the Mortgage Interest Rate, or in the case of any Superior Lien which is an adjustable rate mortgage loan, the applicable maximum rate which can be charged under the related Mortgage Note is no more than 2.00% higher than the interest rate on the loan evidencing the existing Superior Lien immediately prior to the date of such refinancing; and (iii) the mortgage loan evidencing the Superior Lien is not subject to negative amortization.

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

In servicing and administering the Mortgage Loans, the Servicer shall employ procedures (including collection procedures) and exercise the same care that it would employ and exercise in servicing and administering similar mortgage loans held for its own account, giving due consideration to Accepted Servicing Practices where such practices do not conflict with the requirements of this Agreement. In connection with a Principal Prepayment in which the Mortgage Note provides for the ability to collect a Prepayment Charge, the Servicer shall use Accepted Servicing Practices to verify whether a Prepayment Charge is due for the related Mortgage Loan. Upon request, the Servicer shall promptly provide the Master Servicer with documentation regarding such verification.

The parties to this Agreement acknowledge that Servicing Advances shall be reimbursable pursuant to Section 3.04 of this Agreement and agree that no Servicing Advance shall be rejected or disallowed by any party unless it has been shown that such Servicing Advance was not made in accordance with the terms of this Agreement, including, but not limited to, the failure to (i) provide all appropriate documentation relating to such Servicing Advance and (ii) act in accordance with Section 3.04.

Section 3.2

Collection of Mortgage Loan Payments.

Continuously from the Closing Date or Servicing Transfer Date, as applicable, until the date each Mortgage Loan ceases to be subject to this Agreement, the Servicer shall proceed diligently to collect all payments due under each of the Mortgage 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 Mortgage 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. The Servicer shall also apply payments of interest and principal against any Simple Interest Mortgage Loans using the Simple Interest Method.

Section 3.3

Establishment of and Deposits to Custodial Account.

The Servicer shall segregate and hold all funds collected and received pursuant to the Mortgage Loans separate and apart from any of its own funds and general assets and shall establish and maintain one or more Custodial Accounts, in the form of time deposit or demand accounts, titled “Ocwen Loan Servicing, LLC in trust for Citibank, N.A., as Trustee for the Structured Asset Securities Corporation Mortgage Loan Trust, 2006-S2.” The Custodial Account shall be an Eligible Deposit Account established with an Eligible Institution. Any funds deposited in the Custodial Account may be invested in Eligible Investments subject to the provisions of Section 3.09 hereof.

Not later than 30 days after the Closing Date, a copy of such certification or letter agreement shall be furnished to the Master Servicer and the NIMS Insurer.

The Servicer shall deposit in the Custodial Account on a daily basis on or prior to the second Business Day following receipt thereof, and retain therein, the following collections received by the Servicer and payments made by the Servicer after the Cut-off Date (other than scheduled payments of principal and interest due on or before the Cut-off Date) or the Servicing Transfer Date, as applicable:

The Servicer shall also deposit from its own funds into the Custodial Account, without the right to reimbursement, except from Net Simple Interest Excess, an amount equal to any Net Simple Interest Shortfall (to the extent not offset by Net Simple Interest Excess) for the related Due Period and remit such funds to the Master Servicer pursuant to Section 4.01.

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 the Servicing Fee and Ancillary Income need not be deposited by the Servicer into the Custodial Account; provided, however, that the Servicer may not withhold from deposit into the Custodial Account any funds relating to claims of reimbursement for any Monthly Advances, Servicing Advances, fees, expenses or other costs eligible for reimbursement under this Agreement. Any interest paid on funds deposited in the Custodial Account by the depository institution shall accrue to the benefit of the Servicer and the Servicer shall be entitled to retain and withdraw such interest from the Custodial Account pursuant to Section 3.04.

Amounts on deposit in the Custodial Account may at the option of the Servicer be invested in Eligible Investments. Any such Eligible Investment shall mature no later than one day prior to the Remittance Date in each month; provided, however, that if such Eligible Investment is an obligation of an Eligible Institution (other than the Servicer) that maintains the Custodial Account, then such Eligible Investment may mature on the related Remittance Date. Any such Eligible Investment shall be made in the name of the Servicer in trust for the benefit of the Trustee. 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, by the Servicer out of its own funds immediately as realized. If, at any time, the amount on deposit in the Custodial Account exceeds the amount of the applicable FDIC insurance, such excess above the amount of the applicable FDIC insurance shall be invested in Eligible Investments.

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. Any such Eligible Investment shall be made in the name of the Servicer in trust for the benefit of the Trustee. 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 3.10

Maintenance of Hazard Insurance.

The Servicer shall, to the extent it is notified or discovers that hazard insurance has not been maintained for a Mortgage Loan, or if all obligations of a Mortgagor have been satisfied with respect to each Superior Lien related to a Mortgage Loan, cause to be maintained for such Mortgage Loan hazard insurance such that all buildings upon the Mortgaged Property are insured by a generally acceptable insurer acceptable under ▇▇▇▇▇▇ ▇▇▇ and ▇▇▇▇▇▇▇ Mac guidelines against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located, in an amount which is at least equal to the lesser of (i) the replacement value of the improvements securing such Mortgage Loan and (ii) the greater of (a) the outstanding principal balance of the Mortgage Loan and (b) an amount such that the proceeds thereof shall be sufficient to prevent the Mortgagor or the loss payee from becoming a co-insurer.

If upon origination of the Mortgage Loan, the related Mortgaged Property was located in an area identified in the Federal Register by the Flood Emergency Management Agency as having special flood hazards (and such flood insurance has been made available) a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration is in effect with a generally acceptable insurance carrier rated A:VI or better in the current edition of Best’s Key Rating Guide in an amount representing coverage equal to the lesser of (i) the minimum amount required, under the terms of coverage, to compensate for any damage or loss on a replacement cost basis (or the unpaid balance of the mortgage if replacement cost coverage is not available for the type of building insured) and (ii) the maximum amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended. If at any time during the term of the Mortgage Loan, the Servicer determines in accordance with applicable law and pursuant to the ▇▇▇▇▇▇ Mae Guides that a Mortgaged Property is located in a special flood hazard area and is not covered by flood insurance or is covered in an amount less than the amount required by the Flood Disaster Protection Act of 1973, as amended, the Servicer shall notify the related Mortgagor that the Mortgagor must obtain such flood insurance coverage, and if said Mortgagor fails to obtain the required flood insurance coverage within thirty (30) days after such notification and the holder of the Superior Lien fails to require or force place the required flood insurance under this Section 3.10, the Servicer shall immediately force place the required flood insurance on the Mortgagor’s behalf.

If a Mortgage is secured by a unit in a condominium project, the Servicer shall verify that the coverage required of the owner’s association, including hazard, flood, liability, and fidelity coverage, is being maintained in accordance with then current ▇▇▇▇▇▇ ▇▇▇ requirements, and secure from the owner’s association its agreement to notify the Servicer promptly of any change in the insurance coverage or of any condemnation or casualty loss that may have a material effect on the value of the Mortgaged Property as security.

The Servicer shall cause to be maintained on each Mortgaged Property earthquake or such other or additional insurance as may be required pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance, or pursuant to the requirements of any private mortgage guaranty insurer, or as may be required to conform with Accepted Servicing Practices.

In the event that the Servicer shall determine that the Mortgaged Property should be insured against loss or damage by hazards and risks not covered by the insurance required to be maintained by the Mortgagor pursuant to the terms of the Mortgage, the Servicer shall communicate and consult with the Mortgagor with respect to the need for such insurance and bring to the Mortgagor’s attention the desirability of protection of the Mortgaged Property.

All policies required hereunder shall name the Servicer as loss payee and shall be endorsed with standard or union mortgagee clauses, without contribution, which shall provide for at least 30 days prior written notice of any cancellation, reduction in amount or material change in coverage.

The Servicer shall not interfere with the Mortgagor’s freedom of choice in selecting either his insurance carrier or agent, provided, however, that the Servicer shall not accept any such insurance policies from insurance companies unless such companies are rated A:VI or better in Best’s Key Rating Guide or are acceptable to ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac and are licensed to do business in the jurisdiction in which the Mortgaged Property is located. The Servicer shall determine that such policies provide sufficient risk coverage and amounts, that they insure the property owner, and that they properly describe the property address. The Servicer shall furnish to the Mortgagor a formal notice of expiration of any such insurance in sufficient time for the Mortgagor to arrange for renewal coverage by the expiration date.

Pursuant to Section 3.04, any amounts collected by the Servicer under any such policies (other than amounts to be deposited in the Escrow Account and applied to the restoration or repair of the related Mortgaged Property, or property acquired in liquidation of the Mortgage Loan, or to be released to the Mortgagor, in accordance with the Servicer’s normal servicing procedures as specified in Section 3.14) shall be deposited in the Custodial Account subject to withdrawal pursuant to Section 3.04.

Section 3.11

Maintenance of Mortgage Impairment Insurance.

In the event that the Servicer shall obtain and maintain a blanket policy insuring against losses arising from fire and hazards covered under extended coverage on all of the Mortgage Loans, then, to the extent such policy provides coverage in an amount equal to the amount required pursuant to Section 3.10 and otherwise complies with all other requirements of Section 3.10, it shall conclusively be deemed to have satisfied its obligations as set forth in Section 3.10. Any amounts collected by the Servicer under any such policy relating to a Mortgage Loan shall be deposited in the Custodial Account subject to withdrawal pursuant to Section 3.05. Such policy may contain a deductible clause, in which case, in the event that there shall not have been maintained on the related Mortgaged Property a policy complying with Section 3.10, and there shall have been a loss which would have been covered by such policy, the Servicer shall deposit in the Custodial Account at the time of such loss the amount not otherwise payable under the blanket policy because of such deductible clause, such amount to deposited from the Servicer’s funds, without reimbursement therefor. Upon request of the Master Servicer or the NIMS Insurer, the Servicer shall cause to be delivered to such party a certified true copy of such policy and a statement from the insurer thereunder that such policy shall in no event be terminated or materially modified without 30 days’ prior written notice to the Master Servicer or the NIMS Insurer.

Section 3.12

Maintenance of Fidelity Bond and Errors and Omissions Insurance.

The Servicer shall maintain with responsible companies, at its own expense, a blanket Fidelity Bond and an Errors and Omissions Insurance Policy, with broad coverage on all officers, employees or other persons acting in any capacity requiring such persons to handle funds, money, documents or papers relating to the Mortgage Loans (“Servicer Employees”). Any such Fidelity Bond and Errors and Omissions Insurance Policy shall be in the form of the Mortgage Banker’s Blanket Bond and shall protect and insure the Servicer against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of such Servicer Employees. Such Fidelity Bond and Errors and Omissions Insurance Policy also shall protect and insure the Servicer against losses in connection with the release or satisfaction of a Mortgage Loan without having obtained payment in full of the indebtedness secured thereby. No provision of this Section 3.12 requiring such Fidelity Bond and Errors and Omissions Insurance Policy shall diminish or relieve the Servicer from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by ▇▇▇▇▇▇ ▇▇▇ in the ▇▇▇▇▇▇ Mae Guides or by ▇▇▇▇▇▇▇ Mac in the ▇▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇’ & Servicers’ Guide. Upon the request of the Master Servicer or the NIMS Insurer, the Servicer shall cause to be delivered to such party a certified true copy of such Fidelity Bond and Errors and Omissions Insurance Policy and a statement from the surety and the insurer that such Fidelity Bond and Errors and Omissions Insurance Policy shall in no event be terminated or materially modified without 30 days’ prior written notice to the Master Servicer or the NIMS Insurer.

Section 3.13

Inspections.

The Servicer shall inspect the Mortgaged Property as often as deemed necessary by the Servicer in accordance with Accepted Servicing Practices to assure itself that the value of the Mortgaged Property is being preserved. In addition, if any Mortgage Loan is more than 60 days delinquent, the Servicer shall inspect the Mortgaged Property in accordance with Accepted Servicing Practices and shall conduct subsequent inspections in accordance with Accepted Servicing Practices or as may be required by the primary mortgage guaranty insurer. The Servicer shall keep a written report of each such inspection.

Section 3.14

Restoration of Mortgaged Property.

The Servicer need not obtain the approval of the Master Servicer or the Trustee prior to releasing any Insurance Proceeds or Condemnation Proceeds to the Mortgagor to be applied to the restoration or repair of the Mortgaged Property if such release is in accordance with Accepted Servicing Practices. At a minimum, the Servicer shall comply with the following conditions in connection with any such release of Insurance Proceeds or Condemnation Proceeds:

(i)

the Servicer shall receive satisfactory independent verification of completion of repairs and issuance of any required approvals with respect thereto;

(ii)

the Servicer shall take all steps necessary to preserve the priority of the lien of the Mortgage, including, but not limited to requiring waivers with respect to mechanics’ and materialmen’s liens;

(iii)

the Servicer shall verify that the Mortgage Loan is not sixty (60) or more days delinquent; and

(iv)

pending repairs or restoration, the Servicer shall place the Insurance Proceeds or Condemnation Proceeds in the Escrow Account.

Section 3.15

Maintenance of PMI Policy and/or LPMI Policy; Claims.

(a)

The Servicer shall comply with all provisions of applicable state and federal law relating to the cancellation of, or collection of premiums with respect to, PMI Policies, including, but not limited to, the provisions of the Homeowners Protection Act of 1998, and all regulations promulgated thereunder, as amended from time to time. The Servicer shall be obligated to make premium payments with respect to (i) LPMI Policies, to the extent that the Servicer has been advised in writing by the Master Servicer or the Depositor of its obligation to make such payments, which shall be paid out of the interest portion of the related Monthly Payment or, if a Monthly Payment is not made, from the Servicer’s own funds and (ii) PMI Policies required to be maintained by the Mortgagor, if the Mortgagor is required but fails to pay any PMI Policy premium, which shall be paid from the Servicer’s own funds. Any premium payments made by the Servicer from its own funds pursuant to this Section 3.15(a) shall be recoverable by the Servicer as a Servicing Advance, subject to the reimbursement provisions of Sections 3.04(iii) and 3.04(iv).

With respect to each Mortgage Loan (other than LPMI Loans) with an LTV Ratio at origination in excess of 80%, the Servicer shall maintain or cause the Mortgagor to maintain (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance) in full force and effect a PMI Policy, and shall pay or shall cause the Mortgagor to pay the premium thereon on a timely basis, until the LTV Ratio of such Mortgage Loan is reduced to 80%. In the event that such PMI Policy shall be terminated, the Servicer shall obtain from another Qualified Insurer a comparable replacement policy, with a total coverage equal to the remaining coverage of such terminated PMI Policy, at substantially the same fee level. The Servicer shall not take any action which would result in noncoverage under any applicable PMI Policy of any loss which, but for the actions of the Servicer would have been covered thereunder. In connection with any assumption or substitution agreements entered into or to be entered into with respect to a Mortgage Loan, the Servicer shall promptly notify the insurer under the related PMI Policy, if any, of such assumption or substitution of liability in accordance with the terms of such PMI Policy and shall take all actions which may be required by such insurer as a condition to the continuation of coverage under such PMI Policy. If such PMI Policy is terminated as a result of such assumption or substitution of liability, the Servicer shall obtain a replacement PMI Policy as provided above.

(b)

With respect to each Mortgage Loan covered by a PMI Policy or LPMI Policy, the Servicer shall take all such actions on behalf of the Trustee as are necessary to service, maintain and administer the related Mortgage Loan in accordance with such Policy and to enforce the rights under such Policy. Except as expressly set forth herein, the Servicer shall have full authority on behalf of the Trust Fund to do anything it deems appropriate or desirable in connection with the servicing, maintenance and administration of such Policy; provided that the Servicer shall not take any action to permit any modification or assumption of a Mortgage Loan covered by a LPMI or PMI Policy, or take any other action with respect to such Mortgage Loan which would result in non-coverage under such Policy of any loss which, but for actions of any Servicer or the Subservicer, would have been covered thereunder. If the Qualified Insurer fails to pay a claim under a LPMI or PMI Policy solely as a result of a breach by the Servicer or Subservicer of its obligations hereunder or under such 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 rights to reimbursement from the Trust Fund. The Servicer shall cooperate with the Qualified Insurers and shall furnish all reasonable evidence and information in the possession of the Servicer to which the Servicer has access with respect to the related Mortgage Loan; provided, however, that notwithstanding anything to the contrary contained in any LPMI Policy or PMI Policy, the Servicer shall not be required to submit any reports to the related Qualified 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 systems in accordance with the Qualified Insurer’s requirements.

(c)

In connection with its activities as servicer, the Servicer agrees to prepare and present, on behalf of itself and the Trustee, claims to the Qualified Insurer under any PMI Policy or LPMI Policy in a timely fashion in accordance with the terms of such PMI Policy or LPMI Policy and, in this regard, to take such action as shall be necessary to permit recovery under any PMI Policy or LPMI Policy respecting a defaulted Mortgage Loan. Any amounts collected by the Servicer under any PMI Policy or LPMI Policy shall be deposited in the Custodial Account pursuant to Section 3.03(xiv), subject to withdrawal pursuant to Section 3.04.

(d)

The Trustee shall furnish the Servicer with any powers of attorney and other documents (within three (3) Business 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 or LPMI Policy; provided, however, that the Trustee shall not be liable for the actions of the Servicer under such power of attorney.

(e)

The Servicer shall deposit into the Custodial Account pursuant to Section 3.03(v) hereof all Insurance Proceeds received under the terms of a PMI Policy or an LPMI Policy.

(f)

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

Section 3.16

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 Trustee or its nominee in trust for the benefit of the Certificateholders, or in the event the Trustee 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 (with a copy delivered to the Trustee) 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 Trustee shall acknowledge in writing that such title is being held as nominee for the Trustee.

The Servicer shall manage, conserve, protect and operate each REO Property for the Trustee 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 the 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 Trustee and the Certificateholders.

If the Servicer hereafter becomes aware that a Mortgaged Property is an Environmental Problem Property, the Servicer will notify the Master Servicer, the Trustee and the NIMS Insurer of the existence of the Environmental Problem Property. Additionally, the Servicer shall set forth in such notice a description of such problem, a recommendation to the Master Servicer and the NIMS Insurer relating to the proposed action regarding the Environmental Problem Property, and the Servicer shall carry out the recommendation set forth in such notice unless otherwise directed by the NIMS Insurer in writing within five (5) days after its receipt (or deemed receipt) of such notice in accordance with the terms and provisions of Section 9.04 below. The Master Servicer and the Trustee shall be provided a copy of the NIMS Insurer’s instructions to the Servicer. Notwithstanding the foregoing, the Servicer shall obtain the Master Servicer’s and the NIMS Insurer’s written consent to any expenditures proposed to remediate Environmental Problem Properties or to defend any claims associated with Environmental Problem Properties if such expenses, in the aggregate, are expected to exceed $100,000. Failure to provide written notice of disapproval of the expenditure within five (5) days of receipt (or deemed receipt) of such request for prepaid expenditures shall be deemed an approval of such expenditure. The Master Servicer shall be provided with a copy of the NIMS Insurer’s instructions to the Servicer. If the Servicer has received reliable instructions to the effect that a Property is an Environmental Problem Property (e.g., Servicer obtains a broker’s price opinion which reveals the potential for such problem), the Servicer will not accept a deed-in-lieu of foreclosure upon any such Property without first obtaining a preliminary environmental investigation for the Property satisfactory to the NIMS Insurer.

In the event that the Trust Fund acquires any REO Property in connection with a default or imminent default on a Mortgage 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 Trust Fund unless the Servicer has applied for and received a grant of extension from the Internal Revenue Service (and provide a copy of the same to the NIMS Insurer and the Trustee) to the effect that, under the REMIC Provisions and any relevant proposed legislation and under applicable state law, the applicable Trust REMIC 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 NIMS Insurer), 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 three months before the end of such third taxable year after its acquisition by the Trust Fund 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, as acceptable to the NIMS Insurer 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 Trustee shall sign any document or take any other action reasonably requested by the Servicer which would enable the Servicer, on behalf of the Trust Fund, to request such grant of extension.

Notwithstanding any other provisions of this Agreement, no REO Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used by or on behalf of the Trust Fund 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 Trust REMIC 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 the Trust Fund and the NIMS Insurer with respect to the imposition of any such taxes.

The Servicer shall also maintain on each REO Property fire and hazard insurance with extended coverage in amount which is at least equal to the maximum insurable value of the improvements which are a part of such property, liability insurance and, to the extent required and available under the Flood Disaster Protection Act of 1973, as amended, flood insurance in the amount required above.

The proceeds of sale of the REO Property shall be promptly deposited in the Custodial Account. As soon as practical thereafter the expenses of such sale shall be paid and the Servicer shall reimburse itself for any related unreimbursed Servicing Advances, unpaid Servicing Fees and unreimbursed advances made pursuant to this Section or Section 4.03.

The Servicer shall make advances of all funds necessary for the proper operation, management and maintenance of the REO Property, including the cost of maintaining any hazard insurance pursuant to Section 3.10, such advances to be reimbursed from the disposition or liquidation proceeds of the REO Property. 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 3.16 and of any reserves reasonably required from time to time to be maintained to satisfy anticipated liabilities for such expenses).

Section 3.17

Real Estate Owned Reports.

Together with the statement furnished pursuant to Section 4.02, the Servicer shall furnish to the Master Servicer, the Credit Risk Manager and the NIMS Insurer on or before the Remittance Date in each month a statement with respect to any REO Property covering the operation of such REO Property for the previous month and, if requested, 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 either the Master Servicer, the Credit Risk Manager or the NIMS Insurer shall reasonably request.

Section 3.18

Liquidation Reports.

Upon the foreclosure sale of any Mortgaged Property or the acquisition thereof by the Servicer on behalf of the Trustee pursuant to a deed in lieu of foreclosure, the Servicer shall submit to the Master Servicer a liquidation report with respect to such Mortgaged Property.

Section 3.19

Reports of Foreclosures and Abandonments of Mortgaged Property.

Following the foreclosure sale or abandonment of any Mortgaged Property, the Servicer shall report such foreclosure or abandonment as required pursuant to Section 6050J of the Code.

Section 3.20

Prepayment Charges.

Except as provided below, the Servicer or any designee of the Servicer shall not waive any Prepayment Charge with respect to any Mortgage Loan. If the Servicer or its designee fails to collect a Prepayment Charge at the time of the related prepayment of any Mortgage Loan subject to such Prepayment Charge, the Servicer shall pay to the Master Servicer at such time (by deposit to the Custodial Account) an amount equal to the amount of the Prepayment Charge not collected; provided, however, that with respect to any Mortgage Loan as to which the original or a copy of the Mortgage Note is not in the Servicer’s possession (after the Servicer has used commercially reasonable efforts to obtain the Mortgage Note from the related Custodian), the Servicer shall not have any obligation to pay the amount of any uncollected Prepayment Charge under this Section 3.20 if the failure to collect such amount is the result of inaccurate or incomplete information regarding Prepayment Charges included on the Mortgage Loan Schedule relating to the related Mortgage Loan. With respect to any Mortgage Loan as to which the original or a copy of the Mortgage Note is not in the Servicer’s possession (after the Servicer has used commercially reasonable efforts to obtain the Mortgage Note from the related Custodian), the Servicer may rely on the Prepayment Charge data set forth on the related Mortgage Loan Schedule and the Servicer shall not have any liability for any loss resulting from the Servicer’s calculation of the Prepayment Charge utilizing the data contained in the related Mortgage Loan Schedule. Notwithstanding the above, the Servicer or its designee may waive (and shall waive, in the case of (ii)(c) below) a Prepayment Charge without paying to the Master Servicer the amount of such Prepayment Charge only if such Prepayment Charge (i) relates to a defaulted Mortgage Loan (defined as 61 days or more delinquent), and such waiver would maximize recovery of total proceeds from the Mortgage Loan, taking into account the amount of such Prepayment Charge and the related Mortgage Loan, or (ii) if the prepayment is not a result of a refinance by the Servicer or any of its affiliates and (a) a default under the Mortgage Loan is reasonably foreseeable and such waiver would maximize recovery of total proceeds taking into account the value of such a prepayment charge and the related Mortgage Loan, (b) the collection of the Prepayment Charge would be in violation of applicable laws or (c) notwithstanding any state or federal law to the contrary, any Prepayment Charge in any instance when a Mortgage Loan is in foreclosure.

Section 3.21

Advance Facility.

(a)

With the prior written consent of the NIMS Insurer, the Servicer is hereby authorized to enter into a financing or other facility (any such arrangement, an “Advance Facility”) under which (1) the Servicer assigns or pledges to another Person (together with such Person’s successors and assigns, an “Advancing Person”) the Servicer’s rights under this Agreement to be reimbursed for any Monthly Advances or Servicing Advances and/or (2) an Advancing Person agrees to fund some or all Monthly Advances and/or Servicing Advances required to be made by the Servicer pursuant to this Agreement. No consent of the Seller, the Master Servicer, the Trustee, the Certificateholders or any other party is required before the Servicer may enter into an Advance Facility. Notwithstanding the existence of any Advance Facility under which an Advancing Person agrees to fund Monthly Advances and/or Servicing Advances on the Servicer’s behalf, the Servicer shall remain obligated pursuant to this Agreement to make Monthly Advances and Servicing Advances pursuant to and as required by this Agreement. If the Servicer enters into an Advance Facility, and for so long as an Advancing Person remains entitled to receive reimbursement for any Monthly Advances and/or Servicing Advances, as applicable, pursuant to this Agreement, then the Servicer shall not be permitted to reimburse itself for Monthly Advances and/or Servicing Advances, but instead the Servicer shall be required to remit amounts collected that would otherwise be retained by the Servicer to reimburse it for previously unreimbursed Monthly Advances (“Monthly Advance Reimbursement Amounts”) and/or previously unreimbursed Servicing Advances (“Servicing Advance Reimbursement Amounts” and together with Monthly Advance Reimbursement Amounts, “Reimbursement Amounts”) (in each case to the extent such type of Reimbursement Amount is included in the Advance Facility) in accordance with the documentation establishing the Advance Facility to such Advancing Person or to a trustee, agent or custodian (an “Advance Facility Trustee”) designated by such Advancing Person. Notwithstanding anything to the contrary herein, in no event shall Monthly Advance Reimbursement Amounts or Servicing Advance Reimbursement Amounts be included in the “Available Distribution Amount” or distributed to Certificateholders.

If the Servicer enters into an Advance Facility, the Servicer and the related Advancing Person shall deliver to the Trustee a written notice of the existence of such Advance Facility (an “Advance Facility Notice”), stating the identity of the Advancing Person and any related Advance Facility Trustee. An Advance Facility Notice may only be terminated by the joint written direction of the Servicer and the related Advancing Person as described in Section 3.21(h) below.

(b)

Reimbursement Amounts shall consist solely of amounts in respect of Monthly Advances and/or Servicing Advances made with respect to the Mortgage Loans for which the Servicer would be permitted to reimburse itself in accordance with this Agreement, assuming the Servicer had made the related Monthly Advance(s) and/or Servicing Advance(s). Notwithstanding the foregoing, no Person shall be entitled to reimbursement from funds held in the Custodial Account for future distribution to Certificateholders pursuant to this Agreement. None of the Master Servicer, the Trustee or the NIMS Insurer shall have any duty or liability with respect to the calculation of any Reimbursement Amount, nor shall the Master Servicer, the Trustee or the NIMS Insurer have any responsibility to track or monitor the administration of the Advance Facility or the payment of Reimbursement Amounts to the related Advancing Person or Advance Facility Trustee. The Servicer shall maintain and provide to any successor Servicer and (upon request) the NIMS Insurer and the Master Servicer a detailed accounting on a loan by loan basis as to amounts advanced by, pledged or assigned to, and reimbursed to any Advancing Person. The successor Servicer shall be entitled to rely on any such information provided by the predecessor Servicer, and the successor Servicer shall not be liable for any errors in such information.

(c)

An Advancing Person who receives an assignment or pledge of the rights to be reimbursed for Monthly Advances and/or Servicing Advances, and/or whose obligations hereunder are limited to the funding of Monthly Advances and/or Servicing Advances shall not be required to meet the criteria for qualification of a subservicer set forth in this Agreement.

(d)

The documentation establishing any Advance Facility shall require that Reimbursement Amounts distributed with respect to each Mortgage Loan be allocated to outstanding unreimbursed Monthly Advances or Servicing Advances (as the case may be) made with respect to that Mortgage Loan on a “first in, first out” (FIFO) basis. Such documentation shall also require the Servicer to provide to the related Advancing Person or Advance Facility Trustee loan by loan information with respect to each Reimbursement Amount distributed to such Advancing Person or Advance Facility Trustee on each Distribution Date, to enable the Advancing Person or Advance Facility Trustee to make the FIFO allocation of each Reimbursement Amount with respect to each Mortgage Loan. The Servicer shall remain entitled to be reimbursed by the Advancing Person or Advance Facility Trustee for all Monthly Advances and Servicing Advances funded by the Servicer to the extent the related rights to be reimbursed therefor have not been assigned or pledged to an Advancing Person.

(e)

The Servicer who enters into an Advance Facility shall indemnify the Seller, the NIMS Insurer, the Master Servicer, the Trustee, the Trust Fund and any successor resulting from any claim by the related Advancing Person, except to the extent that such claim, loss, liability or damage resulted from or arose out of negligence, recklessness or willful misconduct on the part of the Seller, the NIMS Insurer, the Master Servicer, the Trustee or the successor Servicer.

(f)

Any amendment to this Section 3.21 or to any other provision of this Agreement that may be necessary or appropriate to effect the terms of an Advance Facility as described generally in this Section 3.21, including amendments to add provisions relating to a successor Servicer, may be entered into by the Seller, the Trustee, the Master Servicer and the Servicer without the consent of any Certificateholder, but only with the consent of the NIMS Insurer, notwithstanding anything to the contrary in this Agreement or the Trust Agreement.

(g)

Any rights of set-off that the Trust Fund, the Trustee, the Depositor, any successor Servicer or any other Person might otherwise have against any Servicer under this Agreement shall not attach to any rights to be reimbursed for Monthly Advances or Servicing Advances that have been sold, transferred, pledged, conveyed or assigned to any Advancing Person.

(h)

At any time when an Advancing Person shall have ceased funding Monthly Advances and/or Servicing Advances (as the case may be) and the Advancing Person or related Advance Facility Trustee shall have received Reimbursement Amounts sufficient in the aggregate to reimburse all Monthly Advances and/or Servicing Advances (as the case may be) the right to reimbursement for which were assigned to the Advancing Person, then upon the delivery of a written notice signed by the Advancing Person and the related Servicer to the Trustee terminating the Advance Facility Notice (the “Notice of Facility Termination”), the Servicer shall again be entitled to withdraw and retain the related Reimbursement Amounts from the Custodial Account pursuant to the applicable Sections of this Agreement.

(i)

After delivery of any Advance Facility Notice, and until any such Advance Facility Notice has been terminated by a Notice of Facility Termination, this Section 3.21 may not be amended or otherwise modified without the prior written consent of the related Advancing Person.

Section 1.1

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 all Monthly Payments (solely the portion of the Monthly Payment attributable to interest, in the case of Simple Interest Mortgage Loans) (with interest adjusted to the Mortgage Loan Remittance Rate) which were due on the Mortgage 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 and the NIMS Insurer upon request. The Servicer will not be required to make any Advances with respect to reductions in the amount of the monthly payments on Mortgage Loans due to reductions made by a bankruptcy court in the amount of a Scheduled Payment owed by a borrower or a Relief Act Reduction.

The Servicer’s obligation to make such Monthly Advances as to any Mortgage Loan will continue through the last Monthly Payment due prior to the payment in full of the Mortgage 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 Insurance Proceeds and Condemnation Proceeds) with respect to the related Mortgage Loan unless the Servicer deems such Monthly Advance to be a Nonrecoverable Advance, as evidenced by an Officer’s Certificate of the Servicer delivered to the Master Servicer and the NIMS Insurer.

Section 1.2

Due Dates Other Than the First of the Month.

Mortgage Loans having Due Dates other than the first day of a month shall be accounted for as described in this Section 4.04. Any payment due on a day other than the first day of each month shall be considered due on the first day of the month following the month in which that payment is due as if such payment were due on the first day of said month. For example, a payment due on April 15 shall be considered to be due on May 1. Any payment collected on a Mortgage Loan after the Cut-off Date shall be deposited in the Custodial Account. For Mortgage Loans with Due Dates on the first day of a month, deposits to the Custodial Account begin with the payment due on the first of the month following the Cut-off Date.

Section 2.1

Servicing Compensation.

As consideration for servicing the Mortgage Loans subject to this Agreement, the Servicer shall retain the relevant Servicing Fee for each Mortgage Loan remaining subject to this Agreement during any month or part thereof.

The Servicer shall be entitled to recover any unpaid Servicing Fees out of Insurance Proceeds, Condemnation Proceeds, REO Disposition Proceeds or Liquidation Proceeds or from other funds on deposit in the Custodial Account to the extent permitted in Section 3.04 and out of amounts derived from the operations and sale of REO Property to the extent permitted by Section 3.16. Any Prepayment Interest Excess Amount shall be retained by, or paid to, the Servicer as additional compensation.

The foregoing shall not be deemed to limit or restrict the rights and remedies of the Holder of such Residual Certificate, the Trustee and the Trust Fund or the NIMS Insurer 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 Certificateholders (in addition to payment of principal and interest on the Certificates).

Section 3.5

Reporting Requirements of the Commission and Indemnification.

Notwithstanding any other provision of this Agreement, the Servicer acknowledges and agrees that the purpose of Sections 4.02(c) and (d), 5.02, 5.03, 5.04, 6.01(k), 6.03 and 7.04 of this Agreement is to facilitate compliance by the Trustee, the Master Servicer and the Depositor with the provisions of Regulation AB. Therefore, the Servicer agrees that (a) the obligations of the Servicer hereunder shall be interpreted in such a manner as to accomplish that purpose, (b) such obligations may change over time due to interpretive advice or guidance of the Commission, convention or consensus among active participants in the asset-backed securities markets, advice of counsel, or otherwise in respect of the requirements of Regulation AB, (c) the Servicer shall agree to enter into such mutually agreeable amendments to this Agreement as may be necessary, in the reasonable judgment of the Depositor, the Master Servicer and their respective counsel, to comply with such interpretive advice or guidance, convention, consensus, advice of counsel, or otherwise, (d) the Servicer shall otherwise comply with reasonable requests made by the Trustee, the Master Servicer or the Depositor for delivery of additional or different information available to the Servicer as such parties may determine in good faith is necessary to comply with the provisions of Regulation AB and (e) the Servicer shall (i) agree to such modifications and enter into such amendments to this Agreement as may be necessary, in the reasonable judgment of the Depositor, the Master Servicer and their respective counsel, to comply with any such clarification, interpretive guidance, convention or consensus and (ii) promptly upon request provide to the Depositor for inclusion in any periodic report required to be filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), such items of information available to the Servicer regarding this Agreement and matters related to the Servicer, (collectively, the “Servicer Information”), provided that such information shall be required to be provided by the Servicer only to the extent that such shall be reasonably determined by the Depositor and its counsel to be necessary or advisable to comply with the provisions of Regulation AB.

The Servicer hereby agrees to indemnify and hold harmless the Depositor, the Master Servicer, the Trustee, their respective officers and directors and each person, if any, who controls the Depositor, the Trustee or Master Servicer within the meaning of Section 15 of the Securities Act of 1933, as amended (the “Act”), or Section 20 of the Exchange Act, from and against any and all losses, claims, expenses, damages or liabilities to which the Depositor, the Master Servicer, their respective officers or directors and any such controlling person may become subject under the Act or otherwise, as and when such losses, claims, expenses, damages or liabilities are incurred, insofar as such losses, claims, expenses, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Servicer Information or arise out of, or are based upon, the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and will reimburse the Depositor, the Master Servicer, the Trustee, their respective officers and directors and any such controlling person for any legal or other expenses reasonably incurred by it or any of them in connection with investigating or defending any such loss, claim, expense, damage, liability or action, as and when incurred; provided, however, that the Servicer shall be liable only insofar as such untrue statement or alleged untrue statement or omission or alleged omission relates solely to the information in the Servicer Information furnished to the Depositor, the Trustee or Master Servicer by or on behalf of the Servicer specifically in connection with this Agreement.

Section 3.6

Purchase of Distressed Mortgage Loans.

The NIMS Insurer may, at its option, purchase a Distressed Mortgage Loan; provided, however, prior to any such purchase, the Servicer shall be required to continue to make Monthly Advances with respect to such Distressed Mortgage Loans pursuant to Section 4.03 unless it has deemed such Monthly Advances to be a Nonrecoverable Advance. Any such purchase shall be accomplished by remittance to the Master Servicer of the Purchase Price for the Distressed Mortgage Loan for deposit into the Collection Account established by the Master Servicer pursuant to the Trust Agreement. The Trustee and the Servicer shall immediately effectuate the conveyance of the purchased Distressed Mortgage Loan to the NIMS Insurer exercising the purchase option, including prompt delivery of the Servicing File and all related documentation to the applicable NIMS Insurer.

ARTICLE IV

THE SERVICER

Section 4.1

Merger or Consolidation of the Servicer.

Subject to the following paragraph, the Servicer shall keep in full effect its existence, rights and franchises as a Delaware limited liability company, and shall obtain and preserve its qualification to do business in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement or any of the Mortgage Loans and to perform its duties under 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 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 ▇▇▇▇▇▇ ▇▇▇- and ▇▇▇▇▇▇▇ Mac-approved servicer in good standing.

Section 4.2

Limitation on Liability of the Servicer and Others.

Neither the Servicer nor any of the directors, officers, employees or agents of the Servicer shall be under any liability to the Master Servicer, the NIMS Insurer, the Depositor or the Trustee 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 accordance 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 Mortgage 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 undertake any such action which it may deem 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 Trust Fund for the reasonable legal expenses and costs of such action.

Section 4.3

Limitation on Resignation and Assignment by the Servicer.

This Agreement has been entered into with the Servicer in reliance upon the independent status of the Servicer, and the representations as to the adequacy of its servicing facilities, plant, personnel, records and procedures, its integrity, reputation and financial standing, and the continuance thereof. Therefore, except as expressly provided in this Section 7.03 and Sections 3.21, 7.01 and 7.04, the Servicer shall neither assign its rights under this Agreement or the servicing hereunder nor delegate its duties hereunder or any portion thereof, or sell or otherwise dispose of all or substantially all of its property or assets without, in each case, the prior written consent of the Seller, the Master Servicer and the NIMS Insurer which consent, in the case of an assignment of rights or delegation of duties, shall be granted or withheld in the discretion of the Seller, the Master Servicer and the NIMS Insurer and which consent, in the case of a sale or disposition of all or substantially all of the property or assets of the Servicer, shall not be unreasonably withheld by any of them; provided that in each case, there must be delivered to the Seller, the Master Servicer, the Trustee and the NIMS Insurer a letter from each Rating Agency to the effect that such transfer of servicing or sale or disposition of assets will not result in a qualification, withdrawal or downgrade of the then-current rating of any of the Certificates or the NIM Securities to be issued in the NIMS Transaction. Notwithstanding the foregoing, the Servicer, without the consent of the Seller, the Master Servicer, the Trustee or the NIMS Insurer, may retain third party contractors to perform certain servicing and loan administration functions, including without limitation, hazard insurance administration, tax payment and administration, flood certification and administration, collection services and similar functions; provided that the retention of such contractors by Servicer shall not limit the obligation of the Servicer to service the Mortgage Loans pursuant to the terms and conditions of this Agreement.

Notwithstanding the preceding paragraph of this Section 7.03 or any other provisions of this Agreement to the contrary, the Servicer shall have the right, subject to the succeeding sentence, to pledge and assign all of the Servicer’s right, title and interest in, to and under this Agreement to the Servicing Rights Pledgee in order to finance the Servicer’s servicing rights hereunder, provided that such assignment shall not impair any existing rights or claims that the Seller, the Master Servicer, the NIMS Insurer, the Depositor or the Trustee may have against the Servicer and (ii) the Seller, the Master Servicer, the NIMS Insurer, the Depositor and the Trustee shall have no obligation or liability to the Servicing Rights Pledgee under any such financing arrangements. If, as a result of a default by the Servicer under any such financing arrangement, the Servicing Rights Pledgee acquires such servicing rights and appoints a successor Servicer under this Agreement (including itself as successor Servicer), any such successor Servicer must meet all requirements for successor Servicers pursuant to Section 9.01. If, pursuant to any provision hereof, the duties of the Servicer are transferred to a successor Servicer, the entire amount of the Servicing Fee and other compensation payable to the Servicer pursuant hereto shall thereafter be payable to such Servicer.

The Servicer shall not resign from the obligations and duties hereby imposed on it except by mutual consent of the Servicer, the Master Servicer and the NIMS 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, the Trustee and the NIMS Insurer which Opinion of Counsel shall be in form and substance reasonably acceptable to each of them. No such resignation shall become effective until a successor shall have assumed the Servicer’s responsibilities and obligations hereunder in the manner provided in Section 9.01.

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, except to the extent permitted by and in accordance with this Section 7.03 and Sections 3.21, 7.01 and 7.04, without the prior written consent of the Seller, the Master Servicer and the NIMS Insurer, 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.

Section 4.4

Subservicing Agreements and Successor Subservicer.

(a)

The Servicer shall not hire or otherwise utilize the services of any Subservicer to fulfill any of the obligations of the Servicer as servicer under this Agreement unless the Servicer complies with the provisions of paragraph (b) of this Section 7.04 and the proposed Subservicer (i) is an institution which is an approved ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac Seller/Servicer as indicated in writing, (ii) represents and warrants that it is in compliance with the laws of each state as necessary to enable it to perform its obligations under such subservicing agreement and (iii) is acceptable to the NIMS Insurer. The Servicer shall not hire or otherwise utilize the services of any Subcontractor, and shall not permit any Subservicer to hire or otherwise utilize the services of any Subcontractor, to fulfill any of the obligations of the Servicer as servicer under this Agreement unless the Servicer complies with the provisions of paragraph (c) of this Section 7.04.

(b)

The Servicer shall give prior written notice to the Trustee, the Master Servicer, the Depositor and the NIMS Insurer of the appointment of any Subservicer and shall furnish to the Trustee, Master Servicer, the Depositor and the NIMS Insurer a copy of any related subservicing agreement. For purposes of this Agreement, the Servicer shall be deemed to have received payments on Mortgage Loans immediately upon receipt by any Subservicer of such payments. Any such subservicing agreement shall be acceptable to the NIMS Insurer and be consistent with and not violate the provisions of this Agreement. Each subservicing agreement shall provide that a successor Servicer shall have the option to terminate such agreement without payment of any fees if the predecessor Servicer is terminated or resigns. The Servicer shall cause any Subservicer used by the Servicer (or by any Subservicer) to comply with the provisions of this Section 7.04 and with Sections 4.02(c), 5.02, 5.03(a), 5.03(b), 5.04, 6.01(k) and 6.03 and Exhibit H of this Agreement to the same extent as if such Subservicer were the Servicer. The Servicer shall be responsible for obtaining from each Subservicer and delivering to the Trustee, the NIMS Insurer, the Master Servicer and the Depositor any servicer compliance statement required to be delivered by such Subservicer under Section 5.03(a), any reports on assessment of compliance and attestation required to be delivered by such Subservicer under Sections 5.02 and 5.04 and any certification required to be delivered under 5.03(b) to the Person that will be responsible for signing the Sarbanes Certification under Section 5.04 as and when required to be delivered hereunder.

(c)

The Servicer shall give written notice to the Master Servicer, the Trustee and the Depositor of the appointment of any Subcontractor and a written description (in form and substance satisfactory to the Master Servicer and the Depositor) of the role and function of each Subcontractor determined to be a Participating Entity utilized by the Servicer or any Subservicer, specifying (A) which (if any) of such Subcontractors are Participating Entities, and (B) which elements of the servicing criteria set forth under Item 1122(d) of Regulation AB will be addressed in assessments of compliance provided by each Subcontractor identified pursuant to clause (A) of this paragraph.

As a condition to the utilization of any Subcontractor determined to be a Participating Entity, the Servicer shall cause any such Subcontractor used by the Servicer (or by any Subservicer) for the benefit of the Trustee, the NIMS Insurer, the Master Servicer and the Depositor to comply with the provisions of Sections 4.02(c), 5.02, 5.04, 6.01(k) and 6.03 and Exhibit H of this Agreement to the same extent as if such Subcontractor were the Servicer. The Servicer shall be responsible for obtaining from each Subcontractor and delivering to the Trustee, the NIMS Insurer, the Master Servicer and the Depositor any assessment of compliance and attestation required to be delivered by such Subcontractor under Sections 5.02 and 5.04, in each case as and when required to be delivered.

The Servicer acknowledges that a Subservicer or Subcontractor that performs services with respect to mortgage loans involved in this transaction in addition to the Mortgage Loans may be determined by the Depositor to be a Participating Entity on the basis of the aggregate balance of such mortgage loans, without regard to whether such Subservicer or Subcontractor would be a Participating Entity with respect to the Mortgage Loans viewed in isolation. In connection with complying with the requirements set forth in the previous sentence, the Servicer shall (A) respond as promptly as practicable to any good faith request by the Trustee, the Master Servicer or the Depositor for information regarding each Subservicer and each Subcontractor and (B) cause each Subservicer and each Subcontractor with respect to which the Trustee, the Master Servicer or the Depositor requests delivery of an assessment of compliance and accountants’ attestation to deliver such within the time required under Section 5.04.

(d) Notwithstanding any subservicing agreement or the provisions of this Agreement relating to agreements or arrangements between the Servicer and a Subservicer, Subcontractor or other third party or reference to actions taken through a Subservicer, a Subcontractor, another third party or otherwise, the Servicer shall remain obligated and primarily liable to the Trust Fund, the Trustee, the Master Servicer, the NIMS Insurer and the Certificateholders for the servicing and administering of the Mortgage Loans in accordance with the provisions hereof without diminution of such obligation or liability by virtue of any subservicing, subcontracting or other agreements or arrangements or by virtue of indemnification from a Subservicer, Subcontractor or a third party and to the same extent and under the same terms and conditions as if the Servicer alone were servicing the Mortgage Loans, including with respect to compliance with Item 1122 of Regulation AB. The Servicer shall be entitled to enter into any agreement with a Subservicer, Subcontractor or a third party for indemnification of the Servicer by such Subservicer, Subcontractor or third party and nothing contained in the Agreement shall be deemed to limit or modify such indemnification.

Section 4.5

Inspection.

The Servicer shall provide the Master Servicer and the NIMS Insurer, 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. In addition, upon request of the Master Servicer, the Servicer shall promptly provide complete and correct data fields regarding the Mortgage Loans; provided that in all instances the Servicer shall provide such information no later than five (5) Business Days after such request. Upon request, the Servicer shall furnish to the Master Servicer and the NIMS Insurer its most recent publicly available financial statements and such other information relating to its capacity to perform its obligations under this Agreement.

ARTICLE V

TERMINATION

Section 5.1

Termination for Cause.

(a)

Any of the following occurrences shall constitute an event of default (each, an “Event of Default”) on the part of the Servicer:

(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 two (2) Business Days after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Master Servicer or the NIMS Insurer; or

(ii)

any failure by the Servicer to duly perform, within the required time period and without notice, its obligations to provide any certifications required pursuant to Sections 5.02, 5.03 or 5.04 (including with respect to such certifications required to be provided by any Subservicer or Subcontractor pursuant to Section 7.04); or

(iii)

except with respect to those items listed in clause (ii) above, any failure by the Servicer to duly perform, within the required time period, without notice or grace period, its obligations to provide any other information, data or materials required to be provided hereunder pursuant to Sections 4.02(c), 4.02(d), 6.01(k) and 7.04, including any items required to be included in any Exchange Act report; or

(iv)

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, marshalling 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, marshalling 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 ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac lender/servicer; or

(viii)

the Servicer attempts to assign the servicing of the Mortgage Loans or its right to servicing compensation hereunder or the Servicer attempts to sell or otherwise dispose of all or substantially all of its property or assets or to assign this Agreement or the servicing responsibilities hereunder or to delegate its duties hereunder in a manner not permitted under this Agreement; or

(ix)

(a) any reduction or withdrawal of the ratings of the Servicer as a servicer of subprime mortgage loans by one or more of the Rating Agencies that maintains a servicer rating system to “below average” or (b) any reduction, withdrawal or qualification of the servicing ratings of the Servicer by any Rating Agency which results in (1) the inability of the Servicer to act as a primary or special servicer for any mortgage-backed or asset-backed transaction rated or to be rated by any Rating Agency without any backup servicing arrangements or (2) a downgrade of any of the Offered Certificates by any Rating Agency.

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, the Trustee or the NIMS Insurer may have at law or equity to damages, including injunctive relief and specific performance, the Master Servicer or the NIMS Insurer, by notice in writing to the Servicer, may 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 Mortgage Loans or otherwise, shall pass to and be vested in a successor servicer appointed by the Master Servicer with the consent of the NIMS Insurer. Upon written request from the Master Servicer, the Servicer shall prepare, execute and deliver to the successor entity designated by the Master Servicer 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 Mortgage Loans and related documents, at the Servicer’s sole expense. The Servicer shall cooperate with the Seller, the Master Servicer, the NIMS Insurer, the Trustee 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 Mortgage Loans.

Notwithstanding the first through third paragraphs of this Section 8.01(a) or the first and second paragraphs of Section 8.03, upon a termination and removal of the Servicer pursuant to Section 8.01 or Section 8.03, the Master Servicer, in coordination with the Seller, agrees to use commercially reasonable efforts to sell the servicing rights with respect to the Mortgage Loans to a third party servicer of subprime mortgage loans that is acceptable to the Master Servicer and the Seller, in their reasonable discretion, provided that (i) such transfer of servicing rights to such successor Servicer otherwise meets the requirements of Section 9.01 hereof and (ii) the Master Servicer employs commercially reasonable efforts to maximize the net proceeds of such sale. Upon such sale and transfer and compliance by the Servicer with all of its obligations under this Agreement, the Master Servicer shall remit to the Servicer the net sale proceeds actually received with respect to any such sale, net of any costs and expenses that are incurred by the Master Servicer, the Seller, the Trustee or the Trust Fund in connection with such sale, the termination of the Servicer under this Section 8.01 or Section 8.03 hereof, and the transfer of servicing contemplated hereby, and any other amounts that may be due and owing from the Servicer to the Seller, the Master Servicer, the Trustee or the Trust Fund pursuant to this Agreement; provided, however, that overhead, labor and other indirect costs of the successor servicer incurred in connection with such transfer of servicing shall not be offset against the net sale proceeds of such sale. Notwithstanding any provision of this Agreement to the contrary, the Master Servicer shall remit to the Servicer the Net Sale Proceeds referred to above no later than 14 days following the receipt of such proceeds from the purchaser of the servicing rights. All reasonable and customary costs and expenses incurred by the Master Servicer, the Seller, the Trustee or the Trust Fund in connection with the transfer of servicing contemplated hereby shall, if not netted from the proceeds of the sale of the servicing rights in accordance with the preceding sentence, be paid by the Servicer.

(b)

By a written notice to the Servicer, the Master Servicer with the consent of the NIMS 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.

(c)

(1) In the event of an Event of Default, notwithstanding anything to the contrary above, the Master Servicer hereby agrees that upon delivery to the Master Servicer by the Servicing Rights Pledgee of a letter signed by the Servicer within thirty (30) days of when notification of such event shall have been provided to the Servicer, whereunder the Servicer shall resign as Servicer under this Agreement, the Master Servicer shall appoint the Servicing Rights Pledgee or its designee as successor servicer, provided that at the time of such appointment, the Servicing Rights Pledgee or such designee meets the requirements of a successor servicer set forth in Sections 7.01 and 9.01 and the Servicing Rights Pledgee or such designee agrees to be subject to the terms of this Agreement. This 30-day period shall terminate immediately (i) at the close of business on the second Business Day of such 30-day period if (A) the Servicer was terminated because of an Event of Default described in Section 8.01(a)(i) for failing to make a required Monthly Advance, and (B) the Servicer shall have failed to make (or cause to be made) such Monthly Advance, or shall fail to reimburse (or cause to be reimbursed) the Master Servicer for a Monthly Advance made by the Master Servicer, by the close of business on such second Business Day, or (ii) at the close of business on the second business Day following the date (if any) during such 30-day period on which a Monthly Advance is due to be made, if the Servicer shall have failed to make (or caused to be made) such Monthly Advance, or the Servicer shall have failed to reimburse (or cause to be reimbursed) the Master Servicer for such Monthly Advance, by the close of business on such second Business Day; provided that such 30-day period shall only be terminated to the extent that the Servicing Rights Pledgee has received notice of such failure from the Master Servicer and the Servicing Rights Pledgee has not cured or caused the cure of such failure within two (2) Business Days following receipt of notice, provided, however, that such notice requirement shall only be applicable to the extent that the Master Servicer has been provided with the written address and contact information for the Servicing Rights Pledgee.

(2)

In the event that the Servicing Rights Pledgee does not deliver to the Master Servicer the letter described in preceding paragraph within the time period specified therein, the Master Servicer shall be the successor in all respects to the Servicer in its capacity as Servicer under this Agreement and the transactions set forth or provided for herein, and all the responsibilities, duties and liabilities relating thereto and arising thereafter shall be assumed by the Master Servicer.

Section 5.2

Termination Without Cause.

This Agreement shall terminate upon: (i) the later of (a) the distribution of the final payment or liquidation proceeds on the last Mortgage Loan to the Master Servicer (or advances by the Servicer for the same), and (b) the disposition of all REO Property acquired upon foreclosure of the last Mortgage Loan and the remittance of all funds due hereunder, or (ii) mutual consent of the Servicer, the Seller and the Master Servicer in writing, provided such termination is also acceptable to the Rating Agencies and the NIMS Insurer or (iii) with respect to some or all of the Mortgage Loans, at the sole option of the Seller, without cause, upon 30 days written notice, subject to the limitations set forth below. Any such notice of termination shall be in writing and delivered to the Trustee, the Master Servicer, the NIMS Insurer and the Servicer by registered mail to the address set forth in Section 9.04 of this Agreement. The Servicer shall comply with the termination procedures set forth in Sections 8.01, 8.02 and 9.01 hereof. The Master Servicer or the Trustee shall have no right to terminate the Servicer pursuant to Section 8.02.

In the event the Seller terminates the Servicer without cause with respect to some or all of the Mortgage Loans in accordance with Section 8.02(iii), (x) the Seller shall be required to pay to the Servicer a Termination Fee in an amount equal to the product of the Termination Fee Rate and the outstanding principal balance of the terminated Mortgage Loans as of the date of such termination; provided that no Termination Fee shall be paid or payable with respect to the unpaid principal balance of any terminated Distressed Mortgage Loan and (y) the Master Servicer or a successor servicer shall reimburse the Servicer for all accrued and unpaid Servicing Fees and unreimbursed Monthly Advances and Servicing Advances upon the transfer of servicing to such successor servicer.

Section 5.3

Special Termination Events.

If, as of any date of determination, any of the following circumstances shall exist with respect to the Mortgage Loans (each, a “Trigger Event”), subject to the prior written consent of the NIMS Insurer, the Master Servicer and the Seller shall have the right, by notice in writing to the Servicer, to terminate all of the rights and obligations of the Servicer under this Agreement:

(i)

the “60 Day Delinquency Average” of the Mortgage Loans exceeds twelve percent (12%) of the unpaid principal balance of the Mortgage Loans. As used herein, the “60 Day Delinquency Average” is equal to the average percentage, as of the end of the Due Periods relating to the three immediately preceding Remittance Dates, of the scheduled principal balance of all Mortgage Loans that are (i) 60 or more days delinquent (but not in bankruptcy or foreclosure and which have not become REO Properties), (ii) in bankruptcy and 60 or more days delinquent, (iii) in foreclosure and 60 or more days delinquent or (iv) REO Properties; or

(ii)

as of any date, the “Realized Losses” for the Mortgage Loans for the then most recent twelve month period exceeds 1.50% of the unpaid principal balance of such Mortgage Loans as of the beginning of such twelve (12) month period. As used herein, with respect to any liquidated Mortgage Loan, the related “Realized Loss” is amount equal to (i) the unpaid principal balance of the related liquidated Mortgage Loan as of the date of liquidation, minus (ii) Liquidation Proceeds received, to the extent allocable to principal, net of amounts that are reimbursable therefrom to the Servicer with respect to such Mortgage Loan including expenses of liquidation; or

(iii)

the cumulative Realized Losses for the Mortgage Loans, calculated as a percentage of the Cut-off Date principal balance of the Mortgage Loans exceeds the percentage set forth in the first column below at any time during the corresponding period from the Closing Date set forth in the second column below:

Trigger Percentage	Applicable Period from Closing Date

4.25%	At any time after the end of the 48^th complete calendar month following the Closing Date

Upon receipt by the Servicer of a written termination notice pursuant to this Section 8.03, all authority and power of the Servicer under this Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in a successor servicer appointed by the Master Servicer, with the consent of the Seller and the NIMS Insurer. Upon written request from the Master Servicer, 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 or assignment of the Mortgage Loans and related documents, at the Servicer’s sole expense. The Servicer shall cooperate with the Master Servicer, the Seller, the NIMS Insurer, the Trustee 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 Mortgage Loans.

By a written notice the Master Servicer, with the consent of the Seller and the NIMS Insurer may waive any Trigger Event hereunder and its consequences. Upon any waiver of a Trigger Event in any period, such event shall cease to exist for such period. No such waiver shall extend to any subsequent or other default or Trigger Event or impair any right consequent thereon except to the extent expressly so waived.

No Termination Fee shall be payable to the Servicer upon a termination pursuant to this Section 8.03.

In the event that a Seller intends to transfer the servicing of Mortgage Loans which have become Distressed Mortgage Loans to a Special Servicer for servicing pursuant to Section 8.04, then the Servicer and the Seller agree to renegotiate the Trigger Events in a manner reasonably acceptable to both parties prior to effecting any such transfer. Renegotiation of the Trigger Events will not require the consent of Certificateholders or any other party so long as the Seller have obtained written confirmation from the applicable Rating Agencies rating the Certificates that such renegotiated Trigger Events will not cause a qualification, reduction or withdrawal of the current ratings assigned to the Certificates by such Rating Agencies.

Section 5.4

Termination for Distressed and Released Mortgage Loans.

(a)

This Agreement shall be terminated with respect to the servicing of those Mortgage Loans that are determined to be Released Mortgage Loans as of the Transfer Date and servicing of such Mortgage Loans shall be transferred to the Released Mortgage Transferee or its designee.

(b)

All reasonable costs and expenses incurred in connection with the delivery of the Servicing Files and the other necessary data to the Released Mortgage Transferee or its designee shall be paid by the Released Mortgage Transferee from its own funds without reimbursement therefor within fifteen (15) Business Days upon receipt of an invoice from the Servicer. The Released Mortgage Transferee shall be responsible for the delivery of all required transfer notices pursuant to the Trust Agreement and will send a copy of the transfer notices to the Master Servicer and the Trustee.

(c)

Notwithstanding the foregoing provisions of this Section 8.04, the NIMS Insurer may, at its option, elect to purchase a Distressed Mortgage Loan at a price equal to its Purchase Price. Prior to such purchase, the Servicer shall be required to continue to make Monthly Advances with respect to such Distressed Mortgage Loan pursuant to Section 4.03. Any such purchase of a Distressed Mortgage Loan shall be accomplished by remittance to the Master Servicer for deposit in the Collection Account established pursuant to Section 4.01 of the Trust Agreement of the amount of the Purchase Price. The Servicer on behalf of the Master Servicer shall take reasonable steps to effectuate the transfer of servicing of such Distressed Mortgage Loan to the NIMS Insurer to the extent necessary, including the prompt delivery of all Servicing Files and other related documentation to the NIMS Insurer or its designee.

ARTICLE VI

MISCELLANEOUS PROVISIONS

Section 6.1

Successor to the Servicer.

Simultaneously with the termination of the Servicer’s responsibilities and duties under this Agreement (a) pursuant to Sections 6.02, 7.03, 8.01 or 8.02(ii), the Master Servicer shall (i) within 90 days of the Servicer’s notice of such termination, succeed to and assume all of the Servicer’s responsibilities, rights, duties and obligations under this Agreement, or (ii) appoint a successor 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) pursuant to a termination under Section 8.02(iii) or Section 8.03, the Seller shall appoint a successor 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. Any successor to the Servicer shall be subject to the approval of the Master Servicer and the NIMS Insurer. Any approval of a successor servicer by the Master Servicer and the NIMS Insurer, shall, if the successor servicer is not at that time a servicer of other Mortgage Loans for the Trust Fund, be conditioned upon the receipt by the Master Servicer, the NIMS Insurer, the Seller and the Trustee of a letter from each Rating Agency 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 or the NIM Securities to be issued in the NIMS Transaction. 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 Mortgage Loans as it and such successor shall agree, provided, however, that no such compensation shall be in excess of that permitted the Servicer 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 shall be appointed pursuant to this Section 9.01 and shall in no event relieve the Servicer of the representations and warranties made pursuant to Sections 6.01 and the remedies available to the Master Servicer, the Trustee, the NIMS Insurer and the Seller under Sections 6.02, 6.03 and 6.04, it being understood and agreed that the provisions of such Sections 6.01, 6.02, 6.03 and 6.04 shall be applicable to the Servicer notwithstanding any such resignation or termination of the Servicer, or the termination of this Agreement. Neither the Master Servicer, in its capacity as successor servicer, nor any other successor servicer shall be responsible for the lack of information and/or documents that it cannot otherwise obtain through reasonable efforts.

Within a reasonable period of time, but in no event longer than 30 days of 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 of any Mortgage Notes and the related documents in the Servicer’s possession. The Servicer shall cooperate with the Trustee, 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 Mortgage Loans.

Any successor appointed as provided herein shall execute, acknowledge and deliver to the Trustee, the Servicer, the Master Servicer, the NIMS 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 and provide for the same remedies set forth in Sections 6.02, 6.03 and 6.04 herein and (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 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, 8.02 or 8.03 shall not affect any claims that the Seller, the Master Servicer, the NIMS 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 8.02(iii) 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 Mortgage 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, it shall notify the Seller and Master Servicer, the NIMS Insurer and the Depositor of such appointment in accordance with the procedures set forth in Section 9.04.

Notwithstanding any provision herein to the contrary, upon the termination or resignation of the Servicer under this Agreement pursuant to Sections 6.02, 7.03, 8.01, 8.02 (other than in accordance with Section 8.02(iii)) or 8.03, the party appointing a successor servicer hereunder (whether a Seller or the Master Servicer) shall use commercially reasonable efforts (without loss, cost or expense to such party) to cause the servicer selected as the successor servicer of the Mortgage Loans to reimburse the Servicer for all outstanding unreimbursed Monthly Advances and Servicing Advances (including but not limited to trailing expenses representing Servicing Advances incurred prior to but invoiced after the date of termination) and all accrued and unpaid Servicing Fees upon the transfer of servicing to such successor servicer; provided, however, that if such successor is unwilling to do so, then the party appointing such successor servicer will require the successor servicer to reimburse the Servicer as such amounts are received from the related Mortgage Loans, with the order of reimbursement being in direct order of the oldest outstanding Servicing Fee, Monthly Advance or Servicing Advance, as the case may be. In addition to the foregoing, following the termination or resignation of the Servicer under this Agreement, the Servicer shall continue to be entitled to the benefits of Section 6.03 with respect to events occurring prior to such termination.

Section 6.2

Costs.

The Seller shall pay the legal fees and expenses of its attorneys. Costs and expenses incurred in connection with the transfer of the servicing responsibilities, including fees for delivering Servicing Files, shall be paid by (i) the terminated or resigning servicer if such termination or resignation is a result of an occurrence of a termination event under Section 8.01 or a Trigger Event under Section 8.03, (ii) the related Seller if such termination is pursuant to Section 8.02(iii) and (iii) in all other cases by the Trust Fund. Subject to Section 2.02, the Seller, on behalf of the Depositor, shall pay the costs associated with the preparation, delivery and recording of Assignments of Mortgages by the Servicer.

Section 6.3

Protection of Confidential Information.

The Servicer shall keep confidential and shall not divulge to any party, without the Seller’s prior written consent, any nonpublic information pertaining to the Mortgage Loans or any borrower thereunder, except (i) to the extent that it is appropriate for the Servicer to do so in working with legal counsel, auditors, taxing authorities or other governmental agencies or it is otherwise in accordance with Accepted Servicing Practices or (ii) upon request from the Master Servicer pursuant to Section 7.05.

Section 6.4

Section 1.1

Severability Clause.

Any part, provision, representation or warranty of this Agreement which is prohibited or which is held to be void or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof. 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 Mortgage 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 1.2

No Personal Solicitation.

From and after the Closing Date, the Servicer hereby agrees that it will not take any action or permit or cause any action to be taken by any of its agents or affiliates, or by any independent contractors on the Servicer’s behalf, to personally, by telephone or mail, solicit the borrower or obligor under any related Mortgage Loan to refinance a Mortgage Loan, in whole or in part, without the prior written consent of the Seller. It is understood and agreed that all rights and benefits relating to the solicitation of any Mortgagors and the attendant rights, title and interest in and to the list of such Mortgagors and data relating to their Mortgages (including insurance renewal dates) shall be transferred to the Trustee pursuant hereto on the Closing Date and the Servicer shall take no action to undermine these rights and benefits. Notwithstanding the foregoing, it is understood and agreed that (i) promotions undertaken by the Servicer or any affiliate thereof which are directed to the general public at large, including, without limitation, mass mailings based on commercially acquired mailing lists, newspaper, radio and television advertisements and (ii) offers to refinance a Mortgage Loan following the Servicer’s receipt of a request for verification of mortgage or payoff demand related to a Mortgagor (other than those initiated in response to a solicitation initiated by the Servicer or any of its agents or affiliates) shall not constitute solicitation under this Section 9.06.

Section 1.3

Counterparts.

This Agreement may be executed simultaneously in any number of counterparts. Each counterpart shall be deemed to be an original, and all such counterparts shall constitute one and the same instrument.

Section 1.4

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 1.5

Further Agreements.

The Seller and the Servicer each agree to execute and deliver to the other such reasonable and appropriate additional documents, instruments or agreements as may be necessary or appropriate to effectuate the purposes of this Agreement.

Section 1.6

Intention of the Parties.

It is the intention of the parties that the Seller is conveying, and the Servicer is receiving only a contract for servicing the Mortgage Loans. Accordingly, the parties hereby acknowledge that the Trust Fund remains the sole and absolute owner of the Mortgage Loans (other than the servicing rights) and all rights related thereto.

Section 1.7

Successors and Assigns; Assignment of Servicing Agreement.

This Agreement shall bind and inure to the benefit of and be enforceable by the Servicer, the Seller, the NIMS Insurer and the Master Servicer and their respective successors and assigns.

Section 1.9

Amendment.

This Agreement may be amended from time to time by the Servicer and the Seller, with (i) the prior written consent of the NIMS Insurer and (ii) the written agreement signed by the Master Servicer, the Seller and the Servicer; provided that the party requesting such amendment shall, at its own expense, provide the Trustee, the NIMS Insurer, the Master Servicer and the Seller with an Opinion of Counsel that such amendment will not materially adversely affect the interest of the Certificateholders in the Mortgage Loans or the NIM Securities to be issued in the NIMS Transaction. Any such amendment shall be deemed not to adversely affect in any material respect any interest of the Certificateholders in the Mortgage Loans or the NIM Securities to be issued in the NIMS Transaction, if the Trustee receives written confirmation from each Rating Agency that such amendment will not cause such Rating Agency to reduce, qualify or withdraw the then current rating assigned to the Certificates and the NIM Securities (and any Opinion of Counsel received by the Trustee, the NIMS Insurer, the Master Servicer and the Seller in connection with any such amendment may rely expressly on such confirmation as the basis therefor) provided, however, this Agreement may be amended by the Servicer, the Seller, the Master Servicer and the Trustee from time to time without the delivery of an Opinion of Counsel described above to the extent necessary, in the judgment of the Seller and its counsel, to comply with any Commission requirements.

Section 1.10

Waivers.

Section 1.13

Intended Third Party Beneficiaries.

Notwithstanding any provision herein to the contrary, the parties to this Agreement agree that it is appropriate, in furtherance of the intent of such parties as set forth herein, that the Trustee and the NIMS Insurer receive the benefit of the provisions of this Agreement as intended third party beneficiaries of this Agreement to the extent of such provisions. The Servicer shall have the same obligations to the Trustee and the NIMS Insurer as if they were parties to this Agreement, and the Trustee and the NIMS Insurer shall have the same rights and remedies to enforce the provisions of this Agreement as if they were parties to this Agreement. The Servicer shall only take direction from the Master Servicer (if direction by the Master Servicer is required under this Agreement) unless otherwise directed by this Agreement or the Credit Risk Manager Agreement. Notwithstanding the foregoing, all rights of the Trustee hereunder and all rights and obligations of the Master Servicer hereunder (other than the right to indemnification) shall terminate upon the termination of the Trust Fund pursuant to the Trust Agreement and all rights of the NIMS Insurer set forth in this Agreement (other than the right of indemnification) shall exist only so long as the NIM Securities issued pursuant to the NIMS Transaction remain outstanding or the NIMS Insurer is owed amounts in respect of its guarantee of payment on such NIM Securities.
