                                  THE CREDIT

          2.01 Revolving Credit Loans.

               (a) Each Bank severally agrees, subject to the terms and
conditions of this Agreement, to make available to the Borrower, for the
purposes set forth in Section 6.01, Revolving Credit Loans and to participate
in Letter of Credit Advances to the Borrower which in an aggregate amount do
not exceed the Commitment of each Bank, provided, however, that the sum of the
aggregate amount of the Revolving Credit Loans and the maximum amount
available to be drawn on all outstanding Letters of Credit shall not exceed
the lesser of the Borrowing Base (as the Borrowing Base is reduced pursuant to
Section 2.05 or otherwise) or the Commitments; provided, however, that the
aggregate amount of Letter of Credit Advances (including, without limitation,
the Letter of Credit Advances cash collateralized pursuant to Section 3.04
hereof) outstanding at any time shall not exceed Twenty-Five Million and
00/100 Dollars ($25,000,000). Notwithstanding anything herein to the contrary,
the Borrower may not obtain any Advance or Letter of Credit Advance on the
last day of any calendar quarter.

               (b) Advances made pursuant to this Section 2.01 shall
constitute revolving credit, subject to the provisions of Section 2.10 hereof,
and prior to the Termination Date Borrower may borrow, repay and reborrow
Revolving Credit Loans.

               (c) For the purpose of this Agreement, the value of Aviation
Property shall be based on the Appraisal Report of Aviation Property by Avmark
dated November 15, 1994. Such value shall be adjusted on a semi-annual basis
on each Adjustment Date based on Avmark's most recently published values of
L-1011-50 aircraft by the same percentage change in the base values of such
L-1011-50 aircraft which have occurred since the Avmark publication of
November 15, 1994 through January, 1997. Within 120 days after the Closing
Date, the Agent will be having an appraisal of the Aviation Property by an
independent third party appraiser acceptable to the Required Banks and at the
expense of the Borrower, and the value of the Aviation Property shall be
adjusted as determined by the Agent based on the results of such appraisals.
Upon the acquisition of any aircraft or engines by the Borrower which are to
be subject to the Security Agreement and part of the Aviation Property, the
Agent may require an appraisal of such new Aviation Property by an independent
third party appraiser acceptable to the Required Banks and at the expense of
the Borrower, and the value of such new Aviation Property for the Borrowing
Base shall be based on the results of such appraisals. Additionally, if
required by the Required Banks, 90 days after each Adjustment Date the
Required Banks may request an appraisal of the Aviation Property by an
independent third party appraiser acceptable to the Required Banks and at the
expense of the Borrower and the value of the Aviation Property shall also be
adjusted based on the results of such appraisals. In the event that the
aggregate Commitments become greater than the Borrowing Base determined by the
method described in the first sentence of this clause (c) and the Required
Banks have not requested an appraisal pursuant to the immediately preceding
sentence, Borrower may, at its own expense, have the Aviation Property
physically appraised by Avmark, or any other independent third party appraiser
acceptable to the Required Banks, within the thirty (30) day period following
an Adjustment Date to establish the value of Aviation Property and the value
of the Aviation Property shall be based on the results of such appraisals. If
acceptable to the Required Banks in their sole discretion, an appraisal report
from an independent third party appraiser other than Avmark may be substituted
for the appraisal report of Avmark for purposes of this Section 2.01(c).

               (d) In the event Avmark fails or ceases to publish valuation
reports, the Agent shall establish a procedure to determine the value of the
Aviation Property for purposes of Section

<PAGE>

2.01(c). Such procedure shall be acceptable to the Required Banks and based
upon a recognized independent third-party valuation source, and shall also be
established in consultation with the Borrower, but without the approval of the
Borrower.

               (e) The Borrower shall have the right to terminate or reduce
the Commitments at any time and from time to time provided that (i) the
Borrower shall give three (3) Banking Days prior written notice of such
termination or reduction to the Agent specifying the amount and effective date
thereof, (ii) each partial reduction of the Commitments shall be in a minimum
amount of $5,000,000 and in an integral multiple of $1,000,000 and shall
reduce the Commitments of all of the Banks proportionately and in accordance
with the respective Commitment amounts for each Bank, (iii) no such
termination or reduction shall be permitted with respect any portion of the
Commitments as to which a request for an Advance or Letter of Credit Advance
is pending and (iv) the Commitments cannot be terminated if any Advance or
Letter of Credit Advance is then outstanding and may not be reduced below the
principal amount of the Advances and Letter of Credit Advances. The
Commitments or any portion thereof terminated or reduced may not be
reinstated.

          2.02 Requests for Advance.

               (a) Subject to the terms and conditions of this Agreement,
Advances shall be made available to Borrower prior to the Termination Date,
provided that the Agent receives, at the time and in accordance with the terms
of this Section 2.02, a request ("Request") specifying the amount thereof. All
Advances shall be made on a pro rata basis in accordance with each Bank's
Commitment.

               (b) The Borrower shall give the Agent notice of its Request not
later than (i) 11:30 a.m. Indianapolis time (A) three Eurodollar Business Days
prior to the date such Advance is requested to be made if such Advance is to
be made as a Eurodollar Rate Advance, and (B) one day prior to the date such
Advance is requested to be made if such Advance is to be made as a Prime Rate
Advance, which notice shall specify whether a Eurodollar Rate Advance or a
Prime Rate Advance is requested and, in the case of each requested Eurodollar
Rate Advance, the Eurodollar Interest Period to be initially applicable to
such Advance. The Agent, on the same day such Request is received, shall
provide notice of such Request to each Bank.

               (c) Not later than 1:00 p.m. Indianapolis time, on the date of
the Advance, each Bank shall make available the amount of its pro rata share
of each Advance to be made on such date, in immediately available funds to the
Agent at its office specified herein.

               (d) The Agent will thereupon advance to Borrower the amount so
requested unless the Banks shall determine that any condition precedent
applicable to the Advance set forth in Section 4.01 or 4.02 shall not be
fulfilled as of the date of such Advance and the Agent has so notified
Borrower. All Advances will be made to Borrower by a credit to Borrower's
account with the Agent.

               (e) All notices (including Requests for Advances), made by
Borrower to the Agent and received by the Agent after 11:30 a.m., Indianapolis
time, (or such other time as is specified in any section hereof) on a Banking
Day shall be deemed received on the next succeeding Banking Day.

               (f) Each Prime Rate Advance shall be in an aggregate amount of
One Million and 00/100 Dollars ($1,000,000) and each Eurodollar Rate Advance
shall be in an aggregate amount of Five Million and 00/100 Dollars
($5,000,000) and, with respect to both types of Advances, Advances in excess
of such amounts shall be in integral multiples of One Million and 00/100
Dollars

<PAGE>

($1,000,000); provided, however, that in the event that the amount available
to be borrowed is less than One Million and 00/100 Dollars ($1,000,000) in the
case of Prime Rate Advances or Five Million and 00/100 Dollars ($5,000,000) in
the case of Eurodollar Rate Advances, then the Advance shall be permitted in
such lesser amount.

               (g) The failure of any Bank to make its pro rata portion of any
Advance available to the Agent shall not relieve any other Bank of its
obligations to make available its pro rata portion of such Advance on the date
such Advance is requested to be made, but no Bank shall be responsible for
failure of any other Bank to make such pro rata portion available to the Agent
on the date of any such Advance.

          2.03 Evidence of Credit Extensions.

               (a) The Revolving Credit Loans shall be evidenced by a Note
executed by Borrower payable to the order of each Bank in the amount of each
Bank's respective Commitment as set forth on the signature pages hereof dated
the Closing Date, and providing for the payment of principal and interest in
accordance with this Agreement. Each Bank shall record Advances, principal
payments thereof and whether the Advance is a Prime Rate Advance or a
Eurodollar Rate Advance on such Bank's records, and such Bank's record thereof
shall constitute prima facie evidence of the information so recorded. Any
statement of a Bank to Borrower setting forth Borrower's account with such
Bank regarding its share of Advances and payments shall be considered true and
correct and binding on Borrower unless such Bank is notified in writing by
Borrower of any discrepancy or exception within fifteen (15) days from the
mailing by such Bank to Borrower of any such monthly statement.
Notwithstanding the foregoing, the failure to make, or an error in making, a
notation with respect to any Advance shall not limit or otherwise affect the
obligation of Borrower hereunder or under the Notes.

          2.04 Interest.

               (a) Notwithstanding anything herein to the contrary, the
outstanding principal amount of the Revolving Credit Loans, other than during

               Eurodollar Rate Advance, the Eurodollar Rate applicable to such
               Advance for each related Eurodollar Interest Period.

               (b) Borrower shall pay interest on the principal amount of the
Revolving Credit Loans on each Interest Payment Date and at maturity (whether
at stated maturity, by acceleration or otherwise).

               (c) Notwithstanding the foregoing paragraph (a), Borrower shall
pay interest on demand by the Agent at the Overdue Rate on the outstanding
principal amount of any Advance and any other amount payable by the Borrower
hereunder (other than interest) at any time on or after an Event of Default,
if required in writing by the Required Banks.

of issuance through and including the last Banking Day of the first calendar
quarter occurring after the issuance thereof and thereafter, such fee shall be
payable on the last Banking day of each March, June, September and December
during the term of such Letter of Credit. Such fees are nonrefundable and
Borrower shall not be entitled to any rebate of any portion thereof if such
Letter of Credit does not remain outstanding through its stated expiry date or
for any other reason. The Borrower further agrees to pay to the Agent for its
own account, on demand, such other customary administrative fees, charges and
expenses of the Agent in respect of the issuance, negotiation, acceptance,
amendment, transfer and payment of such Letter of Credit or otherwise payable
pursuant to the application and related documentation under which such Letter
of Credit is issued.

          2.07 Computations of Interest and Fees.

               All computations of interest and fees under this Agreement
shall be made on the basis of a year of three hundred sixty (360) days and
calculated for the actual days elapsed. Interest shall accrue on any principal
balance outstanding from and including the date of an Advance to but excluding
the date on which such principal balance is repaid.

          2.08 Method of Payment.

               (a) Each payment of principal, interest and other sums due
under this Agreement shall be made to the Banks without set-off or
counterclaim in immediately available funds on a Banking Day not later than
11:30 a.m., Indianapolis time. All sum received after such time shall be
deemed received on the next Banking Day. Any payment due on a day that is not
a Banking Day shall be made on the next Banking Day.

               (b) Borrower agrees that the Agent may debit any account of
Borrower maintained at the Agent for payments due under this Agreement and the
Agent may credit the any such account with the amount of any Advance.

          2.09 Principal Payments and Prepayments.

               (a) Unless earlier payment is required under this Agreement the
Borrower shall pay to the Banks on the Termination Date the entire outstanding
amount of the Revolving Credit Loans.

               (b) Borrower may prepay all or any portion of the Revolving
Credit Loans provided that Borrower provides the Banks with one Banking Day
prior notice thereof and, further provided, that (i) Borrower may not prepay
any portion of any Revolving Credit Loan as to which an election for a
continuation of or a conversion to a Eurodollar Rate Advance is pending
pursuant to Section 2.13, and (ii) unless earlier payment is required under
this Agreement, any Eurodollar Rate Advance may only be prepaid on the last
day of the then current Eurodollar Interest Period with respect to such
Eurodollar Rate Advance.

               (c) Any prepayment shall be in the amount of One Million and
00/100 Dollars ($1,000,000), any integral multiples thereof or the outstanding
balance if less than One Million and 00/100 Dollars.

               (d) Borrower shall immediately prepay, without notice or
demand, any portion of the outstanding principal balance of the Revolving
Credit Loans, or cash collateralize Letter of Credit Advances if all of the
Revolving Credit Loans are or will be paid in full, by an amount which equals
the amount by which: (i) the sum of the aggregate outstanding principal
balance of the Revolving Credit Loans and the Letter of Credit Advances
exceeds (ii) the lesser of (A) the aggregate amount of the Commitments or (B)
the Borrowing Base.

               (e) If no Event of Default or Default has occurred and is
continuing and if the loss or damage to any Aviation Property is not total or
constructively total and can be repaired within two months from the date of
loss or damage with the proceeds of any casualty insurance policy applicable
to such Aviation Property, then any insurance proceeds recovered by the
Borrower on account of any loss or

<PAGE>

damage to any Aviation Property may be applied by the Borrower solely to the
payment of the cost of any repairs to the Aviation Property, as further
described in the Security Agreement. If the foregoing conditions to repair any
loss or damage to any Aviation Property cannot be satisfied or if any Event of
Default or Default has occurred and is continuing, then upon the payment by
any insurer of any casualty insurance policy applicable to the Aviation
Property of proceeds under any such policy with respect to any Aviation
Property, Borrower shall immediately prepay the Revolving Credit Loans by the
amount of any such proceeds up to an amount equal to one hundred percent
(100%) of the appraised value, as of the most recent Adjustment Date, of the
Aviation Property to which the proceeds relate, for any such proceeds paid
with respect to each L-1011 Aircraft and other Aviation Property, and if such
proceeds exceed the Revolving Credit Loans, the Borrower shall provide cash
collateral for any outstanding Letter of Credit in the amount of such excess.

          2.10 Reborrowing of Prepaid Principal.

               (a) Subject to the terms and conditions hereof, Borrower may
reborrow any portion of the prepaid principal as an Advance provided the sum
of all amounts so reborrowed plus the outstanding principal balance of the
Revolving Credit Loans and of the Letter of Credit Advances does not exceed
the lesser of the Commitments or the Borrowing Base.

          2.11 Letters of Credit.

               (a) Borrower may, from time to time hereafter request the Agent
to issue Letter(s) of Credit in an aggregate principal amount not to exceed
Twenty Five Million and 00/100 Dollars ($25,000,000.00). The Borrower shall
give the Agent notice of its request for a Letter of Credit Advance in writing
not later than 11:30 a.m. Indianapolis time three (3) Banking Days prior to
the date any Letter of Credit Advance is requested to be made and provide such
information as may be necessary for the issuance thereof by the Agent. The
Agent, not later than the Banking Day next succeeding the day such notice is
given, shall provide notice to each Bank of such requested Letter of Credit
Advance and the amount of risk participation therein by such Bank. Subject to
the terms and conditions of this Agreement, the Agent shall, on the date any
Letter of Credit Advance is requested to be made, issue the related Letter of
Credit on behalf of the Banks for the account of the Borrower. Notwithstanding
anything herein to the contrary, the Agent may decline to issue any requested
Letter of Credit on the basis that the beneficiary, the purpose of issuance or
the terms of the conditions of drawing are unacceptable to it in its
reasonable discretion. Upon such issuance by the Agent, each Bank shall
automatically acquire a pro rata risk participation interest in such Letter of
Credit Advance based on its respective Commitment. If the Agent shall honor a
draft or other demand for payment presented or made under any Letter of
Credit, the Agent shall provide notice thereof to each Bank on the date such
draft or demand is honored unless Borrower shall have satisfied its
reimbursement obligation under Section 2.12 by payment to the Agent on such
date. Each Bank, on such date, shall make its pro rata share of the amount
paid by the Agent available in immediately available funds at the principal
office of the Agent for the account of the Agent. If and to the extent such
Bank shall not have made such pro rata portion available to the Agent, such
Bank and Borrower severally agree to pay to the Agent forthwith on demand such
amount together with interest thereon, for each day from the date such amount
was paid by the Agent until such amount is so made available to the Agent at a
per annum rate equal to the interest rate applicable during such period to the
related Advance disbursed under Section 2.12 in respect of the reimbursement
obligation of Borrower. If such Bank shall pay such amount to the Agent
together with such interest, such amount so paid shall constitute a Prime Rate
Advance by such Bank in respect of the reimbursement obligation of the
Borrower under Section 2.12 for purposes of this Agreement. The failure of any
Bank to make its pro rata portion of any such amount paid by the Agent
available to the

<PAGE>

Agent shall not relieve any other Bank of its obligation to make available its
pro rata portion of such amount, but no Bank shall be responsible for failure
of any other Bank to make such pro rata portion available to the Agent.

          2.12 Letter of Credit Reimbursement Payments.

               (a) Borrower agrees to pay to the Agent, on the day on which
the Agent shall honor a draft or other demand for payment presented or made
under any Letter of Credit, an amount equal to the amount paid by the Agent in
respect of such draft or other demand under such Letter of Credit and all
expenses paid or incurred by the Agent relative thereto. Unless Borrower shall
have made such payment to the Agent on such day, upon each such payment by the
Agent, the Agent shall be deemed to have disbursed to Borrower, and Borrower
shall be deemed to have elected to satisfy its reimbursement obligation by a
Prime Rate Advance for the account of the Agent in an amount equal to the
amount so paid by the Agent in respect of such draft or other demand under
such Letter of Credit. Such Advance shall be disbursed notwithstanding any
failure to satisfy any conditions for disbursement of any Advance set forth in
Article IV hereof and, to the extent of the Advance so disbursed, the
reimbursement obligation of Borrower under this Section 2.12 shall be deemed
satisfied.

               (b) The reimbursement obligation of Borrower under this Section
2.12 shall be absolute, unconditional and irrevocable and shall remain in full
force and effect until all obligations of Borrower to the Banks and the Agent
hereunder shall have been satisfied, and such obligations of Borrower shall
not be affected, modified or impaired upon the happening of any event,
including without limitation, any of the following, whether or not with notice
to, or the consent of, Borrower:

                    (i) Any lack of validity or enforceability of any Letter
          of Credit or any documentation relating to any Letter of Credit or
          to any transaction related in any way to such Letter of Credit (the
          "Letter of Credit Documents");

                    (ii) Any amendment, modification, waiver, consent, or any
          substitution, exchange or release of or failure to perfect any
          interest in collateral or security, with respect to any of the
          Letter of Credit Documents:

                    (iii) The existence of any claim, setoff, defense or other
          right which Borrower may have at any time against any beneficiary or
          any transferee of any Letter of Credit (or any persons or entities
          for whom any such beneficiary or any such transferee may be acting),
          the Agent or any Bank or any other person or entity, whether in
          connection with any of the Letter of Credit Documents, the
          transactions contemplated herein or therein or any unrelated
          transactions;

                    (iv) Any draft or other statement or document presented
          under any Letter of Credit proving to be forged, fraudulent, invalid
          or insufficient in any respect by reason of any statement therein
          being untrue or inaccurate in any respect;

                    (v) Payment by the Agent to the beneficiary under any
          Letter of Credit against presentation of any documents which do not
          comply with the terms of the Letter of Credit, including failure of
          any documents to bear any reference or adequate reference to such
          Letter of Credit;

<PAGE>

                    (vi) Any failure, omission, delay or lack on the part of
          the Agent or any party to any of the Letter of Credit Documents to
          enforce, assert or exercise any right, power or remedy conferred
          upon the Agent, any Bank or any such party under this Agreement or
          any of the Letter of Credit Documents, or any other acts or
          omissions on the part of the Agent or any such party;

                    (vii) Any other event or circumstance that would, in the
          absence of this clause, result in the release or discharge by
          operation of law or otherwise of Borrower from the performance or
          observance of any obligation, covenant or agreement contained in
          this Section 2.12.

               (c) No setoff, counterclaim, reduction or diminution of any
obligation or any defense of any kind or nature which Borrower has or may have
against the beneficiary of any Letter of Credit shall be available hereunder
to Borrower against the Agent or any Bank.

          2.13 Subsequent Elections as to Advances. The Borrower may elect (a)
to continue a Eurodollar Rate Advance as a Eurodollar Rate Advance or (b) may
elect to convert a Eurodollar Rate Advance, or a portion thereof, to a Prime
Rate Advance or (c) elect to convert a Prime Rate Advance, or a portion
thereof, to a Eurodollar Rate Advance, in each case by giving notice thereof
to the Agent not later than 11:30 a.m. Indianapolis time three Eurodollar
Business Days prior to the date any such continuation of or conversion to a
Eurodollar Rate Advance is to be effective and not later than 11:30 a.m.
Indianapolis time on the day prior to the day such continuation of or
conversion to a Prime Rate Advance is to be effective, provided that an
outstanding Eurodollar Rate Advance may only be converted on the last day of
the then current Eurodollar Interest Period with respect to such Advance, and
provided, further, if a continuation of an Advance as, or a conversion of an
Advance to, a Eurodollar Rate Advance is requested, such notice shall also
specify the Eurodollar Interest Period to be applicable thereto upon such
continuation or conversion. The Agent, on the same day such notice is given,
shall provide notice of such election to the Banks. If the Borrower shall not
timely deliver such a notice with respect to any outstanding Eurodollar Rate
Advance, the Borrower shall be deemed to have elected to convert such
Eurodollar Rate Advance to a Prime Rate Advance on the last day of the then
current Eurodollar Interest Period with respect to such Advance.

          2.14 Limitations of Requests and Elections. (a) Notwithstanding any
other provision of this Agreement to the contrary, if, upon receiving a
request for a Eurodollar Rate Advance pursuant to Section 2.02 or a request
for a continuation of a Eurodollar Rate Advance as a Eurodollar Rate Advance,
or a request for a conversion of a Prime Rate Advance to a Eurodollar Rate
Advance pursuant to Section 2.13, (i) deposits in Dollars for periods
comparable to the Eurodollar Interest Period elected by the Borrower are not
available to any Bank in the relevant interbank or secondary market, or (ii)
will not adequately and fairly reflect the cost to any Bank of making, funding
or maintaining the Eurodollar Rate Advance or (iii) by reason of national or
international financial, political or economic conditions or by reason of any
applicable law, treaty, rule or regulation (whether domestic or foreign) now
or hereafter in effect, or the interpretation or administration thereof by any
governmental authority charged with the interpretation or administration
thereof, or compliance by any Bank with any guideline, request or directive of
such authority (whether or not having the force of law), including without
limitation exchange controls, it is impracticable, unlawful or impossible for
any Bank (A) to make or fund the relevant Eurodollar Rate Loan or (B) to
continue such Eurodollar Rate Advance as a Eurodollar Rate Advance, or (C) to
convert an Advance to such a Eurodollar Rate Advance, then the Borrower shall
not be entitled, so long as such circumstances continue, to request a
Eurodollar Rate Advance to Section 2.02 or a continuation of or conversion to
a Eurodollar Rate Advance pursuant to Section 2.13. In the

<PAGE>

event that such circumstances no longer exist, the Banks shall again consider
requests for Eurodollar Rate Advances pursuant to Section 2.02, and requests
for continuations of and conversions to Eurodollar Rate Advances pursuant to
Section 2.13.

               (b) Not more than seven Eurodollar Rate Advances may be
outstanding at any one time.

          2.15 Additional Costs. (a) In the event that any applicable law,
treaty or other international agreements, rule or regulation (whether domestic
or foreign) now or hereafter in effect and whether or not presently applicable
to any Bank or the Agent, or any interpretation or administration thereof by
any governmental authority charged with the interpretation or administration
thereof, or compliance by any Bank or the Agent with any guideline, request or
directive of any such authority (whether or not having the force of law),
shall (i) affect the basis of taxation of payments to any Bank or the Agent of
any amounts payable by the Borrower under this Agreement (other than taxes
imposed on the overall net income of the Bank or the Agent, by the
jurisdiction, or by any political subdivision or taxing authority of any such
jurisdiction, in which any Bank or the Agent, as the case may be, has its
principal office), or (ii) shall impose, modify or deem applicable any
reserve, special deposit or similar requirement against assets of, deposits
with or for the account of, or credit extended by any Bank or the Agent, or
(iii) shall impose any other condition with respect to this Agreement, or any
of the Commitments, the Notes or the Advances, and the result of any of the
foregoing is to increase the cost to any Bank or the Agent, as the case may
be, of making, funding or maintaining any Eurodollar Rate Advance or to reduce
the amount of any sum receivable by any Bank or the Agent, as the case may be,
thereon, then the Borrower shall pay to such Bank or the Agent, as the case
may be, from time to time, upon request by such Bank (with a copy of such
request to be provided to the Agent) or the Agent, additional amounts
sufficient to compensate such Bank or the Agent, as the case may be, for such
increased cost or reduced sum receivable to the extent, in the case of any
Eurodollar Rate Advance, such Bank or the Agent is not compensated therefor in
the computation of the interest rate applicable to such Eurodollar Rate
Advance. A statement as to the amount of such increased cost or reduced sum
receivable, prepared in good faith and in reasonable detail by such Bank or
the Agent, as the case may be, and submitted by such Bank or the Agent, as the
case may be, to the Borrower, shall be conclusive and binding for all purposes
absent manifest error in computation.

               (b) In the event that any applicable law, treaty or other
international agreement, rule or regulation (whether domestic or foreign) now
or hereafter in effect and whether or not presently applicable to any Bank or
the Agent, or any interpretation or administration thereof by any governmental
authority charged with the interpretation or administration thereof, or
compliance by any Bank or the Agent with any guideline, request or directive
of any such authority (whether or not having the force of law), including any
risk-based capital guidelines, affects or would affect the amount of capital
required or expected to be maintained by such Bank or the Agent (or any
corporation controlling such Bank or the Agent) and such Bank or the Agent, as
the case may be, determines that the amount of such capital is increased by or
based upon the existence of such Bank's or Agent's Loans or obligations
hereunder and such increase has the effect of reducing the rate of return on
such Bank's or Agent's (or such controlling corporation's) capital as a
consequence of such obligations hereunder to a level below that which such
Bank or Agent (or such controlling corporation) could have achieved but for
such circumstances (taking into consideration its policies with respect to
capital adequacy) by an amount deemed by such Bank or Agent to be material,
then the Borrower shall pay to such Bank or Agent, as the case may be, from
time to time, upon request by such Bank (with a copy of such request to be
provided to Agent) or Agent, additional amounts sufficient to compensate such
Bank or Agent (or such controlling corporation) for any increase in the amount
of capital and reduced rate of return which such Bank or Agent reasonably
determines to be allocable to the existence of such Bank's or Agent's
obligations

<PAGE>

hereunder. A statement as to the amount of such compensation, prepared in good
faith and in reasonable detail by such Bank or Agent, as the case may be, and
submitted by such Bank or Agent to the Borrower, shall be conclusive and
binding for all purposes absent manifest error in computation.

          2.16 Illegality and Impossibility. In the event that any applicable
law, treaty or other international agreement, rule or regulation (whether
domestic or foreign) now or hereafter in effect and whether or not presently
applicable to any Bank, or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration
thereof, or compliance by any Bank with any guideline, request or directive of
such authority (whether or not having the force of law), including without
limitation exchange controls, shall make it unlawful or impossible for any
Bank to maintain any Eurodollar Rate Advance under this Agreement, the
Borrower shall upon receipt of notice thereof from such Bank, repay in full
the then outstanding principal amount of each Eurodollar Rate Advance so
affected, together with all accrued interest thereon to the date of payment
and all amounts owing to such Bank under Section 2.17, (a) on the last day of
the then current Eurodollar Interest Period applicable to such Eurodollar Rate
Advance if such Bank may lawfully continue to maintain such Eurodollar Rate
Advance to such day, or (b) immediately if such Bank may not continue to
maintain such Eurodollar Rate Advance to such day.

          2.17 Indemnification. If the Borrower makes any payment of principal
with respect to any Eurodollar Rate Advance on any other date than the last
day of an Eurodollar Interest Period applicable thereto (whether pursuant to
Sections 2.05(b), Section 2.16, Article VIII or otherwise), or if the Borrower
fails to borrow any Eurodollar Rate Advance after notice has been given to the
Banks in accordance with Section 2.02, or if the Borrower fails to make any
payment of principal or interest in respect of a Eurodollar Rate Advance when
due, the Borrower shall reimburse each Bank on demand for any resulting loss
or expense incurred by each such Bank, including without limitation any loss
incurred in obtaining, liquidating or employing deposits from third parties,
whether or not such Bank shall have funded or committed to fund such
Eurodollar Rate Advance. A statement as to the amount of such loss or expense,
prepared in good faith and in reasonable detail by such Bank and submitted by
such Bank to the Borrower, shall be conclusive and binding for all purposes
absent manifest error in computation. Calculation of all amounts payable to
such Bank under this Section 2.17 shall be made as though such Bank shall have
actually funded or committed to fund the relevant Eurodollar Rate Advance
through the purchase of an underlying deposit in an amount equal to the amount
of such Eurodollar Rate Advance in the relevant market and having a maturity
comparable to the related Eurodollar Interest Period and, through the transfer
of such deposit to a domestic office of such Bank in the United States;
provided, however, that such Bank may fund any Eurodollar Rate Advance in any
manner it sees fit and the foregoing assumption shall be utilized only for the
purpose of calculation of amounts payable under this Section 2.17.

          2.18 Extension of Termination Date. The Termination Date and the
obligation, pursuant to Section 2.09(a) to make mandatory repayment of the
outstanding principal amount of the Loans on the Termination Date shall be
subject to an annual extension, as set forth in this Section 2.18.

               (a) Request for Extension of Termination Date. Notwithstanding
anything contained in this Agreement to the contrary, not later than December
1, 2000 and each December 1 thereafter, the Borrower may, by delivery of a
duly completed Extension Request to the Agent in the form of Exhibit B hereto,
irrevocably request that each Bank extend, for a single one year period, the
Termination Date relating to such Bank's Commitment.

<PAGE>

               (b) Consent to Extension of Termination Date. (i) The Agent
shall, promptly, but not later than 5 days after receipt of any such Extension
Request, pursuant to subsection (a) above, notify each Bank by providing them
a copy of the Extension Request.

                         (ii) Each Bank shall, within 30 days of receipt of
          the Extension Request, notify the Agent whether it consents to the
          request of the Borrower set forth in such Extension Request, such
          consent to be in the sole discretion of such Bank. Each Bank hereby
          acknowledges and agrees that its consent to the Borrower' request to
          extend the Termination Date shall also be deemed to be a consent by
          such Bank to an extension of its obligations to participate,
          pursuant to Section 2.01, in the Letter of Credit Advances. If any
          Bank does not so notify the Agent of its decision within such 30 day
          period, such Bank shall be deemed not to have consented to such
          requests of the Borrower.

                             (iii) The Agent shall promptly notify the
          Borrower whether the Banks have consented to such request. If the
          Agent does not so notify the Borrower by April 1, 1998, and each
          April 1 thereafter, the Agent shall be deemed to have notified the
          Borrower that the Banks have not consented to the Borrower' request.

                             (iv) Each Bank that elects not to extend the
          Termination Date or fails to so notify the Agent of such consent (a
          "Non-Consenting Bank") hereby agrees that if any other Bank or
          financial institution acceptable to the Borrower and the Agent
          offers to purchase such Non-Consenting Bank's Commitment for a
          purchase price equal to the sum of all amounts then owing with
          respect to the Loans and all other amounts accrued for the account
          of such Non-Consenting Bank, such Non-Consenting Bank will promptly
          assign, sell and transfer all of its right, title, interest and
          obligations with respect to the foregoing to such other Bank or
          financial institution pursuant to and on the terms specified in the
          form of Assignment and Acceptance attached hereto as Exhibit C.

                             (v) The pro rata share of the remaining Banks
          which have consented to an extension of their Commitment hereunder
          shall be adjusted accordingly by the Agent, based on such Banks' pro
          rata share of the remaining Commitments as it may be adjusted
          pursuant to clause 2.18 (b)(iv) above or otherwise.

                             (vi) In the event that the Advances of any
          Non-Consenting Bank are not purchased pursuant to clause (iv) above,
          then all of the Banks shall be deemed not to have consented to the
          Borrower request and on the Termination Date the outstanding
          Advances shall be due and payable.

          2.19 Substitution of Bank. If (a) the obligation of any Bank to make
Eurodollar Rate Advances has been suspended pursuant to Section 2.16 when all
Banks have not suspended such obligation or (b) any Bank has demanded
compensation under Section 2.15 when all Banks have not demanded such
compensation, the Borrowers shall have the right to seek a satisfactory
substitute bank (which may be one or more of the other Banks) to purchase the
Note(s) and assume the Commitment(s), if any, of such Bank, with the consent
of the Agent, provided that all amounts owing to such Bank have been paid in
full and such substitution shall be made pursuant to an Assignment and
Acceptance in the form attached hereto as Exhibit C.

                                 ARTICLE III.
                               SECURITY INTEREST

          3.01 Security for Borrowing. (a) As security for the Obligations,
Borrower shall execute and deliver to the Banks and the Agent the Security
Agreement and Chattel Mortgage dated the Closing Date and in form and
substance acceptable to the Agent, as amended or modified from time to time
and together with any other security agreement or other agreement executed in
replacement therefor, granting a first priority, enforceable and perfected
lien and security interest in the Aviation Property and all other assets
described in such Security Agreement and Chattel Mortgage. The Borrower may
also execute and deliver to the Banks and Agent such other Security Agreements
and other agreements and documents, each in form and substance acceptable to
the Agent, granting liens and security interests on other assets of the
Borrower at any time.

               (b) In addition, the Borrower agrees to execute and deliver
such amendments, modifications and/or additional Security Agreements and other
documents and agreements as the Agent may request in order to reaffirm and/or
perfect the security interests intended to be granted by Borrower pursuant to
such Security Agreements and other documents and agreements, or otherwise to
grant a lien and security interest in additional collateral granted pursuant
to this Agreement.

          3.02 Release upon Prepayment. Upon prepayment of the Revolving
Credit Loans in accordance with Section 2.05 from any sale or other transfer
of any Aviation Property, the security interest in such Aviation Property
shall be released and the Borrowing Base shall be reduced, in addition to
other required reductions hereunder, by the amount of such proceeds.

          3.03 Guaranty of Amtran and Affiliates. Amtran and all of its
Subsidiaries will unconditionally guarantee all of the Obligations, and
execute the Guaranty. Any future Subsidiaries of Amtran or the Borrower shall
also unconditionally guarantee all the Obligations, and Amtran and the

provided, however, notwithstanding the actual Adjusted Net Profit for the
fiscal quarters ending September 30, 1996 and December 31, 1996, the Cash Flow

the date hereof, relating to or amending any terms or conditions applicable to
any of such Indebtedness which includes covenants, terms, conditions or
defaults not substantially provided for in this Agreement or more favorable to

shall enter into an amendment to this Agreement or an additional agreement (as
the Agent may request), providing for substantially the same covenants, terms,

more favorable to the holders of the Indebtedness issued in connection
therewith are hereby incorporated by reference into this Agreement to the same
extent as if set forth fully herein, and no subsequent amendment, waiver,
termination or modification thereof shall effect any such covenants, terms,
conditions or defaults as incorporated herein.

upon being directed to do so by the Required Banks, shall, terminate the
Commitments, declare all outstanding principal and accrued and unpaid interest
and all other sums outstanding under or in respect of this Agreement to be

Collateral, and Borrower agrees to deliver such Cash Collateral upon demand,
in an amount equal to the maximum amount that may be available to be drawn at
any time prior to the stated expiry of all outstanding Letters of Credit, or
any one or more of the foregoing, without notice of default, presentment or
demand for payment, protest or notice of nonpayment or dishonor, or other
notices or demands of any kind or character, except as hereinafter specified,
provided, however, that the occurrence of any of the events set forth in
Sections 8.04 or 8.05 shall automatically terminate the Banks' Commitments and
automatically accelerate the amounts due hereunder, including such Cash
Collateral, and under the Notes, without notice of default, presentment or
demand for payment, protest or notice of nonpayment or dishonor, or other
notice or demands for payment of any kind or character.

          8.01 Nonpayment. Borrower shall fail to pay when due any installment
of principal or of interest or any other sum due under this Agreement in
accordance with the terms hereof or of any Note issued under this Agreement
and such failure continues for five (5) days.

          8.02 Representation or Warranty. Any written representation or
warranty herein or in any of the Loan Documents or any other agreement,
instrument or certificate executed pursuant hereto shall prove to have been
false or misleading in any material respect when made or when deemed to have

          8.03 Other Defaults. (i) Borrower or Amtran shall fail duly or
promptly to perform or observe the covenants contained in Sections 6.09, 6.10
and 6.11 hereof or any of the other covenants, agreements or conditions
contained in any Loan Document and such default in such other covenants,
agreements or conditions shall continue unremedied for a period of thirty (30)
days after written notice thereof is delivered to Borrower from the Agent, or
(ii) any Default or Event of Default (however designated) shall have occurred
under any of the other Loan Documents and shall not have been cured within the
applicable grace or cure period, if any.

          8.04 Voluntary Bankruptcy. The Borrower or Amtran or any of Amtran's
other Affiliates shall generally fail to pay or admit in writing its inability
to pay its debts as they come due, or shall file any petition or action for

relating to, debtors, or shall apply for or consent to a receiver, trustee or
custodian for it or a substantial portion of its property, or shall make a
general assignment for the benefit of creditors.

          8.05 Involuntary Bankruptcy. An involuntary petition shall be filed
under any bankruptcy or similar statute against Borrower or Amtran or any of
Amtran's other Affiliates or a custodian, receiver, trustee, assignee for the
benefit of creditors (or other similar official) shall be appointed to take
possession, custody or control of the properties of Borrower or Amtran or any
of Amtran's other Affiliates unless such petition or appointment is set aside
or withdrawn or ceases to be in effect within sixty (60) days from the date of
said filing or appointment.

<PAGE>

          8.06 Cross Default. Any material breach or default shall have
occurred (after giving effect to any applicable cure period or waiver) under
any other agreement or agreements relating to Indebtedness under which
Borrower or any of its Affiliates may be obligated in an aggregate amount in
excess of $5,000,000 as borrower, guarantor or lessee if such default consists
of (i) the failure by Borrower to pay an Indebtedness when due or the failure
of the Borrower or any of its Affiliates to perform or observe any other term,
covenant or agreement with respect to any such Indebtedness and following any
applicable cure period, permits the holder or any trustee thereof to cause the
acceleration of such Indebtedness (including without limitation permitting the
holder or any trustee thereof to require any mandatory prepayment or
defeasance of such Indebtedness) or the termination of any commitment to lend
or permits a lessor to terminate the applicable lease, including without
limitation any "Event of Default" under any of the Senior Unsecured Debt
Documents or the occurrence of any event or condition which would permit the
holders of the Senior Unsecured Notes to cause the prepayment or defeasance of
the Senior Unsecured Notes, in whole or in part, or (ii) the failure by
Borrower to pay an Indebtedness at the maturity thereof (whether at stated
maturity or otherwise).

meaning of Title IV of ERISA except as permitted by section 4044(d) of ERISA,
or a trustee shall be appointed by the appropriate United States District
Court to administer any Plan of Borrower, or the PBGC shall institute
proceedings to terminate any Plan.

condemned, confiscated, seized, or otherwise expropriated, or the management
thereof assumed, by any government or any officer or instrumentality thereof
and shall be retained for any period of thirty (30) consecutive calendar days,
unless within such thirty (30) day period the Agent shall receive assurances,
satisfactory in all respects to the Agent, that Borrower will be compensated
therefore in amount, time and manner satisfactory in all respects to the Agent
or, after giving effect to any event described herein and the deletion of such
affected Aviation Property from the Borrowing Base and any payments made on
the Advances in connection therewith, the aggregate Advances and Letter of
Credit Advances would not exceed the Borrowing Base.

          8.09 Ownership. J. George Mikelsons or his heirs shall own
beneficially and of record, free and clear of all Liens, less than fifty-one
percent (51%) of the outstanding capital stock or other ownership interest of
each class having ordinary voting power or analogous rights for the election
of a majority of directors and any other control of management of Amtran, or
Amtran shall own, beneficially and of record, free and clear of all Liens,
less than fifty-one percent (51%) of the outstanding capital stock or other
ownership interest of each class having ordinary voting power or analogous
rights for the election of a majority of directors and any other control of
management of the Borrower or any "Change of Control" as defined in the Senior
Unsecured Debt Documents.

          8.10 Judgments. One or more judgments or orders for the payment of
money in an aggregate amount of $1,000,000 shall be rendered against Amtran or
any of its Affiliates, or any other judgment or order (whether or not for the
payment of money) shall be rendered against or shall affect Amtran or any of
its Affiliates which causes or could cause a material adverse change in the
business, properties, operations or condition, financial or otherwise, of
Amtran or any of its Affiliates or which does or could have a material adverse
effect on the legality, validity or enforceability of this Agreement, the
Notes, the Guaranty or the Security Agreement, and either (i) such judgment or
order shall have remained unsatisfied and Amtran or such Affiliate shall not
have taken action necessary to stay enforcement thereof by reason of pending
appeal or otherwise, prior to the expiration of the applicable period of
limitations for taking such action or, if such action shall have been taken, a
final order denying

<PAGE>

such stay shall have been rendered, or (ii) enforcement proceedings shall have
been commenced by any creditor upon any such judgment or order.

                                  ARTICLE IX.
                    RELATIONSHIP OF THE BANKS/AND THE AGENT

          9.01 Appointment and Authorization. Each Bank hereby irrevocably
authorizes the Agent to take such action as agent on its behalf and to
exercise such rights, powers and discretions as are specifically delegated in
this Agreement, the Notes and the Security Documents as are delegated to the
Agent by the terms hereof or thereof, together with all rights, powers and
discretions as are reasonably incidental thereto. The Agent agrees to notify
the Banks of each reduction in the Commitments, specifying the amount of such
reduction and the payments, if any, required by the Borrower due to such
reduction, and agrees to forward to the Banks the financial statements
received by the Agent pursuant to Section 6.03 hereof and such other financial
information received by the Agent as reasonably requested by the Banks. The
Agent may perform any of its respective functions and duties under this
Agreement by or through agents or its directors, officers of employees. In
performing its functions and duties under this Agreement, the Agent shall not
be deemed to have a fiduciary relationship in respect of, or other
responsibility to (other than responsibilities expressly stated herein), any
Bank or to have assumed any relationship of agency or trust with or for
Borrower.

          9.02 Pro Rata Sharing. All payments or collections of principal and
interest on the Revolving Credit Loans shall be shared by the Banks on a pro
rata basis based upon the share of outstanding Indebtedness of the Borrower to
each Bank at the time of such payment or collection. On the day the Agent
receives any payments hereunder, the Agent shall remit to the Banks their pro
rata share of such payments in immediately available funds.

          9.03 Sharing of Setoff. Any Bank which shall receive payment of or
on account of all or part of its share of the Obligations by voluntary payment
by Borrower or through the exercise of any right of setoff, counterclaim,
banker's lien, secured claim under any bankruptcy statute or otherwise in a
greater proportion than the proportionate amount of the Obligations due it
under this Agreement shall be deemed to have purchased immediately prior to
such payment participations in the portions of the Obligations held by the
other Banks so that all recoveries of the Obligations shall be shared by Banks
in accordance with their pro rata interests in the Obligations existing on the
date immediately prior to such recovery. If all or any portion of such excess
payment is thereafter recovered from such Bank, such purchase shall be
rescinded and the purchase price restored to the extent of such recovery, but
without interest (except to the extent of such Bank is required to pay
interest). All sums received by a Bank through the exercise of any right of
setoff, counterclaim, banker's lien, secured claim under any bankruptcy
statute or otherwise shall be deemed to be first applied to such Bank's
portion of the indebtedness under this Agreement until payment thereof in full
and any balance remaining thereafter shall be deemed applied to any other
Indebtedness of the Borrower to such Bank.

          9.04 Approvals. Except as provided in this Section 9.04, upon any
occasion requiring or permitting an approval, consent, waiver, election or
other action on the part of the Banks, action shall be taken by the Agent for
and on behalf or for the benefit of all Banks upon the direction of the
Required Banks, and any such action shall be binding on all Banks. No
amendment, modification, consent or waiver shall be effective which:

               (a) increases the Commitment of any Bank,

<PAGE>

               (b) reduces the amount of interest, principal or fees owing
hereunder or reduces the interest rate or fees payable by Borrower,

               (c) extends the fixed date on which any sum is due hereunder,
or extends the Termination Date,

               (d) waives a Default arising from a failure to pay principal of
or interest on an Advance within the applicable grace period,

               (e) changes the provisions of this Section 9.04,

               (f) releases or substitutes all or substantially all of the
collateral, other than substitutions of collateral where the collateral to
be added is of approximately equal or greater value than the collateral
being released,

               (g) modifies the definition of "Required Banks",

               (h) releases any material Guarantor from the Guaranty, or

               (i) waives any violation of the advance rate on Aviation
Property or changes such advance rate.

unless all Banks agree in writing thereto; provided, however, that any
amendment, modification, consent or waiver which affects the rights, duties or
obligations of the Agent shall not be effective unless consented to in writing
by the Agent.

          9.05 Exculpation. The Agent shall not be liable or answerable for
anything whatsoever in connection with this Agreement or any instrument or
agreement required hereunder, including responsibility with respect to the
execution, construction or enforcement of this Agreement or any such
instrument or agreement, except for its own respective willful misconduct or
gross negligence, and the Agent shall not have any duties or obligations other
than as provided herein and therein. The Agent shall be entitled to rely on
any opinion of counsel (including counsel for Borrower) in relation to this
Agreement and any instrument or agreement required hereunder, and upon
statements and communications received from Borrower, or from any other
person, believed by it to be authentic, and shall not be liable for any action
taken or omitted in good faith on such reliance.

          9.06 Indemnification.

          Each Bank agrees to indemnify the Agent to the extent not reimbursed
by Borrower, ratably according to its proportionate interest in the Revolving
Credit Loans (or, if there are no outstandings hereunder, in the Commitments),
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may be imposed on incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement or
any instrument or agreement required hereunder or any action taken or omitted
by the Agent in such role under this Agreement or any such instrument or
agreement; provided that no Bank shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever
resulting from the Agent's willful misconduct or gross negligence.

<PAGE>

          9.07 The Agent as Bank. The Agent shall have the same rights and
powers hereunder as any other Bank and may exercise the same as though it were
not the Agent; and the Term "Banks" shall include the Agent in its individual
capacity.

          9.08 Notices of Transfer. The Agent and Borrower may deem and treat
a Bank which is a party to this Agreement as the owner of such Bank's Note for
all purposes hereof unless and until a written notice of the assignment or
transfer, thereof (if any is permitted) executed by such Bank shall have been
received by the Agent and Borrower.

          9.09 Credit Decision. Each Bank represents that it has made and
agrees that it shall continue to make its own independent investigation of the
financial condition and affairs of Borrower and its own appraisal of the
creditworthiness of the Borrower in connection with the making of the
continuance of its Commitments and the Advances. The Agent has no any duty or
responsibility, either initially or on a continuing basis, to provide any Bank
with any credit or other information (other than obtained pursuant to this
Agreement) with respect thereto, whether coming into its possession before the
date hereof or at any time thereafter unless furnished respectively to the
Agent by Borrower for delivery to the Banks. The Agent shall provide the Banks
with copies of all notices required by the Agreement provided to Agent
respectively by or to Borrower.

          9.10 Resignation of the Agent. The Agent may resign at any time by
giving written notice to the Banks and Borrower. Upon any such resignation,
the Required Banks with the prior written consent of Borrower which shall not
be unreasonably withheld, shall have the right to appoint a successor from
among the Banks. If no successor shall have accepted such appointment within
forty-five (45) days after the retiring Agent's giving of notice of
resignation, the retiring Agent may, on behalf of the Banks, appoint a
successor thereto with the prior written consent of Borrower, which shall not
be unreasonably withheld, and such successor Agent shall be a bank or trust
company organized under the laws of the United States or any state thereof.
Upon the acceptance by such successor of its appointment hereunder, such
successor shall succeed to and become vested with all the rights and
obligations of the retiring Agent, and the retiring Agent shall be discharged
from its obligations under this Agreement except with respect to any liability
with respect to a breach of any obligation hereunder prior to such
resignation. The provisions of this Section 9.11 shall inure to the benefit of
the retiring Agent as to any actions taken or omitted to be taken by it while
it held such position under this Agreement.

          10.02 Successors and Assigns. This Agreement shall bind and inure to

<PAGE>

          10.03 Participations and Assignments. (a) This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, provided that the Borrower may not, without
the prior consent of the Banks, assign its rights or obligations hereunder or
under any other Loan Document and the Banks shall not be obligated to make any
Loan hereunder to any entity other than the Borrower.

               (b) Any Bank may sell to any bank, financial institution or
institutions or other entity, and such bank, financial institution or
institutions or other entity may further sell, a participation interest
(undivided or divided) in, the Loans and such Bank's rights and benefits under
this Agreement, the Notes and the Guaranties, and to the extent of that
participation interest such participant or participants shall have the same
rights and benefits against the Borrower under Section 2.15 and 2.17 as it or
they would have had if such participant or participants were the Bank making
the Loans to the Borrower hereunder, provided, however, that (i) such Bank's
obligations under this Agreement shall remain unmodified and fully effective
and enforceable against such Bank, (ii) such Bank shall remain solely
responsible to the other parties hereto for the performance of such
obligations, (iii) such Bank shall remain the holder of its Notes for all
purposes of this Agreement, (iv) the Borrower, the Agent and the other Banks
shall continue to deal solely and directly with such Bank in connection with
such Bank's rights and obligations under this Agreement, and (v) such Bank
shall not grant to its participant any rights to consent or withhold consent
to any action taken by such Bank or the Agent under this Agreement other than
action requiring the consent of all of the Banks hereunder.

               (c) Each Bank may, with the prior consent of the Agent, assign
to one or more banks or other entities all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitment, the Loans owing to it and the Note or Notes held by
it); provided, however, that (i) each such assignment shall be of a uniform,
and not a varying, percentage of all rights and obligations, (ii) except in
the case of an assignment of all of a Bank's rights and obligations under this
Agreement, (A) the amount of the Commitment of the assigning Bank being
assigned pursuant to each such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event
be less than $5,000,000, and in integral multiples of $1,000,000 thereafter,
or such lesser amount as the Agent may consent to and (B) after giving effect
to each such assignment, the amount of the Commitment of the assigning Bank
shall in no event be less than $5,000,000, (iii) the parties to each such
assignment shall execute and deliver to the Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance in the form of Exhibit
C hereto (an "Assignment and Acceptance"), together with any Note or Notes
subject to such assignment and, a processing and recordation fee of $3,000,
and (iv) any Bank may without the consent of the Borrower or the Agent, assign
to any Affiliate of such Bank that is a bank or financial institution all of
its rights and obligations under this Agreement. Upon such execution,
delivery, acceptance and recording, from and after the effective date
specified in such Assignment and Acceptance, (x) the assignee thereunder shall
be a party hereto and, to the extent that rights and obligations hereunder
have been assigned to it pursuant to such Assignment and Acceptance, have the
rights and obligations of a Bank hereunder and (y) the Bank assignor
thereunder shall, to the extent that rights and obligations hereunder have
been assigned by it pursuant to such Assignment and Acceptance, relinquish its
rights and be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all of the remaining portion of
an assigning Bank's rights and obligations under this Agreement, such Bank
shall cease to be a party hereto).

               (d) The Agent shall maintain at its address designated on the
signature pages hereof a copy of each Assignment and Acceptance delivered to
and accepted by it and a register for the recordation of the names and
addresses of the Banks and the Commitment of, and principal amount of the
Loans owing to, each Bank from time to time (the "Register"). The entries in
the Register shall be

<PAGE>

conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Agent and the Banks may treat each Person whose name is recorded
in the Register as a Bank hereunder for all purposes of this Agreement. The
Register shall be available for inspection by the Borrower or any Bank at any
reasonable time and from time to time upon reasonable prior notice.

               (e) Upon its receipt of an Assignment and Acceptance executed
by an assigning Bank and an assignee, together with any Note or Notes subject
to such assignment, the Agent shall, if such Assignment and Acceptance has
been completed, (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register and (iii) give prompt notice
thereof to the Borrower. Within ten Business Days after its receipt of such
notice, the Borrower, at its own expense, shall execute and deliver to the
Agent in exchange for the surrendered Note or Notes a new Note to the order of
such assignee in an amount equal to the Commitment assumed by it pursuant to
such Assignment and Acceptance and, if the assigning Bank has retained a
Commitment hereunder, a new Note to the order of the assigning Bank in an
amount equal to the Commitment retained by it hereunder. Such new Note or
Notes shall be in an aggregate principal amount equal to the aggregate
principal amount of such surrendered Note or Notes, shall be dated the
effective date of such Assignment and Acceptance and shall otherwise be in
substantially the form of Exhibit C hereto.

               (f) The Banks may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
10.03, disclose to the assignee or participant or proposed assignee or
participant any public information relating to the Borrower and, provided that
such proposed assignee or participant executes a confidentiality letter, any
other information relating to the Borrower.

          10.04 Delays and Waivers. No delay or omission by the Banks to
exercise any right under this Agreement shall impair any such right, nor shall
it be construed to be a waiver thereof. No waiver of any single breach or
default under this Agreement shall be deemed a waiver of any other breach or
default. Any waiver, modification, amendment, consent or approval relating to
this Agreement or the Notes, must be in writing to be effective and must be
signed by or on behalf of the Banks.

          10.05 Costs and Expenses. (a) The Borrower agrees to pay on demand
to the Banks all costs and expenses incurred by the Banks including, without
limitation, reasonable attorneys' and consultants' fees (i) in connection with
the enforcement of this Agreement or any instrument or agreement required
hereunder or in connection with any proposed refinancing or restructuring of
the credit provided in this Agreement in the nature of a "work-out" and (ii)
for all stamp, registration and other duties and imposts to which this
Agreement and any instrument or agreement required hereunder may be subject.
The Borrower agrees to pay or to reimburse the Agent upon demand for
reasonable attorneys' fees and other expenses incurred in connection with the
preparation, drafting and negotiation of this Agreement, the Notes, and the
Loan Documents, any amendments, consents, or waivers hereto or thereto. The
Borrower shall indemnify the Banks against any and all liabilities and
penalties resulting from any delay in payment, or failure to pay, any such
duties and imposts upon written notice from the Banks that such amounts have
been assessed.

               (b) Borrower agrees to indemnify the Agent and each Bank, their
respective affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel, which may be incurred by such Indemnitee at any time
in connection with any investigative, administrative or judicial proceeding
(whether or not such Indemnitee shall be designated a

<PAGE>

party thereto) brought or threatened relating to or arising out of the Loan
Documents, any actual or proposed use of proceeds of the Loans or the Letter
of Credit Advances, any transactions relating to any of the foregoing, any act
or omission of Borrower or any Guarantor or any environmental liability of
Borrower or any Guarantor; provided that no Indemnitee shall have the right to
be indemnified hereunder for such Indemnitee's own gross negligence or willful
misconduct as determined by a court of competent jurisdiction.

          10.06 Entire Agreement. This Agreement and any agreement, document
or instrument attached hereto or referred to herein integrate all the terms
and conditions mentioned herein or incidental hereto, and supersede all oral
negotiations and prior writings in respect to the subject matter hereof. In
the event of any conflict between the terms, conditions and provisions of this
Agreement and any such agreement, document or instrument, the terms,
conditions and provisions of this Agreement shall prevail.

          10.07 Prior Agreement. Upon the execution of this Agreement, the
Commitments of the banks pursuant to the Prior Agreement shall terminate and
be deemed superseded by the Commitments under this Agreement, and this
Agreement is an amendment and restatement of the Prior Credit Agreement,
without novation thereof. The Borrower and Amtran acknowledge they have no
setoff, defense, claim or other dispute in connection with any of the
indebtedness or other liabilities owing pursuant to the Prior Agreement or
otherwise in connection with the Prior Agreement. Any Indebtedness outstanding
under the Prior Agreement after the Closing Date shall be deemed Indebtedness
outstanding under this Agreement. All liens and security interests granted
with respect to the Aviation Property in connection with the Prior Credit
Agreement shall continue in full force and effect and secure the Obligations
and other indebtedness and liabilities described in the Security Agreement,
and all filings with the FAA and all UCC financing statements filed shall
continue in full force and effect.

          10.08 Governing Law. This Agreement is a contract made under, and
shall be governed by and construed in accordance with, the laws of the State
of Michigan applicable to contracts made and to be performed entirely within
such State and without giving effect to the choice of law principles of such
State.

          10.09 Section Headings. Section headings are for reference only, and
shall not affect the interpretation or meanings of any provision of this
Agreement.

          10.10 Severability. The illegality or unenforceability of any
provision of this Agreement or any instrument or agreement required hereunder
shall not in any way affect or impair the legality or enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder.

          10.11 Counterparts. This Agreement may be executed simultaneously in
any number of counterparts, all of which taken together will constitute one
agreement, and any one of the parties hereto may execute this Agreement by
signing any such counterpart.

          10.12 Waiver of Jury Trial. The Agent, the Banks, Amtran and the
Borrower, after consulting or having had the opportunity to consult with
counsel, each knowingly, voluntarily and intentionally waive any right any of
them may have to a trial by jury in any litigation based upon or arising out
of this Agreement or any related instrument or agreement or any of the
transactions contemplated by this Agreement or any course of conduct, dealing,
statements (whether oral or written)

<PAGE>

or actions of any of them. Neither the Agent, the Banks, Amtran nor the
Borrower shall seek to consolidate, by counterclaim or otherwise, any such
action in which a jury trial has been waived with any other action in which a
jury trial cannot be or has not been waived. These provisions shall not be
deemed to have been modified in any respect or relinquished by the Agent, the
Agent, the Banks, Amtran or the Borrower except by a written instrument
executed by all of them.

<PAGE>

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement
by their duly authorized officers as of the date and year first above written.

Agreement and the Note in respect of the interest assigned hereby (including,
without limitation, all payments of principal, interest and commitment fees
with respect thereto) to the Assignee. The Assignor and Assignee shall make

which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement. Delivery of an
executed counterpart of Schedule 1 to this Assignment and Acceptance by

          (b) All payments to be made under this Guaranty (except pursuant to

addition or supplement to the Liabilities or any Agreement; (b) any extension,
indulgence, increase in the Liabilities or other action or inaction in respect

                                      -2-

<PAGE>

irregularity or other defect in, any of the Agreements; (d) any waiver by any
Lender or any other person of any required performance or otherwise of any
condition precedent or waiver of any requirement imposed by any of the
Agreements, any other guaranties or otherwise with respect to the Liabilities;
(e) any exercise or non-exercise of any right, remedy, power or privilege in
respect of this Guaranty, any other guaranty or any of the Agreements; (f) any

corporation, or entity, or any transfer or other disposition of any shares of
capital stock of the Borrower; (g) any bankruptcy, insolvency, reorganization
or similar proceedings involving or affecting the Borrower or any other
guarantor of the Liabilities; (h) the release or discharge of the Borrower
from the performance or observance of any agreement, covenant, term or
condition under any of the Liabilities or contained in any of the Agreements,
of any Cumulative Guarantor or of this Guaranty, by operation of law or
otherwise; or (i) any other cause whether similar or dissimilar to the
foregoing which, in the absence of this provision, would release, affect or
impair the obligations, covenants, agreements and duties of any Guarantor
hereunder, including without limitation any act or omission by any Lender or
any other any person which increases the scope of any Guarantor's risk; and in
each case described in this paragraph whether or not any Guarantor shall have
notice or knowledge of any of the foregoing, each of which is specifically
waived by each Guarantor. Each Guarantor warrants to the Lenders that it has
adequate means to obtain from the Borrower on a continuing basis information
concerning the financial condition and other matters with respect to the
Borrower and that it is not relying on any Lender to provide such information
either now or in the future.

     4. Waivers, Etc. Each Guarantor unconditionally waives: (a) notice of any
of the matters referred to in Paragraph 3 above; (b) all notices which may be
required by statute, rule of law or otherwise to preserve any rights of any
Lender, including, without limitation, notice to the Guarantors of default,
presentment to and demand of payment or performance from the Borrower and
protest for non-payment or dishonor; (c) any right to the exercise by any
Lender of any right, remedy, power or privilege in connection with any of the
Agreements; (d) any requirement of diligence or marshaling on the part of any
Lender; (e) any requirement that any Lender, in the event of any default by
the Borrower, first make demand upon or seek to enforce remedies against, the
Borrower or any other Cumulative Guarantor before demanding payment under or
seeking to enforce this Guaranty; (f) any right to notice of the disposition
of any security which any Lender may hold from the Borrower or otherwise and
any right to object to the commercial reasonableness of the disposition of any
such security; and (g) all errors and omissions in connection with any
Lender's administration of any of the Liabilities, any of the Agreements or
any other Cumulative Guarantor, or any other act or omission of any Lender
which changes the scope of such Guarantor's risk. The obligations of each
Guarantor hereunder shall be complete and binding forthwith upon the execution
of this Guaranty by it and subject to no condition whatsoever, precedent or
otherwise, and notice of acceptance hereof or action in reliance hereon shall
not be required.

     5. Nature of Guaranty; Payments. This Guaranty is an absolute,
unconditional, irrevocable and continuing guaranty of payment and not a
guaranty of collection, and is wholly independent of and in addition to other
rights and remedies of any Lender with respect to the Borrower, any
collateral, any Cumulative Guarantor or otherwise, and it is not contingent
upon the pursuit by any Lender of any such rights and remedies, such pursuit
being hereby waived by each Guarantor. The obligations of each Guarantor
hereunder shall be continuing and shall continue (irrespective of any statute
of limitations otherwise applicable) and cover and include all the Liabilities
of the Borrower accruing or in the process of

                              GUARANTY AGREEMENT

                                      -3-

<PAGE>

accruing to the Lenders before the Lenders deliver to the Guarantors a release
of this Guaranty, which is in writing, refers specifically to this Guaranty,
and is signed by a President, a Senior Vice President, or a Vice President of
each Lender. Nothing shall discharge or satisfy the liability of any Guarantor
hereunder except the full and irrevocable payment and performance of all of
the Liabilities and the expiration or termination of all the Agreements. All
payments to be made by the Guarantors hereunder shall be made without set-offs
or counterclaim, and each Guarantor hereby waives the assertion of any such
set-offs or counterclaims in any proceeding to enforce its obligations
hereunder. All payments to be made by each Guarantor hereunder shall also be
made without deduction or withholding for, or on account of, any present or
future taxes or other similar charges of whatsoever nature, provided that if
any Guarantor is nevertheless required by law to make any deduction or
withholding, such Guarantor shall pay to the Lenders such additional amounts
as may be necessary to ensure that the Lenders shall receive a net sum equal
to the sum which it would have received had no such deduction or withholding
been made. Each Guarantor agrees that, if at any time all or any part of any
payment previously applied by any Lender to any of the Liabilities must be
returned by such Lender for any reason, whether by court order, administrative
order, or settlement and whether as a "voidable preference", "fraudulent
conveyance" or otherwise, each Guarantor remains liable for the full amount
returned as if such amount had never been received by such Lender,
notwithstanding any termination of this Guaranty or any cancellation of any of
the Agreements and the Liabilities and all obligations of each Guarantor
hereunder shall be reinstated in such case.

     6. Evidence of Liabilities. Each Lender's books and records showing the
Liabilities shall be admissible in any action or proceeding, shall be binding
upon each Guarantor for the purpose of establishing the Liabilities due from
the Borrower and shall constitute prima facie proof, absent manifest error, of
the Liabilities of the Borrower to such Lender, as well as the obligations of
each Guarantor to such Lender.

     7. Subordination, Subrogation, Contribution, Etc. Each Guarantor agrees
that all present and future indebtedness, obligations and liabilities of the
Borrower to such Guarantor shall be fully subordinate and junior in right and
priority of payment to any indebtedness of the Borrower to the Lenders, and,
notwithstanding anything in this Guaranty or under any other guaranty or other
agreement to the contrary, each Guarantor hereby irrevocably waives all rights
of subrogation, contribution, reimbursement or indemnity whatsoever and all
rights of recourse to security for the debts and obligations of the Borrower,
whether arising under this Guaranty, under any other guaranty or agreement, by
operation of law or otherwise.

     8. Assignment by Lenders. Each Lender shall have the right to assign and
transfer this Guaranty to any assignee of any portion of the Liabilities. Each
Lender's successors and assigns hereunder shall have the right to rely upon
and enforce this Guaranty.

     9. Joint and Several Obligations. The obligations of the Guarantors
hereunder and all other Cumulative Guarantors shall be joint and several and
each Guarantor shall be liable for all of the Liabilities to the extent
provided herein regardless of any other Cumulative Guarantors, and each Lender
shall have the right, in its sole discretion to pursue its remedies against
any Guarantor without the need to pursue its remedies against any other
Cumulative Guarantor, whether now or hereafter in existence, or against any
one or more Cumulative Guarantors separately or against any two or more
jointly, or against some separately and some jointly.

     10. Representations and Warranties. Each Guarantor hereby represents and
warrants to the Lenders that:

          (a) the execution, delivery and performance by the Guarantor of this
Guaranty are within its corporate powers, have been duly authorized by all
necessary corporate action, require no action by or in respect of, or filing
with, any governmental body, agency or official, and do not contravene or
constitute a default under, any provision of applicable law or regulation or
of the articles of incorporation or other charter documents or bylaws of such
Guarantor, or of any agreement, judgment, injunction, order, decree or other
instrument binding upon such Guarantor, or result in the creation or
imposition of any lien, security interest or other charge or encumbrance on
any asset of such Guarantor;

          (b) this Guaranty constitutes a legal, valid and binding agreement
of each Guarantor, enforceable against the Guarantor in accordance with its
terms;

          (c) as of the date hereof, each of the following is true and correct
for each of Amtran, Inc, Ambassadair Travel Club, Inc., ATA Vacations, Inc,
Amber Travel, Inc. and Amber Air Freight Corporation: (i) the fair saleable
value and the fair valuation of such Guarantor's property is greater than the
total amount of its liabilities (including contingent liabilities) and greater
than the amount that would be required to pay its probable aggregate liability
on its existing debts as they become absolute and matured, (ii) each
Guarantor's capital is not unreasonably small in relation to its current
and/or contemplated business or other undertaken transactions, and (iii) each
Guarantor does not intend to incur, or believe that it will incur, debt beyond
its ability to pay such debts as they become due; and

          (d) the Borrower, the Guarantors and the other affiliates of the
Borrower are engaged as an integrated group in the business of providing air
travel and related services; that the integrated operation requires financing
on such a basis that credit supplied to the Borrower can be made available
from time to time to various subsidiaries of the Borrower, as required for the
continued successful operation of the integrated group as a whole; and that
each Guarantor has requested the Lenders to continue to lend and to make
credit available to the Borrower for the purpose of financing the integrated
operations of the Borrower and its subsidiaries, including each Guarantor,
with each Guarantor expecting to derive benefit, direct or indirectly, from
the loans and other credit extended by the Lenders to the Borrower, both in
such Guarantor's separate capacity and as a member of the integrated group,
inasmuch as the successful operation and condition of each Guarantor is
dependent upon the continued successful performance of the functions of the
integrated group as a whole. Each of the Guarantors hereby determines and
agrees that the execution, delivery and performance of this Guaranty are
necessary and convenient to the conduct, promotion or attainment of the
business of such Guarantor and in furtherance of the corporate purposes of
such Guarantor.

     11. Binding on Successors and Assigns. This Guaranty shall be the valid,
binding and enforceable obligation of the Guarantors and their successors and
assigns.

                              GUARANTY AGREEMENT

                                      -5-

<PAGE>

     12. Indemnity. As a separate, additional and continuing obligation, each
Guarantor unconditionally and irrevocably undertakes and agrees with each
Lender that, should the Liabilities not be recoverable from any Guarantor as
guarantor under this Guaranty for any reason whatsoever (including, without
limitation, by reason of any provision of any of the Liabilities or the
Agreements being or becoming void, unenforceable, or otherwise invalid under
any applicable law) then, notwithstanding any knowledge thereof by any Lender
at any time, each Guarantor as original and independent obligor, upon demand
by the Lenders, will make payment to the Lenders of the Liabilities by way of
a full indemnity.

     13. Cumulative Rights and Remedies, Etc. The obligations of each
Guarantor under this Guaranty are continuing obligations and a new cause of
action shall arise in respect of each default hereunder. No course of dealing
on the part of any Lender, nor any delay or failure on the part of any Lender
in exercising any right, power or privilege hereunder, shall operate as a
waiver of such right, power, or privilege or otherwise prejudice the Lenders'
rights and remedies hereunder; nor shall any single or partial exercise
thereof preclude any further exercise thereof or the exercise of any other
right, power or privilege. No right or remedy conferred upon or reserved to
any Lender under this Guaranty is intended to be exclusive of any other right
or remedy, and every right and remedy shall be cumulative and in addition to
every other right or remedy given hereunder or now or hereafter existing under
any applicable law. Every right and remedy given by this Guaranty or by
applicable law to the Lenders may be exercised from time to time and as often
as may be deemed expedient by any Lender.

     14. Severability. If any one or more provisions of this Guaranty should
be invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein shall not in
any way be affected, impaired, prejudiced or disturbed thereby, and any
provision hereunder found partially unenforceable shall be interpreted to be
enforceable to the fullest extent possible. If at any time all or any portion
of the obligation of any Guarantor under this Guaranty would otherwise be
determined by a court of competent jurisdiction to be invalid, unenforceable
or avoidable under Section 548 of the federal Bankruptcy Code or under any
fraudulent conveyance or transfer laws or similar applicable law of any
jurisdiction, then notwithstanding any other provisions of this Guaranty to
the contrary such obligation or portion thereof of such Guarantor under this
Guaranty shall be limited to the greatest of (i) the value of any quantified
economic benefits accruing to such Guarantor as a result of this Guaranty,
(ii) an amount equal to 95% of the excess on the date the relevant Liabilities
were incurred of the present fair saleable value of the assets of such
Guarantor over the amount of all liabilities of such Guarantor, contingent or
otherwise, and (iii) the maximum amount of which this Guaranty is determined
to be enforceable.

     15. Merger; Amendments. This Guaranty is intended as a final expression
of the subject matter hereof and is also intended as a complete and exclusive
statement of the terms hereof. Each Guarantor's liability hereunder is
independent of and in addition to its liability under any other guaranty
previously of subsequently executed. No course of dealing, course of
performance or trade usage, and no parole evidence of any nature, shall be
used to supplement or modify any terms hereof, nor are there any conditions to
the full effectiveness of this Guaranty. None of the terms and provisions of
this Guaranty may be waived, altered, modified or amended in any way except by
an instrument in writing executed by duly authorized officers of each Lender
and the Guarantors.

     16. Consent to Jurisdiction. Notwithstanding the place where any
Liability originates or arises, or is to be repaid, any suit, action or
proceeding arising out of or relating to this Guaranty, any of the Agreements,
or any borrowing made in connection with any of the Agreements, may be
instituted in any court of the United States of America or the State of
Michigan, sitting in the City of Detroit, State of Michigan, or in any court
of the United States of America or the State of Indiana, sitting in the City
of Indianapolis, State of Indiana, and each Guarantor hereby irrevocably
waives any objection which it may have or hereafter have to the laying of the
venue of any such suit, action or proceeding and any claim that any such suit,
action or proceeding has been brought in an inconvenient forum; and each
Guarantor hereby irrevocably submits his person and property to the
jurisdiction of any such court in any such suit, action or proceeding. Each
Guarantor hereby consents to the service of process in any suit, action or
proceeding of the nature referred to in this Paragraph by the mailing of a
copy thereof by registered or certified mail, postage prepaid, or personally
delivering a copy thereof to such Guarantor, at the address set forth under
its signature below, or at such other address as such Guarantor may hereafter
specify to the Lenders in writing. Nothing in this Paragraph shall affect the
right of any Lender to serve process in any other manner permitted by law or
limit the right of the Lenders to bring proceedings against any Guarantor or
any of its property in the courts of any other jurisdiction in which it is
subject to service of process. To the extent that any Guarantor now or
hereafter may be entitled, in any jurisdiction in which proceedings may at any
time be commenced with respect to this Guaranty or the transactions
contemplated hereby, to claim itself or its revenues, assets or properties any
immunity (including, without limitation, immunity from service of process,
jurisdiction, suit, judgment, counterclaim, enforcement of or execution on a
judgment, attachment prior to the judgment, attachment in aid of execution of
a judgment or other legal process), and to the extent that in any such
jurisdiction there may be attributed any such immunity (whether or not
claimed), such Guarantor hereby irrevocably undertakes not to claim and hereby
irrevocably waives any such immunity to the fullest extent permitted by law.
Each Guarantor irrevocably and generally consents in respect of any
proceedings to the giving of any relief or the issue of any process in
connection with those proceedings including, without limitation, the making,
enforcement or execution against any assets whatsoever of any order or
judgment which may be made or given in those proceedings.

     17. Governing Law; Headings. This Guaranty shall be governed by and
construed in accordance with the laws of the State of Michigan without giving
effect to the choice of law principles of such state. The headings of the
various paragraphs hereof are for the convenience of reference only and shall
in no way modify any of the terms or provisions hereof.

     18. Notices. Any notice, demand, consent or request given or made to each
Guarantor by any Lender shall be deemed to have been duly given or made if
sent in writing (including telecommunications) to such Guarantor to the
address or telex or telecopy number set forth below the name of such Guarantor
on the signature page hereof, or at such other address or telex or telecopy
number as such Guarantor may hereafter specify to the Lenders in writing. All
notices or other communications sent by means of telecopy, telex or other wire
transmission shall be made with request for assurance of receipt in a manner
typical with respect to communications of that type. Written notices or other
communications shall be deemed delivered upon receipt if delivered by hand or
by telecopy, three business days after mailing if mailed, or one business day
after deposit with an overnight courier service if delivered by overnight
courier. Notices or other communications delivered by hand shall be deemed
delivered upon receipt.
