accounts as may be required in connection with the deposits contemplated by

Date.

          (b) The parties hereto further acknowledge and agree that upon any

Exhibit A hereto (a "Notice of Purchase Withdrawal"), request withdrawal of
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, 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.

of the remaining Deposits together with the payment by the Depositary of all
accrued and unpaid interest earned 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 6, 2001 and there are
unwithdrawn Deposits on such date, the Depositary shall pay the amount of the
Final Withdrawal to the Paying Agent on June 27, 2001.

          (ii) The Escrow Agent may, by providing at least 15 days' prior

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.

          (c) If the Depositary receives a duly completed Notice of Purchase
Withdrawal or Notice of Final Withdrawal or Notice of Replacement Withdrawal
(each, a "Withdrawal Notice") complying on their 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. on a Business Day, the Depositary shall make the payments
requested in such Withdrawal Notice no later than 11:00 a.m. 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. on a Business Day, the Depositary shall make the payments requested
in such Withdrawal Notice no later than 11:00 a.m. on the second Business Day
next following such Business Day.

          SECTION 2.4 Other Accounts. On the date of withdrawal of any Deposit
(pursuant to a Notice of Purchase 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 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 27, 2001, 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.

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 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(a) 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))

(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

combination of accounts, right of retention or any similar right (whether
arising under applicable law, contract or otherwise) it may have against the
Deposits howsoever arising. 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 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) pay the full
amount deducted or withheld (including in respect of such additional amounts)
to the relevant taxation authority. 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 5. Representation and Warranties. The Depositary hereby
represents and warrants to ATA, the Escrow Agent, the Pass Through Trustee and

     legal, valid and binding obligations enforceable against it in accordance
     with the terms hereof; and

          (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.

          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 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)

          NOW, THEREFORE, in consideration of the obligations contained

sufficiency of which is hereby acknowledged, the parties hereto hereby agree
as follows:

          SECTION 1. Escrow Agent.

          Section 1.01. Appointment of Escrow Agent. The Initial Purchasers,
for and on behalf of each of the Investors, hereby irrevocably appoint,
authorize and direct the Escrow Agent to act as escrow agent and fiduciary
hereunder and under the Deposit Agreement for such specific purposes and with
such powers as are specifically delegated to the Escrow Agent by the terms of
this Agreement, together with such other powers as are reasonably incidental
thereto. Any and all monies received and held by the Escrow Agent under this
Agreement or the Deposit Agreement shall be held in escrow by the Escrow Agent
in accordance with the terms of this Agreement. This Agreement is irrevocable
and the Investors' rights with respect to any monies received and held in
escrow by the Escrow Agent under this Agreement or the Deposit Agreement shall
only be as provided under the terms and conditions of this Agreement and the
Deposit Agreement. The Escrow Agent (which term as used in this sentence shall
include reference to its affiliates and its own and its affiliates' officers,
directors, employees and agents): (a) shall have no duties or responsibilities
except those expressly set forth in this Agreement and the Deposit Agreement;
(b) shall not be responsible to the Pass Through Trustee or the Investors for
any recitals, statements, representations or warranties of any person other
then itself contained in this Agreement or the Deposit Agreement or for the
failure by the Pass Through Trustee, the Investors, the Paying Agent or any
other person or entity (other than the Escrow Agent) to perform any of its
obligations hereunder (whether or not the Escrow Agent shall have any
knowledge thereof); and (c) shall not be responsible for any action taken or
omitted to be taken by it hereunder or provided for herein or in connection
herewith, except for its own willful misconduct or gross negligence (or simple
negligence in connection with the handling of funds).

          Section 1.02. Instruction; Etc. The Initial Purchasers, for the
benefit of each of the Investors, hereby irrevocably direct the establishment
of an escrow and accordingly instruct the Escrow Agent, and the Escrow Agent
agrees, (a) to enter into the Deposit Agreement and, if requested by the
Company pursuant to Section 4(a)(vii) of the Note Purchase Agreement, to enter

                                                                             4

into a Replacement Deposit Agreement with the Replacement Depositary specified
by the Company, (b) to appoint the Paying Agent as provided for in this
Agreement, (c) upon receipt at any time and from time to time prior to the
Termination Date (as defined below) of a certificate substantially in the form
of Exhibit B hereto (a "Withdrawal Certificate") executed by the Pass Through
Trustee, together with an attached Notice of Purchase Withdrawal in
substantially the form of Exhibit A to the Deposit Agreement duly completed by
the Pass Through Trustee (the "Applicable Notice of Purchase Withdrawal" and
the withdrawal to which it relates, a "Purchase Withdrawal"), immediately to
execute the Applicable Notice of Purchase Withdrawal as Escrow Agent and
transmit it to the Depositary by facsimile transmission in accordance with the
Deposit Agreement; provided that, upon the request of the Pass Through Trustee
after such transmission, the Escrow Agent shall cancel such Applicable Notice
of Purchase Withdrawal, (d) upon receipt of a Withdrawal Certificate executed
by the Pass Through Trustee, together with an attached Notice of Replacement
Withdrawal in substantially the form of Exhibit C to the Deposit Agreement
duly completed by the Pass Through Trustee, to (X) give such Notice of
Replacement Withdrawal to the Depositary requesting a withdrawal, on the date
specified in such notice, which shall not be less than 15 days after such
notice is given (the "Replacement Withdrawal Date"), of all Deposits then held
by the Depositary together with, if the Replacement Withdrawal Date occurs on
a Regular Distribution Date, all accrued and unpaid interest on such Deposits
to but excluding the Replacement Withdrawal Date, and (Y) direct the
Depositary to transfer such Deposits on behalf of the Escrow Agent to the
Replacement Depositary in accordance with the Replacement Deposit Agreement,
and (e) if there are any undrawn Deposits (as defined in the Deposit
Agreement) on the "Termination Date", which shall mean the earlier of (i) May
31, 2001 and (ii) the day on which the Escrow Agent receives notice from the
Pass Through Trustee that the Pass Through Trustee's obligation to purchase
Equipment Notes under the Note Purchase Agreement has terminated, to give
notice to the Depositary (with a copy to the Paying Agent) substantially in
the form of Exhibit B to the Deposit Agreement requesting a withdrawal of all
of the remaining Deposits, together with accrued and unpaid interest on such
Deposits to the date of withdrawal, on the 35th day after the date that such
notice of withdrawal is given to the Depositary (or, if not a Business Day, on
the next succeeding Business Day) (a "Final Withdrawal"), provided that if the
day scheduled for the Final Withdrawal in accordance with the foregoing is
within 10 days before or after a Regular Distribution Date, then the Escrow
Agent shall request that such requested Final Withdrawal be made on such
Regular Distribution Date (the date of such requested withdrawal, the "Final
Withdrawal Date"). If for any reason the Escrow Agent shall have failed to
give the Final Withdrawal Notice to the Depositary on or before June 6, 2001,
and there are unwithdrawn Deposits on such date, the Final Withdrawal Date
shall be deemed to be June 27, 2001.

          Section 1.03. Initial Escrow Amount; Issuance of Escrow Receipts.
The Escrow Agent hereby directs the Initial Purchasers to, and the Initial
Purchasers hereby acknowledge that on the date hereof they shall, irrevocably
deliver by wire transfer to the Depositary on behalf of the Escrow Agent, an
amount in U.S. dollars ("Dollars") and immediately available funds equal to
$201,901,000 for deposit on behalf of the Escrow Agent with the Depositary in
accordance with Section 2.1 of the Deposit Agreement. The Initial Purchasers
hereby instruct the Escrow Agent, upon receipt of such sum from the Initial
Purchasers, to confirm such receipt by executing and delivering to the Pass
Through Trustee an Escrow Receipt in the form of Exhibit A hereto (an "Escrow
Receipt"), (a) to be affixed by the Pass Through Trustee to each Certificate
and (b) to evidence the same percentage interest (the "Escrow Interest") in
the Account Amounts (as defined in Section 1.04) as the Fractional Undivided
Interest in the Pass Through Trust evidenced

<PAGE>

                                                                             5

by the Certificate to which it is to be affixed. The Escrow Agent shall
provide to the Pass Through Trustee for attachment to each Certificate newly
issued under and in accordance with the Pass Through Trust Agreement an
executed Escrow Receipt as the Pass Through Trustee may from time to time
request of the Escrow Agent. Each Escrow Receipt shall be registered by the
Escrow Agent in a register (the "Register") maintained by the Escrow Agent in
the same name and same manner as the Certificate to which it is attached and
may not thereafter be detached from such Certificate to which it is to be
affixed prior to the distribution of the Final Withdrawal (the "Final
Distribution"). After the Final Distribution, no Escrow Receipts shall be
issued and the Pass Through Trustee shall request the return to the Escrow
Agent for cancellation of all outstanding Escrow Receipts.

          Section 1.04. Payments to Receiptholders. All payments and
distributions made to holders of an Escrow Receipt (collectively
"Receiptholders") in respect of the Escrow Receipt shall be made only from
amounts deposited in the Paying Agent Account ("Account Amounts"). Each
Receiptholder, by its acceptance of an Escrow Receipt, agrees that (a) it will
look solely to the Account Amounts for any payment or distribution due to such
Receiptholder pursuant to the terms of the Escrow Receipt and this Agreement
and (b) it will have no recourse to ATA, the Pass Through Trustee, the Paying
Agent, the Escrow Agent or Wilmington Trust Company, except as expressly
provided herein or in the Pass Through Trust Agreement. No Receiptholder shall
have any right to vote or in any manner otherwise control the operation and
management of the Paying Agent Account or the obligations of the parties
hereto, nor shall anything set forth herein, or contained in the terms of the
Escrow Receipt, be construed so as to constitute the Receiptholders from time
to time as partners or members of an association.

          Section 1.05. Mutilated, Destroyed, Lost or Stolen Escrow Receipt.
If (a) any mutilated Escrow Receipt is surrendered to the Escrow Agent or the
Escrow Agent receives evidence to its satisfaction of the destruction, loss or
theft of any Escrow Receipt and (b) there is delivered to the Escrow Agent and
the Pass Through Trustee such security, indemnity or bond, as may be required
by them to hold each of them harmless, then, absent notice to the Escrow Agent
or the Pass Through Trustee that such destroyed, lost or stolen Escrow Receipt
has been acquired by a bona fide purchaser, and provided that the requirements
of Section 8-405 of the Uniform Commercial Code in effect in any applicable
jurisdiction are met, the Escrow Agent shall execute, authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts and of like
Escrow Interest in the Account Amounts and bearing a number not
contemporaneously outstanding.

          In connection with the issuance of any new Escrow Receipt under this
Section 1.05, the Escrow Agent may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Pass
Through Trustee and the Escrow Agent) connected therewith.

          Any duplicate Escrow Receipt issued pursuant to this Section 1.05
shall constitute conclusive evidence of the appropriate Escrow Interest in the
Account Amounts, as if originally issued, whether or not the lost, stolen or
destroyed Escrow Receipt shall be found at any time.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Escrow
Receipts.

          Section 1.06. Additional Escrow Amounts. On the date of any Purchase
Withdrawal, the Pass Through Trustee may re-deposit with the Depositary some
or all of the amounts so withdrawn in accordance with Section 2.4 of the
Deposit Agreement.

          Section 1.07. Resignation or Removal of Escrow Agent. Subject to the
appointment and acceptance of a successor Escrow Agent as provided below, the
Escrow Agent may resign at any time by giving 30 days' prior written notice
thereof to the Investors, but may not otherwise be removed except for cause by
the written consent of the Investors with respect to Investors representing
Escrow Interests aggregating not less than a majority in interest in the
Account Amounts (an "Action of Investors"). Upon any such resignation or
removal, the Investors, by an Action of Investors, shall have the right to
appoint a successor Escrow Agent. If no successor Escrow Agent shall have been
so appointed and shall have accepted such appointment within 30 days after the
retiring Escrow Agent's giving of notice of resignation or the removal of the
retiring Escrow Agent, then the retiring Escrow Agent may appoint a successor
Escrow Agent, which shall be a commercial bank which has an office in the
United States with a combined capital and surplus of at least $100,000,000.
Upon the acceptance of any appointment as Escrow Agent hereunder by a
successor Escrow Agent, such successor Escrow Agent shall enter into such
documents as the Pass Through Trustee shall require and shall thereupon
succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be
discharged from its duties and obligations hereunder. No resignation or
removal of the Escrow Agent shall be effective unless a written confirmation
shall have been obtained from each of Moody's Investors Service, Inc. and
Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies,
Inc., that the replacement of the Escrow Agent with the successor Escrow Agent
will not result in (a) a reduction of the rating for the Certificates below
the then current rating for the Certificates or (b) a withdrawal or suspension
of the rating of the Certificates.

          Section 1.08. Persons Deemed Owners. Prior to due presentment of a
Certificate for registration of transfer, the Escrow Agent and the Paying
Agent may treat the Person in whose name any Escrow Receipt is registered (as
of the day of determination) as the owner of such Escrow Receipt for the
purpose of receiving distributions pursuant to this Agreement and for all
other purposes whatsoever, and none of the Escrow Agent or the Paying Agent
shall be affected by any notice to the contrary.

          Section 1.09. Further Assurances. The Escrow Agent agrees to take
such actions, and execute such other documents, as may be reasonably requested
by the Pass Through Trustee in order to effectuate the purposes of this
Agreement and the performance by the Escrow Agent of its obligations
hereunder.

          SECTION 2. Paying Agent.

          Section 2.01. Appointment of Paying Agent. The Escrow Agent hereby
irrevocably appoints and authorizes the Paying Agent to act as its paying
agent hereunder, for the benefit of the Investors, for such specific purposes
and with such powers as are specifically delegated to the Paying Agent by the
terms of this Agreement, together with such other powers as are reasonably
incidental thereto. Any and all money received and held by the Paying Agent
under this Agreement or the Deposit Agreement shall be held in the Paying
Agent Account (as defined below) for the benefit of the Investors. The Paying
Agent (which term as used in this

                                                                             7

sentence shall include reference to its affiliates and its own and its
affiliates' officers, directors, employees and agents): (a) shall have no
duties or responsibilities except those expressly set forth in this Agreement,
and shall not by reason of this Agreement be a trustee for the Escrow Agent;
(b) shall not be responsible to the Escrow Agent for any recitals, statements,
representations or warranties of any person other then itself contained in
this Agreement or for the failure by the Escrow Agent or any other person or
entity (other than the Paying Agent) to perform any of its obligations
hereunder (whether or not the Paying Agent shall have any knowledge thereof);
and (c) except in respect of its express obligations hereunder, shall not be
responsible for any action taken or omitted to be taken by it hereunder or
provided for herein or in connection herewith, except for its own willful
misconduct or gross negligence (or simple negligence in connection with the
handling of funds).

          Section 2.02. Establishment of Paying Agent Account. The Paying
Agent shall establish a deposit account (the "Paying Agent Account") at
Wilmington Trust Company in the name of the Escrow Agent. It is expressly
understood by the parties hereto that the Paying Agent is acting as the paying
agent of the Escrow Agent hereunder and that no amounts on deposit in the
Paying Agent Account constitute part of the Trust Property.

          Section 2.03. Payments from Paying Agent Account. The Escrow Agent
hereby irrevocably instructs the Paying Agent, and the Paying Agent agrees to
act, as follows:

          (a) On each Interest Payment Date (as defined in the Deposit
Agreement) or as soon thereafter as the Paying Agent has confirmed receipt in
the Paying Agent Account from the Depositary of any amount in respect of
accrued interest on the Deposits, the Paying Agent shall distribute out of the
Paying Agent Account the entire amount deposited therein by the Depositary.
There shall be so distributed to each Receiptholder of record on the 15th day
(whether or not a Business Day) preceding such Interest Payment Date by check
mailed to such Receiptholder, at the address appearing in the Register, such
Receiptholder's pro rata share (based on the Escrow Interest in the Account
Amounts held by such Receiptholder) of the total amount of interest deposited
by the Depositary in the Paying Agent Account on such date, except that, with
respect to Escrow Receipts registered on the Record Date in the name of The
Depository Trust Company ("DTC"), such distribution shall be made by wire
transfer in immediately available funds to the account designated by DTC.

          (b) Upon the confirmation by the Paying Agent of receipt in the
Paying Agent Account from the Depositary of any amount in respect of the Final
Withdrawal, the Paying Agent shall forthwith distribute the entire amount of
the Final Withdrawal deposited therein by the Depositary to each Receiptholder
of record on the 15th day (whether or not a Business Day) preceding the Final
Withdrawal Date by check mailed to such Receiptholder, at the address
appearing in the Register, such Receiptholder's pro rata share (based on the
Escrow Interest in the Account Amounts held by such Receiptholder) of the
total amount in the Paying Agent Account on account of such Final Withdrawal,
except that, with respect to Escrow Receipts registered on such record date in
the name of DTC, such distribution shall be made by wire transfer in
immediately available funds to the account designated by DTC.

          (c) If any payment of interest or principal in respect of the Final
Withdrawal is not received by the Paying Agent within five days of the
applicable date when due, then it shall

<PAGE>

                                                                             8

be distributed to Receiptholders after actual receipt by the Paying Agent on
the same basis as a Special Payment is distributed under the Pass Through
Trust Agreement.

          (d) The Paying Agent shall include with any check mailed pursuant to
this Section any notice required to be distributed under the Pass Through
Trust Agreement that is furnished to the Paying Agent by the Pass Through
Trustee.

          Section 2.04. Withholding Taxes. The Paying Agent shall exclude and
withhold from each distribution of accrued interest on the Deposits (as
defined in the Deposit Agreement) and any amount in respect of the Final
Withdrawal any and all withholding taxes applicable thereto as required by
federal law of the United States. The Paying Agent agrees to act as such
withholding agent and, in connection therewith, whenever any present or future
taxes or similar charges are required to be withheld with respect to any
amounts payable in respect of the Deposits (as defined in the Deposit
Agreement) or the escrow amounts, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the
Receiptholders, that it will file any necessary withholding tax returns or
statements when due, and that, as promptly as possible after the payment
thereof, it will deliver to each such Receiptholder appropriate documentation
showing the payment thereof, together with such additional documentary
evidence as such Receiptholder may reasonably request from time to time. The
Paying Agent agrees to file any other information reports as it may be
required to file under United States law. Each Receiptholder or beneficial
owner of an interest in an Escrow Receipt that is a Non-U.S. Person, by its
acceptance of an Escrow Receipt or a beneficial interest therein, agrees to
indemnify and hold harmless the Escrow Agent and the Paying Agent from and
against any improper failure to withhold Taxes from amounts payable to it or
for its benefit other than an improper failure attributable to the gross
negligence or willful misconduct of the Escrow Agent or the Paying Agent, as
the case may be. The Paying Agent agrees, to the extent required by the
Internal Revenue Code of 1986, as amended (the "Code"), and applicable federal
regulations thereunder, to withhold from each payment due hereunder or under
any Escrow Receipts, United States withholding taxes at the appropriate rate,
and, on a timely basis, to deposit such amounts with an authorized depository
and make such returns, filings and other reports in connection therewith as
are required by the Code. In the event that any withholding tax is imposed on
a payment to a Receiptholder, such tax shall reduce the amount otherwise
distributable to the Receiptholder in accordance with this Section. Any
Receiptholder which is organized under the laws of a jurisdiction outside the
United States shall, on or prior to the date such Receiptholder becomes a
Receiptholder, (a) so notify the Paying Agent, (b) (i) provide the Paying
Agent with Internal Revenue Service form W-8BEN or W-8ECI, as appropriate, or
(ii) notify the Paying Agent that it is not entitled to an exemption from
United States withholding tax or a reduction in the rate thereof on payments
of interest. Any such Receiptholder agrees by its acceptance of a Escrow
Receipt, on an ongoing basis, to provide like certification for each taxable
year and to notify the Paying Agent should subsequent circumstances arise
affecting the information provided the Paying Agent in clauses (a) and (b)
above. The Paying Agent shall be fully protected in relying upon, and each
Receiptholder by its acceptance of an Escrow Receipt agrees to indemnify and
hold the Paying Agent harmless against all claims or liability of any kind
arising in connection with or related to the Paying Agent's reliance upon any
documents, forms or information provided by any Receiptholder to the Paying
Agent. In addition, if the Paying Agent has not withheld taxes on any payment
made to any Receiptholder, and the Paying Agent is subsequently required to
remit to any taxing authority any such amount not withheld, such Receiptholder
shall return such amount to the Paying Agent upon written demand by the Paying

<PAGE>

                                                                             9

Agent. The Paying Agent shall be liable only for direct (but not
consequential) damages to any Receiptholder due to the Paying Agent's
violation of the Code and only to the extent such liability is caused by the
Paying Agent's gross negligence or willful misconduct.

          Section 2.05. Resignation or Removal of Paying Agent. Subject to the
appointment and acceptance of a successor Paying Agent as provided below, the
Paying Agent may resign at any time by giving 30 days' prior written notice
thereof to the Escrow Agent, but may not otherwise be removed except for cause
by the Escrow Agent. Upon any such resignation or removal, the Escrow Agent
shall have the right to appoint a successor Paying Agent. If no successor
Paying Agent shall have been so appointed and shall have accepted such
appointment within 30 days after the retiring Paying Agent's giving of notice
of resignation or the removal of the retiring Paying Agent, then the retiring
Paying Agent may (i) appoint a successor Paying Agent, which shall be a
commercial bank which has an office in the United States with a combined
capital and surplus of at least $100,000,000 or (ii) petition a court of
competent jurisdiction to appoint a successor. Upon the acceptance of any
appointment as Paying Agent hereunder by a successor Paying Agent, such
successor Paying Agent shall enter into such documents as the Escrow Agent
shall require and shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Paying Agent, and the
retiring Paying Agent shall be discharged from its duties and obligations
hereunder.

          Section 2.06. Notice of Final Withdrawal. Promptly after receipt by
the Paying Agent of notice that the Escrow Agent has requested a Final
Withdrawal or that a Final Withdrawal will be made, the Paying Agent shall
cause notice of the distribution of the Final Withdrawal to be mailed to each
of the Receiptholders at its address as it appears in the Register. Such
notice shall be mailed not less than 20 days prior to the Final Withdrawal
Date. Such notice shall set forth:

               (i) the Final Withdrawal Date and the date for determining
          Receiptholders of record who shall be entitled to receive
          distributions in respect of the Final Withdrawal,

               (ii) the amount of the payment in respect of the Final
          Withdrawal for each $1,000 face amount Certificate (based on
          information provided by the Pass Through Trustee) and the amount
          thereof constituting unused Deposits (as defined in the Deposit
          Agreement) and interest thereon, and

               (iii) if the Final Withdrawal Date is the same date as a
          Regular Distribution Date, the total amount to be received on such
          date for each $1,000 face amount Certificate (based on information
          provided by the Pass Through Trustee).

          Such mailing may include any notice required to be given to
Certificateholders in connection with such distribution pursuant to the Pass
Through Trust Agreement.

          SECTION 3. Payments. If, notwithstanding the instructions in Section
4 of the Deposit Agreement that all amounts payable to the Escrow Agent under
the Deposit Agreement be paid by the Depositary directly to the Paying Agent
or the Pass Through Trustee (depending on the circumstances), the Escrow Agent
receives any payment thereunder, then the Escrow Agent shall forthwith pay
such amount in Dollars and in immediately available funds by wire transfer to
(a) in the

<PAGE>

                                                                            10

case of a payment of accrued interest on the Deposits (as defined in the
Deposit Agreement) or any Final Withdrawal, directly to the Paying Agent
Account and (b) in the case of any Purchase Withdrawal, directly to the Pass
Through Trustee or its designee as specified and in the manner provided in the
Applicable Notice of Purchase Withdrawal and (c) in the case of any
Replacement Withdrawal (other than accrued interest), to the Replacement
Depositary as provided in the Replacement Depositary Agreement. The Escrow
Agent hereby waives any and all rights of set-off, combination of accounts,
right of retention or any similar right (whether arising under applicable law,
contract or otherwise) it may have against amounts payable to the Paying Agent
howsoever arising.

          SECTION 4. Other Actions. The Escrow Agent shall take such other
actions under or in respect of the Deposit Agreement (including, without
limitation, the enforcement of the obligations of the Depositary thereunder)
as the Investors, by an Action of Investors, may from time to time request.

          SECTION 5. Representations and Warranties of the Escrow Agent. The
Escrow Agent represents and warrants to ATA, the Investors, the Paying Agent
and the Pass Through Trustee as follows:

          (i)  it is a national banking association duly organized and validly

               its property before or by any court or administrative agency
               which, if adversely determined, (A) would adversely affect the
               ability of it to perform its obligations under this Agreement
               or the Deposit Agreement or any Replacement Deposit Agreement
               or (B) would call into question or challenge the validity of

               its property before or by any court or administrative agency
               which, if adversely determined, (A) would adversely affect the
               ability of it to perform its obligations under this Agreement

               this Agreement or the enforceability hereof in accordance with
               the terms hereof, nor is the Paying Agent in default with
               respect to any order of any court, governmental authority,

failing or refusing to act hereunder unless it shall have been indemnified by
the party requesting such action in a manner reasonably satisfactory to it

          This Escrow Receipt evidences a fractional undivided interest in
amounts ("Account Amounts") from time to time deposited into a certain paying
agent account (the "Paying Agent Account") described in the Escrow and Paying
Agent Agreement (Class G) dated as of February 15, 2000 (as amended, modified
or supplemented from time to time, the "Escrow and Paying Agent Agreement")
among First Security Bank, National Association, as Escrow Agent (in such
capacity, together with its successors in such capacity, the "Escrow Agent"),
Salomon Brothers Inc, Morgan Stanley & Co. Incorporated, Chase Securities
Inc., and Banc One Capital Markets, Inc., as Initial Purchasers, Wilmington
Trust Company, as Pass Through Trustee (in such capacity, together with its
successors in such capacity, the "Pass Through Trustee") and Wilmington Trust
Company, as paying agent (in such capacity, together with its successors in
such capacity, the "Paying Agent"). Capitalized terms not defined herein shall
have the meanings assigned to them in the Escrow and Paying Agent Agreement.

          This Escrow Receipt is issued under and is subject to the terms,
provisions and conditions of the Escrow and Paying Agent Agreement. By virtue
of its acceptance hereof the holder of this Escrow Receipt assents and agrees
to be bound by the provisions of the Escrow and Paying Agent Agreement and
this Escrow Receipt.

          This Escrow Receipt represents a fractional undivided interest in
amounts deposited from time to time in the Paying Agent Account, and grants or
represents no rights, benefits or interests of any kind in respect of any
assets or property other than such amounts. This Escrow Receipt evidences the
same percentage interest in the Account Amounts as the Fractional Undivided
Interest in the Pass Through Trust evidenced by the Certificate to which this
Escrow Receipt is affixed.

          All payments and distributions made to Receiptholders in respect of
the Escrow Receipt shall be made only from Account Amounts deposited in the

this Escrow Receipt, agrees that it will look solely to the Account Amounts
for any payment or distribution due to it pursuant to this Escrow Receipt and
that it will not have any recourse to ATA, the Pass Through Trustee, the
Paying Agent or the Escrow Agent, except as expressly provided herein or in
the Pass Through Trust Agreement. No Receiptholder of this Escrow Receipt
shall have any right to vote or in any manner otherwise control the operation
and management of the Paying Agent Account, nor shall anything set forth
herein, or contained in the terms of this Escrow Receipt, be construed so as
to constitute the Receiptholders from time to time as partners or members of
an association.

          This Escrow Receipt may not be assigned or transferred except in
connection with the assignment or transfer of the Certificate to which this
Escrow Receipt is affixed. After payment to the holder hereof of its Escrow
Interest in the Final Distribution, upon the request of

the Pass Through Trustee, the holder hereof will return this Escrow Receipt to
the Pass Through Trustee.

          The Paying Agent may treat the person in whose name the Certificate
to which this Escrow Receipt is attached as the owner hereof for all purposes,

          THIS ESCROW RECEIPT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAW OF THE STATE OF NEW YORK.
