Following such withdrawal the balance in the related Account shall be zero and the Depositary shall close such Account.

If a Notice of Final Withdrawal has not been given to the Depositary on or before September 29, 2002 and there are unwithdrawn Deposits on such date, the Depositary shall pay the amount of the Final Withdrawal to the Paying Agent on October 14, 2002. 4 (ii) The Escrow Agent may, by providing at least 15 days' prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a "Notice of Replacement Withdrawal"), request withdrawal of the entire amount of all Deposits then held by the Depositary together with, if the Replacement Withdrawal occurs on an Interest Payment Date, the payment by the Depositary of all accrued and unpaid interest on such Deposits to but excluding the specified date of withdrawal (a "Replacement Withdrawal"), on such date as shall be specified in such Notice of Replacement Withdrawal. (iii) The Escrow Agent may, by providing at least 15 days' prior notice of withdrawal to the Depositary in the form of Exhibit D hereto (a "Notice of Prepayment Withdrawal"), withdraw all or a portion of the Deposit together with all accrued and unpaid interest thereon to but excluding the specified date of withdrawal (a "Prepayment Withdrawal"), on such date as shall be specified in such Notice of Prepayment Withdrawal. Following such withdrawal the balance in the Account shall be reduced by the amount of the withdrawal. Upon any Prepayment Withdrawal, the Depositary shall pay to the Paying Agent the amount requested in the related Notice of Prepayment Withdrawal. (c) If the Depositary receives a duly completed Notice of Purchase Withdrawal, Notice of Prepayment Withdrawal, Notice of Final Withdrawal or Notice of Replacement Withdrawal (each, a "Withdrawal Notice") complying on its face 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 3:00 p.m. (New York City time) on a Business Day, the Depositary shall make the payments requested in such Withdrawal Notice no later than 11:00 a.m. (New York City time) on the next succeeding Business Day or such later day specified in such Withdrawal Notice, and if such complying Withdrawal Notice is received by the Depositary after 3:00 p.m. (New York City time) on a Business Day, the Depositary shall make the payments requested in such Withdrawal Notice no later than 11:00 a.m. (New York time) on the second Business Day next following such Business Day or such later date specified in such Withdrawal Notice.

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 the date set forth in Schedule I hereto, and bear interest as provided in Section 2.2. 5 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. (a) 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 any portion thereof being made and (ii) all accrued and unpaid interest earned 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. (b) For the avoidance of doubt, the obligations of the Depositary under the last two sentences of Section 2.2 hereof shall remain in full force and effect notwithstanding the execution and delivery of a Replacement Deposit Agreement in accordance with Section 4(a)(vii) of the Note Purchase Agreement. SECTION 4. Payments. All payments (including, without limitation, those payments made in respect of Taxes (as defined and provided for below)) made by the Depositary hereunder shall be paid in United States Dollars and in immediately available funds by wire transfer (i) in the case of accrued interest on the Deposits payable under Section 2.2 hereof, any Prepayment Withdrawal or any Final Withdrawal, directly to the Paying Agent at Wilmington Trust Company, Wilmington, DE, ABA # 031-100-092, Account No. 57831-0, Attention: Jeanne Oller, Reference: American Trans Air 2002-1B, 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.

Except as provided below, all payments on or in respect of each Deposit shall be made by the Depositary 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 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, (ii) pay the full amount deducted or withheld (including in respect of such additional amounts) to the relevant taxation authority and (iii) if the Taxes required to be deducted or withheld are imposed by the Republic of Italy or any political subdivision thereof, 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 6 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 5. Representation and Warranties.
