POOLING AND SERVICING AGREEMENT, dated as of December 1, 2005, among NOMURA ASSET ACCEPTANCE CORPORATION, a Delaware corporation, as depositor (the “Depositor”), NOMURA CREDIT & CAPITAL, INC., a Delaware corporation, as seller (in such capacity, the “Seller”), GMAC MORTGAGE CORPORATION, a Pennsylvania corporation, as servicer (the “Servicer”), HSBC BANK USA, NATIONAL ASSOCIATION, a national banking association, not in its individual capacity, but solely as trustee (the “Trustee”) and ▇▇▇▇▇ FARGO BANK, N.A., a national banking association, as master servicer (the “Master Servicer”), as securities administrator (the “Securities Administrator”) and as a custodian (a “Custodian”).

PRELIMINARY STATEMENT

The Depositor is the owner of the Trust Fund that is hereby conveyed to the Trustee in return for the Certificates.

As provided herein, the Trustee, shall elect that the Trust Fund (exclusive of the assets held in the Basis Risk Reserve Fund and the Interest Rate Cap Account) be treated for federal income tax purposes as comprising four real estate mortgage investment conduits (each a “REMIC” or, in the alternative, the “Subsidiary REMIC,” “Intermediate REMIC 1,” “Intermediate REMIC 2” and the “Master REMIC”). For purposes of the REMIC Provisions, each Certificate other than the Class X-2 Certificate and Class R Certificate represents ownership of a regular interest in the Master REMIC. In addition, the LIBOR and Fixed Rate Certificates (other than the Class A-IO Certificates) represent the right to receive payments pursuant to contractual arrangements as described in Section 5.10(e) of this Agreement. The Class R Certificate represents ownership of the sole class of residual interest in each of the Subsidiary REMIC, Intermediate REMIC 1, Intermediate REMIC 2 and the Master REMIC for purposes of the REMIC Provisions.

The Master REMIC shall hold as its assets the several classes of uncertificated Lower Tier Interests in Intermediate REMIC 2, other than the Class LT3-R Interest, and each such Lower Tier Interest is hereby designated as a regular interest in Intermediate REMIC 2 for purposes of the REMIC Provisions. Intermediate REMIC 2 shall hold as its assets the several classes of uncertificated Lower Tier Interests in Intermediate REMIC 1, other than the Class LT2-R Interest, and each such Lower Tier Interest is hereby designated as a regular interest in Intermediate REMIC 1. Intermediate REMIC 1 shall hold as its assets the several classes of uncertificated Lower Tier Interests in the Subsidiary REMIC, other than the Class LT1-R Interest, and each such Lower Tier Interest is hereby designated as a regular interest in the Subsidiary REMIC. The Subsidiary REMIC shall hold as its assets the property of the Trust Fund other than (i) the Lower Tier Interests in the Subsidiary REMIC and any Intermediate REMIC, (ii) the Interest Rate Cap Account and (iii) the Basis Risk Reserve Fund. 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 36th month following the month of the scheduled maturity of the Mortgage Loan held in the Trust Fund as of the Closing Date having the latest maturity date.

___________________________

(1)

The interest rate for the Class LT1-Pool-PO Interest for each Distribution Date before the Distribution Date in July 2008 (and the related Accrual Period), is a per annum rate of 0%; and for each Distribution Date thereafter is a per annum rate equal to the Net WAC Rate for the related Due Period.

(2)

This interest will have an initial principal balance equal to (i) the aggregate of the Stated Principal Balances of the Mortgage Loans as of the Cut-off Date minus (ii) the sum of the initial principal balances of the remaining Lower Tier Interests in the Subsidiary REMIC.

(3)

For each Distribution Date on and after the Distribution Date in July 2008 (and the related Accrual Period), this Lower Tier Interest shall bear interest at a per annum rate equal to the Net WAC Rate for the related Due Period.

(4)

This interest will have an initial principal balance equal to the excess of (a) the sum of the following amount for each Mortgage Loan: (i) the Stated Principal Balance of such Mortgage Loan multiplied by (ii) a fraction, the numerator of which is the Net Mortgage Rate of such Mortgage Loan and the denominator of which is 14.710% over (b) the sum of the initial principal balances of the Lower Tier Interests containing the letters “A-IO” in their class designations.

(5)

The Class LT1-R Interest is the sole class of residual interest in the Subsidiary REMIC. It does not have an interest rate or a principal balance.

On each Distribution Date, the Securities Administrator shall first pay or charge as an expense of the Subsidiary REMIC all expenses of the Trust allocable to the Subsidiary REMIC for such Distribution Date.

On each Distribution Date, the Securities Administrator shall distribute the Interest Remittance Amount with respect to each of the Lower Tier Interests in the Subsidiary REMIC based on the above-described interest rates.

On each Distribution Date the Principal Remittance Amount shall be distributed (and Realized Losses shall be allocated) among the Lower Tier Interests in the Subsidiary REMIC in the following order of priority:

With respect to the PO Portion of such amounts, to the Class LT1-Pool-PO until the principal balance of such Interest is reduced to zero; and

With respect to the P&I Portion of such amounts, to the Class LT1-Pool Interest until the principal balance of such Interest is reduced to zero, and then to the Subsidiary REMIC Lower Tier Interests having the letters “A-IO” in their Class designation in ascending order of their numerical designation until the principal balance of each such Subsidiary REMIC Lower Tier Interest is reduced to zero.

For this purpose, the “P&I Portion” of any Mortgage Loan shall equal the following portion for any Mortgage Loan: (i) the Stated Principal Balance of such Mortgage Loan multiplied by (ii) a fraction, the numerator of which is the Net Mortgage Rate of such Mortgage Loan and the denominator of which is 14.710%. The “PO Portion” of any Mortgage Loan shall equal the Stated Principal Balance of such Mortgage Loan minus the P&I Portion of such Mortgage Loan.

On each Distribution Date, amounts distributable on the Class P Certificates shall be distributed on the Class LT1-P Interest.

Intermediate REMIC 1

The following table sets forth (or describes) the class designation, interest rate, and initial principal amount for each class of Lower Tier Interests in Intermediate REMIC 1:

The interest rate for this Lower Tier Interest for each Distribution Date (and the related Accrual Period) is a per annum rate equal to interest rate of its Corresponding Class of Certificates.

(2)

This interest shall have an initial principal balance equal to the initial principal balance of the Corresponding Class of Certificates for this interest.

(3)

This interest shall be an interest-only regular interest and shall be entitled to receive on any Distribution Date the amount distributable on such Distribution Date on the Class A-IO Certificates.

(4)

The Class LT3-Q Interest shall have an initial principal balance equal to the excess of (i) the aggregate Cut-off Date Principal Balance of the Mortgage Loans over (ii) the principal balance (as of the Closing Date) of each other regular interest in Intermediate REMIC 2, which right represents a Regular Interest in Intermediate REMIC 2. The Class LT3-Q Interest shall not accrue any interest on its principal balance. The Class LT3-Q Interest also comprises a notional component, which is also a Regular Interest in Intermediate REMIC 2. The notional component has a notional principal balance that at all times will equal the aggregate of the principal balances of the Regular Interests in Intermediate REMIC 1 (i.e., the Aggregate Loan Balance).

The Seller has entered into this Agreement in consideration for the purchase of the Mortgage Loans by the Depositor and has agreed to take the actions specified herein.

The Depositor, concurrently with the execution and delivery hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to the Trustee for the use and benefit of the Certificateholders, without recourse, all the right, title and interest of the Depositor in and to the Trust Fund. In addition, on or prior to the Closing Date, the Depositor shall direct the Trustee on behalf of the Trust Fund to enter into the Interest Rate Cap Agreement (and any related novation agreement) with the Interest Rate Cap Provider and the Depositor shall directly pay or cause to be paid on behalf of the Trust Fund the payments owed to the Interest Rate Cap Agreement Provider as of the Closing Date under the Interest Rate Cap Agreement.

In connection with such sale, the Depositor has delivered to, and deposited with, the Trustee or a Custodian, as its agent, the following documents or instruments with respect to each Mortgage Loan so assigned: (i) the original Mortgage Note, including any riders thereto, endorsed without recourse to the order of “HSBC Bank USA, National Association, as Trustee for certificateholders of Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series 2005-S4” or in blank, and showing to the extent available to the Seller an unbroken chain of endorsements from the original payee thereof to the Person endorsing it to the Trustee or in blank, as applicable, (ii) the original Mortgage and, if the related Mortgage Loan is a MOM Loan, noting the presence of the MIN and language indicating that such Mortgage Loan is a MOM Loan, which shall have been recorded (or if the original is not available, a copy), with evidence of such recording indicated thereon (or if clause (x) in the proviso below applies, shall be in recordable form), (iii) unless the Mortgage Loan is a MOM Loan, the assignment (either an original or a copy, which may be in the form of a blanket assignment if permitted in the jurisdiction in which the Mortgaged Property is located) to the Trustee or in blank of the Mortgage with respect to each Mortgage Loan in the name of “HSBC Bank USA, National Association, as Trustee for certificateholders of Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series 2005-S4,” which shall have been recorded (or if clause (x) in the proviso below applies, shall be in recordable form) (iv) an original or a copy of all intervening assignments of the Mortgage, if any, to the extent available to the Seller, with evidence of recording thereon, (v) the original policy of title insurance or mortgagee’s certificate of title insurance or commitment or binder for title insurance, if available, or a copy thereof, or, in the event that such original title insurance policy is unavailable, a photocopy thereof, or in lieu thereof, a current lien search on the related Mortgaged Property and (vi) originals or copies of all available assumption, modification or substitution agreements, if any; provided, however, that in lieu of the foregoing, the Seller may deliver the following documents, under the circumstances set forth below: (x) if any Mortgage, assignment thereof to the Trustee or intervening assignments thereof have been delivered or are being delivered to recording offices for recording and have not been returned in time to permit their delivery as specified above, the Depositor may deliver a true copy thereof with a certification by the Seller or the title company issuing the commitment for title insurance, on the face of such copy, substantially as follows: “Certified to be a true and correct copy of the original, which has been transmitted for recording”; and (y) in lieu of the Mortgage Notes relating to the Mortgage Loans identified in the list set forth in Exhibit J, the Depositor may deliver a lost note affidavit and indemnity and a copy of the original note, if available; and provided, further, that in the case of Mortgage Loans which have been prepaid in full after the Cut-Off Date and prior to the Closing Date, the Depositor, in lieu of delivering the above documents, may deliver to the Trustee a certification of a Authorized Servicer Representative to such effect and in such case shall deposit all amounts paid in respect of such Mortgage Loans, in the Distribution Account on the Closing Date. In the case of the documents referred to in clause (x) related above, the Depositor shall deliver such documents to the Trustee promptly after they are received. The Seller shall cause, at its expense, the Mortgage and intervening assignments, if any, and to the extent required in accordance with the foregoing, the assignment of the Mortgage to the Trustee to be submitted for recording promptly after the Closing Date; provided that the Seller need not cause to be recorded any assignment (a) in any jurisdiction under the laws of which, as evidenced by an Opinion of Counsel delivered by the Seller to the Trustee and the Rating Agencies, the recordation of such assignment is not necessary to protect the Trustee’s interest in the related Mortgage Loan or (b) if MERS is identified on the Mortgage or on a properly recorded assignment of the Mortgage as mortgagee of record solely as nominee for Seller and its successors and assigns. In the event that the Seller or the Depositor gives written notice to the Trustee that a court has recharacterized the sale of the Mortgage Loans as a financing, the Seller shall submit or cause to be submitted for recording as specified above or, should the Seller fail to perform such obligations within 30 days, the Trustee shall cause each such previously unrecorded assignment to be submitted for recording as specified above (unless, as specified above, such recording is not necessary) at the expense of the Trust pursuant to Section 9.05.

Section 2.02

Acceptance of the Mortgage Loans.

(a)

Based on the Initial Certifications received by it from the Custodian, the Trustee acknowledges receipt of, subject to the further review and exceptions reported by the Custodian pursuant to the procedures described below, the documents (or certified copies thereof) delivered to the Trustee or a Custodian on its behalf pursuant to Section 2.01 and declares that it holds and will continue to hold directly or through a custodian those documents and any amendments, replacements or supplements thereto and all other assets of the Trust Fund delivered to it in trust for the use and benefit of all present and future Holders of the Certificates. On the Closing Date, each Custodian on the Trustee’s behalf will deliver an Initial Certification in the form annexed hereto as Exhibit C-1, confirming whether or not it has received the Mortgage File for each Mortgage Loan, but without review of such Mortgage File, except to the extent necessary to confirm whether such Mortgage File contains the original Mortgage Note or a lost note affidavit and indemnity in lieu thereof. No later than 90 days after the Closing Date, each Custodian on the Trustee’s behalf shall, for the benefit of the Certificateholders, review each Mortgage File delivered to it and execute and deliver to the Seller and the Trustee an Interim Certification substantially in the form annexed hereto as Exhibit C-2. In conducting such review, each Custodian on the Trustee’s behalf will ascertain whether all required documents have been executed and received and whether those documents relate, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in Exhibit B to this Agreement, as supplemented (provided, however, that with respect to those documents described in subclauses (iv) and (vi) of Section 2.01, such obligations shall extend only to documents actually delivered pursuant to such subclauses). In performing any such review, each Custodian may conclusively rely on the purported due execution and genuineness of any such document and on the purported genuineness of any signature thereon. If a Custodian finds any document constituting part of the Mortgage File not to have been executed or received, or to be unrelated to the Mortgage Loans identified in Exhibit B, determined on the basis of the Mortgagor’s name, the original principal balance and the Mortgage Loan number, or to appear to be defective on its face, such Custodian shall include such information in the exception report attached to the Interim Certification. The Seller shall correct or cure any such defect or, if prior to the end of the second anniversary of the Closing Date, the Seller may substitute for the related Mortgage Loan a Replacement Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03 or shall deliver to the Trustee an Opinion of Counsel to the effect that such defect does not materially or adversely affect the interests of the Certificateholders in such Mortgage Loan within 60 days from the date of notice from the Trustee of the defect and if the Seller fails to correct or cure the defect or deliver such opinion within such period, the Seller will, subject to Section 2.03, within 90 days from the notification of the Trustee purchase such Mortgage Loan at the Purchase Price; provided, however, that if such defect relates solely to the inability of the Seller to deliver the Mortgage, assignment thereof to the Trustee, or intervening assignments thereof with evidence of recording thereon because such documents have been submitted for recording and have not been returned by the applicable jurisdiction, the Seller shall not be required to purchase such Mortgage Loan if the Seller delivers such documents promptly upon receipt, but in no event later than 360 days after the Closing Date.

(b)

No later than 180 days after the Closing Date, each Custodian on the Trustee’s behalf will review, for the benefit of the Certificateholders, the Mortgage Files and will execute and deliver or cause to be executed and delivered to the Seller and the Trustee, a Final Certification substantially in the form annexed hereto as Exhibit C-3. In conducting such review, each Custodian on the Trustee’s behalf will ascertain whether each document required to be recorded has been returned from the recording office with evidence of recording thereon and such Custodian on the Trustee’s behalf has received either an original or a copy thereof, as required in Section 2.01 (provided, however, that with respect to those documents described in subclauses (iv) and (vi) of Section 2.01, such obligations shall extend only to documents actually delivered pursuant to such subclauses). If a Custodian finds any document with respect to a Mortgage Loan has not been received, or to be unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in Exhibit B or to appear defective on its face, such Custodian shall note such defect in the exception report attached to the Final Certification and the Trustee shall promptly notify the Seller. The Seller shall correct or cure any such defect or, if prior to the end of the second anniversary of the Closing Date, the Seller may substitute for the related Mortgage Loan a Replacement Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03 or shall deliver to the Trustee an Opinion of Counsel to the effect that such defect does not materially or adversely affect the interests of Certificateholders in such Mortgage Loan within 60 days from the date of notice from the Trustee and if the Seller is unable within such period to correct or cure such defect, or to substitute the related Mortgage Loan with a Replacement Mortgage Loan or to deliver such opinion, the Seller shall, subject to Section 2.03, within 90 days from the notification of the Trustee, purchase such Mortgage Loan at the Purchase Price; provided, however, that if such defect relates solely to the inability of the Seller to deliver the Mortgage, assignment thereof to the Trustee or intervening assignments thereof with evidence of recording thereon, because such documents have not been returned by the applicable jurisdiction, the Seller shall not be required to purchase such Mortgage Loan, if the Seller delivers such documents promptly upon receipt, but in no event later than 360 days after the Closing Date.

(c)

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

(vii)

The representations and warranties set forth in Section 8 of the Mortgage Loan Purchase Agreement are true and correct as of the Closing Date.

(viii)

(c)

Upon discovery by any of the parties hereto of a breach of a representation or warranty set forth in Section 2.03(b)(viii), (ix) and (x) and Section 8 of the Mortgage Loan Purchase Agreement that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt written notice thereof to the other parties. The Seller hereby covenants with respect to the representations and warranties set forth in Section 2.03(b)(viii), (ix) and (x) and Section 8 of the Mortgage Loan Purchase Agreement, that within 90 days of the discovery of a breach of any representation or warranty set forth therein that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, it shall cure such breach in all material respects and, if such breach is not so cured, (i) prior to the second anniversary of the Closing Date, remove such Mortgage Loan (a “Deleted Mortgage Loan”) from the Trust Fund and substitute in its place a Replacement Mortgage Loan, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below; provided that any such substitution pursuant to (i) above or repurchase pursuant to (ii) above shall not be effected prior to the delivery to the Trustee of an Opinion of Counsel if required by Section 2.05 and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery to the Trustee of a Request for Release. The Seller shall promptly reimburse the Trustee for any expenses reasonably incurred by the Trustee in respect of enforcing the remedies for such breach. To enable the Servicer to amend the Mortgage Loan Schedule, the Seller shall, unless it cures such breach in a timely fashion pursuant to this Section 2.03, promptly notify the Trustee whether it intends either to repurchase, or to substitute for, the Mortgage Loan affected by such breach. With respect to the representations and warranties in Section 8 of the Mortgage Loan Purchase Agreement that are made to the best of the Seller’s knowledge, if it is discovered by any of the Depositor, the Seller, the Securities Administrator or the Trustee that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan, notwithstanding the Seller’s lack of knowledge with respect to the substance of such representation or warranty, the Seller shall nevertheless be required to cure, substitute for or repurchase the affected Mortgage Loan in accordance with the foregoing.

With respect to any Replacement Mortgage Loan or Loans, the Seller shall deliver to the related Custodian on behalf of the Trustee for the benefit of the related Certificateholders such documents and agreements as are required by Section 2.01. No substitution will be made in any calendar month after the Determination Date for such month. Scheduled Payments due with respect to Replacement Mortgage Loans in the Due Period related to the Distribution Date on which such proceeds are to be distributed shall not be part of the Trust Fund and will be retained by the Seller. For the month of substitution, distributions to Certificateholders will include the Scheduled Payment due on any Deleted Mortgage Loan for the related Due Period and thereafter the Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Servicer shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Replacement Mortgage Loan or Loans and shall deliver the amended Mortgage Loan Schedule to the Trustee, the Securities Administrator and the Master Servicer. Upon such substitution, the Replacement Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the Seller shall be deemed to have made with respect to such Replacement Mortgage Loan or Loans, as of the date of substitution, the representations and warranties set forth in Section 8 of the Mortgage Loan Purchase Agreement with respect to such Mortgage Loan. Upon any such substitution and the deposit into the Custodial Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, receipt by the Trustee of an Officer’s Certificate executed by the Seller stating that such substitution amounts have been so deposited, and receipt by the Trustee, or a Custodian on its behalf, of a Request for Release for such Mortgage Loan, the Trustee, or such Custodian on its behalf, shall release to the Seller the Mortgage File relating to such Deleted Mortgage Loan and held for the benefit of the related Certificateholders and shall execute and deliver at the Seller’s direction such instruments of transfer or assignment as have been prepared by the Seller, in each case without recourse, as shall be necessary to vest in the Seller, or its respective designee, title to the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03. Neither, the Trustee nor the related Custodian shall have any further responsibility with regard to such Mortgage File.

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

In the event that the Seller shall have repurchased a Mortgage Loan, the Purchase Price therefor shall be deposited into the Custodial Account maintained by the Servicer, on or before the Determination Date for the Distribution Date in the month following the month during which the Seller became obligated to repurchase or replace such Mortgage Loan and upon such deposit of the Purchase Price, the delivery of an Opinion of Counsel if required by Section 2.05 and the receipt of a Request for Release, the Trustee, or a Custodian on its behalf, shall release the related Mortgage File held for the benefit of the related Certificateholders to the Seller, and the Trustee shall execute and deliver at such Person’s direction the related instruments of transfer or assignment prepared by the Seller, in each case without recourse, as shall be necessary to transfer title from the Trustee for the benefit of the Certificateholders and transfer the Trustee’s interest to the Seller to any Mortgage Loan purchased pursuant to this Section 2.03. It is understood and agreed that the obligation under this Agreement of the Seller to cure, repurchase or replace any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedies against the Seller respecting such breach available to Certificateholders, the Depositor or the Trustee.

ARTICLE III

ADMINISTRATION AND SERVICING OF THE MORTGAGE LOANS

Section 3.01

The Servicer to Act as Servicer.

The Servicer shall service and administer the Mortgage Loans (other than any Mortgage Loans transferred to a Special Servicer pursuant to Section 3.24 hereof) on behalf of the Trust and in the best interest of and for the benefit of the Certificateholders (as determined by the Servicer in its reasonable judgment) in accordance with the terms of this Agreement and the Mortgage Loans and to the extent consistent with such terms and in accordance with and exercising the same care in performing those practices that the Servicer customarily employs and exercises in servicing and administering mortgage loans for its own account (including, compliance with all applicable federal, state and local laws).

To the extent consistent with the foregoing, the Servicer shall seek the timely and complete recovery of principal and interest on the Mortgage Notes related to the Mortgage Loans and shall waive a Prepayment Charge only under the following circumstances: (i) such waiver is standard and customary in servicing similar mortgage loans and (ii) either (A) such waiver is related to a default or reasonably foreseeable default and would, in the reasonable judgment of the Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related Mortgage Loan and, if such waiver is made in connection with a refinancing of the related Mortgage Loan, such refinancing is related to a default or a reasonably foreseeable default or (B) such waiver is made in connection with a refinancing of the related Mortgage Loan unrelated to a default or a reasonably foreseeable default where (x) the related Mortgagor has stated to the Servicer an intention to refinance the related Mortgage Loan and (y) the Servicer has concluded in its reasonable judgment that the waiver of such Prepayment Charge would induce such Mortgagor to refinance with the Servicer or (iii) the Servicer reasonably believes such Prepayment Charge is unenforceable in accordance with applicable law or the collection of such related Prepayment Charge would otherwise violate applicable law. If a Prepayment Charge is waived as permitted by meeting both of the standards described in clauses (i) and (ii)(B) above, then the Servicer is required to pay the amount of such waived Prepayment Charge (the “Servicer Prepayment Charge Payment Amount”), for the benefit of the Holders of the Class P Certificates, by depositing such amount into the Custodial Account within 90 days of notice or discovery of such waiver meeting the standard set forth in both clauses (i) and (ii)(B) above; provided, however, that the Servicer shall not waive more than 5% of the Prepayment Charges (by number of Prepayment Charges) set forth on the Prepayment Charge Schedule in accordance with clauses (i) and (ii)(B) above. Notwithstanding any other provisions of this Agreement, any payments made by the Servicer in respect of any waived Prepayment Charges pursuant to clauses (i) and (ii)(B) above and the preceding sentence shall be deemed to be paid outside of the Trust Fund.

Subject only to the above-described applicable servicing standards (the “Accepted Servicing Practices”) and the terms of this Agreement and of the respective Mortgage Loans, the Servicer shall have full power and authority, acting alone and/or through subservicers as provided in Section 3.03, to do or cause to be done any and all things that it may deem necessary or desirable in connection with such servicing and administration, including but not limited to, the power and authority, subject to the terms hereof (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 related Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages (but only in the manner provided herein), (iii) to collect any Insurance Proceeds and other Liquidation Proceeds, and (iv) subject to Section 3.09, to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan.

Without limiting the generality of the foregoing, the Servicer, in its own name or in the name of the Trust, the Depositor or the Trustee, is hereby authorized and empowered by the Trust, the Depositor and the Trustee, when the Servicer believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the Certificateholders 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 related Mortgaged Properties held for the benefit of the Certificateholders. The Servicer shall prepare and deliver to the Depositor and/or the Trustee such documents requiring execution and delivery by any or all of them as are necessary or appropriate to enable the Servicer to service and administer the Mortgage Loans. Upon receipt of such documents, the Depositor and/or the Trustee shall execute such documents and deliver them to the Servicer. In addition, the Trustee shall execute, at the written request of the Servicer, and furnish to the Servicer any special or limited powers of attorney agreeable to the Trustee and its counsel for each county in which a Mortgaged Property is located and other documents necessary or appropriate to enable the Servicer to carry out its servicing and administrative duties hereunder, provided such limited powers of attorney or other documents shall be prepared by the Servicer and submitted to the Trustee for review prior to execution.

In accordance with the standards of the first paragraph of this Section 3.01, the Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties relating to the Mortgage Loans in order to preserve the lien on the Mortgaged Property, which advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 4.04, and further as provided in Section 4.02. All costs incurred by the Servicer, if any, in effecting the payments of such taxes and assessments on the related Mortgaged Properties and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balance under the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

Section 3.02

Due-on-Sale Clauses; Assumption Agreements.

(a)

Except as otherwise provided in this Section 3.02, when any Mortgaged Property has been or is about to be conveyed by the Mortgagor, the Servicer shall to the extent that it has knowledge of such conveyance, enforce any due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent permitted under applicable law and governmental regulations, but only to the extent that such enforcement will not adversely affect or jeopardize coverage under any Required Insurance Policy. Notwithstanding the foregoing, the Servicer shall not be required to exercise such rights with respect to a Mortgage Loan if the Person to whom the related Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the terms and conditions contained in the Mortgage Note and Mortgage related thereto and the consent of the mortgagee under such Mortgage Note or Mortgage is not otherwise so required under such Mortgage Note or Mortgage as a condition to such transfer. In the event that the Servicer is prohibited by law from enforcing any such due-on-sale clause, or if coverage under any Required Insurance Policy would be adversely affected, or if nonenforcement is otherwise permitted hereunder, the Servicer is authorized, subject to Section 3.02(b), to take or enter into an assumption and modification agreement from or with the person to whom such property has been or is about to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, unless prohibited by applicable state law, the Mortgagor remains liable thereon, provided that the related Mortgage Loan shall continue to be covered (if so covered before the Servicer enters such agreement) by the applicable Required Insurance Policies. The Servicer, subject to Section 3.02(b), is also authorized with the prior approval of the insurers under any Required Insurance Policies to enter into a substitution of liability agreement with such Person, pursuant to which the original Mortgagor is released from liability and such Person is substituted as ▇▇▇▇▇▇▇▇▇ and becomes liable under the Mortgage Note. Notwithstanding the foregoing, the Servicer shall not be deemed to be in default under this Section 3.02(a) by reason of any transfer or assumption that the Servicer reasonably believes it is restricted by law from preventing.

(b)

Subject to the Servicer’s duty to enforce any due-on-sale clause to the extent set forth in Section 3.02(a), in any case in which a related Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage that requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the related Mortgage Loan, the Servicer shall prepare and deliver or cause to be prepared and delivered to the Trustee for signature and shall direct, in writing, the Trustee to execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person. In connection with any such assumption, no material term of the Mortgage Note (including, but not limited to, the Mortgage Rate, the amount of the Scheduled Payment, the Index, Gross Margin, Periodic Rate Cap, Adjustment Date, Maximum Mortgage Interest Rate or Minimum Mortgage Interest Rate and any other term affecting the amount or timing of payment on the related Mortgage Loan) may be changed. In addition, the substitute Mortgagor and the Mortgaged Property must be acceptable to the Servicer in accordance with the servicing standard set forth in Section 3.01. The Servicer shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the related Custodian the original of such substitution or assumption agreement, which in the case of the original shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Any fee collected by the Servicer for entering into an assumption or substitution of liability agreement will be retained by the Servicer as additional servicing compensation.

Section 3.03

Subservicers.

The Servicer shall perform all of its servicing responsibilities hereunder or may cause a subservicer to perform any such servicing responsibilities on its behalf, but the use by the Servicer of a subservicer shall not release the Servicer from any of its obligations hereunder with respect to the related Mortgage Loans. The Servicer shall pay all fees of each of its subservicers from its own funds, and a subservicer’s fee shall not exceed the Servicing Fee payable to the Servicer hereunder.

At the cost and expense of the Servicer, without any right of reimbursement from the Custodial Account, the Servicer shall be entitled to terminate the rights and responsibilities of a subservicer and arrange for any servicing responsibilities to be performed by a successor subservicer; provided, however, that nothing contained herein shall be deemed to prevent or prohibit the Servicer, at its option, from electing to service the related Mortgage Loans itself. In the event that the Servicer’s responsibilities and duties under this Agreement are terminated pursuant to Section 8.03, the Servicer shall at its own cost and expense terminate the rights and responsibilities of each subservicer with respect to the Mortgage Loans effective as of the date of the Servicer’s termination. The Servicer shall pay all fees, expenses or penalties necessary in order to terminate the rights and responsibilities of each subservicer from the Servicer’s own funds without reimbursement from the Trust Fund.

Notwithstanding the foregoing, the Servicer shall not be relieved of its obligations hereunder with respect to the Mortgage Loans and shall be obligated to the same extent and under the same terms and conditions as if it alone were servicing and administering the Mortgage Loans. The Servicer shall be entitled to enter into an agreement with a subservicer for indemnification of the Servicer by the subservicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

Any subservicing agreement and any other transactions or services relating to the Mortgage Loans involving a subservicer shall be deemed to be between such subservicer and the Servicer alone, and none of the Master Servicer, the Securities Administrator or the Trustee shall not have any obligations, duties or liabilities with respect to such subservicer including any obligation, duty or liability of the Master Servicer, the Securities Administrator or the Trustee to pay such subservicer’s fees and expenses or any differential in the amount of the servicing fee paid hereunder and the amount necessary to induce any successor servicer to act as successor servicer under this Agreement and the transactions provided for in this Agreement. For purposes of remittances to the Securities Administrator pursuant to this Agreement, the Servicer shall be deemed to have received a payment on a Mortgage Loan when a subservicer has received such payment.

Section 3.04

Documents, Records and Funds in Possession of the Servicer To Be Held for Trustee.

Notwithstanding any other provisions of this Agreement, the Servicer shall transmit to the Trustee, or a Custodian on its behalf, as required by this Agreement all documents and instruments in respect of a related Mortgage Loan coming into the possession of the Servicer from time to time and shall account fully to the Master Servicer for any funds received by the Servicer or that otherwise are collected by the Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any such Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, the Servicer in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, including but not limited to, any funds on deposit in the Custodial Account, shall be held by the Servicer for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. The Servicer also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the Custodial Account, the Distribution Account or in any Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, or assert by legal action or otherwise any claim or right of set off against any Mortgage File or any funds collected on, or in connection with, a Mortgage Loan, except, however, that the Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Servicer under this Agreement.

Section 3.05

Maintenance of Hazard Insurance.

(a)

The Servicer shall cause to be maintained for each Mortgage Loan hazard insurance with extended coverage on the Mortgaged Property in an amount which is at least equal to the lesser of (i) the Stated Principal Balance of such Mortgage Loan and (ii) the amount necessary to fully compensate for any damage or loss to the improvements that are a part of such property on a replacement cost basis, in each case in an amount not less than such amount as is necessary to avoid the application of any coinsurance clause contained in the related hazard insurance policy. The Servicer shall also cause to be maintained hazard insurance with extended coverage on each REO Property in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements which are a part of such REO Property and (ii) the Stated Principal Balance of the related Mortgage Loan at the time it became an REO Property. The Servicer will comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any such hazard policies. Any amounts collected by the Servicer under any such policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or amounts to be released to the Mortgagor in accordance with the procedures that the Servicer would follow in servicing loans held for its own account, subject to the terms and conditions of the related Mortgage and Mortgage Note and in accordance with the servicing standard set forth in Section 3.01) shall be deposited in the Custodial Account, subject to withdrawal pursuant to Section 4.02. Any cost incurred by the Servicer in maintaining any such insurance shall not, for the purpose of calculating distributions to Certificateholders, be added to the Stated Principal Balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If the Mortgaged Property or REO Property is at any time in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards and flood insurance has been made available, the Servicer shall cause to be maintained a flood insurance policy in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the Stated Principal Balance of the related Mortgage Loan and (ii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program (assuming that the area in which such Mortgaged Property is located is participating in such program).

In the event that the Servicer shall obtain and maintain a blanket policy with an insurer having a General Policy Rating of B:VI or better in Best’s Key Rating Guide (or such other rating that is comparable to such rating) insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations as set forth in the first two sentences of this Section 3.05, it being understood and agreed that such policy may contain a deductible clause, in which case the Servicer shall, in the event that there shall not have been maintained on the related Mortgaged Property or REO Property a policy complying with the first two sentences of this Section 3.05, and there shall have been one or more losses which would have been covered by such policy, deposit to the Custodial Account from its own funds the amount not otherwise payable under the blanket policy because of such deductible clause. In connection with its activities as administrator and servicer of the Mortgage Loans, the Servicer agrees to prepare and present, on behalf of itself, the Trustee and Certificateholders, claims under any such blanket policy in a timely fashion in accordance with the terms of such policy.

(b)

The Servicer shall keep in force during the term of this Agreement a policy or policies of insurance covering errors and omissions for failure in the performance of the Servicer’s obligations under this Agreement, which policy or policies shall be in such form and amount that would meet the requirements of ▇▇▇▇▇▇ ▇▇▇ or Freddie Mac if it were the purchaser of the related Mortgage Loans, unless the Servicer has obtained a waiver of such requirements from ▇▇▇▇▇▇ ▇▇▇ or Freddie Mac. The Servicer shall provide the Master Servicer, upon request, with copies of such insurance policies and fidelity bond. The Servicer shall also maintain a fidelity bond in the form and amount that would meet the requirements of ▇▇▇▇▇▇ ▇▇▇ or Freddie Mac, unless the Servicer has obtained a waiver of such requirements from ▇▇▇▇▇▇ ▇▇▇ or Freddie Mac. The Servicer shall be deemed to have complied with this provision if an Affiliate of the Servicer has such errors and omissions and fidelity bond coverage and, by the terms of such insurance policy or fidelity bond, the coverage afforded thereunder extends to the Servicer. Any such errors and omissions policy and fidelity bond shall by its terms not be cancelable without thirty days’ prior written notice to the Master Servicer. The Servicer shall also cause its subservicers to maintain a policy of insurance covering errors and omissions and a fidelity bond which would meet such requirements.

Section 3.06

Presentment of Claims and Collection of Proceeds.

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

Section 3.07

Maintenance of Insurance Policies.

The Servicer shall not take any action that would result in noncoverage under any applicable Insurance Policy of any loss which, but for the actions of the Servicer would have been covered thereunder. The Servicer shall use its best efforts to keep in force and effect (to the extent that the related Mortgage Loan requires the Mortgagor to maintain such insurance), any applicable Insurance Policy. The Servicer shall not cancel or refuse to renew any Insurance Policy that is in effect at the date of the initial issuance of the Mortgage Note and is required to be kept in force hereunder.

Section 3.08

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 Financial Institution Bond Form 24 Fidelity Bond American International Specialty Lines Insurance Policy form (“43350 12/90”) or otherwise in a form acceptable to ▇▇▇▇▇▇ ▇▇▇ or Freddie Mac, and shall protect and insure the Servicer against losses, including forgery, theft embezzlement, fraud, errors and omissions and negligent acts of the Servicer Employees. Each 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 3.08 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 ▇▇▇▇▇▇ ▇▇▇.

Section 3.09

Realization Upon Defaulted Mortgage Loans; Determination of Excess Liquidation Proceeds and Realized Losses; Repurchases of Certain Mortgage Loans.

(a)

(i)

The Servicer shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. With respect to such of the Mortgage Loans as come into and continue in default, the Servicer will decide whether to (1) foreclose upon the Mortgaged Properties securing such Mortgage Loans, (2) write off the unpaid principal balance of the Mortgage Loans as bad debt, (3) take a deed in lieu of foreclosure, (4) accept a short sale (a payoff of the Mortgage Loan for an amount less than the total amount contractually owed in order to facilitate a sale of the Mortgaged Property by the Mortgagor) or permit a short refinancing (a payoff of the Mortgage Loan for an amount less than the total amount contractually owed in order to facilitate refinancing transactions by the Mortgagor not involving a sale of the Mortgaged Property), (5) arrange for a repayment plan, or (6) agree to a modification in accordance with this Agreement. In connection with such foreclosure or other conversion, the Servicer shall follow such practices and procedures as it shall deem necessary or advisable and as shall be normal and usual in its general mortgage servicing activities and the requirements of the insurer under any Required Insurance Policy; provided that the Servicer shall not be required to expend its own funds in connection with any foreclosure or towards the restoration of any property unless it shall determine (x) that such restoration and/or foreclosure will increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself of such expenses and (y) that such expenses will be recoverable to it through Liquidation Proceeds (respecting which it shall have priority for purposes of withdrawals from the Custodial Account pursuant to Section 4.02). The Servicer shall be responsible for all other costs and expenses incurred by it in any such proceedings; provided that such costs and expenses shall be Servicing Advances and that it shall be entitled to reimbursement thereof from the proceeds of liquidation of the related Mortgaged Property, or as otherwise provided in Section 4.02. If the Servicer has knowledge that a Mortgaged Property that the Servicer is contemplating acquiring in foreclosure or by deed-in-lieu of foreclosure is located within a one-mile radius of any site with environmental or hazardous waste risks known to the Servicer, the Servicer shall, prior to acquiring the Mortgaged Property, consider such risks and only take action in accordance with its established environmental review procedures.

(ii)

Notwithstanding anything to the contrary contained in this Agreement (other than with respect to any Mortgage Loan that is transferred to a Special Servicer pursuant to Section 3.24 hereof), with respect to any Mortgage Loan that is one hundred twenty (120) days Delinquent, the Servicer shall obtain a broker’s price opinion with respect to the related Mortgaged Property and shall use all reasonable efforts to obtain a total indebtedness balance (including, but not limited to, unpaid principal, interest, escrows, taxes and expenses) for any related senior lien. The cost of obtaining any such broker’s price opinion shall be reimbursable to the related Servicer as a Servicing Advance. After obtaining the related broker’s price opinion, the Servicer will determine within sixty 60 days of the date that such Mortgage Loan is one hundred twenty (120) days Delinquent whether any Significant Net Recovery is possible through foreclosure proceedings or other liquidation of the related Mortgaged Property and provide written notice to the Securities Administrator, the Master Servicer and the Credit Risk Manager of such decision. If the Servicer determines that (x) no Significant Net Recovery is possible or (y) the potential Net Recoveries are anticipated to be an amount, determined by the Servicer in its good faith judgment and in light of other mitigating circumstances, that is insufficient to warrant proceeding through foreclosure or other liquidation of the related Mortgaged Property, it may, at its discretion, charge off such delinquent Mortgage Loan in accordance with this Section 3.09(a)(iii) and (iv) below.

(iii)

With respect to any Mortgage Loan, if the Servicer determines based on the broker’s price opinion obtained under the immediately preceding paragraph above and other relevant considerations that (x) no Significant Net Recovery is possible through foreclosure proceedings or other liquidation of the related Mortgaged Property or (y) the potential Net Recoveries are anticipated to be an amount, determined by the Servicer in its good faith judgment and in light of other mitigating circumstances, that is insufficient to warrant proceeding through foreclosure or other liquidation of the related Mortgaged Property, it may, at its discretion, charge off the related Mortgage Loan at the time such Mortgage Loan becomes 180 days Delinquent and provide written notice of such charge off to the Credit Risk Manager, the Master Servicer and the Securities Administrator. Once a Mortgage Loan has been charged off, the Servicer will discontinue making Advances, the Servicer will not be entitled to any additional servicing compensation (except as described in paragraph (a)(iv) of this Section 3.09), the Charged Off Loan will give rise to a Realized Loss, and the Servicer will follow the procedures described in paragraph (a)(iv) below. If the Servicer subsequently determines that (x) a Significant Net Recovery is possible through foreclosure proceedings or other liquidation of the Mortgaged Property and (y) the potential Net Recoveries are anticipated to be an amount, determined by the Servicer in its good faith judgment and in light of other mitigating circumstances, that is sufficient to warrant proceeding through foreclosure or other liquidation of the related Mortgaged Property, the Servicer may continue to make Advances or Servicing Advances on the related Mortgage Loan that has become 180 days delinquent and, will notify the Credit Risk Manager, the Securities Administrator and the Master Servicer in writing of that decision.

(iv)

Any Mortgage Loan that becomes a Charged Off Loan may continue to be serviced by the Servicer for the Certificateholders using Special Servicing. The Servicer will accrue, but not be entitled to any Servicing Fees and reimbursement of expenses in connection with such Charged Off Loans, except to the extent of funds available from the aggregate amount of recoveries on all Charged Off Loans. Such aggregate recovery amounts on Charged Off Loans shall be paid to the Servicer first, as reimbursement of any outstanding and unpaid expenses, and second, as any accrued and unpaid Servicing Fees. The Servicer will only be entitled to previously accrued Servicing Fees and expenses on any such Charged Off Loans. The Servicer will not be entitled to receive any future unaccrued Servicing Fees or expenses from collections on such Charged Off Loans. Any Charged Off Loan serviced by the Servicer using Special Servicing shall be so serviced until the Release Date described below. Any Net Recoveries on such Charged Off Loans received prior to the Release Date will be included in the Principal Remittance Amount. On the date (the “Release Date”) which is no more than six months after the date on which the Servicer begins servicing any Charged Off Loans using Special Servicing, unless specific Net Recoveries are anticipated by the Servicer on a particular Charged Off Loan (in which case the Release Date will be delayed until all such specific anticipated Net Recoveries are received and the Servicer will provide written notice thereof to the Credit Risk Manager, the Master Servicer and the Securities Administrator), such Charged Off Loan will be released from the Trust Fund, will no longer be an asset of any REMIC, and will be transferred to the Class X-2 Certificateholders, without recourse, and thereafter (i) those Holders will be entitled to any amounts subsequently received in respect of any such Released Loans, (ii) the Majority Class X-2 Certificateholder may designate any servicer to service any such Released Loan pursuant to an agreement between such servicer and the Majority Class X-2 Certificateholder and (iii) the Majority Class X-2 Certificateholder may sell any such Released Loan to a third party. Notwithstanding the previous sentence, if at any time after a Mortgage Loan has been Charged Off and prior to six months after the date on which the Servicer begins servicing such Charged Off Loan using Special Servicing, the Servicer determines that there will not be any Net Recoveries on such Charged Off Loan under any circumstances, the Servicer may release such Charged Off Loan to the Majority Class X-2 Certificateholder prior to the Release Date in accordance with the provisions set forth in the previous sentence and the Servicer will provide written notice thereof to the Credit Risk Manager, the Master Servicer and the Securities Administrator. The Master Servicer shall track collections received by the Servicer on any Charged Off Loans based upon loan level data provided to the Master Servicer by the Servicer on the date such reports are required to be delivered to the Master Servicer pursuant to Section 4.03 hereof in a report in the form of Exhibit N hereto, identifying the Charged Off Loans as of the related Due Period that the Servicer will continue to service until the related Release Date using Special Servicing. On each Distribution Date, the Master Servicer shall verify, based on the recovery and expense information provided by the Servicer, (i) the aggregate amount of accrued and unpaid Servicing Fees to be paid to the Servicer and expenses to be reimbursed to the Servicer on such Charged Off Loans as of the related Due Period and (ii) the amount of Net Recoveries on such Charged Off Loans for such Distribution Date. The Master Servicer shall be entitled to rely, without independent verification, on the loan level data provided by the Servicer that identifies the recovery amounts and the outstanding and unpaid expenses on any Charged Off Loan in order to verify the amount in clause (ii) of the previous sentence. The Master Servicer will be responsible for independently verifying the aggregate amount of accrued and unpaid Servicing Fees described in clause (i) of the second preceding sentence to be paid to the Servicer.

(v)

The Majority Class X-2 Certificateholder, at its option, may (but is not obligated to), upon notice in writing to the Credit Risk Manager, the Trustee, the Master Servicer and the Securities Administrator, repurchase from the Trust Fund, (a) any Mortgage Loan that is Delinquent in payment by three or more Scheduled Payments or (b) any Mortgage Loan with respect to which there has been initiated legal action or other proceedings for the foreclosure of the related Mortgaged Property either judicially or non-judicially. If it elects to make any such repurchase, the Majority Class X-2 Certificateholder shall repurchase such Mortgage Loan with its own funds at a price equal to the Purchase Price for such Mortgage Loan, and shall remit such Purchase Price to the Securities Administrator for deposit in the Distribution Account. The Majority Class X-2 Certificateholder may designate any servicer to service any such Mortgage Loan purchased from the Trust pursuant to a separate agreement between such servicer and the Majority Class X-2 Certificateholder.

(vi)

With respect to any REO Property, the deed or certificate of sale shall be taken in the name of the Trustee for the benefit of the Certificateholders (or the Trustee’s nominee on behalf of the Certificateholders). The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. The Servicer shall ensure that the title to such REO Property references this Agreement and the Trustee’s capacity hereunder. Pursuant to its efforts to sell such REO Property, the Servicer shall either itself or through an agent selected by the Servicer protect and conserve such REO Property in the same manner and to such extent as is customary in the locality where such REO Property is located and may, incident to its conservation and protection of the interests of the Certificateholders, rent the same, or any part thereof, as the Servicer deems to be in the best interest of the Servicer and the Certificateholders for the period prior to the sale of such REO Property. The Servicer shall prepare for and deliver to the Master Servicer a statement with respect to each REO Property that has been rented showing the aggregate rental income received and all expenses incurred in connection with the management and maintenance of such REO Property at such times as is necessary to enable the Securities Administrator to comply with the reporting requirements of the REMIC Provisions. The net monthly rental income, if any, from such REO Property shall be deposited in the Custodial Account no later than the close of business on each Determination Date. The Servicer shall perform the tax reporting and withholding related to foreclosures, abandonments and cancellation of indebtedness income as specified by Sections 6050H, 6050J and 6050P of the Code by preparing and filing such tax and information returns, as may be required.

In the event that the Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to three years after its acquisition by the Trust Fund or, at the expense of the Trust Fund, request from the Internal Revenue Service more than 60 days prior to the day on which such three-year period would otherwise expire, an extension of the three-year grace period. The Trustee shall be supplied with an Opinion of Counsel (such opinion not to be an expense of the Trustee or the Trust Fund) to the effect that the holding by the Trust Fund of such Mortgaged Property subsequent to such three-year period will not result in the imposition of taxes on “prohibited transactions” of any REMIC as defined in section 860F of the Code or cause any REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding, in which case the Trust Fund may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel). Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of section 860G(a)(8) of the Code or (ii) subject any REMIC to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under section 860G(c) of the Code or otherwise, unless the Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

The decision of the Servicer to foreclose on a defaulted Mortgage Loan shall be subject to a determination by the Servicer that the proceeds of such foreclosure would exceed the costs and expenses of bringing such a proceeding. The income earned from the management of any Mortgaged Properties acquired through foreclosure or other judicial proceeding, net of reimbursement to the Servicer for expenses incurred (including any property or other taxes) in connection with such management and net of unreimbursed Servicing Fees, Master Servicing Fees, Advances, Servicing Advances and any management fee paid or to be paid with respect to the management of such Mortgaged Property, shall be applied to the payment of principal of, and interest on, the related defaulted Mortgage Loans (with interest accruing as though such Mortgage Loans were still current) and all such income shall be deemed, for all purposes in the Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the Custodial Account. To the extent the income received during a Prepayment Period is in excess of the amount attributable to amortizing principal and accrued interest at the related Mortgage Rate on the related Mortgage Loan, such excess shall be considered to be a partial Principal Prepayment for all purposes hereof.

The Liquidation Proceeds from any liquidation of a Mortgage Loan, net of any payment to the Servicer as provided above, shall be deposited in the Custodial Account on the next succeeding Determination Date following receipt thereof for distribution on the related Distribution Date, except that any Excess Liquidation Proceeds shall be retained by the Servicer as additional servicing compensation.

The proceeds of any Liquidated Loan, as well as any recovery resulting from a partial collection of Liquidation Proceeds or any income from an REO Property, shall be applied in the following order of priority: first, to reimburse the Servicer for any related unreimbursed Servicing Advances, Master Servicing Fees and Servicing Fees, pursuant to Section 4.02 or this Section 3.09; second, to reimburse the Servicer and the Master Servicer for any unreimbursed Advances, pursuant to Section 4.02 or this Section 3.09; third, to accrued and unpaid interest (to the extent no Advance has been made for such amount) on the Mortgage Loan or related REO Property, at the Net Mortgage Rate to the first day of the month in which such amounts are required to be distributed; and fourth, as a recovery of principal of the Mortgage Loan.

(b)

On each Determination Date, the Servicer shall determine the respective aggregate amounts of Excess Liquidation Proceeds and Realized Losses, if any, with respect to any Mortgage Loan for the related Prepayment Period and report such amounts to the Master Servicer pursuant to Section 4.03.

(c)

The Servicer has no intent to foreclose on any Mortgage Loan based on the delinquency characteristics as of the Closing Date; provided, however, that the foregoing does not prevent the Servicer from initiating foreclosure proceedings on any date hereafter if the facts and circumstances of such Mortgage Loans including delinquency characteristics in the Servicer’s discretion so warrant such action.

Section 3.10

Servicing Compensation.

As compensation for its activities hereunder, the Servicer shall be entitled to retain or withdraw from the Custodial Account out of each payment of interest on each Mortgage Loan included in the Trust Fund an amount equal to the Servicing Fee. In addition, the Servicer shall be entitled to recover unpaid Servicing Fees out of Liquidation Proceeds, Insurance Proceeds or condemnation proceeds to the extent permitted by Section 4.02. In connection with the servicing of any Special Serviced Mortgage Loan, the Special Servicer shall receive the Servicing Fee for such Special Serviced Mortgage Loan as its compensation and the Servicer shall no longer be entitled to the Servicing Fee with respect to such Mortgage Loan.

Additional servicing compensation with respect to Mortgage Loans in the form of any Excess Liquidation Proceeds, assumption fees, late payment charges, insufficient funds charges and ancillary income to the extent such fees or charges are received by the Servicer, all income and gain net of any losses realized from Permitted Investments with respect to funds in or credited to the Custodial Account shall be retained by the Servicer to the extent not required to be deposited in the Custodial Account pursuant to Section 4.02. The Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including payment of any premiums for hazard insurance, as required by Section 3.05 and maintenance of the other forms of insurance coverage required by Section 3.07) and shall not be entitled to reimbursement therefor except as specifically provided in Section 4.02.

Section 3.11

REO Property.

(a)

If such report discloses exceptions that are material, the Master Servicer shall advise the Trustee whether such exceptions have been or are susceptible of cure, and shall take prompt action to do so.

Section 3A.11. Obligation of the Master Servicer in Respect of Prepayment Interest Shortfalls. In the event that the Servicer fails to perform on any Remittance Date its obligations pursuant to Section 5.02, the Master Servicer shall remit to the Securities Administrator not later than the Distribution Date an amount equal to the lesser of (i) the aggregate amounts required to be paid by the Servicer with respect to Prepayment Interest Shortfalls attributable to Principal Prepayments on the related Mortgage Loans for the related Distribution Date, and not so paid by the Servicer and (ii) the Master Servicing Fee for such Distribution Date, without reimbursement therefor.

Section 3A.12. Advances by the Master Servicer. If the Servicer fails to remit any Advance required to be made pursuant to Section 5.01, the Master Servicer shall itself make, as Successor Servicer, or shall cause any other Successor Servicer to make, such Advance. If the Master Servicer determines that an Advance is required, it shall on the Business Day preceding the related Distribution Date immediately following such Remittance Date remit to the Securities Administrator from its own funds (or funds advanced by the Servicer) for deposit in the Distribution Account immediately available funds in an amount equal to such Advance. The Master Servicer shall be entitled to be reimbursed for all Advances made by it. Notwithstanding anything to the contrary herein, in the event the Master Servicer determines in its reasonable judgment that an Advance is a Nonrecoverable Advance, the Master Servicer shall be under no obligation to make such Advance. If the Master Servicer determines that an Advance is a Nonrecoverable Advance, it shall, on or prior to the related Distribution Date, deliver an Officer’s Certificate to the Trustee and the Securities Administrator to such effect.

Section 3A.13. Merger or Consolidation. Any Person into which the Master Servicer may be merged or consolidated, or any Person resulting from any merger, conversion, other change in form or consolidation to which the Master Servicer shall be a party, or any Person succeeding to the business of the Master Servicer, shall be the successor to the Master Servicer hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or resulting Person to the Master Servicer or its Affiliate whose primary business is the servicing of conventional residential mortgage loans shall be a Person that meets the criteria for qualification as the Servicer as provided in this Agreement.

Section 4.01

Collection of Mortgage Loan Payments; Custodial Account.

(a)

The Servicer shall make reasonable efforts in accordance with Accepted Servicing Practices to collect all payments called for under the terms and provisions of the related Mortgage Loans to the extent such procedures shall be consistent with this Agreement and the terms and provisions of any related Required Insurance Policy. Consistent with the foregoing, the Servicer may in its discretion (i) waive any late payment charge and (ii) extend the due dates for payments due on a Mortgage Note for a Mortgage Loan for a period not greater than 180 days; provided, however no such extension shall be materially adverse to the Certificateholders. In the event of any such arrangement, the Servicer shall make Advances on the related Mortgage Loan during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements, and shall be entitled to reimbursement therefor in accordance with Section 5.01. The Servicer shall not be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law. In addition, if (x) a Mortgage Loan is in default or default is imminent or (y) the Servicer delivers to the Trustee a REMIC Opinion, the Servicer may, (A) amend the related Mortgage Note to reduce the Mortgage Rate applicable thereto and (B) amend any Mortgage Note for a Mortgage Loan to extend to the maturity thereof.

(b)

The Servicer shall establish and maintain a segregated Custodial Account (which shall at all times be an Eligible Account) with a depository institution in the name of the Servicer for the benefit of the Trustee on behalf of the Certificateholders and designated “HSBC Bank USA, National Association, as trustee for registered holders of Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series 2005-S4”. On behalf of the Trust Fund, the Servicer shall deposit or cause to be deposited in the clearing account in which it customarily deposits payments and collection on Mortgage Loans in connection with its mortgage loan servicing activities on a daily basis and in no event more than one Business Day after the Servicer’s receipt thereof, and shall thereafter deposit in the Custodial Account, in no event more than two Business Days after the Servicer’s receipt thereof, except as otherwise specifically provided herein, the following payments and collections remitted by subservicers or received by it in respect of the Mortgage Loans subsequent to the Cut-off Date (other than in respect of principal and interest due on the related Mortgage Loans on or before the Cut-off Date) and the following amounts required to be deposited hereunder:

(i)

all payments on account of principal, including Principal Prepayments and Subsequent Recoveries, on the Mortgage Loans;

(ii)

all payments on account of interest on the Mortgage Loans net of the related Servicing Fee permitted under Section 3.10;

(iii)

all Liquidation Proceeds, Insurance Proceeds and condemnation proceeds with respect to the Mortgage Loans, other than proceeds to be applied to the restoration or repair of the related Mortgaged Properties or released to the Mortgagor in accordance with the Servicer’s normal servicing procedures;

(iv)

any amount required to be deposited by the Servicer pursuant to Section 4.01(c) in connection with any losses on Permitted Investments;

(v)

any amounts required to be deposited by the Servicer pursuant to Section 3.05;

(vi)

any amounts paid by an Advance Financing Person in respect of Advances or Servicing Advances;

(vii)

any Prepayment Charges collected by the Servicer in connection with the Principal Prepayment of any of the Mortgage Loans and any Servicer Prepayment Charge Payment Amounts; and

(viii)

any other amounts required to be deposited hereunder.

The foregoing requirements for deposit by the Servicer 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 late payment charges or assumption fees, if collected, need not be deposited by the Servicer. In the event that the Servicer shall deposit any amount not required to be deposited and not otherwise subject to withdrawal pursuant to Section 4.02, it may at any time withdraw or direct the institution maintaining the Custodial Account, to withdraw such amount from the Custodial Account, any provision herein to the contrary notwithstanding. Such withdrawal or direction may be accomplished by delivering written notice thereof to the institution maintaining the Custodial Account, that describes the amounts deposited in error in the Custodial Account. The Servicer shall maintain adequate records with respect to all withdrawals made pursuant to this Section. All funds deposited in the Custodial Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 4.02.

(c)

The institution that maintains the Custodial Account or other authorized entity shall invest the funds in the Custodial Account, in the manner directed by the Servicer, in Permitted Investments which shall mature not later than the next succeeding Remittance Date and shall not be sold or disposed of prior to its maturity. All such Permitted Investments shall be made in the name of the Trustee, for the benefit of the Certificateholders. All income and gain net of any losses realized from any such investment shall be for the benefit of the Servicer as servicing compensation and shall be remitted to it monthly as provided herein. The amount of any losses incurred in the Custodial Account in respect of any such investments shall be deposited by the Servicer into the Custodial Account immediately as realized, out of its own funds.

(d)

The Servicer shall give at least 30 days advance notice to the Trustee, the Master Servicer, the Securities Administrator, the Seller, each Rating Agency and the Depositor of any proposed change of location of the Custodial Account prior to any change thereof.

Section 4.02

Permitted Withdrawals From the Custodial Account.

(a)

The Servicer may from time to time make withdrawals from the Custodial Account for the following purposes:

(i)

to pay itself (to the extent not previously paid to or withheld by the Servicer), as servicing compensation in accordance with Section 3.10, that portion of any payment of interest that equals the Servicing Fee for the period with respect to which such interest payment was made, and, as additional servicing compensation, those other amounts set forth in Section 3.10;

(ii)

to reimburse the Servicer or an Advance Financing Person for (A) any unreimbursed Advances to the extent of amounts received which represent late recoveries of payments of principal and/or interest (net of the related Servicing Fees), Liquidation Proceeds and Insurance Proceeds on the Mortgage Loans with respect to which such Advances were made in accordance with the provisions of Section 5.01; and (B) any unreimbursed Advances with respect to the final liquidation of a Mortgage Loan that are Nonrecoverable Advances, but only to the extent that late recoveries of payments of principal and/or interest, Liquidation Proceeds and Insurance Proceeds received with respect to such Mortgage Loan are insufficient to reimburse the Servicer or an Advance Financing Person for such unreimbursed Advances or (C) subject to Section 4.02(b), any unreimbursed Advances to the extent of Amounts Held For Future Distribution funds held in the Custodial Account that were not included in the Available Distribution Amount for the preceding Distribution Date;

(iii)

to reimburse the Servicer or an Advance Financing Person for any Nonrecoverable Advances (other than with respect to final liquidation of a Mortgage Loan as provided for in clause (ii) above);

(iv)

to reimburse the Servicer from Insurance Proceeds for Insured Expenses covered by the related Insurance Policy;

(v)

to pay the Servicer any unpaid Servicing Fees and to reimburse it or any Advance Financing Person for any unreimbursed Servicing Advances, provided, however, that the Servicer’s or such Advance Financing Person’s right to reimbursement for Servicing Advances pursuant to this subclause (v) with respect to any Mortgage Loan shall be limited to amounts received on particular Mortgage Loan(s) (including, for this purpose, late recoveries of payments of principal and/or interest, Liquidation Proceeds, Insurance Proceeds, condemnation proceeds and purchase and repurchase proceeds) that represent late recoveries of the payments for which such Servicing Advances were made;

(vi)

to pay to the Seller, the Depositor or the Majority Class X-2 Certificateholder, as applicable, with respect to each Mortgage Loan or property acquired in respect thereof that has been purchased pursuant to Section 2.02, 2.03 or 3.23, all amounts received thereon and not taken into account in determining the related Stated Principal Balance of such repurchased Mortgage Loan;

(vii)

to pay any expenses recoverable by the Servicer pursuant to Section 7.04;

(viii)

to withdraw any amount deposited in the Custodial Account and not required to be deposited therein; and

(ix)

In addition, no later than 12:00 p.m. Eastern time on the Remittance Date, the Servicer shall withdraw from the Custodial Account and remit to the Securities Administrator (a) all amounts deposited in the Custodial Account as of the close of business on the last day of the related Due Period (net of charges against or withdrawals from the Custodial Account pursuant to this Section 4.02), plus (b) all Advances, if any, which the Servicer is obligated to make pursuant to Section 5.01, minus (c) any amounts attributable to Principal Prepayments, Liquidation Proceeds, Insurance Proceeds or condemnation proceeds received after the applicable Prepayment Period, which amounts shall be remitted on the following Remittance Date, together with any Compensating Interest required to be deposited in the Custodial Account in connection with such Principal Prepayment in accordance with Section 5.02, and minus (d) any amounts attributable to Scheduled Payments collected but due on a Due Date or Due Dates subsequent to the first day of the month in which such Remittance Date occurs, which amounts shall be remitted on the Remittance Date next succeeding the Due Date related to such Scheduled Payment.

With respect to any remittance received by the Securities Administrator after the Business Day on which such payment was due, the Securities Administrator shall send written notice thereof to the Servicer. The Servicer shall pay to the Securities Administrator interest on any such late payment by the Servicer at an annual rate equal to the Prime Rate (as defined in The Wall Street Journal) plus one percentage point, but in no event greater than the maximum amount permitted by applicable law. Such interest shall be paid by the Servicer to the Securities Administrator on the date such late payment is made and shall cover the period commencing with the day following the Business Day on which such payment was due and ending with the Business Day on which such payment is made, both inclusive. The payment by the Servicer of any such interest, or the failure of the Securities Administrator to notify the Servicer of such interest, shall not be deemed an extension of time for payment or a waiver any Servicer Default by the Servicer.

The Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the Custodial Account pursuant to subclauses (i), (ii), (iv), (v) and (vi) above. Prior to making any withdrawal from a Custodial Account pursuant to subclause (iii), the Servicer shall deliver to the Master Servicer an Officer’s Certificate of a Authorized Servicer Representative indicating the amount of any previous Advance or Servicing Advance determined by the Servicer to be a Nonrecoverable Advance and identifying the related Mortgage Loan(s), and their respective portions of such Nonrecoverable Advance.

(b)

Notwithstanding the foregoing, any Amounts Held For Future Distribution withdrawn by the Servicer as permitted in Section 4.02(a)(ii) in reimbursement of Advances previously made by the Servicer shall be appropriately reflected in the Servicer’s records and replaced by the Servicer by deposit in the Custodial Account, no later than the close of business on any future Remittance Date on which the funds on deposit in the Custodial Account shall be less than the amount required to be remitted to the Trust on such Remittance Date; provided, however that if the rating of the Servicer (including any Successor Servicer) is less than “BBB”, the Servicer shall be required to replace such funds by deposit to the Distribution Account, no later than the close of business on the Remittance Date immediately following the Due Period or Prepayment Period for which such amounts relate.

Section 4.03

Reports by Servicer.

Not later than the tenth (10th) calendar day of each month (or if such tenth calendar day is not a Business Day, the immediately succeeding Business Day), the Servicer shall furnish to the Master Servicer (i) (a) monthly loan data in a mutually agreed-upon format, (b) default loan data in the format set forth in Exhibit P-1 hereto (or in such other format mutually agreed upon between the Servicer and the Master Servicer) and (c) information regarding realized losses and gains in the format set forth in Exhibit P-2 hereto (or in such other format mutually agreed upon between the Servicer and the Master Servicer), in each case relating to the period ending on the last day of the preceding calendar month, (ii) all such information required pursuant to clause (i)(a) above on a magnetic tape, electronic mail, or other similar media reasonably acceptable to the Master Servicer and (iii) all supporting documentation with respect to the information required pursuant to clause (i)(c) above.

Section 4.04

Collection of Taxes; Assessments and Similar Items; Escrow Accounts.

To the extent required by the related Mortgage Note, the Servicer shall establish and maintain one or more accounts (each, an “Escrow Account”) and deposit, promptly upon receipt, and retain therein all collections from the Mortgagors (or advances by the Servicer) for the payment of taxes, assessments, hazard insurance premiums or comparable items for the account of the Mortgagors. Nothing herein shall require the Servicer to compel a Mortgagor to establish an Escrow Account in violation of applicable law.

Withdrawals of amounts so collected from the Escrow Accounts may be made only to effect timely payment of taxes, assessments, hazard insurance premiums, condominium or PUD association dues, or comparable items, to reimburse the Servicer out of related collections for any payments made with respect to each Mortgage Loan pursuant to Section 3.01 (with respect to taxes and assessments and insurance premiums) and Section 3.05 (with respect to hazard insurance), to refund to any Mortgagors any sums as may be determined to be overages, to pay interest, if required by law or the terms of the related Mortgage or Mortgage Note, to such Mortgagors on balances in the Escrow Account, to remove amounts deposited in error or to clear and terminate the Escrow Account at the termination of this Agreement in accordance with Section 10.01 thereof.

Section 4.08

Duties of the Credit Risk Manager; Termination.

(a)

The Depositor appoints ▇▇▇▇▇▇▇ Fixed Income Services, Inc., formerly known as The Murrayhill Company, as Credit Risk Manager. For and on behalf of the Depositor, the Credit Risk Manager will provide reports and recommendations concerning the Mortgage Loans that are past due, as to which there has been commencement of foreclosure, as to which there has been forbearance in exercise of remedies which are in default, as to which a Mortgagor is the subject of bankruptcy, receivership, or an arrangement of creditors, or as to which have become REO Properties. Such reports and recommendations will be based upon information provided to the Credit Risk Manager pursuant to the Credit Risk Management Agreements and the Credit Risk Manager shall look solely to the Servicer or the Master Servicer, as applicable, for all information and data (including loss and delinquency information and data) and loan level information and data relating to the servicing of the Mortgage Loans. If the Credit Risk Manager is no longer able to perform its duties hereunder, the Credit Risk Manager may be terminated by the Depositor at the direction of Certificateholders evidencing not less than 66 2/3% of the Voting Rights. The Depositor may, at its option, cause the appointment of a successor Credit Risk Manager. Upon any termination of the Credit Risk Manager or the appointment of a successor Credit Risk Manager, the Depositor shall give written notice thereof to the Servicer, the Master Servicer, the Securities Administrator, the Trustee, each Rating Agency and the Credit Risk Manager. Notwithstanding the foregoing, the termination of the Credit Risk Manager pursuant to this Section 4.08(a) shall not become effective until the appointment of a successor Credit Risk Manager.

(b)

Within six months of the Closing Date, the Seller may, at its option, terminate the Credit Risk Manager if, in its reasonable judgment, (i) the value of the servicing rights with respect to the Mortgage Loans is adversely affected as a result of the presence of the Credit Risk Manager or (ii) the presence of the Credit Risk Manager impairs the ability of the Seller to transfer the servicing rights with respect to the Mortgage Loans as permitted by this Agreement. Upon the termination of the Credit Risk Manager, the Seller may, at its option, cause the Depositor to appoint a successor Credit Risk Manager. Notice of such termination shall be provided by the Seller to the Rating Agencies, the Trustee, the Securities Administrator, the Master Servicer, the Depositor, the Servicer and the Credit Risk Manager. Upon the appointment of a successor Credit Risk Manager, the Depositor shall provide written notice thereof to each Rating Agency, the Trustee, the Securities Administrator, the Master Servicer, the Servicer and the Credit Risk Manager.

If the Credit Risk Manager is terminated pursuant to this Section 4.08(b), the Credit Risk Manager shall only be entitled to a fee equal to 0.0050% with respect to each Mortgage Loan for the one year period following such termination. After the expiration of such one year period, the Credit Risk Manager shall not be entitled to the Credit Risk Management Fee or any portion thereof with respect to any Mortgage Loan. The excess of the Credit Risk Management Fee with respect to each Mortgage Loan over the amount payable to the Credit Risk Manager as described in this paragraph shall be paid to the Seller pursuant to Section 4.07(a)(vii).

Section 4.09

Limitation Upon Liability of the Credit Risk Manager.

Neither the Credit Risk Manager, nor any of the directors, officers, employees or agents of the Credit Risk Manager, shall be under any liability to the Master Servicer, the Securities Administrator, the Trustee, the Certificateholders or the Depositor for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, in reliance upon information provided by the Servicer under the Credit Risk Management Agreement or of errors in judgment; provided, however, that this provision shall not protect the Credit Risk Manager or any such person against liability that would otherwise be imposed by reason of willful malfeasance, bad faith or gross negligence in its performance of its duties under this Agreement or the Credit Risk Management Agreement. The Credit Risk Manager and any director, officer, employee or agent of the Credit Risk Manager 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, and may rely in good faith upon the accuracy of information furnished by the Servicer pursuant to the Credit Risk Management Agreement in the performance of its duties thereunder and hereunder.

If the Servicer shall have determined that it has made a Nonrecoverable Advance or that a proposed Advance or a lesser portion of such Advance would constitute a Nonrecoverable Advance, the Servicer shall deliver (i) to the Securities Administrator for the benefit of the Certificateholders funds constituting the remaining portion of such Advance, if applicable, and (ii) to the Depositor, each Rating Agency, the Securities Administrator and the Master Servicer an Officer’s Certificate setting forth the basis for such determination.

In lieu of making all or a portion of such Advance from its own funds, the Servicer may (i) cause to be made an appropriate entry in its records relating to the Custodial Account that any Amounts Held for Future Distribution has been used by the Servicer in discharge of its obligation to make any such Advance and (ii) transfer such funds from the Custodial Account to the Distribution Account. Any funds so applied and transferred shall be replaced by the Servicer by deposit in the Distribution Account, no later than the close of business on any future Remittance Date on which the funds on deposit in the Custodial Account shall be less than the amount required to be remitted to the Trust on such Remittance Date; provided, however that if the rating of the Servicer (including any Successor Servicer) is less than “BBB”, the Servicer shall be required to replace such funds by deposit to the Distribution Account, no later than the close of business on the Remittance Date immediately following the Due Period or Prepayment Period for which such amounts relate.

The Servicer shall be entitled to be reimbursed from the Custodial Account for all Advances of its own funds made pursuant to this Section as provided in Section 4.02. The obligation to make Advances with respect to any Mortgage Loan shall continue until such Mortgage Loan is paid in full or the related Mortgaged Property or related REO Property has been liquidated or until the purchase or repurchase thereof (or substitution therefor) from the Trust Fund pursuant to any applicable provision of this Agreement, except as otherwise provided in this Section 5.01. Notwithstanding the foregoing, the Servicer shall have no obligation to continue to make any Advances on any Mortgage Loan that is 180 days Delinquent, except as provided in Section 3.09 hereof.

Subject to and in accordance with the provisions of Article IIIA and Article VIII hereof, in the event that the Servicer fails to make such Advance, then the Master Servicer, as Successor Servicer, or in the event that the Master Servicer fails to make such Advance, the Trustee, as a Successor Master Servicer, shall be obligated to make such Advance only to the extent such Advance, if made, would not constitute a Nonrecoverable Advance, subject to the provisions of Sections 3A.12, 5.01, 8.02 and 8.04, as applicable.

(i)

(b)

The Servicer is hereby authorized to enter into a financing or other facility (any such arrangement, an “Advance Facility”), the documentation for which complies with Section 5.01(b)(v) below, under which (1) the Servicer assigns or pledges its rights under this Agreement to be reimbursed for any or all Advances and/or Servicing Advances to (i) a Person, which may be a special-purpose bankruptcy-remote entity (an “SPV”), (ii) a Person, which may simultaneously assign or pledge such rights to an SPV or (iii) a lender (a “Lender”), which, in the case of any Person or SPV of the type described in either of the preceding clauses (i) or (ii), may directly or through other assignees and/or pledgees, assign or pledge such rights to a Person, which may include a trustee acting on behalf of holders of debt instruments (any such Person or any such Lender, an “Advance Financing Person”), and/or (2) an Advance Financing Person agrees to fund all the Advances and/or Servicing Advances required to be made by the Servicer pursuant to this Agreement. No consent of the Securities Administrator, the Master Servicer, the Trustee, Certificateholders or any other party shall be required before the Servicer may enter into an Advance Facility nor shall the Securities Administrator, the Master Servicer, the Trustee or the Certificateholders be a third party beneficiary of any obligation of an Advance Financing Person to the Servicer. Notwithstanding the existence of any Advance Facility under which an Advance Financing Person agrees to fund Advances and/or Servicing Advances, (A) the Servicer (i) shall remain obligated pursuant to this Agreement to make Advances and/or Servicing Advances pursuant to and as required by this Agreement and (ii) shall not be relieved of such obligations by virtue of such Advance Facility and (B) neither the Advance Financing Person nor any Servicer’s Assignee (as hereinafter defined) shall have any right to proceed against or otherwise contact any Mortgagor for the purpose of collecting any payment that may be due with respect to any related Mortgage Loan or enforcing any covenant of such Mortgagor under the related Mortgage Loan documents.

(ii)

If the Servicer enters into an Advance Facility, the Servicer and the related Advance Financing Person shall deliver to the Master Servicer at the address set forth in Section 11.05 hereof no later than the Servicer Remittance Date immediately following the effective date of such Advance Facility a written notice (an “Advance Facility Notice”), stating (a) the identity of the Advance Financing Person and (b) the identity of the Person (the “Servicer’s Assignee”) that will, subject to Section 5.01(b)(iii) hereof, have the right to make withdrawals from the Custodial Account pursuant to Section 4.02 hereof to reimburse previously unreimbursed Advances and/or Servicing Advances (“Advance Reimbursement Amounts”). Advance Reimbursement Amounts (i) shall consist solely of amounts in respect of Advances and/or Servicing Advances for which the Servicer would be permitted to reimburse itself in accordance with Section 4.02 hereof, assuming the Servicer had made the related Advance(s) and/or Servicing Advance(s) and (ii) shall not consist of amounts payable to a successor Servicer in accordance with Section 4.02 hereof to the extent permitted under Section 5.01(b)(v) below.

(iii)

Notwithstanding the existence of an Advance Facility, the Servicer, on behalf of the Advance Financing Person and the Servicer’s Assignee, shall be entitled to receive reimbursements of Advances and/or Servicing Advances in accordance with Section 4.02 hereof, which entitlement may be terminated by the Advance Financing Person pursuant to a written notice to the Master Servicer and the Securities Administrator in the manner set forth in Section 11.05 hereof. Upon receipt of such written notice, the Servicer shall no longer be entitled to receive reimbursement for any Advance Reimbursement Amounts and the Servicer’s Assignee shall immediately have the right to receive from the Custodial Account all Advance Reimbursement Amounts. Notwithstanding the foregoing, and for the avoidance of doubt, (i) the Servicer and/or the Servicer’s Assignee shall only be entitled to reimbursement of Advance Reimbursement Amounts hereunder from withdrawals from the Custodial Account pursuant to Section 4.02 of this Agreement and shall not otherwise be entitled to make withdrawals or receive amounts that shall be deposited in the Distribution Account pursuant to Section 4.06 hereof, and (ii) none of the Securities Administrator, the Master Servicer, the Trustee or the Certificateholders shall have any right to, or otherwise be entitled to, receive any Advance Reimbursement Amounts to which the Servicer or Servicer’s Assignee, as applicable, shall be entitled pursuant to Section 4.02 hereof. An Advance Facility may be terminated by the joint written direction of the Servicer and the related Advance Financing Person. Written notice of such termination shall be delivered to the Master Servicer and the Securities Administrator in the manner set forth in Section 11.05 hereof. None of the Depositor, the Master Servicer, the Securities Administrator or the Trustee shall, as a result of the existence of any Advance Facility, have any additional duty or liability with respect to the calculation or payment of any Advance Reimbursement Amount, nor, as a result of the existence of any Advance Facility, shall the Depositor, the Master Servicer, the Securities Administrator or the Trustee have any additional responsibility to track or monitor the administration of the Advance Facility or the payment of Advance Reimbursement Amounts to Servicer’s Assignee. The Servicer shall indemnify the Depositor, the Trustee, the Securities Administrator, the Master Servicer, any Successor Servicer and the Trust Fund for any claim, loss, liability or damage resulting from any claim by the related Advancing Financing 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 Depositor, the Trustee, the Securities Administrator, the Master Servicer or any Successor Servicer, as the case may be. The Servicer shall maintain and provide to any Successor Servicer and, upon request, 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 Financing Person. The Successor Servicer shall be entitled to rely on any such information provided by the Servicer, and the Successor Servicer shall not be liable for any errors in such information.

(iv)

An Advance Financing Person who receives an assignment or pledge of rights to receive Advance Reimbursement Amounts and/or whose obligations are limited to the funding of Advances and/or Servicing Advances pursuant to an Advance Facility shall not be required to meet the criteria for qualification as the Servicer.

(v)

As between the Servicer and its Advance Financing Person, on the one hand, and a successor Servicer and its Advance Financing Person, if any, on the other hand, Advance Reimbursement Amounts on a loan-by-loan basis with respect to each Mortgage Loan as to which an Advance and/or Servicing Advance shall have been made and be outstanding shall be allocated on a “first-in, first out” basis. In the event the Servicer’s Assignee shall have received some or all of an Advance Reimbursement Amount related to Advances and/or Servicing Advances that were made by a Person other than the Servicer or its related Advance Financing Person in error, then the Servicer’s Assignee shall be required to remit any portion of such Advance Reimbursement Amount to each Person entitled to such portion of such Advance Reimbursement Amount. Without limiting the generality of the foregoing, the Servicer shall remain entitled to be reimbursed by the Advance Financing Person for all Advances and/or Servicing Advances funded by the Servicer to the extent the related Advance Reimbursement Amounts have not been assigned or pledged to such Advance Financing Person or Servicer’s Assignee.

(vi)

For purposes of any Officer’s Certificate of the Servicer delivered pursuant to Section 5.01(a), any Nonrecoverable Advance referred to therein may have been made by the Servicer. In making its determination that any Advance or Servicing Advance theretofore made has become a Nonrecoverable Advance, the Servicer shall apply the same criteria in making such determination regardless of whether such Advance or Servicing Advance shall have been made by the Servicer.

(vii)

Any amendment to this Section 5.01(b) 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 5.01(b), including amendments to add provisions relating to a successor Servicer, may be entered into by the Trustee, the Depositor, the Master Servicer, the Securities Administrator, the Seller and the Servicer without the consent of any Certificateholder, provided such amendment complies with Section 11.01 hereof. All reasonable costs and expenses (including attorneys’ fees) of each party hereto of any such amendment shall be borne solely by the Servicer. The parties hereto hereby acknowledge and agree that: (a) the Advances and/or Servicing Advances financed by and/or pledged to an Advance Financing Person under any Advance Facility are obligations owed to the Servicer payable only from the cash flows and proceeds received under this Agreement for reimbursement of Advances and/or Servicing Advances only to the extent provided herein, and the Master Servicer, the Securities Administrator, the Trustee and the Trust are not, as a result of the existence of any Advance Facility, obligated or liable to repay any Advances and/or Servicing Advances financed by the Advance Financing Person; (b) the Servicer will be responsible for remitting to the Advance Financing Person the applicable amounts collected by it as reimbursement for Advances and/or Servicing Advances funded by the Advance Financing Person, subject to the provisions of this Agreement; and (c) the Master Servicer, the Securities Administrator and the Trustee shall not have any responsibility to track or monitor the administration of the financing arrangement between the Servicer and any Advance Financing Person.

Section 5.02

Compensating Interest Payments.

In the event that there is a Prepayment Interest Shortfall arising from a voluntary Principal Prepayment in part or in full by the Mortgagor with respect to any Mortgage Loan, the Servicer shall, to the extent of the Servicing Fee for such Distribution Date, deposit into the Distribution Account, as a reduction of and to the extent of, the Servicing Fee for such Distribution Date, no later than the close of business on the Remittance Date immediately preceding such Distribution Date, an amount equal to the Prepayment Interest Shortfall; and in case of such deposit, the Servicer shall not be entitled to any recovery or reimbursement from the Depositor, the Trustee, the Master Servicer, the Securities Administrator, the Seller, the Trust Fund or the related Certificateholders. In the event that the Servicer fails to perform its duties pursuant to this Section 5.02, the Master Servicer shall deposit Compensating Interest to the Distribution Account to the extent provided in Section 3A.11 hereof.

Section 5.03

REMIC Distributions.

On each Distribution Date the Securities Administrator shall be deemed to allocate distributions to the Regular Interests in each REMIC formed hereby in accordance with the Preliminary Statement hereof.

Section 5.04

Class P Certificate Account.

The Securities Administrator shall establish and maintain with itself a separate, segregated trust account titled “Nomura Asset Acceptance Corporation, Alternative Loan Trust 2005-S4 Class P Certificate Account”. On the Closing Date, the Depositor will deposit, or cause to be deposited in the Class P Certificate Account $100.00. The amount on deposit in the Class P Certificate Account shall be held uninvested. On the Distribution Date in January 2011 (or the final Distribution Date, if earlier), the Securities Administrator shall withdraw the amount on deposit in the Class P Certificate Account and remit such amount to the Holders of the Class P Certificates, in reduction of the Certificate Principal Balance thereof.

Section 5.07

Allocation of Realized Losses.

(a)

On each Distribution Date, the Securities Administrator shall determine the total of the Applied Loss Amount, if any, for such Distribution Date, based solely on the reports delivered by the Servicer under this Agreement. The Applied Loss Amount for any Distribution Date shall be applied by reducing the Certificate Principal Balance of each Class of Subordinate Certificates entitled to principal beginning with such Class of Subordinate Certificates then outstanding with the lowest relative payment priority, in each case until the respective Certificate Principal Balance thereof is reduced to zero. Any Applied Loss Amount allocated to such Class of Subordinate Certificates shall be allocated among the Subordinate Certificates of such Class in proportion to their respective Percentage Interests.

(b)

With respect to any Class of Subordinate Certificates to which a Realized Loss or Applied Loss Amount, as applicable, has been allocated (including any such Class for which the related Certificate Principal Balance has been reduced to zero), the Certificate Principal Balance of such Class will be increased, up to the amount of related Subsequent Recoveries for such Distribution Date as follows:

Any increase to the Certificate Principal Balance of a Class of Certificates shall increase the Certificate Principal Balance of the related Certificates pro rata in accordance with each Certificate’s Percentage Interest.

(a)

On the Closing Date, the Securities Administrator shall establish and maintain in the name of the Trustee, in trust for the benefit of the Certificates, the Interest Rate Cap Account.

(b)

On or prior to the Closing Date, the Depositor shall direct the Trustee, on behalf of the Trust, to enter into the Interest Rate Cap Agreement for the benefit of the Holders of the Certificates.

(c)

The Depositor will prepare and deliver any notices required to be delivered to the Interest Rate Cap Agreement Provider under the Interest Rate Cap Account.

Upon the occurrence of an event of default under the Interest Rate Cap Agreement of which a Responsible Officer of the Securities Administrator has actual knowledge, the Securities Administrator shall immediately notify the Depositor of such occurrence and upon receipt of such notice, the Depositor shall direct the Trustee to terminate the Interest Rate Cap Agreement Provider. No such termination shall be an expense of the Trustee or the Securities Administrator.

(e)

On each Distribution Date, amounts on deposit in the Interest Rate Cap Account shall be applied by the Securities Administrator, first, to the Principal Remittance Amount, up to the amount of Realized Losses on the Mortgage Loans incurred during the related Due Period, and, second, sequentially, to the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class B-1, Class B-2, Class B-3, Class B-4 and Class B-5 Certificates, in that order, any applicable Deferred Amounts, with interest therein at the applicable Pass-Through Rate, prior to giving effect to amounts available to be paid in respect of Deferred Amounts as described in Section 5.06(d)(ii)-(xii) on such Distribution Date;

(f)

Funds in the Interest Rate Cap Account shall remain uninvested. The Interest Rate Cap Account shall be accounted for by the Securities Administrator as an outside reserve fund within the meaning of Treasury regulation 1.860G-2(h) and not an asset of any REMIC created pursuant to this Agreement. Amounts paid by the Interest Rate Cap Account shall be treated by the Securities Administrator as payments made from outside the REMICs for all Federal tax purposes. Any net investment earnings on such amounts shall be payable to the Class X-1 Certificateholder. The Class X-1 Certificateholder will be the owner of the Interest Rate Cap Account for federal tax purposes. Upon termination of the Trust Fund, any amounts remaining in the Interest Rate Cap Account shall be distributed to the Class X-1 Certificateholders.

(g)

Amounts paid under the Interest Rate Cap Agreement not used on any Distribution Date as described in Section 5.08(e) shall remain on deposit in the Interest Rate Cap Account and may be available on future Distribution Dates to make the payments described in Section 5.08(e).

(h)

On the Distribution Date immediately after the Interest Rate Cap Agreement Termination Date, any amounts on deposit in the Interest Rate Cap Account not distributable to Section 5.08(e) above shall be distributed to the Class X-1 Certificateholders.

Parties that are unable to use the above distribution options are entitled to have a paper copy mailed to them via first class mail by calling the customer service desk and indicating such. The Securities Administrator may change the way monthly statements are distributed in order to make such distributions more convenient or more accessible to the above parties.

The Securities Administrator’s responsibility for making the above information available to the Certificateholders is limited to the availability, timeliness and accuracy of the information derived from the Depositor, the Master Servicer, the Interest Rate Cap Agreement Provider and the Servicer. The Securities Administrator will make available a copy of each statement provided pursuant to this Section 5.09 to each Rating Agency.

(c)

Within a reasonable period of time after the end of each calendar year, the Securities Administrator shall cause to be furnished upon request to each Person who at any time during the calendar year was a Certificateholder, a statement containing the information set forth in clauses (a)(i) and (a)(ii) of this Section 5.09 aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder. Such obligation of the Securities Administrator shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Securities Administrator pursuant to any requirements of the Code as from time to time in effect.

Section 5.10

Basis Risk Reserve Fund.

(a)

On the Closing Date, the Securities Administrator shall establish and maintain an account in the name of the Trustee, for the benefit of the Certificateholders, called the Basis Risk Reserve Fund. 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 moneys, including without limitation, other moneys held by the Securities Administrator pursuant to this Agreement.

(b)

On the Closing Date, $1,000 will be deposited by the Depositor into the Basis Risk Reserve Fund. On each Distribution Date, the Securities Administrator shall transfer amounts from the Distribution Account to the Basis Risk Reserve Fund pursuant to Section 5.06(d)(xiii). Amounts on deposit in the Basis Risk Reserve Fund shall be withdrawn by the Securities Administrator on any Distribution Date to fund the amounts required to be distributed to holders of the LIBOR Certificates and Class B-4 and B-5 Certificates pursuant to Section 5.06(d)(xiii).

(c)

Funds in the Basis Risk Reserve Fund may be invested in Permitted Investments by the Securities Administrator at the written direction of the holders of the Class X-1 Certificates maturing on the Business Day prior to the next succeeding Distribution Date (and if no such direction is received, such funds shall not be invested). Any net investment earnings on such amounts shall be payable to the holders of the Class X-1 Certificates pursuant to Section 5.10(d). The Basis Risk Reserve Fund shall be accounted for by the Securities Administrator as an outside reserve fund within the meaning of Treasury regulation 1.860G-2(h) and not an asset of any REMIC created pursuant to this Agreement. The Class X-1 Certificates shall evidence ownership of the Basis Risk Reserve Fund for federal tax purposes and the Holders thereof shall direct the Securities Administrator in writing as to the investment of amounts therein. The amounts transferred by the Master REMIC to the Basis Risk Reserve Fund shall be treated by the Securities Administrator as distributions to the Class X-1 Certificateholder in respect of the Class X-1 Interest for all Federal tax purposes. In the absence of such written direction, all funds in the Basis Risk Reserve Fund shall remain uninvested. The Securities Administrator shall have no liability for losses on investments in Eligible Investments made pursuant to this Section 5.10(c). Upon termination of the Trust Fund, any amounts remaining in the Basis Risk Reserve Fund shall be distributed to the Holders of the Class X-1 Certificates.

(d)

On the Distribution Date immediately after the Distribution Date on which the aggregate Certificate Principal Balance of the LIBOR Certificates and the Class B-4 and Class B-5 Certificates equals zero, any amounts on deposit in the Basis Risk Reserve Fund not payable on the LIBOR Certificates and Class B-4 and Class B-5 Certificates shall be distributed to the Holders of the Class X-1 Certificates.

(e)

The Securities Administrator shall treat the beneficial owners of Certificates (other than the Class A-IO, Class P, Class X-1, Class X-2 and Class R Certificates) as having entered into a notional principal contract with respect to the beneficial owners of the Class X-1 Certificates. Pursuant to such notional principal contract, the beneficial owner of the Class X-1 Certificates shall be treated as having agreed to pay Basis Risk Shortfalls to the holders of the beneficial owners of Certificates (other than the Class A-IO, Class P, Class X-1, Class X-2 and Class R 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), and each Certificate (other than the Class A-IO, Class P, Class X-1, Class X-2 and Class R Certificates) shall be treated as representing not only ownership of regular interests in the Master REMIC, but also ownership of an interest in a notional principal contract. For tax purposes, the notional principal contract shall be deemed to have a value of $5,000 as of the Closing Date.

(f)

Notwithstanding the priority and sources of payments set forth in Article V hereof or otherwise, the Securities Administrator shall account for all distributions on the Certificates in respect of Basis Risk Shortfalls as set forth in this Section 5.10. In no event shall any payments of Basis Risk Shortfalls provided for in this Section 5.10 be treated as payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1).

ARTICLE VI

THE CERTIFICATES

Section 6.01

The Certificates.

The Certificates shall be substantially in the forms attached hereto as Exhibits A-1 through A-6. The Class A-1, Class A-2, Class A-3, Class A-IO, Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class B-1, Class B-2 and Class B-3 Certificates shall be issuable in registered form, and the Class B-4, Class B-5, Class X-1, Class X-2, Class P and Class R Certificates shall be issuable in fully certificated form in the minimum dollar denominations, integral dollar multiples in excess thereof (except that one Certificate of each Class may be issued in a different amount which must be in excess of the applicable minimum dollar denomination) and aggregate dollar denominations as set forth in the Preliminary Statement.

The Certificates shall be executed by manual or facsimile signature on behalf of the Securities Administrator by an authorized officer upon the written order of the Depositor. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Securities Administrator shall bind the Trust Fund, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such authentication and delivery. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate the countersignature of the Securities Administrator by manual signature, and such countersignature upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly countersigned and delivered hereunder. All Certificates shall be dated the date of their countersignature. On the Closing Date, the Securities Administrator shall authenticate the Certificates to be issued at the written direction of the Depositor, or any affiliate thereof.

The Depositor shall provide, or cause to be provided, to the Securities Administrator on a continuous basis, an adequate inventory of Certificates to facilitate transfers.

Section 6.02

Certificate Register; Registration of Transfer and Exchange of Certificates.

(a)

The Securities Administrator shall maintain, or cause to be maintained in accordance with the provisions of Section 6.09, a Certificate Register for the Trust Fund in which, subject to the provisions of subsections (b) and (c) below and to such reasonable regulations as it may prescribe, the Securities Administrator shall provide for the registration of Certificates and of Transfers and exchanges of Certificates as herein provided. Upon surrender for registration of Transfer of any Certificate, the Securities Administrator shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same Class and of like aggregate Percentage Interest.

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest upon surrender of the Certificates to be exchanged at the office or agency of the Trustee. Whenever any Certificates are so surrendered for exchange, the Securities Administrator shall execute, authenticate, and deliver the Certificates that the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of Transfer or exchange shall be accompanied by a written instrument of Transfer in form satisfactory to the Securities Administrator duly executed by the holder thereof or his attorney duly authorized in writing.

No service charge to the Certificateholders shall be made for any registration of Transfer or exchange of Certificates, but payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any Transfer or exchange of Certificates may be required.

All Certificates surrendered for registration of Transfer or exchange shall be canceled and subsequently destroyed by the Securities Administrator in accordance with the Securities Administrator’s customary procedures.

(b)

No Transfer of any Private Certificate shall be made unless such Transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under the Securities Act and such state securities laws. In the event that a Transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such Transfer and such Certificateholder’s prospective transferee shall each certify to the Securities Administrator in writing the facts surrounding the Transfer in substantially the forms set forth in Exhibit E (the “Transferor Certificate”) and (x) deliver a letter in substantially the form of either Exhibit F (the “Investment Letter”), if the entire Class is being sold to one investor or the Depositor otherwise consents, or Exhibit G (the “Rule 144A Letter”) or (y) there shall be delivered to the Securities Administrator an Opinion of Counsel, at the expense of the transferor, that such Transfer may be made pursuant to an exemption from the Securities Act, which Opinion of Counsel shall not be an expense of the Depositor, the Seller, the Securities Administrator, the Trustee or the Trust Fund. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for Transfer of any such Certificate without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A. The Securities Administrator shall cooperate with the Depositor in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Depositor shall reasonably request to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such Transfer shall, and does hereby agree to, indemnify the Securities Administrator, the Trustee, the Depositor and the Seller against any liability that may result if the Transfer is not so exempt or is not made in accordance with such federal and state laws.

With respect to the transfer of a Book-Entry Certificate that is a Private Certificate, the representation that the proposed transferee of such Certificate is a QIB shall be deemed to have been made to the Securities Administrator and the Trustee by the transferee’s acceptance of a Book-Entry Certificate (or the acceptance by a Certificate Owner of the beneficial interest in any such Class of Book-Entry Certificates).

No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate shall be made unless (x) the Securities Administrator shall have received from the transferee of such Certificate in accordance with Exhibit D, Exhibit F or Exhibit G, as applicable, in form and substance satisfactory to the Securities Administrator, either (i) a representation letter to the effect that such transferee is not an employee benefit plan or arrangement subject to Section 406 of ERISA or Section 4975 of the Code, or a person acquiring the Certificate for, on or behalf of or with the assets of, any such plan or arrangement (“Benefit Plan Investor”) or (ii) an Opinion of Counsel to the effect that the purchase or holding of such ERISA-Restricted Certificate will not result in prohibited transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Depositor, the Seller, the Securities Administrator, the Master Servicer, the Trustee or the Servicer to any obligation in addition to those undertaken in this Agreement, or (y) if the Certificate has been subject of an ERISA-Qualifying Underwriting, a representation letter that the purchaser is an insurance company which is purchasing such Certificate with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60. Neither the representation letter nor the Opinion of Counsel shall be an expense of any of the above parties or the Trust Fund. Such representations shall be deemed to have been made to the Securities Administrator and the Trustee by the transferee’s acceptance of an ERISA-Restricted Certificate by any beneficial owner who purchases an interest in such Certificate in book-entry form. In the event that a representation is violated, or any attempt to transfer an ERISA-Restricted Certificate to a Benefit Plan Investor is attempted without the delivery to the Securities Administrator of the Opinion of Counsel described above, the attempted transfer or acquisition of such Certificate shall be void and of no effect.

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

None of the Securities Administrator, the Trustee or the Depositor shall have any liability to any Person for any registration of transfer of any Certificate that is in fact not permitted by this Section 6.02(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Securities Administrator in accordance with the foregoing requirements. In addition, none of the Securities Administrator, the Trustee or the Depositor shall be required to monitor, determine or inquire as to compliance with the transfer restrictions with respect to any Book-Entry Certificate, and none of the Securities Administrator, the Trustee or the Depositor shall have any liability for transfers of Book-Entry Certificates or any interests therein made in violation of the restrictions on transfer described in the Private Offering Circular or this Agreement.

(c)

Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Securities Administrator of any change or impending change in its status as a Permitted Transferee.

(ii)

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

(iii)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee.

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 6.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 6.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. Neither the Securities Administrator nor the Trustee shall be under any liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 6.02(b) and this Section 6.02(c) 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 after receipt of the related Transfer Affidavit. The Securities Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Securities Administrator shall be paid and delivered by the Securities Administrator to the last preceding Permitted Transferee of such Certificate.

The restrictions on Transfers of a Residual Certificate set forth in this Section 6.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Securities Administrator of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Securities Administrator, the Trustee or the Seller to the effect that the elimination of such restrictions will not cause any REMIC to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement that, based on an Opinion of Counsel furnished to the Securities Administrator, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is not a Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate that is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.

(d)

The preparation and delivery of all certificates and opinions referred to above in this Section 6.02 shall not be an expense of the Trust Fund, the Trustee, the Depositor, the Securities Administrator or the Seller.

Section 6.03

Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Securities Administrator, or the Securities Administrator e receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and of the ownership thereof and (b) there is delivered to the Securities Administrator and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Securities Administrator that such Certificate has been acquired by a bona fide purchaser, the Securities Administrator shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like Class, tenor and Percentage Interest. In connection with the issuance of any new Certificate under this Section 6.03, the Securities Administrator may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Securities Administrator) connected therewith. Any replacement Certificate issued pursuant to this Section 6.03 shall constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. All Certificates surrendered to the Securities Administrator under the terms of this Section 6.03 shall be canceled and destroyed by the Securities Administrator in accordance with its standard procedures without liability on its part.

Section 6.04

Persons Deemed Owners.

The Securities Administrator and the Trustee and any agent of the Securities Administrator and the Trustee may treat the person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and neither the Securities Administrator nor any agent of the Securities Administrator and the Trustee shall be affected by any notice to the contrary.

Section 6.05

Access to List of Certificateholders’ Names and Addresses.

If three or more Certificateholders (a) request such information in writing from the Securities Administrator, (b) state that such Certificateholders desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates, and (c) provide a copy of the communication that such Certificateholders propose to transmit or if the Depositor shall request such information in writing from the Securities Administrator, then the Securities Administrator shall, within ten Business Days after the receipt of such request, provide the Depositor or such Certificateholders at such recipients’ expense the most recent list of the Certificateholders of the Trust Fund held by the Securities Administrator, if any. The Depositor and every Certificateholder, by receiving and holding a Certificate, agree that the Securities Administrator shall not be held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 6.06

Book-Entry Certificates.

The Certificates, other than the Private Certificates upon original issuance, shall be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates, to be delivered to the Depository by or on behalf of the Depositor. Such Certificates shall initially be registered on the Certificate Register in the name of the Depository or its nominee, and no Certificate Owner of such Certificates will receive a definitive certificate representing such Certificate Owner’s interest in such Certificates, except as provided in Section 6.08. Unless and until definitive, fully registered Certificates (“Definitive Certificates”) have been issued to the Certificate Owners of such Certificates pursuant to Section 6.08:

(a)

the provisions of this Section shall be in full force and effect;

(b)

the Depositor, the Trustee and the Securities Administrator may deal with the Depository and the Depository Participants for all purposes (including the making of distributions) as the authorized representative of the respective Certificate Owners of such Certificates;

(c)

registration of the Book-Entry Certificates may not be transferred by the Trustee or the Securities Administrator except to another Depository;

(d)

the rights of the respective Certificate Owners of such Certificates shall be exercised only through the Depository and the Depository Participants and shall be limited to those established by law and agreements between the Owners of such Certificates and the Depository and/or the Depository Participants. Pursuant to the Depository Agreement, unless and until Definitive Certificates are issued pursuant to Section 6.08, the Depository will make book-entry transfers among the Depository Participants and receive and transmit distributions of principal and interest on the related Certificates to such Depository Participants;

(e)

the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants;

(f)

the Securities Administrator and the Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants; and

(g)

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

As of the Closing Date, the Private Certificates shall be Definitive Certificates. For purposes of any provision of this Agreement requiring or permitting actions with the consent of, or at the direction of, Certificateholders evidencing a specified percentage of the aggregate unpaid principal amount of any Class of Certificates, such direction or consent may be given by Certificate Owners (acting through the Depository and the Depository Participants) owning Book-Entry Certificates evidencing the requisite percentage of principal amount of such Class of Certificates.

Section 6.07

Notices to Depository.

Whenever any notice or other communication is required to be given to Certificateholders of a Class with respect to which Book-Entry Certificates have been issued, unless and until Definitive Certificates shall have been issued to the related Certificate Owners, the Securities Administrator shall give all such notices and communications to the Depository.

Section 6.08

Definitive Certificates.

If, after Book-Entry Certificates have been issued with respect to any Certificates, (a) the Depositor or the Depository advises the Securities Administrator that the Depository is no longer willing or able to discharge properly its responsibilities under the Depository Agreement with respect to such Certificates and the Securities Administrator or the Depositor is unable to locate a qualified successor, (b) the Depositor, with the consent of the related Depository Participants, advises the Securities Administrator that it elects to terminate the book-entry system with respect to such Certificates through the Depository or (c) after the occurrence and continuation of a Servicer Default, Certificate Owners of such Book-Entry Certificates having not less than 51% of the Voting Rights evidenced by any Class of Book-Entry Certificates advise the Securities Administrator and the Depository in writing through the Depository Participants that the continuation of a book-entry system with respect to Certificates of such Class through the Depository (or its successor) is no longer in the best interests of the Certificate Owners of such Class and the related Depository Participants consent to such a termination, then the Securities Administrator at the expense of the Trust Fund shall notify all Certificate Owners of such Certificates, through the Depository, of the occurrence of any such event and of the availability of Definitive Certificates to applicable Certificate Owners requesting the same. The Depositor shall provide the Securities Administrator with an adequate inventory of certificates to facilitate the issuance and transfer of Definitive Certificates. Upon surrender to the Securities Administrator of any such Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Securities Administrator shall countersign and deliver such Definitive Certificates. Neither the Depositor nor the Securities Administrator shall be liable for any delay in delivery of such instructions and each may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of such Definitive Certificates, all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Securities Administrator, to the extent applicable with respect to such Definitive Certificates and the Securities Administrator shall recognize the Holders of such Definitive Certificates as Certificateholders hereunder. As of the Closing Date, the Private Certificates shall be Definitive Certificates.

Section 6.09

Maintenance of Office or Agency.

The Securities Administrator will maintain or cause to be maintained at its expense an office or offices or agency or agencies, which shall be initially located at Sixth Street and Marquette Avenue, Minneapolis, Minnesota 55479, Attention: Corporate Trust Services (NAAC 2005-S4), where Certificates may be surrendered for registration of transfer or exchange.

(a)

The Seller may, at its option, terminate the servicing responsibilities of GMAC Mortgage Corporation as Servicer hereunder with respect to the Mortgage Loans without cause.

No appointment shall be effective unless (i) such successor to GMAC Mortgage Corporation meets the eligibility criteria contained in Section 8.02, (ii) the Master Servicer shall have consented to such appointment, (iii) the Rating Agencies have confirmed in writing that such appointment will not result in a downgrade, qualification or withdrawal of the then current ratings assigned to the Certificates, (iv) such successor has agreed to assume the obligations of GMAC Mortgage Corporation hereunder to the extent of the Mortgage Loans and (v) all amounts reimbursable to GMAC Mortgage Corporation pursuant to the terms of this Agreement shall have been paid to GMAC Mortgage Corporation by the successor appointed pursuant to the terms of this Section 7.06 or by the Seller including without limitation, all unreimbursed Advances and Servicing Advances made by GMAC Mortgage Corporation and all out-of-pocket expenses of GMAC Mortgage Corporation incurred in connection with the transfer of servicing to such successor. The Seller shall provide a copy of the written confirmation of the Rating Agencies and the agreement executed by such successor to the Trustee, the Master Servicer and the Securities Administrator.

(b)

In addition, the Seller may, at its option, appoint a special servicer with respect to certain of the Mortgage Loans. The Seller and GMAC Mortgage Corporation shall negotiate in good faith with any proposed special servicer with respect to the duties and obligations of such special servicer with respect to any such Mortgage Loan.

Any such determination pursuant to the preceding sentence permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel to such effect obtained at the expense of the Master Servicer and delivered to the Trustee and the Rating Agencies. No resignation of the Master Servicer shall become effective until the Trustee or a successor Master Servicer meeting the criteria specified in Section 7.08 shall have assumed the Master Servicer’s responsibilities, duties, liabilities (other than those liabilities arising prior to the appointment of such successor) and obligations under this Agreement.

Section 7.08

Assignment of Master Servicing.

The Master Servicer may sell and assign its rights and delegate its duties and obligations in its entirety as Master Servicer under this Agreement; provided, however, that: (i) the purchaser or transferee accepting such assignment and delegation and assuming the obligations of the Master Servicer hereunder (a) shall have a net worth of not less than $15,000,000 (unless otherwise approved by each Rating Agency pursuant to clause (ii) below); (b) shall be reasonably satisfactory to the Trustee (as evidenced in a writing signed by the Trustee); and (c) shall execute and deliver to the Trustee an agreement, in form and substance reasonably satisfactory to the Trustee, which contains an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed or observed by it as master servicer under this Agreement from and after the effective date of such agreement; (ii) each Rating Agency shall be given prior written notice of the identity of the proposed successor to the Master Servicer and each Rating Agency’s rating of the Certificates in effect immediately prior to such assignment, sale and delegation will not be downgraded, qualified or withdrawn as a result of such assignment, sale and delegation, as evidenced by a letter to such effect delivered to the Master Servicer and the Trustee; and (iii) the Master Servicer assigning the master servicing shall deliver to the Trustee an officer’s certificate and an Opinion of Counsel, which counsel shall be independent of the Master Servicer, each stating that all conditions precedent to such action under this Agreement have been completed and such action is permitted by and complies with the terms of this Agreement. No such assignment or delegation shall affect any liability of the Master Servicer arising out of acts or omissions prior to the effective date thereof.

Section 7.09

Rights of the Depositor in Respect of the Servicer and the Master Servicer.

Each of the Master Servicer and the Servicer shall afford (and any Subservicing Agreement shall provide that each subservicer shall afford) the Depositor and the Trustee, upon reasonable notice, during normal business hours, access to all records maintained by the Master Servicer or the Servicer (and any such subservicer) in respect of the Servicer’s rights and obligations hereunder and access to officers of the Master Servicer or the Servicer (and those of any such subservicer) responsible for such obligations, and the Master Servicer shall have access to all such records maintained by the Servicer and any subservicers. Upon request, each of the Master Servicer and the Servicer shall furnish to the Depositor and the Trustee its (and any such Sub-Servicer’s) most recent financial statements and such other information relating to the Master Servicer’s or the Servicer’s capacity to perform its obligations under this Agreement as it possesses (and that any such subservicer possesses). To the extent such information is not otherwise available to the public, the Depositor and the Trustee shall not disseminate any information obtained pursuant to the preceding two sentences without the Master Servicer’s or the Servicer’s written consent, except as required pursuant to this Agreement or to the extent that it is appropriate to do so (i) to its legal counsel, auditors, taxing authorities or other governmental agencies and the Certificateholders, (ii) pursuant to any law, rule, regulation, order, judgment, writ, injunction or decree of any court or governmental authority having jurisdiction over the Depositor and the Trustee or the Trust Fund, and in any case, the Depositor or the Trustee, (iii) disclosure of any and all information that is or becomes publicly known, or information obtained by the Trustee from sources other than the Depositor, the Servicer or the Master Servicer, (iv) disclosure as required pursuant to this Agreement or (v) disclosure of any and all information (A) in any preliminary or final offering circular, registration statement or contract or other document pertaining to the transactions contemplated by the Agreement approved in advance by the Depositor, the Servicer or the Master Servicer or (B) to any affiliate, independent or internal auditor, agent, employee or attorney of the Trustee having a need to know the same, provided that the Trustee advises such recipient of the confidential nature of the information being disclosed, shall use its best efforts to assure the confidentiality of any such disseminated non-public information. Nothing in this Section 7.09 shall limit the obligation of the Servicer to comply with any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Servicer to provide access as provided in this Section 7.09 as a result of such obligation shall not constitute a breach of this Section. Nothing in this Section 7.09 shall require the Servicer to collect, create, collate or otherwise generate any information that it does not generate in its usual course of business. The Servicer shall not be required to make copies of or ship documents to any party unless provisions have been made for the reimbursement of the costs thereof. The Depositor may, but is not obligated to, enforce the obligations of the Master Servicer and the Servicer under this Agreement and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of the Master Servicer or the Servicer under this Agreement or exercise the rights of the Master Servicer or the Servicer under this Agreement; provided that neither the Master Servicer nor the Servicer shall be relieved of any of its obligations under this Agreement by virtue of such performance by the Depositor or its designee. The Depositor shall not have any responsibility or liability for any action or failure to act by the Master Servicer or the Servicer and is not obligated to supervise the performance of the Master Servicer or the Servicer under this Agreement or otherwise.

In case one or more of the following events of default by the Servicer (each, a “Servicer Default”) shall occur and be continuing, that is to say:

(i)

any failure to remit to the Securities Administrator any payment required to be made under the terms of this Agreement (including, but not limited to Advances) which continues unremedied for a period of two Business Days; or

(ii)

failure duly to observe or perform in any material respect any other of the covenants or agreements set forth in this Agreement (other than those described in clauses (viii) and (ix) below), the breach of which has a material adverse effect on the Certificateholders and which continue unremedied for a period of thirty days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Master Servicer, the Securities Administrator or the Trustee; or

(iii)

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, bankruptcy, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of sixty days; or

(iv)

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

(v)

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 or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

(vi)

the Servicer attempts to assign its right to servicing compensation hereunder (other than any payment by the Servicer of any portion of the Servicing Fee to the Seller as provided in a separate side letter between the Seller and the Servicer) 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 or any portion thereof except, in each case as otherwise permitted herein; or

(vii)

the Servicer ceases to be qualified to transact business in any jurisdiction where it is currently so qualified, but only to the extent such non-qualification materially and adversely affects the Servicer’s ability to perform its obligations hereunder; or

(viii)

any failure by the Servicer to duly perform, within the required time period, its obligation to provide the annual compliance statements and the accountant’s report described in Sections 3.13 and 3.14 hereof, which failure continues unremedied for a period of ten (10) days after the date on which written notice of such failure, requiring the same to be remedied, has been given to the Servicer by the Master Servicer; or

(ix)

any failure by the Servicer to provide, within the required time period set forth in Section 4.03 hereof, any required reports or data pertaining to the Mortgage Loans, which failure continues unremedied for a period of thirty (30) days after the date on which written notice of such failure, requiring the same to be remedied, has been given to the Servicer by the Master Servicer;

then, and in each and every such case, so long as a Servicer Default shall not have been remedied, the Master Servicer, by notice in writing to the Servicer shall with respect to a payment default by the Servicer pursuant to Section 8.01(i) and, upon the occurrence and continuance of any other Servicer Default, may, and, at the written direction of Certificateholders evidencing not less than 25% of the Voting Rights shall, in addition to whatever rights the Master Servicer or the Trustee on behalf of the Certificateholders may have under Section 7.03 and at law or equity to damages, including injunctive relief and specific performance, terminate all the rights and obligations of the Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Servicer for the same. Upon the 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 the Master Servicer. Upon written request from the Master Servicer, the Servicer shall prepare, execute and deliver, any and all documents and other instruments, place in the Trustee’s possession, or the applicable Custodian’s possession on its behalf, all Mortgage Files relating to the related Mortgage Loans, and 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, at the Servicer’s sole expense. The defaulting Servicer shall cooperate with the Master Servicer in effecting the termination of its 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 defaulting Servicer to the Custodial Account or Escrow Accounts or thereafter received with respect to the Mortgage Loans or any related REO Property (provided, however, that the defaulting Servicer shall continue to be entitled to receive all amounts accrued or owing to it under this Agreement on or prior to the date of such termination, whether in respect of Advances, Servicing Advances, accrued and unpaid Servicing Fees or otherwise, and shall continue to be entitled to the benefits of Section 7.04, notwithstanding any such termination, with respect to events occurring prior to such termination). The Master Servicer shall not have knowledge of a Servicer Default unless a Master Servicing Officer has actual knowledge or unless written notice of any Servicer Default is received by the Master Servicer and such notice references the Certificates, the Trust Fund or this Agreement.

Section 8.02

Master Servicer to Act; Appointment of Successor.

Upon the Servicer’s receipt of a notice of termination pursuant to Section 8.01, the Master Servicer shall automatically become the successor to the Servicer with respect to the transactions set forth or provided for herein and after a transition period (not to exceed 90 days), shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Servicer by the terms and provisions hereof and applicable law including the obligation to make Advances pursuant to Article V hereof except as otherwise provided herein; provided, however, that the Master Servicer’s obligation to make Advances in its capacity as Successor Servicer shall not be subject to such 90 day transition period and the Master Servicer in such capacity will make any Advance required to be made by the predecessor Servicer on the Distribution Date on which the predecessor Servicer was required to make such Advance. Effective on the date of such notice of termination, as compensation therefor, the Master Servicer shall be entitled to all fees, costs and expenses relating to the Mortgage Loans that the terminated Servicer would have been entitled to if it had continued to act hereunder, provided, however, that the Master Servicer shall not be (i) liable for any acts or omissions of the terminated Servicer, (ii) obligated to make Advances if it is prohibited from doing so under applicable law or determines that such Advance, if made, would constitute a Nonrecoverable Advance, (iii) responsible for expenses of the terminated Servicer pursuant to Section 2.03 or (iv) obligated to deposit losses on any Permitted Investment directed by the terminated Servicer. Notwithstanding the foregoing, the Master Servicer may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to Article V or if it is otherwise unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency as the successor to the Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer hereunder. Any Successor Servicer shall (i) be an institution that is a ▇▇▇▇▇▇ ▇▇▇ and Freddie Mac approved seller/servicer in good standing, that has a net worth of at least $15,000,000 and (ii) be willing to act as Successor Servicer of any Mortgage Loans under this Agreement and shall have executed and delivered to the Depositor, the Master Servicer and the Trustee an agreement accepting such delegation and assignment, that contains an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the terminated Servicer (other than any liabilities of the terminated Servicer hereof incurred prior to termination of the Servicer under Section 8.01), with like effect as if originally named as a party to this Agreement, provided that each Rating Agency shall have acknowledged in writing that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced as a result of such assignment and delegation. If the Master Servicer assumes the duties and responsibilities of the Servicer in accordance with this Section 8.02, the Master Servicer shall not resign as Servicer until a Successor Servicer has been appointed and has accepted such appointment. Pending appointment of a successor to the terminated Servicer hereunder, the Master Servicer, unless the Master Servicer is prohibited by law from so acting, shall, subject to Section 4.04 hereof, act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Master Servicer may make such arrangements for the compensation of such successor out of payments on Mortgage Loans or otherwise as it and such successor shall agree; provided that no such compensation shall be in excess of that permitted the terminated Servicer hereunder. The Master Servicer and such successor shall take such action, consistent with this Agreement as shall be necessary to effectuate any such succession. Neither the Master Servicer nor any other Successor 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 or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

The costs and expenses of the Master Servicer in connection with the termination of the Servicer, appointment of a Successor Servicer and, if applicable, any transfer of servicing, including, without limitation, all costs and 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 or such other Successor Servicer to service the Mortgage Loans properly and effectively, to the extent not paid by the terminated Servicer as may be required herein, shall be payable to the Master Servicer from the Distribution Account pursuant to Section 4.07. Any successor to the terminated Servicer as Successor Servicer under this Agreement shall give notice to the applicable Mortgagors of such change of servicer and shall, during the term of its service as Successor Servicer maintain in force the policy or policies that the terminated Servicer is required to maintain pursuant to Section 3.05.

Section 8.03

Master Servicer Default.

In case one or more of the following events of default by the Master Servicer (each, a “Master Servicer Default”) shall occur and be continuing, that is to say:

(i)

any failure by the Master Servicer to furnish the Securities Administrator the Mortgage Loan data sufficient to prepare the reports described in Section 5.09 which continues unremedied for a period of one Business Day after the date upon which written notice of such failure shall have been given to such Master Servicer by the Trustee or the Securities Administrator or to such Master Servicer, the Securities Administrator and the Trustee by any Holder with Certificates evidencing Voting Interests of at least 25% (provided, however, that any such failure shall not be a Master ▇▇▇▇▇▇ Default if the Master Servicer did not timely receive such information from the Servicer); or

(ii)

any failure on the part of the Master Servicer duly to observe or perform in any material respect any other of the covenants or agreements (other than those referred to in clauses (viii) and (ix) below) on the part of the Master Servicer contained in this Agreement which continues unremedied for a period of thirty (30) days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Trustee or the Securities Administrator, or to the Master Servicer, the Securities Administrator and the Trustee by any Holder with Certificates evidencing Voting Interests of at least 25%; or

(iii)

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 sixty (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

(iv)

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

(v)

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

(vi)

the Master Servicer shall be dissolved, or shall dispose of all or substantially all of its assets, or consolidate with or merge into another entity or shall permit another entity to consolidate or merge into it, such that the resulting entity does not meet the criteria for a Successor Master Servicer as specified in Section 8.04 hereof; or

(vii)

if a representation or warranty set forth in Section 2.03(d) hereof shall prove to be incorrect as of the time made in any respect that materially and adversely affects the interests of the Certificateholders, and the circumstance or condition in respect of which such representation or warranty was incorrect shall not have been eliminated or cured within 30 days after the date on which written notice of such incorrect representation or warranty shall have been given to the Master Servicer by the Trustee or the Securities Administrator, or to the Master Servicer, the Securities Administrator and the Trustee by any Holder with Certificates evidencing Voting Interests of at least 25%; or

(viii)

a sale or pledge of any of the rights of the Master Servicer hereunder or an assignment of this Agreement by the Master Servicer or a delegation of the rights or duties of the Master Servicer hereunder shall have occurred in any manner not otherwise permitted hereunder and without the prior written consent of the Trustee and any Holder with Certificates evidencing Voting Interests of at least 50%; or

(ix)

after receipt of notice from the Trustee, any failure of the Master Servicer to make any Advances when such Advances are due, as required to be made hereunder;

then, and in each and every such case, so long as a Master Servicer Default shall not have been remedied, the Trustee, by notice in writing to the Master Servicer shall with respect to a payment default by the Master Servicer pursuant to Section 8.03(ii) and, upon the occurrence and continuance of any other Master Servicer Default, may, and, at the written direction of Certificateholders evidencing not less than 25% of the Voting Rights shall, in addition to whatever rights the Trustee on behalf of the Certificateholders may have under this Agreement and at law or equity to damages, including injunctive relief and specific performance, terminate all the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Master Servicer for the same. Upon the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer under this Agreement whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee. Upon written request from the Trustee, the Master Servicer shall prepare, execute and deliver, any and all documents and other instruments, place in the Trustee’s possession all Mortgage Files relating to the related Mortgage Loans, and 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, at the Master Servicer’s sole expense. The defaulting Master Servicer shall cooperate with the Trustee in effecting the termination of its 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 defaulting Master Servicer to the Custodial Account or Escrow Accounts or thereafter received with respect to the Mortgage Loans or any related REO Property (provided, however, that the defaulting Master Servicer shall continue to be entitled to receive all amounts accrued or owing to it under this Agreement on or prior to the date of such termination, whether in respect of Advances, accrued and unpaid Master Servicing Fees or otherwise, and shall continue to be entitled to the benefits of Section 7.04, notwithstanding any such termination, with respect to events occurring prior to such termination). The Trustee shall not have knowledge of a Master Servicer Default unless a Responsible Officer of the Trustee has actual knowledge or unless written notice of any Master Servicer Default is received by the Trustee at its Corporate Trust Office and such notice references the Certificates, the Trust Fund or this Agreement.

Section 8.04

Trustee to Act; Appointment of Successor.

Upon the Master Servicer’s receipt of a notice of termination pursuant to Section 8.03, the Trustee shall automatically become the successor to the Master Servicer with respect to the transactions set forth or provided for herein and after a transition period (not to exceed 90 days), shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof and applicable law including the obligation to make Advances pursuant to Article IIIA and Article V hereof except as otherwise provided herein; provided, however, that the Trustee’s obligation to make Advances in its capacity as Successor Master Servicer shall not be subject to such 90 day transition period and the Trustee in such capacity will make any Advance required to be made by the predecessor Master Servicer on the Distribution Date on which the predecessor Master Servicer was required to make such Advance. Effective on the date of such notice of termination, as compensation therefor, the Trustee shall be entitled to all fees, costs and expenses relating to the Mortgage Loans that the terminated Master Servicer would have been entitled to if it had continued to act hereunder, provided, however, that the Trustee shall not be (i) liable for any acts or omissions of the terminated Master Servicer, (ii) obligated to make Advances if it is prohibited from doing so under applicable law or determines that such Advance, if made, would constitute a Nonrecoverable Advance, (iii) responsible for expenses of the terminated Master Servicer pursuant to Section 2.03 or (iv) obligated to deposit losses on any Permitted Investment directed by the terminated Master Servicer. Notwithstanding the foregoing, the Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to Article V or if it is otherwise unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder. Any Successor Master Servicer shall (i) be an institution that is a ▇▇▇▇▇▇ ▇▇▇ and Freddie Mac approved seller/servicer in good standing, that has a net worth of at least $15,000,000 and (ii) be willing to act as Successor Master Servicer of any Mortgage Loans under this Agreement and shall have executed and delivered to the Depositor and the Trustee an agreement accepting such delegation and assignment, that contains an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the terminated Master Servicer (other than any liabilities of the terminated Master Servicer hereof incurred prior to termination of the Master Servicer under Section 8.03), with like effect as if originally named as a party to this Agreement, provided that each Rating Agency shall have acknowledged in writing that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced as a result of such assignment and delegation. If the Trustee assumes the duties and responsibilities of the Master Servicer in accordance with this Section 8.04, the Trustee shall not resign as Master Servicer until a Successor Master Servicer has been appointed and has accepted such appointment. Pending appointment of a successor to the terminated Master Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so acting, shall, subject to Section 4.04 hereof, act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans or otherwise as it and such successor shall agree; provided that no such compensation shall be in excess of that permitted the terminated Master Servicer hereunder. The Trustee and such successor shall take such action, consistent with this Agreement as shall be necessary to effectuate any such succession. 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 or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the Master Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

The costs and expenses of the Trustee in connection with the termination of the Master Servicer, appointment of a Successor Master Servicer and, if applicable, any transfer of master servicing, including, without limitation, all costs and 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 Trustee to correct any errors or insufficiencies in the servicing data or otherwise to enable the Trustee or the Successor Master Servicer to master service the Mortgage Loans properly and effectively, to the extent not paid by the terminated Master Servicer as may be required herein, shall be payable to the Trustee from the Distribution Account pursuant to Section 4.07. Any successor to the terminated Master Servicer as Successor Master Servicer under this Agreement shall give notice to the applicable Mortgagors of such change of master servicer and shall, during the term of its service as Successor Master Servicer maintain in force the policy or policies that the terminated Master Servicer is required to maintain pursuant to Article IIIA.

Section 8.05

Notification to Certificateholders.

(a)

Upon any termination of or appointment of a successor to the Servicer or the Master Servicer, the Master Servicer and the Trustee, respectively, shall give prompt written notice thereof to Certificateholders and to each Rating Agency.

(b)

Within 60 days after the occurrence of any Servicer Default or Master Servicer Default, the Master Servicer or the Trustee, respectively, shall transmit by mail to all Certificateholders notice of each Servicer Default or Master Servicer Default hereunder known to the Master Servicer or the Trustee, respectively, unless such default shall have been cured or waived.

Section 8.06

Waiver of Servicer Defaults and Master Servicer Defaults.

The Master Servicer or the Trustee may waive only by written notice from Certificateholders evidencing 66-2/3 of the Voting Rights (unless such default materially and adversely affects all Certificateholders, in which case the written direction shall be from all of the Certificateholders) any default by the Servicer or the Master Servicer, respectively, in the performance of its obligations hereunder and its consequences. Upon any such waiver of a past default, such default shall cease to exist, and any Servicer Default or Master Servicing Default, as applicable, arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived in writing.

If a Master Servicer Default has occurred and has not been cured or waived, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and the same degree of care and skill in their exercise, as a prudent person would exercise under the circumstances in the conduct of such Person’s own affairs. The Securities Administrator undertakes to perform such duties and only such duties as are specifically set forth in this Agreement as duties of the Securities Administrator. The rights, duties and obligations of the Securities Administrator under this Agreement shall be of ▇▇▇▇▇ Fargo Bank, N.A. in its capacity as such and not in its capacity as Master Servicer hereunder.

In addition, the Securities Administrator agrees to notify the Trustee no later than 10:00 a.m. New York time on any Distribution Date of the failure of the Master Servicer to have made any required Advance pursuant to Section 3A.12 hereof.

(d)

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

(i)

Prior to the occurrence of a Master Servicer Default and after the curing or waiver of all the Master Servicer Defaults which may have occurred with respect to the Trustee, the duties and obligations of the Trustee and the Securities Administrator shall be determined solely by the express provisions of this Agreement, the Trustee and the Securities Administrator shall not be liable except for the performance of their respective duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee or the Securities Administrator and, in the absence of bad faith on the part of the Trustee or the Securities Administrator, the Trustee or the Securities Administrator, as applicable, may conclusively rely and shall be fully protected in acting or refraining from acting, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee or the Securities Administrator and conforming to the requirements of this Agreement;

(ii)

Neither the Trustee nor the Securities Administrator shall be liable in its individual capacity for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee or the Securities Administrator unless it shall be proved that the Trustee or the Securities Administrator, as applicable, was negligent in ascertaining the pertinent facts;

(iii)

Neither the Trustee nor the Securities Administrator shall be liable with respect to any action taken, suffered or omitted to be taken by it in good faith and believed by it to be authorized or within the rights or powers conferred upon it by this Agreement or in accordance with the directions of the Holders of Certificates evidencing not less than 25% of the aggregate Voting Rights of the Certificates, if such action or non-action relates to the time, method and place of conducting any proceeding for any remedy available to the Trustee or the Securities Administrator or exercising any trust or other power conferred upon the Trustee or the Securities Administrator under this Agreement;

(iv)

Neither the Trustee nor the Securities Administrator shall be required to take notice or be deemed to have notice or knowledge of any default, Servicer Default or Master Servicer Default unless a Responsible Officer of the Trustee or the Securities Administrator shall have actual knowledge thereof. In the absence of such notice, the Trustee and the Securities Administrator may conclusively assume there is no such default, Servicer Default or Master Servicer Default;

(v)

Neither the Trustee nor the Securities Administrator shall in any way be liable by reason of any insufficiency in any Account held by or in the name of Trustee or the Securities Administrator unless it is determined by a court of competent jurisdiction that the Trustee’s or the Securities Administrator’s, as applicable, gross negligence or willful misconduct was the primary cause of such insufficiency (except to the extent that the Trustee or the Securities Administrator is obligor and has defaulted thereon);

(vi)

Anything in this Agreement to the contrary notwithstanding, in no event shall the Trustee or the Securities Administrator be liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee or the Securities Administrator, as applicable, has been advised of the likelihood of such loss or damage and regardless of the form of action and whether or not any such damages were foreseeable or contemplated; and

(vii)

None of the Seller, the Depositor, the Master Servicer, the Servicer, the Securities Administrator or the Trustee shall be responsible for the acts or omissions of the other, it being understood that this Agreement shall not be construed to render them partners, joint venturers or agents of one another.

Neither the Trustee nor the Securities Administrator shall be required to expend or risk its own funds or otherwise incur liability, financial or otherwise, in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or 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 or the Securities Administrator to perform, or be responsible for the manner of performance of, any of the obligations of the terminated Master Servicer or terminated Servicer hereunder.

(e)

All funds received by the Securities Administrator and required to be deposited in the Distribution Account pursuant to this Agreement will be promptly so deposited by the Securities Administrator.

Nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of a Master Servicer Default of which a Responsible Officer of the Trustee has actual knowledge (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Agreement, and to use the same degree of care and skill in their exercise, as a prudent person would exercise under the circumstances in the conduct of his own affairs;

If any separate trustee or co-trustee or separate securities administrator or co-securities administrator 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 or the Securities Administrator, as applicable, to the extent permitted by law, without the appointment of a new or successor trustee or successor securities administrator.

Section 9.12

Tax Matters.

(b) the Securities Administrator shall apply for an employer identification number with the Internal Revenue Service via a Form SS-4 or other comparable method for each REMIC that is or becomes a taxable entity, and within thirty days of the Closing Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the holders of the Certificates may contact for tax information relating thereto, together with such additional information as may be required by such Form, and update such information at the time or times in the manner required by the Code for the Trust Fund; (c) the Securities Administrator shall make or cause to be made elections, on behalf of each REMIC formed hereunder to be treated as a REMIC on the federal tax return of such REMIC for its first taxable year (and, if necessary, under applicable state law); (d) the Securities Administrator shall prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and to the Internal Revenue Service and, if necessary, state tax authorities, all information returns and reports as and when required to be provided to them in accordance with the REMIC Provisions, including without limitation, the calculation of any original issue discount using the Prepayment Assumption; (e) the Securities Administrator shall provide information necessary for the computation of tax imposed on the transfer of a Residual Certificate to a Person that is not a Permitted Transferee, or an agent (including a broker, nominee or other middleman) of a Person that is not a Permitted Transferee, or a pass-through entity in which a Person that is not a Permitted Transferee is the record holder of an interest (the reasonable cost of computing and furnishing such information may be charged to the Person liable for such tax); (f) the Securities Administrator and the Trustee shall, to the extent under its control, conduct the affairs of the Trust Fund at all times that any Certificates are outstanding so as to maintain the status of each REMIC formed hereunder as a REMIC under the REMIC Provisions;

(h) the Securities Administrator shall pay, from the sources specified in the last paragraph of this Section 9.12, the amount of any federal, state and local taxes, including prohibited transaction taxes as described below, imposed on any REMIC formed hereunder prior to the termination of the Trust Fund when and as the same shall be due and payable (but such obligation shall not prevent the Securities Administrator or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Securities Administrator from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings); (i) the Trustee shall sign federal, state or local income tax or information returns or any other document prepared by the Securities Administrator pursuant to this Section 9.12 requiring a signature thereon by the Trustee; (j) the Securities Administrator shall maintain records relating to each REMIC formed hereunder including but not limited to the income, expenses, assets and liabilities of each such REMIC and adjusted basis of the Trust Fund property determined at such intervals as may be required by the Code, as may be necessary to prepare the foregoing returns, schedules, statements or information; (k) the Securities Administrator shall, for federal income tax purposes, maintain books and records with respect to the REMICs on a calendar year and on an accrual basis; (l) neither the Trustee nor the Securities Administrator shall enter into any arrangement not otherwise provided for in this Agreement by which the REMICs will receive a fee or other compensation for services nor permit the REMICs to receive any income from assets other than “qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined in Section 860G(a)(5) of the Code; and (m) as and when necessary and appropriate, the Securities Administrator shall represent the Trust Fund in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing authority, request an administrative adjustment as to any taxable year of any REMIC formed hereunder, enter into settlement agreements with any governmental taxing agency, extend any statute of limitations relating to any tax item of the Trust Fund, and otherwise act on behalf of each REMIC formed hereunder in relation to any tax matter involving any such REMIC.

In order to enable the Securities Administrator to perform its duties as set forth herein, the Depositor shall provide, or cause to be provided, to the Securities Administrator within 10 days after the Closing Date all information or data that the Securities Administrator requests in writing and determines to be relevant for tax purposes to the valuations and offering prices of the Certificates, including, without limitation, the price, yield, prepayment assumption and projected cash flows of the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide to the Securities Administrator promptly upon written request therefor, any such additional information or data that the Trustee may, from time to time, request in order to enable the Securities Administrator to perform its duties as set forth herein. The Depositor hereby indemnifies the Securities Administrator for any losses, liabilities, damages, claims or expenses of the Securities Administrator arising from any errors or miscalculations of the Securities Administrator that result from any failure of the Depositor to provide, or to cause to be provided, accurate information or data to the Securities Administrator on a timely basis.

In the event that any tax is imposed on “prohibited transactions” of any REMIC as defined in Section 860F(a)(2) of the Code, on the “net income from foreclosure property” of the Trust Fund as defined in Section 860G(c) of the Code, on any contribution to any REMIC after the startup day pursuant to Section 860G(d) of the Code, or any other tax is imposed, including, without limitation, any federal, state or local tax or minimum tax imposed upon any REMIC and is not paid as otherwise provided for herein, such tax shall be paid by (i) the Securities Administrator, if any such other tax arises out of or results from a breach by the Securities Administrator of any of its obligations under this Section, (ii) any party hereto (other than the Securities Administrator) to the extent any such other tax arises out of or results from a breach by such other party of any of its obligations under this Agreement or (iii) in all other cases, or in the event that any liable party hereto fails to honor its obligations under the preceding clauses (i) or (ii), any such tax will be paid first with amounts otherwise to be distributed to the Residual Certificateholders, and second with amounts otherwise to be distributed to all other Certificateholders in the following order of priority: first, to the Subordinate Certificates in reverse numerical order, and second, to the Senior Certificates (pro rata based on the amounts to be distributed). Notwithstanding anything to the contrary contained herein, to the extent that such tax is payable by the Holder of any Certificates, the Securities Administrator is hereby authorized to retain on any Distribution Date, from the Holders of the Residual Certificates (and, if necessary, second, from the Holders of the other Certificates in the priority specified in the preceding sentence), funds otherwise distributable to such Holders in an amount sufficient to pay such tax. The Securities Administrator shall include in its Remittance Report instructions as to distributions to such parties taking into account the priorities described in the second preceding sentence. The Securities Administrator agrees to promptly notify in writing the party liable for any such tax of the amount thereof and the due date for the payment thereof.

(1)

The Master Servicer (in the case of the exercise of the Cleanup Call) or the Depositor (in all other cases) shall establish a 90-day liquidation period and notify the Securities Administrator thereof, and the Securities Administrator shall in turn specify the first day of such period in a statement attached to the tax return for the Subsidiary REMIC pursuant to Treasury Regulation Section 1.860F-1.

The Depositor, the Servicer, the Seller, the Master Servicer, the Securities Administrator and the Trustee also may at any time and from time to time amend this Agreement without the consent of the Certificateholders to modify, eliminate or add to any of its provisions to such extent as shall be necessary or helpful to (i) maintain the qualification of any REMIC as a REMIC under the Code, (ii) avoid or minimize the risk of the imposition of any tax on any REMIC pursuant to the Code that would be a claim at any time prior to the final redemption of the Certificates or (iii) comply with any other requirements of the Code; provided, that the Trustee have been provided an Opinion of Counsel, which opinion shall be an expense of the party requesting such opinion, to the effect that such action is necessary or helpful to, as applicable, (i) maintain such qualification, (ii) avoid or minimize the risk of the imposition of such a tax or (iii) comply with any such requirements of the Code.

This Agreement may also be amended from time to time by the Depositor, the Servicer, the Seller, the Master Servicer, the Securities Administrator, the Trustee and ▇▇▇▇▇ Fargo Bank, N.A., as a Custodian, with the consent of the Holders of each Class of Certificates affected thereby evidencing 66% of the aggregate Certificate Principal Balance of such Class for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments required to be distributed on any Certificate without the consent of the Holder of such Certificate, or (ii) reduce the aforesaid percentages of Certificates the Holders of which are required to consent to any such amendment, without the consent of the Holders of all such Certificates then outstanding.

Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless they shall have first received an Opinion of Counsel, which opinion shall not be an expense of the Trustee or the Trust Fund, but shall be at the expense of the party requesting such amendment, to the effect that such amendment will not cause the imposition of any tax on any REMIC or the Certificateholders or cause any REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding.

Promptly after the execution of any amendment to this Agreement requiring the consent of Certificateholders, the Securities Administrator shall furnish written notification of the substance or a copy of such amendment to each Certificateholder and each Rating Agency.

It shall not be necessary for the consent of Certificateholders under this Section 11.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Securities Administrator may prescribe.

Nothing in this Agreement shall require the Trustee to enter into an amendment without receiving an Opinion of Counsel (which Opinion shall not be an expense of the Trustee or the Trust Fund), satisfactory to the Trustee that (i) such amendment is permitted and is not prohibited by this Agreement and that all requirements for amending this Agreement have been complied with; and (ii) either (A) the amendment does not adversely affect in any material respect the interests of any Certificateholder or (B) the conclusion set forth in the immediately preceding clause (A) is not required to be reached pursuant to this Section 11.01. Neither the Trustee nor the Securities Administrator shall have any obligation to consent to any amendment that it reasonably believes will materially and adversely affect its rights or immunities under this Agreement.

Section 11.02

Recordation of Agreement; Counterparts.

To the extent permitted by applicable law, this Agreement is subject to recordation in all appropriate public offices for real property records in all of the counties or other comparable jurisdictions in which any or all of the Mortgaged Properties are situated, and in any other appropriate public recording office or elsewhere. The Seller or the Depositor shall effect such recordation at the Trust’s expense upon the request in writing of a Certificateholder, but only if such direction is accompanied by an Opinion of Counsel (provided at the expense of the Certificateholder requesting recordation) to the effect that such recordation would materially and beneficially affect the interests of the Certificateholders or is required by law.

For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument.

Section 11.03

GOVERNING LAW.

THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT REGARD TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF (OTHER THAN THE PROVISIONS OF SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

Section 11.04

Intention of Parties.

It is the express intent of the parties hereto that the conveyance of the Mortgage Notes, Mortgages, assignments of Mortgages, title insurance policies and any modifications, extensions and/or assumption agreements and private mortgage insurance policies relating to the Mortgage Loans by the Seller to the Depositor, and by the Depositor to the Trust Fund be, and be construed as, an absolute sale thereof to the Depositor or the Trust Fund, as applicable. It is, further, not the intention of the parties that such conveyance be deemed a pledge thereof by the Seller to the Depositor, or by the Depositor to the Trust Fund. However, in the event that, notwithstanding the intent of the parties, such assets are held to be the property of the Seller or the Depositor, as applicable, or if for any other reason this Agreement is held or deemed to create a security interest in such assets, then (i) this Agreement shall be deemed to be a security agreement within the meaning of the Uniform Commercial Code of the State of New York and (ii) each conveyance provided for in this Agreement shall be deemed to be an assignment and a grant by the Seller or the Depositor, as applicable, for the benefit of the Certificateholders, of a security interest in all of the assets that constitute the Trust Fund, whether now owned or hereafter acquired.

The Depositor for the benefit of the Certificateholders shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the assets of the Trust Fund, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement.
