A. The Depositor has filed with the Securities and Exchange Commission (the “Commission”) a registration statement (No. 333-131111) on Form S-3 for the registration under the Securities Act of 1933, as amended (the “Act”), of asset backed securities (issuable in series), which registration statement, as amended at the date hereof, has become effective.

and in connection with the determination of the eligibility of the Underwritten Certificates for investment under the laws of such jurisdictions as the Underwriters may reasonably designate, if any.

(4) the Underwritten Certificates have been duly executed, authenticated and delivered by the Trustee and assuming delivery and payment are validly issued therefor and outstanding and are entitled to the benefits of the Pooling and Servicing Agreement; and

(5) the execution and delivery of, and performance by the Trustee of its obligations under, the Basic Documents to which it is a party do not conflict with or result in a violation of any statute or regulation applicable to the Trustee, or the charter or bylaws of the Trustee, or to the best knowledge of such counsel, any governmental authority having jurisdiction over the Trustee or the terms of any indenture or other agreement or instrument to which the Trustee is a party or by which it is bound.

In rendering such opinion, such counsel may rely, as to matters of fact, on certificates of responsible officers of the Sponsor, the Depositor, the Trustee and public officials. Such opinion may also assume the due authorization, execution and delivery of the instruments and documents referred to therein by the parties thereto other than the Trustee.

M. The Underwriters shall have received such opinion or opinions, dated the Closing Date, with respect to (i) the “true sale” of the Mortgage Loans from the Sponsor to the Depositor and from the Depositor to the Issuing Entity and (ii) the “non-consolidation” in a bankruptcy proceeding of the Sponsor and the Depositor, in form and substance reasonably satisfactory to the Underwriters.

N. The Underwriters shall have received from McKee Nelson LLP, special counsel to the Underwriters, such opinion or opinions, dated the Closing Date, with respect to the issuance and sale of the Underwritten Certificates, the Prospectus and such other related matters as the Underwriters shall reasonably require.

O. The Underwriters shall have received an opinion from Dewey Ballantine LLP, special tax counsel to the Depositor to the effect that the statements in the Pricing Free Writing Prospectus, the Prospectus and the Prospectus Supplement under the heading “Material Federal Income Tax Consequences” accurately describe the material federal income tax consequences to the holders of the Underwritten Certificates and that the statements under the heading “ERISA Considerations” in the Prospectus and the Prospectus Supplement, are materially correct, to the extent such statements purport to state or summarize matters of federal law.

P. Each Cap Agreement will be delivered by the applicable NovaStar Entity to the Trustee. Each Cap Agreement shall have been duly authenticated by an authorized agent of the related Cap Counterparty, if so required under applicable state law or regulations.

Q. The Underwriters and their counsel shall have received copies of any opinions of counsel to the NovaStar Entities or the Trustee supplied to the Trustee relating to matters with respect to the Certificates or the acquisition of the Mortgage Loans. Any such opinions shall be satisfactory to the Underwriters in form and substance.

R. The Underwriters shall have received a negative assurance letter with respect to the Pricing Free Writing Prospectus from each of Dewey Ballantine LLP and McKee Nelson LLP.

S. The Underwriters and their counsel shall have received such further information, certificates and documents as the Underwriter may reasonably have requested not fewer than three (3) full business days prior to the Closing Date.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all respects when and as provided in this Agreement, if the NovaStar entities are in breach of any

covenants or agreements contained herein or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Underwriters and their counsel, this Agreement and all obligations of the Underwriters hereunder, may be canceled on, or at any time prior to, the Closing Date by the Underwriters. Notice of such cancellation shall be given to the Sponsor and the Depositor in writing, or by telephone or telegraph confirmed in writing.

7. No Advisory or Fiduciary Responsibility. Each of the Sponsor and the Depositor acknowledges and agrees that: (i) the purchase and sale of the Underwritten Certificates pursuant to this Agreement, including the determination of the public offering price of the Underwritten Certificates and any related discounts and commissions, is an arm’s-length commercial transaction between the Sponsor and the Depositor, on the one hand, and the several Underwriters, on the other hand, and the Sponsor and the Depositor are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Sponsor, the Depositor or their respective affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Sponsor or the Depositor with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Sponsor or the Depositor on other matters) or any other obligation to the Sponsor or the Depositor except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Sponsor and the Depositor and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Sponsor and the Depositor have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

A. Regardless of whether any Underwritten Certificates are sold, the Sponsor, the Depositor and NFI will jointly and severally indemnify and hold harmless each Underwriter, each of their respective officers and directors and each person who controls each Underwriter within the meaning of the Act or the Securities Exchange Act of 1934 (the “1934 Act”), against any and all losses, claims, damages, or liabilities (including the cost of any investigation, legal and other expenses incurred in connection with and amounts paid in settlement of any action, suit, proceeding or claim asserted), joint or several, to which they may become subject, under the Act, the 1934 Act or other federal or state law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein (in the case of the Registration Statement) or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading in,

(i) the Registration Statement, or any amendment thereof or supplement thereto, (ii) the Basic Prospectus, the Prospectus Supplement, the Pricing Free Writing Prospectus or the Static Pool Data, whether or not incorporated therein by reference or any amendment thereto or supplement thereto, or (iii) the Sponsor-Provided Information, and will reimburse each such indemnified party for any legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action; provided, however, that the Sponsor, the Depositor and NFI shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with the Underwriter Information.

B. Regardless of whether any Underwritten Certificates are sold, each Underwriter, severally and not jointly, will indemnify and hold harmless the Sponsor, the Depositor, NFI and each of its officers and directors and each person, if any, who controls the Sponsor, the Depositor and NFI within the meaning of the Act or the 1934 Act against any losses, claims, damages or liabilities to which they become subject under the Act, the 1934 Act or other federal or state law or regulation, at common law or otherwise, to the same extent as the foregoing indemnity, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Prospectus Supplement or in the Pricing Free Writing Prospectus or any amendment thereto or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made therein in reliance upon and in conformity with the Underwriter Information provided by such Underwriter, and will reimburse the Sponsor, the Depositor and NFI for any legal or other expenses reasonably incurred by the Sponsor, the Depositor and NFI in connection with investigating or defending against such loss, claim, damage, liability or action.

C. In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to paragraphs A, B and E of this Section 8, such person (hereinafter called the indemnified party) shall promptly notify the person against whom such indemnity may be sought (hereinafter called the indemnifying party) in writing thereof; provided, however, that the failure to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure; and provided further, however, that the failure to notify any indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 8. The indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, or (ii) the named parties to any such

proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties, and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the applicable Underwriter in the case of parties indemnified pursuant to paragraph A of this Section 8 and by the Sponsor, the Depositor and NFI in the case of parties indemnified pursuant to paragraphs B and E of this Section 8. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated above, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(1) All Marketing Materials, to the extent required to be filed with the Commission, shall be filed as free writing prospectuses.

(2) Each of the Underwriters may convey Derived Information (as defined below) (x) to a potential investor prior to entering into a Contract of Sale with such investor; provided, however, that such Underwriter shall not enter into a Contract of Sale with such investor unless such Underwriter has conveyed the Pricing Free Writing Prospectus to such potential investor prior to such Contract of Sale and such Derived Information shall be conveyed separate and apart from any Pricing Free Writing Prospectus and (y) to an investor after a Contract of Sale provided that such Underwriter has conveyed the Pricing Free Writing Prospectus to such investor in connection with such Contract of Sale. Each of the Underwriters agrees that it shall not broadly disseminate any Derived Information.

(3) Each of the Underwriters agrees to provide to the Depositor prior to the date of filing of the Pricing Free Writing Prospectus a copy of any Derived Information conveyed by such Underwriter if such Derived Information is in fact required to be filed under the Act, and the Depositor shall file such Derived Information with the Commission if the filing is in fact required under the Act.

(4) Each of the Underwriters may convey Issuer Marketing Materials (as defined below), or Traditional Marketing Materials (as defined below) to a potential investor prior to entering into a Contract of Sale with such investor; provided, however, that such Underwriter shall not enter into a Contract of Sale with such investor unless such Underwriter has conveyed the Pricing Free Writing Prospectus to such potential investor prior to such Contract of Sale. In addition, in the case of Traditional Marketing Materials, such Underwriter shall (x) deliver a copy of the Traditional Marketing Materials to the Depositor and its counsel one business day prior to the first use thereof, (y) shall not convey any such Traditional Marketing Materials to which the Depositor or its counsel reasonably objects and (z) shall convey such Traditional Marketing Materials to each potential investor in the class or classes of Offered Notes to which such Traditional Marketing Materials relates.

(5) Each Underwriter that has furnished Issuer Marketing Materials or Traditional Marketing Materials, in each instance, other than those that contain only ABS ICM (as defined below), to potential investors shall furnish copies thereof to the Depositor at the time of first use thereof, and the Depositor shall file such Issuer Marketing Materials or Traditional Marketing Materials, as applicable, with the Commission if the filing thereof is in fact required under the Act. Each Underwriter that has furnished Issuer Marketing Materials or Traditional Marketing Materials, in each instance, that contain only ABS ICM, to potential investors shall furnish copies thereof to the Depositor prior to the date of filing of the Prospectus Supplement, and the Depositor shall file such Issuer Marketing Materials or Traditional Marketing Materials, as applicable, with the Commission if the filing thereof is in fact required under the Act.

(6) Notwithstanding any provision of this Section 8 to the contrary, unless required under the Act, no Underwriter shall be required to file with the Commission or deliver to the Depositor for filing with the Commission any free writing prospectus that (i) is used or referred to by it and distributed by or on behalf of it in a manner that is not reasonably designed to lead to its broad, unrestricted dissemination and (ii) does not consist of or include Issuer Marketing Materials or Traditional Marketing Materials.

E. Each Underwriter agrees, severally and not jointly, assuming all Sponsor -Provided Information (defined below) is accurate and complete in all material respects, to indemnify and hold harmless the Sponsor and the Depositor, their respective officers and directors and each person who controls the Sponsor within the meaning of the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they may become subject under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement of a material fact contained in the Derived Information provided by such Underwriter, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by him, her or it in connection with investigating or defending or preparing

to defend any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that this indemnity shall not apply to any untrue statement or omission or alleged untrue statement or alleged omission made in any Derived Information that results from an error or omission in any Sponsor-Provided Information. The several obligations of each Underwriter under this Section 8(E) shall be in addition to any liability which each Underwriter may otherwise have.

The procedures set forth in Section 8(C) shall be equally applicable to this Section 8(E).

F. If the indemnification provided for in this Section 8 is unavailable to an indemnified party in respect of any losses, claims, damages or liabilities referred to herein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Sponsor, the Depositor, NFI and the Underwriters from the sale of the Underwritten Certificates or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only relative benefits referred to in clause (i) above but also the relative fault of the Sponsor, the Depositor, NFI and of the Underwriters in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.

The relative benefits received by an Underwriter shall be equal to its aggregate discount and underwriting commissions with respect to the Underwritten Certificates purchased by such Underwriter, and the relative benefits of the Sponsor, the Depositor and NFI shall be equal to the balance of the proceeds of the sale of the Offered Notes; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The relative fault of the Sponsor, the Depositor, NFI and each Underwriter shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Sponsor, the Depositor, NFI or by any of the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

G. The Sponsor, the Depositor, NFI and each Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph F of this Section 8. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph F of this Section 8 shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the aggregate discount and underwriting commissions with respect to the Underwritten Certificates purchased by it less amounts such Underwriter has already been required to pay by reason of the untrue or alleged untrue statement or omission or alleged omission.

H. The Sponsor, the Depositor and each Underwriter each expressly waive, and agree not to assert, any defense to their respective indemnification and contribution obligations under this Section 8 which they might otherwise assert based upon any claim that such obligations are unenforceable under federal or state securities laws or by reasons of public policy.

I. The obligations of the Sponsor and the Depositor under this Section 8 shall be in addition to any liability which the Sponsor and the Depositor may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Underwriter within the meaning of the Act or the 1934 Act; and the several obligations of the Underwriters under this Section 8 shall be in addition to any liability that the Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Sponsor and to each person, if any, who controls the Sponsor within the meaning of the Act or the 1934 Act; provided, however, that in no event shall the Sponsor, the Depositor or the Underwriters be liable for double indemnification.

(1) “ABS ICM” means “ABS informational and computational materials” as defined in Item 1101(a) of Regulation AB of the Act (“Regulation AB”) promulgated by the Commission.

(2) “Bloomberg Submission” means the material provided by or through Bloomberg or Intex or similar entities for use by prospective investors, or embedded in any CDI files provided to prospective investors.

(3) “Collateral Strats” means information regarding the Mortgage Loans that is based on the Sponsor-Provided Information that is conveyed separate and apart from any Preliminary Term Sheet.

(6) “Issuer Marketing Materials” means Marketing Materials that include “issuer information” as defined in Rule 433(h)(2) of the Act that are required to be filed by the Depositor under the Act.

(8) “Preliminary Term Sheet” means a “written communication” within the meaning of Rule 405 under the Act that describes the Notes and/or the Mortgage Loans and contains information described in paragraphs (1) – (3) of the definition of ABS Informational and Computational Materials in Item 1101(a) of Regulation AB but which does not include Derived Information.

(9) “Sponsor-Provided Information” means any computer tape furnished to any Underwriter by the Sponsor concerning the assets comprising the Trust.

(10) “Static Pool Data” means any information provided by the Depositor as contemplated by Item 1105 of Regulation AB relating to securitized pools established by the Sponsor.

(11) “Traditional Marketing Materials” means Marketing Materials that are required to be filed under the Act that contain both “issuer information” as defined in Rule 433(h)(2) of the Act and other information that would be required to be filed under the Act, other than Collateral Strats and Bloomberg Submissions.

9. Information Supplied by Underwriters. The first sentence of the last paragraph on the front cover page of the Supplement, the third paragraph under the heading “Method of Distribution” in the Supplement and the fifth paragraph on the cover page of the Supplement (the “Underwriter Information”) constitute the only information furnished by the Underwriters to the Sponsor and the Depositor for the purposes of Sections 2(B), 8(A) and 8(B) hereof. Each Underwriter confirms that the Underwriter Information relating to it is correct as of the date of the Prospectus Supplement.

11. Survival. All representations, warranties, covenants and agreements of the Sponsor and the Depositor contained herein or in agreements or certificates delivered pursuant hereto, and the agreements of the Underwriters, the Sponsor and the Depositor contained in Section 8 hereof shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Underwriters or any controlling persons, or any subsequent purchaser or the Sponsor or the Depositor or any of its officers, directors or any controlling persons, and shall survive delivery of and payment for the Underwritten Certificates. The provisions of Sections 5 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Termination.

14. APPLICABLE LAW; VENUE. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.
