The Basic Agreement, as supplemented by the Trust Supplement, is defined as the “Designated Agreement.”

          The Certificates will represent interests in the Trust established pursuant to the Designated Agreement to fund the purchase of (i) Series B Equipment Notes (as defined in the

Existing Indentures referred to herein, as amended by the related Indenture Amendments referred to herein) to be issued by the Company in connection with the financing of 12 aircraft owned by the Company and set forth on Schedule V hereto (each such aircraft, a “Funded Aircraft” and, collectively, the “Funded Aircraft”) and (ii) Series B Equipment Notes (as defined in the Note Purchase Agreement referred to herein) to be issued by the Company in connection with the financing of 16 aircraft owned by the Company and set forth on Schedule VI hereto (each such aircraft, a “Pre-Funded Aircraft” and, collectively, the “Pre-Funded Aircraft”).

          With respect to the Funded Aircraft, subject to the terms and conditions of the Designated Agreement and the relevant Participation Agreement, dated as of December 21, 2010 (each, an “Existing Participation Agreement” and, collectively, the “Existing Participation Agreements”), among the Company, the Class A Trustee (as defined in the Original Intercreditor Agreement referred to herein), U.S. Bank Trust, as subordination agent (the “Subordination Agent”), U.S. Bank Trust, as loan trustee (the “Loan Trustee”), and U.S. Bank Trust, in its individual capacity as expressly set forth therein, and each as amended by the related First Amendment to Participation Agreement (each, a “Participation Agreement Amendment” and collectively, the “Participation Agreement Amendments”), to be dated as of the day of the Closing Time (as defined below), among the Company, the Class A Trustee, the Trustee, the Subordination Agent, the Loan Trustee and U.S. Bank Trust, in its individual capacity as expressly set forth therein , Series B Equipment Notes will be issued under 12 separate Indenture and Security Agreements, each dated as of December 21, 2010 (each, including any supplements thereto, an “Existing Indenture” and, collectively, the “Existing Indentures”), between the Company and the Loan Trustee, and each as amended by the related First Amendment to Indenture and Security Agreement (each, an “Indenture Amendment” and collectively, “Indenture Amendments”), dated as of day of the Closing Time, between the Company and Loan Trustee.

          A portion of the cash proceeds of the offering of Certificates by the Trust will be applied at the Closing Time to purchase the Series B Equipment Notes in respect of the Funded

Aircraft. The remaining portion of the cash proceeds of the offering of Certificates by the Trust will be paid to the Escrow Agent, under an Escrow and Paying Agent Agreement (Class B), dated as of the day of the Closing Time, among the Escrow Agent, you, the Trustee and the Paying Agent, for the benefit of the holders of Certificates issued by the Trust (the “Escrow Agreement”).

With respect to each Certificate, the Escrow Agent will issue a receipt to be attached to such Certificate (each, an “Escrow Receipt”) representing a fractional undivided interest of the holder of such Certificate in amounts deposited with the Depository on behalf of the Escrow Agent and will pay to such holders through the Paying Agent interest accrued on the Deposits and received by such Paying Agent pursuant to the Deposit Agreement at a rate per annum equal to the interest rate applicable to such Certificate.

          (b) To file no amendment or any supplement to the Registration Statement, the Preliminary Prospectus or the Prospectus prior to the Closing Time to which you reasonably object promptly after reasonable notice thereof; to advise you, promptly after it receives notice thereof, of the time when any amendment to the Registration Statement has been filed or becomes effective or any amendment or supplement to the Prospectus has been filed and to furnish you with copies thereof; to prepare a final term sheet containing solely a description of the Certificates, in a form approved by you and to file such term sheet pursuant to Rule 433(d) under the Act within the time required by such Rule; to timely file all other material required to be filed by the Company with the Commission pursuant to Rule 433(d) under the Act; to timely file all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Act) (the “Prospectus Delivery Period”) is required in connection with the offering or sale of the Certificates; to advise you, promptly after it receives notice thereof, of the issuance by the Commission of any stop order or of any order preventing or suspending the use of the Preliminary Prospectus or other prospectus in respect of the Certificates, of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Act, of the suspension of the qualification of the Certificates for offering or sale in any

jurisdiction, of the initiation or threatening of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement or the Prospectus or for additional information; and, in the event of the issuance of any stop order or of any order preventing or suspending the use of the Preliminary Prospectus or other prospectus or suspending any such qualification, to promptly use its best efforts to obtain the withdrawal of such order; and in the event of any such issuance of a notice of objection, promptly to take such steps including, without limitation, amending the Registration Statement or filing a new registration statement, at its own expense, as may be necessary to permit offers and sales of the Certificates by the Underwriters (references herein to the Registration Statement shall include any such amendment or new registration statement). None of the foregoing obligations shall extend any later than the Prospectus Delivery Period.

          (c) If, at any time during such period after the date hereof and prior to the date on which all of the Certificates shall have been sold by the Underwriters, any event occurs as a result of which the Pricing Disclosure Package or the Prospectus would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend or supplement the Prospectus to comply with applicable law, the Company promptly will prepare and furnish, at its own expense, to the Underwriters, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in light of the circumstances when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

          (d) The Company will promptly take such actions as you may reasonably request to qualify the Certificates for offer and sale under the laws of such jurisdictions as you may reasonably request and will maintain such qualifications in effect so long as required for the distribution of such Certificates. The Company, however, shall not be obligated to qualify as a foreign corporation or file any general consent to service of process under the laws of any such jurisdiction or subject itself to taxation as doing business in any such jurisdiction.

          (e) Prior to 10:00 a.m., New York City time, on the New York Business Day next succeeding the date of this Agreement and from time to time, to furnish the Underwriters with written and electronic copies of the Prospectus in New York City in such quantities as you may reasonably request.

          (f) To make generally available to its securityholders as soon as practicable, but in any event not later than sixteen months after the effective date of the Registration Statement (as defined in Rule 158(c) under the Act), an earnings statement of the Company and its subsidiaries (which need not be audited) complying with Section 11(a) of the Act and the rules and regulations of the Commission thereunder (including, at the option of the Company, Rule 158).

          (g) To pay the required Commission filing fees relating to the Certificates within the time required by Rule 456(b)(1) under the Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Act.

          (h) To use the net proceeds received by it from the sale of the Series B Equipment Notes pursuant to this Agreement in the manner specified in the Preliminary Prospectus under the caption “Use of Proceeds”.

          (i) To cooperate with the Underwriters and use its reasonable efforts to permit the Certificates to be eligible for clearance and settlement through the facilities of DTC.

          (j) To issue Certificates, at Closing, that shall be rated at least BB by Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business (“S&P”) and Ba3 by Moody’s Investors Service, Inc. (“Moody’s”), respectively, and such ratings shall not be under surveillance or review with possible negative implications.

     Each Underwriter agrees that in the aggregate, the Certificates will be widely offered. Each Underwriter and each other member of the underwriting group that offers or sells Certificates agree that the Certificates offered by such Underwriter and such other member of the underwriting group will be primarily offered in the United States to United States persons. The term “United States person” shall have the meaning set forth in section 7701(a)(30) of the Internal Revenue Code of 1986, as amended.

     Each Underwriter, severally and not jointly, represents, warrants and covenants that (i) it is a QIB; (ii) it has solicited and will solicit offers for the Certificates only from, and it has offered and will offer and sell the Certificates only to, persons that it reasonably believes to be QIBs; and (iii) it has taken reasonable steps to ensure that such persons are aware that the Certificates may be resold only to QIBs and are aware of the transfer restrictions set forth in the Preliminary Prospectus under the heading “Description of the Certificates — Transfer Restrictions for Class B Certificates.”

          4. Conditions to the Obligations of the Underwriters. The obligations of the Underwriters to purchase and pay for the Certificates pursuant to this Agreement shall be subject in their discretion to the accuracy of and compliance with the representations and warranties of the Company contained herein as of the date hereof and the Closing Time, to the accuracy of the statements of the Company’s officers made in any certificates furnished pursuant to the provisions hereof, to the performance by the Company of its covenants and other obligations hereunder and to the following additional conditions:

          If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, other than by reason of any default by any Underwriter, such failure to fulfill a condition may be waived by you, or this Agreement may be terminated by you by notice

to the Company at any time at or prior to the Closing Time, and such termination shall be without liability of any party to any other party, except as provided in Sections 5, 7 and 10 hereof, which provisions shall remain in effect notwithstanding such termination.

          5. Payment of Expenses. The Company will pay or cause to be paid all expenses incident to the performance of the obligations of the Company under this Agreement, including (i) expenses relating to the preparation, printing, filing and distribution of the Pricing Disclosure Package, each Issuer Free Writing Prospectus listed on Schedule IV(a) hereto and the Prospectus and any amendments thereof or supplements thereto, (ii) expenses relating to the preparation, printing and distribution of any agreement among Underwriters, this Agreement, the Certificates, the Series B Equipment Notes, the Operative Documents, the Blue Sky Survey by the Underwriters’ counsel, (iii) expenses relating to the issuance and delivery of the Certificates to the Underwriters, (iv) the fees and disbursements of the Company’s counsel and accountants, (v) reasonable expenses of qualifying the Certificates under state securities laws in accordance with Section 3(d), including filing fees and reasonable fees and disbursements of counsel for the Underwriters in connection therewith and in connection with the Blue Sky Survey, (vi) the fees and expenses of the Trustee, the Subordination Agent, the Liquidity Provider, the Escrow Agent, the Paying Agent, the Loan Trustee and the Depositary, and the fees and disbursements of their respective counsel, (vii) any fees charged by rating agencies for rating the Certificates and (viii) certain fees and expenses of counsel for the Underwriters as heretofore agreed. The Company will also cause to be paid all expenses incident to the performance of its obligations under the Operative Documents and each of the other agreements and instruments referred to therein which are not otherwise specifically provided for in this Section. It is understood, however, that, except as provided in this Section, and Sections 7 and 11 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Certificates by them, and any advertising expenses connected with any offers they may make.

          6. Offering of Certificates. (a) (i) The Company represents and agrees that, other than the final term sheet prepared and filed pursuant to Section 3(b) hereof, without your prior consent, which consent shall not be unreasonably withheld or conditioned, it has not made and will not make any offer relating to the Certificates that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; (ii) each Underwriter represents and agrees that, without the prior consent of the Company, which consent shall not be unreasonably withheld or conditioned, other than one or more customary “Bloomberg Screens” to offer the Certificates or convey final pricing terms thereof that contain only information contained in the Pricing Disclosure Package, it has not made and will not make any offer relating to the Certificates that would constitute a free writing prospectus; and (iii) any such free writing prospectus the use of which has been consented to by the Company and the Underwriters is listed on Schedule IV(a) hereto (other than the final term sheet described in Section 1(c) hereof) .

          (b) The Company has complied and will comply in all material respects with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, and including, as applicable, timely filing with the Commission or retention where required and legending.

          (c) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Underwriters and, if requested by the Underwriters, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this undertaking shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by the Underwriters through you expressly for use therein.

          7. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, any Underwriter’s officers and directors, each affiliate of any Underwriter within the meaning of Rule 405 under the Act, as well as any affiliate’s officers and directors against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement 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, and (ii) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act (taken together with the Pricing Disclosure Package), 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 the light of the circumstances under which they were made, not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, (i) that the Company 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 in the Registration Statement, the Preliminary Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with, written information furnished to the Company by the Underwriters through you specifically for use in connection with the preparation thereof, it being understood and agreed that the only such information furnished by the Underwriters through you for inclusion in the Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus consists of the following information in the Prospectus: the third sentence in the fifth paragraph and the eleventh and twelfth paragraphs under the caption “Underwriting”. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

          (b) Each Underwriter severally agrees to indemnify and hold harmless the Company, each of its directors and officers and each person who controls the Company within

the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any loss, claim, damage, liability or action, but only with reference to written information furnished to the Company by the Underwriters through you specifically for inclusion in the Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus (taken together with the Pricing Disclosure Package) or in any amendment thereof or supplement thereto, it being understood and agreed that the only such information furnished by the Underwriters through you for inclusion in the Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus consists of the following information in the Prospectus: the third sentence in the fifth paragraph and the eleventh and twelfth paragraphs under the caption “Underwriting”. This indemnity agreement will be in addition to any liability which the Underwriters may otherwise have.

          (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 will not relieve it from any liability which it may have to any indemnified party otherwise than under Section 7(a) or (b) hereof, and then only to the extent that the indemnifying party is prejudiced thereby. 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 (i) 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), (ii) 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 (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 be only in respect of the counsel referred to in such clause (i) or (iii). 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. 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 (i) 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 (ii) 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 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 amount by which (i) the total price at which the Certificates resold by it in the initial placement of such Certificates were offered to investors exceeds (ii) the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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. For purposes of this Section 7, each person who controls any Underwriter within the meaning of either the Section 15 of the 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 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 Date 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 New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or materially limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (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.

          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 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.
