The Escrow Agent will deposit such cash proceeds of the offering of Certificates by a Trust (each, a “Deposit” and, together, the “Deposits”) with Citibank, N.A., as depositary (the “Depositary”), in accordance with a Deposit Agreement relating to such Trust (each, a “Deposit Agreement” and, together, the “Deposit Agreements”), and will withdraw

(z) The Company maintains “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) under the Exchange Act) that comply with the requirements of the Exchange Act; such disclosure controls and procedures have been designed to ensure that material information relating to the Company is made known to the Company’s principal executive officer and principal financial officer by others within the Company; and such disclosure controls and procedures are effective to perform the functions for which they were established; the Company’s auditors and the audit committee of the board of directors of the Company have been advised of: (i) any significant deficiencies or material weaknesses in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize, and report financial data; and (ii) any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal controls; and since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities would not, singly or in the aggregate, have a Material Adverse Effect, except as set forth in or contemplated in the Time of Sale Prospectus and the Prospectus (exclusive of any supplement thereto).

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action or proceeding (including any governmental investigation), such indemnified party will, if a claim for indemnification in respect thereof is to be made against the indemnifying party under Section 7(a) or (b) hereof, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party (i) will not relieve such indemnifying party from liability under Section 7(a) or (b) hereof, unless and to the extent such indemnifying party did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any case, relieve it from any liability that it may have to any indemnified party otherwise than under Section 7(a) or (b) hereof. In case any such action or proceeding 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 (jointly with any other indemnifying party similarly notified), and to the extent that it may elect, by written notice, delivered to such 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; provided, however, that if the defendants (including any impleaded parties) in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to defend 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 appoint counsel to defend such action and approval by the indemnified party of such counsel, 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 (x) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expense of more than one separate counsel (in addition to any local counsel), approved by the Underwriters in the case of paragraph (a) of this Section 7, representing the indemnified parties under such paragraph (a) who are parties to such action), (y) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice or commencement of the action or (z) 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 (x) or (z) is applicable, such liability shall be only in respect of the counsel referred to in such clause (x) or (z). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld), but if settled with such consent or if there is a final judgment against the indemnified party, 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 by the proviso of the second sentence and the third sentence of this paragraph, the

indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (1) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request, (2) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (3) 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 (which consent shall not be unreasonably withheld), 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 (A) does not include a statement as to or admission of, fault, culpability or a failure to act by or on behalf of any such indemnified party, and (B) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in paragraph (a) or (b) of this Section 7 is due in accordance with its terms but is for any reason unavailable on grounds of policy or otherwise, the Company and the Underwriters shall contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigation or defending same) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other, from the offering of the Certificates to which such loss, claim, damage, or liability (or action in respect thereof) relates. If the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable to such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company 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 (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Certificates pursuant to this Agreement shall be deemed to be in the same proportion as the total proceeds from the offering of the Certificates pursuant to this Agreement (before deducting expenses) received by the Company as set forth in the Prospectus and the total underwriting discounts and commissions received or to be received by the Underwriters in respect of the offering of the Certificates, bears to the aggregate offering price of the Certificates as set forth on the cover of the Prospectus. 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 Company or such Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include 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 subsection (d), no Underwriter shall be required to contribute hereunder in aggregate any amount in excess of the underwriting discount or commission actually paid to such Underwriter in connection with the transactions contemplated hereby less the aggregate amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to

contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls any Underwriter within the meaning of either the Section 15 of the Securities Act or Section 20 of the Exchange Act and each broker-dealer affiliate of any Underwriter shall have the same rights to contribution as any Underwriter, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, each officer of the Company and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the provisions of this paragraph (d). The obligations of the Underwriters of Certificates in this subsection (d) to contribute are several in proportion to their respective purchase obligations with respect to such Certificates and not joint.

8. Default. (a) If any Underwriter shall default in its obligation to purchase the Certificates which it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Certificates on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Certificates, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Certificates on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Certificates, or the Company notifies you that it has so arranged for the purchase of such Certificates, you or the Company shall have the right to postpone the Closing Time for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Prospectus, or in any other documents or arrangements, and the Company agrees to prepare promptly any amendments to the Prospectus which in your reasonable opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Certificates.

(b) If, after giving effect to any arrangements for the purchase of the Certificates of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of Certificates which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Certificates, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Certificates which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Certificates which such Underwriter agreed to purchase hereunder) of the Certificates of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Certificates of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of Certificates which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Certificates, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Certificates of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 5 hereof and the indemnity and contribution agreements in Section 7 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

9. Termination. This Agreement shall be subject to termination in your discretion, by notice given to the Company prior to Closing Time, if prior to such time (i) trading in the Company’s common stock shall have been suspended by the Commission or The NASDAQ Global Select Market, or trading in securities generally on The NASDAQ Stock Market or the New York Stock Exchange shall have been suspended or materially limited or minimum prices shall have been established on any such

exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities, (iii) there shall have occurred any material 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 your reasonable judgment, impracticable or inadvisable to market the Certificates or to enforce contracts for sale of the Certificates, or (iv) there shall have occurred any material disruption in securities settlement, payment or clearance services in the United States that would materially impair settlement and clearance with respect to the Certificates.

10. Representations, Warranties, Indemnities and Agreements to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Underwriters, as set forth in or made pursuant to this Agreement shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by the Underwriters or any controlling person of any Underwriter or the Company or any officer or director or controlling person of the Company and shall survive delivery of and payment for the Certificates.

11. Liability upon Termination. If this Agreement shall be terminated pursuant to Section 8 or 9 hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 5 and 7 hereof; but, if for any other reason, the Certificates are not delivered by or on behalf of the Company as provided herein, because the Company fails to satisfy any of the conditions set forth in Section 4 hereof or because of any refusal, inability or failure of the Company to perform any agreement herein or to comply with any provision hereof, other than by reason of a default by the Underwriters, the Company will reimburse the Underwriters for all out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Certificates, but the Company shall then be under no further liability to any Underwriter with respect to such Certificates except as provided in Section 5 and Section 7 hereof.

12. Notices. It is understood and agreed that ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC and Citigroup Global Markets Inc. are joint lead book runners for the public offering of the Certificates and any determinations or other actions to be made under this Agreement by you shall require the concurrence of each of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC and Citigroup Global Markets Inc. All statements, requests, notices and agreements hereunder shall be in writing and, if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to each of you, at ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC, ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: Equipment Finance Group, and Citigroup Global Markets Inc., ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: Global Structured Debt – Capital Markets, and, if to the Company, shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Prospectus, Attention: General Counsel. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

13. Parties. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Sections 7 and 10 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Certificates from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

14. Time of the Essence. Time shall be of the essence of this Agreement.

15. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Certificates pursuant to this Agreement, including the determination of the offering price of the Certificates and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction each

Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, or its stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of each of the Company, and (e) the Underwriters have 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 it deemed appropriate.

16. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

17. Entire Agreement. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

18. GOVERNING LAW. THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK.

19. Waiver of Jury Trial. The Company and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

20. Counterparts. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

If the foregoing is in accordance with your understanding, please sign and return to us counterparts hereof, and upon the acceptance hereof by you, this letter and such acceptance hereof shall constitute a binding agreement between each of the Underwriters and the Company.
