June 29, 2009

To the Underwriters named in Schedule I

Ladies and Gentlemen:

          American Airlines, Inc., a Delaware corporation (the “Company”), and wholly-owned subsidiary of AMR Corporation, a Delaware corporation (the “Parent”), proposes that U.S. Bank Trust National Association, a national banking association (“U.S. Bank”)(as successor to State Street Bank and Trust Company of Connecticut, National Association), acting not in its individual capacity but solely as successor pass through trustee (the “Trustee”) under the Pass Through Trust Agreement dated as of March 21, 2002 (the “Basic Agreement”), as supplemented for pass through certificates (the “Class A Certificates”) to be purchased hereunder by a Trust Supplement No. 2009-1A (the “Class A Trust Supplement”), between the Company and the Trustee (the Basic Agreement, as supplemented by the Class A Trust Supplement, being referred to herein as the “Class A Trust Agreement”), issue and sell to the underwriters named in Schedule I hereto (collectively, the “Underwriters”) its Class A Certificates in the aggregate amount and with the interest rate and final expected distribution date set forth on Schedule A hereto on the terms and conditions stated herein and in Schedule II.

          The Class A Certificates will represent interests in the Company’s 2009-1A Pass Through Trust (the “Class A Trust”) established pursuant to the Class A Trust Agreement to fund the purchase of equipment notes (the “Equipment Notes”) to be issued by the Company in connection with the financing of four Boeing 777-223ER aircraft owned by the Company (the “777-223ER Aircraft”) and sixteen Boeing 737-823 aircraft to be delivered to the Company on or October 31, 2010 (or later under certain circumstances)(the “737-823 Aircraft”). Subject to the terms and conditions of the Note Purchase Agreement (as defined below), in the case of the 737-823 Aircraft, and the relevant participation agreements between the Company and U.S. Bank, as Trustee, Loan Trustee and Subordination Agent (each, a “Participation Agreement”), the Equipment Notes will be issued under twenty separate Indenture and Security Agreements between U.S. Bank, as Loan Trustee (the “Loan Trustee”), and the Company (each, including any supplements thereto, an “Indenture” and, collectively, the “Indentures”).

          A portion of the cash proceeds from the sale of the Class A Certificates in the arrangement specified in the Final Prospectus (as defined below) will be applied at the Closing Time (as defined below) to purchase the Equipment Notes in respect of the 777-223ER Aircraft. The remaining portion of the cash proceeds from the sale of the Class A Certificates will be paid to U.S. Bank National Association (“U.S. Bank N.A.”), acting as escrow agent (the “Escrow Agent”), under an Escrow and Paying Agent Agreement among the Escrow Agent, the

Underwriters, the Trustee and U.S. Bank, as paying agent (the “Paying Agent”), for the benefit of the holders of the Class A Certificates (the “Escrow Agreement”). The Escrow Agent will deposit such cash proceeds (the “Deposits”) with The Bank of New York Mellon (the “Depositary”), in accordance with a deposit agreement relating to the Class A Trust (the “Deposit Agreement”), and will withdraw Deposits upon request to allow the Trustee of the Class A Trust to purchase Equipment Notes in respect of the 737-823 Aircraft from time to time pursuant to a Note Purchase Agreement to be dated as of the Closing Time (as defined below) among the Company, the Trustee and U.S. Bank, as the Paying Agent and the Escrow Agent (the “Note Purchase Agreement”) . With respect to each Class A Certificate, the Escrow Agent will issue a receipt to be attached to such Class A Certificate (each an “Escrow Receipt”) representing a fractional undivided interest of the holder of such Class A 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 Class A Certificate.

          Certain amounts of interest payable on the Class A Certificates issued by the Class A Trust will be entitled to the benefits of a liquidity facility. Natixis S.A., acting via its New York Branch (the “Liquidity Provider”) will enter into a revolving credit agreement with respect to the Class A Trust (the “Liquidity Facility”), to be dated as of the Closing Time, for the benefit of the holders of the Class A Certificates. The Liquidity Provider and the holders of the Class A Certificates will be entitled to the benefits of an Intercreditor Agreement to be dated as of the Closing Time (the “Intercreditor Agreement”) among the Trustee, U.S. Bank, as subordination agent and trustee thereunder (the “Subordination Agent”), and the Liquidity Provider.

     (s) Environmental Laws. There has been no storage, disposal, generation, manufacture, refinement, transportation, handling or treatment of toxic wastes, medical wastes, hazardous wastes or hazardous substances by the Company (or, to the knowledge of the Company, any of its predecessors in interest), or at, upon or from any of the property now or previously owned or leased by the Company in violation of, and the Company has no liability under, any applicable law, ordinance, rule, regulation, order, judgment, decree or permit or which would require remedial action under any applicable law, ordinance, rule, regulation, order, judgment, decree or permit applicable to the Company, except for any violation, liability or remedial action which would not have, or could not be reasonably likely to have, singularly or in the aggregate with all such violations, liabilities and remedial actions, a Material Adverse Effect; there has been no spill, discharge, leak, emission, injection, escape, dumping or release of any kind by the Company onto such property or into the environment surrounding such property of any toxic wastes, medical wastes, solid wastes, hazardous wastes or hazardous substances due to or caused by the Company or with respect to which the Company has knowledge, except for any such spill, discharge, leak, emission, injection, escape, dumping or release which would not have or would not be reasonably likely to have, singularly or in the aggregate with all such spills, discharges, leaks, emissions, injections, escapes, dumpings and releases, a Material Adverse Effect. The terms “hazardous wastes,” “toxic wastes,” “hazardous substances” and “medical wastes” shall have the meanings specified in any applicable local, state, federal and foreign laws or regulations with respect to environmental protection or human health. In the ordinary course of its business, the Company conducts a periodic review of the effect of any and all applicable foreign, federal, state and local laws and regulations relating to the protection of human health and safety, the environment, and hazardous and toxic substances and wastes, pollutants and contaminants (“Environmental Laws”) on the business, operations and properties of the Company, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities have not had and would

not, singularly or in the aggregate, reasonably be expected to have a Material Adverse Effect.

     (u) Insurance. The Company carries, or is covered by, insurance in such amounts and covering such risks as is adequate for the conduct of its business and the value of its respective properties.

     (v) Taxes. The Company has filed all federal, state and local income and franchise tax returns required to be filed through the date hereof, except for such exceptions as would not individually or collectively have a Material Adverse Effect, and has paid all taxes due thereon, except such as are being contested in good faith by appropriate proceedings, and no tax deficiency has been determined adversely to the Company which has had, nor does the Company have any knowledge of any tax deficiency which, if determined adversely to the Company, might have, a Material Adverse Effect.

     (w) Internal Controls. The Company (A) makes and keeps accurate books and records that, in reasonable detail, accurately and fairly reflect the transactions and disposition of the assets of the Company, and (B) maintains internal accounting controls which provide reasonable assurance that (i) transactions are executed in accordance with management’s authorization, (ii) transactions are recorded as necessary to permit preparation of its financial statements in conformity with generally accepted accounting principles and to maintain accountability for its assets, (iii) access to its assets is permitted only in accordance with management’s authorization and (iv) the recorded accountability for its assets is compared with existing assets at reasonable intervals. The Company maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) that has been designed by the Company’s principal executive officer and principal financial officer, or under their supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company is not aware of any material weaknesses in its internal control over financial reporting which are reasonably likely to adversely

affect the Company’s ability to record, process, summarize and report financial information. Since the date of the latest audited financial statements included in the General Disclosure Package and the Final Prospectus, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

     (x) Disclosure Controls and Procedures. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) of the Exchange Act) that have been designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s principal executive officer and principal financial officer by others within those entities; such disclosure controls and procedures are effective.

     (y) No Unlawful Payments. The Company has implemented compliance programs for purposes of (i) informing the appropriate officers and employees of the Company and its subsidiaries of (A) the Company’s policies against (1) the use of corporate funds for unlawful contributions, gifts, entertainment or other unlawful expenses relating to political activity, (2) direct or indirect unlawful payments to any foreign or domestic government official or employee from corporate funds, (3) violations of the Foreign Corrupt Practices Act of 1977, as amended, and (4) making any bribes, rebates, payoffs, influence payments kickbacks or other unlawful payments and (ii) requiring such officers and employees to report to the Company any knowledge they may have of violations of the Company’s policies referred to above and no such reports have been made.

     (z) No Brokerage Commission; Finder’s Fee. To the best of the Company’s knowledge after due inquiry, there are no contracts, agreements or understandings between the Company and any person that would give rise to a valid claim against the Company or the Underwriters for a brokerage commission, finder’s fee or other like payment in connection with this offering.

The Company will promptly transmit copies of the Final Prospectus to the Commission for filing pursuant to Rule 424 and will furnish to the Underwriters as many copies of the Final Prospectus as you shall reasonably request.

     (b) During the period when a prospectus (or in lieu, thereof, a notice referred to in Rule 173(a) under the Securities Act (“Rule 173(a)”) relating to the Class A Certificates

is required to be delivered under the Securities Act, the Company will promptly advise you of (i) the effectiveness of any amendment to the Registration Statement, (ii) the transmittal to the Commission for filing of any supplement to the Final Prospectus or any document that would as a result thereof be incorporated by reference in the Final Prospectus, (iii) any request by the Commission for any amendment of the Registration Statement or any amendment or supplement to the Final Prospectus or for any additional information relating thereto or to any document incorporated by reference therein, (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose, and (v) the receipt by the Company of any notification with respect to the suspension of the qualification of the Class A Certificates for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or suspension and, if issued, to obtain as soon as possible the withdrawal thereof.

     (c) If, at any time when a prospectus (or in lieu thereof, a notice referred to in Rule 173(a)) relating to the Class A Certificates is required to be delivered under the Securities Act, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend or supplement the Final Prospectus to comply with the Securities Act or the Securities Act Regulations, the Company promptly will prepare and file with the Commission, subject to paragraph (d) of this Section 3, an amendment or supplement which will correct such statement or omission or an amendment or supplement which will effect such compliance and the Company will use its reasonable efforts to have any such amendment to the Registration Statement or new registration statement declared effective as soon as practicable (if it is not an automatic shelf registration statement with respect to the Class A Certificates). Neither your consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 4.

     (d) At any time when a prospectus (or in lieu thereof, a notice referred to in Rule 173(a)) relating to the Class A Certificates is required to be delivered under the Securities Act or the Securities Act Regulations, the Company will give you notice of its intention to file any amendment to the Registration Statement or any amendment or supplement to the Final Prospectus, whether pursuant to the Exchange Act, the Securities Act or otherwise, will furnish you with copies of any such amendment or supplement or other documents proposed to be filed within a reasonable time in advance of filing, and will not file any such amendment or supplement or other documents in a form to which you shall reasonably object.

     (e) The Company has furnished or will furnish, if requested, to you and your counsel, without charge, conformed copies of the Original Registration Statement and of all amendments thereto, whether filed before or after such Registration Statement originally became effective (including exhibits thereto and the documents incorporated therein by reference) and the copies of the Original Registration Statement and each

amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T. So long as delivery of a Final Prospectus (or in lieu thereof, a notice referred to in Rule 173(a)) by the Underwriter may be required by the Securities Act, the Company will furnish as many copies of any Statutory Prospectus, the Final Prospectus and any amendments thereof and supplements thereto as you may reasonably request and the Final Prospectus and any amendments or supplements thereto furnished to each Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T or required under Rule 424(e).

     (f) The Company shall use its reasonable efforts, in cooperation with the Underwriters, to qualify the Class A Certificates for offering and sale under the applicable securities laws of such states in the United States as the Underwriters may reasonably designate and will maintain such qualifications in effect so long as required in connection with the distribution of the Class A Certificates; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

     (g) The Company intends to use the proceeds received by it from the sale of the Equipment Notes in the manner to be indicated in the Final Prospectus under “Use of Proceeds.”

     (h) The Company shall cooperate with the Underwriters and use its reasonable efforts to permit the Class A Certificates to be eligible for clearance and settlement through the facilities of DTC.

     (i) The Company, during the period when a Final Prospectus (or in lieu thereof, the notice referred to in Rule 173(a)) relating to the Class A Certificates is required to be delivered, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the Exchange Act Regulations.

     (j) The Company represents and agrees that, unless it obtains the prior consent of each Underwriter, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Class A Certificates that would constitute an “issuer free writing prospectus,” as defined in Rule 433 or that would otherwise constitute a “free writing prospectus” as defined in Rule 405. Any such free writing prospectus consented to by the Company and the Underwriters is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 as applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

     (k) Between the date of this Agreement and the Closing Time, the Company will not, without your prior consent, offer, sell or enter into any agreement to sell any public debt securities registered under the Securities Act (other than the Class A Certificates) or any debt securities which may be sold in a transaction exempt from the registration requirements of the Securities Act in reliance on Rule 144A under the Securities Act and which are marketed through the use of a disclosure document containing substantially the same information as a prospectus for similar debt securities registered under the Securities Act.

     The Representatives agree that in the aggregative, the Pass Through Certificates will be widely offered. Each Underwriter and each other member of the underwriting group that offers or sells Pass Through Certificates agree that the Pass Through 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.

the statements therein not misleading, or (2) arise out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the General Disclosure Package or in the Final Prospectus or in any amendment thereof or supplement thereto or in any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and, in each case, agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that (i) 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 any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon, and in conformity with, written information relating to any Underwriter furnished to the Company by or on behalf of such Underwriter specifically for use in the Registration Statement (or any amendment thereto) or any Issuer Free Writing Prospectus or the General Disclosure Package or the Final Prospectus (or any amendment or supplement thereto) or made in those parts of the Registration Statement constituting a Statement of Eligibility under the TIA of a trustee on Form T-1, and (ii) the Company shall not be liable for any loss, liability or expense of any settlement or compromise of or consent to entry of judgment with respect to, any pending or threatened litigation or any pending or threatened governmental agency investigation or proceeding if such settlement or compromise of or consent to entry of judgment with respect thereto is effected without the prior written consent of the Company, except to the extent that such consent is not required pursuant to Section 6(d) hereof. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

          (b) Each Underwriter severally agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement, and each person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all losses, claims, damages, liabilities and expenses described in the indemnity contained in Section 6(a), but only with respect to untrue statements or alleged untrue statements or omissions or alleged omissions made in the Registration Statement (or any amendment thereto), any Permitted Free Writing Prospectus, the General Disclosure Package, or the Final Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter specifically for use in the Registration Statement (or any amendment thereto), the General Disclosure Package, any Permitted Free Writing Prospectus or the Final Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information provided by any Underwriter consists of (i) the statements with respect to the offering of the Class A Certificates by the Underwriters in the third sentence of the second full paragraph under the caption “Underwriting” in the Statutory Prospectus and the Final Prospectus, (ii) the statements with respect to the offering of the Class A Certificates by the Underwriters set forth in the fourth full paragraph under the caption “Underwriting” in the Statutory Prospectus and the Final Prospectus, (iii) the statements with respect to marketing activities by the Underwriters for the Class A Certificates in the third and fourth sentences of the fifth full paragraph under the caption “Underwriting” in the Statutory Prospectus and the Final Prospectus, and (iv) the statements with respect to stabilization and over-allotment of the Class A Certificates by the Underwriters (with respect to themselves only) in the ninth and tenth full paragraphs under the caption

“Underwriting” in the Statutory Prospectus and the Final Prospectus. This indemnity agreement will be in addition to any liability that any Underwriter may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section 6 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 6, notify the indemnifying party or parties in writing of the commencement thereof; but the omission so to notify the indemnifying party or parties will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 6. In case any such action is brought against any indemnified party and it notifies the indemnifying party or parties of the commencement thereof, the indemnifying party or parties will be entitled to participate therein, 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 satisfactory to such indemnified party; provided, however, that if, in the reasonable judgment of such indemnified party, a conflict of interest exists where it is advisable for such indemnified party to be represented by separate counsel, the indemnified party shall have the right to employ separate counsel in any such action, in which event the fees and expenses of such separate counsel shall be borne by the indemnifying party or parties. Upon receipt of notice from the indemnifying party or parties to such indemnified party of the election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party or parties will not be liable to such indemnified party under this Section 6 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 or parties shall not be liable for the expenses of more than one such separate counsel representing the indemnified parties under subparagraph (a) of this Section 6 who are parties to such action), (ii) the indemnifying party or parties 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 or parties have authorized the employment of counsel for the indemnified party at the expense of the indemnifying party or parties; 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). It is understood that all such fees and expenses of counsel for the indemnified party for which the indemnifying party is liable shall be reimbursed as they are incurred. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement or compromise of, or consent to entry of judgment with respect to, 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 or compromise of, or consent to entry of judgment with respect to, includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

          (d) If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel payable pursuant to this Section 6, such indemnifying party agrees that it shall be liable for any settlement, compromise or consent to entry of judgment of the nature contemplated by clause (ii) of the

proviso in Section 6(a) effected without its written consent if (i) such settlement, compromise or consent to entry of judgment is entered into more than 45 days after receipt by such indemnifying party of the aforesaid notice of request, (ii) such indemnifying party shall have received notice of the terms of such settlement, compromise or consent to entry of judgment at least 30 days prior to such settlement being entered into, and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement, compromise or consent to entry of judgment.

          (e) If the indemnification provided for in paragraph (a) or (b) of this Section 6 is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, (i) 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 hand from the offering of the Class A Certificates pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, 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 Class A Certificates pursuant to this Agreement shall be deemed to be in the same proportion as the total proceeds from the offering of the Class A Certificates pursuant to this Agreement (net of underwriting discounts and commissions paid to the Underwriters but before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters in each case as set forth on the cover of the Final Prospectus, bears to the aggregate initial public offering price of the Class A Certificates as set forth on such cover. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters 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 Section 6 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 6. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 6 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any such action or claim. Notwithstanding the provisions of this Section 6, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Class A Certificates underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each person, if any, who controls any Underwriter within the meaning of Section 15 of

the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 6 are several in proportion to the principal amount of Class A Certificates set forth opposite their respective names in Schedule I hereto and not joint.

          7. Default. If any one or more Underwriters shall fail at the Closing Time to purchase and pay for any of the Class A Certificates agreed to be purchased by such Underwriter or Underwriters pursuant to this Agreement and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the aggregate face amount of Class A Certificates specified to be purchased by them in Schedule I bears to the aggregate face amount of Class A Certificates to be purchased by all the remaining Underwriters) the Class A Certificates which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate face amount of Class A Certificates that the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate face amount of Class A Certificates to be purchased pursuant to this Agreement, the remaining Underwriters shall have the right, but not the obligation within 24 hours thereafter, to make arrangements to purchase all, but not less than all, of such Class A Certificates, and if such nondefaulting Underwriters do not complete such arrangements within such 24 hour period, then this Agreement will terminate without liability to any nondefaulting Underwriters or the Company. In the event of any such termination, the provisions of Sections 5, 6 and 8 hereof shall remain in effect. In the event of a default by any Underwriter as set forth in this Section 7 that does not result in a termination of this Agreement, the Closing Time shall be postponed for such period, not exceeding seven days, as the nondefaulting Underwriters or the Company shall determine in order that the required changes in the General Disclosure Package and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and to any nondefaulting Underwriters for damages occasioned by its default hereunder.

          8. Representations, Warranties, Indemnities and Agreements to Survive Delivery. All representations, warranties, indemnities and agreements contained in this Agreement, or contained in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Company or any Underwriter or any controlling person of either and shall survive delivery of any Class A Certificates to the Underwriters.

          9. Termination. This Agreement may be terminated immediately upon notice from you to the Company at any time at or prior to the Closing Time (i) if there has been, since the respective dates as of which information is given in the Registration Statement and the Final Prospectus (exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), any material adverse change in the condition, financial or otherwise, of the Company and its subsidiaries considered as one enterprise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or

not arising in the ordinary course of business, or (ii) if there has occurred any outbreak or escalation of hostilities or any material adverse change in the financial markets in the United States or in the international financial markets or any other calamity or crisis the effect of any of which on the financial markets is such as to make it, in your judgment, impracticable to market the Class A Certificates or enforce contracts for the sale of the Class A Certificates, or (iii) if trading in the securities of the Parent has been suspended by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange has been suspended, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by said exchange or by order of the Commission or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities. In the event of any such termination, the provisions of Sections 5, 6 and 8 hereof shall remain in effect.

          10. Notices. All notices and other communications hereunder shall be in writing and effective only upon receipt, and, if sent to the Underwriters, will be mailed or transmitted by any standard form of telecommunication to the Underwriters as set forth in Schedule I or, if sent to the Company, will be mailed or transmitted by any standard form of telecommunication to it at ▇.▇. ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇/▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, facsimile no. (▇▇▇) ▇▇▇-▇▇▇▇, attention of the Treasurer.

          11. Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriters and the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the parties hereto and their respective successors and the controlling persons and officers and directors referred to in Section 6 hereof and their successors, heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties and their respective successors and said controlling persons and officers and directors and their successors, heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Class A Certificates from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

          12. No Fiduciary Duty. The Company acknowledges and agrees that each Underwriter is acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Class A Certificates contemplated hereby (including in connection with determining the terms of such offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any of its subsidiaries. Additionally, no Underwriter is advising the Company or any of its subsidiaries as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction with respect to the offering of the Class A Certificates or the process leading thereto (irrespective of whether the Underwriter has advised or is advising the Parent or the Company on other matters). Each Underwriter advises that it and its affiliates are engaged in a broad range of securities and financial services and that it and its affiliates may enter into contractual relationships with purchasers or potential purchasers of the Parent’s or the Company’s securities and that some of these services or relationships may involve interests that differ from those of the Company and need not be disclosed to the Company, unless otherwise required by law. The Company has consulted with its own advisors concerning such matters and

shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and no Underwriter shall have any responsibility or liability to the Company or any of its subsidiaries with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company. The Company 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 agrees that no Underwriter shall have any liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim.

          13. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

          14. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

          15. Counterparts. This Agreement may be executed in one or more counterparts and when a counterpart has been executed by each party hereto all such counterparts taken together shall constitute one and the same agreement.
