Ladies and Gentlemen:

US Airways, Inc., a Delaware corporation (the “Company”), proposes that Wilmington Trust Company, as trustee under each of the Original Trusts (as defined below) (the “Trustee”), issue and sell to the underwriters named in Schedule II hereto US Airways Pass Through Certificates, Series 2012-2A-O (the “Class A Certificates”) and US Airways Pass Through Certificates, Series 2012-2B-O (the “Class B Certificates” and, together with the Class A Certificates, the “Certificates”), in the aggregate face amounts and with the stated interest rates and final expected distribution dates set forth on Schedule I hereto on the terms and conditions stated herein.

The Certificates will be issued pursuant to a Pass Through Trust Agreement, dated December 21, 2010 (the “Basic Agreement”), between the Company and the Trustee, as supplemented with respect to the issuance of each class of Certificates by a separate Pass Through Trust Supplement to be dated as of the Closing Date (as defined below) (individually, an “Original Trust Supplement”), between the Company and the Trustee (the Basic Agreement as supplemented by each such Original Trust Supplement being referred to herein individually as an “Original Pass Through Trust Agreement”). The Original Trust Supplements are related to the creation and administration of the US Airways Pass Through Trust 2012-2A-O (the “Class A Trust”) and the US Airways Pass Through Trust 2012-2B-O (the “Class B Trust” and, together with the Class A Trust, the “Original Trusts”). As used herein, unless the context otherwise requires, the term “Underwriters” shall mean the firms named as Underwriters in Schedule II, and the term “you” shall mean, collectively, Citigroup Global Markets Inc. (“Citigroup”), ▇▇▇▇▇▇▇, Sachs & Co. (“GS”) and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC (“MS”).

The cash proceeds of the offering of Certificates by each Original Trust will be paid to Wilmington Trust Company, as escrow agent (the “Escrow Agent”), under an Escrow and Paying Agent Agreement to be dated as of the Closing Date (each, an “Escrow Agreement”) among the Escrow Agent, the representatives of the Underwriters, the Trustee of such Original Trust and Wilmington Trust Company, as paying agent (the “Paying Agent”), for the benefit of the holders of the Certificates issued by such Original Trust. The Escrow Agent will deposit such cash proceeds (each, a “Deposit”) with The Bank of New York Mellon, as depositary (the “Depositary”), in accordance with a Deposit Agreement relating to such Original Trust (each, a “Deposit Agreement”), and, subject to the fulfillment of certain conditions, will withdraw Deposits upon request to allow the Trustee to purchase Equipment Notes (as defined in the Note Purchase Agreement (as defined below)) from time to time pursuant to a Note Purchase Agreement to be dated as of the Closing Date (the “Note Purchase Agreement”) among the Company, Wilmington Trust Company, as Trustee of each of the Original Trusts, as Subordination Agent (as hereinafter defined) and as Paying Agent, and the Escrow Agent. Each Escrow Agent will issue receipts to be attached to each related Certificate (“Escrow Receipts”) representing each holder’s interest in amounts deposited with such Escrow Agent with respect to the related class of Certificates and will pay to such holders through the related Paying Agent interest accrued on the Deposits and received by such Paying Agent pursuant to the related Deposit Agreement at a rate per annum equal to the interest rate applicable to the corresponding Certificates. The Equipment Notes will be guaranteed by US Airways Group, Inc., a Delaware corporation (the “Parent Guarantor”), as described in the Guarantee dated the Closing Date (the “Guarantee”) of the Parent Guarantor covering the Guaranteed Obligations (as defined in the Guarantee).

Upon the earlier of (i) the first business day after December 2, 2013 and (ii) the fifth business day following the occurrence of a Triggering Event (as defined in the Intercreditor Agreement) (such business day, the “Trust Transfer Date”), or, if later, the date on which all of the conditions set forth in Section 7.01 of the Original Trust Supplements have been satisfied, each of the Original Trusts will transfer and assign all of its assets and rights to a newly-created

successor trust with substantially identical terms except as described in the Prospectus (as hereinafter defined) (each, a “Successor Trust” and, together with the Original Trusts, the “Trusts”) governed by the Basic Agreement, as supplemented with respect to each class of Certificates by a separate Pass Through Trust Supplement (individually, a “Successor Trust Supplement”), between the Company and the Wilmington Trust Company, as trustee (the Basic Agreement, as supplemented by each such Successor Trust Supplement, being referred to herein individually as a “Successor Pass Through Trust Agreement” and, together with the Original Pass Through Trust Agreements, the “Designated Agreements”). Each Certificate outstanding on the Trust Transfer Date will represent the same interest in the relevant Successor Trust as the Certificate represented in the Original Trust.

Certain amounts of interest payable on the Certificates issued by the Class A Trust and the Class B Trust will be entitled, in each case, to the benefits of a separate liquidity facility. Landesbank Hessen-Thüringen Girozentrale (the “Liquidity Provider”) will enter into separate revolving credit agreements with respect to the Class A Trust and the Class B Trust (collectively, the “Liquidity Facilities”) to be dated as of the Closing Date for the benefit of the holders of the Certificates issued by such Trusts. 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 among the Trustees, Wilmington Trust Company, as subordination agent and trustee thereunder (the “Subordination Agent”), and the Liquidity Provider (the “Intercreditor Agreement”).

4. Certain Covenants of the Company and Parent Guarantor. Each of the Company and the Parent Guarantor covenants with each Underwriter as follows:

(a) If, during such period after the first date of the public offering of the Certificates as, in the opinion of counsel for the Underwriters, 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 Certificates by an underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Registration Statement or the Prospectus in order to make the statements therein, 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, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Registration Statement or Prospectus to comply with applicable law, the Company or the Parent Guarantor, as the case may be, shall forthwith prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses you will furnish to the Company and the Parent Guarantor) to which Certificates may have been sold by 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, be misleading or so that the Registration Statement or Prospectus as amended or supplemented, will comply with applicable law.

(b) Before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus in a manner that would affect the offering of the Certificates, to furnish to you a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the Underwriters reasonably object; provided that, if in the opinion of counsel to the Company, any such amendment or supplement shall be required by law or regulation to be filed, that the Company or the Parent Guarantor, as the case may be, shall be permitted to make such filing after taking into account such comments as the Underwriters and their counsel may

reasonably make on the content, form or other aspects of such proposed amendment or supplement; and to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such rule.

(c) To furnish to you, upon request, without charge, a signed copy of the Registration Statement (including exhibits thereto) and to deliver to the Underwriters during the period mentioned in Section 4(a) or 4(f) hereto as many copies of the Time of Sale Prospectus, the Prospectus, any documents incorporated by reference therein and any supplements and amendments thereto or to the Registration Statement as you may reasonably request.

(d) Promptly following the execution of this Agreement, to prepare a Prospectus that complies with the Securities Act and that sets forth the face amount of the Certificates and their terms (including, without limitation, the terms of the Escrow Receipts attached thereto) not otherwise specified in the preliminary prospectus or the Basic Prospectus included in the Registration Statement, the name of each Underwriter and the 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 any delayed delivery arrangements, and such other information as you, the Company, and the Parent Guarantor deem appropriate in connection with the offering of the Certificates. The Company will timely transmit copies of the Prospectus to the Commission for filing pursuant to Rule 424 under the Securities Act.

(e) To furnish to you a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company or the Parent Guarantor and not to use or refer to any proposed free writing prospectus to which the Underwriters reasonably object; provided that, if in the opinion of counsel to the Company, any such free writing prospectus shall be required by law or regulation to be used, that the Company or the Parent Guarantor, as the case may be, shall be permitted to use such free writing prospectus after taking into account such comments as the Underwriters and their counsel may reasonably make on the content, form or other aspects of such proposed free writing prospectus.

(f) If the Time of Sale Prospectus or any “issuer free writing prospectus” is being used to solicit offers to buy the Certificates at a time when the 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 under which they were made, not misleading, 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, in the opinion of counsel for the Underwriters, it is necessary

to amend or supplement the Time of Sale Prospectus or any “issuer free writing prospectus” to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer 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 the Time of Sale Prospectus or such “issuer free writing prospectus” is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus or such “issuer free writing prospectus,” as 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) To take all reasonable actions to qualify the Certificates for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Underwriters shall reasonably request; provided that neither the Company nor the Parent Guarantor shall be required to register as a foreign corporation or file any general consent to service of process or subject itself to any additional taxation.

(h) Between the date of this Agreement and the Closing Date, the Company and the Parent Guarantor shall not, without your prior written consent, offer, sell or enter into any agreement to sell any equipment notes, pass through certificates, equipment trust certificates or equipment purchase certificates secured by aircraft owned by the Company or the Parent Guarantor (or rights relating thereto).

(i) To prepare a final term sheet relating to the offering of the Certificates in the form of Annex A hereto 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 Certificates.

(l) If the third anniversary of the initial effective date of the Registration Statement occurs before all the Certificates have been sold by the Underwriters, prior to the third anniversary the Company and the Parent Guarantor shall file a new shelf registration statement and take any other action reasonably necessary to permit the public offering of the Certificates to continue without interruption; provided that such requirement to file a new registration statement shall not require the Company or the

Parent Guarantor to file any registration statement other than on Form S-3 (or any successor form); references herein to the Registration Statement shall include the new registration statement declared effective by the Commission.

5. Certain Covenants of the Underwriters. Each Underwriter severally covenants with the Company and the Parent Guarantor not to take any action that would result in the Company or the Parent Guarantor being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company or the Parent Guarantor thereunder, but for the action of that Underwriter. The Underwriters severally acknowledge and agree that, except as set forth in Schedule IV hereto, neither the Company nor the Parent Guarantor has authorized or approved any “issuer information” for use in any free writing prospectus.

6. Indemnification and Contribution. (a) Each of the Company and the Parent Guarantor, jointly and severally, agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities 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 or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company or Parent Guarantor information that the Company or Parent 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 (other than with respect to the Registration Statement, in the light of the circumstances under which they were made) not misleading, except insofar as such 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 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”) or the Depositary Information.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company and the Parent Guarantor, and their respective directors, officers who sign the Registration Statement and each person, if any, who controls the Company and the Parent 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 Parent 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

Section 6(a) or 6(b), 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 to so notify the indemnifying party (i) shall not relieve such indemnifying party from any liability that it may have to any indemnified party under Section 6(a) or 6(b) above unless and to the extent the indemnifying party did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) shall not, in any event, relieve such indemnifying party from any liability that it may have to any indemnified party otherwise than under such subsection. The indemnifying party, upon request of the indemnified party, shall 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 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 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 respect of the legal expenses of any indemnified party 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 you, in the case of parties indemnified pursuant to Section 6(a), and by the Company, in the case of parties indemnified pursuant to Section 6(b). 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 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, 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 30 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. 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 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 a failure to act by, or on behalf of, any indemnified party.

(d) To the extent the indemnification provided for in Section 6(a) or 6(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each 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 Parent Guarantor on the one hand and the Underwriters on the other hand from the offering of the Certificates or (ii) if the allocation provided by clause 6(d)(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 6(d)(i) above but also the relative fault of the Company and the Parent Guarantor on the one hand and of 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 Parent Guarantor on the one hand and the Underwriters on the other hand in connection with the offering of such Certificates shall be deemed to be in the same respective proportions as the proceeds from the offering of such Certificates received by the related Original Trusts (before deducting expenses), less the 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 Certificates. The relative fault of the Company and the Parent 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 Parent Guarantor or by the Underwriters 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 face amount of Certificates they have purchased hereunder, and not joint.

(e) The Company, the Parent 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 this purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 6(d) 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 price at which the Certificates underwritten by it and distributed to the public were offered 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. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 6 and the representations, warranties and other statements of the Company and the Parent 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, any person controlling any Underwriter or any affiliate of any Underwriter or by or on behalf of the Company, the Parent Guarantor, their respective officers or directors or any person controlling the Company or the Parent Guarantor and (iii) acceptance of and payment for any of the Certificates.

7. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Certificates hereunder and the aggregate face amount of the Certificates that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total face amount of the Certificates, you may make arrangements satisfactory to the Company for the purchase of such Certificates by other persons, 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 Certificates that such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate face amount of the Certificates with respect to which such default or defaults occurs exceeds 10% of the total face amount of the Certificates and arrangements satisfactory to you and the Company for purchase of such Certificates by other persons are not made within 36 hours after such default, then the Company shall be entitled to a further period of 36 hours within which to procure other persons reasonably satisfactory to the non-defaulting Underwriters to purchase such Certificates. If, after giving effect to any such arrangements for the purchase of the Certificates of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company, the aggregate face amount of such Certificates that remains unpurchased exceeds 10% of the total face amount of the Certificates, then this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, 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 and the Parent Guarantor, and their 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 Parent Guarantor or any of their respective representatives, officers or directors or any controlling person and will survive delivery of and payment for the Certificates. If for any reason the purchase of the Certificates by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid by it pursuant to Section 10 hereof (other than any reimbursement of out-of-pocket expenses (including reasonable fees and disbursements of counsel) of the Underwriters) and the respective obligations of the Company and the Underwriters pursuant to Section 6 hereof shall remain in effect. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company or the Parent Guarantor to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or the Parent Guarantor shall be unable to perform its obligations under this Agreement, the Company and the

Parent Guarantor, jointly and severally, will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

9. Termination. This Agreement shall be subject to termination by notice given by you 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 of the Parent 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, 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 your judgment, is material and adverse or (v) any material disruption in securities settlement, payment or clearance services in the United States that would materially impair settlement and clearance with respect to the Certificates 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 specified in clauses (a)(i) through (v) makes it, in your judgment, impracticable or inadvisable to market the Certificates on the terms and in the manner contemplated in the Time of Sale Prospectus.

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

(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 Certificates (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 Certificates and the Operative Agreements;

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

(vi) reasonable fees and disbursements of the counsel and accountants for the Company;

(vii) to the extent the Company is so required under any Operative Agreement to which it is a party, the fees and expenses of the Mortgagee, the Subordination Agent, the Trustees, the Paying Agents, the Escrow Agents, the Depositary and the Liquidity Provider and the reasonable fees and disbursements of their respective counsel;

(viii) fees charged by rating agencies for rating the Certificates (including annual surveillance fees related to the Certificates as long as they are outstanding);

(ix) reasonable fees and disbursements of Milbank, Tweed, ▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, counsel for the Underwriters;

(x)

all fees and expenses relating to appraisals of the Aircraft; and
