If the related Custodian finds that any document with respect to a Mortgage Loan has not been received, or is unrelated to the Mortgage Loans identified in Exhibit B or appears to be defective on its face, the Custodian shall note such defect in the exception report attached the final trust receipt issued pursuant to the Custodial Agreement and 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 of the defect 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.

(d) 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 detailing the components of the Purchase Price, signed by an authorized officer. Upon deposit of the Purchase Price in the Custodial Account and upon receipt of a request for release (in the form attached to the Custodial Agreement) with respect to such Mortgage Loan, the Custodian, on behalf of the Trustee, will 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. The Seller shall promptly reimburse the Trustee for any expenses incurred by the Trustee in respect of enforcing the remedies for such breach.

(e) The Seller shall deliver to the Custodian the Mortgage Note and other documents constituting the Mortgage File with respect to any Replacement Mortgage Loan, which the Custodian will review as provided in the Custodial Agreement, provided, that the Closing Date referred to therein shall instead be the date of delivery of the Mortgage File with respect to each Replacement Mortgage Loan.

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

(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) No Mortgage Loan is subject to the Home Ownership and Equity Protection Act of 1994 or any comparable law and no Mortgage Loan is classified and/or defined as a “high cost”, “covered”, “high risk home” or “predatory” loan under any other state, federal or local law or regulation or ordinance (or a similarly classified loan using different terminology under a law imposing heightened regulatory scrutiny or additional legal liability for residential mortgage loans having high interest rates, points and/or fees).

(ix) No loan is a High Cost Loan or Covered Loan, as applicable (as such terms are defined in Appendix E of the Standard & Poor’s Glossary For File Format For LEVELS® Version 5.6 Revised (attached hereto as Exhibit N) and no Mortgage Loan originated on or after October 1, 2002 through March 6, 2003 is governed by the Georgia Fair Lending Act.

(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 related Custodian of a request for release in accordance with the related Custodial Agreement. 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 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. Notwithstanding the foregoing, any breach of a representation or warranty contained in clauses (xxxvii), (xxxviii), (xxxix), (xl) and/or (xlv) of Section 8 of the Mortgage Loan Purchase Agreement shall be automatically deemed to materially and adversely affect the interests of the Certificateholders.

With respect to any Replacement Mortgage Loan or Loans, the Seller shall deliver to the related Custodian for the benefit of the Certificateholders such documents and agreements as are required by Section 2 of the related Custodial Agreement. 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 Master Servicer and the Securities Administrator. 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 and receipt by the related Custodian of a request for release for such Mortgage Loan in accordance with the related Custodial Agreement, the related Custodian on behalf of the Trustee shall release to the Seller the Mortgage File relating to such Deleted Mortgage Loan and held for the benefit of the Certificateholders and the Trustee shall execute and deliver at the Seller’s direction such instruments of transfer or assignment as have been prepared by the Seller, 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 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 Securities Administrator 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 remitted to the Servicer for deposit in the Custodial Account by the Seller delivering such Replacement Mortgage Loan on or before the Determination Date for the Distribution Date relating to the Prepayment Period during which the related Mortgage Loan was required to be purchased or replaced hereunder.

In the event that the Seller shall be required to repurchase a Mortgage Loan, the Purchase Price therefor shall be remitted to the Servicer for deposit in the Custodial Account, on or before the Determination Date immediately following the date on which the Seller was required to repurchase such Mortgage Loan. The Purchase Price shall be remitted by the Servicer to the Securities Administrator on the Remittance Date occurring in the month immediately following the month in which the Purchase Price was deposited in the Custodial Account. In addition, upon such deposit of the Purchase Price, the delivery of an Officer’s Certificate by the Servicer to the Trustee certifying that the Purchase Price has been deposited in the Custodial Account, the delivery of an Opinion of Counsel if required by Section 2.05 and the receipt of a Request for Release, the Trustee 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 or is continuing shall constitute the sole remedies against the Seller respecting such breach available to Certificateholder, the Depositor or the Trustee.

(iv) The Master Servicer does not believe, nor does it have any reason or cause to believe, that it cannot perform each and every covenant made by it and contained in this Agreement;

ARTICLE III

ADMINISTRATION AND SERVICING OF THE MORTGAGE LOANS; ACCOUNTS

Section 3.01

The Servicer to act as Servicer of the Mortgage Loans.

The Servicer shall service and administer the Mortgage Loans 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 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 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 3.27, and further as provided in Section 3.32. 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 Mortgagor 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 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 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 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 its 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 Mortgage Loans itself. In the event that the Servicer’s responsibilities and duties under this Agreement are terminated pursuant to Section 8.01, 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 neither the Master Servicer nor the Trustee shall have any obligations, duties or liabilities with respect to such subservicer including any obligation, duty or liability of the Master Servicer 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 as required by this Agreement all documents and instruments in respect of a Mortgage Loan coming into the possession of the Servicer from time to time and shall account fully to the Securities Administrator 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 3.27. 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 a Mortgaged Property or REO Property is at any time in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards and flood insurance has been made available, the Servicer 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 maintained by the Servicer 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 Fannie Mae or Freddie Mac if it were the purchaser of the Mortgage Loans, unless the Servicer has obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Servicer shall provide the Master Servicer, upon request, with copies of such insurance policies and fidelity bond (or waiver thereof). The Servicer shall also maintain a fidelity bond in the form and amount that would meet the requirements of Fannie Mae or Freddie Mac, unless the Servicer has obtained a waiver of such requirements from Fannie Mae 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, 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

Reserved.

Section 3.09 Realization Upon Defaulted Mortgage Loans; Determination of Excess Liquidation Proceeds and Realized Losses; Repurchases of Certain Mortgage Loans.

(a) 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. 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 (i) 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 (ii) 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). If the Servicer reasonably believes that Liquidation Proceeds with respect to any such Mortgage Loan would not be increased as a result of such foreclosure or other action, such Mortgage Loan will be charged-off and will become a Liquidated Loan. The Servicer will give notice of any such charge-off to the Securities Administrator. 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, as contemplated in Section 3.27. 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.

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 Securities Administrator 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 and the Securities Administrator shall be supplied with an Opinion of Counsel (such opinion not to be an expense of the Trustee, the Securities Administrator 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 REMIC I or REMIC II as defined in section 860F of the Code or cause either REMIC I or REMIC II 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 either REMIC I or REMIC II 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, unreimbursed 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 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 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 and Servicing Fees, pursuant to Section 3.27 or this Section 3.09; second, to reimburse the Servicer for any unreimbursed Advances, pursuant to Section 3.27 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 the same to the Securities Administrator pursuant to Section 3.28.

(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 3.27.

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 3.27. 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 3.27.

Section 3.11

REO Property.

(a) In the event the Trust Fund acquires ownership of any REO Property in respect of any related Mortgage Loan, the deed or certificate of sale shall be issued to the Trustee, or to its nominee, on behalf of the related Certificateholders. The Servicer shall sell any REO Property as expeditiously as possible and in accordance with the provisions of this Agreement. Pursuant to its efforts to sell such REO Property, the Servicer shall protect and conserve such REO Property in the manner and to the extent required herein, in accordance with the REMIC Provisions.

(b) The Servicer shall deposit all funds collected and received in connection with the operation of any REO Property into the Custodial Account.

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

Section 3.12

Liquidation Reports.

Upon the foreclosure of any Mortgaged Property or the acquisition thereof by the Trust Fund pursuant to a deed-in-lieu of foreclosure, the Servicer shall submit a liquidation report to the Trustee containing such information as shall be mutually acceptable to the Servicer and the Trustee with respect to such Mortgaged Property.

Section 3.13

Annual Certificate as to Compliance.

(a) The Servicer shall deliver to the Depositor, the Master Servicer, the Securities Administrator and each Rating Agency not later than March 15^th of each year commencing in 2006 (or, in each case, if such day is not a Business Day, the immediately preceding Business Day), a certificate of a Authorized Servicer Representative stating, as to each signatory thereof, that (i) a review of the activities of the Servicer during the preceding calendar year and of performance under this Agreement has been made under such officers’ supervision, and (ii) to the best of such officers’ knowledge, based on such review, the Servicer has fulfilled all of its obligations under this Agreement throughout such year, or, if there has been a default in the fulfillment of any such obligation, specifying each such default known to such officers and the nature and status thereof except for such defaults as such officer in its good faith judgment believe to be immaterial.

(b) (i) The Servicer shall deliver to the Depositor, the Master Servicer, the Securities Administrator, on or before March 15^th of each year commencing in 2006, a certification containing the information set forth in Exhibit L. Such certification shall be signed by the senior officer in charge of servicing of the Servicer. In addition, the Servicer shall provide such other information with respect to the Mortgage Loans and the servicing and administration thereof within the control of the Servicer which shall be required to enable the Depositor and the Trustee to comply with the reporting requirements of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”).

(ii) The Servicer shall indemnify and hold harmless the Depositor, the Master Servicer, the Securities Administrator and their respective officers, directors, agents and affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments and other costs and expenses to the extent arising out of or based upon a breach by the Servicer or any of its officers, directors, agents or affiliates of its obligations under this Section 3.13(b), or a breach in any of the representations in the certification delivered pursuant to clause (b)(i) above, or the Servicer’s gross negligence, bad faith or willful misconduct in connection therewith. If

the indemnification provided for herein is unavailable to the Depositor, the Master Servicer and the Securities Administrator as a result of a court of law or other administrative or regulatory body with authority holding such indemnification void on the basis of public policy or similar reason or insufficient to hold harmless the Depositor, the Master Servicer or the Securities Administrator, then the Servicer agrees that it shall contribute to the amount paid or payable by the Depositor, the Master Servicer and the Securities Administrator as a result of the losses, claims, damages or liabilities of the Depositor or the Securities Administrator in such proportion as is appropriate to reflect the relative fault of the Securities Administrator or the Depositor on the one hand and the Servicer on the other in connection with a breach of the Servicer’s obligations under this Section 3.13(b) or the Servicer’s gross negligence, bad faith or willful misconduct in connection therewith or a breach of any of the representations in the certification delivered pursuant to clause (b)(i) above with respect to the matters covered by this Section 3.13(b)(ii).

Section 3.14

Annual Independent Certified Public Accountants’ Servicing Report.

Not later than March 15th of each year, commencing in 2006, the Servicer, at its expense, shall cause a nationally recognized firm of independent certified public accountants to furnish to the Servicer a report stating that (i) it has obtained a letter of representation regarding certain matters from the management of the Servicer which includes an assertion that the Servicer has complied with certain minimum residential mortgage loan servicing standards, identified in the Uniform Single Attestation Program for Mortgage Bankers established by the Mortgage Bankers Association of America, with respect to the servicing of residential mortgage loans during the most recently completed fiscal or calendar year and (ii) on the basis of an examination conducted by such firm in accordance with standards established by the American Institute of Certified Public Accountants, such representation is fairly stated in all material respects, subject to such exceptions and other qualifications that may be appropriate. In rendering its report such firm may rely, as to matters relating to the direct servicing of residential mortgage loans by subservicers, upon comparable reports of firms of independent certified public accountants rendered on the basis of examinations conducted in accordance with the same standards (rendered within one year of such report) with respect to those subservicers. Promptly upon receipt of such report, the Servicer shall furnish a copy of such report to the Depositor, the Master Servicer, the Securities Administrator and each Rating Agency. Copies of such statement shall be provided by the Securities Administrator to any Certificateholder upon request at the Servicer’s expense, provided that such statement is delivered by the Servicer to the Securities Administrator.

Section 3.15

Books and Records.

The Servicer shall be responsible for maintaining, and shall maintain, a complete set of books and records for the Mortgage Loans which shall be appropriately identified in the Servicer’s computer system to clearly reflect the ownership of the Mortgage Loans by the Trust. In particular, the Servicer shall maintain in its possession, available for inspection by the Trustee and the Master Servicer and shall deliver to the Trustee or the Master Servicer upon reasonable prior request and during normal business hours, evidence of compliance with all federal, state and local laws, rules and regulations. To the extent that original documents are not required for purposes of realization of Liquidation Proceeds or Insurance Proceeds, documents maintained by the Servicer may be in the form of microfilm or microfiche or such other reliable means of

recreating original documents, including, but not limited to, optical imagery techniques so long as the Servicer complies with the requirements of Accepted Servicing Practices.

The Servicer shall maintain with respect to each Mortgage Loan and shall upon reasonable prior request and during normal business hours make available for inspection by the Trustee and the Master Servicer the related servicing file during the time such Mortgage Loan is subject to this Agreement and thereafter in accordance with applicable law.

Section 3.16

The Trustee.

The Trustee shall furnish the Servicer with any powers of attorney and other documents prepared and submitted by the Servicer to the Trustee in a form as mutually agreed upon and necessary or appropriate to enable the Servicer to service and administer the related Mortgage Loans and REO Properties.

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

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

In particular, the Trustee shall not (a) knowingly sell or permit the sale of all or any portion of the Mortgage Loans or of any investment of deposits in an Account unless such sale is as a result of a repurchase of the Mortgage Loans pursuant to this Agreement or the Trustee has received a REMIC Opinion prepared at the expense of the Trust Fund; and (b) other than with respect to a substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as applicable, accept any contribution to any REMIC after the Startup Day without receipt of a REMIC Opinion.

Section 3.19

Release of Mortgage Files.

(a) Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by the Servicer of a notification that payment in full has been escrowed in a manner customary for such purposes for payment to Certificateholders on the next Distribution Date, the Servicer will (or if the Servicer does not, the Master Servicer may) promptly furnish to the Trustee and the related Custodian, on behalf of the Trustee, two copies of a request for release substantially in the form attached to the related Custodial Agreement signed by a Authorized Servicer Representative or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Authorized Servicer Representative (which certification shall include a statement to the effect that all amounts received in connection with such payment that are required to be deposited in the Custodial Account pursuant to Article V have been or will be so deposited) and shall request that the related Custodian, on behalf of the Trustee, deliver to the Servicer the related Mortgage File. Within five (5) Business Days of receipt of such certification and request, the related Custodian, on behalf of the Trustee, shall release the related Mortgage File to the Servicer and the Trustee and the related Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, the Servicer is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the related Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the Custodial Account.

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

Section 3.20 Documents, Records and Funds in Possession of the Servicer to be held for Trustee.

(a) The Servicer (to the extent required by this Agreement) shall transmit to the Trustee or to related Custodian such documents and instruments coming into the possession of such Person from time to time as are required by the terms hereof to be delivered to the Trustee or the related Custodian. Any funds received by the Servicer in respect of any Mortgage

Loan or which otherwise are collected by the Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit of the Trustee and the Certificateholders subject to the right of the Servicer to retain its Servicing Fee and other amounts as provided in this Agreement.

Section 3.21

Possession of Certain Insurance Policies and Documents.

The Servicer shall retain possession and custody of the originals (to the extent available) of any Insurance Policies, or certificate of insurance if applicable, and any certificates of renewal as to the foregoing as may be issued from time to time as contemplated by this Agreement. Until all amounts distributable in respect of the Certificates have been distributed in full, the Trustee (or the related Custodian, as directed by the Trustee) shall retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions of this Agreement.

Section 3.22	[Reserved].
Section 3.23	UCC.

The Seller agrees to execute and file continuation statements for any Uniform Commercial Code financing statements which the Seller has informed the Trustee were filed on the Closing Date in connection with the Trust. The Seller shall file any financing statements or amendments and continuation statements thereto required by any change in the Uniform Commercial Code.

Section 3.24

Optional Purchase of Defaulted Mortgage Loans.

With respect to any Mortgage Loan which is delinquent in payment by ninety-one (91) days or more or is an REO Property, the Seller shall have the right to purchase such Mortgage Loan or REO Property from the Trust at a price equal to the Purchase Price. The Purchase Price shall be remitted to the Servicer for deposit in the Custodial Account and remitted by the Servicer to the Securities Administrator on the Servicer Remittance Date in the month immediately following the month in which the Purchase Price was deposited in the Custodial Account.

If at any time the Seller remits to the Servicer a payment for deposit in the Custodial Account covering the amount of the Purchase Price for such a Mortgage Loan and the Servicer delivers an Officer’s Certificate to the Trustee certifying that the Purchase Price has been deposited in the Custodial Account, the Trustee shall execute the assignment of such Mortgage Loan at the request of the Seller without recourse to the Seller which shall succeed to all the Trustee’s, right, title and interest in and to such Mortgage Loan, and all security and documents relative thereto. Such assignment shall be an assignment outright and not for security. The Seller will thereupon own such Mortgage, and all such security and documents, free of any further obligation to the Trustee or the Certificateholders with respect thereto. The Seller shall be responsible for any transfer costs incurred with respect to a Mortgage Loan purchased pursuant to this Section 3.24.

Section 3.25

Obligations of the Servicer Under Credit Risk Management Agreement.

Notwithstanding anything in this Agreement or the Credit Risk Management Agreements to the contrary, the Trustee shall not have any duty or obligation to enforce any Credit Risk Management Agreement or to supervise, monitor or oversee the activities of the Credit Risk Manager or the Servicer under the Credit Risk Management Agreements or this Agreement with respect to any action taken or not taken by the Servicer pursuant to a recommendation of the Credit Risk Manager or otherwise in connection with obligations of the Servicer under the related Credit Risk Management Agreement.

Section 3.26

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 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 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 and the Securities Administrator 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 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 USA, National Association, as trustee for registered holders of Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series 2005-AR4.” 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 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 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 3.26(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;

(viii) the Purchase Price with respect to any Mortgage Loans purchased by the Seller pursuant to Section 2.02 or 2.03, any amounts which are to be treated pursuant to Section 2.04 of this Agreement as the payment of such a Purchase Price and the Purchase Price with respect to any Mortgage Loans purchased by the Seller pursuant to Section 3.24; and

(ix)	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 3.27, 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 3.27.

(c) The institution that maintains the Custodial Account with respect to the Mortgage Loans, 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 Servicer’s 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 Securities Administrator, the Master Servicer the Seller, each Rating Agency and the Depositor of any proposed change of location of the Custodial Account relating to the Mortgage Loans prior to any change thereof.

Section 3.27

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 3.27(b), any unreimbursed Advances to the extent of Amounts Held For Future Distribution funds held in the Custodial Account relating to the Mortgage Loans that were not included in the Available Distribution Amount for the preceding Distribution Date;

(iii) to reimburse itself or an Advance Financing Person for any Nonrecoverable Advances;

(iv) to reimburse itself from Insurance Proceeds for Insured Expenses covered by the related Insurance Policy;

(v) to pay itself any unpaid Servicing Fees and to reimburse itself 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 or the Depositor with respect to each Mortgage Loan or property acquired in respect thereof that has been purchased pursuant to Section 2.02, 2.03 or 3.24, 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 pursuant to Section 7.04;

(viii) to withdraw any amount deposited in the Custodial Account relating to the Mortgage Loans and not required to be deposited therein; and

(ix) to clear and terminate the Custodial Account relating to the Mortgage Loans upon termination of this Agreement pursuant to Section 10.01 hereof.

In addition, no later than noon 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 3.27(a)), 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 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 of 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 the Custodial Account relating to the Mortgage Loans 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 3.27(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 related 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 amount at any time credited to the Custodial Account may be invested by the Servicer in Permitted Investments.

Section 3.29

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

To the extent required by the Mortgage Note related to a Mortgage Loan, 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.

The Servicer shall execute and deliver the notices required by each Mortgage and Mortgage Note, applicable laws and regulations regarding interest rate adjustments. The Servicer shall also provide timely notification to the Master Servicer of all applicable data and information regarding such interest rate adjustments and the Servicer’s methods of implementing such interest rate adjustments. Upon the discovery by the Servicer or the Master Servicer that the Servicer has failed to adjust a Mortgage Rate or a Scheduled Payment pursuant to the terms of the related Mortgage Note and Mortgage, the Servicer shall immediately deposit in the Custodial Account from its own funds the amount of any interest loss caused thereby without reimbursement therefor.

Duties of the Credit Risk Manager; Termination.

(a) The Depositor appoints Risk Management Group, LLC 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 related Credit Risk Management Agreement and the Credit Risk Manager shall look solely to the Servicer and/or Master Servicer for all information and data (including loss and delinquency information and data) and loan level information and data relating to the servicing of the related 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 Trustee, each Rating Agency and the Credit Risk Manager. Notwithstanding the foregoing, the termination of the Credit Risk Manager pursuant to Section 3.33(b) 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 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 Servicer, the Securities Administrator and the Credit Risk Manager.

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.

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 Servicer, 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 and/or Master Servicer under the related 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 and/or Master Servicer pursuant to the Credit Risk Management Agreement in the performance of its duties thereunder and hereunder.

ARTICLE IV

ADMINISTRATION AND MASTER SERVICING OF THE MORTGAGE LOANS

Section 4.01

The Master Servicer.

The Master Servicer shall supervise, monitor and oversee the obligation of the Servicer to service and administer the Mortgage Loans in accordance with the terms of this Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices. Furthermore, the Master Servicer shall oversee and consult with the Servicer as necessary from time-to-time to carry out the Master Servicer’s obligations hereunder, shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by the Servicer and shall cause the Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by the Servicer under this Agreement. The Master Servicer shall independently and separately monitor the Servicer’s servicing activities with respect to each Mortgage Loan, reconcile the results of such monitoring with such information provided in the previous sentence on a monthly basis and coordinate corrective adjustments to the Servicer’s and Master Servicer’s records, and based on such reconciled and corrected information, provide such information relating to the Mortgage Loans to the Securities Administrator as shall be necessary to enable it to prepare the statements specified in Section 5.06 and any other information and statements required to be provided by the Securities Administrator hereunder. The Master Servicer shall reconcile the results of its Mortgage Loan monitoring with the actual remittances of the Servicer to the Distribution Account.

Notwithstanding anything in this Agreement to the contrary, the Master Servicer shall not have any duty or obligation to enforce any Credit Risk Management Agreement that the Servicer is a party to (the “Servicer Credit Risk Management Agreement”) or to supervise, monitor or oversee the activities of the Credit Risk Manager under the Servicer Credit Risk Management Agreement with respect to any action taken or not taken by the Servicer pursuant to a recommendation of the Credit Risk Manager.

The Trustee shall furnish the Servicer and the Master Servicer with any limited powers of attorney and other documents in form as provided to it necessary or appropriate to enable the Servicer and the Master Servicer to service or master service and administer the Mortgage Loans and REO Property. The Trustee shall have no responsibility for any action of the Master Servicer or the Servicer pursuant to any such limited power of attorney and shall be indemnified by the Master Servicer or the Servicer for any cost, liability or expense arising from the misuse thereof by the Master Servicer or the Servicer.

The Trustee, the Custodians and the Securities Administrator shall provide access to the records and documentation in possession of the Trustee, the Custodians or the Securities Administrator regarding the Mortgage Loans and REO Property and the servicing thereof to the Certificateholders, the FDIC, and the supervisory agents and examiners of the FDIC, such access being afforded only upon reasonable prior written request and during normal business hours at the office of the Trustee, the Custodians or the Securities Administrator; provided, however, that, unless otherwise required by law, none of the Trustee, the Custodians or the Securities

Administrator shall be required to provide access to such records and documentation if the provision thereof would violate the legal right to privacy of any Mortgagor. The Trustee, the Custodians and the Securities Administrator shall allow representatives of the above entities to photocopy any of the records and documentation and shall provide equipment for that purpose at a charge that covers the Trustee’s, the Custodians’ or the Securities Administrator’s actual costs.

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

Section 4.02

Monitoring of Servicer.

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

The Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of the Servicer under this Agreement, and shall, in the event that the Servicer fails to perform its obligations in accordance with the Servicing Agreement, subject to this Section and Article VIII, shall terminate the rights and obligations of the Servicer hereunder in accordance with the provisions of Article VIII . The Master Servicer shall act as servicer of the Mortgage Loans or enter in to a new servicing agreement with a successor servicer selected by the Master Servicer; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to the Master Servicer or such successor servicer. Such enforcement, including, without limitation, the legal prosecution of claims and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received indemnity reasonably acceptable to it for its costs and expenses in pursuing such action.

To the extent that the costs and expenses related to the termination of the Servicer, appointment of a successor servicer or the transfer and assumption of servicing by the Master Servicer (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the Servicer as a result

of an event of default by the Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor servicer to service the Mortgage Loans in accordance with this Agreement) are not fully and timely reimbursed by the terminated Servicer, the Master Servicer shall be entitled to reimbursement of such costs and expenses from the Distribution Account.

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

If the Master Servicer acts as Servicer, it shall not assume liability for the representations and warranties of the Servicer, if any, that it replaces.

Section 4.03

Fidelity Bond.

The Master Servicer, at its expense, shall maintain in effect a blanket fidelity bond and an errors and omissions insurance policy that shall be in such form and amount generally acceptable for entities serving as master servicers or trustees, affording coverage with respect to all directors, officers, employees and other Persons acting on such Master Servicer’s behalf, and covering errors and omissions in the performance of the Master Servicer’s obligations hereunder. Any such errors and omissions policy and fidelity bond may not be cancelable without thirty (30) days’ prior written notice to the Trustee.

Section 4.04

Power to Act; Procedures.

The Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Section 9.13 hereof, to do any and all things that it may deem necessary or desirable in connection with the master servicing and administration of the Mortgage Loans, including but not limited to the power and authority (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Loan, in each case, in accordance with the provisions of this Agreement; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 4.02, shall not permit the Servicer to) knowingly or intentionally take any action, or fail to take (or fail to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, would cause any REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon the Trust Fund (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) unless the Master Servicer has received an Opinion of Counsel (but not at the expense of the Master Servicer) to the effect that the contemplated action will not cause any REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon any REMIC. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer or an Authorized Servicer Representative, with any powers of attorney empowering the Master Servicer, or the

Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer or the Servicer may request, to enable the Master Servicer to master service and administer the Mortgage Loans and carry out its duties hereunder, in each case in accordance with Accepted Master Servicing Practices (and the Trustee shall have no liability for the misuse of any such powers of attorney by the Master Servicer or the Servicer and shall be indemnified by the Master Servicer or the Servicer, as applicable, for any costs, liabilities or expenses incurred by the Trustee in connection with such misuse). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 9.10 hereof. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action authorized pursuant to this Agreement to be taken by it in the name of the Trustee, be deemed to be the agent of the Trustee.

Section 4.05

Due-on-Sale Clauses; Assumption Agreements.

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

Section 4.06 Documents, Records and Funds in Possession of Master Servicer To Be Held for Trustee.

The Master Servicer shall transmit to the Trustee or Custodians such documents and instruments coming into the possession of the Master Servicer from time to time as are required by the terms hereof to be delivered to the Trustee or the related Custodian. Any funds received by the Master Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer as Liquidation Proceeds, Insurance Proceeds or Subsequent Recoveries in respect of any Mortgage Loan shall be held for the benefit of the Trustee and the Certificateholders subject to the Master Servicer’s right to retain or withdraw from the Distribution Account the Master Servicing Compensation and other amounts provided in this Agreement. The Master Servicer, to the extent required by Article III, shall cause the Servicer to, provide access to information and documentation regarding the Mortgage Loans to the Trustee, its agents and accountants at any time upon reasonable request and during normal business hours, and to Certificateholders that are savings and loan associations, banks or insurance companies, the OTS, the FDIC and the supervisory agents and examiners of such Office and Corporation or examiners of any other federal or state banking or insurance regulatory authority if so required by applicable regulations of the OTS or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during normal

business hours at the offices of the Master Servicer designated by it. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

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

Section 4.07

Standard Hazard Insurance and Flood Insurance Policies.

For each Mortgage Loan, the Master Servicer shall enforce any obligation of the Servicer under this Agreement to maintain or cause to be maintained standard fire and casualty insurance and, where applicable, flood insurance, all in accordance with the provisions of this Agreement.

Pursuant to Section 3.31, any amounts collected by the Master Servicer, under any insurance policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or released to the Mortgagor in accordance with this Agreement) shall be deposited into the Distribution Account, subject to withdrawal pursuant to Section 3.32.

Section 4.08

Any proceeds disbursed to the Master Servicer (or disbursed to the Servicer and remitted to the Master Servicer) in respect of such policies, bonds or contracts shall be promptly deposited in the Distribution Account upon receipt, except that any amounts realized that are to be applied to the repair or restoration of the related Mortgaged Property as a condition precedent to the presentation of claims on the related Mortgage Loan to the insurer under any applicable insurance policy need not be so deposited (or remitted).

Section 4.09

Maintenance of the Primary Mortgage Insurance Policies.

The Master Servicer shall not take, or (to the extent within its control) permit the Servicer (to the extent such action is prohibited under this Agreement) to take, any action that would result in noncoverage under any primary mortgage insurance policy or any loss which, but for the actions of such Master Servicer or the Servicer, would have been covered thereunder. The Master Servicer shall use its best reasonable efforts to cause the Servicer to keep in force and effect (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance),

primary mortgage insurance applicable to each Mortgage Loan in accordance with the provisions of this Agreement. The Master Servicer shall not, and (to the extent within its control) shall not permit the Servicer to, cancel or refuse to renew any primary mortgage insurance policy that is in effect at the date of the initial issuance of the Mortgage Note and is required to be kept in force hereunder except in accordance with the provisions of this Agreement.

The Master Servicer agrees to cause the Servicer to present, on behalf of the Trustee and the Certificateholders, claims to the insurer under any primary mortgage insurance policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any primary mortgage insurance policies respecting defaulted Mortgage Loans. Pursuant to Section 3.31, any amounts collected by the Master Servicer or the Servicer under any primary mortgage insurance policies shall be deposited by the Servicer or by the Master Servicer in the Distribution Account, subject to withdrawal pursuant to Section 3.32.

Section 4.10 Trustee to Retain Possession of Certain Insurance Policies and Documents.

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

Section 4.11

Realization Upon Defaulted Loans.

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

Section 4.12

Compensation for the Master Servicer.

As compensation for its services hereunder, the Master Servicer shall be entitled to receive all income and gain realized from any investment of funds in the Distribution Account (the “Master Servicing Compensation”). The Master Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor except as provided in this Agreement.

The amount of the Master Servicing Compensation payable to the Master Servicer in respect of any Distribution Date shall be reduced in accordance with Section 4.18.

Section 4.13

REO Property.

In the event the Trust Fund acquires ownership of any REO Property in respect of any Mortgage Loan, the deed or certificate of sale shall be issued to the Trustee, or to its nominee, on behalf of the Certificateholders. The Master Servicer shall cause the Servicer to sell, and the Servicer agrees to sell, any REO Property as expeditiously as possible and in accordance with the provisions of this Agreement. Further, the Master Servicer shall cause the Servicer to sell any REO Property prior to three years after the end of the calendar year of its acquisition by REMIC I, unless (i) the Trustee and the Securities Administrator shall have been supplied with an Opinion of Counsel to the effect that the holding by the Trust Fund of such REO Property subsequent to such three-year period will not result in the imposition of taxes on “prohibited transactions” of any REMIC hereunder as defined in Section 860F of the Code or cause any REMIC hereunder 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) or (ii) the Servicer shall have applied for, prior to the expiration of such three-year period, an extension of such three-year period in the manner contemplated by Section 856(e)(3) of the Code, in which case the three-year period shall be extended by the applicable extension period. The Master Servicer shall cause the Servicer to protect and conserve, such REO Property in the manner and to the extent required by this Agreement, in accordance with the REMIC Provisions and in a manner that does not result in a tax on “net income from foreclosure property” or cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code.

The Master Servicer shall cause the Servicer to deposit all funds collected and received in connection with the operation of any REO Property in the Custodial Account.

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

such year, or, if there has been a material default in the performance or fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof.

Copies of such statements shall be provided to any Certificateholder upon request by the Master Servicer, or by the Trustee at the expense of the Master Servicer if the Master Servicer shall fail to provide such copies (unless (i) the Master Servicer shall have failed to provide the Trustee with such statement or (ii) the Trustee shall be unaware of the Master Servicer’s failure to provide such statement). 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 4.16

Within 15 days after each Distribution Date, the Securities Administrator shall, in accordance with industry standards, file with the Commission via the Electronic Data Gathering and Retrieval System (“EDGAR”), a Form 8-K with a copy of the statement furnished by the Securities Administrator to the Certificateholders for such Distribution Date as an exhibit thereto.

ARTICLE V

ADVANCES AND DISTRIBUTIONS

Section 5.01

Advances; Advance Facility.

(a) The Servicer shall make an Advance with respect to any Mortgage Loan and deposit such Advance in the Distribution Account no later than noon Eastern time on the Remittance Date in immediately available funds. The Servicer shall be obligated to make any such Advance only to the extent that such advance would not be a Nonrecoverable Advance. 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 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 Securities Administrator 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 3.27. 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.

Subject to and in accordance with the provisions of Article VIII hereof, in the event that the Servicer fails to make such Advance, then the Master Servicer, as a Successor 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 5.01 and 8.02.

(b) (i) 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 Trustee, the Securities Administrator, the Master Servicer, the Certificateholders or any other party shall be required before the Servicer may enter into an Advance Facility nor shall the Trustee, the Securities Administrator, the Master Servicer 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 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 and the Securities Administrator at the address set forth in Section 11.05 hereof no later than the 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 3.27 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 3.27 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 3.27 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 3.27 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 related 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 3.27 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 3.31 hereof, and (ii) none of 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 the Servicer’s Assignee, as applicable, shall be entitled pursuant to Section 3.27 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 Trustee in the manner set forth in Section 11.05 hereof. None of the Depositor, 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, 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 the Servicer’s Assignee. The Servicer shall indemnify the Master Servicer, the Securities Administrator, Depositor, the Trustee, 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 gross negligence, recklessness or willful misconduct on the part of the Master Servicer, the Securities Administrator, Depositor, the Trustee or any successor Servicer, as the case may be. The Servicer shall maintain and provide to any successor Servicer and, upon request, the Trustee 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 the 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 Master Servicer, the Securities Administrator, the Trustee, the Depositor 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 none of the Master Servicer, the Securities Administrator, the Trustee or the Trust are, 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) none of the Master Servicer, the Securities Administrator or the Trustee shall have any responsibility to track or monitor the administration of the financing arrangement between the Servicer and any Advance Financing Person.

Section 5.05

Allocation of Realized Losses.

(a) On or prior to each Determination Date, the Securities Administrator shall determine the amount of any Realized Loss in respect of each Mortgage Loan that occurred during the immediately preceding calendar month, based solely on the reports delivered by the Servicer pursuant to this Agreement.

(b) The interest portion of Realized Losses on the Mortgage Loans shall be allocated to the Certificates as described in Section 1.02 hereof.

(c) The principal portion of all Realized Losses on the Mortgage Loans shall be allocated on each Distribution Date as follows: first, in reduction of the Monthly Excess Cashflow; second, to the Class X Certificates, until the Certificate Principal Balance thereof has been reduced to zero; third, to the Class M-5 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fourth, to the Class M-4 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fifth, to the Class M-3 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; sixth, to the Class M-2 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; seventh, to the Class M-1 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; eighth, with respect to Realized Losses on the Group III Mortgage Loans only, to the Class III-A-2 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; ninth, with respect to Realized Losses on the Group IV Mortgage Loans only, to the Class IV-A-

2 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; and tenth, with respect to Realized Losses on the Group V Mortgage Loans only, to the Class V-A-4 Certificates, until the Certificate Principal Balance thereof has been reduced to zero. All such Realized Losses to be allocated to the Certificate Principal Balances of the Class III-A-2, Class IV-A-2 and Class V-A-4 Certificates and all Classes of Subordinate Certificates on any Distribution Date shall be so allocated after the actual distributions to be made on such date as provided above. All references above to the Certificate Principal Balance of any Class III-A-2, Class IV-A-2 and Class V-A-4 Certificates or any Class of Subordinate Certificates shall be to the Certificate Principal Balance of such Class immediately prior to the relevant Distribution Date, before reduction thereof by any Realized Losses, in each case to be allocated to such Class of Certificates, on such Distribution Date.

Any allocation of the principal portion of Realized Losses to a Class III-A-2, Class IV-A-2, Class V-A-4 or a Subordinate Certificate on any Distribution Date shall be made by reducing the Certificate Principal Balance thereof by the amount so allocated; any allocation of Realized Losses to a Class X Certificate shall be made by reducing the amount otherwise payable in respect thereof pursuant to Section 5.04(iii)(14). No allocations of any Realized Losses shall be made to the Certificate Principal Balances of the Class I-A, Class II-A, Class III-A-1, Class IV-A-1, Class V-A-1, Class V-A-2, Class V-A-3 or Class P Certificates.

All such Realized Losses and all other losses allocated to a Class of Certificates hereunder will be allocated among the Certificates of such Class in proportion to the Percentage Interests evidenced thereby.

(d) Notwithstanding anything to the contrary contained herein, if on any Distribution Date the Securities Administrator discovers, based solely on the reports delivered by the Servicer under this Agreement that any Subsequent Recoveries have been collected by the Servicer with respect to the Mortgage Loans, the amount of such Subsequent Recoveries will be applied to increase the Certificate Principal Balance of (i) the Class III-A-2 Certificates with respect to Subsequent Recoveries relating to the Group III Mortgage Loans, (ii) the Class IV-A-2 Certificates with respect to Subsequent Recoveries relating to the Group IV Mortgage Loans, (iii) the Class V-A-4 Certificates with respect to Subsequent Recoveries relating to the Group V Mortgage Loans and (iv) the Class of Subordinate Certificates with the highest payment priority to which Realized Losses on the Mortgage Loans have been allocated, but not by more than the amount of Realized Losses previously allocated to the Class III-A-2, Class IV-A-2, Class V-A-4 Certificates or that Class of Subordinate Certificates pursuant to this Section 5.05. After the Certificate Principal Balances of the Class III-A-2, Class IV-A-2 and Class V-A-4 Certificates have been increased up to the amount of Realized Losses allocated thereto pursuant to this Section 5.05 to the extent that such Applied Loss Amounts have not been paid to such certificates as a Deferred Amount, any additional Subsequent Recoveries with respect to the Mortgage Loans will be applied to increase the Certificate Principal Balance of the Subordinate Certificates, beginning with the Class of Subordinate Certificates with the next highest payment priority, up to the amount of such Realized Losses previously allocated to such Class of Certificates pursuant to this Section 5.05 but only to the extent that any such Applied Loss Amount has not been paid to any Class of Certificates as a Deferred Amount. Holders of such Certificates will not be entitled to any payment in respect of current interest on the amount of such increases for any Accrual Period preceding the Distribution Date on which such increase occurs. Any such increases shall be applied to the Certificate Principal Balance of each Class III-

A-2, Class IV-A-2, Class V-A-4 or each Subordinate Certificate of such Class in accordance with its respective Percentage Interest.

(e) The REMIC I Marker Allocation Percentage of all Realized Losses on the Mortgage Loans shall be allocated on each Distribution Date to the following REMIC I Regular Interests in the specified percentages, as follows: first, to Uncertificated Accrued Interest payable to the REMIC I Regular Interest LTI-AA and REMIC I Regular Interest LTI-ZZ up to an aggregate amount equal to the REMIC I Interest Loss Allocation Amount, 98% and 2%, respectively; second, to the Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest LTI-M5 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest LTI-M5 has been reduced to zero; third, to the Uncertificated Principal Balances of the REMIC I Regular Interest LTI-AA and REMIC I Regular Interest LTI-ZZ up to an aggregate amount equal to the REMIC I Principal Loss Allocation Amount, 98% and 2%, respectively; fourth, to the Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest LTI-M4 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest LTI-M4 has been reduced to zero; fifth, to the Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest LTI-M3 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest LTI-M3 has been reduced to zero; sixth, to the Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest LTI-M2 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest LTI-M2 has been reduced to zero; seventh, to the Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest LTI-M1 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest LTI-M1 has been reduced to zero; eighth, with respect to Realized Losses on the Group III Mortgage Loans only, to the Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest LTI-IIIA2 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest LTI-IIIA2 has been reduced to zero; ninth, with respect to Realized Losses on the Group IV Mortgage Loans only, to the Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest LTI-IVA2 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest LTI-IVA2 has been reduced to zero; and tenth, with respect to Realized Losses on the Group V Mortgage Loans only, to the Uncertificated Principal Balances of REMIC I Regular Interest LTI-AA, REMIC I Regular Interest LTI-VA4 and REMIC I Regular Interest LTI-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest LTI-VA4 has been reduced to zero.

The REMIC I Sub WAC Allocation Percentage of all Realized Losses on the Mortgage Loans shall be applied after all distributions have been made on each Distribution Date first, so as to keep the Uncertificated Principal Balance of each REMIC I Regular Interest ending with the designation “GRP” equal to 0.01% of the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group; second, to each REMIC I Regular Interest ending with the designation “SUB,” so that the Uncertificated Balance of each such REMIC I Regular Interest is equal to 0.01% of the excess of (x) the aggregate Stated Principal Balance of the Mortgage

Loans in the related Loan Group over (y) the current Certificate Principal Balance of the Senior Certificate in the related Loan Group (except that if any such excess is a larger number than in the preceding distribution period, the least amount of Realized Losses shall be applied to such REMIC I Regular Interests such that the REMIC I Subordinated Balance Ratio is maintained); and third, any remaining Realized Losses shall be allocated to REMIC I Regular Interest LTI-XX.

(iv) fourth, to the Holders of REMIC I Regular Interests, in an amount equal to the remainder of the REMIC I Sub WAC Allocation Percentage of the Interest Remittance Amount and the Principal Payment Amount for such Distribution Date after the distributions made pursuant to clause (iii) above, such that distributions of principal shall be deemed to be made to the REMIC I Regular Interests first, so as to keep the Uncertificated Principal Balance of each REMIC I Regular Interest ending with the designation “GRP” equal to 0.01% of the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group; second, to each REMIC I Regular Interest ending with the designation “SUB,” so that the Uncertificated Principal Balance of each

such REMIC I Regular Interest is equal to 0.01% of the excess of (x) the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group over (y) the current Certificate Principal Balance of the Senior Certificates in the related Loan Group (except that if any such excess is a larger number than in the preceding distribution period, the least amount of principal shall be distributed to such REMIC I Regular Interests such that the REMIC I Subordinated Balance Ratio is maintained); and third, any remaining principal to REMIC I Regular Interest LTI-XX.

Section 5.08

Prepayment Charges.

On each Distribution Date, all amounts representing Prepayment Charges in respect of the Mortgage Loans received during the related Prepayment Period and deposited in the Distribution Account will be withdrawn from the Distribution Account and distributed by the Securities Administrator in accordance with the Remittance Report to the Class P Certificates and shall not be available for distribution to the holders of any other Class of Certificates. The payment of such Prepayment Charges shall not reduce the Certificate Principal Balance of the Class P Certificates.

Section 5.09

Class P Certificate Account.

The Securities Administrator shall establish and maintain with itself a separate, segregated trust account titled “HSBC Bank USA, National Association, for the benefit of Nomura Asset Acceptance Corporation, Alternative Loan Trust 2005-AR4 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 July 2010 Distribution Date, 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 5.10

Basis Risk Shortfall Reserve Fund.

(a) The Securities Administrator shall establish a Basis Risk Shortfall Reserve Fund on behalf of the holders of the Publicly Offered Certificates (other than the Group I, Group II, Group III and Group IV Certificates). The Basic Risk Shortfall Reserve Fund must be an Eligible Account. The Basis Risk Shortfall Reserve Fund shall be entitled “Basis Risk Shortfall Reserve Fund, HSBC Bank USA, National Association, as Trustee for the benefit of holders of Nomura Asset Acceptance Corporation, Mortgage Pass-Through Certificates, Series 2005-AR4, Class V-A-1, Class V-A-2, Class V-A-3, Class V-A-4, Class M-1, Class M-2, Class M-3, Class M-4 and Class M-5”. Any payments received by the Securities Administrator under the Cap Contracts shall be deposited into the Basis Risk Shortfall Reserve Fund for the benefit of the Class V-A-1, Class V-A-2 or Class V-A-3 Certificates, as applicable; provided that the amount of any Excess Cap Payments shall be held for the benefit of the Class X Certificates and payable as part of the Class X Distribution Amount for the related Distribution Date. On each Distribution Date as to which there is a Basis Risk Shortfall payable to any Class of Certificates, the Securities Administrator shall deposit the amounts pursuant to paragraphs 8, 9, 10, 11, 12 and 13 of Section 5.04(a)(iii) into the Basis Risk Shortfall Reserve Fund and the Securities Administrator has been directed by the Class X Certificateholder to distribute such amounts to the Holders of

the Publicly Offered Certificates (other than the Group I, Group II, Group III and Group IV Certificates) in the amounts and priorities set forth in Section 5.04(a)(iii).

(b) The Basis Risk Shortfall Reserve Fund is an “outside reserve fund” within the meaning of Treasury Regulation §1.860G-2(h) and shall be an asset of the Trust Fund but not an asset of any REMIC. The Securities Administrator on behalf of the Trust shall be the nominal owner of the Basis Risk Shortfall Reserve Fund. The Class X Certificateholders shall be the beneficial owners of the Basis Risk Shortfall Reserve Fund, subject to the power of the Trustee to transfer amounts under Section 5.04(a)(iii). Amounts in the Basis Risk Shortfall Reserve Fund shall be held either uninvested in a trust or deposit account of the Securities Administrator with no liability for interest or other compensation thereof or, at the written direction of the Majority Class X Certificateholder, be invested in Permitted Investments that mature no later than the Business Day prior to the next succeeding Distribution Date. All net income and gain from such investments shall be distributed to the Majority Class X Certificateholder, not as a distribution in respect of any interest in any REMIC, on such Distribution Date. All amounts earned on amounts on deposit in the Basis Risk Shortfall Reserve Fund shall be taxable to the Majority Class X Certificateholder. Any losses on such investments shall be deposited in the Basis Risk Shortfall Reserve Fund by the Majority Class X Certificateholder out of its own funds immediately as realized. In the event that the Majority Class X Certificateholder shall fail to provide investment instructions to the Securities Administrator, the amounts on deposit in the Basis Risk Shortfall Reserve Fund shall be held uninvested.

(c) For federal tax return and information reporting, the value of the right of the holders of the Class V-A-1, Class V-A-2 and Class V-A-3 Certificates to receive payments from the Basis Risk Shortfall Reserve Fund in respect of any Basis Risk Shortfall shall be $5,760.00, $2,100.00 and $1,500.00, respectively. The value of such right with respect to the Publicly Offered Certificates (other than the Class V-A-4 Certificates and the Group I, Group II, Group III and Group IV Certificates) shall be zero.

Upon original issue, the Certificates shall be executed and authenticated by the Securities Administrator and delivered by the Trustee to and upon the written order of the Depositor. The Certificates shall be executed by manual or facsimile signature on behalf of the Trust by the Securities Administrator by an authorized signatory. Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Securities Administrator shall bind the Trust, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates. No Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided herein executed by the Securities Administrator by manual signature, and such certificate of authentication shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication.

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.

(b) The Class X Certificates and Class P Certificates offered and sold to Qualified Institutional Buyers in reliance on Rule 144A under the Securities Act (“Rule 144A”) will be issued in the form of Definitive Certificates.

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 Certificates 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 Securities Administrator. 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 a 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”) 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 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.

No Transfer of an ERISA Restricted Certificate shall be made unless the Securities Administrator shall have received either (i) a representation from the transferee of such Certificate acceptable to and in form and substance satisfactory to the Securities Administrator to the effect that such transferee is not an employee benefit plan subject to Section 406 of ERISA and/or a plan subject to Section 4975 of the Code, or a Person acting on behalf of any such plan or using the assets of any such plan, or (ii) in the case of any such ERISA Restricted Certificate presented for registration in the name of an employee benefit plan subject to ERISA, or a plan subject to Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a trustee of any such plan or any other person acting on behalf of any such plan, an Opinion of Counsel satisfactory to the Securities Administrator for the benefit of the Securities Administrator, the Depositor and the Servicer and on which they may rely to the effect that the purchase and holding of such ERISA Restricted Certificate is permissible under applicable law, will not result in any prohibited transactions under ERISA or Section 4975 of the Code and will not subject the Securities Administrator, the Depositor or any Servicer to any obligation in addition to those expressly undertaken in this Agreement, which Opinion of Counsel shall not be an expense of the Securities Administrator, the Depositor or any Servicer. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA Restricted Certificate to or on behalf of an employee benefit plan subject to Section 406 of ERISA and/or a plan subject to Section 4975 of the Code other than in compliance with the foregoing shall be void and of no effect; provided that the restriction set forth in this sentence shall not be applicable if there has been delivered to the Securities Administrator an Opinion of Counsel meeting the requirements of clause (ii) of the first sentence of this paragraph. The Securities Administrator shall not be under any liability to any Person for any registration of transfer of any ERISA Restricted 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. The Securities Administrator shall be entitled, but not obligated, to recover from any Holder of any ERISA Restricted Certificate that was in fact an employee benefit plan subject to Section 406 of ERISA or a plan subject to Section 4975 of the Code or a Person acting on behalf of any such plan at the time it became a Holder or, at such subsequent time as it became such a plan or Person acting on behalf of such a plan, all payments

made on such ERISA Restricted 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 Holder of such Certificate that is not such a plan or Person acting on behalf of a plan.

Each beneficial owner of a Class M-1, Class M-2 or Class M-3 Certificate or any interest therein shall be deemed to have represented, by virtue of its acquisition or holding of that certificate or interest therein, that either (i) it is not a Plan or investing with “Plan Assets”, (ii) it has acquired and is holding such certificate in reliance on the Exemption, and that it understands that there are certain conditions to the availability of the Exemption, including that the certificate must be rated, at the time of purchase, not lower than “BBB-“ (or its equivalent) by S&P or Moody’s, and the certificate is so rated or (iii) (1) it is an insurance company, (2) the source of funds used to acquire or hold the certificate or interest therein is an “insurance company general account,” as such term is defined in Prohibited Transaction Class Exemption (“PTCE”) 95-60 and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

(c) (i) 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:

(A) 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.

(B) In connection with any proposed Transfer of any Ownership Interest in a Residual Certificate, the Trustee shall require delivery to it, and shall not register the Transfer of any Residual Certificate until its receipt of, an affidavit and agreement (a “Transfer Affidavit and Agreement,” in the form attached hereto as Exhibit B-3) from the proposed Transferee, in form and substance satisfactory to the Securities Administrator, representing and warranting, among other things, that such Transferee is a Permitted Transferee, that it is not acquiring its Ownership Interest in the Residual Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person that is not a Permitted Transferee, that for so long as it retains its Ownership Interest in a Residual Certificate, it will endeavor to remain a Permitted Transferee, and that it has reviewed the provisions of this Section 6.02(d) and agrees to be bound by them.

(C) Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed Transferee under clause (B) above, if an authorized officer of the Securities Administrator who is assigned to this transaction has actual knowledge that the proposed Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest in a Residual Certificate to such proposed Transferee shall be effected.

(D) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (x) to require a Transfer Affidavit and Agreement from any other Person to whom such Person attempts to transfer its Ownership Interest in a Residual Certificate and (Y) not to transfer its Ownership Interest unless it provides a Transferor Affidavit (in the form attached hereto as Exhibit B-2) to the Securities Administrator stating that, among other things, it has no actual knowledge that such other Person is not a Permitted Transferee.

(E) Each Person holding or acquiring an Ownership Interest in a Residual Certificate, by purchasing an Ownership Interest in such Certificate, agrees to give the Securities Administrator written notice that it is a “pass-through interest holder” within the meaning of temporary Treasury regulation Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership Interest in a Residual Certificate, if it is, or is holding an Ownership Interest in a Residual Certificate on behalf of, a “pass-through interest holder.”

(ii) The Securities Administrator will register the Transfer of any Residual Certificate only if it shall have received the Transfer Affidavit and Agreement and all of such other documents as shall have been reasonably required by the Securities Administrator as a condition to such registration. In addition, no Transfer of a Residual Certificate shall be made unless the Securities Administrator shall have received a representation letter from the Transferee of such Certificate to the effect that such Transferee is a Permitted Transferee.

(iii) (A) If any purported Transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 6.02(d), then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights as holder thereof retroactive to the date of registration of such Transfer of such Residual Certificate. The Securities Administrator shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by this Section 6.02(d) or for making any payments due on such Certificate to the holder thereof or for taking any other action with respect to such holder under the provisions of this Agreement.

(B) If any purported Transferee shall become a holder of a Residual Certificate in violation of the restrictions in this Section 6.02(d) and to the extent that the retroactive restoration of the rights of the holder of such Residual Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Securities Administrator shall have the right, without notice to the holder or any prior holder of such Residual Certificate, to sell such Residual Certificate to a purchaser selected by the Securities Administrator on such terms as the Securities Administrator may choose. Such purported Transferee shall promptly endorse and deliver each Residual Certificate in accordance with the instructions of the Securities Administrator. Such purchaser may be the Securities Administrator itself or any Affiliate of the Securities Administrator. The proceeds of such sale, net of the commissions (which may include commissions payable to the Securities Administrator or its Affiliates), expenses and taxes due, if any, will be remitted by the Securities Administrator to

such purported Transferee. The terms and conditions of any sale under this clause (iii)(B) shall be determined in the sole discretion of the Securities Administrator, and the Securities Administrator shall not be liable to any Person having an Ownership Interest in a Residual Certificate as a result of its exercise of such discretion.

(iv) The Securities Administrator shall make available to the Internal Revenue Service and those Persons specified by the REMIC Provisions all information necessary to compute any tax imposed (A) as a result of the Transfer of an Ownership Interest in a Residual Certificate to any Person who is a Disqualified Organization, including the information described in Treasury regulations sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the “excess inclusions” of such Residual Certificate and (B) as a result of any regulated investment company, real estate investment trust, common trust fund, partnership, trust, estate or organization described in Section 1381 of the Code that holds an Ownership Interest in a Residual Certificate having as among its record holders at any time any Person which is a Disqualified Organization. Reasonable compensation for providing such information may be charged or collected by the Securities Administrator.

(v) The provisions of this Section 6.02(d) set forth prior to this subsection (v) may be modified, added to or eliminated, provided that there shall have been delivered to the Securities Administrator at the expense of the party seeking to modify, add to or eliminate any such provision the following:

(A) written notification from each Rating Agency to the effect that the modification, addition to or elimination of such provisions will not cause such Rating Agency to downgrade its then-current ratings of any Class of Certificates; and

(B) an Opinion of Counsel, in form and substance satisfactory to the Securities Administrator, to the effect that such modification of, addition to or elimination of such provisions will not cause any Trust REMIC to cease to qualify as a REMIC and will not cause any Trust REMIC, as the case may be, to be subject to an entity-level tax caused by the Transfer of any Residual Certificate to a Person that is not a Permitted Transferee or a Person other than the prospective transferee to be subject to a REMIC-tax caused by the Transfer of a Residual Certificate to a Person that is not a Permitted Transferee.

(d) Subject to the preceding subsections, upon surrender for registration of transfer of any Certificate at any office or agency of the Securities Administrator maintained for such purpose pursuant to Section 9.11, the Securities Administrator shall execute, authenticate and deliver, in the name of the designated Transferee or Transferees, one or more new Certificates of the same Class of a like aggregate Percentage Interest.

(e) At the option of the Holder thereof, any Certificate may be exchanged for other Certificates of the same Class with authorized denominations and a like aggregate Percentage Interest, upon surrender of such Certificate to be exchanged at any office or agency of the Securities Administrator maintained for such purpose pursuant to Section 9.11. Whenever any

Certificates are so surrendered for exchange, the Securities Administrator shall execute, authenticate and deliver, the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for transfer or exchange shall (if so required by the Securities Administrator) be duly endorsed by, or be accompanied by a written instrument of transfer in the form satisfactory to the Securities Administrator duly executed by, the Holder thereof or his attorney duly authorized in writing. In addition, with respect to each Class R Certificate, the holder thereof may exchange, in the manner described above, such Class R Certificate for three separate certificates, each representing such holder’s respective Percentage Interest in the Class R-I Interest and the Class R-II Interest, respectively, in each case that was evidenced by the Class R Certificate being exchanged.

(f) No service charge to the Certificateholders shall be made for any transfer or exchange of Certificates, but the Securities Administrator may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

(g) 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 Securities Administrator, the Depositor or the Seller.

(h) All Certificates surrendered for transfer and exchange shall be canceled and destroyed by the Securities Administrator in accordance with its customary procedures.

Section 6.03

Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Securities Administrator, or the Securities Administrator 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 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 Depositor, the Servicer, the Trustee, the Master Servicer, the Securities Administrator and any of their agents 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 none of the Depositor, the Servicer, the Trustee, the Master Servicer, the Securities Administrator nor any of their agents 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 Regular 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 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 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 Depositor, the Servicer, the Trustee, the Master Servicer and the Securities Administrator 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.

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, at its sole option, 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 either of the events described in clauses (a) or (b) above, Certificate Owners of such Book-Entry Certificates having not less than fifty one percent (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, then the Securities Administrator 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.

Each of the Master Servicer and the Servicer shall afford (and any Sub-Servicing Agreement shall provide that each Sub-Servicer 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 Sub-Servicer) 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 Sub-Servicer) responsible for such obligations, and the Master Servicer shall have access to all such records maintained by the Servicer and any Sub-Servicers.

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 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.

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 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 such Servicer’s sole expense.

The Master Servicer shall not have knowledge of a Servicer Default unless a Responsible Officer of the Master Servicer has actual knowledge or unless written notice of any Servicer Default is received by the Master Servicer at its address for notice and such notice references the Certificates, the Trust Fund or this Agreement.

On or after 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 Certificates (other than as a Holder of any Certificate) or the Mortgage Loans or otherwise including, without limitation, the compensation payable to the Master Servicer under this Agreement, shall pass to and be vested in the Trustee pursuant to and under this Section, and, without limitation, the Trustee is hereby authorized and empowered, as attorney-in-fact or otherwise, to execute and deliver, on behalf of and at the expense of the Master Servicer, any and all documents and other instruments and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise.

Section 8.02

Master Servicer to Act; Appointment of Successor.

On and after the time the Servicer receives a notice of termination pursuant to Section 8.01, the Master Servicer shall become the successor to such 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 will make any Advance required to be made by the terminated Servicer on the Distribution Date on which the terminated 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 VI of this Agreement 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 Fannie Mae 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 the 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 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 terminated 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 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 the 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 the Successor Servicer to service the related 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 3.32. 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

Notification to Certificateholders.

(a) Upon any termination of or appointment of a successor to the Servicer or the Master Servicer, the Trustee 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 Trustee shall transmit by mail to all Certificateholders notice of each such Servicer Default or Master Servicer Default hereunder known to the Trustee, unless such default shall have been cured or waived.

Section 8.04

Waiver of Servicer Defaults and Master Servicer Defaults.

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 Master Servicer 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 Servicer Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived in writing.

If any such instrument is found not to conform to the requirements of this Agreement in a material manner, the Trustee or the Securities Administrator, as the case may be, shall take such action as it deems appropriate to have the instrument corrected, and if the instrument is not corrected to its satisfaction, the Securities Administrator will provide notice to the Trustee thereof and the Trustee will provide notice to the Certificateholders.

(c) The Trustee shall promptly remit to the Servicer any complaint, claim, demand, notice or other document (collectively, the “Notices”) delivered to the Trustee as a consequence of the assignment of any Mortgage Loan hereunder and relating to the servicing of the Mortgage Loans; provided than any such notice (i) is delivered to the Trustee at its Corporate Trust Office, (ii) contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property. The Trustee shall have no duty hereunder with respect to any Notice it may receive or which may be alleged to have been delivered to or served upon it unless such Notice is delivered to it or served upon it at its Corporate Trust Office and such Notice contains the information required pursuant to clause (ii) of the preceding sentence.

(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 misconduct; provided, however, that:

(i) Prior to the occurrence of a Master Servicer Default and after the curing or waiver of all such Master Servicer Defaults which may have occurred with respect to the Trustee and at all times with respect to the Securities Administrator, the duties and obligations of the Trustee and the Securities Administrator shall be determined solely by the express provisions of this Agreement, neither the Trustee nor the Securities Administrator shall be liable except for the performance of its duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be

read into this Agreement against the Trustee or the Securities Administrator and, in the absence of bad faith on the part of the Trustee or the Securities Administrator, respectively, the Trustee or the Securities Administrator, respectively, 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, respectively, that conform 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 an officer or officers of the Securities Administrator, respectively, unless it shall be proved that the Trustee or Securities Administrator, respectively, 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) The Trustee shall not be required to take notice or be deemed to have notice or knowledge of any default or Master Servicer Default unless a Responsible Officer of the Trustee shall have actual knowledge thereof. In the absence of such notice, the Trustee may conclusively assume there is no such default or Master Servicer Default;

(v) The Trustee shall not in any way be liable by reason of any insufficiency in any Account held by or in the name of Trustee unless it is determined by a court of competent jurisdiction that the Trustee’s gross negligence or willful misconduct was the primary cause of such insufficiency (except to the extent that the Trustee 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 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 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 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 or use under the circumstances in the conduct of his own affairs;

The Trustee and the Securities Administrator may at any time resign (including, without limitation, and in the case of the Securities Administrator, upon the resignation or removal of the Master Servicer) and be discharged from the trust hereby created by giving written notice thereof to the Depositor, to the Master Servicer, to the Securities Administrator (or the Trustee, if the Securities Administrator resigns) and to the Certificateholders. Upon receiving such notice of resignation, the Depositor shall promptly appoint a successor trustee or successor securities administrator by written instrument, in duplicate, which instrument shall be delivered to the resigning Trustee or Securities Administrator, as applicable, and to the successor trustee or successor securities administrator, as applicable. A copy of such instrument shall be delivered to the Certificateholders, the Trustee, the Securities Administrator and the Master Servicer by the Depositor.

A copy of such instrument shall be delivered to the Certificateholders, the Trustee, the Securities Administrator and the Master Servicer by the Depositor.

The Holders of Certificates entitled to at least 51% of the Voting Rights may at any time remove the Trustee or the Securities Administrator and appoint a successor trustee or successor securities administrator by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered to the Depositor, one complete set to the Trustee or the Securities Administrator so removed and one complete set to the successor so appointed.

Administrator), the Securities Administrator (in the case of the removal of the Trustee) and the Master Servicer by the Depositor.

Any resignation or removal of the Trustee or the Securities Administrator and appointment of a successor trustee or successor securities administrator pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor trustee or successor securities administrator, as applicable, as provided in Section 9.08.

Notwithstanding anything to the contrary contained herein, the Master Servicer and the Securities Administrator shall at all times be the same Person.

Section 9.08

Successor Trustee or Securities Administrator.

Any successor trustee or successor securities administrator appointed as provided in Section 9.07 hereof shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee or predecessor securities administrator instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee or predecessor securities administrator shall become effective and such successor trustee or successor securities administrator, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee or Securities Administrator herein. The predecessor trustee or predecessor securities administrator shall deliver to the successor trustee or successor securities administrator all Mortgage Loan Documents and related documents and statements to the extent held by it hereunder, as well as all monies, held by it hereunder, and the Depositor and the predecessor trustee or predecessor securities administrator shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee or successor securities administrator all such rights, powers, duties and obligations.

No successor trustee or successor securities administrator shall accept appointment as provided in this Section 9.08 unless at the time of such acceptance such successor trustee or successor securities administrator shall be eligible under the provisions of Section 9.07 hereof and its appointment shall not adversely affect the then current rating of the Certificates.

Upon acceptance of appointment by a successor trustee or successor securities administrator as provided in this Section 9.08, the successor trustee or successor securities administrator shall mail notice of the succession of such trustee or securities administrator hereunder to all Holders of Certificates.

the corporate trust business of the Trustee or Securities Administrator or shall be the successor of the Trustee or Securities Administrator hereunder, provided that such corporation shall be eligible under the provisions of Section 9.06 without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 9.10

Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the REMIC I or property securing the same may at the time be located, the Trustee shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of REMIC I, and to vest in such Person or Persons, in such capacity, and for the benefit of the Holders of the Certificates, such title to REMIC I, or any part thereof, and, subject to the other provisions of this Section 9.10, such powers, duties, obligations, rights and trusts as the Trustee may consider necessary or desirable. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 9.06 hereunder and no notice to Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 9.08 hereof.

In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 9.10 all rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed by the Trustee (whether as Trustee hereunder or as successor to a defaulting Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to REMIC I or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee.

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

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

(ii) The execution and delivery of this Agreement by it, and the performance and compliance with the terms of this Agreement by it, will not violate its articles of association or bylaws or constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, or result in the breach of, any material agreement or other instrument to which it is a party or which is applicable to it or any of its assets.

(iii) It has the full power and authority to enter into and consummate all transactions contemplated by this Agreement, has duly authorized the execution, delivery and performance of this Agreement, and has duly executed and delivered this Agreement.

(v) It is not in violation of, and its execution and delivery of this Agreement and its performance and compliance with the terms of this Agreement will not constitute a violation of, any law, any order or decree of any court or arbiter, or any order, regulation or demand of any federal, state or local governmental or regulatory authority, which violation, in its good faith and reasonable judgment, is likely to affect materially and adversely either the ability of it to perform its obligations under this Agreement or its financial condition.

No litigation is pending or, to the best of its knowledge, threatened against it, which would prohibit it from entering into this Agreement or, in its good faith reasonable judgment, is likely to materially and adversely affect either the ability of it to perform its obligations under this Agreement or its financial condition.

Section 9.13

Tax Matters.

It is intended that the Trust Fund shall constitute, and that the affairs of the Trust Fund shall be conducted so that each REMIC formed hereunder qualifies as, a “real estate mortgage investment conduit” as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Securities Administrator covenants and agrees that it shall act as agent (and the Securities Administrator is hereby appointed to act as agent) on behalf of the Trust Fund. The Securities Administrator, as agent on behalf of the Trust Fund, shall do or refrain from doing, as applicable, the following: (a) the Securities Administrator shall prepare and file, or cause to be prepared and filed, in a timely manner, U.S. Real Estate Mortgage Investment Conduit Income Tax Returns (Form 1066 or any successor form adopted by the Internal Revenue Service) and prepare and file or cause to be prepared and filed with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to each such REMIC containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish or cause to be furnished to Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby; (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 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; (g) the Securities Administrator shall not knowingly or intentionally take any action or omit to take any action that would cause the termination of the REMIC status of any REMIC formed hereunder; (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 or cause to be signed federal, state or local income tax or information returns or any other document prepared by the Securities Administrator pursuant to this Section 9.13 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) the Securities Administrator shall not 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 Securities Administrator 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 of REMIC I or REMIC II 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 of REMIC I or REMIC II 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 of REMIC I or REMIC II, 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 Class R Certificateholders, and second with amounts otherwise to be distributed to all other Certificateholders in the following order of priority: first, to the Class M-5 Certificates, second, to the Class M-4 Certificates, third, to the Class M-3 Certificates, fourth, to the Class M-2 Certificates, fifth, to the Class M-1 Certificates, and sixth, 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 Class R 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 monthly report to Certificateholders 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. Notwithstanding the foregoing, however, in no event shall the Securities Administrator have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of this Agreement, (2) for any losses other than arising out of a grossly negligent performance by the Securities Administrator of its duties and obligations set forth herein, and (3) for any special or consequential damages to Certificateholders (in addition to payment of principal and interest on the Certificates).

ARTICLE X

TERMINATION

Section 10.01

Termination upon Liquidation or Repurchase of all Mortgage Loans.

Subject to Section 10.03, the obligations and responsibilities of the Depositor, the Seller, the Securities Administrator, the Master Servicer and the Trustee created hereby with respect to the Trust Fund shall terminate (other than the obligations of the Master Servicer to the Trustee pursuant to Section 9.05 and of the Securities Administrator to make payments in respect of the REMIC I Regular Interests or the Classes of Certificates as hereinafter set forth) upon the earlier of (a) the Master Servicer’s exercise of its optional right to purchase the Mortgage Loans and related REO Properties (the “Clean-up Call”) and (b) the later of (i) the maturity or other liquidation (or any Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property and (ii) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement, as applicable. In no event shall the trusts created hereby continue beyond the earlier of (i) the expiration of twenty-one (21) years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof and (ii) the Latest Possible Maturity Date.

The Cleanup Call shall be exercisable at a price (the “Termination Price”) equal to the sum of (i) 100% of the Stated Principal Balance of Mortgage Loan, (ii) accrued interest thereon at the applicable Mortgage Rate to, but not including, the first day of the month of such purchase, (iii) the appraised value of any related REO Property (up to the Stated Principal Balance of the related Mortgage Loan), such appraisal to be conducted by an appraiser mutually agreed upon by the Master Servicer and the Trustee, (iv) unreimbursed out-of-pocket costs of the Securities Administrator, the Master Servicer, the Servicer or the Trustee, including unreimbursed servicing advances and the principal portion of any unreimbursed Advances, made on the related Mortgage Loans prior to the exercise of such repurchase right and (v) any other amounts due and owing to the Trustee, the Securities Administrator, the Master Servicer and the Custodians payable pursuant to this Agreement or the Custodial Agreements.

The right to exercise the Cleanup Call pursuant to the preceding paragraph shall be exercisable if the Stated Principal Balance of all of the Mortgage Loans at the time of any such repurchase, is less than or equal to ten percent (10%) of the aggregate Cut-off Date Principal Balance of the Mortgage Loans.

Section 10.02

Final Distribution on the Certificates.

If on any Determination Date, (i) the Securities Administrator determines based on the reports delivered by the Master Servicer under this Agreement that there are no Outstanding Mortgage Loans, and no other funds or assets in the Trust Fund other than the funds in the Distribution Account, the Securities Administrator shall notify the Trustee and send a final distribution notice promptly to each related Certificateholder or (ii) the Securities Administrator determines that a Class of Certificates shall be retired after a final distribution on such Class, the Securities Administrator shall notify the Trustee and the Certificateholders within five (5) Business Days after such Determination Date that the final distribution in retirement of such

Class of Certificates is scheduled to be made on the immediately following Distribution Date. Any final distribution made pursuant to the immediately preceding sentence will be made only upon presentation and surrender of the related Certificates at the office of the Securities Administrator set forth herein. If the Master Servicer elects to terminate the Trust Fund pursuant to Section 10.01, at least twenty (20) days prior to the date notice is to be mailed to the Certificateholders, the Master Servicer shall notify the Securities Administrator and the Trustee of the date the Master Servicer intends to terminate the Trust Fund. The Master Servicer shall remit the Termination Price to the Securities Administrator on behalf of the Trust Fund on the Business Day prior to the Distribution Date for such Optional Termination by the Master Servicer.

Notice of the exercise of the Cleanup Call, specifying the Distribution Date on which the Certificateholders may surrender their Certificates for payment of the final distribution and cancellation, shall be given promptly by the Securities Administrator by letter to the Certificateholders mailed no later than the fifteenth (15th) day of the month of such final distribution. Any such notice shall specify (a) the Distribution Date upon which final distribution on the Certificates will be made upon presentation and surrender of the Certificates at the office therein designated, (b) the amount of such final distribution, (c) the location of the office or agency at which such presentation and surrender must be made and (d) that the Record Date otherwise applicable to such Distribution Date is not applicable, distributions being made only upon presentation and surrender of the Certificates at the office therein specified. The Securities Administrator will give such notice to each Rating Agency at the time such notice is given to the Certificateholders.

In the event such notice is given, the Master Servicer shall deposit in the Distribution Account on the Business Day prior to the applicable Distribution Date in an amount equal to the final distribution in respect of the Certificates. Upon certification to the Trustee by the Securities Administrator of the making of such final deposit, the Trustee shall promptly release or cause to be released to the Master Servicer the Mortgage Files for the remaining Mortgage Loans, and the Trustee shall execute all assignments, endorsements and other instruments delivered to it and necessary to effectuate such transfer.

Upon presentation and surrender of the related Certificates, the Securities Administrator shall cause to be distributed to Certificateholders of each Class the amounts allocable to such Certificates held in the Distribution Account in the order and priority set forth in Section 5.04 hereof on the final Distribution Date and in proportion to their respective Percentage Interests.

In the event that any affected Certificateholders shall not surrender Certificates for cancellation within six (6) months after the date specified in the above mentioned written notice, the Securities Administrator shall give a second written notice to the remaining affected Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six (6) months after the second notice all the applicable Certificates shall not have been surrendered for cancellation, the Securities Administrator may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining affected Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets that remain a part of the Trust Fund. If within two (2) years after the second notice all affected Certificates shall not have been surrendered for cancellation, the related Residual Certificateholders shall be entitled to all

unclaimed funds and other assets of the Trust Fund that remain subject hereto and the Securities Administrator shall release such funds upon written direction.

Section 10.03

Additional Termination Requirements.

In the event of (i) the exercise by the Master Servicer of the Cleanup Call pursuant to the terms of this Agreement, or (ii) the final payment on or other liquidation of the last Mortgage Loan or REO Property in REMIC I pursuant to Section 10.01, the following additional requirements, unless the Trustee has been supplied with an Opinion of Counsel, at the expense of the Master Servicer (in the case of the exercise of the Cleanup Call) or the Depositor, to the effect that the failure of the Trust Fund to comply with the requirements of this Section 10.03 will not (i) result in the imposition of taxes on “prohibited transactions” of a REMIC, or (ii) cause any REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(1)	The Master Servicer (in the case of the exercise of the Cleanup Call) or the Depositor (in all other cases) shall establish a ninety-day liquidation period and notify the Trustee thereof, and the Trustee shall in turn specify the first day of such period in a statement attached to the tax return for each of REMIC I and REMIC II pursuant to Treasury Regulation Section 1.860F-1. The Master Servicer or the Depositor, as applicable, shall satisfy all the requirements of a qualified liquidation under Section 860F of the Code and any regulations thereunder, as evidenced by an Opinion of Counsel obtained at the expense of the Master Servicer or the Depositor, as applicable;

(2)	During such ninety-day liquidation period, and at or prior to the time of making the final payment on the Certificates, the Master Servicer (in the case of the exercise of the Cleanup Call) or the Depositor (in all other cases) shall sell all of the assets of REMIC I for cash; and

(3)	At the time of the making of the final payment on the Certificates, the Trustee shall distribute or credit, or cause to be distributed or credited, to the Holders of the related Residual Certificates all cash on hand in the Trust Fund (other than cash retained to meet claims), and the Trust Fund shall terminate at that time.

By their acceptance of the Certificates, the Holders thereof hereby authorize the Master Servicer (in the case of the exercise of the Cleanup Call) or the Depositor (in all other cases) to specify the ninety-day liquidation period for REMIC I and REMIC II, which authorization shall be binding upon all successor Certificateholders.

The Trustee as agent for each REMIC hereby agrees to adopt and sign such a plan of complete liquidation upon the written request of the Master Servicer or the Depositor, as applicable, and the receipt of the Opinion of Counsel referred to in Section 10.03(1) and to take such other action in connection therewith as may be reasonably requested by the Master Servicer or the Depositor, as applicable.

ARTICLE XI

MISCELLANEOUS PROVISIONS

Section 11.01

Amendment.

This Agreement may be amended from time to time by parties hereto, without the consent of any of the Certificateholders to cure any ambiguity, to correct or supplement any provisions herein, to change the manner in which the Distribution Account maintained by the Securities Administrator or the Custodial Account maintained by the Servicer is maintained or to make such other provisions with respect to matters or questions arising under this Agreement as shall not be inconsistent with any other provisions herein if such action shall not, as evidenced by an Opinion of Counsel, adversely affect in any material respect the interests of any Certificateholder; provided that any such amendment shall be deemed not to adversely affect in any material respect the interests of the Certificateholders and no such Opinion of Counsel shall be required if the Person requesting such amendment obtains a letter from each Rating Agency stating that such amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates.

Notwithstanding the foregoing, without the consent of the Certificateholders, the parties hereto may at any time and from time to time amend this Agreement to modify, eliminate or add to any of its provisions to such extent as shall be necessary or appropriate to maintain the qualification of each of REMIC I and REMIC II as a REMIC under the Code or to avoid or minimize the risk of the imposition of any tax on any of REMIC I or REMIC II pursuant to the Code that would be a claim against any of REMIC I or REMIC II at any time prior to the final redemption of the Certificates, provided that the Trustee has been provided an Opinion of Counsel, which opinion shall be an expense of the party requesting such opinion but in any case shall not be an expense of the Trustee or the Trust Fund, to the effect that such action is necessary or appropriate to maintain such qualification or to avoid or minimize the risk of the imposition of such a tax.

This Agreement may also be amended from time to time by the parties hereto and the Holders of each Class of Certificates affected thereby evidencing over 50% of the Voting Rights of such Class or Classes 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 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, (ii) cause any of REMIC I or REMIC II to cease to qualify as a REMIC or (iii) reduce the aforesaid percentages of Certificates of each Class the Holders of which are required to consent to any such amendment without the consent of the Holders of all Certificates of such Class then outstanding.

Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel, which opinion shall be an expense of the party requesting such amendment but in any case shall not be an expense of the Trustee, to the effect that such amendment will not (other than an amendment pursuant to clause (ii) of, and in accordance with, the preceding paragraph) cause the imposition of any tax on REMIC I or REMIC II or the Certificateholders or cause REMIC I or

REMIC II to cease to qualify as a REMIC at any time that any Certificates are outstanding. Further, nothing in this Agreement shall require the Trustee to enter into an amendment without receiving an Opinion of Counsel, satisfactory to the Trustee that (i) such amendment is permitted and is not prohibited by this Agreement and (ii) that all requirements for amending this Agreement (including any consent of the applicable Certificateholders) have been complied with.

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

It shall not be necessary for the consent of Certificateholders under this Section 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 Trustee may prescribe.

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.

Section 11.06

No Certificateholder shall have any right to vote (except as provided herein) or in any manner otherwise control the operation and management of the Trust Fund, or the obligations of the parties hereto, nor shall anything herein set forth or contained in the terms of the Certificates be construed so as to constitute the Certificateholders from time to time as partners or members

of an association; nor shall any Certificateholder be under any liability to any third party by reason of any action taken by the parties to this Agreement pursuant to any provision hereof.

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee, a written notice of a Servicer Default and of the continuance thereof, as hereinbefore provided, the Holders of Certificates evidencing not less than twenty five percent (25%) of the Voting Rights evidenced by the Certificates shall also have made written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee, hereunder and shall have offered to the Trustee such indemnity satisfactory to it as it may require against the costs, expenses, and liabilities to be incurred therein or thereby, and the Trustee or for sixty (60) days after its receipt of such notice, request and offer of indemnity shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Agreement, except in the manner herein provided and for the common benefit of all Certificateholders.

evidencing a fractional undivided interest in the distributions allocable to the Class [I][II][III][IV]-A-[1][2] Certificates with respect to a Trust Fund consisting primarily of a pool of conventional one- to four-family adjustable rate mortgage loans sold by NOMURA ASSET ACCEPTANCE CORPORATION

This Certificate is payable solely from the assets of the Trust Fund, and does not represent an obligation of or interest in Nomura Asset Acceptance Corporation (“NAAC”) or the Trustee or any of their affiliates or any other person. Neither this Certificate nor the underlying Mortgage Loans are guaranteed or insured by any governmental entity or by NAAC or the Trustee or any of their affiliates or any other person. None of NAAC, the Trustee or any of their affiliates will have any obligation with respect to any certificate or other obligation secured by or payable from payments on the Certificates.

This certifies that Cede & Co. is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in a trust (the “Trust Fund”) generally consisting of conventional first lien, adjustable rate mortgage loans secured by one- to four- family residences, units in planned unit developments and individual condominium units (collectively, the “Mortgage Loans”) sold by NAAC. The Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the “Seller”) to NAAC. The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date specified above (the “Agreement”), among NAAC, as depositor (the “Depositor”), the Seller, GMAC Mortgage Corporation, as servicer (the “Servicer”), Wells Fargo

Bank, N.A. as master servicer (the “Master Servicer”) and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association, as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Interest on this Certificate will accrue during the calendar month prior to the calendar month in which a Distribution Date (as hereinafter defined) occurs on the Certificate Principal Balance hereof at a per annum Pass-Through Rate equal to [for Class I-A Certificates: the weighted average of the Net Mortgage Rates of the Group I Mortgage Loans] [for Class II-A Certificates: the weighted average of the Net Mortgage Rates of the Group II Mortgage Loans] [for Class III-A-1 Certificates and Class III-A-2 Certificates: the weighted average of the Net Mortgage Rates of the Group III Mortgage Loans] [for Class IV-A-1 Certificates and Class IV-A-2 Certificates: the weighted average of the Net Mortgage Rates of the Group IV Mortgage Loans]. The Securities Administrator will distribute on the 25th day of each month, or, if such 25th day is not a Business Day, the immediately following Business Day (each, a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the calendar month immediately preceding the month in which the Distribution Date occurs, an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount (of interest and principal, if any) required to be distributed to the Holders of Certificates of the same Class as this Certificate. The Assumed Final Distribution Date is the Distribution Date in the second month following the latest scheduled maturity date of any Mortgage Loan and is not likely to be the date on which the Certificate Principal Balance of this Class of Certificates will be reduced to zero.

Distributions on this Certificate will be made by the Securities Administrator by check mailed to the address of the Person entitled thereto as such name and address shall appear on the Certificate Register or, if such Person so requests by notifying the Securities Administrator in writing as specified in the Agreement. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose and designated in such notice. The initial Certificate Principal Balance of this Certificate is set forth above. The Certificate Principal Balance hereof will be reduced to the extent of distributions allocable to principal hereon [for Class III-A-2 Certificates only: and Realized Losses on the Group III Mortgage Loans allocable to the Class III-A-2 Certificates] [for Class IV-A-2 Certificates only: and Realized Losses on the Group IV Mortgage Loans allocable to the Class IV-A-2 Certificates].

This Certificate is one of a duly authorized issue of Certificates designated as set forth on the face hereof (the “Certificates”). The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the Trust Fund for payment hereunder and that the Trustee is not liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits, obligations and duties evidenced hereby, and the rights, duties and immunities of the Securities Administrator. The Certificates are limited in right of payment to certain collections and recoveries respecting the Mortgage Loans and other assets included in the Trust Fund, all as more specifically set forth in the Agreement.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor and the rights of the Certificateholders under the Agreement from time to time by the parties thereto with the consent of the Holders of the Class or Classes of Certificates affected thereby evidencing over 50% of the Voting Rights of such Class or Classes. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable with the Securities Administrator upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Securities Administrator for such purposes, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Securities Administrator duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates in authorized denominations representing a like aggregate Percentage Interest will be issued to the designated transferee.

The Certificates are issuable only as registered Certificates without coupons in the Classes and denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for one or more new Certificates evidencing the same Class and in the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

No service charge will be made to the Certificateholders for any such registration of transfer, but the Securities Administrator may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of Depositor, the Master Servicer, the Trustee, the Securities Administrator or any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby (other than the obligations to make payments to Certificateholders with respect to the termination

of the Agreement) shall terminate upon the earlier of (i) the later of (A) the maturity or other liquidation (or Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and disposition of all property acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the remittance of all funds due under the Agreement, or (ii) the optional repurchase by the party named in the Agreement of all the Mortgage Loans and other assets of the Trust Fund in accordance with the terms of the Agreement. Such optional repurchase may be made only if on such Distribution Date the aggregate Stated Principal Balance of the Mortgage Loans is less than or equal to 10% of the aggregate Stated Principal Balance of the Mortgage Loans at the Cut-off Date. The exercise of such right will effect the early retirement of the Certificates. In no event, however, will the Trust Fund created by the Agreement continue beyond the earlier to occur of (i) expiration of 21 years after the death of certain persons identified in the Agreement and (ii) the Assumed Final Distribution Date.

Unless this Certificate has been countersigned by an authorized signatory of the Securities Administrator by manual signature, this Certificate shall not be entitled to any benefit under the Agreement, or be valid for any purpose.

IN WITNESS WHEREOF, the Securities Administrator has caused this Certificate to be duly executed.

This Certificate is payable solely from the assets of the Trust Fund, and does not represent an obligation of or interest in Nomura Asset Acceptance Corporation (“NAAC”) or the Trustee referred to below or any of their affiliates or any other person. Neither this Certificate nor the underlying Mortgage Loans are guaranteed or insured by any governmental entity or by NAAC or the Trustee or any of their affiliates or any other person. None of NAAC, the Trustee or any of their affiliates will have any obligation with respect to any certificate or other obligation secured by or payable from payments on the Certificates.

This certifies that Nomura Securities International, Inc. is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in a trust (the “Trust Fund”), generally consisting of conventional first lien, adjustable rate mortgage loans secured by one- to four- family residences, units in planned unit developments and individual condominium units (collectively, the “Mortgage Loans”) sold by NAAC. The Mortgage Loans were sold by Nomura Credit & Capital, Inc. (the “Seller”) to NAAC.
