9. Indemnification and Contribution. The Company agrees with the Underwriter that:

(a) The Company will indemnify and hold harmless the Underwriter[, Selected Dealers] and each Person who controls the Underwriter [or any Selected Dealer] within the meaning of either the 1933 Act or the 1934 Act against any and all losses, claims, damages or liabilities, joint or several, to which the Underwriter [or such Selected Dealer] may become subject under the 1933 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 any untrue statement or alleged untrue statement of a material fact contained in (w) any Derived Information disseminated by the Underwriter [or such Selected Dealer], (x) any information, other than Derived Information, in any Prospectus disseminated by the Underwriter [or such Selected Dealer], (y) the Registration Statement or in any amendment thereof, or the omission or alleged omission to state in the Registration Statement or any amendment thereof a material fact required to be stated therein or necessary to make the statements therein not misleading, or (z) any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, the Preliminary Prospectus or the Final Prospectus, or the omission or alleged omission to state in the Base Prospectus, the Preliminary Prospectus or the Final Prospectus or in any amendment or supplement thereto a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and agrees to reimburse such indemnified party for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however , that (i) the Company

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 or omission or alleged omission made therein in reliance upon and in conformity with (A) the information in each of the Preliminary Prospectus Supplement and the Final Prospectus Supplement contained under the headings [ ] or (B) written information furnished to the Company as herein stated by the Underwriter specifically for use in connection with the preparation thereof and in any Free Writing Prospectus other than a misstatement or omission arising from a misstatement or omission in the information provided by the Company concerning the assets of the Trust (such information, the “Company Provided Information”), and (ii) such indemnity with respect to the Base Prospectus or the Preliminary Prospectus shall not inure to the Underwriter [or any Selected Dealer] or any Person controlling the Underwriter [or such Selected Dealer] from which the Person asserting any such loss, claim, damage or liability purchased the Offered Certificates that are the subject thereof, if such Person did not receive a copy of the Final Prospectus at or prior to the confirmation of the sale of such Offered Certificates to such Person in any case where such delivery is required by the 1933 Act and the untrue statement or omission of a material fact contained in the Base Prospectus or in any such Preliminary Prospectus was corrected in the Final Prospectus. This indemnity will be in addition to any liability that the Company may otherwise have.

(b) The Underwriter agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each Person, if any, who controls the Company within the meaning of either the 1933 Act or the 1934 Act, to the same extent as the foregoing indemnity from the Company to the Underwriter, but only with reference to written information furnished to the Company as herein stated by the Underwriter specifically for use in connection with the preparation of the documents referred to in the foregoing indemnity or in any Free Writing Prospectus except to the extent that such misstatement or omission arises from a misstatement or omission in the Company Provided Information. This indemnity will be in addition to any liability that the Underwriter may otherwise have. The Company and the Underwriter acknowledges that the Underwriter Information constitutes the only information furnished in writing by the Underwriter for inclusion in the documents referred to in the foregoing indemnity, and the Underwriter confirms that such statements are correct.

(c) Promptly after receipt by an indemnified party under this Section 9 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 9, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party otherwise than under this Section 9. 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 satisfactory to such indemnified party; provided, however , that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party or parties shall have reasonably concluded that there may be legal defenses available to it or them and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to elect separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable 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, approved by the Underwriter in the case of paragraph (a) of this Section 9), (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).

(d) If the indemnification provided for in this Section 9 shall for any reason be unavailable to an indemnified party under this Section 9, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the aggregate option due losses, claims, damages and liabilities referred to in paragraph (a) or (b) above, in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Offered Certificates or, if the allocation referred to above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company on the one hand and the Underwriter 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; provided, however , that the Underwriter shall not be responsible for more than the amount of its underwriting discounts and commissions; and provided, further , that no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any Person that was not guilty of such fraudulent misrepresentation. For purposes of this Section 9, a Person, if any, that controls the Underwriter within the meaning of either the 1933 Act or the 1934 Act shall have the same rights to contribution as does the Underwriter and each Person, if any, that controls the Company within the meaning of either the 1933 Act or the 1934 Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this paragraph (d), notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this paragraph (d).

10. Termination.

(a) This Agreement shall be subject to termination in the Underwriter’s absolute discretion, by notice given to the Company prior to delivery of and payment for the Offered Certificates, if, prior to such time, (i) trading of securities generally on the New York Stock Exchange or the American Stock Exchange shall have been suspended or materially limited, (ii) a general moratorium on commercial banking activities in New York shall have been declared by either federal or New York State authorities or (iii) there shall have occurred any material outbreak or declaration 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 Underwriter’s reasonable judgment, impracticable to market the Offered Certificates on the terms specified herein.

(b) If the sale of the Offered Certificates shall not be consummated because any condition to the obligations of the Underwriter set forth in Section 8 hereof is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of the default of the Underwriter, the Company shall reimburse the Underwriter for the reasonable fees and expenses of the Underwriter’s counsel and for such other out-of-pocket expenses as shall have been incurred by the Underwriter in connection with this Agreement and the proposed purchase of the Offered Certificates, and upon demand the Company shall pay the full amount thereof to the Underwriter.

(c) This Agreement will survive delivery of and payment for the Offered Certificates. The provisions of Section 6, Section 9 and this Section 10(c) shall survive the termination or cancellation of this Agreement.

11. No Advisory or Fiduciary Responsibility. The Company acknowledges and agrees that: (i) the purchase and sale of the Offered Certificates pursuant to this Agreement, including the determination of the public offering price of the Offered Certificates and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Underwriter, and the Company is 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 the Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or its affiliates, stockholders, creditors or employees or any other party; (iii) except as otherwise provided in this

Agreement, the Underwriter has not assumed or will not assume an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement; (iv) the Underwriter and its respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the Underwriter has no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriter has not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriter, or any of them, with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriter with respect to any breach or alleged breach of an agency or fiduciary duty not set forth in this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Underwriter, will be mailed, delivered or transmitted by facsimile and confirmed to [ ], [ ], attention: [ ]; and if sent to the Company, will be mailed, delivered or transmitted by facsimile and confirmed to it at [ ], attention: [ ].

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling Persons referred to in Section 9, and their successors and assigns, and no other Person will have any right or obligation hereunder.

14. Applicable Law; Counterparts. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without reference to its conflict of law provisions (other than Section 5-1401 of the general obligations law), and the obligations, rights and remedies of the parties hereunder shall be determined in accordance with such laws. This Agreement may be executed in any number of counterparts, each of which shall for all purposes be deemed to be an original and all of which shall together constitute but one and the same instrument.

If the foregoing is in accordance with the Underwriter’s understanding of our agreement, please sign and return to us a counterpart hereof, whereupon this letter and the Underwriter’s acceptance shall represent a binding agreement between the Company and the Underwriter.
