 NOW, THEREFORE, in consideration of the obligations contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which is 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 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. It is the express intention of the parties hereto that all amounts on deposit hereunder be deemed
to be general deposits, not special deposits, and that such deposits create a customer and bank relationship between the Escrow Agent and Depository. 
 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 the account of JPMorgan Chase Bank, N.A., ABA: 021000021, Account Number: 9009000150, Account Name: PTFS, Account Number: E01053 for further credit to Wilmington Trust Company, ref: United EETC 2009-2A-O, and the Depositary shall
accept from the Underwriters, on behalf of the Escrow Agent, the sum of US$697,731,000. Upon acceptance of such sum, the Depositary shall (i) establish each of the deposits specified in Schedule I hereto maturing on February 22, 2010
(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 9.75% 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 in
arrears on July 15, 2010 and on the date of the Final Withdrawal (as defined below), if any, or the date of the Replacement Withdrawal (as defined below), as applicable, all in accordance with the terms of this Agreement. Interest accrued on
any Deposit that is withdrawn pursuant to a Notice of Financing Withdrawal (as defined below) shall be paid on July 15, 2010, notwithstanding any intervening Final Withdrawal (as defined below).

 [Deposit Agreement (Class A)] 
  

 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 two Business Days’ prior notice of withdrawal to the Depositary in the form of Exhibit A hereto (a “Notice of Financing 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 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, Chicago, Illinois 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 United, 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 February 7, 2010 and there are
unwithdrawn Deposits on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on February 22, 2010. 
 (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 Financing 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 Financing Withdrawal or 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. 
 If such complying Withdrawal Notice is received by the Depositary no later than 11:00 a.m. (New York City time) on a Business Day, the Depositary shall make the payments requested in such Withdrawal
Notice no later than 10:00 a.m. (New York City time) on the next succeeding Business Day or such later time as requested by the Escrow Agent while funds may be transferred in the Fed Wire electronic transfer system as specified in such
Withdrawal Notice. If such complying Withdrawal Notice is received by the Depositary after 11:00 a.m. (New York City time) on a Business Day, the Depositary shall make the payments requested in such Withdrawal Notice no later than
10:00 a.m. (New York City time) on the second Business Day next following such Business Day or such later time as requested by the Escrow Agent while funds may be transferred in the Fed Wire electronic transfer system as specified in such
Withdrawal Notice.

 Section 2.4 Other Accounts. On the date of withdrawal of any Deposit pursuant to
a Notice of Financing Withdrawal, the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow Agent, shall be entitled to re-deposit with the Depositary any 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) interest on the amount so re-deposited shall be calculated as if such amount had been on Deposit under this Agreement at all times from the Deposit Date until the date of such re-deposit, and thereafter shall bear interest as provided in
Section 2.1. The Escrow Agent shall provide the Depositary with notice of the re-deposit at least two Business Days prior to such re-deposit and 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 of such funds 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, Delaware, ABA#031100092, Account No. 094945-000, Attention: Steve Barone,
Telephone No. (302) 636-6973, Reference: United 2009-2, 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 Financing 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 Financing 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.
Except as expressly provided below, 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 such deductions or withholding and (ii) timely pay to the appropriate authority the full amount deducted or withheld and timely file all
reports and returns relating to such deductions or withholding and payment thereof in accordance with applicable law. 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 extension.

 Section 16. Limitation on Damages.
 Section 16.1 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

 [Deposit Agreement (Class A)] 
  

 
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 except as provided in Section 17 below. The Depositary shall have no duty to solicit any payments including, without limitation, the Deposits. 
 Section 16.2 The Depositary shall not be liable for any action taken, suffered or omitted to be taken by it 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 agents or 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 agent or 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 taking any action and its sole obligation shall be to keep safely all property held in escrow 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. The Escrow Agent agrees to pursue any
redress or recourse in connection with any dispute without making the Depositary a party to the same. 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. Anything in this Agreement to the contrary notwithstanding, in no event shall the Depositary be responsible or liable for special, incidental, punitive, indirect or consequential loss or damage of any kind whatsoever
(including, but not limited to, loss of profit, whether or not foreseeable) irrespective of whether the Depositary has been advised of the likelihood of such loss or damage and regardless of the form of action. 
 Section 16.3 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 Parties acknowledge 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 Parties identity including without limitation name, address and organizational documents
(“identifying information”). The Parties agree 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

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 or 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 invalidiate or render unenforceable such provisions in any other jurisdiction. 
 Section 17. 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 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 the 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 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 escrowed 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 designated intermediary bank, as applicable. The Escrow Agent
acknowledges that these security procedures are commercially reasonable.

 W I T N E S S E T H: 
 WHEREAS, United Air Lines, Inc. (“United”) 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 November 24, 2009, the “Trust Supplement”) Pass Through Trust
Agreement dated as of June 26, 2007 (as amended, modified or supplemented from time to time in accordance with the terms thereof, the “Pass Through Trust Agreement”) relating to United Air Lines Pass Through Trust 2009-2B-O
pursuant to which the United Air Lines Pass Through Trust, Series 2009-2B-O Certificates referred to therein (the “Certificates”) are being issued (the date of such issuance, the “Issuance Date”); 
 WHEREAS, United and Morgan Stanley & Co., Incorporated, J.P. Morgan Securities 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

 [Deposit Agreement (Class B)] 
  
 NOW, THEREFORE, in consideration of the obligations contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which is 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 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. It is the express intention of the parties hereto that all amounts on deposit hereunder be deemed to be general deposits, not special deposits, and that such
deposits create a customer and bank relationship between the Escrow Agent and Depository. 
 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 the account of JPMorgan Chase Bank, N.A., ABA: 021000021,
Account Number: 9009000150, Account Name: PTFS, Account Number: E01054 for further credit to Wilmington Trust Company, ref: United EETC 2009-2B-O, and the Depositary shall accept from the Underwriters, on behalf of the Escrow Agent, the sum of
US$112,606,000. Upon acceptance of such sum, the Depositary shall (i) establish each of the deposits specified in Schedule I hereto maturing on February 22, 2010 (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 12.000% 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 in arrears on July 15, 2010 and on the date of the Final Withdrawal (as
defined below), if any, or the date of the Replacement Withdrawal (as defined below), as applicable, all in accordance with the terms of this Agreement. Interest accrued on any Deposit that is withdrawn pursuant to a Notice of Financing Withdrawal
(as defined below) shall be paid on July 15, 2010, 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 two Business Days’ prior notice of withdrawal to the Depositary in the form
of Exhibit A hereto (a “Notice of 
  

 2 

 [Deposit Agreement (Class B)] 
  
 Financing 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 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, Chicago, Illinois 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
United, 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 February 7, 2010 and there are unwithdrawn Deposits on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on
February 22, 2010. 
 (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 Financing 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 Financing Withdrawal or 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.

 If such complying Withdrawal Notice is received by the Depositary no later than 11:00 a.m. (New York City time) on a
Business Day, the Depositary shall make the payments requested in such Withdrawal Notice no later than 10:00 a.m. (New York City time) on the next succeeding Business Day or such later time as requested by the Escrow Agent while funds may be
transferred in the Fed Wire electronic transfer system as specified in such Withdrawal Notice. If such complying Withdrawal Notice is received by the Depositary after 11:00 a.m. (New York City time) on a Business Day, the Depositary shall make
the payments requested in such Withdrawal Notice no later than 10:00 a.m. (New York City time) on the second Business Day next following such Business Day or such later time as requested by the Escrow Agent while funds may be transferred in the
Fed Wire electronic transfer system as specified in such Withdrawal Notice.

 [Deposit Agreement (Class B)] 
  
 Section 2.4 Other Accounts. On the date of withdrawal of any Deposit pursuant to a Notice of Financing
Withdrawal, the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow Agent, shall be entitled to re-deposit with the Depositary any 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) interest on the amount so
re-deposited shall be calculated as if such amount had been on Deposit under this Agreement at all times from the Deposit Date until the date of such re-deposit, and thereafter shall bear interest as provided in Section 2.1. The Escrow Agent
shall provide the Depositary with notice of the re-deposit at least two Business Days prior to such re-deposit and 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 of such funds 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, Delaware, ABA#031100092, Account No. 094946-000, Attention: Steve Barone, Telephone No. (302) 636-6973,
Reference: United 2009-2, 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
Financing 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 Financing 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. Except as expressly provided
below, 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 such deductions or withholding and (ii) timely pay to the appropriate authority the full amount deducted or withheld and timely file all reports and returns relating to such deductions
or withholding and payment thereof in accordance with applicable law. 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 extension. 
  

 4 

 [Deposit Agreement (Class B)] 
  
 Section 5. Representation and Warranties. The Depositary hereby represents and warrants to

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

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 any purported assignment in violation thereof shall be void. This Agreement shall be

 [Deposit Agreement (Class B)] 
  
 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 laws 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. 
 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.
 Section 16.1 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 
  

 7 

 [Deposit Agreement (Class B)] 
  
 duty to inquire into or investigate the validity, accuracy or content of any such document, notice, instruction or request
except as provided in Section 17 below. The Depositary shall have no duty to solicit any payments including, without limitation, the Deposits. 
 Section 16.2 The Depositary shall not be liable for any action taken, suffered or omitted to be taken by it 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 agents or 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 agent or 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 taking any action and its sole obligation shall be to keep safely all property held in escrow 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. The Escrow Agent agrees to pursue any redress or recourse in connection with any dispute without

acknowledges that these security procedures are commercially reasonable.
