On the Delivery Date, the Depositor will convey the Mortgage Loans to the Issuing Party pursuant to the Pooling and Servicing Agreement. The Certificates are more fully described in the Registration Statement (as such term is defined in Section 2(a)), which the Depositor has furnished to the Underwriters.

This Underwriting Agreement (this “Agreement”) includes the terms and conditions governing the offering and sale of Certificates from the Depositor to the Underwriters. Upon the execution and delivery of this Agreement, the Representative and the other Underwriters identified on Schedule II hereto agree to become obligated to purchase Certificates from the Depositor.

2. Representations and Warranties of the Depositor. The Depositor represents and warrants to each of the Underwriters as of the date hereof and as of the Delivery Date:

(a) A registration statement on Form S-3 (File Number 333-______), including such amendments thereto as may have been required on the date hereof relating to the Certificates, has been filed with the Securities and Exchange Commission (the “Commission”) and such registration statement, as amended, has become effective under the Securities Act of 1933 (the “Act”). Such registration statement, as amended to the date of this Agreement meets the requirements set forth in Rule 415(a)(1) under the Act and complies in all other material respects with such rule. Such registration statement, as amended and all documents incorporated therein by reference relating to the Certificates is hereinafter referred to as the “Registration Statement.” A prospectus (the “Base Prospectus”) and prospectus supplement with respect to the offering of the Certificates (the “Prospectus Supplement”) shall be filed with the Commission pursuant to Rule 424 (b) of the rules and regulations of the Commission promulgated under the Act (the “Rules and Regulations”) shall be collectively referred to herein as the “Prospectus.” References made herein to the Prospectus also shall be deemed to include any documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act as of the date of the Prospectus, and any reference to any amendment or supplement to the Prospectus shall be deemed to include any document filed under the Securities Exchange Act of 1934 (the “Exchange Act”) after the date of the Prospectus and incorporated by reference in the Prospectus and any reference to any amendment to the Registration Statement shall be deemed to include any report of the Depositor filed with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act after the Effective Time (as defined below) that is incorporated by reference in the Registration Statement.

(b) The Depositor proposes to file with the Commission pursuant to Rule 424 under the Act a Prospectus Supplement relating to the Certificates and the plan of distribution thereof and has previously advised the Underwriters of all information (financial and other) with respect to the Depositor to be set forth therein. The Commission has not issued any order preventing or suspending the use of the Prospectus or the effectiveness of the Registration Statement and no proceedings for such purpose are pending or, to the Depositor’s knowledge, threatened by the Commission. There are no contracts or documents of the Depositor that are required to be filed as exhibits to the Registration Statement pursuant to the Act or the Rules and Regulations which have not been so filed or incorporated by reference therein on or prior to the Effective Date of the Registration Statement. The conditions to the use of a registration statement on Form S-3 under the Act, as set forth in the General Instructions to Form S-3, and the conditions of Rule 415 under the Act, have been satisfied with respect to the Registration Statement. For purposes of this Agreement, “Effective Time” means the date and time as of which such registration statement, or the most recent post-effective amendment thereto (if any) filed prior to the execution and delivery of this Agreement, was declared effective by the Commission and “Effective Date” means the date of the Effective Time.

(l) Each Underwriter covenants with the Depositor that after the final Prospectus is available each of the Underwriters shall not distribute any written information concerning the Certificates to a prospective investor of Certificates unless

-13-

such information is preceded or accompanied by the Prospectus or the required notice pursuant to Rule 173 of the Act has been delivered.

5. Covenants of the Depositor. The Depositor covenants and agrees with the Underwriters participating in the offering of the Certificates that:

(a) Immediately following the execution of this Agreement, the Depositor will prepare a Prospectus Supplement setting forth the amount of Certificates and the terms thereof not otherwise specified in the Base Prospectus, the price at which such Certificates are to be purchased by the Underwriters, from the Depositor, either the initial public offering price or the method by which the price at which such Certificates are to be sold will be determined, the selling concessions and reallowances, if any, and such other information as the Underwriters and the Depositor deem appropriate in connection with the offering of such Certificates, but the Depositor will not file, for so long as the delivery of a Prospectus is required in connection with the offering or sale of such Certificates, any amendments to the Registration Statement as in effect with respect to such Certificates, or any amendments or supplements to the related Prospectus, unless it shall first have delivered copies of such amendments or supplements to the Underwriters, or if the Underwriters shall have reasonably objected thereto promptly after receipt thereof, the Depositor will, during such period, immediately advise the Underwriters or their counsel (i) when notice is received from the Commission that any post-effective amendment to the Registration Statement has become or will become effective and (ii) of any order or communications suspending or preventing, or threatening to suspend or prevent, the offer and sale of the Certificates or of any proceedings or examinations that may lead to such an order or communication, whether by or of the Commission or any authority administering any state securities or Blue Sky law, as soon as the Depositor is advised thereof, and will use its best efforts to prevent the issuance of any such order or communication and to obtain as soon as possible its lifting, if issued. The Depositor will use its best efforts to prevent the issuance of any stop order suspending the effectiveness of the Registration Statement and, if issued, to obtain as soon as possible the withdrawal thereof. The Depositor will file such Prospectus pursuant to Rule 424 under the Act not later than the Commission’s close of business on the second Business Day following the availability of the Prospectus to the Underwriters.

(b) If, at any time when a Prospectus relating to the Certificates is required to be delivered under the Act, any event occurs as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend or supplement the Prospectus to comply with the Act or the Rules and Regulations, the Depositor will promptly prepare and file with the Commission, an amendment or supplement that will correct such statement or omission or an amendment that will effect such compliance.

(c) The Depositor will cause any Free Writing Prospectuses with respect to the Certificates to be filed with the Commission pursuant to Rule 433 under the Act in accordance with Section 8 prior to the time of filing of the Prospectus as provided in Section 5(a) hereof and will include therein all such materials so furnished; provided,

-14-

however, the Depositor shall only be responsible for the filing of a Free Writing Prospectus prepared by the Underwriters as described in Section 4(f) hereof to the extent delivered by the Underwriters within the time period specified in Section 4(f) hereof.

(d) The Depositor will cause the Trust Administrator to furnish or make available, within a reasonable time after the end of each calendar year, to each holder of a Certificate (each, a “Certificateholder”) at any time during such year, such information as is necessary or desirable to assist Certificateholders in preparing their federal income tax returns.

(e) The Depositor will furnish to the Underwriters copies of the Registration Statement (two of which will be signed and will include all documents and exhibits thereto or incorporated by reference therein), the Prospectus, the Time of Sale Offering Document, and all amendments and supplements to such documents relating to the Certificates, in each case as soon as available, and in such quantities as the Underwriters reasonably request.

(f) The Depositor will arrange for, and will pay all expenses (including reasonable fees and expenses of counsel) in connection with the qualification of the Certificates for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Underwriters designate and will continue such qualifications in effect so long as required for the distribution of the Certificates; provided, however, that neither the Depositor nor the Issuing Entity shall be required to do business in any jurisdiction where it is now not qualified or to take any action which would subject it to general or unlimited service of process in any jurisdiction in which it is now not subject to service of process.

(g) The Depositor will, while the Certificates are outstanding, furnish to the Underwriters information with respect to the related Issuing Entity or the Mortgage Loans included in the related mortgage pool, as any such Underwriter may reasonably request, including but not limited to information necessary or appropriate to the maintenance of a secondary market in the Certificates.

(h) The Depositor, whether or not the transactions contemplated under this Agreement are consummated or this Agreement is terminated, will pay all expenses incident to the performance of its obligations under this Agreement and will reimburse the Underwriters for any expenses (excluding fees and disbursements of its counsel, any Underwriter due diligence of the Mortgage Loans and accounting comfort letters obtained in connection with any Free Writing Prospectus other than any Issuer Free Writing Prospectus) incurred by them in connection with (i) the offering and the qualification of the Certificates, (ii) the preparation of all documents described herein, including any Issuer Free Writing Prospectus, (iii) reasonable fees and expenses of the Servicer, Subservicer, Owner Trustee, Indenture Trustee and Trust Administrator, (iv) the determination of their eligibility for investment under the laws of such jurisdictions as the Underwriters may designate and the reproduction of memoranda relating thereto, (v) any fees charged by investment rating agencies for the rating of the Certificates and (vi) reasonable and customary expenses incurred in distributing any Prospectus and the Time of Sale Offering Document or any amendments or supplements thereto to the

-15-

Underwriters; provided however, that the Depositor shall not be liable for the payment of any of the foregoing amounts to the extent that the failure to consummate the transactions described herein resulted from any act or omission of the Underwriters pursuant to the terms of this Agreement.

(i) During the period when a Prospectus is required by law to be delivered in connection with the sale of Certificates pursuant to this Agreement, the Depositor will file, or cause the Trust Administrator to file on behalf of the related Issuing Entity, on a timely and complete basis, all documents that are required by the related Issuing Entity with the Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act.

6. Conditions to the Obligations of the Underwriters. The obligations of the Underwriters to purchase and pay for the Certificates subject to this Agreement will be subject to the accuracy of the representations and warranties on the part of the Depositor as of the date hereof, and the applicable Delivery Date, to the performance by the Depositor in all material respects of its obligations hereunder and to the following additional conditions precedent:

(k) The Underwriters shall have received a statement of counsel to the Depositor substantially to the effect that nothing has come to such counsel’s attention that would lead them to believe that the Registration Statement (at the time it became effective), the Prospectus or the Prospectus Supplement (in both cases, as of the date of

(w) There shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations, subsequent to the execution and delivery of this Agreement, of the Seller and its affiliates that is in the reasonable judgment of the Underwriters material and adverse and that makes it in the reasonable judgment of the Underwriters impracticable to market the Certificates on the terms and in the manner contemplated in the Prospectus.

7. Indemnification.

(a) The Depositor will indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, expenses, damages or liabilities (including the cost of any investigation, legal and other expenses incurred in connection with and amounts paid settlement of any action, suit, proceeding or claim asserted) to which such Underwriter or such controlling person may become subject, under the Act or the Exchange Act or other Federal or State statutory law or otherwise, insofar as such losses, claims, expenses, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Free Writing Prospectus or Issuer Free Writing Prospectus in the Approved Offering Materials, any Static Pool Information, or the Registration Statement or the Prospectus or any amendment or supplement thereto, 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 not misleading (which, in respect of information included in the Approved Offering Materials, was not corrected by the Corrective Information subsequently supplied to the Underwriters at any time prior to the Time of Sale); and will reimburse each Underwriter and each such controlling person for any legal or other expenses reasonably incurred by such Underwriter and each such controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided however, that the Depositor or any affiliate will 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 any such untrue statement or alleged untrue statement in or omission or alleged omission made in any such documents (A) in reliance upon and in conformity with any Derived Information and (B) in any Free Writing Prospectus furnished to prospective investors by the Underwriters, except to the extent that any untrue statement or alleged untrue statement therein or omission

-22-

therefrom results directly from an error (a “Mortgage Pool Error”) in the information concerning the characteristics of the Mortgage Loans or any Issuer Information, in each case, furnished by the Seller or the Depositor to any Underwriter in writing or by electronic transmission that was used in connection with either (x) any Free Writing Prospectus or (y) any written or electronic materials furnished to prospective investors on which any Free Writing Prospectus was based, or except to the extent that any untrue statement or alleged untrue statement in or omission from any Free Writing Prospectus is caused primarily by information contained in the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement of any of them, taking into account information incorporated therein by reference including Static Pool Information. This indemnity agreement will be in addition to any liability which the Depositor may otherwise have.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Depositor, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Depositor within the meaning of Section 15 of the Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnities from the Depositor to each Underwriter, but only with reference to (i) any Derived Information provided by such Underwriter (except resulting from a Mortgage Pool Error) in any Free Writing Prospectus or Issuer Free Writing Prospectus and (ii) the Prospectus or any amendment or supplement thereto, or arise out of, or are based upon, the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein not misleading, but with respect to clause (b)(ii) above, only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with any Underwriters’ Information; provided, however, that in no event shall the Underwriters be liable to the Depositor under this paragraph (b) with respect to material described in clause (i) above unless such Underwriter prepared such Derived Information and no Underwriter shall be liable to the Depositor under this paragraph (b) in an amount in excess of the underwriting discounts and commissions received by such Underwriter in connection with this offering of the Certificates. This indemnity agreement will be in addition to any liability that such Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof, but the omission to so notify the indemnifying party will not relieve the indemnifying party from any liability which the indemnifying party may have to any indemnified party hereunder except to the extent such indemnifying party has been prejudiced thereby. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying

-23-

party). After notice from the indemnifying party to such indemnified party of its election to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof , unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) for each of, and approved by, the Underwriters in the case of paragraph (a) of this Section 7, representing the related indemnified parties under such paragraph (a) who are parties to such action), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability shall only be in respect of the counsel referred to in such clause (i) or (iii). No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 any claims that are the subject matter of such action. In no event shall an indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Depositor on the one hand and the Underwriters on the other from the offering of the 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 the relative benefits referred to in clause (i) above but also the relative fault of the Depositor on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Depositor on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Depositor bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault 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 Depositor or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or

-24-

liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified in connection with investigating or defending any action or claim which is the subject to this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of underwriting discounts and commissions received by such Underwriter. 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 Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(iv) The Depositor shall not be required to file (A) Issuer Information contained in any Free Writing Prospectus of an Underwriter or any other offering participant other than the Depositor, if such information is included or incorporated by reference in the Prospectus, any Issuer Free Writing Prospectus or any Free Writing Prospectus previously filed with the Commission that relates to the offering of the Certificates, or (B) any Free Writing Prospectus or portion thereof that contains no Issuer Information but contains a description of the Certificates or the offering of the Certificates which does not reflect the final terms thereof;

provided, that prior to such use of any Free Writing Prospectuses by the Depositor, the Underwriters must comply with their obligations pursuant to Section 4 and that the Depositor shall not be required to file any Free Writing Prospectus that does not contain substantive changes from or additions to a Free Writing Prospectus previously filed with the Commission.

(c) Any “written communication” (as defined in Rule 405 under the Act) prepared by or on behalf of the Underwriters to be designated as “Approved Offering Materials” in the Pricing Supplement must be delivered to the Depositor and its counsel, no later than the business day prior to the proposed date of first use thereof. The Depositor must consent to prior to any such “written communication” being designated as “Approved Offering Materials” in the Pricing Supplement.

9. Default of Underwriters. If any Underwriter or Underwriters participating in the offering of Certificates default in their obligations to purchase Certificates hereunder and the aggregate principal amount of such Certificates which such defaulting Underwriter or Underwriters agreed, but failed, to purchase does not exceed 10% of the total principal amount of the Certificates set forth in the Pricing Supplement, the Underwriters may make arrangements satisfactory to the Depositor for the purchase of such Certificates by other persons, including any of the Underwriters participating in such offering, but regardless of whether such arrangements are made the non-defaulting Underwriters shall remain obligated severally to purchase the Certificates which they committed to purchase in accordance with the terms hereunder. If any Underwriter or Underwriters so default and the aggregate principal amount of the Certificates with respect to which such default or defaults occur is more than 10% of the total principal amount of the Certificates set forth in the Pricing Supplement and arrangements satisfactory to the Underwriters and the Depositor for the purchase of such Certificates by other persons are not made, this Agreement will terminate without liability on the part of any nondefaulting Underwriters, except as provided in Section 7. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Termination of the Obligations of the Underwriters. The obligations of the Underwriters to purchase the Certificates on the related Delivery Date shall be terminable by the Underwriters if at any time on or prior to the Delivery Date (a) any of the conditions set forth in Section 6 are not satisfied when and as provided therein; (b) the Underwriters and the Depositor

are unable to agree on a new Purchase Price following an event described in Section 4(k)(iv) hereof; (c) there shall have been the entry of a decree or order by a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a conservator, receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to any Seller or the Depositor, or for the winding up or liquidation of the affairs of any Seller or the Depositor; or (d) there shall have been the consent by the related Seller or the Depositor to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the related Seller or the Depositor or of or relating to substantially all of the property of the related Seller or the Depositor. The termination of the Depositor’s obligations hereunder shall not terminate the Depositor’s rights hereunder or its right to exercise any remedy available to it at law or in equity.

Notwithstanding anything herein contained, this Agreement shall be subject to termination in the absolute discretion of the Underwriters, by notice given to the Depositor prior to delivery of and payment for the Certificates, if prior to such time (i) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall have been declared by Federal or state authorities or (iii) there shall have occurred any outbreak or material escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States is such as to make it, in the reasonable judgment of the Underwriters, impracticable to market the Certificates.

11. No Fiduciary Duty.

(a) The Depositor acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Depositor with respect to the offering of the Certificates contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Depositor or any other person. In addition, no Underwriter is advising the Depositor or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Depositor shall consult with its own advisors concerning such matters, and the Underwriters shall have no responsibility or liability to the Depositor with respect thereto.

(c) The Depositor acknowledges and agrees that it has been advised that the Underwriters and their respective affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Depositor and that the

-27-

Underwriters are under no obligation to disclose such interests and transactions to the Depositor by virtue of any fiduciary, advisory or agency relationship.

(d) The Depositor hereby waives, to the fullest extent permitted by law, any claims it may have against the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty, and the Depositor hereby agrees that the Underwriters shall have no liability, directly or indirectly, to the Depositor in respect of such fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Depositor.

12. Survival of Certain Indemnities, Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements by the Depositor or its officers, each Seller or its respective officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriters, the Depositor or any Seller or any of their officers or directors or any controlling person, and will survive delivery of and payment for the Certificates.

If this Agreement is terminated pursuant to Section 10 or if for any reason the purchase of the Certificates by the Underwriters is not consummated, the Depositor shall remain responsible for the expenses to be paid or reimbursed by them pursuant to Section 5(h), and the obligations of the Depositor and the Underwriters pursuant to Section 7 shall remain in effect.

13. Notices. All communications hereunder will be in writing and, if sent to an Underwriter, will be mailed, delivered or telegraphed and confirmed to the Underwriters as follows: (a) for [________________________], and (b) [__________________________], and to the Depositor at 000 Xxxxxx Xxxxxx, Xxxxxxxx, Xxxxxxxx 00000 (Telecopy Number: 804-___-____), Attention: President.

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors and controlling persons referred to in Section 7, and their successors and assigns, and no other person will have any right or obligations hereunder.

15. Applicable Law. THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW).

16. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

17. Obligations of the Seller. The Seller agrees with each of the Underwriters, for the sole and exclusive benefit of each such Underwriter, each such Underwriter’s officers and directors and each person controlling each such Underwriter within the meaning of the Act, and not for the benefit of any assignee thereof or any other person or persons dealing with such Underwriter as follows: in consideration of and as an inducement to their agreement to purchase the Certificates from the Depositor, to indemnify and hold harmless each Underwriter against

-28-

any failure by the Depositor to perform its obligations to the Underwriters hereunder, including, without limitation, any failure by the Depositor to honor any obligation to any Underwriter pursuant to Section 7 hereof. In the case of any claim against the Seller by any Underwriter, any officer or director of any Underwriter or any person controlling any Underwriter, it shall not be necessary for such claimant to first pursue any remedy from or exhaust any procedures against the Depositor.
