CONVEYANCE OF MORTGAGE LOANS;

ORIGINAL ISSUANCE OF CERTIFICATES

Section 2.01 Conveyance of Mortgage Loans and Other Trust Assets.

The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, assign, set over and otherwise convey in trust to the Trustee without recourse for the benefit of the Certificateholders all the right, title and interest of the Depositor, including any security interest therein for the benefit of the Depositor, in and to (i) each Mortgage Loan identified on the Mortgage Loan Schedule, including the related Cut-off Date Principal Balance, all interest accruing thereon on and after the Cut-off Date and all collections in respect of interest and principal due after the Cut-off Date; (ii) property which secured each such Mortgage Loan and which has been acquired by foreclosure or deed in lieu of foreclosure; (iii) its interest in any insurance policies in respect of the Mortgage Loans; (iv) its interest in the MI Policies; (v) the rights of the Depositor under the Purchase Agreement; (vi) its interest in the Hedge Agreements; (vii) all other assets included or to be included in the Trust Fund; and (viii) all proceeds of any of the foregoing. Such assignment includes all interest and principal due to the Depositor or the Servicer after the Cut-off Date with respect to the Mortgage Loans.

In connection with such transfer and assignment, the Sponsor, on behalf of the Depositor, does hereby deliver to, and deposit with the Custodian, as the designated agent holding on behalf of the Trustee, the following documents or instruments with respect to each Mortgage Loan so transferred and assigned (with respect to each Mortgage Loan, a “Mortgage File”):

(i) the original Mortgage Note endorsed to “Deutsche Bank National Trust Company, as Trustee for the NovaStar Home Equity Loan Asset-Backed Certificates, Series 2006-4” or in blank;

(ii) the original Mortgage with evidence of recording thereon, or, if the original Mortgage has not yet been returned from the public recording office, a copy of the original Mortgage certified by the Sponsor or the public recording office in which such original Mortgage has been recorded, and if the Mortgage Loan is registered on the MERS System, such Mortgage shall include thereon a statement that it is a MOM Loan and shall include the MIN for such Mortgage Loan;

(iii) unless the Mortgage Loan is registered on the MERS System, an original assignment (which may be included in one or more blanket assignments if permitted by applicable law) of the Mortgage endorsed to “Deutsche Bank National Trust Company, as Trustee for the NovaStar Home Equity Loan Asset-Backed Certificates, Series 2006-4”, and otherwise in recordable form;

(iv) originals of any intervening assignments of the Mortgage showing an unbroken chain of title from the originator thereof to the Person assigning it to the Trustee (or to MERS, if the Mortgage Loan is registered on the MERS System), and noting the presence of a MIN (if the Mortgage Loan is registered on the MERS System), with evidence of recording thereon, or, if the original of any such intervening assignment has not yet been returned from the public recording office, a copy of such original intervening assignment certified by the Sponsor or the public recording office in which such original intervening assignment has been recorded;

(v) the original policy of title insurance (or a commitment for title insurance, if the policy is being held by the title insurance company pending recordation of the Mortgage); and

(vi) a true and correct copy of each assumption, modification, consolidation or substitution agreement, if any, relating to the Mortgage Loan.

If a material defect in any Mortgage File is discovered which may materially and adversely affect the value of the related Mortgage Loan, or the interests of the Trustee or the Certificateholders in such Mortgage Loan, including if any document required to be delivered to the Custodian has not been delivered (provided that a Mortgage File will not be deemed to contain a defect for an unrecorded assignment under clause (iii) above for 180 days following submission of the assignment if the Sponsor has submitted such assignment for recording

pursuant to the terms of the following paragraph), the Sponsor shall cure such defect or repurchase the related Mortgage Loan at the Repurchase Price or substitute an Eligible Substitute Mortgage Loan for the related Mortgage Loan upon the same terms and conditions set forth in Section 3.01 of the Purchase Agreement for breaches of representations and warranties.

Promptly after the Closing Date in the case of a Mortgage Loan (or after the date of transfer of any Eligible Substitute Mortgage Loan), the Sponsor at its own expense shall complete and submit for recording in the appropriate public office for real property records each of the assignments referred to in clause (iii) above, with such assignment completed in favor of the Trustee, excluding any Mortgage Loan that is registered on the MERS System, if MERS is identified on the Mortgage, or on a properly recorded assignment of Mortgage as the mortgagee of record. While such assignment to be recorded is being recorded, the Custodian shall retain a photocopy of such assignment. If any assignment is lost or returned unrecorded to the Custodian because of any defect therein, the Sponsor is required to prepare a substitute assignment or cure such defect, as the case may be, and the Sponsor shall cause such substitute assignment to be recorded in accordance with this paragraph.

In instances where an original Mortgage or any original intervening assignment of Mortgage is not, in accordance with clause (ii) or (iv) above, delivered by the Sponsor to the Custodian, on behalf of the Trustee, prior to or on the Closing Date in the case of a Mortgage Loan, the Sponsor will deliver or cause to be delivered the originals of such documents to the Custodian, on behalf of the Trustee, promptly upon receipt thereof.

In connection with the assignment of any Mortgage Loan registered on the MERS System, promptly after the Closing Date in the case of a Mortgage Loan (or after the date of transfer of any Eligible Substitute Mortgage Loan), the Sponsor further agrees that it will cause, at the Sponsor’s own expense, the MERS System to indicate that such Mortgage Loan has been assigned by the Sponsor to the Trustee in accordance with this Agreement for the benefit of the Certificateholders by including (or deleting, in the case of Mortgage Loans which are repurchased in accordance with this Agreement) in its computer files (a) the applicable Trustee code in the field “Trustee” which identifies the Trustee and (b) the code “NovaStar 2006-4” (or its equivalent) in the field “Pool Field” which identifies the series of the Certificates issued in connection with such Mortgage Loans. The Sponsor further agrees that it will not, and will not permit the Servicer to, and the Servicer agrees that it will not, alter the codes referenced in this paragraph with respect to any such Mortgage Loan during the term of this Agreement unless and until such Mortgage Loan is repurchased in accordance with the terms of this Agreement.

Effective on the Closing Date, the Trustee, on behalf of the Certificateholders, hereby acknowledges its acceptance of all right, title and interest to the Mortgage Loans and other property, existing on the Closing Date and thereafter created and conveyed to it pursuant to this Section 2.01.

The Trustee, as assignee or transferee of the Depositor, shall be entitled to all scheduled principal payments due after the Cut-off Date, all other payments of principal due and collected after the Cut-off Date, and all payments of interest on the Mortgage Loans. No scheduled payments of principal due on or before the Cut-off Date and collected after the Cut-off Date shall belong to the Depositor pursuant to the terms of the Purchase Agreement. Any late payment charges collected in connection with a Mortgage Loan shall be paid to the Servicer as provided in Section 3.15(b) hereof.

The parties hereto intend that the transactions set forth herein constitute a sale by the Depositor to the Issuing Entity on the Closing Date of all the Depositor’s right, title and interest in and to the Mortgage Loans and other property as and to the extent described above. In the event the transactions set forth herein shall be deemed not to be a sale, the Depositor hereby grants to the Trustee, on behalf of the Certificateholders, as of the Closing Date a security interest in all of the Depositor’s right, title and interest in, to and under the Mortgage Loans and such other property, to secure all of the Depositor’s obligations hereunder and this Agreement shall constitute a security agreement under applicable law and in such event, the parties hereto acknowledge that the Custodian, in addition to holding the Mortgage Loans on behalf of the Trustee for the benefit of the Certificateholders, holds the Mortgage Loans as designee of the Depositor. The Sponsor agrees to take or cause to be taken such actions and to execute such documents, including without limitation the filing of all necessary UCC-1 financing statements in the State of Virginia (which shall have been submitted for filing as of the Closing Date), any continuation statements with respect thereto and any amendments thereto required to reflect a change in the name or corporate structure of the Sponsor or the filing of any additional UCC-1 financing statements due to the change in the state of incorporation of the Sponsor, as are necessary to perfect and protect the interests of the Issuing Entity and its assignees in each Mortgage Loan and the proceeds thereof.

Section 2.02 Acceptance of Mortgage Loans by Custodian, on behalf of the Trustee.

(a) The Custodian, on behalf of the Trustee, acknowledges receipt of, subject to the review described below and any exceptions it notes pursuant to the procedures described below, the documents (or certified copies thereof) referred to in Section 2.01 hereof and declares that it holds and will continue to hold those documents and any amendments, replacements or supplements thereto and all other assets of the Trust Fund in trust for the use and benefit of all present and future Certificateholders. No later than 45 days after the Closing Date (or, with respect to any Eligible Substitute Mortgage Loan, within 5 Business Days after the receipt by the Custodian, on behalf of the Trustee, thereof and, with respect to any documents received beyond 45 days after the Closing Date, promptly thereafter), the Custodian agrees, for the benefit of the Certificateholders, to review each Mortgage File delivered to it and to execute and deliver, or cause to be executed and delivered, to the Sponsor, the Depositor and the Trustee an initial certification in the form annexed hereto as Exhibit F-1. In conducting such review, the Custodian will ascertain whether all required documents described in Section 2.01 hereof have been executed and received and whether those documents relate, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans it has received, as identified in Exhibit B to this Agreement, as supplemented (provided, however, that with respect to those documents described in subclause (vii) of such section, the Custodian’s obligations shall extend only to documents actually delivered pursuant to such subclause). In performing any such review, the Custodian may conclusively rely on the purported due execution and genuineness of any such document and on the purported genuineness of any signature thereon. If the Custodian finds that any document constituting part of the Mortgage File not to have been executed or received, or to be unrelated to the Mortgage Loans identified in

Exhibit B or to appear to be defective on its face, the Custodian, on behalf of the Trustee, shall promptly notify the Sponsor and the Trustee of such finding and the Sponsor’s obligation to cure such defect or repurchase or substitute for the related Mortgage Loan.

(b) No later than 180 days after the Closing Date, the Custodian, on behalf of the Trustee, will review, for the benefit of the Certificateholders, the Mortgage Files and will execute and deliver or cause to be executed and delivered to the Sponsor ,the Depositor and the Trustee, a final certification in the form annexed hereto as Exhibit F-2. In conducting such review, the Custodian, on behalf of the Trustee, will ascertain whether an original of each document described in subclauses (ii)-(iv) of Section 2.01 hereof required to be recorded has been returned from the recording office with evidence of recording thereon or a certified copy has been obtained from the recording office. If the Custodian finds any document constituting part of the Mortgage File has not been received, or to be unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in Exhibit B or to appear defective on its face, the Custodian, on behalf of the Trustee, shall promptly notify the Sponsor and the Trustee of such finding and the Sponsor’s obligation to cure such defect or repurchase or substitute for the related Mortgage Loan.

(c) Upon deposit of the Repurchase Price in the Collection Account and notification of the Trustee, by a certification signed by a Servicing Officer (which certification shall include a statement to the effect that the Repurchase Price has been deposited in the Collection Account), upon receipt of a Request for Release the Custodian shall release to the Sponsor the related Mortgage File and the Trustee shall execute and deliver all instruments of transfer or assignment, without recourse, furnished to it by the Sponsor as are necessary to vest in the Sponsor title to and rights under the related Mortgage Loan. Such purchase shall be deemed to have occurred on the date on which certification of the deposit of the Repurchase Price in the Distribution Account was received by the Trustee. The Custodian, on behalf of the Trustee, shall amend the applicable Mortgage Loan Schedule to reflect such repurchase and shall forward it to the Trustee. The Trustee shall promptly notify the Servicer and the Rating Agencies of such amendment.

Section 2.03 Repurchase or Substitution of Mortgage Loans by the Sponsor.

(a) Upon discovery or receipt of written notice of any materially defective document in, or that a document is missing from, a Mortgage File or of the breach by the Sponsor of any representation, warranty or covenant under the Purchase Agreement in respect of any Mortgage Loan which materially adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, the party making such discovery or receiving such notice shall promptly notify the other parties hereto, and the Sponsor shall thereupon be required to deliver such missing document or cure such defect or breach no later than 90 days from the date of the discovery or receipt of written notice of such missing document, defect or breach, and if the Sponsor does not deliver such missing document or cure such defect or breach in all material respects during such period, the Custodian shall notify the Trustee and the Trustee shall enforce the Sponsor’s obligation under the Purchase Agreement and cause the Sponsor to repurchase such Mortgage Loan from the Trust Fund at the Repurchase Price on or prior to the Determination Date following the expiration of such 90 day period.

(b) The Repurchase Price for the repurchased Mortgage Loan shall be deposited in the Collection Account and the Trustee, shall receive written certification from the Servicer of such deposit and upon receipt of a Request for Release the Custodian shall release to the Sponsor the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Sponsor shall furnish to it and as shall be necessary to vest in the Sponsor any Mortgage Loan released pursuant hereto and the Trustee and the Custodian shall have no further responsibility with regard to such Mortgage File (it being understood that neither the Trustee nor the Custodian shall have any responsibility for determining the sufficiency of such assignment for its intended purpose). In lieu of repurchasing any such Mortgage Loan as provided above, the Sponsor may cause such Mortgage Loan to be removed from the Trust Fund (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Eligible Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(d). It is understood and agreed that the obligation of the Sponsor to cure or to repurchase (or to substitute for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy against the Sponsor respecting such omission, defect or breach available to the Trustee on behalf of the Certificateholders.

(c) Within 90 days of the earlier of discovery by the Servicer or receipt of notice by the Servicer of the breach of any representation, warranty or covenant of the Servicer set forth in Section 2.05 which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the Servicer shall cure such breach in all material respects.

(d) Any substitution of Eligible Substitute Mortgage Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected prior to the last Business Day that is within two years after the Closing Date. As to any Deleted Mortgage Loan for which the Sponsor substitutes an Eligible Substitute Mortgage Loan or Loans, such substitution shall be effected by the Sponsor delivering to the Custodian, for such Eligible Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2.01, together with an Officers’ Certificate providing that each such Eligible Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Adjustment Amount (as described below), if any, in connection with such substitution. The Custodian shall acknowledge receipt for such Eligible Substitute Mortgage Loan or Loans and, within ten Business Days thereafter, shall review such documents as specified in Section 2.02 and deliver to the Servicer and the Trustee, with respect to such Eligible Substitute Mortgage Loan or Loans, a certification substantially in the form attached hereto as Exhibit F-1, with any applicable exceptions noted thereon. Within one year of the date of substitution, the Custodian shall deliver to the Servicer and the Trustee a certification substantially in the form of Exhibit F-2 hereto with respect to such Eligible Substitute Mortgage Loan or Loans, with any applicable exceptions noted thereon. Monthly Payments due with respect to Eligible Substitute Mortgage Loans in the month of substitution are not part of the Trust Fund and will be retained by the Sponsor. For the month of substitution, distributions to Certificateholders will reflect the collections and recoveries in respect of such Deleted Mortgage Loan in the Due Period preceding the month of substitution and the Sponsor shall thereafter be entitled to retain all amounts subsequently received in respect

of such Deleted Mortgage Loan. The Sponsor shall give or cause to be given written notice to the Certificateholders that such substitution has taken place, shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Eligible Substitute Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan Schedule to the Custodian and the Trustee. Upon such substitution by the Sponsor, such Eligible Substitute Mortgage Loan or Loans shall constitute part of the Mortgage Pool and shall be subject in all respects to the terms of this Agreement and the Purchase Agreement, including all applicable representations and warranties thereof included in the Purchase Agreement as of the date of substitution.

For any month in which the Sponsor substitutes one or more Eligible Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Servicer will determine the amount (the “Substitution Adjustment Amount”), if any, by which the aggregate Repurchase Price of all such Deleted Mortgage Loans exceeds the aggregate, as to each such Eligible Substitute Mortgage Loan, of the principal balance thereof as of the date of substitution, together with one month’s interest on such principal balance at the applicable Net Mortgage Rate. On the date of such substitution, the Sponsor will deliver or cause to be delivered to the Servicer for deposit in the Collection Account an amount equal to the Substitution Adjustment Amount, if any, and the Custodian, upon receipt of the related Eligible Substitute Mortgage Loan or Loans and certification by the Servicer of such deposit (which shall be delivered to the Trustee and the Custodian), shall release to the Sponsor the related Mortgage File or Files and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Sponsor shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto.

In addition, the Sponsor shall obtain at its own expense and deliver to the Trustee an Opinion of Counsel to the effect that such substitution will not cause (a) any federal tax to be imposed on the Issuing Entity, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(a)(l) of the Code or on “contributions after the startup date” under Section 860G(d)(l) of the Code, or (b) any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificate is outstanding. If such Opinion of Counsel can not be delivered, then such substitution may only be effected at such time as the required Opinion of Counsel can be given.

(e) Upon discovery by the Sponsor, the Servicer, the Custodian or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall within two Business Days give written notice thereof to the other parties. In connection therewith, the Sponsor or the Depositor, as the case may be, shall repurchase or, subject to the limitations set forth in Section 2.03(d), substitute one or more Eligible Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Such repurchase or substitution shall be made by the Sponsor. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.03(a). The Trustee shall reconvey to the Sponsor, the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty.

Section 2.04 Acknowledgement of Trustee.

The Trustee acknowledges that in the event that any transfer of the Mortgage Loans and the MI Policies from the Sponsor to the Depositor, or from the Depositor to the Trustee on behalf of the Certificateholders, is determined to constitute a financing, then in each case the Custodian, on behalf of the Trustee, will hold the Mortgage Loans and the MI Policies as the designee and bailee of the Depositor subject, however, in each case, to a prior lien in favor of the Certificateholders pursuant to the terms of this Agreement.

Section 2.05 Representations, Warranties and Covenants of the Servicer.

ARTICLE III

ADMINISTRATION AND SERVICING

OF THE MORTGAGE LOANS

Section 3.01 Servicer to Assure Servicing.

(a) The Servicer shall supervise, or take such actions as are necessary to ensure, the servicing and administration of the Mortgage Loans and any REO Property in accordance with all applicable requirements of the Servicing Criteria, with this Agreement and with its normal servicing practices, which generally shall conform to the standards of an institution prudently servicing mortgage loans for its own account and shall have full authority to do anything it reasonably deems appropriate or desirable in connection with such servicing and administration. The Servicer may perform its responsibilities relating to servicing through other agents or independent contractors, but shall not thereby be released from any of its responsibilities as hereinafter set forth. Subject to Section 3.06(b), the authority of the Servicer,

in its capacity as Servicer, and any Subservicer acting on its behalf, shall include, without limitation, the power to (i) consult with and advise any Subservicer regarding administration of a related Mortgage Loan, (ii) approve any recommendation by a Subservicer to foreclose on a related Mortgage Loan, (iii) supervise the filing and collection of insurance claims and take or cause to be taken such actions on behalf of the insured Person thereunder as shall be reasonably necessary to prevent the denial of coverage thereunder, and (iv) effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing a related Mortgage Loan, including the employment of attorneys, the institution of legal proceedings, the collection of deficiency judgments, the acceptance of compromise proposals and any other matter pertaining to a delinquent Mortgage Loan. The authority of the Servicer shall include, in addition, the power on behalf of the Certificateholders, the Trustee, or any of them to (i) execute and deliver customary consents or waivers and other instruments and documents, (ii) consent to transfer of any related Mortgaged Property and assumptions of the related Mortgage Notes and Mortgages (in the manner provided in this Agreement) and (iii) collect any Insurance Proceeds and Liquidation Proceeds. Without limiting the generality of the foregoing, the Servicer and any Subservicer acting on its behalf may, and is hereby authorized, and empowered by the Trustee when the Servicer believes it is reasonably necessary in its best judgment in order to comply with its servicing duties hereunder, to execute and deliver, on behalf of itself, the Certificateholders, the Trustee, or any of them, any instruments of satisfaction, cancellation, partial or full release, discharge and all other comparable instruments, with respect to the related Mortgage Loans, the insurance policies and the accounts related thereto, and the Mortgaged Properties. The Servicer may exercise this power in its own name or in the name of a Subservicer.

The Servicer, in such capacity, may not consent to the placing of a lien senior to that of the Mortgage on the related Mortgaged Property.

The relationship of the Servicer (and of any successor to the Servicer as servicer under this Agreement) to the Issuing Entity and the Trustee under this Agreement is intended by the parties to be that of an independent contractor and not that of a joint venturer, partner or agent.

(b) Notwithstanding the provisions of Subsection 3.01(a), the Servicer shall not take any action inconsistent with the interests of the Trustee, or the Certificateholders or with the rights and interests of the Trustee, or the Certificateholders under this Agreement.

(c) The Trustee shall furnish the Servicer with any powers of attorney in the form of Exhibit P and other documents in form as provided to it necessary or appropriate to enable the Servicer to service and administer the related Mortgage Loans and REO Property and the Trustee shall not be liable for the actions of or the use or misuse by the Servicer or any Subservicers under such powers of attorney.

(d) The Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, when the Servicer believes it is appropriate in its best judgment to register any Mortgage Loan on the MERS System, or cause the removal from the registration of any Mortgage Loan on the MERS System, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in

the name of MERS, solely as nominee for the Trustee and its successors and assigns. Any expenses incurred in connection with the actions described in the preceding sentence shall be borne by the Servicer with no right of reimbursement; provided, that if, as a result of MERS discontinuing or becoming unable to continue operations in connection with the MERS System, it becomes necessary to remove any Mortgage Loan from registration on the MERS System and to arrange for the assignment of the related Mortgages to the Trustee, then any related expenses shall be reimbursable to the Servicer by the Issuing Entity.

Section 3.02 Subservicing Agreements Between Servicer and Subservicers.

(a) The Servicer may enter into Subservicing Agreements with Subservicers for the servicing and administration of the Mortgage Loans and for the performance of any and all other activities of the Servicer hereunder. Each Subservicer shall be either (i) an institution the accounts of which are insured by the FDIC or (ii) another entity that engages in the business of originating or servicing mortgage loans comparable to the Mortgage Loans, and in either case shall be authorized to transact business in the state or states in which the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to enable the Subservicer to perform its obligations hereunder and under the Subservicing Agreement. Any Subservicing Agreement entered into by the Servicer shall include the provision that such Agreement may be immediately terminated (i) (x) with cause and without any termination fee by the Servicer hereunder and/or (y) without cause, in which case the Servicer shall be solely responsible for any termination fee or penalty resulting therefrom and (ii) at the option of the Trustee upon the termination or resignation of the Servicer hereunder, in which case the Servicer shall be solely responsible for any termination fee or penalty resulting therefrom. In addition, each Subservicing Agreement shall provide for servicing of the Mortgage Loans consistent with the terms of this Agreement. The Servicer and the Subservicers may enter into Subservicing Agreements and make amendments to the Subservicing Agreements or enter into different forms of Subservicing Agreements providing for, among other things, the delegation by the Servicer to a Subservicer of additional duties regarding the administration of the Mortgage Loans; provided, however, that any such amendments or different forms shall be consistent with and not violate the provisions of this Agreement, and that no such amendment or different form shall be made or entered into which could be reasonably expected to be materially adverse to the interests of the Certificateholders, without the consent of the Certificateholders holding at least 51% of the aggregate Voting Rights.

(b) As part of its servicing activities hereunder, the Servicer, for the benefit of the Trustee, and the Certificateholders, shall enforce the obligations of each Subservicer under the related Subservicing Agreement. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Subservicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Servicer shall pay the costs of such enforcement at its own expense, but shall be reimbursed therefor only (i) from a general recovery resulting from such enforcement only to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loan or (ii) from a specific recovery of costs, expenses or attorneys’ fees against the party against whom such enforcement is directed.

(c) The Servicer shall not permit a Subservicer, subcontractor or Servicing Function Participant to perform any servicing function hereunder with respect to the Mortgage Loans unless such Servicing Function Participant first agrees in writing with the Servicer to deliver an Assessment of Compliance and an Attestation Report in such manner and at such time that permits the Servicer to comply with Section 3.17 hereof.

Section 3.03 Successor Subservicers.

The Servicer shall be entitled to terminate any Subservicing Agreement that may exist in accordance with the terms and conditions of such Subservicing Agreement and without any limitation by virtue of this Agreement; provided, however, that upon termination, the Servicer shall either act as servicer of the related Mortgage Loans or enter into an appropriate contract with a successor Subservicer reasonably acceptable to the Depositor (and written notice to the Trustee), pursuant to which such successor Subservicer will be bound by all relevant terms of the related Subservicing Agreement pertaining to the servicing of such Mortgage Loans.

Section 3.04 Liability of the Servicer.

(a) Notwithstanding any Subservicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between the Servicer and a Subservicer or reference to actions taken through a Subservicer or otherwise, the Servicer shall under all circumstances remain obligated and primarily liable to the Trustee and the Certificateholders for the servicing and administering of the Mortgage Loans and any REO Property in accordance with this Agreement. The obligations and liability of the Servicer shall not be diminished by virtue of Subservicing Agreements or by virtue of indemnification of the Servicer by any Subservicer, or any other Person. The obligations and liability of the Servicer shall remain of the same nature and under the same terms and conditions as if the Servicer alone were servicing and administering the related Mortgage Loans. The Servicer shall, however, be entitled to enter into indemnification agreements with any Subservicer or other Person and nothing in this Agreement shall be deemed to limit or modify such indemnification. For the purposes of this Agreement, the Servicer shall be deemed to have received any payment on a Mortgage Loan on the date the Subservicer received such payment.

(b) Any Subservicing Agreement that may be entered into and any transactions or services relating to the Mortgage Loans involving a Subservicer in its capacity as such and not as an originator shall be deemed to be between the Subservicer and the Servicer alone, and the Custodian, the Trustee and the Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Subservicer, except as set forth in Section 3.05.

Section 3.05 Assumption or Termination of Subservicing Agreements by the Trustee.

(a) If the Trustee or its designee as the successor Servicer, shall assume the servicing obligations of the Servicer in accordance with Section 7.02 below, the Trustee or its designee as the successor Servicer, to the extent necessary to carry out the provisions of Section 7.02 with respect to the Mortgage Loans, shall succeed to all of the rights and obligations of the

Servicer under each of the Subservicing Agreements. In such event, the Trustee or its designee as the successor Servicer shall be deemed to have assumed all of the Servicer’s rights and obligations therein and to have replaced the Servicer as a party to such Subservicing Agreements to the same extent as if such Subservicing Agreements had been assigned to the Trustee or its designee as a successor Servicer, except that the Trustee or its designee as a successor Servicer shall not be deemed to have assumed any obligations or liabilities of the Servicer arising prior to such assumption or as a result of the Trustee’s or its designee’s terminating any Subservicer upon the Trustee or its designee becoming successor Servicer and the Servicer shall not thereby be relieved of any liability or obligations under such Subservicing Agreements arising prior to such assumption or as a result of the Trustee’s or its designee’s terminating any Subservicer upon the Trustee or its designee becoming successor Servicer.

(b) The Trustee or its designee as the successor Servicer may terminate any Subservicer upon becoming successor Servicer. Any termination fees will be paid by the terminated Subservicer.

(c) In the event that the Trustee or its designee as successor Servicer assumes the servicing obligations of the Servicer under Section 7.02, upon the request of the Trustee or such designee as successor Servicer, the Servicer shall at its own expense deliver to the Trustee, or at the Trustee’s written request to such designee, originals or, if originals are not available, photocopies of all documents, files and records, electronic or otherwise, relating to the Subservicing Agreements and the related Mortgage Loans or REO Property then being serviced and an accounting of amounts collected and held by it, if any, and will otherwise cooperate and use its reasonable efforts to effect the orderly and efficient transfer of the Subservicing Agreements, or responsibilities hereunder to the Trustee, or at its written request to such designee, as successor Servicer.

Section 3.06 Collection of Mortgage Loan Payments.

(a) The Servicer will coordinate and monitor remittances by Subservicers to it with respect to the Mortgage Loans in accordance with this Agreement.

(b) The Servicer shall make its best reasonable efforts to collect or cause to be collected all payments required under the terms and provisions of the Mortgage Loans and shall follow, and use its best reasonable efforts to cause Subservicers to follow, collection procedures comparable to the collection procedures of prudent mortgage lenders servicing mortgage loans for their own account to the extent such procedures shall be consistent with this Agreement. Consistent with the foregoing, the Servicer or the related Subservicer may in its discretion (i) waive or permit to be waived any late payment charge, prepayment charge, assumption fee, or any penalty interest in connection with the prepayment of a Mortgage Loan and (ii) suspend or reduce or permit to be suspended or reduced regular monthly payments for a period of up to six months, or arrange or permit an arrangement with a Mortgagor for a scheduled liquidation of delinquencies; provided, however, that the Servicer or the related Subservicer may permit the foregoing only if it believes, in good faith, that recoveries of Monthly Payments will be maximized; provided further, however, with respect to Mortgage Loans insured by an MI Policy, that the Servicer may not without the prior written consent of the MI Insurer permit any waiver, modification or variance which would (a) reduce or eliminate the coverage provided under the

MI Policy (b) change the loan rate, (c) forgive any payment of principal or interest, (d) lessen the lien priority or (e) extend the final maturity date of a Mortgage Loan past 12 months after the original maturity date on such Mortgage Loan. In the event the Servicer or related Subservicer shall consent to the deferment of the due dates for payments due on a Mortgage Note, the Servicer shall nonetheless make an Advance or shall cause the related Subservicer to make an advance to the same extent as if such installment were due, owing and delinquent and had not been deferred through liquidation of the Mortgaged Property; provided, however, that the obligation of the Servicer or the related Subservicer to make an Advance shall apply only to the extent that the Servicer believes, in good faith, that such advances are not Nonrecoverable Advances. The Servicer shall pay the amount of any waived prepayment charge at the time of payoff if such prepayment charge was waived for a reason other than that specified in this Section 3.06(b).

(c) Within five Business Days after the Servicer has determined that all amounts which it expects to recover from or on account of a Liquidated Mortgage Loan have been recovered and that no further Liquidation Proceeds will be received in connection therewith, the Servicer shall provide to the Trustee a certificate of a Servicing Officer that such Mortgage Loan became a Liquidated Mortgage Loan as of the date of such determination.

(d) The Servicer shall establish a segregated account (the “Collection Account”), which shall be an Eligible Account, which shall be titled “Collection Account, Deutsche Bank National Trust Company, as Trustee for the registered holders of NovaStar Mortgage Funding Trust 2006-4, Home Equity Loan Asset-Backed Certificates, Series 2006-4”, in which the Servicer shall deposit or cause to be deposited any amounts representing payments on and any collections in respect of the Mortgage Loans received by it after the Cut-off Date (other than in respect of the payments referred to in the following paragraph) within two Business Days following receipt thereof, including the following payments and collections received or made by it (without duplication):

(i) all payments of principal or interest on the Mortgage Loans received by the Servicer directly from Mortgagors or from the respective Subservicer;

(ii) the aggregate Repurchase Price of the Mortgage Loans purchased by the Servicer pursuant to Section 3.19;

(iii) Net Liquidation Proceeds;

(iv) all proceeds of any Mortgage Loans repurchased by the Sponsor pursuant to the Purchase Agreement, and all Substitution Adjustment Amounts required to be deposited in connection with the substitution of an Eligible Substitute Mortgage Loan pursuant to the Purchase Agreement;

(v) Insurance Proceeds, other than Net Liquidation Proceeds, and MI Insurance Proceeds resulting from any insurance policy maintained on a Mortgaged Property;

(vi) any Advance and any Compensating Interest payments; and

(vii) any other amounts received by the Servicer, including all Foreclosure Profits, assumption fees, prepayment penalties and any other fees that are required to be deposited in the Collection Account pursuant to this Agreement;

provided, however, that with respect to each Due Period, the Servicer shall be permitted to retain from payments actually collected in respect of interest on the Mortgage Loans, the Servicing Fee for such Due Period. The foregoing requirements respecting deposits to the Collection Account are exclusive, it being understood that, without limiting the generality of the foregoing, the Servicer need not deposit in the Collection Account late payment charges payable by Mortgagors, as further described in Section 3.15, or amounts received by the Subservicer for the accounts of Mortgagors for application towards the payment of taxes, insurance premiums, assessments and similar items. In the event any amount not required to be deposited in the Collection Account is so deposited, the Servicer may at any time (prior to being terminated under this Agreement) withdraw such amount from the Collection Account, any provision herein to the contrary notwithstanding. The Servicer shall keep records that accurately reflect the funds on deposit in the Collection Account that have been identified by it as being attributable to the Mortgage Loans and shall hold all collections in the Collection Account for the benefit of the Trustee, and the Certificateholders, as their interests may appear.

Funds in the Collection Account may be invested in Eligible Investments with a maturity date no later than the Business Day immediately preceding the Servicer Remittance Date, but shall not be commingled with the Servicer’s own funds or general assets or with funds respecting payments on mortgage loans or with any other funds not related to the Certificates. All such investments shall be made in the name of the Trustee for the benefit of the Certificateholders, provided, however, that income earned on such Eligible Investments shall be for the account of the Servicer. The Servicer shall be obligated to cover losses on such Eligible Investments.

(e) The Servicer will require each Subservicer to hold all funds constituting collections on the Mortgage Loans, pending remittance thereof to the Servicer, in one or more accounts in the name of the Trustee meeting the requirements of an Eligible Account, and such funds shall not be invested. The Subservicer shall segregate and hold all funds collected and received pursuant to each Mortgage Loan separate and apart from any of its own funds and general assets and any other funds. Each Subservicer shall make remittances to the Servicer no later than one Business Day following receipt thereof and the Servicer shall deposit into the Collection Account any such remittances received from any Subservicer within one Business Day following receipt by the Servicer.

Section 3.07 Withdrawals from the Collection Account.

(a) The Servicer shall, from time to time as provided herein, make withdrawals from the Collection Account of amounts on deposit therein pursuant to Section 3.06 that are attributable to the Mortgage Loans for the following purposes (without duplication):

(i) to deposit in the Distribution Account, by the Servicer Remittance Date prior to each Distribution Date, all collections on the Mortgage Loans required to be distributed from the Distribution Account on a Distribution Date;

(ii) to the extent deposited to the Collection Account, to reimburse itself or the related Subservicer for previously unreimbursed expenses incurred in maintaining individual insurance policies pursuant to Section 3.11, or Liquidation Expenses, paid pursuant to Section 3.13, such withdrawal right being limited to amounts received on particular Mortgage Loans (other than any Repurchase Price in respect thereof) which represent late recoveries of the payments for which such expenses were paid, or from related Liquidation Proceeds;

(iii) to pay to itself out of each payment received on account of interest on a Mortgage Loan as contemplated by Section 3.15, an amount equal to the related Servicing Fee (to the extent not retained pursuant to Section 3.06);

(iv) to pay to itself or the Sponsor, with respect to any Mortgage Loan or property acquired in respect thereof that has been purchased by the Sponsor, the Servicer or other entity, all amounts received thereon and not required to be distributed to Certificateholders as of the date on which the related Repurchase Price is determined;

(v) to reimburse the Servicer or any Subservicer for any unreimbursed Advance of its own funds or any unreimbursed advance of such Subservicer’s own funds, the right of the Servicer or a Subservicer to reimbursement pursuant to this subclause (v) being limited to amounts received on a particular Mortgage Loan (including, for this purpose, the Repurchase Price therefor, Insurance Proceeds and Liquidation Proceeds) which represent late payments or recoveries of the principal of or interest on such Mortgage Loan respecting which such Advance or advance was made;

(vi) to reimburse the Servicer or any Subservicer from Insurance Proceeds or Liquidation Proceeds relating to a particular Mortgage Loan for amounts expended by the Servicer or such Subservicer pursuant to Section 3.13: (x) in good faith in connection with the restoration of the related Mortgaged Property which was damaged by the uninsured cause, (y) in connection with the liquidation of such Mortgage Loan, or (z) with respect to an MI Claim Payment Advance made by the Servicer with respect to such Mortgage Loan;

(vii) to reimburse the Servicer or any Subservicer for any unreimbursed Nonrecoverable Advance previously made, and otherwise not reimbursed pursuant to this Section 3.07(a);

(viii) to withdraw any other amount deposited in the Collection Account that was not required to be deposited therein pursuant to Section 3.06;

(ix) to reimburse the Servicer for costs associated with the environmental report handling the presence of any toxic or hazardous substance on a Mortgaged Property as set forth in Section 3.13(c);

(x) to clear and terminate the Collection Account upon a termination pursuant to Section 7.08;

(xi) to pay to the Servicer income earned on Eligible Investments in the Collection Account;

(xii) to pay to the MI Insurer the monthly MI Premiums due under each MI Policy from payments received (or Advances made) on account of interest due on the related Mortgage Loan; and

(xiii) to make an Advance with respect to a Mortgage Loan that is Delinquent from funds held in the Collection Account as contemplated by Section 3.25, provided that the amount withdrawn for such an Advance is immediately deposited into the Distribution Account.

Withdrawals made pursuant to clause (xii) shall be made on a first priority basis. In connection with withdrawals pursuant to clauses (ii), (iii), (iv), (v) and (vi), the Servicer’s entitlement thereto is limited to collections or other recoveries on the related Mortgage Loan, and 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 Collection Account pursuant to such clauses.

(b) Notwithstanding the provisions of this Section 3.07, the Servicer may, but is not required to, allow the Subservicers to deduct from amounts received by them or from the related account maintained by a Subservicer, prior to deposit in the Collection Account, any portion to which such Subservicers are entitled as reimbursement of any reimbursable Advances made by such Subservicers.

Section 3.08 Collection of Taxes, Assessments and Similar Items; Servicing Accounts.

(a) The Servicer shall establish and maintain or cause the related Subservicer to establish and maintain, one or more Servicing Accounts. The Servicer or a Subservicer will deposit and retain therein all collections from the Mortgagors for the payment of taxes, assessments, insurance premiums, or comparable items as agent of the Mortgagors.

(b) The deposits in the Servicing Accounts shall be held in trust by the Servicer or a Subservicer (and its successors and assigns) in the name of the Trustee. Such Servicing Accounts shall be Eligible Accounts and, if permitted by applicable law, invested in Eligible Investments held in trust by the Servicer or a Subservicer as described above and maturing, or be subject to redemption or withdrawal, no later than the date on which such funds are required to be withdrawn, and in no event later than 45 days after the date of investment; withdrawals of amounts from the Servicing Accounts may be made only to effect timely payment of taxes, assessments, insurance premiums, or comparable items, to reimburse the

Servicer or a Subservicer for any advances made with respect to such items, to refund to any Mortgagors any sums as may be determined to be overages, to pay interest, if required, to Mortgagors on balances in the Servicing Accounts or to clear and terminate the Servicing Accounts at or any time after the termination of this Agreement. Amounts received from Mortgagors for deposit into the Servicing Accounts shall be deposited in the Servicing Accounts by the Servicer within two days of receipt. The Servicer shall advance from its own funds amounts needed to pay items payable from the Servicing Accounts if the Servicer reasonably believes that such amounts are recoverable from the related Mortgagor. The Servicer shall comply with all laws relating to the Servicing Accounts, including laws relating to payment of interest on the Servicing Accounts. If interest earned by the Servicer on the Servicing Accounts is not sufficient to pay required interest on the Servicing Accounts, the Servicer shall pay the difference from its own funds. The Servicing Accounts shall not be the property of the Issuing Entity.

Section 3.09 Access to Certain Documentation and Information Regarding the Mortgage Loans.

The Servicer shall provide, and shall cause any Subservicer to provide, to the Trustee, access to the documentation regarding the related Mortgage Loans and REO Property and to the Certificateholders or Certificate Owners, the FDIC, and the supervisory agents and examiners of the FDIC (to which the Custodian and Trustee shall also provide) access to the documentation regarding the related Mortgage Loans required by applicable regulations, such access being afforded without charge but only upon reasonable request and during normal business hours at the offices of the Servicer or the Subservicers that are designated by these entities (or in the case of the Custodian and the Trustee, during normal business hours at its designated office); provided, however, that, unless otherwise required by law, the Servicer and any Subservicer shall not be required to provide access to such documentation if the provision thereof would violate the legal right to privacy of any Mortgagor; provided, further, however, that the Trustee shall coordinate its request for such access so as not to impose an unreasonable burden on, or cause an unreasonable interruption of, the business of the Servicer or any Subservicer. The Servicer, the Subservicers, the Trustee and the Custodian shall allow representatives of the above entities to photocopy any of the documentation and shall provide equipment for that purpose at a charge that covers their own actual out-of-pocket costs.

Section 3.10 [Reserved].

Section 3.11 Maintenance of Hazard Insurance and Fidelity Coverage.

(a) The Servicer shall maintain and keep, or cause each Subservicer to maintain and keep, with respect to each Mortgage Loan and each REO Property, in full force and effect hazard insurance (fire insurance with extended coverage) equal to at least the lesser of the Principal Balance of the Mortgage Loan or the current replacement cost of the Mortgaged Property, and containing a standard mortgagee clause, provided, however, that the amount of hazard insurance may not be less than the amount necessary to prevent loss due to the application of any co-insurance provision of the related policy. Unless applicable state law requires a higher deductible, the deductible on such hazard insurance policy may be no more than $1,500 or 1% of the applicable amount of coverage, whichever is less. In the case of a condominium unit or a unit

in a planned unit development, the required hazard insurance shall take the form of a multi-peril policy covering the entire condominium project or planned unit development, in an amount equal to at least 100% of the insurable value based on replacement cost. If the Servicer shall obtain and maintain a blanket policy consistent with its general mortgage servicing activities insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations as set forth in this Section 3.11(a), 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 a policy complying with this Section 3.11(a) and there shall have been a loss which would have been covered by such policy, deposit in the Collection Account the amount not otherwise payable under the blanket policy because of such deductible clause without any right of reimbursement. Any such deposit by the Servicer shall be made on the last Business Day of the Due Period in the month in which payments under any such policy would have been deposited in the Collection Account. In connection with its activities as servicer of the Mortgage Loans, the Servicer agrees to present, on behalf of itself, the Issuing Entity, and the Trustee, claims under any such blanket policy.

(b) Any amounts collected by the Servicer or a Subservicer under any such hazard insurance policy (other than amounts to be applied to the restoration or repair of the Mortgaged Property or amounts released to the Mortgagor in accordance with the Servicer’s or a Subservicer’s normal servicing procedures, the Mortgage Note, the Mortgage or applicable law) shall be deposited in the Collection Account.

(c) Any cost incurred by a Servicer or a Subservicer in maintaining any such individual hazard insurance policies shall not be added to the amount owing under the Mortgage Loan for the purpose of calculating monthly distributions to Certificateholders, notwithstanding that the terms of the Mortgage Loan so permit. Such costs of maintaining individual hazard insurance policies shall be recoverable by the Servicer or a Subservicer out of related late payments by the Mortgagor or out of Insurance Proceeds or Liquidation Proceeds or by the Servicer from the Repurchase Price, to the extent permitted by Section 3.07.

(d) No earthquake or other additional insurance is to be required of any Mortgagor or maintained on property acquired with respect to a Mortgage other than pursuant to such applicable laws and regulations as shall at any time be in force and shall require such additional insurance. When, at the time of origination of the Mortgage Loan or at any subsequent time, the Mortgaged Property is located in a federally designated special flood hazard area, the Servicer shall ensure that, with respect to such Mortgage Loan or such REO Property, flood insurance is acquired (to the extent available and in accordance with mortgage servicing industry practice). Such flood insurance shall cover the Mortgaged Property, including all items taken into account in arriving at the Appraised Value on which the Mortgage Loan was based, and shall be in an amount equal to the lesser of (i) the Principal Balance of the related Mortgage Loan and (ii) the minimum amount required under the terms of coverage to compensate for any damage or loss on a replacement cost basis, but not more than the maximum amount of such insurance available for the related Mortgaged Property under either the regular or emergency programs of the National Flood Insurance Program (assuming that the area in which such Mortgaged Property is located is participating in such program). Unless applicable state law requires a higher deductible, the deductible on such flood insurance may not exceed $1,500 or 1% of the applicable amount of coverage, whichever is less.

(e) If insurance complying with Subsections 3.11 (a) and (d) has not been maintained and there shall have been a loss which would have been covered by such insurance had it been maintained, the Servicer shall pay, or cause the related Subservicer to pay, for any necessary repairs without any right of reimbursement.

(f) The Servicer shall present, or cause the related Subservicer to present, claims under any related hazard insurance or flood insurance policy.

(g) The Servicer shall obtain and maintain at its own expense, and shall cause each Subservicer to obtain and maintain at its own expense, and for the duration of this Agreement, a blanket fidelity bond and an errors and omissions insurance policy covering the Servicer’s and such Subservicer’s officers, employees and other persons acting on its behalf in connection with its activities under this Agreement. The amount of coverage shall correspond with the FNMA/FHMLC levels presently maintained by the Servicer. The Servicer shall promptly notify the Trustee of any material change in the terms of such bond or policy. The Servicer shall provide annually by March 31st of each year, to the Trustee a certification stating that such bond and policy are in effect. If any such bond or policy ceases to be in effect, the Servicer shall, to the extent possible, give the Trustee ten days’ notice prior to any such cessation and shall use its reasonable best efforts to obtain a comparable replacement bond or policy, as the case may be. Any amounts relating to the Mortgage Loans collected under such bond or policy shall be deposited in the Collection Account.

Section 3.12 Due-on-Sale Clauses; Assumption Agreements.

(a) In any case in which the Servicer is notified by any Mortgagor or Subservicer that a Mortgaged Property relating to a Mortgage Loan has been or is about to be conveyed by the Mortgagor, the Servicer shall enforce, or shall instruct such Subservicer to enforce, any due-on-sale clause contained in the related Mortgage to the extent permitted under the terms of the related Mortgage Note and by applicable law. The Servicer or the related Subservicer may repurchase a Mortgage Loan at the Repurchase Price when the Servicer requires acceleration of the Mortgage Loan, but only if the Servicer is satisfied, as evidenced by a certification signed by a Servicing Officer delivered to the Trustee, that such Mortgage Loan is in default or default is reasonably foreseeable. If the Servicer reasonably believes that such due-on-sale clause cannot be enforced under applicable law or if the Mortgage Loan does not contain a due-on-sale clause, the Servicer is authorized, and may authorize any Subservicer, to consent to a conveyance subject to the lien of the Mortgage, and, with the consent of the MI Insurer, if applicable, to take or enter into an assumption 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 related Mortgage Note and unless prohibited by applicable state law, on condition, however, that the related Mortgage Loan shall continue to be covered by a hazard policy. In connection with any such assumption, no material term of the related Mortgage Note may be changed. The Servicer shall notify the Custodian and Trustee, whenever possible, before the completion of such assumption agreement, and shall forward to the Custodian the original copy of such assumption agreement, which copy shall be added by the Custodian to the related Mortgage File and which 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.

(b) Notwithstanding the foregoing paragraph or any other provision of this Agreement, the Servicer shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any assumption of a Mortgage Loan by operation of law or any conveyance by the Mortgagor of the related Mortgaged Property or assumption of a Mortgage Loan which the Servicer reasonably believes it may be restricted by law from preventing, for any reason whatsoever or if the exercise of such right would impair or threaten to impair any recovery under any applicable insurance policy.

Section 3.13 Realization Upon Defaulted Mortgage Loans.

(a) The Servicer shall, or shall direct the related Subservicer to, foreclose upon or otherwise comparably convert the ownership of properties securing any Mortgage Loans that come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.06, except that the Servicer shall not, and shall not direct the related Subservicer to, foreclose upon or otherwise comparably convert a Mortgaged Property if there is evidence of toxic waste or other environmental hazards thereon unless the Servicer follows the procedures in Subsection (c) below. In connection with such foreclosure or other conversion, the Servicer in conjunction with the related Subservicer, if any, shall use its best reasonable efforts to preserve REO Property and to realize upon defaulted Mortgage Loans in such manner as to maximize the receipt of principal and interest by the Certificateholders, taking into account, among other things, the timing of foreclosure and the considerations set forth in Subsection 3.13(b). The foregoing is subject to the proviso 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 determines in good faith (i) that such restoration or foreclosure will increase the proceeds of liquidation of the Mortgage Loan to Certificateholders after reimbursement to itself for such expenses and (ii) that such expenses will be recoverable to it either through Liquidation Proceeds (respecting which it shall have priority for purposes of reimbursements from the Collection Account pursuant to Section 3.07) or through Insurance Proceeds (respecting which it shall have similar priority). The Servicer shall be responsible for all costs and expenses constituting Liquidation Expenses incurred by it in any such proceedings; provided, however, that it shall be entitled to reimbursement thereof (as well as its normal servicing compensation) as set forth in Section 3.07. Any income from or other funds (net of any income taxes) generated by REO Property shall be deemed for purposes of this Agreement to be Liquidation Proceeds.

Any subsequent collections with respect to any Liquidated Mortgage Loan shall be deposited to the Collection Account. For purposes of determining the amount of any Liquidation Proceeds or Insurance Proceeds, or other unscheduled collections, the Servicer may take into account any estimated additional Liquidation Expenses expected to be incurred in connection with the related defaulted Mortgage Loan.

In the event that a Mortgage Loan would be properly classified as a Liquidated Mortgage Loan but for the fact that not all MI Insurance Proceeds claimed under the related MI Policy have been received, the Servicer may, from its own funds, make an advance (an “MI Claim Payment Advance”) to the Collection Account in an amount not to exceed the claimed amount of such MI Insurance Proceeds not yet received. The Servicer shall not make any MI Claim Payment Advance with respect to a claim under an MI Policy if an MI Insurer Insolvency

Event has occurred and is continuing with respect to the related MI Insurer. In the event that the MI Claim Payment Advance equals the claimed amount on such MI Policy, then upon the deposit of such MI Claim Payment Advance into the Collection Account the related Mortgage Loan shall be considered a “Liquidated Mortgage Loan.”

In the event that title to any Mortgaged Property is acquired in foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale shall be issued to the Trust Fund and held by the Custodian, who shall hold the same on behalf of Trustee in accordance with the Agreement. Notwithstanding any such acquisition of title and cancellation of the related Mortgage Loan, such Mortgaged Property shall (except as otherwise expressly provided herein) be considered to be an outstanding Mortgage Loan held as an asset of the Issuing Entity until such time as such property shall be sold.

(b) The Servicer shall not acquire any real property (or any personal property incident to such real property) on behalf of the Trust Fund except in connection with a default or reasonably foreseeable default of a Mortgage Loan. In the event that the Servicer acquires any real property (or personal property incident to such real property) on behalf of the Trust Fund in connection with a default or imminent default of a Mortgage Loan, such property shall be disposed of by the Servicer on behalf of the Trust Fund as soon as reasonably practicable, but in no event later than three years after its acquisition on behalf of the Trust Fund.

(c) With respect to any Mortgage Loan as to which the Servicer or a Subservicer has received notice of, or has actual knowledge of, the presence of any toxic or hazardous substance on the Mortgaged Property, the Servicer shall promptly notify the Trustee, and shall act in accordance with any such directions and instructions provided by the Trustee. If the Trustee has not provided directions and instructions to the Servicer in connection with any such Mortgage Loan within 5 days of a request by the Servicer for such directions and instructions, then the Servicer shall take such action as it deems to be in the best economic interest of the Trust Fund (other than proceeding against the Mortgaged Property) and is hereby authorized at such time as it deems appropriate to release such Mortgaged Property from the lien of the related Mortgage. The parties hereto acknowledge that the Servicer shall not obtain on behalf of the Trust Fund or the Trustee a deed as a result or in lieu of foreclosure, and shall not otherwise acquire possession of or title to, or commence any proceedings to acquire possession of or title to, or take any other action with respect to, any Mortgaged Property, if the Trust Fund or the Trustee could reasonably be considered to be a responsible party for any liability arising from the presence of any toxic or hazardous substance on the Mortgaged Property.

Section 3.14 Custodian to Cooperate; Release of Mortgage Files.

(a) Upon payment in full of any Mortgage Loan, the Servicer will immediately notify the Custodian and the Trustee by a certification signed by a Servicing Officer (which certification shall include a statement to the effect that all amounts received in connection with such payment which are required to be deposited in the Collection Account have been so deposited) and shall request delivery to the Servicer or Subservicer, as the case may be, of the Mortgage File. Upon receipt of such certification and Request for Release, the Custodian, on behalf of the Trustee, shall promptly cause to be released the related Mortgage File to the Servicer or Subservicer and the Trustee shall execute and deliver to the Servicer, without

recourse, the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage (furnished by the Servicer), together with the Mortgage Note with written evidence of cancellation thereon.

(b) From time to time as is appropriate, for the servicing or foreclosure of any Mortgage Loan or collection under an insurance policy, the Servicer may deliver to the Trustee and the Custodian a Request for Release signed by a Servicing Officer on behalf of the Servicer in substantially the form attached as Exhibit E hereto. Upon receipt of the Request for Release, the Custodian, on behalf of the Trustee, shall deliver the Mortgage File or any document therein to the Servicer or Subservicer, as the case may be, as bailee for the Trustee.

(c) The Servicer shall cause each Mortgage File or any document therein released pursuant to Subsection 3.14(b) to be returned to the Custodian when the need therefor no longer exists, and in any event within 21 days of the Servicer’s receipt thereof, unless the Mortgage Loan has become a Liquidated Mortgage Loan and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Collection Account or such Mortgage File is being used to pursue foreclosure or other legal proceedings. Prior to return of a Mortgage File or any document to the Custodian, the Servicer, the related insurer or Subservicer to whom such file or document was delivered shall retain such file or document in its respective control as bailee for the Custodian, on behalf of the Trustee, unless the Mortgage File or such document has been delivered to an attorney, or to a public trustee or other public official as required by law, to initiate or pursue legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially, and the Servicer has delivered to the Custodian and the Trustee, a certificate of a Servicing Officer certifying as to the name and address of the Person to which such Mortgage File or such document was delivered and the purpose or purposes of such delivery. If a Mortgage Loan becomes a Liquidated Mortgage Loan, the Custodian, on behalf of the Trustee, shall deliver the Request for Release with respect thereto to the Servicer upon deposit of the related Liquidation Proceeds in the Collection Account.

(d) Upon receipt of written certification of a Servicing Officer, the Trustee shall execute and deliver or cause to be executed and delivered to the Servicer any court pleadings, requests for trustee’s sale or other documents necessary (i) for the foreclosure or trustee’s sale with respect to a Mortgaged Property; (ii) for any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage; (iii) to obtain a deficiency judgment against the Mortgagor; or (iv) to enforce any other rights or remedies provided by the Mortgage Note or Mortgage or otherwise available at law or equity. Each such certification shall include a request that such pleadings or documents be executed by the Trustee and explain the reasons for which the pleadings or documents are required, and certify that the Trustee’s execution and delivery of the pleadings or documents will not invalidate any insurance coverage under the insurance policies or invalidate or otherwise affect the lien of the Mortgage, except for the termination of such a lien upon completion of the foreclosure or trustee’s sale.

Section 3.15 Servicing Compensation.

(a) As compensation for its activities hereunder, the Servicer shall be entitled to receive the Servicing Fee from full payments of accrued interest on each Mortgage Loan. The Servicer shall be solely responsible for paying any and all fees with respect to a Subservicer, and the Trustee and the Trust Fund shall not bear any fees, expenses or other costs directly associated with any Subservicer.

(b) The Servicer may retain additional servicing compensation in the form of late payment charges, to the extent such charges are collected from the related Mortgagors and investment earnings on the Collection Account. The Servicer shall be required to pay all expenses it incurs in connection with servicing activities under this Agreement and shall not be entitled in connection with servicing activities under this Agreement to reimbursement except as provided in this Agreement. Expenses to be paid by the Servicer without reimbursement under this Subsection 3.15(b) shall include payment of the expenses of the accountants retained pursuant to Section 3.17.

Section 3.16 Annual Statements of Compliance.

Within 75 days after December 31 of each year, beginning in 2007, the Servicer at its own expense shall deliver to the Trustee, the Depositor and the Rating Agencies, an Officer’s Certificate of the Servicer (an “Annual Statement of Compliance”) stating, as to the signer 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 officer’s supervision, (ii) to the best of such officer’s knowledge, based on such review, the Servicer has fulfilled its obligations under this Agreement in all material respects for such year, or, if there has been a default in the fulfillment of any such obligation, specifying each such default known to such officer and the nature and status thereof including the steps being taken by the Servicer to remedy such default; (iii) a review of the activities of each Subservicer during the Subservicer’s most recently ended calendar year and its performance under its Subservicing Agreement has been made under such officer’s supervision; and (iv) to the best of the Servicing Officer’s knowledge, based on his review and the certification of an officer of the Subservicer (unless the Servicing Officer has reason to believe that reliance on such certification is not justified), either each Subservicer has performed and fulfilled its duties, responsibilities and obligations under this Agreement and its Subservicing Agreement in all material respects throughout the year, or, if there has been a default in performance or fulfillment of any such duties, responsibilities or obligations, specifying the nature and status of each such default known to the Servicing Officer. Copies of such statements shall be provided by the Servicer to the Certificateholders upon request or by the Trustee at the expense of the Servicer should the Servicer fail to provide such copies. Such Annual Statement of Compliance shall contain no restrictions or limitations on its use. In the event that the Servicer has delegated any servicing responsibilities with respect to the Mortgage Loans to a Subservicer or subcontractor that meets the criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB, the Servicer shall cause the related Subservicer or subcontractor (as the case may be) to deliver a similar Annual Statement of Compliance by that Subservicer or subcontractor to the Trustee, the Depositor and the Rating Agencies as described above as and when required with respect to such servicer. To the extent that the Trustee does not receive any such similar Annual Statement of Compliance from a Subservicer or subcontractor (as the case may be), it shall be entitled to assume no such Subservicer or subcontractor has been used by the Servicer.

Section 3.17 Assessments of Compliance and Attestation Reports.

The Servicer shall service and administer the Mortgage Loans in accordance with all applicable requirements of the Servicing Criteria. Pursuant to Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122 of Regulation AB, each of the Servicer and the Trustee (each, an “Attesting Party”) shall deliver to the Trustee and the Depositor on or before March 15th of each calendar year in which the Issuing Entity is required to file a Form 10-K beginning in 2007, a report regarding such Attesting Party’s assessment of compliance (an “Assessment of Compliance”) with the Servicing Criteria during the preceding calendar year. The Assessment of Compliance, as set forth in Regulation AB, must contain the following:

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

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

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

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

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

On or before March 15th of each calendar year in which the Issuing Entity is required to file a Form 10-K beginning in 2007, each Attesting Party specified in this Section shall furnish to the Trustee and the Depositor a report (an “Attestation Report”) by a registered public accounting firm that attests to, and reports on, the Assessment of Compliance made by the Servicer, as required by Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122(b) of Regulation AB, which Attestation Report must be made in accordance with standards for attestation reports issued or adopted by the Public Company Accounting Oversight Board.

The Servicer or the Trustee, as the case may be, shall cause any Subservicer, and each subcontractor determined by it to be materially “participating in the servicing function” within the meaning of Item 1122 of Regulation AB, to deliver to the Trustee and the Depositor an Assessment of Compliance and Attestation Report as and when provided above along with an indication of what Servicing Criteria are addressed in such assessment.

Notwithstanding the foregoing, as to any Subservicer or subcontractor, an Assessment of Compliance is not required to be delivered unless it is required as part of a Form 10-K with respect to the Issuing Entity.

In addition, the Custodian shall deliver to the Sponsor, the Trustee and the Depositor an Assessment of Compliance and Attestation Report, as and when provided above, which shall at a minimum address each of the Servicing Criteria specified on Exhibit L hereto which are indicated as applicable to a “custodian.”

The Trustee shall have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 10-D, where such failure results from the Trustee’s inability or failure to receive, on a timely basis, as set forth herein, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.

(ii) (A) Within four (4) Business Days after the occurrence of an event requiring disclosure on Form 8-K (each such event, a “Reportable Event”) for so long as the Issuing Entity is subject to the Exchange Act reporting requirements, the Trustee shall file on behalf of the Issuing Entity any Form 8-K prepared by the Depositor, as required by the Exchange Act, provided that the Depositor shall file the initial Form 8-K in connection with the issuance of the Certificates; provided further, that the Trustee shall only be responsible for filing such Form 8-K if the Trustee has been notified by the Depositor of the necessity therefore and provided with the disclosure to be included therein. Any disclosure or information related to a Reportable Event or that is otherwise required to be included on Form 8-K (“Form 8-K Disclosure Information”) shall be prepared by the Depositor.

The Trustee shall have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare and/or timely file such Form 10-K, where such failure results from the Trustee’s inability or failure to receive, on a timely basis, as set forth herein, any information from any other party hereto needed to prepare, arrange for execution or file such Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

(D) Each Form 10-K shall include a certification (the “Xxxxxxxx-Xxxxx Certification”), required to be included therewith pursuant to the Xxxxxxxx-Xxxxx Act. The Servicer and the Trustee, shall and the Servicer shall cause any Subservicer or subcontractor engaged by it to, provide to the Person who signs the Xxxxxxxx-Xxxxx Certification (the “Certifying Person”), by March 15 of each year in which the Issuing Entity is subject to the reporting requirements of the Exchange Act, a certification (each, a “Back-Up Certification”), in the form attached hereto as Exhibit N-2, upon which the Certifying Person, the entity for which the Certifying Person acts as an officer, and such entity’s officers, directors and Affiliates (collectively with the Certifying Person, “Certification Parties”) can reasonably rely. The senior officer of the Servicer shall serve as the Certifying Person on behalf of the Issuing Entity. Such officer of the Certifying Person can be contacted as set forth in Section 12.06. In the event the Trustee is terminated or resigns pursuant to the terms of this Agreement, the Trustee shall provide a Back-Up Certification to the Certifying Person pursuant to this Section 3.18(a)(iii) with respect to the period of time it was subject to this Agreement.

(iv) With respect to any Additional Form 10-D Disclosure or Additional From 10-K Disclosure (collectively, the “Additional Disclosure”) relating to the Trust Fund, the Trustee’s obligation to include such Additional Information in the applicable Exchange Act report is subject to receipt from the entity that is indicated in Exhibit M as the responsible party for providing that information, if other than the Trustee, as and when required as described in Section 3.18(a)(i) through (iii) above.

Each of the Trustee, Servicer, Sponsor, and Depositor hereby agree to notify and provide to the extent known to the Depositor all 8-K Additional Disclosure relating to the Trust Fund, with respect to which such party is indicated in Exhibit M as the responsible party for providing that information.

(vi) (A) On or prior to January 30 of the first year in which the Trustee is able to do so under applicable law, the Trustee shall file a Form 15 relating to the automatic suspension of reporting in respect of the Issuing Entity under the Exchange Act. The Trustee will promptly notify the Depositor, the Servicer and the Hedge Counterparties after filing Form 15.

(B) In the event that the Trustee is unable to timely file with the Commission all or any required portion of any Form 10-D or 10-K required to be filed by this Agreement because required disclosure information was either not delivered to it or delivered to it after the delivery deadlines set forth in this Agreement or for any other reason, the Trustee will immediately notify the Depositor and the Servicer. In the case of Form 10-D and 10-K, the Depositor, Servicer and Trustee will cooperate to prepare and file a Form 12b-25 and a 10-D/A and 10-K/A as applicable, pursuant to Rule 12b-25 of the Exchange Act. In the case of Form 8-K, the Depositor will, upon receipt of all required Form 8-K Disclosure Information provide such Form 8-K Disclosure Information to the Trustee for inclusion on the next Form 10-D. In the event that any previously filed Form 10-D or 10-K needs to be amended, the Trustee (to the extent of actual knowledge) will notify the Depositor and the Servicer and such parties will cooperate to prepare any necessary 10-D/A or 10-K/A. Any Form 15, Form 12b-25 or any amendment to Form 8-K, 10-D or 10-K shall be signed by a senior officer of the Servicer. The Depositor and Servicer acknowledge that the performance by the Trustee of its duties under this Section 3.18(a)(v) related to the timely preparation and filing of Form 15, or any amendment to Form 10-D or 10-K, is contingent upon the Servicer and the Depositor performing their duties under this Section. The Trustee shall have no liability for any loss, expense, damage, claim arising out of or with respect to any failure to properly prepare and/or timely file any such Form 15 or any amendments to Forms 10-D or 10-K, where such failure results from the Trustee’s inability or failure to receive, on a timely basis, any information from any other party hereto needed to prepare, arrange for execution or file such Form 15 or any amendments to Forms 8-K, 10-D or 10-K, not resulting from its own negligence, bad faith or willful misconduct. The Depositor shall be responsible for preparing and filing any required Form 12b-25 and the Trustee shall have no obligations with respect thereto.

The Depositor agrees to promptly furnish to the Trustee, from time to time upon request, such further information, reports and financial statements within its control related to this Agreement, the Mortgage Loans as is necessary for the preparation and filing of all required reports with the Commission. The Trustee shall have no responsibility to file any items other than those specified in this Section 3.18; provided, however, the Trustee will cooperate with the Depositor in connection with any additional filings with respect to the Issuing Entity as the Depositor deems necessary under the Exchange Act. Copies of all reports filed by the Trustee under the Exchange Act shall be sent to the Depositor as set forth in Section 12.06.

(b) In connection with the filing of any 10-K hereunder, the Trustee shall sign a certification (a “Form of Back-Up Certification to Form 10-K Certificate,” substantially in the form attached hereto as Exhibit N-2) for the Depositor regarding certain aspects of the Form 10-K certification signed by the Depositor, provided, however, that the Trustee shall not be required to undertake an analysis of any accountant’s report attached as an exhibit to the Form 10-K.

(c) Notwithstanding anything to the contrary contained in this Agreement, the Servicer shall indemnify the Depositor and the Trustee and any director, officer, employee or

agent of the Depositor or the Trustee and hold them harmless against any and all claims, losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments, and any other costs, fees and expenses that any of them may sustain in any way related to any failure by the Servicer or any Subservicer engaged by the Servicer or any Subcontractor utilized by the Servicer to deliver any information, report, certification or accountants’ letter when and as required under this Section, including without limitation any failure by the Servicer to identify any Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB. If such indemnification is unavailable or insufficient to hold harmless any Person entitled to indemnification thereunder, then the Servicer shall contribute to the amount paid or payable to the Person entitled to indemnification as a result of the losses, claims, damages or liabilities of such Person in such proportion as is appropriate to reflect the relative fault of such Person on the one hand and the Servicer, on the other, in connection with the Servicer’s obligations pursuant to this Section. This Section shall survive the termination of this Agreement or the earlier resignation or removal of the Servicer.

Section 3.19 Optional Purchase of Defaulted Mortgage Loans.

Subject to the limitations set forth in Section 10.02 hereof, the Servicer shall have the right, but not the obligation, to purchase any Mortgage Loan which becomes 90 days or more delinquent at a purchase price equal to the Repurchase Price (a) within 29 days after the date the Mortgage Loan becomes 90 days delinquent or (b) on the date the Servicer liquidates the related Mortgaged Property. The procedure for such purchase shall be the same as for a repurchase made by the Sponsor under the Purchase Agreement. With respect to any Mortgage Loans being purchased pursuant to this Section 3.19, the Servicer shall purchase the most delinquent Mortgage Loans before purchasing other less delinquent Mortgage Loans. The Servicer or the related Subservicer may purchase a Mortgage Loan at the Repurchase Price when the Servicer requires acceleration of the Mortgage Loan, but only if the Servicer is satisfied, as evidenced by a certification from a Servicing Officer delivered to the Trustee, that such Mortgage Loan is in default or default is reasonably foreseeable.

Section 3.20 Information Required by the Internal Revenue Service Generally and Reports of Foreclosures and Abandonments of Mortgaged Property.

The Servicer shall prepare and deliver all federal and state information reports when and as required by all applicable state and federal income tax laws. In particular, with respect to the requirement under Section 6050J of the Code to the effect that the Servicer or Subservicer shall make reports of foreclosures and abandonments of any mortgaged property, the Servicer or Subservicer shall file reports relating to each instance occurring during the previous calendar year in which the Servicer (i) acquires an interest in any Mortgaged Property through foreclosure or other comparable conversion in full or partial satisfaction of a Mortgage Loan, or (ii) knows or has reason to know that any Mortgaged Property has been abandoned. The reports from the Servicer or Subservicer shall be in form and substance sufficient to meet the reporting requirements imposed by Section 6050J, Section 6050H (reports relating to mortgage interest received) and Section 6050P of the Code (reports relating to cancellation of indebtedness).

Section 3.21 [Reserved].

Section 3.22 [Reserved].

Section 3.23 Servicing and Administration of the MI Policies.

(a) The Servicer shall take all such actions on behalf of the Trustee as are necessary to service, maintain and administer the MI Policies and to perform the Trustee’s obligations and enforce the Trustee’s rights under the MI Policies, which actions shall conform to the standards of an institution prudently administering MI Policies for its own account. Except as expressly set forth herein, the Servicer shall have full authority on behalf of the Issuing Entity to do anything it reasonably deems appropriate or desirable in connection with the servicing, maintenance and administration of the MI Policies. The Servicer shall make its best reasonable efforts to file all insured claims under the MI Policies and collect from the MI Insurer all Insurance Proceeds due to the Trustee under the MI Policies. The Servicer shall not take, or permit any Subservicer to take, any action which would result in non-coverage under any applicable MI Policy of any loss which, but for the actions of the Servicer or Subservicer, would have been covered thereunder. To the extent coverage is available, the Servicer shall keep or cause to be kept in full force and effect each such MI Policy for the life of the Mortgage Loan; provided, however, that if a MI Insurer Insolvency Event has occurred and is continuing, the Servicer may terminate the MI Policy on any Mortgage Loan that is not then past due. The Servicer shall cooperate with the MI Insurer and shall use its best efforts to furnish all reasonable aid, evidence and information in the possession of the Servicer or to which the Servicer has access with respect to any Mortgage Loan.

(b) The Servicer shall deposit into the Collection Account pursuant to Section 3.06(d)(v) hereof all MI Insurance Proceeds received from the MI Insurer under the terms of the MI Policies. The Servicer shall withdraw from the Collection Account and pay to the MI Insurer pursuant to Section 3.07(a)(xii) hereof, the monthly MI Premiums due to the MI Insurer in accordance with the terms of the MI Insurance Agreements. In the event that the Trustee has actual knowledge that any MI Premiums have in fact not been paid, the Trustee shall distribute such amounts (in such amounts as specified by the MI Insurer in writing) to the MI Insurer from the Interest Remittance Amount for the related Mortgage Loans, at the same level of priority as the Trustee Fee.

(c) Notwithstanding the provisions of Subsection 3.23(a) and (b), the Servicer shall not take any action in regard to the MI Policies inconsistent with the interests of the Trustee or the Certificateholders or with the rights and interests of the Trustee or the Certificateholders under this Agreement; provided, however, that payments of the monthly MI Premiums to the MI Insurer pursuant to Subsection 3.23(b) above and Section 3.07(a)(xii) hereof shall be deemed not to be inconsistent with such interests.

(d) The Trustee shall furnish the Servicer with any powers of attorney in the form of Exhibit P and other documents in form as provided to it necessary or appropriate to enable the Servicer to service and administer the MI Policies; provided, however, that the Trustee shall not be liable for the actions of, or the use or misuse by, the Servicer under such powers of attorney.

(e) If at any time during the term of this Agreement, a MI Insurer Insolvency Event has occurred and is continuing, the Servicer agrees to review, not less often than monthly, the financial condition of the related MI Insurer with a view towards determining whether recoveries under the MI Policy are jeopardized for reasons related to the financial condition of the related MI Insurer. In such event, the Servicer may obtain an additional MI Policy or a replacement MI Policy, the MI Premiums on which would be paid by the Servicer from the Collection Account pursuant to Section 3.07(a)(xii) hereof.

(f) The Servicer shall comply with all other terms, conditions and obligations set forth in the MI Policies.

Section 3.24 Determination Date Reports.

On the second Business Day following each Determination Date (the “Servicer Reporting Date”), the Servicer shall deliver to the Trustee a report, prepared as of the close of business on the Determination Date (the “Determination Date Report”), and shall forward to the Trustee in the form of computer readable electromagnetic tape or disk a copy of such report in a format acceptable to the Trustee. The Determination Date Report and any written information supplemental thereto shall include such information with respect to the Mortgage Loans that is reasonably available to the Servicer and that is required by the Trustee for purposes of making the calculations and providing the reports referred to in this Agreement, as set forth in written specifications or guidelines issued by the Trustee from time to time. Such information shall include the aggregate amounts required to be withdrawn from the Collection Account and deposited into the Distribution Account pursuant to Section 3.07. Such information shall also include (a) the number of Mortgage Loans that prepaid in the previous month; (b) the loan balance of each such Mortgage Loan; (c) whether a prepayment penalty was applied to such Mortgage Loan; and (d) the amount of prepayment penalty with respect to each such Mortgage Loan. The Servicer agrees to cooperate with the Trustee in providing all information as is reasonably requested by the Trustee to prepare the reports required under the Agreement.

The determination by the Servicer of such amounts shall, in the absence of obvious error, be presumptively deemed to be correct for all purposes hereunder and the Trustee shall be fully protected in relying upon the same without any independent check or verification.

Section 3.25 Advances.

If any Monthly Payment (together with any advances from the Subservicers) on a Mortgage Loan that was due on the immediately preceding Due Date and delinquent on the Determination Date is delinquent other than as a result of application of the Relief Act, the Servicer will deposit in the Collection Account not later than the Servicer Remittance Date immediately preceding the related Distribution Date an amount equal to such deficiency net of the related Servicing Fee for such Mortgage Loan, except to the extent the Servicer determines any such advance to be nonrecoverable from Liquidation Proceeds, Insurance Proceeds or future payments on such Mortgage Loan. Subject to the foregoing and in the absence of such a determination, the Servicer shall continue to make such advances through the date that the related Mortgaged Property has, in the judgment of the Servicer, been completely liquidated.

The Servicer may fund an Advance from its own corporate funds, advances made by any Subservicer or funds held in the Collection Account for future payment or withdrawal.

Advances made from funds held in the Collection Account may be made by the Servicer from subsequent collections of principal and interest received on other Mortgage Loans and deposited into the Collection Account. Advances made from the Collection Account are not limited to subsequent collections of principal and interest received on the delinquent Mortgage Loan with respect to which an Advance is made. If on the Servicer Remittance Date prior to any Distribution Date funds in the Collection Account are less than the amount required to be paid to the Certificateholders on such Distribution Date, then the Servicer shall deposit its own funds into the Distribution Account in the amount of the lesser of (i) any unreimbursed Advances previously made by the Servicer with funds held in the Collection Account or (ii) the shortfall in the Collection Account, provided, however, that in no event shall the Servicer deposit into the Collection Account an amount that is less than any shortfall in the Collection Account attributable to delinquent payments on Mortgage Loans which the Servicer deems to be recoverable and which has not been covered by an Advance from the Servicer’s own corporate funds or any Subservicer’s funds. If applicable, on the Servicer Remittance Date preceding each Distribution Date, the Servicer shall present an Officers’ Certificate to the Trustee (i) stating that the Servicer elects not to make an Advance in a stated amount and (ii) detailing the reason it deems the advance to be nonrecoverable.

Section 3.26 Compensating Interest Payments.

The Servicer shall deposit in the Collection Account not later than the Servicer Remittance Date preceding the Distribution Date an amount equal to the Compensating Interest related to the related Determination Date. The Servicer shall not be entitled to any reimbursement of any Compensating Interest payment.

Section 3.27 Advance Facility.

(a) The Servicer on behalf of the Trust Fund, is hereby authorized to enter into a facility (such an arrangement, an “Advance Facility”) with any Person which provides that such Person (an “Advancing Person”) may fund Advances and/or Servicing Advances under this Agreement, although no such facility shall reduce or otherwise affect the Servicer’s obligation to fund such Advances and/or Servicing Advances. No consent of the Trustee, Certificateholders or any other party shall be required before the Servicer may enter into an Advance Facility nor shall the Trustee or the Certificateholders be a third party beneficiary of any obligation of an Advancing Person to the Servicer. If the Servicer enters into an Advance Facility, the Servicer and the related Advancing Person shall deliver to the Trustee at the address set forth in Section 12.06 hereof a written notice (an “Advance Facility Notice”) (in the form attached hereto as Exhibit K), stating (a) the identity of the Advancing Person and (b) the identity of the Person (the “Servicer’s Assignee”) that will, subject to Section 3.27(b) hereof, have the right to make withdrawals from the Collection Account pursuant to Section 3.07 hereof to reimburse previously unreimbursed Advances and/or Servicing Advances (“Advance Reimbursement Amounts”). If the Servicer enters into such an Advance Facility pursuant to this Section 3.27, the Trustee shall execute the acknowledgment of the Advance Facility Notice, as prepared by the Servicer confirming its receipt of written notice of the existence of such Advance Facility. To

the extent that an Advancing Person purchases or funds any Advance or any Servicing Advance and provides the Trustee with written notice (in the form attached hereto as Exhibit K) acknowledged by the Servicer that such Advancing Person is entitled to reimbursement directly from the Trustee pursuant to the terms of the Advance Facility, such Advancing Person shall be entitled to receive reimbursement pursuant to this Agreement for such amount to the extent provided in Section 3.27(b). Such notice from the Advancing Person must specify the amount of the reimbursement, the Section of this Agreement that permits the applicable Advance or Servicing Advance to be reimbursed, the section(s) of the Advance Facility that entitle the Advancing Person to request reimbursement from the Trustee, on behalf of the Trust Fund, rather than the Servicer, the Advancing Person’s wire transfer instructions, and include the Servicer’s acknowledgment thereto or proof of an Event of Default under the Advance Facility. The Trustee shall have no duty or liability with respect to any calculation of any reimbursement to be paid to an Advancing Person and shall be entitled to rely without independent investigation on the Advancing Person’s notice provided pursuant to this Section 3.27. An Advancing Person whose obligations hereunder are limited to the funding of Advances and/or Servicing Advances shall not be required to meet the qualifications of a Sub-Servicer pursuant to Section 6.06 hereof.

(b) 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 Collection Account pursuant to Section 3.07 of this Agreement and shall not otherwise be entitled to make withdrawals or receive amounts that shall be deposited in the Distribution Account, 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 Servicer’s Assignee, as applicable, shall be entitled pursuant to Section 3.07 hereof. An Advance Facility may be terminated by the joint written direction of the Servicer and the related Advancing Person. Written notice of such termination shall be delivered to the Trustee in the manner set forth in Section 12.06 hereof. None of the Depositor 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 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 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 Person, except to the extent that such claim, loss, liability or damage resulted from or arose out of negligence, recklessness or willful misconduct on the part of the Depositor, the Trustee or any successor Servicer, as the case may be, or failure by the successor Servicer or the Trustee, as the case may be, to remit funds as required by this Agreement or the commission of an act or omission to act by the successor Servicer or the Trustee, as the case may be, and the passage of any applicable cure or grace period, such that an Event of Default under this Agreement occurs or such entity is subject to termination for cause under this Agreement. 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 Person. The successor Servicer shall be entitled to rely on any such information provided by the predecessor Servicer, and the successor Servicer shall not be liable for any errors in such information.

(c) If an Advancing Person is entitled to reimbursement for any particular Advance or Servicing Advance as set forth in Section 3.27(a), then the Servicer shall not be permitted to reimburse itself therefor under Section 3.07, but instead the Servicer shall include such amounts in the applicable remittance to the Trustee made pursuant to Section 3.06(d) to the extent of amounts on deposit in the Collection Account on the related Servicer Remittance Date. The Trustee is hereby authorized to pay to an Advancing Person reimbursements for Advances and Servicing Advances from the Distribution Account to the same extent the Servicer would have been permitted to reimburse itself for such Advances and/or Servicing Advances in accordance with Section 3.07, had the Servicer made such Advance or Servicing Advance.

(d) All Advances and Servicing Advances made pursuant to the terms of this Agreement shall be deemed made and shall be reimbursed on a “first in first out” (FIFO) 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 such predecessor Servicer or its related Advancing Person in error, then such 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 pursuant to Section 3.07 for all Advances and/or Servicing Advances funded by the Servicer to the extent the related Advance reimbursement amounts have not been assigned, sold or pledged to such Advancing Person or Servicer’s Assignee.

(e) In the event the Servicer is terminated pursuant to Section 7.01, the Advancing Person shall succeed to the terminated Servicer’s right of reimbursement set forth in Section 7.02 to the extent of such Advancing Person’s financing of Advances or Servicing Advances hereunder then remaining unreimbursed.

(f) Any amendment to this Section 3.27 or to any other provision of this Agreement that may be necessary or appropriate to effect the terms of an Advance Facility as described generally in this Section 3.27, including amendments to add provisions relating to a successor Servicer, may be entered into by the Trustee, the Depositor and the Servicer without the consent of any Certificateholder, provided such amendment complies with Section 12.01 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, sold and/or pledged to an Advancing Person under any Advance Facility are obligations owed to the Servicer payable only from the cash flows and proceeds received under this Agreement for reimbursement of Advances and/or Servicing Advances only to the extent provided herein, and the Trustee and the Trust Fund are not, as a result of the existence of any Advance Facility, obligated or liable to repay any Advances and/or Servicing Advances financed by the Advancing Person; (b) the Servicer will be responsible for remitting to the Advancing Person the applicable amounts collected by it as reimbursement for Advances and/or Servicing Advances purchased or funded by the Advancing Person, subject to the provisions of this Agreement; and (c) the Trustee shall not have any responsibility to track or monitor the administration of the financing arrangement between the Servicer and any Advancing Person.

Section 3.28 Servicer Rights Facility.

The Servicing Rights Owner is hereby authorized to finance, pledge and/or assign any or all of its right, title and interest in, to and under this Agreement to one or more lenders (each, a “Servicing Rights Pledgee”) selected by the Servicing Rights Owner. The Trustee and the Depositor hereby (i) consent to any such financing, pledge and/or assignment (without the need for the delivery of any notice or other communication to the Trustee or the Depositor, or for the execution by the Trustee or the Depositor of any agreement or other document or instrument, other than this Agreement), and (ii) agree that upon delivery by the Servicing Rights Pledgee to the Trustee of a letter signed by the Servicing Rights Pledgee (without further need for the delivery of any notice or other communication to the Trustee or the Depositor, or for the execution by the Trustee or the Depositor of any agreement or other document or instrument in addition to this Agreement), the Trustee shall appoint the Servicing Rights Pledgee or its designee as successor Servicer upon termination of the Servicer, provided that at the time of such appointment, the Servicing Rights Pledgee or such designee meets the requirements of a successor Servicer pursuant to Section 7.02 and agrees to be subject to the terms of this Agreement. For the avoidance of doubt, the Servicing Rights Pledgee or its designee (as the case may be) shall not be otherwise required to satisfy any other eligibility requirements of a successor Servicer pursuant to Section 6.04.

All Realized Losses on the Mortgage Loans shall be allocated by the Trustee on each Distribution Date as follows: first, to amounts of Excess Cashflow, second, to the Overcollateralization Amount, third, to the Class M-12 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fourth, to the Class M-11 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fifth, to the Class M-10 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; sixth, to the Class M-9 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; seventh, to the Class M-8 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; eighth, to the Class M-7 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; ninth, to the Class M-6 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; tenth, to the Class M-5 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; eleventh, to the Class M-44 Certificates; twelfth, to the Class M-3 Certificates, until the Certificate Principal Balance of each such Class has been reduced to zero; thirteenth, to the Class M-2 Certificates, until the Certificate Principal Balance of each such Class has been reduced to zero; and fourteenth, to the Class M-1 Certificates, until the Certificate Principal Balance of each such Class has been reduced to zero. All Realized Losses to be allocated to the Certificate Principal Balances of all Classes 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 of 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. In no event shall Realized Losses be allocated to the Class A-1A Certificates, the Group II Certificates or the Class I Certificates.

Any allocation of Realized Losses to a Mezzanine Certificate on any Distribution Date shall be made by reducing the Certificate Principal Balance thereof by the amount so allocated. Any Subsequent Recoveries will be allocated to the Overcollateralization Amount and Mezzanine Certificates in the reverse order of the Realized Loss allocation set forth in the preceding paragraph, to the extent of the Realized Loss allocated to each related Certificate (or in the case of the Overcollateralization Amount, to the extent of the Realized Loss allocated to such Overcollateralization Amount).

THE CERTIFICATES

Section 5.01 The Certificates.

Each of the Class A Certificates, the Mezzanine Certificates, the Class M-7 DSI Certificates, the Class M-10 DSI Certificates, the Class M-11 DSI Certificates, the Class M-12 DSI Certificates, the Class C Certificates, the Class I Certificates and the Residual Certificates shall be substantially in the forms annexed hereto as exhibits, and shall, on original issue, be executed, authenticated and delivered by the Trustee to or upon the order of the Depositor concurrently with the sale and assignment to the Issuing Entity of the Trust Fund. The Class A Certificates and Mezzanine Certificates shall be initially evidenced by one or more Certificates representing a Percentage Interest with a minimum dollar denomination of $25,000 and integral dollar multiples of $1,000 in excess thereof, with a minimum investment of $100,000 (if the Certificates are Book-Entry Certificates), except that one Certificate of each such Class of Certificates may be in a different denomination so that the sum of the denominations of all outstanding Certificates of such Class shall equal the Certificate Principal Balance of such Class on the Closing Date. The Class M-7 DSI Certificates, the Class M-10 DSI Certificates, the Class M-11 DSI Certificates, the Class M-12 DSI Certificates, the Class C Certificates, the Class I Certificates and the Residual Certificates are issuable in any Percentage Interests; provided, however, that the sum of all such percentages for each such Class totals 100% and no more than ten Certificates of each Class may be issued.

The Certificates shall be executed on behalf of the Issuing Entity by manual or facsimile signature on behalf of the Trustee by a Responsible Officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Trustee shall bind the Issuing Entity, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificate. No Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose, unless such Certificate shall have been manually authenticated by the Trustee substantially in the form provided for herein, and such authentication upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. Subject to Section 5.02(c), the Class A Certificates and Mezzanine Certificates shall be Book-Entry Certificates. The other Classes of Certificates shall be Definitive Certificates.

Section 5.02 Registration of Transfer and Exchange of Certificates.

(a) The Certificate Registrar shall cause to be kept at the Corporate Trust Office a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. The Trustee shall initially serve as Certificate Registrar for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided.

Upon surrender for registration of transfer of any Certificate at the office designated in the definition of “Corporate Trust Office” maintained for such purpose pursuant to the foregoing paragraph and, in the case of a Residual Certificate, upon satisfaction of the conditions set forth below, the Trustee on behalf of the Issuing Entity shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same aggregate Percentage Interest.

At the option of the Certificateholders, Certificates may be exchanged for other Certificates in authorized denominations and the same aggregate Percentage Interests, upon surrender of the Certificates to be exchanged at such designated office. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute on behalf of the Issuing Entity and authenticate and deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall (if so required by the Trustee or the Certificate Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer satisfactory to the Trustee and the Certificate Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing.

(b) Except as provided in paragraph (c) below, the Book-Entry Certificates shall at all times remain registered in the name of the Depository or its nominee and at all times: (i) registration of such Certificates may not be transferred by the Trustee except to another Depository; (ii) the Depository shall maintain book-entry records with respect to the Certificate Owners and with respect to ownership and transfers of such Certificates; (iii) ownership and transfers of registration of such Certificates on the books of the Depository shall be governed by applicable rules established by the Depository; (iv) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants; (v) the Trustee shall for all purposes deal with the Depository as representative of the Certificate Owners of the Certificates for purposes of exercising the rights of Holders under this Agreement, and requests and directions for and votes of such representative shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; (vi) the Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the Depository Participants with respect to indirect participating firms and Persons shown on the books of such indirect participating firms as direct or indirect Certificate Owners; and (vii) the direct participants of the Depository shall have no rights under this Agreement under or with respect to any of the Certificates held on their behalf by the

Depository, and the Depository may be treated by the Trustee, the Trustee and its agents, employees, officers and directors as the absolute owner of the Certificates for all purposes whatsoever.

All transfers by Certificate Owners of Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owners. Each Depository Participant shall only transfer Book-Entry Certificates of Certificate Owners that it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures. The parties hereto are hereby authorized to execute a Letter of Representations with the Depository or take such other action as may be necessary or desirable to register a Book-Entry Certificate to the Depository. In the event of any conflict between the terms of any such Letter of Representation and this Agreement, the terms of this Agreement shall control.

(c) If (i)(x) the Depository or the Depositor advises the Trustee in writing that the Depository is no longer willing or able to discharge properly its responsibilities as Depository and (y) the Depositor is unable to locate a qualified successor, or (ii) after the occurrence of a Servicing Default, the Certificate Owners of the Book-Entry Certificates representing not less than 51% of the Voting Rights advise the Trustee and Depository through the Financial Intermediaries and the Depository Participants in writing that the continuation of a book-entry system through the Depository to the exclusion of definitive, fully registered certificates (“Definitive Certificates”) to Certificate Owners is no longer in the best interests of the Certificate Owners. Upon surrender to the Certificate Registrar of the Book-Entry Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Trustee shall, at the Sponsor’s expense, execute on behalf of the Issuing Entity and authenticate the Definitive Certificates. Neither the Depositor nor the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates, the Trustee, the Certificate Registrar, the Servicer, any Paying Agent and the Depositor shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder.

(d) No transfer, sale, pledge or other disposition of any Class M-10 Certificate, Class M-11 Certificate, Class M-12 Certificate, Class N Certificate, Class DSI Certificate, Class CA Certificate, Class CB Certificate or Residual Certificate shall be made unless such disposition is exempt from the registration requirements of the Securities Act of 1933, as amended (the “1933 Act”), and any applicable state securities laws or is made in accordance with the 1933 Act and laws. In the event of any such transfer, except with respect to transfers of any Class M-10 Certificate, Class M-11 Certificate, Class M-12 Certificate, Class N Certificate, Class DSI Certificate, Class CA Certificate, Class CB Certificate or Residual Certificates by or to the Depositor by or to NCFLLC by or to NCFC, or by or to NCFC by or to NCFLLC by or to Greenwich Capital Financial Products, Inc., Wachovia Investment Holdings, LLC, or Newport Funding Corp., unless (i) such transfer is made in reliance upon Rule 144A under the 1933 Act and an investment letter, in substantially the form attached hereto as Exhibit G, is delivered by the Transferee to the Trustee) or (ii) a written Opinion of Counsel (which may be in-house counsel) acceptable to and in form and substance reasonably satisfactory to the Trustee and the Depositor is delivered to them stating that such transfer may be made pursuant to (x) the 1933 Act, or an exemption thereto, describing the applicable provision or exemption and

the basis therefore, and (y) the Investment Company Act of 1940, or an exemption thereto, describing the applicable provision or exemption and the basis therefore, which Opinion of Counsel shall not be an expense of the Trustee or the Depositor. The Holder of a Class M-10 Certificate, Class M-11 Certificate, Class M-12 Certificate, Class N Certificate, Class DSI Certificate, Class CA Certificate, Class CB Certificate or Residual Certificate desiring to effect such transfer shall indemnify and hold harmless the Trustee and the Depositor 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.

The Class I Certificates shall be registered in the name of the Supplemental Interest Trust and shall not be transferable.

No transfer of a Class M-7 Certificate, Class M-10 Certificate, Class M-11 Certificate, Class M-12 Certificate, Class N Certificate, Class DSI Certificate, Class CA Certificate, Class CB Certificate or Residual Certificate or any interest therein shall be made to any Plan or to any Person acting, directly or indirectly, on behalf of any such Plan or acquiring such Certificates with “plan assets” of a Plan within the meaning of the Department of Labor regulation promulgated at 29 C.F.R. § 2510.3-101 or otherwise (“Plan Assets”). Each Person who acquires any Ownership Interest in such Classes of Certificates shall be deemed, by the acceptance or acquisition of such Ownership Interest, to represent that it is not a Plan and is not acting, directly or indirectly, on behalf of a Plan or acquiring such Ownership Interest with Plan Assets. The foregoing restrictions shall not apply to the transfer of any Class M-7 Certificate, Class M-10 Certificate or Class M-11 Certificate that has been sold pursuant to a Qualified Underwriting, provided such transfer satisfies the other conditions under an Underwriter Exemption. The foregoing restrictions shall not apply to the transfer of any Class M-12 Certificate that has been sold pursuant to a Qualified Underwriting, provided such transfer is to an “insurance company general account” (within the meaning of PTCE 95-60) and the conditions set forth in Sections I and III of PTCE 95-60 have been satisfied.

Reallocations are not, in and of themselves, “transfers, sales, pledges or other dispositions” of the related Classes requiring any action pursuant to this Section 5.02.

The Depositor agrees to provide, upon request of any holder of a private Certificate or of any prospective purchaser of a private Certificate designated by such holder, at or prior to the time of sale, reasonably current information concerning the Issuing Entity and the Mortgage Loans, as more specifically detailed pursuant to Rule 144A(d) under the 1933 Act.

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 to have irrevocably appointed the Depositor or its designee as its attorney-in-fact to negotiate the terms of any mandatory sale under clause (v) below and to execute all instruments of transfer and to do all other things necessary in connection with any such sale, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

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

(ii) No Person shall acquire an Ownership Interest in a Residual Certificate unless such Ownership Interest is a pro-rata undivided interest.

(iii) In connection with any proposed transfer of any Ownership Interest in a Residual Certificate, the Trustee shall as a condition to registration of the transfer, require delivery to it, in form and substance satisfactory to it, of each of the following:

(A) an affidavit in the form of Exhibit H hereto from the proposed transferee to the effect that such transferee is a Permitted Transferee and 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 who is not a Permitted Transferee; and

(B) an affidavit in the form of Exhibit I hereto from the proposed transferor to the effect that no purpose of the transfer is to impede the assessment or collection of any tax.

(iv) Any attempted or purported transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section shall be absolutely null and void and shall vest no rights in the purported transferee. If any purported transferee shall, in violation of the provisions of this Section, become a Holder of a Residual Certificate, then the prior Holder of such Residual Certificate that is a Permitted Transferee shall, upon discovery that the registration of transfer of such Residual Certificate was not in fact permitted by this Section, be restored to all rights as Holder thereof retroactive to the date of registration of transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of transfer of a Residual Certificate that is in fact not permitted by this Section or for making any distributions due on such Residual Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Trustee received the documents specified in clause (iii). The Trustee shall be entitled to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time such distributions were made all distributions made on such Residual Certificate. Any such distributions so recovered by the Trustee shall be distributed and delivered by the Trustee to the prior Holder of such Residual Certificate that is a Permitted Transferee.

(v) If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section, then the Trustee shall have the right but not the obligation, without notice to the Holder of such Residual Certificate or any other Person having an Ownership Interest therein, to notify the Depositor to arrange for the sale of such Residual Certificate. The proceeds of such sale, net of commissions (which may include commissions payable to the Depositor or its affiliates in connection with

such sale), expenses and taxes due, if any, will be remitted by the Trustee to the previous Holder of such Residual Certificate that is a Permitted Transferee, except that in the event that the Trustee determines that the Holder of such Residual Certificate may be liable for any amount due under this Section or any other provisions of this Agreement, the Trustee may withhold a corresponding amount from such remittance as security for such claim. The terms and conditions of any sale under this clause (v) shall be determined in the sole discretion of the Trustee and the Depositor and neither of them shall be liable to any Person having an Ownership Interest in a Residual Certificate as a result of its exercise of such discretion.

(vi) If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section, then the Trustee upon receipt of reasonable compensation will provide to the Internal Revenue Service, and to the persons specified in Sections 860E(e)(3) and (6) of the Code, information needed to compute the tax imposed under Section 860E(e) of the Code on transfers of residual interests to disqualified organizations.

The foregoing provisions of this Section shall cease to apply to transfers occurring on or after the date on which there shall have been delivered to the Trustee, in form and substance satisfactory to the Trustee, (i) written notification from each Rating Agency that the removal of the restrictions on Transfer set forth in this Section will not cause such Rating Agency to downgrade its rating of the Certificates and (ii) an Opinion of Counsel to the effect that such removal will not cause any REMIC created hereunder to fail to qualify as a REMIC.

(e) No service charge shall be made for any registration of transfer or exchange of Certificates of any Class, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

All Certificates surrendered for registration of transfer or exchange shall be cancelled by the Certificate Registrar and disposed of pursuant to its standard procedures.

Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

If (i) any mutilated Certificate is surrendered to the Certificate Registrar or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (ii) there is delivered to the Trustee, the Depositor and the Certificate Registrar such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee or the Certificate Registrar that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute on behalf of the Issuing Entity, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and Percentage Interest. Upon the issuance of any new Certificate under this Section, the Trustee or the Certificate Registrar 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 Trustee and the

Certificate Registrar) in connection therewith. Any duplicate Certificate issued pursuant to this Section, shall constitute complete and indefeasible evidence of ownership in the Issuing Entity, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 5.04 Persons Deemed Owners.

The Servicer, the Depositor, the Trustee, the Certificate Registrar, any Paying Agent and any agent of the Servicer, the Depositor, the Trustee, the Certificate Registrar or any Paying Agent may treat the Person, including a Depository, in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 4.01 and for all other purposes whatsoever, and none of the Servicer, the Issuing Entity, the Trustee nor any agent of any of them shall be affected by notice to the contrary.

Section 5.05 Appointment of Paying Agent.

(a) The Paying Agent shall make distributions to Certificateholders from the Distribution Account pursuant to Section 4.01 and shall report the amounts of such distributions to the Trustee. The duties of the Paying Agent may include the obligation to distribute statements prepared by the Trustee pursuant to Section 4.03 and provide information to Certificateholders as required hereunder. The Paying Agent hereunder shall at all times be an entity duly incorporated and validly existing under the laws of the United States of America or any state thereof, authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authorities. The Paying Agent shall initially be the Trustee. The Trustee may appoint a successor to act as Paying Agent, which appointment shall be reasonably satisfactory to the Depositor.

(b) The Trustee shall cause the Paying Agent (if other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee that such Paying Agent shall hold all sums, if any, held by it for payment to the Certificateholders in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to such Certificateholders and shall agree that it shall comply with all requirements of the Code regarding the withholding of payments in respect of Federal income taxes due from Certificate Owners and otherwise comply with the provisions of this Agreement applicable to it.

THE SERVICER AND THE DEPOSITOR

Section 6.01 Liability of the Servicer and the Depositor.

The Depositor shall be liable in accordance herewith only to the extent of the obligations specifically imposed upon and undertaken by the Depositor.

Section 6.02 Merger or Consolidation of, or Assumption of the Obligations of, the Servicer or the Depositor.

Any entity into which the Servicer or Depositor may be merged or consolidated, or any entity resulting from any merger, conversion or consolidation to which the Servicer or the Depositor shall be a party, or any corporation succeeding to the business of the Servicer or the Depositor, shall be the successor of the Servicer or the Depositor, as the case may be, hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor Servicer shall satisfy all the requirements of Section 7.02 with respect to the qualifications of a successor Servicer.

Section 6.03 Limitation on Liability of the Servicer and Others.

Neither the Servicer nor any of the directors or officers or employees or agents of the Servicer shall be under any liability to the Issuing Entity or the Certificateholders for any action taken or for refraining from the taking of any action by the Servicer in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Servicer or any such Person against any liability which would otherwise be imposed by reason of its willful misfeasance, bad faith or negligence in the performance of duties of the Servicer or by reason of its reckless disregard of its obligations and duties of the Servicer hereunder.

The Servicer and any director or officer or employee or agent of the Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Servicer and any director or officer or employee or agent of the Servicer shall be indemnified by the Issuing Entity and held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Agreement or the Certificates, including any amount paid to the Trustee pursuant to Section 6.06(b), other than any loss, liability or expense related to any specific Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement) and any loss, liability or expense incurred by reason of its willful misfeasance, bad faith or negligence in the performance of its duties hereunder or by reason of its reckless disregard of its obligations and duties hereunder. The Servicer shall not be under any obligation to appear in, prosecute or defend any legal action which is not incidental to its duties to service the Mortgage Loans in accordance with this Agreement, and which in its opinion may involve it in any expense or liability; provided, however, that the Servicer may in its sole discretion undertake any such action which it may deem necessary or desirable in respect of this Agreement, and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the reasonable legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Issuing Entity, and the Servicer shall be entitled to be reimbursed therefor. The Servicer’s right to indemnity or reimbursement pursuant to this Section 6.03 shall survive any resignation or termination of the Servicer pursuant to Section 6.04 or 7.01 with respect to any losses, expenses, costs or liabilities arising prior to such resignation or termination (or arising from events that occurred prior to such resignation or termination). Any reimbursements or indemnification to the Servicer from the Issuing Entity pursuant to this Section 6.03 shall be payable in the priority set forth in Section 4.01 hereof.

Section 6.04 Servicer Not to Resign.

Subject to the provisions of Section 6.02, the Servicer shall not resign from the obligations and duties hereby imposed on it except (i) upon determination that the performance of its obligations or duties hereunder are no longer permissible under applicable law or (ii) upon satisfaction of the following conditions: (a) subject to the rights of a Servicing Rights Pledgee pursuant to Section 3.28, the Servicer has proposed a successor servicer to the Trustee in writing and such proposed successor servicer is reasonably acceptable to the Trustee; and (b) each Rating Agency shall have delivered a letter to the Trustee prior to the appointment of the successor servicer stating that the proposed appointment of such successor servicer as Servicer hereunder will not result in the reduction or withdrawal of then current rating of the Certificates; provided, however, that no such resignation by the Servicer shall become effective until such successor servicer or, in the case of (i) above, the Trustee or its designee as successor Servicer shall have assumed the Servicer’s responsibilities and obligations hereunder or shall have designated a successor servicer in accordance with Section 7.02. Any such resignation shall not relieve the Servicer of responsibility for any of the obligations specified in Sections 7.01 and 7.02 as obligations that survive the resignation or termination of the Servicer. The Servicer shall have no claim (whether by subrogation or otherwise) or other action against any Certificateholder for any amounts paid by the Servicer pursuant to any provision of this Pooling and Agreement. Any such determination permitting the resignation of the Servicer under clause (i) above shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee.

Section 6.05 Delegation of Duties.

In the ordinary course of business, the Servicer at any time may delegate any of its duties hereunder to any Person, including any of its Affiliates, who agrees to conduct such duties in accordance with the same standards with which the Servicer complies pursuant to Section 3.01. Such delegation shall not relieve the Servicer of its liabilities and responsibilities with respect to such duties and shall not constitute a resignation within the meaning of Section 6.04.

Section 6.06 Servicing Rights Owner to Pay Trustee’s Fees and Expenses; Indemnification.

(a) The Servicing Rights Owner covenants and agrees to pay to the Trustee and any co-trustee of the Trustee from time to time, and the Trustee and any such co-trustee shall be entitled to, reasonable compensation, including all indemnification payments (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) for all services rendered by each of them in the execution of the trusts created hereunder and in the exercise and performance of any of the powers and duties and the Servicing Rights Owner will pay or reimburse the Trustee and any co-trustee upon request for all reasonable expenses, disbursements and advances incurred or made by the Trustee or any co-trustee of the Trustee in accordance with any of the provisions of this Agreement except any such expense, disbursement or advance as may arise from its negligence or bad faith.

(b) The Servicing Rights Owner agrees to indemnify the Trustee for, and to defend and hold, the Trustee harmless against, any claim, tax, penalty, loss, liability or expense of any kind whatsoever, incurred without gross negligence or willful misconduct on the part of the Trustee as such and/or in its individual capacity, arising out of, or in connection with, the performance of the Trustee’s duties under this Agreement or the other Basic Documents, including the reasonable costs and expenses (including reasonable legal fees and expenses) of defending itself against any claim in connection with the exercise or performance of any of its powers or duties hereunder, provided that:

(i) with respect to any such claim, the Trustee shall have given the Servicing Rights Owner written notice thereof promptly after the Trustee shall have actual knowledge thereof, provided that failure to promptly notify shall not relieve the Servicing Rights Owner of its liability to indemnify hereunder except to the extent it has been materially prejudiced thereby;

(ii) while maintaining control over its own defense, the Trustee shall cooperate and consult fully with the Servicing Rights Owner in preparing such defense; and

(iii) notwithstanding anything in this Agreement to the contrary, the Servicing Rights Owner shall not be liable for settlement of any claim by the Trustee entered into without the prior consent of the Servicing Rights Owner, which consent shall not be unreasonably withheld.

No termination of this Agreement and resignation and removal of the Trustee shall affect the obligations created by this Section 6.06 of the Servicing Rights Owner to indemnify the Trustee under the conditions and to the extent set forth herein. This section shall survive the termination of this Agreement and resignation and removal of the Trustee. Any amounts to be paid by the Servicing Rights Owner pursuant to this Subsection may not be paid from the Trust Fund except as provided in Section 6.03.

Notwithstanding the foregoing, the indemnification provided by the Servicing Rights Owner in this Section 6.06 shall not pertain to any loss, liability or expense of the Trustee including the costs and expenses of defending itself against any claim, incurred in connection with any actions taken by the Trustee at the direction of the Certificateholders, as the case may be, pursuant to the terms of this Agreement.

(c) The Servicer agrees to indemnify the Trust Fund in an amount equal to the amount of any claim made under a MI Policy for which coverage is denied by the MI Insurer because (and if the MI Insurer’s denial of coverage is contested by the Servicing Rights Owner or the Servicer, a court or arbitrator finally determines that coverage is not available under the MI Policy because) of the Servicer’s failure to abide by the terms of the MI Policy or the MI Insurance Agreement or the Servicer’s failure to abide by the NFI Underwriting Guidelines or the NFI Servicing Guidelines, as attached to the MI Insurance Agreement.

(d) In the event the Trustee becomes the Servicer pursuant to Section 7.02 hereof, the Trustee shall not be obligated, in its individual capacity, to pay any obligation of the Servicer under clause (c) above or clause (e) below.

(e) To the extent any amounts set forth in clause (a) or (b) above are not paid by the Servicing Rights Owner for any reason, such amounts shall be paid by the Servicer, except that, if the successor servicer is the Trustee, then any such amounts shall be paid by NovaStar Mortgage, Inc.

(vii) The Rolling 90 Day Delinquency Percentage exceeds 21.00%.

(b) then, and in each and every such case, so long as a Servicing Default shall not have been remedied within the applicable grace period, (x) with respect solely to clause (a)(i)(A) above, if such Advance is not made by 5:00 P.M., New York time, on the Business Day immediately following the Servicer Remittance Date (provided the Trustee shall give the Servicer notice of such failure to advance by 5:00 P.M., New York time, on the Servicer Remittance Date), the Trustee shall terminate all of the rights and obligations of the Servicer under this Agreement and the Trustee, or a successor servicer appointed in accordance with Section 7.02, shall assume, pursuant to Section 7.02, the duties of a successor Servicer and (y) in the case of (a)(i)(B), (a) (ii), (a) (iii), (a) (iv), (a) (v), (a) (vi) and (a) (vii) above, the Trustee shall, at the direction of the Holders of Certificates evidencing at least 51% of the Voters Rights, by notice then given in writing to the Servicer (and to the Trustee if given by Holders of Certificates), terminate all of the rights and obligations of the Servicer as servicer under this Agreement. Any such notice to the Servicer shall also be given to the Servicing Rights Pledgee, Trustee, each Rating Agency, the Depositor, each Hedge Counterparty (if prior to the Class I Termination Date) and the Sponsor. On or after the receipt by the Servicer (and by the Trustee if such notice is given by the Holders) of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee or other successor Servicer appointed in accordance with Section 7.02.

In the event of a Servicing Default, notwithstanding anything to the contrary in this agreement, the Trustee and the Depositor hereby agree that upon delivery to the Trustee by the Servicing Rights Pledgee of a letter signed by the Servicing Rights Pledgee within 15 days of when the Servicer provides the Servicing Rights Pledgee notice of such Servicing Default, the Servicing Rights Pledgee or its designee shall be appointed as successor Servicer, provided that at the time of such appointment, the Servicing Rights Pledgee or such designee meets the requirements of a successor Servicer set forth in Section 7.02 below, the Servicing Rights Pledgee or such designee agrees to be subject to the terms of this Agreement and the Servicing Rights Pledgee or such designee assumes the Advance obligations of the Trustee as outlined in Section 7.02(a), provided, however, that at such time the Servicing Rights Pledgee will have the right to reimbursement as outlined in Section 3.07.

Section 7.02 Trustee to Act; Appointment of Successor.

(a) Within 90 days of the time the Servicer (and the Trustee if notice is sent by the Holders) receives a notice of termination pursuant to Section 7.01, the Trustee (or such other successor Servicer as is approved in accordance with this Agreement) shall be the successor in all respects to the Servicer in its capacity as servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Servicer by the terms and provisions hereof arising on and after its succession. Notwithstanding the foregoing, the parties hereto agree that the Trustee, in its capacity as successor Servicer, immediately will assume all of the obligations of the Servicer to make Advances; provided however, that the obligation of the Trustee to make Advances is subject to the standards set forth in Section 3.25 hereof. Notwithstanding the foregoing, the Trustee, in its capacity as successor Servicer, shall not be responsible for the lack of information and/or documents that it cannot obtain through reasonable efforts. As compensation therefor, the Trustee (or such other successor Servicer) shall be entitled to such compensation as the Servicer would have been entitled to hereunder if no such notice of termination had been given. Notwithstanding the above, (i) if the Trustee is unwilling to act as successor Servicer or (ii) if the Trustee is legally unable so to act, the Trustee shall appoint or petition a court of competent jurisdiction to appoint, any established housing and home finance institution, bank or other mortgage loan or home equity loan servicer having a net worth of not less than $100,000,000 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; provided, that the appointment of any such successor Servicer will not result in the qualification, reduction or withdrawal of the ratings assigned to the Certificates by the Rating Agencies as evidenced by a letter to such effect from the Rating Agencies. Pending appointment of a successor to the Servicer hereunder, unless the Trustee is prohibited by law from so acting, the Trustee shall act in such capacity as hereinabove provided. In connection with such appointment and assumption, the successor (including the Trustee as successor Servicer) shall be entitled to receive compensation out of payments on Mortgage Loans in an amount equal to the compensation which the Servicer would otherwise have received pursuant to Section 3.15 (or such other compensation as the Trustee and such successor shall agree, not to exceed the Servicing Fee). The appointment of a successor Servicer shall not affect any liability of the predecessor Servicer which may have arisen under this Agreement prior to its termination as Servicer to pay any deductible under an insurance policy pursuant to Section 3.11 or to indemnify the Trustee pursuant to Section 3.06, nor shall any successor Servicer be liable for any acts or omissions of

the predecessor Servicer or for any breach by such Servicer of any of its representations or warranties contained herein or in any related document or agreement. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. All Servicing Transfer Costs shall be paid by the predecessor Servicer upon presentation of reasonable documentation of such costs, and if such predecessor Servicer defaults in its obligation to pay such costs, such costs shall be paid by the successor Servicer (in which case the successor Servicer shall be entitled to reimbursement therefor from the assets of the Issuing Entity) or if not paid, then by the Trustee from the Trust Fund.

(b) Any successor, including the Trustee, to the Servicer as servicer shall during the term of its service as servicer continue to service and administer the Mortgage Loans for the benefit of Certificateholders, and maintain in force a policy or policies of insurance covering errors and omissions in the performance of its obligations as Servicer hereunder and a Fidelity Bond in respect of its officers, employees and agents to the same extent as the Servicer is so required pursuant to Section 3.11.

(c) In connection with the termination or resignation of the Servicer hereunder, either (i) the successor Servicer, shall represent and warrant that it is a member of MERS in good standing and shall agree to comply in all material respects with the rules and procedures of MERS in connection with the servicing of the Mortgage Loans that are registered with MERS, in which case the predecessor Servicer shall cooperate with the successor Servicer in causing MERS to revise its records to reflect the transfer of servicing to the successor Servicer as necessary under MERS’ rules and regulations, or (ii) the predecessor Servicer shall cooperate with the successor Servicer in causing MERS to execute and deliver an assignment of Mortgage in recordable form to transfer the Mortgages from MERS to the Trustee and to execute and deliver such other notices, documents and other instruments as may be necessary or desirable to effect a transfer of such Mortgage Loans or servicing of such Mortgage Loan on the MERS System to the successor Servicer. The predecessor Servicer shall file or cause to be filed any such assignment in the appropriate recording offices. The predecessor Servicer shall bear any and all fees of MERS, costs of preparing any assignments of Mortgage, and fees and costs of filing any assignments of Mortgage that may be required under this subsection (c). The successor Servicer shall cause assignment to be delivered to the Trustee promptly upon receipt of the original with evidence of recording thereon or a copy certified by the public recording office in which such assignment was recorded.

Section 7.03 Waiver of Defaults.

The Majority Certificateholders may, on behalf of all Certificateholders, waive any events permitting removal of the Servicer as servicer pursuant to this Article VII by delivering written notice to the Trustee, provided, however, that the Majority Certificateholders may not waive a default in making a required distribution on a Certificate without the consent of the Holder of such Certificate. Upon any waiver of a past default, such default shall cease to exist and any Servicing 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 thereto except to the extent expressly so waived. Notice of any such waiver shall be given by the Trustee to the Rating Agencies.

Section 7.04 Notification to Certificateholders.

(a) Upon any termination or appointment of a successor to the Servicer pursuant to this Article VII, the Trustee shall give prompt written notice thereof to the Hedge Counterparties, if prior to the Class I Termination Date, to the Certificateholders at their respective addresses appearing in the Certificate Register and to each Rating Agency.

(b) No later than 60 days after the occurrence of any event which constitutes or which, with notice or a lapse of time or both, would constitute a Servicing Default for five Business Days after a Responsible Officer of the Trustee obtains actual knowledge or written notice of the occurrence of such an event, the Trustee shall transmit by mail to the Hedge Counterparties, if prior to the Class I Termination Date, and all Certificateholders notice of such occurrence unless such default or Servicing Default shall have been waived or cured.

Section 7.05 Survivability of Servicer Liabilities.

Notwithstanding anything herein to the contrary, upon termination of the Servicer hereunder, any liabilities of the Servicer which accrued prior to such termination shall survive such termination.

ARTICLE VIII

THE TRUSTEE

Section 8.01 Duties of the Trustee.

On the Closing Date, the Trustee will act as paying agent and will distribute the proceeds from the sale of the Offered Certificates according to the closing settlement statement provided by the Sponsor. If a Servicing Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Agreement and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(a) Except during the continuance of a Servicing Default:

(i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Agreement with respect to the Trustee and no implied covenants or obligations shall be read into this Agreement against the Trustee; and

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement; provided, however, that the Trustee shall examine the certificates and opinions delivered to it to determine whether or not they conform on their face to the requirements of this Agreement.

(b) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(i) this paragraph does not limit the effect of paragraph (9) of this Section 8.01;

(ii) the Trustee shall not be liable for any error of judgment made in good faith by its Responsible Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

(iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it from the Majority Certificateholders.

The Trustee shall not be liable for interest on any money received by the Trustee.

Money held in trust by the Trustee need not be segregated from other trust funds except to the extent required by law or the terms of this Agreement.

No provision of this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Subject to the other provisions of this Agreement and without limiting the generality of this Section 8.01, the Trustee shall have no duty (A) to see to any recording, filing or depositing of this Agreement or any agreement referred to herein or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of any such recording or filing or depositing or to any rerecording, refiling or redepositing of any thereof, (B) to see to any insurance, (C) to see to the payment or discharge of any tax, assessment, or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Trust Fund other than from funds available in the Distribution Account, or (D) to confirm or verify the contents of any reports or certificates of the Servicer delivered to the Trustee believed by the Trustee to be genuine and to have been signed or presented by the proper party or parties.

(d) For all purposes under this Agreement, the Trustee shall not be deemed to have notice or knowledge of any Servicing Default unless a Responsible Officer assigned to and working in the Trustee’s corporate trust department has actual knowledge thereof or unless written notice of any event which is in fact such Servicing Default is received by the Trustee at the Corporate Trust Office, and such notice references the Certificates generally, the Issuing Entity, or this Agreement.

The Trustee is hereby authorized to execute and shall execute this Agreement and the Purchase Agreement and shall perform their respective duties and satisfy their respective obligations thereunder. Every provision of this Agreement relating to the conduct or affecting the liability of or affording protection to the Trustee shall apply to the Trustee’s execution of this Agreement and the Purchase Agreement and the performance of their respective duties and satisfaction of its obligations hereunder and thereunder.

In order to comply with laws, rules and regulations applicable to banking institutions, including those relating to the funding of terrorist activities and money laundering, the Trustee is required to obtain, verify and record certain information relating to individuals and entities which maintain a business relationship with the Trustee. Accordingly, each of the parties agrees to provide to the Trustee upon its request from time to time such party’s complete name, address, tax identification number and such other identifying information together with copies of such party’s constituting documentation, securities disclosure documentation and such other identifying documentation as may be available for such party.

Section 8.02 Rights of Trustee.

The Trustee may rely and shall be protected in acting or refraining from acting on any resolution, officer’s certificate, opinion of counsel, certificate of auditors or other certificate, statement, instrument, or document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel reasonably satisfactory in form and substance to the Trustee which Officers’ Certificate or Opinion of Counsel shall not be at the expense of the Trustee or the Trust Fund. The Trustee shall not be liable for any action either of them takes or omits to take in good faith in reliance on an Officers’ Certificate or Opinion of Counsel.

The Trustee may execute any of its trusts or powers hereunder and the Trustee may perform any of its respective duties hereunder either directly or by or through agents or attorneys or a custodian or nominee and the Trustee shall have no liability for any misconduct or negligence on the part of such agent, attorney or custodian appointed by the Trustee with due care; provided, further, that the Trustee shall not be responsible for any act or omission of the Custodian.

The Trustee shall not be liable for any action either of them takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful misconduct, negligence or bad faith.

The Trustee may consult with counsel chosen by it with due care, and the advice or opinion of counsel with respect to legal matters relating to this Agreement and the Certificates shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by either of them hereunder in good faith and in accordance with the advice or opinion of such counsel.

The Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders, pursuant to the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby (which in the case of the Majority Certificateholders will be deemed to be satisfied by a letter agreement with respect to such costs from such Majority Certificateholders); nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of a Servicing Default of which a Responsible Officer of the Trustee shall have actual knowledge (which has not been cured), 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 such person’s own affairs.

The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing to do by the Majority Certificateholders; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Agreement, the Trustee may require indemnity reasonably satisfactory to it against such cost, expense or liability as a condition to taking any such action. The reasonable expense of every such examination shall be paid by the Servicer or, if paid by the Trustee, shall be repaid by the Servicer upon demand from the Servicer’s own funds.

The rights of the Trustee to perform any discretionary act enumerated in this Agreement shall not be construed as a duty, and the Trustee shall not be answerable for other than its negligence or willful misconduct in the performance of such act.

The Trustee shall not be required to give any bond or surety in respect of the execution of the Trust Fund created hereby or the powers granted hereunder.

Section 8.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Certificates and may otherwise deal with the Sponsor or its Affiliates with the same rights it would have if it were not Trustee. Any Certificates Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Section 8.11 hereof.

Section 8.04 Trustee’s Disclaimer.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Agreement or the Certificates, or of any Mortgage Loan or related document, or of MERS or the MERS System. The Trustee shall not be accountable for the use of the proceeds from the Certificates, and the Trustee shall not be responsible for any statement

of the Issuing Entity in this Agreement or in any document issued in connection with the sale of the Certificates or in the Certificates other than the Trustee’s or the Certificate Registrar’s certificate of authentication.

Section 8.05 Notice of Servicing Default.

The Trustee shall mail to each Certificateholder notice of the Servicing Default within 10 days after a Responsible Officer has actual knowledge thereof unless such Servicing Default shall have been waived or cured. Except in the case of a Servicing Default in payment of principal of or interest on any Certificate, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in the interests of Certificateholders.

Section 8.06 [Reserved].

Section 8.07 Compensation.

The amount of the Trustee Fee and Custodian Fee shall be paid to the Trustee and Custodian, respectively, on each Distribution Date pursuant to Section 4.01(a)(i) of this Agreement, and all amounts owing to the Trustee hereunder in excess of such amount shall be paid solely as provided in this Agreement. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.

Section 8.08 Replacement of Trustee.

No resignation or removal of the Trustee and no appointment of a successor Trustee shall become effective until the acceptance of appointment by the successor Trustee pursuant to this Section 8.08. The Trustee may resign at any time by so notifying the Hedge Counterparties, if prior to the Class I Termination Date, and the Depositor. The Majority Certificateholders may at any time remove the Trustee by so notifying the Hedge Counterparties, if prior to the Class I Termination Date, the Depositor and the Trustee, and the Depositor may appoint a successor Trustee. The Depositor shall remove the Trustee if:

(a) the Trustee fails to comply with Section 8.11 hereof;

(b) the Trustee is adjudged a bankrupt or insolvent;

(d) the Trustee otherwise becomes incapable of acting as a trustee with trust powers.

If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Depositor shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee, the Depositor, the Rating Agencies and the Servicer. Thereupon, the resignation

or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee or under this Agreement. The successor Trustee shall mail a notice of its succession to Hedge Counterparties, if prior to the Class I Termination Date, and the Certificateholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Depositor, the Trustee or the Majority Certificateholders may petition any court of competent jurisdiction for the appointment of a successor Trustee.

Section 8.09 Successor Trustee by Merger.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation, without any further act, shall be the successor Trustee; provided, that such corporation or banking association shall be otherwise qualified and eligible under Section 8.11 hereof.

If at the time such successor or successors by merger, conversion or consolidation to the Trustee, shall succeed to the trusts created by this Agreement and any of the Certificates shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Certificates so authenticated; and if at that time any of the Certificates shall not have been authenticated, any successor to the Trustee may authenticate such Certificates either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force as the Certificates or this Agreement provide that such certificates of the Trustee shall have.

Section 8.10 Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which any part of the Trust Fund may at the time be located, the Trustee shall, at the expense of the Trust Fund, have the power and may execute and deliver all instruments to appoint one or more Persons to act as a co-trustee or co-trustees, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust Fund, or any part hereof, and, subject to the other provisions of this Section, 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 8.11 hereof and notice to, and no consent of the Certificateholders of the appointment of any co-trustee or separate trustee shall be required.

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

(a) 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 (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

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

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

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.

(f) The Trustee, the Servicer and the Holders of Certificates shall take any action or cause the REMIC to take any action necessary to create or maintain the status of each REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. Neither the Trustee, the Servicer nor the Holder of any Residual Certificate shall take any action, cause any REMIC created hereunder to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of such REMIC as a REMIC or (ii) result in the imposition of a tax upon such REMIC (including but not limited to the tax on prohibited transactions as defined in Code Section 860F(a)(2) and the tax on prohibited contributions set forth on Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee and the Servicer have received an Opinion of Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not endanger such status or result in the imposition of such a tax. In addition, prior to taking any action with respect to any REMIC created hereunder or the assets therein, or causing such REMIC to take any action, which is not expressly permitted under the terms of this Agreement, any Holder of a

Residual Certificate will consult with the Trustee and the Servicer, or their respective designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall take any such action or cause any REMIC to take any such action as to which the Trustee or the Servicer has advised it in writing that an Adverse REMIC Event could occur.

(g) Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on each REMIC created hereunder by federal or state governmental authorities. To the extent that such Issuing Entity taxes are not paid by a Residual Certificateholder, the Trustee shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Residual Certificate in the REMICs or, if no such amounts are available, out of other amounts held in the Distribution Account, and shall reduce amounts otherwise payable to Holders of regular interests in the related REMIC.

(h) The Trustee, as agent for the Tax Matters Person, shall, for federal income tax purposes, maintain books and records with respect to each REMIC created hereunder on a calendar year and on an accrual basis.

(i) After the Closing Date, no additional contributions of assets shall be made to any REMIC created hereunder, except as expressly provided in this Agreement with respect to Qualified Replacement Mortgages.

(j) Neither of the Trustee nor the Servicer shall enter into any arrangement by which any REMIC created hereunder will receive a fee or other compensation for services.

(k) The Trustee will apply for an Employee Identification Number from the Internal Revenue Service via a Form SS-4 or other acceptable method for REMIC I, REMIC II, REMIC III, REMIC IV and the Master REMIC.

(l) The Trustee shall treat the Supplemental Interest Trust as an outside reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h) that is owned by the Holders of the Class CA Certificates and that is not an asset of any REMIC. The Trustee shall treat the rights of the holders of the Class A and Mezzanine Certificates to receive any interest payments in excess of the REMIC Pass-Through Rate on the Master REMIC Regular Interest corresponding to such Class of Certificates as rights in an interest rate cap contract written by the Class CA Certificateholders in favor of the holders of the Class A and Mezzanine Certificates. Thus, each Class A and Mezzanine Certificate shall be treated as representing not only ownership of a regular interest in the Master REMIC, but also ownership of an interest in an interest rate cap contract. Furthermore, the Trustee shall treat the obligation of the Holders of the Class A and Mezzanine Certificates to make certain payments to the Supplemental Interest Account to the extent that the payment on the Pass-Through Rate on the Master REMIC Regular Interest exceeds the interest payment on the corresponding Class of Certificates as an obligation to make payments pursuant to an interest rate cap contract written by the Holders of the Class A and Mezzanine Certificates in favor of the Class CA Certificateholder. In no event shall any payments provided for in this subsection be treated as payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1). The pledge of payments on the Class CB Certificates to the Supplemental Interest Trust will be treated as a limited

guaranty written by the Holder of the Class CB Certificate for the benefit of the Holders of the Class CA Certificate. Such guaranty is expected to have nominal value. To the extent that the Class CB Interest Distributable Amount paid to the Supplemental Interest Trust as described in Section 10.01(n) is not paid in full to the Holders of the Class CB Certificates pursuant to Section 4.04(c)(v), a right of reimbursement will arise in favor of the Holders of the Class CB Certificates against the Holders of the Class CA Certificates.

(m) Notwithstanding the priority and sources of payments set forth in Article IV hereof or otherwise, the Trustee shall account for all distributions on the Certificates as set forth in this section.

(n) For federal income tax purposes, payments pursuant to Section 4.01(a)(i)(O) shall be treated as having been made to the extent of remaining Interest Remittance Amount (i) first, to the Holders of the Class CA Certificates, the Class CA Interest Distributable Amount and (ii) second, to the Holders of the Class CB Certificates, the Class CB Interest Distributable Amount.

(o) For federal income tax purposes, payments of Excess Cashflow pursuant to Section 4.04(d)(i) will be treated as having been made (i) first, from Excess Cashflow relating to the Class CB Interest Distributable Amount and (ii) second, from Excess Cashflow relating to amounts otherwise distributable on the Class CA Certificates.

(p) None of the Class M-7 DSI Certificates, Class M-10 DSI Certificates, Class M-11 DSI Certificates or the Class M-12 DSI Certificates will be treated as regular or residual interest in any REMIC created hereunder.

Section 10.02 Prohibited Transactions and Activities.

Except as specifically provided in this Agreement, none of the Depositor, the Servicer nor the Trustee shall sell, dispose of, or substitute for any of the Mortgage Loans, if such disposition, acquisition, substitution, or acceptance would (a) affect adversely the status of any REMIC created hereunder as a REMIC or (b) cause any REMIC created hereunder to be subject to a tax on prohibited transactions or prohibited contributions pursuant to the REMIC Provisions.

ARTICLE XI

TERMINATION

Section 11.01 Termination.

(a) The respective obligations and responsibilities of the Sponsor, the Servicer, the Depositor and the Trustee created hereby (other than the obligation of the Trustee to make certain payments to Certificateholders after the final Distribution Date and the obligation of the Servicer to send certain notices as hereinafter set forth and the obligation of the Servicer to indemnify the Trustee in accordance with Section 6.06) shall terminate upon notice to the Trustee upon the earliest of (i) the Distribution Date on which the Certificate Principal Balances of the Regular Certificates have been reduced to zero, (ii) the final payment or other liquidation

of the last Mortgage Loan held by the Issuing Entity, (iii) the optional purchase by the Servicer of the Mortgage Loans as described below and (iv) the Assumed Final Maturity Date. Notwithstanding the foregoing, in no event shall the trust created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Xxxxxx X. Xxxxxxx, the late ambassador of the United States to the Court of St. Xxxxx, living on the date hereof.

The Servicer may, at its option, terminate this Agreement on any date on which the aggregate of the Principal Balances of the Mortgage Loans on such date is equal to or less than 10% of the Maximum Collateral Amount, by purchasing, on the next succeeding Distribution Date, all of the outstanding Mortgage Loans and REO Properties at a price equal to the aggregate Principal Balance of the Mortgage Loans and REO Properties plus accrued and unpaid interest thereon at the weighted average of the Mortgage Rates through the end of the Due Period preceding the final Distribution Date plus unreimbursed Servicing Advances, Advances, any unpaid Servicing Fees allocable to such Mortgage Loans and REO Properties, any accrued and unpaid Available Funds Cap Shortfall Amount and Available Funds Cap Carryforward Amount (without duplication of amounts already paid) and any unpaid amount due the Trustee, the Hedge Counterparties and the Custodian under this Agreement; provided, however, that in no event shall such price be less than the amount necessary to pay the sum of (i) 100% of the aggregate Certificate Principal Balance of each Class of Certificates, (ii) accrued and unpaid interest thereon at the related Pass-Through Rate (including accrued and unpaid interest at the related REMIC Pass-Through Rate for the Class CA and Class CB Certificates) through the date on which the trust is terminated, (iii) any unpaid Administrative Fees and (iv) any unpaid amount due to the Hedge Counterparties (including any Hedge Termination Payments) (the “Termination Price”); provided, however, that such option may only be exercised if the Termination Price is sufficient to pay all interest accrued on, as well as amounts necessary to retire the principal balance of, each class of net interest margin notes issued pursuant to the Indenture at the time the option is exercised.

In connection with any such purchase pursuant to and subject to the requirements of the preceding paragraph, the Servicer shall deposit in the Distribution Account all amounts then on deposit in the Collection Account, which deposit shall be deemed to have occurred immediately preceding such purchase, and which amount shall be applied in accordance with the priorities set forth in Article IV hereof.

Any such purchase shall be accomplished by deposit into the Distribution Account on the Distribution Date of the Termination Price.

The Servicer may assign or pledge to any Person its right to exercise the foregoing option by giving written notice of the assignment or pledge to the Trustee. Any assignee of such option may further assign or pledge its interest in such option.

(b) In the event that the Certificate Principal Balances of all of the Class A and Mezzanine have not been reduced to zero by the Assumed Final Maturity Date, the Trustee, shall (i) sign a plan of complete liquidation prepared and provided to it by the Servicer of each REMIC created hereunder meeting the requirements of a “Qualified Liquidation” under Section 860F of the Code and any regulations thereunder, (ii) sell all of the assets of the Trust Fund for

cash, pursuant to the terms of the plan of complete liquidation, (iii) distribute the proceeds of the sale to the Certificateholders in accordance with Section 4.01 hereof, and (iv) terminate the Issuing Entity. By their acceptance of Certificates, the Holders thereof hereby agree to appoint the Trustee as their attorney in fact to: (i) adopt such a plan of complete liquidation (and the Certificateholders hereby appoint the Trustee as their attorney in fact to sign such a plan) as appropriate and (ii) to take such other action in connection therewith as may be reasonably required to carry out such plan of complete liquidation in accordance with the terms thereof.

(c) Notice of any termination, specifying the Distribution Date (which shall be a date that would otherwise be a Distribution Date) upon which the Certificateholders may surrender their Certificates to the Trustee for payment of the final distribution and cancellation, shall be given promptly by the Trustee upon the Trustee receiving notice of such date from the Servicer, by letter to the Hedge Counterparties (if prior to the Class I Termination Date) and the Certificateholders mailed not earlier than the 15th day and not later than the 25th day of the month next preceding the month of such final distribution specifying (1) the Distribution Date upon which final distribution of the Certificates will be made upon presentation and surrender of such Certificates at the office or agency of the Trustee therein designated, (2) the amount of any such final distribution and (3) 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 or agency of the Trustee therein specified.

(d) Upon presentation and surrender of the Certificates, the Trustee shall cause to be distributed to the Holders of the Certificates on the Distribution Date for such final distribution, in proportion to the Percentage Interests of their respective Class and to the extent that funds are available for such purpose, an amount equal to the amount required to be distributed to such Holders in accordance with the provisions of Section 4.01 for such Distribution Date.

(e) In the event that all Certificateholders shall not surrender their Certificates for final payment and cancellation on or before such final Distribution Date, the Trustee shall promptly following such date cause all funds in the Distribution Account not distributed in final distribution to Certificateholders to be withdrawn therefrom and credited to the remaining Certificateholders by depositing such funds in a separate trust account for the benefit of such Certificateholders, which shall be held uninvested, and the Servicer (if the Servicer has exercised its right to purchase the Mortgage Loans) or the Trustee (in any other case) shall give a second written notice to the remaining Certificateholders, to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within nine months after the second notice all the Certificates shall not have been surrendered for cancellation, the Residual Certificateholder shall be entitled to all unclaimed funds and other assets which remain subject hereto, and the Trustee upon transfer of such funds shall be discharged of any responsibility for such funds, and the Certificateholders shall look to the Residual Certificateholder for payment.

Section 11.02 Additional Termination Requirements.

(a) In the event that the Servicer exercises its purchase option as provided in Section 11.01 or the Trustee terminates the Issuing Entity, each REMIC shall be terminated in accordance with the following additional requirements, unless the Trustee shall have been

furnished with an Opinion of Counsel to the effect that the failure of the Issuing Entity to comply with the requirements of this Section will not (i) result in the imposition of taxes on “prohibited transactions” of the Issuing Entity as defined in Section 860F of the Code or (ii) cause any REMIC constituting part of the Issuing Entity to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(i) Within 90 days prior to the final Distribution Date, the Servicer shall adopt and prepare, and the Trustee shall sign, a plan of complete liquidation of each REMIC created hereunder meeting the requirements of a “Qualified Liquidation” under Section 860F of the Code and any regulations thereunder; and

(ii) At or after the time of adoption of such a plan of complete liquidation and at or prior to the final Distribution Date, the Trustee shall sell all of the assets of the Trust Fund to the Servicer for cash pursuant to the terms of the plan of complete liquidation.

(b) By their acceptance of Certificates, the Holders thereof hereby agree to appoint the Trustee as their attorney in fact to: (i) adopt such a plan of complete liquidation (and the Certificateholders hereby appoint the Trustee as their attorney in fact to sign such plan) as appropriate and (ii) to take such other action in connection therewith as may be reasonably required to carry out such plan of complete liquidation all in accordance with the terms hereof.

ARTICLE XII

MISCELLANEOUS PROVISIONS

Section 12.01 Amendment.

This Agreement may be amended from time to time by the parties hereto, and without the consent of the Certificateholders or the Hedge Counterparties (i) to cure any ambiguity, (ii) to correct or supplement any provisions herein which may be defective or inconsistent with any other provisions herein or (iii) to make any other provisions with respect to matters or questions arising under this Agreement which shall not be inconsistent with the provisions of this Agreement; provided that any such amendment will have no material adverse effect, as evidenced by an Opinion of Counsel as described below, on the Hedge Counterparties provided, however, that any such action listed in clause (i) through (iii) above shall be deemed not to adversely affect in any respect the interests of (A) any Certificateholder, if evidenced by (i) written notice to the Depositor, the Servicer and the Trustee from the Rating Agencies that such action will not result in the reduction or withdrawal of the rating of any outstanding Class of Certificates with respect to which it is a Rating Agency or (ii) an Opinion of Counsel delivered to the Servicer, the Depositor and the Trustee and (B) any Hedge Counterparty, (i) if evidenced by an opinion of counsel from outside counsel of recognized international reputation in the field of sophisticated financial transactions delivered to the Servicer, the Depositor, the Trustee, each Hedge Counterparty with a copy to the Rating Agencies stating that such actions will have no material adverse effect on the Hedge Counterparties or (ii) if the written consent of the Hedge Counterparties is obtained. This Agreement may be amended by the parties hereto without the consent of the Hedge Counterparties after the Class I Termination Date.

In addition, this Agreement may be amended from time to time by the parties hereto with the consent of the Majority Certificateholders for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided, however, that no such amendment or waiver shall (w) reduce in any manner the amount of, or delay the timing of, payments on the Certificates or distributions which are required to be made on any Certificate without the consent of the Holder of such Certificate, (x) adversely affect in any material respect the interests of the Holders of any Class of Certificates in a manner other than as described in clause (w) above, without the consent of the Holders of Certificates of such Class evidencing at least a 66% Percentage Interest in such Class, (y) reduce the percentage of Voting Rights required by clause (x) above without the consent of the Holders of all Certificates of such Class then outstanding or (z) have a material adverse effect on the interests of the Hedge Counterparties without such Hedge Counterparties’ written consent. Upon approval of an amendment, a copy of such amendment shall be sent to the Rating Agencies.

Notwithstanding the provisions of this Section 12.01, Sections 3.17 and 3.18 may be amended as necessary to comply with the provisions of Regulation AB without the consent of the Certificateholders.

The Servicer shall send to the Hedge Counterparties (for so long as the Hedge Agreements are outstanding) a copy of any executed amendment made pursuant to this Section 12.01. If the consent of the Hedge Counterparties is required for any amendment, a copy of such proposed amendment shall be sent to the Hedge Counterparties 10 days (or such shorter time period as shall be agreed to by the parties) prior to the effective date thereof.

Notwithstanding any provision of this Agreement to the contrary, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel, delivered by (and at the expense of) the Person seeking such Amendment, to the effect that such amendment will not result in the imposition of taxes on “prohibited transactions” of the Issuing Entity as defined in Section 860F of the Code or cause any REMIC constituting part of the Issuing Entity to fail to qualify as a REMIC at any time that any Certificates are outstanding, and that the amendment is being made in accordance with the terms hereof. Additionally, prior to entering into any amendment, the Trustee shall be entitled to receive from the party requesting such amendment an Opinion of Counsel stating that such amendment is authorized and permitted pursuant to the terms of this Agreement and all conditions precedent to its execution and delivery have been satisfied.

Promptly after the execution of any such amendment the Trustee shall furnish, at the expense of the Person that requested the amendment if such Person is the Sponsor or the Servicer (but in no event at the expense of the Trustee), otherwise at the expense of the Issuing Entity, a copy of such amendment and the Opinion of Counsel referred to in the immediately preceding paragraph to the Servicer and each Rating Agency.

It shall not be necessary for the consent of Certificateholders under this Section 12.01 to approve the particular form of any proposed amendment; instead 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.

The Trustee shall not be obligated to enter into any amendment pursuant to this Section 12.01 that affects its rights, duties and immunities under this Agreement or otherwise.

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 together constitute but one and the same instrument.

Section 12.03 Limitation on Rights of Certificateholders.

The death or incapacity of any Certificateholder shall not (i) operate to terminate this Agreement or the Issuing Entity, (ii) entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of the Issuing Entity, or (iii) otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

Except as expressly provided for herein, no Certificateholder shall have any right to vote or in any manner otherwise control the operation and management of the Issuing Entity, 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 person 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 of any provision 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 default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of Certificates entitled to at least 25% of the Voting Rights shall have made written request upon 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 as it may reasonably require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 15 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 is understood and intended, and 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 of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, which priority or preference is not otherwise provided for herein, or to enforce any right under this Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 12.03 each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 12.04 Compliance with Regulation AB.

Each of the parties hereto acknowledges and agrees that the purpose of Sections 3.17 and 3.18 of this Agreement is to facilitate compliance by the Sponsor and the Depositor with the provisions of Regulation AB, as such may be amended or clarified from time to time. Therefore, each of the parties agrees that (a) the obligations of the parties hereunder shall be interpreted in such a manner as to accomplish compliance with Regulation AB, (b) the parties’ obligations hereunder will be supplemented and modified as necessary to be consistent with any such amendments, interpretive advice or guidance, convention or consensus among active participants in the asset-backed securities markets, advice of counsel, or otherwise in respect of the requirements of Regulation AB and (c) the parties shall comply, to the extent practicable from a timing and information systems perspective, with requests made by the Sponsor or the Depositor for delivery of additional or different information as the Sponsor or the Depositor may determine in good faith is necessary to comply with the provisions of Regulation AB.

Section 12.08 Article and Section References.

All article and section references used in this Agreement, unless otherwise provided, are to articles and sections in this Agreement.

Section 12.09 Further Assurances.

Notwithstanding any other provision of this Agreement, the Trustee shall not have any obligation to consent to any amendment or modification of this Agreement unless they have been provided reasonable security or indemnity against their out-of-pocket expenses (including reasonable attorneys’ fees) to be incurred in connection therewith.

Section 12.10 Benefits of Agreement.

Nothing in this Agreement or in the Certificates, expressed or implied, shall give to any Person, other than the Certificateholders, the Hedge Counterparties and the parties hereto and their successors hereunder, any benefit or any legal or equitable right, remedy or claim under this Agreement. For the avoidance of doubt, the parties agree that each of the Hedge Counterparties, prior to the Class I Termination Date, and the Servicing Rights Pledgee are intended and shall have all rights of a third-party beneficiary of this Agreement.

Section 12.11 Acts of Certificateholders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by the Certificateholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Certificateholders in person or by agent duly appointed in writing, and such action shall become effective when such instrument or instruments are delivered to the Trustee, the Sponsor and the Servicer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “act” of the Certificateholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement and conclusive in favor of the Trustee and the Issuing Entity, if made in the manner provided in this Section 12.11.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Whenever such execution is by a signer acting in a capacity other than his or her individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.

(c) Any request, demand, authorization, direction, notice, consent, waiver or other action by any Certificateholder shall bind every future Holder of such Certificate and the Holder of every Certificate issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, in respect of anything done, omitted or suffered to be done by the Trustee or the Issuing Entity in reliance thereon, whether or not notation of such action is made upon such Certificate.

Section 12.12 Confidentiality.

The Trustee hereby agrees to hold and treat all Confidential Information (as defined below) provided to it in connection with the offering of the Certificates in confidence and in accordance with this Section 12.12, and will implement and maintain safeguards in accordance with the “Interagency Guidelines Establishing Standards for Safeguarding Customer Information” as required by Appendix B to 12 CFR, Chapter I, Part 30, to further assure the confidentiality of such Confidential Information. Such Confidential Information will not, without the prior written consent of the Servicer, be disclosed or used by the Trustee or by its subsidiaries or, affiliates, or its or their directors, officers, employees, agents or controlling persons or agents or advisors (collectively, the “Information Recipients”) other than for the purposes of (i) structuring the securitization transaction and the facilitating the issuance of the Certificates, or (ii) in connection with the performance of its required due diligence on the Mortgage Loans.

NOVASTAR MORTGAGE, INC., as Servicer

Unless this certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation (“DTC”), to the Issuing Entity or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.

(This certificate does not represent an interest in, or an obligation of, nor are the underlying Mortgage Loans insured or guaranteed by, NovaStar Mortgage, Inc., NovaStar Mortgage Funding Corporation, NovaStar Financial, Inc., NovaStar Capital, Inc., the Trustee or any of their subsidiaries and affiliates. This certificate is comprised of a Certificate representing a fractional ownership interest in distributions in certain Accounts created pursuant to the Pooling and Servicing Agreement and certain other rights relating thereto and is payable only from amounts received by the Trustee relating to the Mortgage Loans and other assets held in the Trust Fund.)


No.: A-1A	Date: August 29, 2006	CUSIP: 66988X AN 4

Original Principal Balance: $505,563,000	Registered Owner: CEDE & CO.	Final Scheduled Distribution Date: September 25, 2036

Percentage Interest: 100%	Pass-Through Rate: LIBOR + 0.1500%

The registered owner named above is the registered owner of a fractional interest in (i) each Group I Mortgage Loan identified on the Mortgage Loan Schedule attached as Exhibit B to that certain Pooling and Servicing Agreement dated as of August 1, 2006 (the “Pooling and Servicing Agreement”) by and among NovaStar Mortgage Funding Corporation, as the depositor (the “Depositor”), Deutsche Bank National Trust Company, as trustee (the “Trustee”), U.S. Bank National Association, as the custodian (the “Custodian”), and NovaStar Mortgage, Inc. as servicer (the “Servicer”) and as sponsor (the “Sponsor”), including the related

Cut-off Date Principal Balance, all interest accruing thereon on and after the Cut-off Date and all collections in respect of interest and principal due after the Cut-off Date; (ii) property which secured each such Mortgage Loan and which has been acquired by foreclosure or deed in lieu of foreclosure; (iii) the Depositor’s interest in any insurance policies in respect of such Mortgage Loans; (iv) all proceeds of any of the foregoing; (v) the rights of the Depositor under the Purchase Agreement and (vi) all other assets included or to be included in the Trust Fund. Such assignment includes all interest and principal due to the Depositor or the Servicer after the Cut-off Date with respect to the Mortgage Loans.

The Original Principal Amount set forth above is equal to the product of (i) the Percentage Interest represented by this Certificate and (ii) the aggregate Original Principal Amount of the Class A-1A Certificates on August 29, 2006 which aggregate amount was $505,563,000. The owner hereof is entitled to principal payments on each Distribution Date, which will fully amortize such Original Principal Amount over the period from the date of initial delivery hereof to the final Distribution Date of the Class A-1A Certificates. Therefore, the actual outstanding principal amount of this Certificate, on any date subsequent to September 25, 2006 (the first Distribution Date) will be less than the Original Principal Amount set forth above.

In order to receive the final distribution hereon, the owner hereof is required to present this Certificate to the Trustee. The Pooling and Servicing Agreement provides that, in any event, upon the making of the final distribution due on this Certificate, this Certificate shall be deemed cancelled for all purposes under the Pooling and Servicing Agreement.

SOLELY FOR FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE REPRESENTS AN INTEREST IN A CLASS OF “REGULAR INTERESTS” IN A “REAL ESTATE MORTGAGE INVESTMENT CONDUIT” (“REMIC”) AS THOSE TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”), ASSUMING COMPLIANCE WITH THE REMIC PROVISIONS (SECTIONS 860A THROUGH 860G) OF THE CODE.

THIS CERTIFICATE IS A PASS-THROUGH CERTIFICATE ONLY AND, NOTWITHSTANDING REFERENCES HEREIN TO PRINCIPAL AND INTEREST, NO DEBT OF ANY PERSON IS REPRESENTED HEREBY (OTHER THAN AS REQUIRED FOR FEDERAL INCOME TAX PURPOSES).

NEITHER THIS CERTIFICATE NOR THE MORTGAGE LOANS ARE INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE GOVERNMENT NATIONAL MORTGAGE ASSOCIATION OR ANY OTHER GOVERNMENTAL AGENCY.

Terms capitalized herein and not otherwise defined herein shall have the respective meanings set forth in the Pooling and Servicing Agreement.

On the 25th day of each month, or, if such day is not a Business Day, then the next succeeding Business Day (each such day being a “Distribution Date”) commencing September 25, 2006, the owners of the Class A-1A Certificates as of the close of business on the business day immediately preceding such Distribution Date (the “Record Date”) will be entitled to the distribution described in Article IV of the Pooling and Servicing Agreement, relating to such Distribution Date.

The Trustee is required to duly and punctually pay distributions with respect to this Certificate in accordance with the terms hereof and the Pooling and Servicing Agreement. Amounts properly withheld under the Code or applicable to any owner shall be considered as having been paid by the Trustee to such owner for all purposes of the Pooling and Servicing Agreement.

The Mortgage Loans will be serviced by the Servicer pursuant to the Pooling and Servicing Agreement. The Pooling and Servicing Agreement permits the Servicer to enter into Sub-Servicing Agreements with certain institutions eligible for appointment as Sub-Servicers for the servicing and administration of certain Mortgage Loans.

Notwithstanding any other provisions in the Pooling and Servicing Agreement, the owner of any Certificate shall have the right which is absolute and unconditional to receive distributions to the extent provided in the Pooling and Servicing Agreement with respect to such Certificate or to institute suit for the enforcement of any such distribution, and such right shall not be impaired without the consent of such owner.

The Pooling and Servicing Agreement will terminate upon notice to the Trustee upon the earliest of (i) the Distribution Date on which the Certificate Principal Balances of the Regular Certificates have been reduced to zero, (ii) the final payment or other liquidation of the last Mortgage Loan held by the Issuing Entity, (iii) the optional purchase by the Servicer of the Mortgage Loans as described below, (iv) the Distribution Date in September 2036 and (v) at any time when a Qualified Liquidation of the Master REMIC and REMIC I, REMIC II, REMIC III and REMIC IV is effected pursuant to the Pooling and Servicing Agreement.

		institution), partnership, or Massachusetts or similar business trust; or (viii) an investment advisor registered under the Investment Advisors Act of 1940, as amended, which, for each of (i) through (viii), owns and invests on a discretionary basis at least $100 million in securities other than securities of issuers affiliated with the Transferee, securities issued or guaranteed by the United States or a person controlled or supervised by and acting as an instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States, bank deposit notes and certificates of deposit, loan participations, repurchase agreements, securities owned but subject to a repurchase agreement, and currency, interest rate and commodity swaps (collectively, “Excluded Securities”);

—		a dealer registered pursuant to Section 15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that in the aggregate owns and invests on a discretionary basis at least $10 million of securities other than Excluded Securities and securities constituting the whole or part of an unsold allotment to, or subscription by, Transferee as a participant in a public offering;

—		an investment company registered under the Investment Company Act that is part of a family of investment companies (as defined in Rule 144A of the Securities and Exchange Commission) which own in the aggregate at least $100 million in securities other than Excluded Securities and securities of issuers that are part of such family of investment companies;

That the Investor intends to pay such taxes associated with holding the Class R Certificates as they become due.

Formula Test] That the Investor agrees that the present value of the anticipated tax liabilities associated with holding the Class R Certificates does not exceed the sum of the present value of any consideration given to the Investor to acquire the Class R Certificates, the present value of the expected future distributions on the Class R Certificates, and the present value of the anticipated tax savings associated with holding the interest as the REMIC generates losses. That the Investor agrees that it complied with U.S. Treasury Regulations Section 1.860E-1(c)(8) in making such representation.

That the Investor determined the consideration paid to it to acquire the Class R Certificates in good faith and based on reasonable market assumptions (including, but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax rates and other factors specific to the Investor).

8. That the Investor is a citizen or resident of the United States, a corporation, partnership or other entity created or organized in, or under the laws of, the United States or any political subdivision thereof, or an estate or trust whose income from sources without the United States is includable in gross income for United States federal income tax purposes regardless of its connection with the conduct of a trade or business within the United States.
