(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 of the NovaStar Mortgage Funding Trust, Series 2006-5, relating to the NovaStar Home Equity Loan Asset-Backed Certificates, Series 2006-5,” 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;

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

(vii) an executed copy of the notice of assignment and acknowledgement of assignment with respect to the Mortgage Loans covered by the MI Policies.

If a 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 (as pledgee of the Mortgage Loans), 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 (i) 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, 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 hereof as to the Initial Mortgage Loans and the Subsequent Mortgage Loans and Section 2.02(c) hereof as to the Subsequent Mortgage Loans for breaches of representations and warranties.

Promptly after the Closing Date in the case of an Initial Mortgage Loan, or, in the case of a Subsequent Mortgage Loan, promptly after the Subsequent Transfer Date (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 an Initial Mortgage Loan or, in the case of a Subsequent Mortgage Loan, prior to or on the Subsequent Transfer Date, 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 Initial Mortgage Loan registered on the MERS System, promptly after the Closing Date, the Sponsor further agrees that it will cause, at the Sponsor’s own expense, the MERS System to indicate that such Initial Mortgage Loan has been assigned by the Sponsor to the Trustee in accordance with this Agreement for the benefit of the Certificateholders by including in such computer files (a) the applicable Trustee code in the field “Trustee” which identifies the Trustee and (b) the code “NovaStar 2006-5” (or its equivalent) in the field “Pool” which identifies the series of the Certificates issued in connection with such Mortgage Loans. The Custodian will certify in its final certification that the MERS System shows the Trustee on behalf of the Certificateholders as the beneficial owner of the Mortgage Loans registered on the MERS System.

Effective on the Closing Date, the Depositor hereby acknowledges its acceptance of all right, title and interest to the Initial 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 Initial 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 this Purchase Agreement. The Pooling and Servicing Agreement shall provide that any late payment charges collected in connection with a Mortgage Loan shall be paid to the Servicer as provided therein.

(lxxxvii) The sale, transfer, assignment and conveyance of Mortgage Loans by the Sponsor pursuant to this Purchase Agreement is not subject to and will not result in any tax, fee or governmental charge payable by the Depositor, the Custodian or the Trustee to any federal, state or local government (“Transfer Taxes”) other than Transfer Taxes which have or will be paid by the Sponsor as due;

(lxxxviii) Each Mortgage Loan is a “qualified mortgage” within Section 860G(a)(3) of the Code;

(lxxxix) Approximately 55.86% of the Initial Mortgage Loans (by Cut-off Date Principal Balance) with a Loan-to-Value Ratio greater than 60% are covered by an MI Policy issued by an MI Insurer;

(xc) Approximately 55.86% of the Initial Mortgage Loans that are identified on Exhibit 1 hereto are covered by a MI Policy issued by an MI Insurer;

(xci) All requirements for the valid transfer of each MI Policy, including any assignments or notices required in each MI Policy, have been satisfied;

(xcii) As of the Closing Date with respect to each Initial Mortgage Loan that is subject to a MI Policy and as of each Subsequent Transfer Date with respect to each Subsequent Mortgage Loan that is subject to a MI Policy, the Sponsor is unaware of any existing circumstances which would cause the MI Insurer to deny a claim with respect to such Mortgage Loan;

(xciii) All appraisals of the Mortgage Loans by the Sponsor are full URAR/1004 appraisals;

(xciv) All Prepayment Charges are enforceable and were originated in compliance with all applicable federal, state, and local laws;

(xcvi) With respect to mortgage loans that are more than 59 days delinquent as of the Cut-off Date, the Sponsor has made a specific review of the Servicer’s data and records that reflect mortgagor communications and payment history, and has no actual knowledge of an event, condition or mortgagor communication which would cause the Sponsor to institute foreclosure proceedings;

(xcvii) The servicer for each Group I Mortgage Loan has fully furnished (and will fully furnish), in accordance with the Fair Credit Reporting Act and its implementing regulations, accurate and complete information (i.e., favorable and unfavorable) on its borrower credit files to Equifax, Experian, and Trans Union Credit Information Company (three of the credit repositories), on a monthly basis;

(xcviii) None of the Group I Mortgage Loans are classified as (a) “high cost” loans under the Home Ownership and Equity Protection Act of 1994 or (b) “high cost,” “threshold,” “covered”, “predatory” or “abusive” loans under any other applicable state, federal or local law (including without limitation any regulation or ordinance) (or a similarly classified loan using different terminology under a law imposing heightened regulatory scrutiny or additional legal liability for residential mortgage loans having high interest rates, points and/or fees);

(xcix) With respect to any Group I Mortgage Loan originated on or after August 1, 2004, neither the related mortgage nor the related mortgage note requires the borrower to submit to arbitration to resolve any dispute arising out of or relating in any way to the mortgage loan transaction;

(c) With respect to any Group I Mortgage Loan, the borrower was not encouraged or required to select a mortgage loan product offered by the mortgage loan’s originator which is a higher cost product designed for less creditworthy borrowers, taking into account such facts as, without limitation, the mortgage loan’s requirements and the borrower’s credit history, income, assets and liabilities. For each Group I Mortgage Loan, with respect to a borrowers seeking financing through a mortgage loan originator’s higher-priced subprime lending channel, such borrower was directed towards or offered the mortgage loan originator’s standard mortgage line if the borrower was able to qualify for one of the standard products;

(ci) With respect to any Group I Mortgage Loan, the methodology used in underwriting the extension of credit for each Group I Mortgage Loan did not rely solely on the extent of the borrower’s equity in the collateral as the principal determining factor in approving such extension of credit. The methodology employed objective criteria such as the borrower’s income, assets and liabilities, to the proposed mortgage payment and, based on such methodology, the mortgage loan’s originator made a reasonable determination that at the time of origination the borrower had the ability to make timely payments on the mortgage loan;

(cii) With respect to any Group I Mortgage Loan, no borrower was charged “points and fees” in an amount greater than (a) $1,000 or (b) 5% of the principal amount of such Mortgage Loan, whichever is greater. For purposes of this representation, “points and fees” (x) include origination, underwriting, broker and finder’s fees and charges that the lender imposed as a condition of making the mortgage loan, whether they are paid to the lender or a third party; and (y) exclude bona fide discount points, fees paid for actual services rendered in connection with the origination of the mortgage (such as attorneys’ fees, notaries fees and fees paid for property appraisals, credit reports, surveys, title examinations and extracts, flood and tax certifications, and home inspections); the cost of mortgage insurance or credit-risk price adjustments; the costs of title, hazard, and flood insurance policies; state and local transfer taxes or fees; escrow deposits for the future payment of taxes and insurance premiums; and other miscellaneous fees and charges, which miscellaneous fees and charges, in total, do not exceed 0.25% of the loan amount;

(ciii) For each Group I Mortgage Loan, with respect to any subordinate lien Mortgage Loan, such lien is on a one- to four-family residence that is the principal residence of the borrower;

(civ) For each Group I Mortgage Loan, no subordinate lien Mortgage Loan has an original principal balance that exceeds one-half of the one-unit limitation for first lien mortgage loans, i.e., $208,500 (in Alaska, Guam, Hawaii or Virgin Islands: $312,750), without regard to the number of units;

(cv) For each Group I Mortgage Loan, the original principal balance of the first lien mortgage loan plus the original principal balance of any subordinate lien mortgage loans relating to the same mortgaged property does not exceed the applicable loan limit for first lien mortgage loans for that property type (as set out in clause (lxxix) above);

(cvi) There is no Group I Mortgage Loan that is “seasoned”, where the date of the mortgage note is more than 1 year before the date of issuance of the related Certificates.

Upon discovery by the Sponsor or upon notice from the Depositor, the Trustee, or the Custodian, as applicable, of a breach of any representation or warranty in subsection (a) of this Section which materially and adversely affects the interests of the Certificateholders the Sponsor shall, within 45 days of its discovery or its receipt of notice of such breach, either (i) cure such breach in all material respects or (ii) to the extent that such breach is with respect to a Mortgage Loan or a Related Document, either (A) repurchase such Mortgage Loan from the Trustee at the Repurchase Price, or (B) substitute one or more Eligible Substitute Mortgage Loans for such Mortgage Loan, in each case in the manner and subject to the conditions and limitations set forth below.

Upon discovery by the Sponsor or upon notice from the Depositor, the Trustee, or the Custodian, as applicable, of a breach of any representation or warranty in this subsection (b) with respect to any Mortgage Loan or upon the occurrence of a Repurchase Event, which

materially and adversely affects the value of the related Mortgage Loan or the interests of any Certificateholders or of the Depositor or the Trustee in such Mortgage Loan (notice of which shall be given to the Depositor and the Trustee by the Sponsor, if it discovers the same) the Sponsor shall, within 90 days after the earlier of its discovery or receipt of notice thereof, either cure such breach or Repurchase Event in all material respects or either (i) repurchase such Mortgage Loan from the Trustee at the Repurchase Price, or (ii) substitute one or more Eligible Substitute Mortgage Loans for such Mortgage Loan, in each case in the manner and subject to the conditions set forth below; provided, however, that a breach of any of the representations and warranties found in subsections b(xx), (b)(lii), (b)(lxii), (b)(lxvii), (b)(lxxiv), (b)(lxxv), (b)(lxxix), (b)(xcvii), (b)(xcviii) and (b)(xcix) shall be deemed to materially and adversely affect the interest of the Certificateholders. The Repurchase Price for any such Mortgage Loan repurchased by the Sponsor shall be deposited or caused to be deposited by the Servicer in the Collection Account maintained by it pursuant to Section 3.06 of the Pooling and Servicing Agreement.

In the event that the Sponsor elects to substitute an Eligible Substitute Mortgage Loan or Loans for a Deleted Mortgage Loan pursuant to this Section 3.01, the Sponsor shall deliver to the Custodian on behalf of the Trustee, with respect to such Eligible Substitute Mortgage Loan or Loans, the original Mortgage Note and all other documents and agreements as are required by Section 2.01 hereof, with the Mortgage Note endorsed as required by such Section 2.01 hereof. No substitution will be made in any calendar month after the Determination Date for such month. Monthly Payments due with respect to Eligible Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the Servicer and remitted by the Servicer to the Sponsor on the next succeeding Payment Date. For the month of substitution, distributions to the Collection Account pursuant to the Pooling and Servicing Agreement will include the Monthly Payment due on a Deleted Mortgage Loan for such month and thereafter the Sponsor shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Servicer shall amend or cause to be amended the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan and the substitution of the Eligible Substitute Mortgage Loan or Loans and the Servicer shall deliver the amended Mortgage Loan Schedule to the Custodian and the Trustee. Upon such substitution, the Eligible Substitute Mortgage Loan or Loans shall be subject to the terms of this Purchase Agreement and the Pooling and Servicing Agreement in all respects, the Sponsor shall be deemed to have made the representations and warranties with respect to the Eligible Substitute Mortgage Loan contained herein set forth in this Section 3.01(b), to the extent set forth in the definition of “Eligible Substitute Mortgage Loan”, as of the date of substitution, and the Sponsor shall be obligated to repurchase or substitute for any Eligible Substitute Mortgage Loan as to which a Repurchase Event has occurred as provided herein. In connection with the substitution of one or more Eligible Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Servicer will determine the amount (such amount, a “Substitution Adjustment Amount”), if any, by which (i) the Repurchase Price that would otherwise apply to such Deleted Mortgage Loan, exceeds (ii) the principal balance of the related Eligible Substitute Mortgage Loan (after application of the principal portion of the Monthly Payments due in the month of substitution that are to be distributed to the Collection Account in the month of substitution). The Sponsor shall pay the amount of such shortfall to the Servicer for deposit into the Collection Account on the day of substitution, without any reimbursement therefor.

Upon receipt by the Trustee of written notification, signed by a Servicing Officer, of the deposit of such Repurchase Price or of such substitution of an Eligible Substitute Mortgage Loan and deposit of any applicable Substitution Adjustment Amount as provided above, the Custodian shall, on behalf of the Trustee, cause to be released to the Sponsor the related Mortgage File for the Mortgage Loan being repurchased or substituted for and the Trustee shall execute and deliver such instruments of transfer or assignment prepared by the Servicer, in each case without recourse, as shall be necessary to vest in the Sponsor or its designee such Mortgage Loan released pursuant hereto and thereafter such Mortgage Loan shall not be an asset of the Trustee.

It is understood and agreed that the obligation of the Sponsor to cure any breach with respect to or to repurchase or substitute for, any Mortgage Loan as to which such a breach has occurred and is continuing shall, except to the extent provided in Section 6.01 of this Purchase Agreement, constitute the sole remedy respecting such breach available to the Depositor, the Trustee, the Certificateholders or the Custodian against the Sponsor.

It is understood and agreed that the representations and warranties set forth in this Section 3.01 shall survive delivery of the respective Mortgage Files to the Custodian on behalf of the Trustee.

The Depositor hereby represents and warrants to the Sponsor and the Trustee as of the date hereof and as of the Closing Date that:

(a) The Depositor is duly organized and validly existing as a corporation in good standing under the laws of the State of Delaware, with power and authority to own its properties and to conduct its business as such properties are currently owned and such business is presently conducted.

(c) The Depositor has the power and authority to execute and deliver this Purchase Agreement and to carry out its terms; the Depositor has full power and authority to purchase the property to be purchased from the Sponsor and the Depositor has duly authorized such purchase by all necessary corporate action; and the execution, delivery and performance of this Purchase Agreement have been duly authorized by the Depositor by all necessary corporate action.

The Sponsor shall indemnify and hold harmless the Depositor, Trustee and the Custodian from and against any loss, liability or expense arising from the breach by the Sponsor of its representations and warranties in Section 3.01 of this Purchase Agreement which materially and adversely affects the value of any Mortgage Loan or the Depositor’s assignees’ interest in any Mortgage Loan or from the failure by the Sponsor to perform its obligations under this Purchase Agreement in any material respect.

None of the directors, officers, employees or agents of the Sponsor shall be under any liability to the Depositor, it being expressly understood that all such liability is expressly waived and released as a condition of, and as consideration for, the execution of this Purchase Agreement. Except as and to the extent expressly provided in the Basic Documents, the Sponsor shall not be under any liability to the Trustee, the Custodian or the Certificateholders.

other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriters, impracticable to market the Offered Certificates or to enforce contracts for the sale of the Offered Certificates, or

(iii) if trading in any securities of the Sponsor has been suspended or limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the NASDAQ National Market System has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority,

If this Purchase Agreement is terminated pursuant to this Section 7.01(b), such termination shall be without liability of any party to any other party except as provided in Section 4.02 hereof.

This Purchase Agreement may be amended from time to time by the Sponsor, the Depositor, the Trustee and the Custodian by written agreement signed by the Sponsor, the Depositor, the Trustee and the Custodian.

This Purchase Agreement shall be governed by and construed in accordance with the laws of the State of New York and the obligations, rights and remedies of the parties hereunder shall be determined in accordance with such laws.

All demands, notices and communications hereunder shall be in writing and shall be deemed to have been duly given if personally delivered at or mailed by registered mail, postage prepaid, addressed as follows:

Nothing herein contained shall be deemed or construed to create a partnership or joint venture between the parties hereto, and the services of the Sponsor shall be rendered as an independent contractor and not as agent for the Depositor.

This Purchase Agreement may be executed in two or more counterparts and by the different parties hereto on separate counterparts, each of which, when so executed, shall be deemed to be an original and such counterparts together shall constitute one and the same agreement.

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

It is the intention of the parties that (i) the Depositor is purchasing on the Closing Date, and the Sponsor is selling on the Closing Date, the Initial Mortgage Loans, rather than the Depositor providing to the Sponsor a loan secured by the Initial Mortgage Loans on the Closing Date, and (ii) the Trustee is purchasing on the Closing Date, and the Depositor is selling on the Closing Date, the Initial Mortgage Loans, rather than the Trustee providing to the Depositor a loan secured by the Initial Mortgage Loans, and (iii) the Depositor will be purchasing on each Subsequent Transfer Date, and the Sponsor will be selling on each Subsequent Transfer Date, the related Subsequent Mortgage Loans, rather than the Depositor providing to the Sponsor a loan secured by the related Subsequent Mortgage Loans on each Subsequent Transfer Date, and (iv) the Trustee will be purchasing on each Subsequent Transfer Date, and the Depositor will be selling on each Subsequent Transfer Date, the related Subsequent Mortgage Loans, rather than the Trustee providing to the Depositor a loan secured by the related Subsequent Mortgage Loans on each Subsequent Transfer Date. Accordingly, the parties hereto each intend to treat these transactions as (i) a sale by the Sponsor, and a purchase by the Depositor, of the Initial Mortgage Loans on the Closing Date, and (ii) a sale by the Depositor, and a purchase by the Trustee, of the Initial Mortgage Loans on the Closing Date, (iii) a sale by the Sponsor, and a purchase by the Depositor, of the related Subsequent Mortgage Loans on each Subsequent Transfer Date, and (iv) a sale by the Depositor, and a purchase by the Trustee, of the related Subsequent Mortgage Loans on each Subsequent Transfer Date.

This Purchase Agreement shall bind and inure to the benefit of and be enforceable by the Sponsor, the Depositor, the Trustee, the Custodian, and their respective successors and assigns. The obligations of the Sponsor under this Purchase Agreement cannot be assigned or delegated to a third party without the consent of the Depositor, which consent shall be at the Depositor’s discretion. The parties hereto acknowledge that (i) the Depositor is acquiring the Initial Mortgage Loans for the purpose of selling them to the Trustee, who will hold the Initial Mortgage Loans in trust for the benefit of the Certificateholders and (ii) the Depositor is acquiring the Subsequent Mortgage Loans for the purpose of selling them to the Trustee. who will hold the Subsequent Mortgage Loans for the benefit of the Certificateholders. As an inducement to the Depositor and the Trustee to purchase the Mortgage Loans, the Sponsor acknowledges and consents to (i) the assignment by the Depositor to the Trustee of all of the Depositor’s rights or remedies against the Sponsor pursuant to this Purchase Agreement and to (ii) the enforcement or exercise of any rights against the Sponsor pursuant to this Purchase Agreement by the Depositor and the Trustee. Such enforcement of a right or remedy by the Trustee, shall have the same force and effect as if the right or remedy had been enforced or exercised by the Depositor directly.

The representations and warranties made herein by the Sponsor and the provisions of Article V hereof shall survive the purchase of the Mortgage Loans hereunder.

The Trustee is entering into the Basic Documents to which it is a party solely as Trustee, hereunder and thereunder, and not in its individual capacity, and all persons having any claim against the Trustee by reason of the transactions contemplated by this Agreement or any other Basic Document shall look only to the Trust Fund for payment or satisfaction thereof.

IN WITNESS WHEREOF, the Sponsor, the Depositor, the Custodian and the Trustee have caused their names to be signed to this Mortgage Loan Purchase Agreement by their respective officers thereunto duly authorized as of the day and year first above written.

Pursuant to this Sponsor’s Subsequent Transfer Instrument (the “Sponsor’s Instrument”), dated as of , 200 , between NovaStar Mortgage, Inc. as sponsor (the “Sponsor”), and NovaStar Mortgage Funding Corporation, as depositor (the “Depositor”), and pursuant to the Mortgage Loan Purchase Agreement, dated as of September 1, 2006 (the “Purchase Agreement”), among the Sponsor, the Depositor, U.S. Bank National Association, as Custodian (the “Custodian”) and Deutsche Bank National Trust Company, as Trustee (the “Trustee”), the Sponsor and the Depositor agree to the sale by the Sponsor and the purchase by the Depositor of the subsequent Mortgage Loans listed on the attached Mortgage Loan Schedule (the “Subsequent Mortgage Loans”) and the related MI Policies.

Capitalized terms used and not defined herein have their respective meanings as set forth in the definitions contained in the Pooling and Servicing Agreement, dated as of September 1, 2006 (the “Pooling and Servicing Agreement”), between the Trustee, the Custodian, the Depositor and the Sponsor/Servicer which definitions are incorporated by reference herein. All other capitalized terms used herein shall have the meanings specified herein.

(a) The Sponsor does hereby sell, transfer, assign, set over and convey to the Depositor, without recourse, all of its right, title and interest in and to the Subsequent Mortgage Loans and the related MI Policies, all scheduled payments of principal and interest on the Subsequent Mortgage Loans due after the Subsequent Cut-off Date, and all other payments of principal and interest on the Subsequent Mortgage Loans collected after the Subsequent Cut-off Date (minus that portion of any such payment which is allocable to the period prior to the Subsequent Cut-off Date); provided, however, that no scheduled payments of principal and interest due on or before the Subsequent Cut-off Date and collected after the Subsequent Cut-off Date shall belong to the Depositor pursuant to the terms of this Sponsor’s Instrument. The Sponsor, contemporaneously with the delivery of this Sponsor’s Instrument, has delivered or caused to be delivered to the Custodian, at the direction of the Depositor, each item set forth in Section 2.02(b) of the Purchase Agreement with respect to such Subsequent Mortgage Loans and the related MI Policies.

In the event the transactions set forth herein shall be deemed not to be a sale, the Sponsor hereby grants to the Depositor as of the Subsequent Transfer Date a security interest in all of the Sponsor’s right, title and interest in, to and under the Subsequent Mortgage Loans, and such other property, to secure all of the Sponsor’s obligations
