The Class AA Certificates will represent interests in the Company’s 2019-1AA Pass Through Trust (the “Class AA Trust”), the Class A Certificates will represent interests in the Company’s 2019-1A Pass Through Trust (the “Class A Trust”) and the Class B Certificates will represent interests in the Company’s 2019-1B Pass Through Trust (the “Class B Trust” and, together with the Class AA Trust and the Class A Trust, the “Trusts”), each established pursuant to the applicable Trust Agreement to fund the purchase of equipment notes (the “Equipment

Notes”) to be issued by the Company in connection with the financing of (a)(1) six Airbus A321-231S aircraft delivered new to the Company between December 2015 and May 2016; (2) three Boeing 737-800 aircraft delivered new to the Company in January 2016 and February 2016; (3) three Boeing 787-8 aircraft delivered new to the Company in May 2015 and February 2016; and (4) nine Embraer ERJ 175 LR aircraft delivered new to the Company between April 2015 and July 2019; and (b)(1) seven new Airbus A321-253NX aircraft currently scheduled for delivery to the Company during the period from June 2020 to September 2020; and (2) seven new Embraer ERJ 175 LR aircraft currently scheduled for delivery to the Company during the period from September 2019 to January 2020 (each such aircraft, an “Aircraft” and collectively, the “Aircraft”). Subject to the terms and conditions of the Note Purchase Agreement (as defined below) and the relevant participation agreements between the Company and WTC, as Trustee, Loan Trustee and Subordination Agent (each, a “Participation Agreement”), the Equipment Notes will be issued initially in three series under 35 separate Indenture and Security Agreements between WTC, as Loan Trustee (the “Loan Trustee”), and the Company (each, including any supplements thereto, an “Indenture” and, collectively, the “Indentures”).

The cash proceeds from the sale of the applicable Certificates by each Trust will be paid to Wilmington Trust, National Association (“WTNA”), acting as escrow agent (the “Escrow Agent”), under separate Escrow and Paying Agent Agreements, to be dated as of the Closing Date (as defined below), among the Escrow Agent, the Representatives, on behalf of the Underwriters, the Trustee and WTC, as paying agent (the “Paying Agent”), for the benefit of the holders of the Certificates issued by such Trust (each, an “Escrow Agreement” and, collectively, the “Escrow Agreements”). The Escrow Agent will deposit such cash proceeds (the “Deposits”) with Citibank, N.A. (the “Depositary”), in accordance with separate deposit agreements, to be dated as of the Closing Date, between the Escrow Agent and the Depositary relating to each Trust (each, a “Deposit Agreement” and, collectively, the “Deposit Agreements”), and will withdraw Deposits upon request to allow the Trustee of such Trust to purchase Equipment Notes in respect of the Aircraft from time to time pursuant to a Note Purchase Agreement, to be dated as of the Closing Date, among the Company, the Trustee, the Subordination Agent (as defined below), the Escrow Agent and the Paying Agent (the “Note Purchase Agreement”). With respect to each Certificate, the applicable 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 Depositary on behalf of such Escrow Agent and will pay to such holders through the applicable Paying Agent interest accrued on the Deposits and received by such Paying Agent pursuant to the applicable Deposit Agreement at a rate per annum equal to the interest rate applicable to such Certificate.

Certain amounts of interest payable on the applicable Certificates issued by each Trust will be entitled to the benefits of separate liquidity facilities. National Australia Bank (the “Liquidity Provider”), and the Subordination Agent will enter into separate revolving credit agreements with respect to each Trust (each a “Liquidity Facility” and, collectively, the “Liquidity Facilities”) to be dated as of the Closing Date, for the benefit of the holders of the Class AA Certificates, the Class A Certificates and the Class B Certificates, as applicable. The Liquidity Provider and the holders of the Certificates will be entitled to the benefits of an Intercreditor Agreement, to be dated as of the Closing Date (the “Intercreditor Agreement”), among the Trustee, the Liquidity Provider and WTC, as subordination agent and trustee thereunder (the “Subordination Agent”).

The supporting schedules included in the SEC Reports and incorporated by reference in the General Disclosure Package and to be incorporated by reference in the Final Prospectus present fairly in accordance with GAAP the information required to be stated therein.

The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

(ix)    Capitalization. All of the issued and outstanding capital stock of the Company has been duly authorized and validly issued, is fully paid and non-assessable and is owned by American Airlines Group Inc. (“AAG”) free and clear of any recorded liens, encumbrances, equities or claims.

The Equipment Notes will be (subject to the satisfaction of conditions precedent set forth in the Note Purchase Agreement and the Participation Agreements) duly executed and delivered by the Company at or prior to the applicable Closing Date (as defined in the applicable Participation Agreement). Each Operative Document to which the Company is, or is to be, a party, when duly executed and delivered by the Company, assuming that such document constitutes the legal, valid and binding obligation of each other party thereto, constitutes or will constitute, as the case may be, a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting enforcement of creditors’ rights generally and by general principles of equity.

The Equipment Notes, when duly executed and delivered by the Company and when duly authenticated by the Loan Trustee in accordance with the terms of the applicable Indenture, will be duly issued under such Indenture and will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms; and the holders thereof will be entitled to the benefits of such Indenture, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting enforcement of creditors’ rights generally and by general principles of equity.

(xiv)    Absence of Defaults and Conflicts. The Company is not in violation of its charter or by-laws or other constituting or organizational document or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any agreement or other instrument binding upon the Company or to which any of the property or assets of the Company is subject, except for such defaults that would not reasonably be expected to result in a Material Adverse Effect and that would not affect the validity of the Equipment Notes or the Certificates; and the execution and delivery by the Company of this Agreement, the Equipment Notes and the Operative Documents to which it is, or is to be, a party, the consummation by the Company of the transactions herein and therein contemplated, and the compliance by the Company with its obligations hereunder and thereunder and the terms hereof and thereof do not and will not, whether with or without the giving of notice or passage of time or both, (i) conflict with or constitute a breach of, or default or a Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, any agreement or other instrument binding upon the Company (except for such conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances that, singly or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect and that would not affect the validity of the Equipment Notes or the Certificates), (ii) result in a violation of the provisions of the certificate of incorporation or by-laws, as amended, or other constituting or organizational document of the Company, or (iii) result in a violation of any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, governmental instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its assets, properties or operations, except, in each case of this clause (iii), for such violations or defaults, that, singly or in the aggregate, would

8

not reasonably be expected to result in a Material Adverse Effect and that would not affect the validity of the Equipment Notes or the Certificates. As used herein, “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment prior to the stated maturity or date of mandatory redemption or repayment thereof of all or a portion of such indebtedness by the Company.

(xv)    Absence of Labor Dispute. Other than as described in the General Disclosure Package and the Final Prospectus, no labor dispute with the employees of the Company or any of its subsidiaries exists or, to the knowledge of the Company, is imminent, which the Company expects to have a Material Adverse Effect.

(xvii)    Absence of Proceedings. Other than as set forth in the General Disclosure Package and the Final Prospectus, there is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened, against the Company or any of its subsidiaries which, in the judgment of the Company, is likely to result in a Material Adverse Effect.

(xviii)    Absence of Further Requirements. No consent, approval, authorization, order or license of, or filing with or notice to, any government, governmental instrumentality, regulatory body or authority or court, domestic or foreign, is required for the valid authorization, issuance and delivery of the Certificates and the Equipment Notes, for the valid authorization, execution, delivery and performance by the Company of this Agreement, the Equipment Notes and the Operative Documents to which the Company is, or is to be, a party or for the consummation by the Company of the transactions contemplated by this Agreement, the Equipment Notes and the Operative Documents to which the Company is, or is to be, a party, except (A) such as has been already obtained or made, (B) such as are required under the Securities Act or the Securities Act Regulations or state securities or similar foreign laws in connection with the Registration Statement, (C) filings or recordings with respect to the Aircraft with the Federal Aviation Administration and registration with the International Registry and under the Uniform Commercial Code as in effect in Delaware and (D) as are disclosed in the General Disclosure Package and the Final Prospectus.

(xix)    Investment Company Act. The Company is not, nor upon the issuance and sale of the Certificates as contemplated by this Agreement and the application of the net proceeds therefrom as described in the General Disclosure Package and the Final Prospectus will be, an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended (the “1940 Act”), nor will any of the Trusts or the escrow arrangements relating to any Trust contemplated by the Escrow Agreements be required to register as an “investment company” as defined in the 1940 Act. In making the foregoing determination, the Trusts are relying upon the exemption from registration set forth in Rule 3a-7 under the 1940 Act, although additional exemptions or exclusions may be available to the Trusts.

(xx)    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.

(xxi)    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 properties.

10

(iii) regarding prevention or timely detection of unauthorized acquisition, use or disposition of its assets that could have a material effect on the financial statements, and (iv) that interactive data in eXtensible Business Reporting Language incorporated by reference in each of the General Disclosure Package and the Final Prospectus is prepared in accordance with the Commission’s rules and guidelines applicable thereto. The Company is not aware of any material weakness in its internal control over financial reporting that is reasonably likely to adversely affect its ability to record, process, summarize and report financial information.

(xxiii)    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.

(xxiv)    No Unlawful Payments. Neither of the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or other person associated with or acting on behalf of the Company or any of its subsidiaries has materially violated in the past five years or is in material violation of (1) laws relating to the use of any corporate funds for unlawful contributions, gifts, entertainment or other unlawful expenses relating to political activity, (2) laws relating to direct or indirect unlawful payments to any foreign or domestic government official or employee from corporate funds, (3) the Foreign Corrupt Practices Act of 1977, as amended, or the rules and regulations thereunder or (4) laws relating to bribes, rebates, payoffs, influence payments, kickbacks or other unlawful payments. The Company has implemented compliance programs for purposes of (a) informing the appropriate officers and employees of the Company and its subsidiaries of the Company’s policies to ensure compliance with the laws described under (1) through (4) above, and (b) 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.

(xxv)    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 any of the Underwriters for a brokerage commission, finder’s fee or other like payment in connection with this offering.

(xxvi)    Reporting Company. The Company is subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act.

(xxvii)    Well-Known Seasoned Issuer.

(a)    Immediately following the execution of this Agreement, the Company will (x) prepare the Final Prospectus that complies with the Securities Act and the Securities Act Regulations and which sets forth the aggregate face amount of the Certificates and their terms not otherwise specified in the base prospectus relating to all offerings of pass through certificates under the Registration Statement, the name of each Underwriter participating in the offering and the aggregate face amount of the Certificates that each severally has agreed to purchase, the name of each Underwriter, if any, acting as representative of the Underwriters in connection with the offering, the price at which the Certificates are to be purchased by the Underwriters from the Trustee, any initial public offering price, any selling concession and reallowance, and such other information as you and the Company deem appropriate in connection with the offering of the Certificates and (y) file all material required to be filed by the Company with the Commission pursuant to Rule 433(d) within the time required by such rule. 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 Certificates is required to be delivered under the Securities Act or the Securities Act Regulations, 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 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 Certificates is required to be delivered under the Securities Act or the Securities Act Regulations, 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 will promptly prepare and file with the Commission, subject to paragraph (d) of this

15

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 Certificates). Neither the Representatives’ 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 hereof.

(d)    At any time when a prospectus (or in lieu thereof, a notice referred to in Rule 173(a)) relating to the 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 the Representatives and their 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 EDGAR, 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 Underwriters 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 the Representatives 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 EDGAR, 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 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 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 such jurisdiction in which it is not otherwise so subject.

(g)    The Company shall 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 Certificates to be eligible for clearance and settlement through the facilities of DTC.

16

(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 Certificates is required to be delivered, will file promptly 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 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 the Representatives’ prior consent, offer, sell or enter into any agreement to sell any public debt securities registered under the Securities Act (other than the Certificates and any American Airlines Pass Through Certificates, Series 2019-1C, if any) 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.

(l)    If by the third anniversary (the “Renewal Deadline”) of the initial effective date of the Original Registration Statement, any of the Certificates remain unsold by the Underwriters, the Company will use its best efforts to file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Certificates, in a form satisfactory to the Representatives. If at the Renewal Deadline the Company is no longer eligible to file an automatic shelf registration statement, the Company will, if it has not already done so, use its best efforts to file a new shelf registration statement relating to the Certificates, in a form satisfactory to the Representatives and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Certificates to continue as contemplated in the expired registration statement relating to the Certificates. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

The Representatives agree 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.

This indemnity agreement will be in addition to any liability that the Company may otherwise have.

21

(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) hereof, 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 the information in the letter from the Representatives, dated as of the date of this Agreement, the form of which is attached here to as Exhibit F; provided, however, that the Underwriters 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 Underwriters (which consent shall not be unreasonably withheld), except to the extent that such consent is not required pursuant to Section 6(d) hereof.

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 such indemnifying party or parties 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) or (b), as applicable) of this Section 6 who are parties to such action in addition to one local counsel in each jurisdiction), (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) hereof and the proviso in Section 6(b) hereof 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 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 Certificates pursuant to this Agreement shall be deemed to be in the same proportion as the total

23

proceeds from the offering of the 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 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 Certificates underwritten by it and distributed to the public were offered 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 face amount of 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 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 Certificates specified to be purchased by each of them in Schedule I hereto bears to the aggregate face amount of Certificates to be purchased by all the remaining Underwriters) the Certificates which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate face amount of Certificates that the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate face amount of 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 Certificates,

24

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, Covenants, Indemnities and Agreements to Survive Delivery. All representations, warranties, covenants, 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, its affiliates, their respective directors and officers or any controlling person of either and shall survive delivery of any 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 Certificates or enforce contracts for the sale of the Certificates, or (iii) if trading in the securities of AAG or the Company 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, (a) if sent to the Representatives on behalf of the Underwriters, will be mailed or transmitted by any standard form of telecommunication to Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York 10013, Attention: Thomas Bliemel and Credit Suisse Securities (USA) LLC, 11 Madison Avenue, New York, New York 10010, Attention: IBCM Legal, and (b) if sent to the Company, will be mailed or transmitted by any standard form of telecommunication to the Company at P.O.

ICBC hereby represents, warrants and agrees that it shall offer, sell and otherwise distribute Certificates constituting its allotment solely outside the United States of America.

(b)    Notwithstanding anything to the contrary in this Agreement or in any other agreement, arrangement or understanding between the Company and ICBC, each of the Company and ICBC acknowledges that any liability of any EEA Financial Institution (as defined below) arising under this Agreement, to the extent such liability is unsecured, may be subject to the write-down and conversion powers of an EEA Resolution Authority (as defined below) and agrees and consents to, and acknowledges and agrees to be bound by:

12.    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, affiliates 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 Certificates from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

13.    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 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 Certificates or the process leading thereto (irrespective of whether the Underwriter has advised or is advising AAG 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 securities of the Company or its affiliates 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 or affiliates with respect thereto. Any review by any Underwriter of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of such Underwriter 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 each Underwriter 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.

27

Each of the parties to this Agreement agrees that a final action in any such suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other lawful manner.

(b)     Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, and agrees not to assert, by stay of motion, as a defense, or otherwise, in any legal action or proceeding brought hereunder in any of the above-named courts, that such action or proceeding is brought in an inconvenient forum, or that venue for the action or proceeding is improper.

(c)     Each party hereto 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.

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.    Recognition of the U.S. Special Resolutions Regimes.

(a)    In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime (as defined below), the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b)    In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate (as defined below) of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights (as defined below) under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.
