If, at any time after the public offering of the Securities, the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales of the Securities by an Underwriter or a dealer, any event shall occur as a result of which it is necessary to amend or supplement the Prospectus so that the statements therein will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, contain a material misstatement or omission, or if it is necessary to amend the Registration Statement or amend or supplement the Prospectus to comply with law, the Company shall prepare and furnish at its expense to the Underwriters and to the dealers (whose names and addresses the Representative will furnish to the Company) to which Securities may have been sold by the Representative on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, contain a material misstatement or omission, or amendments or supplements to the Registration Statement or the Prospectus so that the Registration Statement or the Prospectus, as so amended or supplemented, will comply with law and cause such amendments or supplements to be filed promptly with the Commission.

(b)    During the period mentioned in paragraph (a) above, the Company shall notify each Underwriter immediately of (i) the effectiveness of any amendment to the Registration Statement, (ii) the transmittal to the Commission for filing of any supplement to the Prospectus or any document that would as a result thereof be incorporated by reference in the Prospectus, (iii) the receipt of any comments from the Commission with respect to the Registration Statement or the Prospectus, (iv) any request by the Commission to the Company for any amendment to the Registration Statement or any supplement to the Prospectus or for additional information relating thereto or to any document incorporated by reference in the Prospectus and (v) receipt by the Company of any notice of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or the institution or threatening of any proceeding for any of such purposes; and the Company agrees to use every reasonable effort to prevent the issuance of any such stop order and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment and the Company shall endeavor (subject to the proviso to Section 4(g)), in cooperation with the Underwriters, to prevent the issuance of any such stop order suspending such qualification and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment.

(c)    During the period mentioned in paragraph (a) above, the Company will furnish to each Underwriter as many conformed copies of the Registration Statement (as originally filed), the Time of Sale Prospectus, the Prospectus, and all amendments and supplements to such documents (excluding all exhibits and documents filed therewith or incorporated by reference therein) and as many conformed copies of all consents and certificates of experts, in each case as soon as available and in such quantities as each Underwriter reasonably requests.

13

(d)    Promptly following the execution of this Agreement, the Company will prepare a Prospectus that complies with the Securities Act and that sets forth the principal amount of the Securities and their terms not otherwise specified in the preliminary prospectus or the Basic Prospectus included in the Registration Statement, the name of each Underwriter and the principal amount of the Securities 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 Securities are to be purchased by the Underwriters from the Company, any initial public offering price, any selling concession and reallowance and any delayed delivery arrangements, and such other information as the Representative and the Company deem appropriate in connection with the offering of the Securities. The Company will timely transmit copies of the Prospectus to the Commission for filing pursuant to Rule 424 under the Securities Act.

(e)    The Company shall furnish to each Underwriter a copy of each free writing prospectus relating to the offering of the Securities prepared by or on behalf of, used by, or referred to by the Company and shall not use or refer to any proposed free writing prospectus to which the Representative reasonably objects.

(f)    If the Time of Sale Prospectus or any “issuer free writing prospectus” is being used to solicit offers to buy the Securities at a time when a Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus or any “issuer free writing prospectus” in order to make the statements therein, in the light of the circumstances when it is delivered to a prospective purchaser, not misleading in any material respect, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus or any “issuer free writing prospectus” conflicts with the information contained in the Registration Statement then on file, or if it is necessary to amend or supplement the Time of Sale Prospectus or any “issuer free writing prospectus” to comply with applicable law, the Company shall forthwith prepare, file promptly with the Commission and furnish, at the Company’s expense, to the Underwriters and to the dealers (whose names and addresses the Representative will furnish to the Company) to which Securities may have been sold by the Representative on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Time of Sale Prospectus or such “issuer free writing prospectus” so that the statements in the Time of Sale Prospectus or such “issuer free writing prospectus”, as so amended or supplemented, will not, in the light of the circumstances when it is delivered to a prospective purchaser, be misleading in any material respect or so that the Time of Sale Prospectus or such “issuer free writing prospectus”, as so amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus or such “issuer free writing prospectus”, as amended or supplemented, will comply with applicable law.

(g)    The Company shall, in cooperation with the Underwriters, endeavor to arrange for the qualification of the Securities for offer and sale under the applicable securities or “blue sky” laws of such jurisdictions in the United States as the Representative reasonably designates and will endeavor to maintain such qualifications in effect so long as required for the distribution of such Securities; provided that neither the Company nor the Guarantor shall be required to (i) qualify as a foreign corporation or as a dealer in securities, (ii) file a general consent to service of process or (iii) subject itself to taxation in any such jurisdiction.

14

(h)    During the period of ten years after the Closing Date, the Company will promptly furnish to each Underwriter, upon request, copies of all Annual Reports on Form 10-K and any definitive proxy statement of the Company (including any successor by merger of the Company) filed with the Commission; provided that (a) filing such documents with the Commission or (b) providing a website address at which such Annual Reports and any such definitive proxy statements may be accessed will satisfy this clause (h).

(i)    If the third anniversary of the initial effective date of the Registration Statement occurs before all the Securities have been sold by the Underwriters, then prior to the third anniversary the Company and the Guarantor shall file a new shelf registration statement and take any other action necessary to permit the public offering of the Securities to continue without interruption, in which case references herein to the Registration Statement shall include the new registration statement as it shall become effective.

(j)    Between the date of this Agreement and the date that is 30 days after the Closing Date, the Company and the Guarantor shall not, without the prior written consent of the Representative, offer, sell or enter into any agreement to sell (as public debt securities registered under the Securities Act or as debt securities which may be resold in a transaction exempt from the registration requirements of the Securities Act in reliance on Rule 144A thereunder 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) any debt securities issued or guaranteed by the Company or the Guarantor and having the term of more than one year (other than (i) the Securities, (ii) any equipment notes, pass through certificates, equipment trust certificates or equipment purchase certificates secured by aircraft owned by the Company (or rights relating thereto), (iii) any notes convertible into shares of common stock of the Company, and (iv) any municipal bonds relating to financing or refinancing any airport facilities).

(k)    The Company shall prepare a final term sheet relating to the offering of the Securities, containing only information that describes the final terms of the Securities or the offering in a form consented to by the Representative and shall file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Securities Act following the date the final terms have been established for the offering of the Securities.

(l)    Neither the Company nor the Guarantor will take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

5.    Certain Covenants of the Underwriters. Each Underwriter represents, warrants and covenants that it has not made and will not make any offer relating to the Securities that would constitute an issuer free writing prospectus; provided that this Section 5 shall not prevent any Underwriter from transmitting or otherwise making use of one or more customary “Bloomberg Screens” to offer the Securities or convey final pricing terms thereof that contain only information contained in the Time of Sale Prospectus.

15

6.    Indemnification and Contribution. (a) Each of the Company and the Guarantor agrees jointly and severally to indemnify and hold harmless each Underwriter, its directors and officers and the affiliates of each Underwriter who have, or who are alleged to have, participated in the distribution of the Securities as underwriters, and each Person, if any, who controls such Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any “issuer free writing prospectus” as defined in Rule 433(h) under the Securities Act, any “issuer information” that the Company or the Guarantor has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or the Prospectus, or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any of the aforementioned losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished to the Company in writing by any Underwriter through the Representative expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus, or any amendment or supplement thereto (the “Underwriter Information”).

(b)    Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantor, their respective directors, each of their respective officers who signed the Registration Statement and each person, if any, who controls the Company or the Guarantor within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company and the Guarantor to such Underwriter but only with reference to the Underwriter Information provided by such Underwriter.

(c)    In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either paragraph (a) or (b) above, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such paragraph. The indemnifying party, upon request of the indemnified party, shall, and the indemnifying party may elect to, retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and the indemnifying party shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include

16

both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, or (iii) the indemnifying party shall have failed to retain counsel as required by the prior sentence to represent the indemnified party within a reasonable amount of time. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representative in the case of parties indemnified pursuant to paragraph (a) above and by the Company in the case of parties indemnified pursuant to paragraph (b) above. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested in writing an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph (c), the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement, unless such fees and expenses are being disputed in good faith. The indemnifying party at any time may, subject to the last sentence of this paragraph (c), settle or compromise any proceeding described in this paragraph (c), at the expense of the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d)    To the extent the indemnification provided for in paragraph (a) or (b) of this Section 6 is required to be made but is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the applicable indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities or (ii) if the allocation provided by clause (i) above 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 and the Guarantor, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, on the other hand, in connection with the offering of such Securities shall be deemed to be in the

17

same respective proportions as the proceeds from the offering of such Securities received by the Company (before deducting expenses), less total underwriting discounts and commissions received by the Underwriters, and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of such Securities. The relative fault of the Company and the Guarantor, on the one hand, and of the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantor or information supplied by any Underwriter, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 6 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

(e)    The Company, the Guarantor and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, no Underwriter shall be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Underwriter with respect to the Securities underwritten by it and distributed to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f)     The indemnity and contribution provisions contained in this Section 6 and the representations and warranties of the Company and the Guarantor contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, the Guarantor, each of their respective officers or directors or any person controlling the Company or the Guarantor, and (iii) acceptance of and payment for any of the Securities. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

7.    Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Securities hereunder and the aggregate principal amount of the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Securities, the Representative may make arrangements satisfactory to the Company for the purchase of such Securities by other persons,

18

including any of the non-defaulting Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of the Securities with respect to which such default or defaults occurs exceeds 10% of the total principal amount of the Securities and arrangements satisfactory to the Representative and the Company for purchase of such Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Guarantor, except as provided in Section 6. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

8.    Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantor or their respective officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any termination of this Agreement, any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the Guarantor or any of their respective representatives, officers or directors or any controlling person and will survive delivery of and payment for the Securities. If for any reason the purchase of the Securities by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 10 hereof and the respective obligations of the Company, the Guarantor and the Underwriters pursuant to Section 6 hereof shall remain in effect. If the purchase of the Securities by the Underwriters is not consummated for any reason other than solely because of the occurrence of the termination of the Agreement pursuant to Section 7 or 9 hereof, the Company and the Guarantor will jointly and severally reimburse the Underwriters for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by the Underwriters in connection with the offering of such Securities and comply with its obligations under Sections 6 and 10 hereof.

9.    Termination. This Agreement shall be subject to termination by notice given by the Representative to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been materially suspended or materially limited on or by, as the case may be, either of the New York Stock Exchange or the NASDAQ Global Market, (ii) trading of any securities of the Company or the Guarantor shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, (iv) there shall have occurred any attack on, or outbreak or escalation of hostilities or act of terrorism involving, the United States, or any change in financial markets or any calamity or crisis that, in each case, in the judgment of the Representative, is material and adverse or (v) there shall have occurred any major disruption of settlements of securities or clearance services in the United States that would materially impair settlement and clearance with respect to the Securities and (b) in the case of any of the events specified in clauses (a)(i) through (v), such event singly or together with any other such event makes it, in the judgment of the Representative, impracticable to market the Securities on the terms and in the manner contemplated in the Time of Sale Prospectus.

19

10.    Payment of Expenses. As among the Company, the Guarantor and the Underwriters, the Company or the Guarantor shall pay all expenses incidental to the performance of the Company’s and the Guarantor’s obligations under this Agreement, including the following:

(i)    expenses incurred in connection with (A) qualifying the Securities for offer and sale under the applicable securities or “blue sky” laws of such jurisdictions in the United States as the Representative reasonably designates (including filing fees and fees and disbursements of counsel for the Underwriters in connection therewith), (B) endeavoring to maintain such qualifications in effect so long as required for the distribution of such Securities, (C) the review (if any) of the offering of the Securities by FINRA, (D) the determination of the eligibility of the Securities for investment under the laws of such jurisdictions as the Underwriters may designate and (E) the preparation and distribution of any blue sky or legal investment memorandum by Milbank LLP, Underwriters’ counsel;

(iii)    the expenses incurred in connection with the preparation, printing and filing of the Registration Statement (including financial statements and exhibits), as originally filed and as amended, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any issuer free writing prospectus and any amendments and supplements to any of the foregoing, including the filing fees payable to the Commission relating to the Securities (within the time period required by Rule 456(b)(1), if applicable), and the cost of furnishing copies thereof to the Underwriters and dealers;

(iv)    expenses incurred in connection with the preparation, printing and distribution of this Agreement, the Securities and the Supplemental Indenture;

(v)    expenses incurred in connection with the delivery of the Securities to the Underwriters;

(ix)    all other reasonable out-of-pocket expenses incurred by the Underwriters in connection with the transactions contemplated by this Agreement (excluding the fees and disbursements of Milbank LLP as counsel for the Underwriters); and

15.    Recognition of the U.S. Special Resolution 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.

21

(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.

(a)    Each party hereto hereby irrevocably agrees, accepts and submits itself to the exclusive jurisdiction of the courts of the State of New York in the City and County of New York and of the United States for the Southern District of New York, in connection with any legal action, suit or proceeding with respect to any matter relating to or arising out of or in connection with this Agreement.

19.    No Fiduciary Duty.

The Company and the Guarantor acknowledge that the Underwriters and their affiliates may provide financing or other services to parties whose interests may conflict with those of the Company and the Guarantor and may enter into transactions in the Company’s common stock or other securities, including the Securities, for their accounts and their customers’ accounts. The Company and the Guarantor acknowledge that they are not relying on the advice of the Underwriters for tax, legal or accounting matters, that they are seeking and will rely on the advice of their own professionals and advisors for such matters and that they will make an independent analysis and decision regarding the offering of the Securities based upon such advice.

The Company and the Guarantor acknowledge that the Underwriters are not in the business of providing tax advice and that they have received tax advice from their own tax advisors with appropriate expertise to assess any tax risks. Each of the Company and the Guarantor waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.
