 DEPOSIT AGREEMENT (Class A) dated as of May 14, 2012 (as amended, modified or
supplemented from time to time, this “Agreement”) between WELLS FARGO BANK NORTHWEST, NATIONAL ASSOCIATION, a national banking association, as Escrow Agent under the Escrow and Paying Agent Agreement referred to below (in such
capacity, together with its successors in such capacity, the “Escrow Agent”), and NATIXIS S.A., acting through its New York Branch, a société anonyme organized and existing under the laws of France and licensed
under the laws of the State of New York, as depositary bank (the “Depositary”). 
 W I T
N E S S E T H 
 WHEREAS, US Airways, Inc. (“US Airways”) and
Wilmington Trust Company, not in its individual capacity except as otherwise expressly provided therein, but solely as trustee (in such capacity, together with its successors in such capacity, the “Pass Through Trustee”) have
entered into a Trust Supplement, dated as of May 14, 2012 (the “Trust Supplement”) to the Pass Through Trust Agreement dated as of December 21, 2010 (together, as amended, modified or supplemented from time to time in
accordance with the terms thereof, the “Pass Through Trust Agreement”) relating to US Airways Pass Through Trust 2012-1A-O pursuant to which the US Airways Pass Through Trust, Series 2012-1A-O Certificates referred to therein (the
“Certificates”) are being issued (the date of such issuance, the “Issuance Date”); 
 WHEREAS,
US Airways and Morgan Stanley & Co. LLC, Citigroup Global Markets Inc. and Goldman, Sachs & Co., as representatives of the several Underwriters (collectively, the “Underwriters” and, together with their respective
transferees and assigns as registered owners of the Certificates, the “Investors”) have entered into an Underwriting Agreement dated as of April 30, 2012 pursuant to which the Pass Through Trustee will issue and sell the
Certificates to the Underwriters; 
 WHEREAS, US Airways, the Pass Through Trustee, two other pass through trustees and certain
other persons concurrently herewith are entering into the Note Purchase Agreement, dated as of the date hereof (the “Note Purchase Agreement”), pursuant to which the Pass Through Trustee has agreed to acquire from time to time on or
prior to the Delivery Period Termination Date (as defined in the Note Purchase Agreement) equipment notes (the “Equipment Notes”) issued to finance certain aircraft currently owned by US Airways and certain other aircraft to be
acquired by US Airways, as owner, utilizing a portion of the proceeds from the sale of the Certificates (the “Net Proceeds”); 
 WHEREAS, the Escrow Agent, the Underwriters, the Pass Through Trustee and Wilmington Trust Company, as paying agent for the Escrow Agent (in such capacity, together with its successors in such capacity,
the “Paying Agent”) concurrently herewith are entering into an Escrow and Paying Agent Agreement, dated as of the date hereof (as amended, modified or supplemented from time to time in accordance with the terms thereof, the
“Escrow and Paying Agent Agreement”); and 
 WHEREAS, the Underwriters and the Pass Through Trustee intend that
the Net Proceeds be held in escrow by the Escrow Agent on behalf of the Investors pursuant to the 

 
Escrow and Paying Agent Agreement, subject to withdrawal upon request of and proper certification by the Pass Through Trustee for the purpose of purchasing Equipment Notes, and that pending such
withdrawal the Net Proceeds be deposited by the Escrow Agent with the Depositary pursuant to this Agreement, which provides for the Depositary to pay interest for distribution to the Investors and to establish accounts from which the Escrow Agent
shall make withdrawals upon request of and proper certification by the Pass Through Trustee. 
 NOW, THEREFORE, in consideration
of the obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 

SECTION 1.1 Acceptance of Depositary. The Depositary hereby agrees to act as depositary bank as provided herein and in connection
therewith to accept all amounts to be delivered to or held by the Depositary pursuant to the terms of this Agreement. The Depositary further agrees to hold, maintain and safeguard the Deposits and the Accounts (as defined below) during the term of
this Agreement in accordance with the provisions of this Agreement. The Escrow Agent shall not have any right to withdraw, assign or otherwise transfer moneys held in the Accounts except as permitted by this Agreement. 

SECTION 1.2 Establishment of Accounts. The Escrow Agent hereby instructs the Depositary, and the Depositary agrees, to establish
the separate deposit accounts listed on Schedule I hereto and to establish such additional separate deposit accounts as may be required in connection with the deposits contemplated by Section 2.4 hereof (each, an “Account” and
collectively, the “Accounts”), each in the name of the Escrow Agent and all on the terms and conditions set forth in this Agreement. 
 SECTION 2.1 Deposits. The Escrow Agent shall direct the Underwriters to deposit with the Depositary on the date of this Agreement (the “Deposit Date”) in Federal (same day) funds
by wire transfer to: JPMorgan Chase Bank, National Association, ABA No. 021-000-021 for the account of Natixis, NY Branch, Account Number: 544-7-75330, Reference: US Airways 2012-1 EETC Depositary, and the Depositary shall accept from the
Underwriters, on behalf of the Escrow Agent, the sum of US$379,785,000. Upon acceptance of such sum, the Depositary shall (i) establish each of the deposits specified in Schedule I hereto maturing on June 30, 2013 (including any deposit
made pursuant to Section 2.4 hereof, individually, a “Deposit” and, collectively, the “Deposits”) and (ii) credit each Deposit to the related Account as set forth therein. No amount shall be deposited in
any Account other than the related Deposit. 
 SECTION 2.2 Interest. Each Deposit shall bear interest from and including
the date of deposit to but excluding the date of withdrawal at the rate of 5.90% per annum (computed on the basis of a year of twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent semi-annually in arrears on each
April 1 and October 1, commencing on October 1, 2012 (each, an “Interest Payment Date”), and on the date of the Final Withdrawal (as defined below), or the date of the Replacement Withdrawal (as defined below), as
applicable, all in accordance with the terms of this Agreement (whether or not any such Deposit is withdrawn on an Interest Payment Date). Interest accrued on any Deposit that is withdrawn pursuant to a Notice of Purchase Withdrawal (as defined
below) shall be paid on the next Interest Payment Date, notwithstanding any intervening Final Withdrawal (as defined below).

 SECTION 2.3 Withdrawals. (a) On and after the date seven days after the establishment
of any Deposit, the Escrow Agent may, by providing at least three Business Days’ prior notice of withdrawal to the Depositary in the form of Exhibit A hereto (a “Notice of Purchase Withdrawal”), withdraw not less than the
entire balance of such Deposit, except that at any time prior to the actual withdrawal of such Deposit, the Escrow Agent or the Pass Through Trustee may, by notice to the Depositary, which notice has been actually received by the Depositary prior to
such actual withdrawal, cancel such withdrawal (including on the scheduled date therefor), and thereafter such Deposit shall continue to be maintained by the Depositary in accordance with the original terms thereof. Following such withdrawal the
balance in the related Account shall be zero and the Depositary shall close such Account. As used in this Agreement, “Business Day” means any day, other than a Saturday, Sunday or other day on which commercial banks are authorized
or required by law to close in New York, New York, Phoenix, Arizona or Wilmington, Delaware. The Depositary may waive the foregoing requirement that any Deposit can only be withdrawn on or after seven days after the establishment thereof, and may
instead reserve the right, upon at least 14 days’ prior written notice to US Airways, the Escrow Agent and the Pass Through Trustee, to require seven days’ notice for any withdrawal. 

(b) (i) The Escrow Agent may, by providing at least 15 days’ prior notice of withdrawal to the Depositary in the form of Exhibit B
hereto (a “Notice of Final Withdrawal”), withdraw the entire amount of all of the remaining Deposits together with the payment by the Depositary of all accrued and unpaid interest on such Deposits to but excluding the specified date
of withdrawal (a “Final Withdrawal”), on such date as shall be specified in such Notice of Final Withdrawal. If a Notice of Final Withdrawal has not been given to the Depositary on or before June 10, 2013 and there are
unwithdrawn Deposits on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on June 30, 2013. 
 (ii) The Escrow Agent may, by providing at least five Business Days’ prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a “Notice of Replacement
Withdrawal”), withdraw the entire amount of all Deposits then held by the Depositary together with all accrued and unpaid interest on such Deposits (including Deposits previously withdrawn pursuant to a Notice of Purchase Withdrawal) to but
excluding the specified date of withdrawal (a “Replacement Withdrawal”), on such date as shall be specified in such Notice of Replacement Withdrawal. 
 (c) If the Depositary receives a duly completed Notice of Purchase Withdrawal, Notice of Final Withdrawal or Notice of Replacement Withdrawal (each, a “Withdrawal Notice”) complying with
the provisions of this Agreement, it shall make the payments specified therein in accordance with the provisions of this Agreement. Notwithstanding anything to the contrary contained in this Agreement, in no event shall the Depositary be required,
pursuant to any Withdrawal Notice or otherwise, to make payments hereunder on or in respect of any Deposit in excess of the amount of such Deposit together with accrued interest thereon as provided in this Agreement. 

SECTION 2.4 Other Accounts. On the date of withdrawal of any Deposit (other than the date of the Final Withdrawal or Replacement
Withdrawal), the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow Agent, shall re-deposit with the Depositary any 

  
 -3-

 
portion thereof not used to acquire Equipment Notes and the Depositary shall accept the same for deposit hereunder. Any sums so received for deposit shall be established as a new Deposit and
credited to a new Account, all as more fully provided in Section 2.1 hereof, and thereafter the provisions of this Agreement shall apply thereto as fully and with the same force and effect as if such Deposit had been established on the Deposit
Date except that (i) such Deposit may not be withdrawn prior to the date seven days after the establishment thereof and (ii) such Deposit shall mature on June 30, 2013 and bear interest as provided in Section 2.2. The Depositary
shall promptly give notice to the Escrow Agent of receipt of each such re-deposit and the account number assigned thereto. 

SECTION 3. Termination. This Agreement shall terminate on the fifth Business Day after the later of the date on which (i) all
of the Deposits shall have been withdrawn and paid as provided herein without any re-deposit and (ii) all accrued and unpaid interest on the Deposits shall have been paid as provided herein, but in no event prior to the date on which the
Depositary shall have performed in full its obligations hereunder. 
 SECTION 4. Payments. All payments made by the
Depositary hereunder shall be paid in United States Dollars and immediately available funds by wire transfer (i) in the case of accrued interest on the Deposits payable under Section 2.2 hereof or any Final Withdrawal, directly to the
Paying Agent at Wilmington Trust Company, Wilmington, DE, ABA# 031100092, Account No. 101449-000, Attention: Robert Hines, Telephone No.: (302) 636-6197, Reference: US Airways 2012-1 Paying Agent Account, or to such other account as the
Paying Agent may direct from time to time in writing to the Depositary and the Escrow Agent and (ii) in the case of any withdrawal of one or more Deposits pursuant to a Notice of Purchase Withdrawal or Notice of Replacement Withdrawal, directly
to or as directed by the Pass Through Trustee as specified and in the manner provided in such Notice of Purchase Withdrawal or Notice of Replacement Withdrawal. The Depositary hereby waives any and all rights of set-off, combination of accounts,
right of retention or similar right (whether arising under applicable law, contract or otherwise) it may have against the Deposits howsoever arising. To the extent permitted by applicable law, all payments on or in respect of each Deposit shall be
made free and clear of and without reduction for or on account of any and all taxes, levies or other impositions or charges (collectively, “Taxes”). However, if the Depositary (or if the Paying Agent shall have notified the
Depositary that the Paying Agent (pursuant to Section 2.04 of the Escrow and Paying Agent Agreement)) shall be required by law to deduct or withhold any Taxes from or in respect of any sum payable hereunder, the Depositary shall (i) make,
or cause to be made, such deductions or withholding and (ii) pay, or cause to be paid, the full amount deducted or withheld (including in respect of such additional amounts) to the competent taxation authority and (iii) if the Taxes
required to be deducted or withheld are imposed by France or any political subdivision thereof (other than pursuant to any inter-governmental agreement with the United States pursuant to FATCA or under implementing legislation or administrative
rules thereunder), pay such additional amounts as may be necessary in order that the actual amount received by the designated recipient of such sum under this Agreement or the Escrow and Paying Agent Agreement after such deduction or withholding
equals the sum it would have received had no such deduction or withholding been required. If the date on which any payment due on any Deposit would otherwise fall on a day which is not a Business Day, such payment shall be made on the next
succeeding Business Day, and no additional interest shall accrue in respect of such 

  
 -4-

 
extension. For purposes of this Section 4, “FATCA” means Sections 1471 through 1474 of the Code, as of the date of this Agreement (or any amended or successor version that
is substantively comparable and not materially more onerous to comply with) and any current or future regulations or official interpretations thereof. 
 SECTION 5. Representation and Warranties. The Depositary hereby represents and warrants to US Airways, the Escrow Agent, the Pass Through Trustee and the Paying Agent that: 

(a) it is a société anonyme duly organized and validly existing in good standing under the laws of
France and is duly licensed to conduct banking business in the State of New York; 
 (b) it has full power,
authority and legal right to conduct its business and operations as currently conducted and to enter into and perform its obligations under this Agreement; 
 (c) the execution, delivery and performance of this Agreement have been duly authorized by all necessary corporate action on the part of it and do not require any stockholder approval, or approval or
consent of any trustee or holder of any indebtedness or obligations of it, and this Agreement has been duly executed and delivered by it and constitutes its legal, valid and binding obligations enforceable against it in accordance with the terms
hereof; 
 (d) no authorization, consent or approval of or other action by, and no notice to or filing with, any
United States federal or state governmental authority or regulatory body is required for the execution, delivery or performance by it of this Agreement; 
 (e) neither the execution, delivery or performance by it of this Agreement, nor compliance with the terms and provisions hereof, conflicts or will conflict with or results or will result in a breach or
violation of any of the terms, conditions or provisions of, or will require any consent or approval under, any law, governmental rule or regulation or the charter documents, as amended, or bylaws, as amended, of it or any similar instrument binding
on it or any order, writ, injunction or decree of any court or governmental authority against it or by which it or any of its properties is bound or of any indenture, mortgage or contract or other agreement or instrument to which it is a party or by
which it or any of its properties is bound, or constitutes or will constitute a default thereunder or results or will result in the imposition of any lien upon any of its properties; and 

(f) there are no pending or, to its knowledge, threatened actions, suits, investigations or proceedings (whether or not
purportedly on behalf of it) against or affecting it or any of its property before or by any court or administrative agency which, if adversely determined, (i) would adversely affect the ability of it to perform its obligations under this
Agreement or (ii) would call into question or challenge the validity of this Agreement or the enforceability hereof in accordance with the terms hereof, nor is 

  
 -5-

 
the Depositary in default with respect to any order of any court, governmental authority, arbitration board or administrative agency so as to adversely affect its ability to perform its
obligations under this Agreement. 
 SECTION 6. Transfer. Neither party hereto shall be entitled to assign or otherwise
transfer this Agreement (or any interest herein) other than (in the case of the Escrow Agent) to a successor escrow agent under the Escrow and Paying Agent Agreement and other than (in the case of the Depositary) to any entity into which the
Depositary shall merge or with which it shall be consolidated, and any purported assignment in violation thereof shall be void. This Agreement shall be binding upon the parties hereto and their respective successors and (in the case of the Escrow
Agent) permitted assigns. Upon the occurrence of the Transfer (as defined below) contemplated by the Assignment and Assumption Agreement (as defined below), the Pass Through Trustee shall (without further act) be deemed to have transferred all of
its right, title and interest in and to this Agreement to the trustee of the Successor Trust (as defined below) and, thereafter, the trustee of the Successor Trust shall be deemed to be the “Pass Through Trustee” hereunder with the rights
of the “Pass Through Trustee” hereunder, and each reference herein to “US Airways Pass Through Trust 2012-1A-O” shall be deemed to be a reference to “US Airways Pass Through Trust 2012-1A-S”. The Escrow Agent and the
Depositary hereby acknowledge and consent to the Transfer contemplated by the Assignment and Assumption Agreement. For the purposes of this Section 6, “Transfer” means the transfer contemplated by the Assignment and Assumption
Agreement; “Assignment and Assumption Agreement” means the Assignment and Assumption Agreement to be entered into between the Pass Through Trustee and the trustee of the Successor Trust, substantially in the form of Exhibit C to the
Trust Supplement; and “Successor Trust” means the US Airways Pass Through Trust 2012-1A-S.

Agreement shall be in writing (including by facsimile) and shall be deemed to be given and effective upon receipt thereof. All notices shall be sent to (x) in the case of the Depositary, Natixis S.A., New York Branch, 9 West 57th Street, 35th

Agreement, the Escrow Agent has delivered to the Depositary a certificate containing specimen signatures of the representatives of the Escrow

from the Escrow Agent to the contrary. 
 The Depositary shall have the right, but shall not be required, to rely upon and
comply with instructions and directions sent by e-mail by persons believed by the Depositary to be authorized to give instructions and directions on behalf of the Escrow Agent. The Depositary shall have no duty or obligation to verify or confirm
that the person who sent such instructions or directions is, in fact, a person authorized to give instructions or directions on behalf of the Escrow Agent; and the Depositary shall have no liability for any losses, liabilities, costs or expenses
incurred or sustained by the Escrow Agent as a result of such reliance upon or compliance with such instructions or directions. The Escrow Agent agrees to assume all risks arising out of the use of e-mail to submit instructions and directions to the
Depositary, including without limitation the risk of the Depositary acting on unauthorized instructions, and the risk of interception and misuse by third parties. 
 SECTION 9. Obligations Unconditional. The Depositary hereby acknowledges and agrees that its obligation to repay each Deposit together with interest thereon as provided herein is absolute,
irrevocable and unconditional and constitutes a full recourse obligation of the Depositary enforceable against it to the full extent of all of its assets and properties. 
 SECTION 10. Entire Agreement. This Agreement (including all attachments hereto) sets forth all of the promises, covenants, agreements, conditions and understandings between the Depositary and the
Escrow Agent with respect to the subject matter hereof and supersedes all prior and contemporaneous agreements and undertakings, inducements or conditions, express or implied, oral or written. 

SECTION 11. Governing Law. This Agreement, and the rights and obligations of the Depositary and the Escrow Agent with respect to
the Deposits, shall be governed by, and construed in accordance with, the law of the State of New York and subject to the provisions of Regulation D of the Board of Governors of the Federal Reserve System (or any successor), as the same may be
modified and supplemented and in effect from time to time. 
 SECTION 12. Submission to Non-Exclusive Jurisdiction in New
York. Each of the parties hereto, to the extent it may do so under applicable law, hereby (a) irrevocably submits itself to the non-exclusive jurisdiction of the courts of the State of New York sitting in the City of New York and to the
non-exclusive jurisdiction of the United States District Court for the Southern District of New York, for the purposes of any suit, action or other proceeding arising out of this Agreement, the subject matter hereof or any of the transactions
contemplated hereby brought by any party or parties hereto, or their successors or permitted assigns and (b) waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, that the suit,
action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof or any of the transactions contemplated hereby may not be enforced in or by
such courts. 

  
 -7-

 SECTION 13. Waiver of Jury Trial Right. EACH OF THE DEPOSITARY AND THE ESCROW AGENT
ACKNOWLEDGES AND ACCEPTS THAT IN ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT SUCH PARTY IRREVOCABLY WAIVES ITS RIGHT TO A TRIAL BY JURY. 
 SECTION 14. Counterparts. This Agreement may be executed in one or more counterparts, all of which taken together shall constitute one instrument. 

SECTION 15. Rights of Receiptholders. The Depositary acknowledges that, if the Depositary shall fail to pay when due hereunder any
interest on the Deposits or the Final Withdrawal, the “Receiptholders” (as defined in the Escrow and Paying Agent Agreement) shall have the right to claim directly against the Depositary and that any such claim shall not be subject to
defenses that the Depositary may have against the Escrow Agent. 
 SECTION 16. Limitation on Damages. In no event shall
the Depositary be responsible or liable for special, indirect, punitive, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit, whether or not foreseeable) suffered by Escrow Agent or any of the
Receiptholders (as defined in the Escrow and Paying Agent Agreement) in connection with this Agreement or the transaction contemplated or any relationships established by this Agreement irrespective of whether the Depositary has been advised of the
likelihood of such loss or damage and regardless of the form of action. In the event of any conflict or inconsistency between any provision in this Agreement and a provision in any other document, the provisions of this Agreement shall control.

 SECTION 17. Miscellaneous. (a) The Depositary shall have only those duties as are specifically and expressly provided
herein and no other duties shall be implied. The Depositary may rely upon and shall not be liable for acting or refraining from acting upon any written notice, document, instruction or request furnished to it hereunder and believed by it to be
genuine and to have been signed or presented by the Escrow Agent without inquiry and without requiring substantiating evidence of any kind. The Depositary shall be under no duty to inquire into or investigate the validity, accuracy or content of any
such document, notice, instruction or request. The Depositary shall have no duty to solicit any payments, including, without limitation, the Deposits. 
 (b) The Depositary shall not be liable for any action taken, suffered or omitted to be taken by it in good faith except to the extent that a final adjudication of a court of competent jurisdiction
determines that the Depositary’s gross negligence or willful misconduct was the primary cause of any loss. The Depositary may execute any of its powers and perform any of its duties hereunder directly or through attorneys, and shall be liable
only for its gross negligence or willful misconduct (as finally adjudicated in a court of competent jurisdiction) in the selection of any such attorney. The Depositary may consult with counsel, accountants and other skilled persons to be selected
and retained by it. The Depositary shall not be liable for any action taken, suffered or omitted to be taken by it in accordance with, or in reliance upon, the advice or opinion of any such counsel, accountants or other skilled persons. In the event
that the Depositary shall be uncertain or believe there is some ambiguity as to its duties or rights hereunder or shall receive instructions, claims or demands from any party hereto which, in its opinion, conflict with any of the provisions of this
Agreement, it shall be entitled to refrain from 

  
 -8-

 
taking any action and its sole obligation shall be to keep safely all property held hereunder until it shall be given a direction in writing by the Escrow Agent which eliminates such ambiguity or
uncertainty to the satisfaction of Depositary or by a final and non-appealable order or judgment of a court of competent jurisdiction. 
 (c) (i) Section 326 of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”) requires the
Depositary to implement reasonable procedures to verify the identity of any person that opens a new account with it. Accordingly, the Escrow Agent acknowledges that Section 326 of the USA PATRIOT Act and the Depositary’s identity
verification procedures require the Depositary to obtain information which may be used to confirm the Escrow Agent’s identity including without limitation name, address and organizational documents (“identifying information”).
The Escrow Agent agrees to provide the Depositary with and consent to the Depositary obtaining from third parties any such identifying information required as a condition of opening an account with or using any service provided by the Depositary.

 (ii) Depositary agrees that upon the reasonable request of the Escrow Agent, it will provide to the Escrow Agent such
information and documents as the Escrow Agent may require (x) to satisfy applicable anti-money laundering laws and regulations, including the USA PATRIOT Act, the regulations administered by the U.S. Department of Treasury’s Office of
Foreign Assets Control (“OFAC”), and other applicable U.S. anti-money laundering laws and regulations (collectively, the “anti-money laundering/OFAC laws”), or (y) to meet the requirements of the Escrow
Agent’s internal know your customer policies and procedures adopted in accordance with the anti-money laundering/OFAC laws. 
 (d) The Escrow Agent has provided the Depositary with its fully executed Internal Revenue Service (“IRS”) Form W-9. The Escrow Agent represents that its correct TIN assigned by the IRS,
or any other taxing authority, is set forth in the delivered form. Any United States federal, state or local income or franchise tax returns required to be filed will, to the greatest extent permitted by applicable law, be prepared and filed by the
Escrow Agent with the IRS and any other taxing authority as required by law. The Escrow Agent acknowledges and agrees that the Depositary shall have no responsibility for the preparation and/or filing of any United States federal, state or local
income, franchise or other tax return with respect to the Deposits or any income earned by the Deposits other than any such responsibility that cannot be assigned to, or assumed by the Escrow Agent under applicable law. 

(e) No party to this Agreement is liable to any other party for losses due to, or if it is unable to perform its obligations under the
terms of this Agreement because of, acts of God, fire, war, terrorism, floods, strikes, electrical outages, equipment or transmission failure, or other causes reasonably beyond its control. If any provision of this Agreement is determined to be
prohibited or unenforceable by reason of any applicable law of a jurisdiction, then such provision shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions
thereof, and any such prohibition or unenforceability in such jurisdiction shall not invalidate or render unenforceable such provisions in any other jurisdiction.

 SECTION 18. Security Procedures. With respect to all funds transfer instructions that
are given pursuant to this Agreement (other than in writing at the time of execution of this Agreement), whether in writing, by facsimile or otherwise, the Depositary is authorized to seek confirmation of such instructions by telephone call-back to
the person or persons designated on Schedule II hereto (“Schedule II”), and the Depositary may rely upon the confirmation of anyone purporting to be the person or persons so designated. Each funds transfer instruction shall be executed by
an authorized signatory, a list of such authorized signatories is set forth on Schedule II. The persons and telephone numbers for call-backs may be changed only in a writing actually received and acknowledged by the Depositary. If the Depositary is
unable to contact any of the authorized representatives identified in Schedule II, the Depositary is hereby authorized to seek confirmation of such instructions by telephone call-back to any one or more of Escrow Agent’s executive officers
(“Executive Officers”), as the case may be, which shall include the titles of Assistant Vice President or Vice President, as the Depositary may select. Such “Executive Officer” shall deliver to the Depositary a fully executed
incumbency certificate, and the Depositary may rely upon the confirmation of anyone purporting to be any such officer. The Depositary and the beneficiary’s bank in any funds transfer may rely solely upon any account numbers or similar
identifying numbers provided by the Escrow Agent to identify (a) the beneficiary, (b) the beneficiary’s bank, or (c) an intermediary bank. The Depositary may apply any of the funds for any payment order it executes using any such
identifying number, even when its use may result in a person other than the beneficiary being paid, or the transfer of funds to a bank other than the beneficiary’s bank or an intermediary bank designated. The Escrow Agent acknowledges that
these security procedures are commercially reasonable. 
 SECTION 19. Head Office Obligations. The Depositary is Natixis
S.A., a French bank (“Natixis”), acting through its New York Branch. The Depositary hereby agrees that, notwithstanding the place of booking or its jurisdiction of incorporation or organization, the obligations of the Depositary
hereunder are also the obligations of the head office of Natixis in Paris, France (the “Head Office”). Accordingly, any beneficiary of this Agreement will be able to proceed directly against the Head Office, if the Depositary
defaults in its obligations to such beneficiary under this Agreement. 
 SECTION 20. Waiver of Immunity. To the extent
that the Depositary or any of its properties has or may hereafter acquire any right of immunity, whether characterized as sovereign immunity or otherwise, and whether under the United States Foreign Sovereign Immunities Act of 1976 (or any successor
legislation) or otherwise, from any legal proceedings, whether in the United States or elsewhere, to enforce or collect upon this Agreement, including, without limitation, immunity from suit or service of process, immunity from jurisdiction or
judgment of any court or tribunal or execution of a judgment, or immunity of any of its property from attachment prior to any entry of judgment, or from attachment in aid of execution upon a judgment, the Depositary hereby irrevocably and expressly
waives any such immunity, and agrees not to assert any such right or claim in any such proceeding, whether in the United States or elsewhere.

 DEPOSIT AGREEMENT (Class B) dated as of May 14, 2012 (as amended, modified or
supplemented from time to time, this “Agreement”) between WELLS FARGO BANK NORTHWEST, NATIONAL ASSOCIATION, a national banking association, as Escrow Agent under the Escrow and Paying Agent Agreement referred to below (in such
capacity, together with its successors in such capacity, the “Escrow Agent”), and NATIXIS S.A., acting through its New York Branch, a société anonyme organized and existing under the laws of France and licensed
under the laws of the State of New York, as depositary bank (the “Depositary”). 
 W I T
N E S S E T H 
 WHEREAS, US Airways, Inc. (“US Airways”) and
Wilmington Trust Company, not in its individual capacity except as otherwise expressly provided therein, but solely as trustee (in such capacity, together with its successors in such capacity, the “Pass Through Trustee”) have
entered into a Trust Supplement, dated as of May 14, 2012 (the “Trust Supplement”) to the Pass Through Trust Agreement dated as of December 21, 2010 (together, as amended, modified or supplemented from time to time in
accordance with the terms thereof, the “Pass Through Trust Agreement”) relating to US Airways Pass Through Trust 2012-1B-O pursuant to which the US Airways Pass Through Trust, Series 2012-1B-O Certificates referred to therein (the
“Certificates”) are being issued (the date of such issuance, the “Issuance Date”); 
 WHEREAS,
US Airways and Morgan Stanley & Co. LLC, Citigroup Global Markets Inc. and Goldman, Sachs & Co., as representatives of the several Underwriters (collectively, the “Underwriters” and, together with their respective
transferees and assigns as registered owners of the Certificates, the “Investors”) have entered into an Underwriting Agreement dated as of April 30, 2012 pursuant to which the Pass Through Trustee will issue and sell the
Certificates to the Underwriters; 
 WHEREAS, US Airways, the Pass Through Trustee, two other pass through trustees and certain
other persons concurrently herewith are entering into the Note Purchase Agreement, dated as of the date hereof (the “Note Purchase Agreement”), pursuant to which the Pass Through Trustee has agreed to acquire from time to time on or
prior to the Delivery Period Termination Date (as defined in the Note Purchase Agreement) equipment notes (the “Equipment Notes”) issued to finance certain aircraft currently owned by US Airways and certain other aircraft to be
acquired by US Airways, as owner, utilizing a portion of the proceeds from the sale of the Certificates (the “Net Proceeds”); 
 WHEREAS, the Escrow Agent, the Underwriters, the Pass Through Trustee and Wilmington Trust Company, as paying agent for the Escrow Agent (in such capacity, together with its successors in such capacity,
the “Paying Agent”) concurrently herewith are entering into an Escrow and Paying Agent Agreement, dated as of the date hereof (as amended, modified or supplemented from time to time in accordance with the terms thereof, the
“Escrow and Paying Agent Agreement”); and 
 WHEREAS, the Underwriters and the Pass Through Trustee intend that
the Net Proceeds be held in escrow by the Escrow Agent on behalf of the Investors pursuant to the 

 
Escrow and Paying Agent Agreement, subject to withdrawal upon request of and proper certification by the Pass Through Trustee for the purpose of purchasing Equipment Notes, and that pending such
withdrawal the Net Proceeds be deposited by the Escrow Agent with the Depositary pursuant to this Agreement, which provides for the Depositary to pay interest for distribution to the Investors and to establish accounts from which the Escrow Agent
shall make withdrawals upon request of and proper certification by the Pass Through Trustee. 
 NOW, THEREFORE, in consideration
of the obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 

SECTION 1.1 Acceptance of Depositary. The Depositary hereby agrees to act as depositary bank as provided herein and in connection
therewith to accept all amounts to be delivered to or held by the Depositary pursuant to the terms of this Agreement. The Depositary further agrees to hold, maintain and safeguard the Deposits and the Accounts (as defined below) during the term of
this Agreement in accordance with the provisions of this Agreement. The Escrow Agent shall not have any right to withdraw, assign or otherwise transfer moneys held in the Accounts except as permitted by this Agreement. 

SECTION 1.2 Establishment of Accounts. The Escrow Agent hereby instructs the Depositary, and the Depositary agrees, to establish
the separate deposit accounts listed on Schedule I hereto and to establish such additional separate deposit accounts as may be required in connection with the deposits contemplated by Section 2.4 hereof (each, an “Account” and
collectively, the “Accounts”), each in the name of the Escrow Agent and all on the terms and conditions set forth in this Agreement. 
 SECTION 2.1 Deposits. The Escrow Agent shall direct the Underwriters to deposit with the Depositary on the date of this Agreement (the “Deposit Date”) in Federal (same day) funds
by wire transfer to: JPMorgan Chase Bank, National Association, ABA No. 021-000-021 for the account of Natixis, NY Branch, Account Number: 544-7-75330, Reference: US Airways 2012-1 EETC Depositary, and the Depositary shall accept from the
Underwriters, on behalf of the Escrow Agent, the sum of US$124,958,000. Upon acceptance of such sum, the Depositary shall (i) establish each of the deposits specified in Schedule I hereto maturing on June 30, 2013 (including any deposit
made pursuant to Section 2.4 hereof, individually, a “Deposit” and, collectively, the “Deposits”) and (ii) credit each Deposit to the related Account as set forth therein. No amount shall be deposited in
any Account other than the related Deposit. 
 SECTION 2.2 Interest. Each Deposit shall bear interest from and including
the date of deposit to but excluding the date of withdrawal at the rate of 8.00% per annum (computed on the basis of a year of twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent semi-annually in arrears on each
April 1 and October 1, commencing on October 1, 2012 (each, an “Interest Payment Date”), and on the date of the Final Withdrawal (as defined below), or the date of the Replacement Withdrawal (as defined below), as
applicable, all in accordance with the terms of this Agreement (whether or not any such Deposit is withdrawn on an Interest Payment Date). Interest accrued on any Deposit that is withdrawn pursuant to a Notice of Purchase Withdrawal (as defined
below) shall be paid on the next Interest Payment Date, notwithstanding any intervening Final Withdrawal (as defined below). 

  
 -2-

 SECTION 2.3 Withdrawals. (a) On and after the date seven days after the establishment
of any Deposit, the Escrow Agent may, by providing at least three Business Days’ prior notice of withdrawal to the Depositary in the form of Exhibit A hereto (a “Notice of Purchase Withdrawal”), withdraw not less than the
entire balance of such Deposit, except that at any time prior to the actual withdrawal of such Deposit, the Escrow Agent or the Pass Through Trustee may, by notice to the Depositary, which notice has been actually received by the Depositary prior to
such actual withdrawal, cancel such withdrawal (including on the scheduled date therefor), and thereafter such Deposit shall continue to be maintained by the Depositary in accordance with the original terms thereof. Following such withdrawal the
balance in the related Account shall be zero and the Depositary shall close such Account. As used in this Agreement, “Business Day” means any day, other than a Saturday, Sunday or other day on which commercial banks are authorized
or required by law to close in New York, New York, Phoenix, Arizona or Wilmington, Delaware. The Depositary may waive the foregoing requirement that any Deposit can only be withdrawn on or after seven days after the establishment thereof, and may
instead reserve the right, upon at least 14 days’ prior written notice to US Airways, the Escrow Agent and the Pass Through Trustee, to require seven days’ notice for any withdrawal. 

(b) (i) The Escrow Agent may, by providing at least 15 days’ prior notice of withdrawal to the Depositary in the form of Exhibit B
hereto (a “Notice of Final Withdrawal”), withdraw the entire amount of all of the remaining Deposits together with the payment by the Depositary of all accrued and unpaid interest on such Deposits to but excluding the specified date
of withdrawal (a “Final Withdrawal”), on such date as shall be specified in such Notice of Final Withdrawal. If a Notice of Final Withdrawal has not been given to the Depositary on or before June 10, 2013 and there are
unwithdrawn Deposits on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on June 30, 2013. 
 (ii) The Escrow Agent may, by providing at least five Business Days’ prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a “Notice of Replacement
Withdrawal”), withdraw the entire amount of all Deposits then held by the Depositary together with all accrued and unpaid interest on such Deposits (including Deposits previously withdrawn pursuant to a Notice of Purchase Withdrawal) to but
excluding the specified date of withdrawal (a “Replacement Withdrawal”), on such date as shall be specified in such Notice of Replacement Withdrawal. 
 (c) If the Depositary receives a duly completed Notice of Purchase Withdrawal, Notice of Final Withdrawal or Notice of Replacement Withdrawal (each, a “Withdrawal Notice”) complying with
the provisions of this Agreement, it shall make the payments specified therein in accordance with the provisions of this Agreement. Notwithstanding anything to the contrary contained in this Agreement, in no event shall the Depositary be required,
pursuant to any Withdrawal Notice or otherwise, to make payments hereunder on or in respect of any Deposit in excess of the amount of such Deposit together with accrued interest thereon as provided in this Agreement. 

SECTION 2.4 Other Accounts. On the date of withdrawal of any Deposit (other than the date of the Final Withdrawal or Replacement
Withdrawal), the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow Agent, shall re-deposit with the Depositary any 

  
 -3-

 
portion thereof not used to acquire Equipment Notes and the Depositary shall accept the same for deposit hereunder. Any sums so received for deposit shall be established as a new Deposit and
credited to a new Account, all as more fully provided in Section 2.1 hereof, and thereafter the provisions of this Agreement shall apply thereto as fully and with the same force and effect as if such Deposit had been established on the Deposit
Date except that (i) such Deposit may not be withdrawn prior to the date seven days after the establishment thereof and (ii) such Deposit shall mature on June 30, 2013 and bear interest as provided in Section 2.2. The Depositary
shall promptly give notice to the Escrow Agent of receipt of each such re-deposit and the account number assigned thereto. 

SECTION 3. Termination. This Agreement shall terminate on the fifth Business Day after the later of the date on which (i) all
of the Deposits shall have been withdrawn and paid as provided herein without any re-deposit and (ii) all accrued and unpaid interest on the Deposits shall have been paid as provided herein, but in no event prior to the date on which the
Depositary shall have performed in full its obligations hereunder. 
 SECTION 4. Payments. All payments made by the
Depositary hereunder shall be paid in United States Dollars and immediately available funds by wire transfer (i) in the case of accrued interest on the Deposits payable under Section 2.2 hereof or any Final Withdrawal, directly to the
Paying Agent at Wilmington Trust Company, Wilmington, DE, ABA# 031100092, Account No. 101450-000, Attention: Robert Hines, Telephone No.: (302) 636-6197, Reference: US Airways 2012-1 Paying Agent Account, or to such other account as the
Paying Agent may direct from time to time in writing to the Depositary and the Escrow Agent and (ii) in the case of any withdrawal of one or more Deposits pursuant to a Notice of Purchase Withdrawal or Notice of Replacement Withdrawal, directly
to or as directed by the Pass Through Trustee as specified and in the manner provided in such Notice of Purchase Withdrawal or Notice of Replacement Withdrawal. The Depositary hereby waives any and all rights of set-off, combination of accounts,
right of retention or similar right (whether arising under applicable law, contract or otherwise) it may have against the Deposits howsoever arising. To the extent permitted by applicable law, all payments on or in respect of each Deposit shall be
made free and clear of and without reduction for or on account of any and all taxes, levies or other impositions or charges (collectively, “Taxes”). However, if the Depositary (or if the Paying Agent shall have notified the
Depositary that the Paying Agent (pursuant to Section 2.04 of the Escrow and Paying Agent Agreement)) shall be required by law to deduct or withhold any Taxes from or in respect of any sum payable hereunder, the Depositary shall (i) make,
or cause to be made, such deductions or withholding and (ii) pay, or cause to be paid, the full amount deducted or withheld (including in respect of such additional amounts) to the competent taxation authority and (iii) if the Taxes
required to be deducted or withheld are imposed by France or any political subdivision thereof (other than pursuant to any inter-governmental agreement with the United States pursuant to FATCA or under implementing legislation or administrative
rules thereunder), pay such additional amounts as may be necessary in order that the actual amount received by the designated recipient of such sum under this Agreement or the Escrow and Paying Agent Agreement after such deduction or withholding
equals the sum it would have received had no such deduction or withholding been required. If the date on which any payment due on any Deposit would otherwise fall on a day which is not a Business Day, such payment shall be made on the next
succeeding Business Day, and no additional interest shall accrue in respect of such 

  
 -4-

 
extension. For purposes of this Section 4, “FATCA” means Sections 1471 through 1474 of the Code, as of the date of this Agreement (or any amended or successor version that
is substantively comparable and not materially more onerous to comply with) and any current or future regulations or official interpretations thereof. 
 SECTION 5. Representation and Warranties. The Depositary hereby represents and warrants to US Airways, the Escrow Agent, the Pass Through Trustee and the Paying Agent that: 

(a) it is a société anonyme duly organized and validly existing in good standing under the laws of
France and is duly licensed to conduct banking business in the State of New York; 
 (b) it has full power,
authority and legal right to conduct its business and operations as currently conducted and to enter into and perform its obligations under this Agreement; 
 (c) the execution, delivery and performance of this Agreement have been duly authorized by all necessary corporate action on the part of it and do not require any stockholder approval, or approval or
consent of any trustee or holder of any indebtedness or obligations of it, and this Agreement has been duly executed and delivered by it and constitutes its legal, valid and binding obligations enforceable against it in accordance with the terms
hereof; 
 (d) no authorization, consent or approval of or other action by, and no notice to or filing with, any
United States federal or state governmental authority or regulatory body is required for the execution, delivery or performance by it of this Agreement; 
 (e) neither the execution, delivery or performance by it of this Agreement, nor compliance with the terms and provisions hereof, conflicts or will conflict with or results or will result in a breach or
violation of any of the terms, conditions or provisions of, or will require any consent or approval under, any law, governmental rule or regulation or the charter documents, as amended, or bylaws, as amended, of it or any similar instrument binding
on it or any order, writ, injunction or decree of any court or governmental authority against it or by which it or any of its properties is bound or of any indenture, mortgage or contract or other agreement or instrument to which it is a party or by
which it or any of its properties is bound, or constitutes or will constitute a default thereunder or results or will result in the imposition of any lien upon any of its properties; and 

(f) there are no pending or, to its knowledge, threatened actions, suits, investigations or proceedings (whether or not
purportedly on behalf of it) against or affecting it or any of its property before or by any court or administrative agency which, if adversely determined, (i) would adversely affect the ability of it to perform its obligations under this
Agreement or (ii) would call into question or challenge the validity of this Agreement or the enforceability hereof in accordance with the terms hereof, nor is 

  
 -5-

 
the Depositary in default with respect to any order of any court, governmental authority, arbitration board or administrative agency so as to adversely affect its ability to perform its
obligations under this Agreement. 
 SECTION 6. Transfer. Neither party hereto shall be entitled to assign or otherwise
transfer this Agreement (or any interest herein) other than (in the case of the Escrow Agent) to a successor escrow agent under the Escrow and Paying Agent Agreement and other than (in the case of the Depositary) to any entity into which the
Depositary shall merge or with which it shall be consolidated, and any purported assignment in violation thereof shall be void. This Agreement shall be binding upon the parties hereto and their respective successors and (in the case of the Escrow

incurred or sustained by the Escrow Agent as a result of such reliance upon or compliance with such instructions or directions. The Escrow Agent agrees to assume all risks arising out of the use of e-mail to submit instructions and directions to the

 SECTION 9. Obligations Unconditional. The Depositary hereby acknowledges and agrees that its obligation to repay each Deposit together with interest thereon as provided herein is absolute,
irrevocable and unconditional and constitutes a full recourse obligation of the Depositary enforceable against it to the full extent of all of its assets and properties.

Escrow Agent with respect to the subject matter hereof and supersedes all prior and contemporaneous agreements and undertakings, inducements or conditions, express or implied, oral or written.

the Deposits, shall be governed by, and construed in accordance with, the law of the State of New York and subject to the provisions of Regulation D of the Board of Governors of the Federal Reserve System (or any successor), as the same may be
modified and supplemented and in effect from time to time.

such courts.

 SECTION 13. Waiver of Jury Trial Right. EACH OF THE DEPOSITARY AND THE ESCROW AGENT
ACKNOWLEDGES AND ACCEPTS THAT IN ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT SUCH PARTY IRREVOCABLY WAIVES ITS RIGHT TO A TRIAL BY JURY. 
 SECTION 14. Counterparts. This Agreement may be executed in one or more counterparts, all of which taken together shall constitute one instrument. 

SECTION 15. Rights of Receiptholders. The Depositary acknowledges that, if the Depositary shall fail to pay when due hereunder any
interest on the Deposits or the Final Withdrawal, the “Receiptholders” (as defined in the Escrow and Paying Agent Agreement) shall have the right to claim directly against the Depositary and that any such claim shall not be subject to
defenses that the Depositary may have against the Escrow Agent. 
 SECTION 16. Limitation on Damages. In no event shall
the Depositary be responsible or liable for special, indirect, punitive, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit, whether or not foreseeable) suffered by Escrow Agent or any of the
Receiptholders (as defined in the Escrow and Paying Agent Agreement) in connection with this Agreement or the transaction contemplated or any relationships established by this Agreement irrespective of whether the Depositary has been advised of the
likelihood of such loss or damage and regardless of the form of action. In the event of any conflict or inconsistency between any provision in this Agreement and a provision in any other document, the provisions of this Agreement shall control.

 SECTION 17. Miscellaneous. (a) The Depositary shall have only those duties as are specifically and expressly provided
herein and no other duties shall be implied. The Depositary may rely upon and shall not be liable for acting or refraining from acting upon any written notice, document, instruction or request furnished to it hereunder and believed by it to be
genuine and to have been signed or presented by the Escrow Agent without inquiry and without requiring substantiating evidence of any kind. The Depositary shall be under no duty to inquire into or investigate the validity, accuracy or content of any
such document, notice, instruction or request. The Depositary shall have no duty to solicit any payments, including, without limitation, the Deposits. 
 (b) The Depositary shall not be liable for any action taken, suffered or omitted to be taken by it in good faith except to the extent that a final adjudication of a court of competent jurisdiction
determines that the Depositary’s gross negligence or willful misconduct was the primary cause of any loss. The Depositary may execute any of its powers and perform any of its duties hereunder directly or through attorneys, and shall be liable
only for its gross negligence or willful misconduct (as finally adjudicated in a court of competent jurisdiction) in the selection of any such attorney. The Depositary may consult with counsel, accountants and other skilled persons to be selected
and retained by it. The Depositary shall not be liable for any action taken, suffered or omitted to be taken by it in accordance with, or in reliance upon, the advice or opinion of any such counsel, accountants or other skilled persons. In the event
that the Depositary shall be uncertain or believe there is some ambiguity as to its duties or rights hereunder or shall receive instructions, claims or demands from any party hereto which, in its opinion, conflict with any of the provisions of this
Agreement, it shall be entitled to refrain from 

  
 -8-

 
taking any action and its sole obligation shall be to keep safely all property held hereunder until it shall be given a direction in writing by the Escrow Agent which eliminates such ambiguity or
uncertainty to the satisfaction of Depositary or by a final and non-appealable order or judgment of a court of competent jurisdiction. 
 (c) (i) Section 326 of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”) requires the
Depositary to implement reasonable procedures to verify the identity of any person that opens a new account with it. Accordingly, the Escrow Agent acknowledges that Section 326 of the USA PATRIOT Act and the Depositary’s identity
verification procedures require the Depositary to obtain information which may be used to confirm the Escrow Agent’s identity including without limitation name, address and organizational documents (“identifying information”).
The Escrow Agent agrees to provide the Depositary with and consent to the Depositary obtaining from third parties any such identifying information required as a condition of opening an account with or using any service provided by the Depositary.

 (ii) Depositary agrees that upon the reasonable request of the Escrow Agent, it will provide to the Escrow Agent such
information and documents as the Escrow Agent may require (x) to satisfy applicable anti-money laundering laws and regulations, including the USA PATRIOT Act, the regulations administered by the U.S. Department of Treasury’s Office of
Foreign Assets Control (“OFAC”), and other applicable U.S. anti-money laundering laws and regulations (collectively, the “anti-money laundering/OFAC laws”), or (y) to meet the requirements of the Escrow
Agent’s internal know your customer policies and procedures adopted in accordance with the anti-money laundering/OFAC laws. 
 (d) The Escrow Agent has provided the Depositary with its fully executed Internal Revenue Service (“IRS”) Form W-9. The Escrow Agent represents that its correct TIN assigned by the IRS,
or any other taxing authority, is set forth in the delivered form. Any United States federal, state or local income or franchise tax returns required to be filed will, to the greatest extent permitted by applicable law, be prepared and filed by the
Escrow Agent with the IRS and any other taxing authority as required by law. The Escrow Agent acknowledges and agrees that the Depositary shall have no responsibility for the preparation and/or filing of any United States federal, state or local
income, franchise or other tax return with respect to the Deposits or any income earned by the Deposits other than any such responsibility that cannot be assigned to, or assumed by the Escrow Agent under applicable law. 

(e) No party to this Agreement is liable to any other party for losses due to, or if it is unable to perform its obligations under the
terms of this Agreement because of, acts of God, fire, war, terrorism, floods, strikes, electrical outages, equipment or transmission failure, or other causes reasonably beyond its control. If any provision of this Agreement is determined to be
prohibited or unenforceable by reason of any applicable law of a jurisdiction, then such provision shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions
thereof, and any such prohibition or unenforceability in such jurisdiction shall not invalidate or render unenforceable such provisions in any other jurisdiction.

 SECTION 18. Security Procedures. With respect to all funds transfer instructions that
are given pursuant to this Agreement (other than in writing at the time of execution of this Agreement), whether in writing, by facsimile or otherwise, the Depositary is authorized to seek confirmation of such instructions by telephone call-back to
the person or persons designated on Schedule II hereto (“Schedule II”), and the Depositary may rely upon the confirmation of anyone purporting to be the person or persons so designated. Each funds transfer instruction shall be executed by
an authorized signatory, a list of such authorized signatories is set forth on Schedule II. The persons and telephone numbers for call-backs may be changed only in a writing actually received and acknowledged by the Depositary. If the Depositary is
unable to contact any of the authorized representatives identified in Schedule II, the Depositary is hereby authorized to seek confirmation of such instructions by telephone call-back to any one or more of Escrow Agent’s executive officers
(“Executive Officers”), as the case may be, which shall include the titles of Assistant Vice President or Vice President, as the Depositary may select. Such “Executive Officer” shall deliver to the Depositary a fully executed
incumbency certificate, and the Depositary may rely upon the confirmation of anyone purporting to be any such officer. The Depositary and the beneficiary’s bank in any funds transfer may rely solely upon any account numbers or similar
identifying numbers provided by the Escrow Agent to identify (a) the beneficiary, (b) the beneficiary’s bank, or (c) an intermediary bank. The Depositary may apply any of the funds for any payment order it executes using any such
identifying number, even when its use may result in a person other than the beneficiary being paid, or the transfer of funds to a bank other than the beneficiary’s bank or an intermediary bank designated. The Escrow Agent acknowledges that
these security procedures are commercially reasonable. 
 SECTION 19. Head Office Obligations. The Depositary is Natixis
S.A., a French bank (“Natixis”), acting through its New York Branch. The Depositary hereby agrees that, notwithstanding the place of booking or its jurisdiction of incorporation or organization, the obligations of the Depositary
hereunder are also the obligations of the head office of Natixis in Paris, France (the “Head Office”). Accordingly, any beneficiary of this Agreement will be able to proceed directly against the Head Office, if the Depositary
defaults in its obligations to such beneficiary under this Agreement. 
 SECTION 20. Waiver of Immunity. To the extent
that the Depositary or any of its properties has or may hereafter acquire any right of immunity, whether characterized as sovereign immunity or otherwise, and whether under the United States Foreign Sovereign Immunities Act of 1976 (or any successor
legislation) or otherwise, from any legal proceedings, whether in the United States or elsewhere, to enforce or collect upon this Agreement, including, without limitation, immunity from suit or service of process, immunity from jurisdiction or
judgment of any court or tribunal or execution of a judgment, or immunity of any of its property from attachment prior to any entry of judgment, or from attachment in aid of execution upon a judgment, the Depositary hereby irrevocably and expressly
waives any such immunity, and agrees not to assert any such right or claim in any such proceeding, whether in the United States or elsewhere.
